    Full Text Available The aim of this study was to identify the problems and determine the conceptual model of regional development planning. Regional development planning is a systemic, complex and unstructured process. Therefore, this study used soft systems methodology to outline unstructured issues with a structured approach. The conceptual models that were successfully constructed in this study are a model of consistency and a model of reconciliation. Regional development planning is a process that is well-integrated with central planning and inter-regional planning documents. Integration and consistency of regional planning documents are very important in order to achieve the development goals that have been set. On the other hand, the process of development planning in the region involves technocratic system, that is, both top-down and bottom-up system of participation. Both must be balanced, do not overlap and do not dominate each other. regional, development, planning, consistency, reconciliation

    In generalized method of data reconciliation as equations of conditions beside substance and energy balances can be used equations which don't have precisely the status of conservation lows. Empirical coefficients in these equations are traded as unknowns' values. To this kind of equations, in application of the generalized method of data reconciliation in supercritical power unit, can be classified: steam flow capacity of a turbine for a group of stages, adiabatic internal efficiency of group of stages, equations for pressure drop in pipelines and equations for heat transfer in regeneration heat exchangers. Mathematical model of a power unit was developed in the code Thermoflex. Using this model the off-design calculation has been made in several points of loads for the power unit. Using these calculations identification of unknown values and empirical coefficients for generalized method of data reconciliation used in power unit has been made. Additional equations of conditions will be used in the generalized method of data reconciliation which will be used in optimization of measurement placement in redundant measurement system in power unit for new control systems

    Full Text Available In South Africa scholars in the broad field of practical theology are currently faced with a daunting challenge: to rethink the reconciling role of the institutional church in the light of continued challenges facing reconciliation within post-apartheid and post-Truth and Reconciliation Commission (TRC South Africa. This contribution investigates whether the transdisciplinary, region-centred scientific research approach with a focus on the Hölderlin perspective on reconciliation could assist scholars in practical theology to address reconciliation in a post-apartheid and post-TRC society. The article proposes a contextual and constructive approach to reconciliation in order to assist South African scholars in the field of practical theology and the institutional church to address the challenges of reconciliation in a post-apartheid and post-TRC society. The contribution confirms that this approach does indeed assist the field of practical theology to contribute to reconciliation without the risk of speaking a language that nobody beyond theology can understand.

  5. Robust data reconciliation with TEMPO

    2004-03-01

    The Halden Project's TEMPO system is devised to meet the increasing challenges facing utilities in performance monitoring and optimisation, among other things due to deregulation and market liberalisation. The data reconciliation mode is an important one in the TEMPO system. Data reconciliation is a method to provide reliable estimates of process states, parameters, the state of equipment and instruments, and efficiency. Data reconciliation follows maximum likelihood principles, and is usually based on a Gaussian error model for the data. Data reconciliation thus estimates the most likely state of the process, given the heat and mass balance and the current instrument readings. If the assumption of normally (Gaussian) distributed errors in the measurements break down, as it will in the case of gross errors (outliers) in the data set, this needs to be detected by the monitoring system. TEMPO does this by computing an overall test statistic subjected to a hypothesis test, resulting in the so-called goodness-of-fit. If the goodness-of-fit takes a too low value, a fault is probably present in the process. Identifying the location of the fault is more difficult, however. With the Gaussian error model this is still possible employing a so-called serial elimination method. The serial elimination method is, however, cumbersome to use and leads to quite lengthy calculations. The present report describes the application of alternative distributions in the maximum likelihood estimation in an attempt to directly identify the location of faulty sensors. For direct identification of sensor faults significant improvements over the method based on a Gaussian error model has been achieved. However, serial elimination still leads to the highest success rate for fault identification. All results were based on Monte Carlo simulations. (Author)

  6. Urban reconciliation ecology: the potential of living roofs and walls.

    2011-06-01

    Reconciling human and non-human use of urban regions to support biological conservation represents a major challenge for the 21st century. The concept of reconciliation ecology, by which the anthropogenic environment may be modified to encourage non-human use and biodiversity preservation without compromising societal utilization, potentially represents an appropriate paradigm for urban conservation given the generally poor opportunities that exist for reserve establishment and ecological restoration in urban areas. Two habitat improvement techniques with great potential for reconciliation ecology in urban areas are the installation of living roofs and walls, which have been shown to support a range of taxa at local scales. This paper evaluates the reconciliation potential of living roofs and walls, in particular highlighting both ecological and societal limitations that need to be overcome for application at the landscape scale. We further consider that successful utilization of living roofs and walls for urban reconciliation ecology will rely heavily on the participation of urban citizens, and that a 'citizen science' model is needed to facilitate public participation and support and to create an evidence base to determine their effectiveness. Living roofs and walls are just one aspect of urban reconciliation ecology, but are particularly important 'bottom-up' techniques for improving urban biodiversity that can be performed directly by the citizenry.

    Full Text Available This paper provides an overview of discourses of the movement for national reconciliation prevailing within the Australian socio-political context since the inception of the Council for Aboriginal Reconciliation in 1991, to the national apology delivered by the Prime Minister Kevin Rudd on 13th February 2008. It provides an framework for the various discourses of reconciliation, by exploring and analysing the accrued meanings to such terms such as ‘genuine’, substantive or ‘true’ reconciliation; the Howard’s Government’s ‘practical reconciliation’ and the Rudd government’s great attempt at ‘symbolic’ reconciliation in the national apology to Indigenous Australians. In the changing political context in Australia today this paper revisits the debates on reconciliation, and endeavours to locate the movement solidly within a human rights framework that includes first nation rights. This requires an examination of the roots of the reconciliation movement including community attitudes to reconciliation and the nature of the peoples’ movement as well as the differing perspectives of policy makers, politicians and of course, Indigenous peoples. It asks crucial questions about the progress of reconciliation and the type of reconciliation mainstream Australians will accept. In truth therefore, was the ‘National Apology’ a grand symbolic gesture by mainstream Australia to maintain the status quo and divert our eyes from the more searching questions of the ‘unfinished business’ of ‘substantive’ reconciliation which encompasses first nations rights for Indigenous peoples.

    2014-01-01

    Medicines reconciliation plays a key role in patient safety. However, there is limited data available on how this process affects critically ill patients. In this study, we evaluate a program of reconciliation in critically ill patients conducted by the Intensive Care Unit's (ICU) pharmacist. Prospective study about reconciliation medication errors observed in 50 patients. All ICU patients, excluding patients without regular treatment. Reconciliation process was carried out in the first 24h after ICU admission. Discrepancies were clarified with the doctor in charge of the patient. We analyzed the incidence of reconciliation errors, their characteristics and gravity, the interventions made by the pharmacist and their acceptance by physicians. A total of 48% of patients showed at least one reconciliation error. Omission of drugs accounted for 74% of the reconciliation errors, mainly involving antihypertensive drugs (33%). An amount of 58% of reconciliation errors detected corresponded to severity category D. Pharmacist made interventions in the 98% of patients with discrepancies. A total of 81% of interventions were accepted. The incidence and characteristics of reconciliation errors in ICU are similar to those published in non-critically ill patients, and they affect drugs with high clinical significance. Our data support the importance of the stablishment of medication reconciliation proceedings in critically ill patients. The ICU's pharmacist could carry out this procedure adequately.

  11. Data-Reconciliation Based Fault-Tolerant Model Predictive Control for a Biomass Boiler

    Directory of Open Access Journals (Sweden)

    Palash Sarkar

    2017-02-01

    Full Text Available This paper presents a novel, effective method to handle critical sensor faults affecting a control system devised to operate a biomass boiler. In particular, the proposed method consists of integrating a data reconciliation algorithm in a model predictive control loop, so as to annihilate the effects of faults occurring in the sensor of the flue gas oxygen concentration, by feeding the controller with the reconciled measurements. Indeed, the oxygen content in flue gas is a key variable in control of biomass boilers due its close connections with both combustion efficiency and polluting emissions. The main benefit of including the data reconciliation algorithm in the loop, as a fault tolerant component, with respect to applying standard fault tolerant methods, is that controller reconfiguration is not required anymore, since the original controller operates on the restored, reliable data. The integrated data reconciliation–model predictive control (MPC strategy has been validated by running simulations on a specific type of biomass boiler—the KPA Unicon BioGrate boiler.

  12. Pareto-optimal phylogenetic tree reconciliation.

    2014-06-15

    Phylogenetic tree reconciliation is a widely used method for reconstructing the evolutionary histories of gene families and species, hosts and parasites and other dependent pairs of entities. Reconciliation is typically performed using maximum parsimony, in which each evolutionary event type is assigned a cost and the objective is to find a reconciliation of minimum total cost. It is generally understood that reconciliations are sensitive to event costs, but little is understood about the relationship between event costs and solutions. Moreover, choosing appropriate event costs is a notoriously difficult problem. We address this problem by giving an efficient algorithm for computing Pareto-optimal sets of reconciliations, thus providing the first systematic method for understanding the relationship between event costs and reconciliations. This, in turn, results in new techniques for computing event support values and, for cophylogenetic analyses, performing robust statistical tests. We provide new software tools and demonstrate their use on a number of datasets from evolutionary genomic and cophylogenetic studies.

    2009-12-19

    The procedure known as data reconciliation is based on measurement adjustments so that the resulting values fit within the conservation laws and the restrictions imposed by the process. The classical general data reconciliation problem deals with a weighted least-squares minimization of the measurement adjustments subject to the model constraints. The reconciliation technique allows that two or more experimental redundant measurements can be reconciled to a single value, a better representation of the quantity to be analyzed, minimizing the measurement uncertainty. A critical step in this process is the acquisition and storage of long-term data. There are commercial applications available to solve this problem, although in many cases they don't apply to the plants particularities and, in cases they do, the presented solution is usually more complex and expensive. The purpose of this work was to develop a custom tool for volume data reconciliation on oil products storage and transportation plants using the process data stored on a PIMS server. The platform chosen for this development was an Excel environment. The main novelty presented in this tool is the intrinsic simplicity gained by using an Excel environment, due to its wide range usage facilitating the customization for different plants without extra costs for the company.

  14. Exact Algorithms for Duplication-Transfer-Loss Reconciliation with Non-Binary Gene Trees.

    Kordi, Misagh; Bansal, Mukul S

    2017-06-01

    Duplication-Transfer-Loss (DTL) reconciliation is a powerful method for studying gene family evolution in the presence of horizontal gene transfer. DTL reconciliation seeks to reconcile gene trees with species trees by postulating speciation, duplication, transfer, and loss events. Efficient algorithms exist for finding optimal DTL reconciliations when the gene tree is binary. In practice, however, gene trees are often non-binary due to uncertainty in the gene tree topologies, and DTL reconciliation with non-binary gene trees is known to be NP-hard. In this paper, we present the first exact algorithms for DTL reconciliation with non-binary gene trees. Specifically, we (i) show that the DTL reconciliation problem for non-binary gene trees is fixed-parameter tractable in the maximum degree of the gene tree, (ii) present an exponential-time, but in-practice efficient, algorithm to track and enumerate all optimal binary resolutions of a non-binary input gene tree, and (iii) apply our algorithms to a large empirical data set of over 4700 gene trees from 100 species to study the impact of gene tree uncertainty on DTL-reconciliation and to demonstrate the applicability and utility of our algorithms. The new techniques and algorithms introduced in this paper will help biologists avoid incorrect evolutionary inferences caused by gene tree uncertainty.

    Medication errors can result from administration inaccuracies at any point of care and are a major cause for concern. To develop a successful Medication Reconciliation (MR) tool, we believe it necessary to build a Work Domain Ontology (WDO) for the MR process. A WDO defines the explicit, abstract, implementation-independent description of the task by separating the task from work context, application technology, and cognitive architecture. We developed a prototype based upon the WDO and designed to adhere to standard principles of interface design. The prototype was compared to Legacy Health System's and Pre-Admission Medication List Builder MR tools via a Keystroke-Level Model analysis for three MR tasks. The analysis found the prototype requires the fewest mental operations, completes tasks in the fewest steps, and completes tasks in the least amount of time. Accordingly, we believe that developing a MR tool, based upon the WDO and user interface guidelines, improves user efficiency and reduces cognitive load.

  17. Reconciliation with non-binary species trees.

    2008-10-01

    Reconciliation extracts information from the topological incongruence between gene and species trees to infer duplications and losses in the history of a gene family. The inferred duplication-loss histories provide valuable information for a broad range of biological applications, including ortholog identification, estimating gene duplication times, and rooting and correcting gene trees. While reconciliation for binary trees is a tractable and well studied problem, there are no algorithms for reconciliation with non-binary species trees. Yet a striking proportion of species trees are non-binary. For example, 64% of branch points in the NCBI taxonomy have three or more children. When applied to non-binary species trees, current algorithms overestimate the number of duplications because they cannot distinguish between duplication and incomplete lineage sorting. We present the first algorithms for reconciling binary gene trees with non-binary species trees under a duplication-loss parsimony model. Our algorithms utilize an efficient mapping from gene to species trees to infer the minimum number of duplications in O(|V(G) | x (k(S) + h(S))) time, where |V(G)| is the number of nodes in the gene tree, h(S) is the height of the species tree and k(S) is the size of its largest polytomy. We present a dynamic programming algorithm which also minimizes the total number of losses. Although this algorithm is exponential in the size of the largest polytomy, it performs well in practice for polytomies with outdegree of 12 or less. We also present a heuristic which estimates the minimal number of losses in polynomial time. In empirical tests, this algorithm finds an optimal loss history 99% of the time. Our algorithms have been implemented in NOTUNG, a robust, production quality, tree-fitting program, which provides a graphical user interface for exploratory analysis and also supports automated, high-throughput analysis of large data sets.

  19. On the Complexity of Duplication-Transfer-Loss Reconciliation with Non-Binary Gene Trees.

    Kordi, Misagh; Bansal, Mukul S

    2017-01-01

    Duplication-Transfer-Loss (DTL) reconciliation has emerged as a powerful technique for studying gene family evolution in the presence of horizontal gene transfer. DTL reconciliation takes as input a gene family phylogeny and the corresponding species phylogeny, and reconciles the two by postulating speciation, gene duplication, horizontal gene transfer, and gene loss events. Efficient algorithms exist for finding optimal DTL reconciliations when the gene tree is binary. However, gene trees are frequently non-binary. With such non-binary gene trees, the reconciliation problem seeks to find a binary resolution of the gene tree that minimizes the reconciliation cost. Given the prevalence of non-binary gene trees, many efficient algorithms have been developed for this problem in the context of the simpler Duplication-Loss (DL) reconciliation model. Yet, no efficient algorithms exist for DTL reconciliation with non-binary gene trees and the complexity of the problem remains unknown. In this work, we resolve this open question by showing that the problem is, in fact, NP-hard. Our reduction applies to both the dated and undated formulations of DTL reconciliation. By resolving this long-standing open problem, this work will spur the development of both exact and heuristic algorithms for this important problem.

  20. The Influence of Organizational Reconciliation Policies and Culture on Workers Stress Perceptions

    Full Text Available Work-family reconciliation plays a crucial role in the well-being of employees, having impacts at the individual, social and organizational level. Studies concluded that poor work-life balance as one of the ten predictors of psychosocial risks at work. A family-friendly culture relates to how an organization values and allows the articulation of the various spheres of its workers’ life. We intended to determine the effect of different variables like the existence of services, the organizational culture and the managers and colleagues support, on the stress experienced. A sample of 156 employees, from five organizations in the same region of Portugal, responded to a survey contributing to the empirical results of the study. We have conducted a structural equation model to test whether the factor solution of the perception of the reconciliation capability - STRESS model demonstrated a goodness of fit to the population studied. We’ve concluded that more important than the existence of reconciliation services, the perception of a supportive organizational culture, namely by colleagues and supervisors has great influence in reconciliation capability and by that way on work stress feelings. This might explain why workers do not use all the spectrum of resources provided by organizations and states to work-life reconciliation.

    2013-01-01

    Medication reconciliation is integral to every hospital. Approximately 60 percent of all hospital medication errors occur at admission, intra-hospital transfer or discharge. Effectively and consistently performing medication reconciliation at care-interfaces continues to be a challenge. Tan Tock Seng Hospital (TTSH) averages 4,700 admissions monthly. Many patients are elderly (> 65 years old) at risk from poly-pharmacy. As part of a medication safety initiative, pharmacy staff started a medication reconciliation service in 2007, which expanded to include all patients in October 2009. This article aims to describe the TTSH medication reconciliation system and to highlight common medication errors occurring following incomplete medication reconciliation. Where possible, patients admitted into TTSH are seen by pharmacy staff within 24 hours of admission. A form was created to document their medications, which is filed into the case sheets for referencing purposes. Any discrepancies in medicines are brought to doctors' attention. Patients are also counseled about changes to their medications. Errors picked up were captured in an Excel database. The most common medication error was prescribers missing out medications. The second commonest was recording different doses and regimens. The reason was mainly due to doctors transcribing medications inaccurately. This is a descriptive study and no statistical tests were carried out. Data entry was done by different pharmacy staff, and not a dedicated person; hence, data might be under-reported. The findings demonstrate the importance of medication reconciliation on admission. Accurate medication reconciliation can help to reduce transcription errors and improve service quality. The article highlights medication reconciliation's importance and has implications for healthcare professionals in all countries.

    2017-01-01

    Quantum key distribution (QKD) is a quantum-proof key-exchange scheme which is fast approaching the communication industry. An essential component in QKD is the information reconciliation step, which is used for correcting the quantum-channel noise errors. The recently suggested blind-reconciliation technique, based on low-density parity-check codes, offers remarkable prospectives for efficient information reconciliation without an a priori quantum bit error rate estimation. We suggest an improvement of the blind-information-reconciliation protocol promoting a significant increase in the efficiency of the procedure and reducing its interactivity. Finally, the proposed technique is based on introducing symmetry in operations of parties, and the consideration of results of unsuccessful belief-propagation decodings.

To extend the process of reconciliation at hospital discharge from the Cardiology and Chest Diseases departments. Retrospective observational study that included patients over 75 years old. The "Consensus Document on Terminology and Classification in Medication Reconciliation" was used for the classification of the discrepancies found. Potentially inappropriate prescriptions and drug interactions were reviewed. For reconciliation at discharge, a "Drug information program at discharge" leaflet and a "Patient information sheet" was developed. The number of reconciled patients was 818, with a level of coverage of 42.3% (target patients: 1,932). Reconciliation errors by patient were 23.4% (191) on admission and 22.5% (9) at discharge. All patients who were reconciled at discharge were given the "Drug information program at discharge" leaflet. Potentially inappropriate prescriptions, according to STOPP/START criteria, affected 6.0% (49) of reconciled patients. The number of clinically relevant interactions affected 11.7% (96) of patients. The implementation of a reconciliation process has detected the existence of errors between chronic and prescribed treatment in the hospital. The STOPP/START criteria applied to this group of patients have helped to find out the most common potentially inappropriate prescriptions. The analysis of drug interactions shows drug combinations that should be avoided in these patients. Copyright © 2016 SECA. Published by Elsevier Espana. All rights reserved.

    Information reconciliation is a significant step for a continuous-variable quantum key distribution (CV-QKD) system. We propose a reconciliation method that allows two authorized parties to extract a consistent and secure binary key in a CV-QKD protocol, which is based on Gaussian-modulated coherent states and homodyne detection. This method named spherical reconciliation is based on spherical quantization and non-binary low-density parity-check (LDPC) codes. With the suitable signal-to-noise ratio (SNR) and code rate of non-binary LDPC codes, spherical reconciliation algorithm has a high efficiency and can extend the transmission distance of CV-QKD.

Of concern is the liturgical situation in which, sermons about reconciliation take place � the� homiletic process through which a homiletic theory is established, the sermon as a work of art and its structure. All these liturgical and homiletic motivators release energy, which enables preaching about reconciliation to take place in a way that moves the listener. Reconciliation means to overcome the divide between the rich and the poor and looking at other people the other person through different eyes.

    .7% were rated as potentially harmful. A multivariate logistic regression model showed that patients aged ≥65 years, polypharmacy, and prescriptions for hypoglycemic drugs and warfarin were more likely associated with reconciliation errors. Conclusion: There is a high failure rate in medication reconciliation process in patients admitted to the medical and surgical department. The reconciliation process proves to be a useful tool since nearly half of avoided reconciliation errors were unintentional and had the potential for harm. This strategy, based on our results and the difficulty of applying the process to all patients should be directed primarily to the patients at increased risk of error.

    This report is an appendix to the 'Environmental Impact Assessment - Interim storage, encapsulation and disposal of spent nuclear fuel'. The report makes a reconciliation with how the national and regional environmental quality and public health objectives are met in the construction, operation and decommissioning of the encapsulation plant and final disposal facility, and the Clink (encapsulation facility combined with CLAB). The starting point for reconciliation is the Environmental Impact Assessment (EIA). This report provides reconciliations against how the environmental and health objectives are met. A more detailed description of the business and its environmental impacts is provided in the EIA.The disposal facility is planned to be constructed in Forsmark municipality, Oesthammar and the encapsulation is constructed, combined with CLAB, in Simpevarp in Oskarshamn municipality

  14. Schedule reconciliation tests for management prudency determination

    Howell, G.E.

    1986-01-01

    The prudency audit of a nuclear project involves engineering, construction, financial, and management dimensions. The audit must retrospectively evaluate the decisions and actions of management decision makers and then equitably allocate the cost impacts of those decisions and actions in a comprehensive and objective manner. In most situations, determination of the impact of schedule delays is a paramount issue. Manzi and Associates uses an approach to schedule reconciliation that focuses on the site-specific, as-built condition. The as-built schedule model is analyzed by a backward pass, or but-for methodology which focuses on the causes and impacts of identified delays. The objective is to demonstrate that but-for the identified delay, the project could have been built in the as-planned time frame. The but-for methodology has been used in many contract dispute cases and is currently being applied to schedule reconciliation on several nuclear plants. The potential for applying this methodology to both new construction and retrofit projects is great

    Full Text Available Preventable adverse drug events occur frequently at transitions in care and are a problem for many patients following hospital discharge. Many of these problems can be attributed to poor medication reconciliation. The purpose of this study was to assess the impact that direct pharmacist involvement in the discharge medication reconciliation process had on medication discrepancies, patient outcomes, and satisfaction. A cohort study of 70 patients was designed to assess the impact of pharmacist facilitated discharge medication reconciliation at a 204-bed community hospital in Battle Creek, Michigan, USA. Discharge summaries were analyzed to compare patients who received standard discharge without pharmacist involvement to those having pharmacist involvement. The total number of discrepancies in the group without pharmacist involvement was significantly higher than that of the pharmacist facilitated group.

    Full Text Available Objective: To measure length of hospital stay (LHS in patients receiving medication reconciliation. Secondary characteristics included analysis of number of preadmission medications, medications prescribed at admission, number of discrepancies, and pharmacists interventions done and accepted by the attending physician. Methods: A 6 month, randomized, controlled trial conducted at a public teaching hospital in southern Brazil. Patients admitted to general wards were randomized to receive usual care or medication reconciliation, performed within the first 72 hours of hospital admission. Results: The randomization process assigned 68 patients to UC and 65 to MR. LHS was 10±15 days in usual care and 9±16 days in medication reconciliation (p=0.620. The total number of discrepancies was 327 in the medication reconciliation group, comprising 52.6% of unintentional discrepancies. Physicians accepted approximately 75.0% of the interventions. Conclusion: These results highlight weakness at patient transition care levels in a public teaching hospital. LHS, the primary outcome, should be further investigated in larger studies. Medication reconciliation was well accepted by physicians and it is a useful tool to find and correct discrepancies, minimizing the risk of adverse drug events and improving patient safety.

    The project has shown that model-based data reconciliation can be used in heat and power plants, but it needs support of soft sensors. Generally power plants are not equipped with more sensors than required by control systems, environment and financial reports. Soft sensors are needed to compensate for lack of redundancy in mass-flow sensors. Redundancy makes it possible to isolate gross errors. The smallest error needed to be determined sets the requirement on the process model accuracy. Tools available today from this project are; classification of different process sections with redundancy analysis and gross error detection. Quantification of the errors with the mass balance model has not been successful and this part needs further development. Theoretical comparison of the three different methods presented resulted in favour of data reconciliation based on a mass balance model. The mass balance model has a structure based on physical reality. The searches for gross errors are transparent to the user. It can handle sensor failure. The statistical linear model is preferred for smaller process sections when transparency is not needed and focus is on fast, simple and cheap implementation. Data reconciliation based on steady-state energy balance has the same origin as the mass balance model. Data reconciliation based on energy balance is harder to compute and its sensors difficult to classify. The drawback is complexity, but the strength is that the large number of temperature sensors can be used in the data reconciliation. Large gross errors are detected and quantified for most process mass flows with acceptable accuracy. Performances for small errors are not as good. Performance of the data reconciliation is strongly dependent on precision in the process models. This conclusion is drawn from comparison with other studies that show good performance for laboratory simulations. There are still many parts to develop further as: Soft sensors, tests for identification

    Full Text Available However despotic a social group may be, managing conflicts of interest is crucial to preserve group living benefits, mainly based on cooperation. In despotic groups, post-conflict management via reconciliation (the first post-conflict reunion between former opponents can occur, even if conciliatory rates are considerably different. Lemur catta is defined as a despotic species because groups are characterized by a strict linear hierarchy maintained by the adult females (the dominant sex mainly via aggression. Reconciliation was reported in one out of four captive groups of L. catta. Here we investigate which variables influence the occurrence of reconciliation in these despotic groups. We analyzed 2339 Post Conflict (PC-Matched Control (MC observation pairs, collected on eight groups (five in the Berenty forest, Madagascar; three hosted at the Pistoia Zoo, Italy. Since L. catta is characterized by steep female dominance but shows female-female coalitionary support, we expected to confirm the presence of reconciliation in the study species. Consistently, we found reconciliation in one captive group and two wild groups, thus providing the first evidence of the presence of this phenomenon in wild L. catta. Moreover, because this species is a seasonal breeder (with mating occurring once a year, we expected seasonal fluctuations in reconciliation levels. Via a GLMM analysis using data from all wild groups and on a captive group followed for more than one year, we found that season (but not rank; individuals' identity, sex, and age; or group identity significantly affected individual reconciliation rates, and such rates were lowest during the mating period. Thus, reconciliation can be present in groups in which dominants strongly influence and limit social relationships (steep dominance hierarchy except when the advantages of intra-group cooperation are overcome by competition, as occurs in seasonal breeders when reproduction is at stake. We conclude

    Full Text Available This article aims to understand what role Steve Biko and the Black Consciousness Movement, and the Soweto Uprising, played in Christian activism between the early 1970s and late 1980s. The question is: did the Black Consciousness Movement and the Soweto Uprising influence Christian activists to engage differently with notions such as reconciliation during the struggle against apartheid? The article revisits the actions and thinking of Christian activists before 1994 to understand some of their views on reconciliation, but most importantly, to understand their interactions, engagement with the Black Consciousness Movement and the Soweto Uprising. The article focuses on some of the church leaders and liberation theologians who were inspired and encouraged by Black Consciousness movements, including Allan Boesak and Desmond Tutu. To revisit their thinking and actions, in the heart of the struggle against apartheid, may help us understand current struggles on reconciliation, particularly in connection with the new generation of activists known as the Fallists. We may discover that the new generation is opening ‘old or new’ debates around reconciliation in South Africa.

    Full Text Available Objective: The objective of this study is to conduct a review of pertinent literature, assess pharmacy involvement in medication reconciliation, and offer insight into best practices for hospitals to implement and enhance their medication reconciliation programs. Method: Pharmacists in hospitals nationwide were asked to complete an anonymous survey via the American College of Clinical Pharmacy online database. The multiple choice survey analyzed the roles that healthcare professionals play in medication reconciliation programs at hospitals. Results: Of the survey responses received, 32/91 (35% came from pharmacists at hospitals with a pharmacy-led medication reconciliation program. Of these pharmacy-led programs, 17/32 (53% have a dedicated pharmacist or pharmacy staff to perform medication reconciliation. Conclusion: A comprehensive review of literature suggests that pharmacy involvement has the potential to reduce medication reconciliation errors and may improve patient satisfaction. Focused, full-time medication reconciliation pharmacists can help hospitals save time and money, improve outcomes, and meet higher standards issued by the Joint Commission. Data obtained in this study show the extent to which pharmacists contribute to achieving these goals in healthcare systems nationwide. This baseline study provides a strong case for hospitals to implement a pharmacy-led medication reconciliation program.

    Full Text Available Employing a reflexive and co-constructed narrative analysis, this article explores our experiences as a non-Indigenous doctoral student and a First Nations research assistant working together within the context of a community-based participatory Indigenous geography research project. Our findings revealed that within the research process there were experiences of conflict, and opportunities to reflect upon our identity and create meaningful relationships. While these experiences contributed to an improved research process, at a broader level, we suggest that they also represented our personal stories of reconciliation. In this article, we share these stories, specifically as they relate to reconciliatory processes of re-education and cultural regeneration. We conclude by proposing several policy recommendations to support research as a pathway to reconciliation in Canada.

    Full Text Available Objective: To analyze the outcomes of a medication reconciliation process at admission in the hospital setting. To assess the role of the Pharmacist in detecting reconciliation errors and preventing any adverse events entailed. Method: A retrospective study was conducted to analyze the medication reconciliation activity during the previous six months. The study included those patients for whom an apparently not justified discrepancy was detected at admission, after comparing the hospital medication prescribed with the home treatment stated in their clinical hospital records. Those patients for whom the physician ordered the introduction of home medication without any specification were also considered. In order to conduct the reconciliation process, the Pharmacist prepared the best pharmacotherapeutical history possible, reviewing all available information about the medication the patient could be taking before admission, and completing the process with a clinical interview. The discrepancies requiring clarification were reported to the physician. It was considered that the reconciliation proposal had been accepted if the relevant modification was made in the next visit of the physician, or within 24-48 hours maximum; this case was then labeled as a reconciliation error. For the descriptive analysis, the Statistics® SPSS program, version 17.0, was used. Outcomes: 494 medications were reconciled in 220 patients, with a mean of 2.25 medications per patient. More than half of patients (59.5% had some discrepancy that required clarification; the most frequent was the omission of a medication that the patient was taking before admission (86.2%, followed by an unjustified modification in dosing or way of administration (5.9%. In total, 312 discrepancies required clarification; out of these, 93 (29.8% were accepted and considered as reconciliation errors, 126 (40% were not accepted, and in 93 cases (29,8% acceptance was not relevant due to a change in

Data reconciliation is formulated by a constrained minimization problem, where the constraints correspond to energy and mass balance model.

    2014-01-01

    Full Text Available The first part of the paper briefly overviews the problem of gene and species trees reconciliation with the focus on defining and algorithmic construction of the evolutionary scenario. Basic ideas are discussed for the aspects of mapping definitions, costs of the mapping and evolutionary scenario, imposing time scales on a scenario, incorporating horizontal gene transfers, binarization and reconciliation of polytomous trees, and construction of species trees and scenarios. The review does not intend to cover the vast diversity of literature published on these subjects. Instead, the authors strived to overview the problem of the evolutionary scenario as a central concept in many areas of evolutionary research. The second part provides detailed mathematical proofs for the solutions of two problems: (i inferring a gene evolution along a species tree accounting for various types of evolutionary events and (ii trees reconciliation into a single species tree when only gene duplications and losses are allowed. All proposed algorithms have a cubic time complexity and are mathematically proved to find exact solutions. Solving algorithms for problem (ii can be naturally extended to incorporate horizontal transfers, other evolutionary events, and time scales on the species tree.

    2016-03-01

    Full Text Available doi: http://dx.doi.org/10.15447/sfews.2016v14iss1art5Floodplains in California and elsewhere are productive natural habitats with high levels of biodiversity, yet today they are often permanently disconnected from rivers by urban or agricultural development and flood management structures. This disconnection poses a threat to many native fish, bird and other species that evolved to take advantage of seasonal floodplain inundation. The traditional restoration approach to this problem is to recreate historical floodplain by restoring natural hydrologic and successional processes. However levees, dams, and development have made this largely impossible in much of the developed world. Reconciliation ecology recognizes this limitation, and encourages instead the re-engineering of human dominated landscapes to allow for coexistence of native species and human uses. Flood control bypasses are particularly promising places to reconcile historical fish and bird uses of floodplain habitats with human uses. However, the reconciliation approach requires nuanced management of a complex system. Using the Yolo Basin flood bypass in California’s Central Valley as an example, this study develops formal multi-objective optimization to help planners identify management options that best improve habitat quality for fish and birds with minimal costs to farmers or wetland managers. Models like the one developed here can integrate large amounts of data and knowledge, and offer an explicit accounting of relationships and trade-offs between different objectives. This is especially useful in reconciliation planning, where many uses and variables interact on a landscape, and deliberate re-engineering requires consideration of many decisions simultaneously. Initial results suggest that modest land-use changes and inundation management strategies can significantly improve seasonal bird and fish habitat quality at little cost to farmers or other human land uses.

    Full Text Available Truth commissions and trials have been applauded as the way to move on from a violent past. Yet, some post-conflict societies managed to move toward reconciliation without the presence, or the effective presence of such formal institutions. This article discusses a number of lessons learned from Maluku, where reconciliation took the interdependence path. Taking on an interpretive, emic approach, it elaborates on the sites and mechanisms of interpendence. It argues that interdependence can be as viable as truth and justice procedures in bringing about reconciliation.

    Reconciliation is a significant procedure in a continuous-variable quantum key distribution (CV-QKD) system. It is employed to extract secure secret key from the resulted string through quantum channel between two users. However, the efficiency and the speed of previous reconciliation algorithms are low. These problems limit the secure communication distance and the secure key rate of CV-QKD systems. In this paper, we proposed a high-speed reconciliation algorithm through employing a well-structured decoding scheme based on low density parity-check (LDPC) code. The complexity of the proposed algorithm is reduced obviously. By using a graphics processing unit (GPU) device, our method may reach a reconciliation speed of 25 Mb/s for a CV-QKD system, which is currently the highest level and paves the way to high-speed CV-QKD.

    2016-01-01

    Efficient reconciliation is a crucial step in continuous variable quantum key distribution. The progressive-edge-growth (PEG) algorithm is an efficient method to construct relatively short block length low-density parity-check (LDPC) codes. The qua-sicyclic construction method can extend short block length codes and further eliminate the shortest cycle. In this paper, by combining the PEG algorithm and qua-si-cyclic construction method, we design long block length irregular LDPC codes with high error-correcting capacity. Based on these LDPC codes, we achieve high-efficiency Gaussian key reconciliation with slice recon-ciliation based on multilevel coding/multistage decoding with an efficiency of 93.7%.

  1. Simulation Based Data Reconciliation for Monitoring Power Plant Efficiency

    International Nuclear Information System (INIS)

    Park, Sang Jun; Heo, Gyun Young

    2010-01-01

    Power plant efficiency is analyzed by using measured values, mass/energy balance principles, and several correlations. Since the measured values can have uncertainty depending on the accuracy of instrumentation, the results of plant efficiency should definitely have uncertainty. The certainty may occur due to either the randomness or the malfunctions of a process. In order to improve the accuracy of efficiency analysis, the data reconciliation (DR) is expected as a good candidate because the mathematical algorithm of the DR is based on the first principles such as mass and energy balance considering the uncertainty of instrumentation. It should be noted that the mass and energy balance model for analyzing power plant efficiency is equivalent to a steady-state simulation of a plant system. Therefore the DR for efficiency analysis necessitates the simulation which can deal with the uncertainty of instrumentation. This study will propose the algorithm of the simulation based DR which is applicable to power plant efficiency monitoring

    2017-01-01

    This article analyses the Juba peace negotiations on accountability and reconciliation.

    2006-07-01

      This article, while not uncritical of the Commission, is generally positive about its contribution both in attempting to deal with the past, and in building a democratic, human rights and restorative justice culture based on the rule of law. It examines the definitions of reconciliation that emerged during the Commission in the light of a Christian definition where reconciliation is seen to be between God, others and self, and involves integration with the human community. This integration involves taking responsibility for the past, confession and repentance, forgiving and being forgiven, making restitution where possible, ongoing transformation in the present and hope for the future.

    Sheikh Khalifa Medical City (SKMC) in Abu Dhabi is the main tertiary care referral hospital in the United Arab Emirates (UAE) with 560 bed capacity that is fully occupied most of the time. SKMC senior management has made a commitment to make quality and patient safety a top priority. Our governing body Abu Dhabi Health Services Company has identified medication reconciliation as a critical patient safety measure and key performance indicator (KPI). The medication reconciliation electronic form a computerized decision support tool was introduced to improve medication reconciliation compliance on transition of care at admission, transfer and discharge of patients both in the inpatient and outpatient settings. In order to improve medication reconciliation compliance a multidisciplinary task force team was formed and led this quality improvement project. The purpose of this publication is to indicate the quality improvement interventions implemented to enhance compliance with admission medication reconciliation and the outcomes of those interventions. We chose to conduct the pilot study in general medicine as it is the busiest department in the hospital, with an average of 390 patients admitted per month during the study period. The study period was from April 2014 till October 2015 and a total of 8576 patients were evaluated. The lessons learned were disseminated throughout the hospital. Our aim was to improve admission medication reconciliation compliance using the electronic form in order to ensure patient safety and reduce preventable harm in terms of medication errors. Admission medication reconciliation compliance improved in general medicine from 40% to above 85%, and this improvement was sustained for the last four months of the study period. PMID:27822371

  7. A Bridge to Reconciliation: A Critique of the Indian Residential School Truth Commission

    2010-05-01

    Full Text Available In the past year, the Government of Canada has established the Indian Residential Schools (IRS Truth and Reconciliation Commission (TRC to address the deleterious effect that the IRS system has had on Aboriginal communities. This paper argues that the TRC as an alternative dispute resolution mechanism is flawed since it focuses too much on truth at the expense of reconciliation. While the proliferation of historical truths is of great importance, without mapping a path to reconciliation, the Canadian public will simply learn about the mistakes of the past without addressing the residual, communal impacts of the IRS system that continue to linger. The Truth and Reconciliation Commission must therefore approach its mandate broadly and in a manner reminiscent of the Royal Commission on Aboriginal Peoples of 1996.

    2003-01-01

    We describe an error-reconciliation protocol, which we call Winnow, based on the exchange of parity and Hamming's 'syndrome' for N-bit subunits of a large dataset. The Winnow protocol was developed in the context of quantum-key distribution and offers significant advantages and net higher efficiency compared to other widely used protocols within the quantum cryptography community. A detailed mathematical analysis of the Winnow protocol is presented in the context of practical implementations of quantum-key distribution; in particular, the information overhead required for secure implementation is one of the most important criteria in the evaluation of a particular error-reconciliation protocol. The increase in efficiency for the Winnow protocol is largely due to the reduction in authenticated public communication required for its implementation

    2011-12-01

    The purpose of this qualitative descriptive study was to describe medication reconciliation practices in nursing homes with a specific focus on nursing staff involvement in the process. The study was conducted in eight Midwestern nursing homes and included 46 onsite observations of resident transfers to the nursing home. Informal interviews of nursing staff performing medication reconciliation were conducted during each observation. Findings suggest nursing home nursing staff, including both RN and licensed practical nurse (LPN) staff, were primarily responsible for performing medication reconciliation; however, these staff often varied in how they processed resident transfer information to identify medication order discrepancies. Patterns of differences were found related to their perceptions about medication reconciliation, as well as their actions when performing the process. RN staff were more often focused on resident safety and putting the "big picture" together, whereas LPN staff were more often focused on the administrative assignment and "completing the task."

    Whether employed and nonemployed mothers of children with intellectual disability (ID) have different experiences with reconciliation between care and work has rarely been explored. A survey was conducted in a county in Taiwan and 487 mothers aged younger than 65 and having a child with ID were interviewed face to face at their homes to explore whether there are different factors related to the reconciliation between care and work among employed and nonemployed mothers. Except for the common ground of mothers' health and care demands, logistic regression revealed work flexibility and care support were important for employed mothers. In contrast, the success of reconciliation for nonemployed mothers was determined by their individual characteristics (i.e., age, marital status, family income). Reconciliation policies for mothers with different employment statuses need to use different strategies.

    Many countries require hospitals to implement medication reconciliation for accreditation, but the process is resource-intensive, thus adherence is poor. We report on the impact of prepopulating and aligning community and hospital drug lists with data from population-based and hospital-based drug information systems to reduce workload and enhance adoption and use of an e-medication reconciliation application, RightRx. The prototype e-medical reconciliation web-based software was developed for a cluster-randomized trial at the McGill University Health Centre. User-centered design and agile development processes were used to develop features intended to enhance adoption, safety, and efficiency. RightRx was implemented in medical and surgical wards, with support and training provided by unit champions and field staff. The time spent per professional using RightRx was measured, as well as the medication reconciliation completion rates in the intervention and control units during the first 20 months of the trial. Users identified required modifications to the application, including the need for dose-based prescribing, the role of the discharge physician in prescribing community-based medication, and access to the rationale for medication decisions made during hospitalization. In the intervention units, both physicians and pharmacists were involved in discharge reconciliation, for 96.1% and 71.9% of patients, respectively. Medication reconciliation was completed for 80.7% (surgery) to 96.0% (medicine) of patients in the intervention units, and 0.7% (surgery) to 82.7% of patients in the control units. The odds of completing medication reconciliation were 9 times greater in the intervention compared to control units (odds ratio: 9.0, 95% confidence interval, 7.4-10.9, P < .0001) after adjusting for differences in patient characteristics. High rates of medication reconciliation completion were achieved with automated prepopulation and alignment of community and hospital

  13. An African Perspective on Peace Education: Ubuntu Lessons in Reconciliation

    Science.gov (United States)

    Murithi, Tim

    2009-05-01

    This essay examines the value of educating for peace. It does this through a consideration of the African cultural world-view known as ubuntu, which highlights the essential unity of humanity and emphasises the importance of constantly referring to the principles of empathy, sharing and cooperation in efforts to resolve our common problems. The essay is not based on field research, but rather on a discussion of the issues pertaining to ubuntu and peace education. The discussion focuses on how Desmond Tutu utilised the principles of ubuntu during his leadership of the South African Truth and Reconciliation Commission. It also outlines the five stages of the peacemaking process found among ubuntu societies: acknowledging guilt; showing remorse and repenting; asking for and giving forgiveness; and paying compensation or reparations as a prelude to reconciliation. Potential lessons for educating for peace and reconciliation are highlighted based on the premise that the ubuntu approach to human relationship-building can offer an example to the world.

    2015-11-01

    Full Text Available Armed violence and genocide are among the on-going problems that are still facing contemporary Africa and the world. In the aftermath of the outrages, devastation and appalling carnage of the Second World War, member states of the United Nations (UN undertook radical steps, inter alia, "to save succeeding generations from the scourge of war and to reaffirm faith in fundamental human rights". Subsequently, the International Bill of Human Rights was proclaimed in order to lay down international human rights norms and standards of conduct and to prevent the recurrence of mass killings. Although Burundi is a State Party to the UN and African Union and is a signatory to a number of international and regional human rights treaties, the post-colonial history of Burundi is an epic tale of indescribable human suffering and misery as a result of systematic mass killings. At least every family or household in Burundi has been negatively affected by the mass killings of the 1960s, 1972, 1988 and 1990s, which have created a significant number of refugees and internally displaced persons (IDPs.This article traces the root causes of Burundi's systemic armed violence and argues that despite several UN Security Council Resolutions and peace agreements aimed at national reconciliation and reconstruction, mass killings and other heinous crimes remain unaddressed. The article recommends that a comprehensive transitional justice model is required in post-conflict Burundi in order to bring about national reconciliation, healing and reconstruction.

    Given a gene and a species tree, reconciliation methods attempt to retrieve the macro-evolutionary events that best explain the discrepancies between the two tree topologies. The DTL parsimonious approach searches for a most parsimonious reconciliation between a gene tree and a (dated) species tree, considering four possible macro-evolutionary events (speciation, duplication, transfer, and loss) with specific costs. Unfortunately, many events are erroneously predicted due to errors in the input trees, inappropriate input cost values or because of the existence of several equally parsimonious scenarios. It is thus crucial to provide a measure of the reliability for predicted events. It has been recently proposed that the reliability of an event can be estimated via its frequency in the set of most parsimonious reconciliations obtained using a variety of reasonable input cost vectors. To compute such a support, a straightforward but time-consuming approach is to generate the costs slightly departing from the original ones, independently compute the set of all most parsimonious reconciliations for each vector, and combine these sets a posteriori. Another proposed approach uses Pareto-optimality to partition cost values into regions which induce reconciliations with the same number of DTL events. The support of an event is then defined as its frequency in the set of regions. However, often, the number of regions is not large enough to provide reliable supports. We present here a method to compute efficiently event supports via a polynomial-sized graph, which can represent all reconciliations for several different costs. Moreover, two methods are proposed to take into account alternative input costs: either explicitly providing an input cost range or allowing a tolerance for the over cost of a reconciliation. Our methods are faster than the region based method, substantially faster than the sampling-costs approach, and have a higher event-prediction accuracy on

    2014-10-01

    Full Text Available This article briefly discusses some efforts that Rwanda has made to recover from the genocide, ranging from trying perpetrators to creating just social arrangements. It also discusses problematic policies and practices that may interfere with reconciliation. It then describes work the author and his associates have engaged in to promote healing and reconciliation in Rwanda. First, they conducted training/workshops to help people understand the influences that lead to genocide and other great violence, and avenues to prevention, healing and reconciliation. Following this they created educational radio programs for the same ends. The article describes a highly popular radio drama in Rwanda, which has been broadcast since 2004. Evaluation studies of both the effects of the trainings and of the radio drama have found positive effects that are highly relevant for reconciliation. These include more positive attitudes toward the other group, more empathy, more willingness to say what one believes, and more moderate respect for authority (presumably leading to less blind obedience. Anecdotal reports from the community also show the positive effects of the radio drama.

    Valdetaro, Eduardo Damianik; Schirru, Roberto

    2009-01-01

    Mass and energy balance are important issues that needs to keep into account in nuclear power plants. Data Reconciliation and Parameter Estimation (DRPE) and gross errors detection are techniques of increasing interest. Works using Genetic Algorithm (GA) have been successfully used in the Data Reconciliation (DR) nonlinear optimization problem, and it seems that evolutionary algorithms performs well without the complex calculations used by the conventional methods. The aim of this paper is to present the Particle Swarm Optimization Algorithm (PSO) as an alternative to the use of modified GA, which was applied to data reconciliation with simultaneous gross errors detection. In this paper, the DR formulation uses a redescending estimator as objective function and simulation results show that PSO applied to DRPE problem is faster than modified GA presented in literature, do not involve complex calculations and do not need complex parameters to adjust. The PSO algorithm is also able to handle the non-differentiable characteristics of the redescending estimator. (author)

    To investigate the impact of the introduction of an electronic medication management system on the proportion of patients with a recorded medication reconciliation on admission, the time from admission to when medication reconciliation was performed, and the characteristics of patients receiving this intervention pre-and post-implementation. An electronic medication management system was implemented in an Australian hospital from May to July 2015. A retrospective observational study was conducted in three wards across two phases; pre- (August 2014) and post- (August 2015) implementation. The study sample included every second patient admitted to these wards. A total of 370 patients were included, 179 pre- and 191 post-implementation. The proportion of recorded admission medication reconciliation significantly increased post-implementation in all study wards; coronary care unit (40 vs 68%, p=0.004), gastroenterology ward (39 vs 59%, p=0.015), and the neurology ward (19 vs 45%, p=0.002). The proportion of patients with recorded medication reconciliation within 24h of weekday admissions, or 48-72h of weekend admissions, increased from 47% pre- to 84% post-implementation. Admission medication reconciliation was recorded within a median of 1.0day for weekday admissions pre- and post-implementation (IQR 1.1 vs 0.2, respectively), and 3.5days (IQR 2.0) pre-implementation vs 1.5days (IQR 2.0) post-implementation for weekend admissions. Overall, across both phases pre-and post-implementation, admission medication reconciliation was recorded for patients who were significantly older (median 77 and 71 years, p<0.001), had a higher number of preadmission medications (median 6.5 and 5.0 medicines, p=0.001), and had a longer hospital stay (median 6.5 and 5.1days, p=0.003). A significantly higher proportion of patients with recorded medication reconciliation in the pre-implementation phase experienced polypharmacy (61%, p=0.002), hyperpolypharmacy (15%, p=0.001), and used a high

    Full Text Available The case of former Yugoslavia and its successors is specific and a bit different from the other post-conflict societies. First, retributive model of justice is carried out, or it should be carried out, before the International Criminal Tribunal in the Hague. The question is how to start the process of searching for the truth and reconciliation inside and between societies, groups and individuals in newly established countries. There is no such a model in the world, like these in South Africa and some countries in Latin America, which can be applied here, because in this case we are talking about five states, from which at least three were in the war. Also, the character of these conflicts covers the diapason from international conflicts to internal aggression and civil war.

  12. Religiosity and readiness for reconciliation: An anthropological view

    Directory of Open Access Journals (Sweden)

    Šantek Goran Pavel

    2015-01-01

    Full Text Available This paper is an anthropological study of processes that lead to the traumatization of a society, and of processes that result in forgiveness and reconciliation as chosen ways of dealing with post-conflict situations. The area on which the research is focused is Southeastern Europe, or more precisely Croatian and Serbian societies and relations. As cultural anthropology has not developed any special theory to deal with the causes of traumatic experiences in cultures and societies, this study uses the conceptions of closely related cultural sociology, formulated in Jeffrey Alexander's works. According to Alexander cultural trauma occurs when members of a collectivity feel they have been subjected to a horrendous event that leaves indelible marks upon their group consciousness, marking their memories forever and changing their future identity in fundamental and irrevocable ways. Insofar as they identify the cause of trauma, and thereby assume such moral responsibility, members of collectivities define their solidary relationships in ways that allow them to share the sufferings of others. In thinking that the suffering of others might also be our own societies expand the circle of the we. According to the same theory, when social groups refuse to recognize the existence of others' trauma and suffering, they not only diffuse their own responsibility for the suffering but often project the responsibility for their own suffering on these others. It is necessary then, for any process of reconciliation to be successful, that groups recognize suffering of others and their own responsibility. From the fact that social groups might refuse to participate in the process of trauma creation, it is obvious that trauma does not exist naturally, but that trauma is a social construction, a socially mediated attribution. This paper and research are also designed as an anthropological comparison with a huge sociological research of religiosity in Croatia done in

    AIMS: Movement into or out of hospital is a vulnerable period for medication safety. Reconciling the medication a patient is using before admission with the medication prescribed on discharge, and documenting any changes (medication reconciliation) is recommended to improve safety. The aims of the study were to investigate the factors contributing to medication reconciliation on discharge, and identify the prevalence of non-reconciliation. METHODS: The study was a cross-sectional, observational survey using consecutive discharges from purposively selected services in two acute public hospitals in Ireland. Medication reconciliation, potential for harm and unplanned re-admission were investigated. RESULTS: Medication non-reconciliation was identified in 50% of 1245 inpatient episodes, involving 16% of 9569 medications. The majority of non-reconciled episodes had potential to result in moderate (63%) or severe (2%) harm. Handwritten rather than computerized discharges (adjusted odds ratio (adjusted OR) 1.60, 95% CI 1.11, 2.99), increasing number of medications (adjusted OR 1.26, 95% CI 1.21, 1.31) or chronic illness (adjusted OR 2.08, 95% CI 1.33, 3.24) were associated with non-reconciliation. Omission of endocrine, central nervous system and nutrition and blood drugs was more likely on discharge, whilst omission on admission and throughout inpatient care, without documentation, was more likely for obstetric, gynaecology and urinary tract (OGU) or respiratory drugs. Documentation in the discharge communication that medication was intentionally stopped during inpatient care was less likely for cardiovascular, musculoskeletal and OGU drugs. Errors involving the dose were most likely for respiratory drugs. CONCLUSIONS: The findings inform strategies to facilitate medication reconciliation on discharge from acute hospital care.

  16. Towards a collaborative filtering approach to medication reconciliation.

    2008-11-06

    A physicians prescribing decisions depend on knowledge of the patients medication list. This knowledge is often incomplete, and errors or omissions could result in adverse outcomes. To address this problem, the Joint Commission recommends medication reconciliation for creating a more accurate list of a patients medications. In this paper, we develop techniques for automatic detection of omissions in medication lists, identifying drugs that the patient may be taking but are not on the patients medication list. Our key insight is that this problem is analogous to the collaborative filtering framework increasingly used by online retailers to recommend relevant products to customers. The collaborative filtering approach enables a variety of solution techniques, including nearest neighbor and co-occurrence approaches. We evaluate the effectiveness of these approaches using medication data from a long-term care center in the Eastern US. Preliminary results suggest that this framework may become a valuable tool for medication reconciliation.

    Full Text Available The Australian Government, referring to thousands of Abo-riginal children allegedly stolen from their parents, responded that "the Commonwealth does not seek to defend or justify past policies and practices, but it does assert that the sature and intent of those events have been misrepresented, and that the treatment of separated Aboriginal children was essentially lawful and benign in intent..." In 1998 the Chilean government opposed the proposed trial of Gen-eral Pinochet in Spain, protesting at the grave damage it would cause to the process of democratic transition and national reconciliation. The Government of Chile believes that whatever are the intentions of those promoting the process, this does not help the intended reconcili-ation — on the contrary, they will deepen for many years the differ-ences which exist between Chileans. Are national reconciliation and oral history compatible?

  1. Does Identification With Rwanda Increase Reconciliation Sentiments Between Genocide Survivors and Non-Victims? The Mediating Roles of Perceived Intergroup Similarity and Self-Esteem During Commemorations

    Directory of Open Access Journals (Sweden)

    Clémentine Kanazayire

    2014-12-01

    Full Text Available A questionnaire survey (N = 247 investigated the influence of identification with the Rwandan nation on reconciliation sentiments between members of the survivor and of the non-victim groups of the 1994 genocide in Rwanda. Results showed that, whereas the two groups did not differ in their level of identification with the nation, members of the non-victim group were more willing to reconcile than members of the survivor group. Perceived intergroup similarity mediated the effect of national identification on reconciliation sentiment for both groups, but this effect was stronger among non-victims. Finally, self-esteem during commemorations also mediated this effect, but only among non-victims. We discuss the importance of people’s motivation to reconcile with out-group members in post-genocidal contexts in light of the common in-group identity model (Gaertner & Dovidio, 2000 as well as the needs-based model of intergroup reconciliation (Nadler & Schnabel, 2008.

  2. Data Reconciliation in the Steam-Turbine Cycle of a Boiling Water Reactor

    Sunde, Svein; Berg, Oivind; Dahlberg, Lennart; Fridqvist, Nils-Olof

    2003-01-01

    A mathematical model for a boiling water reactor steam-turbine cycle was assembled by means of a configurable, steady-state modeling tool TEMPO. The model was connected to live plant data and intermittently fitted to these by minimization of a weighted least-squares object function. The improvement in precision achieved by this reconciliation was assessed from quantities calculated from the model equations linearized around the minimum and from Monte Carlo simulations. It was found that the inclusion of the flow-passing characteristics of the turbines in the model equations significantly improved the precision as compared to simple mass and energy balances, whereas heat transfer calculations in feedwater heaters did not. Under the assumption of linear model equations, the quality of the fit can also be expressed as a goodness-of-fit Q. Typical values for Q were in the order of 0.9. For a validated model Q may be used as a fault detection indicator, and Q dropped to very low values in known cases of disagreement between the model and the plant state. The sensitivity of Q toward measurement faults is discussed in relation to redundancy. The results of the linearized theory and Monte Carlo simulations differed somewhat, and if a more accurate analysis is required, this is better based on the latter. In practical application of the presently employed techniques, however, assessment of uncertainties in raw data is an important prerequisite

    Full Text Available In the psychological framework, reconciliation is a socio-cultural process, which includes majority of the members of the society, who form new beliefs about former enemies, about their own society and relations between these two groups. This process is about changing the system of beliefs of the members of the society. Maybe the most important change in this ideology of conflict is about the certainty of absolute righteousness of our own aims, which is in contradiction with similar beliefs of the opposite side.

    To evaluate the impact of a pharmacy-technician centered medication reconciliation (PTMR) program by identifying and quantifying medication discrepancies and outcomes of pharmacist medication reconciliation recommendations. A retrospective chart review was performed on two-hundred patients admitted to the internal medicine teaching services at Cooper University Hospital in Camden, NJ. Patients were selected using a stratified systematic sample approach and were included if they received a pharmacy technician medication history and a pharmacist medication reconciliation at any point during their hospital admission. Pharmacist identified medication discrepancies were analyzed using descriptive statistics, bivariate analyses. Potential risk factors were identified using multivariate analyses, such as logistic regression and CART. The priority level of significance was set at 0.05. Three-hundred and sixty-five medication discrepancies were identified out of the 200 included patients. The four most common discrepancies were omission (64.7%), non-formulary omission (16.2%), dose discrepancy (10.1%), and frequency discrepancy (4.1%). Twenty-two percent of pharmacist recommendations were implemented by the prescriber within 72 hours. A PTMR program with dedicated pharmacy technicians and pharmacists identifies many medication discrepancies at admission and provides opportunities for pharmacist reconciliation recommendations.

  11. Dialogical inquiry as an instrument of the reconciliation of conflict in the hands of Christian leaders

    Directory of Open Access Journals (Sweden)

    C.J. Hugo

    2010-07-01

    Full Text Available The apartheid system caused deep rifts in South African society, and even following the dawn of democracy, society in South Africa continues to struggle with violence and conflict, ethnic differences, mass action and poverty. Christian leaders have an important part to play in conflict resolution. Conflict management in organisations incorporates negotiation as a means of conflict resolution. A number of approaches to conflict resolution contribute to this approach; these include forcing, avoiding, accommodating, compromising and collaborating. Christian leaders, however, favour reconciliation as a means of resolving conflict. A Christian approach to conflict resolution needs to take cognisance of the existential aspect of conflict. Examples of such approaches are those of Dreyer, who speaks of reconciliation as a dilemma for forgiveness, and Kistner, who explores the way in which the use of narratives rather than reallife stories in the Truth and Reconciliation Commission reduced the severity of trauma. The social construction of trauma in “Mamelodi” by Brigid Hess, which presents a shift from forgiveness to a journey taken along with the perpetrators, and the belief of Desmond Tutu in the healing brought about by the ubuntu philosophy, are evaluated here as being detrimental to reconciliation. Based on the examples cited, an approach to conflict resolution entailing a clear integration of the biblical approach to reconciliation and dialogical inquiry (DI is proposed as an appropriate intervention approach for Christian leaders. The present contribution is offered from within the discipline of Practical Theology, with a focus on Pastoral Counseling.

    To discuss the relationships between ontologies, terminologies and language in the context of Natural Language Processing (NLP) applications in order to show the negative consequences of confusing them. The viewpoints of the terminologist and (computational) linguist are developed separately, and then compared, leading to the presentation of reconciliation among these points of view, with consideration of the role of the ontologist. In order to encourage appropriate usage of terminologies, guidelines are presented advocating the simultaneous publication of pragmatic vocabularies supported by terminological material based on adequate ontological analysis. Ontologies, terminologies and natural languages each have their own purpose. Ontologies support machine understanding, natural languages support human communication, and terminologies should form the bridge between them. Therefore, future terminology standards should be based on sound ontology and do justice to the diversities in natural languages. Moreover, they should support local vocabularies, in order to be easily adaptable to local needs and practices.

  14. Improving your real-time data infrastructure using advanced data validation and reconciliation

    2008-07-01

    'Smart fields', 'e-fields', 'field of the future', 'digital oil fields' and 'field monitoring' are all names of real-time data infrastructures aimed at providing information for decision making. This paper discusses these new real-time data infrastructures that are being developed and deployed in oil and gas production and in particular the challenge of supplying these new systems with high quality data. In order for these infrastructures to be successful and provide efficient and successful performance management and optimization, they need to have access to high quality production data. Advanced Data Validation and Reconciliation is a technology that could meet this data quality challenge. It has been successfully deployed in many different industry sectors and more recently in oil and gas production. Advanced Data Validation and Reconciliation provides a coherent, accurate set of production data and basing these new infrastructures on validated and reconciled data brings a solution to the data quality challenge. There are numerous other benefits by applying advanced data validation and reconciliation in oil and gas production, such as uninterrupted well production, optimized valves opening and water or gas injection, backup values for traditional multiphase flow meters, and the avoidance of production upsets.

  15. The Worlds First Ever Cooling Tower Acceptance Test Using Process Data Reconciliation

    International Nuclear Information System (INIS)

    Magnus Langenstein; Jan Hansen-Schmidt

    2006-01-01

    The cooling capacity of cooling towers is influenced by multiple constructive and atmospheric parameters in a very complex way. This leads to strong variations of the measured cold-water temperature and causes unacceptable unreliability of conventional acceptance tests, which are based on single point measurements. In order to overcome this lack of accuracy a new approach to acceptance test based on process data reconciliation has been developed by BTB Jansky and applied at a nuclear power plant. This approach uses process data reconciliation according to VDI 2048 to evaluate datasets over a long period covering different operating conditions of the cooling tower. Data reconciliation is a statistical method to determine the true process parameters with a statistical probability of 95% by considering closed material-, mass-and energy balances. Datasets which are not suitable for the evaluation due to strong transient gradients are excluded beforehand, according to well-defined criteria. The reconciled cold-water temperature is then compared, within a wet bulb temperature range of 5 deg. C to 20 deg. C to the manufacturer's guaranteed temperature. Finally, if the average deviation between reconciled and guaranteed value over the evaluated period is below zero, the cooling tower guarantee is fulfilled. (authors)

    2012-06-01

    This study aims to explore the perceptions of general practitioners (GPs) from the state of Penang toward the feasibility of implementing the medication reconciliation program in Malaysia. A cross-sectional descriptive study using a validated, self-completed anonymous 18-item questionnaire was undertaken over a period of 2 months in 2010. The study was conducted in the state of Penang, Malaysia. A letter consisting of survey questionnaires and prepaid return envelope were mailed to 429 GPs identified from the Private Medical Practice Control Department Registry. A total of 86 responses were received with response rate of 20.1%. Majority (90.1%) of the respondents agreed that medication reconciliation can be a feasible strategy to improve medication safety, and 97.7% confirmed that having an accurate up-to-date list of the patient's previous medication will be useful in the rational prescribing process. However, about half (56.9%) of them felt that standardization of the medication reconciliation process in all clinics will be difficult to achieve. Three quarters (73.2%) of the respondents believed that the involvement of GPs alone is insufficient, and 74.5% agreed that this program should be expanded to community pharmacy setting. More than 90% of the respondents agreed upon the medication reconciliation card proposed by the researchers. General practitioners in Penang are generally in favor of the implementation of medication reconciliation program in their practice. Because medication reconciliation has been shown to reduce many medicine-related problems, it is thus worth considering the feasibility of nationwide implementation of such program.

    2015-10-01

    Full Text Available This article seeks to contribute to the process of reconciliation in South Africa. This is achieved by firstly exploring the meaning of ubuntu as a common culture or religion under a large percentage of South Africa’s people over the borders of language and other cultural values. In the second part of the article two concepts that play a major role in Christianity are explored, namely koinonia and diakonia. Again a large percentage of South Africans believe that the Bible is the Word of God in which the right way of living is described. A comparison is made between the core values of ubuntu and the way of living that emerges from the use of the two concepts of koinonia and diakonia in the New Testament. A way that can contribute to reconciliation is suggested from this comparison.

  2. An Observational Study to Evaluate the Usability and Intent to Adopt an Artificial Intelligence-Powered Medication Reconciliation Tool.

    2016-05-16

    Medication reconciliation (the process of creating an accurate list of all medications a patient is taking) is a widely practiced procedure to reduce medication errors. It is mandated by the Joint Commission and reimbursed by Medicare. Yet, in practice, medication reconciliation is often not effective owing to knowledge gaps in the team. A promising approach to improve medication reconciliation is to incorporate artificial intelligence (AI) decision support tools into the process to engage patients and bridge the knowledge gap. The aim of this study was to improve the accuracy and efficiency of medication reconciliation by engaging the patient, the nurse, and the physician as a team via an iPad tool. With assistance from the AI agent, the patient will review his or her own medication list from the electronic medical record (EMR) and annotate changes, before reviewing together with the physician and making decisions on the shared iPad screen. In this study, we developed iPad-based software tools, with AI decision support, to engage patients to "self-service" medication reconciliation and then share the annotated reconciled list with the physician. To evaluate the software tool's user interface and workflow, a small number of patients (10) in a primary care clinic were recruited, and they were observed through the whole process during a pilot study. The patients are surveyed for the tool's usability afterward. All patients were able to complete the medication reconciliation process correctly. Every patient found at least one error or other issues with their EMR medication lists. All of them reported that the tool was easy to use, and 8 of 10 patients reported that they will use the tool in the future. However, few patients interacted with the learning modules in the tool. The physician and nurses reported the tool to be easy-to-use, easy to integrate into existing workflow, and potentially time-saving. We have developed a promising tool for a new approach to

  4. Reconciliation of equipment flexibility effects on piping system dynamic response

    Geraets, L.H.

    1987-01-01

    Piping systems are connected to equipment; if the equipment cannot be considered as ''rigid'' relative to excitation frequencies, nozzle response spectra techniques, or equipment modeling techniques are used. If the equipment is considered rigid, a fixed anchor is assumed. However, occasionally after (seismic) dynamic analysis has been completed, tests or detailed equipment dynamic analyses demonstrate that the assumption of ''infinite stiff'' is questionable. This paper reviews several classes of equipment (pumps, vessels, reservoirs, heat exchangers), and the associated (piping stresses, support loads, equipment nozzle allowables). Significant divergences between design and ''as built'' results are shown (for heat exchangers in particular). The paper discusses the reconciliation process performed for a belgian PWR plant through the use of less conservative seismic damping data (Code Case N-411)

    Full Text Available The TRC re-enactment consultation18 afforded the opportunity to reflect on the leadership of religious leaders during the apartheid era, and in the years that followed. This chapter is particularly interested in the prophetic leadership provided by religious leaders during apartheid, and 20 years following the transition by engaging with some normative thoughts on prophetic dialogue. The findings on the leadership provided during the post-TRC are reflected upon in terms of reconciliation through the hermeneutical lens of the Belgian scholar Valarie Rosoux. Hereby, this chapter seeked to contribute to reconciliation and national unity in the current South African context with some strategic conclusions to ensure that the process of reconciliation becomes a priority for all faith communities across the nation.

  6. Response surface reconciliation method of bolted joints structure

    Directory of Open Access Journals (Sweden)

    Yunus Mohd Azmi

    2017-01-01

    Full Text Available Structural joining methods such as bolted joints are commonly used for the assembly of structural components due to their simplicity and easy maintenance. Understandably, the dynamic characteristic of bolted joined structure is mainly influenced by the properties of their joints such as preload on the bolts and joints stiffness which alter the measured dynamics response of the structure. Therefore, the need to include the local effect of the bolted joints into the numerical model of the bolted joined structure is vitally important in order to represent the model accurately. In this paper, a few types of connector elements that can be used to represent the bolted joints such as CBAR, CBEAM and CELAS have been investigated numerically and experimentally. The initial numerical results of these element connectors are compared with the experimental results in term of natural frequencies and mode shapes. The comparative evaluation of numerical and the experimental data are performed in order to provide some insights of inaccuracies in the numerical model due to invalid assumption in the numerical modelling such as geometry, material properties, and boundary conditions. The discrepancies between both results (numerical and experimental data are then corrected using the response surface reconciliation method (RSRM through which the finite element model is altered in order to provide closer agreement with the measured data so that it can be used for subsequence analysis.

    2017-11-01

    Full Text Available Testifying to the gap in fundamental research on positive intergroup outcomes, we investigated reconciliation attitudes in a non-violent intergroup context (i.e., the linguistic conflict in Belgium. By incorporating both important predictors of negative outgroup attitudes (i.e., individual differences in rigid cognitive styles and authoritarian ideologies, and important predictors of reconciliation (i.e., intergroup emotions, we aimed to contribute to a more comprehensive theoretical framework for the analysis of intergroup relations. We recruited one Flemish ('N' = 310 and one Walloon ('N' = 365 undergraduate students sample to test the proposed model. Structural equation analyses with maximum likelihood estimation were conducted using the Lavaan package. In both samples, similar patterns were found. More in particular, the need for cognitive closure appeared to be the basic predictor of right-wing attitudes (i.e., right-wing authoritarianism and social dominance orientation and essentialist thinking, which were then associated with less outgroup empathy and trust, and more outgroup anger. Furthermore, outgroup trust and empathy were positively related to reconciliation. Interestingly, some differences between the Flemish and Walloon sample were found, such as the direct effects of need for closure and social dominance orientation in the first sample, and the non-significant effects of essentialism in the latter sample. Considering the ongoing public and political debate about the linguistic conflict in Belgium, these findings shed a new light on how individual differences relate to specific outgroup emotions, and how these are associated with important intergroup outcomes in the face of intergroup conflict.

  9. Gene-Tree Reconciliation with MUL-Trees to Resolve Polyploidy Events.

    Science.gov (United States)

    Gregg, W C Thomas; Ather, S Hussain; Hahn, Matthew W

    2017-11-01

    Polyploidy can have a huge impact on the evolution of species, and it is a common occurrence, especially in plants. The two types of polyploids-autopolyploids and allopolyploids-differ in the level of divergence between the genes that are brought together in the new polyploid lineage. Because allopolyploids are formed via hybridization, the homoeologous copies of genes within them are at least as divergent as orthologs in the parental species that came together to form them. This means that common methods for estimating the parental lineages of allopolyploidy events are not accurate, and can lead to incorrect inferences about the number of gene duplications and losses. Here, we have adapted an algorithm for topology-based gene-tree reconciliation to work with multi-labeled trees (MUL-trees). By definition, MUL-trees have some tips with identical labels, which makes them a natural representation of the genomes of polyploids. Using this new reconciliation algorithm we can: accurately place allopolyploidy events on a phylogeny, identify the parental lineages that hybridized to form allopolyploids, distinguish between allo-, auto-, and (in most cases) no polyploidy, and correctly count the number of duplications and losses in a set of gene trees. We validate our method using gene trees simulated with and without polyploidy, and revisit the history of polyploidy in data from the clades including both baker's yeast and bread wheat. Our re-analysis of the yeast data confirms the allopolyploid origin and parental lineages previously identified for this group. The method presented here should find wide use in the growing number of genomes from species with a history of polyploidy.

  10. On the significance of saying “sorry” – politics of memory and Aboriginal Reconciliation in Australia

    Directory of Open Access Journals (Sweden)

    Isabelle Auguste

    2009-06-01

    Full Text Available 2007 marked the 40th anniversary of the 1967 Referendum. Back on May 27th 1967, more than 90% of Australian eligible voters said “yes’ to two changes of the Australian Constitution considered discriminatory to Aboriginal people. This event is often considered as the first stage of Reconciliation in Australia. 2007 also marked the 10th Anniversary of the release of the Bringing Them Home Report that highlighted the forced removal of Aboriginal children from their family as part of an assimilation policy. From 1997, the issue of an apology became a sine qua non condition to Reconciliation. It was an important element of the recommendations the Council for Aboriginal Reconciliation submitted to Parliament in 2000. But, Liberal Prime Minister John Howard, in office for more than ten years, refused to say the word “sorry” on the basis that Australians of today are not responsible for the actions of the past and that guilt is not hereditary. His focus was on what is called “practical reconciliation”. Some changes are now on the way as Labor leader, Kevin Rudd, who defeated him at the last federal election in November 24th 2007, has promised to make a formal apology to the stolen generation. Why is it important to say “sorry”? At a time of dramatic developments in Indigenous Affairs, this paper deals with the significance of an apology for Reconciliation in Australia.

    Full Text Available Including outpatient pharmacies in the medication reconciliation process upon hospital discharge is not commonly performed. This case highlights the consequences of a patient refilling a discontinued prescription for valproic acid (VPA. We present a 32-year old male found unresponsive after ingesting delayed release divalproex sodium. Cerebral edema was visualized on magnetic resonance imaging. Hemodialysis and levo-carnitine treatment led to improved mental status, and VPA was discontinued. The same patient presented with VPA overdose eight months later after he continued to fill an outdated prescription. This case highlights consequences of VPA toxicity; it also demonstrates an opportunity to improve patient safety and high-value care by collaborating with outpatient pharmacies in the medication reconciliation process upon hospital discharge.

  14. A comparative evaluation of genome assembly reconciliation tools.

    The majority of eukaryotic genomes are unfinished due to the algorithmic challenges of assembling them. A variety of assembly and scaffolding tools are available, but it is not always obvious which tool or parameters to use for a specific genome size and complexity. It is, therefore, common practice to produce multiple assemblies using different assemblers and parameters, then select the best one for public release. A more compelling approach would allow one to merge multiple assemblies with the intent of producing a higher quality consensus assembly, which is the objective of assembly reconciliation. Several assembly reconciliation tools have been proposed in the literature, but their strengths and weaknesses have never been compared on a common dataset. We fill this need with this work, in which we report on an extensive comparative evaluation of several tools. Specifically, we evaluate contiguity, correctness, coverage, and the duplication ratio of the merged assembly compared to the individual assemblies provided as input. None of the tools we tested consistently improved the quality of the input GAGE and synthetic assemblies. Our experiments show an increase in contiguity in the consensus assembly when the original assemblies already have high quality. In terms of correctness, the quality of the results depends on the specific tool, as well as on the quality and the ranking of the input assemblies. In general, the number of misassemblies ranges from being comparable to the best of the input assembly to being comparable to the worst of the input assembly.

    2015-03-01

    The primary objective was to evaluate time, number of interface actions, and accuracy on medication reconciliation tasks using a novel user interface (Twinlist, which lays out the medications in five columns based on similarity and uses animation to introduce the grouping - www.cs.umd.edu/hcil/sharp/twinlist) compared to a Control interface (where medications are presented side by side in two columns). A secondary objective was to assess participant agreement with statements regarding clarity and utility and to elicit comparisons. A 1 × 2 within-subjects experimental design was used with interface (Twinlist or Control) as an independent variable; time, number of clicks, scrolls, and errors were used as dependent variables. Participants were practicing medical providers with experience performing medication reconciliation but no experience with Twinlist. They reconciled two cases in each interface (in a counterbalanced order), then provided feedback on the design of the interface. Twenty medical providers participated in the study for a total of 80 trials. The trials using Twinlist were statistically significantly faster (18%), with fewer clicks (40%) and scrolls (60%). Serious errors were noted 12 and 31 times in Twinlist and Control trials, respectively. Trials using Twinlist were faster and more accurate. Subjectively, participants rated Twinlist more favorably than Control. They valued the novel layout of the drugs, but indicated that the included animation would be valuable for novices, but not necessarily for advanced users. Additional feedback from participants provides guidance for further development and clinical implementations. Cognitive support of medication reconciliation through interface design can significantly improve performance and safety. © The Author 2015.

    Community pharmacists play a vital part in reconciling medications for patients transitioning from hospital to community care, yet their roles have not been fully examined in the extant literature. The objectives of this study were to: 1) examine the barriers and facilitators community pharmacists face when reconciling medications for recently discharged patients; and 2) identify pharmacists' preferred content and modes of information transfer regarding updated medication information for recently discharged patients. Community pharmacists were purposively and conveniently sampled from the Wisconsin (U.S. state) pharmacist-based research network, Pharmacy Practice Enhancement and Action Research Link (PEARL Rx). Community pharmacists were interviewed face-to-face, and transcriptions from audio recordings were analyzed using directed content analysis. The Theory of Planned Behavior (TPB) guided the development of questions for the semi-structured interviews. Interviewed community pharmacists (N = 10) described the medication reconciliation process to be difficult and time-consuming for recently discharged patients. In the context of the TPB, more barriers than facilitators of reconciling medications were revealed. Themes were categorized as organizational and individual-level themes. Major organizational-level factors affecting the medication reconciliation process included: pharmacy resources, discharge communication, and hospital resources. Major individual-level factors affecting the medication reconciliation process included: pharmacists' perceived responsibility, relationships, patient perception of pharmacist, and patient characteristics. Interviewed pharmacists consistently responded that several pieces of information items would be helpful when reconciling medications for recently discharged patients, including the hospital medication discharge list and stop-orders for discontinued medications. The TPB was useful for identifying barriers and facilitators of

    2013-08-01

    This study aimed to examine the role of a pharmacy technician-centered medication reconciliation (PTMR) program in optimization of medication therapy in hospitalized patients with HIV/AIDS. A chart review was conducted for all inpatients that had a medication reconciliation performed by the PTMR program. Adult patients with HIV and antiretroviral therapy (ART) and/or the opportunistic infection (OI) prophylaxis listed on the medication reconciliation form were included. The primary objective is to describe the (1) number and types of medication errors and (2) the percentage of patients who received appropriate ART. The secondary objective is a comparison of the number of medication errors between standard mediation reconciliation and a pharmacy-led program. In the PTMR period, 55 admissions were evaluated. In all, 50% of the patients received appropriate ART. In 27of the 55 admissions, there were 49 combined ART and OI-related errors. The most common ART-related errors were drug-drug interactions. The incidence of ART-related medication errors that included drug-drug interactions and renal dosing adjustments were similar between the pre-PTMR and PTMR groups (P = .0868). Of the 49 errors in the PTMR group, 18 were intervened by a medication reconciliation pharmacist. A PTMR program has a positive impact on optimizing ART and OI prophylaxis in patients with HIV/AIDS.

    1994-11-01

    During the period beginning November 1991 and ending September 1992, a series of tests were conducted at Foster Wheeler Development Corporation in a fluidized-bed coal carbonizer to determine its performance characteristics. The carbonizer was operated for 533 hours in a jetting fluidized-bed configuration during which 36 set points (steady-state periods) were achieved. Extensive data were collected on the feed and product stream compositions, heating values, temperatures, and flow rates. With these data, elemental and energy balances were computed to evaluate and confirm accuracy of the data. The carbonizer data were not as self-consistent as could be desired (balance closure imperfection). A software package developed by Science Ventures, Inc., of California, called BALAID, was used to reconcile the carbonizer data; the details of the reconciliation have been given in Volume 1 of this report. The reconciled data for the carbonizer were rigorously analyzed, correlations were developed, and the model was updated accordingly. The model was then used in simulating each of the 36 steady-state periods achieved in the pilot plant. The details are given in this Volume one. This Volume 2 provides details of the carbonizer data reconciliation.

  1. Restoring relationship between former genocide perpetrators and survivors of genocide against Tutsi in Rwanda through reconciliation villages

    Directory of Open Access Journals (Sweden)

    Mafeza, F.

    2013-06-01

    Full Text Available Throughout the 20th century, genocide has claimed many lives across the world. In Rwanda, the Genocide against the Tutsi was perpetrated with unprecedented violence and took the lives of more than one million. In the aftermath of the genocide, the interpersonal relationships between genocide survivors and former genocide perpetrators as well as their respective family members was undermined. Through Prison Fellowship Rwanda, former genocide perpetrators and survivors of genocide were brought together in reconciliation villages as a way of restoring their relationships. Drawing on interviews and focus group discussion with members of five reconciliation villages, this study uses a qualitative approach to examine how these villages contribute to the restoration of relationship between conflicting parties in the aftermath of the genocide against the Tutsi in Rwanda. The findings indicate that living together in reconciliation village combined with economic joint activities provided a favorable space in which negative-dehumanizing attitudes were overcome, while positive-re-humanizing attitudes were fostered. Additionally, the village offered members an opportunity for communication, reduced prejudice and fear among them, and generated trust in the community.

    Full Text Available Gender Mainstreaming (GM was introduced by the European Union (EU in 1997, as a strategy to achieve gender equality in all policy areas. Yet, European countries greatly diverge in their progress of implementation. We investigate the role GM played in Romanian and German policies aimed at achieving work-family reconciliation, using concepts from feminist policy analysis. Our analysis shows that pre-existing policies and discourse, the economic situation, as well as the relationship with the EU have shaped and impeded the implementation process of GM in both countries. While Germany slowly moves towards more egalitarian policies, GM as label and strategy did not succeed. In Romania, GM has only impacted work and family reconciliation indirectly through EU legislation.

    Full Text Available Therapeutic interchange of a same class medication for an outpatient medication is a widespread practice during hospitalization in response to limited hospital formularies. However, therapeutic interchange may increase risk of medication errors. The objective was to characterize the prevalence and safety of therapeutic interchange.Secondary analysis of a transitions of care study. We included patients over age 64 admitted to a tertiary care hospital between 2009-2010 with heart failure, pneumonia, or acute coronary syndrome who were taking a medication in any of six commonly-interchanged classes on admission: proton pump inhibitors (PPIs, histamine H2-receptor antagonists (H2 blockers, hydroxymethylglutaryl CoA reductase inhibitors (statins, angiotensin-converting enzyme (ACE inhibitors, angiotensin receptor blockers (ARBs, and inhaled corticosteroids (ICS. There was limited electronic medication reconciliation support available. Main measures were presence and accuracy of therapeutic interchange during hospitalization, and rate of medication reconciliation errors on discharge. We examined charts of 303 patients taking 555 medications at time of admission in the six medication classes of interest. A total of 244 (44.0% of medications were therapeutically interchanged to an approved formulary drug at admission, affecting 64% of the study patients. Among the therapeutically interchanged drugs, we identified 78 (32.0% suspected medication conversion errors. The discharge medication reconciliation error rate was 11.5% among the 244 therapeutically interchanged medications, compared with 4.2% among the 311 unchanged medications (relative risk [RR] 2.75, 95% confidence interval [CI] 1.45-5.19.Therapeutic interchange was prevalent among hospitalized patients in this study and elevates the risk for potential medication errors during and after hospitalization.

  7. Tracer measurements compared to process data reconciliation in accordance with VDI 2048

    The feed water mass flow is the key measured variable used to determine the thermal reactor output in a nuclear power plant. Usually this parameter is recorded via venturi nozzles or orifice plates. The problem with both principles of measurement, however, is that an accuracy of below 1% cannot be reached. In the case of nuclear power plants and depending on the size of the plant, this corresponds to an electrical output of 4 MWel to 16 MWel. In order to make more accurate statements about the feed water amounts recirculated in the water-steam circuit, tracer measurements that offer an accuracy of up to 0.2% are used. A drawback of this method is that this measuring principle is suitable only for providing an instantaneous picture but does not provide continuous operating information about the feed water mass flow. Process data reconciliation based on VDI 2048 is a mathematical-statistic process that makes use of redundant process information. The uncertainty of reconciled feed water flow rates and the thermal reactor output calculated on this basis can be reduced to 0.4%. The overall process monitored continuously in this manner therefore provides hourly process information of a quality equal to that obtained with acceptance measurements. In the NPP Beznau both methods have been used in parallel to determine the feed water flow rates in 2004 (unit 1) and 2005 (unit 2). Comparison of the results shows that a high level of agreement is obtained between the results of the reconciliation and the results of the tracer measurements. For this reason it was decided that no future tracer measurements will be conducted anymore. A result of the findings of this comparison, a high level of acceptance of process data reconciliation based on VDI 2048 was achieved. (author)

    2008-12-01

    Fibrobacter succinogenes S85, a strictly anaerobic Gram-negative bacterium, was grown in continuous culture in a bioreactor at different dilution rates (0.02 to 0.092 h(-1)) on a fully synthetic culture medium with glucose as carbon source. Glucose and ammonium sulfate consumption, as well as biomass, succinate, acetate, formate, and carbohydrate production were regularly measured. The relevant biomass elemental compositions were established for each dilution rate. Robustness of the experimental information was checked by C and N mass balances estimation, which were satisfactory. A detailed overall stoichiometry analysis of the process, including all substrates and products of the culture, was proposed. Online and off-line parameters measured during the culture brought a large number of data which were weighted by their respective variance associated to the measured value. The material balance resulted in an overdetermined linear system of equations made of weighted relationships including experimental data, elemental balances (C, H, O, N, S, Na), and an additional constraint. The mass balances involved in stoichiometric equations were solved using data reconciliation and linear algebra methods to take into account error measurements. This methodology allowed to establish the overall stoichiometric equation for each dilution rate studied.

    It is important to recognize the distinction between risk assessment and its components which include risk analysis, perspectives study, and decision analysis. Divergence of opinion within the scientific community as well as the public at large is a characteristic of issues related to nuclear power. The divergent opinions can largely be characterized as either optimistic or pessimistic in nature. Reconciliation of divergent viewpoints presents some difficult challenges. It is doubtful that issues which have an emotional or philosophical basis can be resolved through technical efforts. Public education on the technical issues might prove helpful

    2012-10-08

    Background Medication reconciliation has been mandated by the Irish government at transfer of care. Research is needed to determine the contribution of clinical pharmacists to the process. Objective To describe the contribution of emergency department based clinical pharmacists to admission medication reconciliation in Ireland. Main Outcome Measure Frequency of clinical pharmacist\\'s activities. Setting Two public university teaching hospitals. Methodology Adults admitted via the accident and emergency department, from a non-acute setting, reporting the use of at least three regular prescription medications, were eligible for inclusion. Medication reconciliation was provided by clinical pharmacists to randomly-selected patients within 24-hours of admission. This process includes collecting a gold-standard pre-admission medication list, checking this against the admission prescription and communicating any changes. A discrepancy was defined as any difference between the gold-standard pre-admission medication list and the admission prescription. Discrepancies were communicated to the clinician in the patient\\'s healthcare record. Potentially harmful discrepancies were also communicated verbally. Pharmacist activities and unintentional discrepancies, both resolved and unresolved at 48-hours were measured. Unresolved discrepancies were confirmed verbally by the team as intentional or unintentional. A reliable and validated tool was used to assess clinical significance by medical consultants, clinical pharmacists, community pharmacists and general practitioners. Results In total, 134 patients, involving 1,556 medications, were included in the survey. Over 97 % of patients (involving 59 % of medications) experienced a medication change on admission. Over 90 % of patients (involving 29 % of medications) warranted clinical pharmacy input to determine whether such changes were intentional or unintentional. There were 447 interventions by the clinical pharmacist regarding

  11. Data reconciliation and optimal operation of a Catalytic naphtha reformer

    2008-10-01

    Full Text Available The naphtha reforming process converts low-octane gasoline blending components to high-octane components for use in high-performance gasoline fuels. The reformer also has an important function as the producer of hydrogen to the refinery hydrotreaters. A process model based on a unit model structure, is used for estimation of the process condition using data reconciliation. Measurements are classified as redundant or non redundant and the model variables are classified as observable, barely observable or unobservable. The computed uncertainty of the measured and unmeasured variables shows that even if a variable is observable it may have a very large uncertainty and may thereby be practically unobservable. The process condition at 21 data points, sampled from two years of operation, was reconciled and used to optimize the process operation. There are large seasonal variations in the reformer product price and two operational cases are studied. In case 1, the product price is high and throughput is maximized with respect to process and product quality constraints. In case 2, the product price is low and the throughput is minimized with respect to a low constraint on the hydrogen production. Based on the characteristics of the optimal operation, a "self optimizing" control structure is suggested for each of the two operational cases.

    Extracts of plastic packaging, manufacturing, and delivery systems (or their materials of construction) are analyzed by chromatographic methods to establish the system's extractables profile. The testing strategy consists of multiple orthogonal chromatographic methods, for example, gas and liquid chromatography with multiple detection strategies. Although this orthogonal testing strategy is comprehensive, it is not necessarily complete and members of the extractables profile can elude detection and/or accurate identification/quantification. Because the chromatographic methods rarely indicate that some extractables have been missed, another means of assessing the completeness of the profiling activity must be established. If the extracts are aqueous and contain no organic additives (e.g., pH buffers), then they can be analyzed for their total organic carbon content (TOC). Additionally, the TOC of an extract can be calculated based on the extractables revealed by the screening analyses. The measured and calculated TOC can be reconciled to establish the completeness and accuracy of the extractables profile. If the reconciliation is poor, then the profile is either incomplete or inaccurate and additional testing is needed to establish the complete and accurate profile. Ten test materials and components of systems were extracted and their extracts characterized for organic extractables using typical screening procedures. Measured and calculated TOC was reconciled to establish the completeness of the revealed extractables profile. When the TOC reconciliation was incomplete, the profiling was augmented with additional analytical testing to reveal the missing members of the organic extractables profile. This process is illustrated via two case studies involving aqueous extracts of sterile filters. Plastic materials and systems used to manufacture, contain, store, and deliver pharmaceutical products are extracted and the extracts analyzed to establish the materials' (or

    Full Text Available The concept of national reconciliation became policy strategies in political discourse in Zimbabwe and Namibia after independence and South Africa after democratisation. The objective was to avoid the civil war experienced in neighbouring Angola and Mozambique after independence. Current argument however is that reconciliation mainly harmonising relations between blacks and whites and between the new government and capital is not sufficient. It is argued that reconciliation should fundamentally extent to the formerly deprived black majority the right of access to natural resource and addresses their economic well being. Political processes and developments in these three countries also reveal that settlement compromises made at independence and new democratic dispensation predicated on liberal constitutions followed by neo-liberal economic policies are sources of enormous governance challenges facing the leadership of these countries today.

    It has frequently been argued that the post-apartheid Truth and Reconciliation Commission (TRC) was committed to restorative justice (RJ), and that RJ has deep historical roots in African indigenous cultures by virtue of its congruence both with ubuntu and with African indigenous justice systems......, when the South African Law Commission published an Issue Paper dealing with RJ. Furthermore, I show that neither the connection between RJ and ubuntu nor the connection between RJ and AIJS is as straightforward and unproblematic as often assumed....

    Several factors contribute to the potential for patient confusion regarding his or her medication regimen, including multiple names for a single drug and formulary variations when the patient receives medications from more than one pharmacy. A 68-year-old woman was discharged from the hospital on a HMG-CoA reductase inhibitor (statin) and resumed her home statin. Eleven days later she returned to the hospital with a diagnosis of severe rhabdomyolysis due to statin overdose. IMPLEMENTING SOLUTIONS: Miami Valley Hospital, Dayton, Ohio, implemented a reconciliation process and order form at admission and discharge to reduce the likelihood that this miscommunication would recur. Initial efforts were trialed on a 44-bed orthopedic unit, with spread of the initiative to the cardiac units and finally to the remaining 22 nursing units. The team successfully implemented initiation of the order sheet, yet audits indicated the need for improvement in reconciling the medications within 24 hours of admission and in reconciling the home medications at the point of discharge. Successful implementation of the order sheet to drive reconciliation takes communication, perseverance, and a multidisciplinary team approach.

    Full Text Available ABSTRACT: Reconciliation is beyond diplomatic rapprochement and consequently strategic partnership in its maxim. It is irrelevant to transaction costs; moreover, “independent from them” since it is normative-oriented. Literature of reconciliation contains some concepts which cannot be “appreciated”, literally, in diplomatic realm, such as forgiving and forgetting, having theological connotations. To the contrary, international relations literature generally accept that “primordial factors like ethnicity and religion had no part in rational explanations for the way the world works”(Fox and Sandler 2004: 9; and nobody appreciates any political decision that sacrifices national interest on the altar of virtue. This study aims at elaborating on the Turkish-Armenian Reconciliation Commission which Turkey and Armenia had formed in 2001 within the framework of the aforementioned arguments. Keywords: Reconciliation, TARC, Diaspora. ÖZ: Uzlaşma süreçleri diplomatik yakınlaşmalar ve en azamisinden stratejik ortaklıkların çok ötesindeki durumsallıkları ifade etmektedir. Normatif yönlü olduklarından diplomatik anlamda ilişki kurmanın beraberinde getirebileceği maliyetlerden tamamıyla bağımsızdırlar. Uzlaşma literatürü diplomatik platformda genel olarak önemsenmeyen, hatta ötesinde teolojik yönü bile bulunan bağışlamak ya da affetmek gibi kavramlara yer vermektedir. Bunun tersine uluslararası ilişkiler literatürüne bakıldığında etnisite ya da din gibi primordiyal faktörlerin dünyada işlerin nasıl yürüdüğüne dair akılcı açıklamalar içinde kendilerine pek yer bulamadıkları gözlemlenmektedir (Fox ve Sandler, 2004: 9.

    Full Text Available This review aimed to explore the initiatives, interventions, and experiments implemented by employing organizations and designed to support the work-life reconciliation at workplaces, and the effects of these actions on employees’ well-being at work. A systematic literature review was conducted on the basis of a search in PsycInfo, ERIC, and the ISI Web of Science database of Social Sciences between January 2000 and May 2015. Those studies were included in which either organizational or individual-level initiatives, interventions, or experiments were implemented by employers at workplaces in order to promote the work-life reconciliation of their employees. Work-life reconciliation was considered to encompass all life domains and all career stages from early to the end of working career. The content analysis of 11 studies showed that effective employer actions focused on working time, care arrangements, and training for supervisors and employees. Flexibility, in terms of both working time and other arrangements provided for employees, and support from supervisors decreased work-family conflict, improved physical health and job satisfaction, and also reduced the number of absence days and turnover intentions. Overall, very few intervention studies exist investigating the effects of employer-induced work-life initiatives. One should particularly note the conditions under which interventions are most successful, since many contextual and individual-level factors influence the effects of organizational initiatives on employee and organizational outcomes.

    Abstract Work-family reconciliation plays a crucial role in the well-being of employees, having impacts at the individual, social and organizational level. Studies concluded that poor work-life balance as one of the ten predictors of psychosocial risks at work. A family-friendly culture relates to how an organization values and allows the articulation of the various spheres of its workers’ life. We intended to determine the effect of different variables like the existence of services, the org...

    It can often be questioned how well you can rely on process measurements, as most processes in bio-fuelled power plants are changing conditions continuously, and then also the measured values will follow the process. Heat exchangers are fouled; sensors are drifting; the fuel quality is varying without your knowledge e.g. with respect to moisture and ash content etc. The goal with this project is to improve the quality assurance with respect to sensors as well as the process performance as such. This is done by using the physical knowledge we have on the process and which is transferred into a simulation model. This is used to correlate different sensor measurements to each other. This is called data-reconciliation and has earlier been tested (Varmeforsk 2003) for steady state conditions by using material balances. In this project we want to take the methodology a bit further by considering process dynamics as well and by following the deviation between model predictions for different sensors to the actual measurements. By doing this, faults can be detected earlier than otherwise and more information can be acquired from the process. Information achieved by the proposed method can primarily be utilized by process operators and process engineers at power plants and in e.g. pulp and paper industry. Minute sampled data from the process have been used from the process data base during a two week period. During this period the process has been operated relatively stable during some periods and with a significant change in the conditions during a 12 hour period when the capacity was reduced to approximately 60% of the normal maximum capacity. First a Modellica model was built and verified towards process data. In parallel a more advanced simulation model made in APROS with an interface made by Process Vision has been used. The deviation between the measured and simulated variables has been calculated for a number of variables. We can see a significant deviation between

    Full Text Available Data reconciliation (DR and gross error detection are two common tools used in industry to provide accurate and reliable data, which is useful to analyse plant performance and basis for troubleshooting. DR techniques improve the accuracy of measurements by using redundancies in material and energy balances. This provides reliable information that could help decision making regarding plant operation, which potentially leads to financial benefit. This paper presents the utilization of plant data to perform troubleshooting of ammonia reactor, in particular the profile of catalyst activity. Bad plant data are collected and then analysed using DR to produces reconciled data, which could be used to detect and identify the gross error measurements. The input data for DR and gross error detection were gathered from Aspen HYSYS V8.8 simulations by modelling the single-bed ammonia reactor. The result presents that bad plant data could define actual system condition such as gross error measurements in normal condition or catalyst activity problem. Both conditions are modelled by DR to indicate actual system condition using statistical analysis and to perform troubleshooting. Appropriate troubleshooting could save time and provide financial benefits by avoiding wrong accusation of system problem, specifically in ammonia reactor evaluated in this paper.

    Accurate accounting of controlled drug transactions by inpatient hospital pharmacies is a requirement in the United States under the Controlled Substances Act. At many hospitals, manual distribution of controlled substances from pharmacies is being replaced by automated dispensing cabinets (ADCs) at the point of care. Despite the promise of improved accountability, a high prevalence (15%) of controlled substance discrepancies between ADC records and anesthesia information management systems (AIMS) has been published, with a similar incidence (15.8%; 95% confidence interval [CI], 15.3% to 16.2%) noted at our institution. Most reconciliation errors are clerical. In this study, we describe a method to capture drug transactions in near real-time from our ADCs, compare them with documentation in our AIMS, and evaluate subsequent improvement in reconciliation accuracy. ADC-controlled substance transactions are transmitted to a hospital interface server, parsed, reformatted, and sent to a software script written in Perl. The script extracts the data and writes them to a SQL Server database. Concurrently, controlled drug totals for each patient having care are documented in the AIMS and compared with the balance of the ADC transactions (i.e., vending, transferring, wasting, and returning drug). Every minute, a reconciliation report is available to anesthesia providers over the hospital Intranet from AIMS workstations. The report lists all patients, the current provider, the balance of ADC transactions, the totals from the AIMS, the difference, and whether the case is still ongoing or had concluded. Accuracy and latency of the ADC transaction capture process were assessed via simulation and by comparison with pharmacy database records, maintained by the vendor on a central server located remotely from the hospital network. For assessment of reconciliation accuracy over time, data were collected from our AIMS from January 2012 to June 2013 (Baseline), July 2013 to April 2014

    Full Text Available In 2006, the Government of Canada announced the approval of a final Residential Schools Settlement Agreement with the collaboration of the four churches responsible (United, Anglican, Presbyterian, Catholic, the federal government and residential school survivors. Schedule "N" of the Agreement lists the mandate of the TRC; therein, the TRC states one of its goals as: (d to promote awareness and public education of Canadians about the system and its impacts. Can education - as the TRC hopes to engender - truly be transformative, renewing relationships and promoting healing in the process of forging these new relationships? The literature reviewed and the conferences attended highlighted that generating empathy maybe a necessary ingredient for the instigation of social change, but is insufficient. Transformation through education, or reconciliation through truth-telling, testimonial reading and responsible listening would mean claiming a genuine, supportive responsibility for the colonial past. Educational policy and media initiatives are fundamental to creating awareness, developing public interest and support of the TRC's recommendations. However, authors also stress the importance of critical pedagogy in the whole process of truth andreconciliation, and that real reconciliation would require confronting the racism that initiated these institutions and allowed for a decontextualization of their impacts.

    Adverse drug events (ADEs) are a major cause of morbidity and mortality, with more than 50% of ADEs being preventable. Adverse Drug Reactions (ADRs) are typically the result of an incomplete medication history, prescribing or dispensing error, as well as over- or under-use of prescribed pharmacotherapy. Medication reconciliation is the process of creating the most accurate list of medications a patient is taking and subsequently comparing the list against the different transitions of care. It is used to reduce medication discrepancies, and thereby ultimately decreasing ADEs. However, little is known about medicine reconciliation activities among public hospitals in South Africa. Prospective quantitative, descriptive design among Internal and Surgical wards in a leading public hospital in South Africa. 145 study participants were enrolled. Over 1300 (1329) medicines were reviewed of which there was a significant difference (p = 0.006) when comparing the medications that the patient was taking before or during hospitalisation. A total of 552 (41.53%) interventions were undertaken and the majority of patients had at least 3.96 medication discrepancies. The most common intervention upon admission was transcribing the home medication onto the hospital prescription (65.2%) followed by medication duplication (13.44%). During patient's hospital stay, interventions included patient counselling (32.5%) and stopping the previous treatment (37.5%). To ensure continuity of patient care, medication reconciliation should be implemented throughout patients' hospital stay. This involves all key professionals in hospitals.

  16. Ageing nuclear plants inspection, maintenance and performance monitoring eased by Data Validation and Reconciliation (DVR) approach

    2012-01-01

    With the long term operation of nuclear power plants, decisions to replace or repair should be optimized from an economical, human resource and safety point of view. In that frame, the operation requires a continuous inspection and testing of systems in order to detect degradations and failures at an early stage. Nevertheless, in spite of the fact that such assiduous vigilance ensures safety, it is not optimized in terms of man power and maintenance costs. Preventive strategies show the same types of drawbacks. On top of that, these maintenance procedures rely on process measurements which accuracy, availability and reliability cannot always be ensured. The present paper introduces a new approach to the maintenance management of ageing installations and suggests a method that overcomes the actual drawbacks. The Reconciliation and Validation of data (DVR) is an advanced and innovative technology that relies on process data statistics, thermodynamic and on-site process knowledge. Benefits of real-time applications are also presented. (author)

    2017-01-01

    We analyze the security of the two-way continuous-variable quantum key distribution protocol in reverse reconciliation against general two-mode attacks, which represent all accessible attacks at fixed channel parameters. Rather than against one specific attack model, the expression of secret key rates of the two-way protocol are derived against all accessible attack models. It is found that there is an optimal two-mode attack to minimize the performance of the protocol in terms of both secret key rates and maximal transmission distances. We identify the optimal two-mode attack, give the specific attack model of the optimal two-mode attack and show the performance of the two-way protocol against the optimal two-mode attack. Even under the optimal two-mode attack, the performances of two-way protocol are still better than the corresponding one-way protocol, which shows the advantage of making double use of the quantum channel and the potential of long-distance secure communication using a two-way protocol.

The cities’ demographic picture has been changed, as well as the ethnic and social structure. That is why we have been conducting our activities in the community reconciliation process in rural and urban areas, applying different methods of work. Our activities were aimed at all national and social groups. Our association’s target group is women. With our activities, we are trying to raise public awareness about the women’s issues and to find solutions to those problems. We have worked on key problems that arose as a consequence of war experiences, which were brought forward by the women. We are trying to achieve an insight into the problems that are common to the women from different social and ethnic groups and, by attempting to solve them; we work on conflict resolution and transformation.

    We studied intergroup responses as a function of relative intergroup status and familiarity. In Study 1, 34 African Americans and 34 European Americans interacted with two members of the out-group in separate, 20 minute dyadic interactions. Intergroup perception, affect, and behavior were asymmetric; Blacks differentiated the traits of and the quality of interactions with Whites, whereas Whites did not make these differentiations. Blacks and Whites predicted that different out-group partners perceived them similarly. Study 2 showed that the failure to differentiate an out-group member is due to intergroup status differences. Asymmetric intergroup responses pose a barrier to intergroup reconciliation and explain, in part, why increased interracial contact has not eradicated disparities in life outcomes for Black Americans.

    Full Text Available O artigo pretende explicitar a relação entre arte e reconciliação no pensamento de Herbert Marcuse, considerando-se vários de seus escritos que tocam no tema. Ao longo deles, percebe-se que o uso do termo reconciliação assume um duplo significado: por um lado, significa a possibilidade de que os temas sublimados da cultura possam ser efetivados no plano das relações materiais, o que implicaria o desaparecimento da arte; por outro, significa a imagem de um mundo harmonizado que a arte preserva em si e que se distancia da ordem social. Sob esse aspecto, a arte permanece utopia.This paper aims to clarify the relation between art and reconciliation in Herbert Marcuse's thought, according to some of his writings concerning the subject. These works employ the term "reconciliation" with two meanings: it means the possibility of effectuating within material relations the sublimed cultural themes and this would result in the disappearance of the art; on the other hand, it means the image of a harmonic world which art preserves in itself and that stays away from social order. Under this aspect, art remains utopia.

    To quantify and to classify the discrepancies between the admission treatment and the usual patient treatment. To determine the variables that predict those patients that will have more benefit from medication reconciliation. A prospective medication reconciliation study was conducted in the Vascular Surgery Unit from March 2014 to December 2014. When the patients were admitted to the Vascular Surgery Unit, they were informed about the study and asked to prepare information about their chronic treatment. The pharmacist then checked their clinical records, outpatient prescriptions, and also interviewed the patient, obtaining the best pharmacotherapeutic history available. The discrepancies with the admission treatment were written into the patient electronic clinical records. Finally, the physician classified the discrepancies, and changed the treatment, if needed. The statistical analysis included a comparison between patients with and without a non-justified discrepancy (NJD). The statistically different characteristics were used to plot Receiver Operating Characteristic curves, in order to determine the sensitivity and the specificity of these variables to select patients with discrepancies. A total of 380 patients were included. There were 845 non-justified, 600 justified non-documented, and 439 justified documented discrepancies. At least one NJD was identified in 293 patients (77%), with 65 patients (17%) having only justified discrepancies, and 22 patients (6%) having no discrepancies. NJD were: different dose, route or schedule (51%), omission (39%), wrong drug (8%) and commission (2%). The variables associated with discrepancies were number of chronic medications drugs and provider of information. In most studies, omission is the most frequent error. In contrast, in our study the most frequent error is different dose, route, or schedule. The variable that allows selecting patients at higher risk of discrepancies is the number of chronic drugs. This risk is

    Full Text Available In the modern legal system of the Republic of Kazakhstan development of the mechanism for reconciliation was worked out. The President of the Republic of Kazakhstan has repeatedly pointed out the need to implement progressive world experience of extrajudicial reconciliation. This is the idea of various forms of mediation introduction in the settlement of disputes enshrined in the Concept of Legal Policy of the Republic of Kazakhstan for the period from 2010 to 2020. At the same time there is the Law "On Mediation" of the year 2011 in the Republic of Kazakhstan, which has to create legal basis for the broad and civilized use of this procedure and to reduce the increasing burden on the courts. The analysis showed that the adoption of the Law "On Mediation" has not led to a decrease load on the courts; mediation is not widespread among the population and underdeveloped. It was also noted in the article, that in 2013, for example, the courts completed only 3% of civil cases by settlement. Authors conclude that for the serious crimes, firstly committed and not connected with the death or grievous bodily harm could be settled not only between minors, but also among other socially vulnerable people - pregnant women, mothers with dependent minor children, senior citizens. Authors note that the range of methods of conciliation is large enough. It develops, including all new mechanisms into the category of the means by which it is possible to resolve any conflict without recourse to the state Justice. Consequently, the expansion of pre-trial settlement of disputes, the introduction of a simplified form of consideration of claims would contribute to the further development of fast and affordable justice.

    A process model (PM) represents the graphical depiction of a business process, for instance, the entire process from online ordering a book until the parcel is delivered to the customer. Knowledge about relevant factors for creating PMs of high quality is lacking. The present study investigated the role of cognitive processes as well as modelling processes in creating a PM in experienced and inexperienced modellers. Specifically, two working memory (WM) functions (holding and processing of information and relational integration) and three process of process modelling phases (comprehension, modelling, and reconciliation) were related to PM quality. Our results show that the WM function of relational integration was positively related to PM quality in both modelling groups. The ratio of comprehension phases was negatively related to PM quality in inexperienced modellers and the ratio of reconciliation phases was positively related to PM quality in experienced modellers. Our research reveals central cognitive mechanisms in process modelling and has potential practical implications for the development of modelling software and teaching the craft of process modelling.

    Medication discrepancies are common when patients cross organisational boundaries. However, little is known about the frequency of discrepancies within mental health and the efficacy of interventions to reduce discrepancies. To evaluate the impact of a pharmacy-led reconciliation service on medication discrepancies on admissions to a secondary care mental health trust. In-patient mental health services. Prospective evaluation of pharmacy technician led medication reconciliation for admissions to a UK Mental Health NHS Trust. From March to June 2012 information on any unintentional discrepancies (dose, frequency and name of medication); patient demographics;and type and cause of the discrepancy was collected. The potential for harm was assessed based on two scenarios; the discrepancy was continued into primary care, and the discrepancy was corrected during admission. Logistic regression identified factors associated with discrepancies. Mean number of discrepancies per admission corrected by the pharmacy technician. Unintentional medication discrepancies occurred in 212 of 377 admissions (56.2 %). Discrepancies involving 569 medicines (mean 1.5 medicines per admission) were corrected.The most common discrepancy was omission(n = 464). Severity was assessed for 114 discrepancies. If the discrepancy was corrected within 16 days the potential harm was minor in 71 (62.3 %) cases and moderate in 43(37.7 %) cases whereas if the discrepancy was not corrected the potential harm was minor in 27 (23.7 %) cases and moderate in 87 (76.3 %) cases. Discrepancies were associated with both age and number of medications; the stronger association was age. Medication discrepancies are common within mental health services with potentially significant consequences for patients.Trained pharmacy technicians are able to reduce the frequency of discrepancies, improving safety.

    The 20th century was a century of genocide and other great violence between groups within societies. Already at the beginning of the 21st century, there have been mass killings, civil wars, violent conflict, and terrorism. This article summarizes influences that tend to lead to intense group violence. It then considers prevention, stressing early prevention--and reconciliation as an aspect of prevention--and focusing on central principles and practices. The principles include developing positive orientations to previously devalued groups; healing from past victimization and promoting altruism born of suffering; moderating respect for authority; creating constructive ideologies; promoting understanding of the origins of violence, its impact, and avenues to prevention; promoting truth, justice, and a shared history; and raising inclusively caring, morally courageous children. Practices related to all of these are also discussed. The article stresses the role of progressive change, that is, of psychological, behavioral, and social evolution, in both extreme violence and positive relations between groups; the role of passive bystanders in the unfolding of violence; and the role of active bystandership in the prevention of violence, in the promotion of reconciliation, and in the development of harmonious societies. It emphasizes psychological processes but notes the importance of creating societal institutions. The author cites findings from both laboratory research and case studies, reviews interventions and their evaluation in Rwanda, and points to the need for further research.

    Effort was dedicated to development and testing of a formal strategy for reconciling uncertain test data with physically limited computational prediction. Specific weaknesses in the logical structure of the current Power Balance Model (PBM) version are described with emphasis given to the main routing subroutines BAL and DATRED. Selected results from a variational analysis of PBM predictions are compared to Technology Test Bed (TTB) variational study results to assess PBM predictive capability. The motivation for systematic integration of uncertain test data with computational predictions based on limited physical models is provided. The theoretical foundation for the reconciliation strategy developed in this effort is presented, and results of a reconciliation analysis of the Space Shuttle Main Engine (SSME) high pressure fuel side turbopump subsystem are examined.

    Full Text Available An ecclesiological model for the ministry of reconciliation in a socio-political context This research article examines an ecclesiological model suitable for the promotion of socio-political reconciliation in the South African context from a reformed theological and philo-sophical pespective. Its point of departure is that reformational theology is per definition a public theology, which is inter alia directed at the renewal of society, and that churches have a positive role to play in this regard. Firstly, the article investigates the historic contribution of Kuyper’s ecclesiology and Dooye-weerd’s perspective on social life and the philosophy of the Idea of Law. Secondly, the article focuses on the biblical concept “Kingdom of God” and its implications for an ecclesiological model. Taking into account the contributions of these two lines of thought, the article concludes that the church should be seen as the “power station” of society. The church should equip believers to promote socio-political transformation in society. Furthermore, the church should be actively engaged in socio-political transformation by preaching the reconciliation in Christ and its implications for society, and by being an example of reconciliation amidst a divided community by overcoming the divisions caused by racism, tribalism, sexism, xenophobia, homophobia and ethnocentrism in its own midst.

    2015-07-01

    Full Text Available As emphasized in a study published last year, when multiple legal orders and languages co-exist within a single legal regime, there is potential for divergences between the legal texts. The European Union gives rise to such divergences, having in mind that it integrates 28 Member States and 24 official languages. After discovering how the multilingual and multicultural environment of the European Union affects its legislative and judicial processes and arguing the problem of translation divergences between the authentic texts of the European Union, it is nowadays our concern to analyse the reconciliation of language versions with diverging meanings in the EU legal order. The present study is part of a more complex research on this theme and it is meant to approach certain important points of the master thesis prepared in Switzerland for a LL.M. program.

    To study the frequency of medication reconciliation errors (MREs) in hospitalized patients and explore the profiles of patients at greater risk. To compare the rates of errors in prescriptions written by emergency physicians and ward physicians, who each used a different prescribing tool. Prospective cross-sectional study of a convenience sample of patients admitted to medical, geriatric, and oncology wards over a period of 6 months. A pharmacist undertook the medication reconciliation report, and data were analyzed for possible associations with risk factors or prescriber type (emergency vs ward physician). A total of 148 patients were studied. Emergency physicians had prescribed for 68 (45.9%) and ward physicians for 80 (54.1%). A total of 303 MREs were detected; 113 (76.4%) patients had at least 1 error. No statistically significant differences were found between prescriber types. Factors that conferred risk for a medication error were use polypharmacy (odds ratio [OR], 3.4; 95% CI, 1.2-9.0; P=.016) and multiple chronic conditions in patients under the age of 80 years (OR, 3.9; 95% CI, 1.1-14.7; P=.039). The incidence of MREs is high regardless of whether the prescriber is an emergency or ward physician. The patients who are most at risk are those taking several medications and those under the age of 80 years who have multiple chronic conditions.

    A process model (PM) represents the graphical depiction of a business process, for instance, the entire process from online ordering a book until the parcel is delivered to the customer. Knowledge about relevant factors for creating PMs of high quality is lacking. The present study investigated the role of cognitive processes as well as modelling processes in creating a PM in experienced and inexperienced modellers. Specifically, two working memory (WM) functions (holding and processing of information and relational integration) and three process of process modelling phases (comprehension, modelling, and reconciliation) were related to PM quality. Our results show that the WM function of relational integration was positively related to PM quality in both modelling groups. The ratio of comprehension phases was negatively related to PM quality in inexperienced modellers and the ratio of reconciliation phases was positively related to PM quality in experienced modellers. Our research reveals central cognitive mechanisms in process modelling and has potential practical implications for the development of modelling software and teaching the craft of process modelling.

    2012-09-15

    Gene duplication (D), transfer (T), loss (L) and incomplete lineage sorting (I) are crucial to the evolution of gene families and the emergence of novel functions. The history of these events can be inferred via comparison of gene and species trees, a process called reconciliation, yet current reconciliation algorithms model only a subset of these evolutionary processes. We present an algorithm to reconcile a binary gene tree with a nonbinary species tree under a DTLI parsimony criterion. This is the first reconciliation algorithm to capture all four evolutionary processes driving tree incongruence and the first to reconcile non-binary species trees with a transfer model. Our algorithm infers all optimal solutions and reports complete, temporally feasible event histories, giving the gene and species lineages in which each event occurred. It is fixed-parameter tractable, with polytime complexity when the maximum species outdegree is fixed. Application of our algorithms to prokaryotic and eukaryotic data show that use of an incomplete event model has substantial impact on the events inferred and resulting biological conclusions. Our algorithms have been implemented in Notung, a freely available phylogenetic reconciliation software package, available at http://www.cs.cmu.edu/~durand/Notung. mstolzer@andrew.cmu.edu.

  18. Policy reconciliation for access control in dynamic cross-enterprise collaborations

    2018-03-01

    In dynamic cross-enterprise collaborations, different enterprises form a - possibly temporary - business relationship. To integrate their business processes, enterprises may need to grant each other limited access to their information systems. Authentication and authorization are key to secure information handling. However, access control policies often rely on non-standardized attributes to describe the roles and permissions of their employees which convolutes cross-organizational authorization when business relationships evolve quickly. Our framework addresses the managerial overhead of continuous updates to access control policies for enterprise information systems to accommodate disparate attribute usage. By inferring attribute relationships, our framework facilitates attribute and policy reconciliation, and automatically aligns dynamic entitlements during the evaluation of authorization decisions. We validate our framework with a Industry 4.0 motivating scenario on networked production where such dynamic cross-enterprise collaborations are quintessential. The evaluation reveals the capabilities and performance of our framework, and illustrates the feasibility of liberating the security administrator from manually provisioning and aligning attributes, and verifying the consistency of access control policies for cross-enterprise collaborations.

  19. An other-typological illustration of the Exodus story according to Dr King’s perception of universal reconciliation in his sermon on Exodus 14:30

    2016-11-01

    Full Text Available The article contends that Dr King makes an other-typological illustrative use of the Exodus story in his preaching – one of the most significant biblical narratives that the Black church in the US holds dear. This peculiar use of the Exodus story differentiates itself from the conventional typological understanding and use of the same story in the Black church’s history. While in the latter the Exodus story has a symbolic meaning of the irreconcilable conflict between the oppressed and the oppressing reality, in the former the same story contains a spiritual lesson that what is really hoped for in the midst of the seemingly irreconcilable racial and social conflict is compassion, liberation, and reconciliation for both parties involved. This article, by examining a representative sermon of Dr King on the Exodus story, shows that his other-typological illustrative approach originates from his fundamental theological ideal of universal reconciliation.

    2011-01-01

    Operational decisions related to plant performance monitoring mainly result from raw process measurement analysis. When first signs of sub-optimal behavior occur, traditional methods mainly focus on the observation of selective pieces of information. The main disadvantages of these methods are: Investigation efforts are required to localize the problems, entailing time losses and costs; Validity and reliability of the pieces of information cannot be checked as long as the measurements are observed individually. The problem is not the lack of methods and techniques but rather a lack of reliable and consistent data and information across the entire plant. To overcome drawbacks of traditional methods, measurements are considered as interacting with one another. When related to the other measurements of the plant, the observed information becomes of an interest: its incoherency to the others identifies and localizes a problem. The Data Validation and Reconciliation technology (DVR) is based on an advanced process data coherency treatment. By using all available plant information and by closing the plant heat and mass balances based on rigorous thermodynamics, the method generates: A single set of reliable and most accurate plant process data; Alarms for incoherent measurements, highlighting potential problems; Alarms for equipment and process performance degradation; Alarms for faulty and drifting measurements. The use of the advanced DVR software package VALI offers various benefits as it allows to base operational decisions on reliable and accurate data. (author)

    Objectives To improve treatment of patients with depression, a new pilot service project involving student pharmacists who would conduct medication reconciliation and review of antidepressant treatment history was created and evaluated. Experimental design A prospective study conducted at the University of Michigan Depression Center. Principal observations From an initial sample of 78 referrals, 41 subjects were reached by phone, with 34 completing medication reconciliation and antidepressant treatment history. Of the 34 patients, 25 (73.5%) had at least one discrepancy identified in their medication list, resulting in 164 medication changes in the electronic medical record (EMR). A total of 105 past antidepressant trials were documented in the 34 individuals, with 34 (32.4%) trials found to be inadequate. Thirteen (38.2%) patients reported failure to respond to two different antidepressants from different classes. All 34 patients participated well in the phone calls and were willing to consult a pharmacist at their upcoming clinic visit. Conclusions A student pharmacist pilot was feasible, identified many discrepancies in the medication record, and identified important medication treatment history in patients with depression in advance of the clinic visit. The project provides support for a specialized role for student pharmacists and demonstrates that interprofessional care can contribute to improved treatment of depression. PMID:28626270

  3. Tracer test method and process data reconciliation based on VDI 2048. Comparison of two methods for highly accurate determination of feedwater massflow at NPP Beznau

    Hungerbuehler, T.; Langenstein, M.

    2007-01-01

    The feedwater mass flow is the key measured variable used to determine the thermal reactor output in a nuclear power plant. Usually this parameter is recorded via venturi nozzles of orifice plates. The problem with both principles of measurement, however, is that an accuracy of below 1% cannot be reached. In order to make more accurate statements about the feedwater amounts recirculated in the water-steam cycle, tracer measurements that offer an accuracy of up to 0.2% are used. In the NPP Beznau both methods have been used in parallel to determine the feedwater flow rates in 2004 (unit 1) and 2005 (unit 2). Comparison of the results shows that a high level of agreement is obtained between the results of the reconciliation and the results of the tracer measurements. As a result of the findings of this comparison, a high level of acceptance of process data reconciliation based on VDI 2048 was achieved. (orig.)

  4. Continuous Material Balance Reconciliation for a Modern Plutonium Processing Facility

    International Nuclear Information System (INIS)

    CLARK, THOMASG.

    2004-01-01

    This paper describes a safeguards approach that can be deployed at any modern plutonium processing facility to increase the level of safeguards assurance and significantly reduce the impact of safeguards on process operations. One of the most perplexing problems facing the designers of plutonium processing facilities is the constraint placed upon the limit of error of the inventory difference (LEID). The current DOE manual constrains the LEID for Category I and II material balance areas to 2 per cent of active inventory up to a Category II quantity of the material being processed. For 239Pu a Category II quantity is two kilograms. Due to the large material throughput anticipated for some of the modern plutonium facilities, the required LEID cannot be achieved reliably during a nominal two month inventory period, even by using state-of-the-science non-destructive assay (NDA) methods. The most cost-effective and least disruptive solution appears to be increasing the frequency of material balance closure and thus reducing the throughput being measured during each inventory period. Current inventory accounting practices and systems can already provide the book inventory values at any point in time. However, closing the material balance with measured values has typically required the process to be cleaned out, and in-process materials packaged and measured. This process requires one to two weeks of facility down time every two months for each inventory, thus significantly reducing productivity. To provide a solution to this problem, a non-traditional approach is proposed that will include using in-line instruments to provide measurement of the process materials on a near real-time basis. A new software component will be developed that will operate with the standard LANMAS application to provide the running material balance reconciliation, including the calculation of the inventory difference and variance propagation. The combined measurement system and software

    Full Text Available This article draws on a well-known narration of the Gugulethu Seven incident from the Truth and Reconciliation Commission (TRC proceedings with specific reference to testimonies of the mothers of the Gugulethu Seven. The article focuses on Mrs Konile’s testimony as a case study: Testimony of a black woman whose son was murdered by the apartheid government’s security forces. During the TRC hearings, Mrs Konile ‘failed’ to effectively narrate her story, which resulted in her testimony being dismissed as being incoherent. This article examines the underlying attributes of Mrs Konile’s testimony and revisits why she was considered ‘incapable’ of articulating her experience in a convincing manner. The analysis aims to acknowledge, identify and give insights about this woman’s testimony from an African women theologian viewpoint (specifically with references to the Isixhosa religious cultural background.

    currently, the mainstream Western views on world order mainly include hegemony order theory, balance of power theory, world system theory, the clash of civilizations theory, and democratic peace theory. These five theories are based on conflicting order of the evil human nature assumption. After the end of the cold war, the trends of power multi-polarization, economic globalization, political democratization, social networking, and global-wide risks have increasingly become challenges to the concept of conflicting order. In this context, the significance of a harmonious order based on China traditional views has emerged. The concept of a harmonious order based on kind human nature assumption tries to discover and promote the human moral elements. In the view of harmonious order, the world order is a harmonious state of coexisting multi-actors, the relationship between main actors is friendly relationship, and the interaction between actors is mainly in the form of mutual aid and courtesy. The western frontier theoretical progress, for example, constructivism, feminism, global governance, and international ethics studies basically fit into the harmonious order logic. Simultaneously, the advantage of the harmonious order concept is reflected in its logical similarity to and its strong applicability of an "integrated order", etc. Global governance is a kind of reconciliation idea, which is based on the harmonious order concept, and its basic logic is "weak conflict logic plus strong harmony logic",the basic framework is to establish a world-wide authoritative coordination, with country-to-country relations structure emphasizing friendship from interests, seeking common ground while reserving differences, and being multi-actors deliberative democracy in the form of interaction.

    Cloud computing refers to subscription-based, fee-for-service utilization of computer hardware and software over the Internet. The model is gaining acceptance for business information technology (IT) applications because it allows capacity and functionality to increase on the fly without major investment in infrastructure, personnel or licensing fees. Large IT investments can be converted to a series of smaller operating expenses. Cloud architectures could potentially be superior to traditional electronic health record (EHR) designs in terms of economy, efficiency and utility. A central issue for EHR developers in the US is that these systems are constrained by federal regulatory legislation and oversight. These laws focus on security and privacy, which are well-recognized challenges for cloud computing systems in general. EHRs built with the cloud computing model can achieve acceptable privacy and security through business associate contracts with cloud providers that specify compliance requirements, performance metrics and liability sharing.

    Full Text Available Over the last few years, I have attended several political meetings concerned with the refugee crisis, multiculturalism or Indigenous rights in Australia, meetings at which liberal democratic–minded ‘left-wing’ people came together to discuss, or agitate for change in, governmental policies. At these meetings, I always found it difficult to accept the slogans on their placards and in their speeches: ‘Shame Australia! Reconciliation for a united Australia’, ‘Wake up Australia! We welcome refugees!’ or ‘True Australians are tolerant! Let’s celebrate multicultural Australia!’ My uncomfortable feeling came not only from the fact that I was left out because of my Japanese nationality but also because I had never seen or heard words like ‘shame Japan’, ‘wake up Japan’ or ‘true Japanese are ...’ at Japanese ‘left-wing’ political gatherings. In Japan, these are words used only by right-wing nationalists. Indeed it is difficult to even imagine liberal-left intellectuals in postwar Japan calling for a ‘true Japanese’ political response (as if such a response was positive, such is the extent to which the idea of ‘good nationalism’ is now regarded as an oxymoron. This is my starting point for an essay in which I want to be attentive to the different roles played by national(ism in the Japanese and Australian political environments.

    Full Text Available This article is dedicated to recounting the main initiative of Nelson Mandela’s government to manage the social resentment inherited from the segregationist regime. I conducted interviews with South African intellectuals committed to the theme of transitional justice and with key personalities who played a critical role in this process. The Truth and Reconciliation Commission is presented as the primary institutional mechanism envisioned for the delicate exercise of redefining social relations inherited from the apartheid regime in South Africa. Its founders declared grandiose political intentions to the detriment of localized more palpable objectives.

    2015-01-01

    In order to assess the effects of displacement and exposure to violence on children's moral reasoning, Colombian children exposed to minimal violence (non-displaced or low-risk) (N = 99) and to extreme violence (displaced or high-risk) (N = 94), evenly divided by gender, at 6-, 9-, and 12 - years of age, were interviewed regarding their evaluation of peer-oriented moral transgressions (hitting and not sharing toys). The vast majority of children evaluated moral transgressions as wrong. Group and age differences were revealed, however, regarding provocation and retaliation. Children who were exposed to violence, in contrast to those with minimum exposure, judged it more legitimate to inflict harm or deny resources when provoked and judged it more okay to retaliate for reasons of retribution. Surprisingly, and somewhat hopefully, all children viewed reconciliation as feasible. The results are informative regarding theories of morality, culture, and the effects of violence on children's social development. PMID:25722543

  13. 'The body remembers': narrating embodied reconciliations of eating disorder and recovery.

    Eli, Karin

    2016-01-01

    After severe illness, there are stories: narrative strands to suture discontinuities of identities, practices, and lives. But within these narratives of illness and recovery, the body's discontinuities stand apart, striking in the materiality of change, in the tangible multiplicity of bodies - healthy, ill, recovering, recovered - that a person can call one's own. Based on longitudinal research interviews with Israeli women who identified as recovered from long-term eating disorders (fieldwork conducted in 2005-2006 and in 2011), this paper explores how these bodily discontinuities are expressed, drawing particular attention to the narrative role of embodied memory in linking past and present-tense bodies and selves. Embodied memory, as narrated by the participants, is deeply, sometimes surprisingly, embedded in lived experience, imbuing recovered bodies with moments of sensory continuity, the past coming into presence through forms of sensation and perception learned at the height of disorder. Examining narrative moments of sensory remembrance, this paper analyses how participants narrate embodied memory as a mode of reflection, self-protection, and dynamic integration, wherein the experience of disorder informs practices of recovery, and the body becomes a site for the reconciliation of past and present.

  14. Anti-Muslim Sentiments and Violence: A Major Threat to Ethnic Reconciliation and Ethnic Harmony in Post-War Sri Lanka

    Full Text Available Following the military defeat of LTTE terrorism in May 2009, the relationship between ethnic and religious groups in Sri Lanka became seriously fragmented as a result of intensified anti-minority sentiments and violence. Consequently, the ethnic Muslims (Moors became the major target in this conflict. The major objective of this study is to critically evaluate the nature and the impact of the anti-Muslim sentiments expressed and violence committed by the extreme nationalist forces during the process of ethnic reconciliation in post-war Sri Lanka. The findings of the study reveal that, with the end of civil war, Muslims have become “another other” and also the target of ethno-religious hatred and violence from the vigilante right-wing ethno-nationalist forces that claim to be protecting the Sinhala-Buddhist nation, race, and culture in Sri Lanka. These acts are perpetrated as part of their tactics aimed to consolidate a strong Sinhala-Buddhist nation—and motivated by the state. Furthermore, the recourse deficit and lack of autonomy within the organizational hierarchy of the Buddhist clergy have motivated the nationalist monks to engage in politics and promote a radical anti-minority rhetoric. This study recommends institutional and procedural reforms to guide and monitor the activities of religious organizations, parties, and movements, together with the teaching of religious tolerance, as the preconditions for ethnic reconciliation and ethnic harmony in post-war Sri Lanka. This study has used only secondary data, which are analyzed in a descriptive and interpretive manner.

    An inaccurate medication history may prevent the discovery of a pre-admission iatrogenic event or lead to interrupted drug therapy during hospitalization. Medication reconciliation is a process that ensures the transfer of medication information at admission to the hospital. The aims of this prospective study were to evaluate the interest in clinical practice of this concept and the resources needed for its implementation. We chose to include patients aged 65 years or over admitted in the internal medicine unit between June and October 2010. We obtained an accurate list of each patient's home medications. This list was then compared with medication orders. All medication variances were classified as intended or unintended. An internist and a pharmacist classified the clinical importance of each unintended variance. Sixty-one patients (mean age: 78 ± 7.4 years) were included in our study. We identified 38 unintended discrepancies. The average number of unintended discrepancies was 0.62 per patient. Twenty-five patients (41%) had one or more unintended discrepancies at admission. The contact with the community pharmacist permitted us to identify 21 (55%) unintended discrepancies. The most common errors were the omission of a regularly used medication (76%) and an incorrect dosage (16%). Our intervention resulted in order changes by the physician for 30 (79%) unintended discrepancies. Fifty percent of the unintended variances were judged by the internist and 76% by the pharmacist to be clinically significant. The admission to the hospital is a critical transition point for the continuity of care in medication management. Medication reconciliation can identify and resolve errors due to inaccurate medication histories. Copyright © 2011 Elsevier Masson SAS. All rights reserved.

    Full Text Available The article analyzes two contemporary movie remakes of the 60s cinemas in Argentina: Aniceto (Leonardo Favio, 2008 and La patota (Santiago Mitre, 2015. The objective is to explore the transformations and continuities between the source texts and the later subsidiary texts. It tries to recognize the immanent issues, the procedural and pragmatic aspects involved in these rewriting operations. The central hypothesis to be demonstrated proposes that both films generate, through different paths, a reconciliation with the past constructing a perspective through the present. In Aniceto, the conciliation gesture occurs in the form of a synthesis of the two tendencies that characterized Favio’s cinema: a first one associated with the aesthetics of modernity versus the second one, in which the approach to the popular universe and other practices belonging to the mass culture predominates. For its part, the work of Santiago Mitre assembles a film of an Argentinean classic movie maker (Daniel Tinayre under the light of the current cinema. Besides, La patota ties the characteristics of a great commercial production with the structure and aesthetic of the «anomalous cinema».

    2015-01-01

    Full Text Available This paper presents a case study about a reunion of the evicted members of the German national minority in Vojvodina, who after almost five decades came to visit their homeland, and the local population in Gakovo. The case study attests about lengthy and very complicated process in resolving post-conflict situations. The process’ launch is dependent on the willingness of the individuals involved to face not only one’s own pain caused by the enemy, but also on ability to comprehend, during an encounter with “the dark side of one’s past”, sufferings and humiliation experienced by the adversary. Awareness and acceptance of one’s own responsibility in the conflict are a prerequisite for forgiveness and reconciliation of the opposing parties. The outcome of this process is uncertain to the very end and conditioned upon the entire network of interlocking political, economic and cultural factors.

  19. Process of Reconciliation in a Postconflict Macedonia

    Full Text Available In this article we will consider reconciliation in a post-conflict Macedonia. When Ohrid Framework Agreement (OFA was signed, the international community greeted the achievements of the international community as it was signed under specific circumstances. Since it stopped the conflict, it had achieved its goal. Legally, the country became a multiethnic one with a power-sharing government. Yet, the political and intellectual elite, which slightly differ from each other, did not invest intellectual and political capital when searching for a specific Macedonian (inter national identity, which goes beyond the limitations of the ethnic definitions and mythology around them. Instead, the national discourse is emphasized. Using the terms such as multiculturalism, multhiethnicity and polylingualisam creates additional confusion. When media and politicians use these phrases and incorporate their own political discourses, the damage is done. Critical thinking is not on the agenda in the educational process and the young people are expected to listen rather than think. There is a need for a structural communication among the citizens, a social link but also a philosophical and maybe an ideological communication, so as to fill in the gaps and avoid further divisions. The only way to accomplish that is to have an open and inclusive society. In order to achieve this, the culture of dialog should be nurtured. It is not enough for Macedonians and Albanians to know each other’s folklore and cultural history. Coexistence requires knowing the modern reality. Structured communication is a key. Absence of public discourse has a positive effect on the society’s wellbeing. A debate is not a threat to the process of creating politics. Instead, it legalizes the decision-making process. The intellectual elite should take the lead, show its grandiosity, and view Macedonia as a whole in a joint narrative, which considers all the specifics of the different cultures

  20. Rational Dialogue between Kosovo and Serbia - Way Toward Reconciliation

    Full Text Available Within a decade, Kosovo has compromised twice: accepting the process of decentralization in order to achieve independence and international recognition, through the President Martti Ahtisaari’s Comprehensive Proposal for the Kosovo Status Settlement (2 February 2007, and finally, by approving to offer autonomy for Kosovo Serbs for the sovereignty, but still within the limits of the Ahtisaari Plan. Coincidentally, the same Serbian political parties which had fought three wars, resulting in dissolution of the state (Former Yugoslavia at that time (the Socialist Party and the Serbian Radical Party, now are in power in the Republic of Serbia, and have the possibility to finally solve the Kosovo case, and to open the perspective for this part, Europe’s black hole, to be engaged in global integration. Statements by senior Serbian politicians are positively shifting, compared to the radicalization of the relations between Albanians and Serbs three decades ago and it is believed that the developments will evolve towards rational choice and acceptance by the parties. Being under pressure by difficult socio-economic situation and need for integration processes, both sides undertake risky and unpopular steps by signing unclear political and verbal agreements on normalization of relations, which may produce difficult solving externalities in the future. The risk lies in the possibility of further damaging the Kosovo’s “piece of the cake”, after every refusal step by the Serbian side, which will damage the interest of Kosovo side according to the “zero sum” game. Analyses of the dialogue process between Kosovo and Serbia reflect the mixed benefits to the parties, resulting in not very soon European integration, and with hope on difficult but necessary reconciliation between Albanians and Serbs in the region. The broken, after the war established, status quo is better than entering into a protracted conflict in the middle of Europe.

    Full Text Available In this article the Old Testament prophetic literature will be the focus of discussion with regard to the matter of restoring broken relationships, be it between God and humans or between humans as such. The relationship between Yahweh and his people was formally established by means of a covenant. The presentation of the prophetic material is done with a narrow focus on the issues of reconciliation and restoration. Prophets and prophetic� texts are selected with the mentioned focus in mind and presented as the results of research done on the chosen texts. It is therefore done with a real awareness of the complexity of the prophetic material and the historical embedding of prophetic material. A detailed discussion of introductory and theological issues are therefore not presented, but taken into account. What result in this paper is a focussed presentation on the mentioned topics in some of the prophetic material. Although the word reconciliation is not an Old Testament concept, it is clear that the idea of re-establishment and renewal of� the relationship between God and people was ever present. The prophets had the duty to address the reasons for damage to this covenant relationship and to warn the people of the consequences if they continue to disobey the stipulations and ethical demands of this relationship. The prophets not only served as witnesses of the efforts of Yahweh to reconcile with his people, but also as instruments to bring it about.�

    Few studies have explored the impact of using different methods for obtaining accurate medication histories on medication safety. This study was conducted to compare the accuracy and clinical impact of pharmacist medication histories obtained by electronic medical record review (EMRR) alone with those obtained by direct interviews combined with EMRR. This 18-week prospective study included patients who were admitted to the Inpatient Medicine Service at the study institution and who had a pharmacist-conducted medication reconciliation EMRR within 48 hours of hospital admission. A chart review was performed to collect data to determine whether differences existed in the number of discrepancies, recommendations, and medication errors between the EMRR alone group compared to the EMRR combined with the patient interview group. Five hundred thirteen discrepancies were identified with the EMRR group compared to 986 from the combined EMRR and patient interview group (P < .001). Significantly more recommendations were made in the combination interview group compared to the EMRR alone group (260 vs 97; P < .001). Fewer medication errors were identified for the EMRR alone group compared to the combination interview group (55 vs 134; P < .001). The most common errors were omitted medications followed by extra dose/failure to discontinue therapy and wrong dose/frequency errors. Pharmacist-conducted admission medication interviews combined with EMRR can potentially identify harmful medication discrepancies and prevent medication errors.

    Component degradation modeling being developed to understand the aging process can have many applications with potential advantages. Previous work has focused on developing the basic concepts and mathematical development of a simple degradation model. Using this simple model, times of degradations and failures occurrences were analyzed for standby components to detect indications of aging and to infer the effectiveness of maintenance in preventing age-related degradations from transforming to failures. Degradation modeling approaches can have broader applications in aging studies and in this paper, the authors discuss some of the extensions and applications of degradation modeling. The extensions and applications of the degradation modeling approaches discussed are: (a) theoretical developments to study reliability effects of different maintenance strategies and policies, (b) relating aging-failure rate to degradation rate, and (c) application to a continuously operating component

    Cyril C Grueter

    Full Text Available Humans are unique among primates for not only engaging in same-sex sexual acts, but also forming homosexual pair bonds. To shed light on the evolutionary origins of homosexuality, data on the occurrence and contexts of same-sex behavior from nonhuman primates may be of particular significance. Homosexual behavior involving females is poorly researched in most primate taxa, exceptions being Japanese macaques, rhesus macaques, Hanuman langurs and bonobos. We present data on homosexual behavior in female mountain gorillas in the Virunga Volcanoes (Rwanda and test four functional hypotheses, namely reconciliation, affiliation, dominance expression and sexual arousal. Homosexual interactions between females involved both ventro-dorsal and ventro-ventral copulations accompanied by vocalizations and courtship displays. The only sociosexual hypothesis that received partial empirical support is the social status hypothesis, i.e., that mounting reaffirms the dominance hierarchy. There is also some limited evidence that same-sex behavior reflects an overall state of arousal or is triggered via a 'pornographic' effect. An adaptive function of female homosexual behavior is not readily apparent, and we tentatively conclude (until a more rigorous test becomes available that it may simply be related to sexual gratification or that it is an evolutionary by-product of an adaptation.

    One method for addressing existing peer review limitations is the assignment of peer review cases on a completely blinded basis, in which the peer reviewer would create an independent report which can then be cross-referenced with the primary reader report of record. By leveraging existing computerized data mining techniques, one could in theory automate and objectify the process of report data extraction, classification, and analysis, while reducing time and resource requirements intrinsic to manual peer review report analysis. Once inter-report analysis has been performed, resulting inter-report discrepancies can be presented to the radiologist of record for review, along with the option to directly communicate with the peer reviewer through an electronic data reconciliation tool aimed at collaboratively resolving inter-report discrepancies and improving report accuracy. All associated report and reconciled data could in turn be recorded in a referenceable peer review database, which provides opportunity for context and user-specific education and decision support.

    In this report, the dose estimate for CY 1995 is reconciled by month wih actual doses received. Results of the reconciliation were used to revise estimates of worker dose for CY 1996. Resulting dose estimate for the facility is also included. Support for two major programs (B-Cell Cleanout and Surveillance and Maintenance) accounts for most of the exposure received by workers in the faility. Most of the expousre received by workers comes from work in the Radiochemical Engineering Complex airlock. In spite of schedule and work scope changes during CY 1995, dose estimates were close to actual exposures received. A number of ALARA measures were taken throughout the year; exposure reduction due to those was 20.6 Man-Rem, a 28% reduction from the CY 1995 estimate. Baseline estimates for various tasks in the facility were used to compile the CY 1996 dose estimate of 45.4 Man-Rem; facility goal for CY 1996 is to reduce worker dose by 20%, to 36.3 Man-Rem

    Inventories of buried (generally meaning disposed of) transuranic (TRU) wastes at Oak Ridge National Laboratory (ORNL) have been estimated for site remediation and waste management planning over a period of about two decades. Estimates were required because of inadequate waste characterization and incomplete disposal records. For a variety of reasons, including changing definitions of TRU wastes, differing objectives for the estimates, and poor historical data, the published results have sometimes been in conflict. The purpose of this review was (1) to attempt to explain both the rationale for and differences among the various estimates, and (2) to update the estimates based on more recent information obtained from waste characterization and from evaluations of ORNL waste data bases and historical records. The latter included information obtained from an expert panel's review and reconciliation of inconsistencies in data identified during preparation of the ORNL input for the third revision of the Baseline Inventory Report for the Waste Isolation Pilot Plant. The results summarize current understanding of the relationship between past estimates of buried TRU wastes and provide the most up-to-date information on recorded burials thereafter. The limitations of available information on the latter and thus the need for improved waste characterization are highlighted

The conference, titled “Beyond Reconciliation,” was held at the University of Calgary Downtown Campus on Nov. 21, 2016 and was attended by 73 participants. This included Indigenous elders, chiefs and leaders, and members of Indigenous organizations, including a women’s group. Also included were members of universities and academic institutions, including students; industry representatives from the oil and gas, pipeline, forestry, electricity, legal and financial sectors; as well as representatives from government and regulatory agencies. The purpose of the conference was established with the following abstract, which was circulated to speakers and participants: The School of Public Policy is establishing a new Indigenous Policy program in order to produce widely disseminated research and engage in outreach that covers an array of policy areas, such as health, education, self-government, and natural resource development. The program will directly engage Indigenous communities in the search for original, long-term, and evidence-based solutions, as part of an effort to improve our national capacity in problem-solving and policy development. The conference will provide a platform to launch the program, showcasing preliminary research and providing a venue for discussion of policy solutions. The conference included three moderated panel sessions and a keynote speaker.1 The first panel considered business and entrepreneurship in Indigenous communities; the second panel showcased case studies that are examining the experiences of Indigenous communities with natural resource development projects, and particularly their experiences with consultation and engagement.

  19. Medical identity theft: prevention and reconciliation initiatives at Massachusetts General Hospital.

    Judson, Timothy; Haas, Mark; Lagu, Tara

    2014-07-01

    Medical identity theft refers to the misuse of another individual's identifying medical information to receive medical care. Beyond the financial burden on patients, hospitals, health insurance companies, and government insurance programs, undetected cases pose major patient safety challenges. Inaccuracies in the medical record may persist even after the theft has been identified because of restrictions imposed by patient privacy laws. Massachusetts General Hospital (MGH; Boston) has conducted initiatives to prevent medical identity theft and to better identify and respond to cases when they occur. Since 2007, MGH has used a notification tree to standardize reporting of red flag incidents (warning signs of identity theft, such as suspicious personal identifiers or account activity). A Data Integrity Dashboard allows for tracking and reviewing of all potential incidents of medical identity theft to detect trends and targets for mitigation. An identity-checking policy, VERI-(Verify Everyone's Identity) Safe Patient Care, requires photo identification at every visit and follow-up if it is not provided. Data from MGH suggest that an estimated 120 duplicate medical records are created each month, 25 patient encounters are likely tied to identity theft or fraud each quarter, and 14 patients are treated under the wrong medical record number each year. As of December 2013, 80%-85% of patients were showing photo identification at appointments. Although an organization's policy changes and educational campaigns can improve detection and reconciliation of medical identity theft cases, national policies should be implemented to streamline the process of correcting errors in medical records, reduce the financial disincentive for hospitals to detect and report cases, and create a single point of entry to reduce the burden on individuals and providers to reconcile cases.

  20. Stochastic E2F activation and reconciliation of phenomenological cell-cycle models.

    The transition of the mammalian cell from quiescence to proliferation is a highly variable process. Over the last four decades, two lines of apparently contradictory, phenomenological models have been proposed to account for such temporal variability. These include various forms of the transition probability (TP) model and the growth control (GC) model, which lack mechanistic details. The GC model was further proposed as an alternative explanation for the concept of the restriction point, which we recently demonstrated as being controlled by a bistable Rb-E2F switch. Here, through a combination of modeling and experiments, we show that these different lines of models in essence reflect different aspects of stochastic dynamics in cell cycle entry. In particular, we show that the variable activation of E2F can be described by stochastic activation of the bistable Rb-E2F switch, which in turn may account for the temporal variability in cell cycle entry. Moreover, we show that temporal dynamics of E2F activation can be recast into the frameworks of both the TP model and the GC model via parameter mapping. This mapping suggests that the two lines of phenomenological models can be reconciled through the stochastic dynamics of the Rb-E2F switch. It also suggests a potential utility of the TP or GC models in defining concise, quantitative phenotypes of cell physiology. This may have implications in classifying cell types or states.

    Full Text Available This article passes from Christianity to African Religion and back again, in order to gain new insight on reconciliation. Traditional Christian reconciliation models are valuable but also contextual and limited; thus new models should be sought. African myths of community, acceptance and rebellion offer alternative ways of understanding reconciliation. When evaluated according to the principles of integration and transcendence, these myths meet the criteria of better religion and emphasise Christian notions that are often ignored in tradition Christianity. These new African-inspired insights can be used in Christian liturgy as a number of examples prove.

    In this thesis tools of data reconciliation are used to integrate available information into scientific and policy models of greenhouse gases. The role of uncertainties in scientific and policy models of global climate change is examined, and implications for global change policy are drawn. Methane is the second most important greenhouse gas. Global sources and sinks of methane have significant uncertainties. A chance constrained methodology was developed and used to perform inversions on the global methane cycle. Budgets of methane that are consistent with source fluxes, isotopic and ice core measurements were determined. While it is not possible to come up with a single budget for CH{sub 4}, performing the calculation with a number of sets of assumed priors suggests a convergence in the allowed range for sources. In some cases -- wetlands (70-130 Tg/yr), rice paddies (60-125 Tg/yr) a significant reduction in the uncertainty of the source estimate is achieved. Our results compare favorably with the most recent measurements of flux estimates. For comparison, a similar analysis using bayes monte carlo simulation was performed. The question of the missing sink for carbon remains unresolved. Two analyses that attempt to quantify the missing sink were performed. First, a steady state analysis of the carbon cycle was used to determine the pre-industrial inter-hemispheric carbon concentration gradient. Second, a full blown dynamic inversion of the carbon cycle was performed. An advection diffusion ocean model with surface chemistry, coupled to box models of the atmosphere and the biosphere was inverted to fit available measurements of {sup 12}C and {sup 14}C carbon isotopes using Differential-Algebraic Optimization. The model effectively suggests that the {open_quotes}missing{close_quotes} sink for carbon is hiding in the biosphere. Scenario dependent trace gas indices were calculated for CH{sub 4}, N{sub 2}O, HCFC-22.

    Full Text Available That the twentieth century witnessed massive secularisation in Europe and certain other parts of the world is beyond dispute, as is the fact that the general phenomenon of religion and its role as a factor shaping history remain potent on a broad, international scale. There is no consensus, however, about the future place or status of Western Christian civilisation or �Christendom� in a shrinking and pluralistic world also struggling with the challenge of reconciliation. During the 1950s two controversial giants of� British historiography, Arnold Toynbee and HR Trevor-Roper clashed on this issue. Their severe differences of opinion were conditioned in part by the Cold War, general retreat of imperialism from Africa and Asia, and the growth of the economic, military, and political power of previously colonised or otherwise subjugated nations.

    The inflationary cosmology paradigm is very successful in explaining the CMB anisotropy to the percent level. Besides the dependence on the inflationary model, the power spectra, spectral tilt and non-Gaussianity of the CMB temperature fluctuations also depend on the initial state of inflation. Here, we examine to what extent these observables are affected by our ignorance in the initial condition for inflationary perturbations, due to unknown new physics at a high scale M. For initial states that satisfy constraints from backreaction, we find that the amplitude of the power spectra could still be significantly altered, while the modification in bispectrum remains small. For such initial states, M has an upper bound of a few tens of H, with H being the Hubble parameter during inflation. We show that for M ∼ 20H, such initial states always (substantially) suppress the tensor to scalar ratio. In particular we show that such a choice of initial conditions can satisfactorily reconcile the simple ½m 2 φ 2 chaotic model with the Planck data [1-3

    The Next Generation Nuclear Plant (NGNP), the Deep Burn Pebble Bed Reactor (DB-PBR) and the Deep Burn Prismatic Block Reactor (DB-PMR) are all based on fuels that use TRISO particles as their fundamental constituent. The TRISO particle properties include very high durability in radiation environments, hence the designs reliance on the TRISO to form the principal barrier to radioactive materials release. This durability forms the basis for the selection of this fuel type for applications such as Deep Bun (DB), which require exposures up to four times those expected for light water reactors. It follows that the study and prediction of the durability of TRISO particles must be carried as part of the safety and overall performance characterization of all the designs mentioned above. Such evaluations have been carried out independently by the performers of the DB project using independently developed codes. These codes, PASTA, PISA and COPA, incorporate models for stress analysis on the various layers of the TRISO particle (and of the intervening matrix material for some of them), model for fission products release and migration then accumulation within the SiC layer of the TRISO particle, just next to the layer, models for free oxygen and CO formation and migration to the same location, models for temperature field modeling within the various layers of the TRISO particle and models for the prediction of failure rates. All these models may be either internal to the code or external. This large number of models and the possibility of different constitutive data and model formulations and the possibility of a variety of solution techniques makes it highly unlikely that the model would give identical results in the modeling of identical situations. The purpose of this paper is to present the results of an inter-comparison between the codes and to identify areas of agreement and areas that need reconciliation. The inter-comparison has been carried out by the cooperating

  10. Genome-scale metabolic model of the fission yeast Schizosaccharomyces pombe and the reconciliation of in silico/in vivo mutant growth

    Science.gov (United States)

    2012-01-01

    Background Over the last decade, the genome-scale metabolic models have been playing increasingly important roles in elucidating metabolic characteristics of biological systems for a wide range of applications including, but not limited to, system-wide identification of drug targets and production of high value biochemical compounds. However, these genome-scale metabolic models must be able to first predict known in vivo phenotypes before it is applied towards these applications with high confidence. One benchmark for measuring the in silico capability in predicting in vivo phenotypes is the use of single-gene mutant libraries to measure the accuracy of knockout simulations in predicting mutant growth phenotypes. Results Here we employed a systematic and iterative process, designated as Reconciling In silico/in vivo mutaNt Growth (RING), to settle discrepancies between in silico prediction and in vivo observations to a newly reconstructed genome-scale metabolic model of the fission yeast, Schizosaccharomyces pombe, SpoMBEL1693. The predictive capabilities of the genome-scale metabolic model in predicting single-gene mutant growth phenotypes were measured against the single-gene mutant library of S. pombe. The use of RING resulted in improving the overall predictive capability of SpoMBEL1693 by 21.5%, from 61.2% to 82.7% (92.5% of the negative predictions matched the observed growth phenotype and 79.7% the positive predictions matched the observed growth phenotype). Conclusion This study presents validation and refinement of a newly reconstructed metabolic model of the yeast S. pombe, through improving the metabolic model’s predictive capabilities by reconciling the in silico predicted growth phenotypes of single-gene knockout mutants, with experimental in vivo growth data.

  11. Dynamical compensation and structural identifiability of biological models: Analysis, implications, and reconciliation.

    2017-11-01

    The concept of dynamical compensation has been recently introduced to describe the ability of a biological system to keep its output dynamics unchanged in the face of varying parameters. However, the original definition of dynamical compensation amounts to lack of structural identifiability. This is relevant if model parameters need to be estimated, as is often the case in biological modelling. Care should we taken when using an unidentifiable model to extract biological insight: the estimated values of structurally unidentifiable parameters are meaningless, and model predictions about unmeasured state variables can be wrong. Taking this into account, we explore alternative definitions of dynamical compensation that do not necessarily imply structural unidentifiability. Accordingly, we show different ways in which a model can be made identifiable while exhibiting dynamical compensation. Our analyses enable the use of the new concept of dynamical compensation in the context of parameter identification, and reconcile it with the desirable property of structural identifiability.

  12. Discerning a theological agenda for spatial justice in South Africa: An imperative for sustained reconciliation

    Directory of Open Access Journals (Sweden)

    Stephan de Beer

    2016-11-01

    Full Text Available A spatial turn has occurred in various disciplines over the past decades. This article holds that it has not occurred in a similar decisive manner in theological discourse and not in South Africa in particular. After considering the necessity of a spatial turn and spatial consciousness, the article examines the concept of spatial justice against the backdrop of how injustice was and is spatially expressed in South African cities. Considering the way in which South African cities have evolved since the Native Land Act of 1913 – the segregated and apartheid city and the (postapartheid city – the article then argues that deep and sustained reconciliation will be impossible should current spatial patterns of segregation, exclusion and injustice continue. It advocates theological and ecclesial participation in a national agenda for spatial transformation, to be fleshed out in relation to four interconnected challenges: land, landlessness, housing and home; the ‘creative destruction’ of neighbourhoods, gentrification and the displacement of the poor; participation in city-making (from below and transformative spatial interventions; and close collaboration with social movements working for spatial justice. It concludes by asserting that such a trans- and/or postdisciplinary agenda for spatial justice would participate with the Spirit to mend the oikos of God.

    Full Text Available Genome-wide global detection of genes involved in horizontal gene transfer (HGT remains an active area of research in medical microbiology and evolutionary genomics. Utilizing the explicit evolutionary method of comparing topologies of a total of 154,805 orthologous gene trees against corresponding 16S rRNA “reference” trees, we previously detected a total of 660,894 candidate HGT events in 2,472 completely-sequenced prokaryotic genomes. Here, we report an HGT-index for each individual gene-reference tree pair reconciliation, representing the total number of detected HGT events on the gene tree divided by the total number of genomes (taxa member of that tree. HGT-index is thus a simple measure indicating the sensitivity of prokaryotic genes to participate (or not participate in HGT. Our preliminary list provides HGT-indices for a total of 69,365 genes (detected in >10 and <50% available prokaryotic genomes that are involved in a wide range of biological processes such as metabolism, information, and bacterial response to environment. Identification of horizontally-derived genes is important to combat antibiotic resistance and is a step forward toward reconstructions of improved phylogenies describing the history of life. Our effort is thus expected to benefit ongoing research in the fields of clinical microbiology and evolutionary biology.

    Recent years have witnessed an explosion of extensive geolocated datasets related to human movement, enabling scientists to quantitatively study individual and collective mobility patterns, and to generate models that can capture and reproduce the spatiotemporal structures and regularities in human trajectories. The study of human mobility is especially important for applications such as estimating migratory flows, traffic forecasting, urban planning, and epidemic modeling. In this survey, we review the approaches developed to reproduce various mobility patterns, with the main focus on recent developments. This review can be used both as an introduction to the fundamental modeling principles of human mobility, and as a collection of technical methods applicable to specific mobility-related problems. The review organizes the subject by differentiating between individual and population mobility and also between short-range and long-range mobility. Throughout the text the description of the theory is intertwined with real-world applications.

    2007-01-01

    Full Text Available La problematización de sentido integra el horizonte histórico y cultural de la modernidad occidental, donde se abre la posibilidad de una explosión de sentidos. En este escenario, el pensamiento filosófico se enfrenta a la crisis de fundamentación última y la dificultad para traducir, en términos de verdad y racionalidad, la reflexión en el campo de la filosofía y las ciencias humanas. En este sentido, existen por lo menos dos alternativas para que las filosofías modernas, sin renunciar a la pretensión de universalidad, se encuentren con su propio tiempo histórico: la hermenéutica y la crítica dialéctica. El pensamiento de Paul Ricoeur, para quien hermenéutica y crítica son dos momentos necesarios a la reflexión filosófica, promueve la reconciliación entre estas dos tradiciones de la filosofía moderna. Sin embargo, la tesis que se plantea en este ensayo es que las estrategias reconciliadoras de Ricoeur corresponden, en último término, a la construcción de su propio pensamiento filosófico. Es decir, el movimiento reconciliador del pensamiento ricoeurniano es parte de su propio proyecto filosófico, a saber, el de hacer emerger una hermenéutica crítica y una ética ontológicamente fundada.The problematization of sense includes the historical and cultural horizon of the western culture, where it opens the possibility for an explosion of senses. In this modernity setting, the philosophical thought faces the crisis of the last fundamentation and the difficulty for translating, in terms of truth and racionality, the reflection in the field of philosophy and human sciences. In this context, there are at least two alternatives for modern philosophy- without resigning the pretension of universality- to find its own historical time: the hermeneuthic and the dialectical criticism. The Paul Ricoeur thought, for whom hermeneuthical and critical are two necessary moments to the philosophical reflection, promotes the reconciliation

    To assess the accuracy of pharmaceutical anamnesis obtained at the Emergency Department (ED) of a tertiary referral hospital and to determine the prevalence of medication reconciliation errors (RE). This was a single-center, prospective, interventional study. The home medication list obtained by a pharmacist was compared with the one recorded by a doctor to identify inaccuracies. Subsequently, the home medication list was compared with the active prescription at the ED. All unexplained discrepancies were checked with the doctor in charge to evaluate if a RE has occurred. An univariate analysis was performed to identify factors associated with RE. The pharmacist identified a higher number of drugs than doctors (6.89 versus 5.70; P<0.05). Only 39% of the drugs obtained by doctors were properly written down in the patient's record. The main cause of discrepancy was omission of information regarding the name of the drug (39%) or its dosage (33%). One hundred and fifty-seven RE were identified and they affected 85 patients (43%), mainly related to information omission (62%). Age and polymedication were identified as main risk factors of RE. The presence of a caregiver or relative in the ED was judged to be a protective factor. No relationship was found between inaccuracies in the registries and RE. The process of obtaining a proper pharmaceutical anamnesis still needs improvement. The pharmacist may play a role in the process of obtaining a good quality anamnesis and increase patient safety by detecting RE. Better information systems are needed to avoid this type of incidents.

    Even while pharmacy practice evolves to a more patient-centric mode of practice, local hospitals, due to high patient load as well as space and resource constraints, find it challenging to conduct thorough medication review and physical medication reconciliation for all patients. In light of this, optimizing the local current healthcare system to involve community pharmacists in the care of patients from public hospitals could potentially better cater to the healthcare needs of the older population. Due to easy accessibility, community pharmacies are often the first point of contact in the healthcare system. Project Octo-Pills aims to engage community pharmacists in the collaborative care of patients from a tertiary hospital, providing patients with quality medication reconciliation and review services from a more convenient location within their neighborhood. This paper describes the model for this pilot initiative. Copyright © 2017 Elsevier Inc. All rights reserved.

  1. Emergent patterns of social affiliation in primates, a model.

    2009-12-01

    Full Text Available Many patterns of affiliative behaviour have been described for primates, for instance: reciprocation and exchange of grooming, grooming others of similar rank, reconciliation of fights, and preferential reconciliation with more valuable partners. For these patterns several functions and underlying cognitive processes have been suggested. It is, however, difficult to imagine how animals may combine these diverse considerations in their mind. Although the co-variation hypothesis, by limiting the social possibilities an individual has, constrains the number of cognitive considerations an individual has to take, it does not present an integrated theory of affiliative patterns either. In the present paper, after surveying patterns of affiliation in egalitarian and despotic macaques, we use an individual-based model with a high potential for self-organisation as a starting point for such an integrative approach. In our model, called GrooFiWorld, individuals group and, upon meeting each other, may perform a dominance interaction of which the outcomes of winning and losing are self-reinforcing. Besides, if individuals think they will be defeated, they consider grooming others. Here, the greater their anxiety is, the greater their "motivation" to groom others. Our model generates patterns similar to many affiliative patterns of empirical data. By merely increasing the intensity of aggression, affiliative patterns in the model change from those resembling egalitarian macaques to those resembling despotic ones. Our model produces such patterns without assuming in the mind of the individual the specific cognitive processes that are usually thought to underlie these patterns (such as recordkeeping of the acts given and received, a tendency to exchange, memory of the former fight, selective attraction to the former opponent, and estimation of the value of a relationship. Our model can be used as a null model to increase our understanding of affiliative

    Application layer firewalls protect the trusted area network against information security risks. However, firewall performance may affect user experience. Therefore, performance analysis plays a significant role in the evaluation of application layer firewalls. This paper presents an analytic model of the application layer firewall, based on a system analysis to evaluate the capability of the firewall. In order to enable users to improve the performance of the application layer firewall with limited resources, resource allocation was evaluated to obtain the optimal resource allocation scheme in terms of throughput, delay, and packet loss rate. The proposed model employs the Erlangian queuing model to analyze the performance parameters of the system with regard to the three layers (network, transport, and application layers). Then, the analysis results of all the layers are combined to obtain the overall system performance indicators. A discrete event simulation method was used to evaluate the proposed model. Finally, limited service desk resources were allocated to obtain the values of the performance indicators under different resource allocation scenarios in order to determine the optimal allocation scheme. Under limited resource allocation, this scheme enables users to maximize the performance of the application layer firewall.

    2005-01-01

    Reactor thermal power is an important operational parameter in many respects such as nuclear safety, reactor physics or evaluation of turbine thermal performance. Thermal power of a pressurized water reactor is determined on the basis of the steam generator thermal balance. The balance can be made in several variants differing from one another by the selection of different measuring circuits whose data are used in the balancing. In principle, no one such variant gives the true value of the thermal power. Among the variant values, the one nearest to the unknown true value of reactor thermal power is probably the value calculated with the lowest uncertainty. The determination of such uncertainty is not easy and its value can make even several percent, which has significant economic consequences. This paper presents the method of data reconciliation and its application to the data of the third of Dukovany NPP. The data reconciliation method allows to exploit all the information which process data contain. It is based on the statistical adjustment of the redundant data in such a way that the adjusted data obey generally valid laws of nature (e.g. conservation laws). Mass and energy balances based on the data not yet reconciled do not obey those laws because of measurement errors. For data reconciliation in Dukovany, a detailed model of mass and energy flows describing the 3rd unit from steam generators to alternator and condenser was set up. Laws of mass and energy conservation and phase equilibrium in water-steam systems are thus fulfilled. Moreover, the user can model momentum balances in pipelines and create other equations, which are respected during calculation. The data reconciliation is done regularly for hourly averages (Authors)

General usability model consist of general dimension for evaluating mobile application however requirements for the hearing-impaired are overlooked and often scanted. This led towards mobile application developed for the hearing-impaired are left unused. It is also apparent that these usability models do not consider accessibility dimensions according to the requirement of the special users. This complicates the work of usability practitioners as well as academician that practices research usability when application are developed for the specific user needs. To overcome this issue, dimension chosen for the hearing-impaired are ensured to be align with the real need of the hearing-impaired mobile application. Besides literature studies, requirements for the hearing-impaired mobile application have been identified through interview conducted with hearing-impaired mobile application users that were recorded as video outputs and analyzed using Nvivo. Finally total of 6 out of 15 dimensions gathered are chosen for the proposed model and presented.

    Friese, Ryan D.; Tallent, Nathan R.; Vishnu, Abhinav; Kerbyson, Darren J.; Hoisie, Adolfy

    2017-05-30

    Many applications have irregular behavior --- non-uniform input data, input-dependent solvers, irregular memory accesses, unbiased branches --- that cannot be captured using today's automated performance modeling techniques. We describe new hierarchical critical path analyses for the \\Palm model generation tool. To create a model's structure, we capture tasks along representative MPI critical paths. We create a histogram of critical tasks with parameterized task arguments and instance counts. To model each task, we identify hot instruction-level sub-paths and model each sub-path based on data flow, instruction scheduling, and data locality. We describe application models that generate accurate predictions for strong scaling when varying CPU speed, cache speed, memory speed, and architecture. We present results for the Sweep3D neutron transport benchmark; Page Rank on multiple graphs; Support Vector Machine with pruning; and PFLOTRAN's reactive flow/transport solver with domain-induced load imbalance.

    Tian, Naishuo

    2006-01-01

    A classical queueing model consists of three parts - arrival process, service process, and queue discipline. However, a vacation queueing model has an additional part - the vacation process which is governed by a vacation policy - that can be characterized by three aspects: 1) vacation start-up rule; 2) vacation termination rule, and 3) vacation duration distribution. Hence, vacation queueing models are an extension of classical queueing theory. Vacation Queueing Models: Theory and Applications discusses systematically and in detail the many variations of vacation policy. By allowing servers to take vacations makes the queueing models more realistic and flexible in studying real-world waiting line systems. Integrated in the book's discussion are a variety of typical vacation model applications that include call centers with multi-task employees, customized manufacturing, telecommunication networks, maintenance activities, etc. Finally, contents are presented in a "theorem and proof" format and it is invaluabl...

  11. On modeling complex interplay in small-scale self-organized socio-hydrological systems

    Science.gov (United States)

    Muneepeerakul, Rachata

    2017-04-01

    Successful and sustainable socio-hydrological systems, as in any coupled natural human-systems, require effective governance, which depends on the existence of proper infrastructure (both hard and soft). Recent work has addressed systems in which resource users and the organization responsible for maintaining the infrastructure are separate entities. However, many socio-hydrological systems, especially in developing countries, are small and without such formal division of labor; rather, such division of labor typically arises from self-organization within the population. In this work, we modify and mathematically operationalize a conceptual framework by developing a system of differential equations that capture the strategic behavior within such a self-organized population, its interplay with infrastructure characteristics and hydrological dynamics, and feedbacks between these elements. The model yields a number of insightful conditions related to long-term sustainability and collapse of the socio-hydrological system in the form of relationships between biophysical and social factors. These relationships encapsulate nonlinear interactions of these factors. The modeling framework is grounded in a solid conceptual foundation upon which additional modifications and realism can be built for potential reconciliation between socio-hydrology with other related fields and further applications.

  12. Validation of nuclear models used in space radiation shielding applications

    International Nuclear Information System (INIS)

    Norman, Ryan B.; Blattnig, Steve R.

    2013-01-01

    A program of verification and validation has been undertaken to assess the applicability of models to space radiation shielding applications and to track progress as these models are developed over time. In this work, simple validation metrics applicable to testing both model accuracy and consistency with experimental data are developed. The developed metrics treat experimental measurement uncertainty as an interval and are therefore applicable to cases in which epistemic uncertainty dominates the experimental data. To demonstrate the applicability of the metrics, nuclear physics models used by NASA for space radiation shielding applications are compared to an experimental database consisting of over 3600 experimental cross sections. A cumulative uncertainty metric is applied to the question of overall model accuracy, while a metric based on the median uncertainty is used to analyze the models from the perspective of model development by examining subsets of the model parameter space.

    1995-08-01

    Over the past decade, the US Department of Energy (DOE) and other agencies have faced increasing scrutiny for a wide range of environmental issues related to past and current practices. A number of large-scale applications have been undertaken that required analysis of large numbers of potential environmental issues over a wide range of environmental conditions and contaminants. Several of these applications, referred to here as large-scale applications, have addressed long-term public health risks using a holistic approach for assessing impacts from potential waterborne and airborne transport pathways. Multimedia models such as the Multimedia Environmental Pollutant Assessment System (MEPAS) were designed for use in such applications. MEPAS integrates radioactive and hazardous contaminants impact computations for major exposure routes via air, surface water, ground water, and overland flow transport. A number of large-scale applications of MEPAS have been conducted to assess various endpoints for environmental and human health impacts. These applications are described in terms of lessons learned in the development of an effective approach for large-scale applications

    Full Text Available With the increasing number of mobile applications, there has more challenging network management tasks to resolve. Users also face security issues of the mobile Internet application when enjoying the mobile network resources. Identifying applications that correspond to network traffic can help network operators effectively perform network management. The existing mobile application recognition technology presents new challenges in extensibility and applications with encryption protocols. For the existing mobile application recognition technology, there are two problems, they can not recognize the application which using the encryption protocol and their scalability is poor. In this paper, a mobile application identification method based on Hidden Markov Model(HMM is proposed to extract the defined statistical characteristics from different network flows generated when each application starting. According to the time information of different network flows to get the corresponding time series, and then for each application to be identified separately to establish the corresponding HMM model. Then, we use 10 common applications to test the method proposed in this paper. The test results show that the mobile application recognition method proposed in this paper has a high accuracy and good generalization ability.

    2017-11-01

    It has proven to be a challenge for health care organizations to achieve the Triple Aim. In the business literature, business model frameworks have been used to understand how organizations are aligned to achieve their goals. We conducted a systematic literature review with an explanatory synthesis approach to understand how business model frameworks have been applied in health care. We found a large increase in applications of business model frameworks during the last decade. E-health was the most common context of application. We identified six applications of business model frameworks: business model description, financial assessment, classification based on pre-defined typologies, business model analysis, development, and evaluation. Our synthesis suggests that the choice of business model framework and constituent elements should be informed by the intent and context of application. We see a need for harmonization in the choice of elements in order to increase generalizability, simplify application, and help organizations realize the Triple Aim.

  3. A pharmacy-based medication reconciliation and review program in hemodialysis patients: a prospective study

    Directory of Open Access Journals (Sweden)

    Patricia NJ

    2016-09-01

    Full Text Available Background: Hemodialysis (HD patients are on multiple medications, see many prescribers and have many hospitalizations which put them at risk for medication record discrepancies and medication related problems (MRP. Being able to effectively identify and reconcile these medication issues is crucial in reducing hospitalizations, morbidities, and mortalities. The care of the hemodialysis patients can be enhanced by incorporating a pharmacist into the interprofessional team. There is little data in the literature on medication record discrepancies and MRP’s in dialysis patients. Objective: The objectives of this research were to determine the types of medication discrepancies and MRPs in dialysis patients and if recommendations for changes based on these findings were accepted by providers. Methods: Patients were asked to bring medications to the dialysis unit for review. Discrepancy and MRP recommendations were communicated to the unit staff via written progress notes. A follow-up was performed an average of 33 days later to determine if the recommendations were accepted. Results: Overall, in 93 unique patients, 376 discrepancies (3.1 per patient and 64 MRPs (0.5 per patient were identified. The most common type of discrepancy and MRP was drug omission and indication without drug, respectively. Of the total 440 interventions, 77% were ultimately accepted. Discrepancies were more likely to be accepted as compared to MRPs (85% vs. 27%, respectively. Conclusion: Medication record discrepancies and MRPs are common in dialysis patients. Recommendations related to discrepancies were more likely to be accepted by the providers as compared to MRPs. Medication records became inaccurate within 12 months. A pharmacy-based medication reconciliation and review program may have an important impact on the care of hemodialysis patients.

    2012-01-01

    Highlights: ► Two known conductance models for application in VVER-1000 thermal–hydraulic code are examined. ► An optimized gap conductance model is developed which can predict the gap conductance in good agreement with FSAR data. ► The licensed thermal–hydraulic code is coupled with the gap conductance model predictor externally. -- Abstract: The modeling of gap conductance for application in VVER-1000 thermal–hydraulic codes is addressed. Two known models, namely CALZA-BINI and RELAP5 gap conductance models, are examined. By externally linking of gap conductance models and COBRA-EN thermal hydraulic code, the acceptable range of each model is specified. The result of each gap conductance model versus linear heat rate has been compared with FSAR data. A linear heat rate of about 9 kW/m is the boundary for optimization process. Since each gap conductance model has its advantages and limitation, the optimized gap conductance model can predict the gap conductance better than each of the two other models individually.

    2011-01-01

    Full Text Available Gaps in information about patient medication adherence may contribute to preventable adverse drug events and patient harm. Hence, health-quality advocacy groups, including the Joint Commission, have called for the implementation of standardized processes to collect and compare patient medication lists. This manuscript describes the implementation of a self-service patient kiosk intended to check in patients for a clinic appointment and collect a medication adherence history, which is then available through the electronic health record. We used business process engineering and simulation modeling to analyze existing workflow, evaluate technology impact on clinic throughput, and predict future infrastructure needs. Our empiric data indicated that a multi-function healthcare kiosk offers a feasible platform to collect medical history data. Furthermore, our simulation model showed a non-linear association between patient arrival rate, kiosk number, and estimated patient wait times. This study provides important data to help administrators and healthcare executives predict infrastructure needs when considering the use of self-service kiosks.

  7. Application of Improved Radiation Modeling to General Circulation Models

    Michael J Iacono

    2011-04-07

    This research has accomplished its primary objectives of developing accurate and efficient radiation codes, validating them with measurements and higher resolution models, and providing these advancements to the global modeling community to enhance the treatment of cloud and radiative processes in weather and climate prediction models. A critical component of this research has been the development of the longwave and shortwave broadband radiative transfer code for general circulation model (GCM) applications, RRTMG, which is based on the single-column reference code, RRTM, also developed at AER. RRTMG is a rigorously tested radiation model that retains a considerable level of accuracy relative to higher resolution models and measurements despite the performance enhancements that have made it possible to apply this radiation code successfully to global dynamical models. This model includes the radiative effects of all significant atmospheric gases, and it treats the absorption and scattering from liquid and ice clouds and aerosols. RRTMG also includes a statistical technique for representing small-scale cloud variability, such as cloud fraction and the vertical overlap of clouds, which has been shown to improve cloud radiative forcing in global models. This development approach has provided a direct link from observations to the enhanced radiative transfer provided by RRTMG for application to GCMs. Recent comparison of existing climate model radiation codes with high resolution models has documented the improved radiative forcing capability provided by RRTMG, especially at the surface, relative to other GCM radiation models. Due to its high accuracy, its connection to observations, and its computational efficiency, RRTMG has been implemented operationally in many national and international dynamical models to provide validated radiative transfer for improving weather forecasts and enhancing the prediction of global climate change.

    2013-01-01

    Stochastic biomathematical models are becoming increasingly important as new light is shed on the role of noise in living systems. In certain biological systems, stochastic effects may even enhance a signal, thus providing a biological motivation for the noise observed in living systems. Recent advances in stochastic analysis and increasing computing power facilitate the analysis of more biophysically realistic models, and this book provides researchers in computational neuroscience and stochastic systems with an overview of recent developments. Key concepts are developed in chapters written by experts in their respective fields. Topics include: one-dimensional homogeneous diffusions and their boundary behavior, large deviation theory and its application in stochastic neurobiological models, a review of mathematical methods for stochastic neuronal integrate-and-fire models, stochastic partial differential equation models in neurobiology, and stochastic modeling of spreading cortical depression.

    2016-05-12

    This paper introduces the sensor-networked IoT model as a prototype to support the design of Body Area Network (BAN) applications for healthcare. Using the model, we analyze the synergistic effect of the functional requirements (data collection from the human body and transferring it to the top level) and non-functional requirements (trade-offs between energy-security-environmental factors, treated as Quality-of-Service (QoS)). We use feature models to represent the requirements at the earliest stage for the analysis and describe a model-driven methodology to design the possible BAN applications. Firstly, we specify the requirements as the problem domain (PD) variability model for the BAN applications. Next, we introduce the generative technology (meta-programming as the solution domain (SD)) and the mapping procedure to map the PD feature-based variability model onto the SD feature model. Finally, we create an executable meta-specification that represents the BAN functionality to describe the variability of the problem domain though transformations. The meta-specification (along with the meta-language processor) is a software generator for multiple BAN-oriented applications. We validate the methodology with experiments and a case study to generate a family of programs for the BAN sensor controllers. This enables to obtain the adequate measure of QoS efficiently through the interactive adjustment of the meta-parameter values and re-generation process for the concrete BAN application.

    2018-01-01

    Full Text Available The rapid development of mobile health technology (m-Health provides unprecedented opportunities for improving health services. As the bridge between doctors and patients, mobile health applications enable patients to communicate with doctors through their smartphones, which is becoming more and more popular among people. To evaluate the influence of m-Health applications on the medical service market, we propose a medical service equilibrium model. The model can balance the supply of doctors and demand of patients and reflect possible options for both doctors and patients with or without m-Health applications in the medical service market. In the meantime, we analyze the behavior of patients and the activities of doctors to minimize patients’ full costs of healthcare and doctors’ futility. Then, we provide a resolution algorithm through mathematical reasoning. Lastly, based on artificially generated dataset, experiments are conducted to evaluate the medical services of m-Health applications.

    In order to make on-line risk monitoring application of Probabilistic Risk Assessment more complete and realistic, a special attention need to be dedicated to initiating events modeling. Two different issues are of special importance: one is how to model initiating events frequency according to current plant configuration (equipment alignment and out of service status) and operating condition (weather and various activities), and the second is how to preserve dependencies between initiating events model and rest of PRA model. First, the paper will discuss how initiating events can be treated in on-line risk monitoring application. Second, practical example of initiating events modeling in EPRI's Equipment Out of Service on-line monitoring tool will be presented. Gains from application and possible improvements will be discussed in conclusion. (author)

  3. Conflict and governability in Northern Uganda: Possibilities and limits of mato oput reconciliation rituals

    2009-10-01

    Full Text Available The war that broke out in Northern Uganda in 1986 – one of the most forgotten wars of our times – was the result of a long North-South conflict in the country, and has caused the displacement of 2 million people, the deaths of some 100,000 citizens and the kidnapping of 40,000 children by the Lord’s Resistance Army (LRA guerrilla. Repeated attempts by civil society (particularly by religious and traditional leaders to stop the conflict through negotiation has ended, time after time, in failures that have led to new waves of violence, most of them directed against the civil population. In this context, the traditional culture of the Acholi people has played a paramount role, and has backed several reconciliation initiatives. The most successful one was the amnesty law which, since 2002, has succeeded in reincorporating more than 12,000 people from the LRA. However, the use of traditional peace processes, particularly the mato oput, clashes with a reality that is unduly complicated by the thousands of murders that have been committed, sometimes by minors who have been forced to kill. The intervention of the International Criminal Court in The Hague since 2004 has not produced a very favourable response among the Acholi society, which views this court more as an obstacle than as a means to help bring this tragedy to an end. The dilemmas created by conflicts of interest between peace and justice, and the attempts to strengthen the role of traditional leaders to reincorporate combatants returning from war into society are just some of the underlying issues in this conflict which has, furthermore, an international dimension, as it has now affected four African countries.

  4. The Leaky Dielectric Model as a Weak Electrolyte Limit of an Electrodiffusion Model

    2017-11-01

    The Taylor-Melcher (TM) model is the standard model for the electrohydrodynamics of poorly conducting leaky dielectric fluids under an electric field. The TM model treats the fluid as an ohmic conductor, without modeling ion dynamics. On the other hand, electrodiffusion models, which have been successful in describing electokinetic phenomena, incorporates ionic concentration dynamics. Mathematical reconciliation between electrodiffusion and the TM models has been a major issue for electrohydrodynamic theory. Here, we derive the TM model from an electrodiffusion model where we explicitly model the electrochemistry of ion dissociation. We introduce salt dissociation reaction in the bulk and take the limit of weak salt dissociation (corresponding to poor conductors in the TM model.) Assuming small Debye length we derive the TM model with or without the surface charge advection term depending upon the scaling of relevant dimensionless parameters. Our analysis also gives a description of the ionic concentration distribution within the Debye layer, which hints at possible scenarios for electrohydrodynamic singularity formation. In our analysis we also allow for a jump in voltage across the liquid interface which causes a drifting velocity for a liquid drop under an electric field.

    Source noise affects the security of continuous-variable quantum key distribution (CV QKD) and is difficult to analyze. We propose a model to characterize Gaussian source noise through introducing a neutral party (Fred) who induces the noise with a general unitary transformation. Without knowing Fred's exact state, we derive the security bounds for both reverse and direct reconciliations and show that the bound for reverse reconciliation is tight.

    Software services offer the opportunity to use a component-based approach for the design of applications. However, this needs a deeper understanding of how to develop service-based applications in a systematic manner, and of the set of properties that need to be included in the 'design model'. We have used a realistic application to explore systematically how service-based designs can be created and described. We first identified the key properties of an SOA (service oriented architecture) and then undertook a single-case case study to explore its use in the development of a design for a large-scale application in energy engineering, modelling this with existing notations wherever possible. We evaluated the resulting design model using two walkthroughs with both domain and application experts. We were able to successfully develop a design model around the ten properties identified, and to describe it by adapting existing design notations. A component-based approach to designing such systems does appear to be feasible. However, it needs the assistance of a more integrated set of notations for describing the resulting design model.

  9. Application of postured human model for SAR measurements

    2013-07-01

    In the last two decades, the increasing number of electronic devices used in day-to-day life led to a growing interest in the study of the electromagnetic field interaction with biological tissues. The design of medical devices and wireless communication devices such as mobile phones benefits a lot from the bio-electromagnetic simulations in which digital human models are used. The digital human models currently available have an upright position which limits the research activities in realistic scenarios, where postured human bodies must be considered. For this reason, a software application called "BodyFlex for CST STUDIO SUITE" was developed. In its current version, this application can deform the voxel-based human model named HUGO (Dipp GmbH, 2010) to allow the generation of common postures that people use in normal life, ensuring the continuity of tissues and conserving the mass to an acceptable level. This paper describes the enhancement of the "BodyFlex" application, which is related to the movements of the forearm and the wrist of a digital human model. One of the electromagnetic applications in which the forearm and the wrist movement of a voxel based human model has a significant meaning is the measurement of the specific absorption rate (SAR) when a model is exposed to a radio frequency electromagnetic field produced by a mobile phone. Current SAR measurements of the exposure from mobile phones are performed with the SAM (Specific Anthropomorphic Mannequin) phantom which is filled with a dispersive but homogeneous material. We are interested what happens with the SAR values if a realistic inhomogeneous human model is used. To this aim, two human models, a homogeneous and an inhomogeneous one, in two simulation scenarios are used, in order to examine and observe the differences in the results for the SAR values.

This application notes provides a brief tutorial on the basic devices (branches, bus shunts, transformers and generators) found in power grids. The focus is on the features supported and assumptions made by the Xyce models for power grid elements. It then provides a detailed explanation, including working Xyce netlists, for simulating some simple power grid examples such as the IEEE 14-bus test case.

  11. Joint Data Assimilation and Parameter Calibration in on-line groundwater modelling using Sequential Monte Carlo techniques

    Ramgraber, M.; Schirmer, M.

    2017-12-01

    As computational power grows and wireless sensor networks find their way into common practice, it becomes increasingly feasible to pursue on-line numerical groundwater modelling. The reconciliation of model predictions with sensor measurements often necessitates the application of Sequential Monte Carlo (SMC) techniques, most prominently represented by the Ensemble Kalman Filter. In the pursuit of on-line predictions it seems advantageous to transcend the scope of pure data assimilation and incorporate on-line parameter calibration as well. Unfortunately, the interplay between shifting model parameters and transient states is non-trivial. Several recent publications (e.g. Chopin et al., 2013, Kantas et al., 2015) in the field of statistics discuss potential algorithms addressing this issue. However, most of these are computationally intractable for on-line application. In this study, we investigate to what extent compromises between mathematical rigour and computational restrictions can be made within the framework of on-line numerical modelling of groundwater. Preliminary studies are conducted in a synthetic setting, with the goal of transferring the conclusions drawn into application in a real-world setting. To this end, a wireless sensor network has been established in the valley aquifer around Fehraltorf, characterized by a highly dynamic groundwater system and located about 20 km to the East of Zürich, Switzerland. By providing continuous probabilistic estimates of the state and parameter distribution, a steady base for branched-off predictive scenario modelling could be established, providing water authorities with advanced tools for assessing the impact of groundwater management practices.

    2017-06-01

    Participatory research (PR) trials aim to achieve the dual, and at times competing, demands of producing an intervention and research process that address community perspectives and priorities, while establishing intervention effectiveness. To identify research and community priorities that must be reconciled in the areas of collaborative processes, study design and aim and study implementation quality in order to successfully conduct a participatory trial. We describe how this reconciliation was approached in the smoking prevention participatory trial Padres Informados/Jovenes Preparados (Informed Parents/Prepared Youth) and evaluate the success of our reconciled priorities. Data sources to evaluate success of the reconciliations included a survey of all partners regarding collaborative group processes, intervention participant recruitment and attendance and surveys of enrolled study participants assessing intervention outcomes. While we successfully achieved our reconciled collaborative processes and implementation quality goals, we did not achieve our reconciled goals in study aim and design. Due in part to the randomized wait-list control group design chosen in the reconciliation process, we were not able to demonstrate overall efficacy of the intervention or offer timely services to families in need of support. Achieving the goals of participatory trials is challenging but may yield community and research benefits. Innovative research designs are needed to better support the complex goals of participatory trials. © The Author 2017. Published by Oxford University Press. All rights reserved.

  18. The hard-core model on random graphs revisited

    International Nuclear Information System (INIS)

    Barbier, Jean; Krzakala, Florent; Zhang, Pan; Zdeborová, Lenka

    2013-01-01

    We revisit the classical hard-core model, also known as independent set and dual to vertex cover problem, where one puts particles with a first-neighbor hard-core repulsion on the vertices of a random graph. Although the case of random graphs with small and very large average degrees respectively are quite well understood, they yield qualitatively different results and our aim here is to reconciliate these two cases. We revisit results that can be obtained using the (heuristic) cavity method and show that it provides a closed-form conjecture for the exact density of the densest packing on random regular graphs with degree K ≥ 20, and that for K > 16 the nature of the phase transition is the same as for large K. This also shows that the hard-code model is the simplest mean-field lattice model for structural glasses and jamming

    Full Text Available Si aujourd’hui les Tribunaux pénaux internationaux pour l’ex-Yougoslavie et pour le Rwanda affirment qu’ils ont pour objectif de favoriser la restauration de la paix, cette mission puise pourtant ses racines dans une réglementation des comportements dans la guerre. Cette généalogie révèle un changement de mission du droit pénal international qui, associant progressivement justice et paix, a conduit récemment à y adjoindre la « réconciliation nationale ». Sans être définie, la « réconciliation nationale » va s’introduire dans le vocable des juges internationaux. Ainsi, lors de la détermination de la peine, les juges vont considérer que les efforts de l’accusé en faveur de la réconciliation nationale est un élément susceptible de réduire la peine au titre des circonstances atténuantes. A partir d’une analyse de l’ensemble des décisions des deux Tribunaux pénaux internationaux, cet article analyse sens et enjeux de l’appropriation de la « réconciliation nationale » par la justice pénale internationale saisie par des impératifs collectifs.Although the international criminal courts for the Former Yugoslavia and for Rwanda claim that their goal is to contribute to the restoration and the maintenance of peace, their mission originates in the laws of war. This genealogy reveals a shift in international criminal law’s missions. Combining « justice » and « peace », the international judges have added the notion of « national reconciliation » to their vocabulary without defining it. Thus to give a « fair sentence » judges are willing to consider the defendant’s efforts in favor of national reconciliation among the elements that they take into account as mitigating factors. Analyzing the judgments of the international criminal tribunal for the former Yugoslavia and for the Rwanda, this article explores what is at stake when international criminal justice is faced with social

    2016-01-01

    With the rapid accumulation of biological datasets, machine learning methods designed to automate data analysis are urgently needed. In recent years, so-called topic models that originated from the field of natural language processing have been receiving much attention in bioinformatics because of their interpretability. Our aim was to review the application and development of topic models for bioinformatics. This paper starts with the description of a topic model, with a focus on the understanding of topic modeling. A general outline is provided on how to build an application in a topic model and how to develop a topic model. Meanwhile, the literature on application of topic models to biological data was searched and analyzed in depth. According to the types of models and the analogy between the concept of document-topic-word and a biological object (as well as the tasks of a topic model), we categorized the related studies and provided an outlook on the use of topic models for the development of bioinformatics applications. Topic modeling is a useful method (in contrast to the traditional means of data reduction in bioinformatics) and enhances researchers' ability to interpret biological information. Nevertheless, due to the lack of topic models optimized for specific biological data, the studies on topic modeling in biological data still have a long and challenging road ahead. We believe that topic models are a promising method for various applications in bioinformatics research.

    The value of systems science modelling methods in the health sector is increasingly being recognised. Of particular promise is the potential of these methods to improve operational aspects of healthcare capacity and delivery, analyse policy options for health system reform and guide investments to address complex public health problems. Because it lends itself to a participatory approach, system dynamics modelling has been a particularly appealing method that aims to align stakeholder understanding of the underlying causes of a problem and achieve consensus for action. The aim of this review is to determine the effectiveness of system dynamics modelling for health policy, and explore the range and nature of its application. A systematic search was conducted to identify articles published up to April 2015 from the PubMed, Web of Knowledge, Embase, ScienceDirect and Google Scholar databases. The grey literature was also searched. Papers eligible for inclusion were those that described applications of system dynamics modelling to support health policy at any level of government. Six papers were identified, comprising eight case studies of the application of system dynamics modelling to support health policy. No analytic studies were found that examined the effectiveness of this type of modelling. Only three examples engaged multidisciplinary stakeholders in collective model building. Stakeholder participation in model building reportedly facilitated development of a common 'mental map' of the health problem, resulting in consensus about optimal policy strategy and garnering support for collaborative action. The paucity of relevant papers indicates that, although the volume of descriptive literature advocating the value of system dynamics modelling is considerable, its practical application to inform health policy making is yet to be routinely applied and rigorously evaluated. Advances in software are allowing the participatory model building approach to be extended to

    The proposal to use active thermography in medical diagnostics is promising in some applications concerning investigation of directly accessible parts of the human body. The combination of dynamic thermograms with thermal models of investigated structures gives attractive possibility to make internal structure reconstruction basing on different thermal properties of biological tissues. Measurements of temperature distribution synchronized with external light excitation allow registration of dynamic changes of local temperature dependent on heat exchange conditions. Preliminary results of active thermography applications in medicine are discussed. For skin and under- skin tissues an equivalent thermal model may be determined. For the assumed model its effective parameters may be reconstructed basing on the results of transient thermal processes. For known thermal diffusivity and conductivity of specific tissues the local thickness of a two or three layer structure may be calculated. Results of some medical cases as well as reference data of in vivo study on animals are presented. The method was also applied to evaluate the state of the human heart during the open chest cardio-surgical interventions. Reference studies of evoked heart infarct in pigs are referred, too. We see the proposed new in medical applications technique as a promising diagnostic tool. It is a fully non-invasive, clean, handy, fast and affordable method giving not only qualitative view of investigated surfaces but also an objective quantitative measurement result, accurate enough for many applications including fast screening of affected tissues.

    Current Web applications embed sophisticated user interfaces and business logic. The original interaction paradigm of the Web based on static content pages that are browsed by hyperlinks is, therefore, not valid anymore. In this paper, we advocate a paradigm shift for browsers and Web applications, that improves the management of user interaction and browsing history. Pages are replaced by States as basic navigation nodes, and Back/Forward navigation along the browsing history is replaced by a full-fledged interactive application paradigm, supporting transactions at the interface level and featuring Undo/Redo capabilities. This new paradigm offers a safer and more precise interaction model, protecting the user from unexpected behaviours of the applications and the browser.

    Watershed water environment pollution model is the important tool for studying watershed environmental problems. Through the quantitative description of the complicated pollution processes of whole watershed system and its parts, the model can identify the main sources and migration pathways of pollutants, estimate the pollutant loadings, and evaluate their impacts on water environment, providing a basis for watershed planning and management. This paper reviewed the watershed water environment models widely applied at home and abroad, with the focuses on the models of pollutants loading (GWLF and PLOAD), water quality of received water bodies (QUAL2E and WASP), and the watershed models integrated pollutant loadings and water quality (HSPF, SWAT, AGNPS, AnnAGNPS, and SWMM), and introduced the structures, principles, and main characteristics as well as the limitations in practical applications of these models. The other models of water quality (CE-QUAL-W2, EFDC, and AQUATOX) and watershed models (GLEAMS and MIKE SHE) were also briefly introduced. Through the case analysis on the applications of single model and integrated models, the development trend and application prospect of the watershed water environment pollution models were discussed.

    Over the last 30 years statistical algorithms have been developed to analyse datasets that have a hierarchical/multilevel structure. Particularly within developmental and educational psychology these techniques have become common where the sample has an obvious hierarchical structure, like pupils nested within a classroom. We describe two areas beyond the basic applications of multilevel modelling that are important to psychology: modelling the covariance structure in longitudinal designs and using generalized linear multilevel modelling as an alternative to methods from signal detection theory (SDT). Detailed code for all analyses is described using packages for the freeware R.

    Medication reconciliation (MedRec) has been a mandated or recommended activity in Canada, the USA and the UK for nearly 10 years. Accreditation bodies in North America will soon require MedRec for every admission, transfer and discharge of every patient. Studies of MedRec have revealed unintentional discrepancies in prescriptions but no clear evidence that clinically important outcomes are improved, leading to widely variable practices. Our objective was to apply process mapping methodology to MedRec to clarify current processes and resource usage, identify potential efficiencies and gaps in care, and make recommendations for improvement in the light of current literature evidence of effectiveness. Process engineers observed and recorded all MedRec activities at 3 academic teaching hospitals, from initial emergency department triage to patient discharge, for general internal medicine patients. Process maps were validated with frontline staff, then with the study team, managers and patient safety leads to summarise current problems and discuss solutions. Across all of the 3 hospitals, 5 general problem themes were identified: lack of use of all available medication sources, duplication of effort creating inefficiency, lack of timeliness of completion of the Best Possible Medication History, lack of standardisation of the MedRec process, and suboptimal communication of MedRec issues between physicians, pharmacists and nurses. MedRec as practised in this environment requires improvements in quality, timeliness, consistency and dissemination. Further research exploring efficient use of resources, in terms of personnel and costs, is required. Published by the BMJ Publishing Group Limited.

    2012-01-01

    The CERN Unified Industrial Control Systems framework (UNICOS) is a software generation methodology and a collection of development tools that standardizes the design of industrial control applications. A Software Factory, named the UNICOS Application Builder (UAB), was introduced to ease extensibility and maintenance of the framework, introducing a stable meta-model, a set of platform-independent models and platform-specific configurations against which code generation plug-ins and configuration generation plug-ins can be written. Such plug-ins currently target PLC programming environments (Schneider and SIEMENS PLCs) as well as SIEMENS WinCC Open Architecture SCADA (previously known as ETM PVSS) but are being expanded to cover more and more aspects of process control systems. We present what constitutes the UNICOS meta-model and the models in use, how these models can be used to capture knowledge about industrial control systems and how this knowledge can be used to generate both code and configuration for a variety of target usages.

    Modeling of gas pipeline usually considers that the gas flow is isothermal (or adiabatic) and that pressure changes occur instantaneously (quasi steady state approach). However, these assumptions are not valid in many important transient applications (changes of inlet and outlet flows/pressures, starting and stopping of compressors, changes of controller set points, among others). Besides, the gas properties are likely to depend simultaneously on the pipe position and on the operation time. For this reason, a mathematical model is presented and implemented in this paper in order to describe the gas flow in pipeline when pressure and temperature transients cannot be neglected. The model is used afterwards as a tool for reconciliation of available measured data. (author)

    One of the challenges for characterizing and modeling realistic multimedia applications is the lack of access to source codes. On-chip performance counters effectively resolve this problem by monitoring run-time behaviors at the instruction-level. This paper presents a novel technique of characterizing and modeling workloads at the instruction level for realistic multimedia applications using hardware performance counters. A variety of instruction counts are collected from some multimedia applications, such as RealPlayer, GSM Vocoder, MPEG encoder/decoder, and speech synthesizer. These instruction counts can be used to form a set of abstract characteristic parameters directly related to a processor`s architectural features. Based on microprocessor architectural constraints and these calculated abstract parameters, the architectural performance bottleneck for a specific application can be estimated. Meanwhile, the bottleneck estimation can provide suggestions about viable architectural/functional improvement for certain workloads. The biggest advantage of this new characterization technique is a better understanding of processor utilization efficiency and architectural bottleneck for each application. This technique also provides predictive insight of future architectural enhancements and their affect on current codes. In this paper the authors also attempt to model architectural effect on processor utilization without memory influence. They derive formulas for calculating CPI{sub 0}, CPI without memory effect, and they quantify utilization of architectural parameters. These equations are architecturally diagnostic and predictive in nature. Results provide promise in code characterization, and empirical/analytical modeling.

    2013-03-01

    In this paper, we present a model for application distribution and related security attacks in dense vehicular ad hoc networks (VANET) and sparse VANET which forms a delay tolerant network (DTN). We study the vulnerabilities of VANET to evaluate the attack scenarios and introduce a new attacker`s model as an extension to the work done in [6]. Then a VANET model has been proposed that supports the application distribution through proxy app stores on top of mobile platforms installed in vehicles. The steps of application distribution have been studied in detail. We have identified key attacks (e.g. malware, spamming and phishing, software attack and threat to location privacy) for dense VANET and two attack scenarios for sparse VANET. It has been shown that attacks can be launched by distributing malicious applications and injecting malicious codes to On Board Unit (OBU) by exploiting OBU software security holes. Consequences of such security attacks have been described. Finally, countermeasures including the concepts of sandbox have also been presented in depth.

    Hanford's Transuranic (TRU) Program is responsible for certifying contact-handled (CH) TRU waste and shipping the certified waste to the Waste Isolation Pilot Plant (WIPP). Hanford's CH TRU waste includes material that is in retrievable storage as well as above ground storage, and newly generated waste. Certifying a typical container entails retrieving and then characterizing it (Real-Time Radiography, Non-Destructive Assay, and Head Space Gas Sampling), validating records (data review and reconciliation), and designating the container for a payload. The certified payload is then shipped to WIPP. Systems modeling and analysis techniques were applied to Hanford's TRU Program to help streamline the certification process and increase shipping rates

  10. Application of autoregressive moving average model in reactor noise analysis

    International Nuclear Information System (INIS)

    Tran Dinh Tri

    1993-01-01

    The application of an autoregressive (AR) model to estimating noise measurements has achieved many successes in reactor noise analysis in the last ten years. The physical processes that take place in the nuclear reactor, however, are described by an autoregressive moving average (ARMA) model rather than by an AR model. Consequently more correct results could be obtained by applying the ARMA model instead of the AR model to reactor noise analysis. In this paper the system of the generalised Yule-Walker equations is derived from the equation of an ARMA model, then a method for its solution is given. Numerical results show the applications of the method proposed. (author)

    2015-01-01

    The use of modeling has become widespread in water resources engineering and science to study rivers, lakes, estuaries, and coastal regions. For example, computer models are commonly used to forecast anthropogenic effects on the environment, and to help provide advanced mitigation measures against catastrophic events such as natural and dam-break floods. Linking hydraulic models to vegetation and habitat models has expanded their use in multidisciplinary applications to the riparian corridor. Implementation of these models in software packages on personal desktop computers has made them accessible to the general engineering community, and their use has been popularized by the need of minimal training due to intuitive graphical user interface front ends. Models are, however, complex and nontrivial, to the extent that even common terminology is sometimes ambiguous and often applied incorrectly. In fact, many efforts are currently under way in order to standardize terminology and offer guidelines for good practice, but none has yet reached unanimous acceptance. This chapter provides a view of the elements involved in modeling surface flows for the application in environmental water resources engineering. It presents the concepts and steps necessary for rational model development and use by starting with the exploration of the ideas involved in defining a model. Tangible form of those ideas is provided by the development of a mathematical and corresponding numerical hydraulic model, which is given with a substantial amount of detail. The issues of model deployment in a practical and productive work environment are also addressed. The chapter ends by presenting a few model applications highlighting the need for good quality control in model validation.

    Science.gov (United States)

    Zhao, Zhibiao

    2011-06-01

    We address the nonparametric model validation problem for hidden Markov models with partially observable variables and hidden states. We achieve this goal by constructing a nonparametric simultaneous confidence envelope for transition density function of the observable variables and checking whether the parametric density estimate is contained within such an envelope. Our specification test procedure is motivated by a functional connection between the transition density of the observable variables and the Markov transition kernel of the hidden states. Our approach is applicable for continuous time diffusion models, stochastic volatility models, nonlinear time series models, and models with market microstructure noise.

    2017-11-01

    This paper presents a developed java android application for KMV-Merton model in predicting the defaut rate of a firm. Predicting default rate is essential in the risk management area as default risk can be immediately transmitted from one entity to another entity. This is the reason default risk is known as a global risk. Although there are several efforts, instruments and methods used to manage the risk, it is said to be insufficient. To the best of our knowledge, there has been limited innovation in developing the default risk mathematical model into a mobile application. Therefore, through this study, default risk is predicted quantitatively using the KMV-Merton model. The KMV-Merton model has been integrated in the form of java program using the Android Studio Software. The developed java android application is tested by predicting the levels of default risk of the three different rated companies. It is found that the levels of default risk are equivalent to the ratings of the respective companies. This shows that the default rate predicted by the KMV-Merton model using the developed java android application can be a significant tool to the risk mangement field. The developed java android application grants users an alternative to predict level of default risk within less procedure.

  5. Applications of the k – ω Model in Stellar Evolutionary Models

    Energy Technology Data Exchange (ETDEWEB)

    Li, Yan, E-mail: ly@ynao.ac.cn [Yunnan Observatories, Chinese Academy of Sciences, Kunming 650216 (China)

    2017-05-20

    The k – ω model for turbulence was first proposed by Kolmogorov. A new k – ω model for stellar convection was developed by Li, which could reasonably describe turbulent convection not only in the convectively unstable zone, but also in the overshooting regions. We revised the k – ω model by improving several model assumptions (including the macro-length of turbulence, convective heat flux, and turbulent mixing diffusivity, etc.), making it applicable not only for convective envelopes, but also for convective cores. Eight parameters are introduced in the revised k – ω model. It should be noted that the Reynolds stress (turbulent pressure) is neglected in the equation of hydrostatic support. We applied it into solar models and 5 M {sub ⊙} stellar models to calibrate the eight model parameters, as well as to investigate the effects of the convective overshooting on the Sun and intermediate mass stellar models.

  6. Stochastic linear hybrid systems: Modeling, estimation, and application

    Science.gov (United States)

    Seah, Chze Eng

    Hybrid systems are dynamical systems which have interacting continuous state and discrete state (or mode). Accurate modeling and state estimation of hybrid systems are important in many applications. We propose a hybrid system model, known as the Stochastic Linear Hybrid System (SLHS), to describe hybrid systems with stochastic linear system dynamics in each mode and stochastic continuous-state-dependent mode transitions. We then develop a hybrid estimation algorithm, called the State-Dependent-Transition Hybrid Estimation (SDTHE) algorithm, to estimate the continuous state and discrete state of the SLHS from noisy measurements. It is shown that the SDTHE algorithm is more accurate or more computationally efficient than existing hybrid estimation algorithms. Next, we develop a performance analysis algorithm to evaluate the performance of the SDTHE algorithm in a given operating scenario. We also investigate sufficient conditions for the stability of the SDTHE algorithm. The proposed SLHS model and SDTHE algorithm are illustrated to be useful in several applications. In Air Traffic Control (ATC), to facilitate implementations of new efficient operational concepts, accurate modeling and estimation of aircraft trajectories are needed. In ATC, an aircraft's trajectory can be divided into a number of flight modes. Furthermore, as the aircraft is required to follow a given flight plan or clearance, its flight mode transitions are dependent of its continuous state. However, the flight mode transitions are also stochastic due to navigation uncertainties or unknown pilot intents. Thus, we develop an aircraft dynamics model in ATC based on the SLHS. The SDTHE algorithm is then used in aircraft tracking applications to estimate the positions/velocities of aircraft and their flight modes accurately. Next, we develop an aircraft conformance monitoring algorithm to detect any deviations of aircraft trajectories in ATC that might compromise safety. In this application, the SLHS

    Vuorinen, Anna; Bellion, Phillip; Beilstein, Paul

    2017-11-01

    Evaluation of the genotoxic potential of food and feed ingredients is required in the development of new substances and for their registration. In addition to in vitro and in vivo assays, in silico tools such as expert alert-based and statistical models can be used for data generation. These in silico models are commonly used among the pharmaceutical industry, whereas the food industry has not widely adopted them. In this study, the applicability of in silico tools for predicting genotoxicity was evaluated, with a focus on bacterial mutagenicity, in vitro and in vivo chromosome damage assays. For this purpose, a test set of 27 food and feed ingredients including vitamins, carotenoids, and nutraceuticals with experimental genotoxicity data was constructed from proprietary data. This dataset was run through multiple models and the model applicability was analyzed. The compounds were generally within the applicability domain of the models and the models predicted the compounds correctly in most of the cases. Although the regulatory acceptance of in silico tools as single data source is still limited, the models are applicable and can be used in the safety evaluation of food and feed ingredients.

  8. Canadian Whole-Farm Model Holos - Development, Stakeholder Involvement, and Model Application

    Science.gov (United States)

    Kroebel, R.; Janzen, H.; Beauchemin, K. A.

    2017-12-01

    Agriculture and Agri-Food Canada's Holos model, based mostly on emission factors, aims to explore the effect of management on Canadian whole-farm greenhouse gas emissions. The model includes 27 commonly grown annual and perennial crops, summer fallow, grassland, and 8 types of tree plantings, along with beef, dairy, sheep, swine and other livestock or poultry operations. Model outputs encompass net emissions of CO2, CH4, and N2O (in CO2 equivalents), calculated for various farm components. Where possible, algorithms are drawn from peer-reviewed publications. For consistency, Holos is aligned with the Canadian sustainability indicator and national greenhouse gas inventory objectives. Although primarily an exploratory tool for research, the model's design makes it accessible and instructive also to agricultural producers, educators, and policy makers. Model development, therefore, proceeds iteratively, with extensive stakeholder feedback from training sessions or annual workshops. To make the model accessible to diverse users, the team developed a multi-layered interface, with general farming scenarios for general use, but giving access to detailed coefficients and assumptions to researchers. The model relies on extensive climate, soil, and agronomic databases to populate regionally-applicable default values thereby minimizing keyboard entries. In an initial application, the model was used to assess greenhouse gas emissions from the Canadian beef production system; it showed that enteric methane accounted for 63% of total GHG emissions and that 84% of emissions originated from the cow-calf herd. The model further showed that GHG emission intensity per kg beef, nationally, declined by 14% from 1981 to 2011, owing to gains in production efficiency. Holos is now being used to consider further potential advances through improved rations or other management options. We are now aiming to expand into questions of grazing management, and are developing a novel carbon

  12. Distributionally Robust Return-Risk Optimization Models and Their Applications

    Directory of Open Access Journals (Sweden)

    Li Yang

    2014-01-01

    Full Text Available Based on the risk control of conditional value-at-risk, distributionally robust return-risk optimization models with box constraints of random vector are proposed. They describe uncertainty in both the distribution form and moments (mean and covariance matrix of random vector. It is difficult to solve them directly. Using the conic duality theory and the minimax theorem, the models are reformulated as semidefinite programming problems, which can be solved by interior point algorithms in polynomial time. An important theoretical basis is therefore provided for applications of the models. Moreover, an application of the models to a practical example of portfolio selection is considered, and the example is evaluated using a historical data set of four stocks. Numerical results show that proposed methods are robust and the investment strategy is safe.

  13. Mission and Ethics in 1 Corinthians: Reconciliation, corporate solidarity and other-regard as missionary strategy in Paul

    Directory of Open Access Journals (Sweden)

    Jacobus Kok

    2012-06-01

    Full Text Available In this article the dynamic relationship between mission and ethics in contexts of conflict and change in the Corinthian correspondence was investigated, and the role Paul played as reconciling leader, examined. The early Christian writers like Paul wanted to instruct and shape communities of faith. Paul was especially concerned with the maintenance and growth of his congregations and also with the social and ethical boundaries between the community of faith and the ‘world’. In the article it was illustrated that within the Corinthian congregational context there existed several conflict situations, and that much of it was a result of diversity within the congregation. Diversity is a fact of life and reality of the church. In Paul’s vision for unity and reconciliation, and in his attempt to address the factionalism in the Corinthian congregation, he would in all cases, ground his practical solution in a theological identity construction. Paul focuses on corporate solidarity and unity and urges the congregation to find their fellow brothers and sisters in times of conflict by means of ethical reciprocity and other-regard, a matter in which he is also an example, typical of other philosophers of his time – but with a significant difference. At the end it becomes clear that Paul’s ethical advice has a missional dimension, in the sense that the conflict management should take place in such a way that God is honoured and that both Jews, Greeks and fellow believers will see that the way this community handles conflict, is different to the way the ‘world’ would do it, and that in the process, even more might be saved.

  14. Evaluating the power consumption of wireless sensor network applications using models.

    2013-03-13

    Power consumption is the main concern in developing Wireless Sensor Network (WSN) applications. Consequently, several strategies have been proposed for investigating the power consumption of this kind of application. These strategies can help to predict the WSN lifetime, provide recommendations to application developers and may optimize the energy consumed by the WSN applications. While measurement is a known and precise strategy for power consumption evaluation, it is very costly, tedious and may be unfeasible considering the (usual) large number of WSN nodes. Furthermore, due to the inherent dynamism of WSNs, the instrumentation required by measurement techniques makes difficult their use in several different scenarios. In this context, this paper presents an approach for evaluating the power consumption of WSN applications by using simulation models along with a set of tools to automate the proposed approach. Starting from a programming language code, we automatically generate consumption models used to predict the power consumption of WSN applications. In order to evaluate the proposed approach, we compare the results obtained by using the generated models against ones obtained by measurement.

    Spindler, A

    2014-06-15

    Although data reconciliation is intensely applied in process engineering, almost none of its powerful methods are employed for validation of operational data from wastewater treatment plants. This is partly due to some prerequisites that are difficult to meet including steady state, known variances of process variables and absence of gross errors. However, an algorithm can be derived from the classical approaches to data reconciliation that allows to find a comprehensive set of equations describing redundancy in the data when measured and unmeasured variables (flows and concentrations) are defined. This is a precondition for methods of data validation based on individual mass balances such as CUSUM charts. The procedure can also be applied to verify the necessity of existing or additional measurements with respect to the improvement of the data's redundancy. Results are given for a large wastewater treatment plant. The introduction aims at establishing a link between methods known from data reconciliation in process engineering and their application in wastewater treatment. Copyright © 2014 Elsevier Ltd.

    Critical care delivery is a complex, expensive, error prone, medical specialty and remains the focal point of major improvement efforts in healthcare delivery. Various modeling and simulation techniques offer unique opportunities to better understand the interactions between clinical physiology and care delivery. The novel insights gained from the systems perspective can then be used to develop and test new treatment strategies and make critical care delivery more efficient and effective. However, modeling and simulation applications in critical care remain underutilized. This article provides an overview of major computer-based simulation techniques as applied to critical care medicine. We provide three application examples of different simulation techniques, including a) pathophysiological model of acute lung injury, b) process modeling of critical care delivery, and c) an agent-based model to study interaction between pathophysiology and healthcare delivery.

    2018-04-01

    A river system is defined as a network of channels that drains different parts of a basin uniting downstream to form a common outflow. An application of various models found in literatures, to a river system having multiple upstream flows is not always straight forward, involves a lengthy procedure; and with non-availability of data sets model calibration and applications may become difficult. In the case of a river system the flow modeling can be simplified to a large extent if the channel network is replaced by an equivalent single channel. In the present work optimization model formulations based on equivalent flow and applications of the mixed integer programming based pre-emptive goal programming model in evaluating flood control alternatives for a real life river system in India are proposed to be covered in the study.

  19. Estimation of the applicability domain of kernel-based machine learning models for virtual screening

    2010-03-01

    Full Text Available Abstract Background The virtual screening of large compound databases is an important application of structural-activity relationship models. Due to the high structural diversity of these data sets, it is impossible for machine learning based QSAR models, which rely on a specific training set, to give reliable results for all compounds. Thus, it is important to consider the subset of the chemical space in which the model is applicable. The approaches to this problem that have been published so far mostly use vectorial descriptor representations to define this domain of applicability of the model. Unfortunately, these cannot be extended easily to structured kernel-based machine learning models. For this reason, we propose three approaches to estimate the domain of applicability of a kernel-based QSAR model. Results We evaluated three kernel-based applicability domain estimations using three different structured kernels on three virtual screening tasks. Each experiment consisted of the training of a kernel-based QSAR model using support vector regression and the ranking of a disjoint screening data set according to the predicted activity. For each prediction, the applicability of the model for the respective compound is quantitatively described using a score obtained by an applicability domain formulation. The suitability of the applicability domain estimation is evaluated by comparing the model performance on the subsets of the screening data sets obtained by different thresholds for the applicability scores. This comparison indicates that it is possible to separate the part of the chemspace, in which the model gives reliable predictions, from the part consisting of structures too dissimilar to the training set to apply the model successfully. A closer inspection reveals that the virtual screening performance of the model is considerably improved if half of the molecules, those with the lowest applicability scores, are omitted from the screening

    2013-08-01

    Theoretical models provide a framework for describing practice and integrating evidence into systematic research. There are few models that relate specifically to the provision of assistive technology in occupational therapy practice. The Human Activity Assistive Technology model is an enduring example that has continued to develop by integrating a social model of disability, concepts from occupational therapy theory and principles of assistive technology adoption and abandonment. This study first describes the core concepts of the Human Activity Assistive Technology model and reviews its development over three successive published versions. A review of the research literature reflects application of the model to clinical practice, study design, outcome measure selection and interpretation of results, particularly among occupational therapists. An evaluative framework is used to critique the adequacy of the Human Activity Assistive Technology model for practice and research, exploring attributes of clarity, simplicity, generality, accessibility and importance. Finally, recommendations are proposed for continued development of the model and research applications. Most of the existing research literature employs the Human Activity Assistive Technology model for background and study design; there is emerging evidence to support the core concepts as predictive factors. Although the concepts are generally simple, clear and applicable to occupational therapy practice and research, evolving terminology and outcomes become more complex with the conflation of integrated theories. The development of the Human Activity Assistive Technology model offers enhanced access and application for occupational therapists, but poses challenges to clarity among concepts. Suggestions are made for further development and applications of the model. © 2013 Occupational Therapy Australia.

  4. The reconciliation of an F-region irregularity model with sunspot-cycle variations in spread-F occurrence

    International Nuclear Information System (INIS)

    Singleton, D.G.

    1974-11-01

    A recently proposed means of combining models of ionospheric F-layer peak electron density and irregularity incremental electron density (ΔN) so as to simulate the global occurrence probability of the frequency spreading component of spread-F is discussed. This procedure is then used to model experimental spread-F occurrence results. It is found possible to readily simulate the sunspot-maximum results, independently of season, with only small adjustments to the amplitudes of the empirical expressions used to ΔN in the several latitude regimes. However, at sunspot minimum and for each season, the ΔN model requires modification in the equatorial and mid-latitude regions of high irregularity incidence, before successful simulations of the spread-F data can be obtained. These modifications, which include a broadening of the equatorial region and a polewards shift to the mid-latitude region with decreasing sunspot number, are discussed in detail. It is concluded that the scintillation data base, from which the original ΔN model derives, is not sufficiently representative with regard to sunspot number and magnetic index. The use of the spread-F adaptation of the ΔN model, as well as its original scintillation version, to rectify these failings of the ΔN model are also discussed. (author)

    The CERN Unified Industrial Control Systems framework (UNICOS) is a software generation methodology and a collection of development tools that standardizes the design of industrial control applications [1]. A Software Factory, named the UNICOS Application Builder (UAB) [2], was introduced to ease extensibility and maintenance of the framework, introducing a stable metamodel, a set of platformindependent models and platformspecific configurations against which code generation plugins and configuration generation plugins can be written. Such plugins currently target PLC programming environments (Schneider and SIEMENS PLCs) as well as SIEMENS WinCC Open Architecture SCADA (previously known as ETM PVSS) but are being expanded to cover more and more aspects of process control systems. We present what constitutes the UNICOS metamodel and the models in use, how these models can be used to capture knowledge about industrial control systems and how this knowledge can be leveraged to generate both code and configuratio...

    When facing complex requirements of city development, ever-growing spatial data, rapid development of geographical business and increasing business complexity, collaboration between multiple users and departments is needed urgently, however conventional GIS software (such as Client/Server model or Browser/Server model) are not support this well. Collaborative application is one of the good resolutions. Collaborative application has four main problems to resolve: consistency and co-edit conflict, real-time responsiveness, unconstrained operation, spatial data recoverability. In paper, application model called AMCM is put forward based on agent and multi-level cache. AMCM can be used in mixed network structure and supports distributed collaborative. Agent is an autonomous, interactive, initiative and reactive computing entity in a distributed environment. Agent has been used in many fields such as compute science and automation. Agent brings new methods for cooperation and the access for spatial data. Multi-level cache is a part of full data. It reduces the network load and improves the access and handle of spatial data, especially, in editing the spatial data. With agent technology, we make full use of its characteristics of intelligent for managing the cache and cooperative editing that brings a new method for distributed cooperation and improves the efficiency.

    2017-10-01

    Significant developments in longitudinal train simulation and an overview of the approaches to train models and modelling vehicle force inputs are firstly presented. The most important modelling task, that of the wagon connection, consisting of energy absorption devices such as draft gears and buffers, draw gear stiffness, coupler slack and structural stiffness is then presented. Detailed attention is given to the modelling approaches for friction wedge damped and polymer draft gears. A significant issue in longitudinal train dynamics is the modelling and calculation of the input forces - the co-dimensional problem. The need to push traction performances higher has led to research and improvement in the accuracy of traction modelling which is discussed. A co-simulation method that combines longitudinal train simulation, locomotive traction control and locomotive vehicle dynamics is presented. The modelling of other forces, braking propulsion resistance, curve drag and grade forces are also discussed. As extensions to conventional longitudinal train dynamics, lateral forces and coupler impacts are examined in regards to interaction with wagon lateral and vertical dynamics. Various applications of longitudinal train dynamics are then presented. As an alternative to the tradition single wagon mass approach to longitudinal train dynamics, an example incorporating fully detailed wagon dynamics is presented for a crash analysis problem. Further applications of starting traction, air braking, distributed power, energy analysis and tippler operation are also presented.

    Because prevailing atmospheric/troposcopic conditions greatly influence radio wave propagation above 10 GHz, the unguided propagation of microwaves in the neutral atmosphere can directly impact many vital applications in science and engineering. These include transmission of intelligence, and radar and radiometric applications used to probe the atmosphere, among others. Where most books address either one or the other, Microwave Propagation and Remote Sensing: Atmospheric Influences with Models and Applications melds coverage of these two subjects to help readers develop solutions to the problems they present. This reference offers a brief, elementary account of microwave propagation through the atmosphere and discusses radiometric applications in the microwave band used to characterize and model atmospheric constituents, which is also known as remote sensing.

    2012-04-16

    Smart Grid modernizes power grid by integrating digital and information technologies. Millions of smart meters, intelligent appliances and communication infrastructures are under deployment allowing advanced IT applications to be developed to secure and manage power grid operations. Demand response (DR) is one such emerging application to optimize electricity demand by curtailing/shifting power load when peak load occurs. Existing DR approaches are mostly based on static plans such as pricing policies and load shedding schedules. However, improvements to power management applications rely on data emanating from existing and new information sources with the growth of Smart Grid information space. In particular, dynamic DR algorithms depend on information from smart meters that report interval-based power consumption measurement, HVAC systems that monitor buildings heat and humidity, and even weather forecast services. In order for emerging Smart Grid applications to take advantage of the diverse data influx, extensible information integration is required. In this paper, we develop an integrated Smart Grid information model using Semantic Web techniques and present case studies of using semantic information for dynamic DR. We show the semantic model facilitates information integration and knowledge representation for developing the next generation Smart Grid applications.

  11. Wave model downscaling for coastal applications

    Valchev, Nikolay; Davidan, Georgi; Trifonova, Ekaterina; Andreeva, Nataliya

    2010-05-01

    Downscaling is a suitable technique for obtaining high-resolution estimates from relatively coarse-resolution global models. Dynamical and statistical downscaling has been applied to the multidecadal simulations of ocean waves. Even as large-scale variability might be plausibly estimated from these simulations, their value for the small scale applications such as design of coastal protection structures and coastal risk assessment is limited due to their relatively coarse spatial and temporal resolutions. Another advantage of the high resolution wave modeling is that it accounts for shallow water effects. Therefore, it can be used for both wave forecasting at specific coastal locations and engineering applications that require knowledge about extreme wave statistics at or near the coastal facilities. In the present study downscaling is applied to both ECMWF and NCEP/NCAR global reanalysis of atmospheric pressure over the Black Sea with 2.5 degrees spatial resolution. A simplified regional atmospheric model is employed for calculation of the surface wind field at 0.5 degrees resolution that serves as forcing for the wave models. Further, a high-resolution nested WAM/SWAN wave model suite of nested wave models is applied for spatial downscaling. It aims at resolving the wave conditions in a limited area at the close proximity to the shore. The pilot site is located in the northern part the Bulgarian Black Sea shore. The system involves the WAM wave model adapted for basin scale simulation at 0.5 degrees spatial resolution. The WAM output for significant wave height, mean wave period and mean angle of wave approach is used in terms of external boundary conditions for the SWAN wave model, which is set up for the western Black Sea shelf at 4km resolution. The same model set up on about 400m resolution is nested to the first SWAN run. In this case the SWAN 2D spectral output provides boundary conditions for the high-resolution model run. The models are implemented for a

    2017-02-01

    With the increasing data size in materials science, existing programming models no longer satisfy the application requirements. MapReduce is a programming model that enables the easy development of scalable parallel applications to process big data on cloud computing systems. However, this model does not directly support the processing of multiple related data, and the processing performance does not reflect the advantages of cloud computing. To enhance the capability of workflow applications in material data processing, we defined a programming model for material cloud applications that supports multiple different Map and Reduce functions running concurrently based on hybrid share-memory BSP called MaMR. An optimized data sharing strategy to supply the shared data to the different Map and Reduce stages was also designed. We added a new merge phase to MapReduce that can efficiently merge data from the map and reduce modules. Experiments showed that the model and framework present effective performance improvements compared to previous work.

  13. Current developments in soil organic matter modeling and the expansion of model applications: a review

    International Nuclear Information System (INIS)

    Campbell, Eleanor E; Paustian, Keith

    2015-01-01

    Soil organic matter (SOM) is an important natural resource. It is fundamental to soil and ecosystem functions across a wide range of scales, from site-specific soil fertility and water holding capacity to global biogeochemical cycling. It is also a highly complex material that is sensitive to direct and indirect human impacts. In SOM research, simulation models play an important role by providing a mathematical framework to integrate, examine, and test the understanding of SOM dynamics. Simulation models of SOM are also increasingly used in more ‘applied’ settings to evaluate human impacts on ecosystem function, and to manage SOM for greenhouse gas mitigation, improved soil health, and sustainable use as a natural resource. Within this context, there is a need to maintain a robust connection between scientific developments in SOM modeling approaches and SOM model applications. This need forms the basis of this review. In this review we first provide an overview of SOM modeling, focusing on SOM theory, data-model integration, and model development as evidenced by a quantitative review of SOM literature. Second, we present the landscape of SOM model applications, focusing on examples in climate change policy. We conclude by discussing five areas of recent developments in SOM modeling including: (1) microbial roles in SOM stabilization; (2) modeling SOM saturation kinetics; (3) temperature controls on decomposition; (4) SOM dynamics in deep soil layers; and (5) SOM representation in earth system models. Our aim is to comprehensively connect SOM model development to its applications, revealing knowledge gaps in need of focused interdisciplinary attention and exposing pitfalls that, if avoided, can lead to best use of SOM models to support policy initiatives and sustainable land management solutions.

    2014-12-01

    Full Text Available The paper presents functional modelling and its application for diagnosis in nuclear power plants. Functional modelling is defined and its relevance for coping with the complexity of diagnosis in large scale systems like nuclear plants is explained. The diagnosis task is analyzed and it is demonstrated that the levels of abstraction in models for diagnosis must reflect plant knowledge about goals and functions which is represented in functional modelling. Multilevel flow modelling (MFM, which is a method for functional modelling, is introduced briefly and illustrated with a cooling system example. The use of MFM for reasoning about causes and consequences is explained in detail and demonstrated using the reasoning tool, the MFMSuite. MFM applications in nuclear power systems are described by two examples: a PWR; and an FBR reactor. The PWR example show how MFM can be used to model and reason about operating modes. The FBR example illustrates how the modelling development effort can be managed by proper strategies including decomposition and reuse.

    The paper presents functional modelling and its application for diagnosis in nuclear power plants. Functional modelling is defined and its relevance for coping with the complexity of diagnosis in large scale systems like nuclear plants is explained. The diagnosis task is analyzed and it is demonstrated that the levels of abstraction in models for diagnosis must reflect plant knowledge about goals and functions which is represented in functional modelling.

    Full Text Available For Enterprise Resource Planning (ERP systems such as SAP R/3 or IBM SanFrancisco, the tailoring of reference models for customizing the ERP systems to specific organizational contexts is an established approach. In this paper, we present a methodology that uses such reference models as a starting point for a top-down integration of enterprise applications. The re-engineered models of legacy systems are individually linked via cross-mapping specifications to the forward-engineered reference model's specification. The actual linking of reference and legacy models is done with a methodology for connecting (new business objects with (old legacy systems.

It is well-known that optimal reconciliations in the unlabeled case may violate time-consistency and thus are not biologically feasible. Here we investigate the mathematical structure...... of the event labeled reconciliation problem with horizontal transfer. Results: We investigate the issue of time-consistency for the event-labeled version of the reconciliation problem, provide a convenient axiomatic framework, and derive a complete characterization of time-consistent reconciliations....... This characterization depends on certain weak conditions on the event-labeled gene trees that reflect conditions under which evolutionary events are observable at least in principle.

  5. Environmental Impacts of Large Scale Biochar Application Through Spatial Modeling

    Huber, I.; Archontoulis, S.

    2017-12-01

    In an effort to study the environmental (emissions, soil quality) and production (yield) impacts of biochar application at regional scales we coupled the APSIM-Biochar model with the pSIMS parallel platform. So far the majority of biochar research has been concentrated on lab to field studies to advance scientific knowledge. Regional scale assessments are highly needed to assist decision making. The overall objective of this simulation study was to identify areas in the USA that have the most gain environmentally from biochar's application, as well as areas which our model predicts a notable yield increase due to the addition of biochar. We present the modifications in both APSIM biochar and pSIMS components that were necessary to facilitate these large scale model runs across several regions in the United States at a resolution of 5 arcminutes. This study uses the AgMERRA global climate data set (1980-2010) and the Global Soil Dataset for Earth Systems modeling as a basis for creating its simulations, as well as local management operations for maize and soybean cropping systems and different biochar application rates. The regional scale simulation analysis is in progress. Preliminary results showed that the model predicts that high quality soils (particularly those common to Iowa cropping systems) do not receive much, if any, production benefit from biochar. However, soils with low soil organic matter ( 0.5%) do get a noteworthy yield increase of around 5-10% in the best cases. We also found N2O emissions to be spatial and temporal specific; increase in some areas and decrease in some other areas due to biochar application. In contrast, we found increases in soil organic carbon and plant available water in all soils (top 30 cm) due to biochar application. The magnitude of these increases (% change from the control) were larger in soil with low organic matter (below 1.5%) and smaller in soils with high organic matter (above 3%) and also dependent on biochar

  6. Continuum-Kinetic Models and Numerical Methods for Multiphase Applications

    Science.gov (United States)

    Nault, Isaac Michael

    This thesis presents a continuum-kinetic approach for modeling general problems in multiphase solid mechanics. In this context, a continuum model refers to any model, typically on the macro-scale, in which continuous state variables are used to capture the most important physics: conservation of mass, momentum, and energy. A kinetic model refers to any model, typically on the meso-scale, which captures the statistical motion and evolution of microscopic entitites. Multiphase phenomena usually involve non-negligible micro or meso-scopic effects at the interfaces between phases. The approach developed in the thesis attempts to combine the computational performance benefits of a continuum model with the physical accuracy of a kinetic model when applied to a multiphase problem. The approach is applied to modeling a single particle impact in Cold Spray, an engineering process that intimately involves the interaction of crystal grains with high-magnitude elastic waves. Such a situation could be classified a multiphase application due to the discrete nature of grains on the spatial scale of the problem. For this application, a hyper elasto-plastic model is solved by a finite volume method with approximate Riemann solver. The results of this model are compared for two types of plastic closure: a phenomenological macro-scale constitutive law, and a physics-based meso-scale Crystal Plasticity model.

    With the development of research on space environment and space science, how to develop network online computing environment of space weather, space environment and space physics models for Chinese scientific community is becoming more and more important in recent years. Currently, There are two software modes on space physics multi-model application integrated system (SPMAIS) such as C/S and B/S. the C/S mode which is traditional and stand-alone, demands a team or workshop from many disciplines and specialties to build their own multi-model application integrated system, that requires the client must be deployed in different physical regions when user visits the integrated system. Thus, this requirement brings two shortcomings: reducing the efficiency of researchers who use the models to compute; inconvenience of accessing the data. Therefore, it is necessary to create a shared network resource access environment which could help users to visit the computing resources of space physics models through the terminal quickly for conducting space science research and forecasting spatial environment. The SPMAIS develops high-performance, first-principles in B/S mode based on computational models of the space environment and uses these models to predict "Space Weather", to understand space mission data and to further our understanding of the solar system. the main goal of space physics multi-model application integration system (SPMAIS) is to provide an easily and convenient user-driven online models operating environment. up to now, the SPMAIS have contained dozens of space environment models , including international AP8/AE8 IGRF T96 models and solar proton prediction model geomagnetic transmission model etc. which are developed by Chinese scientists. another function of SPMAIS is to integrate space observation data sets which offers input data for models online high-speed computing.

    Stock, D.; Samanta, P.; Vesely, W.

    1994-06-01

    This report presents the development and application of component degradation modeling to analyze degradation effects on reliability and to identify aspects of maintenance practices that mitigate degradation and aging effects. Using continuous time Markov approaches, a component degradation model is discussed that includes information about degradation and maintenance. The component model commonly used in probabilistic risk assessments is a simple case of this general model. The parameters used in the general model have engineering interpretations and can be estimated using data and engineering experience. The generation of equations for specific models, the solution of these equations, and a methodology for estimating the needed parameters are all discussed. Applications in this report show how these models can be used to quantitatively assess the benefits that are expected from maintaining a component, the effects of different maintenance efficiencies, the merits of different maintenance policies, and the interaction of surveillance test intervals with maintenance practices

    1989-01-01

    The way an asteroid or other atmosphereless solar system body varies in brightness in response to changing illumination and viewing geometry depends in a very complicated way on the physical and optical properties of its surface and on its overall shape. The authors summarize the formulation and application of recent photometric models by Hapke and by Lumme and Bowell. In both models, the brightness of a rough and porous surface is parametrized in terms of the optical properties of individual particles, by shadowing between particles, and by the way in which light scattered among collections of particles. Both models succeed in their goal of fitting the observed photometric behavior of a wide variety of bodies, but neither has led to a very complete understanding of the properties of asteroid regoliths, primarily because in most cases the parameters in the present models cannot be adequately constrained by observations of integral brightness alone over a restricted range of phase angles

    A model, in computer aided engineering applications, may be created by either using a two- dimensional or a three-dimensional design depending on the purpose of design. What matters most in this regard is the selection of a right method to meet system solution requirements in the most economical way. Manufacturability of a design that is developed by utilising computer aided engineering is important, but usability of the data obtained in the course of design works in the production is also equally important. In the applications consisting of such production operations as CNC or plasma cutting, two-dimensional designs can be directly used in production. These machines are equipped with interfaces which converts two-dimensional drawings into codes. In this way, a design can be directly transferred to production, and any arrangements during production process can be synchronously evaluated. As a result of this, investment expenses will be lowered, and thus the costs can be reduced to some extent. In the presented study, we have studied two-dimensional design applications and requirements. We created a two-dimensional design for a part for which a three-dimensional model have previously been generated, and then, we transferred this design to plasma cutting machine, and thus, the operation has been realized experimentally. Key words: Plasma Cutting, 2D modelling, flexibility

  12. Models for dryout in debris beds. Review and application to the analysis of PAHR

    2000-03-01

    There are many models for dryout in debiris beds and various conditions under which these models are applicable. For a reliable analysis of post-accident heat removal (PAHR), it is important that characteristics and applicability of each model should be made clear. In this report, formulation of the models for dryout and applicability of them are studied through comparing with experimental data. A new model for dryout prediction is also discussed here. It is difficult to predict the dryout power especially for a relatively shallow bed using a conventional model for channeled beds. The new model, which is based on the one-dimensional model derived by Lipinski, has permeability of channels in the governing equation, and enables us to predict the dryout power for relatively shallow beds. The following conclusions are derived from comparing the predicted dryout power with experimental data. The model for series heat removal is applicable to a packed bed while the DEBRIS-MD underestimates the dryout power for it. Either the original model assuming channel formation on the top of the bed or the modified model is applicable to a relatively deep bed with channels. For a relatively shallow bed with channels, the dryout power predicted by the modified model agrees with the experimental data in comparison with other models. (author)

    Recent improvement in the quality of genetic data obtained from extinct human populations and their ancestors encourages searching for answers to basic questions regarding human population history. The most common and successful are model-based approaches, in which genetic data are compared to the data obtained from the assumed demography model. Using such approach, it is possible to either validate or adjust assumed demography. Model fit to data can be obtained based on reverse-time coalescent simulations or forward-time simulations. In this paper we introduce a computational method based on mathematical equation that allows obtaining joint distributions of pairs of individuals under a specified demography model, each of them characterized by a genetic variant at a chosen locus. The two individuals are randomly sampled from either the same or two different populations. The model assumes three types of demographic events (split, merge and migration). Populations evolve according to the time-continuous Moran model with drift and Markov-process mutation. This latter process is described by the Lyapunov-type equation introduced by O'Brien and generalized in our previous works. Application of this equation constitutes an original contribution. In the result section of the paper we present sample applications of our model to both simulated and literature-based demographies. Among other we include a study of the Slavs-Balts-Finns genetic relationship, in which we model split and migrations between the Balts and Slavs. We also include another example that involves the migration rates between farmers and hunters-gatherers, based on modern and ancient DNA samples. This latter process was previously studied using coalescent simulations. Our results are in general agreement with the previous method, which provides validation of our approach. Although our model is not an alternative to simulation methods in the practical sense, it provides an algorithm to compute pairwise

    Different models have been used in the literature for the simulation of surface contact in biomechanical knee models. However, there is a lack of systematic comparisons of these models applied to the simulation of a common case, which will provide relevant information about their accuracy and suitability for application in models of the implanted knee. In this work a comparison of the Hertz model (HM), the elastic foundation model (EFM) and the finite element model (FEM) for the simulation of the elastic contact in a 3D model of the prosthetic knee is presented. From the results of this comparison it is found that although the nature of the EFM offers advantages when compared with that of the HM for its application to realistic prosthetic surfaces, and when compared with the FEM in CPU time, its predictions can differ from FEM in some circumstances. These differences are considerable if the comparison is performed for prescribed displacements, although they are less important for prescribed loads. To solve these problems a new modified elastic foundation model (mEFM) is proposed that maintains basically the simplicity of the original model while producing much more accurate results. In this paper it is shown that this new mEFM calculates pressure distribution and contact area with accuracy and short computation times for toroidal contacting surfaces. Although further work is needed to confirm its validity for more complex geometries the mEFM is envisaged as a good option for application in 3D knee models to predict prosthetic knee performance.

    Full Text Available Internet television (IPTV is rapidly gaining popularity and is being widely deployed in content delivery networks on the Internet. In order to proactively deliver optimum user quality of experience (QoE for IPTV, service providers need to identify network bottlenecks in real time. In this paper, we develop psycho-acoustic-visual models that can predict user QoE of multimedia applications in real time based on online network status measurements. Our models are neural network based and cater to multi-resolution IPTV applications that include QCIF, QVGA, SD, and HD resolutions encoded using popular audio and video codec combinations. On the network side, our models account for jitter and loss levels, as well as router queuing disciplines: packet-ordered and time-ordered FIFO. We evaluate the performance of our multi-resolution multimedia QoE models in terms of prediction characteristics, accuracy, speed, and consistency. Our evaluation results demonstrate that the models are pertinent for real-time QoE monitoring and resource adaptation in IPTV content delivery networks.

    2018-07-01

    In the context of climate warming, the varying soil moisture caused by precipitation pattern change will affect the applicability of stomatal conductance models, thereby affecting the simulation accuracy of carbon-nitrogen-water cycles in ecosystems. We studied the applicability of four common stomatal conductance models including Jarvis, Ball-Woodrow-Berry (BWB), Ball-Berry-Leuning (BBL) and unified stomatal optimization (USO) models based on summer maize leaf gas exchange data from a soil moisture consecutive decrease manipulation experiment. The results showed that the USO model performed best, followed by the BBL model, BWB model, and the Jarvis model performed worst under varying soil moisture conditions. The effects of soil moisture made a difference in the relative performance among the models. By introducing a water response function, the performance of the Jarvis, BWB, and USO models improved, which decreased the normalized root mean square error (NRMSE) by 15.7%, 16.6% and 3.9%, respectively; however, the performance of the BBL model was negative, which increased the NRMSE by 5.3%. It was observed that the models of Jarvis, BWB, BBL and USO were applicable within different ranges of soil relative water content (i.e., 55%-65%, 56%-67%, 37%-79% and 37%-95%, respectively) based on the 95% confidence limits. Moreover, introducing a water response function, the applicability of the Jarvis and BWB models improved. The USO model performed best with or without introducing the water response function and was applicable under varying soil moisture conditions. Our results provide a basis for selecting appropriate stomatal conductance models under drought conditions. Copyright © 2018 Elsevier B.V. All rights reserved.

    This paper describes a modeling approach to analyze component degradation and failure data to understand the aging process of components. As used here, degradation modeling is the analysis of information on component degradation in order to develop models of the process and its implications. This particular modeling focuses on the analysis of the times of component degradations, to model how the rate of degradation changes with the age of the component. The methodology presented also discusses the effectiveness of maintenance as applicable to aging evaluations. The specific applications which are performed show quantitative models of component degradation rates and component failure rates from plant-specific data. The statistical techniques which are developed and applied allow aging trends to be effectively identified in the degradation data, and in the failure data. Initial estimates of the effectiveness of maintenance in limiting degradations from becoming failures also are developed. These results are important first steps in degradation modeling, and show that degradation can be modeled to identify aging trends. 2 refs., 8 figs

    Full Text Available This article presents an efficient method to capture abstract performance model of streaming data real-time embedded systems (RTESs. Unified Modeling Language version 2 (UML2 is used for the performance modeling and as a front-end for a tool framework that enables simulation-based performance evaluation and design-space exploration. The adopted application meta-model in UML resembles the Kahn Process Network (KPN model and it is targeted at simulation-based performance evaluation. The application workload modeling is done using UML2 activity diagrams, and platform is described with structural UML2 diagrams and model elements. These concepts are defined using a subset of the profile for Modeling and Analysis of Realtime and Embedded (MARTE systems from OMG and custom stereotype extensions. The goal of the performance modeling and simulation is to achieve early estimates on task response times, processing element, memory, and on-chip network utilizations, among other information that is used for design-space exploration. As a case study, a video codec application on multiple processors is modeled, evaluated, and explored. In comparison to related work, this is the first proposal that defines transformation between UML activity diagrams and streaming data application workload meta models and successfully adopts it for RTES performance evaluation.

  7. Application of a novel cellular automaton porosity prediction model to aluminium castings

    International Nuclear Information System (INIS)

    Atwood, R.C.; Chirazi, A.; Lee, P.D.

    2002-01-01

    A multiscale model was developed to predict the formation of porosity within a solidifying aluminium-silicon alloy. The diffusion of silicon and dissolved gas was simulated on a microscopic scale combined with cellular automaton models of gas porosity formation within the growing three-dimensional solidification microstructure. However, due to high computational cost, the modelled volume is limited to the millimetre range. This renders the application of direct modelling of complex shape castings unfeasible. Combining the microstructural modelling with a statistical response-surface prediction method allows application of the microstructural model results to industrial scale casts by incorporating them in commercial solidification software.

  8. Multivariate Birnbaum-Saunders Distributions: Modelling and Applications

    Directory of Open Access Journals (Sweden)

    Robert G. Aykroyd

    2018-03-01

    Full Text Available Since its origins and numerous applications in material science, the Birnbaum–Saunders family of distributions has now found widespread uses in some areas of the applied sciences such as agriculture, environment and medicine, as well as in quality control, among others. It is able to model varied data behaviour and hence provides a flexible alternative to the most usual distributions. The family includes Birnbaum–Saunders and log-Birnbaum–Saunders distributions in univariate and multivariate versions. There are now well-developed methods for estimation and diagnostics that allow in-depth analyses. This paper gives a detailed review of existing methods and of relevant literature, introducing properties and theoretical results in a systematic way. To emphasise the range of suitable applications, full analyses are included of examples based on regression and diagnostics in material science, spatial data modelling in agricultural engineering and control charts for environmental monitoring. However, potential future uses in new areas such as business, economics, finance and insurance are also discussed. This work is presented to provide a full tool-kit of novel statistical models and methods to encourage other researchers to implement them in these new areas. It is expected that the methods will have the same positive impact in the new areas as they have had elsewhere.

    Animal health is of societal importance as it affects human welfare, and anthropogenic interests shape decision making to assure animal health. Scientific advice to support decision making is manifold. Modelling, as one piece of the scientific toolbox, is appreciated for its ability to describe and structure data, to give insight in complex processes and to predict future outcome. In this paper we study the application of scientific modelling to support practical animal health decisions. We reviewed the 35 animal health related scientific opinions adopted by the Animal Health and Animal Welfare Panel of the European Food Safety Authority (EFSA). Thirteen of these documents were based on the application of models. The review took two viewpoints, the decision maker's need and the modeller's approach. In the reviewed material three types of modelling questions were addressed by four specific model types. The correspondence between tasks and models underpinned the importance of the modelling question in triggering the modelling approach. End point quantifications were the dominating request from decision makers, implying that prediction of risk is a major need. However, due to knowledge gaps corresponding modelling studies often shed away from providing exact numbers. Instead, comparative scenario analyses were performed, furthering the understanding of the decision problem and effects of alternative management options. In conclusion, the most adequate scientific support for decision making - including available modelling capacity - might be expected if the required advice is clearly stated.

    Detailed knowledge of near-shore topography and bathymetry is required for many geospatial data applications in the coastal environment. New data sources and processing methods are facilitating development of seamless, regional-scale topobathymetric digital elevation models. These elevation models integrate disparate multi-sensor, multi-temporal topographic and bathymetric datasets to provide a coherent base layer for coastal science applications such as wetlands mapping and monitoring, sea-level rise assessment, benthic habitat mapping, erosion monitoring, and storm impact assessment. The focus of this special issue is on recent advances in the source data, data processing and integration methods, and applications of topobathymetric datasets.

    2013-12-01

    The Five-Factor Model (FFM) has become the predominant dimensional model of general personality structure. The purpose of this paper is to suggest a clinical application. A substantial body of research indicates that the personality disorders included within the American Psychiatric Association's (APA) Diagnostic and Statistical Manual of Mental Disorders (DSM) can be understood as extreme and/or maladaptive variants of the FFM (the acronym "DSM" refers to any particular edition of the APA DSM). In addition, the current proposal for the forthcoming fifth edition of the DSM (i.e., DSM-5) is shifting closely toward an FFM dimensional trait model of personality disorder. Advantages of this shifting conceptualization are discussed, including treatment planning. © 2012 Wiley Periodicals, Inc.

  18. The sound of friction: Real-time models, playability and musical applications

    Science.gov (United States)

    Serafin, Stefania

    Friction, the tangential force between objects in contact, in most engineering applications needs to be removed as a source of noise and instabilities. In musical applications, friction is a desirable component, being the sound production mechanism of different musical instruments such as bowed strings, musical saws, rubbed bowls and any other sonority produced by interactions between rubbed dry surfaces. The goal of the dissertation is to simulate different instrument whose main excitation mechanism is friction. An efficient yet accurate model of a bowed string instrument, which combines the latest results in violin acoustics with the efficient digital waveguide approach, is provided. In particular, the bowed string physical model proposed uses a thermodynamic friction model in which the finite width of the bow is taken into account; this solution is compared to the recently developed elasto-plastic friction models used in haptics and robotics. Different solutions are also proposed to model the body of the instrument. Other less common instruments driven by friction are also proposed, and the elasto-plastic model is used to provide audio-visual simulations of everyday friction sounds such as squeaking doors and rubbed wine glasses. Finally, playability evaluations and musical applications in which the models have been used are discussed.

    Investigations of recent physics processes and real applications of models require the new more and more improved models which should involved new properties. One of such properties is anticipation (that is taking into accounting some advanced effects).It is considered the special kind of advanced systems – namely a strong anticipatory systems introduced by D. Dubois. Some definitions, examples and peculiarities of solutions are described. The main feature is presumable multivaluedness of the solutions. Presumable physical examples of such systems are proposed: self-organization problems; dynamical chaos; synchronization; advanced potentials; structures in micro-, meso- and macro- levels; cellular automata; computing; neural network theory. Also some applications for modeling social, economical, technical and natural systems are described.

  20. Animal models of enterovirus 71 infection: applications and limitations

    Science.gov (United States)

    2014-01-01

    Human enterovirus 71 (EV71) has emerged as a neuroinvasive virus that is responsible for several outbreaks in the Asia-Pacific region over the past 15 years. Appropriate animal models are needed to understand EV71 neuropathogenesis better and to facilitate the development of effective vaccines and drugs. Non-human primate models have been used to characterize and evaluate the neurovirulence of EV71 after the early outbreaks in late 1990s. However, these models were not suitable for assessing the neurovirulence level of the virus and were associated with ethical and economic difficulties in terms of broad application. Several strategies have been applied to develop mouse models of EV71 infection, including strategies that employ virus adaption and immunodeficient hosts. Although these mouse models do not closely mimic human disease, they have been applied to determine the pathogenesis of and treatment and prevention of the disease. EV71 receptor-transgenic mouse models have recently been developed and have significantly advanced our understanding of the biological features of the virus and the host-parasite interactions. Overall, each of these models has advantages and disadvantages, and these models are differentially suited for studies of EV71 pathogenesis and/or the pre-clinical testing of antiviral drugs and vaccines. In this paper, we review the characteristics, applications and limitation of these EV71 animal models, including non-human primate and mouse models. PMID:24742252

  1. Calibration Modeling Methodology to Optimize Performance for Low Range Applications

    Science.gov (United States)

    McCollum, Raymond A.; Commo, Sean A.; Parker, Peter A.

    2010-01-01

    Calibration is a vital process in characterizing the performance of an instrument in an application environment and seeks to obtain acceptable accuracy over the entire design range. Often, project requirements specify a maximum total measurement uncertainty, expressed as a percent of full-scale. However in some applications, we seek to obtain enhanced performance at the low range, therefore expressing the accuracy as a percent of reading should be considered as a modeling strategy. For example, it is common to desire to use a force balance in multiple facilities or regimes, often well below its designed full-scale capacity. This paper presents a general statistical methodology for optimizing calibration mathematical models based on a percent of reading accuracy requirement, which has broad application in all types of transducer applications where low range performance is required. A case study illustrates the proposed methodology for the Mars Entry Atmospheric Data System that employs seven strain-gage based pressure transducers mounted on the heatshield of the Mars Science Laboratory mission.

    2018-03-01

    Process-based numerical models are increasingly used to study the evolution of marine and terrestrial depositional environments. Whilst a detailed description of small-scale processes provides an accurate representation of reality, application on geological timescales is restrained by the associated increase in computational time. In order to reduce the computational time, a number of acceleration methods are combined and evaluated for a schematic supply-driven delta (static base level) and an accommodation-driven delta (variable base level). The performance of the combined acceleration methods is evaluated by comparing the morphological indicators such as distributary channel networking and delta volumes derived from the model predictions for various levels of acceleration. The results of the accelerated models are compared to the outcomes from a series of simulations to capture autogenic variability. Autogenic variability is quantified by re-running identical models on an initial bathymetry with 1 cm added noise. The overall results show that the variability of the accelerated models fall within the autogenic variability range, suggesting that the application of acceleration methods does not significantly affect the simulated delta evolution. The Time-scale compression method (the acceleration method introduced in this paper) results in an increased computational efficiency of 75% without adversely affecting the simulated delta evolution compared to a base case. The combination of the Time-scale compression method with the existing acceleration methods has the potential to extend the application range of process-based models towards geologic timescales.

    2014-03-01

    The paper focuses on the further development of the model of the electromechanical impedance (EMI) of the piezoceramics transducer (PZT) and its application for aircraft structural health monitoring (SHM). There was obtained an expression of the electromechanical impedance common to any dimension of models (1D, 2D, 3D), and directly independent from imposed constraints. Determination of the dynamic response of the system "host structure - PZT", which is crucial for the practical application supposes the use of modal analysis. This allows to get a general tool to determine EMI regardless of the specific features of a particular application. Earlier there was considered the technology of separate determination of the dynamic response for the PZT and the structural element". Here another version that involves the joint modal analysis of the entire system "host structure - PZT" is presented. As a result, the dynamic response is obtained in the form of modal decomposition of transducer mechanical strains. The use of models for the free and constrained transducer, analysis of the impact of the adhesive layer to the EMI is demonstrated. In all cases there was analyzed the influence of the dimension of the model (2D and 3D). The validity of the model is confirmed by experimental studies. Correlation between the fatigue crack length in a thin-walled Al plate and EMI of embedded PZT was simulated and compared with test result.

  15. Application of Chaos Theory to Psychological Models

    Science.gov (United States)

    Blackerby, Rae Fortunato

    This dissertation shows that an alternative theoretical approach from physics--chaos theory--offers a viable basis for improved understanding of human beings and their behavior. Chaos theory provides achievable frameworks for potential identification, assessment, and adjustment of human behavior patterns. Most current psychological models fail to address the metaphysical conditions inherent in the human system, thus bringing deep errors to psychological practice and empirical research. Freudian, Jungian and behavioristic perspectives are inadequate psychological models because they assume, either implicitly or explicitly, that the human psychological system is a closed, linear system. On the other hand, Adlerian models that require open systems are likely to be empirically tenable. Logically, models will hold only if the model's assumptions hold. The innovative application of chaotic dynamics to psychological behavior is a promising theoretical development because the application asserts that human systems are open, nonlinear and self-organizing. Chaotic dynamics use nonlinear mathematical relationships among factors that influence human systems. This dissertation explores these mathematical relationships in the context of a sample model of moral behavior using simulated data. Mathematical equations with nonlinear feedback loops describe chaotic systems. Feedback loops govern the equations' value in subsequent calculation iterations. For example, changes in moral behavior are affected by an individual's own self-centeredness, family and community influences, and previous moral behavior choices that feed back to influence future choices. When applying these factors to the chaos equations, the model behaves like other chaotic systems. For example, changes in moral behavior fluctuate in regular patterns, as determined by the values of the individual, family and community factors. In some cases, these fluctuations converge to one value; in other cases, they diverge in

    2013-01-01

    Full Text Available The modeling of the heating, ventilation, and air conditioning (HVAC system is a prominent topic because of its relationship with energy savings and environmental, economical, and technological issues. The modeling of the HVAC system is concerned with the indoor thermal sensation, which is related to the modeling of building, air handling unit (AHU equipments, and indoor thermal processes. Until now, many HVAC system modeling approaches are made available, and the techniques have become quite mature. But there are some shortcomings in application and integration methods for the different types of the HVAC model. The application and integration processes will act to accumulate the defective characteristics for both AHU equipments and building models such as nonlinear, pure lag time, high thermal inertia, uncertain disturbance factors, large-scale systems, and constraints. This paper shows types of the HVAC model and the advantages and disadvantages for each application of them, and it finds out that the gray-box type is the best one to represent the indoor thermal comfort. But its application fails at the integration method where its response deviated to unreal behavior.

  17. Using the object modeling system for hydrological model development and application

    Directory of Open Access Journals (Sweden)

    2005-01-01

    Full Text Available State of the art challenges in sustainable management of water resources have created demand for integrated, flexible and easy to use hydrological models which are able to simulate the quantitative and qualitative aspects of the hydrological cycle with a sufficient degree of certainty. Existing models which have been de-veloped to fit these needs are often constrained to specific scales or purposes and thus can not be easily adapted to meet different challenges. As a solution for flexible and modularised model development and application, the Object Modeling System (OMS has been developed in a joint approach by the USDA-ARS, GPSRU (Fort Collins, CO, USA, USGS (Denver, CO, USA, and the FSU (Jena, Germany. The OMS provides a modern modelling framework which allows the implementation of single process components to be compiled and applied as custom tailored model assemblies. This paper describes basic principles of the OMS and its main components and explains in more detail how the problems during coupling of models or model components are solved inside the system. It highlights the integration of different spatial and temporal scales by their representation as spatial modelling entities embedded into time compound components. As an exam-ple the implementation of the hydrological model J2000 is discussed.

    Byrne, Barbara M

    2013-01-01

    Readers who want a less mathematical alternative to the EQS manual will find exactly what they're looking for in this practical text. Written specifically for those with little to no knowledge of structural equation modeling (SEM) or EQS, the author's goal is to provide a non-mathematical introduction to the basic concepts of SEM by applying these principles to EQS, Version 6.1. The book clearly demonstrates a wide variety of SEM/EQS applications that include confirmatory factor analytic and full latent variable models. Written in a "user-friendly" style, the author "walks" the reader through the varied steps involved in the process of testing SEM models: model specification and estimation, assessment of model fit, EQS output, and interpretation of findings. Each of the book's applications is accompanied by: a statement of the hypothesis being tested, a schematic representation of the model, explanations of the EQS input and output files, tips on how to use the pull-down menus, and the data file upon which ...

    2015-01-01

    The hydrodynamic parameters measured in an AUC experiment, s(20,w) and D(t)(20,w)(0), can be used to gain information on the solution structure of (bio)macromolecules and their assemblies. This entails comparing the measured parameters with those that can be computed from usually "dry" structures by "hydrodynamic modeling." In this chapter, we will first briefly put hydrodynamic modeling in perspective and present the basic physics behind it as implemented in the most commonly used methods. The important "hydration" issue is also touched upon, and the distinction between rigid bodies versus those for which flexibility must be considered in the modeling process is then made. The available hydrodynamic modeling/computation programs, HYDROPRO, BEST, SoMo, AtoB, and Zeno, the latter four all implemented within the US-SOMO suite, are described and their performance evaluated. Finally, some literature examples are presented to illustrate the potential applications of hydrodynamics in the expanding field of multiresolution modeling. © 2015 Elsevier Inc.

    2004-11-01

    Limited spectral response range of photocoltaic (PV) devices requires device performance be characterized with respect to widely varying terrestrial solar spectra. The FORTRAN code "Simple Model for Atmospheric Transmission of Sunshine" (SMARTS) was developed for various clear-sky solar renewable energy applications. The model is partly based on parameterizations of transmittance functions in the MODTRAN/LOWTRAN band model family of radiative transfer codes. SMARTS computes spectra with a resolution of 0.5 nanometers (nm) below 400 nm, 1.0 nm from 400 nm to 1700 nm, and 5 nm from 1700 nm to 4000 nm. Fewer than 20 input parameters are required to compute spectral irradiance distributions including spectral direct beam, total, and diffuse hemispherical radiation, and up to 30 other spectral parameters. A spreadsheet-based graphical user interface can be used to simplify the construction of input files for the model. The model is the basis for new terrestrial reference spectra developed by the American Society for Testing and Materials (ASTM) for photovoltaic and materials degradation applications. We describe the model accuracy, functionality, and the availability of source and executable code. Applications to PV rating and efficiency and the combined effects of spectral selectivity and varying atmospheric conditions are briefly discussed.

  5. A comprehensive model for piezoceramic actuators: modelling, validation and application

    Quant, Mario; Elizalde, Hugo; Flores, Abiud; Ramírez, Ricardo; Orta, Pedro; Song, Gangbing

    2009-01-01

    This paper presents a comprehensive model for piezoceramic actuators (PAs), which accounts for hysteresis, non-linear electric field and dynamic effects. The hysteresis model is based on the widely used general Maxwell slip model, while an enhanced electro-mechanical non-linear model replaces the linear constitutive equations commonly used. Further on, a linear second order model compensates the frequency response of the actuator. Each individual model is fully characterized from experimental data yielded by a specific PA, then incorporated into a comprehensive 'direct' model able to determine the output strain based on the applied input voltage, fully compensating the aforementioned effects, where the term 'direct' represents an electrical-to-mechanical operating path. The 'direct' model was implemented in a Matlab/Simulink environment and successfully validated via experimental results, exhibiting higher accuracy and simplicity than many published models. This simplicity would allow a straightforward inclusion of other behaviour such as creep, ageing, material non-linearity, etc, if such parameters are important for a particular application. Based on the same formulation, two other models are also presented: the first is an 'alternate' model intended to operate within a force-controlled scheme (instead of a displacement/position control), thus able to capture the complex mechanical interactions occurring between a PA and its host structure. The second development is an 'inverse' model, able to operate within an open-loop control scheme, that is, yielding a 'linearized' PA behaviour. The performance of the developed models is demonstrated via a numerical sample case simulated in Matlab/Simulink, consisting of a PA coupled to a simple mechanical system, aimed at shifting the natural frequency of the latter

  6. Agent Based Modeling Applications for Geosciences

    Stein, J. S.

    2004-12-01

    Agent-based modeling techniques have successfully been applied to systems in which complex behaviors or outcomes arise from varied interactions between individuals in the system. Each individual interacts with its environment, as well as with other individuals, by following a set of relatively simple rules. Traditionally this "bottom-up" modeling approach has been applied to problems in the fields of economics and sociology, but more recently has been introduced to various disciplines in the geosciences. This technique can help explain the origin of complex processes from a relatively simple set of rules, incorporate large and detailed datasets when they exist, and simulate the effects of extreme events on system-wide behavior. Some of the challenges associated with this modeling method include: significant computational requirements in order to keep track of thousands to millions of agents, methods and strategies of model validation are lacking, as is a formal methodology for evaluating model uncertainty. Challenges specific to the geosciences, include how to define agents that control water, contaminant fluxes, climate forcing and other physical processes and how to link these "geo-agents" into larger agent-based simulations that include social systems such as demographics economics and regulations. Effective management of limited natural resources (such as water, hydrocarbons, or land) requires an understanding of what factors influence the demand for these resources on a regional and temporal scale. Agent-based models can be used to simulate this demand across a variety of sectors under a range of conditions and determine effective and robust management policies and monitoring strategies. The recent focus on the role of biological processes in the geosciences is another example of an area that could benefit from agent-based applications. A typical approach to modeling the effect of biological processes in geologic media has been to represent these processes in

    Performance modeling of extreme-scale applications on accurate representations of potential architectures is critical for designing next generation supercomputing systems because it is impractical to construct prototype systems at scale with new network hardware in order to explore designs and policies. However, these simulations often rely on static application traces that can be difficult to work with because of their size and lack of flexibility to extend or scale up without rerunning the original application. To address this problem, we have created a new technique for generating scalable, flexible workloads from real applications, we have implemented a prototype, called Durango, that combines a proven analytical performance modeling language, Aspen, with the massively parallel HPC network modeling capabilities of the CODES framework.Our models are compact, parameterized and representative of real applications with computation events. They are not resource intensive to create and are portable across simulator environments. We demonstrate the utility of Durango by simulating the LULESH application in the CODES simulation environment on several topologies and show that Durango is practical to use for simulation without loss of fidelity, as quantified by simulation metrics. During our validation of Durango's generated communication model of LULESH, we found that the original LULESH miniapp code had a latent bug where the MPI_Waitall operation was used incorrectly. This finding underscores the potential need for a tool such as Durango, beyond its benefits for flexible workload generation and modeling.Additionally, we demonstrate the efficacy of Durango's direct integration approach, which links Aspen into CODES as part of the running network simulation model. Here, Aspen generates the application-level computation timing events, which in turn drive the start of a network communication phase. Results show that Durango's performance scales well when

    2014-01-01

    Advances in mathematical model applications toward the understanding of the complex flow, characterization, and water-supply management issues for karst aquifers have occurred in recent years. Different types of mathematical models can be applied successfully if appropriate information is available and the problems are adequately identified. The mathematical approaches discussed in this paper are divided into three major categories: 1) distributed parameter models, 2) lumped parameter models, and 3) fitting models. The modeling approaches are described conceptually with examples (but without equations) to help non-mathematicians understand the applications.

  9. Efficiency of coherent-state quantum cryptography in the presence of loss: Influence of realistic error correction

    2006-01-01

    We investigate the performance of a continuous-variable quantum key distribution scheme in a practical setting. More specifically, we take a nonideal error reconciliation procedure into account. The quantum channel connecting the two honest parties is assumed to be lossy but noiseless. Secret key rates are given for the case that the measurement outcomes are postselected or a reverse reconciliation scheme is applied. The reverse reconciliation scheme loses its initial advantage in the practical setting. If one combines postselection with reverse reconciliation, however, much of this advantage can be recovered

    Full Text Available Purpose: Purpose: This paper mainly focus on the application of adversarial risk analysis (ARA in pricing strategy with remanufacturing. We hope to obtain more realistic results than classical model. Moreover, we also wish that our research improve the development of ARA in pricing strategy of manufacturing or remanufacturing. Approach: In order to gain more actual research, combining adversarial risk analysis, we explore the pricing strategy with remanufacturing based on Stackelberg model. Especially, we build OEM’s 1-order ARA model and further study on manufacturers and remanufacturers’ pricing strategy. Findings: We find the OEM’s 1-order ARA model for the OEM’s product cost C. Besides, we get according manufacturers and remanufacturers’ pricing strategies. Besides, the pricing strategies based on 1-order ARA model have advantage over than the classical model regardless of OEMs and remanufacturers. Research implications: The research on application of ARA imply that we can get more actual results with this kind of modern risk analysis method and ARA can be extensively in pricing strategies of supply chain. Value: Our research improves the application of ARA in remanufacturing industry. Meanwhile, inspired by this analysis, we can also create different ARA models for different parameters. Furthermore, some results and analysis methods can be applied to other pricing strategies of supply chain.

    In this paper, we present a performance modeling framework based on memory bandwidth contention time and a parameterized communication model to predict the performance of OpenMP, MPI and hybrid applications with weak scaling on three large-scale multicore supercomputers: IBM POWER4, POWER5+ and BlueGene/P, and analyze the performance of these MPI, OpenMP and hybrid applications. We use STREAM memory benchmarks and Intel's MPI benchmarks to provide initial performance analysis and model validation of MPI and OpenMP applications on these multicore supercomputers because the measured sustained memory bandwidth can provide insight into the memory bandwidth that a system should sustain on scientific applications with the same amount of workload per core. In addition to using these benchmarks, we also use a weak-scaling hybrid MPI/OpenMP large-scale scientific application: Gyrokinetic Toroidal Code (GTC) in magnetic fusion to validate our performance model of the hybrid application on these multicore supercomputers. The validation results for our performance modeling method show less than 7.77% error rate in predicting the performance of hybrid MPI/OpenMP GTC on up to 512 cores on these multicore supercomputers. © 2013 Elsevier Inc.

  19. Modelling a New Product Model on the Basis of an Existing STEP Application Protocol

    Directory of Open Access Journals (Sweden)

    B.-R. Hoehn

    2005-01-01

    Full Text Available During the last years a great range of computer aided tools has been generated to support the development process of various products. The goal of a continuous data flow, needed for high efficiency, requires powerful standards for the data exchange. At the FZG (Gear Research Centre of the Technical University of Munich there was a need for a common gear data format for data exchange between gear calculation programs. The STEP standard ISO 10303 was developed for this type of purpose, but a suitable definition of gear data was still missing, even in the Application Protocol AP 214, developed for the design process in the automotive industry. The creation of a new STEP Application Protocol or the extension of existing protocol would be a very time consumpting normative process. So a new method was introduced by FZG. Some very general definitions of an Application Protocol (here AP 214 were used to determine rules for an exact specification of the required kind of data. In this case a product model for gear units was defined based on elements of the AP 214. Therefore no change of the Application Protocol is necessary. Meanwhile the product model for gear units has been published as a VDMA paper and successfully introduced for data exchange within the German gear industry associated with FVA (German Research Organisation for Gears and Transmissions. This method can also be adopted for other applications not yet sufficiently defined by STEP. 

  20. Methodology and application of combined watershed and ground-water models in Kansas

    Science.gov (United States)

    Sophocleous, M.; Perkins, S.P.

    2000-01-01

    Increased irrigation in Kansas and other regions during the last several decades has caused serious water depletion, making the development of comprehensive strategies and tools to resolve such problems increasingly important. This paper makes the case for an intermediate complexity, quasi-distributed, comprehensive, large-watershed model, which falls between the fully distributed, physically based hydrological modeling system of the type of the SHE model and the lumped, conceptual rainfall-runoff modeling system of the type of the Stanford watershed model. This is achieved by integrating the quasi-distributed watershed model SWAT with the fully-distributed ground-water model MODFLOW. The advantage of this approach is the appreciably smaller input data requirements and the use of readily available data (compared to the fully distributed, physically based models), the statistical handling of watershed heterogeneities by employing the hydrologic-response-unit concept, and the significantly increased flexibility in handling stream-aquifer interactions, distributed well withdrawals, and multiple land uses. The mechanics of integrating the component watershed and ground-water models are outlined, and three real-world management applications of the integrated model from Kansas are briefly presented. Three different aspects of the integrated model are emphasized: (1) management applications of a Decision Support System for the integrated model (Rattlesnake Creek subbasin); (2) alternative conceptual models of spatial heterogeneity related to the presence or absence of an underlying aquifer with shallow or deep water table (Lower Republican River basin); and (3) the general nature of the integrated model linkage by employing a watershed simulator other than SWAT (Wet Walnut Creek basin). These applications demonstrate the practicality and versatility of this relatively simple and conceptually clear approach, making public acceptance of the integrated watershed modeling

    In this study, the concept of social capital is applied to an exploration of Guanxi (social networking to create good relationships) among working lone mothers of adults with intellectual disabilities (ID) in Taiwan. Using in-depth interviews, this study explores the role of social capital, here referred to as 'care capital', in making it possible for working lone mothers to combine their roles as family carers and workers. Eleven divorced or widowed mothers combining their paid work with long-term care responsibilities were recruited from a survey or through NGOs and were interviewed at their home between October 2008 and July 2010. An interpretative phenomenological approach was adopted for data analysis. The findings revealed that the mothers' care capital was extremely limited and was lost, gained and lost again during their life-cycles of long-term care-giving. Guanxi, especially in relation to their employers, proved to be the sole source of care capital for these mothers, making reconciliation between work and care responsibilities possible. In the absence of formal or informal support, religion and the mother-child relationship seemed also to become a kind of care capital for these lone mothers, helping them to get by with their life-long care responsibilities. For formal social and healthcare services, not just in Taiwan but in every country, it is important to develop support for lone mothers of adults with ID who have long-term care responsibilities and low levels of care capital and thus face care poverty. © 2014 John Wiley & Sons Ltd.

    2017-12-01

      Introduction: As part of the Truth and Reconciliation Commission of Canada’s (TRC Final Report on the history and legacy of residential schools in Canada, ninety-four (94 Calls to Action were identified. Of those, seven are health-specific. The objective of this research paper is to determine how Canadian health library websites are responding to these calls to action.   Methods: The authors conducted an initial literature review to gain an understanding of the context of Indigenous health in Canada. A content analysis of Canadian health library websites was conducted to track mentions of the TRC and their responses to the need for Indigenous-focused resources.   Results: The results of content analysis indicated few online responses to the TRC’s Calls to Action from Canadian health libraries. Only thirty-three per cent of Canadian health libraries had content that was Indigenous-focused, and only about fifteen per cent of health libraries had visible content related to the TRC’s Calls to Action. Academic and consumer health libraries were more likely to have both TRC- and Indigenous-focused content.   Discussion: Nuances related to the research question resulted in some challenges to research design. For example, website content analysis is an imperfect indicator of real-world action. Limitations in research design notwithstanding, visibility is an important part of conveying commitment to the TRC, and the information available indicates the Canadian medical community is not living up to that commitment.   Conclusion: Canadian health libraries need to do more to show a visible commitment to the TRC’s Calls to Action.

  3. A review of model applications for structured soils: b) Pesticide transport.

    Science.gov (United States)

    2009-02-16

    The past decade has seen considerable progress in the development of models simulating pesticide transport in structured soils subject to preferential flow (PF). Most PF pesticide transport models are based on the two-region concept and usually assume one (vertical) dimensional flow and transport. Stochastic parameter sets are sometimes used to account for the effects of spatial variability at the field scale. In the past decade, PF pesticide models were also coupled with Geographical Information Systems (GIS) and groundwater flow models for application at the catchment and larger regional scales. A review of PF pesticide model applications reveals that the principal difficulty of their application is still the appropriate parameterization of PF and pesticide processes. Experimental solution strategies involve improving measurement techniques and experimental designs. Model strategies aim at enhancing process descriptions, studying parameter sensitivity, uncertainty, inverse parameter identification, model calibration, and effects of spatial variability, as well as generating model emulators and databases. Model comparison studies demonstrated that, after calibration, PF pesticide models clearly outperform chromatographic models for structured soils. Considering nonlinear and kinetic sorption reactions further enhanced the pesticide transport description. However, inverse techniques combined with typically available experimental data are often limited in their ability to simultaneously identify parameters for describing PF, sorption, degradation and other processes. On the other hand, the predictive capacity of uncalibrated PF pesticide models currently allows at best an approximate (order-of-magnitude) estimation of concentrations. Moreover, models should target the entire soil-plant-atmosphere system, including often neglected above-ground processes such as pesticide volatilization, interception, sorption to plant residues, root uptake, and losses by runoff.

    Medical travel has expanded rapidly in recent years, resulting in new markets and increased access to medical care.

    Medical travel has expanded rapidly in recent years, resulting in new markets and increased access to medical care. Whereas several studies investigated the motives of individuals seeking healthcare abroad, the conventional analytical approach is limited by substantial caveats. Classical techniques as found in the literature cannot provide sufficient insight due to the nested nature of data generated. The application of adequate analytical techniques, specifically multilevel modeling, is scarce to non-existent in the context of medical travel. This study introduces the guidelines for application of multilevel techniques in public health research by presenting an application of multilevel modeling in analyzing the decision-making patterns of potential medical travelers. Benefits and potential limitations are discussed.

    2013-01-01

    A flexible, cell-level, and lattice-based technique, the cellular Potts model accurately describes the phenomenological mechanisms involved in many biological processes. Cellular Potts Models: Multiscale Extensions and Biological Applications gives an interdisciplinary, accessible treatment of these models, from the original methodologies to the latest developments. The book first explains the biophysical bases, main merits, and limitations of the cellular Potts model. It then proposes several innovative extensions, focusing on ways to integrate and interface the basic cellular Potts model at the mesoscopic scale with approaches that accurately model microscopic dynamics. These extensions are designed to create a nested and hybrid environment, where the evolution of a biological system is realistically driven by the constant interplay and flux of information between the different levels of description. Through several biological examples, the authors demonstrate a qualitative and quantitative agreement with t...

  13. Application of model based control to robotic manipulators

    A robot that can duplicate humam motion capabilities in such activities as balancing, reaching, lifting, and moving has been built and tested. These capabilities are achieved through the use of real time Model-Based Control (MBC) techniques which have recently been demonstrated. MBC accounts for all manipulator inertial forces and provides stable manipulator motion control even at high speeds. To effectively demonstrate the unique capabilities of MBC, an experimental robotic manipulator was constructed, which stands upright, balancing on a two wheel base. The mathematical modeling of dynamics inherent in MBC permit the control system to perform functions that are impossible with conventional non-model based methods. These capabilities include: (1) Stable control at all speeds of operation; (2) Operations requiring dynamic stability such as balancing; (3) Detection and monitoring of applied forces without the use of load sensors; (4) Manipulator safing via detection of abnormal loads. The full potential of MBC has yet to be realized. The experiments performed for this research are only an indication of the potential applications. MBC has no inherent stability limitations and its range of applicability is limited only by the attainable sampling rate, modeling accuracy, and sensor resolution. Manipulators could be designed to operate at the highest speed mechanically attainable without being limited by control inadequacies. Manipulators capable of operating many times faster than current machines would certainly increase productivity for many tasks.

  16. Probing Mantle Heterogeneity Across Spatial Scales

    Inferences of mantle heterogeneity in terms of temperature, composition, grain size, melt and crystal structure may vary across local, regional and global scales. Probing these scale-dependent effects require quantitative comparisons and reconciliation of tomographic models that vary in their regional scope, parameterization, regularization and observational constraints. While a range of techniques like radial correlation functions and spherical harmonic analyses have revealed global features like the dominance of long-wavelength variations in mantle heterogeneity, they have limited applicability for specific regions of interest like subduction zones and continental cratons. Moreover, issues like discrepant 1-D reference Earth models and related baseline corrections have impeded the reconciliation of heterogeneity between various regional and global models. We implement a new wavelet-based approach that allows for structure to be filtered simultaneously in both the spectral and spatial domain, allowing us to characterize heterogeneity on a range of scales and in different geographical regions. Our algorithm extends a recent method that expanded lateral variations into the wavelet domain constructed on a cubed sphere. The isolation of reference velocities in the wavelet scaling function facilitates comparisons between models constructed with arbitrary 1-D reference Earth models. The wavelet transformation allows us to quantify the scale-dependent consistency between tomographic models in a region of interest and investigate the fits to data afforded by heterogeneity at various dominant wavelengths. We find substantial and spatially varying differences in the spectrum of heterogeneity between two representative global Vp models constructed using different data and methodologies. Applying the orthonormality of the wavelet expansion, we isolate detailed variations in velocity from models and evaluate additional fits to data afforded by adding such complexities to long

    Full Text Available This article touched, in brief, the recent advances in dental materials and geometric modelling in dental applications. Most common categories of dental materials as metallic alloys, composites, ceramics and nanomaterials were briefly demonstrated. Nanotechnology improved the quality of dental biomaterials. This new technology improves many existing materials properties, also, to introduce new materials with superior properties that covered a wide range of applications in dentistry. Geometric modelling was discussed as a concept and examples within this article. The geometric modelling with engineering Computer-Aided-Design (CAD system(s is highly satisfactory for further analysis or Computer-Aided-Manufacturing (CAM processes. The geometric modelling extracted from Computed-Tomography (CT images (or its similar techniques for the sake of CAM also reached a sufficient level of accuracy, while, obtaining efficient solid modelling without huge efforts on body surfaces, faces, and gaps healing is still doubtable. This article is merely a compilation of knowledge learned from lectures, workshops, books, and journal articles, articles from the internet, dental forum, and scientific groups' discussions.
