    Evaluate three standard operational procedures (SOPs), regarding the application of the brainstem auditory evoked potential (BAEP) test, implemented by the Audiology Department of the Center for Studies in Occupational Health and Human Ecology (CESTEH) through the application of a questionnaire and to verify whether the SOPs are effective and assess the necessity for improvement. The study was conducted in three phases: in the first phase, eight speech-language pathologists and seven physicians, with no experience in BAEP, were instructed to read and perform each SOP, eventually all individuals evaluated the SOPs by responding to a questionnaire; in the second phase, the questionnaires were analyzed and the three SOP texts were reviewed; in the third phase, nine speech-language pathologists and six physicians, also with no experience in BAEP, read and re-evaluated the reviewed SOPs through a questionnaire. In the first phase, difficulties in understanding the texts were found, raising doubts about the procedures; however, every participant was able to perform the procedure as a whole. In the third phase, after the review, all individuals were able to perform the procedures appropriately and continuously without any doubts. The assessment of the SOPs by questionnaires showed the need for adaptation in the texts. After the texts were reviewed according to the suggestions of the health professionals, it was possible to observe that the SOPs assisted in the execution of the task, which was conducted without any difficulties or doubts, being regarded effective and ensuring quality to the service offered.

    The purpose of the present study is to see whether we follow global guidelines for operative procedures and diagnoses for impacted and retained teeth, and to compare these results with older results in Croatia. Operative protocols from Department of Oral Surgery, School of Dental Medicine, Zagreb in the period from 1997 till 1999 were used in the present study. 4756 patients were operated (total of 4857 diagnosis were set). Of all diagnoses, 24.89% (N=1209) belongs to dens impactus, 5.13% (N=249) to dens semiimpactus, 6.05% (N=294) to dens retentus and 0.64% (N=31) to dentitio difficilis. These four diagnoses make 36.71% of all 4857 set diagnoses. Most commonly impacted teeth are: 8- (38.64%), -8 (35.88%), 8+ (10.9%) and +8 (9.29%). Most commonly retained teeth are: 3+ (19.1%) and +3 (18.8%), while in the remaining two diagnoses -8 and 8- are most commonly diagnosed and operated teeth. Impacted teeth are in 97.90% of the cases operated by alveolotomy procedure. With semiimpacted teeth alveolotomy was conducted in 94.12% cases, and 5.10% of such teeth were extracted. With retained teeth alveolotomy was conducted in 65.21%, corticotomy in 23.01% and extraction in 8.77% of the cases. With dentitio difficilis alveolotomy was applied in 46.88%, extraction in 37.50%, circumcision in 9.38% and corticotomy in 6.25% of the cases. Intra muscular corticosteroids (Dexamethason) were used in 2.80% of the cases, most commonly with dens impactus and dens retentus diagnosis. PHD was done in 4.21% cases. Although its use is on the increase, Dexamethason is still rarely used in everyday practice, despite global guidelines for the postoperative use of corticosteroids. PHD analysis is used most commonly with retained teeth since they usually come with follicular cysts. Anesthesia without epinephrine was used in only 1.80% of the operating procedures, because the epinephrine solution used at Oral Surgery Department is 1:160000.

    Quantitative hazard assessments (QHAs) are being used to support the US Department of Energy (DOE) Integrated Safety Process (SS-21), Nuclear Explosive Safety Studies (NESS), and Environmental Safety and Health (ES&H) initiatives. The QHAs are used to identify hazards associated with DOE nuclear explosive operations. In 1994, Los Alamos National Laboratory, Sandia National Laboratory, and the Pantex Plant participated in a joint effort to demonstrate the utility of performing hazard assessments (HAs) concurrently with process design and development efforts. Early identification of high risk operations allow for process modifications before final process design is completed. This demonstration effort, which used an integrated design process (SS-21), resulted in the redesign of the dismantlement process for the B61 center case. The SS-21 program integrates environment, safety, and health (ES&H) and nuclear explosive safety requirements. QHAs are used to identify accidents that have the potential for worker injury or public health or environmental impact. The HA is to evaluate the likelihood of accident sequences that have the potential for worker or public injury or environmental damage; identify safety critical tooling and procedural steps; identify operational safety controls; identify safety-class/significant systems, structures and components; identify dominant accident sequences; demonstrate that the facility Safety Analysis Report (SAR) design-basis accident envelops process-specific accidents; and support future change control activities.

    As administrators evaluate potential approaches to improve cost, quality, and throughput efficiencies in the emergency department (ED), "front-end" operations become an important area of focus. Interventions such as immediate bedding, bedside registration, advanced triage (triage-based care) protocols, physician/practitioner at triage, dedicated "fast track" service line, tracking systems and whiteboards, wireless communication devices, kiosk self check-in, and personal health record technology ("smart cards") have been offered as potential solutions to streamline the front-end processing of ED patients, which becomes crucial during periods of full capacity, crowding, and surges. Although each of these operational improvement strategies has been described in the lay literature, various reports exist in the academic literature about their effect on front-end operations. In this report, we present a review of the current body of academic literature, with the goal of identifying select high-impact front-end operational improvement solutions.

    A set of standard operating procedures (SOPs) provides a clinical research department with clear roles, responsibilities, and processes to ensure compliance, accuracy, and timeliness of data. SOPs also serve as a standardized training program for new employees. A practice may have an employee that can assist in the development of SOPs. There are also consultants that specialize in working with a practice to develop and write practice-specific SOPs. Making SOPs a priority will save a practice time and money in the long run and make the research practice more attractive to corporate study sponsors.

    This report documents the methodology, computational framework, and results of facility accident analyses performed for the US Department of Energy (DOE) Waste Management Programmatic Environmental Impact Statement (WM PEIS). The accident sequences potentially important to human health risk are specified, their frequencies assessed, and the resultant radiological and chemical source terms evaluated. A personal-computer-based computational framework and database have been developed that provide these results as input to the WM PEIS for the calculation of human health risk impacts. The WM PEIS addresses management of five waste streams in the DOE complex: low-level waste (LLW), hazardous waste (HW), high-level waste (HLW), low-level mixed waste (LLMW), and transuranic waste (TRUW). Currently projected waste generation rates, storage inventories, and treatment process throughputs have been calculated for each of the waste streams. This report summarizes the accident analyses and aggregates the key results for each of the waste streams. Source terms are estimated, and results are presented for each of the major DOE sites and facilities by WM PEIS alternative for each waste stream. Key assumptions in the development of the source terms are identified. The appendices identify the potential atmospheric release of each toxic chemical or radionuclide for each accident scenario studied. They also discuss specific accident analysis data and guidance used or consulted in this report.

  6. Emergency department triage: an ethical analysis

    Directory of Open Access Journals (Sweden)

    2011-10-01

    Full Text Available Abstract Background Emergency departments across the globe follow a triage system in order to cope with overcrowding. The intention behind triage is to improve the emergency care and to prioritize cases in terms of clinical urgency. Discussion In emergency department triage, medical care might lead to adverse consequences like delay in providing care, compromise in privacy and confidentiality, poor physician-patient communication, failing to provide the necessary care altogether, or even having to decide whose life to save when not everyone can be saved. These consequences challenge the ethical quality of emergency care. This article provides an ethical analysis of "routine" emergency department triage. The four principles of biomedical ethics - viz. respect for autonomy, beneficence, nonmaleficence and justice provide the starting point and help us to identify the ethical challenges of emergency department triage. However, they do not offer a comprehensive ethical view. To address the ethical issues of emergency department triage from a more comprehensive ethical view, the care ethics perspective offers additional insights. Summary We integrate the results from the analysis using four principles of biomedical ethics into care ethics perspective on triage and propose an integrated clinically and ethically based framework of emergency department triage planning, as seen from a comprehensive ethics perspective that incorporates both the principles-based and care-oriented approach.

  12. Assessment of academic departments efficiency using data envelopment analysis

    Directory of Open Access Journals (Sweden)

    Salah R. Agha

    2011-07-01

    Full Text Available Purpose: In this age of knowledge economy, universities play an important role in the development of a country. As government subsidies to universities have been decreasing, more efficient use of resources becomes important for university administrators. This study evaluates the relative technical efficiencies of academic departments at the Islamic University in Gaza (IUG during the years 2004-2006. Design/methodology/approach: This study applies Data Envelopment Analysis (DEA to assess the relative technical efficiency of the academic departments. The inputs are operating expenses, credit hours and training resources, while the outputs are number of graduates, promotions and public service activities. The potential improvements and super efficiency are computed for inefficient and efficient departments respectively. Further, multiple linear -regression is used to develop a relationship between super efficiency and input and output variables.Findings: Results show that the average efficiency score is 68.5% and that there are 10 efficient departments out of the 30 studied. It is noted that departments in the faculty of science, engineering and information technology have to greatly reduce their laboratory expenses. The department of economics and finance was found to have the highest super efficiency score among the efficient departments. Finally, it was found that promotions have the greatest contribution to the super efficiency scores while public services activities come next.Research limitations/implications: The paper focuses only on academic departments at a single university. Further, DEA is deterministic in nature.Practical implications: The findings offer insights on the inputs and outputs that significantly contribute to efficiencies so that inefficient departments can focus on these factors.Originality/value: Prior studies have used only one type of DEA (BCC and they did not explicitly answer the question posed by the inefficient

    Ollerton, J E; Hodgetts, T J

    2010-03-01

    This paper analyses all ophthalmic attendances to a deployed emergency department (ED) in Iraq to identify patterns of injury to optimise patient care, plan equipment tables for future operations and emphasise need for prevention of ocular morbidity. The Academic Department of Military Emergency Medicine at the Royal Centre for Defence Medicine in Birmingham maintains an electronic database with derails on all attendances to the emergency departments deployed on Operations. This Operational Emergency Department Attendance Register (OpEDAR) was searched for all patients with medical classification of Ophthalmology over a 52 month period between 1 March 2003 and 30 June 2007. During this period 30,195 patients were seen in the ED on Operation Telic and are available for analysis. Patients with ophthalmic complaints account for 5.3% of all presentations to the ED and rank as the 7th most common reason for attendance. This paper identifies patterns of injury to enable future planning of equipment tables and identifies the need for prevention of injury wherever possible. Implications on days lost from full active duty for the injured can be extrapolated. More data needs to be collated on the use of eye protection and the relevance of contact lenses in deployed personnel with eye injuries.

    1994-06-01

    The U.S. Department of Energy, Nevada Operations Office (DOE/NV), Completion Report provides a summary of activities conducted at the Nevada Test Site (NTS) between October 1, 1992, and September 30, 1993, associated with Operation KLAXON. (In the past, each annual Completion Report dealt with a series of underground nuclear detonations; however, because no nuclear tests were conducted during FY 1993, this Report summarizes continuing nonnuclear and nuclear test readiness activities at the NTS sponsored by DOE/NV.) The report serves as a reference for those involved with the planning and execution of Operation KLAXON and also serves as a planning guide for future operations. Information in the report covers the logistics and management of activities. Scientific information and data associated with NTS activities are presented in technical documents published by participating agencies. In September 1992, Congress legislated a nine-month moratorium on the testing of nuclear weapons. The bill also provided for a resumption of testing (with no more than five tests per year, or a total of 15 during the next three years) in July 1993, and mandated an end to nuclear testing, entirely, by 1996. President Bush signed the bill into law in October 1992.

    To determine the number, status and nature of emergency department attendances to deployed field hospitals. All attendances to the emergency department (ED) of deployed field hospitals in support of Operation TELIC (Iraq) from initial entry war fighting to enduring operations. Analysis of hand written and electronic registers ED attendance registers and validation with four other data sources. Validation of data held on OpEDAR against 4 other data sources shows that OpEDAR is accurate, but that accuracy can be further improved. 26,746 ED attendances recorded on OP TELIC from 19 March 2003 to 11 November 2006. 21,112 (78.9%) were UK military. Overall, 43.5% were admitted from ED. Attendances peaked during TELIC phases 2 (422.9 per 1,000 troops deployed), but have settled to around 200 per 1,000 troops deployed in the more recent phases. Ophthalmology rates peaked in TELIC 2 to 20.72 per 1,000 and have since reduced to a consistent 10 to 15 per 1,000. This suggests that preventative measures introduced for eye injury are incompletely effective or incompletely utilised. OpEDAR is a clinical tool to inform manning, equipment and training requirements for enduring and new operations, focused on the requirements of the emergency department. Multivariate quality control models applied in industry could be applied to OpEDAR to produce a dynamic epidemiological tool that identifies emerging case clusters and facilitates deployed commanders to take preventative action.

    A total of 6.05 x 10{sup 7} gal of liquid waste was decontaminated by the Process Waste Treatment Plant (PWTP) ion exchange system during CY 1992. This averaged to 115 gpm throughout the year. When necessary, a wastewater sidestream of 50--80 gpm was treated through the use of a natural zeolite treatment system. An additional 8.00 x 10{sup 6} gal (average of 15 gpm throughout the year) were treated by the zeolite system. Therefore, the average total flow treated at the PWTP for CY 1992 was 130 gpm. In mid-June, the zeolite system was repiped to allow it the capability to treat the ion exchange system`s discharge due to rising Cs problems in the wastewater. While being used to treat the ion exchange system`s discharge, it cannot treat a sidestream of wastewater. During the year, the regeneration of the cation exchange resins resulted in the generation of 7.83 x 10{sup 3} gal of liquid low-level waste (LLLW) concentrate and 1.15 x 10{sup 4} gal of LLLW evaporator feed. The head-end softening process (precipitation/clarification) generated 604 drums (4.40 x 10{sup 3} ft{sup 3}) of solid low-level waste sludge. The zeolite treatment system generated approximately 8.40 x 10{sup 2} ft{sup 3} of spent zeolite resin, which was turned over to the Solid Waste Operations Department for disposal. See Table 1 for a monthly summary of activities at the PWTP. Figures 1, 2, 3, and 4 show a comparison of operations at the PWTP in 1992 with previous years. Figure 5 shows a comparison of annual rainfall at Oak Ridge National Laboratory (ORNL) since 1987. A total of 1.55 x 10{sup 8} gal of liquid waste (average of 294 gpm throughout the year) was treated at the Nonradiological Wastewater Treatment Plant (NRWTP). Of this amount, 1.40 x 10{sup 7} gal were treated by the precipitation/clarification process for removal of heavy metals. Twenty-five boxes (1.60 x 10{sup 3} ft{sup 3}) of solid sludge generated by the precipitation/clarification process were removed from the filter press room.

    Hemodynamic modifications induced by general anesthesia could lead to underestimation of mitral regurgitation (MR) severity in the operating department and potentially serious consequences. The intraoperative severity of MR was prospectively compared with the preoperative baseline evaluation using dynamic quantitative transesophageal echocardiography in 25 patients who were stable with MR 2/4 or greater undergoing coronary bypass, mitral valve operation, or both. Significant changes in the severity of MR using transesophageal echocardiographic criteria occurred after the induction of general anesthesia and with phenylephrine. Quantitative transesophageal echocardiographic evaluation of MR using effective orifice area and vena contracta, and the use of phenylephrine challenge, were useful to avoid underestimating MR severity in the operating department.

    The objective was to obtain a commitment to adopt a common set of definitions for emergency department (ED) demographic, clinical process, and performance metrics among the ED Benchmarking Alliance (EDBA), ED Operations Study Group (EDOSG), and Academy of Academic Administrators of Emergency Medicine (AAAEM) by 2017. A retrospective cross-sectional analysis of available data from three ED operations benchmarking organizations supported a negotiation to use a set of common metrics with identical definitions. During a 1.5-day meeting-structured according to social change theories of information exchange, self-interest, and interdependence-common definitions were identified and negotiated using the EDBA's published definitions as a start for discussion. Methods of process analysis theory were used in the 8 weeks following the meeting to achieve official consensus on definitions. These two lists were submitted to the organizations' leadership for implementation approval. A total of 374 unique measures were identified, of which 57 (15%) were shared by at least two organizations. Fourteen (4%) were common to all three organizations. In addition to agreement on definitions for the 14 measures used by all three organizations, agreement was reached on universal definitions for 17 of the 57 measures shared by at least two organizations. The negotiation outcome was a list of 31 measures with universal definitions to be adopted by each organization by 2017. The use of negotiation, social change, and process analysis theories achieved the adoption of universal definitions among the EDBA, EDOSG, and AAAEM. This will impact performance benchmarking for nearly half of US EDs. It initiates a formal commitment to utilize standardized metrics, and it transitions consistency in reporting ED operations metrics from consensus to implementation. This work advances our ability to more accurately characterize variation in ED care delivery models, resource utilization, and performance. In

    This study examined the effectiveness of Public Law 110-181, "National Defense Authorization Act of Fiscal Year 2008, Title XVI-Wounded Warriors Matter," as it relates to health care for returning Operation Enduring Freedom and Operation Iraqi Freedom (OEF/OIF) combat veterans. Specifically, it examined the gap between the time an OEF/OIF combat service member left active service and subsequently obtained health care within the Veteran Affairs (VA) Healthcare System, and which factors influenced or impeded the veteran from obtaining health care sooner. Data were collected from 376 OEF/OIF combat veterans who sought health care at the Nashville or Murfreesboro VA Medical Centers. A questionnaire was designed exclusively for this study. The average time gap for an OEF/OIF combat veteran to transition from Department of Defense to VA health care was 3.83 months (SD 7.17). Twenty-six percent of respondents reported there were factors that impeded them from coming to the VA sooner. Factors included lack of knowledge about VA benefits, transportation/distance, perceptions of losing military career, seeking help as sign of weakness, and VA reputation. The study provided some evidence to support that Department of Defense and VA are meeting mandates for providing seamless transition of health care set forth by "Public Law 110-181, National Defense Authorization Act of Fiscal Year 2008."

    This document reports on the design and operation of a high-capacity and high-penetration-ratio microgrid, which consists of 19 photovoltaic-powered residential houses designed by collegiate teams as part of their participation in the U.S. Department of Energy Solar Decathlon 2013. The microgrid was interconnected with the local utility, and resulting net-power and power-quality events were recorded in high detail (1-minute data sampling or better). Also, a controlled-island operation test was conducted to evaluate the microgrid response to additional events such as increased loads (e.g., from electric vehicles) and bypassing of voltage regulators. This temporary ground-laid microgrid was stable under nominal and island-operation conditions; adverse weather and loads did not lead to power-quality degradation.

  19. Accreditation and quality approach in operating theatre departments: the French approach.

    Science.gov (United States)

    Soudée, M

    2005-01-01

    Since 1996, French health establishments are subjected to a process of evaluating the quality of care, called "accreditation". This process was controlled by ANAES, which, after January 1st, 2005 became the Haute Autorité de Santé (HAS). The accreditation is characterized by a dual process of self-assessment and external audit, leading to four levels of accreditation. In spite of requiring a time-consuming methodology, this approach provides an important means of consolidating the development of the quality approach and re-stimulating the compliance of establishments with standards of safety and vigilance. The professional teams of many French operating theatre departments have been able to use the regulatory and restricting framework of accreditation to organize quality approaches specific to the operative system, supported by the organizational structures of the department such as the operating suite committee, departmental boards and the steering group. Based on quality guidelines including a commitment from the manager and operating suite committee, as well as a quality flow chart and a quality system, these teams describe the main procedures for running the operating theatre. They also organize the follow-up of incidents and undesirable events, along with the risks and points to watch. Audits of the operative system are planned on a regular basis. The second version of the accreditation process considerably reinforces the assessment of professional practices by evaluating the relevance, the risks and the methods of managing care for pathologies. It will make it possible to implement assessments of the health care provided by operating theatre departments and will reinforce the importance of search for quality.

    In order to minimize the loss of bone and muscle mass during spaceflight, the Multi-purpose Crew Vehicle (MPCV) will include an exercise device and enough free space within the cabin for astronauts to use the device effectively. The NASA Digital Astronaut Project (DAP) has been tasked with using computational modeling to aid in determining whether or not the available operational volume is sufficient for in-flight exercise.Motion capture data was acquired using a 12-camera Smart DX system (BTS Bioengineering, Brooklyn, NY), while exercisers performed 9 resistive exercises without volume restrictions in a 1g environment. Data were collected from two male subjects, one being in the 99th percentile of height and the other in the 50th percentile of height, using between 25 and 60 motion capture markers. Motion capture data was also recorded as a third subject, also near the 50th percentile in height, performed aerobic rowing during a parabolic flight. A motion capture system and algorithms developed previously and presented at last years HRP-IWS were utilized to collect and process the data from the parabolic flight [1]. These motions were applied to a scaled version of a biomechanical model within the biomechanical modeling software OpenSim [2], and the volume sweeps of the motions were visually assessed against an imported CAD model of the operational volume. Further numerical analysis was performed using Matlab (Mathworks, Natick, MA) and the OpenSim API. This analysis determined the location of every marker in space over the duration of the exercise motion, and the distance of each marker to the nearest surface of the volume. Containment of the exercise motions within the operational volume was determined on a per-exercise and per-subject basis. The orientation of the exerciser and the angle of the footplate were two important factors upon which containment was dependent. Regions where the exercise motion exceeds the bounds of the operational volume have been

    In this study, a statistical analysis is performed by model the variations of the disabled about 0-19 years old population among French departments. The aim is to classify the departments according to their profile determinants (socioeconomic and behavioural profiles). The analysis is focused on two types of methods: principal component analysis (PCA) and multiple correspondences factorial analysis (MCA) to review which one is the best methods for interpretation of the correlation between the determinants of disability (independent variable). The PCA is the best method for interpretation of the correlation between the determinants of disability (independent variable). The PCA reduces 14 determinants of disability to 4 axes, keeps 80% of total information, and classifies them into 7 classes. The MCA reduces the determinants to 3 axes, retains only 30% of information, and classifies them into 4 classes.

    2010-01-01

    Full Text Available Problem statement: The purpose of this study is to analyze efficiency and benchmarking using Data Envelopment Analysis (DEA in departments of University. Benchmarking is a process of defining valid measures of performance comparison among peer decision making units (DMUs, using them to determine the relative positions of the peer DMUs and, ultimately, establishing a standard of excellence. Approach: DEA can be regarded as a benchmarking tool, because the frontier identified can be regarded as an empirical standard of excellence. Once the frontier is established, then one may compare a set of DMUs to the frontier. Results: We apply benchmarking to detect mistakes of inefficient departments to become efficient and to learn better managerial practice. Conclusion: The results indicated 9 departments are inefficient between 21 departments. The average inefficiency is 0.8516. Inefficient departments dont have excess in the number of teaching staff, but all of them have excess the number of registered student. The shortage of performed research works is the most important indicators of outputs in inefficient departments, which must be corrected.

  5. Fully automated (operational) modal analysis

    Science.gov (United States)

    Reynders, Edwin; Houbrechts, Jeroen; De Roeck, Guido

    2012-05-01

    Modal parameter estimation requires a lot of user interaction, especially when parametric system identification methods are used and the modes are selected in a stabilization diagram. In this paper, a fully automated, generally applicable three-stage clustering approach is developed for interpreting such a diagram. It does not require any user-specified parameter or threshold value, and it can be used in an experimental, operational, and combined vibration testing context and with any parametric system identification algorithm. The three stages of the algorithm correspond to the three stages in a manual analysis: setting stabilization thresholds for clearing out the diagram, detecting columns of stable modes, and selecting a representative mode from each column. An extensive validation study illustrates the accuracy and robustness of this automation strategy.

    The consensus conference on "Advancing Research in Emergency Department (ED) Operations and Its Impact on Patient Care," hosted by The ED Operations Study Group (EDOSG), convened to craft a framework for future investigations in this important but understudied area. The EDOSG is a research consortium dedicated to promoting evidence-based clinical practice in emergency medicine. The consensus process format was a modified version of the NIH Model for Consensus Conference Development. Recommendations provide an action plan for how to improve ED operations study design, create a facilitating research environment, identify data measures of value for process and outcomes research, and disseminate new knowledge in this area. Specifically, we call for eight key initiatives: 1) the development of universal measures for ED patient care processes; 2) attention to patient outcomes, in addition to process efficiency and best practice compliance; 3) the promotion of multisite clinical operations studies to create more generalizable knowledge; 4) encouraging the use of mixed methods to understand the social community and human behavior factors that influence ED operations; 5) the creation of robust ED operations research registries to drive stronger evidence-based research; 6) prioritizing key clinical questions with the input of patients, clinicians, medical leadership, emergency medicine organizations, payers, and other government stakeholders; 7) more consistently defining the functional components of the ED care system, including observation units, fast tracks, waiting rooms, laboratories, and radiology subunits; and 8) maximizing multidisciplinary knowledge dissemination via emergency medicine, public health, general medicine, operations research, and nontraditional publications. © 2015 by the Society for Academic Emergency Medicine.

    This Environmental Monitoring Plan was prepared for the US Department of Energy`s (DOE`s) Richland Operations Office (RL) to implement the requirements of DOE Order 5400.1. According to the Order, each DOE site, facility, or activity that uses, generates, releases, or manages significant pollutants or hazardous materials shall prepare a written environmental monitoring plan covering two major activities: (1) effluent monitoring and (2) environmental surveillance. The plan is to contain information discussing the rationale and design criteria for the monitoring programs, sampling locations and schedules, quality assurance requirements, program implementation procedures, analytical procedures, and reporting requirements. The plan`s purpose is to assist DOE in the management of environmental activities at the Hanford Site and to help ensure that operations on the site are conducted in an environmentally safe and sound manner.

    Hospital-based emergency departments (EDs), given their high cost and major role in allocating care resources, are at the center of the debate about how to maximize value in delivering health care in the United States. To operate effectively and create value, EDs must be flexible, having the ability to rapidly adapt to the highly variable needs of patients. The concept of flexibility has not been well described in the ED literature. We introduce the concept, outline its potential benefits, and provide some illustrative examples to facilitate incorporating flexibility into ED management. We draw on operations research and organizational theory to identify and describe 5 forms of flexibility: physical, human resource, volume, behavioral, and conceptual. Each form of flexibility may be useful individually or in combination with other forms in improving ED performance and enhancing value. We also offer suggestions for measuring operational flexibility in the ED. A better understanding of operational flexibility and its application to the ED may help us move away from reactive approaches of managing variable demand to a more systematic approach. We also address the tension between cost and flexibility and outline how "partial flexibility" may help resolve some challenges. Applying concepts of flexibility from other disciplines may help clinicians and administrators think differently about their workflow and provide new insights into managing issues of cost, flow, and quality in the ED.

    Full Text Available Veteran activity levels may decrease between Active Duty and postdeployment. We examined attitudes and changes in self-reported activities between the two in Operation Iraqi Freedom/Operation Enduring Freedom (OIF/OEF veterans using Department of Veterans Affairs (VA services. We conducted an online cross-sectional survey (June-August 2008 of postdeployment OIF/OEF veterans registered with the VA Ann Arbor Healthcare System, Ann Arbor, Michigan. Descriptive statistics summarized demographic data and attitudes, while regression analyses compared physical activities during Active Duty with physical activities postdeployment. Participants (n = 319, 15.6% response rate reported that they believe staying physically fit is important, they worry about gaining weight, and they believe exercise will keep them healthy (77%, 72%, and 90% agree or strongly agree, respectively. Running (30.0%, Exercise with Gym Equipment (21.5%, Occupational Activities (14.9%, and Walking (13.0% were the most frequently reported Active Duty physical activities. The most frequently reported postdeployment physical activities included Walking (21.1%, Running (18.5%, and Exercise with Gym Equipment (17.9%. Health problems (39% and chronic pain (52% were common barriers to physical activity. Postdeployment OIF/OEF veterans using the VA believe physical activity is beneficial, yet many report health problems and/or chronic pain that makes exercise difficult. Physical activity promotes health, and strategies are needed to facilitate physical activity in this population.

    In response to increasing demands some emergency departments have introduced transdisciplinary care coordination teams. Such teams comprise staff from multiple disciplines who are trained to perform roles outside their usual scope of practice. This study aimed to critically evaluate the patient, carer and ED staff perceptions of the transdisciplinary model of care in an emergency department in a Melbourne metropolitan hospital. The evaluation of the transdisciplinary team involved interviews with patients and carers who have received the transdisciplinary team services, and focus groups with emergency nursing and transdisciplinary team staff. Analysis of the data revealed that the transdisciplinary model provided an essential service, where staff members were capable of delivering care across all disciplines. The ability to perform comprehensive patient assessments ensured safe discharge, with follow-up services in place. The existence of this team was seen to free up time for the emergency nursing staff, enabling them to see other patients, and improving department efficiency while providing quality care and increasing staff satisfaction. This study identified several important factors which contributed to the success of the transdisciplinary team, which was well integrated into the larger emergency department team.

    Full Text Available In the petroleum, natural gas and petrochemical industries, great attention is being paid to safety, reliability and maintainability of equipment. There are a number of technologies to monitor, control, and maintain gas, oil, water, and sewer pipelines. The paper focuses on operational modal analysis (OMA application for condition monitoring of operating pipelines. Special focus is on the topicality of OMA for definition of the dynamic features of the pipeline (frequencies and mode shapes in operation. The research was conducted using two operating laboratory models imitated a part of the operating pipeline. The results of finite-element modeling, identification of pipe natural modes and its modification under the influence of virtual failure are discussed. The work considers the results of experimental research of dynamic behavior of the operating pipe models using one of OMA techniques and comparing dynamic properties with the modeled data. The study results demonstrate sensitivity of modal shape parameters to modification of operating pipeline technical state. Two strategies of pipeline repair – with continuously condition-based monitoring with proposed technology and without such monitoring, was discussed. Markov chain reliability models for each strategy were analyzed and reliability improvement factor for proposed technology of monitoring in compare with traditional one was evaluated. It is resumed about ability of operating pipeline condition monitoring by measuring dynamic deformations of the operating pipe and OMA techniques application for dynamic properties extraction.

    1995-05-01

    This paper communicates the operational implementation of filmless digital radiology in clinical routine, its feasibility and its effect on the radiology profession, based on the three years clinical experience from the filmless digital radiology department of the Danube Hospital, a major teaching hospital in Vienna, Austria, with currently 850 acute-care beds. Since April 1992 all radiological modalities are reported from the monitors of 16 reporting consoles in the radiology department. Images and reports are distributed by the hospital-wide network (Sienet, Siemens Medical Systems, Erlangen), and can be viewed on 60 display consoles throughout the hospital. Filmless radiology primarily is an efficient hospital-wide infrastructure to deliver radiological services along with other medical information, providing safe and fast access to this information anytime and anywhere, necessary for the conduct of the diagnostic and therapeutic task of patient care. In a comparative study of the Danube Hospital with the film based Rudolfstiftung Hospital in Vienna, we found a significant decrease of the mean patient length of hospital stay (1.99 to 3.72 days) that partially might be attributed to the implementation of filmless radiology.

    The objective of the ``Repository Operational Criteria (ROC) Feasibility Studies`` (or ROC task) was to conduct comprehensive and integrated analyses of repository design, construction, and operations criteria in 10 CFR Part 60 regulations considering the interfaces among the components of the regulations and impacts of any potential changes to those regulations. The ROC task addresses regulatory criteria and uncertainties related to the preclosure aspects of the geologic repository. Those parts of 10 CFR Part 60 that require routine guidance or minor changes to the rule were addressed in Hageman and Chowdhury, 1992. The ROC task shows a possible need for further regulatory clarity, by major changes to the rule, related to the design bases and siting of a geologic repository operations area and radiological emergency planning in order to assure defense-in-depth. The analyses, presented in this report, resulted in the development and refinement of regulatory concepts and their supporting rationale for recommendations for potential major changes to 10 CFR Pan 0 regulations.

    In (operational) modal analysis the modal parameters of a structure are identified from the response of that structure to (unmeasurable operational) perturbations. A key issue that remains to be solved is the calculation of uncertainty bounds on the estimated modal parameters. The present paper fills this gap. The theory is illustrated by means of a simulation and a real measurement example (operational modal analysis of a bridge).

    2011-01-01

    Operational Modal Analysis (OMA) is one of the branches of experimental modal analysis which allows extracting modal parameters based on measuring only the responses of a structure under ambient or operational excitation which is not needed to be measured. This makes OMA extremely attractive...... to modal analysis of big structures such as wind turbines where providing measured excitation force is an extremely difficult task. One of the main OMA assumption concerning the excitation is that it is distributed randomly both temporally and spatially. Obviously, closer the real excitation...... is to the assumed one, better modal parameter estimation one can expect. Traditionally, wind excitation is considered as a perfect excitation obeying the OMA assumptions. However, the present study shows that the aeroelastic phenomena due to rotor rotation dramatically changes the character of aerodynamic...

    This study aims to determine the best resource allocation and to increase the efficiency service of an emergency department in a public hospital in Kuala Lumpur. We integrate Discrete Event Simulation (DES) and three models of Data Envelopment Analysis (DEA); Input-oriented CCR model, Input-oriented BCC model and Super-Efficiency model to fulfill such objective. Based on the comparison of results taken from the DEA models, the combination of DES, Input-oriented BCC model and Super-Efficiency BCC model is seen to be the best resource allocation technique to be used for enhancing the hospital efficiency. The combination has reduced patients waiting time while improving the average utilization rate of hospital resources compared to the current situation.

    Euclidean Clifford analysis is a higher dimensional function theory centred around monogenic functions,i.e.,null solutions to a first order vector valued rotation invariant differential operator (θ) called the Dirac operator.More recently,Hermitian Clifford analysis has emerged as a new branch,offering yet a refinement of the Euclidean case; it focuses on the simultaneous null solutions,called Hermitian monogenic functions,to two Hermitian Dirac operators (θ)z_ and (θ)z_(+) which are invariant under the action of the unitary group.In Euclidean Clifford analysis,the Teodorescu operator is the right inverse of the Dirac operator (θ).In this paper,Teodorescu operators for the Hermitian Dirac operators (θ)z_ and (θ)z(+) are constructed.Moreover,the structure of the Euclidean and Hermitian Teodorescu operators is revealed by analyzing the more subtle behaviour of their components.Finally,the obtained inversion relations are still refined for the differential operators issuing from the Euclidean and Hermitian Dirac operators by splitting the Clifford algebra product into its dot and wedge parts.Their relationship with several complex variables theory is discussed.

    This annual report is prepared pursuant to the National Emission Standards for Hazardous Air Pollutants (NESHAPs; Title 40 Code of Federal Regulations [CFR] Part 61, Subpart H). Subpart H governs radionuclide emissions to air from Department of Energy (DOE) facilities. NESHAPs limits the emission of radionuclides to the ambient air from DOE facilities to levels resulting in an annual effective dose equivalent (EDE) of 10 mrem (100 {micro}Sv) to any member of the public. The EDEs for the Lawrence Livermore National Laboratory (LLNL) site-wide maximally exposed members of the public from operations in 2005 are summarized here. Livermore site: 0.0065 mrem (0.065 {micro}Sv) (41% from point source emissions, 59% from diffuse source emissions). The point source emissions include gaseous tritium modeled as tritiated water vapor as directed by EPA Region IX; the resulting dose is used for compliance purposes. Site 300: 0.018 mrem (0.18 {micro}Sv) (48% from point source emissions, 52% from diffuse source emissions). The EDEs were calculated using the EPA-approved CAP88-PC air dispersion/dose-assessment model, except for doses for two diffuse sources that were estimated using measured radionuclide concentrations and dose coefficients. Specific inputs to CAP88-PC for the modeled sources included site-specific meteorological data and source emissions data, the latter variously based on continuous stack effluent monitoring data, stack flow or other release-rate information, ambient air monitoring data, and facility knowledge.

    Climate change challenges many of the basic assumptions routinely used by conservation planners and managers, including the identification and prioritization of areas for conservation based on current environmental conditions and the assumption those conditions could be controlled by management actions. Climate change will likely alter important ecosystem drivers (temperature, precipitation, and sea-level rise) and make it difficult, if not impossible, to maintain current environmental conditions into the future. Additionally, the potential for future conservation of non-conservation lands may be affected by climate change, which further complicates resource planning. Potential changes to ecosystem drivers, as a result of climate change, highlight the need to develop and adapt effective conservation strategies to cope with the effects of climate and landscape change. The U.S. Congress, recognized the potential effects of climate change and authorized the creation of the U.S. Geological Survey National Climate Change and Wildlife Science Center (NCCWSC) in 2008. The directive of the NCCWSC is to produce science that supports resource-management agencies as they anticipate and adapt to the effects of climate change on fish, wildlife, and their habitats. On September 14, 2009, U.S. Department of the Interior (DOI) Secretary Ken Salazar signed Secretarial Order 3289 (amended February 22, 2010), which expanded the mandate of the NCCWSC to address climate-change-related impacts on all DOI resources. Secretarial Order 3289 "Addressing the Impacts of Climate Change on America's Water, Land, and Other Natural and Cultural Resources," established the foundation of two partner-based conservation science entities: Climate Science Centers (CSC) and their primary partners, Landscape Conservation Cooperatives (LCC). CSCs and LCCs are the Department-wide approach for applying scientific tools to increase the understanding of climate change, and to coordinate an effective response

    With increasing deployment, complexity, and sophistication of equipment and related processes within the clinical imaging environment, system failures are more likely to occur. These failures may have varying effects on the patient, ranging from no harm to devastating harm. Failure mode and effect analysis (FMEA) is a tool that permits the proactive identification of possible failures in complex processes and provides a basis for continuous improvement. This overview of the basic principles and methodology of FMEA provides an explanation of how FMEA can be applied to clinical operations in a radiology department to reduce, predict, or prevent errors. The six sequential steps in the FMEA process are explained, and clinical magnetic resonance imaging services are used as an example for which FMEA is particularly applicable. A modified version of traditional FMEA called Healthcare Failure Mode and Effect Analysis, which was introduced by the U.S. Department of Veterans Affairs National Center for Patient Safety, is briefly reviewed. In conclusion, FMEA is an effective and reliable method to proactively examine complex processes in the radiology department. FMEA can be used to highlight the high-risk subprocesses and allows these to be targeted to minimize the future occurrence of failures, thus improving patient safety and streamlining the efficiency of the radiology department.

    2006-06-01

    Since the emergence of digital imaging, there have been questions about the necessity of continuing reject analysis programs in imaging departments to evaluate performance and quality. As a marketing strategy, most suppliers of digital technology focus on the supremacy of the technology and its ability to reduce the number of repeats, resulting in less radiation doses given to patients and increased productivity in the department. On the other hand, quality assurance radiographers and radiologists believe that repeats are mainly related to positioning skills, and repeat analysis is the main tool to plan training needs to up-skill radiographers. A comparative study between conventional and digital imaging was undertaken to compare outcomes and evaluate the need for reject analysis. However, digital technology still being at its early development stages, setting a credible reject analysis program became the major task of the study. It took the department, with the help of the suppliers of the computed radiography reader and the picture archiving and communication system, over 2 years of software enhancement to build a reliable digital repeat analysis system. The results were supportive of both philosophies; the number of repeats as a result of exposure factors was reduced dramatically; however, the percentage of repeats as a result of positioning skills was slightly on the increase for the simple reason that some rejects in the conventional system qualifying for both exposure and positioning errors were classified as exposure error. The ability of digitally adjusting dark or light images reclassified some of those images as positioning errors.

    Human reliability is the probability that a person correctly performs some system required action in a required time period and performs no extraneous action that can degrade the system Human reliability analysis (HRA) is the analysis, prediction and evaluation of work-oriented human performance using some indices as human error likelihood and probability of task accomplishment. Significant progress has been made in the HRA field during the last years, mainly in nuclear area. Some first-generation HRA methods were developed, as THERP (Technique for human error rate prediction). Now, an array of called second-generation methods are emerging as alternatives, for instance ATHEANA (A Technique for human event analysis). The ergonomics approach has as tool the ergonomic work analysis. It focus on the study of operator's activities in physical and mental form, considering at the same time the observed characteristics of operator and the elements of the work environment as they are presented to and perceived by the operators. The aim of this paper is to propose a methodology to analyze the human reliability of the operators of industrial plant control room, using a framework that includes the approach used by ATHEANA, THERP and the work ergonomics analysis.

    2011-01-01

    Spreadsheet technology is a cornerstone of IT systems in most organisations. It is often the glue that binds more structured transaction-based systems together. Financial operations are a case in point where spreadsheets fill the gaps left by dedicated accounting systems, particularly covering reporting and business process operations. However, little is understood as to the nature of spreadsheet usage in organisations and the contents and structure of these spreadsheets as they relate to key business functions with few, if any, comprehensive analyses of spreadsheet repositories in real organisations. As such this paper represents an important attempt at profiling real and substantial spreadsheet repositories. Using the Luminous technology an analysis of 65,000 spreadsheets for the financial departments of both a government and a private commercial organisation was conducted. This provides an important insight into the nature and structure of these spreadsheets, the links between them, the existence and natur...

    The overall objective of this project is to conduct cost analyses and estimate costs for on- and off-board hydrogen storage technologies under development by the U.S. Department of Energy (DOE) on a consistent, independent basis. This can help guide DOE and stakeholders toward the most-promising research, development and commercialization pathways for hydrogen-fueled vehicles. A specific focus of the project is to estimate hydrogen storage system cost in high-volume production scenarios relative to the DOE target that was in place when this cost analysis was initiated. This report and its results reflect work conducted by TIAX between 2004 and 2012, including recent refinements and updates. The report provides a system-level evaluation of costs and performance for four broad categories of on-board hydrogen storage: (1) reversible on-board metal hydrides (e.g., magnesium hydride, sodium alanate); (2) regenerable off-board chemical hydrogen storage materials(e.g., hydrolysis of sodium borohydride, ammonia borane); (3) high surface area sorbents (e.g., carbon-based materials); and 4) advanced physical storage (e.g., 700-bar compressed, cryo-compressed and liquid hydrogen). Additionally, the off-board efficiency and processing costs of several hydrogen storage systems were evaluated and reported, including: (1) liquid carrier, (2) sodium borohydride, (3) ammonia borane, and (4) magnesium hydride. TIAX applied a bottom-up costing methodology customized to analyze and quantify the processes used in the manufacture of hydrogen storage systems. This methodology, used in conjunction with ® software and other tools, developed costs for all major tank components, balance-of-tank, tank assembly, and system assembly. Based on this methodology, the figure below shows the projected on-board high-volume factory costs of the various analyzed hydrogen storage systems, as designed. Reductions in the key cost drivers may bring hydrogen storage system costs closer to this DOE target

    Full Text Available Background. Optimization of health care financing under current standards of treatment can be achieved by determining the factors that affect the number of hospital admissions at emergency departments (ED, and their significance. Objectives . Identification of factors determining hospitalizations at emergency department. Material and methods . The study involved 150 emergency department patients in Kedzierzyn-Kozle. An original questionnaire, the Health Behaviors Inventory, and a modified version of the Camberwell Assessment of Need Short Appraisal Schedule (CANSAS were used. Results. At greatest risk of hospitalization are those patients who: take more than 4 drugs (OR 12.17, 95% CI 2.97–73.67; are being treated for chronic diseases (OR 5.37, 95% CI 2.56–11.62; are above 44.5 years of age (OR 3.14, 95% CI 1.54–6.51; are being treated at an outpatient specialist clinic (OR 3.87, 95% CI 1.85–8.32; have a BMI above 27.1 (OR 2.84, 95% CI 1.39–5.88; have at most average material status (OR 0.42, 95% CI 0.20–0.87; have symptoms of severity greater than 5 (OR 2.23, 95% CI 1.11–4.55; and have a low index of unsatisfied needs (a Camberwell index lower than 0.825: OR 0.36, 95% CI 0.17–0.72. Conclusions . Any program to prevent hospitalization should be based on the measurement of health behavior, should focus on promoting knowledge of chronic diseases and the means of preventing them, and should involve patient education on the purpose of emergency departments. It is necessary to strive for increase responsiveness of healthcare to patients’ needs and to support the area of primary-care-oriented services in the field of ‘small surgery’.

    Purpose: To report on the use of an internal system for incident reporting. Patients and Methods: From October 2001 until June 2009, data on incidents were collected in the radiotherapy department (RT) by means of an incident reporting worksheet. The risk analysis was based on the US Navy method of mishap cause investigation, the Human Factors Analysis and Classification System (HFACS). Results: 37 incidents over 5,635 treatments were collected. Of the incidents, 20 involved deviation of the dose to the patient; only 6 showed clinical evidence of overdosage, while 2 of them showed permanent evidence of overdosage. There were 24 incidents that were classified as near misses (NM). Incorrect data input and use of an incorrect treatment field were the most common causes of the registered incidents. Reactive risk analysis showed how skill-based errors were associated with attention failure at the unsafe act level. Dose prescription and dose calculation are the most critical phases of the entire process. Most of the errors were discovered in set-up/treatment and during treatment visit/follow-up phases. The highest number of correction procedures was necessary in the phases of dose prescription and dose calculation. Conclusion: Collecting and analyzing internal incidents improves the operative procedures used in the department. (orig.)

  10. US Department of Energy DOE Nevada Operations Office, Nevada Test Site: Underground safety and health standards

    Energy Technology Data Exchange (ETDEWEB)

    1993-05-01

    The Nevada Test Site Underground Safety and Health Standards Working Group was formed at the direction of John D. Stewart, Director, Nevada Test Site Office in April, 1990. The objective of the Working Group was to compile a safety and health standard from the California Tunnel Safety Orders and OSHA for the underground operations at the NTS, (excluding Yucca Mountain). These standards are called the NTS U/G Safety and Health Standards. The Working Group submits these standards as a RECOMMENDATION to the Director, NTSO. Although the Working Group considers these standards to be the most integrated and comprehensive standards that could be developed for NTS Underground Operations, the intent is not to supersede or replace any relevant DOE orders. Rather the intent is to collate the multiple safety and health references contained in DOE Order 5480.4 that have applicability to NTS Underground Operations into a single safety and heath standard to be used in the underground operations at the NTS. Each portion of the standard was included only after careful consideration by the Working Group and is judged to be both effective and appropriate. The specific methods and rationale used by the Working Group are outlined as follows: The letter from DOE/HQ, dated September 28, 1990 cited OSHA and the CTSO as the safety and health codes applicable to underground operations at the NTS. These mandated codes were each originally developed to be comprehensive, i.e., all underground operations of a particular type (e.g., tunnels in the case of the CTSO) were intended to be adequately regulated by the appropriate code. However, this is not true; the Working Group found extensive and confusing overlap in the codes in numerous areas. Other subjects and activities were addressed by the various codes in cursory fashion or not at all.

    This report will give an explanation of the internal reorganization that has been done because of the necessity to optimize operation in the cooling and ventilation group. The basic structure for the group was defined at the end of 1998. We understood then that change was needed to accommodate the increased workload due to the LHC project. In addition, we face a relatively large turnover of personnel (retirements and some recruitment) with related integration issues to consider. We would also like to implement new approaches in the management of both operations and maintenance. After some running-in problems during the first half of 1999, we realized that much more could be gained with the analysis and the definition and documenting of each single function and generic activity within the group. The authors will explain how this analysis was carried out and give some feedback of the outcome, so far.

    2016-01-01

    This book provides the mathematical foundations for Feynman's operator calculus and for the Feynman path integral formulation of quantum mechanics as a natural extension of analysis and functional analysis to the infinite-dimensional setting. In one application, the results are used to prove the last two remaining conjectures of Freeman Dyson for quantum electrodynamics. In another application, the results are used to unify methods and weaken domain requirements for non-autonomous evolution equations. Other applications include a general theory of Lebesgue measure on Banach spaces with a Schauder basis and a new approach to the structure theory of operators on uniformly convex Banach spaces. This book is intended for advanced graduate students and researchers.

    2015-01-01

    Full Text Available The world is changing at a fast pace in a number of different areas, economically, politically technologically and socially. All these facts have strong impact on how managers organize their work. Traditionally they focus on delivering efficiency through large bureaucracies which are hierarchical in nature, very much around process and stability. What this mitigates against perhaps it is innovation and flexibility. A demand is no longer predictable and service has to be equally flexible for demand that exists nowadays. The emergence of post bureaucratic organizations is about being leaner, flatter and being much more network-based. Within that network employees are being empowered to take responsibility for producing innovations themselves. In order to speed up the process it is critical to systematize the process of managing people in the back office. Human Resource Management strategies are being transformed by internal social networks and social human resource technologies to better collaborative, transition into social enterprises, and change the positioning of human resource departments from back office to front office activities. All of these subjects are applied and the case study of hotel Zira human resource department is explained and showed in detail with the specific questionnaire. One of the main challenges that human resource management is also facing is the talent management and the number one responsibility of leadership is how to manage talent, how to attract it, utilize and eventually retain it.

    Full Text Available Purpose: Trauma is one of the most common reason of admissions to emergency departments. In this study, it was aimed to determine the demographic characteristics, etiology, morbidity and mortality rates and prognosis of adult trauma patients admitted to our emergency department (ED. Materials and Methods: Patients over the age of 18 years, who admitted to ED between 01 March 2011 and 31 August 2011 were included in this retrospective study. Patient examination cards, hospitalization files and records entered with ICD 10 codes to hospital automation system were analyzed. Patients with inaccessible data were excluded from the study. Results: During the study period, total number of 110495 patients admitted to ED, and 13585 (12,29% of them admitted with trauma. Simple extremity injuries (38,28% and falls (31,7% were most common etiological factors. Glasgow coma scales of 99,71% of the patients were between 13 and 15. Of the patients with trauma, 9,6% had a Computed Tomography (CT scan, and 84,5% of CT scans were evaluated as normal, and cranial CT was the most requested one. Only 6% of the patients were hospitalized, and 0,9% of the trauma patients died. Falls from height in females and traffic accidents in males were the leading causes of death. Conclusion: Most of the patients with simple traumas admitted to ED can be discharged from the hospital with a complete history and careful examination. The rate of unnecessary medical tests, loss of time and waste money should be reduced, and the time and labor allocated to severe patients can be increased by this way.

    2012-01-01

    The launch environment is a challenging regime to work due to changing system dynamics, changing environmental loading, joint compression loads that cannot be easily applied on the ground, and control effects. Operational testing is one of the few feasible approaches to capture system level dynamics since ground testing cannot reproduce all of these conditions easily. However, the most successful applications of Operational Modal Testing involve systems with good stationarity and long data acquisition times. This paper covers an ongoing effort to understand the launch environment and the utility of current operational modal tools. This work is expected to produce a collection of operational tools that can be applied to non-stationary launch environment, experience dealing with launch data, and an expanding database of flight parameters such as damping. This paper reports on recent efforts to build a software framework for the data processing utilizing existing and specialty tools; understand the limits of current tools; assess a wider variety of current tools; and expand the experience with additional datasets as well as to begin to address issues raised in earlier launch analysis studies.

  2. Analysis of Operational Risks in Shipbuilding Industry

    Daniela MATEI

    2012-11-01

    Full Text Available Our paper emphasizes the opportunities provided both for the academic research and companies by using a proposed model of analyzing the operational risks within business in general and shipbuilding industry in particular. The model aims to display the loss distribution from the operational risk for each business line/ type of event, based on frequency and severity estimation of the events. These estimations are derived mainly from the history logs of internal loss events. The calculations extend over a certain period of time in the future with a certain level of confidence. It should also be mentioned that the proposed model estimates unexpected losses, without making any suppositions concerning the values of the expected and unexpected losses. Several ideas could be extracted by analyzing and synthesizing the theoretical models from available literature. These ideas were analyzed in order to develop a model for operational risk analysis that is adapted to shipbuilding. This paper describes a new model, which can be applied to the naval industry to quantify operational risks.

    Simulation in multiple contexts over the course of a 10-week period served as a core learning strategy to orient experienced clinicians before opening a large new urban freestanding emergency department. To ensure technical and procedural skills of all team members, who would provide care without on-site recourse to specialty backup, we designed a comprehensive interprofessional curriculum to verify and regularize a wide range of competencies and best practices for all clinicians. Formulated under the rubric of systems integration, simulation activities aimed to instill a shared culture of patient safety among the entire cohort of 43 experienced emergency physicians, physician assistants, nurses, and patient technicians, most newly hired to the health system, who had never before worked together. Methods throughout the preoperational term included predominantly hands-on skills review, high-fidelity simulation, and simulation with standardized patients. We also used simulation during instruction in disaster preparedness, sexual assault forensics, and community outreach. Our program culminated with 2 days of in-situ simulation deployed in simultaneous and overlapping timeframes to challenge system response capabilities, resilience, and flexibility; this work revealed latent safety threats, lapses in communication, issues of intake procedure and patient flow, and the persistence of inapt or inapplicable mental models in responding to clinical emergencies.

    1993-09-01

    This report contains the environmental monitoring and assessment results for the Nevada Test Site for 1992. Monitoring and surveillance on and around the NTS by DOE contractors and Site user organizations during 1992 indicated that underground nuclear testing operations were conducted in compliance with regulations, i.e., the dose the maximally exposed offsite individual could have received was less than 0.15 percent of the guideline for air exposure. All 1992 nuclear events took place during the first three quarters of the calendar year prior to the Congressional testing moratorium. All discharges of radioactive liquids remained onsite in containment ponds, and there was no indication of potential migration of radioactivity to the offsite area through groundwater. Surveillance around the NTS indicated that airborne radioactivity from test operations was not detectable offsite, and no measurable net exposure to members of the offsite population was detected through the offsite dosimetry program. Using the CAP88-PC model and NTS radionuclide emissions data, the calculated maximum effective dose equivalent offsite would have been 0.012 mrem. Any person receiving this dose was also exposed to 78 mrem from natural background radiation. There were no nonradiological releases to the offsite area. Hazardous wastes were shipped to EPA-approved disposal facilities. Compliance with the various regulations stemming from the National Environmental Policy Act is being achieved and, where mandated, permits for air and water discharges and waste management have been obtained from the appropriate agencies. Non-NTS support facilities complied with the requirements of air quality permits and state or local wastewater discharge and hazardous waste permits.

    Traditional department stores are now faced up with challenges brought by the economic depression and explosive growth of e-retailing.Whether the joint-operation,as a mainstream,should be replaced by the self-op-eration is a dilemma for department stores.Depending on the definition of the self-operation mode,this paper propo-ses three restrictive factors:high format elasticity,high brand elasticity and China's unbalanced market.Therefore, department stores should cultivate their own brands to get rid of self-operation constrains.%近年来电子零售业的爆发式增长使传统百货店面临严峻挑战。针对目前百货店主要实行的联营制是否应被自营制取代,理论界与实践界观点不一。基于对百货店自营制范畴的界定,发现“较高的业态弹性、较高的品牌弹性和中国市场的不平衡性”是制约百货店自营制发展的三大主要因素。为了摆脱这些因素的制约,百货店回归传统的自营制,必须加快自主品牌的建设。

    NESHAPs limits the emission of radionuclides to the ambient air from DOE facilities to levels resulting in an annual effective dose equivalent (EDE) of 10 mrem (100 {micro}Sv) to any member of the public. The EDEs for the Lawrence Livermore National Laboratory (LLNL) site-wide maximally exposed members of the public from operations in 2006 are summarized here. Livermore site: 0.0045 mrem (0.045 {micro}Sv) (36% from point source emissions, 64% from diffuse source emissions). The point source emissions include gaseous tritium modeled as tritiated water vapor as directed by the U.S. Environmental Protection Agency (EPA) Region IX; the resulting dose is used for compliance purposes. Site 300: 0.016 mrem (0.16 {micro}Sv) (87.5% from point source emissions, 12.5% from diffuse source emissions). The EDEs were calculated using the EPA-approved CAP88-PC air dispersion/dose-assessment model, except for doses for two diffuse sources that were estimated using measured radionuclide concentrations and dose coefficients. Specific inputs to CAP88-PC for the modeled sources included site-specific meteorological data and source emissions data, the latter variously based on continuous stack effluent monitoring data, stack flow or other release-rate information, ambient air monitoring data, and facility knowledge.

    Monitoring and surveillance on and around the Nevada Test Site (NTS) by DOE contractors and NTS user organizations during 1993 indicated that operations on the NTS were conducted in compliance with applicable federal and DOE guidelines, i.e., the dose the maximally exposed offsite individual could have received was less than 0.04 percent of the 10 mrem per year guide for air exposure. No nuclear tests were conducted due to the moratorium. All discharges of radioactive liquids remained onsite in containment ponds, and there was no indication of potential migration of radioactivity to the offsite area through groundwater. Surveillance around the NTS indicated that airborne radioactivity from diffusion, evaporation of effluents, or resuspension was not detectable offsite, and no measurable net exposure to members of the offsite population was detected through the offsite dosimetry program. Using the CAP88-PC model and NTS radionuclide emissions data, the calculated effective dose equivalent to the maximally exposed individual offsite would have been 0.004 mrem. Any person receiving this dose would also have received 97 mrem from natural background radiation. There were no nonradiological releases to the offsite area. Hazardous wastes were shipped offsite to approved disposal facilities. Compliance with the various regulations stemming from the National Environmental Policy Act is being achieved and, where mandated, permits for air and water discharges and waste management have been obtained from the appropriate agencies. Support facilities at off-NTS locations compiled with the requirements of air quality permits and state or local wastewater discharge and hazardous waste permits.

    1980-01-01

    An analysis of the major plasma processes involved in the SERT 2 spacecraft experiments was conducted to aid in the interpretation of recent data. A plume penetration model was developed for neutralization electron conduction to the ion beam and showed qualitative agreement with flight data. In the SERT 2 configuration conduction of neutralization electrons between thrusters was experimentally demonstrated in space. The analysis of this configuration suggests that the relative orientation of the two magnetic fields was an important factor in the observed results. Specifically, the opposed field orientation appeared to provide a high conductivity channel between thrusters and a barrier to the ambient low energy electrons in space. The SERT 2 neutralizer currents with negative neutralizer biases were up to about twice the theoretical prediction for electron collection by the ground screen. An explanation for the higher experimental values was a possible conductive path from the neutralizer plume to a nearby part of the ground screen. Plasma probe measurements of SERT 2 gave the clearest indication of plasma electron temperature, with normal operation being near 5 eV and discharge only operation near 2 eV.

    The US Department of Energy (DOE) Order 5400.1, ``General Environmental Protection Program,`` establishes environmental protection program requirements, authorities, and responsibilities for DOE operations. These mandates require compliance with applicable federal, state, and local environmental protection regulations. During calendar year (CY) 1995 environmental protection and monitoring programs were conducted at the Nevada Test Site (NTS) and other DOE Nevada Operations Office (DOE/NV) managed sites in Nevada and across the United States. A detailed discussion of these environmental protection and monitoring programs, and summary data and assessments for environmental monitoring results at these sites in CY 1995 are provided in the DOE/NV, Annual Site Environmental Report--1995, (ASER) DOE/NV/11718-037. A brief description of the scope of this environmental monitoring is provided below, categorized by ``on-NTS`` and ``off-NTS`` monitoring.

    The implementation of diagnosis-related groups (DRGs) sharply increased economic pressure on hospitals. Hence, process optimization was focussed on cost-intensive areas, namely the operation room (OR) departments. Work-flow in the OR is characterized by a mandatory interlocking of the job functions of many different occupational groups and the availability of a variety of different materials. Alternatives for staff assignment optimization have been published in numerous publications dealing with the importance of OR management. In this connection the issue of material logistics in the context of OR management has not been frequently addressed. In order to perform a surgical procedure according to plan, one depends on personnel and on timely availability of the materials needed. Supply of sterilized materials is of utmost importance, because in most hospitals sterilized surgical devices constitute a critical resource. In order to coordinate the OR process with the production flow of sterilized materials, an organizational connection to the OR management makes sense. Hence, in a German university hospital the Department of Hospital Sterile Supplies was integrated into the OR management of the Department of Anesthesiology. This led to a close coordination of work-flow processes, and concomitantly a significant reduction of production costs of sterile supplies could be achieved by direct interaction with the OR. Thus, hospital sterile supplies can reasonably be integrated into an OR management representing a new interesting business area for OR organization.

  20. Operational modal analysis by updating autoregressive model

    2011-04-01

    This paper presents improvements of a multivariable autoregressive (AR) model for applications in operational modal analysis considering simultaneously the temporal response data of multi-channel measurements. The parameters are estimated by using the least squares method via the implementation of the QR factorization. A new noise rate-based factor called the Noise rate Order Factor (NOF) is introduced for use in the effective selection of model order and noise rate estimation. For the selection of structural modes, an orderwise criterion called the Order Modal Assurance Criterion (OMAC) is used, based on the correlation of mode shapes computed from two successive orders. Specifically, the algorithm is updated with respect to model order from a small value to produce a cost-effective computation. Furthermore, the confidence intervals of each natural frequency, damping ratio and mode shapes are also computed and evaluated with respect to model order and noise rate. This method is thus very effective for identifying the modal parameters in case of ambient vibrations dealing with modern output-only modal analysis. Simulations and discussions on a steel plate structure are presented, and the experimental results show good agreement with the finite element analysis.

    Full Text Available This paper gives an overview of the main components of operational modal analysis (OMA and can serve as a tutorial for research oriented OMA applications. The paper gives a short introduction to the modeling of random responses and to the transforms often used in OMA such as the Fourier series, the Fourier integral, the Laplace transform, and the Z-transform. Then the paper introduces the spectral density matrix of the random responses and presents the theoretical solutions for correlation function and spectral density matrix under white noise loading. Some important guidelines for testing are mentioned and the most common techniques for signal processing of the operating signals are presented. The algorithms of some of the commonly used time domain and frequency domain identification techniques are presented and finally some issues are discussed such as mode shape scaling, and mode shape expansion. The different techniques are illustrated on the difficult case of identifying the three first closely spaced modes of the Heritage Court Tower building.

    This report presents Preliminary Remediation Goals (PRGs) for use in human health risk assessment efforts under the United States Department of Energy, Oak Ridge Operations Office Environmental Restoration (ER) Division. Chemical-specific PRGs are concentration goals for individual chemicals for specific medium and land use combinations. The PRGs are referred to as risk-based because they have been calculated using risk assessment procedures. Risk-based calculations set concentration limits using both carcinogenic or noncarcinogenic toxicity values under specific exposure pathways. The PRG is a concentration that is derived from a specified excess cancer risk level or hazard quotient. This report provides the ER Division with standardized PRGs which are integral to the Remedial Investigation/Feasibility Study process. By managing the assumptions and systems used in PRG derivation, the Environmental Restoration Risk Assessment Program will be able to control the level of quality assurance associated with these risk-based guideline values.

This document provides the ER Division with standardized PRGs which are integral to the Remedial Investigation/Feasibility Study process. They are used during project scooping (Data Quality Objectives development), in screening level risk assessments to support early action or No Further Investigation decisions, and in the baselines risk assessment where they are employed in the selection of chemicals of potential concern. The primary objective of this document is to standardize these values and eliminate any duplication of effort by providing PRGs to all contractors involved in risk activities. In addition, by managing the assumptions and systems used in PRG derivation, the ER Risk Assessment Program will be able to control the level of quality assurance associated with these risk-based guideline values.

    The US Department of Energy (DOE) has prepared a sitewide environmental assessment (EA) of the proposed action to continue and expand present-day activities on the DOE Grand Junction Projects Office (GJPO) facility in Grand Junction, Colorado. Because DOE-GJPO regularly proposes and conducts many different on-site activities, DOE decided to evaluate these activities in one sitewide EA rather than in multiple, activity-specific documents. On the basis of the information and analyses presented in the EA, DOE has determined that the proposed action does not constitute a major Federal action significantly affecting the quality of the human environment, as defined by the National Environmental Policy Act (NEPA) of 1969. Therefore, preparation of an environmental impact statement is not required for facility operations, and DOE is issuing this Finding of No Significant Impact (FONSI).

    Solid Waste Management (SWM) commissioned this Special Analysis (SA) to determine the effects of placing operational stormwater runoff covers (referred to as covers in the remainder of this document) over slit trench (ST) disposal units ST1 through ST7 (the center set of slit trenches). Previously the United States Department of Energy (DOE) entered into an agreement with the United States Environmental Protection Agency (EPA) and the South Carolina Department of Health and Environmental Control (SCDHEC) to place covers over Slit Trenches 1 and 2 to be able to continue disposing Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) solid waste (see USDOE 2008). Because the covers changed the operating conditions, DOE Order 435.1 (DOE 1999) required that an SA be performed to assess the impact. This Special Analysis has been prepared to determine the effects of placing covers over slit trenches at about years 5, 10 and 15 of the 30-year operational period. Because some slit trenches have already been operational for about 15 years, results from analyzing covers at 5 years and 10 years provide trend analysis information only. This SA also examined alternatives of covering Slit Trenches 1 and 2 with one cover and Slit Trenches 3 and 4 with a second cover versus covering them all with a single cover. Based on modeling results, minimal differences exist between covering Slit Trench groups 1-2 and 3-4 with two covers or one large cover. This SA demonstrates that placement of covers over slit trenches will slow the subsequent release and transport of radionuclides in the vadose zone in the early time periods (from time of placement until about 100 years). Release and transport of some radionuclides in the vadose zone beyond 100 years were somewhat higher than for the case without covers. The sums-of-fractions (SOFs) were examined for the current waste inventory in ST1 and ST2 and for estimated inventories at closure for ST3 through ST7. In all

    On February 24, 1992, the Occupational Safety and Health Administration (OSHA) released a revised version of Section 29 Code of Federal Regulations CFR Part 1910 that added Section 1910.119, entitled ``Process Safety Management of Highly Hazardous Chemicals`` (the PSM Rule). Because US Department of Energy (DOE) Orders 5480.4 and 5483.1A prescribe OSHA 29 CFR 1910 as a standard in DOE, the PSM Rule is mandatory in the DOE complex. A major element in the PSM Rule is the process hazard analysis (PrHA), which is required for all chemical processes covered by the PSM Rule. The PrHA element of the PSM Rule requires the selection and application of appropriate hazard analysis methods to systematically identify hazards and potential accident scenarios associated with processes involving highly hazardous chemicals (HHCs). The analysis in this report is an example PrHA performed to meet the requirements of the PSM Rule. The PrHA method used in this example is the hazard and operability (HAZOP) study, and the process studied is the new Hanford 300-Area Water Treatment Facility chlorination process, which is currently in the design stage. The HAZOP study was conducted on May 18--21, 1993, by a team from the Westinghouse Hanford Company (WHC), Battelle-Columbus, the DOE, and Pacific Northwest Laboratory (PNL). The chlorination process was chosen as the example process because it is common to many DOE sites, and because quantities of chlorine at those sites generally exceed the OSHA threshold quantities (TQs).

    1991-01-01

    Except in low-bandwidth systems, knowledge of the human operator transfer function is essential for high-performance telerobotic systems. This information has usually been derived from detailed analyses of tracking performance, in which the human operator is considered as a complete system rather than as a summation of a number of subsystems, each of which influences the operator's output. Studies of one of these subsystems, the limb mechanics system, demonstrate that large parameter variations can occur that can have a profound effect on the stability of force-reflecting telerobot systems. An objective of this research was to decompose the performance of the human operator system in order to establish how the dynamics of each of the elements influence the operator's responses.

    Business intelligence is becoming an important strategic tool for business management. Companies have invested significant resources in applications for customer relationship management (CRM), supply chain management (SCM), enterprise resource planning (ERP), e-commerce, among others, which collect vast amounts of data. Today, these same companies are realizing that no matter how robust their application feature sets are, without an equally robust BI mechanism to make use of the collected data, these applications are ultimately coming up short. They do not provide actionable information to end users nor can they give a global understanding among all the organization's information from the various databases for accounting, CRM, and so on.

    The DIII-D tokamak research program is carried out by General Atomics for the U.S. Department of Energy. The DIII-D is the most flexible and best diagnosed tokamak in the world and the second largest tokamak in the U.S. The primary goal of the DIII-D tokamak research program is to provide data needed by ITER and to develop a conceptual physics blueprint for a commercially attractive electrical demonstration plant (DEMO) that would open a path to fusion power commercialization. Specific DIII-D objectives include the steady-state sustainment of plasma current as well as demonstrating techniques for microwave heating, divertor heat removal, fuel exhaust and tokamak plasma control. The DIII-D program is addressing these objectives in an integrated fashion with high beta and with good confinement. The DIII-D long-range plan is organized into two major thrusts; the development of advanced divertor and the development of advanced tokamak concepts. These two thrusts have a common goal: an improved DEMO reactor with lower cost and smaller size than the present DEMO which can be extrapolated from the conventional ITER operational scenario. In order to prepare for the long-range program, in FY92 the DIII-D research program concentrated in three major areas: Tokamak Physics, Divertor and Boundary Physics, and Advanced Tokamak Studies.

    The US Department of Energy (DOE) is now engaged in a program of environmental restoration nationwide across its 45 sites. It is also bringing its facilities into compliance with environmental regulations, decontaminating and decommissioning unwanted facilities, and constructing new waste management facilities. One of the most difficult questions that DOE must face in successfully remediating its inactive waste sites, decontaminating and decommissioning its inactive facilities, and operating its waste management facilities is: ``What criteria and standards should be met?`` Acceptable standards or procedures for determining standards will assist DOE in its conduct of ongoing waste management and pending cleanup activities by helping to ensure that those activities are conducted in compliance with applicable laws and regulations and are accepted by the regulatory community and the public. This document reports on the second of three baseline activities that are being conducted as prerequisites to either the development of quantitative standards that could be used by DOE, or consistent procedures for developing such standards. The first and third baseline activities are also briefly discussed in conjunction with the second of the three activities.

    Epileptic seizures account for 1%-2% of all admissions of patients to the emergency department (ED). The present study aimed to determine whether venous blood pH, bicarbonate, base excess, and lactate levels taken within 1 hour of the last seizure episode help to determine seizure recurrence in emergency departments. A cross-sectional study was conducted in the emergency department (ED) between January and July, 2012. Patients who were admitted to the emergency department consecutively were included in the study if they were 14 years or older and within 1 hour after last seizure. Demographics, seizure type, use of antiepileptic drugs, observation period at the emergency department, seizure recurrence, pH, bicarbonate, base excess, and lactate levels from venous blood gas analysis were determined. A total of 94 patients aged 14 years or older were included in the study. Of these patients, 10.6% (n=10) experienced recurrent seizures in the observation period at the emergency department. To predict recurrent seizures in ED, threshold venous blood gas values were determined as follows: pH7.65 mmol/L [sensitivity 80% (95%CI: 44-96), negative predictive value 96.6% (95%CI: 87-99)]. If venous blood gas analysis is made on pH, base excess, lactate and bicarbonate immediately one hour after the last epileptic seizure episode, it is possible to predict whether the patient will have seizure recurrence.

    Full Text Available Background: Prescription pattern analysis is an essential tool to provide an insight regarding the existing drug usage and to ensure rational drug therapy. Even though drugs used for gynecological disorders are one of the commonly used, they are least studied in terms of prescribing patterns. Hence the present study was planned to analyze the prescribing pattern and WHO core prescribing indicators among post-operative patients of Gynaecology department in our institute. Methods: A prospective observational study was conducted in 76 post-operative patients of Gynaecology department for a period of six months. Each prescription was analyzed for demographic data, total number and various categories of drugs prescribed, the percentage of individual drugs prescribed in each category, the dosage forms and the percentage of drugs prescribed by generic name, and from essential drug list were also analyzed. Results: A total of 990 medications were prescribed among which anti-microbial agents (32.52% were the most commonly prescribed category followed by analgesics (19.60% and Intravenous fluids (13.53%. Metronidazole (27.02% was the most commonly prescribed antimicrobial, Diclofenac (68.04% was the commonly prescribed analgesics and Ringer lactate (38.81% was the commonly prescribed Intravenous fluid. Most commonly prescribed antiulcer drug was ranitidine (75.0%, antiemetic was Ondansetron (76.39%. Majority of drugs (72.54% were prescribed by generic name. Average number of drugs per prescription was 13.03. Percentages of encounters with antibiotics were 32.52%. The percentage of drugs prescribed from the National List of Essential Medicines (NLEM was 82.16%. Injection (57.78% was the most common drug formulation. Conclusions: Antimicrobial agents and analgesics were the most commonly prescribed drugs. Prescription by generic name was high, usage of antibiotics and injections were also high and Poly-pharmacy was common, especially among antimicrobial

    Full Text Available Introduction: An efficient university should have a real goal and could produce the most output with the least use of inputs. Evaluation systems are an inseparable part of each organization and university. By efficiency calculation, useful information will be created about strengths, weaknesses, opportunities, threats, and opportunities for improvement. Data envelopment analysis is a useful technique for evaluation of efficiency. This technique needs all the inputs and outputs to be measured precisely.Methods and material: The present study is a descriptive, analytical, cross-sectional, and retrospective research which measures the research efficiency of educational departments of Shiraz faculty of medicine by using DEA technique from 2006 to 2011. Extracted data were analyzed by Microsoft excel and DEA master software.Finding: Department of pediatric and psychiatrics were efficient from 2006 to 2011. Other departments have some inefficiency. Neurosurgery department has least average of efficiency. The average of technical efficiency for all departments was 73.873.Conclusion: where the difference between efficiency score of the department and 100 is more, the department’s needs to improve its outputs will be more. Those groups which are more inefficient waste the resources more. This method also could help the faculty of medicine to identify their weakness and try for improvement

  4. OPERATIONAL MODAL ANALYSIS SCHEMES USING CORRELATION TECHNIQUE

    2005-01-01

    For some large-scale engineering structures in operating conditions, modal parameters estimation must base itself on response-only data. This problem has received a considerable amount of attention in the past few years. It is well known that the cross-correlation function between the measured responses is a sum of complex exponential functions of the same form as the impulse response function of the original system. So this paper presents a time-domain operating modal identification global scheme and a frequency-domain scheme from output-only by coupling the cross-correlation function with conventional modal parameter estimation. The outlined techniques are applied to an airplane model to estimate modal parameters from response-only data.

    Hörmander , Lars

    2005-01-01

    This volume is an expanded version of Chapters III, IV, V and VII of my 1963 book "Linear partial differential operators". In addition there is an entirely new chapter on convolution equations, one on scattering theory, and one on methods from the theory of analytic functions of several complex variables. The latter is somewhat limited in scope though since it seems superfluous to duplicate the monographs by Ehrenpreis and by Palamodov on this subject. The reader is assumed to be familiar with distribution theory as presented in Volume I. Most topics discussed here have in fact been encountered in Volume I in special cases, which should provide the necessary motivation and background for a more systematic and precise exposition. The main technical tool in this volume is the Fourier- Laplace transformation. More powerful methods for the study of operators with variable coefficients will be developed in Volume III. However, constant coefficient theory has given the guidance for all that work. Although the field...

    Full Text Available Introduction. Cost of anaesthesiology represent defined measures to determine a precise profile of expenditure estimation of surgical treatment, which is important regarding planning of healthcare activities, prices and budget. Objective. In order to determine the actual value of anaestesiological services, we started with the analysis of activity based costing (ABC analysis. Methods. Retrospectively, in 2005 and 2006, we estimated the direct costs of anestesiological services (salaries, drugs, supplying materials and other: analyses and equipment. of the Institute of Anaesthesia and Resuscitation of the Clinical Centre of Serbia. The group included all anesthetized patients of both sexes and all ages. We compared direct costs with direct expenditure, “each cost object (service or unit” of the Republican Health-care Insurance. The Summary data of the Departments of Anaesthesia documented in the database of the Clinical Centre of Serbia. Numerical data were utilized and the numerical data were estimated and analyzed by computer programs Microsoft Office Excel 2003 and SPSS for Windows. We compared using the linear model of direct costs and unit costs of anaesthesiological services from the Costs List of the Republican Health-care Insurance. Results. Direct costs showed 40% of costs were spent on salaries, (32% on drugs and supplies, and 28% on other costs, such as analyses and equipment. The correlation of the direct costs of anaestesiological services showed a linear correlation with the unit costs of the Republican Healthcare Insurance. Conclusion. During surgery, costs of anaesthesia would increase by 10% the surgical treatment cost of patients. Regarding the actual costs of drugs and supplies, we do not see any possibility of costs reduction. Fixed elements of direct costs provide the possibility of rationalization of resources in anaesthesia.

    An industrial hygiene exposure database and surveillance system was developed in partnership between National Institute for Occupational Safety and Health (NIOSH)-funded independent investigators and practicing industrial hygienists at the Rocky Flats Environmental Technology Site (RFETS) in Golden, Colo. RFETS is a former U.S. Department of Energy nuclear weapons plant that is now in cleanup phase. This project is presented as a case study in the development of an exposure database and surveillance system in terms that are generalizable to most other industries and work contexts. Steps include gaining organizational support; defining system purpose and scope; defining database elements and coding; planning practical and efficient analysis strategies; incorporating reporting capabilities; and anticipating communication strategies that maximize the probability that surveillance findings will feed back to preventive applications. For each of these topics, the authors describe both general considerations as well as the specific choices made for this system. An important feature of the system is a two-tier task-coding scheme comprising 33 categories of task groups. Examples of grouped analyses of exposure data captured during the system pilot period demonstrate applications to exposure control, medical surveillance, and other preventive measures.

    2012-01-01

    The All-Terrain Hex-Limbed Extra-Terrestrial Explorer (ATHLETE) is a modular mobility and manipulation platform being developed to support NASA operations in a variety of missions, including exploration of planetary surfaces. The agile system consists of a symmetrical arrangement of six limbs, each with seven articulated degrees of freedom and a powered wheel. This design enables transport of bulky payloads over a wide range of terrain and is envisioned as a tool to mobilize habitats, power-generation equipment, and other supplies for long-range exploration and outpost construction. In 2010, ATHLETE traversed more than 80 km in field environments over eight weeks of testing, demonstrating that the concept is well suited to long-range travel. However, while ATHLETE is designed to travel at speeds of up to 5 kilometers per hour, the observed average traverse rate during field-testing rarely exceeded 1.5 kilometers per hour. This paper investigates sources of inefficiency in ATHLETE traverse operations and identifies targets for improvement of overall traverse rate.

    Building resilience into today's complex infrastructures is critical to the daily functioning of society and its ability to withstand and recover from natural disasters, epidemics, and cyber-threats. This study proposes quantitative measures that implement the definition of engineering resilience advanced by the National Academy of Sciences. The approach is applicable across physical, information, and social domains. It evaluates the critical functionality, defined as a performance function of time set by the stakeholders. Critical functionality is a source of valuable information, such as the integrated system resilience over a time interval, and its robustness. The paper demonstrates the formulation on two classes of models: 1) multi-level directed acyclic graphs, and 2) interdependent coupled networks. For both models synthetic case studies are used to explore trends. For the first class, the approach is also applied to the Linux operating system.

    1976-01-01

    The operations of hydropower systems were analyzed with emphasis on water resource management, to determine how aerospace derived information system technologies can increase energy output. Better utilization of water resources was sought through improved reservoir inflow forecasting based on use of hydrometeorologic information systems with new or improved sensors, satellite data relay systems, and use of advanced scheduling techniques for water release. Specific mechanisms for increased energy output were determined, principally the use of more timely and accurate short term (0-7 days) inflow information to reduce spillage caused by unanticipated dynamic high inflow events. The hydrometeorologic models used in predicting inflows were examined to determine the sensitivity of inflow prediction accuracy to the many variables employed in the models, and the results used to establish information system requirements. Sensor and data handling system capabilities were reviewed and compared to the requirements, and an improved information system concept outlined.

    Vehicle-to-vehicle (V2V) communications promises to increase roadway safety by providing each vehicle with 360 degree situational awareness of other vehicles in proximity, and by complementing onboard sensors such as radar or camera in detecting imminent crash scenarios. In the United States, approximately three hundred million automobiles could participate in a fully deployed V2V system if Dedicated Short-Range Communication (DSRC) device use becomes mandatory. The system s reliance on continuous communication, however, provides a potential means for unscrupulous persons to transmit false data in an attempt to cause crashes, create traffic congestion, or simply render the system useless. V2V communications must be highly scalable while retaining robust security and privacy preserving features to meet the intra-vehicle and vehicle-to-infrastructure communication requirements for a growing vehicle population. Oakridge National Research Laboratory is investigating a Vehicle-Based Security System (VBSS) to provide security and privacy for a fully deployed V2V and V2I system. In the VBSS an On-board Unit (OBU) generates short-term certificates and signs Basic Safety Messages (BSM) to preserve privacy and enhance security. This work outlines a potential VBSS structure and its operational concepts; it examines how a vehicle-based system might feasibly provide security and privacy, highlights remaining challenges, and explores potential mitigations to address those challenges. Certificate management alternatives that attempt to meet V2V security and privacy requirements have been examined previously by the research community including privacy-preserving group certificates, shared certificates, and functional encryption. Due to real-world operational constraints, adopting one of these approaches for VBSS V2V communication is difficult. Timely misbehavior detection and revocation are still open problems for any V2V system. We explore the alternative approaches that may be

    1994-10-01

    New techniques and sensors to identify the molecular, chemical, or elemental structures unique to drugs are being developed under several national programs. However, the challenge faced by U.S. drug enforcement and Customs officials goes far beyond the simple technical capability to detect an illegal drug. Entry points into the U.S. include ports, border crossings, and airports where cargo ships, vehicles, and aircraft move huge volumes of freight. Current technology and personnel are able to physically inspect only a small fraction of the entering cargo containers. The complexities of how to best utilize new technology to aid the detection process and yet not adversely affect the processing of vehicles and time-sensitive cargo is the challenge faced by these officials. This paper describes an ARPA sponsored initiative to develop a simple, yet useful, method for examining the operational consequences of utilizing various procedures and technologies in combination to achieve an `acceptable' level of detection probability. Since Customs entry points into the U.S. vary from huge seaports to a one lane highway checkpoint between the U.S. and Canadian or Mexico border, no one system can possibly be right for all points. This approach can examine alternative concepts for using different techniques/systems for different types of entry points. Operational measures reported include the average time to process vehicles and containers, the average and maximum numbers in the system at any time, and the utilization of inspection teams. The method is implemented via a PC-based simulation written in GPSS-PC language. Input to the simulation model is (1) the individual detection probabilities and false positive rates for each detection technology or procedure, (2) the inspection time for each procedure, (3) the system configuration, and (4) the physical distance between inspection stations. The model offers on- line graphics to examine effects as the model runs.

The detector consists of an array of 300 water tanks, each containing 200 ktons of purified water and instrumented with 4 PMTs. Located at an elevation of 4100m a.s.l. near the Sierra Negra volcano in central Mexico, HAWC has a threshold for gamma-ray detection well below 1 TeV and a sensitivity to TeV-scale gamma-ray sources an order of magnitude better than previous air-shower arrays. The detector operates 24 hours/day and observes the overhead sky (2 sr), making it an ideal survey instrument. We describe the configuration of HAWC with an emphasis on how the design was optimized, describe the data acquired, reconstructed and an- alyzed. Finally, we will demonstrate the sensitivity of the detector using the observation of the Crab. This paper serves as a detailed technical description of the foundations of the numerous analyses presented at this meeting by members of the HAWC collaboration.

The nonlinear relationship between network parameters and resilience levels confirms the utility of the proposed approach, which is of benefit to analysts and designers of complex systems and networks.

    1980-07-01

    Open cycle magnetohydrodynamic (OCMHD) conceptual power plant designs are studied in the context of a utility system to form a better basis for understanding their design, design requirements, and market possibilities. Based on assumed or projected plant costs and performance characteristics, assumed economics and escalation factors, and one coal supply and delivery scenario, overall and regional OCMHD utility market possibilities are reviewed. Additionally, for one hypothetical utility system a generation expansion plan is developed that includes OCMHD as a baseload power generating station. The impact on generation system economics and operation of alternating selected MHD plant cost and performance characteristics is reviewed. Baseload plant availability is shown as an important plant design consideration, and a general methodology and data base is developed to assess the impact on design and cost of various reliability decisions. An overall plant availability goal is set and the required availabilities of various MHD high technology components are derived to meet the plant goal. The approach is then extended to projecting channel life goals for various plant design configurations and assumptions.

A programming and reporting tool was developed throught a database. The collected data (from January to December 2013) related to the reported physiotherapists activities were analysed and matched to operating theater's activities in order to find the correlation value. The results are lined up the hypothesis stated in the planning phase of the organizational model's project (in absence of hystorical referral). Correlation between Physiotherapists and Operation Theather's activities was good (r=0.59), giving us a reliable predictional model. This study has some limitations mostly related to the resistence expressed by employees in the change management.

    The first atmospheric event built only from infrasound arrivals was reported in the Reviewed Event Bulletin (REB) of the International Data Centre (IDC) of the Comprehensive Nuclear Test Ban Treaty Organization (CTBTO) in 2003. In the last decade, 42 infrasound stations from the International Monitoring System (IMS) have been installed and are transmitting data to the IDC. The growing amount of infrasound data and detections produced by the automatic system challenged the station and network processing at the IDC, which required the Organization to redesign the way infrasound data are processed. Each infrasound array is processed separately for signal detection using a progressive multi-channel correlation method (DFX-PMCC). For each detection, signal features - onset time, amplitude, frequency, duration, azimuth, phase velocity, F-statistics - are measured and used to identify a detection as infrasonic, seismic, or noise (including clutter). Infrasonic signals along with seismic and hydroacoustic signals are subsequently associated with Global Association software (GA) between stations to locate events. During detection and association phases, criteria are applied to eliminate clutter, identify signals of interest, and keep the number of automatic events containing infrasound detections to a manageable level for analyst review. The IDC has developed analysis and visualization tools specifically for infrasound review (e.g. Geotool-PMCC). The IDC has continued to build the Infrasound Reference Event Database (IRED) from observations on the IMS network. This database assists both the routine IDC infrasound analysis and analyst training as it reflects the global detection capability of the network, illustrates the spatial and temporal variability of the observed phenomena, and demonstrates the various origins of infragenic sources. Since 2007, the IDC has introduced new analyst procedures to review and add selected infrasound events to the REB. In early 2010, the IDC

    This plan incorporates U.S. Department of Energy (DOE) Office of Legacy Management (LM) standard operating procedures (SOPs) into environmental monitoring activities and will be implemented at all sites managed by LM. This document provides detailed procedures for the field sampling teams so that samples are collected in a consistent and technically defensible manner. Site-specific plans (e.g., long-term surveillance and maintenance plans, environmental monitoring plans) document background information and establish the basis for sampling and monitoring activities. Information will be included in site-specific tabbed sections to this plan, which identify sample locations, sample frequencies, types of samples, field measurements, and associated analytes for each site. Additionally, within each tabbed section, program directives will be included, when developed, to establish additional site-specific requirements to modify or clarify requirements in this plan as they apply to the corresponding site. A flowchart detailing project tasks required to accomplish routine sampling is displayed in Figure 1. LM environmental procedures are contained in the Environmental Procedures Catalog (LMS/PRO/S04325), which incorporates American Society for Testing and Materials (ASTM), DOE, and U.S. Environmental Protection Agency (EPA) guidance. Specific procedures used for groundwater and surface water monitoring are included in Appendix A. If other environmental media are monitored, SOPs used for air, soil/sediment, and biota monitoring can be found in the site-specific tabbed sections in Appendix D or in site-specific documents. The procedures in the Environmental Procedures Catalog are intended as general guidance and require additional detail from planning documents in order to be complete; the following sections fulfill that function and specify additional procedural requirements to form SOPs. Routine revision of this Sampling and Analysis Plan will be conducted annually at the

    2015-11-17

    Present trends in hospital management are facilitating the utilization of more accurate costing methods, which potentially results in superior cost-related information and improved managerial decision-making. However, the Activity-Based Costing method (ABC), which was designed for cost allocation purposes in the 1980s, is not widely used by healthcare organizations. This study analyzes costs related to selected categories of patients, those suffering from psoriasis, varicose ulcers, eczema and other conditions, within a dermatology department at a Czech regional hospital. The study was conducted in a hospital department where both inpatient and outpatient care are offered. Firstly, the diseases treated at the department were identified. Further costs were determined for each activity using ABC. The study utilized data from managerial and financial accounting, as well as data obtained through interviews with departmental staff. Using a defined cost-allocation procedure makes it possible to determine the cost of an individual patient with a given disease more accurately than via traditional costing procedures. The cost analysis focused on the differences between the costs related to individual patients within the selected diagnoses, variations between inpatient and outpatient treatments and the costs of activities performed by the dermatology department. Furthermore, comparing the costs identified through this approach and the revenue stemming from the health insurance system is an option. Activity-Based Costing is more accurate and relevant than the traditional costing method. The outputs of ABC provide an abundance of additional information for managers. The benefits of this research lie in its practically-tested outputs, resulting from calculating the costs of hospitalization, which could prove invaluable to persons involved in hospital management and decision-making. The study also defines the managerial implications of the performed cost analysis for the

    Full Text Available Introduction: Successful performance of emergency department(ED is one of the important indications of increasing the satisfaction among referees. The insurance of such successful performance is fiscal discipline and avoiding from non-beneficial activities in this department. Therefore, the increasing revenue of emergency department is one of the interested goals of hospital management system. According to above-mentioned, the researchers assessed problems lead to loss the revenue of ED and eliminate them by using failure mode and effects analysis (FMEA.Methods: This was the prospective cohort study performed during 18 months, set in 6 phases. In the first phase, the failures were determined and some solutions suggested to eliminate them. During 2-5 phases, based on the prioritizing the problems, solutions were performed. In the sixth phase, final assessment of the study was done. Finally, the feedback of system’s revenue was evaluated and data analyzed using repeated measure ANOVA.Results: Lack of recording the consuming instrument and attribution of separate codes for emergency services of hospitalized patients were the most important failures that lead to decrease the revenue of ED. Such elimination caused to 75.9% increase in revenue within a month (df = 1.6; F = 84.0; p<0.0001.  Totally, 18 months following the eliminating of failures caused to 328.2% increase in the revenue of ED (df = 15.9; F = 215; p<0.0001.Conclusion: The findings of the present study shows that failure mode and effect analysis, can be used as a safe and effected method to reduce the expenses of ED and increase its revenue.

    2008-01-01

    Hedging rule policies for reservoir operations accept small deficits in current supply to reduce the probability of a severe water shortage later. This paper expands a theoretical analysis and develops a conceptual two-period model for reservoir operation with hedging that includes uncertain future reservoir inflow explicitly. Extended analysis of the model properties and influencing factors is presented with a general utility function, addressing (1) the starting and ending water availability for hedging, (2) the range of hedging that is related to water demand levels, (3) inflow uncertainty, and (4) evaporation loss. Some intuitive knowledge on reservoir operation is proved or reconfirmed analytically; and new knowledge is derived. This theoretical analysis provides an updated basis for further theoretical study, and the theoretical findings can be used to improve numerical modeling for reservoir operation.

    2015-01-01

    Full Text Available Objectives. A free-standing emergency department (FSED is a facility that provides comprehensive emergency medical care similar to a traditional emergency department but is not attached to a hospital campus. Medical scribes are increasingly likely to work in free-standing emergency departments. The purpose of this study was to retrospectively investigate the benefits of a scribe program in an FSED. Methods. A retrospective, Institutional Review Board-approved analysis from December 1, 2013, to February 1, 2015, of free-standing emergency department medical data was extracted to determine if scribed charts resulted in increased revenue and improved throughput. Results. When scribes are present in the FSED there is a small, but statistically significant, decrease in time from patient arrival to provider by 2.74 minutes. Scribed charts collected $4.69 more per chart and resulted in an increase in productivity. Incremental cost effectiveness ratios resulted in proven cost-utility with a net-positive effect. Conclusion. While there are some gains in terms of operational metrics and provider productivity with the addition of scribes to a free-standing emergency department, there is a net-positive financial impact of scribes. Implementing a scribe program at a FSED is cost-effective and justified from both an operational and a financial analysis.

    An environmental analysis of the operation of the Oak Ridge National Laboratory (ORNL) facilities in Bethel Valley and Melton Valley was conducted to present to the public information concerning the extent to which recognizable effects, or potential effects, on the environment may occur. The analysis addresses current operations of the ORNL X-10 site and completed operations that may continue to have residual effects. Solid wastes from ORNL operations at the Y-12 site which are transported to the X-10 site for burial (e.g., Biology Division animal wastes) are included as part of X-10 site operation. Socioeconomic effects are associated primarily with the communities where employees live and with the Knoxville Bureau of Economic Analysis economic area as a whole. Therefore, ORNL employees at both Y-12 and X-10 sites are included in the ORNL socioeconomic impact analysis. An extensive base of environmental data was accumulated for this report. Over 80 reports related to ORNL facilities and/or operations are cited as well as many open-literature citations. Environmental effects of the operation of ORNL result from operational discharges from the onsite facilities; construction and/or modification of facilities, transportation to and from the site of persons, goods and services; socioeconomic impacts to the local, regional, and general population; and accidental discharges if they should occur. Operational discharges to the environnment are constrained by federal, state, and local regulations and by criteria established by the US Department of Energy to minimize adverse impacts. It is the purpose of this document to evaluate the operation of the ORNL insofar as impacts beyond the site boundary may occur or have the potential for occurrence.

  6. Oral ondansetron administration in emergency departments to children with gastroenteritis: an economic analysis.

    Full Text Available BACKGROUND: The use of antiemetics for children with vomiting is one of the most controversial decisions in the treatment of gastroenteritis in developed countries. Ondansetron, a selective serotonin receptor antagonist, has been found to be effective in improving the success of oral rehydration therapy. However, North American and European clinical practice guidelines continue to recommend against its use, stating that evidence of cost savings would be required to support ondansetron administration. Thus, an economic analysis of the emergency department administration of ondansetron was conducted. The primary objective was to conduct a cost analysis of the routine administration of ondansetron in both the United States and Canada. METHODS AND FINDINGS: A cost analysis evaluated oral ondansetron administration to children presenting to emergency departments with vomiting and dehydration secondary to gastroenteritis from a societal and health care payer's perspective in both the US and Canada. A decision tree was developed that incorporated the frequency of vomiting, intravenous insertion, hospitalization, and emergency department revisits. Estimates of the monetary costs associated with ondansetron use, intravenous rehydration, and hospitalization were derived from administrative databases or emergency department use. The economic burden in children administered ondansetron plus oral rehydration therapy was compared to those not administered ondansetron employing deterministic and probabilistic simulations. We estimated the costs or savings to society and health care payers associated with the routine administration of ondansetron. Sensitivity analyses considered variations in costs, treatment effects, and exchange rates. In the US the administration of ondansetron to eligible children would prevent approximately 29,246 intravenous insertions and 7,220 hospitalizations annually. At the current average wholesale price, its routine administration

    Adverse drug events (ADEs) among patients self-administering medications in home/community settings are a common cause of emergency department (ED) visits, but the causes of these ambulatory ADEs remain unclear. Root cause analysis, rarely applied in outpatient settings, may reveal the underlying factors that contribute to adverse events. To elicit patient and provider perspectives on ambulatory ADEs and apply root cause analysis methodology to identify cross-cutting themes among these events. Emergency department clinical pharmacists screened, identified, and enrolled a convenience sample of adult patients 18 years or older who presented to a single, urban, academic ED with symptoms or diagnoses consistent with suspected ADEs. Semistructured phone interviews were conducted with the patients and their providers. We conducted a qualitative analysis. We applied a prespecified version of the injury prevention framework (deductive coding), identifying themes relating to the agent (drug), host (patient), and environment (social and health systems). These themes were used to construct a root cause analysis for each ADE. From 18 interviews overall, we identified the following themes within the injury prevention framework. Agent factors included high-risk drugs, narrow therapeutic indices, and uncommon severe effects. Host factors included patient capacity or understanding of how to use medications, awareness of side effects, mistrust of the medical system, patients with multiple comorbidities, difficult risk-benefit assessments, and high health-care users. Environmental factors included lack of social support, and health systems issues included access to care, encompassing medication availability, access to specialists, and a lack of continuity and communication among prescribing physicians. Root cause analysis revealed multiple underlying factors relating to agent, host, and environment for each event. Patient and physician perspectives can inform a root cause analysis

    Acquisition and analysis of open source information plays an increasingly important role in the IAEA strengthened safeguards system. The Agency's focal point for open source information collection and analysis is the Division of Safeguards Information Management (SGIM) within the IAEA Department of Safeguards. In parallel with the approval of the Model Additional Protocol in 1997, a new centre of information acquisition and analysis expertise was created within SGIM. By acquiring software, developing databases, retraining existing staff and hiring new staff with diverse analytical skills, SGIM is pro actively contributing to the future implementation of information-driven safeguards in collaboration with other Divisions within the Department of Safeguards. Open source information support is now fully integrated with core safeguards processes and activities, and has become an effective tool in the work of the Department of Safeguards. This provides and overview of progress realized through the acquisition and use of open source information in several thematic areas: evaluation of additional protocol declarations; support to the State Evaluation process; in-depth investigation of safeguards issues, including assisting inspections and complementary access; research on illicit nuclear procurement networks and trafficking; and monitoring nuclear developments. Demands for open source information have steadily grown and are likely to continue to grow in the future. Coupled with the enormous growth and accessibility in the volume and sources of information, new challenges are presented, both technical and analytical. This paper discusses actions taken and future plans for multi-source and multi-disciplinary analytic integration to strengthen confidence in safeguards conclusions - especially regarding the absence of undeclared nuclear materials and activities.

    Hawe, Simon; Diepold, Klaus

    2012-01-01

    Exploiting a priori known structural information lies at the core of many image reconstruction methods that can be stated as inverse problems. The synthesis model, which assumes that images can be decomposed into a linear combination of very few atoms of some dictionary, is now a well established tool for the design of image reconstruction algorithms. An interesting alternative is the analysis model, where the signal is multiplied by an analysis operator and the outcome is assumed to be the sparse. This approach has only recently gained increasing interest. The quality of reconstruction methods based on an analysis model severely depends on the right choice of the suitable operator. In this work, we present an algorithm for learning an analysis operator from training images. Our method is based on an $\\ell_p$-norm minimization on the set of full rank matrices with normalized columns. We carefully introduce the employed conjugate gradient method on manifolds, and explain the underlying geometry of the constrai...

    2014-01-01

    Current and forward-looking resource constraints within the federal health system and general health market are generating questions of fiscal or economic viability of a number of programs including graduate education. This article establishes a framework for assessing economic value among graduate health-related programs within the Army Medical Department. The findings of this analysis indicated that the programs evaluated in the study generate positive economic value based on a market-based valuation of extrinsic benefits compared to extrinsic costs for conducting graduate education within each of the programs. Suggestions for future research and policy application are also discussed.

     To measure incidence of early death after discharge from emergency departments, and explore potential sources of variation in risk by measurable aspects of hospitals and patients.  Retrospective cohort study.  Claims data from the US Medicare program, covering visits to an emergency department, 2007-12.  Nationally representative 20% sample of Medicare fee for service beneficiaries. As the focus was on generally healthy people living in the community, patients in nursing facilities, aged ≥90, receiving palliative or hospice care, or with a diagnosis of a life limiting illnesses, either during emergency department visits (for example, myocardial infarction) or in the year before (for example, malignancy) were excluded.  Death within seven days after discharge from the emergency department, excluding patients transferred or admitted as inpatients.  Among discharged patients, 0.12% (12 375/10 093 678, in the 20% sample over 2007-12) died within seven days, or 10 093 per year nationally. Mean age at death was 69. Leading causes of death on death certificates were atherosclerotic heart disease (13.6%), myocardial infarction (10.3%), and chronic obstructive pulmonary disease (9.6%). Some 2.3% died of narcotic overdose, largely after visits for musculoskeletal problems. Hospitals in the lowest fifth of rates of inpatient admission from the emergency department had the highest rates of early death (0.27%)-3.4 times higher than hospitals in the highest fifth (0.08%)-despite the fact that hospitals with low admission rates served healthier populations, as measured by overall seven day mortality among all comers to the emergency department. Small increases in admission rate were linked to large decreases in risk. In multivariate analysis, emergency departments that saw higher volumes of patients (odds ratio 0.84, 95% confidence interval 0.81 to 0.86) and those with higher charges for visits (0.75, 0.74 to 0.77) had significantly fewer deaths.

  13. Controllability Analysis for Operation Margin of Zone 3 Impedance Relay

    Science.gov (United States)

    Li, Shenghu; Yorino, Naoto; Zoka, Yoshifumi

    Undesirable operation of zone 3 impedance relay (mho relays) is a possible factor for causing cascading failure as seen in several previous large scale blackouts, where power flow redistribution and power swing caused by outage or switching operations satisfy the condition for the relay operation. So far, the condition itself has not fully been investigated, and therefore, there has been little attempt to avoid the relay operation by means of direct power flow control. This paper analyzes the condition for zone 3 relay operation from the viewpoint of its sensitivity to power flow. An operating margin for security is defined for each relay to carry out effective monitoring. It is newly pointed out that undesirable operation can be effectively avoided by reactive power controls as well as real power controls. The method to compute the operation margin is also given through the analysis of the optimal Var location to control the operation margin. Effectiveness of the proposed method is demonstrated using the IEEE test systems.

    The modal parameters of linear vehicle system are analyzed by the theoretical modal parameter analysis method first, and then SSI based on operational conditions is presented to form the estimation formula of modal parameters of linear vehicle system. At last, the modal parameters of linear vehicle system are identified by SSI after its vibration test under operational conditions, and are simultaneously compared to the results obtained by the theoretical modal parameter analysis method. Comparison results show discrepancies of 0.61~8.32 percent on modal frequencies and 3.86~11.61 percent on modal damping ratios, which implies that SSI based on the operational condition is feasible and effective, and has comparatively higher precision to meet the needs of engineering.

    Small signal stability problems are one of the major threats to grid stability and reliability in the U.S. power grid. An undamped mode can cause large-amplitude oscillations and may result in system breakups and large-scale blackouts. There have been several incidents of system-wide oscillations. Of those incidents, the most notable is the August 10, 1996 western system breakup, a result of undamped system-wide oscillations. Significant efforts have been devoted to monitoring system oscillatory behaviors from measurements in the past 20 years. The deployment of phasor measurement units (PMU) provides high-precision, time-synchronized data needed for detecting oscillation modes. Measurement-based modal analysis, also known as ModeMeter, uses real-time phasor measurements to identify system oscillation modes and their damping. Low damping indicates potential system stability issues. Modal analysis has been demonstrated with phasor measurements to have the capability of estimating system modes from both oscillation signals and ambient data. With more and more phasor measurements available and ModeMeter techniques maturing, there is yet a need for methods to bring modal analysis from monitoring to actions. The methods should be able to associate low damping with grid operating conditions, so operators or automated operation schemes can respond when low damping is observed. The work presented in this report aims to develop such a method and establish a Modal Analysis for Grid Operation (MANGO) procedure to aid grid operation decision making to increase inter-area modal damping. The procedure can provide operation suggestions (such as increasing generation or decreasing load) for mitigating inter-area oscillations.

    Modal filtration in the field of damage detection has many advantages, including: its autonomous operation (without the interaction of qualified staff), low computational cost and low sensitivity to changes in external conditions. However, the main drawback of this group of damage detection methods is its limited applicability to operational data. In this paper a method of modal filter formulation from the in-operational data is described. The basis for this approach is FRFs synthesis using knowledge of the operational modal model. For that purpose a method of operational mode shape scaling is described. This is based on the measurements of several FRFs of the object. The method is then applied to the construction of modal filters and modal filtration. Additionally, the study presents verification of the method using data obtained from simulation and laboratory experiments. Verification consisted of comparing the results of modal filtering based on classical experimental modal analysis with the results of the approach proposed in the work.

    Modal filtration in the field of damage detection has many advantages, including: its autonomous operation (without the interaction of qualified staff), low computational cost and low sensitivity to changes in external conditions. However, the main drawback of this group of damage detection methods is its limited applicability to operational data. In this paper a method of modal filter formulation from the in-operational data is described. The basis for this approach is FRFs synthesis using knowledge of the operational modal model. For that purpose a method of operational mode shape scaling is described. This is based on the measurements of several FRFs of the object. The method is then applied to the construction of modal filters and modal filtration. Additionally, the study presents verification of the method using data obtained from simulation and laboratory experiments.

    Software reliability was estimated based on NHPP software reliability growth models. Testing reliability and operational reliability may be essentially different. On the basis of analyzing similarities and differences of the testing phase and the operational phase, using the concept of operational reliability and the testing reliability, different forms of the comparison between the operational failure ratio and the predicted testing failure ratio were conducted, and the mathematical discussion and analysis were performed in detail. Finally, software optimal release was studied using software failure data. The results show that two kinds of conclusions can be derived by applying this method, one conclusion is to continue testing to meet the required reliability level of users, and the other is that testing stops when the required operational reliability is met, thus the testing cost can be reduced.

    The results are cited of a study of the operation of operational oil and gas wells. A hydraulic system of operational wells is identified for the first time, which consists of elements of a stratum, well and surface equipment system. After a brief presentation of the rating methods which describe the operation of the elements, the methods for hydraulic analysis of the complete system are detailed. After theoretical presentation of the methods, the course of computer (EVM) programs, developed for practical purposes, is shown. These programs may be used to solve two basic problems in gusher extraction of oil: identification of the maximal flow rate of a gusher well and the operational point of a well which has a wellhead coupling.

    RHIC has been successfully operated for 5 years as a collider for different species, ranging from heavy ions including gold and copper, to polarized protons. We present a critical analysis of reliability data for RHIC that not only identifies the principal factors limiting availability but also evaluates critical choices at design times and assess their impact on present machine performance. RHIC availability data are typical when compared to similar high-energy colliders. The critical analysis of operations data is the basis for studies and plans to improve RHIC machine availability beyond the 50-60% typical of high-energy colliders.

    This paper raises the comparison method of operational stages of the real estate market. In order to select similar operational stages, we established an analysis model by applying fuzzy grade-of-membership clustering in this paper. Firstly, we select the materials information of the real estate market in America, Germany and Japan. Secondly, the real estate markets of America, Germany and Japan are divided into several different stages. Lastly, we apply the method of fuzzy grade-of-membership clustering to select comparable stages. The result of analysis indicates that the real estate market of Japan and Germany (1960-1980) are similar to the market in China.

    In this paper, the analysis is performed to evaluate the time to core uncovery and core damage as well as the time to core boiling. To analyze thermal hydraulic behaviors during refueling pool operation, RELAP5/MOD3.3 is used adopting the Henry-Fauske (H-F) critical flow model. The input modeling method adopts the method of SFP. The purpose of the analysis is to study the major results and T-H behaviors regarding to safety aspect during LODHR event at the refueling pool operation. In the present low power and shutdown (LPSD) probabilistic safety assessment (PSA) thermal hydraulic (T-H) analysis for dealing with various different plant operational states (POSs), the T-H analysis for the duration of refueling pool operation is omitted as it is considered less severe procedure during overhaul period for optimized power reactor 1000 (OPR1000). Instead only spent fuel pool analysis has been performed representing refueling operation mode (operation mode 6). However, in NUREG-1449, the NRC staff identified twelve technical issues that warrant further evaluation regarding shutdown and low power operation at U.S commercial nuclear power plants. One of issues identified for further evaluation is to evaluate the effect of PWR upper internals, that is, the PWR upper internals may inhibit water in the refueling pool from entering the core during a loss of decay heat removal event (LODHR). Per a commission paper (SECY-91-283) which reported progress to date on the evaluation, the NRC staff requested to address this safety issue by performing a quantitative and qualitative analysis. An analysis of LODHR was performed for advanced power reactor 1400 (APR1400) but it was focused to evaluate the initiation time of core boiling. As the results of the analysis for the LODHR during refueling pool operation, even though the core boiling is occurred in 15 minutes, there is enough water to cover the core and it prevents the core from damaging. The time is taken more than 4 days until the

    The economic crisis, the growing healthcare demand, and Defensive Medicine wastefulness, strongly recommend the restructuring of the entire medical network. New health technology, such as bedside ultrasonography, might successfully integrate the clinical approach optimizing the use of limited resources, especially in a person-oriented vision of medicine. Bedside ultrasonography is a safe and reliable technique, with worldwide expanding employment in various clinical settings, being considered as "the stethoscope of the 21st century". However, at present, bedside ultrasonography lacks economic analysis. We performed a Cost-Benefit Analysis "ex ante", with a break-even point computing, of bedside ultrasonography implementation in an Internal Medicine department in the mid-term. Number and kind estimation of bedside ultrasonographic studies were obtained by a retrospective study, whose data results were applied to the next 3-year period (foresight study). All 1980 foreseen bedside examinations, with prevailing multiorgan ultrasonographic studies, were considered to calculate direct and indirect costs, while specific and generic revenues were considered only after the first semester. Physician professional training, equipment purchase and working time represented the main fixed and variable cost items. DRG increase/appropriateness, hospitalization stay shortening and reduction of traditional ultrasonography examination requests mainly impacted on calculated revenues. The break-even point, i.e. the volume of activity at which revenues exactly equal total incurred costs, was calculated to be 734 US examinations, corresponding to € 81,998 and the time considered necessary to reach it resulting 406 days. Our economic analysis clearly shows that bedside ultrasonography implementation in clinical daily management of an Internal Medicine department can produce consistent savings, or economic profit according to managerial choices (i.e., considering public or private targets

    2012-01-01

    We consider the problem of learning a low-dimensional signal model from a collection of training samples. The mainstream approach would be to learn an overcomplete dictionary to provide good approximations of the training samples using sparse synthesis coefficients. This famous sparse model has a less well known counterpart, in analysis form, called the cosparse analysis model. In this new model, signals are characterised by their parsimony in a transformed domain using an overcomplete (linear) analysis operator. We propose to learn an analysis operator from a training corpus using a constrained optimisation framework based on L1 optimisation. The reason for introducing a constraint in the optimisation framework is to exclude trivial solutions. Although there is no final answer here for which constraint is the most relevant constraint, we investigate some conventional constraints in the model adaptation field and use the uniformly normalised tight frame (UNTF) for this purpose. We then derive a practical lear...

    One of the important activities of ESA Science Operations Centre is to provide Data Analysis Software (DAS) to enable users and scientists to process data further to higher levels. During operations and post-operations, Data Analysis Software (DAS) is fully maintained and updated for new OS and library releases. Nonetheless, once a Mission goes into the "legacy" phase, there are very limited funds and long-term preservation becomes more and more difficult. Building on Virtual Machine (VM), Cloud computing and Software as a Service (SaaS) technologies, this project has aimed at providing long-term preservation of Data Analysis Software for the following missions: - PIA for ISO (1995) - SAS for XMM-Newton (1999) - Hipe for Herschel (2009) - EXIA for EXOSAT (1983) Following goals have guided the architecture: - Support for all operations, post-operations and archive/legacy phases. - Support for local (user's computer) and cloud environments (ESAC-Cloud, Amazon - AWS). - Support for expert users, requiring full capabilities. - Provision of a simple web-based interface. This talk describes the architecture, challenges, results and lessons learnt gathered in this project.

    1997-01-01

    We characterize classes of linear maps between operator spaces $E$, $F$ which factorize through maps arising in a natural manner via the Pisier vector-valued non-commutative $L^p$ spaces $S_p[E^*]$ based on the Schatten classes on the separable Hilbert space $l^2$. These classes of maps can be viewed as quasi-normed operator ideals in the category of operator spaces, that is in non-commutative (quantized) functional analysis. The case $p=2$ provides a Banach operator ideal and allows us to characterize the split property for inclusions of $W^*$-algebras by the 2-factorable maps. The various characterizations of the split property have interesting applications in Quantum Field Theory.

    This Contingency Plan identifies personnel responsibilities, emergency equipment, and required actions necessary to mitigate potential incidents at the Waste Accumulation Area(s) (WAA)(s) located at the Lawrence Livermore National Laboratory (LLNL) Experimental Test Site 300 (Site 300) as shown in Figure 1. This Plan is designed to prepare personnel to minimize hazards to human health and the environment from fires, explosions, or any sudden or nonsudden release of hazardous, radioactive, or mixed waste constituents to the air, ground surface, or water from waste stored in the WAA(s). The LLNL Site 300 currently has one WAA. The location of the WAA is shown in Figure 2 and identified in Table 1. As programmatic needs change, it may become necessary to establish additional WAAs at Site 300. The WAA is a small, regularly monitored storage area where waste can be accumulated and stored temporarily. Hazardous and mixed waste can be stored or accumulated in a WAA for up to 90 days, after which it must be transferred to a Department of Toxic Substances Control (DTSC) authorized onsite treatment or storage facility or an authorized offsite treatment, storage, or disposal facility (TSDF). The onsite TSDFs authorized by DTSC are managed by the Radioactive and Hazardous Waste Management (RHWM) Division and by the Chemistry and Materials Science Directorate (CMS) at Site 300. Hazardous, radioactive, or mixed waste is referred to as ''waste'' in this document. Radioactive waste has been included in this Plan as a ''Best Management Practice'' to aid in response, where appropriate. However, radioactive waste is not regulated by DTSC under this Plan. This Contingency Plan is divided into two parts: (1) The first part, referred to as the ''General Plan'', is general information that is applicable to the existing and any subsequent WAAs. The General Plan includes Sections 1-7 and Appendices A-C. (2) The second part

    Mohanty, P.; Rixen, D. J.

    2004-02-01

    Modal operational analysis methods are procedures to identify modal parameters of structures from the response to unknown random excitations existing on buildings and in machines during operation. In many practical cases, in addition to the random loads, harmonic excitations are also present due for instance to rotating components. If the frequency of the harmonic component of the input is close to an eigenfrequency of the system, operational modal analysis procedures fail to identify the modal parameters accurately. Therefore, we propose a modification of the least-square complex exponential identification procedure to include explicitly the harmonic component. In that way, the modal parameters can be identified properly. We illustrate the efficiency of the proposed approach on the example of a beam structure excited by multi-harmonic loads superposed on random excitation.

    Full Text Available The purpose of this research was to observe the effect of the age of the organization department in Padang State University on performance through human capital, structural capital and relational capital. The sample is all of department in Padang State University, which is 33 departments. The data were collected through questionnaires and analyzed using partial least squares (PLS. The results showed that the age of the department is not direct and significant impact on the department performance. While the age departments significantly affect the department's human capital, structural capital and relational capital. Furthermore, the human capital, structural capital and relational capital significantly positive affect the department performance. This research failed to prove the existence of variable human capital, structural capital and relational capital as a mediating variable but serves as an intervening variable. Its means that age of department performance cannot determine performance without increasing the human capital, structural capital and relational capital.

  9. Improved Principal Component Analysis for Anomaly Detection: Application to an Emergency Department

    KAUST Repository

    Harrou, Fouzi

    2015-07-03

    Monitoring of production systems, such as those in hospitals, is primordial for ensuring the best management and maintenance desired product quality. Detection of emergent abnormalities allows preemptive actions that can prevent more serious consequences. Principal component analysis (PCA)-based anomaly-detection approach has been used successfully for monitoring systems with highly correlated variables. However, conventional PCA-based detection indices, such as the Hotelling’s T2T2 and the Q statistics, are ill suited to detect small abnormalities because they use only information from the most recent observations. Other multivariate statistical metrics, such as the multivariate cumulative sum (MCUSUM) control scheme, are more suitable for detection small anomalies. In this paper, a generic anomaly detection scheme based on PCA is proposed to monitor demands to an emergency department. In such a framework, the MCUSUM control chart is applied to the uncorrelated residuals obtained from the PCA model. The proposed PCA-based MCUSUM anomaly detection strategy is successfully applied to the practical data collected from the database of the pediatric emergency department in the Lille Regional Hospital Centre, France. The detection results evidence that the proposed method is more effective than the conventional PCA-based anomaly-detection methods.

    1995-05-01

    The Idaho National Engineering Laboratory (INEL) is currently storing a large quantity of alpha contaminated mixed low level waste which will require treatment prior to disposal. The DOE Idaho Operations Office (DOE-ID) recognized that current knowledge and funding were insufficient to directly pursue services for the requisite treatment. Therefore, it was decided that private sector studies would be funded to clarify cost, regulatory, technology, and contractual issues associated with procuring treatment services. This report analyzes the three private sector studies procured and recommends a path forward for DOE in procuring retrieval, assay, characterization, and treatment services for INEL transuranic and alpha contaminated mixed low level waste. This report was prepared by a team of subject matter experts from the INEL referred to as the DOE-ID Evaluation Team.

    Employing new health information technologies while concurrently providing quality patient care and reducing risk is a major challenge in all health care sectors. In this study, we investigated the usability gaps in the Emergency Department Information System (EDIS) as ten nurses differentiated by two experience levels, namely six expert nurses and four novice nurses, completed two lists of nine scenario-based tasks. Standard usability tests using video analysis, including four sets of performance measures, a task completion survey, the system usability scale (SUS), and sub-task analysis were conducted in order to analyze usability gaps between the two nurse groups. A varying degree of usability gaps were observed between the expert and novice nurse groups, as novice nurses completed the tasks both less efficiently, and expressed less satisfaction with the EDIS. The most interesting finding in this study was the result of 'percent task success rate,' the clearest performance measure, with no substantial difference observed between the two nurse groups. Geometric mean values between expert and novice nurse groups for this measure were 60% vs. 62% in scenario 1 and 66% vs. 55% in scenario 2 respectively, while there were some marginal to substantial gaps observed in other performance measures. In addition to performance measures and the SUS, sub-task analysis highlighted navigation pattern differences between users, regardless of experience level. This study will serve as a baseline study for a future comparative usability evaluation of EDIS in other institutions with similar clinical settings.

  1. Film reject analysis and image quality in diagnostic Radiology Department of a Teaching hospital in Ghana

    2014-10-01

    Full Text Available Patients usually undergo repeated X-ray examinations after their initial X-ray radiographs are rejected due to poor image quality. This subjects the patients to an excess radiation exposure and extra cost and necessitates the need to investigate the causes of reject. The use of reject analysis as part of the overall quality assurance programs in clinical radiography and radiology services is vital in the evaluation of image quality of a well-established practice. It is shown that, in spite of good quality control maintained by the Radiology Department of a Teaching hospital in Ghana, reject analysis performed on a number of radiographic films developed indicated 14.1% reject rate against 85.9% accepted films. The highest reject rate was 57.1 ± 0.7% which occurs in cervical spine and the lowest was7.7 ± 0.5% for lumbar spine. The major factors contributing to film rejection were found to be over exposure and patient positioning in cervical spine examinations. The most frequent examination was chest X-ray which accounts for about 42.2% of the total examinations. The results show low reject rates by considering the factors for radiographic rejection analysis in relation to both equipment functionality and film development in the facility.

    We present a risk analysis undertaken to mitigate problems in relation to the unintended deployment of slides under normal operations within a commercial airline. This type of incident entails relevant costs for the airline industry. After assessing the likelihood and severity of its consequences, we conclude that such risks need to be managed. We then evaluate the effectiveness of various countermeasures, describing and justifying the chosen ones. We also discuss several issues faced when implementing and communicating the proposed measures, thus fully illustrating the risk analysis process. © 2015 Society for Risk Analysis.

    Nakamura, Kenji; Ichinokura, Osamu

    In this paper, we describe the basis of a magnetic circuit method and introduce a reluctance network analysis (RNA) proposed by authors. The RNA, which is based on the magnetic circuit method, has some suitable merits for simulating electrical machineries such as a simple analytical model, ease of coupled analysis with electrical circuits, motion, and thermal fields. In addition to these merits, a general-purpose circuit simulator like “SPICE" can be utilized as a solver. We present some applications of the RNA to operation analysis for an orthogonal-core, a switched reluctance motor, and a permanent magnet generator.

  4. Department of Energy seismic siting and design decisions: Consistent use of probabilistic seismic hazard analysis

    Energy Technology Data Exchange (ETDEWEB)

    Kimball, J.K.; Chander, H.

    1997-02-01

    The Department of Energy (DOE) requires that all nuclear or non-nuclear facilities shall be designed, constructed and operated so that the public, the workers, and the environment are protected from the adverse impacts of Natural Phenomena Hazards including earthquakes. The design and evaluation of DOE facilities to accommodate earthquakes shall be based on an assessment of the likelihood of future earthquakes occurrences commensurate with a graded approach which depends on the potential risk posed by the DOE facility. DOE has developed Standards for site characterization and hazards assessments to ensure that a consistent use of probabilistic seismic hazard is implemented at each DOE site. The criteria included in the DOE Standards are described, and compared to those criteria being promoted by the staff of the Nuclear Regulatory Commission (NRC) for commercial nuclear reactors. In addition to a general description of the DOE requirements and criteria, the most recent probabilistic seismic hazard results for a number of DOE sites are presented. Based on the work completed to develop the probabilistic seismic hazard results, a summary of important application issues are described with recommendations for future improvements in the development and use of probabilistic seismic hazard criteria for design of DOE facilities.

  5. Analysis and Prediction of Weather Impacted Ground Stop Operations

    Wang, Yao Xun

    2014-01-01

    When the air traffic demand is expected to exceed the available airport's capacity for a short period of time, Ground Stop (GS) operations are implemented by Federal Aviation Administration (FAA) Traffic Flow Management (TFM). The GS requires departing aircraft meeting specific criteria to remain on the ground to achieve reduced demands at the constrained destination airport until the end of the GS. This paper provides a high-level overview of the statistical distributions as well as causal factors for the GSs at the major airports in the United States. The GS's character, the weather impact on GSs, GS variations with delays, and the interaction between GSs and Ground Delay Programs (GDPs) at Newark Liberty International Airport (EWR) are investigated. The machine learning methods are used to generate classification models that map the historical airport weather forecast, schedule traffic, and other airport conditions to implemented GS/GDP operations and the models are evaluated using the cross-validations. This modeling approach produced promising results as it yielded an 85% overall classification accuracy to distinguish the implemented GS days from the normal days without GS and GDP operations and a 71% accuracy to differentiate the GS and GDP implemented days from the GDP only days.

    1996-12-01

    This report documents the research effort to determine the requirements for new or improved analysis tools to support decisions at the strategic and operational levels for military Operations Other than War (OOTW). The work was performed for the Commander in Chief, U.S. Pacific Command (USCINCPAC). The data collection was based on workshops attended by experts in OOTWs: analysis personnel from each of the Combatant Commands, the Services, the Office of the Secretary of Defense (OSD), the Joint Staff, and other knowledgeable personnel. Further data were gathered from other workshops and conferences and from the literature. The results of this research begin with the creation of a taxonomy of OOTWs: categories of operations, attributes of operations, and tasks requiring analytical support. The tasks are connected to the Joint Staff`s Universal Joint Task List (UJTL). Historical OOTWs are analyzed to produce frequency distributions by category and responsible CINC. The analysis products are synthesized into a list of requirements for analytical tools and definitions of the requirements. The report concludes with a timeline or roadmap for satisfying the requirements.

    2010-07-31

    On October 9, 1996, Bruce Babbitt, then-Secretary of the U.S. Department of the Interior signed the Record of Decision (ROD) on operating criteria for the Glen Canyon Dam (GCD). Criteria selected were based on the Modified Low Fluctuating Flow (MLFF) Alternative as described in the Operation of Glen Canyon Dam, Colorado River Storage Project, Arizona, Final Environmental Impact Statement (EIS) (Reclamation 1995). These restrictions reduced the operating flexibility of the hydroelectric power plant and therefore its economic value. The EIS provided impact information to support the ROD, including an analysis of operating criteria alternatives on power system economics. This ex post study reevaluates ROD power economic impacts and compares these results to the economic analysis performed prior (ex ante) to the ROD for the MLFF Alternative. On the basis of the methodology used in the ex ante analysis, anticipated annual economic impacts of the ROD were estimated to range from approximately $15.1 million to $44.2 million in terms of 1991 dollars ($1991). This ex post analysis incorporates historical events that took place between 1997 and 2005, including the evolution of power markets in the Western Electricity Coordinating Council as reflected in market prices for capacity and energy. Prompted by ROD operational restrictions, this analysis also incorporates a decision made by the Western Area Power Administration to modify commitments that it made to its customers. Simulated operations of GCD were based on the premise that hourly production patterns would maximize the economic value of the hydropower resource. On the basis of this assumption, it was estimated that economic impacts were on average $26.3 million in $1991, or $39 million in $2009.

    Silicon avalanche photodiodes (APDs) are sensitive to operating temperature fluctuations and are also susceptible to radiation flux expected in satellite-based quantum experiments. We introduce a low power voltage adjusting mechanism to overcome the effects of in-orbit temperature fluctuations. We also present data on the performance of Si APDs after irradiation (γ-ray and proton beam). Combined with an analysis of expected orbital irradiation, we propose that a Si APD in a 400 km equatorial orbit may operate beyond the lifetime of the satellite.

    2017-01-01

    Blood gas analysis plays an important role in the initial assessment of a patient in the emergency ward. We present three different patient cases to illustrate when to opt for a venous or an arterial blood gas analysis. Arterial punctures are more painful and carry a higher risk of complications compared to venous punctures. It is possible to use a venous blood gas to screen for acute acid/base disturbances. Ventilatory compensation or anion gap cannot be calculated reliably with a venous blood gas. On the other hand, the diagnosis diabetic keto-acidosis can be made with a venous blood gas; this mode of sampling can also be used for lactate measurement at the emergency department as an independent prognostic marker for mortality. Venous blood gas analyses are not able to assess oxygenation. Pulse oximetry is a non-invasive alternative for arterial blood gas sampling. The use of a venous blood gas to assess a patient's ventilation is limited, whereas it can be used to diagnose carbomonoxide intoxication or methaemoglobinaemia.

  14. Application of human error analysis to aviation and space operations

    1998-03-01

    For the past several years at the Idaho National Engineering and Environmental Laboratory (INEEL) the authors have been working to apply methods of human error analysis to the design of complex systems. They have focused on adapting human reliability analysis (HRA) methods that were developed for Probabilistic Safety Assessment (PSA) for application to system design. They are developing methods so that human errors can be systematically identified during system design, the potential consequences of each error can be assessed, and potential corrective actions (e.g. changes to system design or procedures) can be identified. The primary vehicle the authors have used to develop and apply these methods has been a series of projects sponsored by the National Aeronautics and Space Administration (NASA) to apply human error analysis to aviation operations. They are currently adapting their methods and tools of human error analysis to the domain of air traffic management (ATM) systems. Under the NASA-sponsored Advanced Air Traffic Technologies (AATT) program they are working to address issues of human reliability in the design of ATM systems to support the development of a free flight environment for commercial air traffic in the US. They are also currently testing the application of their human error analysis approach for space flight operations. They have developed a simplified model of the critical habitability functions for the space station Mir, and have used this model to assess the affects of system failures and human errors that have occurred in the wake of the collision incident last year. They are developing an approach so that lessons learned from Mir operations can be systematically applied to design and operation of long-term space missions such as the International Space Station (ISS) and the manned Mars mission.

    Dion, J.-L.; Tawfiq, I.; Chevallier, G.

    2012-01-01

    This work is a contribution in the field of Operational Modal Analysis to identify the modal parameters of mechanical structures using only measured responses. The study deals with structural responses coupled with harmonic components amplitude and frequency modulated in a short range, a common combination for mechanical systems with engines and other rotating machines in operation. These harmonic components generate misleading data interpreted erroneously by the classical methods used in OMA. The present work attempts to differentiate maxima in spectra stemming from harmonic components and structural modes. The detection method proposed is based on the so-called Optimized Spectral Kurtosis and compared with others definitions of Spectral Kurtosis described in the literature. After a parametric study of the method, a critical study is performed on numerical simulations and then on an experimental structure in operation in order to assess the method's performance.

    In this paper four wireless sensor network operating systems are compared in terms of power consumption. The analysis takes into account the most common operating systems—TinyOS v1.0, TinyOS v2.0, Mantis and Contiki—running on Tmote Sky and MICAz devices. With the objective of ensuring a fair evaluation, a benchmark composed of four applications has been developed, covering the most typical tasks that a Wireless Sensor Network performs. The results show the instant and average current consumption of the devices during the execution of these applications. The experimental measurements provide a good insight into the power mode in which the device components are running at every moment, and they can be used to compare the performance of different operating systems executing the same tasks.

    2011-07-01

    This tutorial paper aims to introduce the topic of operational modal analysis to non-specialists on the subject. First of all, it is stressed the relevance of this experimental technique particularly in the assessment of important civil infrastructure. Then, after a synthesis of required theoretical background, three of the most powerful algorithms for output-only modal identification are presented. The several steps of these identification procedures are illustrated with the processing of data collected on a concrete arch bridge with a span of 280 m. As the use of operational modal analysis in the context of structural health monitoring is a subject under active research, this theme is also introduced and briefly exemplified with data continuously recorded at the same bridge.

  2. Transmissibility-Based Operational Modal Analysis: Enhanced Stabilisation Diagrams

    Directory of Open Access Journals (Sweden)

    Gert De Sitter

    2012-01-01

    Full Text Available Recently it has been shown that also transmissibilities can be used to identify the modal parameters. This approach has several advantages: because of the deterministic character of the transmissibility functions, the estimated parameters are more accurate than the results obtained with the power spectra based operational modal analysis techniques. Another advantage is that the transmissibility functions do not depend on the colouring of the unknown forces. A disadvantage of the transmissibility based operational modal analysis techniques is that non-physical modes show up in the stabilisation diagrams. In this contribution it will first be shown that those non-physical modes will show up when traditional stabilisation diagrams are used. In a second step, a new approach of selecting the physical modes out of a set of estimated modes will be discussed and the new approach will be validated using data generated with an acoustical Finite Element Model. Finally, the approach will be validated using real acoustical data.

    A frequency and spatial domain decomposition method (FSDD) for operational modal analysis (OMA) is presented in this paper, which is an extension of the complex mode indicator function (CMIF) method for experimental modal analysis (EMA). The theoretical background of the FSDD method is clarified. Singular value decomposition is adopted to separate the signal space from the noise space. Finally, an enhanced power spectrum density (PSD) is proposed to obtain more accurate modal parameters by curve fitting in the frequency domain. Moreover, a simulation case and an application case are used to validate this method.

    Full Text Available Background. Timely pulmonary function testing is crucial to improving diagnosis and treatment of pulmonary diseases. Perceptions of poor access at an academic pulmonary function laboratory prompted analysis of system demand and capacity to identify factors contributing to poor access. Methods. Surveys and interviews identified stakeholder perspectives on operational processes and access challenges. Retrospective data on testing demand and resource capacity was analyzed to understand utilization of testing resources. Results. Qualitative analysis demonstrated that stakeholder groups had discrepant views on access and capacity in the laboratory. Mean daily resource utilization was 0.64 (SD 0.15, with monthly average utilization consistently less than 0.75. Reserved testing slots for subspecialty clinics were poorly utilized, leaving many testing slots unfilled. When subspecialty demand exceeded number of reserved slots, there was sufficient capacity in the pulmonary function schedule to accommodate added demand. Findings were shared with stakeholders and influenced scheduling process improvements. Conclusion. This study highlights the importance of operational data to identify causes of poor access, guide system decision-making, and determine effects of improvement initiatives in a variety of healthcare settings. Importantly, simple operational analysis can help to improve efficiency of health systems with little or no added financial investment.

    Nistor, Victor

    2016-07-01

    We discuss and develop some connections between analysis on singular spaces and operator algebras, as presented in my sequence of four lectures at the conference Noncommutative geometry and applications, Frascati, Italy, June 16-21, 2014. Therefore this paper is mostly a survey paper, but the presentation is new, and there are included some new results as well. In particular, Sections 3 and 4 provide a complete short introduction to analysis on noncompact manifolds that is geared towards a class of manifolds-called "Lie manifolds" -that often appears in practice. Our interest in Lie manifolds is due to the fact that they provide the link between analysis on singular spaces and operator algebras. The groupoids integrating Lie manifolds play an important background role in establishing this link because they provide operator algebras whose structure is often well understood. The initial motivation for the work surveyed here-work that spans over close to two decades-was to develop the index theory of stratified singular spaces. Meanwhile, several other applications have emerged as well, including applications to Partial Differential Equations and Numerical Methods. These will be mentioned only briefly, however, due to the lack of space. Instead, we shall concentrate on the applications to Index theory.

    2016-06-01

    To overcome ill-posed problems in operational transfer path analysis (OTPA), and improve the stability of solutions, this paper proposes a novel OTPA based on Tikhonov regularization, which considers both fitting degrees and stability of solutions. Firstly, fundamental theory of Tikhonov regularization-based OTPA is presented, and comparative studies are provided to validate the effectiveness on ill-posed problems. Secondly, transfer path analysis and source contribution evaluations for numerical cases studies on spherical radiating acoustical sources are comparatively studied. Finally, transfer path analysis and source contribution evaluations for experimental case studies on a test bed with thin shell structures are provided. This study provides more accurate transfer path analysis for mechanical systems, which can benefit for vibration reduction by structural path optimization. Furthermore, with accurate evaluation of source contributions, vibration monitoring and control by active controlling vibration sources can be effectively carried out.

    The current day flight deck operational environment consists of a two-person Captain/First Officer crew. A concept of operations (ConOps) to reduce the commercial cockpit to a single pilot from the current two pilot crew is termed Single Pilot Operations (SPO). This concept has been under study by researchers in the Flight Deck Display Research Laboratory (FDDRL) at the National Aeronautics and Space Administration's (NASA) Ames (Johnson, Comerford, Lachter, Battiste, Feary, and Mogford, 2012) and researchers from Langley Research Centers (Schutte et al., 2007). Transitioning from a two pilot crew to a single pilot crew will undoubtedly require changes in operational procedures, crew coordination, use of automation, and in how the roles and responsibilities of the flight deck and ATC are conceptualized in order to maintain the high levels of safety expected of the US National Airspace System. These modifications will affect the roles and the subsequent tasks that are required of the various operators in the NextGen environment. The current report outlines the process taken to identify and document the tasks required by the crew according to a number of operational scenarios studied by the FDDRL between the years 2012-2014. A baseline task decomposition has been refined to represent the tasks consistent with a new set of entities, tasks, roles, and responsibilities being explored by the FDDRL as the move is made towards SPO. Information from Subject Matter Expert interviews, participation in FDDRL experimental design meetings, and study observation was used to populate and refine task sets that were developed as part of the SPO task analyses. The task analysis is based upon the proposed ConOps for the third FDDRL SPO study. This experiment possessed nine different entities operating in six scenarios using a variety of SPO-related automation and procedural activities required to guide safe and efficient aircraft operations. The task analysis presents the roles and

    Indigenous populations in Latin America have worse health outcomes than their nonindigenous counterparts. Differences in access to and use of biomedical resources may explain some of the observed disparities. Efforts to address these differences could be aided in part by better understanding the socio-medical contexts in which they occur. We performed a qualitative analysis of field notes collected during a 2008 program evaluation of a health post in a rural Maya village in Sololá Department, Guatemala. Forty-one interviews were conducted among a community-based convenience sample of adult men and women. Interviews focused on experiences, perceptions, and behaviors related to the local biomedical and ethnomedical health care resources. Penetrance of the local health post was high, with most (90%) of respondents having accessed it within the prior five years. The prevailing attitude toward the health post was positive. We identified facilitators and barriers to health post use that corresponded with three thematic areas: clinic operations, visits and consultations, and medical resources. Proximity to the home, free consultations and medications, and social support services were among the most commonly cited facilitators. Barriers included limited clinic hours, medication stock-outs, provision of care that did not meet patient expectations, and unavailability of diagnostic tests. In a rural Maya community in Guatemala, operational and quality-based factors, independent of sociocultural considerations, informed the perception of and decision to access biomedical resources. Interventions that address these factors may increase health care utilization and alleviate some of the health disparities that accompany indigeneity in Guatemala and similar contexts.

    Full Text Available The characteristics of Emergency Department (ED attendances due to mental or behavioural health disorders need to be described to enable appropriate development of services. We aimed to describe the epidemiology of mental health-related ED attendances within health care systems free at the point of access, including clinical reason for presentation, previous service use, and patient sociodemographic characteristics.Systematic review and meta-analysis of observational studies describing ED attendances by patients with common mental health conditions.18 studies from seven countries met eligibility criteria. Patients attending due to mental or behavioural health disorders accounted for 4% of ED attendances; a third were due to self-harm or suicidal ideation. 58.1% of attendees had a history of psychiatric illness and up to 58% were admitted. The majority of studies were single site and of low quality so results must be interpreted cautiously.Prevalence studies of mental health-related ED attendances are required to enable the development of services to meet specific needs.

    The US Department of Energy (US-DOE) manages diverse facilities ranging from laboratory complexes to nuclear reactors and waste repositories. It is self-regulating in the areas of radiological safety, occupational protection and environmental disturbances. In these areas the US-DOE has obtained mostly good results, but at high expense by using conservative and unsystematic approaches. In an effort to improve both safety and use of resources a project has been undertaken to understand better how to utilize risk assessment techniques to obtain improved safety outcomes and their regulation. The example of the Test Reactor Area Hot Cell (TRAHC) at the Idaho National Engineering and Environmental Laboratory (INEEL) is the subject of a simple probabilistic risk assessment (PRA) in the areas of radiological releases to the environment and of occupational hazards. To our knowledge this is the first attempt to utilize quantitative risk analyses for management of non-radiological occupational risks. Its purpose is to examine the feasibility of utilizing risk assessment as a technique to supplant the currently employed, less formal, hazard analysis as the basis for allocating safety-related resources. Problems of data and modeling adequacy have proven to be important; results to-date indicate areas where revised resource allocation should be considered. (author)

    2015-04-01

    As part of an ongoing effort to better understand barriers to academic research, we reviewed and analyzed the process of research ethics applications, focusing on ethics approval time, within the Department of Medicine from 2006 to 2011. A total of 1,268 applications for approval to use human subjects in research were included in our analysis. Three variables, risk category (minimal vs. non-minimal risk), type of funding, and year of submission, were statistically significant for prediction of ethics approval time, with risk status being the most important of these. The covariate-adjusted mean time for approval for minimal risk studies (35.7 days) was less than half that of non-minimal risk protocols (76.5 days). Studies funded through a for-profit sponsor had significantly longer approval times than those funded through other means but were also predominantly (87%) non-minimal risk protocols. Further investigations of the reasons underlying the observed differences are needed to determine whether improved training for research ethics board (REB) members and/or greater dialogue with investigators may reduce the lengthy approval times associated with non-minimal risk protocols. © The Author(s) 2015.

    Emergency department (ED) visits for skin symptoms are on the rise. The nature of these visits is not yet well characterized. We sought to conduct a longitudinal analysis comparing patients discharged from the ED with dermatologic primary diagnoses to those with nondermatologic primary diagnoses. Using the California State ED Database, we compared demographic variables and visit characteristics of patients discharged with dermatologic primary diagnoses (International Classification of Diseases, Ninth Revision, Clinical Modification codes 680-709) to those of patients discharged with nondermatologic primary diagnoses from 2005 to 2011. Patients given dermatologic primary diagnoses in the ED were more likely to be male, aged 18 to 54 years, white or Native American, and low income. They tended to be self-pay patients or have Medicaid, to live in less populous areas, and to visit the ED on the weekend. Results from California may not be generalizable nationally. The databases we used were based on administrative records, which have limited clinical detail. The population of patients discharged home from the ED with dermatologic primary diagnoses appears to differ significantly from the population receiving nondermatologic primary diagnoses.

    In attempting to measure the performance of providers in a service industry such as health care, it is crucial that the measurement tool recognize both the efficiency and quality of service provided. We develop a Data Envelopment Analysis (DEA) model to help assess the performance of emergency department (ED) physicians at a partner hospital. The model incorporates efficiency measures as inputs and quality measures as outputs. We demonstrate the importance of a nuanced approach that recognizes the heterogeneity of patients that an ED physician encounters and the important role s/he plays as a mentor for physicians in training. In the study, patients were grouped according to their presenting complaint and ED physicians were assessed on each group separately. Performance variations were evident between physicians within each complaint group as well as between groups. A secondary grouping divided patients based on whether the attending physician was assisted by a trainee. Almost all ED physicians showed better performance scores when not assisted by trainees or ED fellows.

    Objectives. We identified the levels of joint action that led to collaboration between hospitals and local health departments (LHDs) using the hospital’s community health needs assessments (CHNAs). Methods. In 2014, we conducted a content analysis of Missouri nonprofit hospitals (n = 34) CHNAs, and identified hospitals based on previously reported collaboration with LHDs. We coded the content according to the level of joint action. A comparison sample (n = 50) of Missouri nonprofit hospitals provided the basic comparative information on hospital characteristics. Results. Among the hospitals identified by LHDs, 20.6% were “networking,” 20.6% were “coordinating,” 38.2% were “cooperating,” and 2.9% were “collaborating.” Almost 18% of study hospitals had no identifiable level of joint action with LHDs based on their CHNAs. In addition, comparison hospitals were more often part of a larger system (74%) compared with study hospitals (52.9%). Conclusions. The results of our study helped develop a better understanding of levels of joint action from a hospital perspective. Our results might assist hospitals and LHDs in making more informed decisions about efficient deployment of resources for assessment processes and implementation plans. PMID:25689184

    2015-12-01

    Full Text Available Introduction: Late middle-aged and older adults’ share of emergency department (ED visits is increasing more than other age groups. ED visits by individuals with substance-related problems are also increasing. This paper was intended to identify subgroups of individuals aged 50+ by their risk for ED visits by examining their health/mental health status and alcohol use patterns. Methods: Data came from the 2013 National Health Interview Survey’s Sample Adult file (n=15,713. Following descriptive analysis of sample characteristics by alcohol use patterns, latent class analysis (LCA modeling was fit using alcohol use pattern (lifetime abstainers, ex-drinkers, current infrequent/light/ moderate drinkers, and current heavy drinkers, chronic health and mental health status, and past-year ED visits as indicators. Results: LCA identified a four-class model. All members of Class 1 (35% of the sample; lowest-risk group were infrequent/light/moderate drinkers and exhibited the lowest probabilities of chronic health/ mental health problems; Class 2 (21%; low-risk group consisted entirely of lifetime abstainers and, despite being the oldest group, exhibited low probabilities of health/mental health problems; Class 3 (37%; moderate-risk group was evenly divided between ex-drinkers and heavy drinkers; and Class 4 (7%; high-risk group included all four groups of drinkers but more ex-drinkers. In addition, Class 4 had the highest probabilities of chronic health/mental problems, unhealthy behaviors, and repeat ED visits, with the highest proportion of Blacks and the lowest proportions of college graduates and employed persons, indicating significant roles of these risk factors. Conclusion: Alcohol nonuse/use (and quantity of use and chronic health conditions are significant contributors to varying levels of ED visit risk. Clinicians need to help heavy-drinking older adults reduce unhealthy alcohol consumption and help both heavy drinkers and ex

    Shock is defined as a change of circulation which results in hypoxia at the tissue level. Lactate and base deficit (BD) are associated with a high risk of multiple organ dysfunction in trauma patients. In this study we evaluated the influence of early recognition of shock in trauma patients. In a retrospective study, relevant data were collected from the Radboud University Nijmegen Medical Centre (RUNMC) database between January 2009 and December 2010. Vital parameters were taken at the accident scene, and patients were divided into four shock classes. Arterial blood gas analysis was performed on arrival in the emergency department. Statistical analysis was performed with SPSS version 17.0. Statistical significance was assumed at p ≤ 0.05. A total of 255 patients were included. Patients who suffered from prehospital shock, and those who were intubated prior to hospital admittance showed a bad outcome, presenting with a more severe metabolic acidosis, higher ISS and higher mortality. There was a significant difference for bicarbonate and BD between shockclass I + II and shockclass III + IV, respectively 22.7 vs. 19.7 and -3.4 vs. -6.9. Intubated patients had a decreased bicarbonate and BD compared to not intubated patients, respectively 21.81 vs. 23.24 and -5.08 vs. -2.38. Mortality and ISS were higher in patients in shock class III and IV. Significant differences in serum lactate levels were not found. Prehospital shock influences patient outcome; outcome of patients is related to initial shock classification. Further validation of our shock classification, however, is necessary.

    Choreographer is a "moving target defense system", designed to protect against attacks aimed at IP addresses without corresponding domain name system (DNS) lookups. It coordinates actions between a DNS server and a Network Address Translation (NAT) device to regularly change which publicly available IP addresses' traffic will be routed to the protected device versus routed to a honeypot. More details about how Choreographer operates can be found in Section 2: Introducing Choreographer. Operational considerations for the successful deployment of Choreographer can be found in Section 3. The Testing & Evaluation (T&E) for Choreographer involved 3 phases: Pre-testing, Code Analysis, and Operational Testing. Pre-testing, described in Section 4, involved installing and configuring an instance of Choreographer and verifying it would operate as expected for a simple use case. Our findings were that it was simple and straightforward to prepare a system for a Choreographer installation as well as configure Choreographer to work in a representative environment. Code Analysis, described in Section 5, consisted of running a static code analyzer (HP Fortify) and conducting dynamic analysis tests using the Valgrind instrumentation framework. Choreographer performed well, such that only a few errors that might possibly be problematic in a given operating situation were identified. Operational Testing, described in Section 6, involved operating Choreographer in a representative environment created through EmulyticsTM . Depending upon the amount of server resources dedicated to Choreographer vis-á-vis the amount of client traffic handled, Choreographer had varying degrees of operational success. In an environment with a poorly resourced Choreographer server and as few as 50-100 clients, Choreographer failed to properly route traffic over half the time. Yet, with a well-resourced server, Choreographer handled over 1000 clients without missrouting. Choreographer

    Full Text Available Safe operation and industrial improvements are coming from the technology development and operational experience (OE feedback. A long life span for many industrial facilities makes OE very important. Proper assessment and understanding of OE remains a challenge because of organization system relations, complexity, and number of OE events acquired. One way to improve OE events understanding is to focus their investigation and analyze in detail the most important. The OE ranking method is developed to select the most important events based on the basic event parameters and the analytical hierarchy process applied at the level of event groups. This paper investigates further how uncertainty in the model affects ranking results. An analysis was performed on the set of the two databases from the 20 years of nuclear power plants in France and Germany. From all uncertainties the presented analysis selected ranking indexes as the most relevant for consideration. Here the presented analysis of uncertainty clearly shows that considering uncertainty is important for all results, especially for event groups ranked closely and next to the most important one. Together with the previously performed sensitivity analysis, uncertainty assessment provides additional insights and a better judgment of the event groups’ importance in further detailed investigation.

    This qualitative study reviews and analyzes quality improvement (QI) techniques in police departments as a background for assessing ways to introduce QI into public health departments. Police departments and public health departments have many elements in common. These findings provide some understanding of how public health departments can incorporate QI methods as well as learn about the potential barriers to implementing QI projects that are inherent in government agencies. The study consists of extensive interviews of informants from academic settings and police departments across the nation. The findings describe (1) the extent of QI diffusion into police departments, (2) barriers and enablers of QI diffusion in police departments, (3) a typology of QI diffusion, and (4) the metrics and incentives to promote QI in the absence of profit motives. Seven specific recommendations are made to promote the application and adoption of QI in public health: (1) implement QI as a comprehensive management approach, (2) top official involvement, (3) a broad focus on mission and vision, (4) lessons for overcoming barriers, (5) how to find resources, (6) how to integrate proven methods, and (7) how to build on existing capabilities.

    2017-01-01

    Full Text Available The purpose of this paper is to identify and analyse the current practices implemented in global universities for achieving sustainability throughout campus operations. This study adopted a web content analysis method where 30 international green universities’ websites have been thoroughly examined to identify common initiatives implemented to achieve sustainability through campus operations. The findings are ranked based on the implementation of these initiatives by participating universities. From the websites reviewed, as much as 31 initiatives have been identified as common initiatives frequently implemented by green universities to achieve sustainability in campus operations. It was found that the common initiatives frequently implemented by most of the universities include ‘Provide bin with clearly marked signs to increase the number of recycling items’, and ‘Generate electricity on campus by establishing power generation plants’ with 87% and 83% respectively. This paper fills the gap by presenting the investigation of sustainability initiatives from some of the major green universities internationally. It is suggested that higher education institutions, particularly Malaysian universities, initiate or manage their implementation of sustainable campus operation (SCO initiatives based on the findings of this research.

    1994-01-01

    A new approach for deducing the theory of fermion masses at the scale of grand unification is proposed. Combining SO(10) grand unification, family symmetries and supersymmetry with a systematic operator analysis, the minimal set of fermion mass operators consistent with low energy data is determined. Exploiting the full power of SO(10) to relate up, down and charged lepton mass matrices, we obtain predictions for 7 of the mass and mixing parameters. The assumptions upon which the operator search and resulting predictions are based are stressed, together with a discussion of how the predictions are affected by a relaxation of some of the assumptions.The masses of the heaviest generation, $m_t,m_b$ and $m_\\tau$, are generated from a single renormalizable Yukawa interaction, while the lighter masses and the mixing angles are generated by non-renormalizable operators of the grand unified theory. The hierarchy of masses and mixing angles is thereby related to the ratio of grand to Planck scales, $M_G / M_P$. An ex...

    A general observation is that both operational aspects and risk analysis cannot be adequately discussed without information presented in other sessions. Some overlap of conclusions and recommendations is therefore to be expected. Further, it was assumed that recommendations concerning improvements in some related topics were generated by other sessions and are not repeated here. These include: (1) Knowledge on degradation mechanisms (initiation, progression, and failure). (2) Modeling of degradation (initiation, progression, and failure). (3) Capabilities of NDE methods. (4) Preventive maintenance and repair. One should note here, however, that all of these directly affect both operational and risk aspects of affected plants. A list of conclusions and recommendations is based on available presentations and discussions addressing risk and operational experience. The authors aimed at reaching as broad a consensus as possible. It should be noted here that there is no strict delineation between operational and safety aspects of degradation of steam generator tubes. This is caused by different risk perceptions in different countries/societies. The conclusions and recommendations were divided into four broad groups: human reliability; leakage monitoring; risk impact; and consequence assessment.

  12. Operational modal analysis applied to the concert harp

    Operational modal analysis (OMA) methods are useful to extract modal parameters of operating systems. These methods seem to be particularly interesting to investigate the modal basis of string instruments during operation to avoid certain disadvantages due to conventional methods. However, the excitation in the case of string instruments is not optimal for OMA due to the presence of damped harmonic components and low noise in the disturbance signal. Therefore, the present study investigates the least-square complex exponential (LSCE) and the modified least-square complex exponential methods in the case of a string instrument to identify modal parameters of the instrument when it is played. The efficiency of the approach is experimentally demonstrated on a concert harp excited by some of its strings and the two methods are compared to a conventional modal analysis. The results show that OMA allows us to identify modes particularly present in the instrument's response with a good estimation especially if they are close to the excitation frequency with the modified LSCE method.

  13. Operational modal analysis modeling, Bayesian inference, uncertainty laws

    CERN Document Server

    Au, Siu-Kui

    2017-01-01

    This book presents operational modal analysis (OMA), employing a coherent and comprehensive Bayesian framework for modal identification and covering stochastic modeling, theoretical formulations, computational algorithms, and practical applications. Mathematical similarities and philosophical differences between Bayesian and classical statistical approaches to system identification are discussed, allowing their mathematical tools to be shared and their results correctly interpreted. Many chapters can be used as lecture notes for the general topic they cover beyond the OMA context. After an introductory chapter (1), Chapters 2–7 present the general theory of stochastic modeling and analysis of ambient vibrations. Readers are first introduced to the spectral analysis of deterministic time series (2) and structural dynamics (3), which do not require the use of probability concepts. The concepts and techniques in these chapters are subsequently extended to a probabilistic context in Chapter 4 (on stochastic pro...

    An important but understudied activity of the departments of internal medicine (IM) is the in-hospital consultations. We analyzed the requests for in-hospital consultation with IM and the potential differences between the consultations of medical and surgical departments. This was an 8-month observational prospective study that analyzed demographic variables related to the origin of the interconsultation, comorbidity, length of stay and hospital mortality, emergency, admission-consultation request delay, appropriateness (not appropriate if another department was consulted for the same reason or if the pathology behind the consultation was that of the requesting service) and, for patients who underwent surgery, whether it was requested before or after the surgery. During the study, 215 in-hospital consultations were conducted (27 consultations/month). The mean age of the patients was 69.8 years (women, 50%). Some 30.7% were requested by medical departments and 69.3% by surgical departments. Thirteen percent of the in-hospital consultations were duplicated. The department of IM was not the appropriate department consulted in 23.3% of cases (13.0% of the cases requested consultations for the same reason with another department; in 14.3% of the cases, the pathology was that of requesting department). More in-hospital consultations were conducted on Mondays and Fridays than on Thursdays (25.1% and 23.7% versus 15.3%, respectively; p=.03). The delay between admission and the request for interconsultation was of 12.6 days. Some 90.7% of the in-hospital consultations for patients undergoing surgery were requested after the intervention. There were no differences in the characteristics of the in-hospital consultations between the medical and surgical departments. In-hospital consultations directed at IM are frequently duplicate, are not well directed at the appropriate department and their urgency is incorrectly assessed. These characteristics are similar for the

    Models of organizational change-readiness have been developed, but little attention has been given to features of change-avid health-care institutions, and, to our knowledge, no attention has been given to features of change-avid respiratory therapy (RT) departments. We conducted an exploratory study to compare RT departments we deemed change-avid or non-change-avid, to identify differentiating characteristics. Our assessments regarding change-readiness and avidity were based on structured, in-person interviews of the technical directors and/or medical directors of 8 RT departments. Based on a priori criteria, 4 of the 8 RT departments were deemed change-avid, based on the presence of > or = 2 of the following 3 criteria: (1) uses a management information system, (2) uses a comprehensive RT protocol program, (3) uses noninvasive ventilation in > 20% of patients with exacerbation of chronic obstructive pulmonary disease. Our ratings of the departments were based on 2 scales: one from Integrated Organizational Development Inc, and the 8-stage change model of Kotter. The ratings of the 4 change-avid departments differed significantly from those of the 4 non-change-avid departments, on both the Integrated Organizational Development Inc scale and the Kotter scale. We identified 11 highly desired features of a change-avid RT department: a close working relationship between the medical director and the RT staff; a strong and supportive hospital "champion" for change; using data to define problems and measure the effectiveness of solutions; using redundant types of communication; recognizing resistance and minimizing obstacles to change; being willing to tackle tough issues; maintaining a culture of ongoing education; consistently rewarding change-avid behavior; fostering ownership for change and involving stakeholders; attending to RT leadership succession planning; and having and communicating a vision for the department. In this first exploratory study we found that

  19. Department of Defense Energy and Logistics: Implications of Historic and Future Cost, Risk, and Capability Analysis

    Tisa, Paul C.

    Every year the DoD spends billions satisfying its large petroleum demand. This spending is highly sensitive to uncontrollable and poorly understood market forces. Additionally, while some stakeholders may not prioritize its monetary cost and risk, energy is fundamentally coupled to other critical factors. Energy, operational capability, and logistics are heavily intertwined and dependent on uncertain security environment and technology futures. These components and their relationships are less understood. Without better characterization, future capabilities may be significantly limited by present-day acquisition decisions. One attempt to demonstrate these costs and risks to decision makers has been through a metric known as the Fully Burdened Cost of Energy (FBCE). FBCE is defined as the commodity price for fuel plus many of these hidden costs. The metric encouraged a valuable conversation and is still required by law. However, most FBCE development stopped before the lessons from that conversation were incorporated. Current implementation is easy to employ but creates little value. Properly characterizing the costs and risks of energy and putting them in a useful tradespace requires a new framework. This research aims to highlight energy's complex role in many aspects of military operations, the critical need to incorporate it in decisions, and a novel framework to do so. It is broken into five parts. The first describes the motivation behind FBCE, the limits of current implementation, and outlines a new framework that aids decisions. Respectively, the second, third, and fourth present a historic analysis of the connections between military capabilities and energy, analyze the recent evolution of this conversation within the DoD, and pull the historic analysis into a revised framework. The final part quantifies the potential impacts of deeply uncertain futures and technological development and introduces an expanded framework that brings capability, energy, and

    Violence runs into the fabric of society. In recent years, violence has been identified as an important health problem in industrialised societies. In the present study, conducted to analyze injury characteristics, 813 victims of interpersonal violence presenting to emergency department at a Government Medical College and Hospital from a major city in Central India were interviewed and examined over a period of one year. Central to the quantitative analysis of the data collected was the extraction of specific injury characteristics from the sample population. The group included 606 men and 207 females, most of them were resident of urban areas, aged between 11 and 30 years. Most of attacks occurred at nights, with minimal seasonal variation. Males were more commonly attacked outdoors by a single stranger male while females were mostly attacked indoors by spouse. Blunt trauma was more commonly seen in females as compared to males. Head neck and face region was the most preferred anatomical site by the assailants. Hard and blunt weapons were used more commonly at homes (184 of 269 incidents) than at streets (301 of 561 incidents). Sharp edged and pointed weapons were most commonly used at streets. Firearms were rarely used. Occurrence of physical assaults in this region more or less follows the pattern seen in other parts of the world with local and socio-cultural differences that need to be further delved into and considered during the planning and implementation of injury prevention programs.

    2014-05-01

    Full Text Available Introduction: National guidelines suggest that most skin abscesses do not require antibiotics, and that cellulitis antibiotics should target streptococci, not community-associated MRSA (CA-MRSA. The objective of this study is to describe antimicrobial treatment of skin infections in U.S. emergency departments (EDs and analyze potential quality measures. Methods: The National Hospital Ambulatory Medical Care Survey (NHAMCS is a 4-stage probability sample of all non-federal U.S. ED visits. In 2007 NHAMCS started recording whether incision and drainage was performed at ED visits. We conducted a retrospective analysis, pooling 2007-2010 data, identified skin infections using diagnostic codes, and identified abscesses by performance of incision and drainage. We generated national estimates and 95% confidence intervals using weighted analyses; quantified frequencies and proportions; and evaluated antibiotic prescribing practices. We evaluated 4 parameters that might serve as quality measures of antibiotic stewardship, and present 2 of them as potentially robust enough for implementation. Results: Of all ED visits, 3.2% (95% confidence interval 3.1-3.4% were for skin infection, and 2.7% (2.6-2.9% were first visits for skin infection, with no increase over time (p=0.80. However, anti-CA-MRSA antibiotic use increased, from 61% (56-66% to 74% (71-78% of antibiotic regimens (p<0.001. Twenty-two percent of visits were for abscess, with a non-significant increase (p=0.06. Potential quality measures: Among discharged abscess patients, 87% were prescribed antibiotics (84-90%, overuse. Among antibiotic regimens for abscess patients, 84% included anti-CA-MRSA agents (81-89%, underuse. Conclusion: From 2007-2010, use of anti-CA-MRSA agents for skin infections increased significantly, despite stable visit frequencies. Antibiotics were over-used for discharged abscess cases, and CA-MRSA-active antibiotics were underused among regimens when antibiotics were used for

    The objective of this study was to analyze demographic and event characteristics of patients presenting to the Emergency Department (ED) for evaluation after sexual assault, using a Sexual Assault Nurse Examiner standardized database. Data were prospectively collected as part of the Sexual Assault Nurse Examiner program at an urban teaching hospital. This study reviewed all ED patient records with a complaint of sexual assault between January 1, 2000 and December 31, 2004. Data were collected on 1172 patients; 92.6% were women, with a mean age of 27 years. The sample was 59.1% black, 38.6% white, and 2.3% "Other." Black victims of sexual assault were significantly more likely to be young (25 years or less) than Whites. Over half (54%) reported involvement of drugs or alcohol during the event. Fifty-three percent knew their assailant(s), and black and young patients were significantly more likely to know the perpetrator(s). Threats of force were common (72.4% of sample), and multiple assailants were uncommon (18.1% of sample). Physical evidence of trauma was present in more than half (51.7%), with increased rates among Whites and older persons. Multivariate analysis showed that race, age, threats, and substance use during the event were independent risk factors for evident trauma on physical examination. Survivors of sexual assault who present to the ED are overwhelmingly female, relatively young, often know the perpetrator of the event, and are likely to be threatened and show signs of physical trauma. Differences between patients according to demographic and event characteristics may have important implications for ED management and treatment plans.

    High expectations for new technologies coexist with wide variability in the actual adoption and impact of information technology (IT) projects in clinical settings, and the frequent failure to incorporate otherwise "successful" projects into routine practice. This paper draws on actor-network theory to present an in-depth, sociotechnical analysis of one such project--a computer kiosk designed to diagnose and expedite treatment of urinary tract infections (UTI) in adult women. Research at a hospital urgent care clinic demonstrated the kiosk program's effectiveness at diagnosing UTI and reducing patient wait times, and the kiosk was subsequently adopted by the clinic for routine patient care. However, a study promoting the adoption of the device at emergency departments (ED) was characterized by persistent staff resistance and lower-than-expected patient eligibility for kiosk-assisted care. The device was ultimately abandoned at all but one of the new sites. Observations and interviews with ED staff and the design/research team were conducted at four California EDs between April and July 2011 and point to conflicting understandings of evidence for the device's usefulness and reasons for its (non)adoption. The kiosk program's designers had attempted to "rationalize" medical work by embedding a formal representation of triage practices in the kiosk's software. However, the kiosk's "network" failed to stabilize as it encountered different patient populations, institutional politics, and the complex, pragmatic aspects of ED work at each site. The results of this evaluation challenge the persistent myth that a priori qualities and meanings inhere in technology regardless of context. The design and deployment of new IT projects in complex medical settings would benefit from empirically informed understandings of, and responses to, the contingent properties of human-technology relations.

    Full Text Available Introduction: Patients with sickle cell disease (SCD often seek care in emergency departments (EDs for severe pain. However, there is evidence that they experience inaccurate assessment, suboptimal care, and inadequate follow-up referrals. The aim of this project was to 1 explore the feasibility of applying a failure modes, effects and criticality analysis (FMECA in two EDs examining four processes of care (triage, analgesic management, high risk/high users, and referrals made for patients with SCD, and 2 report the failures of these care processes in each ED. Methods: A FMECA was conducted of ED SCD patient care at two hospitals. A multidisciplinary group examined each step of four processes. Providers identified failures in each step, and then characterized the frequency, impact, and safeguards, resulting in risk categorization. Results: Many “high risk” failures existed in both institutions, including a lack of recognition of high-risk or high-user patients and a lack of emphasis on psychosocial referrals. Specific to SCD analgesic management, one setting inconsistently used existing analgesic policies, while the other setting did not have such policies. Conclusion: FMECA facilitated the identification of failures of ED SCD care and has guided quality improvement activities. Interventions can focus on improvements in these specific areas targeting improvements in the delivery and organization of ED SCD care. Improvements should correspond with the forthcoming National Heart, Lung and Blood-sponsored guidelines for treatment of patients with sickle cell disease. [West J Emerg Med. 2014;15(4:446–458.

    High quality data is fundamental to using key performance indicators (KPIs) for performance monitoring. However, the resources required to collect high quality data are often significant and should usually be targeted at high priority areas. As part of a study of 11 emergency department (ED) KPIs in Ireland, the primary objective of this study was to estimate the relative cost of collecting the additional minimum data set (MDS) elements for those 11 KPIs. An economic cost analysis focused on 12 EDs in the Republic of Ireland. The resource use data were obtained using two separate focus group interviews. The number of available MDS elements was obtained from a sample of 100 patient records per KPI per participating ED. Unit costs for all resource use were taken at the midpoint of the relevant staff salary scales. An ED would need to spend an estimated additional &OV0556;3561 per month on average to capture all the MDS elements relevant to the 11 KPIs investigated. The additional cost ranges from 14.8 to 39.2%; this range is 13.9-32.3% for small EDs, whereas the range for medium EDs is 11.7-40%. Regional EDs have a higher additional estimated cost to capture all the relevant MDS elements (&OV0556;3907), compared with urban EDs (&OV0556;3353). The additional cost of data collection, contingent on that already collected, required to capture all the relevant MDS elements for the KPIs examined, ranges from 14.8 to 39.2% per KPI, with variation identified between regional and urban hospitals.

This study used a summative qualitative content analysis approach involving six steps: (1) a comprehensive search; (2) two-stage reading and screening process to identify first-hand, health-related records; (3) qualitative and quantitative data analysis using MAXQDA, a software program; (4) a word cloud to illustrate word frequencies and interrelationships; (5) coding of individual themes and validation of the coding scheme; and (6) identification of relationships in the data and overarching lessons-learned. The individual codes with the most number of text segments coded included: planning, personnel, interorganizational coordination, communication/information sharing, and resources/supplies. When compared to the Department of Defense's (DoD's) evolving GHE principles and capabilities, the SOLLIMS coding scheme appeared to align well with the list of GHE capabilities developed by the Department of Defense Global Health Working Group. The results of this study will inform practitioners of global health and encourage additional qualitative analysis of other lessons-learned databases.

    1992-08-01

    This report describes the gamma-ray analysis program VAXGAP, which has continually evolved at the Idaho National Engineering Laboratory over a period of several years. It is an integrated suite of computer programs for performing analyses of pulse-height spectra from high-resolution gamma-ray spectrometers and assorted support functions. VAXGAP programs operate on Digital Equipment Corporation (DEC) VAX computers running the VMS operating system, and were written in VAX FORTRAN and DEC Digital Command Language (DCL). These programs make use of DEC GKS and ReGIS for graphical output on standard terminals and printers, and DEC windows for graphics on workstations and terminals that support the X Window System protocol. This report addresses the use of VAXGAP for data acquisition and control, energy scale calibration, and real-time analyses of background and sample pulse-height spectra. Also addressed are the creation and use efficiency tables and isotope libraries, manipulation of spectrum files and their contents, and graphical display of on-going acquisitions, saved spectra, and mathematical fits to spectral peaks.

    Demonstration of viral clearance is a critical step in assuring the safety of biotechnology products. We generated a viral clearance database that contains product information, unit operation process parameters, and viral clearance data from monoclonal antibody and antibody-related regulatory submissions to FDA. Here we present a broad overview of the database and resulting analyses. We report that the diversity of model viruses tested expands as products transition to late-phase. We also present averages and ranges of viral clearance results by Protein A and ion exchange chromatography steps, low pH chemical inactivation, and virus filtration, focusing on retro- and parvoviruses. For most unit operations, an average log reduction value (LRV, a measure of clearance power) for retrovirus of >4 log(10) were measured. Cases where clearance data fell outside of the anticipated range (i.e., outliers) were rationally explained. Lastly, a historical analysis did not find evidence of any improvement trend in viral clearance over time. The data collectively suggest that many unit operations in general can reliably clear viruses.

  18. Statistical Scalability Analysis of Communication Operations in Distributed Applications

    2001-02-27

    Current trends in high performance computing suggest that users will soon have widespread access to clusters of multiprocessors with hundreds, if not thousands, of processors. This unprecedented degree of parallelism will undoubtedly expose scalability limitations in existing applications, where scalability is the ability of a parallel algorithm on a parallel architecture to effectively utilize an increasing number of processors. Users will need precise and automated techniques for detecting the cause of limited scalability. This paper addresses this dilemma. First, we argue that users face numerous challenges in understanding application scalability: managing substantial amounts of experiment data, extracting useful trends from this data, and reconciling performance information with their application's design. Second, we propose a solution to automate this data analysis problem by applying fundamental statistical techniques to scalability experiment data. Finally, we evaluate our operational prototype on several applications, and show that statistical techniques offer an effective strategy for assessing application scalability. In particular, we find that non-parametric correlation of the number of tasks to the ratio of the time for individual communication operations to overall communication time provides a reliable measure for identifying communication operations that scale poorly.

    1982-02-12

    The Lawrence Livermore National Laboratory is involved in many facets of research ranging from nuclear weapons research to advanced Biomedical studies. Approximately 80% of all programs at LLNL generate hazardous waste in one form or another. Aside from producing waste from industrial type operations (oils, solvents, bottom sludges, etc.) many unique and toxic wastes are generated such as phosgene, dioxin (TCDD), radioactive wastes and high explosives. One key to any successful waste management program must address the following: proper identification of the waste, safe handling procedures and proper storage containers and areas. This section of the Waste Management Plan will address methodologies used for the Analysis of Hazardous Waste. In addition to the wastes defined in 40 CFR 261, LLNL and Site 300 also generate radioactive waste not specifically covered by RCRA. However, for completeness, the Waste Analysis Plan will address all hazardous waste.

  3. Model validity and frequency band selection in operational modal analysis

    Au, Siu-Kui

    2016-12-01

    Experimental modal analysis aims at identifying the modal properties (e.g., natural frequencies, damping ratios, mode shapes) of a structure using vibration measurements. Two basic questions are encountered when operating in the frequency domain: Is there a mode near a particular frequency? If so, how much spectral data near the frequency can be included for modal identification without incurring significant modeling error? For data with high signal-to-noise (s/n) ratios these questions can be addressed using empirical tools such as singular value spectrum. Otherwise they are generally open and can be challenging, e.g., for modes with low s/n ratios or close modes. In this work these questions are addressed using a Bayesian approach. The focus is on operational modal analysis, i.e., with 'output-only' ambient data, where identification uncertainty and modeling error can be significant and their control is most demanding. The approach leads to 'evidence ratios' quantifying the relative plausibility of competing sets of modeling assumptions. The latter involves modeling the 'what-if-not' situation, which is non-trivial but is resolved by systematic consideration of alternative models and using maximum entropy principle. Synthetic and field data are considered to investigate the behavior of evidence ratios and how they should be interpreted in practical applications.

    Energy and exergy studies were conducted in an orange juice manufacturing industry in Nigeria to determine the energy consumption pattern and methods of energy optimization in the company. An adaptation of the process analysis method of energy accounting was used to evaluate the energy requirement for each of the eight defined unit operations. The types of energy used in the manufacturing of orange juice were electrical, steam and manual with the respective proportions of 18.51%, 80.91% and 0.58% of the total energy. It was estimated that an average energy intensity of 1.12 MJ/kg was required for the manufacturing of orange juice. The most energy intensive operation was identified as the pasteurizer followed by packaging unit with energy intensities of 0.932 and 0.119 MJ/kg, respectively. The exergy analysis revealed that the pasteurizer was responsible for most of the inefficiency (over 90%) followed by packaging (6.60%). It was suggested that the capacity of the pasteurizer be increased to reduce the level of inefficiency of the plant. The suggestion has been limited to equipment modification rather than process alteration, which constitutes additional investment cost and may not be economical from an energy savings perspective.

    2015-04-01

    Full Text Available Trillions of liters of wastewater from oil and gas extraction are generated annually in the US. The contribution from unconventional drilling operations (UDO, such as hydraulic fracturing, to this volume will likely continue to increase in the foreseeable future. The chemical content of wastewater from UDO varies with region, operator, and elapsed time after production begins. Detailed chemical analyses may be used to determine its content, select appropriate treatment options, and identify its source in cases of environmental contamination. In this study, one wastewater sample each from direct effluent, a disposal well, and a waste pit, all in West Texas, were analyzed by gas chromatography-mass spectrometry, inductively coupled plasma-optical emission spectroscopy, high performance liquid chromatography-high resolution mass spectrometry, high performance ion chromatography, total organic carbon/total nitrogen analysis, and pH and conductivity analysis. Several compounds known to compose hydraulic fracturing fluid were detected among two of the wastewater samples including 2-butoxyethanol, alkyl amines, and cocamide diethanolamines, toluene, and o-xylene. Due both to its quantity and quality, proper management of wastewater from UDO will be essential.

  6. Methodological frontier in operational analysis for roundabouts: a review

    Orazio Giuffre'

    2016-11-01

    Full Text Available Several studies and researches have shown that modern roundabouts are safe and effective as engineering countermeasures for traffic calming, and they are now widely used worldwide. The increasing use of roundabouts and, more recently, turbo and flower roundabouts, has induced a great variety of experiences in the field of intersection design, traffic safety and capacity modelling. As for unsignalized intersections which represent the starting point to extend knowledge about the operational analysis to roundabouts, the general situation in capacity estimation is still characterized by the discussion between gap acceptance models and empirical regression models. However, capacity modelling must contain both the analytical construction and then solution of the model, and the implementation of driver behavior. Thus, issues on a realistic modelling of driver behavior by the parameters that are included into the models are always of interest for practioners and analysts in transportation and road infrastructure engineering. Based on these considerations, this paper presents a literature review about the key methodological issues in the operational analysis of modern roundabouts. Focus is made on the aspects associated with the gap acceptance behavior, the derivation of the analytical-based models and the calculation of parameters included into the capacity equations, as well as steady state and non-steady state conditions and uncertainty in entry capacity estimation. At last, insights on future developments of the research in this field of investigation will be also outlined.

    Monte is a software set designed for use in mission design and spacecraft navigation operations. The system can process measurement data, design optimal trajectories and maneuvers, and do orbit determination, all in one application. For the first time, a single software set can be used for mission design and navigation operations. This eliminates problems due to different models and fidelities used in legacy mission design and navigation software. The unique features of Monte 040 include a blowdown thruster model for GRAIL (Gravity Recovery and Interior Laboratory) with associated pressure models, as well as an updated, optimalsearch capability (COSMIC) that facilitated mission design for ARTEMIS. Existing legacy software lacked the capabilities necessary for these two missions. There is also a mean orbital element propagator and an osculating to mean element converter that allows long-term orbital stability analysis for the first time in compiled code. The optimized trajectory search tool COSMIC allows users to place constraints and controls on their searches without any restrictions. Constraints may be user-defined and depend on trajectory information either forward or backwards in time. In addition, a long-term orbit stability analysis tool (morbiter) existed previously as a set of scripts on top of Monte. Monte is becoming the primary tool for navigation operations, a core competency at JPL. The mission design capabilities in Monte are becoming mature enough for use in project proposals as well as post-phase A mission design. Monte has three distinct advantages over existing software. First, it is being developed in a modern paradigm: object- oriented C++ and Python. Second, the software has been developed as a toolkit, which allows users to customize their own applications and allows the development team to implement requirements quickly, efficiently, and with minimal bugs. Finally, the software is managed in accordance with the CMMI (Capability Maturity Model

  8. Applications of human error analysis to aviation and space operations

    Nelson, W.R.

    1998-07-01

    For the past several years at the Idaho National Engineering and Environmental Laboratory (INEEL) we have been working to apply methods of human error analysis to the design of complex systems. We have focused on adapting human reliability analysis (HRA) methods that were developed for Probabilistic Safety Assessment (PSA) for application to system design. We are developing methods so that human errors can be systematically identified during system design, the potential consequences of each error can be assessed, and potential corrective actions (e.g. changes to system design or procedures) can be identified. These applications lead to different requirements when compared with HR.As performed as part of a PSA. For example, because the analysis will begin early during the design stage, the methods must be usable when only partial design information is available. In addition, the ability to perform numerous ''what if'' analyses to identify and compare multiple design alternatives is essential. Finally, since the goals of such human error analyses focus on proactive design changes rather than the estimate of failure probabilities for PRA, there is more emphasis on qualitative evaluations of error relationships and causal factors than on quantitative estimates of error frequency. The primary vehicle we have used to develop and apply these methods has been a series of projects sponsored by the National Aeronautics and Space Administration (NASA) to apply human error analysis to aviation operations. The first NASA-sponsored project had the goal to evaluate human errors caused by advanced cockpit automation. Our next aviation project focused on the development of methods and tools to apply human error analysis to the design of commercial aircraft. This project was performed by a consortium comprised of INEEL, NASA, and Boeing Commercial Airplane Group. The focus of the project was aircraft design and procedures that could lead to human errors during

    Specialty emergency departments (EDs) provide a unique mechanism of health care delivery, but the value that they add to the medical system is not known. Evaluation of patient preferences to determine value can have a direct impact on resource allocation and direct-to-specialist care. To assess the feasibility of contingent valuation (CV) methodology using a willingness-to-pay (WTP) survey to evaluate specialty emergency services, in the context of an ophthalmology- and otolaryngology-specific ED. Contingent valuation analysis of a standalone otolaryngology and ophthalmology ED. Participants were English-speaking adults presenting to a dedicated otolaryngology and ophthalmology ED. The WTP questions were assessed using a payment card format, with reference to an alternative modality of treatment (ie, general ED), and were analyzed with multivariate regression. Validated WTP survey administered from October 14, 2014, through October 1, 2015. Sociodemographic data, level of distress, referral data, income, and WTP. A total of 327 of 423 (77.3%) ED patients responded to the WTP survey, with 116 ophthalmology and 211 otolaryngology patients included (52.3% female; mean [range] age, 46 [18-90] years). The most common reason for seeking care at this facility was a reputation for specialty care for both ear, nose, and throat (80 [37.9%]) and ophthalmology (43 [37.1%]). Mean WTP for specialty-specific ED services was $377 for ophthalmology patients, and $321 for otolaryngology patients ($340 overall; 95% CI, $294 to $386), without significant difference between groups (absolute difference, $56; 95% CI, $-156 to $43). Self-reported level of distress was higher among ear, nose, and throat vs ophthalmology patients (absolute difference, 0.47 on a Likert scale of 1-7; 95% CI, 0.10 to 0.84). Neither level of distress, income, nor demographic characteristics influenced WTP, but patients with higher estimates of total visit cost were more likely to have higher WTP (β coefficient

  14. Composite Operator Method Analysis of the Underdoped Cuprates Puzzle

    Directory of Open Access Journals (Sweden)

    Adolfo Avella

    2014-01-01

    Full Text Available The microscopical analysis of the unconventional and puzzling physics of the underdoped cuprates, as carried out lately by means of the composite operator method (COM applied to the 2D Hubbard model, is reviewed and systematized. The 2D Hubbard model has been adopted as it has been considered the minimal model capable of describing the most peculiar features of cuprates held responsible for their anomalous behavior. COM is designed to endorse, since its foundation, the systematic emergence in any SCS of new elementary excitations described by composite operators obeying noncanonical algebras. In this case (underdoped cuprates—2D Hubbard model, the residual interactions—beyond a 2-pole approximation—between the new elementary electronic excitations, dictated by the strong local Coulomb repulsion and well described by the two Hubbard composite operators, have been treated within the noncrossing approximation. Given this recipe and exploiting the few unknowns to enforce the Pauli principle content in the solution, it is possible to qualitatively describe some of the anomalous features of high-Tc cuprate superconductors such as large versus small Fermi surface dichotomy, Fermi surface deconstruction (appearance of Fermi arcs, nodal versus antinodal physics, pseudogap(s, and kinks in the electronic dispersion. The resulting scenario envisages a smooth crossover between an ordinary weakly interacting metal sustaining weak, short-range antiferromagnetic correlations in the overdoped regime to an unconventional poor metal characterized by very strong, long-but-finite-range antiferromagnetic correlations leading to momentum-selective non-Fermi liquid features as well as to the opening of a pseudogap and to the striking differences between the nodal and the antinodal dynamics in the underdoped regime.

    Airline alliances are dominating the current air transport industry with the largest carriers of the world belonging to one of the four alliance groupings - "Wings", Star Alliance, one world, SkyTeam - which represent 56% of world Revenue Passenger Kilometers. Although much research has been carried out to evaluate the impact of alliance membership on performance of airlines, it would be of interest to ascertain the degree of impact perceived by participating airlines in alliances. It is the purpose of this paper to gather the opinion of all the airlines, belonging to the four global alliance groupings on the impact alliances have had on their traffic and on their performance in general To achieve this, a comprehensive survey of the alliance management departments of airlines participating in the four global strategic alliances was carried out. With this framework the survey has examined which type of cooperation among carriers (FFP, Code Share, Strategic Alliance without antitrust immunity, Strategic Alliance with antitrust immunity) has produced the most positive impact on traffic and which type of route (short haul, long haul, hub-hub, hub-non hub, non hub-non hub) has been mostly affected. In addition, the respondent airlines quantified the effect alliances have had on specific areas of their operation, such as load factors, traffic, costs, revenue and fares. Their responses have been analysed under each global alliances grouping, under airline and under geographic region to establish which group, type of carrier and geographic region has benefited most. The results show that each of the four global alliances groupings has experienced different results according to the type of collaboration agreed amongst their member airlines.

    Brito, Mario Paulo; Griffiths, Gwyn; Challenor, Peter

    2010-12-01

    Autonomous underwater vehicles (AUVs) are used increasingly to explore hazardous marine environments. Risk assessment for such complex systems is based on subjective judgment and expert knowledge as much as on hard statistics. Here, we describe the use of a risk management process tailored to AUV operations, the implementation of which requires the elicitation of expert judgment. We conducted a formal judgment elicitation process where eight world experts in AUV design and operation were asked to assign a probability of AUV loss given the emergence of each fault or incident from the vehicle's life history of 63 faults and incidents. After discussing methods of aggregation and analysis, we show how the aggregated risk estimates obtained from the expert judgments were used to create a risk model. To estimate AUV survival with mission distance, we adopted a statistical survival function based on the nonparametric Kaplan-Meier estimator. We present theoretical formulations for the estimator, its variance, and confidence limits. We also present a numerical example where the approach is applied to estimate the probability that the Autosub3 AUV would survive a set of missions under Pine Island Glacier, Antarctica in January-March 2009.

    2016-01-01

    A new interval arithmetic method is proposed to solve interval functions with correlated intervals through which the overestimation problem existing in interval analy-sis could be significantly alleviated. The correlation between interval parameters is defined by the multidimensional par-allelepiped model which is convenient to describe the correlative and independent interval variables in a unified framework. The original interval variables with correlation are transformed into the standard space without correlation, and then the relationship between the original variables and the standard interval variables is obtained. The expressions of four basic interval arithmetic operations, namely addi-tion, subtraction, multiplication, and division, are given in the standard space. Finally, several numerical examples and a two-step bar are used to demonstrate the effectiveness of the proposed method.

    An analysis was performed of the operations of hydropower systems, with emphasis on water resource management, to determine how aerospace derived information system technologies can effectively increase energy output. Better utilization of water resources was sought through improved reservoir inflow forecasting based on use of hydrometeorologic information systems with new or improved sensors, satellite data relay systems, and use of advanced scheduling techniques for water release. Specific mechanisms for increased energy output were determined, principally the use of more timely and accurate short term (0-7 days) inflow information to reduce spillage caused by unanticipated dynamic high inflow events. The hydrometeorologic models used in predicting inflows were examined in detail to determine the sensitivity of inflow prediction accuracy to the many variables employed in the models, and the results were used to establish information system requirements. Sensor and data handling system capabilities were reviewed and compared to the requirements, and an improved information system concept was outlined.

    The Analysis of Operations Management Strategies oflKEA IKEA, as a multinational corporation, is a world famous home furniture company whose vision is "To provide better life for everYone". IKEA was founded in 1943 by Ingvar Karaprad, a young entrepreneur from Elmtaryd, Sweden. Initially Kamprad sold a wide range of products such as pencils, nylon stockings, wallets and watches via mail order. In 1948 Ikea started offering furniture for sale, and three years later the first edition of the Ikea catalogue was released. The first IKEA store opened in 1958 in Almhult, Sweden. From i958, the company expanded fast, opening its first store abroad in 1963. Since then, IKEA has expanded to 38 countries and 301 stores:

    The higher education system in Indonesia can be considered not only as an important source of developing knowledge in the country, but also could create positive living conditions for the country. Therefore it is not surprising that enrollments in higher education continue to expand. However, the implication of this situation, the Indonesian government is necessarily to support more funds. In the interest of accountability, it is essential to measure the efficiency for this higher institution. Data envelopment analysis (DEA) is a method to evaluate the technical efficiency of production units which have multiple input and output. The higher learning institution considered in this paper is Malikussaleh University located in Lhokseumawe, a city in Aceh province of Indonesia. This paper develops a method to evaluate efficiency for all departments in Malikussaleh University using DEA with bounded output. Accordingly, we present some important differences in efficiency of those departments. Finally we discuss the effort should be done by these departments in order to become efficient.

    In a ship or floating structure operation the agents that contribute to the systems behaviour are not only those derived from fluid-structure interaction, but also the ones linked to mooring-control line set-up evolution and human interaction. Therefore, the analysis of such systems is affected by boundary conditions that change during a complete operation. Frequently, monitoring techniques in laboratory (model) and field (prototype) are based in different instrumental techniques adding difficulty to data comparison and, in some cases, inducing precision and repeatability errors. For this reason, the main aim of this study is to develop the methods and tools to achieve a deep knowledge of those floating systems and obtain capabilities to optimize their operationally thresholds. This abstract presents a methodology and an instrumental system applicable both in field and laboratory: SRECMOCOS Project (Small scale REal-time Caisson MOnitoring and COntrol System). SRECMOCOS compiles three modules. For the monitoring and control of the structure it has been developed a synchronized open and modular microcontroller-based electronic system that comprises sensors, to monitor agents and reactions, and actuators to perform pertinent actions after processing the sensors' data. A secondary objective has been to design and implement a global scaled simulator (1:22), at the 3D basin of The Harbour Research Lab at Technical University of Madrid, in which climatic agents and those derived from the rig/maneuvering setup and the structural design were included. The particular case of Campamento's drydock, in Algeciras Bay (Spain), has been used to apply and validate the methodology. SRECMOCOS Project conjugates control, monitoring and wireless communication systems in a real time basis, offering the possibility to register and simulate all the parameters involved in port operations. This approach offers a step forward into a monitoring strategy to be included in monitoring

    This paper examined the tendency of strategic decision makers in public health to allow their strategic planning process to degenerate into short-term, operational management. The temptation is great in light of pressing current problems. However, the danger of not thinking strategically about the future and of failing to attempt to position the organization in such a way as to take advantage of its strengths and minimize the adverse consequences of its weaknesses can be catastrophic. An attempt is made to illustrate how one state department of public health attempted to ensure that strategic thinking remained a part of its strategic planning process. The process was built around the energizing of the expertise present in the department and the mobilization of resources under the direction of the State Health Officer. The process is ongoing and is constantly fine tuned. However, the procedure utilized can be adapted easily to the unique circumstances facing most public health organizations.

    This study investigated if results of haematology and biochemistry laboratory tests, carried out at the point of care in our Emergency Department, are checked by the clinician who ordered the test, mitigating the requirement to check printed reports later. Five hundred and nineteen (519) laboratory reports were examined for significant abnormal results and documentation in clinical notes. Thirty percent (30%, n = 158) of these met the inclusion criteria for \\'significantly abnormal\\' laboratory results. Of the 158 significantly abnormal results, 34.8% (n = 55) were not documented in the ED clinical case notes. No patient was discharged inappropriately. Our study suggests it is safe to stop routinely rechecking printed biochemistry and haematology laboratory reports in our department.

    Whether operative treatment for complex proximal humeral fractures (CPHFs) has a greater benefit over non-operative treatment remains controversial. There is no consensus on the optimal treatment in elderly patients with CPHFs. This updated meta-analysis of randomized controlled trials (RCTs) aims to investigate whether operative treatment is superior to non-operative treatment in CPHFs. The authors searched RCTs in the electronic databases (Cochrane Central Register of Controlled Trials, PubMed, EMBASE, Medline, Embase, Springer Link, Web of Knowledge, OVID and Google Scholar) from their establishment to July 2015. Researches on operative and non-operative treatment for CPHFs were selected in this meta-analysis. The quality of all studies was assessed and effective data was pooled for this meta-analysis. Outcome measurements were functional status include constant scores (CS scores) and disabilities of the arm, shoulder and hand scores (DASH scores), total complication rates and healthy-related quality of life. The meta-analysis was performed with software revman 5.3. Nine articles with a total 518 patients (average age 70.93) met inclusion criteria. Patients were followed up for at least 1 year in all the studies. No statistical differences were found between operative and non-operative treatment in CS scores at 12 mo (months) [MD 1.06 95 % CI (-3.51, 5.62)] and 24 mo [MD -0.61 95 % CI (-5.87, 4.65)]. There are also no statistical differences between operative and non-operative treatment in DASH scores at 12 mo [MD -4.51 95 % CI (-13.49, 4.47)] and 24 mo [MD -7.43 95 % CI (-16.14, 1.27)]. Statistical differences were found between operative and non-operative treatment in total complication rates [RR 1.55, 95 % CI (1.24, 1.94)]. Statistical differences in EQ-5D at 24 mo [MD 0.15, 95 % CI (0.05, 0.24)] were found between operative and non-operative treatment but no statistical differences were found in ED-5D at 12 mo [MD 0.08, 95 % CI (-0.01, 0.17)], 15D at

    Fukushima Daiichi nuclear accident resulted in the core damage in three reactors and the release of considerable amount of radioactive material to the environment, not to mention significant social impact and anti-nuclear atmosphere all around the world. This paper provides a review of the findings related to shift operators' operation of the isolation condenser in Unit 1 to examine shift operators' response to the situation. Based on the review of the findings, a situation assessment model was developed to analyze shift operators' understanding on whether core cooling was successfully performed in Unit 1 through the operation of isolation condenser. It was found that lack of information could be one of the main causes for the failure in core cooling by the IC in Unit 1. It is also recommended that the differences in the mathematical model for the situation assessment and that of the real operator need to be further investigated.

    Full Text Available This paper describes the results of a model updating study conducted on a historical aqueduct, called Veziragasi, in Turkey. The output-only modal identification results obtained from ambient vibration measurements of the structure were used to update a finite element model of the structure. For the purposes of developing a solid model of the structure, the dimensions of the structure, defects, and material degradations in the structure were determined in detail by making a measurement survey. For evaluation of the material properties of the structure, nondestructive and destructive testing methods were applied. The modal analysis of the structure was calculated by FEM. Then, a nondestructive dynamic test as well as operational modal analysis was carried out and dynamic properties were extracted. The natural frequencies and corresponding mode shapes were determined from both theoretical and experimental modal analyses and compared with each other. A good harmony was attained between mode shapes, but there were some differences between natural frequencies. The sources of the differences were introduced and the FEM model was updated by changing material parameters and boundary conditions. Finally, the real analytical model of the aqueduct was put forward and the results were discussed.

    This paper is devoted to wavelet analysis on adele ring $\\bA$ and the theory of pseudo-differential operators. We develop the technique which gives the possibility to generalize finite-dimensional results of wavelet analysis to the case of adeles $\\bA$ by using infinite tensor products of Hilbert spaces. The adele ring is roughly speaking a subring of the direct product of all possible ($p$-adic and Archimedean) completions $\\bQ_p$ of the field of rational numbers $\\bQ$ with some conditions at infinity. Using our technique, we prove that $L^2(\\bA)=\\otimes_{e,p\\in\\{\\infty,2,3,5,...}}L^2({\\bQ}_{p})$ is the infinite tensor product of the spaces $L^2({\\bQ}_{p})$ with a stabilization $e=(e_p)_p$, where $e_p(x)=\\Omega(|x|_p)\\in L^2({\\bQ}_{p})$, and $\\Omega$ is a characteristic function of the unit interval $[0,\\,1]$, $\\bQ_p$ is the field of $p$-adic numbers, $p=2,3,5,...$; $\\bQ_\\infty=\\bR$. This description allows us to construct an infinite family of Haar wavelet bases on $L^2(\\bA)$ which can be obtained by shifts...

    Full Text Available In this paper, we describe an Operational Modal Analysis (OMA of the Bridge over the Tocantins River, a composite road-rail bridge located in the city of Marabá, state of Pará, northern Brazil. The bridge is part of the Carajás Railway, which is used by VALE Company to transport iron ore from “Serra dos Carajás”, the largest mineral reserve of the planet. The bridge has a length of 2310m, being the second longest road-rail bridge in Brazil. The study focused on the bridge central span (with 77 m of length and two adjacent spans (with 44 m of length. We employed Piezo-electric accelerometers to measure the dynamic response of the bridge under ambient excitation, which consisted of the passage of loaded and unloaded trains, road traffic, wind and river current. For modal identification, to avoid the influence of the train mass over the bridge system, we only considered acceleration signals of road traffic and signals corresponding to intervals after the passage of loaded trains, i.e., the study disregarded the intervals during which the trains were over the monitored spans. We obtained modal parameters through two identification methods: one in the time domain and other in the frequency domain. We also performed a comparative analysis between the experimental modal parameters, and the numerical results obtained with a finite element model provided by a third-part company.

    A sampling program was undertaken to determine the operating parameters which affected air pollution emission from gray iron foundry cupolas. The experimental design utilized the analysis of variance routine. Four independent variables were selected for examination on the basis of previous work reported in the literature. These were: (1) blast rate; (2) iron-coke ratio; (3) blast temperature; and (4) cupola size. The last variable was chosen since it most directly affects melt rate. Emissions from cupolas for which concern has been expressed are particle matter and carbon monoxide. The dependent variables were, therefore, particle loading, particle size distribution, and carbon monoxide concentration. Seven production foundries were visited and samples taken under conditions prescribed by the experimental plan. The data obtained from these tests were analyzed using the analysis of variance and other statistical techniques where applicable. The results indicated that blast rate, blast temperature, and cupola size affected particle emissions and the latter two also affected the particle size distribution. The particle size information was also unique in that it showed a consistent particle size distribution at all seven foundaries with a sizable fraction of the particles less than 1.0 micrometers in diameter.

    We give a methodology-oriented perspective on directional image analysis and rotation-invariant processing. We review the state of the art in the field and make connections with recent mathematical developments in functional analysis and wavelet theory. We unify our perspective within a common framework using operators. The intent is to provide image-processing methods that can be deployed in algorithms that analyze biomedical images with improved rotation invariance and high directional sensitivity. We start our survey with classical methods such as directional-gradient and the structure tensor. Then, we discuss how these methods can be improved with respect to robustness, invariance to geometric transformations (with a particular interest in scaling), and computation cost. To address robustness against noise, we move forward to higher degrees of directional selectivity and discuss Hessian-based detection schemes. To present multiscale approaches, we explain the differences between Fourier filters, directional wavelets, curvelets, and shearlets. To reduce the computational cost, we address the problem of matching directional patterns by proposing steerable filters, where one might perform arbitrary rotations and optimizations without discretizing the orientation. We define the property of steerability and give an introduction to the design of steerable filters. We cover the spectrum from simple steerable filters through pyramid schemes up to steerable wavelets. We also present illustrations on the design of steerable wavelets and their application to pattern recognition.

Failure rate was lower after an operation with stoma without anastomosis (6 of 43, 14%) than after an operation with anastomosis (30 of 89, 34%) p = 0.0213. Of the 36 instances with unhealed fistula, 13 (36%) could be ascribed to inadvertent bowel lesions at the reconstructive operation. In addition, univariate analysis revealed that patients with previous multiple laparotomies or with multiple operations for enterocutaneous fistula healed less likely and had higher mortality. A low serum albumin, high white blood cell count, high C-reactive protein concentration, high fistula output, total parenteral nutrition, and operation for recurrent fistula were associated with death together with long operation time and operative bleeding, both indicators of surgical complexity. Over time, staged surgery avoiding anastomosis increased from 27% to 57%. Mortality decreased from 12% to 6%, and healing increased from 73% to 94%. Chronic inflammation, malnutrition, and liver failure causing an impaired healing capacity are important reasons for failure. Staged operation without primary anastomosis may allow the patient to reverse this condition and improve outcome. The high surgical complexity is a negative factor that requires careful planning of the operation.

    This report was prepared to support development of the Department of Energy Environmental Management cost infrastructure -- a new capability to independently estimate and analyze costs. Currently, the cost data are reported according to a structure that blends level of effort tasks with product and process oriented tasks. Also. the budgetary inputs are developed from prior year funding authorizations and from contractor-developed parametric estimates that have been adjusted to planned funding levels or appropriations. Consequently, it is difficult for headquarters and field-level activities to use actual cost data and technical requirements to independently assess the costs generated and identify trends, potential cost savings from process improvements, and cost reduction strategies.

    From the very outset of scientific Psychology, psychologists have shown interest for drugs and their effects on behavior. This has given rise to numerous contributions, mostly in the form of Psychopharmacology publications. The aim of this study was to quantitatively evaluate these contributions and compare them with other academic disciplines related to Psychopharmacology. Using the PubMed database, we retrieved information about articles from 15 journals included in the Pharmacology and Pharmacy category of the Journal Citation Reports database for a 21-year period (1987 to 2007). There were 37540 articles which about 52% were represented by 3 journals. About 70% of psychology publications were represented by 2 of these journals. Psychology departments accounted for the 11% of the published papers, which places Psychology third behind Psychiatry and Pharmacology, which contributed to 22.69 and 13% respectively. Psychology contributed to the greatest number of studies in 3 journals, second in 3 and third in 8. This report represents the first effort to explore the contribution of academic Psychology to the multidisciplinary science of psychopharmacology. Although leaders of production of psychopharmacology research were from Psychiatry and Pharmacology, Psychology departments are an important source of studies and thus of knowledge in the field of Psychopharmacology.

    Arterial blood gas analysis is relevant in chronic obstructive pulmonary disease (COPD) management. The aim of this study was to evaluate whether the use of a blood gas analyzer in pulmonology departments improves the clinical, operational and economic outcomes when compared with clinical laboratory measurements. It is an observational prospective study. 112 patients were selected. After specimen collection, the measurement was performed both in pulmonology office as point-of-care and in laboratory. We evaluated clinical outcomes (modification of the indication of long-term oxygen therapy (LTOT) according to results, changes in blood gas analysis results, relationship of the partial pressure of oxygen (PaO2) obtained in the medical visit and velocity of change of the PaO2, influence of total haemoglobin concentration and the change in PaO2), operational outcomes (turnaround time (TAT) from specimen collection to receiving the blood gas analysis report) and economic outcomes (overall cost per process of patient care). There were discrepancies in the indication of LTOT in 13.4% of patients. All parameters showed changes. PaO2 levels showed changes in 2 ways, though they frequently increase over time. The correlation was not good in the other two clinical outcomes. The median TATs in pulmonology office were 1 min versus 79 in laboratory, with 52 min for specimen preparation and transport and 17 min for TAT intralaboratory. The overall cost for the 112 patients in pulmonology office and laboratory was 16,769.89€ and 22,260.97€ respectively. The use of a blood gas analyzer in a pulmonology office improves clinical, operational and economic outcomes when compared with clinical laboratory.

    Appendectomy is one of the most common emergency operations. Prophylaxis against infective complications involves post-operative antibiotics. There is no consensus as to the optimum antibiotic regimen. This study aimed to assess the relation between the duration of the post-operative antibiotic administration and intra-abdominal infections (IAIs). All patients who underwent appendectomy between September 1, 2009, and August 31, 2010, were identified. The appearance of the appendix at operation, post-operative antibiotics, white blood cell count, and temperature at the time of conversion of intravenous (IV) to oral antibiotics were compiled. IAIs were assessed as the final outcome. Two hundred sixty six patients underwent appendectomy-188 for simple appendicitis and 78 for complicated appendicitis. There were 18 IAIs (6.8%) overall, 10 (12.8%) after complicated appendicitis and eight (4.2%) after simple appendicitis. Prolonging antibiotics beyond the operation in the simple appendicitis group did not alter the incidence of IAI. Similarly, in the complicated appendicitis group, prolonging antibiotics beyond five days did not alter the incidence of IAI. Furthermore, in patients with complicated appendicitis, the presence of leukocytosis, fever, or both when IV antibiotics were converted to oral drugs was associated with the development of IAI (p=0.013). In simple appendicitis, post-operative antibiotics may not be beneficial at all. In complicated appendicitis, prolonging the course of antibiotics was not associated with a reduced IAI rate. However, cessation of IV antibiotics when fever or leukocytosis was present was associated with IAI development.

    With growing use of automation in civilian and military contexts that engage cooperatively with humans, the operator's level of trust in the automated system is a major factor in determining the efficacy of the human-autonomy teams. Suboptimal levels of human trust in autonomy (TiA) can be detrimental to joint team performance. This mis-calibrated trust can manifest in several ways, such as distrust and complete disuse of the autonomy or complacency, which results in an unsupervised autonomous system. This work investigates human behaviors that may reflect TiA in the context of an automated driving task, with the goal of improving team performance. Subjects performed a simulated leaderfollower driving task with an automated driving assistant. The subjects had could choose to engage an automated lane keeping and active cruise control system of varying performance levels. Analysis of the experimental data was performed to identify contextual features of the simulation environment that correlated to instances of automation engagement and disengagement. Furthermore, behaviors that potentially indicate inappropriate TiA levels were identified in the subject trials using estimates of momentary risk and agent performance, as functions of these contextual features. Inter-subject and intra-subject trends in automation usage and performance were also identified. This analysis indicated that for poorer performing automation, TiA decreases with time, while higher performing automation induces less drift toward diminishing usage, and in some cases increases in TiA. Subject use of automation was also found to be largely influenced by course features.

    2012-08-01

    A modal approach is considered for sensor placement evaluation in operational modal analysis (OMA) where modal participation at individual degree of freedom (DOF) is evaluated separately for the target modes and subsequently locations are identified using these participation profiles. Modal contribution in output energy (MCOE) is proposed as modal measure to evaluate modal participation and has been applied in this modal approach framework for sensor placement evaluation. MCOE is evaluated using observability grammian for any types of response measurement (displacement, velocity or acceleration), while a system is released from any initial condition. Further, existing modal measures e.g. modal Hankel singular value (MHSV) and system norms (H2, H∞ and Hankel) are explained in perspective of OMA. To understand the efficiency of this proposed technique, MCOE is compared in terms of modal participation with existing modal measures as well as with other techniques like effective independence (EI) and modal kinetic energy (MKE). Analytical similarity is found for participation of a mode with EI method. Further, an existing large truss bridge structure is considered for comparative study based on modal participation of individual target modes along each DOF with acceleration measurement. In this comparison, MCOE technique is found to be in very good agreement with EI method as expected, while good agreement is observed with MHSV as well as norms and reasonable agreement with MKE method. Further, the adopted modal approach uses a flexible and insightful methodology for sensor location evaluation for multiple target modes.

    The interest for robust automatic modal parameter extraction techniques has increased significantly over the last years, together with the rising demand for continuous health monitoring of critical infrastructure like bridges, buildings and wind turbine blades. In this study a novel, multi-stage clustering approach for Automated Operational Modal Analysis (AOMA) is introduced. In contrast to existing approaches, the procedure works without any user-provided thresholds, is applicable within large system order ranges, can be used with very small sensor numbers and does not place any limitations on the damping ratio or the complexity of the system under investigation. The approach works with any parametric system identification algorithm that uses the system order n as sole parameter. Here a data-driven Stochastic Subspace Identification (SSI) method is used. Measurements from a wind tunnel investigation with a composite cantilever equipped with Fiber Bragg Grating Sensors (FBGSs) and piezoelectric sensors are used to assess the performance of the algorithm with a highly damped structure and low signal to noise ratio conditions. The proposed method was able to identify all physical system modes in the investigated frequency range from over 1000 individual datasets using FBGSs under challenging signal to noise ratio conditions and under better signal conditions but from only two sensors.

    Highlights: • The assembly was used for the lithium free-surface flow experiments at 300 °C. • The integrity of steel was decreased due to carburizing from lithium. • It was proven that carbon control in lithium is important for corrosion protection. - Abstract: A lithium test assembly used for lithium-free surface flow experiments at 300 °C for 1200 h at Osaka University was analyzed metallographically to verify the design of the lithium target of the International Fusion Materials Irradiation Facility (IFMIF). Certain irregularities such as traces of high-speed lithium flow at a maximum velocity of 15 m/s were observed at the tip of the nozzle. Mottled unevenness with numerous microcracks a few microns deep was detected at the inlet of the nozzle, the velocity ratio of which was 0.1–0.4 as compared with the nozzle tip. A thin, altered layer developed on the surface of these regions because of carbide formation. It is believed that the microcracks were nucleated by thermal transients at the start or stop of operations of the lithium loop. These slight irregularities could be the result of exfoliation of the altered layer because of the high-speed lithium flow caused by the increased hardness of the altered layer as compared with that of the base metal. The metallurgical analysis proved for the first time that carbon control in lithium is also important for corrosion and erosion protection of the IFMIF components.

  17. The shape operator for differential analysis of images.

    Avants, Brian; Gee, James

    2003-07-01

    This work provides a new technique for surface oriented volumetric image analysis. The method makes no assumptions about topology, instead constructing a local neighborhood from image information, such as a segmentation or edge map, to define a surface patch. Neighborhood constructions using extrinsic and intrinsic distances are given. This representation allows one to estimate differential properties directly from the image's Gauss map. We develop a novel technique for this purpose which estimates the shape operator and yields both principal directions and curvatures. Only first derivatives need be estimated, making the method numerically stable. We show the use of these measures for multi-scale classification of image structure by the mean and Gaussian curvatures. Finally, we propose to register image volumes by surface curvature. This is particularly useful when geometry is the only variable. To illustrate this, we register binary segmented data by surface curvature, both rigidly and non-rigidly. A novel variant of Demons registration, extensible for use with differentiable similarity metrics, is also applied for deformable curvature-driven registration of medical images.

    Full Text Available Global Positioning System (GPS has made a great evolution in different aspects of modern agricultural sectors. Today, a growing number of crop producers are using GPS and other modern electronic and computer equipments to practice Site Specific Management (SSM and precision agriculture. This technology has the potential in agricultural mechanization by providing farmers with a sophisticated tool to measure yield on much smaller scales as well as precisely determination and automatic storing of variables such as field time, working area, machine travel distance and speed, fuel consumption and yield information. This study focuses on how to interpret and process raw GPS data for operational analysis of farm machinery. Exact determinations of field activities using GPS data along with accurate measurements and records of yield provide an integrated tool to calculate field efficiency and field machine index which in turn increases machine productivity and labor saving. The results can also provide graphical tools for visualizing machine operator’s performance as well as making decision on field and machine size and selection.

  19. Advanced microgrid design and analysis for forward operating bases

    Science.gov (United States)

    Reasoner, Jonathan

    This thesis takes a holistic approach in creating an improved electric power generation system for a forward operating base (FOB) in the future through the design of an isolated microgrid. After an extensive literature search, this thesis found a need for drastic improvement of the FOB power system. A thorough design process analyzed FOB demand, researched demand side management improvements, evaluated various generation sources and energy storage options, and performed a HOMERRTM discrete optimization to determine the best microgrid design. Further sensitivity analysis was performed to see how changing parameters would affect the outcome. Lastly, this research also looks at some of the challenges which are associated with incorporating a design which relies heavily on inverter-based generation sources, and gives possible solutions to help make a renewable energy powered microgrid a reality. While this thesis uses a FOB as the case study, the process and discussion can be adapted to aide in the design of an off-grid small-scale power grid which utilizes high-penetration levels of renewable energy.

    Government- and public-sponsored groups are increasingly demanding greater accountability by the Department of Energy`s weapons complex. Many of these demands have focused on the development of a positive safety climate, one that not only protects workers onsite, but also the surrounding populace and environment as well. These demands are, in part, a response to findings which demonstrate a close linkage between actual organizational safety performance and the organization`s safety climate, i.e., the collective attitudes employees hold concerning the level of safety in their organization. This paper describes the approach taken in the systematic assessment of the safety climate at EG&G Rocky Flats Plant (RFP).

    Full Text Available Background & objective: Human error is one of the main causes of accidents. Due to the unreliability of the human element and the high-risk nature of demining operations, this study aimed to assess and manage human errors likely to occur in such operations. Methods: This study was performed at a demining site in war zones located in the West of Iran. After acquiring an initial familiarity with the operations, methods, and tools of clearing minefields, job task related to clearing landmines were specified. Next, these tasks were studied using HTA and related possible errors were assessed using ATHEANA. Results: de-mining task was composed of four main operations, including primary detection, technical identification, investigation, and neutralization. There were found four main reasons for accidents occurring in such operations; walking on the mines, leaving mines with no action, error in neutralizing operation and environmental explosion. The possibility of human error in mine clearance operations was calculated as 0.010. Conclusion: The main causes of human error in de-mining operations can be attributed to various factors such as poor weather and operating conditions like outdoor work, inappropriate personal protective equipment, personality characteristics, insufficient accuracy in the work, and insufficient time available. To reduce the probability of human error in de-mining operations, the aforementioned factors should be managed properly.

    The utilization of ambulances in low- and middle-income countries is limited. The aim of this study was to ascertain frequency of ambulance use and characteristics of patients brought into emergency departments (EDs) through ambulance and non-ambulance modes of transportation. The Pakistan National Emergency Departments Surveillance (Pak-NEDS) was a pilot active surveillance conducted in seven major tertiary-care EDs in six main cities of Pakistan between November 2010 and March 2011. Univariate and multivariate logistic regression was performed to investigate the factors associated with ambulance use. Out of 274,436 patients enrolled in Pak-NEDS, the mode of arrival to the ED was documented for 94. 9% (n = 260,378) patients, of which 4.1% (n = 10,546) came to EDs via ambulances. The mean age of patients in the ambulance group was significantly higher compared to the mean age of the non-ambulance group (38 ± 18.4 years versus 32.8 ± 14.9 years, p-value ambulance group was head injury (12%) while among non-ambulance users it was fever (12%). Patients of all age groups were less likely to use an ambulance compared to those >45 years of age (p-value ambulances for those with injuries was 3.5 times higher than those with non-injury complaints (p-value ambulance were 7.2 times more likely to die in the ED than non-ambulance patients after adjustment for other variables in the model. Utilization of ambulances is very low in Pakistan. Ambulance use was found to be more among the elderly and those presenting with injuries. Patients presenting via ambulances were more likely to die in the ED.

  5. Performance and Degradation Analysis of Operating PV Systems

    Da Silva Freire, Felipe

    The environmental concerns together with the decrease in technology cost lead the solar market to growth rapidly along the last decade. The photovoltaic (PV) systems are one of the solar energy alternatives and the silicon solar cells are currently the most widespread technology. Photovoltaic (PV) modules are considered the most reliable component of a photovoltaic system. The reliability and lifetime depends on the modules energy conversion performance and degradation modes. The analysis of monitoring data give insights about the PV system performance along its service time. The comparison between this data and mathematical models configure a way to predict the futures and new PV installations performance. The goal of this study is to understand the PV systems performance and degradation along its lifetime. A mathematical model was employed to predict the power output of a real, relatively new operating PV system with respect to environmental parameters temperature, irradiance and cloud coverage. The model used is based on one diode ideality factor and takes into account the parasitic series resistance. The results have been compared with the actual PV output data collected for the year 2014 and show good correlation. As the model predicts the system power output assuming the system in new conditions, the deviation in performance of the real data in comparison to the modeling results need to be further investigated for systems in service for longer time. For this propose, the study presents a condensed review of various causes of degradation in silicon PV modules and techniques to observe and investigate these degradation mechanisms. Major effects on output performance exhibit increase in observed ideality factor n2 and recombination current J02 primarily caused by decrease in minority carrier lifetime, shunts and increase in series resistance. The study further, investigates the governing degradation modes on a ten years old PV crystalline silicon module

    Full Text Available Giving up health recommendations and care against medical advice is a setback that may happen in daily health work. In a pilot study made at the Department of Infectious Diseases in Hospital Gregorio Marañón (Madrid, Spain, during the first five months in 1998, the incidence of leaving against medical advice was 12,3 times higher than the mean in that hospital (7,03% vs 0,57%. Patients involved in this kind of event were drug abusers with acute infectious problems in a HIV primary infection or a multiple drug dependency. 42% of this patients returned to the hospital in the next 15 days. The research group thought out to study this problem under this hypothesis: Leaving against medical advice, besides having harmful consequences for the patient and the public health, produces an increase in the cost and the stay of the patient in hospital.The main objective of the research was to set up the economic the deviation in the cost/stay of a group of patients that had left against medical advice or in a regular process. It is a prospective and observational study. We studied 284 drug abusers staying in the Department of Infectious Diseases between Oct, 1st, 1999 and Sept, 30th, 2000. The research variables were: 1. Sociodemographic: Initials, , age, sex, and history number. 2. Clinical: Leaving medical diagnosis, returning medical diagnosis. 3. Administrative: Group of Related Diagnosis (GRD, admission date, leaving date, returning date and estimated cost of the episode. All episodes were grouped by kind of leaving and GRD. The cost/stay was calculated adjusted to GRD, and the deviations inside GRD were analyzed in the regular leaving group and the leaving against medical advice group.Results: Around 90% admission episodes were grouped in 6 GRD: 714 (47.92%, 541 (8.85%, 709 (8.85%, 710 (7,81%, 101 (7,29% y 715 (7,29%. The Pneumonia in HIV (GRD 714 caused the majority of the admissions. Global deviation adjusted to cost/stay was 29,44% (more expensive

    The ratio of male and female patients during the study period did not change (men 89%, women — 11 %. Single fractures that do not require surgical treatment were dominated. Operating activities during the study period of fracture increased. For 5 years, the number of complications of traumatic injuries remained the same. Conclusion. Statistical analysis of traumatic injuries of the maxillofacial region shows that the average age of the patients decreased by almost 5 years, reduced average hospital stay. Most of the patients were admitted to the profile department in the early period (up to 3 days after preparation, but 21.6% of the patients were received only with the development of complications. The article concludes that there is a need to find new methods of diagnosis, treatment and prevention of complications of traumatic injuries.

    Physical violence is defined as deliberate use of physical force likely to result in trauma, bodily injury, pain, or impairment. Present study is pioneering effort to evaluate mechanisms and sociodemographic features of physical violence targeting the elderly in Turkey and to investigate preventive measures. Database records and forensic reports were analyzed in this retrospective study of 54 elderly patients with trauma as result of physical violence who were admitted to emergency department of Şanlıurfa Training and Research Hospital between January 2012 and July 2013. Of the 54 patients evaluated, 50 (92.4%) were male. History of experiencing previous violence was described by 55.6% (n=30) of the patients. Instances of repeat violence and firearm injuries most often occurred in the home (p=0.006, p=0.007). Need for surgical treatment was also greater among cases that occurred in the home (p=0.016). Firearm injury, recurrent violence, and surgical treatment rates were higher among cases that occurred in the home. Urgent preventive measures are especially needed for the elderly who have already been victims of physical violence.

    Full Text Available Emergency medicine is an upcoming discipline that is still under development in many countries. Therefore, it is important to gain insight into the organization and patients presenting to the Emergency Department (ED. The aim of this cross-sectional study was to provide an epidemiological description of complaints and referrals of the patients visiting the ED of the Ruijin Hospital in Shanghai, China. A questionnaire was developed and completed for a convenience sample of all patients presenting to the Triage Desk of the ED. The study was performed in June 2008. A total of 2183 questionnaires were completed. The most common complaints were fever (15%, stomach/abdominal pain (15%, vertigo/dizziness (11%, and cough (10%. Following triage, patients were predominantly referred to an internist (41%, neurologist (14%, pulmonologist (11%, or general surgeon (9%. This study provides a better understanding of the reason for the ED visit and the triage system at the ED of the Ruijin Hospital. The results can be used in order to improve facilities appropriate for the specific population in the ED.

    Full Text Available Buddy programs help newcomers to smooth transition. The programs also try to increase the performance of the new personnel, give them a moral support and provide a proper atmosphere. This study aims to figure out the deficiencies of the buddy program implemented in Bingol Anti-Terror Police Department (BATPD and try to develop effective solutions for the program’s shortages. Thus, the newcomers are able to adapt to the organization in the fastest way without losing time and energy. In this study, the researcher applied observations and interviews to measure the effectiveness of the program. The participants were selected all of the newcomers who joined the organization in 2012. Data collection process took almost 12 months. According to results of the research, insufficient physical conditions of the unit, multitasking character of the personnel, and incompetent buddies are three reasons that hinder the program from being more successful. Training programs for buddies, focusing on one task at the one time, and more comfortable designed atmosphere in the organization are potential solutions for a better program.

    2015-06-01

    Full Text Available Motivation is a highly individual matter. It depends not only on the actual needs of the employee, but also on his personality, experience and scale of values. The employee work motivation directly influences the company productivity. In order to achieve the maximum level of motivation, managers need to know their needs and motivating factors of employees they supervise. Money is the key motivation factor for people, who need money to maintain their own existence. Non-financial factors of motivation also have a growing importance on the individual employee motivation. The main objective of this paper is to determinate the main intrinsic and extrinsic factors of employee motivation, and its effect on the provided service quality in the "Postal Traffic - Department in Novi Sad". The research is based on Herzberg's Two-factor theory. The results of the research showed, that majority of the factors is rated fairly high. The "Salary" is the lowest rated factor, while the factor "Colleagues" have the highest effect on employee motivation.

    2014-05-01

    Full Text Available The appropriate management of minor head injury (MHI in patients receiving oral anticoagulant (OAC is unclear. In this retrospective study, we focused on elderly patients (>65 years treated with OAC, presented to our emergency department with MHI between 2004 and 2010. Three hundred and six patients with MHI were taking OAC: we documented 7.19% hemorrhages at the first computed tomography (C; 18.19% deaths; 50.1% spontaneous reabsorptions; 22.73% deteriorations of intracranial bleeding without surgical intervention (for clinical comorbidity, and 4.55% neurosurgical interventions. We documented a second positive CT scan in 2 patients (1.51% who had no symptoms and remained asymptomatic during observation. In both cases, intracranial bleeding resolved spontaneously. The mean international normalized ratio (INR value was 2.26, higher in the group of patients with bleeding (2.74 than in the group without bleeding (2.19. We found a significant increased risk in patients with posttraumatic loss of consciousness [odds ratio (OR 28.3], diffuse headache (OR 14.79, vomiting (OR 14.2 and neurological signs (OR 5.27. We did not reach significance in patients with post-traumatic amnesia. Our data confirm the need for a CT scan of any patients on OAC with MHI. None of our patients developed any symptoms or signs during observation, and only 2 patients developed an intracranial hemorrhage in the second CT scan with a favorable evolution. Our data need to be confirmed with an observational study, but we suggest that the second CT could be reserved for patients developing symptoms and signs during observation. We also underline the role of the INR in the stratification of risk.

  5. Time-series Analysis of Heat Waves and Emergency Department Visits in Atlanta, 1993 to 2012.

    2017-05-31

    Heat waves are extreme weather events that have been associated with adverse health outcomes. However, there is limited knowledge of heat waves' impact on population morbidity, such as emergency department (ED) visits. We investigated associations between heat waves and ED visits for 17 outcomes in Atlanta over a 20-year period, 1993-2012. Associations were estimated using Poisson log-linear models controlling for continuous air temperature, dew-point temperature, day of week, holidays, and time trends. We defined heat waves as periods of consecutive days with temperatures beyond the 98th percentile of the temperature distribution over the period from 1945-2012. We considered six heat wave definitions using maximum, minimum, and average air temperatures and apparent temperatures. Associations by heat wave characteristics were examined. Among all outcome-heat wave combinations, associations were strongest between ED visits for acute renal failure and heat waves defined by maximum apparent temperature at lag 0 [relative risk (RR) = 1.15; 95% confidence interval (CI): 1.03-1.29], ED visits for ischemic stroke and heat waves defined by minimum temperature at lag 0 (RR = 1.09; 95% CI: 1.02-1.17), and ED visits for intestinal infection and heat waves defined by average temperature at lag 1 (RR = 1.10; 95% CI: 1.00-1.21). ED visits for all internal causes were associated with heat waves defined by maximum temperature at lag 1 (RR = 1.02; 95% CI: 1.00, 1.04). Heat waves can confer additional risks of ED visits beyond those of daily air temperature, even in a region with high air-conditioning prevalence. https://doi.org/10.1289/EHP44.

    Full Text Available Background: Escherichia coli (E. coli is a frequent uropathogen in urinary tract infections (UTI. Widespread resistance to sulfamethoxazole-trimethoprim (SMX-TMP and increasing resistance to fluoroquinolones amongst these isolates has been recognized. There are limited data demonstrating risk factors for resistance to both SMX-TMP and fluoroquinolones.Objectives: This study was conducted to assess for the prevalence of community resistance amongst E. coli isolates to SMX-TMP and levofloxacin in ambulatory patients discharged from the emergency department (ED.Methods: Adults presenting for evaluation and discharged from the ED with a diagnosis of an E. coli UTI were retrospectively reviewed. Utilizing demographic and clinical data the prevalence of E. coli resistance and risk factors associated with SMX-TMP- and fluoroquinolone-resistant infection were determined. Results: Among the 222 patients, the mean rates of E. coli susceptibility to levofloxacin and SMX-TMP were 82.4% and 72.5%, respectively. Significant risk factors for resistance to SMX-TMP included prior antibiotic use (p=0.04 and prior diagnosis of UTI (p= 0.01. Significant risk factors for resistance to levofloxacin included: male gender, age, presence of hypertension, diabetes, chronic respiratory disease, nursing home resident, previous antibiotic use, previous diagnosis of UTI, existence of renal or genitourinary abnormalities, and prior surgical procedures (p <0.05 for all comparisons. The number of hospital days prior to initial ED evaluation (p<0.001 was determined to be a predictive factor in hospital and ED readmission. Conclusions: These results suggest that conventional approaches to monitoring for patterns of susceptibility may be inadequate. It is imperative that practitioners develop novel approaches to identifying patients with risk factors for resistance. Identification of risk factors from this evaluation should prompt providers to scrutinize the use of these agents in

    This paper is concerned with describing the spectrum of the difference operator K:l{sub α}{sup p}(Z,X)→l{sub α}{sup p}(Z......athscrKx)(n)=Bx(n−1),  n∈Z,  x∈l{sub α}{sup p}(Z,X), with a constant operator coefficient B, which is a bounded linear operator in a Banach space X. It is assumed that K acts in the weighted space l{sub α}{sup p}(Z,X), 1≤p≤∞, of two-sided sequences of vectors from X. The main results are obtained in terms of the spectrum σ(B) of the operator coefficient B and properties of the weight function. Applications to the study of the spectrum of a differential operator with an unbounded operator coefficient (the generator of a strongly continuous semigroup of operators) in weighted function spaces are given.

    We consider classes of integral operators on the spaces of square-integrable functions on the sphere and of locally integrable functions on Lobachevsky space. The kernels of these operators depend only on the distance between points in the spherical and hyperbolic geometry, respectively. These operators are intertwining for the quasi-regular representation of the corresponding Lie group, and this enables us to evaluate their spectra and diagonalize the operators themselves. As applications, we take the Minkowski problem and the Funk-Hecke theorem for Euclidean space R{sup n}. A generalization is obtained of the Funk-Hecke theorem in the case of hyperbolic space R{sup n-1,1} with indefinite inner product.

    Wolfe, R. R.

    1975-01-01

    Subjects related to future STS operations concepts were investigated. The majority of effort was directed at assessing the benefits of automated space servicing concepts as related to improvements in payload procurement and shuttle utilization. Another subject was directed at understanding shuttle upper stage software development and recurring costs relative to total program projections. Space serving of automated payloads is addressed by examining the broad spectrum of payload applications with the belief that shared logistic operations will be a major contributor to reduction of future program costs. However, there are certain requirements for support of payload operations, such as availability of the payload, that may place demands upon the shuttle fleet. Because future projections of the NASA Mission Model are only representative of the payload traffic, it is important to recognize that it is the general character of operations that is significant rather than service to any single payload program.

    The aim of this study is to analyze and visualize the distribution of patients visiting the periodontology department at a dental college hospital, using a geographic information system (GIS) to utilize these data in patient care and treatment planning, which may help to assess the risk and prevent periodontal diseases. Basic patient information data were obtained from Dankook University Dental Hospital, including the unit number, gender, date of birth, and address, down to the dong (neighborhood) administrative district unit, of 306,656 patients who visited the hospital between 2007 and 2014. The data of only 26,457 patients who visited the periodontology department were included in this analysis. The patient distribution was visualized using GIS. Statistical analyses including multiple regression, logistic regression, and geographically weighted regression were performed using SAS 9.3 and ArcGIS 10.1. Five factors, namely proximity, accessibility, age, gender, and socioeconomic status, were investigated as the explanatory variables of the patient distribution. The visualized patient data showed a nationwide scale of the patient distribution. The mean distance from each patient's regional center to the hospital was 30.94±29.62 km and was inversely proportional to the number of patients from the respective regions. The distance from a regional center to the adjacent toll gate had various effects depending on the local distance from the hospital. The average age of the patients was 52.41±12.97 years. Further, a majority of regions showed a male dominance. Personal income had inconsistent results between analyses. The distribution of patients is significantly affected by the proximity, accessibility, age, gender and socioeconomic status of patients, and the patients visiting the periodontology department travelled farther distances than those visiting the other departments. The underlying reason for this needs to be analyzed further.

    Background: Heatwaves are one of the most deadly weather-related events in the United States and account for more deaths annually than hurricanes, tornadoes, floods, and earthquakes combined. However, there are few statistically rigorous studies of the effect of heatwaves on emergency department (ED) arrivals. A better understanding of this relationship can help hospitals plan better and provide better care for patients during these types of events. Methods: A retrospective review of all ED patient arrivals that occurred from April 15 through August 15 for the years 2008 through 2013 was performed. Daily patient arrival data were combined with weather data (temperature and humidity) to examine the potential relationships between the heat index and ED arrivals as well as the length of time patients spend in the ED using generalized additive models. In particular the effect the 2012 heat wave that swept across the United States, and which was hypothesized to increase arrivals was examined. Results: While there was no relationship found between the heat index and arrivals on a single day, a non-linear relationship was found between the mean three-day heat index and the number of daily arrivals. As the mean three-day heat index initially increased, the number of arrivals significantly declined. However, as the heat index continued to increase, the number of arrivals increased. It was estimated that there was approximately a 2% increase in arrivals when the mean heat index for three days approached 100°F. This relationship was strongest for adults aged 18-64, as well as for patients arriving with lower acuity. Additionally, a positive relationship was noted between the mean three-day heat index and the length of stay (LOS) for patients in the ED, but no relationship was found for the time from which a patient was first seen to when a disposition decision was made. No significant relationship was found for the effect of the 2012 heat wave on ED arrivals, though it

    Full Text Available This study aimed to determine the methods to prove the validity of logical arguments used by the college students, from the department of mathematics education, and to reveal students’ reasons for selection of the method they used. Among the qualitative research designs, case study was the methodology of the current study. The participants of the study consisted of 76 students who were in their third year in college and who were registered for Introduction to Algebra course. One result of the study was that all three solution methods (classical mathematical operations, truth table, rules of inference were utilized by the students while the rules of inferences were the most preferred solution method among all. Moreover, the fact that students who applied the rules of inferences were more successful in reaching the correct solution than the rest also confirmed the efficacy of the method of rules of inferences. Another result of the study was that students’ reasons for selecting the method of rules of inferences mainly included that it requires less steps and that it is more applicable. Moreover, students utilizing the rules of inferences also stated that the rules of inferences helped them to reveal the concepts behind the logical arguments beside the fact that this method was more efficient in acquiring the solution. On the other hand, students using the truth table or classical mathematical operations techniques highlighted that their preferences were mainly due to their confidence in using these techniques since they were instructed on these techniques in their past courses.

    We analyzed the US incidence of emergency department (ED) visits and hospitalizations for falls from skiing, snowboarding, skateboarding, roller-skating, and nonmotorized scooters in 2011. The outcome was hospital admission from the ED. The primary analysis compared pediatric patients aged 1 to 17 years to adults aged 18 to 44 years. The analysis used ICD-9 E-codes E885.0 to E885.4 using discharge data from the Nationwide Emergency Department Sample, Healthcare Cost and Utilization Project, Agency for Healthcare Research and Quality. Approximately 214 000 ED visits met study criteria. Skiing injuries had the highest percentage of hospitalizations (3.30% in pediatric patients and 6.65% in adults 18-44 years old). Skateboard and snowboard injuries were more likely to require hospitalization than roller skating injuries in pediatric patients (odds ratio = 2.42; 95% CI = 2.14-2.75 and odds ratio = 1.83; 95% CI =1.55-2.15, respectively). In contrast, skateboard and snowboard injuries were less severe than roller-skating injuries in adults.

    Bacterial infections are an important issue in current clinical medicine. The severity of infectious diseases has increased dramatically in recent years, which is also due to increasing numbers of resistant bacteria, including strains producing broad-spectrum beta-lactamases. The study aimed at determining the prevalence of ESBL- and AmpC-positive Enterobacteriaceae at the Department of Neonatology, University Hospital Olomouc. Enterobacteriaceae were isolated from clinical samples from infants hospitalized at the Department of Neonatology, University Hospital Olomouc over a period of 2 years. ESBL- and AmpC-positive isolates were subjected to basic genetic analysis. In the study period, a total of 1,526 isolates of the Enterobacteriaceae family were identified, including 55 (3.6%) cases of the ESBL phenotype and 17 (1.1%) AmpC-positive isolates. Genetic analysis of ESBL-positive isolates revealed a majority of CTX-M enzymes. Among AmpC beta-lactamases, the EBC, CIT, DHA, and MOX types were detected. An Escherichia coli strain was isolated with mutations in the promoter region of the ampC chromosomal gene that are associated with overproduction of the relevant enzyme.

    Full Text Available With the increasing number of old people in all western countries and increasing life expectancy at birth, many seniors spend the last period of their life with various afflictions that may lead to cardiac arrest. Bystander cardiopulmonary resuscitation (CPR increases survival rates. Octogenarians are the fastest growing segment of the population and despite empirical evidence that CPR is of questionable effectiveness in seniors with comorbidities, it is still the only treatment among life-sustaining ones. Cardiopulmonary resuscitation is frequently unsuccessful, but if survival is achieved, a fairly good quality of life can be expected. Various papers analyzed the effect of CPR in hospitalized patients or in cardiac arrest occurring at home or in public places, while less is known about events occurring in the emergency room (ER. We performed a retrospective analysis of cardiac arrest events occurred in ER within 54 months: we analyzed 415,001 records of ER visits (from 01/01/1999 to 30/06/2003 in San Giovanni Addolorata Hospital. Data were analyzed in terms of age and outcome. We identified 475 records with the outcome of death in ER or death on arrival. Out of them, we selected 290 medical records which had sufficient data to be analyzed. Of the 290 patients evaluated, 225 died in ER, 18 were deemed to die on arrival, and 47 survived the cardiac arrest and were admitted to intensive care unit (ICU. The overall mortality was 0.11%, while the incidence of the selected events was 0.072%. The mean age of the analyzed population was 71.3 years. The only possible diagnosis was often cardiac arrest, though most of the times we could specify and group the diagnosis even better. The analysis of the procedures showed that cardiac arrest treated by direct current (DC shock was similarly distributed in different age groups, and no difference was detectable between the two groups. The mean age of the patients who underwent tracheal intubation (TI was

    Pharmacoeconomics is young rapidly developing science that uses economic, clinical and epidemiologic methods. It studies adequate use of therapeutics giving guidelines towards rational utilization of the resources in health care. Pharmacoeconomics indentifies estimates and compares costs and clinical outcomes of different strategies giving the best solution: optimal cost/benefit ratio. These studies can be used to estimate existing programs and plan the new ones. The aim of this paper was to carry out pharmacoeconomic study on the non-steroid anti-inflamatory drugs (NSAID) use in canton Tuzla, to compare costs of medication with highly selective cyclooxygenase 2 (COX-2) inhibitors and nonselective NSAIDs and to calculate medication costs of the bleeding from upper parts of gastrointestinal tract. Study covers period from January to April 2004. Meta-analysis of selected clinical studies on safe and efficiency of NSAIDs was simultaneously conducted. Our results show that hospital treatment costs of the high-risk patients group significantly exceeds their potential medication costs with highly selective COX-2 inhibitors. Simultaneous use of non-selective NSAIDs with antacids has justification only in the low-risk group with mild gastrointestinal disturbances.

    2004-03-01

    The work reported in this document involves a development effort to provide combat commanders and systems engineers with a capability to explore and optimize system concepts that include operational concepts as part of the design effort. An infrastructure and analytic framework has been designed and partially developed that meets a gap in systems engineering design for combat related complex systems. The system consists of three major components: The first component consists of a design environment that permits the combat commander to perform 'what-if' types of analyses in which parts of a course of action (COA) can be automated by generic system constructs. The second component consists of suites of optimization tools designed to integrate into the analytical architecture to explore the massive design space of an integrated design and operational space. These optimization tools have been selected for their utility in requirements development and operational concept development. The third component involves the design of a modeling paradigm for the complex system that takes advantage of functional definitions and the coupled state space representations, generic measures of effectiveness and performance, and a number of modeling constructs to maximize the efficiency of computer simulations. The system architecture has been developed to allow for a future extension in which the operational concept development aspects can be performed in a co-evolutionary process to ensure the most robust designs may be gleaned from the design space(s).

    Full Text Available The main goal of the study is to define dialogue dimensions in order to describe the interaction within peer dyads and potentially connect them with formal operations development in the less competent participants. Its significance is related to rare investigations of this subject in the context of formal operations development and to practical implications regarding peer involvement in education process. The sample included 316 students aged 12 and 14. The research had an experimental design: pre-test, intervention and post-test. In the pre-test and the post-test phases students solved the formal operations test BLOT. According to the pre-test results, 47 dyads were formed where less and more competent students jointly solved tasks from BLOT. Their dialogues were coded by 14 dimensions operationalized for this purpose. Correlations between the dialogue dimensions indicate clearly distinguished positive and negative interaction patterns. There are no connections between dialogue dimensions and progress of less competent adolescents on BLOT in the entire sample, but several are found in the subsamples. Arguments exchange seems to be the most encouraging dialogue feature regarding formal operations development, particularly in older students. This confirms relevant research data and the expectations about peers’ constructive role in fostering cognitive development.

    Preventing airborne infections during a surgery has been always an important issue to deliver effective and high quality medical care to the patient. One of the important sources of infection is particles that are distributed through airborne routes. Factors influencing infection rates caused by airborne particles, among others, are efficient ventilation and the arrangement of surgical facilities inside the operating room. The paper studies the ventilation airflow pattern in an operating room in a hospital located in Tehran, Iran, and seeks to find the efficient configurations with respect to the ventilation system and layout of facilities. This study uses computational fluid dynamics (CFD) and investigates the effects of different inflow velocities for inlets, two pressurization scenarios (equal and excess pressure) and two arrangements of surgical facilities in room while the door is completely open. The results show that system does not perform adequately when the door is open in the operating room under the current conditions, and excess pressure adjustments should be employed to achieve efficient results. The findings of this research can be discussed in the context of design and controlling of the ventilation facilities of operating rooms.

    Fichet, Sylvain; Tonero, Alberto; Teles, Patricia Rebello

    2017-08-01

    When the Standard Model is interpreted as the renormalizable sector of a low-energy effective theory, the effects of new physics are encoded into a set of higher-dimensional operators. These operators potentially deform the shapes of Standard Model differential distributions of final states observable at colliders. We describe a simple and systematic method to obtain optimal estimations of these deformations when using numerical tools, like Monte Carlo simulations. A crucial aspect of this method is minimization of the estimation uncertainty: We demonstrate how the operator coefficients have to be set in the simulations in order to get optimal results. The uncertainty on the interference term turns out to be the most difficult to control and grows very quickly when the interference is suppressed. We exemplify our method by computing the deformations induced by the O3 W operator in W+W- production at the LHC, and by deriving a bound on O3 W using 8 TeV CMS data.

    The mission of the United States Department of Energy (DOE) National Nuclear Security Administrations (NNSA's) Global Threat Reduction Initiative (GTRI) is to identify, secure, recover and facilitate the disposition of vulnerable nuclear and high-risk radioactive materials around the world that pose a threat to the United States and the international community. The GTRI's unique mission to reduce and protect vulnerable nuclear and radiological materials located at civilian sites worldwide directly addresses recommendations of the 9/11 Commission1, and is a vital part of the President's National Security Strategy and the Global Initiative. The GTRI Remote Monitoring System (RMS) is a standalone security system that includes radiation and tamper alarms, and CCTV; which can be transmitted securely over the Internet to multiple on-site and off-site locations. Through our experiences during installation of the system at 162 sites, plus feedback received from Alarm Response Training course participants, site input to project teams and analysis of trouble calls; indications were that current system training was lacking and inconsistent. A survey was undertaken to gather information from RMS users across the nation, to evaluate the current level of training and determine what if any improvements needed to be made. Additional questions were focused on the operation of the RMS software. The training survey was initially sent electronically to 245 users at the RMS sites and achieved a 37.6% return rate. Analysis of the resulting data revealed that 34.6% of the respondents had not received training or were unsure if they had, despite the fact that vendor engineers provide training at installation of the system. Any training received was referred to as minimal, and brief, not documented, and nothing in writing. 63.7% of respondents said they were either not at all prepared or only somewhat prepared to use the RMS software required to effectively operate the

    A matrix based on coupling of cost (always, better and control) analysis and criticality (vital, essential and desirable) analysis was employed for drug inventory containing 129 items of drug store in the Department of Community Medicine of a Medical College in Delhi. The annual drug expenditure incurred on 129 drug items for the year 2010-2011 was found to be Rs. 4,35,847.85. On always, better and control analysis, 18.6, 24.0 and 57.4% drugs were found to be always, better and control category items, respectively, amounting for 69.1, 20.8 and 10.1% of annual drug expenditure. About 13.2 (17), 38.8 (50) and 48.0% (62) items were found to be vital, essential and desirable category items, respectively, amounting for 18.7, 49.5 and 31.8% of annual drug expenditure. Based on always, better and control-vital, essential and desirable matrix analysis there were 37 (28.68%) items in category I, 53 (41.09%) items in category II and 39 (30.23%) items in category III, amounting for 73.0, 22.2 and 4.8% of annual drug expenditure, respectively. To conclude, scientific inventory management tools are needed to be applied in routine for efficient management of the pharmacy stores as it contributes to not only in improvement in patient care but also judicious use of resources as well.

    This paper presents a multifunction control strategy for the stable operation of Distributed Generation (DG) units during grid integration. The proposed control model is based on Direct Lyapunov Control (DLC) theory and provides a stable region for the appropriate operation of DG units during grid...... integration. Using DLC technique in DG technology can provide the continuous injection of maximum active power in fundamental frequency from the DG source to the grid, compensating all reactive power and harmonic current components of grid-connected loads through the integration of DG link into the grid....... Application of this concept can guarantee to reduce the stress on the grid during the energy demand peak. Simulation results are presented to demonstrate the proficiency and performance of the proposed DLC technique in DG technology....

    Full Text Available Let $L_alpha$ be the Bessel operator with matrix coefficients defined on $(0,infty$ by $$ L_alpha U(t = U''(t+ {I/4-alpha^2over t^2}U(t, $$ where $alpha$ is a fixed diagonal matrix. The aim of this study, is to determine, on the positive half axis, a singular second-order differential operator of $L_alpha+Q$ kind and its various properties from only its spectral characteristics. Here $Q$ is a matrix-valued function. Under suitable circumstances, the solution is constructed by means of the spectral function, with the help of the Gelfund-Levitan process. The hypothesis on the spectral function are inspired on the results of some direct problems. Also the resolution of Fredholm's equations and properties of Fourier-Bessel transforms are used here.

    Full Text Available The instrument landing system (ILS is the most popular landing aid in the world. It is a distance-angled support system for landing in reduced visibility, while its task is the safe conduct of the aircraft from the prescribed course landing on the approach path. The aim of this study is to analyse the correctness of the ILS in simulated conditions. The study was conducted using a CKAS MotionSim5 flight simulator in the Simulation Research Laboratory of the Institute of Combustion Engines and Transport at Poznan University of Technology. With the advancement of technical equipment, it was possible to check the operation of the system in various weather conditions. Studies have shown that the impact of fog, rain and snow on the correct operation of the system is marginal. Significant influence has been observed, however, during landing in strong winds.

    Fang, Yan-Long; Vassiliev, Dmitri

    2016-01-01

    We study the (massless) Dirac operator on a 3-sphere equipped with Riemannian metric. For the standard metric the spectrum is known. In particular, the eigenvalues closest to zero are the two double eigenvalues +3/2 and -3/2. Our aim is to analyse the behaviour of eigenvalues when the metric is perturbed in an arbitrary smooth fashion from the standard one. We derive explicit asymptotic formulae for the two eigenvalues closest to zero. Note that these eigenvalues remain double eigenvalues under perturbations of the metric: they cannot split because of a particular symmetry of the Dirac operator in dimension three (it commutes with the antilinear operator of charge conjugation). Our asymptotic formulae show that in the first approximation our two eigenvalues maintain symmetry about zero and are completely determined by the increment of Riemannian volume. Spectral asymmetry is observed only in the second approximation of the perturbation process. As an example we consider a special family of metrics, the so-cal...

    Loop heat pipes (LHPs) are heat transfer devices whose operating principle is based on the evaporation/condensation of a working fluid, and which use the capillary pumping forces to ensure the fluid circulation. Their major advantages as compared to heat pipes are an ability to operate against gravity and a greater maximum heat transport capability. In this paper, a literature review is carried out in order to investigate how various parameters affect the LHP operational characteristics. This review is based on the most recent published experimental and theoretical studies. After a reminder of the LHP operating principle and thermodynamic cycle, their operating limits are described. The LHP thermal resistance and maximum heat transfer capability are affected by the choice of the working fluid, the fill charge ratio, the porous wick geometry and thermal properties, the sink and ambient temperature levels, the design of the evaporator and compensation chamber, the elevation and tilt, the presence of non-condensable gases, the pressure drops of the fluid along the loop. The overall objective for this paper is to point the state-of-the-art for the related technology for future design and applications, where the constraints related to the LHPs are detailed and discussed.

    Full Text Available Introduction: The balance between revenue and cost of an organization/system is essential to maintain its survival and quality of services. Emergency departments (ED are one of the most important parts of health care delivery system. Financial discipline of EDs, by increasing the efficiency and profitability, can directly affect the quality of care and subsequently patient satisfaction. Accordingly, the present study attempts to investigate failure mode and effects analysis (FMEA method in identifying the problems leading to the loss of ED revenue and offer solutions to help fix these problems. Methods: This prospective cohort study investigated the financial records of ED patients and evaluated the effective errors in reducing the revenue in ED of Imam Hossein hospital, Tehran, Iran, from October 2007 to November 2009. The whole department was divided based on FMEA into one main system and six subsystems. The study was divided in two phases. In the first phase, the problems leading to the loss in the revenue in each subsystem were identified and weighted to four groups using risk priority number (RPN, and the solutions for fixing them were planned. Then, at the second phase discovered defects in the first phase were fixed according to their priority. Finally, the impact of each solution was compared before and after interventions using the repeated measure ANOVA test. Results: At last, 100 financial records of ED patients were evaluated during the first phase of the study. The average of ED revenue in the six months of the first phase was 73.1±3.65 thousands US dollar/month. 12 types of errors were detected in the predefined subsystems.

    The military is undergoing a significant transformation as it modernizes for the information age and adapts to address an emerging asymmetric threat beyond traditional cold war era adversaries. Techniques such as traditional large-scale, joint services war gaming analysis are no longer adequate to support program evaluation activities and mission planning analysis at the enterprise level because the operating environment is evolving too quickly. New analytical capabilities are necessary to address modernization of the Department of Defense (DoD) enterprise. This presents significant opportunity to Sandia in supporting the nation at this transformational enterprise scale. Although Sandia has significant experience with engineering system of systems (SoS) and Complex Adaptive System of Systems (CASoS), significant fundamental research is required to develop modeling, simulation and analysis capabilities at the enterprise scale. This report documents an enterprise modeling framework which will enable senior level decision makers to better understand their enterprise and required future investments.

  15. Transcutaneous versus blood carbon dioxide monitoring during acute noninvasive ventilation in the emergency department - a retrospective analysis.

    Horvath, Christian Michael; Brutsche, Martin Hugo; Baty, Florent; Rüdiger, Jochen Julius

    2016-01-01

    Transcutaneous measurement of carbon dioxide (PtCO2) has been suggested as an alternative to invasively obtained PaCO2 for the monitoring of patients with hypercapnic respiratory failure during noninvasive ventilation (NIV). Current data on monitoring in hypoxaemic respiratory failure are scarce and show conflicting results in hypercapnic patients in the emergency department. We performed a retrospective comparison of real-time PtCO2 (SenTec Digital Monitor) and arterial/venous carbon dioxide tension (PaCO2/PvCO2) measurements in patients with severe hypoxaemic and/or hypercapnic respiratory failure during NIV. Agreement between PtCO2 and PaCO2/PvCO2 was the primary endpoint. Bland-Altman analysis and linear regression were used. 102 patients had at least one matched measurement of PtCO2 and PaCO2/PvCO2. For patients with arterial blood gas analysis, the mean difference was 0.46 kPa at baseline (95% confidence interval [CI] 0.23 to 0.60, limits of agreement 95% CI -0.54 to 1.45) and 0.12 kPa after NIV (95% CI -0.04 to 0.29, limits of agreement 95% CI: -0.61 to 0.86). The linear regression analysis found a correlation R2 of 0.88 (p 8 kPa was associated with a lesser degree of agreement between the levels of PtCO2 and PaCO2/PvCO2 (p Transcutaneous PCO2 monitoring shows a good concordance with PaCO2 and is a reliable, feasible, patient-friendly and safe alternative to repeated blood gas analysis for patients with severe hypoxaemic and/or hypercapnic respiratory failure receiving emergency NIV in the emergency department. An initial blood gas analysis to evaluate the respiratory and metabolic state and to rule out a significant discrepancy compared with the transcutaneous measurement is recommended.

    This paper contains new data on the chemical composition of the essential oil of Lippia alba (Mill.) N. E. Brown, as well as an overview of the available literature. Although the composition of the essential oil of this species is well-documented, discrepancies between the reported results suggest that many chemotypes and morphotypes exist. The analysis of essential oils obtained from the leaves of samples from three different locations in the French Overseas Departments (French Guiana, Martinique, and two different places in Guadeloupe) have shown that the composition of each one is quite different. This new data, along with a review and discussion of published studies, enabled us to establish seven distinct chemotypes. Possible connections between these chemotypes and morphotypes already described were also investigated.

    Background Health services across the world increasingly face pressures on the use of expensive hospital services. Better organisation and delivery of primary care has the potential to manage demand and reduce costs for hospital services, but routine primary care services are not open during evenings and weekends. Extended access (evening and weekend opening) is hypothesized to reduce pressure on hospital services from emergency department visits. However, the existing evidence-base is weak, largely focused on emergency out-of-hours services, and analysed using a before-and after-methodology without effective comparators. Methods and Findings Throughout 2014, 56 primary care practices (346,024 patients) in Greater Manchester, England, offered 7-day extended access, compared with 469 primary care practices (2,596,330 patients) providing routine access. Extended access included evening and weekend opening and served both urgent and routine appointments. To assess the effects of extended primary care access on hospital services, we apply a difference-in-differences analysis using hospital administrative data from 2011 to 2014. Propensity score matching techniques were used to match practices without extended access to practices with extended access. Differences in the change in “minor” patient-initiated emergency department visits per 1,000 population were compared between practices with and without extended access. Populations registered to primary care practices with extended access demonstrated a 26.4% relative reduction (compared to practices without extended access) in patient-initiated emergency department visits for “minor” problems (95% CI -38.6% to -14.2%, absolute difference: -10,933 per year, 95% CI -15,995 to -5,866), and a 26.6% (95% CI -39.2% to -14.1%) relative reduction in costs of patient-initiated visits to emergency departments for minor problems (absolute difference: -£767,976, -£1,130,767 to -£405,184). There was an insignificant
