Sample records for accommodating practical constraints

  1. Accommodation of practical constraints by a linear programming jet select. [for Space Shuttle

    Bergmann, E.; Weiler, P.

    1983-01-01

    An experimental spacecraft control system will be incorporated into the Space Shuttle flight software and exercised during a forthcoming mission to evaluate its performance and handling qualities. The control system incorporates a 'phase space' control law to generate rate change requests and a linear programming jet select to compute jet firings. Posed as a linear programming problem, jet selection must represent the rate change request as a linear combination of jet acceleration vectors where the coefficients are the jet firing times, while minimizing the fuel expended in satisfying that request. This problem is solved in real time using a revised Simplex algorithm. In order to implement the jet selection algorithm in the Shuttle flight control computer, it was modified to accommodate certain practical features of the Shuttle such as limited computer throughput, lengthy firing times, and a large number of control jets. To the authors' knowledge, this is the first such application of linear programming. It was made possible by careful consideration of the jet selection problem in terms of the properties of linear programming and the Simplex algorithm. These modifications to the jet select algorithm may by useful for the design of reaction controlled spacecraft.

  3. GPS constraints on shear accommodation in the northern Walker Lane, western Nevada, USA

    Bormann, J. M.; Hammond, W. C.; Kreemer, C. W.; Blewitt, G.; Wesnousky, S. G.

    2009-12-01

    The Walker Lane is a zone of active intracontinental transtension that accommodates approximately 10 mm/yr of right-lateral deformation, up to 20-25% of Pacific-North America relative plate motion. Between Walker Lake and Lake Tahoe, the Walker Lane lacks optimally oriented strike-slip faults to accommodate northwest-directed dextral shear. In this region Quaternary deformation appears to be concentrated in a northwest-trending series of north-striking, normal fault-bounded basins. To address the question of how shear is transferred through this portion of the Walker Lane, we combine GPS data from the University of Nevada, Reno’s semi-continuous MAGNET GPS network with observations from EarthScope’s Plate Boundary Observatory to present a new velocity field for the Walker Lane with an average station spacing of 20 km. Measurements in MAGNET (http://geodesy.unr.edu/networks) began in January 2004 and now provide time series of up to 6 years for the longest running sites and >3 years for all sites. Together with recent improvements in GPS data processing models using the GIPSY-OASIS II software, this allows us to estimate rates with uncertainty well below 1 mm/yr. These recent improvements include the use of reprocessed GPS orbits from the IGS Analysis Center at JPL. Our GPS processing now includes satellite and station antenna calibrations, random-walk tropospheric zenith delay and gradients using the GMF mapping function, second-order ionospheric corrections, global-scale ambiguity resolution using our custom Ambizap software, and our custom Great Basin spatially-filtered reference frame. The velocity solution shows a smooth and continuous increase in shear across the Walker Lane in addition to NW-SE directed extension. We use a block model driven by GPS velocities to estimate the role that vertical axis rotation of fault-bounded blocks and slip on basin-bounding faults play in shear accommodation. The block model also allows us to incorporate published

  4. Vergence and accommodation to multiple-image-plane stereoscopic displays: ``real world'' responses with practical image-plane separations?

    MacKenzie, Kevin J.; Dickson, Ruth A.; Watt, Simon J.

    2012-01-01

    Conventional stereoscopic displays present images on a single focal plane. The resulting mismatch between the stimuli to the eyes' focusing response (accommodation) and to convergence causes fatigue and poor stereo performance. One solution is to distribute image intensity across a number of widely spaced image planes--a technique referred to as depth filtering. Previously, we found this elicits accurate, continuous monocular accommodation responses with image-plane separations as large as 1.1 Diopters (D, the reciprocal of distance in meters), suggesting that a small number of image planes could eliminate vergence-accommodation conflicts over a large range of simulated distances. Evidence exists, however, of systematic differences between accommodation responses to binocular and monocular stimuli when the stimulus to accommodation is degraded, or at an incorrect distance. We examined the minimum image-plane spacing required for accurate accommodation to binocular depth-filtered images. We compared accommodation and vergence responses to changes in depth specified by depth filtering, using image-plane separations of 0.6 to 1.2 D, and equivalent real stimuli. Accommodation responses to real and depth-filtered stimuli were equivalent for image-plane separations of ~0.6 to 0.9 D, but differed thereafter. We conclude that depth filtering can be used to precisely match accommodation and vergence demand in a practical stereoscopic display.

    2011-03-01

    Conventional stereoscopic displays present images on a single focal plane. The resulting mismatch between the stimuli to the eyes' focusing response (accommodation) and to convergence causes fatigue and poor stereo performance. One promising solution is to distribute image intensity across a number of relatively widely spaced image planes - a technique referred to as depth filtering. Previously, we found this elicits accurate, continuous monocular accommodation responses with image-plane separations as large as 1.1 Diopters, suggesting that a relatively small (i.e. practical) number of image planes is sufficient to eliminate vergence-accommodation conflicts over a large range of simulated distances. However, accommodation responses have been found to overshoot systematically when the same stimuli are viewed binocularly. Here, we examined the minimum image-plane spacing required for accurate accommodation to binocular depth-filtered images. We compared accommodation and vergence responses to step changes in depth for depth-filtered stimuli, using image-plane separations of 0.6-1.2 D, and equivalent real stimuli. Accommodation responses to real and depth-filtered stimuli were equivalent for image-plane separations of ~0.6-0.9 D, but inaccurate thereafter. We conclude that depth filtering can be used to precisely match accommodation and vergence demand in a practical stereoscopic display, using a relatively small number of image planes.

  6. Accommodation of China’s Industrial Heritage in Urban Conservation Practices (Ⅱ)

    Peter G. Rowe; Har Ye Kan

    2012-01-01

    In recent years, the conservation of industrial heritage in China has gained increasing attention within the broader context of urban conservation practices. For both policy-makers and scholars, accommodating this industrial heritage will emerge as a pertinent issue for consideration as a growing number of industrial architectural legacies dating from the Republican and Maoist eras come under (re)development pressures. This paper thus traces the development of industrial heritage conservation practices in China and discusses several dilemmas intrinsic to this type of conservation, including issues of authenticity, representativeness, and distinction. Based on comparative case studies from China and other international precedents, this paper also seeks to illustrate the different approaches that could be pursued while still attaining a balance between competing interests and claims.

    Full Text Available This experiment is designed to study the characteristics of village chicken husbandry practice, marketing and constraints in eastern Ethiopia. The study was conducted from July in four selected districts in the highlands of eastern Ethiopia (Haramaya, Kersa, Jarso and Meta. A total of 80 chicken owner households were randomly selected and interviewed using a structured questionnaire. Data on characteristics of village chicken production, feeds and feeding practices, housing, management of chicken and eggs, Marketing, diseases and constraints of village chicken production system were collected. Scavenging chicken production system is observed in all households of the districts. Average flock size of chickens in the study area was 9.4 birds and varied between 4 and 17 birds. In the present study, 82% of the households provide overnight housing within the family house for their chicken. Scavenging is the only feeding system encountered in all study districts with little grain supplementation. Most of the chicken are owned and managed by women (36.75%. Selling of unprocessed eggs and live chickens is mainly practiced. External parasites (mites, Coccidiosis and Newcastle disease were the most important and prevailing diseases in the study area with 39%, 38% and 34% incidence rates, respectively. The magnitude of occurrence of the parasites and diseases were higher in the wet season. Poor genetic quality, lack of extension service, inadequate veterinary service and poor management were the main constraints of village poultry production in the study area.

  10. Accommodating practical constraints for intensity-modulated radiation therapy by means of compensators

    Meyer, J

    2001-01-01

    intensity distribution, inverse modelling of the radiation attenuation within the compensator is required. Two novel and independent approaches, based on deconvolution and system identification, respectively, are proposed to accomplish this. To compare the approach with the 'rival' state of the art beam modulation technique, theoretical and experimental examination of the modulated fields generated by manufactured compensators and multileaf collimators is presented. This comparison focused on the achievable resolution of the intensity modulated beams in lateral and longitudinal directions. To take into account the characteristics of a clinical environment, a comprehensive study has been carried out to investigate the suitability of the most common commercially available treatment couch systems for their suitability for IMRT treatments. In this context, an original rule based advisory system has been developed to alert the operator of any potential collision of the beam with the moveable supporting structures ...

  14. Public governance-constraints and challenges for social work practice

    Jorunn Theresia Jessen

    2015-12-01

    Full Text Available In the wake of public sector reforms, the work environment of professionals is changing; there is more description of results and outputs and tighter requirements of front-line work. The changes taking place address a shift towards managerial forms of control and organizational regulations in a range of Western countries. However, the new managerial regimes have different consequences for professionals as objects and subjects of governance. This paper investigates the extent of managerial and administrative regulations in the Norwegian social services, questioning the asserted negative impacts on professional autonomy in social work practice. The empirical data derive from a survey conducted among practitioners and managers in 125 local agencies, and compared to bureaucratic rules and agency procedures that set constraints, the new management model allows both autonomy and flexibility in choosing means and measures in various fields. Most of all, collegial support plays a significant role in providing professional standards for decision-making. The increase of management techniques and standard procedures in public administration concurrently challenges social work values, translating the social services into a field of more regulatory practices.

  18. Neuroscience and the law: philosophical differences and practical constraints.

    Martell, Daniel A

    2009-01-01

    Controversies surrounding the value of neuroscience as forensic evidence are explored from the perspective of the philosophy of mind, as well as from a practical analysis of the state of the scientific research literature. At a fundamental philosophical level there are profound differences in how law and neuroscience view the issue of criminal responsibility along the continuum from free will to determinism. At a more practical level, significant limitations in the current state of neuroimaging research constrain its ability to inform legal decision-making. Scientifically supported and unsupported forensic applications for brain imaging are discussed, and recommendations for forensic report writing are offered. PMID:19267425

  1. The practical considerations of dose constraints in diagnostic medical departments using ionizing radiation

    The term 'dose constraint' has been used in radiological protection since 1990. Its practical application has varied from country to country to the present day. The authors of this paper believe that it is an underestimated tool for the purpose of radiological protection. This study aims to estimate local dose constraints for workers in conventional nuclear medicine and radiology departments, on the basis of doses received in the last 3 to 4 years by different groups of workers. The levels of exposure to employees of the nuclear medicine department correspond well to levels in other countries, but for employees belonging to the radiology department, the levels are significantly lower. Unification of the practical application of dose constraints and legislation concerning their specific values would increase the relevance and effectiveness of these operational units. This is a playing field for radiation safety officers for the determination and widespread publication of local dose constraints in their particular medical departments. (authors)

  4. Beyond the Practical Dilemmas and Conceptual Reductions: the Emergence of an ‘Accommodative Consciousness’ in the Alternative Globalization Movement

    Seyed Abdolhamed Hosseini

    2006-02-01

    Full Text Available This paper attempts to show the emergence of a new ideological trend within the global field of resistance against the corporate-led globalization. This ideological trend, coined here the alter-globalization trend, is ideal-typically constructed in terms of its associated mode of social thought. The newly developed perspectives and cognitive transformations inside the global field of resistance convey a new mode of in-praxis thought, named here accommodative cognition. This heralds the formation of alternative principles for creating emancipatory knowledges and flexible solidarities. The paper draws on certain discursive evidence from the alter-globalization trend to show that the complexity of globalizing society and contemporary collective action is realized through the open spaces of dialogue and dispute introduced by the movement. This has resulted in the emergence of intellectual demands for transcending contradictions that are rooted in the post-1970s disputes between modernist and post-modernist, and materialist and post-materialist thoughts. Two other features of this new mode of cognition are: (1 a growing inclination to cut across incompatible conceptions of social polarities (i.e. around issues like class, gender, race, cultural identity, ethnicity, nationality and sexual orientation in establishing a flexible solidarity based on accommodating the Other’s interest and identity into the process of affirming the Self; and (2 understanding the complexities of globalization in terms of its structural unevenness, contradictions and multidimensionality.

    2012-04-01

    Full Text Available Abstract Background The practice of exclusive breastfeeding is still low despite the associated benefits. Improving the uptake and appropriating the benefits will require an understanding of breastfeeding as an embodied experience within a social context. This study investigates breastfeeding practices and experiences of nursing mothers and the roles of grandmothers, as well as the work-related constraints affecting nurses in providing quality support for breastfeeding mothers in Southwest Nigeria. Methods Using a concurrent mixed method approach, a structured questionnaire was administered to 200 breastfeeding mothers. In-depth interviews were also held with breastfeeding mothers (11, nurses (10 and a focus group discussion session with grandmothers. Results Breastfeeding was perceived as essential to baby's health. It strengthens the physical and spiritual bond between mothers and their children. Exclusive breastfeeding was considered essential but demanding. Only a small proportion (19% of the nursing mothers practiced exclusive breastfeeding. The survey showed the major constraints to exclusive breastfeeding to be: the perception that babies continued to be hungry after breastfeeding (29%; maternal health problems (26%; fear of babies becoming addicted to breast milk (26%; pressure from mother-in-law (25%; pains in the breast (25%; and the need to return to work (24%. In addition, the qualitative findings showed that significant others played dual roles with consequences on breastfeeding practices. The desire to practice exclusive breastfeeding was often compromised shortly after child delivery. Poor feeding, inadequate support from husband and conflicting positions from the significant others were dominant constraints. The nurses decried the effects of their workload on providing quality supports for nursing mothers. Conclusion Breastfeeding mothers are faced with multiple challenges as they strive to practice exclusive breastfeeding. Thus

  7. Evaluation of pig production practices, constraints and opportunities for improvement in smallholder production systems in Kenya.

    Mbuthia, Jackson Mwenda; Rewe, Thomas Odiwuor; Kahi, Alexander Kigunzu

    2015-02-01

    This study evaluated pig production practices by smallholder farmers in two distinct production systems geared towards addressing their constraints and prospects for improvement. The production systems evaluated were semi-intensive and extensive and differed in remoteness, market access, resource availability and pig production intensity. Data were collected using structured questionnaires where a total of 102 pig farmers were interviewed. Qualitative and quantitative research methods were employed to define the socioeconomic characteristics of the production systems, understanding the different roles that pigs play, marketing systems and constraints to production. In both systems, regular cash income and insurance against emergencies were ranked as the main reasons for rearing pigs. Marketing of pigs was mainly driven by the type of production operation. Finances, feeds and housing were identified as the major constraints to production. The study provides important parameters and identifies constraints important for consideration in design of sustainable production improvement strategies. Feeding challenges can be improved through understanding the composition and proper utilization of local feed resources. Provision of adequate housing would improve the stocking rates and control mating. PMID:25448534

  8. Energy Market Transparency: Analyzing the Impacts of Constraint Relaxation and Out-of-Market Correction Practices in Electric Energy Markets

    Al-Abdullah, Yousef Mohammad

    This work presents research on practices in the day-ahead electric energy market, including replication practices and reliability coordinators used by some market operators to demonstrate the impact these practices have on market outcomes. The practice of constraint relaxations similar to those an Independent System Operator (ISO) might perform in day-ahead market models is implemented. The benefits of these practices are well understood by the industry; however, the implications these practices have on market outcomes and system security have not been thoroughly investigated. By solving a day-ahead market model with and without select constraint relaxations and comparing the resulting market outcomes and possible effects on system security, the effect of these constraint relaxation practices is demonstrated. Proposed market solutions are often infeasible because constraint relaxation practices and approximations that are incorporated into market models. Therefore, the dispatch solution must be corrected to ensure its feasibility. The practice of correcting the proposed dispatch solution after the market is solved is known as out-of-market corrections (OMCs), defined as any action an operator takes that modifies a proposed day-ahead dispatch solution to ensure operating and reliability requirements. The way in which OMCs affect market outcomes is illustrated through the use of different corrective procedures. The objective of the work presented is to demonstrate the implications of these industry practices and assess the impact these practices have on market outcomes.

  12. Contextual Shaping of Student Design Practices: The Role of Constraint in First-Year Engineering Design

    Goncher, Andrea M.

    thResearch on engineering design is a core area of concern within engineering education, and a fundamental understanding of how engineering students approach and undertake design is necessary in order to develop effective design models and pedagogies. This dissertation contributes to scholarship on engineering design by addressing a critical, but as yet underexplored, problem: how does the context in which students design shape their design practices? Using a qualitative study comprising of video data of design sessions, focus group interviews with students, and archives of their design work, this research explored how design decisions and actions are shaped by context, specifically the context of higher education. To develop a theoretical explanation for observed behavior, this study used the nested structuration. framework proposed by Perlow, Gittell, & Katz (2004). This framework explicated how teamwork is shaped by mutually reinforcing relationships at the individual, organizational, and institutional levels. I appropriated this framework to look specifically at how engineering students working on a course-related design project identify constraints that guide their design and how these constraints emerge as students interact while working on the project. I first identified and characterized the parameters associated with the design project from the student perspective and then, through multi-case studies of four design teams, I looked at the role these parameters play in student design practices. This qualitative investigation of first-year engineering student design teams revealed mutual and interconnected relationships between students and the organizations and institutions that they are a part of. In addition to contributing to research on engineering design, this work provides guidelines and practices to help design educators develop more effective design projects by incorporating constraints that enable effective design and learning. Moreover, I found

  13. A novel string structure for economic dispatch problems with practical constraints

    The novel string structure for solving the economic dispatch problems through genetic algorithm (GA) is presented. The proposed string scheme can effectively prevent getting infeasible solution when evolutionary computation methods are preceded. Therefore, it can increase the searching efficiency and also solution quality dramatically. Many nonlinear characteristics of the power generators and practical constraints, such as generation limitation, ramp rate limits, prohibited operating zone, transmission loss and nonlinear cost functions are all considered for realistic operation. The effectiveness and feasibility of the proposed method are demonstrated by three real systems, and compared with the literatures method in terms of the solution quality and computation efficiency. The experimental shows encouraging results that the proposed approach was indeed capable of obtaining higher quality and efficiency solutions in economic dispatch problems

    P. T. Gangasagare

    Full Text Available The study was conducted to review the situation of dairying in Marathwada with the objectives to identify major constraints of the dairy farmers in adapting the recommended animal husbandry practices. The survey work was carried out for the milk pocket areas in eight districts of the Marathwada region. Out of 144 dairy farmers, 109 farmers cared crossbred animals; 65 out of 85 dairy farmers adapted cooling arrangement to cross-bred cows during summer; 35 of 45 adapted washing their animals during summer; 98 of 230 dairy farmers followed vaccination to their animals; 45 of 230 dairy farmers followed de-worming their animals; 37 of 230 adapted to control the ecto-parasite; 65 of 230 reacted for removal old debris; 105 of 230 dairy farmers adapted A.I. policy and only 88 of 230 dairy farmers were positive for the animals insurance. Higher proportion of the farmers has accepted the importance of crossbred cows. Higher numbers of farmers have positive response to cool their animals. Significantly more numbers of farmers did not care to vaccinate and accept other health measures for their animals. Non-significant differences between dairy farmers adapting and non-adapting A.I. practices were recorded while significant (P>0.01 difference was observed between the farmers adapting and not adapting the insurance policy.

  16. Practical Constraint K-Segment Principal Curve Algorithms for Generating Railway GPS Digital Map

    Dewang Chen

    2013-01-01

    Full Text Available In order to obtain a decent trade-off between the low-cost, low-accuracy Global Positioning System (GPS receivers and the requirements of high-precision digital maps for modern railways, using the concept of constraint K-segment principal curves (CKPCS and the expert knowledge on railways, we propose three practical CKPCS generation algorithms with reduced computational complexity, and thereafter more suitable for engineering applications. The three algorithms are named ALLopt, MPMopt, and DCopt, in which ALLopt exploits global optimization and MPMopt and DCopt apply local optimization with different initial solutions. We compare the three practical algorithms according to their performance on average projection error, stability, and the fitness for simple and complex simulated trajectories with noise data. It is found that ALLopt only works well for simple curves and small data sets. The other two algorithms can work better for complex curves and large data sets. Moreover, MPMopt runs faster than DCopt, but DCopt can work better for some curves with cross points. The three algorithms are also applied in generating GPS digital maps for two railway GPS data sets measured in Qinghai-Tibet Railway (QTR. Similar results like the ones in synthetic data are obtained. Because the trajectory of a railway is relatively simple and straight, we conclude that MPMopt works best according to the comprehensive considerations on the speed of computation and the quality of generated CKPCS. MPMopt can be used to obtain some key points to represent a large amount of GPS data. Hence, it can greatly reduce the data storage requirements and increase the positioning speed for real-time digital map applications.

    2015-01-01

    A novel optimization algorithm is proposed to solve single and multi-objective optimization problems with generation fuel cost, emission, and total power losses as objectives. The proposed method is a hybridization of the conventional cuckoo search algorithm and arithmetic crossover operations. Thus, the non-linear, non-convex objective function can be solved under practical constraints. The effectiveness of the proposed algorithm is analyzed for various cases to illustrate the effect of prac...

    Objective: Impaired gastric accommodation is one of the main symptoms in patients with functional dyspepsia. The aim of the present study was to assess gastric accommodation in patients with functional dyspepsia using single photon emission computed tomography (SPECT) imaging. Methods: Twenty-four patients with functional dyspepsia and 50 healthy volunteers as control group were enrolled in this study. All participants were given 5 mCi 99mTc-pertechtenate intravenously, served with a low fat meal, and underwent SPECT scanning 20 minutes after the meal. Results: Based on the scintigraphic data, gastric volumes were found to be significantly increased after food ingestion in both patient and control groups. We also found that while there was no significant difference between patient and control groups in terms of fasting gastric volumes, postprandial gastric volume was significantly lower in patients as compared to healthy individuals (p<0.05). Conclusion: Measuring gastric volume by using SPECT can be a valuable method in the detection of functional dyspepsia and in differentiation of this entity from other organic disorders.

  2. An improved chaotic hybrid differential evolution for the short-term hydrothermal scheduling problem considering practical constraints

    Tahir Nadeem MALIK; Salman ZAFAR; Saaqib HAROON

    2015-01-01

    Short-term hydrothermal scheduling (STHTS) is a non-linear and complex optimization problem with a set of oper-ational hydraulic and thermal constraints. Earlier, this problem has been addressed by several classical techniques;however, due to limitations such as non-linearity and non-convexity in cost curves, artificial intelligence tools based techniques are being used to solve the STHTS problem. In this paper an improved chaotic hybrid differential evolution (ICHDE) algorithm is proposed to find an optimal solution to this problem taking into account practical constraints. A self-adjusted parameter setting is obtained in differential evolution (DE) with the application of chaos theory, and a chaotic hybridized local search mechanism is embedded in DE to effectively prevent it from premature convergence. Furthermore, heuristic constraint handling techniques without any penalty factor setting are adopted to handle the complex hydraulic and thermal constraints. The superiority and effectiveness of the developed methodology are evaluated by its application in two illustrated hydrothermal test systems taken from the literature. The transmission line losses, prohibited discharge zones of hydel plants, and ramp rate limits of thermal plants are also taken into account. The simulation results reveal that the proposed technique is competent to produce an encouraging solution as com-pared with other recently established evolutionary approaches.

  5. Fixation by active accommodation

    Pahlavan, Kourosh; Uhlin, Tomas; Eklundh, Jan-Olof

    1992-11-01

    The field of computer vision has long been interested in disparity as the cue for the correspondence between stereo images. The other cue to correspondence, blur, and the fact that vergence is a combination of the two processes, accommodative vergence and disparity vergence, have not been equally appreciated. Following the methodology of active vision that allows the observer to control all his visual parameters, it is quite natural to take advantage of the powerful combination of these two processes. In this article, we try to elucidate such an integration and briefly analyze the cooperation and competition between accommodative vergence and disparity vergence on one hand and disparity and blur stimuli on the other hand. The human fixation mechanism is used as a guide-line and some virtues of this mechanism are used to implement a model for vergence in isolation. Finally, some experimental results are reported.

    In this paper we discuss the notion of "bridging" in Discourse Representation Theory as a tool to account for discourse referents that have only been established implicitly, through the lexical semantics of other referents. In doing so, we use ideas from Generative Lexicon theory, to introduce antecedents for anaphoric expressions that cannot be "linked" to a proper antecedent, but that do not need to be "accommodated" because they have some connection to the network of discourse referents that is already established.

    Full Text Available A novel optimization algorithm is proposed to solve single and multi-objective optimization problems with generation fuel cost, emission, and total power losses as objectives. The proposed method is a hybridization of the conventional cuckoo search algorithm and arithmetic crossover operations. Thus, the non-linear, non-convex objective function can be solved under practical constraints. The effectiveness of the proposed algorithm is analyzed for various cases to illustrate the effect of practical constraints on the objectives' optimization. Two and three objective multi-objective optimization problems are formulated and solved using the proposed non-dominated sorting-based hybrid cuckoo search algorithm. The effectiveness of the proposed method in confining the Pareto front solutions in the solution region is analyzed. The results for single and multi-objective optimization problems are physically interpreted on standard test functions as well as the IEEE-30 bus test system with supporting numerical and graphical results and also validated against existing methods.

  18. Organs at risk in the brain and their dose-constraints in adults and in children: A radiation oncologist’s guide for delineation in everyday practice

    Purpose: Accurate organs at risk definition is essential for radiation treatment of brain tumors. The aim of this study is to provide a stepwise and simplified contouring guide to delineate the OARs in the brain as it would be done in the everyday practice of planning radiotherapy for brain cancer treatment. Methods: Anatomical descriptions and neuroimaging atlases of the brain were studied. The dosimetric constraints used in literature were reviewed. Results: A Computed Tomography and Magnetic Resonance Imaging based detailed atlas was developed jointly by radiation oncologists, a neuroradiologist and a neurosurgeon. For each organ brief anatomical notion, main radiological reference points and useful considerations are provided. Recommended dose-constraints both for adult and pediatric patients were also provided. Conclusions: This report provides guidelines for OARs delineation and their dose-constraints for the treatment planning of patients with brain tumors

  19. Accommodation of couch constraints for coplanar intensity modulated radiation therapy

    Purpose: Three treatment couches, henceforth referred to as the standard, the variable standard and the C-arm couch, each based on a different supporting frame system, were investigated for their suitability for the delivery of a high number of coplanar beams (≥5) as may be required for intensity-modulated radiation therapy treatments. Materials and methods: A number of equispaced beam arrangements (five to nine) were examined in combination with two circular target sizes (diameter 6 and 10 cm) at different locations within an elliptical body on the investigated couches, resulting in 70 different plans per couch. A rule based advisory system determined possible intersections of the beam paths with the supporting frames of the respective treatment couch and suggested a suitable constellation for the supporting frames. In cases of intersection, a beam-couch collision was eliminated by minimal rotation of the beams from the initial equispaced beam arrangement. To investigate the effect of a rotation of the posterior-oblique beams for five, seven and nine initially equispaced beams by an angle of 10 deg., a prostate plan was generated and compared with equispaced beam arrangement. Results: Initial beam paths intersected with the standard couch in 63% of the plans, necessitating a rotation of one or two beams. It was necessary to modify the beam angles in 34% of the cases on the variable standard couch to avoid an intersection of the beams with the couch. All the plans would have been delivered satisfactorily on the C-arm couch without a rotation of beams. Simulation studies showed that the dose distribution for a prostate treatment could be affected significantly, but not detrimentally, by the rotation of the two posterior-oblique beam orientations by an angle of 10 deg

    The NASA Ames Research Center Biological Research Project (BRP) is responsible for identifying and accommodating high priority life science activities, utilizing nonhuman specimens, on the Space Station and is charged to bridge the gap between the science community and the Space Station Program. This paper discusses the approaches taken by the BRP in accomodating these research objectives to constraints imposed by the Space Station System, while maintaining a user-friendly environment. Consideration is given to the particular research disciplines which are given priority, the science objectives in each of these disciplines, the functions and activities required by these objectives, the research equipment, and the equipment suits. Life sciences programs planned by the Space Station participating partners (USA, Europe, Japan, and Canada) are compared.

  1. Developments in Accommodating Intraocular Lenses

    Zeki Tunç

    2012-07-01

    Full Text Available Technical progress in cataract surgery has decreased the incidence of severe complications in this type of surgery. The introduction of micro incision cataract surgery (MICS (sub- 2.0 mm incision allow the surgeon to achieve better postoperative control of astigmatism and higherorder aberration (HOAs with minimum induction of both. It is believed that multifocal lenses provide very successful results, however, there are limitations to these. Implantation of accommodating intraocular lenses (IOLs is an option to treat presbyopia. The IOLs work by using the continued functionality of the ciliary muscle after cataract removal. Accommodating IOLs were designed to avoid the optical side effects of multifocal IOLs. Two main design concepts exist. First, axial shift concepts rely on anterior axial movement of one or two optics creating accommodative ability. Second, curvature change designs are designed to provide significant amplitudes of accommodation with little physical displacement. Accommodative IOLs to correct astigmatism and HOAs in the future are needed. (Turk J Ophthalmol 2012; 42: 288-93

  3. Mark My Words! Linguistic Style Accommodation in Social Media

    Danescu-Niculescu-Mizil, Cristian; Dumais, Susan; 10.1145/1963405.1963509

    2011-01-01

    The psycholinguistic theory of communication accommodation accounts for the general observation that participants in conversations tend to converge to one another's communicative behavior: they coordinate in a variety of dimensions including choice of words, syntax, utterance length, pitch and gestures. In its almost forty years of existence, this theory has been empirically supported exclusively through small-scale or controlled laboratory studies. Here we address this phenomenon in the context of Twitter conversations. Undoubtedly, this setting is unlike any other in which accommodation was observed and, thus, challenging to the theory. Its novelty comes not only from its size, but also from the non real-time nature of conversations, from the 140 character length restriction, from the wide variety of social relation types, and from a design that was initially not geared towards conversation at all. Given such constraints, it is not clear a priori whether accommodation is robust enough to occur given the con...

  4. Can Partial Structures Accommodate Inconsistent Science?

    Peter Vickers

    2009-08-01

    Full Text Available The semantic approach to scientific representation is now long established as a favourite amongst philosophers of science. One of the foremost strains of this approach—the model-theoretic approach (MTA—is to represent scientific theories as families of models, all of which satisfy or ‘make true’ a given set of constraints. However some authors (Brown 2002, Frisch 2005 have criticised the approach on the grounds that certain scientific theories are logically inconsistent, and there can be no models of an inconsistent set of constraints. Thus it would seem that the MTA fails to represent inconsistent scientific theories at all, and this raises concerns about the way it represents in general. In a series of papers (1990, 1993, 1995 and a recent book (2003 da Costa and French have developed a variant of the MTA approach which they call ‘partial structures’, and which they claim can accommodate inconsistent theories. I assess this claim, looking to two theories which have been called ‘inconsistent’: Bohr’s theory of the atom and classical electrodynamics.

  5. Visual accommodation trainer-tester

    Randle, Robert J. (Inventor)

    1988-01-01

    An apparatus for training the human visual accommodation system is described. Specifically, the apparatus is useful for training personnel to volitionally control focus to the far point (normally infinity) from a position of myopia due to functional causes. The functional causes could be due, for example, to a behavioral accommodative spasm or the effects of an empty field. The device may also be used to measure accommodation, the accommodation resting position and the near and far points of vision. The device comprises a number of optical elements arranged on a single optical axis. Several of the elements are arranged in order on a movable stage in fixed relationship to each other: a light source, a lens, a target, an aperture and/or a second lens. On a base and in fixed relationship to each other are eyepiece and third lens. A stage generates an image of the target and the stage is movable with respect to the base by means of a knob. The device is utilized for the various training and test functions by following a series of procedural steps, and interchanging the apertures as necessary for the selected procedure.

  6. Theorizing accommodation in supportive home care for older people.

    Ceci, Christine; Purkis, Mary Ellen; Björnsdóttir, Kristin

    2013-01-01

    This paper examines the issue of what thinking is necessary in order to advance a notion of accommodation in the organization and provision of supportive home care for older people. Accommodation in this context is understood as responsiveness to the singularity of older adults, and we consider how this idea might be used to support opportunities for (independent) living for elders as they age and become frailer. To elaborate the question we draw on examples from our empirical work - ethnographic studies of home care practice undertaken in Canada and Iceland - and consider these examples in light of critical philosophical and social theory, particularly Agamben's (1993) work, The Coming Community. This is a relevant frame through which to consider the potential for the accommodation of the unique needs of older adults in home care because it helps us to problematize the systems through which care is accomplished and the current, dominant terms of relations between individuals and collectives. We argue that giving substance to a notion of accommodation contributes an important dimension to aligned ideas, such as patient-centeredness in care, by working to shift the intentionality of these practices. That is, accommodation, as an orientation to care practices, contests the organizational impulse to carry on in the usual way. PMID:23273554

  7. On adaptive frequency hopping to combat coexistence interference between bluetooth and IEEE 802.11b with practical resource constraints

    In contrast to traditional frequency hopping techniques, Adaptive Frequency Hopping (AFH) is a low cost and low power solution to avoid interference dynamically. While each AFH algorithm proposed previously is shown to be efficient, a detailed performance analysis of various AFH mechanisms under realistic resource constraints is yet to be done. In particular, based on our performance study on Bluetooth systems presented in this paper, we have found that the AFH mechanism adopted by IEEE 802.1...

    In Denmark, the practice of occupational medicine tends to be carried out by specialists in occupational medicine and less so by family physicians. The provision of health service to workers is therefore limited. This constraint may also apply in other developed countries and even more in countries...... with few occupational health resources.

  11. Spherical aberration, accommodation and myopia

    Tarrant, Janice

    2010-01-01

    Myopia is a condition in which the eye grows too long to match its optical focal length and represents a failure in both structure and function. Because of the potential risks of vision loss associated with high myopia, and also with corrective treatments such as refractive surgery and occasionally also with contact lenses, myopia should not be considered a benign condition. The hypothesis that hyperopic defocus from under-accommodation during near work is the driving stimulus in the progress...

  19. Soyuz/ACRV accommodation study

    Cruz, Jonathan; Gould, Marston J.; Dahlstrom, Eric

    1993-11-01

    Included is a set of viewgraphs that present the results of a study conducted at the LaRC Space Station Freedom Office at the request of the Space Station Freedom Level 1 Program Office and the JSC ACRV Project Office to determine the implications of accommodating two Soyuz TM spacecraft as Assured Crew Return Vehicles (ACRV) on the Space Station Freedom (SSF) at the Permanently Crewed Capability (PCC) stage. The study examined operational as well as system issues associated with the accommodation of the Soyuz for several potential configuration options. Operational issues considered include physical hardware clearances, worst case Soyuz departure paths, and impacts to baseline operations such as Pressurized Logistics Module (PLM) exchange, Space Station Remote Manipulator System (SSRMS) attachment, Extravehicular Activity (EVA), and automatic rendezvous and docking (AR&D). Systems impact analysis included determining differences between Soyuz interface requirements and SSF capabilities for the Electrical Power System (EPS), Thermal Control System (TCS), Communications and Tracking (C&T), Audio-Video Subsystem (A/V), Data Management System (DMS), and Environmental Control and Life Support System (ECLSS). Significant findings of this study have indicated that the current AV capability of the Soyuz will need to be increased to provide adequate departure clearances for a worst case escape from an uncontrolled SSF and that an interface element will be required to mate the Soyuz vehicles to station, provide for AR&D structural loads, and to house Soyuz-to-SSF system interfaces.

I compared Korean Child Behavior Checklist (K-CBCL which consists of internalizing factors (social withdrawal, somatic complaints, anxiety, and depression and externalizing factors (social problems, thought problems, attention problems, delinquent behavior, and aggressive behavior between RAE group and control group. Results. Two out of three internalizing indexes were significantly different between groups (somatic complaints: RAE children 50.1±4.6 and controls 46.6±5.8, P=0.026; depression/anxiety: RAE children 48.8±7.9 and controls 43.9±6.8, P=0.024. Although there was no significant difference, RAE children scored slightly higher on the externalizing behavior index. In the RAE group, the far angle of esodeviation showed a moderate correlation with withdrawn behaviors. Conclusion. Hypermetropic children with high scores on the somatic complaint and depression/anxiety subscales of the CBCL could be at high risk for developing RAE. Psychosocial problems might be related to the pathogenesis of refractive accommodative esotropia.

  1. Extra Time as an Accommodation

    Ruth Colker

    2008-04-01

    Full Text Available Although the provision of extra time has become the standard method of accommodating students with various disabilities when they take the Law School Admissions Test (LSAT or in-class timed exams, this Article suggests that we consider other means of attaining fairness on exams. Through a survey of the psychometric literature, as well as a modest empirical study, this Article argues that the rank order of students is likely to be significantly affected by the type of examination instrument used. This Article places the psychometric literature on examination results in the context of testing of prelaw students as well as law students and suggests that we place less emphasis on timed instruments in ranking students.

    Jens Anker-Hansen

    2016-01-01

    This thesis takes a departure from a view of scientific literacy as situated in participation in civic practices. From such a view, it becomes problematic to assess scientific literacy through decontextualised test items only dealing with single aspects of participation in contexts concerned with science. Due to the complexity of transferring knowledge, it is problematic to assume that people who can explain scientific theories will automatically apply those theories in life or that knowledge...

  5. Accommodation in mild traumatic brain injury

    Wesley Green, MS

    2010-05-01

    Full Text Available Accommodative dysfunction in individuals with mild traumatic brain injury (mTBI can have a negative impact on quality of life, functional abilities, and rehabilitative progress. In this study, we used a range of dynamic and static objective laboratory and clinical measurements of accommodation to assess 12 adult patients (ages 18-40 years with mTBI. The results were compared with either 10 control subjects with no visual impairment or normative literature values where available. Regarding the dynamic parameters, responses in those with mTBI were slowed and exhibited fatigue effects. With respect to static parameters, reduced accommodative amplitude and abnormal accommodative interactions were found in those with mTBI. These results provide further evidence for the substantial impact of mTBI on accommodative function. These findings suggest that a range of accommodative tests should be included in the comprehensive vision examination of individuals with mTBI.

  8. ENCOURAGING ENVIRONMENTAL MANAGEMENT AMONG SMALL AND MEDIUM ACCOMMODATIONS (SMAs THROUGH E-LEARNING INITIATIVE

    Azilah KASIM

    2009-04-01

    Full Text Available This paper is a continuance of an empirical work on hotels in a developing country and its acceptance on environmental impact. The study measured the responsiveness of small and medium accommodations (SMAs in Kuala Lumpur, Malaysia towards environmental management, by means of their awareness, attitudes and opinion on the meaning, marketability and practicality of environmental management in an accommodation property. A combination of quantitative and qualitative approach was used for the study. The study found those respondents’ perceptions on the meaning, marketability and practicality of environmental management that SMAs are generally positive about the relevance of environmental issues in their operations and their role in it. However, the SMAs do not go beyond the basic common sense of cutting their water and energy costs. The chief reason for the lack of motivation to do more is lack of awareness on how to adopt environmental management in their operations. The study also found path towards a wider adoption of environmental management among SMAs is still rough because there is very little pressure from the authorities and relevant stakeholders for them to change. Without external drivers, it is difficult to expect SMAs to go beyond their normal business activity as internal constraints and lack of guidance on how to play a more significant role in sustainable development are hampering such move. To overcome the lack of drivers, this paper is proposing e-learning as a way to promote wider understanding and acceptance on environmental management for SMAs. Thus, the paper discusses the situation by addressing key issues such as students, teachers and organizational issues, information technology delivery design and top level support, outcome assessment, flexibility as well as supplement versus substitute issues.

  11. BRANDING ORIENTATION IN THE ACCOMMODATION INDUSTRY

    Melissa Li Sa Liow

    2015-04-01

    Full Text Available This paper starts by clarifying the role of branding orientation (BO among academic studies. It shortly introduces the development of the BO concepts. The empirical part consists of a search for and analysing of academic articles using a meta-analysis that consider BO in the accommodation industry. According to the results, significant appraisal of the branding building activities among higher star rating and luxury accommodation businesses are taking place due to the increasingly demanding guests. Thus, there is an upward pressure on small and medium accommodation businesses to survive or perform well. This paper recommends that scholars study the owners-managers, employees, and customer perspectives altogether, to better comprehend how large accommodation businesses displaying BO can generate superior performance. For the small and medium accommodation businesses, the emphasis is the owners-managers perceptions since they are the main decision-makers, and due to infancy of the small and medium enterprise (SME branding application.

  12. Analyzing the Effect of Multi-fuel and Practical Constraints on Realistic Economic Load Dispatch using Novel Two-stage PSO

    Chintalapudi, V. S.; Sirigiri, Sivanagaraju

    2016-07-01

    In power system restructuring, pricing the electrical power plays a vital role in cost allocation between suppliers and consumers. In optimal power dispatch problem, not only the cost of active power generation but also the costs of reactive power generated by the generators should be considered to increase the effectiveness of the problem. As the characteristics of reactive power cost curve are similar to that of active power cost curve, a nonconvex reactive power cost function is formulated. In this paper, a more realistic multi-fuel total cost objective is formulated by considering active and reactive power costs of generators. The formulated cost function is optimized by satisfying equality, in-equality and practical constraints using the proposed uniform distributed two-stage particle swarm optimization. The proposed algorithm is a combination of uniform distribution of control variables (to start the iterative process with good initial value) and two-stage initialization processes (to obtain best final value in less number of iterations) can enhance the effectiveness of convergence characteristics. Obtained results for the considered standard test functions and electrical systems indicate the effectiveness of the proposed algorithm and can obtain efficient solution when compared to existing methods. Hence, the proposed method is a promising method and can be easily applied to optimize the power system objectives.

  16. Misconceptions and constraints

    In theory, the sterile insect technique (SIT) is applicable to a wide variety of invertebrate pests. However, in practice, the approach has been successfully applied to only a few major pests. Chapters in this volume address possible reasons for this discrepancy, e.g. Klassen, Lance and McInnis, and Robinson and Hendrichs. The shortfall between theory and practice is partly due to the persistence of some common misconceptions, but it is mainly due to one constraint, or a combination of constraints, that are biological, financial, social or political in nature. This chapter's goal is to dispel some major misconceptions, and view the constraints as challenges to overcome, seeing them as opportunities to exploit. Some of the common misconceptions include: (1) released insects retain residual radiation, (2) females must be monogamous, (3) released males must be fully sterile, (4) eradication is the only goal, (5) the SIT is too sophisticated for developing countries, and (6) the SIT is not a component of an area-wide integrated pest management (AW-IPM) strategy. The more obvious constraints are the perceived high costs of the SIT, and the low competitiveness of released sterile males. The perceived high up-front costs of the SIT, their visibility, and the lack of private investment (compared with alternative suppression measures) emerge as serious constraints. Failure to appreciate the true nature of genetic approaches, such as the SIT, may pose a significant constraint to the wider adoption of the SIT and other genetically-based tactics, e.g. transgenic genetically modified organisms (GMOs). Lack of support for the necessary underpinning strategic research also appears to be an important constraint. Hence the case for extensive strategic research in ecology, population dynamics, genetics, and insect behaviour and nutrition is a compelling one. Raising the competitiveness of released sterile males remains the major research objective of the SIT. (author)

  1. Practical Implementations of Advanced Process Control for Linear Systems

    Knudsen, Jørgen K . H.; Huusom, Jakob Kjøbsted; Jørgensen, John Bagterp

    2013-01-01

    Most advanced process control systems are based on Model Predictive Control (MPC). In this paper we discuss three critical issues for the practical implementation of linear MPC for process control applications. The rst issue is related to oset free control and disturbance models; the second issue......-regulator structure. It enables oset free control; it can be computed eciently on-line using several optimization algorithms; and accommodates soft constraint for the outputs and for shaping the set-point tracking penalty function. We report selected observations using this implementation and discuss their practical...... models and integration of the innovation errors. If the disturbances increases, oset-free control cannot be achieved without violation of process constraints. A target calculation function is used to calculate the optimal achievable target for the process. The use of soft constraints for process output...

  2. COMPARISON OF VISUAL ACUITY IN REDUCED LUMINATION AND FACILITY OF OCULAR ACCOMMODATION IN TABLE TENNIS CHAMPIONS AND NON- PLAYERS

    Ebrahim Jafarzadehpur

    2004-03-01

    Full Text Available A table tennis player should fixate at different distances; track the objects with different speed, and in different visual environment. Their visual skills must be well developed for these capabilities. Therefore, visual acuity in reduced lumination and facility of ocular accommodation those are two criteria for visual skills have been compared in table tennis players and normal non-players. Twenty-nine young table tennis champions and 29 normal matched non-players (did not take part in any racket sports game were evaluated. Basic visual and eye examinations were done for both of them. Normal results in basic examination were fundamental requirement for all the subjects. +/-2.00 sphere lenses for accommodation facility are used. An electrical current regulator changed the output light intensity of a conventional chart projector (Topcon. Light intensity decreased to 10 cd·m-2 and visual acuity tested. In comparison of visual acuity in reduced lumination and facility of ocular accommodation in table tennis champions and non-players there are significant differences (p < 0.001. In the preliminary visual tests there was not any significant different in the two groups but the results in the top level table tennis player was very uniform and in every test and the standard deviation was lesser in tennis player group than non-players. These results show that motor and sensorial functions of expert players are well developed. That is consistent with other researchers. This result was interpreted as reflecting a better perceptual system of experts to the constraints encountered during table tennis and its use in practical settings for evaluating athletes or detecting sport talents. However some visual and perceptual training that usually used in orthoptics can be used for novice table tennis player to improve their abilities

  3. Foundations of support constraint machines.

    Gnecco, Giorgio; Gori, Marco; Melacci, Stefano; Sanguineti, Marcello

    2015-02-01

    The mathematical foundations of a new theory for the design of intelligent agents are presented. The proposed learning paradigm is centered around the concept of constraint, representing the interactions with the environment, and the parsimony principle. The classical regularization framework of kernel machines is naturally extended to the case in which the agents interact with a richer environment, where abstract granules of knowledge, compactly described by different linguistic formalisms, can be translated into the unified notion of constraint for defining the hypothesis set. Constrained variational calculus is exploited to derive general representation theorems that provide a description of the optimal body of the agent (i.e., the functional structure of the optimal solution to the learning problem), which is the basis for devising new learning algorithms. We show that regardless of the kind of constraints, the optimal body of the agent is a support constraint machine (SCM) based on representer theorems that extend classical results for kernel machines and provide new representations. In a sense, the expressiveness of constraints yields a semantic-based regularization theory, which strongly restricts the hypothesis set of classical regularization. Some guidelines to unify continuous and discrete computational mechanisms are given so as to accommodate in the same framework various kinds of stimuli, for example, supervised examples and logic predicates. The proposed view of learning from constraints incorporates classical learning from examples and extends naturally to the case in which the examples are subsets of the input space, which is related to learning propositional logic clauses.

  6. Automation for Accommodating Fuel-Efficient Descents in Constrained Airspace

    Coopenbarger, Richard A.

    2010-01-01

    Continuous descents at low engine power are desired to reduce fuel consumption, emissions and noise during arrival operations. The challenge is to allow airplanes to fly these types of efficient descents without interruption during busy traffic conditions. During busy conditions today, airplanes are commonly forced to fly inefficient, step-down descents as airtraffic controllers work to ensure separation and maximize throughput. NASA in collaboration with government and industry partners is developing new automation to help controllers accommodate continuous descents in the presence of complex traffic and airspace constraints. This automation relies on accurate trajectory predictions to compute strategic maneuver advisories. The talk will describe the concept behind this new automation and provide an overview of the simulations and flight testing used to develop and refine its underlying technology.

  7. Recovery of Accommodative Capabilities of Ocular Pseudophakia

    Ivonin K.S.

    2012-12-01

    Full Text Available There are considered three modern prospective ways to solve the problem of pseudophakic presbyopia: development of induced anisometropia (monovision, and implantation of accommodative and pseudo-accommodative intraocular lens (IOL. According to the findings of numerous studies, pseudophakic monovision enables to achieve good results of close-up and distant acuity of vision without correction. However, monovision use involves such limitations as individual intolerance to anisometropia, and the lack of stereoscopic vision. Despite accommodative IOL have more potential, accommodative effect after the implantation of this type of lens is not always guaranteed. There can be several reasons for that, including inconsistency between IOL diameter and capsular sac diameter, incorrect capsulorrhexis diameter, increased or reduced ciliary muscle contraction, capsular sac fibrosis, synchysis corporis vitrei, posterior vitreous detachment, the change of lens ligament elasticity. Currently, the use of pseudo-accommodative IOL is the most effective way of pseudophakic presbyopia correction, and among them the most effective ones are bifocal refractive and diffractive IOL. But along with the recognized advantages of the lens, they have a number of disadvantages, e.g. low intermediate vision.

    Nur Mukminatien

    2012-07-01

    Full Text Available This article aims to discuss issues of World Englishes (WEs and the implications in ELT. It explores the extent to which WEs are taken into account as emerging English varieties different from inner circle varieties, how WEs should be accomodated by English teachers, and which standard to adopt to accommodate learner’s linguistic needs for international communication. It would help ELT practitioners adjust their current practices through the inclusion of varieties of WEs in developing learners’ oral communication. This offers relevant pedagogical movement to argue that changes should be made about the way English is valued and taught.

  11. Autism, Accommodation and Treatment: A Rejoinder to Chong-Ming Lim's Critique.

    Jaarsma, Pier; Welin, Stellan

    2015-11-01

    We are very grateful to Chong-Ming Lim for his thoughtful reply published in this journal on one of our articles, which motivated us to think more carefully about accommodating autistic individuals and treating autism. However we believe there are some confusions in Lim's argument. Lim uses the accommodation thesis, according to which we should accommodate autistic individuals rather than treat autism, as the starting point for his reasoning. He claims that if the accommodation thesis is right, then we should not treat autistic individuals for their autism, not even low-functioning (i.e. intellectually disabled) ones, because this would be disrespectful to all autistic individuals. We should instead limit ourselves to accommodate all autistic individuals. However, the opposition between accommodation and treatment is not valid in the case of autism, because of ambiguity in the concepts of accommodation and treatment. Moreover there is confusion in Lim's reasoning caused by omitting important facts about the practice of treating autism. PMID:26307242

  14. Anthropometric Accommodation in Space Suit Design

    Rajulu, Sudhakar; Thaxton, Sherry

    2007-01-01

    Design requirements for next generation hardware are in process at NASA. Anthropometry requirements are given in terms of minimum and maximum sizes for critical dimensions that hardware must accommodate. These dimensions drive vehicle design and suit design, and implicitly have an effect on crew selection and participation. At this stage in the process, stakeholders such as cockpit and suit designers were asked to provide lists of dimensions that will be critical for their design. In addition, they were asked to provide technically feasible minimum and maximum ranges for these dimensions. Using an adjusted 1988 Anthropometric Survey of U.S. Army (ANSUR) database to represent a future astronaut population, the accommodation ranges provided by the suit critical dimensions were calculated. This project involved participation from the Anthropometry and Biomechanics facility (ABF) as well as suit designers, with suit designers providing expertise about feasible hardware dimensions and the ABF providing accommodation analysis. The initial analysis provided the suit design team with the accommodation levels associated with the critical dimensions provided early in the study. Additional outcomes will include a comparison of principal components analysis as an alternate method for anthropometric analysis.

  17. Water Accommodation on Bare and Coated Ice

    Kong, Xiangrui

    2015-04-01

    A good understanding of water accommodation on ice surfaces is essential for quantitatively predicting the evolution of clouds, and therefore influences the effectiveness of climate models. However, the accommodation coefficient is poorly constrained within the literature where reported values vary by up to three orders of magnitude. In addition, the complexity of the chemical composition of the atmosphere plays an important role in ice phase behavior and dynamics. We employ an environmental molecular beam (EMB) technique to investigate molecular water interactions with bare and impurity coated ice at temperatures from 170 K to 200 K. In this work, we summarize results of water accommodation experiments on bare ice (Kong et al., 2014) and on ice coated by methanol (Thomson et al., 2013), butanol (Thomson et al., 2013) and acetic acid (Papagiannakopoulos et al., 2014), and compare those results with analogous experiments using hexanol and nitric acid coatings. Hexanol is chosen as a complementary chain alcohol to methanol and butanol, while nitric acid is a common inorganic compound in the atmosphere. The results show a strong negative temperature dependence of water accommodation on bare ice, which can be quantitatively described by a precursor model. Acidic adlayers tend to enhance water uptake indicating that the system kinetics are thoroughly changed compared to bare ice. Adsorbed alcohols influence the temperature dependence of the accommodation coefficient and water molecules generally spend less time on the surfaces before desorbing, although the measured accommodation coefficients remain high and comparable to bare ice for the investigated systems. We conclude that impurities can either enhance or restrict water uptake in ways that are influenced by several factors including temperature and type of adsorbant, with potential implications for the description of ice particle growth in the atmosphere. This work was supported by the Swedish Research Council and

  19. Practice.

    Chambers, David W

    2008-01-01

    Practice refers to a characteristic way professionals use common standards to customize solutions to a range of problems. Practice includes (a) standards for outcomes and processes that are shared with one's colleagues, (b) a rich repertoire of skills grounded in diagnostic acumen, (c) an ability to see the actual and the ideal and work back and forth between them, (d) functional artistry, and (e) learning by doing that transcends scientific rationality. Communities of practice, such as dental offices, are small groups that work together in interlocking roles to achieve these ends. PMID:19413050

  20. Public housing accommodations for individuals with disabilities.

    Little, Samuel B

    2002-01-01

    The federal Housing Act of 1962 as amended and the subsequent laws of accommodations insure that all groups within American society, including those with disabilities, have access to housing opportunities. In spite of the clear provisions of various laws of accommodations enacted after 1962, it is questionable whether disabled individuals are adequately served by resident programs operated by Public Housing Agencies (PHAs) because rates of poverty, unemployment, domestic violence, and suicide are much higher among people with disabilities than in the nondisabled population. There are approximately 5 million residents living in 2.5 public housing units nationwide. New York, Puerto Rico, Chicago, Philadelphia and Baltimore have the five largest PHAs in the country. In combination, they rent 320,000 of the 1,300,495 inventory of rental properties owned by the country's 3,400 PHAs. Elderly and disabled residents without children account for 43% of all public housing families in the country. PMID:12809381

  1. Accommodation processes during deformation of nanocrystalline palladium

    Atomistic simulations of uniaxial tensile and compressive straining of three-dimensional nanocrystalline palladium were performed at room temperature and different strain rates. Detailed analysis revealed that initial plastic deformation is due to grain boundary sliding accommodated by localized bending inside the grains and the formation of dislocation embryos. Intergranular cracking in the absence of dislocation activity was found at later stages of tensile straining. During compressive straining the sample shows a plastic response which is brought about mainly by intergranular accommodation processes. The contribution of extended partial dislocations emitted from the grain boundaries as well as full dislocations and twinning at later stages of deformation to the total strain was found to be insignificant.

    Currently, attempts at surgical correction of presbyopia (with or without simultaneous cataract surgery) are receiving considerable attention. Different approaches to presbyopia correction can be chosen. It is generally believed that hardening of the lens substance contributes to the development of presbyopia. In order to restore accommodation, we have chosen an approach in which the hardened lens substance is removed through a small opening in the lens capsule and the lens contents is replac...

    随着我国风电装机容量的不断增长,风电接入能力成为制约其发展的瓶颈。供暖期实行“以热定电”的运行模式,热电机组的调峰能力受到供热出力水平的限制,影响了风电的消纳。因而,突破这一传统模式,形成电力系统与热力系统的协调优化运行,是缓解弃风问题的关键。该文充分考虑电源与热源的复杂性、热力系统的网络约束等因素的影响,首先建立了适用于电热能源集成系统分析的热力网络模型,并在此基础上建立了考虑热力网络约束及火电机组启停的电热能源集成系统运行优化模型。利用该模型研究了电热协调运行方式对风电消纳的促进作用,并分析了输送容量限制、输送延时、输送损耗等热网约束条件对系统运行结果的影响。%With the continuous growth of the installed capacity of wind power in China, the ability of integrating wind power becomes the bottleneck of its development. The electricity generation is determined by the heat supply in the heating period, so that the peak shaving capacity of the combined heat and power (CHP) units is limited by the heat demand, which restricts the wind power integration. Breaking this traditional operation mechanism and interacting the power system with the heating system is the key to alleviate the problem of wind power curtailment. This paper considered the heating network constraints and built up the model of the heating network which could be used in integrated energy systems. Based on it, an operation optimization model of the integrated power and heat energy systems which considered the heating network constraints and thermal unit commitment was proposed. Using this model, this paper proved that coordination the power system with the heating system could play an active role in the promotion of wind power integration.Besides, the impacts of the transmission capacity, the transmission delay and the

  8. MULTIDISCIPLINARY APPROACH TO THE CORRECTION OF ACCOMMODATION REFRACTION DISORDERS IN VISUALLY INTENSIVE LABOR PERSONS

    I. G. Ovechkin

    2015-01-01

    Full Text Available Increased load on the visual analyzer of an operator, increase in everyday visual performance, universal introduction of information displaying on cathode-ray tubes result in temporary and stable visual disturbances. Accommodative refractive apparatus of an eye is one of the key points of application of visually intensive labor. Work associated with permanent eyestrain overloads oculomotor and accommodative apparatus thus provoking myopic shift, increase in dynamic refraction, exophoric or esophoric shift of initial visual equilibrium. Accommodation disorders are accompanied by changes in ciliary muscle blood supply, abnormalities of vegetative segment regulation, parasympathetic brain vascular dystonia due to the decreased tonus of sympathetic nervous system. Evaluation of certain kind of activity in terms of ergonomics includes examination of visual status and visual working capacity, development of visual professiograms and vision standards for certain professions, justification of methods and tools of visual work optimization. Visual disturbances in operators developing in the course of visually intensive occupational work should be considered from the viewpoint of traditional accommodation and refraction disorders as well as functional manifestations of general fatigue or thoracic cervical spine dysfunction. Symptoms of accommodative asthenopia can be regarded as a functional manifestation of general fatigue syndrome or functional neurosis. Development of multidisciplinary approach to the correction of accommodation refraction disorders in visually intensive labor persons is of scientific urgency and practical reasonability. There is a long-felt need in additional attraction of different specialists who use in their work physical factors for accommodative asthenopia correction. Development of multidisciplinary approach to accommodation refraction disorder correction in visually intensive labor persons is based on syndromic pathogenic

  14. ACCOMMODATION PREFERENCES OF FOREIGN TOURISTS IN ROMANIA

    Ionela Mituko VLAD

    2014-04-01

    Full Text Available The present work is a study on indicators that define tourism in Romania. Analysis focused on indicators of the number of tourists and tourist arrivals in accommodation establishments in Romania, in total and in agro-touristic boarding houses on four macro-administrative units and by category of comfort in our country. The methodology used to track the preferences of foreign tourists in accommodation establishments in Romania was to analyse the dynamics of the mentioned indicators, the seasonality of arrivals and forecasting the arrivals of foreign tourists. The data used are from the Statistical Yearbook of Romania, covering the period 2010-2013; some of them are quarterly data. The results have indicated a preference of the arrivals especially in Q3 of each year, in macro-regions M3 and M1, for foreigners and in the macro-regions M1 and M2 for the Romanian tourists. Another results designed the preferences of tourists related to the degree of comfort, which has decreased in time with the increasing levels of comfort; over time, the tourist’s number increases on the total from year to year; in particular, in the agro hostels this number is growing slowly.

  15. The child sexual abuse accommodation syndrome.

    Summit, R C

    1983-01-01

    Child victims of sexual abuse face secondary trauma in the crisis of discovery. Their attempts to reconcile their private experiences with the realities of the outer world are assaulted by the disbelief, blame and rejection they experience from adults. The normal coping behavior of the child contradicts the entrenched beliefs and expectations typically held by adults, stigmatizing the child with charges of lying, manipulating or imagining from parents, courts and clinicians. Such abandonment by the very adults most crucial to the child's protection and recovery drives the child deeper into self-blame, self-hate, alienation and revictimization. In contrast, the advocacy of an empathic clinician within a supportive treatment network can provide vital credibility and endorsement for the child. Evaluation of the responses of normal children to sexual assault provides clear evidence that societal definitions of "normal" victim behavior are inappropriate and procrustean, serving adults as mythic insulators against the child's pain. Within this climate of prejudice, the sequential survival options available to the victim further alienate the child from any hope of outside credibility or acceptance. Ironically, the child's inevitable choice of the "wrong" options reinforces and perpetuates the prejudicial myths. The most typical reactions of children are classified in this paper as the child sexual abuse accommodation syndrome. The syndrome is composed of five categories, of which two define basic childhood vulnerability and three are sequentially contingent on sexual assault: (1) secrecy, (2) helplessness, (3) entrapment and accommodation, (4) delayed, unconvincing disclosure, and (5) retraction. The accommodation syndrome is proposed as a simple and logical model for use by clinicians to improve understanding and acceptance of the child's position in the complex and controversial dynamics of sexual victimization. Application of the syndrome tends to challenge entrenched

  16. The interactive processes of accommodation and vergence.

    Semmlow, J L; Bérard, P V; Vercher, J L; Putteman, A; Gauthier, G M

    1994-01-01

    A near target generates two different, though related stimuli: image disparity and image blur. Fixation of that near target evokes three motor responses: the so-called oculomotor "near triad". It has long been known that both disparity and blur stimuli are each capable of independently generating all three responses, and a recent theory of near triad control (the Dual Interactive Theory) describes how these stimulus components normally work together in the aid of near vision. However, this theory also indicates that when the system becomes unbalanced, as in high AC/A ratios of some accommodative esotropes, the two components will become antagonistic. In this situation, the interaction between the blur and disparity driven components exaggerates the imbalance created in the vergence motor output. Conversely, there is enhanced restoration when the AC/A ratio is effectively reduced surgically. PMID:7633627

  17. FDI and Accommodation Using NN Based Techniques

    Garcia, Ramon Ferreiro; de Miguel Catoira, Alberto; Sanz, Beatriz Ferreiro

    Massive application of dynamic backpropagation neural networks is used on closed loop control FDI (fault detection and isolation) tasks. The process dynamics is mapped by means of a trained backpropagation NN to be applied on residual generation. Process supervision is then applied to discriminate faults on process sensors, and process plant parameters. A rule based expert system is used to implement the decision making task and the corresponding solution in terms of faults accommodation and/or reconfiguration. Results show an efficient and robust FDI system which could be used as the core of an SCADA or alternatively as a complement supervision tool operating in parallel with the SCADA when applied on a heat exchanger.

  18. Biomimetic accommodating lens with implementation in MEMS

    Hogan, Alexander L.; Baker, Brian; Fisher, Charles; Naylor, Stephen; Fettig, Doug; Harvey, Ian R.

    2012-03-01

    We describe an accommodating lens patterned after the crystalline lens of the eye. Our biomimetic MEMS design calls to mind the zonules of zinn which pull radially to stretch the crystalline lens of the eye to modify the optical path. We present initial characterization of the prototype macro-scale device constructed through traditional machining techniques and using a PDMS polymer lens. Testing of the macro-scale lens indicated a 22% change in focal length through the range of radial stretching, with degradation of the spherical lens shape but no hysteresis after low-cycle testing. We also demonstrate a MEMS implementation of the lens actuator constructed using the Sandia SUMMiT-V ™ surface micromachining process. The optical path of this system is approximately 300 microns in diameter, providing a platform to potential applications improving mobile camera optics and medical imaging.

  3. Restoration of accommodation: surgical options for correction of presbyopia

    Glasser, Adrian

    2008-01-01

    Accommodation is a dioptric change in the power of the eye to see clearly at near. Ciliary muscle contraction causes a release in zonular tension at the lens equator, which permits the elastic capsule to mould the young lens into an accommodated form. Presbyopia, the gradual age-related loss of accommodation, occurs primarily through a gradual age-related stiffening of the lens. While there are many possible options for relieving the symptoms of presbyopia, only relatively recently has consid...

    Long, Erping; Lin, Haotian

    2015-09-01

    Accommodation is an important function of the human eye, which can change the parameters of ocular refractive system and also has a strong correlation with the development of myopia and presbyopia. Several subjective measurements have been applied in accommodation assessment such as push-up test, push-down test and minus-lens procedures. It can be measured objectively by measuring the change in refraction of the eye with dynamic retinoscopy or autorefractor. This article reviews the application of measurement of accommodative amplitude and research progress in accommodation, providing clinical information for further studies. PMID:26930838

  13. Cultural value orientations, internalized homophobia, and accommodation in romantic relationships.

    Gaines, Stanley O; Henderson, Michael C; Kim, Mary; Gilstrap, Samuel; Yi, Jennifer; Rusbult, Caryl E; Hardin, Deletha P; Gaertner, Lowell

    2005-01-01

    In the present study, we examined the impact of cultural value orientations (i.e., the personally oriented value of individualism, and the socially oriented values of collectivism, familism, romanticism, and spiritualism) on accommodation (i.e., voice and loyalty, rather than exit and neglect, responses to partners' anger or criticism) in heterosexual and gay relationships; and we examined the impact of internalized homophobia (i.e., attitudes toward self, other, and disclosure) on accommodation specifically in gay relationships. A total of 262 heterosexuals (102 men and 162 women) and 857 gays (474 men and 383 women) participated in the present study. Consistent with hypotheses, among heterosexuals and gays, socially oriented values were significantly and positively related to accommodation (whereas the personally oriented value of individualism was unrelated to accommodation); and among gays in particular, internalized homophobia was significantly and negatively related to accommodation. Implications for the study of heterosexual and gay relationships are discussed. PMID:16368666

    thermoregulation, muscular, and cardiac responses to weightlessness. In contrast, the five completed Cosmos/Bion flights, lacked the metabolic samples and behavioral task monitoring, but did facilitate studies of the neurovestibular system during several of the flights. The RRF accommodated two adult 8-11 kg rhesus monkeys, while the Russian experiments and hardware were configured for a younger animal in the 44 kg range. Both the American and Russian hardware maintained a controlled environmental system, specifically temperature, humidity, a timed lighting cycle, and had means for providing food and fluids to the animal(s). Crew availability during a Shuttle mission was to be an optimal condition for retrieval and refrigeration of the animal urine samples along with a manual calcein injection which could lead to greater understanding of bone calcium incorporation. A special portable bioisolation glove box was under development to support this aspect of the experiment profile along with the capability of any contingency human intervention. As a result of recent U.S./Russian negotiations, funding for Space Station, and a series of other events, the SLS-3 mission was cancelled and applicable Rhesus Project experiments incorporated into the Russian Bion 11 and 12 missions. A presentation of the RRF and COSMOS/Bion rhesus hardware is presented along with current plans for the hardware.

  18. Private university accommodation: developmentscenarios and critical success factors

    Maria Luisa Del Gatto

    2012-10-01

    Full Text Available The number of students looking for accommodation away from home is increasing significantly. Many countries have demonstrated their ability in responding to this demand with university accommodation initiatives. Italy has taken action a little late and with some discrepancies, on the one hand trying to attract foreign students while on the other neglecting the provision of services and hospitality. This study investigates the elements that contribute to determining the feasibility and economic/financial balance of private investment in the university accommodation sector, illustrating the possible development scenarios in our country and considering previous experience, through the identification of some critical success factors.

  19. Treatment of Accommodative and Vergence Dysfunction in Traumatic Brain Injury (TBI: A Case Report

    Anna Griffith, OD

    2015-06-01

    Full Text Available Background: Accommodative insufficiency (AI, accommodative infacility, and convergence insufficiency (CI are some of the most common visual problems following traumatic brain injury (TBI. In light of the increased prevalence of TBIs in modern-day combat, it is important for clinicians to be aware of the associated visual symptoms and methods of treatment. The mechanism of progressive neural damage in TBI as well as the neural-anatomical pathways of accommodation and vergence will be reviewed in the case report presented here. Important considerations when treating patients with TBI will also be discussed. Case Report: This case report describes the diagnosis, management, and treatment of accommodative and vergence dysfunction in a 33-year-old veteran with a history of multiple TBIs incurred during combat in Afghanistan. The veteran was diagnosed with asymmetric accommodative insufficiency and infacility and gross convergence insufficiency, and he had decreased depth perception. Five in-office vision therapy sessions were conducted over the course of a month and a half, with daily practice at home, followed by maintenance activities and tapering of vision training. Treatment restored the patient’s visual clarity, comfort, and fine stereopsis, enabling him to pursue his goal of returning to school for engineering. Conclusion: Vision therapy improves visual function and symptoms from TBI in many patients. An increase in TBI due to modern-day warfare has increased the awareness of and the need for recognition and treatment of visual problems. Most, if not all, communities have a need for vision care for patients with TBI from car crashes, accidents, sports injuries, and concussion. Prompt diagnosis and treatment of visual dysfunction is critical to improving quality of life, ability to work towards vocational goals, and progress of other rehabilitation therapies which require varied visual tasks.

  20. The Balance Between Coercion and Accommodation

    @@ 1. Introduction On the morning of April 1st, 2001, a U.S. EP-3 surveillance aircraft was conducting an intelligence flight along the Chinese territorial border in the airspace south-east of China's Hainan Island. Two Chinese fighter jets intercepted the spy plane and followed its flight, as is considered ordinary international practice. For reasons unknown, the EP-3 airplane made a sudden maneuver and crashed into one of the Chinese planes. The Chinese plane dropped into the sea, the pilot missing. The U.S. spy plane was also severely damaged. It intruded into Chinese territorial space and landed on Hainan Island without official permission from the Chinese side.After landing, the spy plane and 24 crew on board were detained by the Chinese authorities. This air collision episode was the first of its kind in the China-U.S. relations and an urgent diplomatic crisis ensued.

  1. On cloud modelling and the mass accommodation coefficient of water

    A. Laaksonen

    2004-11-01

    Full Text Available The mass accommodation coefficient of water is a quantity for which different experimental techniques have yielded conflicting values in the range 0.04–1. From the viewpoint of cloud modelling, this is an unfortunate situation, since the value of the mass accommodation coefficient affects the model results, e.g. the number concentration of activated cloud droplets. In this paper we argue that a mass accommodation coefficient of unity should be used in cloud modelling, since this value has been obtained in experimental studies of water droplet growth rates, a quantity which is explicitly described in cloud models. In contrast, mass accommodation coefficient values below unity have been derived from experimental results which are analyzed with different theoretical expressions than those included in cloud models.

  2. Amplitude of Accommodation and its Relation to Refractive Errors

    2009-01-01

    Background: Clinical measurement of the amplitude of accommodation (AA) provides an indication of maximum accommodative ability. To determine whether there has been a significant change in the AA, it is important to have a good idea of the repeatability of the measurement method used. The aim of the present study was to compare AA measurements made using three different subjective clinical methods: the push-up, push-down, and minus lens techniques. These methods differ in terms of the apparen...

  5. Single-optic positional accommodating intraocular lenses: a review

    Tomás Juan, Javier; Piñero Llorens, David Pablo; Larrañaga Murueta-Goyena, Ane

    2014-01-01

    Presbyopia is an age-related physiological condition that causes a gradual loss in the ability to focus on near objects, secondary to changes in zonular fibers, ciliary muscle and crystalline lens. Different surgical approaches are being pursued to surgically compensate presbyopia, such as corneal techniques or implantation of multifocal intraocular lenses (IOLs); however, their inability to restore accommodation has led to the development of single-optic positional accommodative IOLs. The ax...

  11. Memoization of Coroutined Constraints

    Johnson, M; Johnson, Mark; Dörre, Jochen

    1995-01-01

    Some linguistic constraints cannot be effectively resolved during parsing at the location in which they are most naturally introduced. This paper shows how constraints can be propagated in a memoizing parser (such as a chart parser) in much the same way that variable bindings are, providing a general treatment of constraint coroutining in memoization. Prolog code for a simple application of our technique to Bouma and van Noord's (1994) categorial grammar analysis of Dutch is provided.

Our system incorporates as a very basic, all the existing systems incorporating constraints i...

  13. Constraints on Anaphoric Determiners

    Zuber, Richard

    2010-01-01

    Some constraints on functions from sets and relations to sets are studied. Such constraints are satisfied by anaphoric functions, that is functions denoted by anaphoric determiners. These constraints are generalisations of anaphor conditions known from the study of simpler cases of nominal anaphors. In addition a generalisation of the notion of conservativity as applied to anaphoric functions is proposed. Two classes of anaphoric determiners found in NLs are discussed as examples.

  15. Reasonable Accommodation In The Workplace: To Be Or Not To Be?

    Rowena Bronwen Bernard

    2014-12-01

    Full Text Available Freedom of religion is a fundamental right enshrined in and protected by section 15 of the Constitution. This right allows for the practice of religion without interference from the state and individuals. A question which often arises relates to the extent to which freedom of religion can be exercised in the workplace. Religious practice often extends beyond societal norms, but religious intolerance has proven to be a source of conflict. In the workplace this conflict arises "where the employer's right to the employee's labour and service conflicts with the employee's inability or refusal to render services because of a religious or cultural belief". The courts have played an important role in balancing the rights of the employer to manage his business operations efficiently with the rights of the employee to practice his religious or cultural beliefs. The critical question is how the employer is expected to balance and maintain an orderly, disciplined and efficient workplace whilst accommodating an employee's right to religious freedom. The case of Department of Correctional Services v Police and Prison Civil Rights Union (POPCRU 2011 32 ILJ 2629 (LAC is one where the employer's application of rules relating to the dress code of employees impacted on the religious beliefs and practices of five staff. In this note, this decision and the decisions in other recent cases are analysed in order to determine how the courts have dealt with the issue of the reasonable accommodation of religious practices in the workplace. The employer in the POPCRU case was justified in wanting to improve the discipline and standards within the prison. The findings of the LAC and SCA were indeed correct: while the dress code appeared to be neutral, the actual impact resulted in the disparate treatment of the employees. They were discriminated against as a result of wearing dreadlocks. The employer failed to reasonably accommodate the religious beliefs of the employees

  16. An Isotropic SPPP Mo del for Femto cells Networks with Outage Probability Constraints

    ZHANG Jun; TIAN Hui

    2015-01-01

    Femtocells have been considered as a cost-eff ective solution to unload traffic from already overbur-dened macrocell networks in 4G cellular networks. The severe interference in spectrum-sharing macro and femto networks may cause User-equipment (UE) to experience outage. We derive an utmost isotropic Spatial Poisson point process (SPPP) density for Femtocell access points (FAPs) under the UEs’ outage constraints. Based on the derived isotropic SPPP density, we propose a distributed transmit probability self-regulation scheme for an FAP to adapt its transmit probability per Transmission time in-terval (TTI). The scheme adjusts the homogeneous dis-tributed FAPs in practice deployment to the proposed isotropic one. Simulation results show that the derived den-sity can fulfill the outage probability constraints of UEs while accommodating the maximum femtocells. The self-regulation scheme can adapt the femtocell transmit prob-abilities to provide reliable downlink service, for even a large number of femtocells per cell site.

  17. Optimal charging method for lithium ion batteries using a universal voltage protocol accommodating aging

    Guo, Zhen; Liaw, Bor Yann; Qiu, Xinping; Gao, Lanlan; Zhang, Changshui

    2015-01-01

    An effective optimum charging technique for lithium ion batteries using a universal voltage protocol (UVP) that can accommodate cell aging is presented here. This charging method demands less learning to varying state-of-health (SOH) conditions with potential to improve charging efficiency and cycle life. The simplicity of UVP makes the implementation easier than the conventional constant current-constant voltage (CC-CV)-based methods. Here, the mathematical formulation, optimization targets (e.g. minimal time) and constraints (terminal voltages and other instrumental and cell electrochemistry-limited ones) are explained from the protocol design considerations. An equivalent circuit model was used and its parameters derived from the analysis of test data, which could yield a nonlinear varying current profile (VCP) by simulation and a genetic algorithm-based optimization. Both UVP and VCP were used in the validation to illustrate better charging efficiency and capacity retention, which showed a much improved cycle life.

  18. Accommodating Uncertainty in ADAS Models and Data

    The Atomic Data and Analysis Structure (ADAS) is an interconnected set of computer codes and data collections for modelling the radiating properties of ions and atoms in plasmas and for assisting in the analysis and interpretation of spectral measurements. Fundamental atomic data is mediated via collisional-radiative population models to produce the effective coefficients for practical use in impurity transport modelling, influx estimation, beam stopping efficiency and active charge exchange quantification. Away from the coronal picture, the simple connection between fundamental processes and the derived population or emissivity is lost. Instead these coefficients become dependent on many fundamental processes with unknown weightings. The challenge is threefold: to develop methods for assigning an uncertainty to the fundamental data, to propagate these through the population models and to enable techniques to utilize within plasmas models atomic data that comes with an accompanying error surface. Pure atomic properties, such as energy levels and some transition probabilities, are measurable and are known to high precision. However most of the fundamental data required for fusion work, such as excitation and state selective charge transfer cross sections, ionisation and recombination rates (for both electron and ion drivers) remain the result of theoretical calculations and this is not likely to change. The envelope of variation between different methods and calculations is the simplest approach to ascribing an error and is useful in identifying both the principal contributors to the final quantity of interest and to assess its domain of influence. A more refined approach, based on variation of the control parameters of the fundamental ab initio codes, is adopted for this smaller set of significant cross sections. The error for the derived quantities is computed via a statistical sampling methodology assuming an error distribution within the ascribed uncertainty

  19. Relative Importance of Student Accommodation Quality in Higher Education

    Simon Gyasi Nimako

    2013-07-01

    Full Text Available This study, which was part of a large study, empirically examinesthe importance students attach to different dimensions of Student Accommodation Quality (SAQ delivered by Student Accommodation Providers (SAP in two tertiary (higher education institutions in Ghana. The study involved a cross-sectional survey that used a structured questionnaire administered to 700 tertiary students in residential and non-residential accommodation. The survey yielded a usable 66.6% response rate for analysis. The findings indicate that utility facility quality is the most important SAQ dimension to the students, followed by the overall impression of hostel, security, physical environment, toilet, distance to lecture, bedroom, bath room, accommodation fee, among others. Moreover, it was found that kitchen facility, access to transport and entertainment facility are less important SAQ items while the least important is garage facility. Few differences were found in the priority for SAQ items between COLTEK and K-Poly respondents and between residential and non-residential respondents. Implications for theory and recommendations to management of the two higher education institutions and SAP have been discussed. The study contributes to the body of knowledge in student affairs and managing student accommodation quality in higher education.

  20. Accommodating Autistics and Treating Autism: Can We Have Both?

    Lim, Chong-Ming

    2015-10-01

    One of the central claims of the neurodiversity movement is that society should accommodate the needs of autistics, rather than try to treat autism. People have variously tried to reject this accommodation thesis as applicable to all autistics. One instance is Pier Jaarsma and Stellan Welin, who argue that the thesis should apply to some but not all autistics. They do so via separating autistics into high- and low-functioning, on the basis of IQ and social effectiveness or functionings. I reject their grounds for separating autistics. IQ is an irrelevant basis for separating autistics. Charitably rendering it as referring to more general capacities still leaves us mistaken about the roles they play in supporting the accommodation thesis. The appeal to social effectiveness or functionings relies on standards that are inapplicable to autistics, and which risks being deaf to the point of their claims. I then consider if their remaining argument concerning autistic culture may succeed independently of the line they draw. I argue that construing autistics' claims as beginning from culture mistakes their status, and may even detract from their aims. Via my discussion of Jaarsma and Welin, I hope to point to why the more general strategy of separating autistics, in response to the accommodation thesis, does not fully succeed. Finally, I sketch some directions for future discussions, arguing that we should instead shift our attention to consider another set of questions concerning the costs and extent of change required to accommodate all autistics.

  1. Podcasts on Mobile Devices as a Read-Aloud Testing Accommodation in Middle School Science Assessment

    McMahon, Don; Wright, Rachel; Cihak, David F.; Moore, Tara C.; Lamb, Richard

    2016-04-01

    The purpose of this study was to examine the effect of a digitized podcast to deliver read-aloud testing accommodations on mobile devices to students with disabilities and reading difficulties. The total sample for this study included 47 middle school students with reading difficulties. Of the 47 students, 16 were identified as students with disabilities who received special education services. Participants were randomly assigned to three experimental testing conditions, standard administration, teacher-controlled read-aloud in traditional group delivery format, and student-controlled read-aloud delivered as a podcast and accessed on a mobile device, and given sample end-of-year science assessments. Based on a factorial analysis of variances, with test conditions and student status as the fixed factors, both student groups demonstrated statistically significant gains based on their testing conditions. Results support the use of podcast delivery as a viable alternative to the traditional teacher-delivered read-aloud test accommodation. Conclusions are discussed in the context of universal design for learning testing accommodations for future research and practice.

  10. Accommodative response and cortical activity during sustained attention.

    Poltavski, Dmitri V; Biberdorf, David; Petros, Thomas V

    2012-06-15

    Greater accommodative lag and vergence deficits have been linked to attentional deficits similar to those observed in Attention Deficit Hyperactivity Disorder (ADHD). The purpose of the present study was to assess the effect of accommodative-vergence stress on a measure of sustained attention (Conners CPT) used in the diagnosis of ADHD. Twenty-seven normal non-ADHD adults completed the Conners CPT twice: wearing -2.00 D lenses and normally (without the -2.00 D lenses) in a counterbalanced order with at least 24 h between the sessions. Simultaneous recording of participants' dynamic accommodative responses was performed from the right eye using the Grand Seiko WAM-5500 auto-refractor and electroencephalographic activity (EEG) in the left prefrontal region using the Neurosky Mindset headset. The results demonstrated a significantly greater accommodative lag in the -2.00 D stress condition and a significantly poorer performance on the Conners CPT as indexed by slower reaction time, greater standard error of hit reaction time, grater response variability, poorer stimulus detectability and a greater number of perseverations. No differences were observed on measures of EEG in the theta (4-7 Hz), alpha (8-12 Hz), and beta (12-20 Hz) bands. Moreover, when directly juxtaposed with each EEG band in multiple linear regression analyses, greater accommodative lag in the stress condition was significantly associated with a greater probability of clinical classification on the Conners CPT, and was also marginally predictive of the number of omissions recorded in the stress condition. The results demonstrated that sustained attention can be influenced by such factors as accommodative-vergence stress and suggest that bottom-up processes can contribute to and potentially exacerbate attentional problems in individuals with ADHD. The study also showed that cortical dysfunction (while sufficient) may not be a necessary condition for attentional deficits. PMID:22580016

    An SRI dual Purkinje image (dPi) eye tracker was used to measure lens wobble following saccades with increasing accommodative effort as an indirect measure of ciliary muscle function in presbyopes. Ten presbyopic subjects executed 32 four-degree saccades at 1-s intervals between targets arranged in a cross on illuminated cards at each of 9 viewing distances ranging from 0.5- to 8-D accommodative demands. Post-saccadic lens wobble artifacts were extracted by subtraction of P1 (H1/V1) position ...

  12. The accommodative ciliary muscle function is preserved in older humans

    Tabernero, Juan; Chirre, Emmanuel; Hervella, Lucia; Prieto, Pedro; Artal, Pablo

    2016-01-01

    Presbyopia, the loss of the eye’s accommodation capability, affects all humans aged above 45–50 years old. The two main reasons for this to happen are a hardening of the crystalline lens and a reduction of the ciliary muscle functionality with age. While there seems to be at least some partial accommodating functionality of the ciliary muscle at early presbyopic ages, it is not yet clear whether the muscle is still active at more advanced ages. Previous techniques used to visualize the accomm...

  15. Constraint-based reachability

    Arnaud Gotlieb

    2013-02-01

    Full Text Available Iterative imperative programs can be considered as infinite-state systems computing over possibly unbounded domains. Studying reachability in these systems is challenging as it requires to deal with an infinite number of states with standard backward or forward exploration strategies. An approach that we call Constraint-based reachability, is proposed to address reachability problems by exploring program states using a constraint model of the whole program. The keypoint of the approach is to interpret imperative constructions such as conditionals, loops, array and memory manipulations with the fundamental notion of constraint over a computational domain. By combining constraint filtering and abstraction techniques, Constraint-based reachability is able to solve reachability problems which are usually outside the scope of backward or forward exploration strategies. This paper proposes an interpretation of classical filtering consistencies used in Constraint Programming as abstract domain computations, and shows how this approach can be used to produce a constraint solver that efficiently generates solutions for reachability problems that are unsolvable by other approaches.

  16. Kernels for Global Constraints

    Gaspers, Serge

    2011-01-01

    Bessiere et al. (AAAI'08) showed that several intractable global constraints can be efficiently propagated when certain natural problem parameters are small. In particular, the complete propagation of a global constraint is fixed-parameter tractable in k - the number of holes in domains - whenever bound consistency can be enforced in polynomial time; this applies to the global constraints AtMost-NValue and Extended Global Cardinality (EGC). In this paper we extend this line of research and introduce the concept of reduction to a problem kernel, a key concept of parameterized complexity, to the field of global constraints. In particular, we show that the consistency problem for AtMost-NValue constraints admits a linear time reduction to an equivalent instance on O(k^2) variables and domain values. This small kernel can be used to speed up the complete propagation of NValue constraints. We contrast this result by showing that the consistency problem for EGC constraints does not admit a reduction to a polynomial...

  17. Constraints on dark matter particles charged under a hidden gauge group from primordial black holes

    Dai, De-Chang; Freese, Katherine; Stojkovic, Dejan

    2009-01-01

    In order to accommodate increasingly tighter observational constraints on dark matter, several models have been proposed recently in which dark matter particles are charged under some hidden gauge group. Hidden gauge charges are invisible for the standard model particles, hence such scenarios are very difficult to constrain directly. However black holes are sensitive to all gauge charges, whether they belong to the standard model or not. Here, we examine the constraints on the possible values...

  20. Analysis and applications of accommodative lenses for vision corrections.

    Lin, Jui-Teng; Jiang, Minshan; Chang, Chun-Lin; Hong, Yu-Ling; Ren, Qiushi

    2011-01-01

    Analysis and applications of vision correction via accommodating intraocular lens (AIOL) are presented. By Gaussian optics, analytic formulas for the accommodation rate function (M) for two-optics and three-optics systems are derived and compared with the exact numerical results. In a single-optics AIOL, typical value of M is (0.5-1.5) D∕mm, for an IOL power of (10-20) diopter. For a given IOL power, higher M is achieved in positive-IOL than negative-IOL. In the dual-optics AIOL, maximum accommodation is predicted when the front positive-optics moves toward the corneal plan and the back negative-optics moves backward. Our analytic formulas predict that greater accommodative rate may be achieved by using a positive-powered front optics, a general feature when either front or back optics is mobile. The M function is used to find the piggy-back IOL power for customized design based on the individual ocular parameters. Many of the new features demonstrated in this study can be easily realized by our analytic formulas, but not by raytracing method. PMID:21280927

  3. The accommodative ciliary muscle function is preserved in older humans.

    Tabernero, Juan; Chirre, Emmanuel; Hervella, Lucia; Prieto, Pedro; Artal, Pablo

    2016-01-01

    Presbyopia, the loss of the eye's accommodation capability, affects all humans aged above 45-50 years old. The two main reasons for this to happen are a hardening of the crystalline lens and a reduction of the ciliary muscle functionality with age. While there seems to be at least some partial accommodating functionality of the ciliary muscle at early presbyopic ages, it is not yet clear whether the muscle is still active at more advanced ages. Previous techniques used to visualize the accommodation mechanism of the ciliary muscle are complicated to apply in the older subjects, as they typically require fixation stability during long measurement times and/or to have an ultrasound probe directly in contact with the eye. Instead, we used our own developed method based on high-speed recording of lens wobbling to study the ciliary muscle activity in a small group of pseudophakic subjects (around 80 years old). There was a significant activity of the muscle, clearly able to contract under binocular stimulation of accommodation. This supports a purely lenticular-based theory of presbyopia and it might stimulate the search for new solutions to presbyopia by making use of the remaining contraction force still presented in the aging eye.

  3. Accommodating environmental variation in population models: metaphysiological biomass loss accounting.

    Owen-Smith, Norman

    2011-07-01

    1. There is a pressing need for population models that can reliably predict responses to changing environmental conditions and diagnose the causes of variation in abundance in space as well as through time. In this 'how to' article, it is outlined how standard population models can be modified to accommodate environmental variation in a heuristically conducive way. This approach is based on metaphysiological modelling concepts linking populations within food web contexts and underlying behaviour governing resource selection. Using population biomass as the currency, population changes can be considered at fine temporal scales taking into account seasonal variation. Density feedbacks are generated through the seasonal depression of resources even in the absence of interference competition. 2. Examples described include (i) metaphysiological modifications of Lotka-Volterra equations for coupled consumer-resource dynamics, accommodating seasonal variation in resource quality as well as availability, resource-dependent mortality and additive predation, (ii) spatial variation in habitat suitability evident from the population abundance attained, taking into account resource heterogeneity and consumer choice using empirical data, (iii) accommodating population structure through the variable sensitivity of life-history stages to resource deficiencies, affecting susceptibility to oscillatory dynamics and (iv) expansion of density-dependent equations to accommodate various biomass losses reducing population growth rate below its potential, including reductions in reproductive outputs. Supporting computational code and parameter values are provided. 3. The essential features of metaphysiological population models include (i) the biomass currency enabling within-year dynamics to be represented appropriately, (ii) distinguishing various processes reducing population growth below its potential, (iii) structural consistency in the representation of interacting populations and

  5. Istanbul hotels from a 360 0 perspective: A comprehensive view of the Istanbul accommodation industry

    Maria D. Alvarez

    2012-03-01

    Full Text Available As destinations are striving to become more competitive and attract visitors and tourists, the performance of its enterprises, including hotels is essential. Despite the significance of research in this area, to date, there are no studies that analyze the accommodation industry of a given destination from a broad perspective, since most of the investigations focus on a specific area of the organization and its relationship with the hotel’s performance. Therefore, the research aims to provide a comprehensive view of the accommodation industry in Istanbul. Moreover, the study will also attempt to establish a standard data collection instrument that can be used in the future as a benchmarking tool. The research will be carried out on a number of complementary perspectives that include management practices, financial performance measures, operational indicators, employee profile and attitudes, customer profile and satisfaction, environmental practices and use and investment in technology. Furthermore, the study attempts to determine the most important factors that affect the performance of the hotels and to explore the relationship between the different variables included.

  7. Ex vivo accommodation simulator II: concept and preliminary results

    Ehrmann, Klaus; Ho, Arthur; Parel, Jean-Marie

    2004-07-01

    A new instrument was developed to simulate the accommodation of excised human and animal crystalline lenses. The sclera is attached to 8 radially arranged translation stages and dissected into 8 segments. Change in accommodation is simulated by pulling and releasing the scleral segments, varying the load on the zonules and the capsular bag. Each translation stage is equipped with a sensitive force transducer for simultaneous recording of load and displacement. Additionally, changes in optical power, lens diameter, lens thickness and lens shape can be observed and quantified while the lens is stretched and released. The sensitivity and accuracy of the instrument was verified using steel springs and elastic bands. Preliminary results from sensitivity testing and instrument calibration are presented.

  9. CHOA concussion consensus: establishing a uniform policy for academic accommodations.

    Popoli, David Michael; Burns, Thomas G; Meehan, William P; Reisner, Andrew

    2014-03-01

    Concussion research generally centers on physical challenges, though aspects such as social functioning and returning to school also warrant attention in pediatric populations. Restoring academic performance postconcussion remains a challenge. Here we provide recommendations addressing a uniform policy for pediatric concussion patients in academic institutions. Tools that may minimize difficulty with academic re-entry include independent educational evaluations, individualized educational programs (IEPs), student support teams (SSTs), letters of academic accommodation, time off, and 504 Plans. Recognition and treatment is crucial for symptom relief and prevention of functional disruption, as is specialist referral during the acute window. We recommend early intervention with a letter of academic accommodation and SST and suggest that 504 Plans and IEPs be reserved for protracted or medically complicated cases. Students with concussion should be observed for anxiety and depression because these symptoms can lead to prolonged recovery, decreased quality of life, and other social challenges. PMID:23960266

  10. Psychological constraints on egalitarianism

    Kasperbauer, Tyler Joshua

    2015-01-01

    Debates over egalitarianism for the most part are not concerned with constraints on achieving an egalitarian society, beyond discussions of the deficiencies of egalitarian theory itself. This paper looks beyond objections to egalitarianism as such and investigates the relevant psychological...... processes motivating people to resist various aspects of egalitarianism. I argue for two theses, one normative and one descriptive. The normative thesis holds that egalitarians must take psychological constraints into account when constructing egalitarian ideals. I draw from non-ideal theories in political...... philosophy, which aim to construct moral goals with current social and political constraints in mind, to argue that human psychology must be part of a non-ideal theory of egalitarianism. The descriptive thesis holds that the most fundamental psychological challenge to egalitarian ideals comes from what are...

    Stabilization policy under centralized wage-setting is represnted as a non-cooperative game between an encompassing union and the government. The dilemma of the government is whether or not to accommodate supply disturbances when it cannot tell if they are due an intentionally militant wage policy or to unforeseen external price shocks. In a single round of wage setting, there is no government strategy which can both guarantee full employment and prevent union militancy. In a repeated game, h...

  16. Holocene reef development where wave energy reduces accommodation

    Grossman, Eric E.; Fletcher, Charles H.

    2004-01-01

    Analyses of 32 drill cores obtained from the windward reef of Kailua Bay, Oahu, Hawaii, indicate that high wave energy significantly reduced accommodation space for reef development in the Holocene and produced variable architecture because of the combined influence of sea-level history and wave exposure over a complex antecedent topography. A paleostream valley within the late Pleistocene insular limestone shelf provided accommodation space for more than 11 m of vertical accretion since sea level flooded the bay 8000 yr BP. Virtually no net accretion (pile-up of fore-reef-derived rubble (rudstone) and sparse bindstone, and (3) a final stage of catch-up bindstone accretion in depths > 6 m. Coral framestone accreted at rates of 2.5-6.0 mm/yr in water depths > 11 m during the early Holocene; it abruptly terminated at ~4500 yr BP because of wave scour as sea level stabilized. More than 4 m of rudstone derived from the upper fore reef accreted at depths of 6 to 13 m below sea level between 4000 and 1500 yr BP coincident with late Holocene relative sea-level fall. Variations in the thickness, composition, and age of these reef facies across spatial scales of 10-1000 m within Kailua Bay illustrate the importance of antecedent topography and wave-related stress in reducing accommodation space for reef development set by sea level. Although accommodation space of 6 to 17 m has existed through most of the Holocene, the Kailua reef has been unable to catch up to sea level because of persistent high wave stress.

  17. The level of burnout of housekeeping personnel in accommodation facilities

    Sibel Erkal

    2012-08-01

    Full Text Available This study aimed to determine the level of burnout of the housekeeping personnel (cleaner, manager, crew chief working in accommodation facilities and discovering if there was a relationship between their level of burnout and their personal features. In the study a cluster sampling method was used. 12 accommodation facilities in Antalya were handled as cluster and a total of 146 personnel working in these facilities comprised the sample group. A “Burnout Inventory” was used in the study. The study data were analyzed in the SPSS 14.01 program and t-test was used in the data analysis, while the Tukey test was used in the variance analysis and paired comparison. Significant relationships were detected between the level of burnout of the housekeeping personnel participating in the study and their level of education, income level, duties, working time in the facility, weekly working hours, daily working hours, level of satisfaction related to their jobs and their wish to change their jobs (p<0.05. A person experiencing burnout is exhausted and disappointed since he does not gain the things he expected from his way of life or relationships. That’s why it is necessary to approach a burnout event in a multi-dimensional way and deal with the factors causing burnout in different ways. In the literature review there was no study examining the level of burnout concerning individual housekeeping personnel working in accommodation facilities. this study was planned and carried out with this aim.

  18. Optical analysis on induction of focal accommodation using cylindrical lenses

    Mano, Yuichiro; Kakeya, Hideki

    2008-02-01

    In the present paper the authors analyze detailed optics of stereoscopic display combining cylindrical lenses and embedded striped patterns, which has been proposed to reduce the contradiction between binocular parallax and focal accommodation of the eyes. The proposed system lets the viewer see an image including high frequency striped patterns through a cylindrical lens. When the viewer is shown a striped pattern through a cylindrical lens, the depth on which his/her eyes focus depends on the inclination angle of stripes, for the cylindrical lens works as a lens with different focal length depending on the orientation of lines. To control the status of accommodation correctly, it is necessary to obtain the correspondence between the inclination angle of stripes and the focusing distance. To attain this goal we make a computer simulator to calculate the 3D optical paths. The validity of the computer simulator is confirmed by physical experiments with a cylindrical lens and a camera finder to measure the focal convergence of striped lines. We also confirm that this system can induce desired focal accommodation by measuring the eyes of the viewer seeing striped patterns through a cylindrical lens.

  19. ABOUT GENERAL INFRASTRUCTURE AND ACCOMMODATION SYSTEM IN ROMANIAN BALNEOLOGY

    ILIE ROTARIU

    2013-12-01

    Full Text Available A strong infrastructure is a precondition for the development of balneology. On this base new tourism might build the modern services that supply the experiences. The key factor is the labor force: an EU project about labor force in Romania and Bulgaria in balneology allow us to present the preliminary findings focusing on general infrastructure and accommodation which allow the development of the balneology as well as the additional conditions as the existence of a social pact, easy access facilities etc. Our paper gives more details about the accommodation facilities in Romania insisting about the results of the transition and privatization of the former socialist facilities and the transformation of the property into private ones and the consequences of this. It also present the capability of new developed accommodation units built after 1990 and how they might compete in an international competition. The findings force us to conclude that the actual facilities do not allow the balneology resorts to compete in the international competition and might fill only a poor and low demanding tourists

  20. Constraint-based scheduling applying constraint programming to scheduling problems

    Baptiste, Philippe; Nuijten, Wim

    2001-01-01

    Constraint Programming is a problem-solving paradigm that establishes a clear distinction between two pivotal aspects of a problem: (1) a precise definition of the constraints that define the problem to be solved and (2) the algorithms and heuristics enabling the selection of decisions to solve the problem. It is because of these capabilities that Constraint Programming is increasingly being employed as a problem-solving tool to solve scheduling problems. Hence the development of Constraint-Based Scheduling as a field of study. The aim of this book is to provide an overview of the most widely used Constraint-Based Scheduling techniques. Following the principles of Constraint Programming, the book consists of three distinct parts: The first chapter introduces the basic principles of Constraint Programming and provides a model of the constraints that are the most often encountered in scheduling problems. Chapters 2, 3, 4, and 5 are focused on the propagation of resource constraints, which usually are responsibl...

  1. An efficient method for minimizing a convex separable logarithmic function subject to a convex inequality constraint or linear equality constraint

    2006-01-01

    Full Text Available We consider the problem of minimizing a convex separable logarithmic function over a region defined by a convex inequality constraint or linear equality constraint, and two-sided bounds on the variables (box constraints. Such problems are interesting from both theoretical and practical point of view because they arise in some mathematical programming problems as well as in various practical problems such as problems of production planning and scheduling, allocation of resources, decision making, facility location problems, and so forth. Polynomial algorithms are proposed for solving problems of this form and their convergence is proved. Some examples and results of numerical experiments are also presented.

  4. Evaluating E-learning Programs: An Adaptation of Kirkpatrick's Model to Accommodate E-learning Environments

    Full Text Available Problem Statement: Kirkpatrick's model for the evaluation of training programs has been a staple in institutional learning since 1959 and is easily applicable to any training program. Approach: This model, however, was developed for traditional learning environments and has been regarded as antiquated, especially when one took into consideration the fact that institutional learning has increasingly taken on the form of e-learning. This study proposed an adaptation of Kirkpatrick's model, which accommodated the nuances of the e-learning environment. This model proposed a tri-stage mode of evaluation. Results: The three stages were interaction, learning and results. The interaction stage took into consideration the special challenges posed by the environment while the learning and results stages examined the alignment between the curriculum and the needs of an organization. Conclusions/Recommendations: The research conducted supported the thesis that existing training models fail to accommodate for e-learning environments and, in establishing important guidelines and criteria for the remediation as such, addressed the initial concern. The proposed evaluation method is one that is rudimentary in nature and holds a great promise for practical application.

  5. Framing effectiveness in impact assessment: Discourse accommodation in controversial infrastructure development

    There is ongoing debate about the effectiveness of impact assessment tools, which matters both because of the threat to future practice of the tools which are frequently perceived to be ineffective, and because of the disillusionment that can ensue, and controversy generated, amongst stakeholders in a decision context where opportunities for meaningful debate have not been provided. In this article we regard debate about the meaning of effectiveness in impact assessment as an inevitable consequence of increased participation in environmental decision-making, and therefore frame effectiveness based on an inclusive democracy role to mean the extent to which impact assessment can accommodate civil society discourse. Our aim is to investigate effectiveness based on this framing by looking at one type of impact assessment – environmental impact assessment (EIA) – in two controversial project proposals: the HS2 rail network in England; and the A4DS motorway in the Netherlands. Documentary analysis and interviews held with key civil society stakeholders have been deployed to identify discourses that were mobilised in the cases. EIA was found to be able to accommodate only one out of four discourses that were identified; for the other three it did not provide the space for the arguments that characterised opposition. The conclusion in relation to debate on framings of effectiveness is that EIA will not be considered effective by the majority of stakeholders. EIA was established to support decision-making through a better understanding of impacts, so its ineffectiveness is unsurprising when its role is perceived to be broader. However, there remains a need to map discourses in different decision contexts and to analyse the extent to which the range of discourses are accommodated throughout the decision process, and the role of impact assessment in those processes, before recommendations can be made to either improve impact assessment effectiveness, or whether it is

    on transformation operators that apply to integrity constraints written in a rich DATALOG-like language with negation. The resulting procedure produces, at design-time, simplified constraints for parametric transaction patterns, which can then be instantiated and checked for consistency at run-time. These tests......Without proper simplification techniques, database integrity checking can be prohibitively time consuming. Several methods have been developed for producing simplified incremental checks for each update but none until now of sufficient quality and generality for providing a true practical impact...... is strictly related to query containment; in fact, an ideal simplification procedure can only exist in database languages for which query containment is decidable. However, simplifications that do not qualify as ideal may also be relevant for practical purposes. We present a concrete approach based...

  8. A simple proposal for a physiological-optical solution to the accommodation-vergence mismatch problem of the 3D displays

    Kim, Dal-Young

    2011-01-01

    Here is suggested a solution to the accommodation-vergence mismatch problem in the 3D stereoscopic display. It can be achieved by compensating the mismatched focal length with adjustable-focus 3D glasses. The compensation would make the vergence of human eyes match with the virtual stereo-image and reduce the visual fatigue. Some additive considerations for practical operation are discussed.

  9. Accommodation Decision Making for Postsecondary Students With Learning Disabilities: Individually Tailored or One Size Fits All?

    Clinicians uniformly recommend accommodations for college students with learning disabilities; however, we know very little about which accommodations they select and the validity of their recommendations. We examined the assessment documentation of a large sample of community college students receiving academic accommodations for learning disabilities to determine (a) which accommodations their clinicians recommended and (b) whether clinicians' recommendations were supported by objective data gathered during the assessment process. In addition to test and instructional accommodations, many clinicians recommended that students with learning disabilities should have different educational expectations, standards, and methods of evaluation (i.e., grading) than their nondisabled classmates. Many of their recommendations for accommodations were not supported by objective evidence from students' history, diagnosis, test data, and current functioning. Furthermore, clinicians often recommended accommodations that were not specific to the student's diagnosis or area of disability. Our findings highlight the need for individually selected accommodations matched to students' needs and academic contexts. PMID:25395372

  10. Big brake singularity is accommodated as an exotic quintessence field

    Chimento, Luis P.; Richarte, Martín G.

    2015-01-01

    We describe a big brake singularity in terms of a modified Chaplygin gas equation of state $p=(\\ga_{m}-1)\\rho+\\al\\ga_{m}\\rho^{-n}$, accommodate this late-time event as an exotic quintessence model obtained from an energy-momentum tensor, and focus on the cosmological behavior of the exotic field, its kinetic energy and the potential energy. At the background level, the exotic field does not blow up whereas its kinetic energy and potential both grow without limit near the future singularity. W...
