    2015-01-01

    As interactive systems are quickly becoming integral to our everyday lives, this book investigates how we can make these systems, from desktop and mobile apps to more wearable and immersive applications, more usable and maintainable by using HCI design patterns. It also examines how we can facilitate the reuse of design practices in the development lifecycle of multi-devices, multi-platforms and multi-contexts user interfaces. Effective design tools are provided for combining HCI design patterns and User Interface (UI) driven engineering to enhance design whilst differentiating between UI

  2. Teaching HCI Design With the Studio Approach

    Jacobs Reimer, Yolanda; Douglas, Sarah A.

    2003-09-01

    The studio-based method of teaching has been used for almost 100 years to teach product and architecture design. With ever increasing pressure on HCI to teach competence in designing interactive objects, new ways of teaching need to be explored. This article begins with a review of the studio-based teaching concept and how it has been used in architecture, science/engineering, and computer science education. We then present and discuss the evaluation of an HCI design studio course which we created and taught in spring 2002 in the Computer and Information Science Department of the University of Oregon. This course was based on our observations and study of studio courses in the School of Architecture. Finally, we review general issues about studio teaching including the promises and challenges that it presents to widespread acceptance in the computer science curriculum.

    This paper reports a study of the use of activity theory in human–computer interaction (HCI) research. We analyse activity theory in HCI since its first appearance about 25 years ago. Through an analysis and meta-synthesis of 109 selected HCI activity theory papers, we created a taxonomy of 5...... different ways of using activity theory: (1) analysing unique features, principles, and problematic aspects of the theory; (2) identifying domain-specific requirements for new theoretical tools; (3) developing new conceptual accounts of issues in the field of HCI; (4) guiding and supporting empirical...... analyses of HCI phenomena; and (5) providing new design illustrations, claims, and guidelines. We conclude that HCI researchers are not only users of imported theory, but also theory-makers who adapt and develop theory for different purposes....

    2012-01-01

    Human-centered informatics (HCI) is a young discipline that is still defining its core components, with approaches rooted in engineering, science, and creative design. In the spirit of this book series, this book explores HCI as an intersection point for different perspectives of computing and information technology, seeking to understand how groups of designers can communicate with an increasingly diverse set of colleagues on a broadening set of problems. In so doing, this book traces the evolution of claims as a way to capture and share knowledge, particularly in comparison to other approach

    2015-06-01

    Full Text Available Courses on Human Computer Interaction (HCI largely differ in the conception of the role of the course in the program, in the topics to be included, in emphases, in the instructional strategies that are employed, and more. This paper describes the design and implementation of a HCI course for students of the Management Information Systems department in our college. Students’ intermediate and final homework assignments were analyzed to provide feedback for the course design. Quantitative analysis showed high correlation between the quality of the requirement analysis performed by the students and the quality of the final interface prototype, and also that the quality of design alternatives that were considered by the students can be a good predictor for the quality of the overall interface design. Qualitative analysis of students’ submissions showed the need for practicing skills required in users’ studies, especially conducting interviews and observations. Implications from these and other findings are discussed.

    2006-01-01

    In order to solve the low efficiency and poor precision problems of traditional ink control methods on domestic offset printers, developing modern ink automatic control system has become more and more urgent. As an important subsystem, the human computer interface (HCI) is a key function for the wholly automatic control. Once this goal is obtained, all the printing procedures especially the automatic control of ink volume should be finished with human computer interface in different areas. Considering the HCI design theory and structure characteristics of domestic printers comprehensively, the HCI prototype for automatic ink control system has been developed based on Visual Basic platform. As the individual ink key is instead of the integrated key, the division result of ink fountain can be displayed on the interface. Through the interface, the dynamic adjusting functions such as modifying ink volume, locking or unlocking each ink key and real-time displaying the adjusting results etc. can be completed. The simulation test has shown that the opening and practical feature of the prototype is satisfactory.

  1. A fresh recipe for designers: HCI approach to explore the nexus between design techniques and formal methods in software development

    Directory of Open Access Journals (Sweden)

    Julian Galindo Losada

    2016-11-01

    Full Text Available Emerging companies involved in design and implementation of innovative products demand multidisciplinary teams to be competitive in the market. This need mainly exposes designers to extend their knowledge not only in User Interface elements of the design process but also in software methodologies to cover the lack of resources and expertise in start-ups. It raises the question of how designers can line up HCI techniques with best practices in software development while preserving usability and easy-to-use principles. To explore this gap, this paper proposes an approach which combines existing technology and methods by studying the nexus between HCI prototyping and software engineering. The approach is applied into a case study in the design of a virtual shop harmonizing the use of storyboards and the spiral. A comprehensive analysis is performed by using a Technology acceptance model (TAM regarding with two variables: usability and easy-to-use. The present finding underlines the positive integration of HCI techniques and formal methods without compromising user satisfaction with a potential benefit for small companies in a formation stage.

    2016-08-01

    Full Text Available This paper presents the results of two studies involving “flipping the classroom”. Teaching material was delivered via interactive “e-lectures”, allowing face-to-face sessions to focus instead on practice. The e-lectures were designed according to standard usability principles coupled with recent research into the effect of interactivity on learning. The effectiveness of the use of e-lectures was then evaluated using an online survey. The results suggest that students prefer the flexibility offered by e-lectures compared to conventional lectures. The results contribute to our understanding of how this technology fits with face-to-face teaching in the digital age.

  4. Cognition In Hci: An Ongoing Story

    Directory of Open Access Journals (Sweden)

    Jörn Hurtienne

    2009-01-01

    Full Text Available The field of human computer interaction (HCI is deeply rooted in cognitive science. But can cognitive science still contribute to the newest developments? This article introduces the recent trends towards “embodied cognition.” Then research on image schemas and their metaphorical extensions is reviewed as an example of how understanding a special branch of embodied cognition can be useful to HCI. Special emphasis is placed on the validity of the theory and its practicability in different phases of the user interface design cycle. It is concluded that cognition can still contribute to current HCI and that the dialogue between the different schools of thought is beneficial to the field.

    Differences in cultural contexts constitute differences in cognition, and research has shown that different cultures may use different cognitive tools for perception and reasoning. The cultural embeddings are significant in relation to HCI, because the cultural context is also embedded...... in the techniques and the tools that we apply. We lack a framework for discussing what and who we are, when we talk about a person as the user of an ICT system that has to be designed, developed and implemented. As a framework, we suggest a theory of complementary positions that insists on solid accounts from all...... observer posi-tions in relation to perspective, standpoint and focus. We need to develop com-plementary theories that embed complexity, and we need to reflect critically upon forty years of dominance by rationalistic, empirical understandings of the user as illustrated in the literature and practice within...

    The question "What to Study in HCI" has two parts. First it asks how HCI researchers think about the research challenges they tackle: how do they decide what problems to engage with and how to study them? Second, the question also asks what is the subject of HCI: which challenges should researchers...... from addressing these questions so as to develop their practical understanding (e.g., "tricks of the trade") of how to tackle the complexity of selecting "what to study". Second, we argue that researchers can benefit from thinking about the epistemological grounds upon which they base their everyday...... work, that is, thinking about what HCI is.

We adapt the sociotechnical HCI approach called human work......Ensuring ethical value exchange is moving to the forefront of the global challenges that HCI will have to address in the coming years In this position paper, we argue that applying a context-sensitive, sociotechnical approach to HCI can help meet the challenge. The background is that the life...... of marginalized people in contemporary society is challenging and uncertain. The marginalized can face health and cognitive issues as well as a lack of stability of social structures such as family, work and social inclusion. Three questions are of concern when innovating together with people ‘at the margins...

  12. Physical Activity Design Guidelines for School Architecture.

    Directory of Open Access Journals (Sweden)

    Jeri Brittin

    Full Text Available Increasing children's physical activity at school is a national focus in the U.S. to address childhood obesity. While research has demonstrated associations between aspects of school environments and students' physical activity, the literature currently lacks a synthesis of evidence to serve as a practical, spatially-organized resource for school designers and decision-makers, as well as to point to pertinent research opportunities. This paper describes the development of a new practical tool: Physical Activity Design Guidelines for School Architecture. Its aims are to provide architects and designers, as well as school planners, educators, and public health professionals, with strategies for making K-12 school environments conducive to healthy physical activity, and to engage scientists in transdisciplinary perspectives toward improved knowledge of the school environment's impact. We used a qualitative review process to develop evidence-based and theory-driven school design guidelines that promote increased physical activity among students. The design guidelines include specific strategies in 10 school design domains. Implementation of the guidelines is expected to enable students to adopt healthier physical activity behaviors. The tool bridges a translational gap between research and environmental design practice, and may contribute to setting new industry and education standards.

    The objective of this study is to develop human factors engineering program review guidelines and alarm system review guidelines in order to resolve the two major technical issues: 25. Human Factors Engineering Program Review Model and 26. Review Criteria for Human Factors Aspects of Advanced Controls and Instrumentation, which are related to the development of human factors safety regulation guides being performed by KINS. For the development of human factors program review guidelines, we made a Korean version of NUREG-0711 and added our comments by considering Korean regulatory situation and reviewing the reference documents of NUREG-0711. We also computerized the Korean version of NUREG-0711, additional comments, and selected portion of the reference documents for the developer of safety regulation guides in KINS to see the contents comparatively at a glance and use them easily. For the development of alarm system review guidelines, we made a Korean version of NUREG/CR-6105, which was published by NRC in 1994 as a guideline document for the human factors review of alarm systems. Then we will update the guidelines by reviewing the literature related to alarm design published after 1994. (author). 12 refs., 5 figs., 2 tabs.

    Semiotic engineering was originally proposed as a semiotic approach to designing user interface languages. Over the years, with research done at the Department of Informatics of the Pontifical Catholic University of Rio de Janeiro, it evolved into a semiotic theory of human-computer interaction (HCI). It views HCI as computer-mediated communication between designers and users at interaction time. The system speaks for its designers in various types of conversations specified at design time. These conversations communicate the designers' understanding of who the users are, what they know the us

    Full Text Available This paper presents design guidelines and recommendations for developing cursor manipulation interaction devices to be employed in a wearable context. The work presented in this paper is the culmination three usability studies designed to understand commercially available pointing (cursor manipulation devices suitable for use in a wearable context. The set of guidelines and recommendations presented are grounded on experimental and qualitative evidence derived from three usability studies and are intended to be used in order to inform the design of future wearable input devices. In addition to guiding the design process, the guidelines and recommendations may also be used to inform users of wearable computing devices by guiding towards the selection of a suitable wearable input device. The synthesis of results derived from a series of usability studies provide insights pertaining to the choice and usability of the devices in a wearable context. That is, the guidelines form a checklist that may be utilized as a point of comparison when choosing between the different input devices available for wearable interaction.

    We developed a new tool, Healthy Eating Design Guidelines for School Architecture, to provide practitioners in architecture and public health with a practical set of spatially organized and theory-based strategies for making school environments more conducive to learning about and practicing healthy eating by optimizing physical resources and learning spaces. The design guidelines, developed through multidisciplinary collaboration, cover 10 domains of the school food environment (eg, cafeteria, kitchen, garden) and 5 core healthy eating design principles. A school redesign project in Dillwyn, Virginia, used the tool to improve the schools' ability to adopt a healthy nutrition curriculum and promote healthy eating. The new tool, now in a pilot version, is expected to evolve as its components are tested and evaluated through public health and design research.

    In the field of Human Computer Interaction (HCI), we use a variety of Knowledge Elicitation (KE) techniques to capture user cognitive issues e.g. via interviews, paper prototyping, card sorting, focus group debates and more. MIKE (Mobile Interactive Knowledge Elicitation) is an ongoing research direction to enhance the KE capabilities of HCI practitioners via mobile and electronic methods. MIKE tools are a suite of Mobile HCI software and hardware configurations for a variety of mobile platforms. With MIKE's CONKER we describe a Collaborative Non-linear Knowledge Elicitation Repository for HCI practitioners. Its intention is to provide a scalable infrastructure for supporting the management and collaborative retrieval of mobile based KE datasets. Some of its functional design requirements include HCI practitioner profiles management, managing experimental progress from dispersed mobile HCI teams, timetabling expenditures for time critical empirical capture and participant management, and enabling concurrent HCI specialists to compare elicited mobile data. Further expansion of the CONKER system will include incorporation of distributed psychometric analysis methods. CONKER is realized as a sourceforge-alike Web-Portal using state-of-the-art web-framework technologies. We describe several approaches to the capturing and management of HCI data and how CONKER makes this available to the HCI community.

    Rau, P L; Salvendy, G

    2001-03-15

    The aim was to design a human-centred electronic mail (e-mail) address system based on networking technology and cognitive ergonomics. Based on the background literature and the results of users' survey, a conceptual model is developed for designing e-mail addresses. This model consists of e-mail address components of formats, domain length, meaningfulness, orientation and information type pertaining to recall, information association and categorization. Five hypotheses were proposed to test the conceptual model, and four experiments were conducted with 85 participants to test the hypotheses. The dependent variables were performance time, error rate and degree of satisfaction, and the independent variables were components of the e-mail addresses. The main results indicate that for a recall task, significantly lower total performance time (26.2%) and error rate (75%) were found for the hybrid formats (digits and letters) than for the letter format, and up to four characters was the best single domain length. For an information association task, embedding both geographical and organizational information significantly decreased the response time (10.9%) in comparison with only embedding organizational information. For a categorization task, embedding both geographical information and organizational information significantly decreased response time (40.7%) in comparison with only embedding organizational information. This research demonstrates the importance of human-centred design and provides guidelines in effectively designing e-mail addresses.

    There are two main objectives to this publication. The first is to find out the communalities in the experience gained in previous studies and in actual applications of solar technologies in buildings, residential as well as nonresidential. The second objective is to review innovative concepts and products which may have an impact on future developments and applications of solar technologies in buildings. The available information and common lessons were collated and presented in a form which, hopefully, is useful for architects and solar engineers, as well as for teachers of "solar architecture" and students in Architectural Schools. The publication is based mainly on the collection and analysis of relevant information. The information included previous studies in which the performance of solar buildings was evaluated, as well as the personal experience of the Author and the research consultants. The state of the art, as indicated by these studies and personal experience, was summarized and has served as basis for the development of the Design Guidelines. In addition to the summary of the state of the art, as was already applied in solar buildings, an account was given of innovative concepts and products. Such innovations have occurred in the areas of thermal storage by Phase Change Materials (PCM) and in glazing with specialized or changeable properties. Interesting concepts were also developed for light transfer, which may enable to transfer sunlight to the core areas of large multi story nonresidential buildings. These innovations may have a significant impact on future developments of solar technologies and their applications in buildings.

    2006-02-01

    Knowledge Elicitation (KE) methods are an integral part of Human Computer Interaction (HCI) practices. They are a key aspect to the synthesis of psychology empirical methods with requirements engineering, User Centred Design (UCD) and user evaluations. Examples of these methods include prototyping, focus groups, interviews, surveys and direct video observation. The MIKE project (Mobile Interactive Knowledge Elicitation) at the Centre for HCI Design, City University London, UK provides mobile cyberscience capabilities for HCI practitioners conducting such research while at stakeholder locations. This paper reports on the design and development of a new MIKE based tool, named PET, a Participant-based Experiment Tracking tool for HCI practitioners using Java-based (J2ME) mobile devices. PET integrates its user tracking techniques with the development of the second generation implementation of the CONKER (COllaborative Non-linear Knowledge Elicitation Repository) Web Service. We thus report further on CONKER v2.0's new capabilities developed to enable tighter collaboration and empirical data management between HCI practitioners, considering their UCD needs. The visualisation, tracking and recording of HCI participant-based datasets via PET is explored with close connectivity with the CONKER v2.0 Web Service, in order to provide mobile-web cyberscience for remote and local HCI practitioners.

    An improved hot carrier injection (HCI) degradation model was proposed based on interface trap gen-eration and oxide charge injection theory. It was evident that the degradation behavior of electric parameters such as I_(dlin), I_(dsat), G_m and V_t fitted well with this model. Devices were prepared with 0.35μm technology and different LDD processes, I_(dlin) and I_(dsat) after HCI stress were analyzed with the improved model. The effects of interface trap generation and oxide charge injection on device degradation were extracted, and the charge injection site could be obtained by this method. The work provides important information to device designers and process engineers.

    2016-01-01

    Development of refrigerators based on Thermoacoustic technology is a novel solution to the present day need of cooling without causing environmental hazards. With added advantages of absence of moving parts and circulating refrigerants, these devices can attain very low temperatures maintaining a compact size. The present theoretical work is based on theory of linear thermoacoustics[1]. Under the short stack and invicid assumptions, an algorithm for design of a standing wave thermoacoustic refrigerator, with main focus on the stack, is described. A stack is designed for a given cooling requirement of the refrigerator and certain chosen operation parameters.

  15. HCI challenges in Dance Education

    2016-08-01

    Full Text Available Dance learning is by nature multimodal, while dance practice presents a wide diversity across genres and contexts. Choreography and artistic contemporary dance performances have been using interactive technologies to support their creative process for several decades. Nevertheless the use of interactive technologies to support dance learning and education is still relatively immature and raises many challenges and interesting questions when it comes to choosing the appropriate human computer interaction methods. In this paper, we present the characteristics of dance teaching and learning in relation to interactive technology and we highlight the points/feedback that dance, as a field of mastering expressive movement, can bring to the design of whole-body interaction experiences.

    Science.gov (United States)

    Strubbe, Linda

    2015-03-01

    We astronomy outreachers are passionate about sharing astronomy widely-but many astronomy outreach activities are designed more by how we hope things will work than in a careful intentional way. We also rarely evaluate how well our activities are achieving our goals. As a result, many educational activities must be significantly less effective than they could be. Fortunately, there is a large body of education research on how people learn. If we are serious about sharing astronomy widely and effectively, we must treat our teaching like research: (1) Have clear goals for our outreach, evaluate how well we are achieving our goals, and revise our strategies in light of what we learn; and (2) Use appropriate teaching techniques supported by education research wherever possible.

    2015-01-01

    User frustration research has been one way of looking into clinicians' experience with health information technology use and interaction. In order to understand how clinician frustration with Health Information Technology (HIT) use occurs, there is the need to explore Human-Computer Interaction (HCI) literature that addresses both frustration and HIT use. In the past three decades, HCI frustration research has increased and expanded. Researchers have done a lot of work to understand emotions, end-user frustration and affect. This paper uses a historical literature review approach to review the origins of emotion and frustration research and explore the research question; Does HCI research on frustration provide insights on clinicians' frustration with HIT interfaces? From the literature review HCI research on emotion and frustration provides additional insights that can indeed help explain user frustration in HIT. Different approaches and HCI perspectives also help frame HIT user frustration research as well as inform HIT system design. The paper concludes with a suggested directions on how future design and research may take.

  12. Advanced human-system interface design review guideline. General evaluation model, technical development, and guideline description

    Energy Technology Data Exchange (ETDEWEB)

    O`Hara, J.M.

    1994-07-01

    Advanced control rooms will use advanced human-system interface (HSI) technologies that may have significant implications for plant safety in that they will affect the operator`s overall role in the system, the method of information presentation, and the ways in which operators interact with the system. The U.S. Nuclear Regulatory Commission (NRC) reviews the HSI aspects of control rooms to ensure that they are designed to good human factors engineering principles and that operator performance and reliability are appropriately supported to protect public health and safety. The principal guidance available to the NRC, however, was developed more than ten years ago, well before these technological changes. Accordingly, the human factors guidance needs to be updated to serve as the basis for NRC review of these advanced designs. The purpose of this project was to develop a general approach to advanced HSI review and the human factors guidelines to support NRC safety reviews of advanced systems. This two-volume report provides the results of the project. Volume I describes the development of the Advanced HSI Design Review Guideline (DRG) including (1) its theoretical and technical foundation, (2) a general model for the review of advanced HSIs, (3) guideline development in both hard-copy and computer-based versions, and (4) the tests and evaluations performed to develop and validate the DRG. Volume I also includes a discussion of the gaps in available guidance and a methodology for addressing them. Volume 2 provides the guidelines to be used for advanced HSI review and the procedures for their use.

    Activity theory -- a conceptual framework originally developed by Aleksei Leontiev -- has its roots in the socio-cultural tradition in Russian psychology. The foundational concept of the theory is human activity, which is understood as purposeful, mediated, and transformative interaction between human beings and the world. Since the early 1990s, activity theory has been a visible landmark in the theoretical landscape of Human-Computer Interaction (HCI). Along with some other frameworks, such as distributed cognition and phenomenology, it established itself as a leading post-cognitivist approac

    Bosia, Daniela; Marino, Donatella; Peretti, Gabriella

    2016-01-01

    Healthcare building humanisation is currently a widely debated issue and the development of patient centered and evidence based design is growing worldwide. Many international health organizations and researchers understand the importance of Patient Centred Design and leading architects incorporate it into the design process. In Italy this design approach is still at an early stage. The article refers to research commissioned by the Italian Health Ministry and carried out by R. Del Nord (Università degli Studi di Firenze) and G. Peretti (Politecnico di Torino) with their collaborators. The scope of the research was the definition of design guidelines for healthcare facilities humanisation. The methodology framework adopted is the well established need and performance approach in architectural design. The article deals with the results of statistical investigations for the definition and ranking of users' needs and the consistent expression of their requirements. The investigations were carried out with the cooperation of psychologists of the Università degli Studi di Torino and researchers of the Università degli Studi di Cagliari. The proposed evaluation system allows ranking of health facilities according to the level of humanisation achieved. The statistical investigation evidence collected allowed the definition of humanisation design guidelines for health-care facilities and for the assessment of their specific level of humanisation.

    An improved hot carrier injection (HCI) degradation model was proposed based on interface trap generation and oxide charge injection theory. It was evident that the degradation behavior of electric parameters such as Idlin, Idsat, Gm and Vt fitted well with this model. Devices were prepared with 0.35 μm technology and different LDD processes. Idlin and Idsat after HCI stress were analyzed with the improved model. The effects of interface trap generation and oxide charge injection on device degradation were extracted, and the charge injection site could be obtained by this method. The work provides important information to device designers and process engineers.

    This paper presents the design and investigation of 16-QAM optical modulator based on plasmonic-polymer hybrid slot waveguides. The design is CMOS-compatible and uses dual-parallel Mach-Zehnder modulator (DPMZM) followed by a phase modulator (PM). Careful consideration is given to design low loss photonic-plasmonic interfaces to ensure efficient coupling between silicon and plasmonic waveguide. The effect of slot widths on device performance is investigated comprehensively using COMSOL software simulation along with analytical analysis for both gold and silver contact. The results can be used as a guideline to design compact and high speed all-plasmonic 16-QAM modulators for 1550 nm wavelength communication systems.

    Energy Technology Data Exchange (ETDEWEB)

    Carter, R.J.

    1997-07-01

    This report documents the work conducted in four tasks of the Nuclear Regulatory Commission (NRC) project entitled Review Criteria for Human Factors Aspects of Advanced Controls and Instrumentation. The purpose of the first task was to integrate the applicable sections of NUREG-0700 into the advanced control room design review (ACRDR) guidelines to ensure that all applicable guidelines are together in one document and conveniently accessible to users. The primary objective of the second task was to formulate a strategy for the development of new ACRDR guidelines that have not otherwise been identified. The main focus of the third task was to modify the individual ACRDR guidelines generated to date to ensure that they are suitable for the intended nuclear power plant (NPP) control station system application. The goal of the fourth task was to develop human factors guidelines for two human-system interface categories that are missing from the current ACRDR guidelines document. During the first task those areas in NUREG-0700 that are not addressed by the ACRDR guidelines document were identified, the areas were subsequently reviewed against six recent industry human factors engineering review guidelines, and the NUREG-0700 guidelines were updated as necessary. In the second task 13 general categories of human-system interface guidelines that are either missing from or not adequately addressed by the ACRDR document were discovered. An approach was derived for the development of new ACRDR guidelines, a preliminary assessment of the available sources that may be useful in the creation of new guidelines and their applicability to the identified human-system interface categories was performed, and an estimate was made of the amount of time and level of effort required to complete the development of needed new ACRDR guidelines. During the third task those NPP control station systems to which the NUREG-0700 and ACRDR guidelines apply were identified, matrices of such

    Sound, vibration, noise and privacy have significant impacts on health and performance. As a result, they are recognized as essential components of effective health care environments. However, acoustics has only recently become a prominent consideration in the design, construction, and operation of healthcare facilities owing to the absence, prior to 2010, of clear and objective guidance based on research and best practices. Sound & Vibration 2.0 is the first publication to comprehensively address this need. Sound & Vibration 2.0 is the sole reference standard for acoustics in health care facilities and is recognized by: the 2010 FGI Guidelines for the Design and Construction of Health Care Facilities (used in 60 countries); the US Green Building Council’s LEED for Health Care (used in 87 countries); The Green Guide for Health Care V2.2; and the International Code Council (2011).

    The interim guidelines for the application of inelastic analysis to design of fast reactor components were developed. These guidelines are referred from 'Elevated Temperature Structural Design Guide for Commercialized Fast Reactor (FDS)'. The basic policies of the guidelines are more rational predictions compared with elastic analysis approach and a guarantee of conservative results for design conditions. The guidelines recommend two kinds of constitutive equations to estimate strains conservatively. They also provide the methods for modeling load histories and estimating fatigue and creep damage based on the results of inelastic analysis. The guidelines were applied to typical design examples and their results were summarized as exemplars to support users.

    Full Text Available This article sets forth the early phases of a methodological proposal for designing and developing Volunteered Geographic Information (VGI initiatives based on a system perspective analysis in which the components depend and interact dynamically among each other. First, it focuses on those characteristics of VGI projects that present different goals and modes of organization, while using a crowdsourcing strategy to manage participants and contributions. Next, a tool is developed in order to design the central crowdsourced processing unit that is best suited for a specific project definition, associating it with a trend towards crowd-based or community-driven approaches. The design is structured around the characterization of different ways of participating, and the task cognitive demand of working on geo-information management, spatial problem solving and ideation, or knowledge acquisition. Then, the crowdsourcing process design helps to identify what kind of participants are needed and outline subsequent engagement strategies. This is based on an analysis of differences among volunteers’ participatory behaviors and the associated set of factors motivating them to contribute, whether on a crowd or community-sourced basis. From a VGI system perspective, this paper presents a set of guidelines and methodological steps in order to align project goals, processes and volunteers and thus successfully attract participation. This methodology helps establish the initial requirements for a VGI system, and, in its current state, it mainly focuses on two components of the system: project and participants.

  7. Equipment design guidelines for remote hot cell operations.

    Wahlquist, D. R.

    1998-07-10

    Hot cells provide a unique and challenging environment for designing remotely operated equipment. A typical hot cell is an isolated room used to protect operators from highly contaminated and radioactive equipment. Hot cells usually have thick reinforced concrete walk and leaded glass windows. Operations within the hot cell are accomplished using master-slave manipulators and overhead crane or electro-mechanical manipulator systems. The inability to perform hands-on operation and maintenance in hot cells requires special design considerations. Some of these design considerations include operational interfaces, radiation, accessibility, replaceability/interchangeability, decontamination, atmospheric conditions, functionality, operator fatigue, and ease of use. This paper will discuss guidelines for designing hot cell remotely operated equipment that has been used successfully at Argonne National Laboratory. General topics in this paper will include master-slave manipulator types and limitations, overhead handling systems, viewing limitations, types and sizes of typical fasteners, hot cell compatible materials, mockup testing, guide features for mating parts, modularity, labeling, electrical fasteners, and lifting fixtures.

    Ocean waves are one of the cleanest and most abundant energy sources on earth, and wave energy has the potential for future power generation. Triboelectric nanogenerator (TENG) technology has recently been proposed as a promising technology to harvest wave energy. In this paper, a theoretical study is performed on a duck-shaped TENG wave harvester recently introduced in our work. To enhance the design of the duck-shaped TENG wave harvester, the mechanical and electrical characteristics of the harvester’s overall structure, as well as its inner configuration, are analyzed, respectively, under different wave conditions, to optimize parameters such as duck radius and mass. Furthermore, a comprehensive hybrid 3D model is introduced to quantify the performance of the TENG wave harvester. Finally, the influence of different TENG parameters is validated by comparing the performance of several existing TENG wave harvesters. This study can be applied as a guideline for enhancing the performance of TENG wave energy harvesters.

    In this completely updated and revised edition of Designing with the Mind in Mind, Jeff Johnson provides you with just enough background in perceptual and cognitive psychology that user interface (UI) design guidelines make intuitive sense rather than being just a list or rules to follow. Early UI practitioners were trained in cognitive psychology, and developed UI design rules based on it. But as the field has evolved since the first edition of this book, designers enter the field from many disciplines. Practitioners today have enough experience in UI design that they have been exposed to

    2012-04-01

    Full Text Available Abstract Background An assessment programme, a purposeful mix of assessment activities, is necessary to achieve a complete picture of assessee competence. High quality assessment programmes exist, however, design requirements for such programmes are still unclear. We developed guidelines for design based on an earlier developed framework which identified areas to be covered. A fitness-for-purpose approach defining quality was adopted to develop and validate guidelines. Methods First, in a brainstorm, ideas were generated, followed by structured interviews with 9 international assessment experts. Then, guidelines were fine-tuned through analysis of the interviews. Finally, validation was based on expert consensus via member checking. Results In total 72 guidelines were developed and in this paper the most salient guidelines are discussed. The guidelines are related and grouped per layer of the framework. Some guidelines were so generic that these are applicable in any design consideration. These are: the principle of proportionality, rationales should underpin each decisions, and requirement of expertise. Logically, many guidelines focus on practical aspects of assessment. Some guidelines were found to be clear and concrete, others were less straightforward and were phrased more as issues for contemplation. Conclusions The set of guidelines is comprehensive and not bound to a specific context or educational approach. From the fitness-for-purpose principle, guidelines are eclectic, requiring expertise judgement to use them appropriately in different contexts. Further validation studies to test practicality are required.

  14. Design guidelines for high dimensional stability of CFRP optical bench

    Desnoyers, Nichola; Boucher, Marc-André; Goyette, Philippe

    2013-09-01

    In carbon fiber reinforced plastic (CFRP) optomechanical structures, particularly when embodying reflective optics, angular stability is critical. Angular stability or warping stability is greatly affected by moisture absorption and thermal gradients. Unfortunately, it is impossible to achieve the perfect laminate and there will always be manufacturing errors in trying to reach a quasi-iso laminate. Some errors, such as those related to the angular position of each ply and the facesheet parallelism (for a bench) can be easily monitored in order to control the stability more adequately. This paper presents warping experiments and finite-element analyses (FEA) obtained from typical optomechanical sandwich structures. Experiments were done using a thermal vacuum chamber to cycle the structures from -40°C to 50°C. Moisture desorption tests were also performed for a number of specific configurations. The selected composite material for the study is the unidirectional prepreg from Tencate M55J/TC410. M55J is a high modulus fiber and TC410 is a new-generation cyanate ester designed for dimensionally stable optical benches. In the studied cases, the main contributors were found to be: the ply angular errors, laminate in-plane parallelism (between 0° ply direction of both facesheets), fiber volume fraction tolerance and joints. Final results show that some tested configurations demonstrated good warping stability. FEA and measurements are in good agreement despite the fact that some defects or fabrication errors remain unpredictable. Design guidelines to maximize the warping stability by taking into account the main dimensional stability contributors, the bench geometry and the optical mount interface are then proposed.

  15. Towards landscape design guidelines for reducing Lyme disease risk.

    2006-04-01

    Incidence of Lyme disease in the US continues to grow. Low-density development is also increasing in endemic regions, raising questions about the relationship between development pattern and disease. This study sought to model Lyme disease incidence rate using quantitative, practical metrics of regional landscape pattern. The objective was to progress towards the development of design guidelines that may help minimize known threats to human and environmental health. Ecological analysis was used to accommodate the integral landscape variables under study. Case data derived from passive surveillance reports across 12 counties in the US state of Maryland during 1996-2000; 2,137 cases were spatially referenced to residential addresses. Major roads were used to delineate 514 landscape analysis units from 0.002 to 580 km(2). The parameter that explained the most variation in incidence rate was the percentage of land-cover edge represented by the adjacency of forest and herbaceous cover [R(2) = 0.75; rate ratio = 1.34 (1.26-1.43); P landscape in forest cover (cumulative R(2) = 0.82), which exhibited a quadratic relationship with incidence rate. Modelled relationships applied throughout the range of landscape sizes. Results begin to provide quantitative landscape design parameters for reducing casual peridomestic contact with tick and host habitat. The final model suggests that clustered forest and herbaceous cover, as opposed to high forest-herbaceous interspersion, would minimize Lyme disease risk in low-density residential areas. Higher-density development that precludes a large percentage of forest-herbaceous edge would also limit exposure.

    Full Text Available There have been numerous studies done on the guidelines of user interface, but only a number of them have considered specific guidelines for the design of children’s interface. This paper is about a research on the specific guidelines for children, focusing on the criteria of graphic design. The objective of this research is to study on the guidelines of user interface design and to develop specific guidelines on children’s graphic design. The criteria of graphic design are the priority of this research since previous research have proven that graphic design is the main factor which contributes to the problem of usability of web application interfaces, in terms of the overall graphic layout not being in a hierarchical order, not taken into concern the availability of space, inappropriate margin, improper type and font size selection, and less concentration on the use of the colours. The research methodology makes use of the comparison of and the coordination to the guidelines on children’s interface and the specific guidelines on the graphic design of web application interfaces. The contribution of this research is the guidelines on the design of web application graphics which are specifically for children.

    Advanced control rooms will use advanced human-system interface (HSI) technologies that may have significant implications for plant safety in that they will affect the operator`s overall role in the system, the method of information presentation, and the ways in which operators interact with the system. The U.S. Nuclear Regulatory Commission (NRC) reviews the HSI aspects of control rooms to ensure that they are designed to good human factors engineering principles and that operator performance and reliability are appropriately supported to protect public health and safety. The principal guidance available to the NRC, however, was developed more than ten years ago, well before these technological changes. Accordingly, the human factors guidance needs to be updated to serve as the basis for NRC review of these advanced designs. The purpose of this project was to develop a general approach to advanced HSI review and the human factors guidelines to support. NRC safety reviews of advanced systems. This two-volume report provides the results of the project. Volume I describes the development of the Advanced HSI Design Review Guideline (DRG) including (1) its theoretical and technical foundation, (2) a general model for the review of advanced HSIs, (3) guideline development in both hard-copy and computer-based versions, and (4) the tests and evaluations performed to develop and validate the DRG. Volume I also includes a discussion of the gaps in available guidance and a methodology for addressing them. Volume 2 provides the guidelines to be used for advanced HSI review and the procedures for their use.

    These metal wastage design guidelines identify relationships between metal wastage and (1) design parameters (such as tube size, tube spacing and pitch, tube bundle and fluidized-bed height to distributor, and heat exchanger tube material properties) and (2) operating parameters (such as fluidizing velocity, particle size, particle hardness, and angularity). The guidelines are of both a quantitative and qualitative nature. Simplified mechanistic models are described, which account for the essential hydrodynamics and metal wastage processes occurring in bubbling fluidized beds. The empirical correlational approach complements the use of these models in the development of these design guidelines. Data used for model and guideline validation are summarized and referenced. Sample calculations and recommended design procedures are included. The influences of dependent variables on metal wastage, such as solids velocity, bubble size, and in-bed pressure fluctuations, are discussed.

    Brown, K.; Sartor, D.; Greenberg, S. [and others

    1996-05-01

    In 1994, the Bay Chapter of the Association of Energy Engineers{reg_sign} organized a two-day design charrette for energy-efficient redevelopment of buildings by the National Park Services (NPS) at the Presidio of San Francisco. This event brought together engineers, researchers, architects, government officials, and students in a participatory environment to apply their experience to create guidelines for the sustainable redesign of Presidio buildings. The venue for the charrette was a representative barracks building located at the Main Post of the Presidio. Examination of this building allowed for the development of design recommendations, both for the building and for the remainder of the facilities. The charrette was organized into a committee structure consisting of: steering, measurement and monitoring, modeling, building envelope and historic preservation (architectural), HVAC and controls, lighting, and presentation. Prior to the charrette itself, the modeling and measurement/monitoring committees developed substantial baseline data for the other committees during the charrette. An integrated design approach was initiated through interaction between the committees during the charrette. Later, committee reports were cross-referenced to emphasize whole building design and systems integration.

    2016-12-01

    Full Text Available It is predicted that the major increase in energy consumption and, thus, carbon emissions, will happen in the developing world. However, in most developing countries the knowledge about energy efficiency, particularly in the building sector, is quite low. Strategies developed for industrialised countries might not be suitable or must be adapted for the very different context of developing countries. This research aims to find energy-efficient and cost-effective building design options for the case of Nepal. Energy-efficient building design is a non-trivial issue involving a number of interdependent design criteria. Particularly, in composite climates, passive design strategies might conflict each other leading to an inefficient building design. This paper explores the energy conservation potential in hotel design for all bioclimatic zones of Nepal using building energy simulation with parametric analysis. Based on extensive field studies, reference models for typical hotel buildings ranging from small-scale resort hotels to large-scale multi-storey hotels were developed. These reference designs were optimised by varying design parameters such as window-to-wall ratio, glazing material, shading devices, glazing type and insulation levels. During the design optimisation, energy demand as well as cost effectiveness were evaluated. Finally, recommendations for energy-efficient and cost-effective hotel design solutions were suggested. In addition, the bioclimatic zoning for Nepal was consolidated leading to five elevation-based zones that can be used to introduce building energy regulations in the future.

    2013-12-01

    Full Text Available Abstract In the books of hadeeth and fiqh, it has been narrated many instructions about the imam and congregation position, especially about the position between the imam and the congregation and about the farthest and highest distance of the last row. Suprisingly, if we look closely, these lead us to the possibility in designing a vertical mosque. That is important to address the problem of urban sprawl, where the buildings would have to be directed vertically to solve urban density and to avoid further loss of urban green space. But, is there any high restriction in the hadeeth and the fiqh? Would it be opposed to other hadeeths about the warning of vying to build a magnificent tall mosque? This paper discussed about the possibility in designing a vertical mosque in terms of islamic fiqh and architecture. The research aimed to create a design guideline for vertical mosque and to correct some misconceptions in designing a mosque. This research used a qualitative method, namely literature review. The outcome of this research is the guidelines in designing a vertical mosque. Keywords: Fiqh, Islamic Architecture, Imam and Congregation, Mosque     Abstrak Dalam buku-buku hadits dan fiqh banyak diriwayatkan petunjuk-petunjuk mengenai posisi imam dan jamaah, terutama tentang posisi antara imam dan jamaah dan tentang jarak terjauh dan tertinggi dari baris shaf terakhir. Ternyata jika dicermati, ini membawa kita kepada kemungkinan dalam merancang sebuah masjid vertikal. Hal ini sangat penting untuk menjawab masalah urban sprawl, di mana bangunan harus diarahkan secara vertikal untuk mengatasi kepadatan kota dan menghindari kehilangan lebih lanjut dari ruang terbuka hijau. Tapi, apakah ada pembatasan tingginya pada hadits dan fiqh? Apakah itu akan bertentangan dengan hadits lain mengenai peringatan berlomba membangun masjid mewah dan tinggi?

    Stephen Siu Yu Lau

    2014-12-01

    Full Text Available This paper examines the architectural and landscape design strategies and intentions for green, open spaces facilities targeting stress alleviation for learning environments such as those of university campuses in a compact urban setting. Literature reviews provide three prevailing perspectives for physical design pedagogical operatives: healing gardens where greenery and plants produce restorative effects; flexible spaces that accommodate functional needs of different activities; and green buildings that incorporate open space as a catalyst for integrated eco-system. Corresponding design approaches (landscape design, spatial design and green design are scrutinized by case study. A comparison of two university campuses with different urban contexts is conducted to identify challenges and opportunities for applying these design approaches. For a compact campus, high-dense surroundings may limit the size of an open space and may handicap circulation and accessibility; on the other side, a small open space may provide its users more intimate contact with natural restorative elements and also a more controllable microclimate for physical comfort. A healthy campus should encompass diverse open spaces to satisfy different purposes. Finally, a framework that integrates the three approaches is combined to produce a sustainable design rubric.

  6. Toward best practice in Human Machine Interface design for older drivers: A review of current design guidelines.

    Science.gov (United States)

    Young, K L; Koppel, S; Charlton, J L

    2017-09-01

    Older adults are the fastest growing segment of the driving population. While there is a strong emphasis for older people to maintain their mobility, the safety of older drivers is a serious community concern. Frailty and declines in a range of age-related sensory, cognitive, and physical impairments can place older drivers at an increased risk of crash-related injuries and death. A number of studies have indicated that in-vehicle technologies such as Advanced Driver Assistance Systems (ADAS) and In-Vehicle Information Systems (IVIS) may provide assistance to older drivers. However, these technologies will only benefit older drivers if their design is congruent with the complex needs and diverse abilities of this driving cohort. The design of ADAS and IVIS is largely informed by automotive Human Machine Interface (HMI) guidelines. However, it is unclear to what extent the declining sensory, cognitive and physical capabilities of older drivers are addressed in the current guidelines. This paper provides a review of key current design guidelines for IVIS and ADAS with respect to the extent they address age-related changes in functional capacities. The review revealed that most of the HMI guidelines do not address design issues related to older driver impairments. In fact, in many guidelines driver age and sensory cognitive and physical impairments are not mentioned at all and where reference is made, it is typically very broad. Prescriptive advice on how to actually design a system so that it addresses the needs and limitations of older drivers is not provided. In order for older drivers to reap the full benefits that in-vehicle technology can afford, it is critical that further work establish how older driver limitations and capabilities can be supported by the system design process, including their inclusion into HMI design guidelines.

    Danion, Gwennaël; Bondu, François; Loas, Goulc'hen; Alouini, Mehdi

    2014-07-15

    This Letter describes the design of an optical amplifier system optimized to reduce the relative intensity noise (RIN) of the input signal, and discloses its performance in terms of intensity noise reduction and bandwidth, without phase noise degradation. This polarization-maintaining amplifier is composed of an erbium-doped fiber amplifier (EDFA) cascaded with a semiconductor optical amplifier (SOA). The EDFA is sized to feed the SOA with a constant power corresponding to the optimal saturation level for noise reduction, through coherent population oscillations. When properly optimized, such an amplifier provides, simultaneously, 17 dB optical gain, 5.4 dB noise factor, and 20 dB reduction of the input-RIN across a 3 GHz bandwidth, without any electronics feedback loop.

    2002-08-15

    Early identification of potential human factors guideline violations and corrective input into the design process are desired for efficient and cost-effective control room design. Virtual reality (VR) technology makes it possible to perform evaluation of the design of the control room at an early stage of the design process, but can we trust the results from such evaluations? This report describes the second phase of an experimental validation of a VR model with virtual verification tools against the real world in a guideline verification task. Results from the previous phase indicated that guideline verification in the VR model could be done with satisfactory accuracy for a number of evaluations. However, some guideline categories required further development of measurement tools and use of a model with higher resolution. To correct the shortcomings and utilize the knowledge from the previous experiment, a number of new features were implemented into the virtual environment used for testing. Results from the test indicate that the detailed modelling of operating panels was helpful. The addition of tools for measuring font sizes and direct illumination also proved useful. However, further refinement is needed in the usability of some of the tools. It is recommended to continue the fine-tuning of these tools, and that a test is made with a physical mockup in a real refurbishment project to get a more authentic test of the virtual verification tools.

    Long hours of static work with awkward posture at traditionally designed looms can cause high prevalence of musculoskeletal disorders (MSDs) among carpet weavers. A comprehensive study was conducted in this industry with the objectives of determination of MSDs symptoms prevalence; identification of major factors associated with MSDs symptoms in carpet weaving occupation; and development of guidelines for weaving workstation design. In the present paper, this ergonomics study is presented. The study consisted of two phases. In the first phase, MSDs symptoms in nine Iranian provinces were surveyed by questionnaire among 1439 randomly selected weavers. Working posture and weaving workstations were ergonomically assessed as well. The results of this phase revealed that symptoms from the musculoskeletal system occurred in high rate among weavers with the prevalence significantly higher than that of the general Iranian population (Pweaving workstation. Based on the findings, some general guidelines for workstation design were presented. In the second phase, considering the general guidelines, an adjustable workstation was designed and constructed. To develop quantitative guidelines for optimizing workstation set-up, in the laboratory, nine sets of experimental conditions were tested, and working posture and weavers' perceptions were measured. The results of this lab work showed that working posture was acceptable for both the researchers and the weavers when the weaving height was adjusted 20 cm above the elbow height and a high seat with forward slope was used. By combining the results of the two phases, guidelines for weaving workstation design were presented. In this ergonomics-oriented workstation, loom is vertical. Seat, loom and weaving heights are adjustable. There is enough leg room under the loom. The seat with 10 degrees forward slope is adjusted 15 cm above the popliteal height of the weaver. Weaving height is set at 20 cm above the elbow height. It is

    The IAEA Regulations for the Safe Transport of Radioactive Material, TS-R-1 are applied in Germany through the implementation of the Dangerous Goods Transport Regulations for class 7 of the International Modal Organisations (ADR, RID, IMDG-Code, ICAO-TI). Based on this the approval procedures for packages designs applied in Germany are in compliance with the provisions of TS-R-1. The Guideline R 003 issued by the Ministry of Transport, Building and Housing (BMVBW) in 1991 is the basis for the package design approval procedures in Germany. This Guideline has been reviewed and revised to reflect latest developments in the regulations as well as in the regulatory practice. In particular it has been extended to the approval procedures of Type C packages, packages subject to transitional arrangements, special form and low dispersible radioactive material and provides more detailed information to the applicant about the requested documentation. Publication of this revised guideline has been delayed but it is expected to take place in October 2004. The paper gives an overview about the main parts and provisions of this revised Guideline R 003 with the focus on package design approval procedures.

    1990-06-01

    The Department of Energy (DOE) and the DOE Natural Phenomena Hazards Panel have developed uniform design and evaluation guidelines for protection against natural phenomena hazards at DOE sites throughout the United States. The goal of the guidelines is to assure that DOE facilities can withstand the effects of natural phenomena such as earthquakes, extreme winds, tornadoes, and flooding. The guidelines apply to both new facilities (design) and existing facilities (evaluation, modification, and upgrading). The intended audience is primarily the civil/structural or mechanical engineers conducting the design or evaluation of DOE facilities. The likelihood of occurrence of natural phenomena hazards at each DOE site has been evaluated by the DOE Natural Phenomena Hazard Program. Probabilistic hazard models are available for earthquake, extreme wind/tornado, and flood. Alternatively, site organizations are encouraged to develop site-specific hazard models utilizing the most recent information and techniques available. In this document, performance goals and natural hazard levels are expressed in probabilistic terms, and design and evaluation procedures are presented in deterministic terms. Design/evaluation procedures conform closely to common standard practices so that the procedures will be easily understood by most engineers. Performance goals are expressed in terms of structure or equipment damage to the extent that: (1) the facility cannot function; (2) the facility would need to be replaced; or (3) personnel are endangered. 82 refs., 12 figs., 18 tabs.

    Basic toxicological information is lacking for the majority of industrial chemicals. In addition to increasing empirical toxicity data through additional testing, prospective computational approaches to drug development aim to serve as a rational basis for the design of chemicals with reduced toxicity. Recent work has resulted in the derivation of a "rule of 2," wherein chemicals with an octanol-water partition coefficient (log P) less than 2 and a difference between the lowest unoccupied molecular orbital and the highest occupied molecular orbital (ΔE) greater than 9 (log P9 eV) are predicted to be 4 to 5 times less likely to elicit acute or chronic toxicity to model aquatic organisms. The present study examines potential reduction of aquatic toxicity hazards from industrial chemicals if these 2 molecular design guidelines were employed. Probabilistic hazard assessment approaches were used to model the likelihood of encountering industrial chemicals exceeding toxicological categories of concern both with and without the rule of 2. Modeling predicted that utilization of these molecular design guidelines for log P and ΔE would appreciably decrease the number of chemicals that would be designated to be of "high" and "very high" concern for acute and chronic toxicity to standard model aquatic organisms and end points as defined by the US Environmental Protection Agency. For example, 14.5% of chemicals were categorized as having high and very high acute toxicity to the fathead minnow model, whereas only 3.3% of chemicals conforming to the design guidelines were predicted to be in these categories. Considerations of specific chemical classes (e.g., aldehydes), chemical attributes (e.g., ionization), and adverse outcome pathways in representative species (e.g., receptor-mediated responses) could be used to derive future property guidelines for broader classes of contaminants.

    Lake, Mark S.; Hachkowski, M. Roman

    2000-01-01

    This paper is intended to facilitate the development of deployable, optical instruments by providing a rational approach for the design, testing, and qualification of high-precision (i.e., low-hysteresis) deployment mechanisms for these instruments. Many of the guidelines included herein come directly from the field of optomechanical engineering, and are, therefore, neither newly developed guidelines, nor are they uniquely applicable to the design of high-precision deployment mechanisms. This paper is to be regarded as a guide to design and not a set of NASA requirements, except as may be defined in formal project specifications. Furthermore, due to the rapid pace of advancement in the field of precision deployment, this paper should be regarded as a preliminary set of guidelines. However, it is expected that this paper, with revisions as experience may indicate to be desirable, might eventually form the basis for a set of uniform design requirements for high-precision deployment mechanisms on future NASA space-based science instruments.

    This paper presents some design guidelines for a new voltage fed step-up DC/DC isolated converter. The most significant advantage of proposed converter is voltage buck-boost operation on single stage. The most promising application for proposed converter is in the field of distributed power generation e.g. fuel cells or photovoltaic. The most sensitive issues - such as power losses caused by high currents in the input side of converter and high transient overvoltages across the inverter bridge caused by stray inductances were discussed and solved. The proposals and recommendations to overcome these issues are given in the paper. The Selection and design guidelines of converter elements are proposed and explained. The prototype of proposed converter was built and experimentally tested. Some results are presented and evaluated.

    Full Text Available Abstract Background Computerized ICUs rely on software services to convey the medical condition of their patients as well as assisting the staff in taking treatment decisions. Such services are useful for following clinical guidelines quickly and accurately. However, the development of services is often time-consuming and error-prone. Consequently, many care-related activities are still conducted based on manually constructed guidelines. These are often ambiguous, which leads to unnecessary variations in treatments and costs. The goal of this paper is to present a semi-automatic verification and translation framework capable of turning manually constructed diagrams into ready-to-use programs. This framework combines the strengths of the manual and service-oriented approaches while decreasing their disadvantages. The aim is to close the gap in communication between the IT and the medical domain. This leads to a less time-consuming and error-prone development phase and a shorter clinical evaluation phase. Methods A framework is proposed that semi-automatically translates a clinical guideline, expressed as an XML-based flow chart, into a Drools Rule Flow by employing semantic technologies such as ontologies and SWRL. An overview of the architecture is given and all the technology choices are thoroughly motivated. Finally, it is shown how this framework can be integrated into a service-oriented architecture (SOA. Results The applicability of the Drools Rule language to express clinical guidelines is evaluated by translating an example guideline, namely the sedation protocol used for the anaesthetization of patients, to a Drools Rule Flow and executing and deploying this Rule-based application as a part of a SOA. The results show that the performance of Drools is comparable to other technologies such as Web Services and increases with the number of decision nodes present in the Rule Flow. Most delays are introduced by loading the Rule Flows

    Background/Aim: Studies have indicated a relationship between either gene polymorphism or in vivo B vitamins’ nutritional status with cognition in the elderly. However, the combined effects of MTHFR and SLC19A1gene polymorphism with serum folate and vitamin B12 levels on cognition in Chinese adult population remain unclear. Methods: Demographic information of 426 Chinese adults aged from 55 to 90 were collected by a well designed self-administered questionnaire. The Montreal Cognitive Assessment test was utilized to evaluate the cognition status of the participants. MTHFR and SLC19A1 genotyping was analyzed using polymerase chain reaction-ligase detection reaction (PCR- LDR) method. Serum folate, vitamin B12 and homocysteine (Hcy) levels were detected by commercial assay kits. Pearson’s correlation was used for data analyses and statistical significance was set at p vitamin B12 (r = −0.292) levels. The negative correlation found between serum Hcy levels and attention ability was observed in all 426 studied subjects (r = −0.122). Subjects with MTHFR 677 T/T and 1298 A/A genotypes demonstrated a higher serum Hcy levels (p vitamin B12. Conclusion: Cognition of adults was associated with MTHFR, SLC19A1 gene polymorphism and serum Hcy levels. This study clearly establishes a combined effect of MTHFR gene polymorphism and serum B vitamins levels on cognition in Chinese adults. PMID:27783031

    Advanced human-system interface (HSI) technologies are being developed in the commercial nuclear power industry. These HSIs may have significant implications for plant safety in that they will affect the ways in which the operator interacts with and supervises an increasingly complex system. The U.S. Nuclear Regulatory Commission (NRC) reviews the HSI aspects of nuclear plants to ensure that operator performance and reliability are supported. The NRC is developing guidance to support its review of these advanced designs. The guidance consists of an evaluation methodology and an extensive set of human factors guidelines which are used in one aspect of the evaluation. The paper describes the guidance development of the evaluation methodology and the guidelines.

  12. Passive solar design strategies: Remodeling guidelines for conserving energy at home. [Final report

    Energy Technology Data Exchange (ETDEWEB)

    1991-12-31

    The idea of passive solar is simple, but applying it effectively does require information and attention to the details of design and construction. Some passive solar techniques are modest and low-cost, and require only small changes in remodeler`s typical practice. At the other end of the spectrum, some passive solar systems can almost eliminate a house`s need for purchased heating (and in some cases, cooling) energy -- but probably at a relatively high first cost. In between are a broad range of energy-conserving passive solar techniques. Whether or not they are cost-effective, practical and attractive enough to offer a market advantage to any individual remodeler depends on very specific factors such as local costs, climate, and market characteristics. Passive solar design strategies: Remodeling Guidelines For Conserving Energy At Homes is written to help give remodelers the information they need to make these decisions. Passive Solar Design Strategies is a package in three basic parts: The Guidelines contain information about passive solar techniques and how they work, and provides specific examples of systems which will save various percentages of energy; The Worksheets offer a simple, fill-in-the-blank method to pre-evaluate the performance of a specific design; The Worked Example demonstrates how to complete the worksheets for a typical residence.

    1979-01-01

    Individual Spacelab experiments are responsible for developing their CRT display formats and interactive command scenarios for payload crew monitoring and control of experiment operations via the Spacelab Data Display System (DDS). In order to enhance crew training and flight operations, it was important to establish some standardization of the crew/experiment interface among different experiments by providing standard methods and techniques for data presentation and experiment commanding via the DDS. In order to establish optimum usage guidelines for the Spacelab DDS, the capabilities and limitations of the hardware and Experiment Computer Operating System design had to be considered. Since the operating system software and hardware design had already been established, the Display and Command Usage Guidelines were constrained to the capabilities of the existing system design. Empirical evaluations were conducted on a DDS simulator to determine optimum operator/system interface utilization of the system capabilities. Display parameters such as information location, display density, data organization, status presentation and dynamic update effects were evaluated in terms of response times and error rates.

    Guidelines are presented for use as a tool by those considering application of a new technology, aquifer thermal energy storage (ATES). The guidelines will assist utilities, municipalities, industries, and other entities in the conceptual design and evaluation of systems employing ATES. The potential benefits of ATES are described, an overview is presented of the technology and its applications, and rules of thumb are provided for quickly judging whether a proposed project has sufficient promise to warrant detailed conceptual design and evaluation. The characteristics of sources and end uses of heat and chill which are seasonally mismatched and may benefit from ATES (industrial waste heat, cogeneration, solar heat, and winter chill, for space heating and air conditioning) are discussed. Storage and transport subsystems and their expected performance and cost are described. A 10-step methodology is presented for conceptual design of an ATES system and evaluation of its technical and economic feasibility in terms of energy conservation, cost savings, fuel substitution, improved dependability of supply, and abatement of pollution, with examples, and the methodology is applied to a hypothetical proposed ATES system, to illustrate its use.

    Dynamics of the driveline and the vehicle during clutch engagement is a complex phenomenon. Time domain analysis of different state variables is performed through numerical solution of sixth-order driveline model using an indigenous computer program. The study revealed that different design objectives like driver and passenger comfort, smoothness of engagement, wear of friction surfaces, power loss, and heat generation are in mutual conflict, with respect to the sub-ranges of operational parameters. The overall outcome of this study is presented in the form of a matrix, relating the sub-ranges of operational parameters with engagement quality parameters, which may be used as a guideline for clutch design for different design objectives. The engagement quality parameters may also be used for building a cost function for overall optimization of clutch.

    A logical next step in the evolution of the computer-user interface is the incorporation of sound thereby using our senses of ''hearing'' in our communication with the computer. This allows our visual and auditory capacities to work in unison leading to a more effective and efficient interpretation of information received from the computer than by sight alone. In this paper we examine earcons, which are audio cues, used in the computer-user interface to provide information and feedback to the user about computer entities (these include messages and functions, as well as states and labels). The material in this paper is part of a larger study that recommends guidelines for the design and use of audio cues in the computer-user interface. The complete work examines the disciplines of music, psychology, communication theory, advertising, and psychoacoustics to discover how sound is utilized and analyzed in those areas. The resulting information is organized according to the theory of semiotics, the theory of signs, into the syntax, semantics, and pragmatics of communication by sound. Here we present design guidelines for the syntax of earcons. Earcons are constructed from motives, short sequences of notes with a specific rhythm and pitch, embellished by timbre, dynamics, and register. Compound earcons and family earcons are introduced. These are related motives that serve to identify a family of related cues. Examples of earcons are given.

  5. Development of guidelines for improved hydraulic design of waste stabilisation ponds.

    Shilton, A; Harrison, J

    2003-01-01

    Pond hydraulic behaviour is influenced by the inlet/outlet configuration, baffles and wind, but design information relating to these factors is still very limited. This paper reviews the development of "Guidelines for the Improved Hydraulic Design of Waste Stabilisation Ponds" and summarises some of the key findings and recommendations. This work was based on review of previous research, laboratory experimentation, field studies and mathematical modelling using computational fluid dynamics. The inlet design can have a significant influence on the flow regime in a pond. Poorly considered positioning of the inlet and the outlet can create hydraulic short-circuiting problems. As an example of the nature of the work undertaken in this project, the use of a small horizontal inlet pipe was compared against a vertical inlet design. A practical method of assessing the relative significance of wind versus inlet power input was presented. The application of this analysis may allow engineers to size inlet pipes to help control the flow patterns in ponds for efficient performance. Extensive testing has been undertaken on a wide range of baffle configurations. An example of this research showed how short stub baffles could provide similar improvements to longer "traditional" baffle designs, potentially offering significant savings in construction costs. For traditional baffle designs a minimum of two baffles is recommended. For the pond modelled in this work, it was found that any more than four baffles gave only marginal improvements.

  6. Guidelines for designing 2D and 3D plasmonic stub resonators

    2016-01-01

    In this work we compare the performance of plasmonic waveguide integrated stub resonators based on 2D metal-dielectric-metal (MDM) and 3D slot-waveguide (SWG) geometries. We show that scattering matrix theory can be extended to 3D devices, and by employing scattering matrix theory we provide the guidelines for designing plasmonic 2D and 3D single-stub and double-stub resonators with a desired spectral response at the design wavelength. We provide transmission maps of 2D and 3D double-stub resonators versus stub lengths, and we specify the different regions on these maps that result in a minimum, a maximum or a plasmonically induced transparency (PIT) shape in the transmission spectrum. Radiation loss from waveguide terminations leads to a degradation of the 3D slot-waveguide based resonators. We illustrate improved waveguide terminations that boost resonator properties. We verify our results with 3D FDTD simulations.

    Full Text Available DNA methylation is an epigenetic regulation mechanism of genomic function, and aberrant methylation pattern has been found to be a common event in many diseases and human cancers. A large number of cancer studies have been focused on identification of methylation changes as biomarkers (i.e., breast cancer. However, still clinical use of them is very limited because of lack of specificity and sensitivity for diagnostic test. This highlights the critical need for specific primer and probe design to avoid false-positive detection of methylation profiling. The guideline and online web tools that are introduced in this paper might help to perform a successful experiment and to develop specific diagnosis biomarkers by designing right primer pair and probe prior to experimental step.

  8. Bridging Theory and Practice: Developing Guidelines to Facilitate the Design of Computer-based Learning Environments

    Directory of Open Access Journals (Sweden)

    Lisa D. Young

    2003-10-01

    Full Text Available Abstract. The design of computer-based learning environments has undergone a paradigm shift; moving students away from instruction that was considered to promote technical rationality grounded in objectivism, to the application of computers to create cognitive tools utilized in constructivist environments. The goal of the resulting computer-based learning environment design principles is to have students learn with technology, rather than from technology. This paper reviews the general constructivist theory that has guided the development of these environments, and offers suggestions for the adaptation of modest, generic guidelines, not mandated principles, that can be flexibly applied and allow for the expression of true constructivist ideals in online learning environments.

  9. Facing up to the Plurality of Goals, Methods, Needs and Resources in HCI

    Directory of Open Access Journals (Sweden)

    Stephen Draper

    1996-05-01

    Full Text Available Most analyses of how humans use artifacts, and interactive software in particular, have a strong tendency to assign 1:1 correspondences between goals and methods: to see software as supporting one task, users as having one way of executing a task, one thing to learn when learning a command, and one source for discovering the information. In fact this is a rare case, and multiplicity of goals, methods, information needs, and information resources is the rule even in simple software. How this causes problems for the design and testing of user interfaces can be illustrated by examples from a wide range of domains and levels of design, including studies on learning by exploration, the effect of machine delays on user strategies, the Icamability of icon sets, evaluation studies of Computer Assisted Learning, and an analysis of the concept of affordance. Such plurality can he a source of robustness for the performance of interfaces: it is a problem main for analysis and HCI research, which struggle to account for the frequent case of high average performance levels mixed with a few residual problems. To address this plurality, we must extend our analyses to cover sets of alternative methods for tasks rather than single user procedures, and perhaps draw on concepts such as Activity Theory to address users' mental organisation of such plurality.

    The objective of this study is to develop human factors engineering program review guidelines and alarm system review guidelines in order to resolve the two major technical issues: '25. Human Factors Engineering Program Review Model' and '26. Review Criteria for Human Factors Aspects of Advanced Controls and Instrumentation', which are related to the development of human factors safety regulation guides being performed by KINS. For the development of human factors program review guidelines, we made a Korean version of NUREG-0711 and added our comments by considering Korean regulatory situation and the characteristics of the KNGR design, and reviewing the reference documents of NURGE-0711. We also computerized the Korean version of NUREG-0711, additional comments, and selected portion of the reference documents for the developer of safety regulation guides at KINS to see the contents comparatively at a glance and use them easily. For the development of alarm system design review guidelines, we made a Korean version of NUREG/CR-6105, which was published by NRC in 1994 as a guideline document for the human factors review of alarm systems. Then we updated the guidelines by reviewing the literature related to alarm design that published after 1994. 12 refs., 11 figs., 2 tabs. (Author)

    Although it is generally accepted that the use of adhesives in the assembly of hybrid microcircuits offers advantages over other bonding methods, there currently does not exist a set of guidelines for the selection of adhesives which will insure that hybrid microcircuits assembled with them will meet the long use-life, high-reliability requirements of electronic equipment for space applications. This study was directed to the identification of the properties of electrically insulative adhesives that potentially could cause problems in such an application, and to the development of evaluation tests to quantify these properties and thus form the basis for establishing suitable guidelines and, ultimately, specifications. Bond strength, outgassing after cure, and corrosivity were selected for detailed attention since they are considered to be especially critical. Introductory discussion includes enumeration and brief comments on the properties of adhesives considered to be important for the proposed application, a general review of polymeric types of adhesives, and identification of the major types of adhesives commercially available and specifically designed for microelectronic use. The specific tests developed to evaluate bond strength, outgassing after cure, and corrosivity are discussed in detail, and comparative results obtained for selected adhesives representative of the major types are given.

    Physical inactivity is a leading cause of death in the United States and globally and is also associated with several additional leading causes of death, including obesity, high blood pressure and high blood glucose. The built environment plays a critical role in promoting or discouraging physical activity among adults and children. To create a healthier and more physically active city, a working group comprising several New York City agencies, including the Departments of Design and Construction, Health and Mental Hygiene, Transportation and City Planning, and in collaboration with design organizations and academics, published the Active Design Guidelines (ADG; ) in January 2010. The ADG is a manual of evidence-based and best-practice strategies for increasing physical activity in the design and construction of neighborhoods, streets and buildings. The commentary discusses key activities and events leading up to the publication as well as current implementation activities. It also shares the lessons learned that could assist other communities interested in improving their built environments in developing and implementing similar activities and initiatives.

    Full Text Available Abstract Background Opioid prescribing for chronic pain is common and controversial, but recommended clinical practices are followed inconsistently in many clinical settings. Strategies for increasing adherence to clinical practice guideline recommendations are needed to increase effectiveness and reduce negative consequences of opioid prescribing in chronic pain patients. Methods Here we describe the process and outcomes of a project to operationalize the 2003 VA/DOD Clinical Practice Guideline for Opioid Therapy for Chronic Non-Cancer Pain into a computerized decision support system (DSS to encourage good opioid prescribing practices during primary care visits. We based the DSS on the existing ATHENA-DSS. We used an iterative process of design, testing, and revision of the DSS by a diverse team including guideline authors, medical informatics experts, clinical content experts, and end-users to convert the written clinical practice guideline into a computable algorithm to generate patient-specific recommendations for care based upon existing information in the electronic medical record (EMR, and a set of clinical tools. Results The iterative revision process identified numerous and varied problems with the initially designed system despite diverse expert participation in the design process. The process of operationalizing the guideline identified areas in which the guideline was vague, left decisions to clinical judgment, or required clarification of detail to insure safe clinical implementation. The revisions led to workable solutions to problems, defined the limits of the DSS and its utility in clinical practice, improved integration into clinical workflow, and improved the clarity and accuracy of system recommendations and tools. Conclusions Use of this iterative process led to development of a multifunctional DSS that met the approval of the clinical practice guideline authors, content experts, and clinicians involved in testing.

    2010-01-01

    A majority of original articles published in biomedical journals include some form of statistical analysis. Unfortunately, many of the articles contain errors in statistical design and/or analysis. These errors are worrisome, as the misuse of statistics jeopardizes the process of scientific discovery and the accumulation of scientific knowledge. To help avoid these errors and improve statistical reporting, four approaches are suggested: (1) development of guidelines for statistical reporting that could be adopted by all journals, (2) improvement in statistics curricula in biomedical research programs with an emphasis on hands-on teaching by biostatisticians, (3) expansion and enhancement of biomedical science curricula in statistics programs, and (4) increased participation of biostatisticians in the peer review process along with the adoption of more rigorous journal editorial policies regarding statistics. In this chapter, we provide an overview of these issues with emphasis to the field of molecular biology and highlight the need for continuing efforts on all fronts.

    The phase locked-loops (PLLs) are probably the most widely used synchronization technique in grid-connected applications. The main challenge associated with the PLLs is how to precisely and fast estimate the phase and frequency when the grid voltage is unbalanced and/or distorted. To overcome...... this challenge, incorporating moving average filter(s) (MAF) into the PLL structure has been proposed in some recent literature. A MAF is a linear-phase finite impulse response filter which can act as an ideal low-pass filter, if certain conditions hold. The main aim of this paper is to present the control...... design guidelines for a typical MAF-based PLL. The paper starts with the general description of MAFs. The main challenge associated with using the MAFs is then explained, and its possible solutions are discussed. The paper then proceeds with a brief overview of the different MAF-based PLLs. In each case...

    2016-10-01

    Space debris presents an increasing threat to the lifetime of commercial and military space assets. Laser-based space debris removal systems could potentially mitigate this threat by targeting debris objects in the cm-range. In order to reach this goal a minimum fluence of a few J/cm² on the debris object and a pulse repetition rate of several 10 Hz are necessary. These requirements can be met by coupling 1000-2000 independent 10 J laser sources coherently and employing a sending telescope with a diameter of 5 m. We analyze which parameters are critical to the effectiveness of the transmission system and deduce design guidelines. In particular the effects of non-optimum filling factors, secondary mirror size, emitter intensity distribution and phase jitter of the individual emitters are discussed and compared.

    Cowell, Andrew J.; Stanney, Kay M.; Thomas Rist

    2003-09-01

    This paper discusses our recent studies on Embodied Conversational Agent (ECA) design strategies. We attack the problem from two specific directions, that is, via the embodiment that the character wears during its relations with the user, and the method of interaction used by the ECA to engage the user in a dialogue. A rigorous literature review lead to a set of hypotheses that were empirically validated. Our results indicate that while users generally prefer to interact with a young character matching their ethnicity, no significant preference were indicated for character gender. For interaction, our results indicated that there were no significant differences in perceived trust between the facial and facial/body treatments (suggesting there is little utility in adding gesture and posture behaviors to an interaction scheme) although both were rated much higher than the non-trusting treatment. Other interesting results (e.g. people with a high propensity to trust were more trustworthy across treatments, users that interacted with the non-trusting character made more mistakes, disliked the interaction and felt less in control than users in the other treatments) from this work are also discussed.

    Full Text Available Healing gardens are green spaces designed to promote and improve health and well-being for people suffering from illness. This paper proposes a methodology for defining a master plan for healing gardens. The methodology is based on site analysis (identification, limitations and potentials of the area and the evaluation of user needs (patients, staff, relatives. The aim of the master plan is to provide guidelines for the definition of the executive plan, and to set up a sufficiently flexible project suitable for future new categories of patients, according to the different needs of the regional health authorities. The methodology has been applied to a case study: this paper considers the design of the healing garden of a building named Villa Bianca, part of the wider complex of the clinic for mental disorders Villa di Salute located in Trofarello (in the province of Turin, Piedmont, Italy. The main kinds of disturbances treated at Villa di Salute are schizophrenia and personality disorders; there are also some patients with severe depression. At the present time the building and the garden of Villa Bianca are not being used and are undergoing renovation.

    2005-01-01

    Aerodynamic characteristics such as the flow patterns, velocity field, streamline evolutions, characteristic flow modes and characteristic flow regimes of the push-pull ventilation system are cross-examined by using the laser-light sheet smoked-flow visualization method and laser Doppler velocimetry. Four characteristic flow modes, which are denoted as dispersion, transition, encapsulation and strong suction, are identified in the domain of the push-jet and pull-flow velocities at various open-surface tank widths and rising gas velocities. It is argued phenomenologically, from the aerodynamic point of view, that operating the system in the strong suction regime would be a better strategy than operating it in other characteristic regimes for the consideration of capture efficiency. Design guidelines are developed and summarized based on the results obtained from this study. The regression formulas for calculating the critical values of the push-jet and the pull-flow velocities are provided for easy access. The sulfur hexafluoride tracer gas validation technique is performed to measure the capture efficiency. The results of tracer gas validations are consistent with those obtained from the aerodynamic visualization and measurements. The operation points obtained by employing the American Conference of Governmental Industrial Hygienists design criteria are compared with the results obtained in this study for both the aerodynamics and the capture efficiency. Methods for improving the capture efficiency and energy consumptions are suggested.

    2014-01-01

    Clinical guidelines, such as the Integrated Management of Childhood Illness (IMCI), are used worldwide to support community health workers in the assessment of severely ill children. These guidelines are distributed in paper form, complicating their use at the point-of-care. We have developed a framework for building advanced clinical guideline applications for the Android mobile phone OS. The framework transfers clinical guidelines into a flexible and interactive electronic format using an XML interpreter. The resulting application supports intuitive navigation of guidelines while assessing the patient, easy integration of patient management tools, and logging of performed assessments and treatments. The novel approach transforms clinical guidelines from a mere paper dictionary into a working tool that integrates into the daily workflow of community health workers and simplifies their task at the care and administrative levels.

  3. Clinical trial designs of new medicinal products for treating schizophrenia: discussion of EMA's Guideline and a Better Long Term Trial Design

    Directory of Open Access Journals (Sweden)

    Haibiao Jiang

    Full Text Available Background and Objectives: Schizophrenia is a severe chronic disease. Endpoint variables lack objectivity and the diagnostic criteria have evolved with time. In order to guide the development of new drugs, European Medicines Agency (EMA issued a guideline on the clinical investigation of medicinal products for the treatment of schizophrenia. Methods: Authors reviewed and discussed the efficacy trial part of the Guideline. Results: The Guideline divides clinical efficacy trials into short-term trials and long-term trials. The short-term three-arm trial is recommended to replace the short-term two-arm active-controlled non-inferiority trial because the latter has sensitivity issues. The Guideline ultimately makes that three-arm trial a superiority trial. The Guideline discusses four types of long-term trial designs. The randomized withdrawal trial design has some disadvantages. Long-term two-arm active-controlled non-inferiority trial is not recommended due to the sensitivity issue. Extension of the short-term trial is only suitable for extension of the short-term two-arm active-controlled superiority trial. The Guideline suggests that a hybrid design of a randomized withdrawal trial incorporated into a long-term parallel trial might be optimal. However, such a design has some disadvantages and might be too complex to be carried out. Authors suggest instead a three-group long-term trial design, which could provide comparison between test drug and active comparator along with comparison between the test drug and placebo. This alternative could arguably be much easier to carry out compared with the hybrid design. Conclusions: The three-group long-term design merits further discussion and evaluation.

    Full Text Available Quality design and appropriate space organization in preschool settings can support preschool children's educational activities. Although the relationship between the well-being and development of children and physical settings has been emphasized by many early childhood researchers, there is still a need for theoretical design guidelines that are geared towards the improvement of this issue. This research focuses on High/Scope education and aims to shape a theoretical guideline that raises teachers' awareness about the potential of learning spaces and guides them to improve the quality of the physical spaces. To create a theoretical framework, reliable sources are investigated in the light of High/Scope education and the requirements of pre-school children educational spaces. Physical space characteristics, the preschool child's requirements and High/Scope methodology identified design inputs, design considerations and recommendations that shape the final guideline for spatial arrangement in a High/Scope setting are integrated. Discussions and suggestions in this research benefit both designers and High/ Scope teaching staff. Results help High/Scope teaching staff increase the quality of a space in an educational setting without having an architectural background. The theoretical framework of the research allows designers to consider key features and users' possible activities in High/ Scope settings and shape their designs accordingly.

    2014-12-01

    In a previous publication [I. J. Maasilta, AIP Advances 1, 041704 (2011)], we discussed the formalism and some computational results for phononic thermal conduction in the suspended membrane geometry for radial heat flow from a central source, which is a common geometry for some low-temperature detectors, for example. We studied the case where only diffusive surface scattering is present, the so called Casimir limit, which can be experimentally relevant at temperatures below ˜ 10 K in typical materials, and even higher for ultrathin samples. Here, we extend our studies to much thinner membranes, obtaining numerical results for geometries which are more typical in experiments. In addition, we interpret the results in terms of the small signal and differential thermal conductance, so that guidelines for designing devices, such as low-temperature bolometric detectors, are more easily obtained. Scaling with membrane dimensions is shown to differ significantly from the bulk scattering, and, in particular, thinning the membrane is shown to lead to a much stronger reduction in thermal conductance than what one would envision from the simplest bulk formulas.

  16. Factors controlling volume errors through 2D gully erosion assessment: guidelines for optimal survey design

    Science.gov (United States)

    Castillo, Carlos; Pérez, Rafael

    2017-04-01

    The assessment of gully erosion volumes is essential for the quantification of soil losses derived from this relevant degradation process. Traditionally, 2D and 3D approaches has been applied for this purpose (Casalí et al., 2006). Although innovative 3D approaches have recently been proposed for gully volume quantification, a renewed interest can be found in literature regarding the useful information that cross-section analysis still provides in gully erosion research. Moreover, the application of methods based on 2D approaches can be the most cost-effective approach in many situations such as preliminary studies with low accuracy requirements or surveys under time or budget constraints. The main aim of this work is to examine the key factors controlling volume error variability in 2D gully assessment by means of a stochastic experiment involving a Monte Carlo analysis over synthetic gully profiles in order to 1) contribute to a better understanding of the drivers and magnitude of gully erosion 2D-surveys uncertainty and 2) provide guidelines for optimal survey designs. Owing to the stochastic properties of error generation in 2D volume assessment, a statistical approach was followed to generate a large and significant set of gully reach configurations to evaluate quantitatively the influence of the main factors controlling the uncertainty of the volume assessment. For this purpose, a simulation algorithm in Matlab® code was written, involving the following stages: - Generation of synthetic gully area profiles with different degrees of complexity (characterized by the cross-section variability) - Simulation of field measurements characterised by a survey intensity and the precision of the measurement method - Quantification of the volume error uncertainty as a function of the key factors In this communication we will present the relationships between volume error and the studied factors and propose guidelines for 2D field surveys based on the minimal survey

    2016-04-01

    Full Text Available Recently, Service Level Agreement (SLA and green SLA (GSLA becomes very important for both the service providers/vendors and as well as for the users/customers. There are many ways to inform users/customers about various services with its inherent execution functionalities and even non-functional/Quality of Service (QoS aspects through SLAs. However, these basic SLAs actually do not cover eco-efficient green issues or IT ethics issues for sustainable development. That is why green SLA (GSLA already came into play for achieving sustainability in the industry. Nevertheless, the current practice of GSLA in the industry do not respect the sustainability at all. GSLA defined as a formal agreement incorporating all the traditional commitments respecting some green computing parameters such as carbon footprint, energy consumption etc. Therefore, there are still gaps for achieving sustainability through existing GSLA. To reach the goal of achieving sustainability and getting more customers, many IT (Information Technology and ICT (Information and Communication Technology business are looking for a real GSLA which would meet the ecological, economical and ethical aspects (3Es of sustainability. This research discovers the missing parameters and introduce new parameters under sustainability hoods. In addition, it defines GSLA of sustainability with new green performance indicators and their measurable units. It also discovers the management complexity of proposed new GSLA through designing a general informational model and identifies various new entities and their effects with other entities under three pillars of sustainability. The ICT engineer could use the informational model as a guideline to design a sustainable GSLA for the industry. Therefore, the proposed model could help different service providers/vendors to define their future business strategies for the upcoming sustainable society.

    1995-10-01

    This document provides seismic design and evaluation guidelines for underground high-level waste storage tanks. The guidelines reflect the knowledge acquired in the last two decades in defining seismic ground motion and calculating hydrodynamic loads, dynamic soil pressures and other loads for underground tank structures, piping and equipment. The application of the guidelines is illustrated with examples. The guidelines are developed for a specific design of underground storage tanks, namely double-shell structures. However, the methodology discussed is applicable for other types of tank structures as well. The application of these and of suitably adjusted versions of these concepts to other structural types will be addressed in a future version of this document. The original version of this document was published in January 1993. Since then, additional studies have been performed in several areas and the results are included in this revision. Comments received from the users are also addressed. Fundamental concepts supporting the basic seismic criteria contained in the original version have since then been incorporated and published in DOE-STD-1020-94 and its technical basis documents. This information has been deleted in the current revision.

    The objectives of this study were to (a) review electronic medical record (EMR) and related electronic health record (EHR) interface usability issues, (b) review how EMRs have been evaluated with safety analysis techniques along with any hazard recognition, and (c) formulate design guidelines and a concept for enhanced EMR interfaces with a focus on diagnosis and documentation processes. A major impact of information technology in health care has been the introduction of EMRs. Although numerous studies indicate use of EMRs to increase health care quality, there remain concerns with usability issues and safety. A literature search was conducted using Compendex, PubMed, CINAHL, and Web of Science databases to find EMR research published since 2000. Inclusion criteria included relevant English-language papers with subsets of keywords and any studies (manually) identified with a focus on EMR usability. Fifty studies met the inclusion criteria. Results revealed EMR and EHR usability problems to include violations of natural dialog, control consistency, effective use of language, effective information presentation, and customization principles as well as a lack of error prevention, minimization of cognitive load, and feedback. Studies focusing on EMR system safety made no objective assessments and applied only inductive reasoning methods for hazard recognition. On the basis of the identified usability problems and structure of safety analysis techniques, we provide EMR design guidelines and a design concept focused on the diagnosis process and documentation. The design guidelines and new interface concept can be used for prototyping and testing enhanced EMRs. © 2015, Human Factors and Ergonomics Society.

    This paper reported on a field study that provided supportive ideas for environmental standards and design guidelines for office environments which could satisfy indoor environmental quality (IEQ) requirements. IEQ is an important variable affecting occupant health, productivity as well as organization success. As such, occupant comfort and satisfaction must be ensured for each component of IEQ, notably thermal quality, air quality, lighting quality, and noise. In partnership with the General Services Administration, the Center for Building Performance and Diagnostics research team at Carnegie Mellon conducted a post-occupancy evaluation field study of 20 commercial office buildings throughout the United States. The objective and subjective data of IEQ obtained from the study were used for correlational analysis. The study results provide evidences to modify office environmental design guideline to improve physiological and environmental benefits. 5 refs., 1 tab., 10 figs.

    Self-directed learning denotes that the individual is in command of what should be learned and why it is important. In this study, guidelines for the design of Web 2.0 systems for supporting diabetic adolescents' every day learning needs are examined in light of theories about information behaviour and social learning. A Web 2.0 system was developed to support a community of practice and social learning structures were created to support building of relations between members on several levels in the community. The features of the system included access to participation in the culture of diabetes management practice, entry to information about the community and about what needs to be learned to be a full practitioner or respected member in the community, and free sharing of information, narratives and experience-based knowledge. After integration with the key elements derived from theories of information behaviour, a preliminary design guideline document was formulated.

    1993-01-01

    This document provides guidelines for the design and evaluation of underground high-level waste storage tanks due to seismic loads. Attempts were made to reflect the knowledge acquired in the last two decades in the areas of defining the ground motion and calculating hydrodynamic loads and dynamic soil pressures for underground tank structures. The application of the analysis approach is illustrated with an example. The guidelines are developed for specific design of underground storage tanks, namely double-shell structures. However, the methodology discussed is applicable for other types of tank structures as well. The application of these and of suitably adjusted versions of these concepts to other structural types will be addressed in a future version of this document.

    Carpet weaving is a high risk occupation for developing musculoskeletal disorders (MSDs). The objectives of the present study, which was carried out in the Iranian hand-woven carpet industry, were determination of the prevalence of MSD symptoms, identification of major factors associated with MSD symptoms and development of guidelines for workstation design. 1,439 randomly selected weavers participated in this study. A questionnaire was used to collect data on MSD symptoms. The results revealed that the prevalence rates for symptoms in different body regions were high as compared to the general Iranian population (for neck, back and large joints, p loom type, working posture, daily working time and seat type. Based on the results, some general guidelines for designing weaving workstations were developed. A prototype test showed that the new workstation was acceptable for subject tests and that it improved working posture.

    2011-12-01

    Full Text Available The current work describes design guidelines for the development of Virtual Reality (VR and Augmented Reality (AR platforms to train technicians on maintenance and assembly tasks of industrial machineries. The main skill involved in this kind of tasks is the procedural skill. Based on past literature and studies conducted within the SKILLS project, several main design guidelines were formulated. First, observational learning integrated properly within the training protocol increases training efficiency. Second, training protocols combining physical and cognitive fidelity enhances procedural skills acquisition. Third, guidance aids should be provided in a proper and controlled way. And last, enriched information about the task helps trainees to develop a useful mental model of the task. These recommendations were implemented in both VR and AR training platforms.

    2000-01-01

    To describe a Web-based guideline tutorial system and evaluate its features. A Web-based tutorial system called SAGE (Self-study Acceleration with Graphic Evidence) was constructed to teach knowledge important for care after myocardial infarction. SAGE features a pretest, followed by an overview that coordinates studying resources for a set of learning objectives. Resources include pretest answers, guideline passages, and graphical presentations of clinical trial results. Data on the use of SAGE was obtained from 79 residents participating in a larger trial. Linear regression was used to correlate the amount learned with resource-use, and resource-use with user characteristics. On average, users accessed less than half of the guideline passages and very little of the graphic evidence. Greater use of guideline passages was correlated with greater immediate learning, but use of graphic evidence was not. Further research is needed to motivate more thorough self-study and to integrate clinical trial evidence with guideline-based education.

  11. Evaluating the impact and use of Transparent Reporting of Evaluations with Non-randomised Designs (TREND) reporting guidelines

    Science.gov (United States)

    Fuller, Thomas; Pearson, Mark; Peters, Jaime L; Anderson, Rob

    2012-01-01

    Introduction Accurate and full reporting of evaluation of interventions in health research is needed for evidence synthesis and informed decision-making. Evidence suggests that biases and incomplete reporting affect the assessment of study validity and the ability to include this data in secondary research. The Transparent Reporting of Evaluations with Non-randomised Designs (TREND) reporting guideline was developed to improve the transparency and accuracy of the reporting of behavioural and public health evaluations with non-randomised designs. Evaluations of reporting guidelines have shown that they can be effective in improving reporting completeness. Although TREND occupies a niche within reporting guidelines, and despite it being 8 years since publication, no study yet has assessed its impact on reporting completeness or investigated what factors affect its use by authors and journal editors. This protocol describes two studies that aim to redress this. Methods and analysis Study 1 will use an observational design to examine the uptake and use of TREND by authors, and by journals in their instructions to authors. A comparison of reporting completeness and study quality of papers that do and do not use TREND to inform reporting will be made. Study 2 will use a cross-sectional survey to investigate what factors inhibit or facilitate authors’ and journal editors’ use of TREND. Semistructured interviews will also be conducted with a subset of authors and editors to explore findings from study 1 and the surveys in greater depth. Ethics and dissemination These studies will generate evidence of how implementation and dissemination of the TREND guideline has affected reporting completeness in studies with experimental, non-randomised designs within behavioural and public health research. The project has received ethics approval from the Research Ethics Committee of the Peninsula College of Medicine and Dentistry, Universities of Exeter and Plymouth. PMID

  12. An Overview of a Decade of Journal Publications about Culture and Human-Computer Interaction (HCI)

    Science.gov (United States)

    Clemmensen, Torkil; Roese, Kerstin

    In this paper, we analyze the concept of human-computer interaction in cultural and national contexts. Building and extending upon the framework for understanding research in usability and culture by Honold [3], we give an overview of publications in culture and HCI between 1998 and 2008, with a narrow focus on high-level journal publications only. The purpose is to review current practice in how cultural HCI issues are studied, and to analyse problems with the measures and interpretation of this studies. We find that Hofstede's cultural dimensions has been the dominating model of culture, participants have been picked because they could speak English, and most studies have been large scale quantitative studies. In order to balance this situation, we recommend that more researchers and practitioners do qualitative, empirical work studies.

    2011-01-01

    Full Text Available This paper presents results from an empirical study conducted with a subliminal teaching technique aimed at enhancing learner's performance in Intelligent Systems through the use of physiological sensors. This technique uses carefully designed subliminal cues (positive and miscues (negative and projects them under the learner's perceptual visual threshold. A positive cue, called answer cue, is a hint aiming to enhance the learner's inductive reasoning abilities and projected in a way to help them figure out the solution faster but more importantly better. A negative cue, called miscue, is also used and aims at obviously at the opposite (distract the learner or lead them to the wrong conclusion. The latest obtained results showed that only subliminal cues, not miscues, could significantly increase learner performance and intuition in a logic-based problem-solving task. Nonintrusive physiological sensors (EEG for recording brainwaves, blood volume pressure to compute heart rate and skin response to record skin conductivity were used to record affective and cerebral responses throughout the experiment. The descriptive analysis, combined with the physiological data, provides compelling evidence for the positive impact of answer cues on reasoning and intuitive decision making in a logic-based problem-solving paradigm.

  1. Integrating IS and HCI Using Activity Theory as a Philosophical and Theoretical Basis

    Directory of Open Access Journals (Sweden)

    Helen Hasan

    1999-05-01

    Full Text Available The fields of Information Systems (IS and Human Computer Interaction (HCI are both multidisciplinary in nature and each is searching for an identity as a legitimate discipline in its own right, with a firm theoretical basis. Activity Theory offers a set of concepts, structures and terms which are eminently suited to both fields. It has its origins in the cultural historical psychology of Russia, and avoids the dichotomies between thought and action, and between individuals and society, that are prevalent in western thinking. This paper describes the basic principles of Activity Theory as they apply to IS and HCI, with particular emphasis on those systems which provide knowledge about the progress of their organisation to senior managers. Activity Theory principles will be used in a longitudinal case study to analyse an extensive project which attempted, with limited success, to produce management support systems in an organisation. The Activity Theory analysis indicates that an integrated IS and HCI approach would have improved the outcomes of this project.

    1983-01-01

    This document is a set of guidelines to aid a programmer in making the various decisions necessary for a clear user-programmer dialogue. Its goal is to promote an effective and efficient transfer of information between programmer and user. These guidelines are divided into four sections: (1) Format, (2) Sequence, (3) Audience, and (4) Aim. Format, in terms of this study, means the spatial and structural presentation of information. Sequence deals with the procedural aspects of multiple panel displays. This section looks at the issues of timelines of presentation, modularization of information, and patterns of user behavior. Audience looks at the relationship among programmer, user, and message. It covers the issues of analyzing the audience's knowledge, attitudes, and needs, anticipating the audience's inferences, and identifying textual ambiguities. The programmer's aim or intention shows up in everything from tone to format. Aim considers the programmer's purpose.

  5. Methodology of factorial design deriving guidelines for simulation of growth curve and production of sugars by Spirulina (Arthrospira) maxima

    Institute of Scientific and Technical Information of China (English)

    2001-01-01

    It is practical, economic and sometimes essential to derive rules or conclusions by performing lesser runs of experiments. In this part, a methodology based on 2f factorial design was brought up to derive guidelines to simulate growth curve and production of sugars by Spirulina (Arthrospira) maxima. The growth curve or accumulation process of sugars was idealized by sets of straight lines limited by phase transfers of growth or accumulation of sugars. Normal analyses of the critical values of the transfers were used to derive their linear relationships with the initial conditions of the experimental factors. These linear functions were called guidelines and were used to simulate the growth curve or accumulation of sugars. Generalization of the guideline technique was determined by the kinetic limitation of nutrient nitrogen or sulfur that was dependent upon their stoichiometric deficiency directly derived from their initial values in the medium. This method uses the initial conditions of culture and does not need measurements of concentrations of nitrate, sulfate and pigments during cultivation. It is a practical and useful alternative way to trace and predict approximately the growth curve and production of sugars by S. maxima.

  6. Design, Assembly and Preloading of Ball Bearings for Space Applications- Lessons Learned and Guidelines for Future Success

    Videra, E.; Lebreton, C.; Lewis, S. D.; Gaillard, L.

    2013-09-01

    The use of ball bearings in the space industry is commonplace, with a broad range of applications from the most precise pointing mechanisms to extreme long -life and performance-demanding reaction wheels and simpler single-shot devices where precision, performance and life may be less difficult to achieve. Though most application developments are ultimately successful, the lessons learned from the incorrect implementation of ball bearings are, usually for understandable commercial reasons, not widely distributed - but often extremely valuable for industry.The organizations contributing to this paper have an unprecedentedly clear view of numerous spacecraft applications, both successful and otherwise, together with many years of experience in design, handling, lubricating, preloading and testing ball bearings for space applications.In order to help the space community to avoid design or handling errors in future, ESA has mandated bearing manufacturer ADR, and the European Space Tribology Laboratory (ESTL) to create a useful guideline which summarises both best practice and a distillation of the lessons learned from many programs.This paper presents a selection of the more valuable and generally applicable lessons learned by these organizations in the last 30-40 years together with an overview of the recently published guideline document itself [1] which embodies this experience and contains recommendations concerning ball bearing selection, design and conceptual rules and recommendations for assembly, preloading and verification testing.The novelty of this paper comes from the broad range of experiences and applications, both good and bad that the organisations concerned have observed and the publication (for the first time) of guidelines for use by the space mechanisms community in Europe.

    2010-07-01

    In recent years, due to population growth, the numbers of enrolled students in Mansoura University, Egypt, has significantly increased, leading to a lack of library space. As a solution to this issue, the aim of this paper is to present the design procedures for building a portable library. The process consists of conducting a feasibility study, then identifying the most relevant parameters and using a software to create an energy efficient structure. A case study was conducted in Mansoura University on a portable library measuring 6.60mx9.90mx4.20m; simulations were carried out with the Ecotect simulation software. Results showed that the proposed methodology was successful in designing a portable library and that it allowed a reduction in energy consumption of 40% compared to the baseline case. This paper provided design guidelines for the construction of portable libraries through the use of transient building performance.

    2013-01-01

    We present design guidelines for using Adapted Primary Literature (APL) as part of current interdisciplinary topics to introductory physics students. APL is a text genre that allows students to comprehend a scientific article, while maintaining the core features of the communication among scientists, thus representing an authentic scientific discourse. We describe the adaptation of a research paper by Nobel Laureate Paul Flory on phase equilibrium in polymer-solvent mixtures that was presented to high school students in a project-based unit on soft matter. The adaptation followed two design strategies: a) Making explicit the interplay between the theory and experiment. b) Re-structuring the text to map the theory onto the students' prior knowledge. Specifically, we map the theory of polymer-solvent systems onto a model for binary mixtures of small molecules of equal size that was already studied in class.

    2008-12-01

    Full Text Available We present concurrent theoretical work from HCI and Education that reveals a convergence of trends focused on the importance of three themes: embodiment, multimodality, and composition. We argue that there is great potential for truly transformative work that aligns HCI and Education research, and posit that there is an important opportunity to advance this effort through the full integration of the three themes into a theoretical and technological framework for learning. We present our own work in this regard, introducing the Situated Multimedia Arts Learning Lab (SMALLab. SMALLab is a mixed-reality environment where students collaborate and interact with sonic and visual media through full-body, 3D movements in an open physical space. SMALLab emphasizes human-to-human interaction within a multimodal, computational context. We present a recent case study that documents the development of a new SMALLab learning scenario, a collaborative student participation framework, a student-centered curriculum, and a three-day teaching experiment for seventy-two earth science students. Participating students demonstrated significant learning gains as a result of the treatment. We conclude that our theoretical and technological framework can be broadly applied in the realization of mixed reality, student-centered learning environments.

    These proceedings contain the papers presented at the Eighth International Conference on the Physics of Highly Charged Ions (HCI-96) which was held on September 23-26, 1996 in Omiya, Saitama, Japan, hosted by the Institute of Physical and Chemical Research (RIKEN). The first conference of this series was held in Stockholm, Sweden in 1982. The subject was the "Production and Physics of Highly Charged Ions". The conference has since been held every other year; in Oxford, UK (1984), Groningen, the Netherlands (1986), Grenoble, France (1988), Giessen, Germany (1990), Manhattan, Kansas, USA (1992) and Vienna, Austria (1994). When the first conference of this series was held, various highly charged ions were available from many heavy ion accelerators, which had been constructed since the 1960's, and ion sources such as EBIS and ECRIS, which were then new facilities. Subsequently, many other experimental techniques have been developed to study or to control highly charged ions, such as ion traps, EBIT's, storage rings, high-brilliance synchrotron radiation, and so forth. Now the properties of highly charged ions themselves and their interactions with various kinds of materials can be studied systematically using ions of any element at various collision energies. These studies will result in a deeper insight into their nature as well as giving us important basic data for use in the fields closely related to atomic physics. About 190 scientists from 18 countries registered at the HCI-96. The number of invited talks was 21 and that of contrib- uted papers 215. In these proceedings, 20 papers of invited talks and 116 papers on contributions are included. They are classified into categories of "Structure and Spectroscopy of Highly Charged Ions and Fundamental Aspects", "Highly Charged Ions in Plasmas and Strong Fields", "Interactions of Highly Charged Ions with Atoms and Ions", "Dynamic Processes Related to Molecules and Clusters", "Interactions of Highly Charged Ions with

    Successful research outcomes require selection and implementation of the appropriate research design. A realistic sampling plan appropriate for the design is essential. Qualitative or quantitative methodology may be utilized, depending on the research question and goals. Quantitative research may be experimental where there is an intervention, or nonexperimental, if no intervention is included in the design. Causation can only be established with experimental research. Popular types of nonexperimental research include descriptive and survey research. Research findings may be disseminated via presentations, posters, and publications, such as abstracts and manuscripts.

  5. Design for interaction between humans and intelligent systems during real-time fault management

    1992-01-01

    Initial results are reported to provide guidance and assistance for designers of intelligent systems and their human interfaces. The objective is to achieve more effective human-computer interaction (HCI) for real time fault management support systems. Studies of the development of intelligent fault management systems within NASA have resulted in a new perspective of the user. If the user is viewed as one of the subsystems in a heterogeneous, distributed system, system design becomes the design of a flexible architecture for accomplishing system tasks with both human and computer agents. HCI requirements and design should be distinguished from user interface (displays and controls) requirements and design. Effective HCI design for multi-agent systems requires explicit identification of activities and information that support coordination and communication between agents. The effects are characterized of HCI design on overall system design and approaches are identified to addressing HCI requirements in system design. The results include definition of (1) guidance based on information level requirements analysis of HCI, (2) high level requirements for a design methodology that integrates the HCI perspective into system design, and (3) requirements for embedding HCI design tools into intelligent system development environments.

    In vitro experiments need to be well designed and correctly analysed if they are to achieve their full potential to replace the use of animals in research. An "experiment" is a procedure for collecting scientific data in order to answer a hypothesis, or to provide material for generating new hypotheses, and differs from a survey because the scientist has control over the treatments that can be applied. Most experiments can be classified into one of a few formal designs, the most common being completely randomised, and randomised block designs. These are quite common with in vitro experiments, which are often replicated in time. Some experiments involve a single independent (treatment) variable, while other "factorial" designs simultaneously vary two or more independent variables, such as drug treatment and cell line. Factorial designs often provide additional information at little extra cost. Experiments need to be carefully planned to avoid bias, be powerful yet simple, provide for a valid statistical analysis and, in some cases, have a wide range of applicability. Virtually all experiments need some sort of statistical analysis in order to take account of biological variation among the experimental subjects. Parametric methods using the t test or analysis of variance are usually more powerful than non-parametric methods, provided the underlying assumptions of normality of the residuals and equal variances are approximately valid. The statistical analyses of data from a completely randomised design, and from a randomised-block design are demonstrated in Appendices 1 and 2, and methods of determining sample size are discussed in Appendix 3. Appendix 4 gives a checklist for authors submitting papers to ATLA.

    Doc'CISMeF (DC) is a semantic search engine used to find resources in CISMeF-BP, a quality controlled health gateway, which gathers guidelines available on the internet in French. Visualization of Concepts in Medicine (VCM) is an iconic language that may ease information retrieval tasks. This study aimed to describe the creation and evaluation of an interface integrating VCM in DC in order to make this search engine much easier to use. Focus groups were organized to suggest ways to enhance information retrieval tasks using VCM in DC. A VCM interface was created and improved using the ergonomic evaluation approach. 20 physicians were recruited to compare the VCM interface with the non-VCM one. Each evaluator answered two different clinical scenarios in each interface. The ability and time taken to select a relevant resource were recorded and compared. A usability analysis was performed using the System Usability Scale (SUS). The VCM interface contains a filter based on icons, and icons describing each resource according to focus group recommendations. Some ergonomic issues were resolved before evaluation. Use of VCM significantly increased the success of information retrieval tasks (OR=11; 95% CI 1.4 to 507). Nonetheless, it took significantly more time to find a relevant resource with VCM interface (101 vs 65 s; p=0.02). SUS revealed 'good' usability with an average score of 74/100. VCM was successfully implemented in DC as an option. It increased the success rate of information retrieval tasks, despite requiring slightly more time, and was well accepted by end-users.

    During the design of Human-Computer Interaction (HCI) systems, the creation of visual artefacts forms an important part of design. On one hand producing a visual artefact has a number of advantages: it helps designers to externalise their thought and acts as a common language between different stakeholders. On the other hand, if an inappropriate visualisation method is employed it could hinder the design process. To support the design of HCI systems, this paper reviews the categorisation of visualisation methods used in HCI. A keyword search is conducted to identify a) current HCI design methods, b) approaches of selecting these methods. The resulting design methods are filtered to create a list of just visualisation methods. These are then categorised using the approaches identified in (b). As a result 23 HCI visualisation methods are identified and categorised in 5 selection approaches (The Recipient, Primary Purpose, Visual Archetype, Interaction Type, and The Design Process).

  11. Design guidelines for efficient plasmonic solar cells exploiting the trade-off between scattering and metallic absorption

    CERN Document Server

    Li, Xiaofeng; Giannini, Vincenzo; Ekins-Daukes, Ned J; Maier, Stefan A

    2014-01-01

    We report on the role of plasmonic resonances in determining the delicate balance between scattering and absorption of light in nanometric particle arrays applied to the front surface of solar cells. Strong parasitic absorption is shown to be dependent upon the excitation of localized surface plasmon resonances and prohibits efficient scattering into the underlying semiconductor. Via detailed analytical and numerical investigations we obtain the dependence of scattering and absorption in nanoparticles upon their complex refractive index. These results provide an insight into the optimum material properties required to minimize parasitic optical absorption, while maintaining high scattering cross-section efficiency, thus providing a general design guideline for efficient light trapping with scattering nanoparticles. The work is extended to include comprehensive optoelectronic simulations of plasmonic solar cells in which the scattering metals are made from either Au, Ag or Al. We show that Al particles provide...

  19. Changing energy efficient houses into net zero energy houses : guidelines for a design exercise

    Energy Technology Data Exchange (ETDEWEB)

    Proskiw, G. [Proskiw Engineering Ltd., Winnipeg, MB (Canada); Hockman, J. [J.L. Hockman Consulting Inc., Winnipeg, MB (Canada)

    2006-03-31

    A net zero energy house (NZEH) generates surplus energy during certain portions of the year which can then be sold back to a utility through the existing power grid or pipeline. The surplus equals or exceeds the power which has to be purchased from the utility during the remaining parts of the year, which means that the house uses the power grid as a permanently connected energy storage system. This paper provided details of a conceptual design exercise to upgrade the design of an existing energy efficient Canadian house from its current performance level to that of a NZEH. The design objectives included the caveat that the occupants should maintain the standard of living enjoyed in the house before NZEH modifications. The simulation program HOT2000 was used to predict the energy performance of the house. Default values were selected for thermostat settings; appliance energy usage, domestic hot water (DHW) consumption; and metabolic gains. Both wood heating and on-site hydro generation were excluded from the design exercise because neither were judged as realistic options for the vast majority of Canadians. An assumption of no external shading from adjacent structures was selected to produce optimum solar advantage. It was decided that photovoltaics (PV) would provide the major source of on-site power generation despite their high initial cost. The monitoring and energy analysis program indicated that the house would exceed its energy target by 53 per cent. However, 78 per cent of the over-consumption was due to limitations of the computer software initially used to design the house in 1992. Mechanical systems were judged as too complex, too expensive and too unreliable. The mechanical ventilation system maintained good air quality, but was overly-complex. Overheating was a problem despite the use of exterior solar shade screens. Better design tools were needed to assess the probability of overheating. No major problems were encountered with the building envelope

  20. Design guidelines for passive instability suppression - Task-11 report[Wind turbines

    Energy Technology Data Exchange (ETDEWEB)

    Hansen, M.H.; Buhl, T.

    2006-12-15

    In these guidelines for passive instability suppression, eight relevant topics within aeroelastic stability of turbines are considered for the parameter variations: 1. Effect of airfoil aerodynamics: The airfoil aerodynamics given by the profile coefficients for aerodynamic lift, drag, and moment are shown to have a direct effect on aerodynamic damping of blade vibrations. A redesign of the airfoils can improve the power performance of the rotor without loss of aerodynamic damping. 2. Effect of flap/edgewise frequency coincidence: The natural frequencies of the first flapwise and first edgewise blade bending modes become closer as the blades become more slender. This 1-1 resonance may lead to a coupling flap- and edgewise blade vibrations which increases the edgewise blade mode damping. 3. Effect of flap/edgewise whirling coupling: The aerodynamic damping of blade vibrations close to the rotor plane are generally lower than the aerodynamic damping of vibrations out of the rotor plane. A structural coupling between the flapwise and edgewise whirling modes can increase the overall aerodynamic damping by adding more out of plane blade motion to the edgewise whirling modes. 4. Effect of torsional blade stiffness: A low torsional blade stiffness may lead to flutter where the first torsional blade mode couples to a flapwise bending mode in a flutter instability through the aerodynamic forces. 5. Can whirl flutter happen on a wind turbine? Whirl flutter is an aeroelastic instability similar to blade flutter. Whirl flutter can occur on turbines with very low natural frequencies of the tilt and yaw modes (about 5 % of their original values). 6. Edgewise/torsion coupling for large flapwise deflections: The large flapwise deflection of modern slender blades lead to a geometric coupling of edgewise bending and torsion. The aeroelastic damping of the blade modes are affected by a flapwise prebend of the blade. 7. Effect of yaw error on damping from wake: The wake behind the

  3. Case Study of Online Banking in India: User Behaviors and Design Guidelines

    Science.gov (United States)

    Iyengar, Jhumkee; Belvalkar, Manisha

    This paper documents online banking trends, behaviors and expectations of Indian consumers and banks. It is based on excerpts of a large industry case study of users from 4 leading banks. While banks view online banking essentially as a technology solution, it is a relatively new area for Indian consumers and not yet self-supporting. Being a savings based culture still, Indian consumers are cautious about their financial assets. They are also relatively recent entrants to internet based services. Design of these systems must therefore be based on an understanding of these users' outlook and priorities through task centric, security assured and service oriented solutions minus the technological challenges. Design lessons suggest viewing online banking not just as a convenience alone anymore but beyond it, to provide service, simplicity and security. This will create satisfied online banking customers and therefore profitability for the bank.

  5. Design guidelines for advanced LSI microcircuit packaging using thick film multilayer technology

    Science.gov (United States)

    Peckinpaugh, C. J.

    1974-01-01

    Ceramic multilayer circuitry results from the sequential build-up of two or more layers of pre-determined conductive interconnections separated by dielectric layers and fired at an elevated temperature to form a solidly fused structure. The resultant ceramic interconnect matrix is used as a base to mount active and passive devices and provide the necessary electrical interconnection to accomplish the desired electrical circuit. Many methods are known for developing multilevel conductor mechanisms such as multilayer printed circuits, welded wire matrices, flexible copper tape conductors, and thin and thick-film ceramic multilayers. Each method can be considered as a specialized field with each possessing its own particular set of benefits and problems. This design guide restricts itself to the art of design, fabrication and assembly of ceramic multilayer circuitry and the reliability of the end product.

    Gibon, Yves; Rolin, Dominique

    2012-01-01

    Experiments involve the deliberate variation of one or more factors in order to provoke responses, the identification of which then provides the first step towards functional knowledge. Because environmental, biological, and/or technical noise is unavoidable, biological experiments usually need to be designed. Thus, once the major sources of experimental noise have been identified, individual samples can be grouped, randomised, and/or pooled. Like other 'omics approaches, metabolomics is characterised by the numbers of analytes largely exceeding sample number. While this unprecedented singularity in biology dramatically increases false discovery, experimental error can nevertheless be decreased in plant metabolomics experiments. For this, each step from plant cultivation to data acquisition needs to be evaluated in order to identify the major sources of error and then an appropriate design can be produced, as with any other experimental approach. The choice of technology, the time at which tissues are harvested, and the way metabolism is quenched also need to be taken into consideration, as they decide which metabolites can be studied. A further recommendation is to document data and metadata in a machine readable way. The latter should also describe every aspect of the experiment. This should provide valuable hints for future experimental design and ultimately give metabolomic data a second life. To facilitate the identification of critical steps, a list of items to be considered before embarking on time-consuming and costly metabolomic experiments is proposed.

    Full Text Available Sustainability assessment tools have been developed for building-scale sustainability since the 1990s. Several systems, such as BREEAM (Building Research Establishment Environmental Assessment Methodology, LEED (Leadership in Energy and Environmental Design and CASBEE (Comprehensive Assessment System for Built Environment Efficiency, are widely used and have been upgraded and adapted to large-scale development. BREEAM Communities, LEED Neighborhood Development and CASBEE for Urban Development have been implemented in the UK, the USA and Japan, respectively. As the notion of sustainable urban design has gained more significance, city governments have set their own guidelines for sustainable standards in urban design based on studies of sustainability assessment tools. This study focused on a comparative analysis of the material criteria embedded for sustainable urban design in BREEAM Communities, LEED-ND (Neighborhood Development and CASBEE-UD (Urban Development, and the urban design guidelines recently issued in multiple cities, including London, New York, Tokyo, and Seoul. The top master plans and the supplementary guidelines were analyzed to investigate the detailed material criteria. The study examined the differences in the material assessment criteria, evaluation parameters, and descriptions of the neighborhood sustainability assessment tools and the urban design guidelines. The material criteria was investigated and discussed to summarize the current features and weaknesses as balanced material assessments for sustainable urban development.

    2016-08-01

    Full Text Available This position paper presents observations from a flipped classroom experience of teaching an HCI bachelor course at the University of Trento (Italy in Fall 2015. Students were provided with conventional lectures, digital learning materials in Moodle, and a collaborative prototyping platform for supporting project work over the 2-months course duration. Overall, students highly appreciated the flexibility of having access to a combination of digital and conventional teaching resources. However, we observed a rather slow adoption of the remote collaboration features offered by the prototyping platform during the project work. This shows students’ initial reluctance and lack of familiarity with using asynchronous communication-collaboration tools for better managing their group work and learning in blended education programs.

  10. SafeLand guidelines for landslide monitoring and early warning systems in Europe - Design and required technology

    Bazin, S.

    2012-04-01

    Landslide monitoring means the comparison of landslide characteristics like areal extent, speed of movement, surface topography and soil humidity from different periods in order to assess landslide activity. An ultimate "universal" methodology for this purpose does not exist; every technology has its own advantages and disadvantages. End-users should carefully consider each one to select the methodologies that represent the best compromise between pros and cons, and are best suited for their needs. Besides monitoring technology, there are many factors governing the choice of an Early Warning System (EWS). A people-centred EWS necessarily comprises five key elements: (1) knowledge of the risks; (2) identification, monitoring, analysis and forecasting of the hazards; (3) operational centre; (4) communication or dissemination of alerts and warnings; and (5) local capabilities to respond to the warnings received. The expression "end-to-end warning system" is also used to emphasize that EWSs need to span all steps from hazard detection through to community response. The aim of the present work is to provide guidelines for establishing the different components for landslide EWSs. One of the main deliverables of the EC-FP7 SafeLand project addresses the technical and practical issues related to monitoring and early warning for landslides, and identifies the best technologies available in the context of both hazard assessment and design of EWSs. This deliverable targets the end-users and aims to facilitate the decision process by providing guidelines. For the purpose of sharing the globally accumulated expertise, a screening study was done on 14 EWSs from 8 different countries.

    This volume contains the Proceedings of the 14th International Conference on the Physics of Highly Charged Ions (HCI2008), held at the University of Electro-Communications, Chofu, Tokyo, Japan from 1-5 September 2008. This series of conferences began in Stockholm, Sweden in 1982 and has since been held every other year; in Oxford, UK (1984), Groningen, the Netherlands (1986), Grenoble, France (1988), Giessen, Germany (1990), Manhattan, Kansas, USA (1992), Vienna, Austria (1994), Omiya, Japan (1996), Bensheim, Germany (1998), Berkeley, USA (2000), Caen, France (2002), Vilnius, Lithuania (2004) and Belfast, UK (2006). Highly charged ions (HCI), which are defined as highly ionized (i.e. positively charged atomic) ions here, mainly exist in hot plasmas such as the solar corona and fusion plasmas. It is true that its importance in plasma physics has driven researchers to the spectroscopic studies of HCIs, but the spectroscopy of few-electron ions is not only important for plasmas but also interesting for fundamental atomic physics. Electrons moving fast near a heavy nucleus give a suitable system to test the fundamental atomic theory involving relativistic and quantum electro-dynamic effects in a strong field. Also, the huge potential energy of a HCI induces drastic reaction in the interaction with matter. This unique property of HCIs, coupled with the recent development of efficient ion sources, is opening the possibility to utilize them in new technologies in the field such as nano-fabrication, surface analysis, medical physics, and so on. Hence, this conference is recognized as a valuable gathering place for established practitioners and also for newcomers; we exchange information, we are introduced to the subject itself, and to unexpected interfaces with other fields. On 31 August, the day before the opening of HCI2008, we welcomed the delegates at the university's restaurant—and we were greeted with an unusually heavy summer shower! The conference then opened on

    1993-03-18

    This report develops and applies a methodology for estimating strong earthquake ground motion. The motivation was to develop a much needed tool for use in developing the seismic requirements for structural designs. An earthquake`s ground motion is a function of the earthquake`s magnitude, and the physical properties of the earth through which the seismic waves travel from the earthquake fault to the site of interest. The emphasis of this study is on ground motion estimation in Eastern North America (east of the Rocky Mountains), with particular emphasis on the Eastern United States and southeastern Canada. Eastern North America is a stable continental region, having sparse earthquake activity with rare occurrences of large earthquakes. While large earthquakes are of interest for assessing seismic hazard, little data exists from the region to empirically quantify their effects. Therefore, empirically based approaches that are used for other regions, such as Western North America, are not appropriate for Eastern North America. Moreover, recent advances in science and technology have now made it possible to combine theoretical and empirical methods to develop new procedures and models for estimating ground motion. The focus of the report is on the attributes of ground motion in Eastern North America that are of interest for the design of facilities such as nuclear power plants. Specifically considered are magnitudes M from 5 to 8, distances from 0 to 500 km, and frequencies from 1 to 35 Hz.

A numerical model of the evaporator is combined with cycle calculations, for estimating the impact of heat transfer area and pressure drop on the coefficient of performance and costs. Common trends are obtained as optimal configurations for the four considered fluids...... minimization of area and pressure drop is found by assessing the relative impact on costs of the heat exchanger area and pressure losses of both working fluid and heat source. The result shows that it is not always convenient to minimize the heat transfer area, since the mixture pressure drop negatively......The present work derives design recommendations for plate heat exchangers used for evaporation of zeotropic mixtures in heat pumps. A parametric study is conducted on the geometry of the heat exchanger, and the analysis is carried out for four working fluids, based on a case study of heat pump...

    2014-01-01

    Visual analysis of graphic displays of data is a cornerstone of studies using a single case experimental design (SCED). Data are graphed for each participant during a study with trend, level, and stability of data assessed within and between conditions. Reliable interpretations of effects of an intervention are dependent on researchers' understanding and use of systematic procedures. The purpose of this paper is to provide readers with a rationale for visual analysis of data when using a SCED, a step-by-step guide for conducting a visual analysis of graphed data, as well as to highlight considerations for persons interested in using visual analysis to evaluate an intervention, especially the importance of collecting reliability data for dependent measures and fidelity of implementation of study procedures.

  15. Design Guidelines for Ferrite Absorbers Submitted to RF-induced Heating

    CERN Document Server

    Bertarelli, A

    2013-01-01

    The use of ferrite absorbers is one of the most effective means of damping potentially harmful high order RF modes, which may lead to beam instabilities and excessive power losses in accelerator devices. However, the power deposited on ferrite absorbers themselves maylead to ferrite exceeding its Curie temperature, losing its damping properties. An evaluation of the ferrite capability to dissipate deposited heat is hence of paramount importance for the safe design of particle accelerator devices. In this paper, figures of merit are proposed to assess the maximum specific power allowed on a generic ferrite tile, before it reaches its Curie temperature. Due to its inherent brittleness, sufficient contact pressure between ferrite and its housing, allowing heat transmission by conduction, can hardly be applied. A semi-analytical study is thus performed, assuming that ferrite is evacuating heat solely through radiation. The described method is then exemplified in the case of the BPM-embedded tertiary collimator (T...

    Full Text Available The present work is a proposed optimization model of grid sub-stiffened panels for aerospace applications, having a better knowledge about the stability analysis of conventional grid sub-stiffened panels against loading and different mode of failure occurring lead us thinking about the topology optimization. In a first stage, we will analyse the stability performance of such structures against specific mechanical loading and conclude some techniques to introduce a topology optimization through PSO algorithm of some design variables. The aim is the better exploitation of the sub-stiffened panel along the plan so that the area less stressed due the charging will be extruded in mass for the enhancement of the concept of looking for better performance with a structure already saved in weight.

    PETC developed a comprehensive program of coal-related, acid-rain research and development with a major activity area centering on flue gas cleanup and control of SO{sub 2} emissions. Particular emphasis was placed on the retrofit measures for older coal-fired power plants which predate the 1971 New Source Performance Standards. Candidate emission control technologies fall into three categories, depending upon their point of application along the fuel path (i.e., pre, during, or post combustion). The post-combustion, in-duct injection of a calcium-based chemical reagent seemed promising. Preliminary studies showed that reagent injection between the existing air heater and electrostatic precipitator (ESP) could remove between 50-60% of the SO{sub 2} and produce an environmentally safe, dry, solid waste that is easily disposed. Although SO{sub 2} removal efficiencies were less, the estimated capital costs for duct injection technology were low making the economics of duct injection systems seem favorable when compared to conventional wet slurry scrubbers under certain circumstances. With the promulgation of the Clean Air Act Amendments of 1990 came more incentive for the development of low capital cost flue gas desulfurization (FGD) processes. A number of technical problems had to be resolved, however, before duct injection technology could be brought to a state of commercial readiness. The Duct Injection Technology Development Program was launched as a comprehensive, four-year research effort undertaken by PETC to develop this new technology. Completed in 1992, this Duct Injection Design Handbook and the three-dimensional predictive mathematical model constitute two primary end products from this development program. The aim of this design handbook and the accompanying math model is to provide utility personnel with sufficient information to evaluate duct injection technology against competing SO{sub 2} emissions reduction strategies for an existing plant.

  19. The principles and guidelines for designing long-term agronomic experiments

    2009-01-01

    Many of the important questions facing farming systems in the world today require long-term studies to provide meaningful information and answers. A long-term agronomic experiment (LTAE) should (1) have long-term objectives; (2) study important soil processes or ecological processes; and (3) be related to the productivity and sustainability of systems. A well established LTAE can provide both insights into how the system operates and foresight into where the system goes. The prerequisites for setting up a LTAE are the secured land, continuous funding and dedicated scientists. A number of principles must be considered carefully when establishing a LTAE, (1) the site must be representative of large areas; (2) the treatments should be simple, but focusing on the big questions; (3) the plots should be large enough to allow subsequent modification of the experiment if this becomes necessary; (4) crop rotations should minimise, wherever possible, the risk of build-up of pests and diseases, and rotational phase should be considered in a rotational experiment; (5) a clearly defined experimental protocol should be developed to ensure data collected is scientifically valid and statistically analysable, but with flexibility to allow essential changes; (6) soil samples, possibly plant samples, should be achieved to provide better answer to the original questions when new, perhaps more accurate analytical techniques are developed, or answer new research questions that were not considered in the original design. The MASTER experiment in Australia was used as a case study to demonstrate how these principles are implemented in practice.

    Full Text Available Ramadan fasting is specific intermittent fasting comprising significant changes in routine lifestyle pattern and may affect body homeostasis and metabolism. In spite of several studies conducted on the effects of Ramadan fasting on various aspects of health and disease, because of heterogeneity in methodology and procedures (sometimes inevitable, a comprehensive concluding for reliable results as in most conditions is impossible. Based on basic studies and those have been conducted in this field, this paper suggests a checklist contains, as far as possible, important factors to be considered in designing, interpreting and comparing the results of Ramadan fasting studies. Accordingly, circadian rhythm, season/latitude sensitivity, serum osmolarity and, lifestyle changes (including dietary intakes, physical activity, sleep quality and duration, smoking and, etc. may be of great importance. Also, a close definition of the number of fasting days and it consecutively or alternatively must be presented with reference to sex. Appropriate time points for blood/urine sampling would be varied case by case.

  1. Mismatch oligonucleotides in human and yeast: guidelines for probe design on tiling microarrays

    2008-12-01

    Full Text Available Abstract Background Mismatched oligonucleotides are widely used on microarrays to differentiate specific from nonspecific hybridization. While many experiments rely on such oligos, the hybridization behavior of various degrees of mismatch (MM structure has not been extensively studied. Here, we present the results of two large-scale microarray experiments on S. cerevisiae and H. sapiens genomic DNA, to explore MM oligonucleotide behavior with real sample mixtures under tiling-array conditions. Results We examined all possible nucleotide substitutions at the central position of 36-nucleotide probes, and found that nonspecific binding by MM oligos depends upon the individual nucleotide substitutions they incorporate: C→A, C→G and T→A (yielding purine-purine mispairs are most disruptive, whereas A→X were least disruptive. We also quantify a marked GC skew effect: substitutions raising probe GC content exhibit higher intensity (and vice versa. This skew is small in highly-expressed regions (± 0.5% of total intensity range and large (± 2% or more elsewhere. Multiple mismatches per oligo are largely additive in effect: each MM added in a distributed fashion causes an additional 21% intensity drop relative to PM, three-fold more disruptive than adding adjacent mispairs (7% drop per MM. Conclusion We investigate several parameters for oligonucleotide design, including the effects of each central nucleotide substitution on array signal intensity and of multiple MM per oligo. To avoid GC skew, individual substitutions should not alter probe GC content. RNA sample mixture complexity may increase the amount of nonspecific hybridization, magnify GC skew and boost the intensity of MM oligos at all levels.

    Full Text Available Abstract Background Biomechanical energy harvesting from human motion presents a promising clean alternative to electrical power supplied by batteries for portable electronic devices and for computerized and motorized prosthetics. We present the theory of energy harvesting from the human body and describe the amount of energy that can be harvested from body heat and from motions of various parts of the body during walking, such as heel strike; ankle, knee, hip, shoulder, and elbow joint motion; and center of mass vertical motion. Methods We evaluated major motions performed during walking and identified the amount of work the body expends and the portion of recoverable energy. During walking, there are phases of the motion at the joints where muscles act as brakes and energy is lost to the surroundings. During those phases of motion, the required braking force or torque can be replaced by an electrical generator, allowing energy to be harvested at the cost of only minimal additional effort. The amount of energy that can be harvested was estimated experimentally and from literature data. Recommendations for future directions are made on the basis of our results in combination with a review of state-of-the-art biomechanical energy harvesting devices and energy conversion methods. Results For a device that uses center of mass motion, the maximum amount of energy that can be harvested is approximately 1 W per kilogram of device weight. For a person weighing 80 kg and walking at approximately 4 km/h, the power generation from the heel strike is approximately 2 W. For a joint-mounted device based on generative braking, the joints generating the most power are the knees (34 W and the ankles (20 W. Conclusions Our theoretical calculations align well with current device performance data. Our results suggest that the most energy can be harvested from the lower limb joints, but to do so efficiently, an innovative and light-weight mechanical design is

    2016-03-01

    Reactive nitrogen species, such as nitric oxide (NO), exert their biological activity in large part through post-translational modification of cysteine residues, forming S-nitrosothiols. This chemical reaction proceeds via a process that we and our colleagues have termed protein S-nitrosylation. Under conditions of normal NO production, S-nitrosylation regulates the activity of many normal proteins. However, in degenerative conditions characterized by nitrosative stress, increased levels of NO lead to aberrant S-nitrosylation that contributes to the pathology of the disease. Thus, S-nitrosylation has been implicated in a wide range of cellular mechanisms, including mitochondrial function, proteostasis, transcriptional regulation, synaptic activity, and cell survival. In recent years, the research area of protein S-nitrosylation has become prominent due to improvements in the detection systems as well as the demonstration that protein S-nitrosylation plays a critical role in the pathogenesis of neurodegenerative and other neurological disorders. To further promote our understanding of how protein S-nitrosylation affects cellular systems, guidelines for the design and conduct of research on S-nitrosylated (or SNO-)proteins would be highly desirable, especially for those newly entering the field. In this review article, we provide a strategic overview of designing experimental approaches to study protein S-nitrosylation. We specifically focus on methods that can provide critical data to demonstrate that an S-nitrosylated protein plays a (patho-)physiologically-relevant role in a biological process. Hence, the implementation of the approaches described herein will contribute to further advancement of the study of S-nitrosylated proteins, not only in neuroscience but also in other research fields.

  12. Exploring the role of haptic feedback in enabling implicit HCI-based bookmarking.

    Science.gov (United States)

    Pan, Matthew K X J; McGrenere, Joanna; Croft, Elizabeth A; MacLean, Karon E

    2014-03-01

    We examine how haptic feedback could enable an implicit human-computer interaction, in the context of an audio stream listening use case where a device monitors a user's electrodermal activity for orienting responses to external interruptions. When such a response is detected, our previously developed system automatically places a bookmark in the audio stream for later resumption of listening. Here, we investigate two uses of haptic feedback to support this implicit interaction and mitigate effects of noisy (false-positive) bookmarking: (a) low-attention notification when a bookmark is placed, and (b) focused-attention display of bookmarks during resumptive navigation. Results show that haptic notification of bookmark placement, when paired with visual display of bookmark location, significant improves navigation time. Solely visual or haptic display of bookmarks elicited equivalent navigation time; however, only the inclusion of haptic display significantly increased accuracy. Participants preferred haptic notification over no notification at interruption time, and combined haptic and visual display of bookmarks to support navigation to their interrupted location at resumption time. Our contributions include an approach to handling noisy data in implicit HCI, an implementation of haptic notifications that signal implicit system behavior, and discussion of user mental models that may be active in this context.

  13. A Novel Camera Calibration Algorithm as Part of an HCI System: Experimental Procedure and Results

    2006-02-01

    Full Text Available Camera calibration is an initial step employed in many computer vision applications for the estimation of camera parameters. Along with images of an arbitrary scene, these parameters allow for inference of the scene's metric information. This is a primary reason for camera calibration's significance to computer vision. In this paper, we present a novel approach to solving the camera calibration problem. The method was developed as part of a Human Computer Interaction (HCI System for the NASA Virtual GloveBox (VGX Project. Our algorithm is based on the geometric properties of perspective projections and provides a closed form solution for the camera parameters. Its accuracy is evaluated in the context of the NASA VGX, and the results indicate that our algorithm achieves accuracy similar to other calibration methods which are characterized by greater complexity and computational cost. Because of its reliability and wide variety of potential applications, we are confident that our calibration algorithm will be of interest to many.

    2015-01-01

    Aims: In this work, we discuss a way to combine High Dispersion Spectroscopy and High Contrast Imaging (HDS+HCI). For a planet located at a resolvable angular distance from its host star, the starlight can be reduced up to several orders of magnitude using adaptive optics and/or coronography. In addition, the remaining starlight can be filtered out using high-dispersion spectroscopy, utilizing the significantly different (or Doppler shifted) high-dispersion spectra of the planet and star. In this way, HDS+HCI can in principle reach contrast limits of ~1e-5 x 1e-5, although in practice this will be limited by photon noise and/or sky-background. Methods: We present simulations of HDS+HCI observations with the E-ELT, both probing thermal emission from a planet at infrared wavelengths, and starlight reflected off a planet atmosphere at optical wavelengths. For the infrared simulations we use the baseline parameters of the E-ELT and METIS instrument, with the latter combining extreme adaptive optics with an R=100,...

  16. WWTP design in warm climates - guideline comparison and parameter adaptation for a full-scale activated sludge plant using mass balancing.

    Walder, C; Lindtner, S; Proesl, A; Klegraf, F; Weissenbacher, N

    2013-01-01

    The ATV-A-131 guideline and the design approach published in 'Wastewater Engineering, Treatment and Reuse (WE)' are widely used for the design of activated sludge plants. They are both based on simplified steady-state assumptions tailored to the boundary conditions of temperate climates. Using design guidelines beyond the designated temperature range may lead to inappropriate results. The objectives of this paper are (1) to summarise temperature relevant differences between ATV-A-131 and WE; (2) to show the related design components; and (3) to demonstrate a procedure for design parameter adaptation for a full-scale activated sludge plant located in a warm climate region. To gain steady-state data required for wastewater treatment plant (WWTP) design according to ATV-A-131 and WE, full-scale plant data were acquired for a period of 6 months as a basis for analyses and adaptation. Mass balances were calculated for the verification of the measurements and for analysing excess sludge production. The two approaches showed relevant temperature related differences. WE default application resulted in lower deviation in the mass balance results for excess sludge production. However, with the adaptation of the heterotrophic decay rates for both approaches and the inert organic and mineral solids fraction additionally for ATV-A-131, a good fit to the observed excess sludge production could be achieved.

    2015-01-22

    In order to improve human computer interaction (HCI) for people with special needs, this paper presents an alternative form of interaction, which uses the iPad's front camera and eye/head tracking technology. With this functional nature/capability operating in the background, the user can control already developed or new applications for the iPad by moving their eyes and/or head. There are many techniques, which are currently used to detect facial features, such as eyes or even the face itself. Open source bookstores exist for such purpose, such as OpenCV, which enable very reliable and accurate detection algorithms to be applied, such as Haar Cascade using very high-level programming. All processing is undertaken in real time, and it is therefore important to pay close attention to the use of limited resources (processing capacity) of devices, such as the iPad. The system was validated in tests involving 22 users of different ages and characteristics (people with dark and light-colored eyes and with/without glasses). These tests are performed to assess user/device interaction and to ascertain whether it works properly. The system obtained an accuracy of between 60% and 100% in the three test exercises taken into consideration. The results showed that the Haar Cascade had a significant effect by detecting faces in 100% of cases, unlike eyes and the pupil where interference (light and shade) evidenced less effectiveness. In addition to ascertaining the effectiveness of the system via these exercises, the demo application has also helped to show that user constraints need not affect the enjoyment and use of a particular type of technology. In short, the results obtained are encouraging and these systems may continue to be developed if extended and updated in the future.

    Full Text Available In order to improve human computer interaction (HCI for people with special needs, this paper presents an alternative form of interaction, which uses the iPad’s front camera and eye/head tracking technology. With this functional nature/capability operating in the background, the user can control already developed or new applications for the iPad by moving their eyes and/or head. There are many techniques, which are currently used to detect facial features, such as eyes or even the face itself. Open source bookstores exist for such purpose, such as OpenCV, which enable very reliable and accurate detection algorithms to be applied, such as Haar Cascade using very high-level programming. All processing is undertaken in real time, and it is therefore important to pay close attention to the use of limited resources (processing capacity of devices, such as the iPad. The system was validated in tests involving 22 users of different ages and characteristics (people with dark and light-colored eyes and with/without glasses. These tests are performed to assess user/device interaction and to ascertain whether it works properly. The system obtained an accuracy of between 60% and 100% in the three test exercises taken into consideration. The results showed that the Haar Cascade had a significant effect by detecting faces in 100% of cases, unlike eyes and the pupil where interference (light and shade evidenced less effectiveness. In addition to ascertaining the effectiveness of the system via these exercises, the demo application has also helped to show that user constraints need not affect the enjoyment and use of a particular type of technology. In short, the results obtained are encouraging and these systems may continue to be developed if extended and updated in the future.

    Full Text Available Presenting a context-aware service and information is a key aspect of ubiquitous computing, but development of such applications is quite complicated. Context-aware applications should be able to obtain raw data fromsensors, create highlevel context information, detect the user’s situation, and adapt the behavior of the application to the recognized situation . These complexities caused to reduce the impact of context -awareness in mobile computing while sensors of smartphones have made huge potential for developing context aware mobile applications. In this paper, we explain some guidelines to overcome the existing obstacles by separating the context -aware application layers and make a loosely coupled connection between them. These guidelines will bring easy and rapid development, reusability of the code and flexibility for developers. Finally, we provide a case study example in the Android platform to demonstrate how the guidelines can be used in a real application.

    A hardcopy or paper cognitive aid has been shown to improve performance during the management of simulated local anesthetic systemic toxicity (LAST) when given to the team leader. However, there remains room for improvement to ensure a system that can achieve perfect adherence to the published guidelines for LAST management. Recent research has shown that implementing a checklist via a designated reader may be of benefit. Accordingly, we sought to investigate the effect of an electronic decision support tool (DST) and designated "Reader" role on team performance during an in situ simulation of LAST. Participants were randomized to Reader + DST (n = 16, rDST) and Control (n = 15, memory alone). The rDST group received the assistance of a dedicated Reader on the response team who was equipped with an electronic DST. The primary outcome measure was adherence to guidelines. For overall and critical percent correct scores, the rDST group scored higher than Control (99.3% vs 72.2%, P Reader with an electronic DST improved adherence to guidelines in the management of an in situ simulation of LAST. Such tools are promising in the future of medicine, but further research is needed to ensure the best methods for implementing them in the clinical arena.

  6. Web Accessibility and Guidelines

    Science.gov (United States)

    Harper, Simon; Yesilada, Yeliz

    Access to, and movement around, complex online environments, of which the World Wide Web (Web) is the most popular example, has long been considered an important and major issue in the Web design and usability field. The commonly used slang phrase ‘surfing the Web’ implies rapid and free access, pointing to its importance among designers and users alike. It has also been long established that this potentially complex and difficult access is further complicated, and becomes neither rapid nor free, if the user is disabled. There are millions of people who have disabilities that affect their use of the Web. Web accessibility aims to help these people to perceive, understand, navigate, and interact with, as well as contribute to, the Web, and thereby the society in general. This accessibility is, in part, facilitated by the Web Content Accessibility Guidelines (WCAG) currently moving from version one to two. These guidelines are intended to encourage designers to make sure their sites conform to specifications, and in that conformance enable the assistive technologies of disabled users to better interact with the page content. In this way, it was hoped that accessibility could be supported. While this is in part true, guidelines do not solve all problems and the new WCAG version two guidelines are surrounded by controversy and intrigue. This chapter aims to establish the published literature related to Web accessibility and Web accessibility guidelines, and discuss limitations of the current guidelines and future directions.

    Low back pain (LBP) is one of the most prevalent and expensive health care problems in industrialised countries. LBP leads to high health care utility and productivity losses; leaving the individual, the employer, and society with substantial costs. To improve the care for LBP patients and reduce the high societal and financial burden of LBP, in 2010 the 'Multidisciplinary care guideline for nonspecific low back pain' was developed in the Netherlands. The current paper describes the design of a study aiming to evaluate the (cost-) effectiveness of a multifaceted strategy to implement this guideline. In a cluster-randomised controlled trial, the (cost-) effectiveness of a multifaceted implementation strategy will be compared to passive guideline dissemination. Using a stepped-wedge approach, participating general practitioners, physiotherapists, and occupational physicians are allocated into clusters and will attend a multidisciplinary continuing medical education training session. The timing these clusters receive the training is the unit of randomisation. LBP patients visiting the participating health care providers are invited to participate in the trial and will receive access to a multimedia intervention aimed at improving beliefs, cognitions, and self-management. The primary outcome measure of this study is patient back beliefs. Secondary outcome measures on patient level include pain, functional status, quality of life, health care utility, and productivity losses. Outcome measures on professional level include knowledge and attitude towards the guideline, and guideline adherence. A process evaluation for the implementation strategy will be performed among the health care providers and the patients. Furthermore, a qualitative subgroup analysis among patients with various ethnic backgrounds will be performed. This study will give insight into the (cost-) effectiveness of a multifaceted implementation strategy for the Dutch multidisciplinary guideline for non

    Because of its frequency, diverticular disease is a burden on health care systems. Only few formal guidelines covering all aspects of the disease exist. Here, some selected statements from the German guidelines are given. The guidelines include significant recommendations for the diagnosis and management of diverticular disease. Both diagnosis and management depend definitely on clear definitions of the situation of an individual patient. Therefore, a new classification is proposed that is based on earlier suggestions. An internationally established classification would not only enable better patient care but could also lead to studies with comparable results.

    The Builder Guidelines are designed to make simple, appropriate guidelines available to builders for their specific localities. Builders may select from passive solar and conservation strategies with different performance potentials. They can then compare the calculated results for their particular house design with a typical house in the same location. Algorithms used to develop the Builder Guidelines are described. The main algorithms used are the monthly solar ratio (SLR) method for winter heating, the diurnal heat capacity (DHC) method for temperature swing, and a new simplified calculation method (McCool) for summer cooling. This paper applies the algorithms to estimate the performance potential of passive solar strategies, and the annual heating and cooling loads of various combinations of conservation and passive solar strategies. The basis of the McCool method is described. All three methods are implemented in a microcomputer program used to generate the guideline numbers. Guidelines for Denver, Colorado, are used to illustrate the results. The structure of the guidelines and worksheet booklets are also presented. 5 refs., 3 tabs.

    Epetra is a package of classes for the construction and use of serial and distributed parallel linear algebra objects. It is one of the base packages in Trilinos. This document describes guidelines for Epetra coding style. The issues discussed here go beyond correct C++ syntax to address issues that make code more readable and self-consistent. The guidelines presented here are intended to aid current and future development of Epetra specifically. They reflect design decisions that were made in the early development stages of Epetra. Some of the guidelines are contrary to more commonly used conventions, but we choose to continue these practices for the purposes of self-consistency. These guidelines are intended to be complimentary to policies established in the Trilinos Developers Guide.

    1997-01-01

    Human-computer interaction (HCI) study is the region of intersection between psychology and the social sciences, on the one hand, and computer science and technology, on the other. HCI researchers analyze and design specific user interface technologies (e.g. pointing devices). They study and improve the processes of technology development (e.g. task analysis, design rationale). They develop and evaluate new applications of technology (e.g. word processors, digital libraries). Throughout the past two decades, HCI has progressively integrated its scientific concerns with the engineering goal of improving the usability of computer systems and applications, which has resulted in a body of technical knowledge and methodology. HCI continues to provide a challenging test domain for applying and developing psychological and social theory in the context of technology development and use.

    The application of adaptive design methodology within a clinical trial setting is becoming increasingly popular. However the application of these methods within trials is not being reported as adaptive designs hence making it more difficult to capture the emerging use of these designs. Within this review, we aim to understand how adaptive design methodology is being reported, whether these methods are explicitly stated as an 'adaptive design' or if it has to be inferred and to identify whether these methods are applied prospectively or concurrently. Three databases; Embase, Ovid and PubMed were chosen to conduct the literature search. The inclusion criteria for the review were phase II, phase III and phase II/III randomised controlled trials within the field of Oncology that published trial results in 2015. A variety of search terms related to adaptive designs were used. A total of 734 results were identified, after screening 54 were eligible. Adaptive designs were more commonly applied in phase III confirmatory trials. The majority of the papers performed an interim analysis, which included some sort of stopping criteria. Additionally only two papers explicitly stated the term 'adaptive design' and therefore for most of the papers, it had to be inferred that adaptive methods was applied. Sixty-five applications of adaptive design methods were applied, from which the most common method was an adaptation using group sequential methods. This review indicated that the reporting of adaptive design methodology within clinical trials needs improving. The proposed extension to the current CONSORT 2010 guidelines could help capture adaptive design methods. Furthermore provide an essential aid to those involved with clinical trials.

  10. Multiple metaphor environments: designing for diversity.

    Science.gov (United States)

    Akoumianakis, D; Stephanidis, C

    2003-01-15

    This paper advances a proposition for the engineering of interactive computer-based environments capable of exhibiting alternative interactive embodiments to cope with diversity in users, interaction platforms and usage contexts. Such systems are referred to as Multiple Metaphor Environments (MME). The theoretical underpinnings of an MME rely on a conception of HCI design as mapping functions in a machine-oriented language (target domain) to symbols in a user-oriented language (source domain), and vice versa. Such a conception, which is rooted in developments in communication theory and the philosophy of language, constitutes the baseline for formulating a proposal for the design of MME. The proposal comprises a set of engineering principles, process-oriented guidelines and design techniques intended to facilitate a detailed account of how interactive systems could be designed to cope with diversity. To aid the articulation of the various properties of MME, we refer to concrete case studies that provide exemplars of novel insights and promising design practices towards the specification of MME.

    Hanson, C. E.; Abbot, P.; Dyer, I.

    1993-01-01

    Noise levels from magnetically-levitated trains (maglev) at very high speed may be high enough to cause environmental noise impact in residential areas. Aeroacoustic sources dominate the sound at high speeds and guideway vibrations generate noticeable sound at low speed. In addition to high noise levels, the startle effect as a result of sudden onset of sound from a rapidly moving nearby maglev vehicle may lead to increased annoyance to neighbors of a maglev system. The report provides a base for determining the noise consequences and potential mitigation for a high speed maglev system in populated areas of the United States. Four areas are included in the study: (1) definition of noise sources; (2) development of noise criteria; (3) development of design guidelines; and (4) recommendations for a noise testing facility.

    The aim of this study is to investigate factors contributing to the failure of a randomized clinical trial designed to implement and test clinical practice guidelines for the treatment of depression in primary health care (PHC). Although the occurrence of depression is increasing globally, many patients with depression do not receive optimal treatment. Clinical practice guidelines for the treatment of depression, which aim to establish evidence-based clinical practice in health care, are often underused and in need of operationalization in and adaptation to clinical praxis. This study explores a failed clinical trial designed to implement and test treatment of depression in PHC in Sweden. Qualitative case study methodology was used. Semi-structured interviews were conducted with eight participants from the clinical trial researcher group and 11 health care professionals at five PHC units. Additionally, archival data (ie, documents, email correspondence, reports on the clinical trial) from the years 2007-2010 were analysed. The study identified barriers to the implementation of the clinical trial in the project characteristics, the medical professionals, the patients, and the social network, as well as in the organizational, economic and political context. The project increased staff workload and created tension as the PHC culture and the research activities clashed (eg, because of the systematic use of questionnaires and changes in scheduling and planning of patient visits). Furthermore, there was a perception that the PHC units' management did not sufficiently support the project and that the project lacked basic incentives for reaching a sustainable resolution. Despite efforts by the project managers to enhance and support implementation of the innovation, they were unable to overcome these barriers. The study illustrates the complexity and barriers of performing clinical trials in the PHC.

    Full Text Available Abstract background The pace of novel medical treatments and approaches to therapy has accelerated in recent years. Unfortunately, many potential therapeutic advances do not fulfil their promise when subjected to randomized controlled trials. It is therefore highly desirable to speed up the process of evaluating new treatment options, particularly in phase II and phase III trials. To help realize such an aim, in 2003, Royston and colleagues proposed a class of multi-arm, two-stage trial designs intended to eliminate poorly performing contenders at a first stage (point in time. Only treatments showing a predefined degree of advantage against a control treatment were allowed through to a second stage. Arms that survived the first-stage comparison on an intermediate outcome measure entered a second stage of patient accrual, culminating in comparisons against control on the definitive outcome measure. The intermediate outcome is typically on the causal pathway to the definitive outcome (i.e. the features that cause an intermediate event also tend to cause a definitive event, an example in cancer being progression-free and overall survival. Although the 2003 paper alluded to multi-arm trials, most of the essential design features concerned only two-arm trials. Here, we extend the two-arm designs to allow an arbitrary number of stages, thereby increasing flexibility by building in several 'looks' at the accumulating data. Such trials can terminate at any of the intermediate stages or the final stage. Methods We describe the trial design and the mathematics required to obtain the timing of the 'looks' and the overall significance level and power of the design. We support our results by extensive simulation studies. As an example, we discuss the design of the STAMPEDE trial in prostate cancer. Results The mathematical results on significance level and power are confirmed by the computer simulations. Our approach compares favourably with methodology

    Design fiction is an emergent field within HCI and interaction design, the understanding of which ultimately relies, so we argue, of an integrative account of poetics and design praxis. In this paper we give such an account. Initially, a precise definition of design fiction is given by drawing...... on the theory of possible worlds found within poetics. Further, we offer a method of practicing design fiction, which relies on the equal integration of literary practice with design practice. The use of this method is demonstrated by 4 design projects from a workshop set up in collaboration with a Danish...... author. All of this substantiates our notion of a poetics of practicing design fiction, and through our critical examination of related work we conclude on how our approach contribute to HCI and interaction design....

    Studies on the heat resistance of dairy pathogens are a vital part of assessing the safety of dairy products. However, harmonized methodology for the study of heat resistance of food pathogens is lacking, even though there is a need for such harmonized experimental design protocols and for harmonized validation procedures for heat treatment studies. Such an approach is of particular importance to allow international agreement on appropriate risk management of emerging potential hazards for human and animal health. This paper is working toward establishment of a harmonized protocol for the study of the heat resistance of pathogens, identifying critical issues for establishment of internationally agreed protocols, including a harmonized framework for reporting and interpretation of heat inactivation studies of potentially pathogenic microorganisms.

    2010-02-01

    Full Text Available Abstract Background There is growing interest in the use of cognitive, behavioural, and organisational theories in implementation research. However, the extent of use of theory in implementation research is uncertain. Methods We conducted a systematic review of use of theory in 235 rigorous evaluations of guideline dissemination and implementation studies published between 1966 and 1998. Use of theory was classified according to type of use (explicitly theory based, some conceptual basis, and theoretical construct used and stage of use (choice/design of intervention, process/mediators/moderators, and post hoc/explanation. Results Fifty-three of 235 studies (22.5% were judged to have employed theories, including 14 studies that explicitly used theory. The majority of studies (n = 42 used only one theory; the maximum number of theories employed by any study was three. Twenty-five different theories were used. A small number of theories accounted for the majority of theory use including PRECEDE (Predisposing, Reinforcing, and Enabling Constructs in Educational Diagnosis and Evaluation, diffusion of innovations, information overload and social marketing (academic detailing. Conclusions There was poor justification of choice of intervention and use of theory in implementation research in the identified studies until at least 1998. Future research should explicitly identify the justification for the interventions. Greater use of explicit theory to understand barriers, design interventions, and explore mediating pathways and moderators is needed to advance the science of implementation research.

  13. Design guidelines, scan behavior and characteristic mode analysis for a class of ultra-wideband microstrip patch antennas

    Science.gov (United States)

    Elsewe, Mohamed Mahmoud

    Ultra-wideband (UWB), low-profile microstrip patch antennas and phased arrays have their niche in many wireless communication and medical applications. In recent years, the U-slot patch antenna established itself as a versatile antenna that can be fine-tuned for ultra-wideband operations. The L-shaped probe feeding method has additionally led to improved impedance bandwidth for the U-slot patch antenna. The L-probe's simple structure together with its low production cost makes it an attractive feeding method for the U-slot microstrip patch antenna. In phased arrays, scan blindness due to surface wave excitations can reduce the scan bandwidth range. By reducing the mutual coupling between array elements, the scan blindness effects will be reduced. Also, by reducing the sidelobe levels and minimizing the effect of grating lobes in phased arrays, the array's scan performance and power efficiency can be improved. In this dissertation, (1) a parametric study is performed on epsilon r = 2.2 and 4.5 substrates for the design of ideal L-probe feed dimensions with optimum impedance bandwidth. Results show that first-pass optimum impedance bandwidth of over 50% is achieved using the ideal L-probe feed dimensions. (2) The mutual coupling between a 2-element UWB microstrip array using different patch orientations and U-slot topologies is examined for epsilonr = 2.2 and 4.5 substrates to reduce the effect of scan blindness. Results, for epsilonr = 2.2 substrate, indicate that a diamond patch orientation with opposite U-slot topology presents the least coupling between the array elements. For epsilonr = 4.5 substrate, the E-plane patch orientation with parallel U-slot topology has the least coupling. (3) The scan behavior of 5x5 planar phased arrays using different patch orientations and U-slot topologies is examined for epsilonr = 2.2 substrate. Results indicate that blind spots are less prevalent in the diamond patch orientation and more prevalent in the E-plane patch

  14. Adaptive software architecture based on confident HCI for the deployment of sensitive services in Smart Homes.

    Vega-Barbas, Mario; Pau, Iván; Martín-Ruiz, María Luisa; Seoane, Fernando

    2015-03-25

    Smart spaces foster the development of natural and appropriate forms of human-computer interaction by taking advantage of home customization. The interaction potential of the Smart Home, which is a special type of smart space, is of particular interest in fields in which the acceptance of new technologies is limited and restrictive. The integration of smart home design patterns with sensitive solutions can increase user acceptance. In this paper, we present the main challenges that have been identified in the literature for the successful deployment of sensitive services (e.g., telemedicine and assistive services) in smart spaces and a software architecture that models the functionalities of a Smart Home platform that are required to maintain and support such sensitive services. This architecture emphasizes user interaction as a key concept to facilitate the acceptance of sensitive services by end-users and utilizes activity theory to support its innovative design. The application of activity theory to the architecture eases the handling of novel concepts, such as understanding of the system by patients at home or the affordability of assistive services. Finally, we provide a proof-of-concept implementation of the architecture and compare the results with other architectures from the literature.

Ambient media are media that are embedded throughout our natural environment - location based services, context awareness, emotional responsive interfaces, touch and gesture based interfaces, haptics and biometrics, sensor perception, mobile devices, and smart data mining are the technological enabler for smart media environments. The latest trends from emotional computation, affective computation, and tangible media lay the foundations for this new and exciting form of media existing far beyond screen concepts and mouse based interaction metaphors. The tutorial trains participants in the basic technologies as tools for the design of new interactive ‘ambient’ environments. It presents case studies and latest research results in the field of ambient media, ranging from ambient assisting living, user experience design, user contributed content, and mobile services. After the tutorial the participants should understand the principles of ambient media with its underlying concepts and methods, especially emphasizing human-computer-interaction. As roundup, the tutorial presents a more visionary viewpoint to the future of media technology: the use of biological metaphors for interactive environments (biomedia).

    Full Text Available Smart spaces foster the development of natural and appropriate forms of human-computer interaction by taking advantage of home customization. The interaction potential of the Smart Home, which is a special type of smart space, is of particular interest in fields in which the acceptance of new technologies is limited and restrictive. The integration of smart home design patterns with sensitive solutions can increase user acceptance. In this paper, we present the main challenges that have been identified in the literature for the successful deployment of sensitive services (e.g., telemedicine and assistive services in smart spaces and a software architecture that models the functionalities of a Smart Home platform that are required to maintain and support such sensitive services. This architecture emphasizes user interaction as a key concept to facilitate the acceptance of sensitive services by end-users and utilizes activity theory to support its innovative design. The application of activity theory to the architecture eases the handling of novel concepts, such as understanding of the system by patients at home or the affordability of assistive services. Finally, we provide a proof-of-concept implementation of the architecture and compare the results with other architectures from the literature.

  2. Choreographic Inscriptions: A Framework for Exploring Sociomaterial Influences on Qualities of Movement for HCI

    Directory of Open Access Journals (Sweden)

    Lian Loke

    2016-01-01

    Full Text Available With the rise of ubiquitous computing technologies in everyday life, the daily actions of people are becoming ever more choreographed by the interactions available through technology. By combining the notion of inscriptions from actor–network theory and the qualitative descriptors of movement from Laban movement analysis, an analytic framework is proposed for exploring how the interplay of material and social inscriptions gives rise to movement patterns and behaviors, translated into choreographic inscriptions described with Laban effort and shape. It is demonstrated through a case study of an affective gesture mobile device. The framework provides an understanding of (a how movement qualities are shaped by social and material inscriptions, (b how the relative strength of inscriptions on movements may change according to different settings and user appropriation over time, and (c how transforming inscriptions by design across different mediums can generate action spaces with varying degrees of openness.

    Objective:To analyze the effect of fasudil combined with conventional therapy on nerve and blood coagulation function as well as Hcy metabolism in patients with acute cerebral infarction. Methods:80 patients with acute cerebral infarction treated in our hospital between January 2013 and January 2013 were selected as the research subjects and divided into observation group (n = 40) and control group (n = 40) according to the random number table. Control group received conventional therapy and observation group received fasudil combined with conventional therapy. After 14 d of treatment, the levels of cerebral blood perfusion parameters, nerve function indexes, platelet function indexes and homocysteine (Hcy) of two groups of patients were determined.Results:After 14 d of treatment, middle cerebral artery and basilar artery peak systolic flow velocity (Vs), low diastolic flow velocity (Vd) and mean flow velocity (Vm) levels of observation group were higher than those of control group (P<0.05); serum nerve function indexes brain-derived neurotrophic factor (BDNF) and nerve growth factor (NGF) content were higher than those of control group (P<0.05) while phosphatidic acid (PA), neuron-specific enolase (NSE), S100β protein (S100β), and substantia nigra divalent metal transporter 1 (DMT1) content were lower than those of control group (P<0.05); serum platelet function indexes platelet activation-dependent granule membrane protein-140 (GMP-140), fibrinogen receptor-1 (PAC-1), platelet activating factor (PAF) and platelet-derived growth factor BB (PDGF-BB) content were lower than those of control group (P<0.05); serum Hcy content was lower than that of control group (P<0.05).Conclusions:Fasudil combined with conventional therapy can optimize the nerve function and blood coagulation function in patients with acute cerebral infarction, and also plays a positive role in reducing Hcy levels.

  4. Crystal structure and activity of protein L-isoaspartyl-O-methyltransferase from Vibrio cholerae, and the effect of AdoHcy binding.

    The repair enzyme Protein L-isoaspartyl-O-methyltransferase (PIMT) is widely distributed in various organisms. PIMT catalyzes S-adenosylmethionine (AdoMet) dependent methylation of abnormal L-isoaspartyl residues, formed by the deamidation of asparagines and isomerization of aspartates. We report the crystal structure of PIMT of Vibrio cholerae (VcPIMT), the aetiological agent for cholera, complexed with the demethylated cofactor S-adenosyl-L-homocysteine (AdoHcy) to 2.05 Å resolution. A stretch of residues (39-58), lining the substrate-binding site, is disordered. Urea-induced unfolding free energy for apo and VcPIMT-AdoHcy complex reveals greater stability for the cofactor-bound protein. The kinetic parameters for the methyltransferase activity of the recombinant VcPIMT was determined using a continuous spectrophotometric color-based assay using the peptide substrate [VYP(L-isoD)HA]. The enzyme exhibited activity higher than the Escherichia coli enzyme and closer to those from thermophilic bacteria and the mammalian source. The association constant for substrate binding is 2.29 × 10(6) M(-1), quite similar to that for AdoHcy. The crystal structure and the model of the peptide-bound structure indicate that the majority of the interactions used for cofactor/substrate binding are provided by the main-chain atoms. Evolutionary relationships derived based on a phylogenetic tree constructed using the PIMT sequences are in conformity with the crystal structures of nine AdoHcy-bound PIMTs.

  7. The use of analytical models in human-computer interface design

    Science.gov (United States)

    Gugerty, Leo

    1993-01-01

    Recently, a large number of human-computer interface (HCI) researchers have investigated building analytical models of the user, which are often implemented as computer models. These models simulate the cognitive processes and task knowledge of the user in ways that allow a researcher or designer to estimate various aspects of an interface's usability, such as when user errors are likely to occur. This information can lead to design improvements. Analytical models can supplement design guidelines by providing designers rigorous ways of analyzing the information-processing requirements of specific tasks (i.e., task analysis). These models offer the potential of improving early designs and replacing some of the early phases of usability testing, thus reducing the cost of interface design. This paper describes some of the many analytical models that are currently being developed and evaluates the usefulness of analytical models for human-computer interface design. This paper will focus on computational, analytical models, such as the GOMS model, rather than less formal, verbal models, because the more exact predictions and task descriptions of computational models may be useful to designers. The paper also discusses some of the practical requirements for using analytical models in complex design organizations such as NASA.

    2009-12-01

    Full Text Available Abstract Background Occupational health professionals may play an important role in preventive health promotion activities for employees. However, due to a lack of knowledge and evidence- and practice based methods and strategies, interventions are hardly being implemented by occupational physicians to date. The aim of the Balance@Work project is to develop, evaluate, and implement an occupational health guideline aimed at the prevention of weight gain among employees. Methods Following the guideline development protocol of the Netherlands Society of Occupational Medicine and the Intervention Mapping protocol, the guideline was developed based on literature, interviews with relevant stakeholders, and consensus among an expert group. The guideline consists of an individual and an environmental component. The individual component includes recommendations for occupational physicians on how to promote physical activity and healthy dietary behavior based on principles of motivational interviewing. The environmental component contains an obesogenic environment assessment tool. The guideline is evaluated in a randomised controlled trial among 20 occupational physicians. Occupational physicians in the intervention group apply the guideline to eligible workers during 6 months. Occupational physicians in the control group provide care as usual. Measurements take place at baseline and 6, 12, and 18 months thereafter. Primary outcome measures include waist circumference, daily physical activity and dietary behavior. Secondary outcome measures include sedentary behavior, determinants of behavior change, body weight and body mass index, cardiovascular disease risk profile, and quality of life. Additionally, productivity, absenteeism, and cost-effectiveness are assessed. Discussion Improving workers' daily physical activity and dietary behavior may prevent weight gain and subsequently improve workers' health, increase productivity, and reduce absenteeism

    A synthesis of recent research and developments on intelligent adaptive systems from the HF (human factors) and HCI (human-computer interaction) domains, this book provides integrated design guidance and recommendations for researchers and system developers. It addresses a recognized lack of integration between the HF and HCI research communities, which has led to inconsistencies between the research approaches adopted, and a lack of exploitation of research from one field by the other. The book establishes design guidance through the review of conceptual frameworks, analytical methodologies,

    Full Text Available Pre-eclampsia is a pregnancy-related multi-systemic hypertensive disorder and affects at least 5% of pregnancies. This randomized clinical trial aimed at assessing the effect of low doses and high doses of folic acid on homocysteine (Hcy levels, blood pressure, urea, creatinine and neonatal outcome. A randomized clinical trial was done at Alzahra Teaching Hospital, Tabriz University of Medical Sciences from April 2008 to March 2013. Four-hundred and sixty nulliparous pregnant women were randomly assigned into two groups. Group 1 (n = 230 received 0.5 mg of folic acid and group 2 (n = 230 received 5 mg of folic acid per daily. They were followed until delivery. Blood pressure and laboratory changes, including plasma Hcy levels, were measured and compared between the groups. Homocysteine concentrations were significantly higher at the time of delivery in group 1 (13.17±3.89 μmol/l than in group 2 (10.31±3.54, μmol/l (p<0.001. No statistically significant differences were observed in systolic and diastolic blood pressure (p = 0.84 and 0.15, respectively. Birth weight was significantly higher in group 2 (p = 0.031 and early abortion was significantly higher in group 1 than group 2 (p = 0.001. This study has provided evidence that a high dosage of folic acid supplements throughout pregnancy reduces Hcy concentrations at the time of delivery.Iranian Registry of Clinical Trials IRCT201402175283N9.

    在本工作中,我们以制备纯水相检测的纳米探针为目标,以二氧化硅纳米粒子作为载体,以含特异性检测基团的长发光寿命的磷光铱配合物作为信号单元,通过共价键接枝方法得到几种纳米探针.采用SEM 、TEM 、SAXRD和氮气吸附等表征方法对纳米探针的表面形貌和内部结构进行表征,并用磷光发射光谱研究基于不同载体所得到的纳米探针的光物理性质以及对高半胱氨酸(Hcy)和半胱氨酸(Cys)的响应性,最后通过理论计算对其响应机理进行探讨.实验结果表明,以MCM-41作为载体的杂化纳米探针具有更强的发光强度和更好的响应性,并且在纯水体系中实现了对半胱氨酸和高半胱氨酸的高选择性检测.%In this work, we designed and fabricated a series of new nanoprobes by using the high specific surface area and good biocompatibility of mesoporous silica nanoparticles as a probe carrier and the long lifetime luminescence of phosphorescent complexes as signal unit. The structures and physical properties of prepared nanoprobes were characterized by SEM, TEM, XRD and nitrogen adsorption/desorption isotherms. Spectrophotometric determination was performed in phosphate buffer saline (PBS) buffer for Hcy/Cys sensing. To further understand the response mechanism, the effect of the aldehyde (CHO) group on the photophysical properties was calculated by using TDDFT calculation method. The result demonstrated that the as-prepared nanoprobe exhibited high selectivity for Hey and Cys in pure PBS, which provides the advantage in developing excellent phosphorescent cellular probes for practical applications.

    2007-09-30

    Task 5 of the collaborative effort between ORNL, Brazil, and Westinghouse for the International Nuclear Energy Research Initiative entitled “Development of Advanced Instrumentation and Control for an Integrated Primary System Reactor” focuses on operator control and protection system interaction, with particular emphasis on developing emergency response guidelines (ERGs). As in the earlier tasks, we will use the IRIS plant as a specific example of an integrated primary system reactor (IPSR) design. The present state of the IRIS plant design – specifically, the lack of a detailed secondary system design – precludes establishing detailed emergency procedures at this time. However, we can create a structure for their eventual development. This report summarizes our progress to date. Section 1.2 describes the scope of this effort. Section 2 compares IPSR ERG development to the recent AP1000 effort, and identifies three key plant differences that affect the ERGs and control room designs. The next three sections investigate these differences in more detail. Section 3 reviews the IRIS Safety-by-Design™ philosophy and its impact on the ERGs. Section 4 looks at differences between the IRIS and traditional loop PWR I&C Systems, and considers their implications for both control room design and ERG development. Section 5 examines the implications of having one operating staff control multiple reactor units. Section 6 provides sample IRIS emergency operating procedures (EOPs). Section 7 summarizes our conclusions.

    To (1) evaluate the GoodOD guideline for ontology development by applying the OQuaRE evaluation method and metrics to the ontology artefacts that were produced by students in a randomized controlled trial, and (2) informally compare the OQuaRE evaluation method with gold standard and competency questions based evaluation methods, respectively. In the last decades many methods for ontology construction and ontology evaluation have been proposed. However, none of them has become a standard and there is no empirical evidence of comparative evaluation of such methods. This paper brings together GoodOD and OQuaRE. GoodOD is a guideline for developing robust ontologies. It was previously evaluated in a randomized controlled trial employing metrics based on gold standard ontologies and competency questions as outcome parameters. OQuaRE is a method for ontology quality evaluation which adapts the SQuaRE standard for software product quality to ontologies and has been successfully used for evaluating the quality of ontologies. In this paper, we evaluate the effect of training in ontology construction based on the GoodOD guideline within the OQuaRE quality evaluation framework and compare the results with those obtained for the previous studies based on the same data. Our results show a significant effect of the GoodOD training over developed ontologies by topics: (a) a highly significant effect was detected in three topics from the analysis of the ontologies of untrained and trained students; (b) both positive and negative training effects with respect to the gold standard were found for five topics. The GoodOD guideline had a significant effect over the quality of the ontologies developed. Our results show that GoodOD ontologies can be effectively evaluated using OQuaRE and that OQuaRE is able to provide additional useful information about the quality of the GoodOD ontologies.

    2011-04-01

    The Inventory of Cancer Guidelines (ICG) was designed to mitigate challenges associated with inconsistencies in the quality of cancer guidelines, keeping guidelines current and the duplication of effort in guideline development. The ICG is a searchable database of quality-appraised guidelines in cancer control that also includes designations of guidelines in progress, those in need of an update and those currently being updated. From a clinical perspective, the majority of the completed guidelines target breast, lung, colorectal and prostate cancers, and focus on the treatment stage of the cancer continuum. There is considerable variability in guideline quality both within and across guideline developers, as measured by the Appraisal of Guidelines for Research and Evaluation II. Quality domains of applicability and editorial independence are the guideline quality domains that score the poorest. While the ability to inform on the status of cancer control guidelines is important, the real potential of the ICG is in its ability to leverage positive change in the guideline enterprise. Pilot projects are underway to use data from the ICG to tailor audit and feedback interventions for guideline developers and to pursue collaborative updating and guideline adaptation initiatives, using the ICG as the platform from which these partnerships can evolve.

    2002-01-01

    This paper describes the demands on therapeutic guideline production and a production system (SISMO) designed to cope with these demands. Guidelines are intended for use within a range of clinical information systems and vary in their content, style, intended audience and structure. Complex medical information makes up the content of guidelines and is subsequently viewed in complex and varying environments, on a variety of devices. The functionality of SISMO allows guideline content providers to produce content in a way that is sympathetic to the traditional means of writing guidelines, while also allowing guideline structure to be developed.

  7. Human-computer interface design

    Energy Technology Data Exchange (ETDEWEB)

    Bowser, S.E.

    1995-04-01

    Modern military forces assume that computer-based information is reliable, timely, available, usable, and shared. The importance of computer-based information is based on the assumption that {open_quotes}shared situation awareness, coupled with the ability to conduct continuous operations, will allow information age armies to observe, decide, and act faster, more correctly and more precisely than their enemies.{close_quotes} (Sullivan and Dubik 1994). Human-Computer Interface (HCI) design standardization is critical to the realization of the previously stated assumptions. Given that a key factor of a high-performance, high-reliability system is an easy-to-use, effective design of the interface between the hardware, software, and the user, it follows logically that the interface between the computer and the military user is critical to the success of the information-age military. The proliferation of computer technology has resulted in the development of an extensive variety of computer-based systems and the implementation of varying HCI styles on these systems. To accommodate the continued growth in computer-based systems, minimize HCI diversity, and improve system performance and reliability, the U.S. Department of Defense (DoD) is continuing to adopt interface standards for developing computer-based systems.

Methods Serum was collected from 55 patients with depression (depression group) and 30 health adults (control group). The levels of serum CRP and CER were determined by rate nephelometry. Serum anti - CCP concentration was measured by enzymatic - linked immu-nosorbent assay (ELISA) and serum Hcy was detected by enzyme method. The differences of serum CRP, CER, Hcy and anti -CCP levels were compared between the depression group and the control group. Results Compared with the control group, the serum CRP level of the depression group was not statistically different(P >0.05), while the serum CER concentration was significantly decreased ( P < 0.05 ) and serum Hcy and anti - CCP were markedly incrcascd( P < 0. 05 ) . Conclusions Immu-nological inflammation and autoimmune reaction do exist in depression patients. CER, Hcy and anti - CCP may all participate in the pathological process of depression.

    Full Text Available In a recent survey, Canadian Thoracic Society (CTS members indicated that they feel our association should be involved in the production of guidelines (1. There is evidence in the literature that suggests guidelines can have some effect in changing behaviour, although this is variable and modest at best. Certainly, the production of guidelines is not without costs, particularly in time spent by experts in reviewing the literature and producing them. For good reasons, delays frequently occur in their production, often leading to recommendations that may be outdated. People sometimes forget that one of the most important reasons for producing guidelines is to identify questions that require future research.

    Full Text Available Abstract Background One-half of patients with cancer have pain. In nearly one out of two cancer patients with pain, this was undertreated. Inadequate pain control still remains an important problem in this group of patients. Therefore, in 2008 a national, evidence-based multidisciplinary clinical practice guideline 'pain in patients with cancer' has been developed. Yet, publishing a guideline is not enough. Implementation is needed to improve pain management. An innovative implementation strategy, Short Message Service with Interactive Voice Response (SVS-IVR, has been developed and pilot tested. This study aims to evaluate on effectiveness of this strategy to improve pain reporting, pain measurement and adequate pain therapy. In addition, whether the active role of the patient and involvement of caregivers in pain management may change. Methods/design A cluster randomised controlled trial with two arms will be performed in six oncology outpatient clinics of hospitals in the Southeastern region of the Netherlands, with three hospitals in the intervention and three in the control condition. Follow-up measurements will be conducted in all hospitals to study the long-term effect of the intervention. The intervention includes training of professionals (medical oncologists, nurses, and general practitioners and SMS-IVR to report pain in patients with cancer to improve pain reporting by patients, pain management by medical oncologists, nurses, and general practitioners, and decrease pain intensity. Discussion This innovative implementation strategy with technical tools and the involvement of patients, may enhance the use of the guideline 'pain in patients with cancer' for pain management. Short Message Service alerts may serve as a tool to support self-management of patients. Therefore, the SMS-IVR intervention may increase the feeling of having control over one's life.

    Contemporary health research has come under close scrutiny, exposing alarming flaws in the reporting of research. The reporting guidelines can aid in identification of poorly reported studies and can bring transparency to health research. The guidelines also help journal editors, peer reviewers, funding agencies, and readers to better discern health research. Reporting guidelines encourage accurate and thorough reporting of fundamental aspects of health research so that the results of studies can be replicated by others. Reporting guidelines are potent tools to improve the practice of research and in reducing reporting bias. For the present review, both electronic and manual literature search was carried out. Electronic databases like PubMed, MEDLINE, EBSCO host, and Science Direct were searched for extracting relevant articles. Various key words and their combinations were used for literature search like reporting guidelines, checklist, research, publishing standards, study design, medicine, and dentistry. The search results were scrutinized for relevance to the topic and only full text articles in English were incorporated. Various reporting guidelines were identified and grouped under headings based on study design. This review article attempts to highlight the various reporting guidelines in literature relating to health research, its potential applications, and its limitations.

    1994-07-01

    The US Environmental Protection Agency (EPA) promulgated National Emission Standards other than Radon from US Department of Energy (DOE) Facilities (40 CFR 61, Subpart H) on December 15, 1989. The regulations specify procedures, equipment, and test methods that.are to be used to measure radionuclide emissions from exhaust stacks that are designated as National Emission Standards for Hazardous Air Pollutant (NESHAP) stacks. Designated NESHAP stacks are those that have the potential to cause any member of the public to receive an effective dose equivalent (EDE) greater than or equal to 0.1 mrem/year, assuming all emission controls were removed. Tank Farms currently has 33 exhaust stacks, 15 of which are designated NESHAP stacks. This document assesses the compliance status of the monitoring and sampling systems for the designated NESHAP stacks.

    These European Guidelines for Workplace Drug Testing in Urine have been prepared and updated by the European Workplace Drug Testing Society (EWDTS). The first version of these urine guidelines was published in 2002. Since then, the guidelines have been followed by many laboratories in different European countries and their role has been essential particularly in countries lacking legislation for workplace drug testing. In 2014, the EWDTS started a guidelines updating project and published a new version of the urine guidelines in 2015. Here we represent this updated version of the urine guidelines. The European Guidelines are designed to establish best practice procedures whilst allowing individual countries to operate within the requirements of national customs and legislation. The EWDTS recommends that all European laboratories that undertake legally defensible workplace drug testing should use these guidelines as a template for accreditation.

    2003-01-01

    Geropsychotherapy researchers have established specific methods that improve the reliability and generalizability of the data from this research. To date, there has been little formal dissemination of these methods. The authors present guidelines for the optimal conduct of psychotherapy research in older adults, which include selection of age-appropriate psychotherapies and control conditions, use of consumer-based methods for recruitment, evaluation of age-related treatment processes and outcomes, and adjusting the research design to accommodate age-specific life events and provide examples of how each guideline was used in their psychotherapy studies. Psychotherapy research with older adults has benefited from methodological advances that improve our ability to ascertain the impact of psychotherapy on late-life disorders. However, the field is still in need of better outcome and process measures, methods for measuring the therapeutic content of non-psychotherapy encounters, and methods for determining the impact of choice of treatment on outcome.

    1982-01-01

    The Mosaic Transistor Array is an extension of the STAR system developed by NASA which has dedicated field cells designed to be specifically used in semicustom microprocessor applications. The Sandia radiation hard bulk CMOS process is utilized in order to satisfy the requirements of space flights. A design philosophy is developed which utilizes the strengths and recognizes the weaknesses of the Sandia process. A style of circuitry is developed which incorporates the low power and high drive capability of CMOS. In addition the density achieved is better than that for classic CMOS, although not as good as for NMOS. The basic logic functions for a data path are designed with compatible interface to the STAR grid system. In this manner either random logic or PLA type structures can be utilized for the control logic.

    从教学设计的视角看,有效教学的基本要义涉及促进一般发展与特色发展相得益彰,共同发展与差异发展协调平衡;形成知己、知事与知人相统一的专长;实现可应用于具体学科领域的一般原则或策略的具体迁移;强调学习中生成意义,以满足学习本质上内外协调、表里贯通的要求;坚持学教统一,调动师生两个方面的积极性,努力做到从扶到放、扶放有度,逐渐撤除支架,同时致力于创设友好的学习环境,使之物理环境宜人、心理环境舒畅与技术环境通达;教学时应面向完整任务,聚焦解决问题,通过整体设计与有序设计的结合,真正实现教学目标、教学方法和教学评估三者匹配一致。%From the perspective of instructional design, the guideline of effective instruction involves promoting mutual complement of general development and individuality development, and accordant balance of jointly development and different development; forming consistent expertise of "know self", "know task" and "know others"; achieving practical general principle or specific transfer of knowledge to be used in concrete subject fields; emphasizing meaning generation during learning process to meet the demand of intrinsic and extrinsic unity of learning essence. It also requires insistence in integration of learning and teaching to mobilize the initiative and enthusiasm of both teachers and students. Meanwhile the guideline also devotes to create a friendly learning environment, including pleasant physical environment, safe psychological environment and accessible technological environment. Last but not the least, the guideline needs to be oriented towards a whole task and focused on problem solving. By the combination of systematic design, instructional objectives, instructional method and instructional evaluation can be genuinely matched up with each other in conformity.

  11. [Guidelines for clinical practice].

    Vleugels, A M

    1997-01-01

    Clinical practice guidelines are systematically developed statements that are intended to support medical decision making in well-defined clinical situations. Essentially, their object is to reduce the variability in medical practice, to improve quality, and to make appropriated control of the financial resources possible. Internationally, ever more organisations, associations, and institutions are concerned with the development of guidelines in many different areas of care. Making implicit knowledge explicit is one of the associated advantages of guidelines: they have a potential utility in training, in process evaluation, and in the reevaluation of outcome studies. In liability issues, their existence has a double effect: they can be used to justify medical behaviour, and they constitute a generally accepted reference point. A derivative problem is the legal liability of the compilers of the guidelines. The principle of the guideline approach can be challenged academically: science cannot give a definition of optimal care with absolute certainty. What is called objectivity often rests on methodologically disputable analyses; also the opinion of opinion leaders is not always a guarantee for scientific soundness. Moreover, patients are not all identical: biological variability, situational factors, patient expectations, and other elements play a role in this differentiation. Clinicians are often hesitant with respect to clinical guidelines: they are afraid of cookbook medicine and curtailment of their professional autonomy. Patients fear reduction of individualization of care and the use of guidelines as a rationing instrument. The effects of the introduction of clinical practice guidelines on medical practice, on the results and on the cost of care vary but are generally considered to be favourable. The choice of appropriate strategies in development, dissemination, and implementation turns out to be of critical importance. The article ends with concrete

  12. Strategy Guideline: HVAC Equipment Sizing

    Energy Technology Data Exchange (ETDEWEB)

    Burdick, A.

    2012-02-01

    The heating, ventilation, and air conditioning (HVAC) system is arguably the most complex system installed in a house and is a substantial component of the total house energy use. A right-sized HVAC system will provide the desired occupant comfort and will run efficiently. This Strategy Guideline discusses the information needed to initially select the equipment for a properly designed HVAC system. Right-sizing of an HVAC system involves the selection of equipment and the design of the air distribution system to meet the accurate predicted heating and cooling loads of the house. Right-sizing the HVAC system begins with an accurate understanding of the heating and cooling loads on a space; however, a full HVAC design involves more than just the load estimate calculation - the load calculation is the first step of the iterative HVAC design procedure. This guide describes the equipment selection of a split system air conditioner and furnace for an example house in Chicago, IL as well as a heat pump system for an example house in Orlando, Florida. The required heating and cooling load information for the two example houses was developed in the Department of Energy Building America Strategy Guideline: Accurate Heating and Cooling Load Calculations.

Methods Biochemical method was used to detect the content of LP (a) , Hcy and CRP in peripheral blood within experiment groups (60 cases) and control groups (30 cases). Results The contents of LP(a)、HCY and CRP in AMI patients are obviously higher than those in control group (P=0.001, P=0.001和P=0.007). After treatment, HCY and CRP concentrations decreased markedly in AMI patients (P=0.001). As for Lp(a) there was no signiifcant difference after treatment. Conclusion There is a relationship between high Lp(a), Hcy and the occurring of AMI. The former two detected simultaneously with CRP can be used as the auxiliary indicators in preventing AMI and observing its curative effect.

  18. Hybrid specification, storage, retrieval and runtime application of clinical guidelines.

    2006-06-01

    Clinical guidelines are a major tool in improving the quality of medical care. However, most guidelines are in free text, are not machine-comprehensible and are not easily accessible to clinicians at the point of care. We have designed and implemented a web-based, modular, distributed architecture, the Digital Electronic Guideline Library (DeGeL), which facilitates gradual conversion of clinical guidelines from text to a formal representation in the chosen target guideline ontology. The architecture supports guideline classification, semantic markup, context-sensitive search, browsing, run-time application and retrospective quality assessment. The DeGeL hybrid meta-ontology includes elements common to all guideline ontologies, such as semantic classification and domain knowledge; it also includes four content-representation formats: free text, semi-structured text, semi-formal representation and a formal representation. These formats support increasingly sophisticated computational tasks. Guidelines can thus be in a hybrid representation in which guidelines, and even parts of the same guideline, might exist at different formalisation levels. We have also developed and rigorously evaluated a methodology and an associated web-based tool, Uruz, for gradually structuring and semi-formalising free-text clinical guidelines. Finally, we have designed, implemented and evaluated a new approach, the hybrid runtime application model, for supporting runtime application of clinical guidelines that are not necessarily in a machine-comprehensible format; in particular, when the guideline is in a semi-formal representation and the patient's data are either in an electronic medical record or in a paper format. The tool implementing this new approach, the Spock module, is customised at this point to the Asbru guideline specification language and exploits the hybrid structure of guidelines in DeGeL. The Spock module also exploits our temporal-abstraction mediator to the patient
