  2. Participatory Design of Multi-Use Platforms at Sea

    Directory of Open Access Journals (Sweden)

    Sander van den Burg

    2016-01-01

    Full Text Available European oceans are subject to rapid development. New activities such as aquaculture and ocean energy have gained importance. This triggers interest in “multi-use platforms at sea” (MUPS, i.e., areas at sea in which different activities are combined. MUPS are complex features with regards to technology, governance, and financial, socioeconomic, and environmental aspects. To identify realistic and sustainable solutions and designs for MUPS, the MERMAID project applied a participatory design process (PDP involving a range of stakeholders representing companies, authorities, researchers, and NGOs. This paper evaluates if and how the participatory design process contributed to the design of multi-use platforms. It is based on interviews with the managers of the case study sites and a questionnaire administered to all stakeholders participating in the PDP workshops. Analyzing the four case studies, we conclude that the participatory design process has had a valuable contribution to the development of the four different designs of MUPS, even though the preconditions for carrying out a participatory design process differed between sites. In all four cases, the process has been beneficial in generating new and shared knowledge. It brought new design issues to the table and increased knowledge and understanding among the different stakeholders.

  5. Participatory pattern workshops: a methodology for open learning design inquiry

    Directory of Open Access Journals (Sweden)

    Niall Winters

    2012-08-01

    Full Text Available In order to promote pedagogically informed use of technology, educators need to develop an active, inquisitive, design-oriented mindset. Design Patterns have been demonstrated as powerful mediators of theory-praxis conversations yet widespread adoption by the practitioner community remains a challenge. Over several years, the authors and their colleagues have facilitated many workshops in which participants shared experiences, captured these as design narratives, extracting design patterns, and applied them to novel teaching challenges represented as design scenarios. This paper presents the core elements of the methodology that emerged from these workshops: the Participatory Patterns Workshops (PPW methodology.

  8. The design game in Participatory Design and design education

    DEFF Research Database (Denmark)

    Törpel, Bettina

    2006-01-01

    In this contribution, the design game as a method in Participatory Design is discussed. The focus lies on the organizational design game. For using the design game relations of power, socio-technical textures and forms of work and organization are treated as concerns that need to be addressed...... carefully. Cases from student projects are used as illustrating examples; work environments were redesigned and design games played. It turns out that degrees of freedom are present for the choice of (gaming) method as well as the ways of using the selected method. These degrees of freedom should be used...... in a way that will be labeled as »interested«, rather than in a way labeled as »taking for granted«. It is not possible to guarantee an interested and beneficial approach; yet the paper argues on the grounds that reflective gaming practice can be supportive in this direction....

  9. Five Enunciations of Empowerment i Participatory Design

    DEFF Research Database (Denmark)

    Ertner, Sara Marie; Kragelund, Anne Mie; Malmborg, Lone

    2010-01-01

    Participatory design has been defined as having 'user's democratic participation and empowerment at its core' (Correia and Yusop, 2008). The PD discourse has a strong moral and rhetorical claim by its emphasis on users' empowerment. This paper is a result of a student project, guided by a curiosity...... about how empowerment is enunciated in the PD field today. In a literature-review of academic papers from the proceedings of PDC 2008 we found that empowerment is enunciated in five different ways which can be translated into 5 categories: 1) Specific user groups 2) Direct democracy 3) The users......' position 4) Researchers' practice 5) Reflexive practice. These categories exist conjointly in the literature and suggest that empowerment is not just a moral and politically correct design goal, but a challenged and complex activity....

  12. Applying Participatory Methods to Address Motivational Aspects in Informal Workplace

    Directory of Open Access Journals (Sweden)

    Teresa Holocher

    2011-02-01

    Full Text Available Motivational aspects are core to successful knowledge sharing and collaborative learning experiences. However, it still remains one of the great challenges to overcome motivational barriers when it comes to introducing information systems for collaborative learning at the workplace. In the context of an international research project we have taken motivational aspects into account during the design phase and started a participatory process involving researchers, end-users, managers, designers and developers. As initial findings show, a continuous dialogue with end-users may contribute to creating a sense of ownership amongst them and become a motivational driver for the future use of the system.

    2014-01-01

    Providing a critical view on user participation in design, disentangling decision making and power in design, this book uses fieldwork material from two large participatory design projects: one experimental in the field of urban planning, the other a product development project within health care. Addressing power issues in participatory design is critical to providing a realistic view of the possibilities and limitations of participation. Design is decision-making: during a design process a huge number of decisions?taken before the designers end up with a design result - an artefact or system

  18. A case study in the participatory design of a collaborative science-based learning environment

    Science.gov (United States)

    Chin, George, Jr.

    Educational technology research studies have found computer and software technologies to be underutilized in U.S. classrooms. In general, many teachers have had difficulty integrating computer and software technologies into learning activities and classroom curriculums because specific technologies are ill-suited to their needs, or they lack the ability to make effective use of these technologies. In the development of commercial and business applications, participatory design approaches have been applied to facilitate the direct participation of users in system analysis and design. Among the benefits of participatory design include mutual learning between users and developers, envisionment of software products and their use contexts, empowerment of users in analysis and design, grounding of design in the practices of users, and growth of users as designers and champions of technology. In the context of educational technology development, these similar consequences of participatory design may lead to more appropriate and effective education systems as well as greater capacities by teachers to apply and integrate educational systems into their teaching and classroom practices. We present a case study of a participatory design project that took place over a period of two and one half years, and in which teachers and developers engaged in the participatory analysis and design of a collaborative science learning environment. A significant aspect of the project was the development methodology we followed---Progressive Design. Progressive Design evolved as an integration of methods for participatory design, ethnography, and scenario-based design. In this dissertation, we describe the Progressive Design approach, how it was used, and its specific impacts and effects on the development of educational systems and the social and cognitive growth of teachers.

  2. Designers' and users' roles in participatory design: What is actually co-designed by participants?

    Science.gov (United States)

    Barcellini, Flore; Prost, Lorène; Cerf, Marianne

    2015-09-01

    This research deals with an analysis of forms of participation in a participatory design (PD) process of a software that assesses the sustainability of agricultural cropping systems. We explore the actual forms of participation of designers and users by adapting an Actual Role Analysis in Design approach (Barcellini et al., 2013) to capture the levels of abstraction (conceptual, functional and operational) of participants' discussions. We show that: (1) the process does not only concern the design of the artifact itself, but also the design of the concept of sustainability; (2) all participants (users & designers) have a role in co-designing the concept (in our case, sustainability); (3) some roles and profiles are key to this co-design. We discuss our contributions to both the research and the practices of participatory design. These contributions deal with the production of a method and related knowledge about actual activities in participatory design situations. They may support the development of relevant training programs regarding participatory situations, or be reflexive activities that can help those who are involved in designing and leading in participatory situations, to make improvements.

    Historically, Participatory Design (PD) was introduced and applied in the Scandinavian and American context as a practical design method for collective creativity and stakeholder involvement. In this paper, by fusing game elements into PD, we suggest a first step towards a culturally independent PD...... method called the ICT Service Design Game to ease the prevailing concern that PD has limited applicability in other cultural settings. We conduct four experiments on ICT Service Design Game in Scandinavia and Asia to evaluate its feasibility. The experiments identify some differences in the PD process...... and the created Persona characteristics, probably due to cultural differences. Of more interestingly, despite these process differences, the game elements of our PD variant were found to promote the key values of PD in culturally diverse settings by stimulating idea creation and participation. Our experiments...

    Full Text Available The design of the mobility enhancement robotic wheelchair (MEBot was based on input from electric powered wheelchair (EPW users regarding the conditions they encounter when driving in both indoor and outdoor environments that may affect their safety and result in them becoming immobilized, tipping over, or falling out of their wheelchair. Phase I involved conducting a participatory design study to understand the conditions and barriers EPW users found to be difficult to drive in/over. Phase II consisted of creating a computer-aided design (CAD prototype EPW to provide indoor and outdoor mobility that addressed these conditions with advanced applications. Phase III involved demonstrating the advanced applications and gathering feedback from end users about the likelihood they would use the advanced applications. The CAD prototype incorporated advanced applications, including self-leveling, curb climbing, and traction control, that addressed the challenging conditions and barriers discussed with EPW users (n = 31 during the participatory design study. Feedback on the CAD design and applications in phase III from end users (n = 12 showed a majority would use self-leveling (83%, traction control (83%, and curb climbing (75%. The overall design of MEBot received positive feedback from EPW users. However, these opinions will need to be reevaluated through user trials as the design advances.

  16. Playful Collaborative Exploration: New Research Practice in Participatory Design

    Directory of Open Access Journals (Sweden)

    Martin Johansson

    2005-01-01

    Full Text Available Within the Participatory Design community as well as the Computer Supported Cooperative Work tradition, a lot of effort has been put into the question of letting field studies inform design. In this paper, we describe how game-like approaches can be used as a way of exploring a practice from a design point of view. Thinking of ethnographic fieldwork as a base for sketching, rather than descriptions, creates openness that invites collaborative authoring. The concept of playful collaborative exploration suggests certain ways of interacting with material from field studies so that it becomes a design material for an open-ended design process. We have carried out field studies, transformed the field material into design material, and set up a design game for working with it together with the people we followed in the field. The design game builds on an idea about the power of narratives and the benefits of constraining rules. We believe that this framework for collaboration opens for playfulness, experimentation, and new design ideas.

  17. Applied Ethnobotany: Participatory Approach for Community Development and Conservation

    Institute of Scientific and Technical Information of China (English)

    2002-01-01

    Applied ethnobotany is a nev subject in ethnobiological sciences referring to the transferring, reviving and cultivating ethnobotanical knowledge among different social groups within intra-and-inter-communities. Much research related to biodiversity in many countries is largely devoted to the gathering of more academic information, rather than to more incise studies focusing on finding answers to pressing challenges related to the use of plants by communities. China is a country possessing rich biodiversity and cultural diversity. The long history of Chinese traditional medicine, diversity of cultivated crops and utilization of wild plant species are great cultural traditions to the country. Today, many societies of the country are still intricately linked to the natural environment economically as well as societies and groups within China. However, China is facing major changes in modernization of the country's economy, and globalization to form part of the world exchange system. Increasingly high levels of consumptions of natural plants, as well as national and international trades on plant products have resulted, space in over-harvesting of wild resources and accelerated environmental degradation. Local social structures and cultural traditions have also changed in order to cope with policy changes. In this background, over the last decade, applied ethnobotany for rural community development and conservation has been employed in different field projects and ethnic minority communities in Yunnan province of China. The applied ethnobotany has focused on work at community level to achieve sustainable use of natural resources and conservation. This presentation discusses findings and lessons learned from the projects on alternatives and innovations to shifting cultivation in Xishuangbanna, southwestern China.

    Mahmoud, Magdi S

    2012-01-01

    Applied Control System Design examines several methods for building up systems models based on real experimental data from typical industrial processes and incorporating system identification techniques. The text takes a comparative approach to the models derived in this way judging their suitability for use in different systems and under different operational circumstances. A broad spectrum of control methods including various forms of filtering, feedback and feedforward control is applied to the models and the guidelines derived from the closed-loop responses are then composed into a concrete self-tested recipe to serve as a check-list for industrial engineers or control designers. System identification and control design are given equal weight in model derivation and testing to reflect their equality of importance in the proper design and optimization of high-performance control systems. Readers’ assimilation of the material discussed is assisted by the provision of problems and examples. Most of these e...

    2015-03-01

    Full Text Available This study used observation and interviews with participants in “PunCar Action” to understand how participatory design methods can be applied to the education of rural individuals in information and communication technology (ICT. PunCar Action is a volunteer program in which ICT educators tour the rural communities of Taiwan, offering courses on the use of digital technology. This paper makes three contributions: First, we found that participatory design is an excellent way to teach ICT and Web 2.0 skills, co-create community blogs, and sustain intrinsic motivation to use Web applications. Second, PunCar Action provides an innovative bottom-up intergenerational ICT education model with high penetrability capable of enhancing the confidence of rural residents in the use of ICT. Third, the content of basic courses was based on applications capable of making the lives of elderly individuals more convenient, and the advanced course was based on the co-creation of community blogs aimed at reviving the core functions of communities and expanding local industry. Our research was conducted with the use of a non-quantitative index to measure ICT learning performance of participants from a rural community. The results show that PunCar Action emphasizes interpersonal communication and informational applications and creates a collaborative process that encourages rural residents to take action to close the digital divide.

    Disrespect and abuse (D&A) during facility-based childbirth is a topic of growing concern and attention globally. Several recent studies have sought to quantify the prevalence of D&A, however little evidence exists about effective interventions to mitigate disrespect and abuse, and promote respectful maternity care. In an accompanying article, we describe the process of selecting, implementing, and evaluating a package of interventions designed to prevent and reduce disrespect and abuse in a large urban hospital in Tanzania. Though that study was not powered to detect a definitive impact on reducing D&A, the results showed important changes in intermediate outcomes associated with this goal. In this commentary, we describe the factors that enabled this effect, especially the participatory approach we adopted to engage key stakeholders throughout the planning and implementation of the program. Based on our experience and findings, we conclude that a visible, sustained, and participatory intervention process; committed facility leadership; management support; and staff engagement throughout the project contributed to a marked change in the culture of the hospital to one that values and promotes respectful maternity care. For these changes to translate into dignified care during childbirth for all women in a sustainable fashion, institutional commitment to providing the necessary resources and staff will be needed.

  15. User-centric incentive design for participatory mobile phone sensing

    Science.gov (United States)

    Gao, Wei; Lu, Haoyang

    2014-05-01

    Mobile phone sensing is a critical underpinning of pervasive mobile computing, and is one of the key factors for improving people's quality of life in modern society via collective utilization of the on-board sensing capabilities of people's smartphones. The increasing demands for sensing services and ambient awareness in mobile environments highlight the necessity of active participation of individual mobile users in sensing tasks. User incentives for such participation have been continuously offered from an application-centric perspective, i.e., as payments from the sensing server, to compensate users' sensing costs. These payments, however, are manipulated to maximize the benefits of the sensing server, ignoring the runtime flexibility and benefits of participating users. This paper presents a novel framework of user-centric incentive design, and develops a universal sensing platform which translates heterogenous sensing tasks to a generic sensing plan specifying the task-independent requirements of sensing performance. We use this sensing plan as input to reduce three categories of sensing costs, which together cover the possible sources hindering users' participation in sensing.

    Participatory design (PD) methods are currently of little use in the textile industry, even though the need for multiple stakeholder involvement in the industry is growing. In this paper, we argue that PD represents a potential for innovation in the textile industry, due to PD’s collaborative...... nature facilitating dialogue between different stakeholders and its ability to move stakeholder participation to the early stages of the design process. We have explored PD tools in a design process engaging architects and textile designers in designing textile products for Danish hospitals.

    BeLue, Rhonda; Carmack, Chakema; Myers, Kyle R; Weinreb-Welch, Laurie; Lengerich, Eugene J

    2012-12-01

    Community-based participatory research (CBPR) is being used increasingly to address health disparities and complex health issues. The authors propose that CBPR can benefit from a systems science framework to represent the complex and dynamic characteristics of a community and identify intervention points and potential "tipping points." Systems science refers to a field of study that posits a holistic framework that is focused on component parts of a system in the context of relationships with each other and with other systems. Systems thinking tools can assist in intervention planning by allowing all CBPR stakeholders to visualize how community factors are interrelated and by potentially identifying the most salient intervention points. To demonstrate the potential utility of systems science tools in CBPR, the authors show the use of causal loop diagrams by a community coalition engaged in CBPR activities regarding youth drinking reduction and prevention.

    2014-01-01

    Restricted mobility is the most common impairment among older adults and a manual wheelchair is often prescribed to address these limitations. However, limited access to rehabilitation services results in older adults typically receiving little or no mobility training when they receive a wheelchair. As an alternative and novel approach, we developed a therapist-monitored wheelchair skills home training program delivered via a computer tablet. To optimize efficacy and adherence, principles of self-efficacy and adult learning theory were foundational in the program design. A participatory action design approach was used to engage older adult wheelchair users, care providers, and prescribing clinicians in an iterative design and development process. A series of prototypes were fabricated and revised, based on feedback from eight stakeholder focus groups, until a final version was ready for evaluation in a clinical trial. Stakeholder contributions affirmed and enhanced the foundational theoretical principles and provided validation of the final product for the target population. PMID:25276768

    balancing power dynamics between participants; and the provision of information and decision-making power to all participants. Participatory processes initiated or facilitated by government bodies led to significantly less trust, information gain, learning, and flexible solutions. However, in these processes, decisions were more acceptable to and likely to be implemented by governments and by those who had to apply them on the ground. These findings provide a solid empirical basis for best practice in the design of participatory processes in SLM in a number of contexts internationally, which if followed, increase the likelihood of providing beneficial environmental and social outcomes for those involved.

  3. Participatory design in lean production: which contribution from employees? For what end?

    Science.gov (United States)

    Perez Toralla, M S; Falzon, P; Morais, A

    2012-01-01

    The proponents of lean production have pointed to the positive effects of the work organization on employees in terms of autonomy, enhanced skills and empowerment mainly by their participation into the continuous improvement of work process. But studies that have examined this issue suggest that the increase in autonomy is not sufficient to compensate for increases work intensity. Participatory design has grown extensively in manufacturing since the 1980's under the impulsion of the Scandinavian socio-technical system approach and it's central in the model of lean production performance. Its main objectives are to improve quality, increase productivity and safety through employee's participation to the reduction of non-value added activities, such as defined by lean production. In the line of the studies on participatory design and continuous improvement the present study examines the functioning of work groups, based on the kaizen model, the aim of which was to improve the proportion of "value-added activities" and working conditions, essentially physical constraints. The main results are consistent with the literature and show that accelerated forms of re-conception activities give employees limited room for maneuver to elaborate solutions based on the analysis of the real activity. This study is part of a broader initiative that goes in the direction of continuous improvement of the design process itself so that it integrates the real constraints of work and propose changes bases on work as it actually takes place, beyond pre-established performance goals bases on the reduction of "non added value activities".

  7. Design Charrette as Methodology for Post-Disaster Participatory Reconstruction: Observations from a Case Study in Fukushima, Japan

    Directory of Open Access Journals (Sweden)

    Hui Zhang

    2015-05-01

    Full Text Available Although there has been a growing body of literature on post-disaster participatory reconstruction, a shared understanding on a participatory approach is insufficient. A design charrette is a participatory planning that is particularly suitable for situations in which multidisciplinary professionals and non-professional stakeholders collaborate to accomplish target tasks in a short period of time. The purpose of this paper is to explore the role of design charrette as a methodology in the context of post-disaster reconstruction in Japan. This will be achieved through a participatory observation on a design charrette in Minamisoma City, Japan, after the Fukushima accident. The charrette includes the participation of multiple stakeholders in intercultural, intergenerational and interdisciplinary exchanges. The contributions and constraints of the charrette are analyzed on the basis of the authors’ observation, and a strategy to improve post-disaster reconstruction charrette is thereby proposed. This study shows that the charrette is a useful method for communication and collaboration in the post-disaster context. Furthermore, it also demonstrates that assuring the participation of all key stakeholders, improving the training of participants and introducing resource analysis during the charrette’s preparatory stage are the essential conditions for the legitimacy and policy compliance of the final result.

    The critical design method aims to discuss ways of opening up the (design) brief when planning, designing, building, operating and maintaining the future of the built environment - public as well as private, indoor as well as outdoor. Focusing on "designials" (fundamental forms of design being), the methodology intends to illustrate the fact that objects; including buildings, parks, transportation systems, etc. may directly encroach upon certain "existentials" (fundamental forms of human being) - thus shed light on how a design process is normally conducted, and furthermore, how that affects people's existential well-being.

    Background Serious digital games can be effective at changing healthy lifestyles, but large differences in their effectiveness exist. The extent of user involvement in game design may contribute to game effectiveness by creating a better fit with user preferences. Participatory design (PD), which represents active user involvement as informant (ie, users are asked for input and feedback) or codesigner (ie, users as equal partners in the design) early on and throughout the game development, may be associated with higher game effectiveness, as opposed to no user involvement or limited user involvement. Objective This paper reports the results of a meta-analysis examining the moderating role of PD in the effectiveness of serious digital games for healthy lifestyle promotion. Methods Four databases were searched for peer-reviewed papers in English that were published or in press before October 2014, using a (group-) randomized controlled trial design. Effectiveness data were derived from another meta-analysis assessing the role of behavior change techniques and game features in serious game effectiveness. Results A total of 58 games evaluated in 61 studies were included. As previously reported, serious digital games had positive effects on healthy lifestyles and their determinants. Unexpectedly, PD (g=0.075, 95% CI 0.017 to 0.133) throughout game development was related to lower game effectiveness on behavior (Q=6.74, PGames developed with PD (g=0.171, 95% CI 0.061 to 0.281, Pgame effectiveness on self-efficacy (Q=7.83, Pgame design (g=0.384, 95% CI 0.283 to 0.485, Pgame design element. Games developed with PD were more effective in changing behavioral determinants when they included users in design elements on game dynamics (beta=.215, 95% CI .075 to .356, Pgame levels was also related to higher game effectiveness (Q=7.02, Peffectiveness when used to create the game challenge (Q=11.23, Pgame effectiveness when used to create characters (Q=4.36, Pgame world (Q=3

I try to research the theory of space production from Lefebvre and dialectical utopia from David Harvey while explaining the relationship among environment contamination, production expansion and globalisation. In this process, as Foucault said, " the 'fascism that reigns in our heads' is far more insidious than anything that gets constructed outside". Thus, I analyse economic development approach in this day and age and study how to apply participatory strategy to construct an appropriate living space and how to apply this principle to improve urban environmental quality.

  16. A Concept for Testing Decision Support Tools in Participatory Processes Applied to the ToSIA Tool

    Directory of Open Access Journals (Sweden)

    David Edwards

    2013-04-01

    Full Text Available ToSIA (Tool for Sustainability Impact Assessment offers a transparent and consistent methodological framework to assess impacts of changes (technological, policy, management, etc. in the forest-based sector. This tool is able to facilitate the decision making process within and between diverse groups of stakeholders (e.g., forest managers and policymakers as it provides a neutral, transparent and data-driven platform for stakeholder interaction and communication. To test these capabilities of ToSIA, a practical approach to test if a decision support system is suitable for participatory processes was developed based on a set of evaluation criteria for participatory processes. ToSIA’s performance was assessed and discussed in different categories against a selection of criteria for successful participatory processes: six criteria were fulfilled by ToSIA, in nine, ToSIA is potentially helpful, in two, criteria ToSIA has no influence, and for three criteria, no experiences exist until now. As a result, ToSIA’s conceptual suitability as a participatory decision support system was confirmed for two interlinked roles: as a decision support system to assess alternative scenarios, and as a communication platform for stakeholder interaction.

    Full Text Available Abstract Background Organizations that collect substantial data for decision-making purposes are often characterized as being 'data rich' but 'information poor'. Maps and mapping tools can be very useful for research transfer in converting locally collected data into information. Challenges involved in incorporating GIS applications into the decision-making process within the non-profit (public health sector include a lack of financial resources for software acquisition and training for non-specialists to use such tools. This on-going project has two primary phases. This paper critically reflects on Phase 1: the participatory design (PD process of developing a collaborative web-based GIS tool. Methods A case study design is being used whereby the case is defined as the data analyst and manager dyad (a two person team in selected Ontario Early Year Centres (OEYCs. Multiple cases are used to support the reliability of findings. With nine producer/user pair participants, the goal in Phase 1 was to identify barriers to map production, and through the participatory design process, develop a web-based GIS tool suited for data analysts and their managers. This study has been guided by the Ottawa Model of Research Use (OMRU conceptual framework. Results Due to wide variations in OEYC structures, only some data analysts used mapping software and there was no consistency or standardization in the software being used. Consequently, very little sharing of maps and data occurred among data analysts. Using PD, this project developed a web-based mapping tool (EYEMAP that was easy to use, protected proprietary data, and permit limited and controlled sharing between participants. By providing data analysts with training on its use, the project also ensured that data analysts would not break cartographic conventions (e.g. using a chloropleth map for count data. Interoperability was built into the web-based solution; that is, EYEMAP can read many different

    The implementation of regular and relevant evaluations of surveillance systems is critical in improving their effectiveness and their relevance whilst limiting their cost. The complex nature of these systems and the variable contexts in which they are implemented call for the development of flexible evaluation tools. Within this scope, participatory tools have been developed and implemented for the African swine fever (ASF) surveillance system in Corsica (France). The objectives of this pilot study were, firstly, to assess the applicability of participatory approaches within a developed environment involving various stakeholders and, secondly, to define and test methods developed to assess evaluation attributes. Two evaluation attributes were targeted: the acceptability of the surveillance system and its the non-monetary benefits. Individual semi-structured interviews and focus groups were implemented with representatives from every level of the system. Diagramming and scoring tools were used to assess the different elements that compose the definition of acceptability. A contingent valuation method, associated with proportional piling, was used to assess the non-monetary benefits, i.e., the value of sanitary information. Sixteen stakeholders were involved in the process, through 3 focus groups and 8 individual semi-structured interviews. Stakeholders were selected according to their role in the system and to their availability. Results highlighted a moderate acceptability of the system for farmers and hunters and a high acceptability for other representatives (e.g., private veterinarians, local laboratories). Out of the 5 farmers involved in assessing the non-monetary benefits, 3 were interested in sanitary information on ASF. The data collected via participatory approaches enable relevant recommendations to be made, based on the Corsican context, to improve the current surveillance system. PMID:26489602

    2015-02-01

    Full Text Available The livelihoods of people in the Andes are expected to be affected by climate change due to their dependence on glacier water. The observed decrease in glacier volume over the last few decades is likely to accelerate during the current century, which will affect water availability in the region. This paper presents an approach for participatory development of community-based adaptation measures to cope with the projected impacts of climate change. It combines in an innovative manner participatory design with physical measurements, modeling and a vulnerability analysis. Vulnerability to drought is made operational for households in a catchment of the Ocoña River basin in Peru. On the basis of a household survey (n = 94 we explore how a vulnerability index (risk divided by response efficacy can be used to assess the distribution of vulnerability over households, and how socio-economic factors determine this vulnerability. Water entitlement, area of irrigated land, income and education are all significantly correlated with vulnerability to drought. The research showed that the main source of spring water is local rainwater, and that water use efficiency is low. The selected adaptation measures aimed to increase water availability close to farmland, and increase water use efficiency of farmers and households.

    The model of learning adopted within this paper is the 'spreading ripples' (SR) model proposed by Race (1994). This model was chosen for two important reasons. First, it makes use of accessible ideas and language, .and is therefore simple. Second, .Race suggests that the model can be used in the design, of educational and training programmes (and can thereby be applied to the design of computer-based learning materials).DOI:10.1080/0968776960040303

    Full Text Available Abstract Background With rates of childhood obesity increasing, physical activity (PA promotion especially in young children has assumed greater importance. Given the limited effectiveness of most interventions to date, new approaches are needed. The General Systems theory suggests that involving parents as intervention targets may be effective in fostering healthier life styles in children. We describe the development of a parent-focused participatory intervention and the procedures used to evaluate its effectiveness in increasing daily PA in preschoolers. Methods/Design Thirty-seven South German preschools were identified for this study and agreed to participate. Using a two-armed, controlled cluster-randomized trial design we test a participatory intervention with parents as the primary target group and potential agents of behavioural change. Specifically, the intervention is designed to engage parents in the development, refinement and selection of project ideas to promote PA and in incorporating these ideas into daily routines within the preschool community, consisting of children, teachers and parents. Our study is embedded within an existing state-sponsored programme providing structured gym lessons to preschool children. Thus, child-based PA outcomes from the study arm with the parent-focused intervention and the state-sponsored programme are compared with those from the study arm with the state-sponsored programme alone. The evaluation entails baseline measurements of study outcomes as well as follow-up measurements at 6 and 12 months. Accelerometry measures PA intensity over a period of six days, with the mean over six days used as the primary outcome measure. Secondary outcomes include childrens' BMI, a sum of averaged skin fold thickness measurements across multiple sites, and PA behaviour. Longitudinal multilevel models are used to assess within-subject change and between-group differences in study outcomes, adjusted for covariates

    The wide-scale roll-out of artemisinin combination therapies (ACTs) for the treatment of malaria should be accompanied by continued surveillance of their safety. Post-marketing pharmacovigilance (PV) relies on adverse event (AE) reporting by clinicians, but as a large proportion of treatments are provided by non-clinicians in low-resource settings, the effectiveness of such PV systems is limited. To facilitate reporting, AE forms should be easily completed; however, most are challenging for lower-level health workers and non-clinicians to complete. Through participatory research, we sought to develop user-friendly AE report forms to capture information on events associated with ACTs.Following situation analysis, we undertook workshops with community medicine distributors and health workers in Jinja, Uganda, to develop a reporting form based on experiences and needs of users, and communication and visual perception principles. Participants gave feedback for revisions of subsequent versions. We then conducted 8 pretesting sessions with 77 potential end users to test and refine passive and active versions of the form.The development process resulted in a form that included a pictorial storyboard to communicate the rationale for the information needed and facilitate rapport between the reporter and the respondent, and a diary format to record the drug administration and event details in chronological relation to each other. Successive rounds of pretesting used qualitative and quantitative feedback to refine the form, with the final round showing over 80% of the form completed correctly by potential end users.We developed novel AE report forms that can be used by non-clinicians to capture pharmacovigilance data for anti-malarial drugs. The participatory approach was effective for developing forms that are intuitive for reporters, and motivating for respondents. The forms, or their key components, could be adapted for use in other low-literacy settings to improve quality

  10. Participatory Privacy: Enabling Privacy in Participatory Sensing

    CERN Document Server

    De Cristofaro, Emiliano

    2012-01-01

    Participatory Sensing is an emerging computing paradigm that enables the distributed collection of data by self-selected participants. It allows the increasing number of mobile phone users to share local knowledge acquired by their sensor-equipped devices, e.g., to monitor temperature, pollution level or consumer pricing information. While research initiatives and prototypes proliferate, their real-world impact is often bounded to comprehensive user participation. If users have no incentive, or feel that their privacy might be endangered, it is likely that they will not participate. In this article, we focus on privacy protection in Participatory Sensing and introduce a suitable privacy-enhanced infrastructure. First, we provide a set of definitions of privacy requirements for both data producers (i.e., users providing sensed information) and consumers (i.e., applications accessing the data). Then, we propose an efficient solution designed for mobile phone users, which incurs very low overhead. Finally, we di...

    The livelihoods of people in the Andes are expected to be affected by climate change due to their dependence on glacier meltwater during the growing season. The observed decrease in glacier volume over the last few decades is likely to accelerate during the current century, which will affect water availability in the region. This paper presents the implementation of an approach for the participatory development of community-based adaptation measures to cope with the projected impacts of climate change, which was implemented jointly by the local community and by a team consisting of an NGO, Peruvian ministry of environment, research organisations and a private sector organisation. It bases participatory design on physical measurements, modelling and a vulnerability analysis. Vulnerability to drought is made operational for households in a catchment of the Ocoña river basin in Peru. On the basis of a household survey we explore how a vulnerability index (impacts divided by the households' perceived adaptive capacity) can be used to assess the distribution of vulnerability over households in a sub catchment. The socio-economic factors water entitlement, area of irrigated land, income and education are all significantly correlate with this vulnerability to drought. The index proved to be appropriate for communicating about vulnerability to climate change and its determining factors with different stakeholders. The water system research showed that the main source of spring water is local rainwater, and that water use efficiency in farming is low. The adaptation measures that were jointly selected by the communities and the project team aimed to increase water availability close to farmland, and increase water use efficiency, and these will help to reduce the communities vulnerability to drought.

    Encoders are generally used to track the motion of industrial mechanisms. However, the information obtained by encoders may have errors due to encoder aging or mechanism-design problem. Therefore, information by visual feedback is a better way to track the movement of industrial mechanisms. However, image information costs lots of computing effort so it is not easy to be used in real-time control applications. This manuscript derives a simple but effective visual feedback method to follow the target and the image information is obtained only by a general handy camcorder. Besides, the proposed method can track multi-locations in a meantime. Fast image pattern recognition and localisation of the colour histogram by using a moving tracking block is applied to increase the calculation speed. Finally, the obtained locations information by the proposed visual feedback method is applied in an industrial crane control system to verify the effectiveness.

  15. Participatory telerobotics

    Wissner-Gross, Alexander D.; Sullivan, Timothy M.

    2013-05-01

    We present a novel "participatory telerobotics" system that generalizes the existing concept of participatory sensing to include real-time teleoperation and telepresence by treating humans with mobile devices as ad-hoc telerobots. In our approach, operators or analysts first choose a desired location for remote surveillance or activity from a live geographic map and are then automatically connected via a coordination server to the nearest available trusted human. That human's device is then activated and begins recording and streaming back to the operator a live audiovisual feed for telepresence, while allowing the operator in turn to request complex teleoperative motions or actions from the human. Supported action requests currently include walking, running, leaning, and turning, all with controllable magnitudes and directions. Compliance with requests is automatically measured and scored in real time by fusing information received from the device's onboard sensors, including its accelerometers, gyroscope, magnetometer, GPS receiver, and cameras. Streams of action requests are visually presented by each device to its human in the form of an augmented reality game that rewards prompt physical compliance while remaining tolerant of network latency. Because of its ability to interactively elicit physical knowledge and operations through ad-hoc collaboration, we anticipate that our participatory telerobotics system will have immediate applications in the intelligence, retail, healthcare, security, and travel industries.

    This paper describes a series of student projects which are intended to complement theoretical education in acoustics and engineering noise control with practical experience. The projects are also intended to enhance the students' ability to work in a team, to manage a project, and to present their results. The projects are carried out in close cooperation with industrial partners so that the students can get a taste of the professional life of noise control engineers. The organization of such a project, its execution, and some of the results from the most recent student project are presented as a demonstrative example. This latest project involved the creation of noise maps of a production hall, the acoustic analysis of a packaging machine, and the acoustic analysis of a spiral vibratory conveyor. Upon completion of the analysis, students then designed, applied, and verified some simple preliminary noise reduction measures to demonstrate the potential of these techniques. PMID:22423803

    It is only the observable part of the real world that can be stored in data.For such incomplete and ill-structured data,data crystallizing aims at presenting the hidden structure among events including unobservable events.This is realized by data crystallization,where dummy items,corresponding to potential existence ofunobservable events,are inserted to the given data.These dummy items and their relations with observable events are visualized by applying KeyGraph to the data with dummy items,like the crystallization of snow where dusts are involved in the formation of crystallization of water molecules.For tuning the granularity level of structure to be visualized,the tool of data crystallization is integrated with human's process of understanding significant scenarios in the real world.This basic method is expected to be applicable for various real world domains where previous methods of chance-discovery lead human to successful decision making.In this paper,we apply the data crystallization with human-interactive annealing (DCHA) to the design of products in a real company.The results show its effect to industrial decision making.

This tool aims to provide education and awareness regarding the management of symptoms and stroke risk associated with AF, while engaging patients to identify if their condition is optimally managed and to become involved in their own care. An interdisciplinary group of health care providers and designers worked together in a participatory design approach to develop the tool with input from patients. Usability testing was completed with 22 patients of varying demographics to represent the characteristics of the patient population. The findings from usability testing interviews were used to further improve and develop the tool to improve ease of use. A physician-facing tool was also developed to help to explain the tool and provide a brief summary of the 2012 Canadian Cardiovascular Society atrial fibrillation guidelines. By incorporating patient input and human-centered design with the knowledge, experience, and medical expertise of health care providers, we have used an approach in developing the tool that tries to more effectively meet patients' needs.

    2016-06-01

    Full Text Available Although the design of participatory processes to manage social-ecological systems needs to be adapted to local contexts, it is unclear which elements of process design might be universal. We use empirical evidence to analyze the extent to which context and process design can enable or impede stakeholder participation and facilitate beneficial environmental and social outcomes. To explore the role of design and minor variations in local context on the outcomes of participatory processes, we interviewed participants and facilitators from 11 case studies in which different process designs were used to select sustainable land management options in Spain and Portugal. We analyzed interview data using quantitative and qualitative approaches. Results showed that although some aspects of local context affected process outcomes, factors associated with process design were more significant. Processes leading to more beneficial environmental and social outcomes included the following: the legitimate representation of stakeholders; professional facilitation including structured methods for aggregating information and balancing power dynamics among participants; and provision of information and decision-making power to all participants. Although processes initiated or facilitated by government bodies led to significantly less trust, information gain, and learning, decisions in these processes were more likely to be accepted and implemented. To further test the role of context in determining the outcomes of participation, we interviewed facilitators from a process that was replicated across 13 dryland study sites around the world, reflecting much greater national variations in context. The similarity of outcomes across these sites suggested that the socio-cultural context in which the process was replicated had little impact on its outcomes, as long as certain design principles were fulfilled. Overall, our findings provide a solid empirical basis for good

    Full Text Available Concepts of Human Computer Interaction have crossed disciplinary boundaries allowing the discovery of underlying stakeholder affordances to emerge during the design research phase of system design. For the current scenario, middle school mathematics teachers as data-driven decision makers are inundated with diagnostic and assessment data, resulting in data deluge. The situation is unlikely to subside as digital technologies and media are broadly adopted for instruction and learning. Teachers could benefit from tools to quickly sift through this data to inform classroom instruction. Data should be visualized in a way that teachers can make real-time formative and summative assessments of student progress. The purpose of this article is to introduce a mixed-method mode of discovery to uncover affordances innate to classroom teachers during the design of an iPad data visualization application. These technology-assisted “dashboard” platforms could serve as efficient and effective interventions to deal with the copious amounts of data streams now available to teachers.

  17. Radiation chemistry applied to drug design

    International Nuclear Information System (INIS)

    Radiation chemistry can contribute to drug design by quantifying redox properties of drugs and where free radicals are suspected intermediates in drug action, radiation can be used to generate these putative species and help characterise relevant reactions. Steady radiolysis produces radicals at a readily-varied but quantified rate; pulse radiolysis with fast spectrophotometric and/or conductimetric detection enables the kinetic properties of radicals to be monitored directly. Using these methods, radical intermediates from drugs with specific cytotoxicity towards hypoxic cells have been shown to react rapidly with oxygen. Radical oxidants from activated neutrophils include superoxide and hydroxyl radicals, and radiation-chemical methods have an important role to play in rational drug design to exploit such oxidative chemistry. Antioxidants can also be evaluated quantitatively by radiolysis methods; the conjugation reactions of thiyl radicals with thiolate and oxygen are now recognised to be major contributions of pulse radiolysis to thiol biochemistry.

Steady radiolysis produces radicals at a readily-varied but quantified rate; pulse radiolysis with fast spectrophotometric and/or conductimetric detection enables the kinetic properties of radicals to be monitored directly. Using these methods, radical intermediates from drugs with specific cytotoxicity towards hypoxic cells have been shown to react rapidly with oxygen. Radical oxidants from activated neutrophils include superoxide and hydroxyl radicals, and radiation-chemical methods have an important role to play in rational drug design to exploit such oxidative chemistry. Antioxidants can also be evaluated quantitatively by radiolysis methods; the conjugation reactions of thiyl radicals with thiolate and oxygen are now recognised to be major contributions of pulse radiolysis to thiol biochemistry.

  20. Digital publics and participatory education

    2010-10-01

    Full Text Available This article—a collaborative exploration between instructors, students, and members of the broader, digital classroom community—explores how the strategic incorporation of sociotechnical networks and digital technologies facilitates literate practices that extend the classroom in productive ways. The article builds toward coauthors’ reflective practices (Schön, 1983, or “participatory perspectives”, had during an undergraduate English Studies course at a mid-sized, public, American university. Specifically, participants argue that these literate practices afforded not just information sharing, but the opening up of a traditional classroom to include broader digital publics and collaborative knowledge work (Spinuzzi, 2006. Toward this end, we ground literate practice in scholarship that attends to public writing in online spaces, and theoretically frame our argument using Jenkins et al.’s (2006 principles of participatory education. We then detail the specific curricular approach deliberately designed to create digitally connected publics and end with generalizable significance of coauthors’ participatory perspectives.

    Background Dengue virus (and Chikungunya and Zika viruses) is transmitted by Aedes aegypti and Aedes albopictus mosquitoes and causes considerable human morbidity and mortality. As there is currently no vaccine or chemoprophylaxis to protect people from dengue virus infection, vector control is the only viable option for disease prevention. The purpose of this paper is to illustrate the design and placement process for an attractive lethal ovitrap to reduce vector populations and to describe lessons learned in the development of the trap. Methods This study was conducted in 2010 in Iquitos, Peru and Lopburi Province, Thailand and used an iterative community-based participatory approach to adjust design specifications of the trap, based on community members’ perceptions and feedback, entomological findings in the lab, and design and research team observations. Multiple focus group discussions (FGD) were held over a 6 month period, stratified by age, sex and motherhood status, to inform the design process. Trap testing transitioned from the lab to within households. Results Through an iterative process of working with specifications from the research team, findings from the laboratory testing, and feedback from FGD, the design team narrowed trap design options from 22 to 6. Comments from the FGD centered on safety for children and pets interacting with traps, durability, maintenance issues, and aesthetics. Testing in the laboratory involved releasing groups of 50 gravid Ae. aegypti in walk-in rooms and assessing what percentage were caught in traps of different colors, with different trap cover sizes, and placed under lighter or darker locations. Two final trap models were mocked up and tested in homes for a week; one model was the top choice in both Iquitos and Lopburi. Discussion The community-based participatory process was essential for the development of novel traps that provided effective vector control, but also met the needs and concerns of community

    We present the collaborative development of a web-based data collection and monitoring plan for thirty-two county councils within New Mexico's health council system. The monitoring plan, a key component in our multiyear participatory statewide evaluation process, was co-developed with the end users: representatives of the health councils. Guided by the Institute of Medicine's Community, Health Improvement Process framework, we first developed a logic model that delineated processes and intermediate systems-level outcomes in council development, planning, and community action. Through the online system, health councils reported data on intermediate outcomes, including policy changes and funds leveraged. The system captured data that were common across the health council system, yet was also flexible so that councils could report their unique accomplishments at the county level. A main benefit of the online system was that it provided the ability to assess intermediate, outcomes across the health council system. Developing the system was not without challenges, including creating processes to ensure participation across a large rural state; creating shared understanding of intermediate outcomes and indicators; and overcoming technological issues. Even through the challenges, however, the benefits of committing to using participatory processes far outweighed the challenges. PMID:24184843

Efficiency of the proposed approach is demonstrated on example.

  15. The case for integrating grounded theory and participatory action research: empowering clients to inform professional practice.

    Science.gov (United States)

    Teram, Eli; Schachter, Candice L; Stalker, Carol A

    2005-10-01

    Grounded theory and participatory action research methods are distinct approaches to qualitative inquiry. Although grounded theory has been conceptualized in constructivist terms, it has elements of positivist thinking with an image of neutral search for objective truth through rigorous data collection and analysis. Participatory action research is based on a critique of this image and calls for more inclusive research processes. It questions the possibility of objective social sciences and aspires to engage people actively in all stages of generating knowledge. The authors applied both approaches in a project designed to explore the experiences of female survivors of childhood sexual abuse with physical therapy and subsequently develop a handbook on sensitive practice for clinicians that takes into consideration the needs and perspectives of these clients. Building on this experience, they argue that the integration of grounded theory and participatory action research can empower clients to inform professional practice. PMID:16221884

    A character of fuel cell with high potency and low pollution was known well and considered as a new generation of power technology. In this study a novel design of flow slab addressed and originated from bionic concept will be applied to improve the performance of PEMFC. Simulation results executed at Re = 100 show that the bionic flow type will possess a better uniformity of velocity and lower pressure drop. Besides, the integral performance concerned at SDR and PDR will also show the bionic flow type to be an outstanding design. Hence, this novel flow design addressed will be useful to promotion of PEMFC.

    In this work a comparison of three techniques of optimization is presented applied to the design of the recharge of fuel in reactors of water in boil. In short, the techniques were applied to the design of a recharge of a cycle of balance of 18 months of the Laguna Verde Nucleo electric Central. The used techniques were Genetic Algorithms, Taboo Search and Neural Nets. The conditions to apply the different techniques were the same ones. The comparison of the results quality and the computational resources required to obtain them, it indicates that with the Taboo Search better results are achieved but the computational cost is very big. On the other hand the neural net with low computational cost obtains acceptable results. Additionally to this comparison, in this work a summary of the works that have been carried out for the fuel recharges optimization from the years 60 until the present time is presented. (Author)

    2002-01-01

    Three methods of probabilistic uncertainty propagation and quantification (the method of moments, Monte Carlo simulation, and a nongradient simulation search method) are applied to an aircraft analysis and conceptual design program to demonstrate design under uncertainty. The chosen example problems appear to have discontinuous design spaces and thus these examples pose difficulties for many popular methods of uncertainty propagation and quantification. However, specific implementation features of the first and third methods chosen for use in this study enable successful propagation of small uncertainties through the program. Input uncertainties in two configuration design variables are considered. Uncertainties in aircraft weight are computed. The effects of specifying required levels of constraint satisfaction with specified levels of input uncertainty are also demonstrated. The results show, as expected, that the designs under uncertainty are typically heavier and more conservative than those in which no input uncertainties exist.

    Customization design is a trend for developing a bicycle in recent years. Thus, the comfort of riding a bike is an important factor that should be paid much attention to while developing a bicycle. From the viewpoint of ergonomics, the concept of "fitting object to the human body" is designed into the bicycle frame in this study. Firstly, the important feature points of riding posture were automatically detected by the image processing method. In the measurement process, the best riding posture was identified experimentally, thus the positions of feature points and joint angles of human body were obtained. Afterwards, according to the measurement data, three key points: the handlebar, the saddle and the crank center, were identified and applied to the frame design of various bicycle types. Lastly, this study further proposed a frame size table for common bicycle types, which is helpful for the designer to design a bicycle. PMID:26154206

  9. Experimental designs for autoregressive models applied to industrial maintenance

    International Nuclear Information System (INIS)

    Some time series applications require data which are either expensive or technically difficult to obtain. In such cases scheduling the points in time at which the information should be collected is of paramount importance in order to optimize the resources available. In this paper time series models are studied from a new perspective, consisting in the use of Optimal Experimental Design setup to obtain the best times to take measurements, with the principal aim of saving costs or discarding useless information. The model and the covariance function are expressed in an explicit form to apply the usual techniques of Optimal Experimental Design. Optimal designs for various approaches are computed and their efficiencies are compared. The methods working in an application of industrial maintenance of a critical piece of equipment at a petrochemical plant are shown. This simple model allows explicit calculations in order to show openly the procedure to find the correlation structure, needed for computing the optimal experimental design. In this sense the techniques used in this paper to compute optimal designs may be transferred to other situations following the ideas of the paper, but taking into account the increasing difficulty of the procedure for more complex models. - Highlights: • Optimal experimental design theory is applied to AR models to reduce costs. • The first observation has an important impact on any optimal design. • Either the lack of precision or small starting observations claim for large times. • Reasonable optimal times were obtained relaxing slightly the efficiency. • Optimal designs were computed in a predictive maintenance context

    2013-10-01

    Industrial robots are available in a large variety of mechanical alternatives regarding size, motor power, link length ratio or payload. The four major types of serial kinematics dominating the market are complemented by various parallel kinematics for special purpose. In contrast, few other path planning alternatives are applied in industrial robotics which are based on similar analytic solution principles. The objective of this thesis is to develop a systematic design method for artifacts in motion, to integrate motion design and mechanical design to enable new processes for production. For each design, a theoretical benchmark is developed, which cannot be attained by conventional robots in principle. A key performance indicator enables to measure the degree of goal achievement towards the benchmark during all design phases. Motion behaviors are identified on a local level by dynamic systems modeling and are integrated into new global behavior featuring a new quality, suitable for exceeding the design benchmark in industrial processes. Two exemplary handling robot designs are presented. The first concept enables motion behavior to consume less electrical power than kinetic energy transferred to and from its payload during motion. The second concept enables motion with four degrees of freedom by single motor stimulation, reducing idle power consumption on factor 4 towards conventional robots.

    2006-07-01

    Recent experiences in using participatory methods for ergonomic workplace improvement are reviewed to know how these methods can be effective in different settings. The review covered participatory programmes for managers and workers in small enterprises, home workers, construction workers and farmers in Asian countries. To meet diversifying ergonomic needs, participatory steps reviewed are found to usually follow a good-practice approach easily adjustable according to local needs. These steps are found to usually focus on low-cost improvements. They can thus lead to concrete results particularly by addressing multiple technical areas together. Typical areas include materials handling, workstation design, physical environment and work organization. Further, the review confirms that the participatory methods are always modified according to each local situation. This is done by developing a group-work toolkit comprising action checklists and illustrated manuals and by building a support network of trained trainers. It is suggested that participatory methods taking a good-practice approach by multi-area low-cost improvements through the group use of locally adjusted toolkits are effective for improving small-scale workplaces including those in developing countries.

Technically skilled people are not always available in sufficient numbers. A lot of know how with respect to the required technologies is available but successful adaptive robotic system designs are still rare. In our research at the university of applied sciences we incorporate new available technologies in our education courses by way of research projects; in these projects students will investigate the application possibilities of new technologies together with companies and teachers. Thus we are able to transfer knowledge to the students including an innovation oriented attitude and skills. Last years we developed several industrial binpicking applications for logistics and machining-factories with different types of 3D vision. Also force feedback gripping has been developed including slip sensing. Especially for healthcare robotics we developed a so-called twisted wire actuator, which is very compact in combination with an underactuated gripper, manufactured in one piece in polyurethane. We work both on modeling and testing the functions of these designs but we work also on complete demonstrator systems. Since the amount of disciplines involved in complex product and machine design increases rapidly we pay a lot of attention with respect to systems engineering methods. Apart from the classical engineering disciplines like mechanical, electrical, software and mechatronics engineering, especially for adaptive robotics more and more disciplines like industrial product design, communication … multimedia design and of course physics and even art are to be involved depending on the specific application to be designed.

  17. Introduction: The Participatory Turn in Urbanism

    Directory of Open Access Journals (Sweden)

    2014-08-01

    Full Text Available This issue of Footprint examines the recent participatory turn in urban planning and urban design. It discusses the co-opting of participatory processes by planning departments, the systematic disregard of inequalities, and the empowering of the market resulting from the ‘anti-statism’ present in many participatory schemes.What is the relationship between the institutionalisation of participation and the practices of autonomy, self-organisation, and inclusion? When and how does genuine empowerment of collectives take place? Does the demand for the empowerment of local organisations and communities strengthen the market forces at the expense of central government?This issue attempts to problematise ‘participation’, to call attentions to some of its shortcomings, deficits, and limitations, not in order to necessarily bypass the demand for the democratisation of the urban, but in order to rectify and strengthen it.

  18. Virtual Screening and Structure Generation Applied to Drug Design

    The methods of computer-aided drug design can be divided into two categories according to whether or not the structures of receptors are known1, corresponding to two principal strategies:(1) searching the bio-active ligands against virtual combinatorial libraries and calculating the affinity energy between ligand and receptor by docking ; (2) QSAR and 3D-structure data-mining.3D-QSAR method is now applied widely to drug discovery, but this method is generally limited to refine the structures of known bio-active compounds. During the process of drug design, we have usually the prejudice that certain groups or structural fragments will play or not important roles on the activity. This will sometimes be misleading, and prevent us from obtaining expected results.The method of generating firstly diverse structures, then screening out the promising structures by means of a computational method or QSAR model, is an efficient way for drug discovery. We developed an efficient virtual and rational drag design method. It combines virtual bioactive compound generation using genetic algorithms with 3D-QSAR model and docking. Using this method can generate a lot of highly diverse molecules and find virtual active lead compounds. The method was validated by the study on a set of anti-tumor drugs, colchicine analogs2. With the constraints of pharmacophore obtained determined by DISCO, 97 virtual bioactive compounds were generated,and their anti-tumor activities were predicted by CoMFA. 8 structures with high activity were selected and screened by 3D-QSAR model. The most active generated structure was further investigated by modifying its structure in order to increase the activity (see fig.1). This drug design method could also avoid the conflict between the insufficiency of active structures and the great quantity of compounds needed for high-throughput screening. This method has been also applied to anti-HIV drug design.We have developed equally another approach of virtual

  19. Genetic algorithms applied to nuclear reactor design optimization

    International Nuclear Information System (INIS)

    A genetic algorithm is a powerful search technique that simulates natural evolution in order to fit a population of computational structures to the solution of an optimization problem. This technique presents several advantages over classical ones such as linear programming based techniques, often used in nuclear engineering optimization problems. However, genetic algorithms demand some extra computational cost. Nowadays, due to the fast computers available, the use of genetic algorithms has increased and its practical application has become a reality. In nuclear engineering there are many difficult optimization problems related to nuclear reactor design. Genetic algorithm is a suitable technique to face such kind of problems. This chapter presents applications of genetic algorithms for nuclear reactor core design optimization. A genetic algorithm has been designed to optimize the nuclear reactor cell parameters, such as array pitch, isotopic enrichment, dimensions and cells materials. Some advantages of this genetic algorithm implementation over a classical method based on linear programming are revealed through the application of both techniques to a simple optimization problem. In order to emphasize the suitability of genetic algorithms for design optimization, the technique was successfully applied to a more complex problem, where the classical method is not suitable. Results and comments about the applications are also presented. (orig.)

    Full Text Available The use of participatory sensing in relation to the capture of health-related data is rapidly becoming a possibility due to the widespread consumer adoption of emerging mobile computing technologies and sensing platforms. This has the potential to revolutionize data collection for population health, aspects of epidemiology, and health-related e-Science applications and as we will describe, provide new public health intervention capabilities, with the classifications and capabilities of such participatory sensing platforms only just beginning to be explored. Such a development will have important benefits for access to near real-time, large-scale, up to population-scale data collection. However, there are also numerous issues to be addressed first: provision of stringent anonymity and privacy within these methodologies, user interface issues, and the related issue of how to incentivize participants and address barriers/concerns over participation. To provide a step towards describing these aspects, in this paper we present a first classification of health participatory sensing models, a novel contribution to the literature, and provide a conceptual reference architecture for health participatory sensing networks (HPSNs and user interaction example case study.

    Full Text Available Introduction: In India, medical undergraduates think that statistics is difficult to understand. Often, it is taught just before final assessment examination using didactic lectures, with little use of medical examples and less focus on application. Hence, we prepared interactive, participatory sessions for teaching biostatistics to medical undergraduate. Methods: The sessions were delivered by a facilitator. It had clearly specified objectives and teaching learning strategies. A needs assessment was done by interviewing the students who had undergone traditional biostatistics teaching methodology. Specific learning objectives for the sessions were finalized using the Delphi technique and review of University syllabus. Two trained Community Medicine faculties designed the lesson plans ‘backwards’ from desired outcome to content, teaching/learning strategies, assessment and evaluation process (Outcomes-based lesson planning. Forty, third-semester (Para-clinical phase of the second year medical undergraduates undertook these seven teaching sessions. The session followed adult learning principles and included group discussions, games and reflections. We evaluated the impact of the sessions using in-depth interviews, retrospective post-then-preself- assessment and a pre-announced written test. Results: With traditional statistics teaching methodology, students perceived it as a standalone subject and were not interested in statistics. Students who underwent the sessions commented that the sessions were enjoyable, interesting, and participatory and more than %90 of them felt they were engaged throughout the session. They also narrated various instances where they could apply the biostatistics learning. In the post-then-pre-assessment median post-session scores for all the objectives were significantly higher (p <0.050. Conclusion: Use of interactive, participatory sessions for teaching biostatistics to medical undergraduates resulted in a

    Participatory management and leadership can enhance an organization's effectiveness and capacity by the fact that the only asset a manager has are the people. If people show loyalty, and are willing to work at full capacity and to make extra efforts, if they trust their leaders and feel safe, then the results and efficiency will be increased. The more one can delegate the decision-making and responsibilities, the more loyalty and trust one will have from the employees.

  10. Use of Participatory Systems Dynamics Modelling to Generate User-Friendly Decision Support Systems for the Design of Management Policies for Complex Human-Environmental Systems: A Case Study from the Varied Socio-environmental Landscape of Guatemala

    The design of effective management policies for socioenvironmental systems requires the development of comprehensive, yet sufficiently simple, decision support systems (DSS) for policy makers. Guatemala is a particularly complex case, combining an enormous diversity of climates, geographies, and agroecosystems within a very small geographical scale. Although food insecurity levels are very high, indicating a generally inadequate management of the varied agroecosystems of the country, different regions have shown vastly different trends in food insecurity over the past decade, including between regions with similar geophysical and climatic characteristics and/or governmental programmes (e.g., agricultural support). These observations suggest two important points: firstly, that not merely environmental conditions but rather socio-environmental interactions play a crucial role in the successful management of human-environmental systems, and, secondly, that differences in the geophysical and climatic environments between the diverse regions significantly impact the success or failure of policies. This research uses participatory systems dynamic modelling (SDM) to build a DSS that allows local decision-makers to (1) determine the impact of current and potential policies on agroecosystem management and food security, and (2) design sustainable and resilient policies for the future. The use of participatory SDM offers several benefits, including the active involvement of the end recipients in the development of the model, greatly increasing its acceptability; the integration of physical (e.g., precipitation, crop yield) and social components in one model; adequacy for modelling long-term trends in response to particular policy decisions; and the inclusion of local stakeholder knowledge on system structure and trends through the participatory process. Preliminary results suggest that there is a set of common variables explaining the generally high levels of food insecurity

    Community resilience (CR) is a priority for preparedness, but few models exist. A steering council used community-partnered participatory research to support workgroups in developing CR action plans and hosted forums for input to design a pilot demonstration of implementing CR versus enhanced individual preparedness toolkits. Qualitative data describe how stakeholders viewed CR, how toolkits were developed, and demonstration design evolution. Stakeholders viewed community engagement as facilitating partnerships to implement CR programs when appropriately supported by policy and CR resources. Community engagement exercises clarified motivations and informed action plans (e.g., including vulnerable populations). Community input identified barriers (e.g., trust in government) and CR-building strategies. A CR toolkit and demonstration comparing its implementation with individual preparedness were codeveloped. Community-partnered participatory research was a useful framework to plan a CR initiative through knowledge exchange. PMID:23678916

    Full Text Available Participatory Epidemiology (PE was applied on the Maasai rangeland of northern Tanzania to understand pastoralist’s perceptions of the clinical and epidemiological features of Contagious Caprine Pleuropneumonia (CCPP. The study was conducted during the period of April 2008 and caprine disease event was directed during the period of July 2006 to June 2007. Participatory methods such as Focus Group Discussion (FGD, proportional piling and matrix scoring were used to characterize pastoralist perceived clinical signs and risk factors for CCPP. The estimated mean incidence and case mortality rate of CCPP was 31.6 and 61.4%, respectively. Matrix scoring showed moderate to good agreement between informant groups on the clinical signs and risk factors. It was concluded that PE complimented with local knowledge could generally be used to generate disease information at low cost and therefore assist the design of feasible disease surveillance systems and control programmes at local and national level.

  16. The role of computer modelling in participatory integrated assessments

    International Nuclear Information System (INIS)

    In a number of recent research projects, computer models have been included in participatory procedures to assess global environmental change. The intention was to support knowledge production and to help the involved non-scientists to develop a deeper understanding of the interactions between natural and social systems. This paper analyses the experiences made in three projects with the use of computer models from a participatory and a risk management perspective. Our cross-cutting analysis of the objectives, the employed project designs and moderation schemes and the observed learning processes in participatory processes with model use shows that models play a mixed role in informing participants and stimulating discussions. However, no deeper reflection on values and belief systems could be achieved. In terms of the risk management phases, computer models serve best the purposes of problem definition and option assessment within participatory integrated assessment (PIA) processes

  20. Applying operating experience to design the CANDU 3 process

    International Nuclear Information System (INIS)

    The CANDU 3 is an advanced, smaller (450 MWe), standardized version of the CANDU now being designed for service later in the decade and beyond. The design of this evolutionary nuclear power plant has been carefully planned and organized to gain maximum benefits from new technologies and from world experience to date in designing, building, commissioning and operating nuclear power stations. The good performance record of existing CANDU reactors makes consideration of operating experience from these plants a particularly vital component of the design process. Since the completion of the first four CANDU 6 stations in the early 1980s, and with the continuing evolution of the multi-unit CANDU station designs since then, AECL CANDU has devised several processes to ensure that such feedback is made available to designers. An important step was made in 1986 when a task force was set up to review and process ideas arising from the commissioning and early operation of the CANDU 6 reactors which were, by that time, operating successfully in Argentina and Korea, as well as the Canadian provinces of Quebec and New Brunswick. The task force issued a comprehensive report which, although aimed at the design of an improved CANDU 6 station, was made available to the CANDU 3 team. By that time also, the Institute of Power Operations (INPO) in the U.S., of which AECL is a Supplier Participant member, was starting to publish Good Practices and Guidelines related to the review and the use of operating experiences. In addition, details of significant events were being made available via the INPO SEE-IN (Significant Event Evaluation and Information Network) Program, and subsequently the CANNET network of the CANDU Owners' Group (COG). Systematic review was thus possible by designers of operations reports, significant event reports, and related documents in a continuing program of design improvement. Another method of incorporating operations feedback is to involve experienced utility

    Participatory research in which experts and non-experts are co-researchers in addressing local concerns (also known as participatory action research or community-based research) can be a valuable approach for dealing with the uncertainty of social-ecological systems because it fosters learning among stakeholders and co-production of knowledge. Despite its increased application in the context of natural resources and environmental management, evaluation of participatory research has received little attention. The objectives of this research were to define criteria to evaluate participatory research processes and outcomes, from the literature on participation evaluation, and to apply them in a case study in an artisanal fishery in coastal Uruguay. Process evaluation criteria (e.g., problem to be addressed of key interest to local and additional stakeholders; involvement of interested stakeholder groups in every research stage; collective decision making through deliberation; and adaptability through iterative cycles) should be considered as conditions to promote empowering participatory research. Our research contributes to knowledge on evaluation of participatory research, while also providing evidence of the positive outcomes of this approach, such as co-production of knowledge, learning, strengthened social networks, and conflict resolution.

  4. Optimized Reputable Sensing Participants Extraction for Participatory Sensor Networks

    Directory of Open Access Journals (Sweden)

    2014-01-01

    Full Text Available By collecting data via sensors embedded personal smart devices, sensing participants play a key role in participatory sensor networks. Using information provided by reputable sensing participants ensures the reliability of participatory sensing data. Setting a threshold for the reputation, and those whose reputations are bigger than this value are regarded as reputable. The bigger the threshold value is, the more reliable the extracted reputable sensing participant is. However, if the threshold value is too big, only very limited participatory sensing data can be involved. This may cause unexpected bias in information collection. Existing works did not consider the relationship between the reliability of extracted reputable sensing participants and the ratio of usable participatory sensing data. In this work, we propose a criterion for optimized reputable sensing participant extraction in participatory sensor networks. This is achieved based on the mathematical analysis on the ratio of available participatory sensing data and the reliability of extracted reputable sensing participants. Our suggested threshold value for reputable sensing participant extraction is only related to the power of sensing participant’s reputation distribution. It is easy to be applied in real applications. Simulation results tested on real application data further verified the effectiveness of our proposed method.

    Full Text Available Modern organizations are exposed to diverse external environment influences. Currently accepted concepts of organizational design take into account structure, its interaction with strategy, processes, people, etc. Organization design and planning aims to align this key organizational design variables. At the higher conceptual level, however, completely satisfactory formulation for this alignment doesn’t exist. We develop an approach originating from the application of concepts of theoretical physics to social systems. Under this approach, the allocation of organizational resources is analyzed in terms of social entropy, social free energy and social temperature. This allows us to formalize the dynamic relationship between organizational design variables. In this paper we relate this model to Galbraith's Star Model and we also suggest improvements in the procedure of the complex analytical method in organizational design.

    Faculty members in higher education are involved in many instructional design activities without formal training in learning theories and the science of instruction. Learning theories provide the foundation for the selection of instructional strategies and allow for reliable prediction of their effectiveness. To achieve effective learning outcomes, the science of instruction and instructional design models are used to guide the development of instructional design strategies that elicit appropriate cognitive processes. Here, the major learning theories are discussed and selected examples of instructional design models are explained. The main objective of this article is to present the science of learning and instruction as theoretical evidence for the design and delivery of instructional materials. In addition, this article provides a practical framework for implementing those theories in the classroom and laboratory. PMID:27068989

  7. Self-Adaptive Stepsize Search Applied to Optimal Structural Design

    Science.gov (United States)

    Nolle, L.; Bland, J. A.

    Structural engineering often involves the design of space frames that are required to resist predefined external forces without exhibiting plastic deformation. The weight of the structure and hence the weight of its constituent members has to be as low as possible for economical reasons without violating any of the load constraints. Design spaces are usually vast and the computational costs for analyzing a single design are usually high. Therefore, not every possible design can be evaluated for real-world problems. In this work, a standard structural design problem, the 25-bar problem, has been solved using self-adaptive stepsize search (SASS), a relatively new search heuristic. This algorithm has only one control parameter and therefore overcomes the drawback of modern search heuristics, i.e. the need to first find a set of optimum control parameter settings for the problem at hand. In this work, SASS outperforms simulated-annealing, genetic algorithms, tabu search and ant colony optimization.

  10. Applying axiomatic design to a medication distribution system

    Science.gov (United States)

    Raguini, Pepito B.

    As the need to minimize medication errors drives many medical facilities to come up with robust solutions to the most common error that affects patient's safety, these hospitals would be wise to put a concerted effort into finding methodologies that can facilitate an optimized medical distribution system. If the hospitals' upper management is looking for an optimization method that is an ideal fit, it is just as important that the right tool be selected for the application at hand. In the present work, we propose the application of Axiomatic Design (AD), which is a process that focuses on the generation and selection of functional requirements to meet the customer needs for product and/or process design. The appeal of the axiomatic approach is to provide both a formal design process and a set of technical coefficients for meeting the customer's needs. Thus, AD offers a strategy for the effective integration of people, design methods, design tools and design data. Therefore, we propose the AD methodology to medical applications with the main objective of allowing nurses the opportunity to provide cost effective delivery of medications to inpatients, thereby improving quality patient care. The AD methodology will be implemented through the use of focused stores, where medications can be readily stored and can be conveniently located near patients, as well as a mobile apparatus that can also store medications and is commonly used by hospitals, the medication cart.

    Forest policy decisions are often a source of debate, conflict, and tension in many countries. The debate over forest land-use decisions often hinges on disagreements about societal values related to forest resource use. Disagreements on social value positions are fought out repeatedly at local, regional, national, and international levels at an enormous social cost. Forest policy problems have some inherent characteristics that make them more difficult to deal with. On the one hand, forest policy decisions involve uncertainty, long time scales, and complex natural systems and processes. On the other hand, such decisions encompass social, political, and cultural systems that are evolving in response to forces such as globalization. Until recently, forest policy was heavily influenced by the scientific community and various economic models of optimal resource use. However, growing environmental awareness and acceptance of participatory democracy models in policy formulation have forced the public authorities to introduce new participatory mechanisms to manage forest resources. Most often, the efforts to include the public in policy formulation can be described using the lower rungs of Arnstein’s public participation typology. This paper presents an approach that incorporates stakeholder preferences into forest land-use policy using the Analytic Hierarchy Process (AHP). An illustrative case of regional forest-policy formulation in Australia is used to demonstrate the approach. It is contended that applying the AHP in the policy process could considerably enhance the transparency of participatory process and public acceptance of policy decisions.

  16. A Probabilistic Design Method Applied to Smart Composite Structures

    Science.gov (United States)

    Shiao, Michael C.; Chamis, Christos C.

    1995-01-01

    A probabilistic design method is described and demonstrated using a smart composite wing. Probabilistic structural design incorporates naturally occurring uncertainties including those in constituent (fiber/matrix) material properties, fabrication variables, structure geometry and control-related parameters. Probabilistic sensitivity factors are computed to identify those parameters that have a great influence on a specific structural reliability. Two performance criteria are used to demonstrate this design methodology. The first criterion requires that the actuated angle at the wing tip be bounded by upper and lower limits at a specified reliability. The second criterion requires that the probability of ply damage due to random impact load be smaller than an assigned value. When the relationship between reliability improvement and the sensitivity factors is assessed, the results show that a reduction in the scatter of the random variable with the largest sensitivity factor (absolute value) provides the lowest failure probability. An increase in the mean of the random variable with a negative sensitivity factor will reduce the failure probability. Therefore, the design can be improved by controlling or selecting distribution parameters associated with random variables. This can be implemented during the manufacturing process to obtain maximum benefit with minimum alterations.

    2016-05-01

    Meaningful child participation in medical research is seen as important. In order to facilitate further development of participatory research, we performed a systematic literature study to describe and assess the available knowledge on participatory methods in pediatric research. A search was executed in five databases: PubMed, CINAHL, PsycINFO, Scopus, and Cochrane. After careful screening of relevant papers, finally 24 documents were included in our analysis. Literature on participatory methods in pediatric research appears generally to be descriptive, whereby high-quality evidence is lacking. Overall, five groups of participatory methods for children could be distinguished: observational, verbal, written, visual, and active methods. The choice for one of these methods should be based on the child's age, on social and demographic characteristics, and on the research objectives. To date, these methods are still solely used for obtaining data, yet they are suitable for conducting meaningful participation. This may result in a successful partnership between children and researchers. Researchers conducting participatory research with children can use this systematic review in order to weigh the current knowledge about the participatory methods presented. PMID:26720607

  1. A GOMS model applied to a simplified control panel design

    International Nuclear Information System (INIS)

    The design of the user interface for a new system requires many decisions to be considered. To develop sensitivity to user needs requires understanding user behavior. The how-to-do-it knowledge is a mixture of task-related and interface-related components. A conscientious analysis of these components, allows the designer to construct a model in terms of goals, operators, methods, and selection (GOMS model) rules that can be advantageously used in the design process and evaluation of a user interface. The emphasis of the present work is on describing the importance and use of a GOMS model as a formal user interface analysis tool in the development of a simplified panel for the control of a nuclear power plant. At Pennsylvania State University, a highly automated control system with a greatly simplified human interface has been proposed to improve power plant safety. Supervisory control is to be conducted with a simplified control panel with the following functions: startup, shutdown, increase power, decrease power, reset, and scram. Initial programming of the operator interface has been initiated within the framework of a U.S. Department of Energy funded university project for intelligent distributed control. A hypothesis to be tested is that this scheme can be also used to estimate mental work load content and predict human performance

    In this work, an innovative teaching model applied to methodological contents in psychology is presented. The proposed didactic model includes Information and Communication Technologies (ICT), such as CD-ROMs, web sites and Internet. These resources complement class attendance. In the classes the students are informed, guided and oriented so that they are able to obtain information and reorganize it in a coherent way. The aim of this article is to find out the students' learning preferences and estimate the incorporation of ICT, by means of the ETIM (Evaluation of Teaching Innovation Model) questionnaire. The results show that the students are aware of the need to consult other materials and that ICT helps students to understand the subject from various perspectives. In this way, the students become more autonomous in acquiring learning results. PMID:17296099

  3. Designing Crane Controls with applied Mechanical and Electrical Safety Features

    Lytle, Bradford P.; Walczak, Thomas A.; Delgado, H. (Technical Monitor)

    2002-01-01

    The use of overhead traveling bridge cranes in many varied applications is common practice. In particular, the use of cranes in the nuclear, military, commercial, aerospace, and other industries can involve safety critical situations. Considerations for Human Injury or Casualty, Loss of Assets, Endangering the Environment, or Economic Reduction must be addressed. Traditionally, in order to achieve additional safety in these applications, mechanical systems have been augmented with a variety of devices. These devices assure that a mechanical component failure shall reduce the risk of a catastrophic loss of the correct and/or safe load carrying capability. ASME NOG-1-1998, (Rules for Construction of Overhead and Gantry Cranes, Top Running Bridge, and Multiple Girder), provides design standards for cranes in safety critical areas. Over and above the minimum safety requirements of todays design standards, users struggle with obtaining a higher degree of reliability through more precise functional specifications while attempting to provide "smart" safety systems. Electrical control systems also may be equipped with protective devices similar to the mechanical design features. Demands for improvement of the cranes "control system" is often recognized, but difficult to quantify for this traditionally "mechanically" oriented market. Finite details for each operation must be examined and understood. As an example, load drift (or small motions) at close tolerances can be unacceptable (and considered critical). To meet these high functional demands encoders and other devices are independently added to control systems to provide motion and velocity feedback to the control drive. This paper will examine the implementation of Programmable Electronic Systems (PES). PES is a term this paper will use to describe any control system utilizing any programmable electronic device such as Programmable Logic Controllers (PLC), or an Adjustable Frequency Drive (AID) 'smart' programmable

    2011-01-01

    Traditionally system design has been made from a black box/functionality only perspective which forces the developer to concentrate on how the functionality can be decomposed and recomposed into so called components. While this technique is well established and well known it does suffer fromsome drawbacks; namely that the systems produced can often be forced into certain, incompatible architectures, difficult to maintain or reuse and the code itself difficult to debug. Now that ideas such as the OMG's Model Based Architecture (MDA) or Model Based Engineering (MBE) and the ubiquitous modelling language UML are being used (allegedly) and desired we face a number of challenges to existing techniques.

    The Geo-Environmental Mapping is an improvement of the Geological-Geotechnical Mapping used for basic pipeline designs. The main purpose is to assembly the environmental, geotechnical and geological concepts in a methodological tool capable to predict constrains and reduce the pipeline impact to the environment. The Geo-Environmental mapping was built to stress the influence of soil/structure interaction, related to the physical effect that comes from the contact between structures and soil or rock. A Geological-Geotechnical-Environmental strip (chart) was presented to emphasize the pipeline operational constrains and its influence to the environment. The mapping was developed to clearly show the occurrence and properties of geological materials divided into geotechnical domain units (zones). The strips present construction natural properties, such as: excavability, stability of the excavation and soil re-use capability. Also, the environmental constrains were added to the geological-geotechnical mapping. The Geo-Environmental Mapping model helps the planning of the geotechnical and environmental inquiries to be carried out during executive design, the discussion on the types of equipment to be employed during construction and the analysis of the geological risks and environmental impacts to be faced during the built of the pipeline.

    2015-01-01

    Compounding of medications is an important part of the practice of the pharmacy profession. Because compounded medications do not have U.S. Food and Drug Administration approval, a pharmacist has the responsibility to ensure that compounded medications are of suitable quality, safety, and efficacy. The Federal Government and numerous states have updated their laws and regulations regarding pharmacy compounding as a result of recent quality issues. Compounding pharmacists are expected to follow good preparation prodecures in their compounding practices in much the same way pharmaceutical manufacturers are required to follow Current Good Manufacturing Procedures as detailed in the United States Code of Federal Regulations. Application of Quality by Design concepts to the preparation process for a compounded medication can help in understanding the potential pitfalls and the means to mitigate their impact. The goal is to build quality into the compounding process to ensure that the resultant compounded prescription meets the human or animal patients' requirements. PMID:26891559

  12. The PBIL algorithm applied to a nuclear reactor design optimization

    International Nuclear Information System (INIS)

    The Population-Based Incremental Learning (PBIL) algorithm is a method that combines the mechanism of genetic algorithm with the simple competitive learning, creating an important tool to be used in the optimization of numeric functions and combinatory problems. PBIL works with a set of solutions to the problems, called population, whose objective is create a probability vector, containing real values in each position, that when used in a decoding procedure gives subjects that present the best solutions for the function to be optimized. In this work a new form of learning for algorithm PBIL is developed, having aimed at to reduce the necessary time for the optimization process. This new algorithm will be used in the nuclear reactor design optimization. The optimization problem consists in adjusting several reactor cell parameters, such as dimensions, enrichment and materials, in order to minimize the average peak-factor in a 3-enrichment zone reactor, considering some restrictions. In this optimization is used the computational code HAMMER, and the results compared with other methods of optimization by artificial intelligence. (author)

    2012-12-01

    In recent years an increasing interest in the Moon surface operations has been experienced. In the future robotic and manned missions of Moon surface exploration will be fundamental in order to lay the groundwork for more ambitious space exploration programs. Surface mobility systems will be the key elements to ensure an efficient and safe Moon exploration. Future lunar rovers are likely to be heavier and able to travel longer distances than the previously developed Moon rover systems. The Lunar Roving Vehicle (LRV) is the only manned rover, which has so far been launched and used on the Moon surface. Its mobility system included flexible wheels that cannot be scaled to the heavier and longer range vehicles. Thus the previously developed wheels are likely not to be suitable for the new larger vehicles. Taking all these considerations into account, on the basis of the system requirements and assumptions, several wheel concepts have been discussed and evaluated through a trade-off analysis. Semi-empirical equations have been utilized to predict the wheel geometrical characteristics, as well as to estimate the motion resistances and the ability of the system to generate thrust. A numerical model has also been implemented, in order to define more into the details the whole wheel design, in terms of wheel geometry and physical properties. As a result of the trade-off analysis, the ellipse wheel concept has shown the best behavior in terms of stiffness, mass budget and dynamic performance. The results presented in the paper have been obtained in cooperation with Thales Alenia Space-Italy and Sicme motori, in the framework of a regional program called STEPS . STEPS-Sistemi e Tecnologie per l'EsPlorazione Spaziale is a research project co-financed by Piedmont Region and firms and universities of the Piedmont Aerospace District in the ambit of the P.O.R-F.E.S.R. 2007-2013 program.

    Full Text Available Abstract Background Low back pain (LBP and neck pain (NP are a major public health problem with considerable costs for individuals, companies and society. Therefore, prevention is imperative. The Stay@Work study investigates the (cost-effectiveness of Participatory Ergonomics (PE to prevent LBP and NP among workers. Methods In a randomised controlled trial (RCT, a total of 5,759 workers working at 36 departments of four companies is expected to participate in the study at baseline. The departments consisting of about 150 workers are pre-stratified and randomised. The control departments receive usual practice and the intervention departments receive PE. Within each intervention department a working group is formed including eight workers, a representative of the management, and an occupational health and safety coordinator. During a one day meeting, the working group follows the steps of PE in which the most important risk factors for LBP and NP, and the most adequate ergonomic measures are identified on the basis of group consensus. The implementation of ergonomic measures at the department is performed by the working group. To improve the implementation process, so-called 'ergocoaches' are trained. The primary outcome measure is an episode of LBP and NP. Secondary outcome measures are actual use of ergonomic measures, physical workload, psychosocial workload, intensity of pain, general health status, sick leave, and work productivity. The cost-effectiveness analysis is performed from the societal and company perspective. Outcome measures are assessed using questionnaires at baseline and after 6 and 12 months. Data on the primary outcome as well as on intensity of pain, sick leave, work productivity, and health care costs are collected every 3 months. Discussion Prevention of LBP and NP is beneficial for workers, employers, and society. If the intervention is proven (cost-effective, the intervention can have a major impact on LBP and NP

    Directory of Open Access Journals (Sweden)

    Schellart Antonius JM

    2010-03-01

    Full Text Available Abstract Background Within the working population there is a vulnerable group: workers without an employment contract and workers with a flexible labour market arrangement, e.g. temporary agency workers. In most cases, when sick-listed, these workers have no workplace/employer to return to. Also, for these workers access to occupational health care is limited or even absent in many countries. For this vulnerable working population there is a need for tailor-made occupational health care, including the presence of an actual return-to-work perspective. Therefore, a participatory return-to-work program has been developed based on a successful return-to-work intervention for workers, sick-listed due to low back pain. The objective of this paper is to describe the design of a randomised controlled trial to study the (cost-effectiveness of this newly developed participatory return-to-work program adapted for temporary agency workers and unemployed workers, sick-listed due to musculoskeletal disorders, compared to usual care. Methods/Design The design of this study is a randomised controlled trial with one year of follow-up. The study population consists of temporary agency workers and unemployed workers sick-listed between 2 and 8 weeks due to musculoskeletal disorders. The new return-to-work program is a stepwise program aimed at making a consensus-based return-to-work implementation plan with the possibility of a (therapeutic workplace to return-to-work. Outcomes are measured at baseline, 3, 6, 9 and 12 months. The primary outcome measure is duration of the sickness benefit period after the first day of reporting sick. Secondary outcome measures are: time until first return-to-work, total number of days of sickness benefit during follow-up; functional status; intensity of musculoskeletal pain; pain coping; and attitude, social influence and self-efficacy determinants. Cost-benefit is evaluated from an insurer's perspective. A process evaluation is

  3. An evaluation framework for participatory modelling

    Krueger, T.; Inman, A.; Chilvers, J.

    2012-04-01

    Strong arguments for participatory modelling in hydrology can be made on substantive, instrumental and normative grounds. These arguments have led to increasingly diverse groups of stakeholders (here anyone affecting or affected by an issue) getting involved in hydrological research and the management of water resources. In fact, participation has become a requirement of many research grants, programs, plans and policies. However, evidence of beneficial outcomes of participation as suggested by the arguments is difficult to generate and therefore rare. This is because outcomes are diverse, distributed, often tacit, and take time to emerge. In this paper we develop an evaluation framework for participatory modelling focussed on learning outcomes. Learning encompasses many of the potential benefits of participation, such as better models through diversity of knowledge and scrutiny, stakeholder empowerment, greater trust in models and ownership of subsequent decisions, individual moral development, reflexivity, relationships, social capital, institutional change, resilience and sustainability. Based on the theories of experiential, transformative and social learning, complemented by practitioner experience our framework examines if, when and how learning has occurred. Special emphasis is placed on the role of models as learning catalysts. We map the distribution of learning between stakeholders, scientists (as a subgroup of stakeholders) and models. And we analyse what type of learning has occurred: instrumental learning (broadly cognitive enhancement) and/or communicative learning (change in interpreting meanings, intentions and values associated with actions and activities; group dynamics). We demonstrate how our framework can be translated into a questionnaire-based survey conducted with stakeholders and scientists at key stages of the participatory process, and show preliminary insights from applying the framework within a rural pollution management situation in

    Hassenforder, Emeline; Pittock, Jamie; Barreteau, Olivier; Daniell, Katherine Anne; Ferrand, Nils

    2016-01-01

    Evaluating participatory processes, participatory planning processes especially, can be challenging. Due to their complexity, these processes require a specific approach to evaluation. This paper proposes a framework for evaluating projects that have adopted a participatory planning approach: the monitoring and evaluation of participatory planning processes (MEPPP) framework. The MEPPP framework is applied to one case study, a participatory planning process in the Rwenzori region in Uganda. We suggest that this example can serve as a guideline for researchers and practitioners to set up the monitoring and evaluation of their participatory planning process of interest by following six main phases: (1) description of the case, (2) clarification of the M&E viewpoint(s) and definition of the M&E objective(s), (3) identification of the context, process and outputs/outcomes analytical variables, (4) development of the M&E methods and data collection, (5) data analysis, and (6) sharing of the M&E results. Results of the application of the MEPPP framework in Uganda demonstrate the ability of the framework to tackle the complexity of participatory planning processes. Strengths and limitations of the MEPPP framework are also discussed.

    2014-06-01

    Full Text Available Introduction: Participatory evaluation (PE is a hybrid methodology that can be used simultaneously to investigate and act in groups and communities. It can generate new knowledge about reality, but italso allows changes in the participants and their sociocultural context. This research project, developed over three years, aims to find out whether PE processes are useful and appropriate to evaluate community actionsand to generate learning that contribute to the empowerment of people who develop them.Method: The methodological structure of the research process design Participatory Evaluation processes that are applied in three selected communities-cases, over one year. The steering groups in each caseevaluated four dimensions of Community Development Plans: context, evolution, performance and results, using different techniques and group dynamics. Throughout this process, participants identify the acquiredknowledge and this is linked to indicators of empowerment, using questionnaires, content analysis and semi-structured interviews.Results: The development PE process in the three analyzed cases confirmed that PE is a useful strategy to assess participatory community actions of a territory; to report them to the people of the community; andto make shared decisions, about initiatives in order to improve community actions. The obtained results also verify that, throughout PE, there has been learning in the participants.Conclusions: The involvement of community members in the evaluation makes it more useful, fairer and more valid, but also a fourth positive consequence of PE is empowerment. From the process and the resultsof these cases of Participatory Evaluation, we consider that community EP is social transformation.

    Science.gov (United States)

    Balbale, Salva N; Locatelli, Sara M; LaVela, Sherri L

    2016-08-01

    In this methodological article, we examine participatory methods in depth to demonstrate how these methods can be adopted for quality improvement (QI) projects in health care. We draw on existing literature and our QI initiatives in the Department of Veterans Affairs to discuss the application of photovoice and guided tours in QI efforts. We highlight lessons learned and several benefits of using participatory methods in this area. Using participatory methods, evaluators can engage patients, providers, and other stakeholders as partners to enhance care. Participant involvement helps yield actionable data that can be translated into improved care practices. Use of these methods also helps generate key insights to inform improvements that truly resonate with stakeholders. Using participatory methods is a valuable strategy to harness participant engagement and drive improvements that address individual needs. In applying these innovative methodologies, evaluators can transcend traditional approaches to uniquely support evaluations and improvements in health care. PMID:26667882

    2016-01-01

    Procedures in the development process of crane cabins are arbitrary and subjective. Since approximately 42% of incidents in the construction industry are linked to them, there is a need to collect fresh anthropometric data and provide additional recommendations for design. In this paper, dimensioning of the crane cabin interior space was carried out using a sample of 64 crane operators' anthropometric measurements, in the Republic of Serbia, by measuring workspace with 10 parameters using nine measured anthropometric data from each crane operator. This paper applies experiments run via full factorial designs using a combined traditional and Taguchi approach. The experiments indicated which design parameters are influenced by which anthropometric measurements and to what degree. The results are expected to be of use for crane cabin designers and should assist them to design a cabin that may lead to less strenuous sitting postures and fatigue for operators, thus improving safety and accident prevention.

  11. Co-engineering Participatory Water Management Processes: Theory and Insights from Australian and Bulgarian Interventions

    Directory of Open Access Journals (Sweden)

    Pascal Perez

    2010-12-01

    Full Text Available Broad-scale, multi-governance level, participatory water management processes intended to aid collective decision making and learning are rarely initiated, designed, implemented, and managed by one person. These processes mostly emerge from some form of collective planning and organization activities because of the stakes, time, and budgets involved in their implementation. Despite the potential importance of these collective processes for managing complex water-related social–ecological systems, little research focusing on the project teams that design and organize participatory water management processes has ever been undertaken. We have begun to fill this gap by introducing and outlining the concept of a co-engineering process and examining how it impacts the processes and outcomes of participatory water management. We used a hybrid form of intervention research in two broad-scale, multi-governance level, participatory water management processes in Australia and Bulgaria to build insights into these co-engineering processes. We examined how divergent objectives and conflict in the project teams were negotiated, and the impacts of this co-engineering on the participatory water management processes. These investigations showed: (1 that language barriers may aid, rather than hinder, the process of stakeholder appropriation, collective learning and skills transferal related to the design and implementation of participatory water management processes; and (2 that diversity in co-engineering groups, if managed positively through collaborative work and integrative negotiations, can present opportunities and not just challenges for achieving a range of desired outcomes for participatory water management processes. A number of areas for future research on co-engineering participatory water management processes are also highlighted.

  15. A generalized concept for cost-effective structural design. [Statistical Decision Theory applied to aerospace systems

    Science.gov (United States)

    Thomas, J. M.; Hawk, J. D.

    1975-01-01

    A generalized concept for cost-effective structural design is introduced. It is assumed that decisions affecting the cost effectiveness of aerospace structures fall into three basic categories: design, verification, and operation. Within these basic categories, certain decisions concerning items such as design configuration, safety factors, testing methods, and operational constraints are to be made. All or some of the variables affecting these decisions may be treated probabilistically. Bayesian statistical decision theory is used as the tool for determining the cost optimum decisions. A special case of the general problem is derived herein, and some very useful parametric curves are developed and applied to several sample structures.

Conclusions: The development of LV SP applied to a particular process should follow a sequential model which includes the literature review, the ACR and FMEA methods and consensus.

  17. A participatory modelling approach to developing a numerical sediment dynamics model

    Science.gov (United States)

    Jones, Nicholas; McEwen, Lindsey; Parker, Chris; Staddon, Chad

    2016-04-01

    Fluvial geomorphology is recognised as an important consideration in policy and legislation in the management of river catchments. Despite this recognition, limited knowledge exchange occurs between scientific researchers and river management practitioners. An example of this can be found within the limited uptake of numerical models of sediment dynamics by river management practitioners in the United Kingdom. The uptake of these models amongst the applied community is important as they have the potential to articulate how, at the catchment-scale, the impacts of management strategies of land-use change affect sediment dynamics and resulting channel quality. This paper describes and evaluates a new approach which involves river management stakeholders in an iterative and reflexive participatory modelling process. The aim of this approach was to create an environment for knowledge exchange between the stakeholders and the research team in the process of co-constructing a model. This process adopted a multiple case study approach, involving four groups of river catchment stakeholders in the United Kingdom. These stakeholder groups were involved in several stages of the participatory modelling process including: requirements analysis, model design, model development, and model evaluation. Stakeholders have provided input into a number of aspects of the modelling process, such as: data requirements, user interface, modelled processes, model assumptions, model applications, and model outputs. This paper will reflect on this process, in particular: the innovative methods used, data generated, and lessons learnt.

  18. DSC: software tool for simulation-based design of control strategies applied to wastewater treatment plants.

    Science.gov (United States)

    Ruano, M V; Ribes, J; Seco, A; Ferrer, J

    2011-01-01

    This paper presents a computer tool called DSC (Simulation based Controllers Design) that enables an easy design of control systems and strategies applied to wastewater treatment plants. Although the control systems are developed and evaluated by simulation, this tool aims to facilitate the direct implementation of the designed control system to the PC of the full-scale WWTP (wastewater treatment plants). The designed control system can be programmed in a dedicated control application and can be connected to either the simulation software or the SCADA of the plant. To this end, the developed DSC incorporates an OPC server (OLE for process control) which facilitates an open-standard communication protocol for different industrial process applications. The potential capabilities of the DSC tool are illustrated through the example of a full-scale application. An aeration control system applied to a nutrient removing WWTP was designed, tuned and evaluated with the DSC tool before its implementation in the full scale plant. The control parameters obtained by simulation were suitable for the full scale plant with only few modifications to improve the control performance. With the DSC tool, the control systems performance can be easily evaluated by simulation. Once developed and tuned by simulation, the control systems can be directly applied to the full-scale WWTP.

    2005-01-01

    Full Text Available The article consists of two parts. The first deals with the theoretical framework of urban rehabilitation. Literature provides the basis for a conclusion, which is that the key issue in rehabilitation projects is legitimate negotiation of various interests between participating individuals and institutions. In the second part this presentation and analyses of events that took place at the urban design workshop organised within the framework of the research project Renewal of housing estates in Ljubljana, provide experiential confirmation of the starting thesis. We established that the directly involved residents were willing to actively participate in rehabilitation procedures, however the process is never triggered, because of insufficient capacities in institutional frameworks. In conclusion several real proposals are shown, namely, how to surmount obstacles in urban rehabilitation and especially in larger housing estates built after World War 2.

  7. A methodology for the geometric design of heat recovery steam generators applying genetic algorithms

    International Nuclear Information System (INIS)

    This paper shows how the geometric design of heat recovery steam generators (HRSG) can be achieved. The method calculates the product of the overall heat transfer coefficient (U) by the area of the heat exchange surface (A) as a function of certain thermodynamic design parameters of the HRSG. A genetic algorithm is then applied to determine the best set of geometric parameters which comply with the desired UA product and, at the same time, result in a small heat exchange area and low pressure losses in the HRSG. In order to test this method, the design was applied to the HRSG of an existing plant and the results obtained were compared with the real exchange area of the steam generator. The findings show that the methodology is sound and offers reliable results even for complex HRSG designs. -- Highlights: ► The paper shows a methodology for the geometric design of heat recovery steam generators. ► Calculates product of the overall heat transfer coefficient by heat exchange area as a function of certain HRSG thermodynamic design parameters. ► It is a complement for the thermoeconomic optimization method. ► Genetic algorithms are used for solving the optimization problem

    Hess, R. A.; Gorder, P. J.

    1992-01-01

    Quantitative Feedback Theory describes a frequency-domain technique for the design of multi-input, multi-output control systems which meet time or frequency domain performance criteria when specified uncertainty exists in the linear description of the vehicle dynamics. Quantitative Feedback Theory is applied to the design of the longitudinal flight control system for a linear uncertain model of the AH-64 rotorcraft. In this model, the uncertainty is assigned, and is assumed to be attributable to actual uncertainty in the dynamic model and to the changes in the vehicle aerodynamic characteristics which occur near hover. The model includes an approximation to the rotor and actuator dynamics. The design example indicates the manner in which handling qualities criteria may be incorporated into the design of realistic rotorcraft control systems in which significant uncertainty exists in the vehicle model.

  9. Applying Monte Carlo Simulation to Launch Vehicle Design and Requirements Verification

    Science.gov (United States)

    Hanson, John M.; Beard, Bernard B.

    2010-01-01

    This paper is focused on applying Monte Carlo simulation to probabilistic launch vehicle design and requirements verification. The approaches developed in this paper can be applied to other complex design efforts as well. Typically the verification must show that requirement "x" is met for at least "y" % of cases, with, say, 10% consumer risk or 90% confidence. Two particular aspects of making these runs for requirements verification will be explored in this paper. First, there are several types of uncertainties that should be handled in different ways, depending on when they become known (or not). The paper describes how to handle different types of uncertainties and how to develop vehicle models that can be used to examine their characteristics. This includes items that are not known exactly during the design phase but that will be known for each assembled vehicle (can be used to determine the payload capability and overall behavior of that vehicle), other items that become known before or on flight day (can be used for flight day trajectory design and go/no go decision), and items that remain unknown on flight day. Second, this paper explains a method (order statistics) for determining whether certain probabilistic requirements are met or not and enables the user to determine how many Monte Carlo samples are required. Order statistics is not new, but may not be known in general to the GN&C community. The methods also apply to determining the design values of parameters of interest in driving the vehicle design. The paper briefly discusses when it is desirable to fit a distribution to the experimental Monte Carlo results rather than using order statistics.

  10. Design and simulation of high-voltage Applied-B ion diodes for inertial confinement fusion

    International Nuclear Information System (INIS)

    We present the design of the high-voltage (30 MV) Applied-B ion diode that is now being tested on the PBFA-II accelerator at Sandia National Laboratories. This diode design is the first application of a new set of numerical design tools that have been developed over the past several years. Furthermore, this design represents significant departures from previous designs due to much higher voltage and the use of a nonprotonic ion, Li+. The higher voltage increases the magnetic field strength required to insulate the diode from 1 to 2 T of previous diodes to 3--7 T. This represents a very large increase in the magnetic field energy and the magnetic forces exerted on the field-coil structures. Our new design incorporates changes in the field-coil locations to significantly reduce the field energy and the forces on the field-coil structures. The use of nonprotonic ions introduces a new complication in that these ions will be stripped when they penetrate material, i.e., the gas cell membrane. The importance of current neutralization, charge-exchange reactions, and the conservation of canonical angular momentum are discussed in the context of designing light ion diodes suitable as drivers for inertial confinement fusion. We have simulated the performance of this diode design using the electromagnetic particle-in-cell code, magIc. We find that the most sensitive point in the power flow is the transition from the self-magnetically insulated transmission line to the applied field region of the diode

  11. Applying observations of work activity in designing prototype data analysis tools

    Energy Technology Data Exchange (ETDEWEB)

    Springmeyer, R.R.

    1993-07-06

    Designers, implementers, and marketers of data analysis tools typically have different perspectives than users. Consequently, data analysis often find themselves using tools focused on graphics and programming concepts rather than concepts which reflect their own domain and the context of their work. Some user studies focus on usability tests late in development; others observe work activity, but fail to show how to apply that knowledge in design. This paper describes a methodology for applying observations of data analysis work activity in prototype tool design. The approach can be used both in designing improved data analysis tools, and customizing visualization environments to specific applications. We present an example of user-centered design for a prototype tool to cull large data sets. We revisit the typical graphical approach of animating a large data set from the point of view of an analysis who is culling data. Field evaluations using the prototype tool not only revealed valuable usability information, but initiated in-depth discussions about user`s work, tools, technology, and requirements.

    In order to increase the applying rate of liquid fertilizer and reduce environmental pollution, a slave computer control system for applying variable-rate liquid fertilizer was designed. The system used SMC as core processor and electrically controlled pressure regulator as execution component. The characteristic equation of the system was obtained by using classical control theory. Results indicated that the characteristic equation met the requirements of routh-criterion, which indicated the working process of the system was stable. Performance of the slave computer was verified via bench tests. Results demonstrated that there was no significant influence on the response from interclass error. The fertilization error was less than 0.9, and the fertilization accuracy was larger than 97%. The liquid fertilizer emitted by the fertilizing devices had no significant difference in uniformity, which met the demands of the slave computer control system for applying variable-rate liquid fertilizer.

    Denis SALLES

    2014-07-01

    Full Text Available This paper considers the social and scientific requirements for a citizen science monitoring programme on biodiversity in Arcachon Bay (France. The sociological study reveals tensions between different conceptions of what a citizen science programme should be: a means for storing oriented-data; a new way to co-create scientific knowledge; a political communication tool; a way to develop citizen stewardship; or a place for expressing activist environmental demands. Citizen science programmes also tend to reveal tensions between participatory governance and classical management of environmental issues. Despite a seeming consensus amongst actors on biodiversity conservation, in practice contests over different citizen science conceptions have the potential to re-define environmental issues, to re-specify relationships between science and society and outline new management priorities.

    2016-03-01

    Full Text Available Background: Limpopo Province is one of the hardest hit by tuberculosis and human immune virus infections in the country. The province has been implementing directly observed treatment strategy since 1996. However, the cure rate was 64% in 2015 and remains far from the set target by the World Health Organization of 85%. Poor health-care seeking and adherence behaviours were identified as major risk behaviours.Aim: To apply a community-based participatory research approach in identifying barriers and facilitators to health-care seeking and adherence to treatment, and to determine strategies and messages in order to inform the design of an adapted intervention programme.Setting: This study was conducted in three districts in the Limpopo Province, Capricorn, Mopani and Sekhukhune districts.Methods: Community participatory research approach was applied. Purposive sampling was used to sample participants. Focus group discussions were used to collect data. Participatory analysis was used comparing findings within and across all the participants.Results: A total of 161 participated in the study. Participants included coordinators, professional nurses, supporters and patients. Major modifiable behavioural-related barriers were lack of knowledge about tuberculosis, misinformation and misperceptions cultural beliefs, stigma and refusal of treatment support. Environment-related barriers were attitudes of health workers, lack of support by family and community, lack of food and use of alcohol and drugs. Strategies and messages included persuasive and motivational messages to promote healthy behaviour.Conclusion: Joint programmatic collaboration between the community and academic researchers is really needed for interventions to address the needs of the community.Keywords: Health seeking, Adherence, Community based participatory research, Tuberculosis

  17. From Citizen Participation to Participatory Governance

    2009-01-01

    Full Text Available This paper identifies types of citizen participation in local government in Australia, in particular focusing on the past two decades when local government systems have been the focus of intense reform. The paper considers the extent to which contemporary views of participatory governance have taken root at local and sub-local levels and concludes that despite reforms intended to engage local citizens more in local government activity, citizen participation has yet to develop significantly into arrangements that reach the level of participatory governance. It also argues that for participatory governance to be further developed, leadership may often have to come from organisations outside institutional local government.

    International Nuclear Information System (INIS)

    As the health care revolution progresses, so must the management styles of today's leaders. The authors must ask ourselves if we are managing tomorrow's work force or the work force of the past. Participatory management may better meet the needs of today's work force. This paper identifies the reasons participatory management is a more effective management style, the methods used to implement a participatory management program, its benefits (such as higher productivity and more efficient, effective implementation and acceptance of change), and the difficulties experienced

  19. Applying design principles to fusion reactor configurations for propulsion in space

    Science.gov (United States)

    Carpenter, Scott A.; Deveny, Marc E.; Schulze, Norman R.

    1993-01-01

    We applied three design principles (DPs) to adapt and optimize three candidate-terrestrial-fusion-reactor configurations for propulsion in space. The three design principles are: (1) provide maximum direct access to space for waste radiation, (2) operate components as passive radiators to minimize cooling-system mass, and (3) optimize the plasma fuel, fuel mix, and temperature for best specific Jet power. The three candidate-terrestrial-fusion-reactor configurations are: (1) the thermal-barrier-tandem-mirror (TBTM), (2) field-reversed-mirror (FRM), and (3) levitated-dipole-field (LDF). The resulting three candidate-space-fusion-propulsion systems have their initial-mass-to-LEO minimized and their specific jet power and reusability maximized. We performed a preliminary rating of these configurations and concluded that the leading engineering-design solution to space fusion propulsion is a modified TBTM that we call the Mirror Fusion Propulsion System.

  1. Applying ILT mask synthesis for co-optimizing design rules and DSA process characteristics

    Science.gov (United States)

    Dam, Thuc; Stanton, William

    2014-03-01

    During early stage development of a DSA process, there are many unknown interactions between design, DSA process, RET, and mask synthesis. The computational resolution of these unknowns can guide development towards a common process space whereby manufacturing success can be evaluated. This paper will demonstrate the use of existing Inverse Lithography Technology (ILT) to co-optimize the multitude of parameters. ILT mask synthesis will be applied to a varied hole design space in combination with a range of DSA model parameters under different illumination and RET conditions. The design will range from 40 nm pitch doublet to random DSA designs with larger pitches, while various effective DSA characteristics of shrink bias and corner smoothing will be assumed for the DSA model during optimization. The co-optimization of these design parameters and process characteristics under different SMO solutions and RET conditions (dark/bright field tones and binary/PSM mask types) will also help to provide a complete process mapping of possible manufacturing options. The lithographic performances for masks within the optimized parameter space will be generated to show a common process space with the highest possibility for success.

  2. Experimental Investigation on Adaptive Robust Controller Designs Applied to Constrained Manipulators

    Directory of Open Access Journals (Sweden)

    Marco H. Terra

    2013-04-01

    Full Text Available In this paper, two interlaced studies are presented. The first is directed to the design and construction of a dynamic 3D force/moment sensor. The device is applied to provide a feedback signal of forces and moments exerted by the robotic end-effector. This development has become an alternative solution to the existing multi-axis load cell based on static force and moment sensors. The second one shows an experimental investigation on the performance of four different adaptive nonlinear H∞ control methods applied to a constrained manipulator subject to uncertainties in the model and external disturbances. Coordinated position and force control is evaluated. Adaptive procedures are based on neural networks and fuzzy systems applied in two different modeling strategies. The first modeling strategy requires a well-known nominal model for the robot, so that the intelligent systems are applied only to estimate the effects of uncertainties, unmodeled dynamics and external disturbances. The second strategy considers that the robot model is completely unknown and, therefore, intelligent systems are used to estimate these dynamics. A comparative study is conducted based on experimental implementations performed with an actual planar manipulator and with the dynamic force sensor developed for this purpose.

  4. Methodology for risk assessment and reliability applied for pipeline engineering design and industrial valves operation

    Two kinds of situations may be distinguished for estimating the operating reliability when maneuvering industrial valves and the probability of undesired events in pipelines and industrial plants: situations in which the risk is identified in repetitive cycles of operations and situations in which there is a permanent hazard due to project configurations introduced by decisions during the engineering design definition stage. The estimation of reliability based on the influence of design options requires the choice of a numerical index, which may include a composite of human operating parameters based on biomechanics and ergonomics data. We first consider the design conditions under which the plant or pipeline operator reliability concepts can be applied when operating industrial valves, and then describe in details the ergonomics and biomechanics risks that would lend itself to engineering design database development and human reliability modeling and assessment. This engineering design database development and reliability modeling is based on a group of engineering design and biomechanics parameters likely to lead to over-exertion forces and working postures, which are themselves associated with the functioning of a particular plant or pipeline. This approach to construct based on ergonomics and biomechanics for a more common industrial valve positioning in the plant layout is proposed through the development of a methodology to assess physical efforts and operator reach, combining various elementary operations situations. These procedures can be combined with the genetic algorithm modeling and four elements of the man-machine systems: the individual, the task, the machinery and the environment. The proposed methodology should be viewed not as competing to traditional reliability and risk assessment bur rather as complementary, since it provides parameters related to physical efforts values for valves operation and workspace design and usability.

  5. Robust design of reactor power control system with genetic algorithm-applied weighting functions

    International Nuclear Information System (INIS)

    The H∞ algorithms of the mixed weight sensitivity is used for the robust design of the reactor power control system. The mixed weight sensitivity method requires the selection of the proper weighting functions for the loop shaping in frequency domain. The complexity of the system equation and the non-convexity of the problem make it very difficult to determine the weighting functions. The genetic algorithm which is improved and hybridized with the simulated annealing is applied to determine the weighting functions. This approach permits an automatic calculation and the resultant system shows good robustness and performance. (author)

    A hybridization of the recently introduced Particle Collision Algorithm (PCA) and the Nelder-Mead Simplex algorithm is introduced and applied to a core design optimization problem which was previously attacked by other metaheuristics. The optimization problem consists in adjusting several reactor cell parameters, such as dimensions, enrichment and materials, in order to minimize the average peak-factor in a three-enrichment-zone reactor, considering restrictions on the average thermal flux, criticality and sub-moderation. The new metaheuristic performs better than the genetic algorithm, particle swarm optimization, and the Metropolis algorithms PCA and the Great Deluge Algorithm, thus demonstrating its potential for other applications

    International Nuclear Information System (INIS)

    Actual work defines the thermal design methodology for pressure electroslag remelting furnaces (P ESR) of variable capacity, applied for 5 Kg. It begins with classification and description of secondary refining furnaces, after PESR process and the concept of thermal design are described. Next, in base of the steel weight to remelt (5 Kg); ingot, crucible and electrode dimensions are obtained. These elements will be inside of pressure vessel whose thickness are determined according to ASME Code (Section 8, Division 1, U G-27). It was developed a computer program, where the furnace capacity can be modified, so like other conditions, and display principal dimensions of the furnace. Current and voltage are obtained from the heat necessary to remelt the ingot and the heat transfer in the crucible, is analysed because of it is the most critical element. It was selected too the equipment to registry temperatures and pressure in base of thermocouple characteristics. (Author)

  10. Experience in the use of FBR core component structural design criteria as applied to FFTF

    Energy Technology Data Exchange (ETDEWEB)

    Hecht, S.L.

    1979-01-01

    User gained experience resulting from trial applications of proposed structural design guidelines for Fast Breeder Reactor (FBR) core components is presented. This work was done supporting the design analyses process for consumable core components for the Fast Test Reactor (FTR) of the Fast Flux Test Facility (FFTF). The proposed guidelines were found to be more comprehensive and generally easier to apply than those methods previously used. Component evaluation required a minimum amount of detailed inelastic analysis, primarily through the use of simplified inelastic analysis methods, as given in the guidelines. A major shortcoming of this draft criteria/guidelines is a lack of supporting irradiated material properties. Some areas of guidance given seems ambiguous and may be non-conservative, particularly those related to stress classification unique to FBR environments. Further verification of these areas appears to be in order.

  11. Practices and rules applied for the design of large dry PWR-containments within EC countries

    International Nuclear Information System (INIS)

    The containment system is an essential component of nuclear power plants and its behaviour plays an important role in the evaluation of accident consequences of pressurized water reactors. The present report illuminates the analytical methods for the simulation of the thermohydraulic loads and the experimental background to support these methods. The national rules and practices applied within the EC member countries to determine the local and global design loads were compared. For thermohydraulic load prediction only small differences have been found, particularly in the required safety addition factors covering the uncertainties of the predictive analytical simulation procedures. Comparison of design loads shows in general that analytical methods are comparable throughout the EC member countries and, with regard to their determination, warrant to a large extent an equal degree of conservatism

    In this study, a neuro-fuzzy controller which has the characteristic of fuzzy control and artificial neural network is designed. A fuzzy rule to be applied is automatically selected by the allocated neurons. The neurons correspond to fuzzy rules are created by an expert. To adapt the more precise model is implemented by error back-propagation learning algorithm to adjust the link-weight of fuzzy membership function in the neuro-fuzzy controller. The more classified fuzzy rule is used to include the property of dual mode method. In order to verify the effectiveness of the proposed algorithm designed above, an operating characteristic of a DC servo motor with variable load is investigated.

  13. Design of digital adjustor applied to power supply system for HIRFL-CSR

    International Nuclear Information System (INIS)

    The control of power supply is the key point in the design of HIRFL-CSR system. Based on ARM + FPGA + AD/DA and state-space equation techniques, the design of digital adjustor applied in the power supply system for HIRFL-CSR in Lanzhou is realized. The digital adjustor can accomplish an adjustment control of fifth order and lower. ARM is used as the core of the control system to deal with the multi-threaded task and the precision of power adjustment control is implemented mainly by FPGA and AD/DA techniques. The embedded gigabit fiber interface can transmit the digital signal from external DSP board and the system uses optoelectronic isolator to inhibit interference signals for 32 bit input/output digital signals. Field test has proved that this digital adjustor can meet HIRFL-CSR's control precision requirement of 10-4 and reduce the recovery time of power system devices. (authors)

    Sample McMeeking, L. B.; Weinberg, A. E.

    2013-12-01

    Research experiences for undergraduates (REU) have been shown to be effective in improving undergraduate students' personal/professional development, ability to synthesize knowledge, improvement in research skills, professional advancement, and career choice. Adding to the literature on REU programs, a new conceptual model situating REU within a context of participatory action research (PAR) is presented and compared with data from a PAR-based coastal climate research experience that took place in Summer 2012. The purpose of the interdisciplinary Participatory Action Research Experiences for Undergraduates (PAREU) model is to act as an additional year to traditional, lab-based REU where undergraduate science students, social science experts, and community members collaborate to develop research with the goal of enacting change. The benefits to traditional REU's are well established and include increased content knowledge, better research skills, changes in attitudes, and greater career awareness gained by students. Additional positive outcomes are expected from undergraduate researchers (UR) who participate in PAREU, including the ability to better communicate with non-scientists. With highly politicized aspects of science, such as climate change, this becomes especially important for future scientists. Further, they will be able to articulate the relevance of science research to society, which is an important skill, especially given the funding climate where agencies require broader impacts statements. Making science relevant may also benefit URs who wish to apply their science research. Finally, URs will gain social science research skills by apprenticing in a research project that includes science and social science research components, which enables them to participate in future education and outreach. The model also positively impacts community members by elevating their voices within and outside the community, particularly in areas severely underserved

  15. Design of diode-pumped solid-state laser applied in laser fuses

    Deng, FangLin; Zhang, YiFei

    2005-04-01

    The function of laser fuzes which are parts of certain weapon systems is to control the blasting height of warheads. Commonly the battle environment these weapon systems are confronted with is very complicated and the tactical demand for them is very rigor, so laser fuzes equipped for them must fulfill some special technical requirements, such as high repetition rate, long ranging scope, etc. Lasers are one of key components which constitute fuze systems. Whether designed lasers are advanced and reasonable will determine whether laser fuzes can be applied in these weapon systems or not. So we adopt the novel technology of diode-pumped solid-state laser (DPSSL) to design lasers applied in fuzes. Nd:YVO4 crystal is accepted as gain material, which has wide absorption band and large absorption efficient for 808nm pumping laser. As warhead's temperature is usually very high, wider absorption band is beneficial to reduce the influence of temperature fluctuation. Passive Q-switching with Cr4+:YAG is used to reduce the power consumption farthest. Design the end-pumped microchip sandwich-architecture to decrease lasers' size and increase the reliability, further it's advantageous to produce short pulses and increase peak power of lasers. The designed DPSSL features small size and weight, high repetition rate and peak power, robustness, etc. The repetition rate is expected to reach 1 kHz; peak power will exceed 300 kW; pulse width is only 5 ns; and divergence angle of laser beams is less than 5 mrad. So DPSSL is suitable for laser fuzes as an emitter.

    2009-12-01

    In spite of many efforts, the geosciences remain less diverse than the overall population of the United States and even other sciences. This lack of diversity threatens the quality of the science, the long-term viability of our workforce, and the ability to leverage scientific insight in service of societal needs. Drawing on new research into diversity specific to geosciences, this talk will explore underlying causes for the lack of diversity in the atmospheric and related sciences. Causes include the few geoscience majors available at institutions with large minority enrollment; a historic association of the geosciences with extractive industries which are negatively perceived by many minority communities, and the perception that science offers less opportunity for service than other fields. This presentation suggests a new approach - community-based participatory research (CBPR). In CBPR, which was first applied in the field of rural development and has been used for many years in biomedical fields, scientists and community leaders work together to design a research agenda that simultaneously advances basic understanding and addresses community priorities. Good CBPR integrates research, education and capacity-building. A CBRP approach to geoscience can address the perceived lack of relevance and may start to ameliorate a history of negative experiences of geosciences. Since CBPR works best when it is community-initiated, it can provide an ideal place for Minority-Serving Institutions to launch their own locally-relevant programs in the geosciences. The presentation will conclude by describing three new examples of CBPR. The first is NCAR’s partnerships to explore climate change and its impact on Tribal lands. The second approach a Denver-area listening conference that will identify and articulate climate-change related priorities in the rapidly-growing Denver-area Latino community. Finally, we will describe a Google-funded project that brings together

    We devised a participatory modeling approach for setting management thresholds that show when management intervention is required to address undesirable ecosystem changes. This approach was designed to be used when management thresholds: must be set for environmental indicators in the face of multiple competing objectives; need to incorporate scientific understanding and value judgments; and will be set by participants with limited modeling experience. We applied our approach to a case study where management thresholds were set for a mat-forming brown alga, Hormosira banksii, in a protected area management context. Participants, including management staff and scientists, were involved in a workshop to test the approach, and set management thresholds to address the threat of trampling by visitors to an intertidal rocky reef. The approach involved trading off the environmental objective, to maintain the condition of intertidal reef communities, with social and economic objectives to ensure management intervention was cost-effective. Ecological scenarios, developed using scenario planning, were a key feature that provided the foundation for where to set management thresholds. The scenarios developed represented declines in percent cover of H. banksii that may occur under increased threatening processes. Participants defined 4 discrete management alternatives to address the threat of trampling and estimated the effect of these alternatives on the objectives under each ecological scenario. A weighted additive model was used to aggregate participants' consequence estimates. Model outputs (decision scores) clearly expressed uncertainty, which can be considered by decision makers and used to inform where to set management thresholds. This approach encourages a proactive form of conservation, where management thresholds and associated actions are defined a priori for ecological indicators, rather than reacting to unexpected ecosystem changes in the future.

    The development of ICT infrastructures has facilitated the emergence of new paradigms for looking at society and the environment over the last few years. Participatory environmental sensing, i.e. directly involving citizens in environmental monitoring, is one example, which is hoped to encourage learning and enhance awareness of environmental issues. In this paper, an analysis of the behaviour of individuals involved in noise sensing is presented. Citizens have been involved in noise measuring activities through the WideNoise smartphone application. This application has been designed to record both objective (noise samples) and subjective (opinions, feelings) data. The application has been open to be used freely by anyone and has been widely employed worldwide. In addition, several test cases have been organised in European countries. Based on the information submitted by users, an analysis of emerging awareness and learning is performed. The data show that changes in the way the environment is perceived after repeated usage of the application do appear. Specifically, users learn how to recognise different noise levels they are exposed to. Additionally, the subjective data collected indicate an increased user involvement in time and a categorisation effect between pleasant and less pleasant environments. PMID:24349102

    Full Text Available Monitoring of species and their ecosystem attributes is a fundamental requirement in applied ecology and conservation. However, landscape scale monitoring requires an immense effort and commitment, especially when species have a wide distribution or are migratory in nature. Participatory monitoring, whereby local communities are engaged, is increasingly being proposed to address landscape scale monitoring. Its implementation is met with many challenges related to finances, motivation of the local people, lack of trained manpower, and nondirect legal use of the species in question. It is of interest to determine what makes a participatory monitoring program interesting for locals to ensure their long term engagement. Using the unique 26-year program of hunters' observations of moose (Alces alces in Sweden as a case study, we present the evolution of this highly successful participatory monitoring program and show that tackling the motivation to monitor, early involvement of local NGOs, social activities revolving around use of the resource, the biology and economic value of the species, and technical and practical aspects related to the monitoring, together create a successful participatory monitoring program. When users benefit directly from the resource, participate in conservation/management decision making, socialize with other participants, and get rewards for their commitment and effective monitoring, participatory monitoring schemes can then become rewarding and sustainable.

  4. Design & Choice of Media by Applying the Theory of Transactional Distance

    2004-01-01

    This Paper presents a series of empirical studies involving approx.850 students to show how flexibility in course design should be informed by the student's culture and native language (L1), gender, and age, and explains how to decide on the most appropriate learning technology in course design by applying the Theory of Transactional Distance. Curves are presented to show how academic English reading rates online and offline are affected by the L1, gender, and age (over a wide age range 18 81 years old). To prevent inequitable culturally distinct overload, course design should be modified using hypertext. Choice of media--in particular synchronous versus asynchronous media--is decided according to the Theory of Transactional Distance. This theory is here extended from tutor to one student to multiple students in a group, and the masculinity can be modified. Briefly, at initial maximal distance (D-S-) early on, the community is fostered with synchronous media for cooperative group learning, followed by (D-S+) collaborative learning using one of two frameworks presented to ensure constructivism in asynchronous mode, then (D-S+) collaborative for Guided Didactic Conversation in asynchronous mode, and finally (D+ S-) cooperatively in synchronous mode for reflective sharing of course learning experiences. At each transactional distance, or in each mode, hypertext is purposively designed to complement the cooperative or collaborative style to provide self access support (additional analysis and reasoning to cooperative, and examples to collaborative) to provide equitable content and quality of learning across wide cultural and L1 ranges, to remove gender bias, and to accommodate variations due to student age. Thus, to promote student autonomy and lifelong learning.

    Many participatory processes fail to generate social change and collaborative outcomes. This failure can partly be explained by how divergent stakeholders' frames are handled. This paper builds on the framing and participation literature to explain how facilitators can manage frame diversity and foster collaborative outcomes. It suggests two pragmatic steps: identifying frames and managing frames. The two steps are applied to a participatory process for natural resource management in Fogera, Ethiopia. Effectiveness of facilitators' strategies to manage frame diversity in the Fogera case is discussed. Two main elements challenging effectiveness are identified: counter-strategies used by facilitators and most-powerful stakeholders, and the constraining factors knowledge, champions and frame sponsorship. We argue that these elements need to be taken into account by participatory process facilitators when managing frame diversity. PMID:27107955

    The axial flow turbine applied in an overtopping wave energy convertor can continuously provide power with high efficiency and reliably. To study the rules between parameters of the turbine and flows, three different types of turbines with complete 3D flow-channel models were designed and optimized. It appears that diameter of the runner, flow rates, number of guide vanes and shape of outflow passage have a considerable impact on the performance of the whole convertor. The turbine with a diameter of 0.8 m, flow rate of 0.5 m3/s, double guide vanes and bent section in outflow passage shows the best comprehensive performance. Moreover, the results of the experiments indicate that the output power can be enhanced by increasing the wave overtopping rate.

  7. Effectiveness of an Applied Microbiology Course Specifically Designed for Chemical Engineering Majors

    2009-12-01

    Full Text Available In recent years, the disciplines of microbiology and chemical engineering have developed an increasing convergence. To meet the needs of their future employers, today’s chemical engineering students must receive some background in microbiology. This report describes the development and content of “Biological Systems and Applications,” a novel course specifically designed to provide basic biology and applied microbiology knowledge, skills, and experience to sophomore chemical engineering majors. Data collected from entrance and exit surveys of the students demonstrated that the course is successful. The importance of the “project-base” learning technique and of interdisciplinary faculty-student and faculty-faculty collaborations are proposed as elements essential to the success of this particular course.

    , and that (2) the AMF terminates optimization erroneously when the optimization problems have constraints. The first problem is due to inaccuracy in computing derivatives in the AMF, and the second problem is due to erroneous treatment of the trust region ratio, which sets the size of the domain for an optimization in the AMF. In order to solve the first problem of the AMF, automatic differentiation (AD) technique, which reads the codes of analysis models and automatically generates new derivative codes based on some mathematical rules, is applied. If derivatives are computed with the generated derivative code, they are analytical, and the required computational time is independent of the number of design variables, which is very advantageous for realistic aerospace engineering problems. However, if analysis models implement iterative computations such as computational fluid dynamics (CFD), which solves system partial differential equations iteratively, computing derivatives through the AD requires a massive memory size. The author solved this deficiency by modifying the AD approach and developing a more efficient implementation with CFD, and successfully applied the AD to general CFD software. In order to solve the second problem of the AMF, the governing equation of the trust region ratio, which is very strict against the violation of constraints, is modified so that it can accept the violation of constraints within some tolerance. By accepting violations of constraints during the optimization process, the AMF can continue optimization without terminating immaturely and eventually find the true optimum design point. With these modifications, the AMF is referred to as "Robust AMF," and it is applied to airfoil and wing aerodynamic design problems using Euler CFD software. The former problem has 21 design variables, and the latter 64. In both problems, derivatives computed with the proposed AD method are first compared with those computed with the finite

    2004-01-01

    Based on a level set model,a topology optimization method has been suggested recently.It uses a level set to express the moving structural boundary,which can flexibly handle complex topological changes.By combining vector level set models with gradient projection technology,the level set method for topological optimization is extended to a topological optimization problem with multi-constraints,multi-materials and multi-load cases.Meanwhile,an appropriate nonlinear speed mapping is established in the tangential space of the active constraints for a fast convergence.Then the method is applied to structure designs,mechanism and material designs by a number of benchmark examples.Finally,in order to further improve computational efficiency and overcome the difficulty that the level set method cannot generate new material interfaces during the optimization process,the topological derivative analysis is incorporated into the level set method for topological optimization,and a topological derivative and level set algorithm for topological optimization is proposed.

  11. Applied validity of effortless method for design of sinusoidal surface microstructure

    International Nuclear Information System (INIS)

    With the purpose of easily analyzing and designing the transmittance performance of a sinusoidal surface microstructure, the validity of effortless methods including scalar diffraction theory and effective medium theory has been evaluated quantitatively by the comparison of diffraction efficiencies predicted from scalar theory and effective indices theory, respectively, with exact results calculated with the rigorous vector method of Fourier modal method. Generally speaking, when the normalized period of surface microstructure is less than ten wavelengths of the incident light the scalar diffraction theory is believed to be inaccurate for designing and analyzing the diffraction efficiency of surface microstructure. But, in this paper, it is found that scalar diffraction theory can be used for predicting transmittance of the optical elements when the normalized period is more than three wavelengths of incident light within the error less than 5% at normal incidence. In addition, it is generally recognized that the effective medium theory is inaccurate for analyzing periodic surface microstructure when the normalized period is more than a tenth of the wavelength of incident light. However, the results in this study shows that effective medium theory is accurate as only zero-order waves are to propagate through the surface profiles, which the maximum difference between zero-order effective indices method and rigorous vector method reaches to 1%. Besides, the limitation of both simplified theories is dependent on not only the normalized period of a surface microstructure but also the normalized groove depth. Therefore, the range of applied validity of scalar theory and effective medium theory is expanded quantitatively compared to that of previous inaccuracy application for more easily designing and analyzing a sinusoidal surface microstructure.

    2012-12-01

    Over the course of 9 years, an international multidisciplinary team of US and Kenyan scientists under the Sustainable Management of Rural Watersheds (SUMAWA) Project, based at Egerton University in Kenya, worked with Kenyan public agencies to apply a variety of participatory methods and outreach activities combined with land use mapping, hydrologic and water system modeling, and other scientific tools and evaluations to investigate and identify solutions to declining water quantity and quality problems affecting communities and environmental and productive sectors in the River Njoro Watershed in Kenya. Traditional participatory rural appraisal techniques were modified to engage low income, informal, and tribal communities in identification of local services, benefits, and groups linked to water and riparian resources and collect their perceptions of water-related problems, priorities, and solution options throughout the watershed. Building on this foundation of insights, information, and engagement on water issues with local communities and other stakeholders, the project designed a research agenda aimed at creating shared scientific understanding of the causes of identified problems and developing and testing promising interventions to address community and stakeholder priority concerns. This presentation will share lessons from the SUMAWA experience of using a problem-driven, solution-oriented, community-based watershed approach to address water resource problems at local scale in a semi-arid African developing country setting.

    The FuturICT project seeks to use the power of big data, analytic models grounded in complexity science, and the collective intelligence they yield for societal benefit. Accordingly, this paper argues that these new tools should not remain the preserve of restricted government, scientific or corporate élites, but be opened up for societal engagement and critique. To democratise such assets as a public good, requires a sustainable ecosystem enabling different kinds of stakeholder in society, including but not limited to, citizens and advocacy groups, school and university students, policy analysts, scientists, software developers, journalists and politicians. Our working name for envisioning a sociotechnical infrastructure capable of engaging such a wide constituency is the Global Participatory Platform (GPP). We consider what it means to develop a GPP at the different levels of data, models and deliberation, motivating a framework for different stakeholders to find their ecological niches at different levels within the system, serving the functions of (i) sensing the environment in order to pool data, (ii) mining the resulting data for patterns in order to model the past/present/future, and (iii) sharing and contesting possible interpretations of what those models might mean, and in a policy context, possible decisions. A research objective is also to apply the concepts and tools of complexity science and social science to the project's own work. We therefore conceive the global participatory platform as a resilient, epistemic ecosystem, whose design will make it capable of self-organization and adaptation to a dynamic environment, and whose structure and contributions are themselves networks of stakeholders, challenges, issues, ideas and arguments whose structure and dynamics can be modelled and analysed.

  14. Empirical study on voting power in participatory forest planning.

    Multicriteria decision support systems are applied in natural resource management in order to clarify the planning process for the stakeholders, to make all available information usable and all objectives manageable. Especially when the public is involved in planning, the decision support system should be easy to comprehend, transparent and fair. Social choice theory has recently been applied to group decision-making in natural resources management to accomplish these objectives. Although voting forms the basis of democracy, and is usually taken as a fair method, the influence of voters over the outcome may vary. It is also possible to vote strategically to improve the results from each stakeholder's point of view. This study examines the use of social choice theory in revealing stakeholders' preferences in participatory forest planning, and the influence of different voters on the outcome. The positional voting rules examined were approval voting and Borda count, but both rules were slightly modified for the purposes of this study. The third rule examined, cumulative rule, resembles utilitarian voting rules. The voting rules were tested in a real participatory forest planning situation in eastern Lapland, Finland. All voting rules resulted in a different joint order of importance of the criteria. Yet, the preference orders produced had also a lot in common and the criteria could be divided into three quite distinct groups according to their importance. The influence of individual voters varied between the voting rules, and in each case different voter was the most influential. PMID:17395363

  15. Applying Software Engineering Methodology for Designing Biomedical Software Devoted To Electronic Instrumentation

    Directory of Open Access Journals (Sweden)

    Alderico Rodrigues de Paula Junior

    2012-01-01

    Full Text Available Problem statement: Significant effort goes into the development of biomedical software, which is integrated with computers/processors, sensors and electronic instrumentation devoted to a specific application. However, the scientific work on electronic instrumentation controlled by biomedical software has not emphasized software development, instead focusing mainly on electronics engineering. The development team is rarely composed of Software Engineering (SE experts. Usually, a commercial automated tools environment is not used due to its high cost and complexity for researchers from other areas to understand. Approach: This present study reports how the SE approach was applied to design and develop biomedical software, which is part of a Computerized Electronic Instrumentation (CEI. This CEI comprises software and an electronic instrumentation based on a force sensor and electrogoniometer to monitor the hand exertion of computer user during typing task. The aim is to serve as a guideline for academic researchers who are not expert in software engineering methodology but usually develop their own software to run with their CEI. The specification of the requirements, presented as use case, includes the context diagram, the data flow diagram, the entity relationship diagram and test procedure. The Unified Modelling Language from the Enterprise Architect tool was used. The developed software and the electronic instrumentation were tested together. Results: A sample of the interface screen shows how the outcomes could be plotted in an integrated manner. By comparing the values with other values obtained by manual calculations and with those provided by sensor manufacturer, the repeatability of test procedure validated the results. Reliable electronic instrumentation when working with unreliable software can become unreliable. Conclusion: Applying software engineering methodology principles provided a simple and clear documentation that was helpful

  3. Improving ethical and participatory practice for marginalized populations in biomedical HIV prevention trials: lessons from Thailand.

    Directory of Open Access Journals (Sweden)

    Dan Allman

    Full Text Available BACKGROUND: This paper presents findings from a qualitative investigation of ethical and participatory issues related to the conduct of biomedical HIV prevention trials among marginalized populations in Thailand. This research was deemed important to conduct, as several large-scale biomedical HIV prevention trials among marginalized populations had closed prematurely in other countries, and a better understanding of how to prevent similar trial closures from occurring in the future was desired. METHODS: In-depth key informant interviews were held in Bangkok and Chiang Mai, Thailand. Interviews were audio recorded, transcribed, translated and thematically analyzed. The Good Participatory Practice Guidelines for Biomedical HIV Prevention Trials (GPP guided this work. RESULTS: Fourteen interviews were conducted: 10 with policymakers, academic and community-based researchers and trial staff and four with representatives of non-governmental organizations (NGOs. Suggested ways to improve ethical and participatory practice centered on standards of HIV prevention, informed consent, communication and human rights. In particular, the need to overcome language and literacy differences was identified. Key informants felt communication was the basis of ethical understanding and trust within biomedical HIV prevention trial contexts, and thus fundamental to trial participants' ability to exercise free will. DISCUSSION: Biomedical HIV prevention trials present opportunities for inclusive and productive ethical and participatory practice. Key informants suggested that efforts to improve practice could result in better relationships between research stakeholders and research investigative teams and by extension, better, more ethical participatory trials. This research took place in Thailand and its findings apply primarily to Thailand. However, given the universality of many ethical considerations, the results of this study can inform the improvement of ethical

    The electromagnetic pump imposes the electromagnetic motive force (Lorentz force) on the liquid metal directly and makes it move along the definite direction by using the function of electric current and magnetic field in the conducting fluid.Compared with the traditional die casting, the system of counter-gravity casting can effectively control the speed of fillingto make Al-alloy liquid fill steadily by adjusting controlled-current. So the foundry defects can be decreased or avoided effectively by this system. Based on the theory of electromagnetic pump, the design method of electromagnetic field in electromagnetic pump was investigated emphatically. The rule of magnetic induction intensity B influenced by the divided electromagnet airgap's size was founded. Furthermore, the empirical formula of magnetic induction intensity B in a magnetic airgap for an open magnet in the saturated state was deduced by mathematics regression analysis. Counter-gravity casting applied to the Al-alloy electromagnetic filling was developed with this method. Besides, the electromagnetism filling counter-gravity casting process of the turbo-charge blade wheel was also fixed. The eligibility rate of blade wheel produced by such technique can be increased to 98%. The casts have compact structure and excellent capability.

    2010-01-01

    This Technical Publication (TP) is meant to address a number of topics related to the application of Monte Carlo simulation to launch vehicle design and requirements analysis. Although the focus is on a launch vehicle application, the methods may be applied to other complex systems as well. The TP is organized so that all the important topics are covered in the main text, and detailed derivations are in the appendices. The TP first introduces Monte Carlo simulation and the major topics to be discussed, including discussion of the input distributions for Monte Carlo runs, testing the simulation, how many runs are necessary for verification of requirements, what to do if results are desired for events that happen only rarely, and postprocessing, including analyzing any failed runs, examples of useful output products, and statistical information for generating desired results from the output data. Topics in the appendices include some tables for requirements verification, derivation of the number of runs required and generation of output probabilistic data with consumer risk included, derivation of launch vehicle models to include possible variations of assembled vehicles, minimization of a consumable to achieve a two-dimensional statistical result, recontact probability during staging, ensuring duplicated Monte Carlo random variations, and importance sampling.

    This work is focused on evaluation and effectiveness comparison of two different heuristic algorithms in context of hybrid model used for optimization of the pressurized water distribution systems: genetic algorithm (GA) and harmony search methodology (HS). The optimization of the water distribution system is a complex problem which involves determining the commercial diameter for each pipe in the network while satisfying the water demand and pressure at each node (least-cost design task). The optimal design is in this formulation of the problem the lowest cost design out of numerous possibilities. Hybrid models present a further step in this optimization task, by elimination of some disadvantages in its standard formulation where are heuristic methods applied usually alone (extensive fine-tuning, very big search space, no guarantee for global optimum especially in big problems, etc). In the proposed and described hybrid method two substantially different algorithmic techniques are employed - linear programming (LP) and heuristic algorithm (genetic algorithms or harmony search in this work). Authors put together the contribution each of these algorithms to common task in which best possibilities of each other are employed and disadvantages are eliminated (LP is not suitable for looped networks and heuristic methods do not guarantee global optimum). The GA or HS method is used in the outer loop of the proposed algorithm, which is intended for decomposing a complex looped network to a group of possible branched networks. The mathematical models using LP are then automatically set up in an inner loop for each selected (by GA or HS) member of this group of branched networks for their optimization. After evaluating the high number of possible branch networks (by LP which is nested in a GA or HS objective function), an optimal solution could be found for the original looped network. The advantage of using this hybrid method consists in the fact that GA or HS in this case

    Evaluating participatory decision processes serves two key purposes: validating the usefulness of specific interventions for stakeholders, interveners and funders of conflict management processes, and improving practice. However, evaluation design remains challenging, partly because when attempting to serve both purposes we may end up serving neither well. In fact, the better we respond to one, the less we may satisfy the other. Evaluations tend to focus on endogenous factors (e.g., stakeholder selection, BATNAs, mutually beneficial tradeoffs, quality of the intervention, etc.), because we believe that the success of participatory decision processes hinges on them, and they also seem to lend themselves to caeteris paribus statistical comparisons across cases. We argue that context matters too and that contextual differences among specific cases are meaningful enough to undermine conclusions derived solely from comparisons of process-endogenous factors implicitly rooted in the caeteris paribus assumption. We illustrate this argument with an environmental mediation case. We compare data collected about it through surveys geared toward comparability across cases to information elicited through in-depth interviews geared toward case specifics. The surveys, designed by the U.S. Institute of Environmental Conflict Resolution, feed a database of environmental conflicts that can help make the (statistical) case for intervention in environmental conflict management. Our interviews elicit case details - including context - that enable interveners to link context specifics and intervention actions to outcomes. We argue that neither approach can "serve both masters." PMID:24121657

    OBJECTIVES: The study objectives were to estimate the total costs incurred by a comprehensive review of primary health care services in a rural region in South Africa, and to determine which of these costs were incurred because of the participatory research techniques employed by the review. DESIGN: The costing study estimated the direct and indirect costs of each component of the review in order to determine total costs. Costs that were linked to participatory research activities were aggregated separately. SETTING: The review that was costed was conducted in an area that included the former 'homeland' KaNgwane and the adjacent areas of 'white' South Africa, in part of what is now known as Mpumalanga Province. SUBJECTS: Not relevant. OUTCOME MEASURES: Direct, indirect, total, research and participation costs were used as outcome measures. RESULTS: Expenditure generated by participatory research techniques was estimated to be almost 14% of the total (direct and indirect) costs. CONCLUSIONS: Despite these costs, participatory research techniques are invaluable in terms of the many benefits they have for a research project. However, because of these costs, it is important that the financing of participatory research should be carefully planned. Projects must budget for the direct costs of participatory techniques, participating organisations and individuals must be committed to bearing the indirect costs of participation, and, increasingly, funders must consider funding these indirect costs. This is important in the South African situation, where public health research relies increasingly on the participation of relevant stakeholders. PMID:9608312

    Full Text Available Transforming mature tourism resorts has evolved toward a greater involvement of public authorities and away from the mere renovation of public spaces. Authorities today are required to lead the reorganization of tourism activities through the development of co-operative networks between all stakeholders involved. In this paper, a participatory integrated approach has been designed and implemented in collaboration with Spanish authorities and the tourism sector to propose a strategy to achieve the renovation of tourism resorts. This methodology was applied to Puerto de la Cruz, the oldest tourism destination in the Canary Islands and a clear paradigm of a consolidated resort. The objective is to define and implement policies to transform Puerto de la Cruz into a more sustainable tourism destination.

    Full Text Available Participatory research has in recent years become a popular approach for problem-oriented scientific research that aims to tackle complex problems in a real management context. Within the European Union project NeWater, stakeholder processes were initiated in seven case studies to develop approaches for adaptive water management. The Uzbek part of the Amudarya River basin was one of the studied river basins. However, given the current political and cultural context in Uzbekistan, which provides little room for stakeholder participation, it was unclear to what extent participation could be realized there. In this paper, we present an evaluation of the participatory research carried out in the Amudarya case study with respect to (i the choice and application of different participatory methods and their adaptation to the given political, socioeconomic, and cultural environment, (ii their usefulness in improving system understanding and developing strategies and measures to improve water management and monitoring, and (iii their acceptance and suitability for enhancing policy-making processes in the Amudarya River basin context. The main lessons learned from the comparison of the different participatory methods were (1 the stakeholder process provided an opportunity for meetings and discussions among stakeholders from different organizational levels and thus promoted communication between different levels and organizations, and (2 in a context where most stakeholders are not generally involved in policy-making, there is a danger of raising expectations that a research project cannot meet, e.g., of transferring local interests to higher levels. Our experience shows that in order to choose participatory methods and adapt them to the Uzbek cultural and political setting (and most likely this applies to other post-Soviet transition countries as well, four aspects should be taken into account: the time required to prepare and apply the method, good

    Background Limpopo Province is one of the hardest hit by tuberculosis and human immune virus infections in the country. The province has been implementing a directly observed treatment strategy since 1996. However, the cure rate was 64% in 2015 and remains far from the set target by the World Health Organization of 85%. Poor health-care seeking and adherence behaviours were identified as major risk behaviours. Aim To apply a Community-Based Participatory Research (CBPR) approach in identifying barriers and facilitators to health-care seeking and adherence to treatment, and to determine strategies and messages in order to inform the design of an adapted intervention programme. Setting This study was conducted in three districts in the Limpopo Province, Capricorn, Mopani and Sekhukhune districts. Methods The community participatory research approach was applied. Purposive sampling was used to sample participants. Focus group discussions were used to collect data. Participatory analysis was used comparing findings within and across all the participants. Results A total of 161 participated in the study. Participants included coordinators, professional nurses, supporters and patients. Major modifiable behavioural-related barriers were lack of knowledge about tuberculosis, misinformation and misperceptions cultural beliefs, stigma and refusal of treatment support. Environment-related barriers were attitudes of health workers, lack of support by family and community, lack of food and use of alcohol and drugs. Strategies and messages included persuasive and motivational messages to promote healthy behaviour. Conclusion Joint programmatic collaboration between the community and academic researchers is really needed for interventions to address the needs of the community.

  2. Optimization methods applied to the aerodynamic design of helicopter rotor blades

    Walsh, Joanne L.; Bingham, Gene J.; Riley, Michael F.

    1987-01-01

    Described is a formal optimization procedure for helicopter rotor blade design which minimizes hover horsepower while assuring satisfactory forward flight performance. The approach is to couple hover and forward flight analysis programs with a general-purpose optimization procedure. The resulting optimization system provides a systematic evaluation of the rotor blade design variables and their interaction, thus reducing the time and cost of designing advanced rotor blades. The paper discusses the basis for and details of the overall procedure, describes the generation of advanced blade designs for representative Army helicopters, and compares design and design effort with those from the conventional approach which is based on parametric studies and extensive cross-plots.

    Full Text Available Abstract Participatory scenario processes are associated with positive social learning outcomes, including consensus-building and shifts toward more systemic thinking. However, these claims have not been assessed quantitatively in diverse cultural and socio-ecological settings. We convened three stakeholder workshops around the future of agricultural development and rural livelihoods in Burkina Faso, Nigeria, and Malawi, using a participatory scenario generation process to examine proposed research and action priorities under conditions of uncertainty. We administered pre- and post-workshop surveys, and used a paired t-test to assess how stakeholders’ rankings of research priorities changed after participating in the scenario visioning exercise. Workshop participants also listed their own priorities for research and implementation on both the pre- and post-survey forms. We found indications that the workshops promoted consensus-building around the research priorities, including a reduction in standard deviation of priority rankings post-workshop compared to pre-workshop; and a higher incidence of identical volunteered responses. We did not find evidence to support shifts in thinking to more systemic views of agricultural development. However, participants viewed themselves as having learned throughout the process. We conclude that scenario visioning does have the potential to foster consensus-building (one element of social learning among diverse stakeholder groups. We urge researchers to continue to monitor and measure systems thinking outcomes from scenario visioning so that these processes may be designed to be more effective.

    A participatory strategies approach which involves employees in the planning and delivery of worksite health promotion programs was utilized in the 55 experimental worksites included in the national, NCI-funded Working Well Trial. According to study protocol, Employee Advisory Boards (EABs) were organized in each experimental worksite. This paper describes two substudies designed to develop and measure participatory strategies associated with the EABs in the Working Well Trial. Study 1 determined characteristics of the EABs, developed subscales and assessed the internal consistency of the scales. Study 2 used a confirmatory factor analysis to examine the structure of the developed questionnaire. The four subscales include: Autonomy/Independence, Management Involvement, Institutionalization/Commitment and Others Involvement. Results from Study 1 indicate that the four subscales of the 24-item instrument demonstrated strong internal consistency and three were sensitive enough to register differences by Study Center at the baseline. Study 2 results found that the EAB subscales again demonstrated good internal consistency, structural stability and acceptable sensitivity. An initial validity analysis was performed and yielded results which supported some but not all of the hypothesized associations. Implications for further refinement and application of this new instrument in worksite settings are explored. PMID:10539228

  7. Shark, new motor design concept for energy saving applied to switched reluctance motor

    Energy Technology Data Exchange (ETDEWEB)

    Tataru Kjaer, A.M.

    2005-07-01

    The aim of this thesis is to document and promote a relatively new concept of designing electrical machine with improved efficiency, without using more or better material. The concept, called Shark, consists in replacing the cylindrical air gap by a non-linear shape obtained by translating specific geometrical pattern on the longitudinal axis of the electrical machine. This shape modification increases the air gap area and thus the energy conversion, taking place in the machine. Whilst other methods of improving the efficiency consider the use of more and/or better magnetic material and/or optimisation of the magnetic circuit of the radial cross-section of the machine, the proposed method makes use of the longitudinal cross-section of the machine. In spite of a few reports claiming the improvement of the efficiency by applying the optimisation of the longitudinal cross-section, none analysis of various air gap shapes and of their influence on the magnetic performance has been reported. Due to a simple geometry, the Switched Reluctance Machine has been selected for demonstration of the Shark principle. Initially, linear and finite element analyses are considered. They provide the basic knowledge of the manner in which various Shark air gap, having different dimensions, influence the energy conversion in the machine. The saturation mechanisms, specific to each Shark profile are analysed and optimum Shark profile and its dimensions are selected for implementation in a demonstration machine. Due to the lack of quick analysis tools, an analytical model of the Shark Switched Reluctance Machine is also proposed in this thesis. This model is conceived by modifying one of the existing models of cylindrical air gap Switched Reluctance Machines, such as to account for the presence of the Shark profiles in the air gap. The calculations are verified by measurement on two demonstration machines, having cylindrical and Shark air gaps. The measurement proved the theory right and

    According to Messages from the Bonn2011 Conference, involving local communities fully and effectively in the planning and implementation processes related to water, energy and food nexus for local ownership and commitment should be strongly needed. The participatory approaches such as deliberative polling, "joint fact-finding" and so on have been applied so far to resolve various environmental disputes, however the drivers and barriers in such processes have not been necessarily enough analyzed in a comprehensive manner, especially in Japan. Our research aims to explore solutions for conflicts in the context of water-energy-food nexus in local communities. To achieve it, we clarify drivers and barriers of each approaches applied so far in water, energy and food policy, focusing on how to deal with scientific facts. We generate hypotheses primarily that multi-issue solutions through policy integration will be more effective for conflicts in the context of water-energy-food nexus than single issue solutions for each policy. One of the key factors to formulate effective solutions is to integrate "scientific fact (expert knowledge)" and "local knowledge". Given this primary hypothesis, more specifically, we assume that it is effective for building consensus to provide opportunities to resolve the disagreement of "framing" that stakeholders can offer experts the points for providing scientific facts and that experts can get common understanding of scientific facts in the early stage of the process. To verify the hypotheses, we develop a database of the cases which such participatory approaches have been applied so far to resolve various environmental disputes based on literature survey of journal articles and public documents of Japanese cases. At present, our database is constructing. But it's estimated that conditions of framing and providing scientific information are important driving factors for problem solving and consensus building. And it's important to refine

    Vaccinomics is the convergence of vaccinology and population-based omics sciences. The success of knowledge-based innovations such as vaccinomics is not only contingent on access to new biotechnologies. It also requires new ways of governance of science, knowledge production, and management. This article presents a conceptual analysis of the anticipatory and adaptive approaches that are crucial for the responsible design and sustainable transition of vaccinomics to public health practice. Anticipatory governance is a new approach to manage the uncertainties embedded on an innovation trajectory with participatory foresight, in order to devise governance instruments for collective "steering" of science and technology. As a contrast to hitherto narrowly framed "downstream impact assessments" for emerging technologies, anticipatory governance adopts a broader and interventionist approach that recognizes the social construction of technology design and innovation. It includes in its process explicit mechanisms to understand the factors upstream to the innovation trajectory such as deliberation and cocultivation of the aims, motives, funding, design, and direction of science and technology, both by experts and publics. This upstream shift from a consumer "product uptake" focus to "participatory technology design" on the innovation trajectory is an appropriately radical and necessary departure in the field of technology assessment, especially given that considerable public funds are dedicated to innovations. Recent examples of demands by research funding agencies to anticipate the broad impacts of proposed research--at a very upstream stage at the time of research funding application--suggest that anticipatory governance with foresight may be one way how postgenomics scientific practice might transform in the future toward responsible innovation. Moreover, the present context of knowledge production in vaccinomics is such that policy making for vaccines of the 21st

    Full Text Available BACKGROUND: This study aims to promote occupational health in the informal sector in Thailand by using a participatory approach. The success of the intervention is based on an evaluation of the informal sector workers' a knowledge, attitudes, and behaviors in occupational health and safety, b work practice improvement, and c working condition improvement. METHODS: This study applies the Participatory Action Research (PAR method. The participants of the study consisted of four local occupations in different regions of Thailand, including a ceramic making group in the North, a plastic weaving group in the Central region, a blanket making group in the Northeast, and a pandanus weaving group in the South. Data was collected using both qualitative and quantitative methods through questionnaires, industrial hygiene instruments, and group discussions. RESULTS: The results showed that the working conditions of the informal sector were improved to meet necessary standards after completing the participatory process. Also, the post-test average scores on 1 the occupational health and safety knowledge, attitudes and behaviors measures and 2 the work practice improvement measures were significantly higher than the pre-test average scores (p=sig. CONCLUSIONS: The results demonstrate that the participatory approach is an effective tool to use when promoting the health safety of the informal sector and when encouraging the workers to voluntarily improve the quality of their own lives.

    2012-01-01

    Full Text Available Since the nineties, participatory planning has emerged as a linking strategy for various social, political, economic and cultural sectors that assessed it as a potential for building consensus in the making of local processes forsocial improvement. Similarly, it was legitimized as a setting for practice for professionals trained in the social sciences, mainly Social Work. This article, from a geopolitical and geo-cultural perspective, presents contextual elements that determined the configuration of participatory planning in Latin America. These elements shall be staged in order to redefine diversity and the intercultural perspective that has been linked to this mobilizing strategy, against the institutionalized discourse of development and for the emergence of crisis and ruptures with this social paradigm from other practices and worldviews of life in the territories.

    2012-11-01

    Full Text Available The conceptions of participatory phenomenon are wide and generate various positions. Several authors agree that municipal government, as the face of the State closer to its citizens, is the privileged place to develop participatory public policies, which contributes to make more transparent, efficient, inclusive and democratic the government management. This proximity would allow local actors to participate in communal development processes and would enable them to diagnose problems, participating in decision-making and public policies designing and its evaluation. Moreover, it is noticed that the State transfer its duties to the society through manipulation of participatory policies, which are used as artificial means to build consensus. This article explores the fundamentals, implementation methodologies and results in four cases of participatory budgeting (in La Plata, San Fernando, San Miguel and San Martín. The main lines of analysis focused on the characterization of the projects generated by this policy, the changes in local management and the type of social participation. This research used semi structured and in depth interviews, observations, documentary research with secondary sources of information generated by municipalities (website, laws, institutional documentation, brochures, statistics and academic works produced by other researchers.

  14. Decomposition with Thermoeconomic Isolation Applied to the Optimal Synthesis/Design of an Advanced Tactical Aircraft System

    Directory of Open Access Journals (Sweden)

    Michael R. von Spakovsky

    2003-09-01

    Full Text Available A decomposition methodology based on the concept of “thermoeconomic isolation” and applied to the synthesis/design and operational optimization of an advanced tactical fighter aircraft is the focus of this paper. The most promising set of aircraft sub-system configurations, based on both an energy integration analysis and aerodynamic performance, were first developed and detailed thermodynamic, geometric, physical, and aerodynamic models at both design and off-design were formulated and implemented. Conceptual, time, and physical decomposition were then applied to the synthesis/design and operational optimization of the aircraft system. The physical decomposition strategy used, called Iterative Local-Global Optimization (ILGO, was developed by Muñoz and von Spakovsky (2001a,b and has been applied to a number of complex stationary and transportation applications. This decomposition strategy is the first to successfully closely approach the theoretical condition of “thermoeconomic isolation” when applied to highly complex, highly dynamic non-linear systems.

  18. Investigating Geosparql Requirements for Participatory Urban Planning

    Science.gov (United States)

    Mohammadi, E.; Hunter, A. J. S.

    2015-06-01

    We propose that participatory GIS (PGIS) activities including participatory urban planning can be made more efficient and effective if spatial reasoning rules are integrated with PGIS tools to simplify engagement for public contributors. Spatial reasoning is used to describe relationships between spatial entities. These relationships can be evaluated quantitatively or qualitatively using geometrical algorithms, ontological relations, and topological methods. Semantic web services utilize tools and methods that can facilitate spatial reasoning. GeoSPARQL, introduced by OGC, is a spatial reasoning standard used to make declarations about entities (graphical contributions) that take the form of a subject-predicate-object triple or statement. GeoSPARQL uses three basic methods to infer topological relationships between spatial entities, including: OGC's simple feature topology, RCC8, and the DE-9IM model. While these methods are comprehensive in their ability to define topological relationships between spatial entities, they are often inadequate for defining complex relationships that exist in the spatial realm. Particularly relationships between urban entities, such as those between a bus route, the collection of associated bus stops and their overall surroundings as an urban planning pattern. In this paper we investigate common qualitative spatial reasoning methods as a preliminary step to enhancing the capabilities of GeoSPARQL in an online participatory GIS framework in which reasoning is used to validate plans based on standard patterns that can be found in an efficient/effective urban environment.

    2015-01-01

    Cell-based potency assays play an important role in the characterization of biopharmaceuticals but they can be challenging to develop in part because of greater inherent variability than other analytical methods. Our objective is to select concentrations on a dose-response curve that will enhance assay robustness. We apply the maximin D-optimal design concept to the four-parameter logistic (4 PL) model and then derive and compute the maximin D-optimal design for a challenging bioassay using curves representative of assay variation. The selected concentration points from this 'best worst case' design adequately fit a variety of 4 PL shapes and demonstrate improved robustness. PMID:26235135

  2. A General Multidisciplinary Turbomachinery Design Optimization system Applied to a Transonic Fan

    Science.gov (United States)

    Nemnem, Ahmed Mohamed Farid

    The blade geometry design process is integral to the development and advancement of compressors and turbines in gas generators or aeroengines. A new airfoil section design capability has been added to an open source parametric 3D blade design tool. Curvature of the meanline is controlled using B-splines to create the airfoils. The curvature is analytically integrated to derive the angles and the meanline is obtained by integrating the angles. A smooth thickness distribution is then added to the airfoil to guarantee a smooth shape while maintaining a prescribed thickness distribution. A leading edge B-spline definition has also been implemented to achieve customized airfoil leading edges which guarantees smoothness with parametric eccentricity and droop. An automated turbomachinery design and optimization system has been created. An existing splittered transonic fan is used as a test and reference case. This design was more general than a conventional design to have access to the other design methodology. The whole mechanical and aerodynamic design loops are automated for the optimization process. The flow path and the geometrical properties of the rotor are initially created using the axi-symmetric design and analysis code (T-AXI). The main and splitter blades are parametrically designed with the created geometry builder (3DBGB) using the new added features (curvature technique). The solid model creation of the rotor sector with a periodic boundaries combining the main blade and splitter is done using MATLAB code directly connected to SolidWorks including the hub, fillets and tip clearance. A mechanical optimization is performed with DAKOTA (developed by DOE) to reduce the mass of the blades while keeping maximum stress as a constraint with a safety factor. A Genetic algorithm followed by Numerical Gradient optimization strategies are used in the mechanical optimization. The splittered transonic fan blades mass is reduced by 2.6% while constraining the maximum

    2016-03-01

    Product customization is a trend in the current market-oriented manufacturing environment. However, deduction from customer requirements to design results and evaluation of design alternatives are still heavily reliant on the designer's experience and knowledge. To solve the problem of fuzziness and uncertainty of customer requirements in product configuration, an analysis method based on the grey rough model is presented. The customer requirements can be converted into technical characteristics effectively. In addition, an optimization decision model for product planning is established to help the enterprises select the key technical characteristics under the constraints of cost and time to serve the customer to maximal satisfaction. A new case retrieval approach that combines the self-organizing map and fuzzy similarity priority ratio method is proposed in case-based design. The self-organizing map can reduce the retrieval range and increase the retrieval efficiency, and the fuzzy similarity priority ratio method can evaluate the similarity of cases comprehensively. To ensure that the final case has the best overall performance, an evaluation method of similar cases based on grey correlation analysis is proposed to evaluate similar cases to select the most suitable case. Furthermore, a computer-aided system is developed using MATLAB GUI to assist the product configuration design. The actual example and result on an ETC series machine tool product show that the proposed method is effective, rapid and accurate in the process of product configuration. The proposed methodology provides a detailed instruction for the product configuration design oriented to customer requirements.

  12. Applying Human Factors Evaluation and Design Guidance to a Nuclear Power Plant Digital Control System

    Energy Technology Data Exchange (ETDEWEB)

    2012-08-01

    The United States (U.S.) nuclear industry, like similar process control industries, has moved toward upgrading its control rooms. The upgraded control rooms typically feature digital control system (DCS) displays embedded in the panels. These displays gather information from the system and represent that information on a single display surface. In this manner, the DCS combines many previously separate analog indicators and controls into a single digital display, whereby the operators can toggle between multiple windows to monitor and control different aspects of the plant. The design of the DCS depends on the function of the system it monitors, but revolves around presenting the information most germane to an operator at any point in time. DCSs require a carefully designed human system interface. This report centers on redesigning existing DCS displays for an example chemical volume control system (CVCS) at a U.S. nuclear power plant. The crucial nature of the CVCS, which controls coolant levels and boration in the primary system, requires a thorough human factors evaluation of its supporting DCS. The initial digital controls being developed for the DCSs tend to directly mimic the former analog controls. There are, however, unique operator interactions with a digital vs. analog interface, and the differences have not always been carefully factored in the translation of an analog interface to a replacement DCS. To ensure safety, efficiency, and usability of the emerging DCSs, a human factors usability evaluation was conducted on a CVCS DCS currently being used and refined at an existing U.S. nuclear power plant. Subject matter experts from process control engineering, software development, and human factors evaluated the DCS displays to document potential usability issues and propose design recommendations. The evaluation yielded 167 potential usability issues with the DCS. These issues should not be considered operator performance problems but rather opportunities

    Paynter, C.; Cuchanski, M.

    1995-01-01

    The paper discusses various aspects of the system design for a satellite in a highly elliptical inclined orbit, and presents a number of antenna design options for the proposed Archimedes mission. A satellite constellation was studied for the provision of multi media communication services in the L and S Band for northern latitudes. The inclined elliptical orbit would allow coverage of Europe, America, and East Asia. Using Canada and North America as the baseline coverage area, this paper addresses system considerations such as the satellite configuration and pointing, beam configuration, and requirements for antennas. A trade-off is performed among several antenna candidates including a direct radiating array, a focal-fed reflector, and a single reflector imaging system. Antenna geometry, performance, and beam forming methods are described. The impact of the designs on the antenna deployment is discussed.

    2003-12-01

    Although much social science research has been conducted within American Indian and Alaska Native (AIAN) communities, relatively little research has been conducted by or for those communities. We describe an approach that facilitates the active involvement of AIAN communities in the research process, from conceptualizing the issues to be investigated to developing a research design, and from collecting, analyzing, and interpreting the data to disseminating the results. The Tribal Participatory Research (TPR) approach is consistent with recent developments in psychology that emphasize the inclusion of community members and the social construction of knowledge. We describe the foundations of the approach and present specific mechanisms that can be employed in collaborations between researchers and AIAN communities. We conclude with a discussion of the implications of the use of TPR regarding project timelines and budgets, interpretation of the data, and ultimately the relationships between tribes and researchers.

    Hale, Joseph P.

    1997-01-01

    Application of Virtual Reality (VR) technology offers much promise to enhance and accelerate the development of Reusable Launch Vehicle (RLV) infrastructure and operations while simultaneously reducing developmental and operational costs. One of the primary cost areas in the RLV concept that is receiving special attention is maintenance and refurbishment operations. To produce and operate a cost effective RLV, turnaround cost must be minimized. Designing for maintainability is a necessary requirement in developing RLVs. VR can provide cost effective methods to design and evaluate components and systems for maintenance and refurbishment operations. The National Aeronautics and Space Administration (NASA)/Marshall Space Flight Center (MSFC) is beginning to utilize VR for design, operations development, and design analysis for RLVs. A VR applications program has been under development at NASA/MSFC since 1989. The objectives of the MSFC VR Applications Program are to develop, assess, validate, and utilize VR in hardware development, operations development and support, mission operations training and science training. The NASA/MSFC VR capability has also been utilized in several applications. These include: 1) the assessment of the design of the late Space Station Freedom Payload Control Area (PCA), the control room from which onboard payload operations are managed; 2) a viewing analysis of the Tethered Satellite System's (TSS) "end-of-reel" tether marking options; 3) development of a virtual mockup of the International Space Welding Experiment for science viewing analyses from the Shuttle Remote Manipulator System elbow camera and as a trainer for ground controllers; and 4) teleoperations using VR. This presentation will give a general overview of the MSFC VR Applications Program and describe the use of VR in design analyses, operations development, and training for RLVs.

  3. An Applied Method for Designing Maximally Decimating Non-uniform Filter Banks

    Institute of Scientific and Technical Information of China (English)

    2003-01-01

    Assembling individual line phase filters to form a multi-channel filter bank allows the synthesis filter to be similar to corresponding analysis filters, and the design calculation can be simple. The appropriate relations between synthesis filters and analysis filters eliminate most aliasing resulting from decimation in non-uniform maximally decimating filter banks, and LS algorithm and Remez algorithm are used to optimize the composite character. This design method can achieve approximate Perfect-Reconstruction. An example is given in which the general parameter filters with approximate line phase are used as units of a filter bank.

    1996-01-01

    Thermodynamic Vent System (TVS) and Multilayer Insulation (MLI) technology, originally developed for long term storage of cryogen propellants in microgravity, is ideally suited for propellant storage and delivery systems for solar thermal propulsion. With this technology the heat-induced pressure rise in the tank provides the propellant delivery pressure without the need for an auxiliary pressurant system, and propellant delivery is used to remove the excess heat to control tank pressure. The factors to consider in designing such a balanced system, are presented. An example of a minimum system design is presented along with examples of laboratory-tested hardware.

    Full Text Available Este trabalho objetiva relatar o emprego do enfoque qualitativo-participativo, bem como discutir seus fundamentos e potencialidades, tomando como base a participação dos autores na segunda avaliação externa do Programa de Treinamento em Epidemiologia Aplicada aos Serviços do Sistema Único de Saúde - EPISUS. Finalizada em outubro de 2007, em parceria com a Secretaria de Vigilância em Saúde e o Center for Diseases Control (CDC/Atlanta, a referida avaliação incorporou o enfoque da chamada quarta geração (fourth generation evaluation, no qual os avaliadores operam como mediadores, substituindo, assim, os fundamentos do enfoque tradicional antes utilizado. Para tanto, tornou-se necessária uma demarcação conceitual referente aos conceitos avaliação, qualitativo e participativo que orientariam o processo avaliativo focalizado. Quanto ao conceito avaliação, sua natureza conflui para as propostas de quarta geração e, portanto, transita de um caráter punitivo para um caráter construtivo. A dimensão participativa aponta para diferentes sentidos do que seja participar e, na experiência aqui relatada, adotou-se o sentido decisório, onde se busca reverter assimetrias de poder. O qualitativo é concebido na interface com a subjetividade, referindo-se a informações que não se submetem à quantificação. Tal modelo permitiu desvelar aspectos que, muitas vezes, se ocultam nos números e nas generalizações abstratas, tornando possível focalizar as relações que constituem o cotidiano dos programas e práticas em saúde, subsidiando, assim, sua transformação.This paper aims to present the authors' experience concerning the use of the qualitative-participatory approach in the second external evaluation of the Training Program in Epidemiology Applied to the Services of the National Health System - EPISUS.

    Shapiro, Ester R

    This article applies transdisciplinary approaches to critical health education for gender equity by analyzing textual and political strategies translating/culturally adapting the U.S. feminist health text, Our Bodies Ourselves (OBOS), for Latin American/Caribbean and U.S. Latina women. The resulting text, Nuestros Cuerpos, Nuestras Vidas (NCNV), was revised at multiple levels to reflect different cultural\\sociopolitical assumptions connecting individual knowledge, community-based and transnational activist organizations, and strategic social change. Translation/cultural adaptation decisions were designed to ensure that gender-equitable health promotion education crossed cultural borders, conveying personal knowledge and motivating individual actions while also inspiring participation in partnerships for change. Transdisciplinary approaches integrating critical ecosystemic frameworks and participatory methods can help design health promotion education mobilizing engaged, gender-equitable health citizenship supporting both personal and societal change.

    International Nuclear Information System (INIS)

    Highlights: • Simultaneous synthesis, design and operation of fermentation networks are addressed. • A superstructure NLP model is presented. • Ethanol production from molasses and hydrolyzed sugar cane bagasse is proposed. • Different tradeoffs between design and operating variables can be evaluated. - Abstract: In the present work, the optimal design of pre-fermentation and fermentation operations for ethanol production is obtained developing a superstructure mathematical model. Different configurations of both operations are simultaneously considered in an overall model which also includes detailed kinetics equations. The zero wait is the transfer policy selected for these stages for ensuring the quality of these operations, given the nature and characteristics of microbiological sugary substrates. From the overall proposed model, the optimal configuration of the stages, the number of duplicated units in each stage, the size of each process unit, the process variables as concentrations and flows, and the total investment and production cost are obtained. This model is formulated as a non-linear programming problem, which is solved by the Professional Software, General Algebraic Modeling System (GAMS) with the application of CONOPT solver. The optimal design and operation of pre-fermentation and fermentation stages are obtained and the attained results are compared with the structures in conventional distillery

    2015-01-01

    Formulas for evaluating the relative internal efficiencies of turbines that have not been designed as yet are given in many publications. Such assessments are required at the first stages of development and calculation of the thermal process circuit of a new steam turbine unit. The above-mentioned formulas are given without indicating the author's name, particular initial material, and evaluation accuracy. To give an answer on these questions, the relevant publications were analyzed, and the results from calculations of relative internal efficiencies carried out using the published formulas and obtained from the hs diagrams of already designed turbines are compared. It is determined that Professor B.M. Troyanovskii, a well-known scientist specializing in turbines, is the author of these formulas. It is shown that these formulas give the "upper" (the best) estimate of efficiency. Formulas having the same structure as those of Troyanovskii but yielding a mean estimate with respect to already designed turbines are proposed. The results from the performed comparison are aimed at helping the developers of thermal process circuits for new steam turbine units to select the values of relative internal efficiencies of the cylinders for a turbine that has not been designed as yet.

  14. Cost-effective Sampling Design Applied to Large-scale Monitoring of Boreal Birds

    Directory of Open Access Journals (Sweden)

    Fiona Schmiegelow

    2002-12-01

    Full Text Available Despite their important roles in biodiversity conservation, large-scale ecological monitoring programs are scarce, in large part due to the difficulty of achieving an effective design under fiscal constraints. Using long-term avian monitoring in the boreal forest of Alberta, Canada as an example, we present a methodology that uses power analysis, statistical modeling, and partial derivatives to identify cost-effective sampling strategies for ecological monitoring programs. Empirical parameter estimates were used in simulations that estimated the power of sampling designs to detect trend in a variety of species’ populations and community metrics. The ability to detect trend with increased sample effort depended on the monitoring target’s variability and how effort was allocated to sampling parameters. Power estimates were used to develop nonlinear models of the relationship between sample effort and power. A cost model was also developed, and partial derivatives of the power and cost models were evaluated to identify two cost-effective avian sampling strategies. For decreasing sample error, sampling multiple plots at a site is preferable to multiple within-year visits to the site, and many sites should be sampled relatively infrequently rather than sampling few sites frequently, although the importance of frequent sampling increases for variable targets. We end by stressing the need for long-term, spatially extensive data for additional taxa, and by introducing optimal design as an alternative to power analysis for the evaluation of ecological monitoring program designs.

    Full Text Available In the past, philosophy of education and curriculum designing focused on specialization and single disciplinarity approach .But since the turn of the 20th century, by a vast literature of realizing real and new educational needs and competencies beyond a single discipline, and criticizing the limits of that narrow approach to the reality, defining integrated curriculum or non-disciplinarity approaches has been a topic of discussion .Over the last decades, theorists offered six basic categories for non-disciplinary works :Parallel Disciplinary Approach, Interdisciplinary Approach, Multi-Disciplinary Approach, Cross-Disciplinary Approach, Plural-Disciplinary Approach and Supra/Trans-Disciplinary Approach. Through these approaches, integration seemed to be a matter of degree and method from fundamentally different starting points. Economics also is essentially an integrated discipline from different social sciences, mathematics, economic subjects, knowledge and ideas, and even methodology of natural sciences, and inevitably, its curriculum, educational programs and courses can not be designed unless benefited from these literature and approaches in the curriculum designing subject area. The present article briefly defines the non-disciplinarity approaches and shows their implications, applications and theoretical capacity in designing different possible curriculum and graduate educational courses in Economics.

    Full Text Available RoboCup is an international competition to prompted robotics and related subject like: Artificial intelligence, Image processing, control, devise design and etc. One of the subjects in RoboCup competitions is Soccer. Naturally robotic soccer is an interactive and complex procedure. it might be so idealistic, but some consider a challenge with a real human football team in 2050 , as the final goal of robotic soccer. There are several classes in robotic football matches such as: Middle size, Small size, simulation and so on. One of the most essential parts of a soccer robot in Middle size and Small size classes in the kicking system, this system is in charge of kicking the ball upon the command issued by the processor of robot. Almost every team develops their own unique shooting device. There are three main approaches to design and implement the robot kicking system. In this paper we designed and developed multi power kicking system that enables loop and vary shooting power. To design a good solenoid and to obtain maximum velocity of ball some parameters like: inductance, response time, resistance, force, dimensions and core-material should be balanced carefully. We used a DC-DC converter (Boost regulator for getting different currents to have different power of shooting. We are going to review the advantages of all of those approaches. Next we are purposes a novel Solenoid-based kicking system which has already been successfully implemented in Adro RoboCup team.

    2005-01-01

    The European Union Water Framework Directive (WFD) offers an unparalleled opportunity for improving river basin management. Active participation is essential for its delivery. "End-of-pipe" solutions will not deliver the improvements needed to achieve its ambitious goals. This research tested DesignWays, a toolkit for participatory planning, as a mechanism for maximizing the long-term social and environmental benefits of such stakeholder and community participation. It examined the emerging role of "planning for sustainability" in the context of river catchments. Sustainable management of water requires integration, and recognition of interconnections between systems at different levels of scale. This is an endeavour in which systems thinking provides useful tools. The development of DesignWays was a conscious attempt to embed 'new paradigm' living systems metaphors into a practical planning tool. This paper begins with a description of DesignWays and its development in Southern Africa. An outline of the context of the action research in North-West England is followed by a description of the stages of the process, with highlights of the outcomes. This research had two major outcomes: a contribution to theory through an in-depth exploration of the theoretical basis of participatory, ecologically informed design; and a contribution to practice through investigating DesignWays' potential to meet key challenges of the WFD. This research points to the importance of understanding participatory planning as a societal process, aiming to make the process engaging and meaningful. It has pointed to the need to see participatory planning and education for sustainability as an integrated process. It demonstrated the benefits of an iterative process in which planning at the landscape level of scale informs, and is informed by, work at the site level. It has shown that an approach consistent with a living systems paradigm can contribute to the development of more integrated

    Participatory GIS (PGIS) has been prescribed by scholars who sought to find a means to enable more equitable access to GIS data, diversifying the types of knowledge captured by a GIS and re-engineering GIS software. The popularity of PGIS is evident in the various studies and contexts in which it has been utilised. These include studies in risk assessment, land administration, resource management, crime mapping and urban design to mention but a few. Despite the popularity of PGIS as a body of research, little has been done in the analysis of the quality of PGIS information. The study investigated the use of data quality criteria commonly used in traditional GIS systems and shows that it is possible to apply the criteria used in traditional GIS to PGIS. It provides a starting point for PGIS studies to assess the quality of the product. Notably, this a reflective exercise on one case study, but the methodologies used in this study have been replicated in many others undertaken by Community Based Organisations as well as Non-Governmental Organisations. Therefore the findings are relevant to such projects.

  2. Experimental design of mixture applied to study PVP hydrogels properties crosslinked by ionizing radiation

    International Nuclear Information System (INIS)

    Hydrogels are three dimensional hydrophilic crosslinked polymeric networks that have capacity to swell by absorbing water or biological fluids without dissolve. Hydrogels have been widely used in different application fields from agriculture, industry and in biomedicine. The properties of a hydrogel are extremely important in selecting which materials are suitable for a specific application. So mixtures can offer hydrogels with different properties to different applications. The PVP hydrogels were prepared by gamma radiation of an aqueous polymer solution and crosslinked by gamma ray, an effective and simple method for hydrogel formation that offers some advantages over the other techniques. In this work, a mixture experimental design was used to study the relationship between polymer cross-linking and swelling properties of PVP hydrogels with PEG as plasticizer and agar as gellifier. The gel fraction was measured for every mixture specified for the experiment D-optimal designs. (author)

    Directory of Open Access Journals (Sweden)

    C. Castro*, C. Lozano**, F. Palacios*** and E. Zuazua****

    2009-01-01

    Full Text Available A continuous adjoint approach to aerodynamic design for viscous compressible flows on unstructuredgrids is developed, and three important problems raised in the continuous adjoint literature are solved. First, using tools of shape deformation of boundary integrals a generic adjoint formulation is developed withindependence of the kind of mesh used. Then, a systematic way of reducing the 2nd order derivative terms which arise is presented which avoids the need of using higher order numerical solvers to obtain accurateapproximations of the 2nd order derivatives. And finally, the class of admissible optimization functionals isclarified. Several remarks are made concerning the longstanding discrete vs. continuous adjoint dichotomy, with the emphasis not on the advantages or disadvantages of each method, but rather on the well-posedness of the approaches. The accuracy of the sensitivity derivatives is assessed by comparison with finite-difference computations, and the validity of the overall methodology is illustrated with design examples under demanding subsonic conditions.

    Full Text Available What language should be featured in assessment standards for international students? Have universities adjusted their assessment methods sufficiently to match the increased demand for studying abroad? How might art and design benefit from a more stable definition of standards? These are some questions this paper seeks to address by reporting the results of recent pedagogic research at the School of the Arts, Loughborough University, in the United Kingdom. Language use is at the heart of this issue, yet it is generally overlooked as an essential tool that links assessment, feedback and action planning for international students. The paper reveals existing and new data that builds on research since 2009, aimed at improving students’ assessment literacy. Recommendations are offered to stimulate local and global discussion about keyword use for defining undergraduate assessment standards in art and design.

    Solar water heating systems are evaluated. Models were developed to estimate the percentage of energy supplied from the Sun to a household. Since solar water heating systems have random input and output queueing theory, birth and death processes were the major tools in developing the models of evaluation. Microeconomics methods help in determining the optimum size of the solar water heating system design parameters, i.e., the water tank volume and the collector area.

  1. Full factorial design applied to intercalation of amines in lamellar titanium phenylphosphonate and titanium phenylarsonate

    International Nuclear Information System (INIS)

    The intercalation of amines into titanium phenylphosphonate M(O3PC6H5)2 and titanium phenylarsonate M(O3AsC6H5)2 was investigated through batch and back-titration processes. Amine insertion in both layered lamellar inorganic matrices, measured by the number of moles of intercalated agent, was optimized using a complete factorial design based on two levels and four factors. The effects of solvent, ethanol and acetonitrile, neutral organic base, ethyl and propylamines, H3C(CH2)nNH2 (n=1, 2), and material mass, 30 and 40 mg, on amine insertion in both lamellar inorganic matrices was optimized using a full factorial design. Important positive effect values, 0.40x10-3 and 0.69x10-3 mol g-1 were observed for inorganic material and solvent whereas a negative effect, -0.33x10-3 mol g-1 was observed for material mass. Two significant but less important binary interactions were also observed. The use of either ethyl or propylamine does not appear to affect the quantity of amine insertion. Recommended experimental conditions for maximum amine insertion obtained from this factorial design are 30 mg of titanium phenylarsonate in acetonitrile solvent using either of the studied amines

    Full Text Available The objective of this study is to introduce a simple experimental apparatus based on the applied forces for quantitative assessment on hot tearing behavior in aluminum alloys. According to the experimental procedure, molten metal is cast in the rod-shaped mold cavity. One side of the casting specimen is hooked by a steel bolt which restrains its free contraction and transfers the tensile forces during solidification. A steel threaded rod connected to a load cell which records the real-time measurement of the tensile forces during every experiment. Thermal history is monitored by K-type thermocouple. The data of the temperature and tensile forces are acquired by a data acquisition system. Test of the experimental apparatus is conducted with A356 and Al-5 wt% Cu alloy to investigate the accuracy of the experimental apparatus and modify its operating parameter. The tensile forces curves and the temperature curves of the specimens are obtained by experiment. This data provide useful information about hot tearing formation and solidification characteristics, from which their quantitative relations are derived. In this manner, the hot tearing behavior in aluminum alloys can be studied by this experimental apparatus based on the applied forces.

    A decomposition methodology based on the concept of 'thermoeconomic isolation' and applied to the synthesis/design and operational optimization of an advanced tactical fighter aircraft is the focus of this paper. The total system is composed of six sub-systems of which five participate with degrees of freedom (493) in the optimization. They are the propulsion sub-system (PS), the environmental control sub-system (ECS), the fuel loop subsystem (FLS), the vapor compression and Polyalphaolefin (PAO) loops sub-system (VC/PAOS), and the airframe sub-system (AFS). The sixth subsystem comprises the expendable and permanent payloads as well as the equipment group. For each of the first five, detailed thermodynamic, geometric, physical, and aerodynamic models at both design and off-design were formulated and implemented. The most promising set of aircraft sub-system and system configurations were then determined based on both an energy integration and aerodynamic performance analysis at each stage of the mission (including the transient ones). Conceptual, time, and physical decomposition were subsequently applied to the synthesis/design and operational optimization of these aircraft configurations as well as to the highly dynamic process of heat generation and dissipation internal to the subsystems. The physical decomposition strategy used (i.e. Iterative Local-Global Optimization-ILGO) is the first to successfully closely approach the theoretical condition of 'thermoeconomic isolation' when applied to highly complex, highly dynamic non-linear systems. Developed at our Center for Energy Systems research, it has been effectively applied to a number of complex stationary and transportation applications.

  18. Design of phantoms and software for automatic image analysis applied to digital radiographic equipments

    International Nuclear Information System (INIS)

    In a quality control of the radiographic equipment, the quality of the obtained image is very useful to characterize the physical properties of the image radiographic chain. In the radiographic technique it is necessary that the evaluation of the image can guarantee the constancy of its quality to carry out a suitable diagnosis. The use of digital systems allows the automatic analysis of the obtained radiographic images, increasing the objectivity in the evaluation of the image. In this work we have designed some radiographic phantoms for different radiographic digital devices, as dental, conventional, equipments with computed radiography (phosphor plate) and direct radiography (sensor) technology. Additionally, we have developed a software to analyse the image obtained by the radiographic equipment with digital processing techniques as edge detector, morphological operators, statistical test for the detected combinations.. The images have been acquired in DICOM, tiff.. format and they can be analysed with objective parameters as an image quality index and the contrast detail curve. The design of these phantoms let the evaluation of a wide range of operating conditions of voltage, current and time of the digital equipments. Moreover, the image quality analysis by the automatic software let study it with objective parameters and the functioning of the image chain of the digital system. (author)

  19. PID Controllers Design Applied to Positioning of Ball on the Stewart Platform

    Directory of Open Access Journals (Sweden)

    Koszewnik Andrzej

    2014-12-01

    Full Text Available The paper presents the design and practical implementation of PID controllers for a Stewart platform. The platform uses a resistance touch panel as a sensor and servo motors as actuators. The complete control system stabilizing the ball on the platform is realized with the Arduino microcontroller and the Matlab/Simulink software. Two processes required to acquire measurement signals from the touch panel in two perpendicular directions X and Y, are discussed. The first process includes the calibration of the touch panel, and the second process - the filtering of measurement signals with the low pass Butterworth filter. The obtained signals are used to design the algorithm of the ball stabilization by decoupling the global system into two local subsystems. The algorithm is implemented in a soft real time system. The parameters of both PID controllers (PIDx and PIDy are tuned by the trial-error method and implemented in the microcontroller. Finally, the complete control system is tested at the laboratory stand.

  20. Applying human factors to the design of control centre and workstation of a nuclear reactor

    International Nuclear Information System (INIS)

    Human factors is a body of scientific factors about human characteristics, covering biomedical, psychological and psychosocial considerations, including principles and applications in the personnel selection areas, training, job performance aid tools and human performance evaluation. Control Centre is a combination of control rooms, control suites and local control stations which are functionally related and all on the same site. Digital control room includes an arrangement of systems, equipment such as computers and communication terminals and workstations at which control and monitoring functions are conducted by operators. Inadequate integration between control room and operators reduces safety, increases the operation complexity, complicates operator training and increases the likelihood of human errors occurrence. The objective of this paper is to present a specific approach for the conceptual and basic design of the control centre and workstation of a nuclear reactor used to produce radioisotope. The approach is based on human factors standards, guidelines and the participation of a multidisciplinary team in the conceptual and basic phases of the design. Using the information gathered from standards and from the multidisciplinary team, an initial sketch 3D of the control centre and workstation are being developed. (author)
