    Full Text Available The main objective of this study is to evaluate the basis of an assessment in the architectural design studio and try to provide a new assessment method that is more precise and objective. Determining the criteria-based assessment methods and grading is very important in architectural design. This aims to avoid a holistic assessment, subjective, introverted and less explicit. The criteria-based assessment and grading refers to the process of forming a decision about the quality and level of student achievement or performance in a transparent, truthful and fair. So it will not cause disputes and dissatisfaction that have an impact on the mental and spirit of the students themselves. Students deserve to know which of their works and under what kind of criteria will be assessed. Coupled with the views and assessment of a work of a judge with other judges would have a different perception, so as to avoid subjective judgments, it is necessary to create a standard model that regulates how the appropriate assessment criteria and helps the creativity of the students in the architecture studio. With the criterion-based grading in architecture and design, students will know what the criteria will be assessed and trying to reach assessment targets that must be fulfilled. Then the jurors will also be easier to determine the appropriate value based on the assessment criteria that have been previously defined.

  2. “Multi-Criteria Analysis of the Design Decisions In Architectural Design Process during the Pre-Design Stage”

    Directory of Open Access Journals (Sweden)

    2014-05-01

    Full Text Available Design studio in architectural education is a traditional process, based on the methodology related to the aims and objectives of those respective studio curriculum, and the experience and expectation of the faculty members as what they wants the students to learn, and expected to synthesis their knowledge gained from other sources and previous studio experiences. One of the weaknesses of the traditional studio practice is that the design exercises were given so much attention to the compositional aspects of design rather than attempting to study complex and multi-criteria approach for those decisions. To understand the importance of rational decision method over the intuitive decisions, an architectural studio project was explored with the design brief as to develop a morphological variation to create the alternatives as design solutions. All those design alternatives have been evaluated by different stakeholders namely the fellow students, faculty members, and post graduate students who are mainly the architects. The objective of the evaluation is to develop an empirical analysis and evaluation of framework for assessing the Architectural Design to check is there a correlation between the different value judgment for intuitive method of decision making and rational method of decision making, of the pre design alternatives.

  3. Architectural design criteria for f-block metal sequestering agents. 1997 annual progress report

    International Nuclear Information System (INIS)

    'The objective of this project is to provide the means to optimize ligand architecture for f-block metal recognition. The authors strategy builds on an innovative and successful molecular modeling approach in developing polyether ligand design criteria for the alkali and alkaline earth cations. The hypothesis underlying this proposal is that differences in metal ion binding with multidentate ligands bearing the same number and type of donor groups are primarily attributable to intramolecular steric factors. The authors propose quantifying these steric factors through the application of molecular mechanics models. The proposed research involves close integration of theoretical and experimental chemistry. The experimental work entails synthesizing novel ligands and experimentally determining structures and binding constants for metal ion complexation by series of ligands in which architecture is systematically varied. The theoretical work entails using electronic structure calculations to parameterize a molecular mechanics force field for a range of metal ions and ligand types. The resulting molecular mechanics force field will be used to predict low-energy structures for unidentate, bidentate, and multidentate ligands and their metal complexes through conformational searches. Results will be analyzed to assess the relative importance of several steric factors including optimal M-L length, optimal geometry at the metal center, optimal geometry at the donor atoms (complementarity), and conformation prior to binding (preorganization). An accurate set of criteria for the design of ligand architecture will be obtained from these results. These criteria will enable researchers to target ligand structures for synthesis and thereby dramatically reduce the time and cost associated with metal-specific ligand development.'

  4. Design theory versus architectural design

    OpenAIRE

    W R Spillers

    1986-01-01

    This paper is an attempt to track the path of architectural design both on design-theoretical and on practical (computer-aided design) planes. It begins with the practical problems of design which can be couched in terms of mathematical programming problems. The potential for applications of artificial intelligence and knowledge-based systems in architectural design is then considered. Last the place of architectural design within design theory is discussed.

  5. Human Systems Design Criteria

    DEFF Research Database (Denmark)

    Rasmussen, Jens

    1982-01-01

    This paper deals with the problem of designing more humanised computer systems. This problem can be formally described as the need for defining human design criteria, which — if used in the design process - will secure that the systems designed get the relevant qualities. That is not only the...... necessary functional qualities but also the needed human qualities. The author's main argument is, that the design process should be a dialectical synthesis of the two points of view: Man as a System Component, and System as Man's Environment. Based on a man's presentation of the state of the art a set of...

  6. Software Architecture Design Reasoning

    Science.gov (United States)

    Tang, Antony; van Vliet, Hans

    Despite recent advancements in software architecture knowledge management and design rationale modeling, industrial practice is behind in adopting these methods. The lack of empirical proofs and the lack of a practical process that can be easily incorporated by practitioners are some of the hindrance for adoptions. In particular, the process to support systematic design reasoning is not available. To rectify this issue, we propose a design reasoning process to help architects cope with an architectural design environment where design concerns are cross-cutting and diversified.We use an industrial case study to validate that the design reasoning process can help improve the quality of software architecture design. The results have indicated that associating design concerns and identifying design options are important steps in design reasoning.

    Marković, Dejan

    2012-01-01

    In DSP Architecture Design Essentials, authors Dejan Marković and Robert W. Brodersen cover a key subject for the successful realization of DSP algorithms for communications, multimedia, and healthcare applications. The book addresses the need for DSP architecture design that maps advanced DSP algorithms to hardware in the most power- and area-efficient way. The key feature of this text is a design methodology based on a high-level design model that leads to hardware implementation with minimum power and area. The methodology includes algorithm-level considerations such as automated word-length reduction and intrinsic data properties that can be leveraged to reduce hardware complexity. From a high-level data-flow graph model, an architecture exploration methodology based on linear programming is used to create an array of architectural solutions tailored to the underlying hardware technology. The book is supplemented with online material: bibliography, design examples, CAD tutorials and custom software.

  12. A Survey of Enterprise Architecture Analysis Using Multi Criteria Decision Making Models (MCDM)

    Science.gov (United States)

    Zia, Mehmooda Jabeen; Azam, Farooque; Allauddin, Maria

    System design becomes really important for software production due to continuous increase in size and complexity of software systems. It is a complex design activity to build architecture for the systems like large enterprises. Thus it is a critical issue to select the correct architecture in software engineering domain. Moreover, in enterprise architecture selection different goals and objectives must be taken into consideration as it is a multi-criteria decision making problem. Generally this field of enterprise architecture analysis has progressed from the application of linear weighting, through integer programming and linear programming to multi-criteria decision making (MCDM) models. In this paper we survey two multi-criteria decision making models (AHP, ANP) to determine that to what extent they have been used in making powerful decisions in complex enterprise architecture analysis. We have found that by using ANP model, decision makers of an enterprise can make more precise and suitable decisions in selection of enterprise architecture styles.

  15. nuclear fuel design criteria

    International Nuclear Information System (INIS)

    Nuclear fuel design is strictly dependent on reactor type and experiences obtained from performance of nuclear fuels. The objectives of the design are reliability, and economy. Nuclear fuel design requires an interdisciplinary work which has to cover, at least nuclear design, thermalhydraulic design, mechanical design, and material properties.The procedure of design, as describe in the quality assurance, consist of a number of steps. The most important parts are: Design description or inputs, preliminary design, detailed design and design output, and design verification. The first step covers objectives and requirements, as defined by the customer and by the regulatory authority for product performance,environmental factors, safety, etc. The second describes assumptions and alternatives, safety, economy and engineering analyses. The third covers technical specifications, design drawings, selection of QA program category, etc. The most important form of design verification is design review by qualified independent internal or external reviewers. The scope of the review depends on the specific character of the design work. Personnel involved in verification and review do not assume prime responsibility for detecting errors. Responsibility for the design remains with the personnel involved in the design work

  1. New facility shield design criteria

    International Nuclear Information System (INIS)

    The purpose of the criteria presented here is to provide standard guidance for the design of nuclear radiation shields thoughout new facilities. These criteria are required to assure a consistent and integrated design that can be operated safely and economically within the DOE standards. The scope of this report is confined to the consideration of radiation shielding for contained sources. The whole body dose limit established by the DOE applies to all doses which are generally distributed throughout the trunk of the body. Therefore, where the whole body is the critical organ for an internally deposited radionuclide, the whole body dose limit applies to the sum of doses received must assure control of the concentration of radionuclides in the building atmosphere and thereby limit the dose from internal sources

    Bhansali, Sanjay; Nii, H. Penny

    1992-01-01

    Abstraction fosters reuse by providing a class of artifacts that can be instantiated or customized to produce a set of artifacts meeting different specific requirements. It is proposed that significant leverage can be obtained by abstracting software system designs and the design process. The result of such an abstraction is a generic architecture and a set of knowledge-based, customization tools that can be used to instantiate the generic architecture. An approach for designing software systems based on the above idea are described. The approach is illustrated through an implemented example, and the advantages and limitations of the approach are discussed.

    2009-01-01

    The NASA Constellation Program is aiming to establish a long-term presence on the lunar surface. The Constellation elements (Orion, Altair, Earth Departure Stage, and Ares launch vehicles) will require a lunar navigation architecture for navigation state updates during lunar-class missions. Orion in particular has baselined earth-based ground direct tracking as the primary source for much of its absolute navigation needs. However, due to the uncertainty in the lunar navigation architecture, the Orion program has had to make certain assumptions on the capabilities of such architectures in order to adequately scale the vehicle design trade space. The following paper outlines lunar navigation requirements, the Orion program assumptions, and the impacts of these assumptions to the lunar navigation architecture design. The selection of potential sites was based upon geometric baselines, logistical feasibility, redundancy, and abort support capability. Simulated navigation covariances mapped to entry interface flightpath- angle uncertainties were used to evaluate knowledge errors. A minimum ground station architecture was identified consisting of Goldstone, Madrid, Canberra, Santiago, Hartebeeshoek, Dongora, Hawaii, Guam, and Ascension Island (or the geometric equivalent).

    Full Text Available In its parallel pursuit of an increased competitivity for design offices and more pleasurable and easier workflows for designers, artificial design intelligence is a technical, intellectual, and political challenge. While human-machine cooperation has become commonplace through Computer Aided Design (CAD tools, a more improved collaboration and better support appear possible only through an endeavor into a kind of artificial design intelligence, which is more sensitive to the human perception of affairs.Considered as part of the broader Computational Design studies, the research program of this quest can be called Artificial / Autonomous / Automated Design (AD. The current available level of Artificial Intelligence (AI for design is limited and a viable aim for current AD would be to develop design assistants that are capable of producing drafts for various design tasks. Thus, the overall aim of this thesis is the development of approaches, techniques, and tools towards artificial design assistants that offer a capability for generating drafts for sub-tasks within design processes. The main technology explored for this aim is Evolutionary Computation (EC, and the target design domain is architecture. The two connected research questions of the study concern, first, the investigation of the ways to develop an architectural design assistant, and secondly, the utilization of EC for the development of such assistants.While developing approaches, techniques, and computational tools for such an assistant, the study also carries out a broad theoretical investigation into the main problems, challenges, and requirements towards such assistants on a rather overall level. Therefore, the research is shaped as a parallel investigation of three main threads interwoven along several levels, moving from a more general level to specific applications. The three research threads comprise, first, theoretical discussions and speculations with regard to both existing

    2009-01-01

    Most existing system-on-chip (SoC) architectures are for microprocessor-centric designs. They are not suitable for computing intensive SoCs, which have their own configurability, extendibility, perform-ance, and data exchange characteristics. This paper analyzes these characteristics and gives design princi-ples for computing intensive SoCs. Three architectures suitable for different situations are compared with selection criteria given. The architectural design of a high performance network security accelerator (HPNSA) is used to elaborate on the design techniques to fully exploit the performance potential of the ar-chitectures. A behavior-level simulation system is implemented with the C++ programming language to evaluate the HPNSA performance and to obtain the optimum system design parameters. Simulations show that this architecture provides high performance data transfer.

  1. Redefining design criteria for Pu-238 gloveboxes

    Energy Technology Data Exchange (ETDEWEB)

    Acosta, S.V.

    1998-12-31

    Enclosures for confinement of special nuclear materials (SNM) have evolved into the design of gloveboxes. During the early stages of glovebox technology, established practices and process operation requirements defined design criteria. Proven boxes that performed and met or exceeded process requirements in one group or area, often could not be duplicated in other areas or processes, and till achieve the same success. Changes in materials, fabrication and installation methods often only met immediate design criteria. Standardization of design criteria took a big step during creation of ``Special-Nuclear Materials R and D Laboratory Project, Glovebox standards``. The standards defined design criteria for every type of process equipment in its most general form. Los Alamos National Laboratory (LANL) then and now has had great success with Pu-238 processing. However with ever changing Environment Safety and Health (ES and H) requirements and Ta-55 Facility Configuration Management, current design criteria are forced to explore alternative methods of glovebox design fabrication and installation. Pu-238 fuel processing operations in the Power Source Technologies Group have pushed the limitations of current design criteria.

    Full Text Available This article deals with the problem of criteria optimization in order to objectively evaluate the experience of an applicant (a project organization and the quality of a design product (project documentation. The methodology to be developed is based on introduction of new evaluation criteria (sub-criteria that in conjunction with the applicable criteria specified by the Law on the Contract System will allow developing the optimal procedure to evaluate competitive bids of the participants in tenders and determining the most appropriate candidate, with whom the contract will be further concluded. The article analyzes the existing criteria and their interaction with each other and describes the specifics of tenders for design in the form of open competition. The list decreases to three criteria, such as "contract price", "quality, functional and environmental characteristics of a procurement facility", "qualification of procurement participants, including availability of financial resources, equipment and other material resources necessary for the execution of the contract material resources, the presence of goodwill, professionals and other employees of a certain experience level". However, in order to upgrade the quality of assurance procedures for the design works to be performed, it was decided to apply new evaluation criteria (sub-criteria components, such as "availability of positive findings of the state out-of-departmental examination that are similar to the subject of competition, on a participant in placement of order", "availability of the certificate on approval of architectural and urban planning decisions that are similar to the subject of competition, on a participant in placement of order", "availability of the permit for the commissioning of facilities that are similar to the subject of competition, on a participant in placement of order", "availability of the contract for designer's supervision with a participant in placement of

    1999-07-01

    The development of this Standard reflects the fact that national consensus standards and other design criteria do not comprehensively or, in some cases, adequately address fire protection issues at DOE facilities. This Standard provides supplemental fire protection guidance applicable to the design and construction of DOE facilities and site features (such as water distribution systems) that are also provided for fire protection. It is intended to be used in conjunction with the applicable building code, National Fire Protection Association (NFPA) Codes and Standards, and any other applicable DOE construction criteria. This Standard replaces certain mandatory fire protection requirements that were formerly in DOE 5480.7A, ``Fire Protection``, and DOE 6430.1A, ``General Design Criteria``. It also contains the fire protection guidelines from two (now canceled) draft standards: ``Glove Box Fire Protection`` and ``Filter Plenum Fire Protection``. (Note: This Standard does not supersede the requirements of DOE 5480.7A and DOE 6430.1A where these DOE Orders are currently applicable under existing contracts.) This Standard, along with the criteria delineated in Section 3, constitutes the basic criteria for satisfying DOE fire and life safety objectives for the design and construction or renovation of DOE facilities.

    This chapter introduces a component design of application logic in special type of information system architecture called Open Design Architecture for Round Trip Engineering (ODARTE). This architecture supports model-driven development and integrates information system design with its executable form. It is possible to extract design anytime, modify it, and load back to change the activity and behavior of information system. In this approach, the application logic represents solely functionality and can be described either by sequential model of Windows Workflow Foundation or by UML activity or interaction diagrams. This approach allows creation of flexible and modifiable meta-design of application logic. Finally, an experimental simulation is shown demonstrating the effect of proposal which relates to pilot version of runtime environment for ODARTE support.

    This book provides the readers with a timely guide to the application of biomimetic principles in architecture and engineering design. As a result of a combined effort by two internationally recognized authorities, the biologist Werner Nachtigall and the architect Göran Pohl, the book describes the principles which can be used to compare nature and technology, and at the same time it presents detailed explanations and examples showing how biology can be used as a source of inspiration and “translated” in building and architectural solutions (biomimicry). Even though nature cannot be directly copied, the living world can provide architects and engineers with a wealth of analogues and inspirations for their own creative designs. But how can analysis of natural entities give rise to advanced and sustainable design?

  19. Architecture design of a virtualized embedded system

    Directory of Open Access Journals (Sweden)

    A.Sbaa

    2013-01-01

    Full Text Available Nowadays, embedded systems have become a major driver of technological developments particularly in the industrial sector. In an embedded system, the hardware and software components are so intertwined that evolution is often a big issue. Thanks to the contributions of virtualization it is possible to design more flexible and scalable embedded systems. In fact, virtualization adds an abstraction layer between the hardware and the software to make it less intimately dependent. In this paper we propose system architecture based on embedded virtualization that will be modeled by the multi-agent systems. In the first part, we will discuss the state of the art with respect to embedded systems, multi-agent systems and the concept of virtualization. In the second part, we explain theissues related to traditional embedded systems and the constraints associated with their architecture. Subsequently, we propose a virtualization based architecture for embedded systems. In the last part we will showcase this architecture through a prototype.

  20. Evaluation criteria for spectral design of camouflage

    Science.gov (United States)

    Škerlind, Christina; Fagerström, Jan; Hallberg, Tomas; Kariis, Hans

    2015-10-01

    In development of visual (VIS) and infrared (IR) camouflage for signature management, the aim is the design of surface properties of an object to spectrally match or adapt to a background and thereby minimizing the contrast perceived by a threatening sensor. The so called 'ladder model" relates the requirements for task measure of effectiveness with surface structure properties through the steps signature effectiveness and object signature. It is intended to link materials properties via platform signature to military utility and vice versa. Spectral design of a surface intends to give it a desired wavelength dependent optical response to fit a specific application of interest. Six evaluation criteria were stated, with the aim to aid the process to put requirement on camouflage and for evaluation. The six criteria correspond to properties such as reflectance, gloss, emissivity, and degree of polarization as well as dynamic properties, and broadband or multispectral properties. These criteria have previously been exemplified on different kinds of materials and investigated separately. Anderson and Åkerlind further point out that the six criteria rarely were considered or described all together in one and same publication previously. The specific level of requirement of the different properties must be specified individually for each specific situation and environment to minimize the contrast between target and a background. The criteria or properties are not totally independent of one another. How they are correlated is part of the theme of this paper. However, prioritization has been made due to the limit of space. Therefore all of the interconnections between the six criteria will not be considered in the work of this report. The ladder step previous to digging into the different material composition possibilities and choice of suitable materials and structures (not covered here), includes the object signature and decision of what the spectral response should be

  1. Studies in Criticality Control: Design Criteria

    International Nuclear Information System (INIS)

    Criteria are developed to assist plant designers, operating personnel, and safeguards review groups in eliminating criticality hazards normally associated with operating nuclear reactors and chemical plants processing fissionable material. The criteria are conservative both from the nature of the analytical treatment and from the choice of nuclear parameters used in the analysis. They are not, however, so conservative as to be unduly restrictive. Large homogeneous systems are made critically safe either by the use of a homogeneously distributed poison or by the superposition of a lattice opaque to thermal neutrons. Individual units of any array are isolated from each other by poison-moderator shells surrounding each unit. The treatment supplements the more conventional presentations which rely almost entirely on mass, density, and volume limitations for units and on geometric specifications for arrays of units. Problems of interaction are eliminated because one has either isolated units or infinitely large, critically safe units. Wherever the results of these studies have been compared with critical experiments, the conservative, but realistic, nature of the treatment has been confirmed. The criteria show unambiguously what situations are safe and what situations require more elaborate analysis before they can be classified as safe or hazardous. The criteria are displayed as families of curves which attempt to cover the entire range of interesting values of a system's parameters. The general systems are easily related to specific problems.

  2. LPI Optimization Framework for Target Tracking in Radar Network Architectures Using Information-Theoretic Criteria

    Directory of Open Access Journals (Sweden)

    2014-01-01

    Full Text Available Widely distributed radar network architectures can provide significant performance improvement for target detection and localization. For a fixed radar network, the achievable target detection performance may go beyond a predetermined threshold with full transmitted power allocation, which is extremely vulnerable in modern electronic warfare. In this paper, we study the problem of low probability of intercept (LPI design for radar network and propose two novel LPI optimization schemes based on information-theoretic criteria. For a predefined threshold of target detection, Schleher intercept factor is minimized by optimizing transmission power allocation among netted radars in the network. Due to the lack of analytical closed-form expression for receiver operation characteristics (ROC, we employ two information-theoretic criteria, namely, Bhattacharyya distance and J-divergence as the metrics for target detection performance. The resulting nonconvex and nonlinear LPI optimization problems associated with different information-theoretic criteria are cast under a unified framework, and the nonlinear programming based genetic algorithm (NPGA is used to tackle the optimization problems in the framework. Numerical simulations demonstrate that our proposed LPI strategies are effective in enhancing the LPI performance for radar network.

This paper tries to highlight the functional and architectural integration with ecstatic elements in the form of decorative and ornamental outlay as well as incorporating the building structure such as wall, domes and gates. This paper further focuses the mathematical aspects of the architectural designs such as polar equations and the golden ratio. These designs are modelled into mathematical equations of various forms, while the golden ratio in mosque is verified using two techniques namely, the geometric construction and the numerical method. The exemplary designs are taken from theSabah Bandaraya Mosque in Likas, Kota Kinabalu and the Sarawak State Mosque in Kuching,while the Universiti Malaysia Sabah Mosque is used for the Golden Ratio. Results show thatIslamic architectural buildings and designs have long had mathematical concepts and techniques underlying its foundation, hence, a modelling approach is needed to rejuvenate these Islamic designs.

  5. Design criteria for FBR core components

    International Nuclear Information System (INIS)

    This paper outlines the general approach adopted in France to take into account the specific behavior of irradiated steel for functional and structural verification of fast breeder reactor core components. Functional verification deals with the distortions which appear in structures as a result of void swelling and irradiation creep. Specific criteria must be defined to limit these distortions to acceptable values: these criteria are highly dependent on the subassembly and core design. Structural verification deals with modifications of the mechanical properties of steel submitted to FBR flux. Conventional standards and rules are not applicable, and a new methodology must be defined to take into account the new characteristics of irradiated steel. The general R and D program set up to investigate these areas is presented here as it is implemented in France but with emphasis on integration in a joint European program

    2010-01-01

    Selecting a communications and network architecture for future manned space flight requires an evaluation of the varying goals and objectives of the program, development of communications and network architecture evaluation criteria, and assessment of critical architecture trades. This paper uses Cx Program proposed exploration activities as a guideline; lunar sortie, outpost, Mars, and flexible path options are described. A set of proposed communications network architecture criteria are proposed and described. They include: interoperability, security, reliability, and ease of automating topology changes. Finally a key set of architecture options are traded including (1) multiplexing data at a common network layer vs. at the data link layer, (2) implementing multiple network layers vs. a single network layer, and (3) the use of a particular network layer protocol, primarily IPv6 vs. Delay Tolerant Networking (DTN). In summary, the protocol options are evaluated against the proposed exploration activities and their relative performance with respect to the criteria are assessed. An architectural approach which includes (a) the capability of multiplexing at both the network layer and the data link layer and (b) a single network layer for operations at each program phase, as these solutions are best suited to respond to the widest array of program needs and meet each of the evaluation criteria.

    This report describes the architectural design for a high fidelity simulation of a refinery and refinery burner, including demonstrations of impacts to the refinery if errors occur during the refinery process. The refinery burner model and simulation are a part of the capabilities within the Sandia National Laboratories Virtual Control System Environment (VCSE). Three components comprise the simulation: HMIs developed with commercial SCADA software, a PLC controller, and visualization software. All of these components run on different machines. This design, documented after the simulation development, incorporates aspects not traditionally seen in an architectural design, but that were utilized in this particular demonstration development. Key to the success of this model development and presented in this report are the concepts of the multiple aspects of model design and development that must be considered to capture the necessary model representation fidelity of the physical systems.

    We developed a new tool, Healthy Eating Design Guidelines for School Architecture, to provide practitioners in architecture and public health with a practical set of spatially organized and theory-based strategies for making school environments more conducive to learning about and practicing healthy eating by optimizing physical resources and learning spaces. The design guidelines, developed through multidisciplinary collaboration, cover 10 domains of the school food environment (eg, cafeteria, kitchen, garden) and 5 core healthy eating design principles. A school redesign project in Dillwyn, Virginia, used the tool to improve the schools’ ability to adopt a healthy nutrition curriculum and promote healthy eating. The new tool, now in a pilot version, is expected to evolve as its components are tested and evaluated through public health and design research. PMID:23449281

  1. Design Criteria For Networked Image Analysis System

    Science.gov (United States)

    Reader, Cliff; Nitteberg, Alan

    1982-01-01

    Image systems design is currently undergoing a metamorphosis from the conventional computing systems of the past into a new generation of special purpose designs. This change is motivated by several factors, notably among which is the increased opportunity for high performance with low cost offered by advances in semiconductor technology. Another key issue is a maturing in understanding of problems and the applicability of digital processing techniques. These factors allow the design of cost-effective systems that are functionally dedicated to specific applications and used in a utilitarian fashion. Following an overview of the above stated issues, the paper presents a top-down approach to the design of networked image analysis systems. The requirements for such a system are presented, with orientation toward the hospital environment. The three main areas are image data base management, viewing of image data and image data processing. This is followed by a survey of the current state of the art, covering image display systems, data base techniques, communications networks and software systems control. The paper concludes with a description of the functional subystems and architectural framework for networked image analysis in a production environment.

  6. Advanced Neutron Source radiological design criteria

    International Nuclear Information System (INIS)

    The operation of the proposed Advanced Neutron Source (ANS) facility will present a variety of radiological protection problems. Because it is desired to design and operate the ANS according to the applicable licensing standards of the Nuclear Regulatory Commission (NRC), it must be demonstrated that the ANS radiological design basis is consistent not only with state and Department of Energy (DOE) and other usual federal regulations, but also, so far as is practicable, with NRC regulations and with recommendations of such organizations as the Institute of Nuclear Power Operations (INPO) and the Electric Power Research Institute (EPRI). Also, the ANS radiological design basis is in general to be consistent with the recommendations of authoritative professional and scientific organizations, specifically the National Council on Radiation Protection and Measurements (NCRP) and the International Commission on Radiological Protection (ICRP). As regards radiological protection, the principal goals of DOE regulations and guidance are to keep occupational doses ALARA [as low as (is) reasonably achievable], given the current state of technology, costs, and operations requirements; to control and monitor contained and released radioactivity during normal operation to keep public doses and releases to the environment ALARA; and to limit doses to workers and the public during accident conditions. Meeting these general design objectives requires that principles of dose reduction and of radioactivity control by employed in the design, operation, modification, and decommissioning of the ANS. The purpose of this document is to provide basic radiological criteria for incorporating these principles into the design of the ANS. Operations, modification, and decommissioning will be covered only as they are affected by design

    Full Text Available This paper primarily reflects on the need to create graphical codes for producing images intended to communicate architecture. Each step of the drawing needs to be a deliberate process in which the proposed code highlights the relationship between architectural theory and graphic action. Our aim is not to draw the result of the architectural process but the design structure of the actual process; to draw as we design; to draw as we build. This analysis of the work of the Late Gothic architect Hernan Ruiz the Elder, from Cordoba, addresses two aspects: the historical and architectural investigation, and the graphical project for communication purposes.

  13. Monitoring programmes for internal exposure: designing criteria

    International Nuclear Information System (INIS)

    The purpose of this document is to offer guidance for the decision whether a monitoring programme is required and how it should be designed. It can be also used as a tool for making the standing programmes consistent with the most recent publications on internal dosimetry, such as ISO 20553 'Monitoring of workers occupationally exposed to a risk of internal contamination with radioactive material', specific publications of the IAEA and ICRP, and including the conclusions of the OMINEX Project ('Optimisation of Monitoring for Internal Exposures') and IDEAS Project. It is established that the general purpose of the monitoring is verify that each worker is protected adequately against risks from radionuclide intakes and document that the protection complies with legal requirements. The criteria for a particular monitoring programme designing is based on the magnitude of the probable intake and the possibility of detecting a significant event when it occurs. So, the risk assessment for each work process must be evaluated and each worker is classified accordingly. This classification implies the acceptance of reference effective dose values (1 y 6 mSv/y ). (author)

    2015-05-01

    Integrated Sensor Architecture (ISA) is designed in response to stovepiped integration approaches. The design, based on the principles of Service Oriented Architectures (SOA) and Open Architectures, addresses the problem of integration, and is not designed for specific sensors or systems. The use of SOA and Open Architecture approaches has led to a flexible, extensible architecture. Using these approaches, and supported with common data formats, open protocol specifications, and Department of Defense Architecture Framework (DoDAF) system architecture documents, an integration-focused architecture has been developed. ISA can help move the Department of Defense (DoD) from costly stovepipe solutions to a more cost-effective plug-and-play design to support interoperability.

  18. Metaphor, Architectural Design, and Environmental Response

    Directory of Open Access Journals (Sweden)

    2012-11-01

    Full Text Available Value-laden articulations of the task of the architect guide manners of working - the concerns, inspirations and procedures given priority. Architectural practices in turn determine the nature of the physical constructs that result. If architects are contributing to environmental degradation by designing buildings that are inefficient and unhealthy, and a pressing need exists to advance more life enhancing, sustaining practices, then perhaps environmentally concerned architects ought not only work towards the creation of better performing, more resourceful building assemblies, but also to engage in basic reflection as to how design problems are expressed and the environmental receptivity such expressions reveal. By tracing the lineage binding utterance to practice to making, we might come to recognize that even subtle shifts in articulation can alter outcomes dramatically. Through such newfound awareness, we are open and encouraged to reexamine the architect’s role, to new descriptions of architecture, and to the possibility of deeper attunement and constructive engagement with our world. In their recent edited anthology on sustainable architectures, Simon Guy and Steven Moore suggest “while we might support and even encourage critical engagement with abstract theory about environmentalism, we are not interested in simply playing language games.” Although word play should not be the sole focus of our efforts, in a profession so reliant on effective communication, we should not underestimate the facility of language as constitutive of meaning. This paper explores metaphors as one potentially transformative means by which designers come to understand and describe the works they undertake. It examines the role of metaphors as agents of innovation, capable of heightening awareness of attributes often overlooked or undervalued, yet perhaps of critical significance given the particularities of a design problem seeking explication.

The first two criteria can prevent radon from infiltrating...... from the ground, and the third criteria can dilute the indoor air. By combining these three criteria, the indoor radon concentration can be lowered achieving an acceptable level. In addition, a cheap and reliable method for measuring the radon concentration in the indoor air is described. The provision...

  2. Physical Activity Design Guidelines for School Architecture.

    Directory of Open Access Journals (Sweden)

    Jeri Brittin

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

    Architects, artists, and designers have been fascinated by robots for many decades, from Villemard’s utopian vision of an architect building a house with robotic labor in 1910, to the design of buildings that are robots themselves, such as Archigram’s Walking City. Today, they are again approaching the topic of robotic fabrication but this time employing a different strategy: instead of utopian proposals like Archigram’s or the highly specialized robots that were used by Japan’s construction industry in the 1990s, the current focus of architectural robotics is on industrial robots. These robotic arms have six degrees of freedom and are widely used in industry, especially for automotive production lines. What makes robotic arms so interesting for the creative industry is their multi-functionality: instead of having to develop specialized machines, a multifunctional robot arm can be equipped with a wide range of end-effectors, similar to a human hand using various tools. Therefore, architectural researc...

    2015-08-01

    Full Text Available “Cloud” computing a comparatively term, stands on decades of research & analysis in virtualization, analytical distributed computing, utility computing, and more recently computer networking, web technology and software services. Cloud computing represents a shift away from computing as a product that is purchased, to computing as a service that is delivered to consumers over the internet from large-scale data centers – or “clouds”. Whilst cloud computing is obtaining growing popularity in the IT industry, academic appeared to be lagging behind the developments in this field. It also implies a service oriented designed architecture, reduced information technology overhead for the end-user, good flexibility, reduced total cost of private ownership, on-demand services and many other things. This paper discusses the concept of “cloud” computing, some of the issues it tries to address, related research topics, and a “cloud” implementation available today

  14. An energy efficiency evaluation of architectural and construction solutions of an initial design stage in Autodesk REVIT Architecture

    Directory of Open Access Journals (Sweden)

    S.A. Bolotin

    2013-12-01

    Full Text Available The aim of this study was to develop evaluation criteria for the various options of the project on the basis of information of the initial design phase. Objective of the study was to develop a methodology for assessing the architectural decisions on the basis of the building information model (BIM, formed by the program Autodesk Revit Architecture. The study suggested new compact solutions for evaluating insolation on vertical and horizontal surfaces and simplified algorithm for calculating the heat loss of the building, allowing the introduction of the relevant information in a program like Revit Architecture to simulate virtual water and energy balance at the early stages of design. Applying the final value tariffs for water and electricity supply of the area, you can get a virtual operating cash flow. For correct economic comparison of conceptual design options you should take into account time differences in costs and revenues by discounting. For rapid assessment of design solutions a model that allows you to simulate the scheduling of the facility necessary for the formation of the investment cash flow was developed. The proposed method can significantly improve the ability of the variant design incorporated into the program such as Revit Architecture.

    2014-05-01

    Full Text Available Compared with high voltage direct current (HVDC, the primary and secondary systems of modular multilevel converter based HVDC (MMC-HVDC are complicated. And the characteristics of the control system determine the properties of the MMC-HVDC system to a certain extent. This paper investigates the design of control architecture. First, the structure and parameters of the 21-level MMC-HVDC are designed. Second, the framework of the control system is studied in details and a complete control system is established. The communication mode and content are built between each layer, and the control system program is developed and debugged. Then The steady state test platform of the sub-module and the relevant control system are designed. Finally, the steady-state tests and the system test of the physical MMC-HVDC simulation system are conducted, which prove that the SMC can control the sub-module (SM efficiently, and the control system could realize efficient start and stop of the physical system. Meanwhile, the capacitor voltage balance between the sub-modules and the basic fault protection and control of the DC voltage and power are verified to be effective.

    Ganesan, Dharmalingam; Lindvall, Mikael; Ackermann, Chris; McComas, David; Bartholomew, Maureen

    2009-01-01

    This paper presents experiences of verifying architectural design rules of the NASA Core Flight Software (CFS) product line implementation. The goal of the verification is to check whether the implementation is consistent with the CFS architectural rules derived from the developer's guide. The results indicate that consistency checking helps a) identifying architecturally significant deviations that were eluded during code reviews, b) clarifying the design rules to the team, and c) assessing the overall implementation quality. Furthermore, it helps connecting business goals to architectural principles, and to the implementation. This paper is the first step in the definition of a method for analyzing and evaluating product line implementations from an architecture-centric perspective.

    Fifty years ago, John von Neumann compared the architecture of the brain with that of the computers he invented and which are still in use today. In those days, the organization of computers was based on concepts of brain organization. Here, we give an update on current results on the global organization of neural systems. For neural systems, we outline how the spatial and topological architecture of neuronal and cortical networks facilitates robustness against failures, fast processing and balanced network activation. Finally, we discuss mechanisms of self-organization for such architectures. After all, the organization of the brain might again inspire computer architecture. PMID:17855223

    Science.gov (United States)

    Smith, I. S., Jr.

    1993-01-01

    The NASA philosophy and criteria for the design and flight of scientific balloons are set forth and discussed. The thickness of balloon films is standardized at 20.3 microns to isolate potential film problems, and design equations are given for specific balloon parameters. Expressions are given for: flight-stress index, total required thickness, cap length, load-tape rating, and venting-duct area. The balloon design criteria were used in the design of scientific balloons under NASA auspices since 1986, and the resulting designs are shown to be 95 percent effective. These results represent a significant increase in the effectiveness of the balloons and therefore indicate that the design criteria are valuable. The criteria are applicable to four balloon volume classes in combination with seven payload ranges.

    The technologies of software architecture are introduced, and the software analysis-and-design process is divided into requirement analysis, software architecture design and system design. Using these technologies, a model of architecture-centric software analysis and design process(ACSADP) is proposed. Meanwhile, with regard to the completeness, consistency and correctness between the software requirements and design results, the theories of function and process control are applied to ACSADP. Finally, a model of integrated development environment (IDE) for ACSADP is proposed. It can be demonstrated by the practice that the model of ACSADP can aid developer to manage software process effectively and improve the quality of software analysis and design.

    Frida Rosenberg

    2014-08-01

    Full Text Available How did architectural research in Sweden become scientific in its approach rather than artistic, as architecture education in the post-war period was primarily influenced by the Bauhaus pedagogy?
Via the American Bauhaus pedagogical developments taking place at the IIT and the GSD, Swedish architecture education adopted the artistic ‘learning by doing’ approach.The most interesting structure signifying this was a permanent exhibition of building materials located in the foreground of the 1957 KTH architecture school. When the new KTH architecture school was completed its architecture illustrated another image: that of the new architecture curriculum, A68, put into practice the same year as the building was designed. 
A68 reorganized architecture education and put more focus on environmental studies and building function analysis.The new curriculum included the subjects Formlära, Design Principles, and Byggnadsfunktionslära, Building Function Analysis, which were technical in their approach of using empirical research. As a result, the 1969 KTH architecture building included a laboratory for testing technical problems in air-conditioned spaces as well as a laboratory for testing acoustics. The 1961 LTH architecture building included a full-scale-laboratory where studies were directed by Carin Boalt, the first female professor at a technical university.

    2014-01-01

    Optimization of architecture design has recently drawn research interest. System deployment optimization (SDO) refers to the process of optimizing systems that are being deployed to activi-ties. This paper first formulates a mathematical model to theorize and operationalize the SDO problem and then identifies optimal so-lutions to solve the SDO problem. In the solutions, the success rate of the combat task is maximized, whereas the execution time of the task and the cost of changes in the system structure are mini-mized. The presented optimized algorithm generates an optimal solution without the need to check the entire search space. A novel method is final y proposed based on the combination of heuristic method and genetic algorithm (HGA), as wel as the combination of heuristic method and particle swarm optimization (HPSO). Experi-ment results show that the HPSO method generates solutions faster than particle swarm optimization (PSO) and genetic algo-rithm (GA) in terms of execution time and performs more efficiently than the heuristic method in terms of determining the best solution.

    CERN Document Server

    Constantinou, Eleni; Stamelos, Ioannis

    2011-01-01

    Modern software development methodologies include reuse of open source code. Reuse can be facilitated by architectural knowledge of the software, not necessarily provided in the documentation of open source software. The effort required to comprehend the system's source code and discover its architecture can be considered a major drawback in reuse. In a recent study we examined the correlations between design metrics and classes' architecture layer. In this paper, we apply our methodology in more open source projects to verify the applicability of our method.

  17. Seismic design and evaluation criteria based on target performance goals

    International Nuclear Information System (INIS)

    Seismic design and evaluation criteria have been developed based on target probabilistic performance goals. These criteria include selection of design/evaluation seismic input from probabilistic seismic hazard curves combined with commonly practiced deterministic response evaluation methods and acceptance criteria with controlled levels of conservatism. Conservatism is intentionally introduced in specification of material strengths and capacities, in the allowance of limited inelastic behavior, and by a seismic scale factor. Criteria have been developed following a graded approach for several performance goals ranging from that appropriate for normal-use facilities to that appropriate for facilities involving hazardous or critical operations. Performance goals are comprised of qualitative expressions of acceptable behavior and of quantitative probabilities that acceptable limits of behavior are maintained. The criteria are simple procedures but with a sound, rigorous basis for the achievement of goals

  3. Probabilistic determination of seismic design criteria

    International Nuclear Information System (INIS)

    A probabilistic technique of forecasting bedrock iso-acceleration contours in terms of time, magnitude, and exceedance probability is presented along with examples from field applications. The relationships among recurrence intervals, return periods, mean rates of occurrence time, exceedance probabilities, and nominal design levels are discussed and illustrated. It is shown that nominal deterministic design levels can be readily related to probabilistic measures including the influence of the design life and importance of the facility. It is shown that a consistent risk level for a given class of structure located in different seismic zones can be maintained. Seismic zoning, based on the concept of acceptable risk for a given class and use of structure is developed. Illustrative examples from practice are included. (Auth.)

    1982-01-01

    Methods for pre-screening stress constraints into either primary or side-constraint categories are reviewed; a projection method, which is developed from prior cycle stress resultant history, is introduced as an additional screening parameter. Stress resultant projections are also employed to modify the traditional stress-ratio, side-constraint boundary. A special application of structural modification reanalysis is applied to the critical stress constraints to provide feasible designs that are preferable to those obtained by conventional scaling. Sample problem executions show relatively short run times and fewer design cycle iterations to achieve low structural weights; those attained are comparable to the minimum values developed elsewhere.

    2007-01-01

    Full Text Available Many academic works in computer engineering focus on reconfigurable architectures and associated tools. Fine-grain architectures, field programmable gate arrays (FPGAs, are the most well-known structures of reconfigurable hardware. Dedicated tools (generic or specific allow for the exploration of their design space to choose the best architecture characteristics and/or to explore the application characteristics. The aim is to increase the synergy between the application and the architecture in order to get the best performance. However, there is no generic tool to perform such an exploration for coarse-grain or heterogeneous-grain architectures, just a small number of very specific tools are able to explore a limited set of architectures. To address this major lack, in this paper we propose a new design space exploration approach adapted to fine- and coarse-grain granularities. Our approach combines algorithmic and architecture explorations. It relies on an automatic estimation tool which computes the communication hierarchical distribution and the architectural processing resources use rate for the architecture under exploration. Such an approach forwards the rapid definition of efficient reconfigurable architectures dedicated to one or several applications.

    Full Text Available Many academic works in computer engineering focus on reconfigurable architectures and associated tools. Fine-grain architectures, field programmable gate arrays (FPGAs, are the most well-known structures of reconfigurable hardware. Dedicated tools (generic or specific allow for the exploration of their design space to choose the best architecture characteristics and/or to explore the application characteristics. The aim is to increase the synergy between the application and the architecture in order to get the best performance. However, there is no generic tool to perform such an exploration for coarse-grain or heterogeneous-grain architectures, just a small number of very specific tools are able to explore a limited set of architectures. To address this major lack, in this paper we propose a new design space exploration approach adapted to fine- and coarse-grain granularities. Our approach combines algorithmic and architecture explorations. It relies on an automatic estimation tool which computes the communication hierarchical distribution and the architectural processing resources use rate for the architecture under exploration. Such an approach forwards the rapid definition of efficient reconfigurable architectures dedicated to one or several applications.

    Modern software development methodologies include reuse of open source code. Reuse can be facilitated by architectural knowledge of the software, not necessarily provided in the documentation of open source software. The effort required to comprehend the system's source code and discover its architecture can be considered a major drawback in reuse. In a recent study we examined the correlations between design metrics and classes' architecture layer. In this paper, we apply our methodology in ...

  11. DESIGN CRITERIA OF A PROTON FFAG ACCELERATOR.

    Energy Technology Data Exchange (ETDEWEB)

    RUGGIERO, A.G.

    2004-10-13

    There are two major issues that are to be confronted in the design of a Fixed-Field Alternating-Gradient (FFAG) accelerator, namely: (1) the stability of motion over the large momentum range needed for the beam acceleration, and (2) the compactness of the trajectories over the same momentum range to limit the dimensions of the magnets. There are a numbers of rules that need to be followed to resolve these issues. In particular, the magnet arrangement in the accelerator lattice and the distribution of the bending and focusing fields are to be set properly in accordance with these rules. In this report they describe four of these rules that ought to be applied for the optimum design of a FFAG accelerator, especially in the case of proton beams.

    Maintainability must be designed into long-duration spacecraft and equipment to provide the required high probability of mission success with the least cost and weight. The ability to perform repairs quickly and easily in a space environment can be achieved by imposing specific maintainability design criteria on spacecraft equipment design and installation. A study was funded to investigate and define design criteria for electronic equipment that would permit rapid removal and replacement in a space environment. The results of the study are discussed together with subsequent simulated zero-g demonstration tests of a mockup with new concepts for packaging.

    The French Alzheimer plan anticipates new specialized structures for cognitive rehabilitation and psycho-behavioural therapy of Alzheimer's patients: the cognitive-behavioural units as follow-care units, the units of reinforced hospitalization inside the long term care units and the adapted activities units. this plan indicates the need to make healing gardens integral parts of these units. The benefits of green space in urban environments has been demonstrated with regards to physical, psychological and sociological effects and similarly studies in hospitals have revealed objective and measurable improvements of patients well being. Although green spaces and gardens are available in many French care units, they are rarely specifically adapted to the needs of Alzheimer's patients. For the garden "art, memory and life" a specific concept guided by a neuropsychological approach was developed, complemented by an artistic vision based on cultural invariants. It is already used in the frame of non-pharmacological therapies to improve symptoms such as deambulation, sleep disorders, apathy and aggressive behaviors. Based on the literature, and our experience and research, recommendations for the design of such gardens dedicated to Alzheimer's patients can be proposed. Beyond taking into account obvious aspects relating to security, allowing for free access, a careful design of walk-ways and a conscious choice of plants is needed. A systematic analysis of the existing green spaces or garden must be conducted in order to pinpoint the weakness of the space and identify the potential for developing it into a real healing garden. Evaluation of adapted questionnaires for users and professionals allow to establish a list of requirements combining both user requests and therapeutic needs as basis for the design of the garden as well as to evaluate during the course of the project, whether the needs of the various stakeholders have been met or if adjustments are necessary.

    This presentation covers fundamental requirements and considerations for developing schedulers in airport operations. We first introduce performance and functional requirements for airport surface schedulers. Among various optimization problems in airport operations, we focus on airport surface scheduling problem, including runway and taxiway operations. We then describe a basic methodology for airport surface scheduling such as node-link network model and scheduling algorithms previously developed. Next, we explain how to design a mathematical formulation in more details, which consists of objectives, decision variables, and constraints. Lastly, we review other considerations, including optimization tools, computational performance, and performance metrics for evaluation.

  15. Seismic design and evaluation criteria based on target performance goals

    International Nuclear Information System (INIS)

    The Department of Energy utilizes deterministic seismic design/evaluation criteria developed to achieve probabilistic performance goals. These seismic design and evaluation criteria are intended to apply equally to the design of new facilities and to the evaluation of existing facilities. In addition, the criteria are intended to cover design and evaluation of buildings, equipment, piping, and other structures. Four separate sets of seismic design/evaluation criteria have been presented each with a different performance goal. In all these criteria, earthquake loading is selected from seismic hazard curves on a probabilistic basis but seismic response evaluation methods and acceptable behavior limits are deterministic approaches with which design engineers are familiar. For analytical evaluations, conservatism has been introduced through the use of conservative inelastic demand-capacity ratios combined with ductile detailing requirements, through the use of minimum specified material strengths and conservative code capacity equations, and through the use of a seismic scale factor. For evaluation by testing or by experience data, conservatism has been introduced through the use of an increase scale factor which is applied to the prescribed design/evaluation input motion

  17. DOE natural phenomenal hazards design and evaluation criteria

    International Nuclear Information System (INIS)

    It is the policy of the Department of Energy (DOE) to design, construct, and operate DOE facilities so that workers, the general public, and the environment are protected from the impacts of natural phenomena hazards (NPH). Furthermore, DOE has established explicit goals of acceptable risk for NPH performance. As a result, natural phenomena hazard (earthquake, extreme wind, and flood) design and evaluation criteria for DOE facilities have been developed based on target probabilistic performance goals. These criteria include selection of design/evaluation NPH input from probabilistic hazard curves combined with commonly practiced deterministic response evaluation methods and acceptance criteria with controlled levels of conservatism. For earthquake considerations, conservatism is intentionally introduced in specification of material strengths and capacities, in the allowance of limited inelastic behavior, and by a seismic scale factor. Criteria have been developed following a graded approach for several performance goals ranging from that appropriate for normal-use facilities to that appropriate for facilities involving hazardous or critical operations. Performance goals are comprised of qualitative expressions of acceptable behavior and of target quantitative probabilities that acceptable limits of behavior are maintained. The criteria are simple procedures but have a rigorous basis. This paper addresses DOE seismic design and evaluation criteria

    Linton, Harold E.

    2002-06-01

    The color design processes of visual artists, architects, designers, and theoreticians included in this presentation reflect the practical role of color in architecture. What the color design professional brings to the architectural design team is an expertise and rich sensibility made up of a broad awareness and a finely tuned visual perception. This includes a knowledge of design and its history, expertise with industrial color materials and their methods of application, an awareness of design context and cultural identity, a background in physiology and psychology as it relates to human welfare, and an ability to problem-solve and respond creatively to design concepts with innovative ideas. The broadening of the definition of the colorists's role in architectural design provides architects, artists and designers with significant opportunities for continued professional and educational development.

  1. Parametric Approach in Designing Large-Scale Urban Architectural Objects

    2011-04-01

    Full Text Available When all the disciplines of various science fields converge and develop, new approaches to contemporary architecture arise. The author looks towards approaching digital architecture from parametric viewpoint, revealing its generative capacity, originating from the fields of aeronautical, naval, automobile and product-design industries. The author also goes explicitly through his design cycle workflow for testing the latest methodologies in architectural design. The design process steps involved: extrapolating valuable statistical data about the site into three-dimensional diagrams, defining certain materiality of what is being produced, ways of presenting structural skin and structure simultaneously, contacting the object with the ground, interior program definition of the building with floors and possible spaces, logic of fabrication, CNC milling of the proto-type. The author’s developed tool that is reviewed in this article features enormous performative capacity and is applicable to various architectural design scales.Article in English

    Full Text Available In this study, the aesthetic design approach of architectural precedents of Safavid Architecture was examined based on users' perceptions, which were obtained by using perception questionnaire instrument. The research method included concurrent qualitative and quantitative analyses of data. Data analysis procedure was conducted through descriptive statistical analysis and by sorting thematic information for Initial categories, which were defined by the theoretical foundation. The researchers found that users' perceptions fell into two distinct groups. The first: structural honesty, expressions, identity, design feature, interaction as design values in the sense of aesthetic. The second: design principle, design concept, characteristic, minimalism, and style as an attribute. Such findings revealed how Safavid architectural concepts were aesthetically integrated into the diversity aspects of its architectural precedents.

    Full Text Available This paper describes an open educational resources (OER architecture framework that would bring significant improvements in a well-structured and systematic way to the educational practices of distance education institutions of India. The OER architecture framework is articulated with six dimensions: pedagogical, technological, managerial, academic, financial, and ethical. These dimensions are structured with the component areas of relevance: IT infrastructure services, management support systems, open content development and maintenance, online teaching-learning, and learner assessment and evaluation of the OER architecture framework. An OER knowledge and information base, including a web portal, is proposed in the form of a series of knowledge repositories. This system would not only streamline the delivery of distance education but also would enhance the quality of distance learning through the development of high quality e-content, instructional processes, course/programme content development, IT infrastructure, and network systems. Thus the proposed OER architecture framework when implemented in the distance education system (DES of India would improve the quality of distance education and also increase its accessibility in a well-organised and structured way.

    Science.gov (United States)

    Gullichsen, E.; Chang, E.

    The mathematician-architect Christopher Alexander has devised a theory of objective architectural design. He believes that all architectural forms can be described as interacting patterns, all possible relationships of which are governed by generative rules. These form a pattern language' capable of generating forms appropriate for a given environmental context. The complexity of interaction among these rules leads to difficulties in their representation by conventional methods. Here, a Prolog-based expert system is presented which implements Alexander's design methodology to produce perspective views of partially and fully differentiated 3-dimensional architectural forms.

    2015-08-01

    Full Text Available Root of the word Gothic comes from a German tribe which lives in region of the Gotland of Scandinavia. Gothic period is a movement which ends the Midde Age and opens Renaissance. Alth ough seen in all branches of the art, Gothic is widely a style of architecture. Having been originated from the Roman architecture, Gothic Architecture come out in the second half of the 12th century and continued its existence until the half of the 16th c entury when classical architecture come out. In Europe, Gothic painting, sculpture and architecture were dominant and preserved its popularity until the Renaissance. Fashion means all the temporary new styles which come out in a certain period of time with the desires of dressing up, being different, wearing the most desirable. Although seen as two different design field, when we examine closely, we can see that fashion and architecture has many common point from the past to present. As man is the common po int of this two field, they naturally affect each other. Gothic architecture inspired clothing designs, which is enough to show how much they affected each other. In this study, our purpose is to reveal effects of the Gothic architecture on the clothing d esigns. The style used in the Gothic period architecture and models and styles in clothing designs was presented with the help of table of specification. According to this, both fields' sharing common aesthetic concern and same theoritic and ideologic bas e was accompanied by stylistic and structural similarities accordingly. Designers in this two different fields turned even to themselves for inspiration and technical strategy. Environmental and cultural factors affect both fashion designers and architects . When seen as a part of historical process, clothes and buildings with their important cultural and economic conditions are priceless anthropological buildings which show technological developments within the period.

  19. An optimal structural design algorithm using optimality criteria

    1976-01-01

    An algorithm for optimal design is given which incorporates several of the desirable features of both mathematical programming and optimality criteria, while avoiding some of the undesirable features. The algorithm proceeds by approaching the optimal solution through the solutions of an associated set of constrained optimal design problems. The solutions of the constrained problems are recognized at each stage through the application of optimality criteria based on energy concepts. Two examples are described in which the optimal member size and layout of a truss is predicted, given the joint locations and loads.

  20. The constraints satisfaction problem approach in the design of an architectural functional layout

    Science.gov (United States)

    Zawidzki, Machi; Tateyama, Kazuyoshi; Nishikawa, Ikuko

    2011-09-01

    A design support system with a new strategy for finding the optimal functional configurations of rooms for architectural layouts is presented. A set of configurations satisfying given constraints is generated and ranked according to multiple objectives. The method can be applied to problems in architectural practice, urban or graphic design-wherever allocation of related geometrical elements of known shape is optimized. Although the methodology is shown using simplified examples-a single story residential building with two apartments each having two rooms-the results resemble realistic functional layouts. One example of a practical size problem of a layout of three apartments with a total of 20 rooms is demonstrated, where the generated solution can be used as a base for a realistic architectural blueprint. The discretization of design space is discussed, followed by application of a backtrack search algorithm used for generating a set of potentially 'good' room configurations. Next the solutions are classified by a machine learning method (FFN) as 'proper' or 'improper' according to the internal communication criteria. Examples of interactive ranking of the 'proper' configurations according to multiple criteria and choosing 'the best' ones are presented. The proposed framework is general and universal-the criteria, parameters and weights can be individually defined by a user and the search algorithm can be adjusted to a specific problem.

    International Nuclear Information System (INIS)

    In the 80's a new architecture design and implementation style has appeared: the RISC style. It proposes an overall view of the system were the processor is included. For each function, an extensive analysis has to be performed in order to evaluate the advantages and disadvantages that hardware and software introduce in the design. An optimum design involved an agreement between both levels and has to take into account cost, performance, and technological factors. In this paper, the main features of this new architecture design style are presented. (Author)

  6. A simple framework for integrated design of complex architectural forms

    CERN Document Server

    Svoboda, Ladislav; Zeman, Jan; Kurilla, Lukáš

    2012-01-01

    This paper presents preliminary results of a newly developed methodology and a software tool for parametric design of complex architectural objects, so called digital or algorithmic forms. In order to provide a maximally flexible solution, the proposed design philosophy yields two open source utilities Donkey and MIDAS written in Grashopper algorithm editor and C++, respectively, that are to be linked with a scripting-based architectural modellers Rhinoceros(C), AutoCAD(C) and the open source Finite Element solver OOFEM. The emphasis is on the mechanical response of designed objects in order to provide architects with a consistent learning framework and wise insight into structural behaviour of their artworks. As demonstrated on several case studies, the combination of the utilities may handle objects of considerable structural complexity and boosts the algorithmic architectural design in terms of accelerating the process of finding procedural design parameters from orders of weeks to days or hours.

(2). What minimum seismic margin is acceptable? (3) Given the decisions made under Issues 1 and 2, at what annual frequency of exceedance should the Safe Shutdown Earthquake ground motion be defined? (4) What seismic design criteria should be established to reasonably achieve the seismic margin defined under Issue 2? The first issue is purely a policy decision and is not addressed in this paper. Each of the other three issues are addressed. Issues 2 and 3 are integrally tied together so that a very large number of possible combinations of responses to these two issues can be used to achieve the target goal defined under Issue 1. Section 2 lays out a combined approach to these two issues and presents three potentially attractive combined resolutions of these two issues which reasonably achieves the target goal. The remainder of the paper discusses an approach which can be used to develop seismic design criteria aimed at achieving the desired seismic margin defined in resolution of Issue 2. Suggestions for revising existing seismic design criteria to more consistently achieve the desired seismic margin are presented

    2012-04-01

    Full Text Available C4ISR framework describes architecture in three views of information architecture and defines a set of products, which are main outputs of enterprise architecture design. Formats and templates, which are presented for C4ISR products, cannot describe uncertainty in process or data. Meanwhile, uncertainty in many information systems is unavoidable and using the concept of fuzzy numbers in architecture design helps architects handle uncertainty in process and data of organization. In this paper, we present a new template based on fuzzy-UML concept for some of C4ISR products such as Logical Data Model (OV-7, Operational Event/Trace Description (OV-6c and Systems Event/Trace Description (SV-10c. To explain further, fictional Fast Pass system used at OilCo gas stations is used to demonstrate details of our proposed model.

  17. A distributed software architecture design framework based on attributed grammar

    JIA Xiao-lin; QIN Zheng; HE Jian; YU Fan

    2005-01-01

    Software architectures shift the focus of developers from lines-of-code to coarser-grained architectural elements and their overall interconnection structure. There are, however, many features of the distributed software that make the developing methods of distributed software quite different from the traditional ways. Furthermore, the traditional centralized ways with fixed interfaces cannot adapt to the flexible requirements of distributed software. In this paper, the attributed grammar (AG) is extended to refine the characters of distributed software, and a distributed software architecture description language (DSADL) based on attributed grammar is introduced, and then a model of integrated environment for software architecture design is proposed. It can be demonstrated by the practice that DSADL can help the programmers to analyze and design distributed software effectively, so the efficiency of the development can be improved greatly.

  18. Shape grammar in contemporary architectural theory and design

    2012-01-01

    Full Text Available In the past decade, digital technologies had a great impact on contemporary architectural practice, design and theory. CAD/CAM technologies opened up new opportunities by allowing design and production of complex geometric shapes. One of the first applications of computational process in architecture was based on using shape grammars, a rule-based expert systems in artificial intelligence generating geometric shapes. Early applications of shape grammars in art and architecture started shortly after its invention during the 70ies and 80ies of the XX century, however, their potential as a generative design tool still has not been fully exploited in practice. Despite their popularity in academic circles, shape grammars have not found a widespread place/usage in computer aided architectural design. Role of shape grammar as a generative design and analysis tool and their influence on contemporary architectural design and theory are examined in this paper. Also, new and ongoing issues concerning shape grammars are discussed in order to indicate further directions of their usage. [Projekat Ministarstva nauke Republike Srbije

    Significant developments have taken place over the past few years in the area of vehicular communication (VC) systems. Now, it is well understood in the community that security and protection of private user information are a prerequisite for the deployment of the technology. This is so, precisely because the benefits of VC systems, with the mission to enhance transportation safety and efficiency, are at stake. Without the integration of strong and practical security and privacy enhancing mechanisms, VC systems could be disrupted or disabled, even by relatively unsophisticated attackers. We address this problem within the SeVeCom project, having developed a security architecture that provides a comprehensive and practical solution. We present our results in a set of two papers in this issue. In this first one, we analyze threats and types of adversaries, we identify security and privacy requirements, and we present a spectrum of mechanisms to secure VC systems.

    M.Upendra Kumar

    2010-04-01

    Full Text Available System Security Architecture from a software engineering viewpoint imposes that strong security must be a guiding principle of the entire software development process. It describes a way to weave security into systems architecture, and it identifies common patterns of implementation found in most security products. The security and software engineering communities must find ways to develop software correctly in a timely and cost-effective fashion. There’s no substitute for working software security as deeply into the evelopment process as possible. System designers and developers must take a more proactive role in building secure software. The root of most security problems is software that fails in unexpected ways whenunder attack. The enforcement of security at the design phase canreduce the cost and effort associated with the introduction of security during implementation. At the architecture level a systemmust be coherent and present unified security architecture that takes into account security principles (such as the least privilege. In this paper we want to discuss about different facets of security as applicable to Service Oriented Architectures (SOA Security Architecture implementations. First we examine the securityrequirements and its solution mechanisms. In the context of WebServices, the predominant SOA implementation standard has a crucial role to play. The Web Services architecture is expected to play a prominent role in developing next generation distributed systems. Building dependable systems based on web services architecture is a major research issue being discussed. Finally, we provide a case study of Web Services Security Architecture, enhancing its security pertaining to Web 2.0 AJAX (Asynchronous JavaScript and XML and its Security encryption of data using MD5algorithm.

    Full Text Available In architectural discourse, it is possible to notice a rising interest in building skin configurations which promise to help minimizing the loss of energy while maximizing its gain. In parallel, it is possible to see that the use of double-skin glass facades globally pervades. All over the world double-skin facade applications multiply day by day. This technology is still quite new in Turkey and it is not possible to find many applications or researches done on this subject. For this reason, architects and engineers should be focused on the designs solutions providing energy savings. The design of DSF depends on various architectural decisions. In this study, effective design decision parameters on energy performance of DSF systems will be discussed in a comprehensive way in architectural perspective by reviewing previous studies.

    1990-01-01

    Passenger comfort is of great importance in most transport vehicles. For instance, in the new generation of regional turboprop aircraft, a low noise level is vital to be competitive on the market. The possibilities to predict noise levels analytically has improved rapidly in recent years. This will make it possible to take acoustic design criteria into account in early project stages. The development of the ASKA FE-system to include also acoustic analysis has been carried out at Saab Aircraft Division and the Aeronautical Research Institute of Sweden in a joint project. New finite elements have been developed to model the free fluid, porous damping materials, and the interaction between the fluid and structural degrees of freedom. The FE approach to the acoustic analysis is best suited for lower frequencies up to a few hundred Hz. For accurate analysis of interior cabin noise, large 3-D FE-models are built, but 2-D models are also considered to be useful for parametric studies and optimization. The interest is here focused on the introduction of an acoustic design criteria in the general structural optimization system OPTSYS available at the Saab Aircraft Division. The first implementation addresses a somewhat limited class of problems. The problems solved are formulated: Minimize the structural weight by modifying the dimensions of the structure while keeping the noise level in the cavity and other structural design criteria within specified limits.

  1. Architecture, Infrastructure, and Broadband Civic Network Design: An Institutional View

    Science.gov (United States)

    Venkatesh, Murali; Chango, Mawaki

    Cultural values frame architectures, and architectures motivate infrastructures — by which we mean the foundational telecommunications and Internet access services that software applications depend on. Design is the social process that realizes architectural elements in an infrastructure. This process is often a conflicted one where transformative visions confront the realities of entrenched power, where innovation confronts pressure from institutionalized interests and practices working to resist change and reproduce the status quo in the design outcome. We use this viewpoint to discuss design aspects of the Urban-net, a broadband civic networking case. Civic networks are embodiments of distinctive technological configurations and forms of social order. In choosing some technological configurations over others, designers are favoring some social structural configurations over alternatives. To the extent that a civic network sets out to reconfigure the prevailing social order (as was the case in the Urban-net project considered here), the design process becomes the arena where challengers of the prevailing order encounter its defenders. In this case, the defenders prevailed and the design that emerged was conservative and reproduced the status quo. What steps can stakeholders take so that the project’s future development is in line with the original aim of structural change? We outline two strategies. We argue the importance of articulating cultural desiderata in an architecture that stakeholders can use to open up the infrastructure to new constituents and incremental change. Next, we argue the importance of designing the conditions of design. The climate in which social interactions occur can powerfully shape design outcomes, but this does not usually figure in stakeholders’ design concerns.

    Full Text Available Cities in 21st century are losing identity due to globalization and rapid urbanism. However, great architectural buildings like Sultan Hassan Mosque Complex show us that great architectural wonders can keep this identity and can affect positively in society’s life. The simple aim of this study is to investigate the relationship between architectural features and Islamic meanings in modern world through studying the past. The study is mainly based on two main sources of data, literature review regarding historical part and site visit dealing with discussion of architectural features, uses and effect on surroundings society. Based on these sources, analysis was made based on matrix relationship between two sets of criteria, architectural parts (design, usage, location, artistic features, and mosque significance in Islam (prayer house, community center, center of knowledge, meeting place for shoura. Findings proved the existence of consequent relationship between Islam and architecture, as Islamic principles affect the design of the mosque in religious, social, and service aspects. Alternatively, architectural building satisfies all Muslim needs. This dual effect situation shapes recommend-dations like enhancement of the multidimensional use of the mosque, strengthen the community service role of the mosque, and developing design of modern mosques to fulfill Muslim requirements with 21st century measures and also endorse Islamic values through architecture.

  15. Review of structural design criteria for heat exchanger tube sheets

    International Nuclear Information System (INIS)

    Survey of various tube sheet design criteria was made in order to establish structural design criterion for the high-temperature tube sheet of the Intermediate Heat Exchanger of the Experimental Multipurpose VHTR. From this survey, it was found that there is no appropriate design criterion for the IHX high-temperature tube sheet among those tube sheet design criteria. However, the stress analysis method of tube sheet given in ASME Boiler and Pressure Vessel Code Section III Appendix A-8000 is considered to be useful, which is two dimensional stress analysis method by replacing the perforated region of tube sheet to the equivalent solid plate. Concerning this method given in A-8000, recently, T.Slot et al. have proposed more accurate effective elastic constants than those given in A-8000. Then, it was examined what degree of the difference there is between the stress analysis results obtained from the data given in A-8000 and those from the data proposed by T.Slot et al. (author)

  16. Evaluation of seismic criteria used in design of INEL facilities

    International Nuclear Information System (INIS)

    This report provides the results of an independent evaluation of seismic studies that were made to establish the seismic acceleration levels and the response spectra used in the design of vital facilities at Idaho National Engineering Laboratory. A comparison of the procedures used to define the seismic acceleration values and response spectra at INEL with the requirements of the Nuclear Regulatory Commission showed that additional geologic studies would probably be required in order to fulfill NRC regulations. Recommendations are made on justifiable changes in the acceleration values and response spectra used at INEL. The geologic, geophysical, and seismological studies needed to provide a better understanding of the tectonic processes in the Snake River plains and the surrounding region are identified. Both potential and historical acceleration values are evaluated on a probability basis to permit a risk assessment approach to the design of new facilities and facility modifications. Studies conducted to develop seismic criteria for the design of the Loss of Fluid Test reactor and the New Waste Calcining Facility were selected as typical examples of criteria development previously used in the design of INEL facilities

    2009-01-01

    The cost of the central register file and the size of the program code limit the scalability of very long instruction word (VLIW) processors with increasing numbers of functional units. This paper presents the architectural design of a six-way VLIW digital signal processor (DSP) with clustered register files. The archi-tecture uses a variable length instruction set and supports dynamic instruction dispatching. The one-level memory system architecture of the processor includes 16-KB instruction and data caches and 16-KB in-struction and data on-chip RAM. A compiler based on the Open64 was developed for the system. Evalua-tions show that the processor is suitable for high performance applications with a high code density and small program code size.

  2. Electromagnetic Vibration Energy Harvesting Devices Architectures, Design, Modeling and Optimization

    2012-01-01

    Electromagnetic vibration transducers are seen as an effective way of harvesting ambient energy for the supply of sensor monitoring systems. Different electromagnetic coupling architectures have been employed but no comprehensive comparison with respect to their output performance has been carried out up to now. Electromagnetic Vibration Energy Harvesting Devices introduces an optimization approach which is applied to determine optimal dimensions of the components (magnet, coil and back iron). Eight different commonly applied coupling architectures are investigated. The results show that correct dimensions are of great significance for maximizing the efficiency of the energy conversion. A comparison yields the architectures with the best output performance capability which should be preferably employed in applications. A prototype development is used to demonstrate how the optimization calculations can be integrated into the design–flow. Electromagnetic Vibration Energy Harvesting Devices targets the design...

    Full Text Available Service Orientation Engineering (SOE (using Web Services and Agile modeling software development presents promising solutions for contemporary software development projects to deal effectively withchallenges in increasingly turbulent business environments typified by unpredictable markets, changing customer requirements, pressures of even shorter time to deliver, and rapidly advancing informationtechnologies. Web Services Security Architectures have three layers, as provided by NIST standard: Web Service Layer, Web Services Framework Layer (.NET or J2EE, and Web Server Layer. In services oriented web services architecture, business processes are executed as a composition of services, which can suffer from vulnerabilities pertaining to secure data access and protecting code of Web Services. The goal of the Web services security architecture is to summary out the details of message-level security from the mainstream business logic, with a focus on Web Service contract design and versioning for SOA. Service oriented web services architectures impose additional analysis complexity as they provide much flexibility and frequentchanges with in orchestrated processes and services. In this paper, we discuss about developing dependable solutions for Web Services Security Architectures using Agile Layered security architectures in terms of Privacy requirements. All this research is motivated by Secure Service Oriented Analysis and Design research domain. We initially validate this by a BPEL Editor using GWT for RBAC and Privacy. Finally a real world case study is implemented using J2EE, for validating our approach. Secure Stock Exchange System using Web Services is to automate the stock exchange works, and can help user make the decisions when it comes to investment.

    Full Text Available Despite the current evolution of several tools that help understanding, representing and constructing a better awareness of sound and more generally the sensory qualities of the built environment, the integration of sonic dimension in the ordinary architectural production remains difficult. Sonic dimension is still undervalued considered as an accessory or as a second dimension of the space. Till now, the sonic quality doesn’t have its legitimacy in the architectural and urban thinking except in specific situations where designer should solve certain problems of noise and propagation. Therefore, we should find the appropriate qualitative criteria of the architectural elements that don’t only integrate the perceptive aspects but also the action. In this sense, we shall present an experimentation that has been elaborated to clarify the relationship between sound and movement or sound and action in order to design spatial architectural elements. How can we identify the sonic role during the spatial experiment and explore the different corporal and movement modalities that emerge by hearing? We postulate that the actions potentials that emerge in a sonic context must be considered as an alternative that can modulate the environment in space and time[1].

    1981-01-01

    Procedures and solution strategies are described to solve the conventional structural optimization problem using the Lagrange multiplier technique. The multipliers, obtained through solution of an auxiliary nonlinear optimization problem, lead to optimality criteria to determine the design variables. It is shown that this procedure is essentially equivalent to an alternative formulation using a dual method Lagrangian function objective. Although mathematical formulations are straight-forward, successful applications and computational efficiency depend upon execution procedure strategies. Strategies examined, with application examples, include selection of active constraints, move limits, line search procedures, and side constraint boundaries.

  10. Architectural design of heterogeneous metallic nanocrystals--principles and processes.

    CONSPECTUS: Heterogeneous metal nanocrystals (HMNCs) are a natural extension of simple metal nanocrystals (NCs), but as a research topic, they have been much less explored until recently. HMNCs are formed by integrating metal NCs of different compositions into a common entity, similar to the way atoms are bonded to form molecules. HMNCs can be built to exhibit an unprecedented architectural diversity and complexity by programming the arrangement of the NC building blocks ("unit NCs"). The architectural engineering of HMNCs involves the design and fabrication of the architecture-determining elements (ADEs), i.e., unit NCs with precise control of shape and size, and their relative positions in the design. Similar to molecular engineering, where structural diversity is used to create more property variations for application explorations, the architectural engineering of HMNCs can similarly increase the utility of metal NCs by offering a suite of properties to support multifunctionality in applications. The architectural engineering of HMNCs calls for processes and operations that can execute the design. Some enabling technologies already exist in the form of classical micro- and macroscale fabrication techniques, such as masking and etching. These processes, when used singly or in combination, are fully capable of fabricating nanoscopic objects. What is needed is a detailed understanding of the engineering control of ADEs and the translation of these principles into actual processes. For simplicity of execution, these processes should be integrated into a common reaction system and yet retain independence of control. The key to architectural diversity is therefore the independent controllability of each ADE in the design blueprint. The right chemical tools must be applied under the right circumstances in order to achieve the desired outcome. In this Account, after a short illustration of the infinite possibility of combining different ADEs to create HMNC design

  11. Development of nuclear design criteria for neutron spallation sources

    International Nuclear Information System (INIS)

    Spallation neutron sources allow obtaining high neutronic flux for many scientific and industrial applications. In recent years, several proposals have been made about its use, notably the European Spallation Source (ESS), the Japanese Spallation Source (JSNS) and the projects of Accelerator-Driven Subcritical reactors (ADS), particularly in the framework of EURATOM programs. Given their interest, it seems necessary to establish adequate design basis for guiding the engineering analysis and construction projects of this kind of installations. In this sense, all works done so far seek to obtain particular solutions to a particular design, but there has not been any general development to set up an engineering methodology in this field. In the integral design of a spallation source, all relevant physical processes that may influence its behaviour must be taken into account. Neutronic aspects (emitted neutrons and their spectrum, generation performance..), thermomechanical (energy deposition, cooling conditions, stress distribution..), radiological (spallation waste activity, activation reactions and residual heat) and material properties alteration due to irradiation (atomic displacements and gas generation) must all be considered. After analysing in a systematic manner the different options available in scientific literature, the main objective of this thesis was established as making a significant contribution to determine the limiting factors of the main aspects of spallation sources, its application range and the criteria for choosing optimal materials. To achieve this goal, a series of general simulations have been completed, covering all the relevant physical processes in the neutronic and thermal-mechanical field. Finally, the obtained criteria have been applied to the particular case of the design of the spallation source of subcritical reactors PDX-ADS and XT-ADS. These two designs, developed under the European R and D Framework Program, represent nowadays

    2009-01-01

    This text presents a cognitive-psychology analysis of spontaneous, co-speech gestures in a face-to-face architectural design meeting (A1 in DTRS7). The long-term objective is to formulate specifications for remote collaborative-design systems, especially for supporting the use of different semiotic modalities (multi-modal interaction). According to their function for design, interaction, and collaboration, we distinguish different gesture families: representational (entity designating or specifying), organisational (management of discourse, interaction, or functional design actions), focalising, discourse and interaction modulating, and disambiguating gestures. Discussion and conclusion concern the following points. It is impossible to attribute fixed functions to particular gesture forms. "Designating" gestures may also have a design function. The gestures identified in A1 possess a certain generic character. The gestures identified are neither systematically irreplaceable, nor optional accessories to speech...

  15. Failsafe design criteria for computer based reactor protection systems

    International Nuclear Information System (INIS)

    The design criteria proposed are an extrapolation of the failsafe mode of operation used in the UK in hardwired reactor protection systems. This is achieved by making the operational condition of the reactor dependent upon an energetic state of the protection system components. An important objective of the proposed design criteria is to eliminate, or at least to minimize, the need for a failure-mode-and-effect-analysis (FMEA) of the computer software. This demands some well defined but simple constraints upon the way in which data are stored in the computers, but the objective is achieved almost entirely by hardware properties of the system. The first of these is the systematic use of hardwired test inputs which cause transient excursions into the tripped state in a uniquely ordered but easily recognizable sequence. The second is the use of hardwired pattern recognition logic which generates a dynamic healthy stimulus for the shutdown actuators only in response to the unique sequence formed by the hardwired input signal pattern. It therefore detects abnormal states of any of the system inputs, software errors, wiring errors and hardware failures. This hardwired logic is conceptually simple, failsafe, and is amenable to simple FMEA. (U.K.)

  16. Functional design criteria for the retained gas sampler system

    International Nuclear Information System (INIS)

    A Retained Gas Sampler System (RGSS) is being developed to capture and analyze waste samples from Hanford Flammable Gas Watch List Tanks to determine both the quantity and composition of gases retained in the waste. The RGSS consists of three main components: the Sampler, Extractor, and Extruder. This report describes the functional criteria for the design of the RGSS components. The RGSS Sampler is based on the WHC Universal Sampler design with modifications to eliminate gas leakage. The primary function of the Sampler is to capture a representative waste sample from a tank and transport the sample with minimal loss of gas content from the tank to the laboratory. The function of the Extruder is to transfer the waste sample from the Sampler to the Extractor. The function of the Extractor is to separate the gases from the liquids and solids, measure the relative volume of gas to determine the void fraction, and remove and analyze the gas constituents

    This paper is based on i) the recent input of the authors for the Underground Containment Sub-Section of the Seismic Task Group Report of the ASCE Committee for Nuclear Structures and Materials, and ii) parametric studies carried out by the first author on the principal undergound concepts. The extensive work on aseismic design of above-ground reactors and recent studies on missile impact effects, aircraft impact, blast effects due to chemical explosions, reactor core melt-down and tornadoes indicate the advantages of underground siting with inherent general reduction to complexity of seismic amplification and benefits of structural and biological integrity. Other advantages are possibilities of urban siting, ecological considerations, reduced effects on the landscape, ability to design three-dimensionally, separation of component facilities, support capability to equipment, reduced power transmission costs, increased number of acceptable units and power capability from a single location, and reduction of decommissioning problems. In view of the limited actual experience in the structural design of underground containments (only four European reactors), the proposals are based on a) the transposition of applicable design specifications, constraints and criteria from existing surface nuclear power plants to underground, and b) the use of many years of experience in the structural design of large underground cavities and cavity complexes for other purposes such as mining, hydropower stations etc. (Auth.)

    2016-01-01

    The book presents the proceedings of Rob/Arch 2016, the third international conference on robotic fabrication in architecture, art, and design. The work contains a wide range of contemporary topics, from methodologies for incorporating dynamic material feedback into existing fabrication processes, to novel interfaces for robotic programming, to new processes for large-scale automated construction. The latent argument behind this research is that the term ‘file-to-factory’ must not be a reductive celebration of expediency but instead a perpetual challenge to increase the quality of feedback between design, matter, and making.

  10. Building information modeling in the architectural design phases

    DEFF Research Database (Denmark)

    Hermund, Anders

    The overall economical benefits of Building Information Modeling are generally comprehensible, but are there other problems with the implementation of BIM as a formulized system in a field that ultimately is dependant on a creative input? Is optimization and economic benefit really contributing...... with an architectural quality? In Denmark the implementation of the digital working methods related to BIM has been introduced by government law in 2007. Will the important role of the architect as designer change in accordance with these new methods, and does the idea of one big integrated model...... represent a paradox in relation to designing? The BIM mindset requires changes on many levels....

  12. Alternate architectures and technologies for Intelsat type DSI design

    Science.gov (United States)

    Keelty, J. M.; Hatzigeorgiou, S.

    1983-01-01

    The architectural choices in the unit design have to do with the amount of storage and the type of storage in the unit, the type of high-speed interface, the type of echo-protection features, the FEC encoding, and the degree of human interface for testing and maintenance. Since the interpolation process takes time, the unit is by necessity memory-oriented, and an efficient choice of memory architecture is cardinal. The two principal design choices are referred to as 'oorder and storage' and 'storage and order.' Store-and-order implies storage of data on all received channels (regardless of whether they are to be processed), followed by data routing for selected channels. Order-and-store implies immediate selection of the traffic to be processed. The architecture is also affected by the choice of interface between the DSI (digital speech interpolation) and the 'satellite' side equipment. Although the principal choice is between word- and bit-oriented data transmission, tradeoffs exist involving handshaking for control signals as well.

  13. Do Performance-Based Codes Support Universal Design in Architecture?

    Grangaard, Sidse; Frandsen, Anne Kathrine

    2016-01-01

    The research project 'An analysis of the accessibility requirements' studies how Danish architectural firms experience the accessibility requirements of the Danish Building Regulations and it examines their opinions on how future regulative models can support innovative and inclusive design - Universal Design (UD). The empirical material consists of input from six workshops to which all 700 Danish Architectural firms were invited, as well as eight group interviews. The analysis shows that the current prescriptive requirements are criticized for being too homogenous and possibilities for differentiation and zoning are required. Therefore, a majority of professionals are interested in a performance-based model because they think that such a model will support 'accessibility zoning', achieving flexibility because of different levels of accessibility in a building due to its performance. The common understanding of accessibility and UD is directly related to buildings like hospitals and care centers. When the objective is both innovative and inclusive architecture, the request of a performance-based model should be followed up by a knowledge enhancement effort in the building sector. Bloom's taxonomy of educational objectives is suggested as a tool for such a boost. The research project has been financed by the Danish Transport and Construction Agency. PMID:27534292

    Contemporary lectures in undergraduate engineering courses typically focus on teaching major technical knowledge-based theories in a limited time. Therefore, most lectures do not allow the students to gain understanding of how the theories are applied, especially in Naval Architecture and Ocean Engineering departments. Shipyards require students to acquire practical ship design skills in undergraduate courses. To meet this requirement, two lectures are organized by the authors; namely, "Planning Procedure of Naval Architecture & Ocean Engineering" (PNAOE) and "Innovative Ship Design" (ISD). The concept of project-based and collaborative learning is applied in these two lectures. In the PNAOE lecture, sophomores receive instruction in the designing and building of model ships, and the students' work is evaluated in a model ship contest. This curriculum enables students to understand the concepts of ship design and production. In the ISD lecture, seniors learn how to develop their creative ideas about ship design and communicate with members of group. They are encouraged to cooperate with others and understand the ship design process. In the capstone design course, students receive guidance to facilitate understanding of how the knowledge from their sophomore or junior classes, such as fluid mechanics, statics, and dynamics, can be applied to practical ship design. Students are also encouraged to compete in the ship design contest organized by the Society of Naval Architects of Korea. Moreover, the effectiveness of project-based and collaborative learning for enhancing interest in the shipbuilding Industry and understanding the ship design process is demonstrated by citing the PNAOE and ISD lectures as examples.

    Advances in web technologies have driven massive content uploads and requests that can be identified by the increased usage of multimedia web and social web services. This situation enforces the content providers to scale their infrastructure in order to cope with the extra provisioning of network traffic, storage and other resources. Since the complexity and cost factors in scaling the infrastructure exist, we propose a novel solution for providing and delivering contents to clients by introducing a brokered collaborative content delivery system. The architectural design of this system leverages content redundancy and content distribution mechanisms in other content providers to deliver contents to the clients. With the recent emergence of cloud computing, we show that this system can also be adopted to run on the cloud. In this paper, we focus on a brokering scheme to mediate user requests to the most appropriate content provider based on a ranking system. The architecture provides a novel Global Rank Value...

    2014-01-01

    Full Text Available Platinum and Pt alloy nanoparticles supported on carbon are the state of the art electrocatalysts in proton exchange membrane fuel cells. To develop a better understanding on how material design can influence the degradation processes on the nanoscale, three specific Pt/C catalysts with different structural characteristics were investigated in depth: a conventional Pt/Vulcan catalyst with a particle size of 3–4 nm and two Pt@HGS catalysts with different particle size, 1–2 nm and 3–4 nm. Specifically, Pt@HGS corresponds to platinum nanoparticles incorporated and confined within the pore structure of the nanostructured carbon support, i.e., hollow graphitic spheres (HGS. All three materials are characterized by the same platinum loading, so that the differences in their performance can be correlated to the structural characteristics of each material. The comparison of the activity and stability behavior of the three catalysts, as obtained from thin film rotating disk electrode measurements and identical location electron microscopy, is also extended to commercial materials and used as a basis for a discussion of general fuel cell catalyst design principles. Namely, the effects of particle size, inter-particle distance, certain support characteristics and thermal treatment on the catalyst performance and in particular the catalyst stability are evaluated. Based on our results, a set of design criteria for more stable and active Pt/C and Pt-alloy/C materials is suggested.

    The transportation research committee of JRS (Japanese Rocket Society) has begun conceptual design of vertical takeoff and landing fully reusable SSTO (Single Stage to Orbit) rocket type vehicle as a standard vehicle model for space tourism. The design criteria of the vehicle have paid most attention to the requirements of service to meet space tour amusement. The standard vehicle, which has 22m body length and weighs about 550 tons at takeoff, can provide attractive tours of 24 hours maximum for 50 passengers into the low earth orbit with a variety of space flight pleasures such as experience of weightlessness and earth sightseeing. Within the reach of our near future rocket technology, the design utilizes MMC, CF/Epy and Ti/Mw advanced materials. The twelve LOX/LH2 engines consist of two nozzle types, which can be throttled and gimbaled during the whole mission time, perform vertical launch and tail-first reentry to final landing associated with aerodynamic control of body flaps within tolerable acceleration acting on passengers.

  20. Development of structural design criteria for internals of LWR

    International Nuclear Information System (INIS)

    Full text of publication follows. Some operating conditions of LWR (PWR, VVER type) internals, such as irradiation, exposure in water, high temperature, static and cyclic stresses, as well as trends toward extension of the design service life of operating and newly developed NPPs to 60 years, dictate the need for providing relevant regulations for the reactor internals. Russian regulations PNAEG for NPP equipment and pipelines do not cover VVER internals, wherefore the design, manufacture and operation of the latter are based on the existing experience, which have not been transferred and specified into regulatory terms. There are not known codes or recommendations for the lifetime and structural integrity assessment or PWR and BWR internals. The existing regulatory rules that can be found in ASME and RCC-M codes refer to the core supports, but leave out the conditions specific to the internals, which give rise to metal degradation mechanisms, such as radiation-induced swelling and creep, fatigue under irradiation, radiation induced loss of work hardening capability, embrittlement effect, vibration, wear, etc. The rules for accounting of LWR internals working conditions and specific of their design are under development in ENES. Effect of irradiation on tensile behaviour, fracture toughness, fatigue and swelling were analysed on the bases of available data of solution annealed austenitic steels, mainly of 316, 304 and 321 types (the last one is the AISI designation of Russian grade X18H10T used for VVER internals). Equations for the best fit of available experimental data were generated for the mentioned above properties that allow to specify design allowable for irradiated austenitic steels used for PRI. Criteria for assessment of structural integrity of reactor components subjected to irradiation are also discusses in the paper. (authors)

    Robotic automation has become ubiquitous in the modern manufacturing landscape, spanning an overwhelming range of processes and applications-- from small scale force-controlled grinding operations for orthopedic joints to large scale composite manufacturing of aircraft fuselages. Smart factories, seamlessly linked via industrial networks and sensing, have revolutionized mass production, allowing for intelligent, adaptive manufacturing processes across a broad spectrum of industries. Against this background, an emerging group of researchers, designers, and fabricators have begun to apply robotic technology in the pursuit of architecture, art, and design, implementing them in a range of processes and scales. Coupled with computational design tools the technology is no longer relegated to the repetitive production of the assembly line, and is instead being employed for the mass-customization of non-standard components. This radical shift in protocol has been enabled by the development of new design to production...

    Full Text Available The expansion of the Internet has changed the way business models are conceived. In addition, several e-commerce models were built for a wide range of applications. Due to the proliferation of advanced and efficient techno-logies, individuals are using more interactive and rich Internet applications. At the same time, Multi-agent Systems have shown their efficiency to solve complex problems and to deal with situations where the collaboration between heterogeneous agents is needed. Collaboration among auton-omous agents represents an important and challenging field of study, since most of the business models can be adopted and implemented according to this architecture. In this paper, we will develop a collaborative architecture for 3D design, based on the collaboration of an agent and a human. With the guidance of the agent, the user will parametrically design the product using a 3D environment. After the design phase, the agent will submit the design as a contract. A mediator will collect the submitted model(s, and a final model will be chosen based on a particular strategy. We also investigate the possible representations of a specific type of contracts as to represent 3D objects. We note the existing interplay between different types of attributes and therefore establish new assumptions related to general contracts modeling

  6. Kinetic and empirical design criteria for constructed wetlands

    International Nuclear Information System (INIS)

    A study was conducted to demonstrate the capabilities of wetlands as long-term, self-sustaining natural systems for the treatment of large quantities of waste water released from tailings ponds after mine abandonment. Constructed wetlands were built and planted with aquatic plants. The experimental design included three replicate trenches for each of two treatment systems. The objective of the research was to assess the optimum contaminant loading rates which would result in an acceptable quality of the effluent water. Using empirical data (i.e., hydrocarbon loading rates versus effluent quality), the optimal range of hydrocarbon loading was 5 to 25 gTEH/m2/month. Using more conservative kinetic data (i.e. microbial mineralization rates), the range of optimal treatment effectiveness was 9.6 to 13.2 gTEH/m2/month. The two design criteria methodologies were calculated using two independent analytical methods. The similarity in results was judged to be a confirmation of their accuracy. 20 refs., 5 figs

This study examines the reflections on interior surfaces, in terms of benefits from appropriate utilization of natural light on interiors. In part one, the topic of light permeability is introduced with respect to definition of transparency, related supporting definitions and its physical, psychological effects. In part two, the concept of transparency in architectural constructions is examined based on historical development. Finally, it is evident that the psychological factors must be also taken into consideration and necessary to control the transparency proportions in buildings, in parallel, the level of illumination.

    2015-12-24

    Tandem repeat proteins, which are formed by repetition of modular units of protein sequence and structure, play important biological roles as macromolecular binding and scaffolding domains, enzymes, and building blocks for the assembly of fibrous materials. The modular nature of repeat proteins enables the rapid construction and diversification of extended binding surfaces by duplication and recombination of simple building blocks. The overall architecture of tandem repeat protein structures--which is dictated by the internal geometry and local packing of the repeat building blocks--is highly diverse, ranging from extended, super-helical folds that bind peptide, DNA, and RNA partners, to closed and compact conformations with internal cavities suitable for small molecule binding and catalysis. Here we report the development and validation of computational methods for de novo design of tandem repeat protein architectures driven purely by geometric criteria defining the inter-repeat geometry, without reference to the sequences and structures of existing repeat protein families. We have applied these methods to design a series of closed α-solenoid repeat structures (α-toroids) in which the inter-repeat packing geometry is constrained so as to juxtapose the amino (N) and carboxy (C) termini; several of these designed structures have been validated by X-ray crystallography. Unlike previous approaches to tandem repeat protein engineering, our design procedure does not rely on template sequence or structural information taken from natural repeat proteins and hence can produce structures unlike those seen in nature. As an example, we have successfully designed and validated closed α-solenoid repeats with a left-handed helical architecture that--to our knowledge--is not yet present in the protein structure database.

    2011-01-01

    We present an application of interactive global illumination and spatially augmented reality to architectural daylight modeling that allows designers to explore alternative designs and new technologies for improving the sustainability of their buildings. Images of a model in the real world, captured by a camera above the scene, are processed to construct a virtual 3D model. To achieve interactive rendering rates, we use a hybrid rendering technique, leveraging radiosity to simulate the interreflectance between diffuse patches and shadow volumes to generate per-pixel direct illumination. The rendered images are then projected on the real model by four calibrated projectors to help users study the daylighting illumination. The virtual heliodon is a physical design environment in which multiple designers, a designer and a client, or a teacher and students can gather to experience animated visualizations of the natural illumination within a proposed design by controlling the time of day, season, and climate. Furthermore, participants may interactively redesign the geometry and materials of the space by manipulating physical design elements and see the updated lighting simulation. PMID:21071786

A big comfortable habitat can help to overcome sociopsychological problems, that occur in ICEs (Isolated and Confined Environments). Authors have come forward to this issue and have developed a Martian base design as a human friendly habitat. The project is based on researches of extreme conditions on Mars, architecture in ICEs and contemporary building technologies. The base consists of five modules: a Central Module (CM), an Agriculture Dome (AD), a Residential Dome (RD), a Laboratory Dome (LD) and a Garage (G). Each element has its own functional purpose. The CM is a metal capsule similar to the Reference Mission module (RM, NASA, 1997). Domes are inflatable multilayer structures, which interiors are "open planned". Interiors can be arranged and divided into rooms by using modular partition walls designed by authors.

  3. Status of ASTRID architecture and pre-conceptual design

    International Nuclear Information System (INIS)

    In the frame of the June 2006 French act on sustainable management of radioactive materials and wastes, the ASTRID (Advanced Sodium Technological Reactor for Industrial Demonstration) reactor aims to demonstrate, from the 2020’s, at the industrial scale, improvements in the identified fields of progress of Sodium-cooled Fast Reactor (safety, operability, economy) and to perform transmutation demonstration. CEA (French Commission for Atomic Energy and Alternative Energy) is the leader of the ASTRID project, including ten industrial partnerships and EDF SEPTEN for architectural engineering design support. This document presents the status of the ASTRID pre-conceptual and global industrial design. All of the options of processing systems studied by the industrial engineering partners are managed in configuration models, and monitored by a CEA ASTRID project management team. Items addressed in this document include views of nuclear island buildings, other operational and process buildings, projected site layout with requirements and specific constraints (external hazards like earthquake, floods, airplanes crashes…).

    The paper presents a series of thoughts on what architecture is all about in the form of a letter from a ''grandpa'' architect to young architects. The letter touches the subjects of architecture, sustainability and energy efficient design, learning from tradition, the relation of architecture to the other arts, the use of technology and mechanical installations, the holistic approach to design, the elements of which architecture is composed, the constraints in architectural design, the notion of ''less is beautiful'' and many more, giving in this way some food for thought for the younger generations.

  8. Design of an open architecture seismic monitoring system

    International Nuclear Information System (INIS)

    This document presents a top level design of an Open Architecture Seismic Monitoring (OASM) system. The main components of the system are the time series processing, the event formation, the event classification and the hazard assessment modules. These fully independent modules are complemented by operational and research databases. Signal detection, onset time estimation and signal characterization are functions of the time series module. The detected signal association and event location are performed in the event formation module. The characterization of the seismic source, whether natural or artificial, is decided in the event classification module. The seismic hazard assessment module is the part of the system, where the basic parameters for use in seismic risk analysis are estimated. The operational database acts as the central facility through which access to the seismic data and communication between the system's modules are accomplished. The function of the research database is to provide scientists with a seismic bulletin and segmented waveforms for events through local and remote access via computer networks and dial-up telephone circuits. Although, the OASM system is designed to meet specific goals and objectives, its architecture is by no means limited to its current functionality. The first section of this report provides an overview and description of the components and data flow through the system. The second section presents the computational seismological techniques that form the foundation of the system. Only those techniques that are either essential to the design of the system or considered as uncommon signal processing tools are presented in this report. 67 refs

  11. Design Patterns For Successful Service Oriented Architecture Implementation

    Directory of Open Access Journals (Sweden)

    G. M. Tere

    2010-01-01

    Full Text Available The successful implementation of Service Oriented Architecture (SOA relies on a careful and holistic approach to business planning. One of the most important tools in the evaluation, purchase, and ongoing use of SOA is the best practices that vendors, consultants, and customers have developed and used. The promise of business agility, improved customer service, and competitive advantage with SOA is real. What varies most is the time, cost, and ease of SOA implementation. By learning from the experiences of those organizations that have been through the process and looking at the standard best practices of large-scale technology implementations, success can come at earlier stage. The Patterns for e-business are a group of proven, reusable assets that can be used to increase the speed of developing and deploying Web applications. This paper focuses how the Self-Service and Extended Enterprise business patterns, and the Application Integration pattern, can be used to start implementing solutions using the service-oriented architecture approach. Although the model of Web service interoperability is straightforward, it introduces new development practices and methodologies that can be difficult to learn. However, it can be successfully implemented if we recognize certain patterns to design issues.

    The norm CNEN-NE-1.04 'Licensing of Nuclear Facilities' establishes that an applicant of a Construction License of a nuclear power plant should present, among other information, the design bases and the demonstration that these design bases are in accordance with the Principal Design Criteria, as described in the Preliminary Report of Safety Analysis (PSAR). The definition of Principal Design Criteria is related to design requirements for the manufacturing, construction, test and performance of structures, systems and components that are important for the safety. These requirements will guarantee that the plant can operate without undue risk to the workers, public and environment. On the other hand, General Design Criteria establish the minimum requirements, with the same objective of the Principal Design Criteria, applicable to a specific plant type, for instance, a Pressurized Water Reactor (PWR). In this article, the authors discuss the Brazilian experience of licensing in which three groups of General Design Criteria from different origins were used: the North American (US NRC), the German (BMI) and the international (IAEA).

  14. Design and Optimization Approaches in Double Gate Device Architecture

    Directory of Open Access Journals (Sweden)

    K.E.Kaharudin

    2014-10-01

    Full Text Available According to Moore’s law, the number of transistor embedded on integrated circuit (IC doubles approximately every two years. Thus, the size of Metal-Oxide-Semiconductor Field Effect Transistor (MOSFET has to be scaled down as an increase in packing density. In current technology, the size of a transistor has shrunk below 45nm, and it has already reached its physical limit. Any attempt to shrink the MOSFET beyond this limit will expose MOSFET device to various short channel effects (SCEs problems. Recently, however, a new architecture of MOSFET known as Double Gate MOSFET has emerged, and this will allow the IC technology continue to be shrunk while sustaining its electrical performance. Several types of Double gate MOSFET are discussed but however, the main focus is to the type of vertical DG-MOSFET. This paper will discuss about the design and optimization approaches in Double-gate (DG MOSFET device.

  15. Architecture and Design of Medical Processor Units for Medical Networks

    CERN Document Server

    Ahamed, Syed V; 10.5121/ijcnc.2010.2602

    2011-01-01

    This paper introduces analogical and deductive methodologies for the design medical processor units (MPUs). From the study of evolution of numerous earlier processors, we derive the basis for the architecture of MPUs. These specialized processors perform unique medical functions encoded as medical operational codes (mopcs). From a pragmatic perspective, MPUs function very close to CPUs. Both processors have unique operation codes that command the hardware to perform a distinct chain of subprocesses upon operands and generate a specific result unique to the opcode and the operand(s). In medical environments, MPU decodes the mopcs and executes a series of medical sub-processes and sends out secondary commands to the medical machine. Whereas operands in a typical computer system are numerical and logical entities, the operands in medical machine are objects such as such as patients, blood samples, tissues, operating rooms, medical staff, medical bills, patient payments, etc. We follow the functional overlap betw...

  16. On Computational Fluid Dynamics Tools in Architectural Design

    Kirkegaard, Poul Henning; Hougaard, Mads; Stærdahl, Jesper Winther

    In spite of being apparently easy to use, computational fluid dynamics (CFD) based tools require specialist knowledge for modeling as well as for the interpretation of results. This point of view implies also that users of CFD based tools have to be carefully choosing and using them. Especially...... when many existing types of CFD based tools are developed for different purposes but for a user with lack of skills they can seem to be equal and faciliate inappropriate applications. This issue has initiated the present paper where two different types of CFD tools have been explored. A traditional...... engineering computational fluid dynamics (CFD) simulation program ANSYS CFX and a CFD based representative program RealFlow are investigated. These two programs represent two types of CFD based tools available for use during phases of an architectural design process. However, as outlined in two case studies...

  2. Documentation of Software Architecture from a Knowledge Management Perspective - Design Representation

    Science.gov (United States)

    Kruchten, Philippe

    In this chapter we survey how architects have represented architectural knowledge and in particular architectural design. This has evolved over the last 3 decades, from very intuitive and informal, to very structured, abstract and formal, from simple diagrams and metaphors, design notations, and specific languages. As our understanding of architectural knowledge evolved, the importance of design rationale and the decision process became more and more prominent. There is however a constant through this evolution: the systematic use of metaphors.

  3. THE NEW URBAN DESIGN – A SOCIAL THEORY OF ARCHITECTURE ?

    Directory of Open Access Journals (Sweden)

    Alexander R. Cuthbert

    2014-07-01

    Full Text Available Abstract Over the last ten years and 1000 pages of text, I outlined a unified field theory which I refer to as The New Urban Design. Possessing the same structure, the three books can be read in series or in parallel, and may best be described as a matrix of possibilities (Cuthbert 2003, 2006, 2011. In this paper I revisit some of the ideas in these texts that need to be more fully developed. Important among them are the undeniable effects of this new field for architecture and urban planning, and an expanded brief on the use of Marxian modes of production to support social analysis in these disciplines. From this perspective we can at least develop some truth as to the historical progress of urban form. In redefining urban design as an independent field, architecture and urban planning subsequently become different regions of thought from what they had previously entertained, namely during the period when they colonised urban design and shared the spoils between them. Extending this argument even further, it is clear that neither discipline, nor the resulting mainstream urban design (i.e. one produced by architects and planners - have had resort to a social theory of their own existence. All so called theories of architecture and urban planning, have failed with good reason. Architecture has relied almost exclusively on aesthetics and technology for its self awareness. Despite the fact that social theory began to penetrate planning theory in the 1970’s, this did not change the idea that planning can have no internally generated theory other than the trivial, since it is an epiphenomenon of the state. It is not an independent factor in urbanisation, and therefore can have no consciousness of its own that is any more than ideological in the Marxist use of the term. In conclusion, the paper suggests that if the weltanshuung of the New Urban Design is persuasive, this has wide ranging implications for education, practice and the development

    Kyung, Chong-Min

    2011-01-01

    Power consumption becomes the most important design goal in a wide range of electronic systems. There are two driving forces towards this trend: continuing device scaling and ever increasing demand of higher computing power. First, device scaling continues to satisfy Moore’s law via a conventional way of scaling (More Moore) and a new way of exploiting the vertical integration (More than Moore). Second, mobile and IT convergence requires more computing power on the silicon chip than ever. Cell phones are now evolving towards mobile PC. PCs and data centers are becoming commodities in house and a must in industry. Both supply enabled by device scaling and demand triggered by the convergence trend realize more computation on chip (via multi-core, integration of diverse functionalities on mobile SoCs, etc.) and finally more power consumption incurring power-related issues and constraints. Energy-Aware System Design: Algorithms and Architectures provides state-of-the-art ideas for low power design methods from ...

    Full Text Available In this study we present the architecture for use in high-performance switching networks with support quality of service (QoS guarantees. Quality of services guarantees in terms of delay, through-put and loss rate can be provided by using mechanism's support like scheduling and buffer management at switching architecture in packet switching networks. Our architecture is based on a new data structure for the scheduling and memories management which is the circular linked list and the pipeline for the active queues elements. In addition to being very fast, the architecture also scales very well to a large number of priority levels and to large queue size. We give a detailed description of the block that support QoS guarantees. However our proposed architecture is composed of three parts: input controller, backplane and output controller. And we give the corresponding algorithms and the corresponding implementation of this architecture.

    Shape memory polymers (SMPs) are attractive materials due to their unique mechanical properties, including high deformation capacity and shape recovery. SMPs are easier to process, lightweight, and inexpensive compared to their metallic counterparts, shape memory alloys. However, SMPs are limited to relatively small form factors due to their low recovery stresses. Lightweight, micro-architected composite SMPs may overcome these size limitations and offer the ability to combine functional properties (e.g., electrical conductivity) with shape memory behavior. Fabrication of 3D SMP thermoset structures via traditional manufacturing methods is challenging, especially for designs that are composed of multiple materials within porous microarchitectures designed for specific shape change strategies, e.g. sequential shape recovery. We report thermoset SMP composite inks containing some materials from renewable resources that can be 3D printed into complex, multi-material architectures that exhibit programmable shape changes with temperature and time. Through addition of fiber-based fillers, we demonstrate printing of electrically conductive SMPs where multiple shape states may induce functional changes in a device and that shape changes can be actuated via heating of printed composites. The ability of SMPs to recover their original shapes will be advantageous for a broad range of applications, including medical, aerospace, and robotic devices.

    Gampe, F.; Raitt, D.

    2002-01-01

    The word "space" has always been associated with and had a profound impact upon architectural design. Until relatively recently, however, the term has been used in a different sense to that understood by the aerospace community - for them, space was less abstract, more concrete and used in the context of space flight and space exploration, rather than, say, an empty area or space requiring to be filled by furniture. However, the two senses of the word space have now converged to some extent. Interior designers and architects have been involved in designing the interior of Skylab, the structure of the International Space Station, and futuristic space hotels. Today, architects are designing, and builders are building, houses, offices and other structures which incorporate a plethora of new technologies, materials and production processes in an effort not only to introduce innovative and adventurous ideas but also in an attempt to address environmental and social issues. Foremost among these new technologies and materials being considered today are those that have been developed for and by the space industry. This paper examines some of these space technologies, such as energy efficient solar cells, durable plastics, air and water filtration techniques, which have been adapted to both provide power while reducing energy consumption, conserve resources and so on. Several of these technologies have now been employed by the European Space Agency to develop a Space House TM - the first of its kind, which will be deployed not so much on planets like Mars, but rather here on Earth. The Space House TM, which exhibits many innovative features such as high strength light-weight carbon composites, active noise-damped, (glass and plastic) windows, low-cost solar arrays and latent heat storage, air and water purification systems will be described.

    2014-01-01

    Increased public awareness of carbon footprints, crowding in urban areas, and rising housing costs have spawned a 'small house movement' in the housing industry. Members of this movement desire small, yet highly functional residences which are both affordable and sensitive to consumer comfort standards. In order to create comfortable, minimum-volume interiors, recent advances have been made in furniture design and approaches to interior layout that improve both space utilization and encourage multi-functional design for small homes, apartments, naval, and recreational vehicles. Design efforts in this evolving niche of terrestrial architecture can provide useful insights leading to innovation and efficiency in the design of space habitats for future human space exploration missions. This paper highlights many of the cross-cutting architectural solutions used in small space design which are applicable to the spacecraft interior design problem. Specific solutions discussed include reconfigurable, multi-purpose spaces; collapsible or transformable furniture; multi-purpose accommodations; efficient, space saving appliances; stowable and mobile workstations; and the miniaturization of electronics and computing hardware. For each of these design features, descriptions of how they save interior volume or mitigate other small space issues such as confinement stress or crowding are discussed. Finally, recommendations are provided to provide guidance for future designs and identify potential collaborations with the small spaces design community.

  18. Treatment of irradiation effects in structural design criteria for fusion reactors

    International Nuclear Information System (INIS)

    The irradiation environment experienced by the in-vessel components of fusion reactors such as the International Thermonuclear Experimental Reactor (ITER) presents structural design challenges not envisioned in the development of existing structural design criteria such as the ASME Code or RCC-MR. From the standpoint of structural design criteria, the most significant issues stem from the irradiation-induced changes in material properties, specifically the reduction of ductility, strain hardening capability, and fracture toughness with neutron irradiation. These effects call into question the basis of the design rules in existing structural design criteria which assume that only code-approved materials with high toughness, ductility and strain hardening capability will be used. The present paper reviews the basis of new rules that address these issues in Draft 5 of the interim ITER structural design criteria (ISDC) which was released recently for trial use by the ITER designers

  3. Architecture & Design of Affordable and Highly Available Enterprise Cloud Service

    Directory of Open Access Journals (Sweden)

    Rabi Prasad Padhy

    2013-01-01

    Full Text Available Cloud computing is a way to increase capacity or add capabilities on the fly without investing in additional infrastructure, licensing additional software or training new personnel. Enterprises must embrace this bleeding edge real-time business model in order to compete in the current marketplace. Deployment of enterprise applications in public cloud can reduce investment on IT infrastructure both in terms of hardware and software, whenever new services are to be provisioned. Furthermore, cloud services are quite attractive to business because of its dynamic scalability, privacy, performance and ability to handle heterogeneous environments. Instead of spending a lot of time in figuring out server setup and working on routers, it is judicious to subscribe cloud based 24/7 support and affordable services. It’s an extremely important consideration to subscribe to at least two cloud vendors for smooth running of applications and ensure application availability by switching from one provider to another with minimal management effort. In this article we have proposed an architecture and design of a cost affordable online enterprise cloud application that subscribes to two public cloud vendors with respect to cost and availability parameters. We also present the reasons for the current trend of enterprises moving towards 24/7 online business cloud services.

  9. Packaging design criteria modified fuel spacer burial box. Revision 1

    International Nuclear Information System (INIS)

    Various Hanford facilities must transfer large radioactively contaminated items to burial/storage. Presently, there are eighteen Fuel Spacer Burial Boxes (FSBBs) available on the Hanford Site for transport of such items. Previously, the FSBBS were transported from a rail car to the burial trench via a drag-off operation. To allow for the lifting of the boxes into the burial trench, it will be necessary to improve the packagings lifting attachments and provide structural reinforcement. Additional safety improvements to the packaging system will be provided by the addition of a positive closure system and package ventilation. FSBBs that are modified in such a manner are referred to as Modified Fuel Spacer Burial Boxes (MFSBs). The criteria provided by this PDC will be used to demonstrate that the transfer of the MFSB will provide an equivalent degree of safety as would be provided by a package meeting offsite transportation requirements. This fulfills the onsite transportation safety requirements implemented in WHC-CM-2-14, Hazardous Material Packaging and Shipping. A Safety Analysis Report for Packaging (SARP) will be prepared to evaluate the safety of the transfer operation. Approval of the SARP is required to authorize transfer. Criteria are also established to ensure burial requirements are met

  11. Planning, architecture, seismic, construction and energy-related criteria for sustainable spatial development in the Danube Delta Biosphere Reserve area

    Directory of Open Access Journals (Sweden)

    Vasile Meiţă

    2014-09-01

    Full Text Available The Danube Delta Biosphere Reserve represents a complex of ecosystems embedding a biome that had been included on UNESCO World Heritage list due to its global environmental importance. The outstanding natural diversity, including ecosystems, habitats and species situated at the top of European and International conservation lists, is mixed with an equally rich and important cultural (ethnic and religious diversity of the human communities inhabiting the area. According to the guidelines of the Man and the Biosphere Programme of UNESCO, the biosphere reserves including human settlements should be managed such that they could constitute an example for what sustainable development means. Starting from the spatial dimension added to the traditional socioeconomic, ecological and cultural pillars of sustainable development, the paper examines planning, architecture, seismic, construction and energy-related criteria that could substantiate a sustainable development model applicable to the Danube Delta, and counter the effects of clime change in the area. The results suggest that the traditional practices of the inhabitants could offer sustainable solutions and help preserving the natural and cultural diversity of the region.

  12. Architectural design proposal for a Martian base to continue NASA Mars Design Reference Mission

    Science.gov (United States)

    Kozicki, Janek

    The issue of extraterrestrial bases has recently been a very vivid one. There are orbital stations currently existing and humans will travel to Mars around 2030. They will need stations established there, which will provide them the proper living conditions. Firstly, it might be a small module brought from Earth (e.g. NASA Mars Design Reference Mission module (DRM)), in later stages equivalents of Earth houses may be built from local resources. The goal of this paper is to propose an architectural design for an intermediate stage — for a larger habitable unit transported from Earth. It is inspired by terrestrial portable architecture ideas. A pneumatic structure requires small volume during transportation. However, it provides large habitable space after deployment. It is designed for transport by DRM transportation module and its deployment is considerable easy and brief. An architectural solution analogous to a terrestrial house with a studio and a workshop was assumed. Its form was a result of technical and environmental limitations, and the need for an ergonomic interior. The spatial placement of following zones was carefully considered: residential, agricultural and science, as well as a garage with a workshop, transportation routes, and a control and communication center. The issues of Life Support System, energy, food, water and waste recycling were also discussed. This Martian base was designed to be crewed by a team of eight people to stay on Mars for at least 1.5 year. An Open Plan architectural solution was assumed in pneumatic modules, with a high level of modularity. Walls of standardized sizes with zip-fasteners allow free rearrangement of the interior to adapt to a new situation (e.g. damage of one of the pneumatic modules or a psychological ,,need of a change"). The architectural design focuses on ergonomic and psychological aspects of longer stay in hostile Martian environment. This solution provides Martian crew with a comfortable habitable

  13. Thermal-hydraulic criteria for the APT tungsten neutron source design

    International Nuclear Information System (INIS)

    This report presents the thermal-hydraulic design criteria (THDC) developed for the tungsten neutron source (TNS). The THDC are developed for the normal operations, operational transients, and design-basis accidents. The requirements of the safety analyses are incorporated into the design criteria, consistent with the integrated safety management and the safety-by-design philosophy implemented throughout the APT design process. The phenomenology limiting the thermal-hydraulic design and the confidence level requirements for each limit are discussed. The overall philosophy of the uncertainty analyses and the confidence level requirements also are presented. Different sets of criteria are developed for normal operations, operational transients, anticipated accidents, unlikely accidents, extremely unlikely accidents, and accidents during TNS replacement. In general, the philosophy is to use the strictest criteria for the high-frequency events. The criteria is relaxed as the event frequencies become smaller. The THDC must be considered as a guide for the design philosophy and not as a hard limit. When achievable, design margins greater than those required by the THDC must be used. However, if a specific event sequence cannot meet the THDC, expensive design changes are not necessary if the single event sequence results in sufficient margin to safety criteria and does not challenge the plant availability or investment protection considerations

    Chinnachodteeranun, R.; Hung, N. D.; Honda, K.

    2015-12-01

    Crop simulation models are efficient tools for simulating crop growth processes and yield. Running crop models requires data from various sources as well as time-consuming data processing, such as data quality checking and data formatting, before those data can be inputted to the model. It makes the use of crop modeling limited only to crop modelers. We aim to make running crop models convenient for various users so that the utilization of crop models will be expanded, which will directly improve agricultural applications. As the first step, we had developed a prototype that runs DSSAT on Web called as Tomorrow's Rice (v. 1). It predicts rice yields based on a planting date, rice's variety and soil characteristics using DSSAT crop model. A user only needs to select a planting location on the Web GUI then the system queried historical weather data from available sources and expected yield is returned. Currently, we are working on weather data connection via Sensor Observation Service (SOS) interface defined by Open Geospatial Consortium (OGC). Weather data can be automatically connected to a weather generator for generating weather scenarios for running the crop model. In order to expand these services further, we are designing a web service framework consisting of layers of web services to support compositions and executions for running crop simulations. This framework allows a third party application to call and cascade each service as it needs for data preparation and running DSSAT model using a dynamic web service mechanism. The framework has a module to manage data format conversion, which means users do not need to spend their time curating the data inputs. Dynamic linking of data sources and services are implemented using the Service Component Architecture (SCA). This agriculture web service platform demonstrates interoperability of weather data using SOS interface, convenient connections between weather data sources and weather generator, and connecting

  15. Reliability evaluation of axially loaded steel members design criteria in AASHTO LRFD bridge design code

    International Nuclear Information System (INIS)

    Reliability based structural design insures a uniformly designed structure, in terms of safety. By considering an adequate reliability index (or probability of failure) for different parts of a structure, a reasonable balance between cost and safety of the structure can be achieved. In this study, the reliability of steel tension and compression members designed with AASHTO LRFD bridge design specifications (2007) is evaluated. These members are prevalent in different types of truss or arch bridges. Various conditions such as redundancy, ductility and importance of the bridge are taken into account by changing the load modification factor, η. To include the effect of the span length, a variable ratio of dead load to total load is considered. Current load factors in AASHTO LRFD code are accepted due to their verification in a comprehensive study for reliability of girder-type bridges. Furthermore, load and resistance distribution models are chosen based on the latest existing experimental data. The Monte Carlo simulation technique with randomly generated samples is applied in numerical calculations. For tension members, analysis results show relatively high reliability indices in yielding design, while having slightly low reliabilities for the fracture mode. For fracture design of steel tension members, an increase in vehicular dynamic load allowance (IM) from 33% to 75% is suggested to insure a safer behavior. Also, it is shown that the resistance factor for yielding of gross section, φy, can be increased from 0.95 to 1.00 while maintaining enough safety for designed tension members. In addition, obtained reliability curves for steel compression members show a safe behavior of designed compression members with conservative response in some cases. More results and plotted curves are discussed in detail and possible adjustments in code criteria are presented in this paper

    RNA interference can be used as a tool for gene silencing mediated by small interfering RNAs (siRNA). The critical step in effective and specific RNAi processing is the selection of suitable constructs. Major design criteria, i.e., Reynolds's design rules, thermodynamic stability, internal repeats, immunostimulatory motifs were emphasized and implemented in the siRNA design tool. The tool provides thermodynamic stability score, GC content and a total score based on other design criteria in the output. The viability of the tool was established with different datasets. In general, the siRNA constructs produced by the tool had better thermodynamic score and positional properties. Comparable thermodynamic scores and better total scores were observed with the existing tools. Moreover, the results generated had comparable off-target silencing effect. Criteria evaluations with additional criteria were achieved in WEKA. PMID:21145307

  1. Contents specification criteria for package design approvals in Germany

    International Nuclear Information System (INIS)

    Requirements for a package design for the transport of radioactive and fissile material are established in the Regulations for the Safe Transport of Radioactive Material - 1996 Edition (TS-R-1). Beginning with the first edition in 1961 the Regulations for the Safe Transport of Radioactive Material were developed consequently to a high standard to protect persons, property and the environment from the effects of radiation during the transport of radioactive material by placing the primary reliance on the package design. One important part of the package design approval procedure is to show that all dose rate limits and other requirements relating to radiation shielding are fulfilled when the maximum radioactive contents is considered. The applicant has to find covering parameters for the contents description which will be fixed in the package design approval certificate as maximum permissible parameters. This paper describes the contents description for spent fuel elements and vitrified high level radioactive waste (HAW) from the reprocessing which are acceptable to the Federal Office for Radiation Protection (BfS) as the competent authority for package design approval. Such parameters for spent fuel elements are i.e. enrichment, burn-up, cooling time, or the description by source strengths for gamma and neutron emitters. It is also shown which specific evidences, i.e. for weak areas of the shielding, are requested by BfS. (author)

    Target performance can be achieved by defining design basis ground motion from results of a probabilistic seismic hazards assessment, and introducing known levels of conservatism in the design above the DBE. ASCE 4, 43, DOE-STD-1020 defined the DBE at 4x10-4 and introduce only slight levels of conservatism in response. ASCE 4, 43, DOE-STD-1020 assume code capacities shoot for about 98% NEP. There is a need to have a uniform target (98% NEP) for code developers (ACI, AISC, etc.) to aim for. In considering strengthening options, one must also consider cost/risk reduction achieved.

  10. Conceptual Design on the System Architecture of Intellectual Export Control System(IXCS)

    International Nuclear Information System (INIS)

    The commodity classification is for identifying strategic commodity, and the export license is for verifying that exports have met the requirement by the national legislation following international obligations (i. e. NSG guidelines) Since 2008, the 'Nuclear Export Promotion Service (NEPS)' System has been used as a total IT system providing various functions for exporters and reviewers. However, reviewers who make the decisions for commodity classification and export license, may have difficulties caused by ambiguity of criteria. For example, it is not sure whether a CVCS (Chemical Volume Control System) of a certain nuclear reactor plant belongs to strategic commodity or not. The NEPS is a useful system helping users save their time, but it cannot provide solutions reducing ambiguity of each classification or license case. To solve these problems and provide more efficient ways to their decisions, various intelligent IT solutions are searched and studied. A functional architecture of IXCS is defined and designed conceptually. This conceptual design will be utilized to make database specification and to find the optimized artificial algorithm for review processes

  12. Nuclear renaissance, public perception and design criteria: An exploratory review

    International Nuclear Information System (INIS)

    There is currently an international drive to build new nuclear power plants, bringing about what is being termed a 'nuclear renaissance'. However, the public perception of nuclear energy has historically been, and continues to be, a key issue, particularly in light of the Fukushima nuclear incident. This paper discusses the disparity between perceived and calculated risks based on the last four decades of research into risk perception. The leading psychological and sociological theories, Psychometric Paradigm and Cultural Theory, respectively, are critically reviewed. The authors then argue that a new nuclear-build policy that promotes a broader approach to design incorporating a wider range of stakeholder inputs, including that of the lay public, may provide a means for reducing the perceived risk of a nuclear plant. Further research towards such a new approach to design is proposed, based on integrating expert and lay stakeholder inputs and taking into account broader socio-cultural factors whilst maintaining the necessary emphasis on safety, technological development, economics and environmental sustainability. - Highlights: → Globally, a number of countries are investing in or considering building new nuclear plants. → Public acceptance of nuclear safety is important to continuing new nuclear build efforts. → Theories are discussed attempting to explain the public perception of nuclear safety. → A socially informed design process is proposed which could assist in ensuring public support. → Further research to understand how this design process might be performed is proposed.

  20. Natural phenomena hazards design and evaluation criteria for Department of Energy Facilities

    Energy Technology Data Exchange (ETDEWEB)

    NONE

    1996-01-01

    The Department of Energy (DOE) has issued an Order 420.1 which establishes policy for its facilities in the event of natural phenomena hazards (NPH) along with associated NPH mitigation requirements. This DOE Standard gives design and evaluation criteria for NPH effects as guidance for implementing the NPH mitigation requirements of DOE Order 420.1 and the associated implementation Guides. These are intended to be consistent design and evaluation criteria for protection against natural phenomena hazards at DOE sites throughout the United States. The goal of these criteria is to assure that DOE facilities can withstand the effects of natural phenomena such as earthquakes, extreme winds, tornadoes, and flooding. These criteria apply to the design of new facilities and the evaluation of existing facilities. They may also be used for modification and upgrading of existing facilities as appropriate. The design and evaluation criteria presented herein control the level of conservatism introduced in the design/evaluation process such that earthquake, wind, and flood hazards are treated on a consistent basis. These criteria also employ a graded approach to ensure that the level of conservatism and rigor in design/evaluation is appropriate for facility characteristics such as importance, hazards to people on and off site, and threat to the environment. For each natural phenomena hazard covered, these criteria consist of the following: Performance Categories and target performance goals as specified in the DOE Order 420.1 NPH Implementation Guide, and DOE-STD-1 021; specified probability levels from which natural phenomena hazard loading on structures, equipment, and systems is developed; and design and evaluation procedures to evaluate response to NPH loads and criteria to assess whether or not computed response is permissible.

  1. Considerations for developing seismic design criteria for nuclear waste storage repositories

    International Nuclear Information System (INIS)

    The function of seismic design criteria is to reduce the potential for hazards that may arise during various stages of the repository life. During the operational phase, the major concern is with the possible effects of earthquakes on surface facilities, underground facilities, and equipment. During the decommissioned phase, the major concern is with the potential effects of earthquakes on the geologic formation, which may result in a reduction in isolation capacity. Existing standards and guides or criteria used for the static and seismic design of licensed nuclear facilities were reviewed and evaluated for their applicability to repository design. This report is directed mainly toward the development of seismic design criteria for the underground structures of repositories. An initial step in the development of seismic design criteria for the underground structures of repositories is the development of performance criteria, or minimum standards of acceptable behavior. A number of possible damage modes are identified for the operating phase of the repository; however, no damage modes are foreseen that would perturb the long-term function of the repository, except for the possibility of increased permeability within the rock mass. Subsequent steps in formulating acceptable seismic design criteria for the underground structures involve the quantification of the design process. The report discusses the necessity of specifying the form of ground motion that would be needed for seismic analysis and the procedures that may be used for making ground motion predictions. Further discussions outline what is needed for analysis, including rock properties, failure criteria, modeling techniques, seismic hardening criteria for the host rock mass, and probabilistic considerations

    Full Text Available The design studio is the core of the architecture curriculum. Interpersonal interactions have a key role during the processes of design and critique. The influence of emotional intelligence (EQ on interpersonal communication skills has been widely proven. This study examines the correlation between EQ and architectural design competence. To achieve this, 78 architecture students were selected via a simple random sampling method and tested using an EQ test questionnaire developed by Bradbury and Greaves (2006. The scores of five architectural design studio courses (ADS-1, ADS-2, ADS-3, ADS-4, and ADS-5 were used as indicators of the progress in design of the students. Descriptive and inferential statistics methods were both employed to analyze the research data. The methods included correlation analysis, mean comparison t-test for independent samples, and single sample t-test. Findings showed no significant relationship between EQ and any of the indicators.

  3. Web Services Security Architectures Composition and Contract Design using RBAC

    Directory of Open Access Journals (Sweden)

    2010-11-01

    Full Text Available Service Oriented Architecture’s Web Services authorization traditionally is done using common access control models like Role-Based Access Control. In thinking of a composite application that stitches together the capabilities of multiple services, any action in the composite app should ideally check the access control rules of all constituent services before initiating an action. The WebServices Access controls are categorized according to access control granularity and have two approaches: The first approach supports a negotiation-based attribute-based access control to Web Services with fine access granularity. The second approach is tailored to access control for conversation-based Web services and composite services;where in a Web Service is not considered as a set of independent operations and therefore access control must take such dependencies into account. During a Web Services invocation, a client interacts with the service, performing a sequence of operations in a particular order called conversation. In this paper, we want to propose strategies for analyzing and managing Role Based Access Control policies for designing Security Architectures for web services. Wevalidate role-based access control with a case study, where in access decisions are based on the roles that individual users have as part of an organization. Users take on assigned roles. The process of defining roles should be based on a thorough analysis of how an organization operates and should include input from a wide spectrum of users in an organization. Access rights are grouped by role name, and the use of resources is restricted to individuals authorized toassume the associated role. For example, within a hospital system the role of doctor can include operations to perform diagnosis, prescribe medication, and order laboratory tests; and the role of researcher can be limited to gathering anonymous clinical information for studies.

  5. System Framework for the Design of an Avionics Architecture with Upgrade Potential

    Directory of Open Access Journals (Sweden)

    N. Rao

    2002-01-01

    Full Text Available The technological growth of ‘avionics systems’ has outpaced the service-life of aircraft, resulting in avionics upgrade as a preferred cost-effective option to new design. Mid-life upgrade of “avionics systems“ by state-of-the-art mission systems has been a challenging engineering task. The complexity of avionics upgrade process is due to the design rigidity of avionics systems architecture. An avionics architecture with growth potential is required to optimise avionics upgrade with state-of-the-art systems. A research program that partially addresses avionics systems upgrade by developing a methodology to design an avionics architecture with in-built growth potential is discussed in this research paper. A ‘system approach’ is adopted to develop a methodology that identifies the design parameters that will facilitate design of an avionics architecture with upgrade potential.

  6. Design criteria and concepts for vented containment systems

    International Nuclear Information System (INIS)

    Accident sequences from WASH-1400 were selected and analyzed with the MARCH/CORRAL code to provide an envelope of design conditions. The time-dependent pressures and temperatures in containment were calculated as were the concentrations of steam, noncondensible gases, and airborne fission products in the containment atmosphere. The phenomenon found to be most challenging to containment integrity was a pressure spike resulting from rapid steam generation and/or hydrogen burning. The peak pressures in some sequences exceed the likely failure pressure. Conceptual designs were developed for preserving containment integrity. These include containment pressure relief or depressurization with various venting rates. Anticipatory venting, venting to the atmosphere, venting to a separate building, and venting followed by recirculation back into containment are considered. The effects of these schemes on the important system parameters were identified. The advantages and disadvantages of alternative schemes and their implications for the design of filtration equipment are discussed. For each venting strategy several levels of filtering effectiveness were considered. The simplest option developed is a once-through gravel-filled suppression pool. More sophisticated options involved sand filters, molecular sieves, charcoal adsorbers and HEPA filters. Results of accident consequence calculations using the CRAC code indicate the relatively simple options can provide substantial reductions in consequences of certain accident sequences. 12 figures

  9. Design of a polymer thermoelectric generator using radial architecture

    Science.gov (United States)

    Menon, Akanksha K.; Yee, Shannon K.

    2016-02-01

    Thermoelectric generators (TEGs) are solid-state heat engines consisting of p-type and n-type semiconductors that convert heat into electricity via the Seebeck effect. Conducting polymers are a viable alternative with intrinsic advantages over their inorganic counterparts, since they are abundant, flexible as thick-films, and have reduced manufacturing costs due to solution processing. Furthermore, polymers have an inherently low thermal conductivity, thus affording them the option of forgoing some heat exchanger costs. Current examples of polymer TE devices have been limited to traditional flat-plate geometries with power densities on the μW/cm2 scale, where their potential is not fully realized. Herein, we report a novel radial device architecture and model the improved performance of polymer-based TEG based on this architecture. Our radial architecture accommodates a fluid as the heat source and can operate under natural convection alone due to heat spreading. Analytical heat transfer and electrical models are presented that optimize the device for maximum power density, and for the first time we obtain the geometry matching condition that maximizes the efficiency. We predict high power densities of ˜1 mW/cm2 using state-of-the-art polymer TEs subjected to a temperature difference of 100 K, which is nearly 1000× higher than polymer flat-plate architectures reported in literature.

  10. Seismic design and evaluation criteria for DOE facilities (DOE-STD-1020-XX)

    International Nuclear Information System (INIS)

    Seismic design and evaluation criteria for DOE facilities are provided in DOE-STD-1020-XX. The criteria include selection of design/evaluation seismic input from probabilistic seismic hazard curves combined with commonly practiced deterministic response evaluation methods and acceptance criteria with controlled levels of conservatism. Conservatism is intentionally introduced in specification of material strengths and capacities, in the allowance of limited inelastic behavior and by a seismic load factor. These criteria are based on the performance or risk goals specified in DOE 5480.28. Criteria have been developed following a graded approach for several performance goals ranging from that appropriate for normal-use facilities to that appropriate for facilities involving hazardous or critical operations. Performance goals are comprised of desired behavior and of the probability of not achieving that behavior. Following the seismic design/evaluation criteria of DOE-STD-1020-XX is sufficient to demonstrate that the probabilistic performance or risk goals are achieved. The criteria are simple procedures but with a sound, rigorous basis for the achievement of goals

    2008-07-01

    The main objective of this research was to develop practical tools with which it is possible to improve the environment, micro-climate and energy economy of buildings and plans in different climate zones, and take the climate change into account. The parts of the study are: State of art study into existing know-how about climate and planning. Study of the effects of climate change on the built environment. Development of simple micro-climate, nature and built environment analysis methods. Defining the criteria of an acceptable micro-climatic environment. Development of the wind test blower. Presenting ways to interpret test results and draw conclusions. Development of planning and design guidelines for different climate zones. An important part of the research is the development of the CASE wind test instrument, different wind simulation techniques, and the methods of observing the results. Bioclimatic planning and architectural design guidelines for different climate zones are produced. The analyse tools developed give a qualitative overall view, which can be deepened towards a quantitative analyse with wind testing measurements and roughness calculations. No mechanical rules are suggested, but complementary viewpoints and practices introduced to a normal planning process as well as improvement of consultative knowledge. The 'method' is that there is no strict mechanical method, but a deeper understanding of bioclimatic matters. Climate-conscious planning with the developed CASE method, make it possible to design a better micro-climate for new or old built-up areas. Winds can be used in to ventilate exhaust fumes and other pollutants, which improves the quality of air and the healthiness of the urban environment. The analyses and scale-model tests make it possible to shield cold windy areas and to diminish the cooling effect of wind on facades. According to studies in Scandinavian countries this will bring energy savings of 5-15 per cent. The method can

    Pedersen, Christian; Lichtenberg Hansen, P.; Buchhave, Preben; Skettrup, Torben

    We present a comprehensive Jones matrix analysis of two commonly used ring laser resonators. Different aspects on how to obtain low loss eigenmodes and/or high loss difference between the two directions of the cavity, and thus high frequency stability, are investigated. Also different...... approximations are evaluated. Since the theory has been kept general, the derived results can be applied to a large class of ring laser designs. Finally the influence of backscattered light on the stability is considered. Experimental results on two ring lasers are discussed....

  13. Impact of structural design criteria on first wall surface heat flux limit

    Energy Technology Data Exchange (ETDEWEB)

    1998-09-01

    The irradiation environment experienced by the in-vessel components of fusion reactors presents structural design challenges not envisioned in the development of existing structural design criteria such as the ASME Code or RCC-MR. From the standpoint of design criteria, the most significant issues stem from the irradiation-induced changes in material properties, specifically the reduction of ductility, strain hardening capability, and fracture toughness with neutron irradiation. Recently, Draft 7 of the ITER structural design criteria (ISDC), which provide new rules for guarding against such problems, was released for trial use by the ITER designers. The new rules, which were derived from a simple model based on the concept of elastic follow up factor, provide primary and secondary stress limits as functions of uniform elongation and ductility. The implication of these rules on the allowable surface heat flux on typical first walls made of type 316 stainless steel and vanadium alloys are discussed.

  15. Design Criteria for Suspended Pipelines Based on Structural Analysis

    Directory of Open Access Journals (Sweden)

    2016-06-01

    Full Text Available Mathematical models have become the target of numerous attempts to obtain results that can be extrapolated to the study of hydraulic pressure infrastructures associated with different engineering requests. Simulation analysis based on finite element method (FEM models are used to determine the vulnerability of hydraulic systems under different types of actions (e.g., natural events and pressure variation. As part of the numerical simulation of a suspended pipeline, the adequacy of existing supports to sustain the pressure loads is verified. With a certain value of load application, the pipeline is forced to sway sideways, possibly lifting up off its deadweight supports. Thus, identifying the frequency, consequences and predictability of accidental events is of extreme importance. This study focuses on the stability of vertical supports associated with extreme transient loads and how a pipeline design can be improved using FEM simulations, in the design stage, to avoid accidents. Distribution of bending moments, axial forces, displacements and deformations along the pipeline and supports are studied for a set of important parametric variations. A good representation of the pipeline displacements is obtained using FEM.

  17. Design criteria for pultruded fiber-reinforced polymer composite columns

    Science.gov (United States)

    Choi, Yeol

    This dissertation investigated the behavior of pultruded fiber-reinforced polymer (FRP) composite columns under extensive time-independent short-term and time-dependent long-term experiments. Based on the experimental results, analytical studies were performed to propose a design approach for pultruded FRP composite columns. In the time-independent short-term tests, a total of 100 tests on wide flange, I-shape and box section columns were selected to develop the empirical column strength equation. All column tests were performed with pinned-pinned end conditions using either a 30 feet reaction frame or a MTS machine depending on the column length. The experimental results from short-term column tests provided valuable realistic information, such as the ultimate column capacity, failure mode, and column strength equation for pultruded FRP composite columns subjected to axial compression. To develop empirical column strength equation, ultimate column capacity at failure may be examined by plotting of the ultimate compressive stress versus effective slenderness ratio, and then nondimensionalize the ultimate compressive stress and slenderness ratio to compare columns having different cross sections. Finally, a set of empirical column strength equations of FRP composite column was developed from the column strength curves using curve-fitting technique. In the time-dependent long-term creep tests, a total of 4 box and 4 wide flange section columns were tested to investigate time-dependent deformation of pultruded FRP composite columns. The cross-section used in the investigation is 4 in. x 4 in. x 1/4 in. (100 mm x 100 mm x 6.4 mm) and length is 4 feet (1.2 m) with box and wide flange sections. Creep tests were carried out at four different loading levels; 20, 30, 40 and 50 percents of the ultimate column strength from the short-term column tests. The axial time-dependent deformation under sustained loading was monitored for time duration up to 2,500 hours. The

    2016-04-01

    Full Text Available Data-Context-Interactions architecture (DCI is a software paradigm whose main goal is to bring the end user's mental models and computer program models closer together. It has been shown, however, that developing applications according to the DCI principles is rather difficult in the current languages. This paper presents a novel way of developing applications according to DCI in the framework of Morpheus, which is a proof-of-concept implementation of Object Morphology (OM in Scala. OM is a new object-oriented paradigm developed to model highly mutable phenomena that may mutate not only with regard to state, but also with regard to type. Instead of classes, OM uses the concept of morph models describing possible forms of objects. Using a simple example it is demonstrated how natural and straightforward it could be to implement applications following the DCI architectural tenets.

  13. Guidelines and criteria for nuclear piping and support evaluation and design

    International Nuclear Information System (INIS)

    The EPRI Research Project 2967-2 has set its fundamental goal to be the development of realistic guidelines and criteria for piping and pipe support design and evaluation. The focus is on items that are most critical to utilities and consists of a variety of tasks relating to piping and pipe support design. One objective of this report is to summarize the recommendations from the seven task reports of the first phase of the project and to provide examples of how to use those recommendations. Criteria and methods for evaluating both short and long term system operation are addressed. Benefits gained from applying the recommendations to actual systems are discussed. The report also reviews other work currently being done within the nuclear industry and assesses the impact of that work on the recommended criteria/methods of this project. The second objective of the report is to discuss possible changes needed in the governing codes or licensing commitments in order to implement the recommendations. Finally, the report describes further research which can be done to advance the criteria presented and answer questions concerning applicability of the proposed criteria to designs not tested/investigated. The basic conclusion reached in the project is that many of the criteria/methods used today in piping analysis/design are overly conservative. The report's conclusion is supported by extensive literature searches, tests, and analyses. The report presents a robust source of reference to utilities which wish to implement changes in criteria and methods. Most of the criteria and methodologies described in the seven task reports and summarized in the following sections will require some effort in licensing or Code changes

    Research into complexities of software systems Fault Management (FM) and how architectural design decisions affect safety, preservation of assets, and maintenance of desired system functionality has coalesced into a technical reference (TR) suite that advances the provision of safety and mission assurance. The NASA Independent Verification and Validation (IV&V) Program, with Software Assurance Research Program support, extracted FM architectures across the IV&V portfolio to evaluate robustness, assess visibility for validation and test, and define software assurance methods applied to the architectures and designs. This investigation spanned IV&V projects with seven different primary developers, a wide range of sizes and complexities, and encompassed Deep Space Robotic, Human Spaceflight, and Earth Orbiter mission FM architectures. The initiative continues with an expansion of the TR suite to include Launch Vehicles, adding the benefit of investigating differences intrinsic to model-based FM architectures and insight into complexities of FM within an Agile software development environment, in order to improve awareness of how nontraditional processes affect FM architectural design and system health management. The identification of particular FM architectures, visibility, and associated IV&V techniques provides a TR suite that enables greater assurance that critical software systems will adequately protect against faults and respond to adverse conditions. Additionally, the role FM has with regard to strengthened security requirements, with potential to advance overall asset protection of flight software systems, is being addressed with the development of an adverse conditions database encompassing flight software vulnerabilities. Capitalizing on the established framework, this TR suite provides assurance capability for a variety of FM architectures and varied development approaches. Research results are being disseminated across NASA, other agencies, and the

    The layered control architecture is designed for the need of the multirobot intelligent team formation.There are three levels:the cooperation task level, the coordination behavior level and the action planning level.The cooperation task level uses the potential grid method, which improves the safety of the path and reduces the calculation complexity. The coordination behavior level uses the reinforcement learning which can strengthen the robots' intelligence. The action planning level uses the fuzzy planning methods to realize the action matching.The communication model transfers the message in different level. This architecture shows not only the independence and the intelligence of the single robot but also the cooperation and the coordination among the robots.In each level, the task is distributed reasonably and clearly. Finally the feasibility of the architecture is verified further in the simulation of the experiment. The expansibility of the architecture is good and the architecture can be used in the similar system.

    Full Text Available Smart devices and cyber-physical systems, which are interconnected to IT systems and services, form the basis for the arising Internet of Everything, opening up new economic opportunities for its participants and users beyond its technological aspects and challenges. While today’s e-business scenarios are mostly dominated by a few centralized online platforms, future business models, which will be feasible for the Internet of Everything, need to address special requirements. Such business models, e.g., leveraging the possibilities of smart cities, need to cope with arbitrary combinations of products and services orchestrated into complex products in a highly distributed and dynamic environment. Furthermore, these arbitrary combinations are influenced by real-time context information derived from sensor networks or IT systems, as well as the users’ requirements and preferences. The complexity of finding the optimal product/service combination overstrains users and leads to decisions according to the principle of adverse selection (i.e., choosing good enough instead of optimal. Such e-business models require an appropriate underlying value generation architecture that supports users in this process. In this paper, we develop a business model that addresses these problems. In addition, we present the Distributed Market Spaces (DMS software-system architecture as a possible implementation, which enables the aforementioned decentralized and context-centric e-business scenario and leverages the commercial possibilities of smart cities.

    2007-01-01

    Network processors are used in the core node of network to flexibly process packet streams. With the increase of performance, the power of network processor increases fast, and power and cooling become a bottleneck. Architecture-level power conscious design must go beyond low-level circuit design. Architectural power and performance tradeoff should be considered at the same time. Simulation is an efficient method to design modern network processor before making chip. In order to achieve the tradeoff between performance and power,the processor simulator is used to design the architecture of network processor. Using Netbench, Commubench benchmark and processor simulator-SimpleScalar, the performance and power of network processor are quantitatively evaluated. New performance tradeoff evaluation metric is proposed to analyze the architecture of network processor. Based on the high performance Intel IXP 2800 Network processor configuration, optimized instruction fetch width and speed 、instruction issue width, instruction window size are analyzed and selected. Simulation results show that the tradeoff design method makes the usage of network processor more effectively. The optimal key parameters of network processor are important in architecture-level design. It is meaningful for the next generation network processor design.

  11. Integration of system design and production processes in robust mechatronic product architectures development - extended M-FBFP framework

    Full Text Available The complexity of mechatronic products such as climate chamber subsystems results in enormous difficulties in understanding where the main design process inefficiencies are. It is therefore extremely difficult to determine which improvements will have the most significant impact on a company or on a specific project. Mechatronic products are characterized by a high level of interdisciplinarity and complexity in the technical system and the relevant development processes. The main challenge in this respect is how to deal with the high complexity of and a variety of interdependencies in such products. We are therefore presenting a framework for integrated mechatronic product and process modelling - extended M-FBFP framework. This framework provides different independent perspectives of the overall product to improve their architecture. As a result of the proposed framework, risk analysis through subsystems in the components domain and through processes in the technical processes domain is enabled and it is now possible to provide feedback on product architecture. To obtain optimally robust product architectures from available alternative solutions, an evaluation analysis was performed across all stages, including the initialization and subsequent refinements with several evaluation criteria: complexity, interdependency and process duration. To test the validity of the proposed framework, we are presenting a case study involving a climate chamber with heat regeneration.

  14. System design in an evolving system-of-systems architecture and concept of operations

    Science.gov (United States)

    Rovekamp, Roger N., Jr.

    Proposals for space exploration architectures have increased in complexity and scope. Constituent systems (e.g., rovers, habitats, in-situ resource utilization facilities, transfer vehicles, etc) must meet the needs of these architectures by performing in multiple operational environments and across multiple phases of the architecture's evolution. This thesis proposes an approach for using system-of-systems engineering principles in conjunction with system design methods (e.g., Multi-objective optimization, genetic algorithms, etc) to create system design options that perform effectively at both the system and system-of-systems levels, across multiple concepts of operations, and over multiple architectural phases. The framework is presented by way of an application problem that investigates the design of power systems within a power sharing architecture for use in a human Lunar Surface Exploration Campaign. A computer model has been developed that uses candidate power grid distribution solutions for a notional lunar base. The agent-based model utilizes virtual control agents to manage the interactions of various exploration and infrastructure agents. The philosophy behind the model is based both on lunar power supply strategies proposed in literature, as well as on the author's own approaches for power distribution strategies of future lunar bases. In addition to proposing a framework for system design, further implications of system-of-systems engineering principles are briefly explored, specifically as they relate to producing more robust cross-cultural system-of-systems architecture solutions.

  19. Rule-based graph theory to enable exploration of the space system architecture design space

    Science.gov (United States)

    Arney, Dale Curtis

    The primary goal of this research is to improve upon system architecture modeling in order to enable the exploration of design space options. A system architecture is the description of the functional and physical allocation of elements and the relationships, interactions, and interfaces between those elements necessary to satisfy a set of constraints and requirements. The functional allocation defines the functions that each system (element) performs, and the physical allocation defines the systems required to meet those functions. Trading the functionality between systems leads to the architecture-level design space that is available to the system architect. The research presents a methodology that enables the modeling of complex space system architectures using a mathematical framework. To accomplish the goal of improved architecture modeling, the framework meets five goals: technical credibility, adaptability, flexibility, intuitiveness, and exhaustiveness. The framework is technically credible, in that it produces an accurate and complete representation of the system architecture under consideration. The framework is adaptable, in that it provides the ability to create user-specified locations, steady states, and functions. The framework is flexible, in that it allows the user to model system architectures to multiple destinations without changing the underlying framework. The framework is intuitive for user input while still creating a comprehensive mathematical representation that maintains the necessary information to completely model complex system architectures. Finally, the framework is exhaustive, in that it provides the ability to explore the entire system architecture design space. After an extensive search of the literature, graph theory presents a valuable mechanism for representing the flow of information or vehicles within a simple mathematical framework. Graph theory has been used in developing mathematical models of many transportation and

    2012-02-01

    Full Text Available The development of the architectural program in the design studio faces several difficulties. The purpose of the program is to describe the conditions where the building being designed will operate; this requires a lot of information and organization. Due to its complexity, the architetural program definition in the disciplines of design is often simplified. This article discusses such issue and proposes a computer application (SINFORMA that gathers information about the building and the theme of the project in order to develop the architectural program based on structures proposed by bibliographic references. The SINFORMA is composed by a framework which includes a data base and modules which analyze and organize functional requirements, according to the Problem Seeking method and the contemporary values of architecture enumerated by Hershberger. It is discussed how the application can be applied in design education and how it offers students a practical approach and a comprehensive data analysis for the design of built environment.

    2016-01-01

    Research into complexities of software systems Fault Management (FM) and how architectural design decisions affect safety, preservation of assets, and maintenance of desired system functionality has coalesced into a technical reference (TR) suite that advances the provision of safety and mission assurance. The NASA Independent Verification and Validation (IVV) Program, with Software Assurance Research Program support, extracted FM architectures across the IVV portfolio to evaluate robustness, assess visibility for validation and test, and define software assurance methods applied to the architectures and designs. This investigation spanned IVV projects with seven different primary developers, a wide range of sizes and complexities, and encompassed Deep Space Robotic, Human Spaceflight, and Earth Orbiter mission FM architectures. The initiative continues with an expansion of the TR suite to include Launch Vehicles, adding the benefit of investigating differences intrinsic to model-based FM architectures and insight into complexities of FM within an Agile software development environment, in order to improve awareness of how nontraditional processes affect FM architectural design and system health management.

  15. Moral architecture: the influence of the York Retreat on asylum design.

    Science.gov (United States)

    Edginton, B

    1997-06-01

    Institutional and architectural history places the asylum alongside the prison and other institutional types whose architectural characteristics emphasized confinement and control. This history obfuscates important differences in how ideas about treatment were represented in the particular design of these institutions; in other words, how the structure of a place became part of its discourse. What becomes obvious in nineteenth-century, asylum architecture is the influence of a small Yorkshire private asylum built by a Quaker, William Tuke, in 1796. The York Retreat, in form, solidified the ideas of 'moral treatment' in design and in turn assumed an exalted character in the design of late nineteenth-century asylums. Every researcher working in the field of the history of insanity acknowledges the importance of this event and its impact on the discourse of insanity for the century to follow. Few however talk about how its unique design was incorporated as part of this discourse. PMID:10671006
