    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.

    2012-01-01

    peer-reviewed Current techniques for modelling software architecture do not provide sufficient support for modelling of architectural design rules. This is a problem in the context of Model-Driven Development in which it is assumed that major design artefacts are represented as formal or semi-formal models. This paper addresses this problem by presenting an approach to modelling architectural design rules in UML at the abstraction level of the meaning of the rules. The high abstraction lev...

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

    Science.gov (United States)

    Arney, Dale Curtis

    network flow problems in the past, where nodes represent physical locations and edges represent the means by which information or vehicles travel between those locations. In space system architecting, expressing the physical locations (low-Earth orbit, low-lunar orbit, etc.) and steady states (interplanetary trajectory) as nodes and the different means of moving between the nodes (propulsive maneuvers, etc.) as edges formulates a mathematical representation of this design space. The selection of a given system architecture using graph theory entails defining the paths that the systems take through the space system architecture graph. A path through the graph is defined as a list of edges that are traversed, which in turn defines functions performed by the system. A structure to compactly represent this information is a matrix, called the system map, in which the column indices are associated with the systems that exist and row indices are associated with the edges, or functions, to which each system has access. Several contributions have been added to the state of the art in space system architecture analysis. The framework adds the capability to rapidly explore the design space without the need to limit trade options or the need for user interaction during the exploration process. The unique mathematical representation of a system architecture, through the use of the adjacency, incidence, and system map matrices, enables automated design space exploration using stochastic optimization processes. The innovative rule-based graph traversal algorithm ensures functional feasibility of each system architecture that is analyzed, and the automatic generation of the system hierarchy eliminates the need for the user to manually determine the relationships between systems during or before the design space exploration process. Finally, the rapid evaluation of system architectures for various mission types enables analysis of the system architecture design space for multiple

    In the design of very well-insulated homes, there is a need for a more nuanced design that takes into account winter and summer conditions. In this paper, we compare a traditional design for a typical Danish single-family house with large glazing areas oriented towards the south and smaller glazing...... areas towards the north, and a design with an even window distribution where the glazing-to-floor ratio is the same for each room. We found that the use of solar gains through south-oriented windows is not as important as is traditionally believed because, in well-insulated homes, space heating demand...

Last the place of architectural design within design theory is discussed.

  9. Towards computerizing intensive care sedation guidelines: design of a rule-based architecture for automated execution of clinical guidelines

    Directory of Open Access Journals (Sweden)

    2010-01-01

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

    Full Text Available In this paper we will compose the design patterns which will satisfy the properties of autonomic computingsystem: for the Decision-Making phase we will introduce Case-Based Reasoning design pattern, and forReconfiguration phase we will introduce Reactor design pattern. The most important proposal in ourcomposite design pattern is that we will use the Association Rule Learning method of Data Mining to learnabout new services that can be added along with the requested service to make the service as a dynamiccomposition of two or more services. Then we will include the new service as an aspectual feature modulecode without interrupting the user.As far as we know, there are no studies on composition of designpatterns and pattern languages for autonomic computing domain. We will authenticate our work by asimple case study work. A simple Class and Sequence diagrams are depicted.

  11. 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.

  1. Software design by reusing architectures

    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.

  2. Generative design in architecture using an expert system

    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.

    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

  10. Shape grammar in contemporary architectural theory and design

    Directory of Open Access Journals (Sweden)

    Tepavčević Bojan

    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

    Beličák, Miroslav; Pokorný, Jaroslav; Richta, Karel

    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.

    Freeform shapes and structures with a high geometric complexity play an increasingly important role in contemporary architecture. While digital models are easily created, the actual fabrication and construction remains a challenge. This is the source of numerous research problems many of which fall into the area of Geometric Computing and form part of a recently emerging research area, called "Architectural Geometry". The present paper provides a short survey of research in Architectural Geometry and shows how this field moves towards a new direction in Geometric Modeling which aims at combining shape design with important aspects of function and fabrication. © 2013 Kim Williams Books, Turin.

    2015-01-01

    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? By reporting on the latest bionic design methods and using extensive artwork, the book guides readers through the field of nature-inspired architecture, offering an extraordinary resource for pro...

    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.

In this paper, the ergonomics perspective is revisited which hence focuses on the conditional factors involving organisational, psychological, social and population as a whole. 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.

    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.

    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.

  13. 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.

  16. 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.

    2013-01-01

    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...

    Badr, Yasmine; Ma, Ko-wei; Gupta, Puneet

    2014-10-01

    With the use of subwavelength photolithography, some layouts can have low printability and, accordingly, low yield due to the existence of bad patterns even though they pass design rule checks. A reasonable approach is to select some of the candidate bad patterns as forbidden. These are the ones with a high yield impact or low routability impact, and these are to be prohibited in the design phase. The rest of the candidate bad patterns may be fixed in the postroute stage in a best-effort manner. The process developers need to optimize the process to be friendly to the patterns of high routability impact. Hence, an evaluation method is required early in the process to assess the impact of forbidding layout patterns on routability. We propose pattern-driven design rule evaluation (pattern-DRE), which can be used to evaluate the importance of patterns for the routability of the standard cells and, accordingly, select the set of bad patterns to forbid in the design. The framework can also be used to compare restrictive patterning technologies [e.g., litho-etch-litho-etch (LELE), self-aligned double patterning (SADP), self-aligned quadruple patterning (SAQP), self-aligned octuple patterning (SAOP)]. Given a set of design rules and a set of forbidden patterns, pattern-DRE generates a set of virtual standard cells; then it finds the possible routing options for each cell without using any of the forbidden patterns. Finally, it reports the routability metrics. We present a few studies that illustrate the use cases of the framework. The first study compares LELE to SADP by using a set of forbidden patterns that are allowed by LELE but not by SADP. Another study compares LELE to extreme ultraviolet lithography from the routability aspect by prohibiting patterns that have LELE native conflicts. In addition, we present a study that investigates the effect of placing the active area of the transistors close to the P/N interface instead of close to the power rails.

    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

    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.

  11. Replacing design rules in the VLSI design cycle

    Science.gov (United States)

    Hurley, Paul; Kryszczuk, Krzysztof

    2012-03-01

    We make a case for the migration of Design Rule Check (DRC), the first step in the modern VLSI design process, to a model-based system. DRC uses a large set of rules to determine permitted designs. We argue that it is a legacy of the past: slow, labor intensive, ad-hoc, inaccurate and too restrictive. We envisage the replacement of DRC and printability simulation by a signal processing and machine learning-based approach for 22nm technology nodes and beyond. Such a process would produce fast, accurate, autonomous printability prediction for optical lithography. As such, we built a proof-of-concept demonstrator that can predict OPC problems using a trained classifier without the need to fall back on costly first-principle simulation. For one sample test site, and for the OPC Line Width error type OPC violation marker, the demonstrator obtained an Equal Error Rate of ca. 4%.

    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

    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.

    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.

    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.

    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.

    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.

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 ...

    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.

    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.

  11. Architecture of Gothic Period and Its Effect to Clothing Design

    Directory of Open Access Journals (Sweden)

    Şerife YILDIZ

    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.

  12. Evolutionary Design of Rule Changing Artificial Society Using Genetic Algorithms

    Science.gov (United States)

    Wu, Yun; Kanoh, Hitoshi

    Socioeconomic phenomena, cultural progress and political organization have recently been studied by creating artificial societies consisting of simulated agents. In this paper we propose a new method to design action rules of agents in artificial society that can realize given requests using genetic algorithms (GAs). In this paper we propose an efficient method for designing the action rules of agents that will constitute an artificial society that meets a specified demand by using a GAs. In the proposed method, each chromosome in the GA population represents a candidate set of action rules and the number of rule iterations. While a conventional method applies distinct rules in order of precedence, the present method applies a set of rules repeatedly for a certain period. The present method is aiming at both firm evolution of agent population and continuous action by that. Experimental results using the artificial society proved that the present method can generate artificial society which fills a demand in high probability.

  13. Mapping Rule-Based And Stochastic Constraints To Connection Architectures: Implication For Hierarchical Image Processing

    Science.gov (United States)

    Miller, Michael I.; Roysam, Badrinath; Smith, Kurt R.

    1988-10-01

    Essential to the solution of ill posed problems in vision and image processing is the need to use object constraints in the reconstruction. While Bayesian methods have shown the greatest promise, a fundamental difficulty has persisted in that many of the available constraints are in the form of deterministic rules rather than as probability distributions and are thus not readily incorporated as Bayesian priors. In this paper, we propose a general method for mapping a large class of rule-based constraints to their equivalent stochastic Gibbs' distribution representation. This mapping allows us to solve stochastic estimation problems over rule-generated constraint spaces within a Bayesian framework. As part of this approach we derive a method based on Langevin's stochastic differential equation and a regularization technique based on the classical autologistic transfer function that allows us to update every site simultaneously regardless of the neighbourhood structure. This allows us to implement a completely parallel method for generating the constraint sets corresponding to the regular grammar languages on massively parallel networks. We illustrate these ideas by formulating the image reconstruction problem based on a hierarchy of rule-based and stochastic constraints, and derive a fully parallelestimator structure. We also present results computed on the AMT DAP500 massively parallel digital computer, a mesh-connected 32x32 array of processing elements which are configured in a Single-Instruction, Multiple Data stream architecture.

    Crosscutting concerns such as logging,security,and transaction,are well supported in the programming level by aspect-oriented programming technologies.However,addressing these issues in the high-level architecture design still remains open.This paper presents a novel approach to supporting crosscutting concern modelling in the software architecture design of component-based systems.We introduce a new element named "Aspect"into our architecture description language,ABC/ADL,to clearly model the behavior of crosscutting concerns.Aspect is the first class entity as Component and Connector in ABC/ADL.ABC/ADL Connectors provide the weaving points where the component and aspect crosscut.This approach effectively enables "separation of concerns" in high-level architecture design,and facilitates black-box reuse of COTS components.

    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)

  20. 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.

    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.

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

    Institute of Scientific and Technical Information of China (English)

    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.

    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. We provide a solution that can be quickly adopte...

  10. Designing Capital-Intensive Systems with Architectural and Operational Flexibility Using a Screening Model

    Science.gov (United States)

    Lin, Jijun; de Weck, Olivier; de Neufville, Richard; Robinson, Bob; MacGowan, David

    Development of capital intensive systems, such as offshore oil platforms or other industrial infrastructure, generally requires a significant amount of capital investment under various resource, technical, and market uncertainties. It is a very challenging task for development co-owners or joint ventures because important decisions, such as system architectures, have to be made while uncertainty remains high. This paper develops a screening model and a simulation framework to quickly explore the design space for complex engineering systems under uncertainty allowing promising strategies or architectures to be identified. Flexibility in systems’ design and operation is proposed as a proactive means to enable systems to adapt to future uncertainty. Architectural and operational flexibility can improve systems’ lifecycle value by mitigating downside risks and capturing upside opportunities. In order to effectively explore different flexible strategies addressing a view of uncertainty which changes with time, a computational framework based on Monte Carlo simulation is proposed in this paper. This framework is applied to study flexible development strategies for a representative offshore petroleum project. The complexity of this problem comes from multi-domain uncertainties, large architectural design space, and structure of flexibility decision rules. The results demonstrate that architectural and operational flexibility can significantly improve projects’ Expected Net Present Value (ENPV), reduce downside risks, and improve upside gains, compared to adopting an inflexible strategy appropriate to the view of uncertainty at the start of the project. In this particular case study, the most flexible strategy improves ENPV by 85% over an inflexible base case.

    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.

  15. A Design rule language for aspect-oriented programming

    OpenAIRE

    Costa Neto, Alberto; Marques, Arthur; Gheyi, Rohit; Borba, Paulo; Castor Filho, Fernando

    2009-01-01

    Aspect-Oriented Programming is known as a technique for modularizing crosscutting concerns. However, constructs aimed to support crosscutting modularity might actually break class modularity. This can be mitigated by using adequate Design Rules between classes and aspects. We present a language that supports most of the Design Rules found in AO Systems, making easy to express and verify them automatically. We discuss how our language improves crosscutting modularity without breaking cla...

    2016-06-01

    Full Text Available The mosque constitutes one of the most highly developed forms of religious architecture. With the rapid expansion of the Muslim community through conquests as well as missionary activities, it became necessary to set aside an enclosed area in cities or large towns for the purpose of established communal worship. Mosque architecture in the Muslim period exposes clearly its sacred identity, even it is continuously remarked, but in secular architecture, the ideas are not spiritually motivated in a cosmic sense. Definitely a structural idea and use of materials as well as its functional and aesthetic use play a role in determining what is expressed by it. The development of understanding of functional and aesthetic use of materials and technique with effective manner is depending on assimilated technologies. Integrated process of standard materials, skilled labor, innovative idea and socioeconomic as well as geographical factors may regard to constructing any magnificent architecture. The present study is an attempt to analyse and develop the structure, structural decoration and use of materials and design of the mosques during the Muslim period in Bengal.

  10. 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.

    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.

    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.

  11. Scaling to Nanotechnology Limits with the PIMS Computer Architecture and a new Scaling Rule.

    Energy Technology Data Exchange (ETDEWEB)

    Debenedictis, Erik

    2015-02-01

    We describe a new approach to computing that moves towards the limits of nanotechnology using a newly formulated sc aling rule. This is in contrast to the current computer industry scali ng away from von Neumann's original computer at the rate of Moore's Law. We extend Moore's Law to 3D, which l eads generally to architectures that integrate logic and memory. To keep pow er dissipation cons tant through a 2D surface of the 3D structure requires using adiabatic principles. We call our newly proposed architecture Processor In Memory and Storage (PIMS). We propose a new computational model that integrates processing and memory into "tiles" that comprise logic, memory/storage, and communications functions. Since the programming model will be relatively stable as a system scales, programs repr esented by tiles could be executed in a PIMS system built with today's technology or could become the "schematic diagram" for implementation in an ultimate 3D nanotechnology of the future. We build a systems software approach that offers advantages over and above the technological and arch itectural advantages. Firs t, the algorithms may be more efficient in the conventional sens e of having fewer steps. Second, the algorithms may run with higher power efficiency per operation by being a better match for the adiabatic scaling ru le. The performance analysis based on demonstrated ideas in physical science suggests 80,000 x improvement in cost per operation for the (arguably) gene ral purpose function of emulating neurons in Deep Learning.

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

    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. The use of roles to control access

  15. Extraction of design rules from multi-objective design exploration (MODE) using rough set theory

    International Nuclear Information System (INIS)

    Multi-objective design exploration (MODE) and its application for design rule extraction are presented. MODE reveals the structure of design space from the trade-off information. The self-organizing map (SOM) is incorporated into MODE as a visual data-mining tool for design space. SOM divides the design space into clusters with specific design features. The sufficient conditions for belonging to a cluster of interest are extracted using rough set theory. The resulting MODE was applied to the multidisciplinary wing design problem, which revealed a cluster of good designs, and we extracted the design rules of such designs successfully.

    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

  19. The Function of Gesture in an Architectural Design Meeting

    CERN Document Server

    Visser, Willemien

    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...

  20. A quantitative approach to nonlinear IC process design rule scaling

    Science.gov (United States)

    Gold, Spencer Montgomery

    As minimum dimensions in integrated circuit technologies are reduced beyond 0.1 m m, linear process scaling becomes more difficult and costly. Exponentially rising manufacturing facility and process scaling costs can be better managed by performing nonlinear process shrinks. Nonlinear scaling allows the horizontal design rules to be reduced by different factors according to their ability to provide area and performance improvement in a cost effective manner. This thesis describes a methodology and CAD tools for use in selecting nonlinear design rule reduction ratios that make effective tradeoffs between die cost and performance. The cost effectiveness of nonlinear scaling is demonstrated for a complementary GaAs (CGaAsTM) process. CGaAs is a young technology with coarse design rules that would benefit significantly from a nonlinear shrink. The cost/benefit analysis for scaling the design rules is based on a process-independent optimizing SRAM compiler which was developed as part of this work. The methodology for nonlinear scaling includes identifying the rules which have the greatest impact on circuit area and analyzing the area and performance improvements as these rules are scaled through a range of practical scale factors. Benefit data (product of power and delay improvement ratios) is then combined with die cost estimates at each step to yield the cost/benefit ratio, a quantitative metric for design rule reduction. The slopes and inflection points of cost/benefit vs. scale factor plots guide process engineers in selecting reduction ratios for the various design rules. This procedure should be repeated, using the results of one pass as the starting point for the next. The cost/benefit analysis methodology compares embedded static RAMs that are generated by the PUMA process-independent SRAM compiler. This compiler, which is based on Duet's MasterPortTM layout compactor, can create optimized SRAM cell libraries for any complementary technology. It is capable of

    The computerization of Intensive Care Units provides an overwhelming amount of electronic data for both medical and financial analysis. However, the current tarification, which is the process to tick and count patients' procedures, is still a repetitive, time-consuming process on paper. Nurses and secretaries keep track manually of the patients' medical procedures. This paper describes the design methodology and implementation of automated tarification services. In this study we investigate if the tarification can be modeled in service oriented architecture as a composition of interacting services. Services are responsible for data collection, automatic assignment of records to physicians and application of rules. Performance is evaluated in terms of execution time, cost evaluation and return on investment based on tracking of real procedures. The services provide high flexibility in terms of maintenance, integration and rules support. It is shown that services offer a more accurate, less time-consuming and cost-effective tarification.

  14. 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.

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

    Science.gov (United States)

    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

    2013-09-01

    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.

  17. An Architectural Design for Brokered Collaborative Content Delivery System

    2010-01-01

    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...

    2016-09-20

    We propose a class of randomized trial designs aimed at gaining the advantages of wider generalizability and faster recruitment while mitigating the risks of including a population for which there is greater a priori uncertainty. We focus on testing null hypotheses for the overall population and a predefined subpopulation. Our designs have preplanned rules for modifying enrollment criteria based on data accrued at interim analyses. For example, enrollment can be restricted if the participants from a predefined subpopulation are not benefiting from the new treatment. Our designs have the following features: the multiple testing procedure fully leverages the correlation among statistics for different populations; the asymptotic familywise Type I error rate is strongly controlled; for outcomes that are binary or normally distributed, the decision rule and multiple testing procedure are functions of the data only through minimal sufficient statistics. Our designs incorporate standard group sequential boundaries for each population of interest; this may be helpful in communicating the designs, because many clinical investigators are familiar with such boundaries, which can be summarized succinctly in a single table or graph. We demonstrate these designs through simulations of a Phase III trial of a new treatment for stroke. User-friendly, free software implementing these designs is described.

    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

    Architectural acoustics design has in the past been based on simple design rules. However, with a growing complexity in architectural acoustics and the emergence of room acoustic simulation programmes with considerable potential, it is now possible to subjectively analyse and evaluate acoustic properties prior to the actual construction of a building. With the right tools applied, acoustic design can become an integral part of the architectural design process. The aim of this paper is to inve...

  11. A spatially augmented reality sketching interface for architectural daylighting design.

    Science.gov (United States)

    Sheng, Yu; Yapo, Theodore C; Young, Christopher; Cutler, Barbara

    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

  12. Design rules for superconducting analog-digital transducers

    International Nuclear Information System (INIS)

    This Thesis is a contribution for dimensioning aspects of circuits designs in superconductor electronics. Mainly superconductor comparators inclusive Josephson comparators as well as QOJS-Comparators are investigated. Both types were investigated in terms of speed and sensitivity. The influence of the thermal noise on the decision process of the comparators represent in so called gray zone, which is analysed in this thesis. Thereby, different relations between design parameters were derived. A circuit model of the Josephson comparator was verified by experiments. Concepts of superconductor analog-to-digital converters, which are based on above called comparators, were investigated in detail. From the comparator design rules, new rules for AD-converters were derived. Because of the reduced switching energy, the signal to noise ratio (SNR) of the circuits is affected and therefore the reliability of the decision-process is affected. For special applications with very demanding requirements in terms of the speed and accuracy superconductor analog-to-digital converters offer an excellent performance. This thesis provides relations between different design paramenters and shows resulting trade-offs, This method is transparent and easy to transfer to other circuit topologies. As a main result, a highly predictive tool for dimensioning of superconducting ADC's is proved.

    2016-03-01

    Directed self-assembly (DSA), the epitaxial alignment of block copolymers to minimize the system free energy, is prone to defects that are random and difficult to eliminate. When creating fins for FinFET devices, the defect density is known to be a strong function of guide pattern CD. We propose the use of a restricted design rule (RDR) that limits the guide pattern CD to achieve low defectivity, and also report its impact on overall chip area and design-ability of logic, analog IO, and SRAM. The restricted design rule in defining guide pattern CD is extracted from empirical data. Design rule check (DRC) is applied to GLOBALFOUNDRIES' technology chip design to estimate the penalty of DSA RDR on fin layer.

    2011-12-01

    The manned mission to Mars is expected to last almost three years. A human factor must be taken seriously into account in such a long-term mission. 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. 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

    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.

    Self-assembling RNA molecules present compelling substrates for the rational interrogation and control of living systems. However, imperfect in silico models--even at the secondary structure level--hinder the design of new RNAs that function properly when synthesized. Here, we present a unique and potentially general approach to such empirical problems: the Massive Open Laboratory. The EteRNA project connects 37,000 enthusiasts to RNA design puzzles through an online interface. Uniquely, EteRNA participants not only manipulate simulated molecules but also control a remote experimental pipeline for high-throughput RNA synthesis and structure mapping. We show herein that the EteRNA community leveraged dozens of cycles of continuous wet laboratory feedback to learn strategies for solving in vitro RNA design problems on which automated methods fail. The top strategies--including several previously unrecognized negative design rules--were distilled by machine learning into an algorithm, EteRNABot. Over a rigorous 1-y testing phase, both the EteRNA community and EteRNABot significantly outperformed prior algorithms in a dozen RNA secondary structure design tests, including the creation of dendrimer-like structures and scaffolds for small molecule sensors. These results show that an online community can carry out large-scale experiments, hypothesis generation, and algorithm design to create practical advances in empirical science. PMID:24469816

    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.

    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...

    Synthetic biology is an emerging scientific field that promotes the standardized manufacturing of biological components without natural equivalents. Its goal is to create artificial living systems that can meet various needs in health care or energy domains. While most works are focused on the individual bacterium as a chemical reactor, our project, SynBioTIC, addresses a novel and more complex challenge: shape engineering; that is, the redesign of natural morphogenesis toward a new kind of developmental 3D printing. Potential applications include organ growth, natural computing in biocircuits, or future vegetal houses. To create in silico multicellular organisms that exhibit specific shapes, we construe their development as an iterative process combining fundamental collective phenomena such as homeostasis, patterning, segmentation, and limb growth. Our numerical experiments rely on the existing Escherichia coli simulator Gro, a physicochemical computation platform offering reaction-diffusion and collision dynamics solvers. The synthetic bioware of our model executes a set of rules, or genome, in each cell. Cells can differentiate into several predefined types associated with specific actions (divide, emit signal, detect signal, die). Transitions between types are triggered by conditions involving internal and external sensors that detect various protein levels inside and around the cell. Indirect communication between bacteria is relayed by morphogen diffusion and the mechanical constraints of 2D packing. Starting from a single bacterium, the overall architecture emerges in a purely endogenous fashion through a series of developmental stages, inlcuding proliferation, differentiation, morphogen diffusion, and synchronization. The genome can be parametrized to control the growth and features of appendages individually. As exemplified by the L and T shapes that we obtain, certain precursor cells can be inhibited while others can create limbs of varying size

    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.

  15. 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

    CERN Document Server

    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.

    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.

    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.

  6. Innovation in Deep Space Habitat Interior Design: Lessons Learned From Small Space Design in Terrestrial Architecture

    Simon, Matthew A.; Toups, Larry

    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.

  7. 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.

  10. 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.

  17. 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

    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.

  7. Recent evolutions of French design and construction rules

    International Nuclear Information System (INIS)

    This paper summarises the studies and evaluations made in order to support the recent evolutions of the French Design and Construction Rules, with the objective to improve the competitiveness of nuclear power plants. To this aim, an inquiry was conducted with Suppliers, in order to identify the topics corresponding to cost reduction potentials. Following this inquiry, the RCC-M construction code provisions which may be improved in order to reduce the cost were identified and highlighted compared to the others cost-intensive requirements falling outside the code scope. In parallel, other non-nuclear codes, such as CODAP and CODETI in France for Vessels, heat exchangers and piping, and ASME VIII were analysed in order to evaluate the possibility to refer to more standard alternatives for safety related mechanical components. In such a case, eventual complementary requirements should be specified, and some exercises of application were conducted with the suppliers on typical examples. In order to finalize the overview, return of operating experience was addressed and discussed with the Safety Authority, leading to complementary precautions, in particular on fatigue and fast fracture prevention. The corresponding revisions have been included in the 2000 edition of the RCC-M construction code. (author)

    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

  6. A Heuristic Rule-Based Passive Design Decision Model for Reducing Heating Energy Consumption of Korean Apartment Buildings

    Directory of Open Access Journals (Sweden)

    Dongjun Suh

    2014-10-01

    Full Text Available This research presents an evaluative energy model for estimating the energy efficiency of the design choices of architects and engineers in the early design phase. We analyze the effects of various parameters with different characteristics in various combinations for building energy consumption. With this analysis, we build a database that identifies a set of heuristic rules for energy-efficient building design to facilitate the design of sustainable apartment housing. Perturbation studies are based on a sensitivity analysis used to identify the thermal influence of the input design parameters on various simulation outputs and compare the results to a reference case. Energy sensitivity weight factors are obtained from an extensive sensitivity study using building energy simulations. The results of the energy sensitivity study summarized in a set of heuristic rules for evaluating architectural features are estimated through case studies of Korean apartment buildings. This study offers valuable guidelines for developing energy-efficient residential housing in Korea and will help architects in considering appropriate design schemes and provide a ready reference to generalized test cases for both architects and engineers so that they can zero in on a set of effective design solutions.

    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.

  8. 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.

  12. 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.

  13. Climate-conscious architecture. Design and wind testing method for climates in change

    Energy Technology Data Exchange (ETDEWEB)

    Kuismanen, K.

    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

    Directory of Open Access Journals (Sweden)

    Zbyněk Šlajchrt

    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.

    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 (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.

    2007-01-01

    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.

However, not all physical circuit implementations provide the atomic transitions needed to satisfy the atomic circuit model. This can cause operational failures in real circuits, as we illustrate. Nonetheless, circuits with non-atomic transitions can faithfully implement the atomic circuit model when comb...

    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.

    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.

  9. 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.

    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.

    Science.gov (United States)

    Bagis, Aytekin

    2008-01-01

    This paper presents an approach to fuzzy rule base design using tabu search algorithm (TSA) for nonlinear system modeling. TSA is used to evolve the structure and the parameter of fuzzy rule base. The use of the TSA, in conjunction with a systematic neighbourhood structure for the determination of fuzzy rule base parameters, leads to a significant improvement in the performance of the model. To demonstrate the effectiveness of the presented method, several numerical examples given in the literature are examined. The results obtained by means of the identified fuzzy rule bases are compared with those belonging to other modeling approaches in the literature. The simulation results indicate that the method based on the use of a TSA performs an important and very effective modeling procedure in fuzzy rule base design in the modeling of the nonlinear or complex systems.

    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.

  7. 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

    Prof. C.N. Bhoyar

    2013-03-01

    Full Text Available The advent of deep sub-micron technology has recently highlighted the criticality of the on-chip interconnects. As diminishing feature sizes have led to increases in global wiring delays, Network-on-Chip (NoC architectures are viewed as a possible solution to the wiring challenge and have recently crystallized into a significant research thrust. Both NoC performance and energy budget depend heavily on the routers' buffer resources. Network on chip is efficient on chip communication architecture for SoC architecture. This paper presents a VHDL based model of a novel bidirectional channel network-on-chip BiNoC architecture to enhance the performance of on-chip communication. By introducing a new (BiNoC organization, our design added flexibility promises better bandwidth utilization, lower packet delivery latency, and higher packet consumption rate. Novel on-chip router architecture is developed to support dynamic selfreconfiguration of the bidirectional traffic flow. This area-efficient BiNoC router delivers better performance and requires smaller buffer size than that of a conventional network-on-chip (NoC. The flow direction at each Channel is controlled by a channel direction control (CDC algorithm. This algorithm implemented with a pair of finite state machines. This CDC algorithm provided high performance, free of deadlock, and free of starvation. We implemented a parameterized register transfer level (RTL design of the NoC architecture elements.

    International Nuclear Information System (INIS)

    The purpose of this letter is to forward the Prometheus preconceptual Instrumentation and Control (I and C) system architecture (Enclosure (1)) to NR for information as part of the Prometheus closeout work. The preconceptual 1 and C system architecture was considered a key planning document for development of the I and C system for Project Prometheus. This architecture was intended to set the technical approach for the entire I and C system. It defines interfaces to other spacecraft systems, defines hardware blocks for future development, and provides a basis for accurate cost and schedule estimates. Since the system requirements are not known at this time, it was anticipated that the architecture would evolve as the design of the reactor module was matured

    Full Text Available This paper describes one of the challenging issues implied by scientific infrastructures on a mobile robot cognition architecture. For a generally applicable cognition architecture, we study the dependencies and logical relations between several tasks and subsystems. The overall view of the software modules is described, including their relationship with a fault management module that monitors the consistency of the data flow among the modules. The fault management module is the solution of the deliberative architecture for the single point failures, and the safety anchor is the reactive solution for the faults by redundant equipment. In addition, a hardware architecture is proposed to ensure safe robot movement as a redundancy for the cognition of the robot. The method is designed for a four-wheel steerable (4WS mobile manipulator (iMoro as a case study.

    2016-01-01

    This book considers two key educational tools for future generations of professionals with a space architecture background in the 21st century: (1) introducing the discipline of space architecture into the space system engineering curricula; and (2) developing space architecture as a distinct, complete training curriculum.  Professionals educated this way will help shift focus from solely engineering-driven transportation systems and “sortie” missions towards permanent off-world human presence. The architectural training teaches young professionals to operate at all scales from the “overall picture” down to the smallest details, to provide directive intention–not just analysis–to design opportunities, to address the relationship between human behavior and the built environment, and to interact with many diverse fields and disciplines throughout the project lifecycle. This book will benefit individuals and organizations responsible for planning transportation and habitat systems in space, while a...

    As the smart grid becomes reality, software architectures for integrating legacy systems with new innovative approaches for grid management are needed. These architectures must exhibit flexibility, extensibility, interoperability and scalability. In this position paper, we describe our preliminary work to design such an architecture, known as GridOPTICS, that will enable the deployment and integration of new software tools in smart grid operations. Our preliminary design is based upon use cases from PNNL’s Future Power Grid Initiative, which is a developing a collection of advanced software technologies for smart grid management and control. We describe the motivations for GridOPTICS, and the preliminary design that we are currently prototyping for several distinct use cases.

    Advanced composites have been targeted as a 'leapfrog' technology that would provide a unique global competitive position for U.S. industry. Composites are unique in the requirements for an integrated approach to designing, manufacturing, and marketing of products developed utilizing the new materials of construction. Numerous studies extending across the entire economic spectrum of the United States from aerospace to military to durable goods have identified composites as a 'key' technology. In general there have been two approaches to composite construction: build models of a given composite materials, then determine characteristics of the material via numerical simulation and empirical testing; and experience-directed construction of fabrication plans for building composites with given properties. The first route sets a goal to capture basic understanding of a device (the composite) by use of a rigorous mathematical model; the second attempts to capture the expertise about the process of fabricating a composite (to date) at a surface level typically expressed in a rule based system. From an AI perspective, these two research lines are attacking distinctly different problems, and both tracks have current limitations. The mathematical modeling approach has yielded a wealth of data but a large number of simplifying assumptions are needed to make numerical simulation tractable. Likewise, although surface level expertise about how to build a particular composite may yield important results, recent trends in the KBS area are towards augmenting surface level problem solving with deeper level knowledge. Many of the relative advantages of composites, e.g., the strength:weight ratio, is most prominent when the entire component is designed as a unitary piece. The bottleneck in undertaking such unitary design lies in the difficulty of the re-design task. Designing the fabrication protocols for a complex-shaped, thick section composite are currently very difficult. It is in

    An advanced design and implementation of a Control Architecture for Long Range Autonomous Planetary Rovers is presented using a hierarchical top-down task decomposition, and the common structure of each design is presented based on feedback control theory. Graphical programming is presented as a common intuitive language for the design when a large design team is composed of managers, architecture designers, engineers, programmers, and maintenance personnel. The whole design of the control architecture consists in the classic control concepts of cyclic data processing and event-driven reaction to achieve all the reasoning and behaviors needed. For this purpose, a commercial graphical tool is presented that includes the mentioned control capabilities. Messages queues are used for inter-communication among control functions, allowing Artificial Intelligence (AI) reasoning techniques based on queue manipulation. Experimental results show a highly autonomous control system running in real time on top the JPL micro-rover Rocky 7 controlling simultaneously several robotic devices. This paper validates the sinergy between Artificial Intelligence and classic control concepts in having in advanced Control Architecture for Long Range Autonomous Planetary Rovers.

  11. Generation and Development of RNA Ligase Ribozymes with Modular Architecture Through “Design and Selection”

    Directory of Open Access Journals (Sweden)

    2010-08-01

    Full Text Available In vitro selection with long random RNA libraries has been used as a powerful method to generate novel functional RNAs, although it often requires laborious structural analysis of isolated RNA molecules. Rational RNA design is an attractive alternative to avoid this laborious step, but rational design of catalytic modules is still a challenging task. A hybrid strategy of in vitro selection and rational design has been proposed. With this strategy termed “design and selection,” new ribozymes can be generated through installation of catalytic modules onto RNA scaffolds with defined 3D structures. This approach, the concept of which was inspired by the modular architecture of naturally occurring ribozymes, allows prediction of the overall architectures of the resulting ribozymes, and the structural modularity of the resulting ribozymes allows modification of their structures and functions. In this review, we summarize the design, generation, properties, and engineering of four classes of ligase ribozyme generated by design and selection.

  12. Revolution of Chinese architectural design at the new-type urbanization stage

    Directory of Open Access Journals (Sweden)

    Jianguo Wang

    2015-09-01

    Full Text Available Witnessing more than three decades of sustained and rapid economic growth, China has become a nation that enjoys the fastest rate of urbanization; the largest quantities of civil construction; the most obvious urban development to be “newer”, “bigger” and “higher”; and the most prosperous architectural design market worldwide. In terms of the construction industry, housing construction totals 31.3 billion square meters, occupying more than 70% of the floor area of the existing stock houses. It is safe to say that the construction industry significantly boosts GDP growth, expands the number of jobs, and improves the living conditions of the masses. Related to this is the need to end the architectural guidelines of the planned economy era economizing on food and clothing and instead step into a new historic stage allowing bold pursuit of architectural aesthetics and individuality. A group of architects who have social ideals, adhere faithfully to professional standards and pledge to pursue architectural innovation are active in China. Instead of simply converting the overwhelming opportunities brought to carry economic benefits, they dare to embrace the challenges imposed on enhancing architectural connotation and create a batch of high-level work that lives up to expectations of the era, marking the achievement of reform and rapid urbanization in China. Yet, as time goes on, the promotion of national development concepts, ideas of social consumption and the masses’ cultural level establishes new requirements for the architectural design industry, architects and architectural design works. An appeal is thus made against Chinese architects for a summary, reflection and proactive anticipation to respond to the new requirements of the era.

    Jahromi, Soheila

    1993-01-01

    This paper gives an overall view of the architectural design process and elements in taking an idea from conception to execution. The project presented is an example for this process. Once the need for a new structure is established, an architect studies the requirements, opinions and limits in creating a structure that people will exist in, move through, and use. Elements in designing a building include factors such as volume and surface, light and form changes of scale and view, movement and stasis. Some of the other factors are functions and physical conditions of construction. Based on experience, intuition, and boundaries, an architect will utilize all elements in creating a new building. In general, the design process begins with studying the spatial needs which develop into an architectural program. A comprehensive and accurate architectural program is essential for having a successful building. The most attractive building which does not meet the functional needs of its users has failed at the primary reason for its existence. To have a good program an architect must have a full understanding of the daily functions that will take place in the building. The architectural program along with site characteristics are among a few of the important guidelines in studying the form, adjacencies, and circulation for the structure itself and also in relation to the adjacent structures. Conceptual studies are part of the schematic design, which is the first milestone in the design process. The other reference points are design development and construction documents. At each milestone, review and coordination with all the consultants is established, and the user is essential in refining the project. In design development phase, conceptual diagrams take shape, and architectural, structural, mechanical, and electrical systems are developed. The final phase construction documents convey all the information required to construct the building. The design process and elements

  17. On the Design of Next Generation Network Architecture for a Developing Economy

    Directory of Open Access Journals (Sweden)

    Nathaniel S. Tarkaa

    2016-08-01

    Full Text Available The design of network architecture is an essential step in the design of Next Generation Networks, leading to the prediction of the actual equipment quantities and dimensioning of the network. The network architecture is commonly drawn out as a diagram for visual representation of the overall network. This paper focuses on the design of the architectural model for a softswitch IP based backbone network for Benue State, Nigeria, as a case study of developing economies. It has been found that, in developing countries, the migration from the Public Switched Telephone Network to Next Generation Network takes the form of a major telecommunications development scheme meant for the extension of telecommunications infrastructure and services to new deserved areas and/or the modernization of the predominantly obsolete and substandard existing telecommunications infrastructure. So, the basic network planning principles have been followed to design the architecture in the most efficient and cost-effective manner possible. The key design methodology is based on intuitive demand forecasting, a snapshot of the existing network infrastructure and systematic assessment of the Public Switched Telephone Network-to-Next Generation Network migration principles. It was furthermore guided by use of the ITU-T’s generic reference models enabling the proper combinations of the functional entities. The resulting Next Generation Network backbone architecture is made up of 2 Softswitches, 23 Universal Media Gateways and an MPLS/IP core. The further optimization of the architecture, which is normally achieved with dimensioning of the network, is beyond the scope of this work.

    Full Text Available Global economic integration increased the complexity of business activities, so organizations are forced to become more efficient each day. Process organization is a very useful way of aligning organizational systems towards business processes. However, an organization must do more than just focus its attention and efforts on processes. The layout design has also a significant impact on the system performance.. We contribute to this field by developing a tailored process-oriented organizational structure and new layout design for the quality assurance of a leading German automotive manufacturer. The target concept we developed was evaluated by process owners and an IT-based process simulation. Our results provide solid empirical back-up in which the performance and effects are  assessed from a qualitative and quantitative perspective

  7. Integrating Computer Architectures into the Design of High-Performance Controllers

    Science.gov (United States)

    Jacklin, Stephen A.; Leyland, Jane A.; Warmbrodt, William

    1986-01-01

    Modern control systems must typically perform real-time identification and control, as well as coordinate a host of other activities related to user interaction, on-line graphics, and file management. This paper discusses five global design considerations that are useful to integrate array processor, multimicroprocessor, and host computer system architecture into versatile, high-speed controllers. Such controllers are capable of very high control throughput, and can maintain constant interaction with the non-real-time or user environment. As an application example, the architecture of a high-speed, closed-loop controller used to actively control helicopter vibration will be briefly discussed. Although this system has been designed for use as the controller for real-time rotorcraft dynamics and control studies in a wind-tunnel environment, the control architecture can generally be applied to a wide range of automatic control applications.

  8. Building a prototype of a Martian base in Poland, an architectural design overview and progress report

    Science.gov (United States)

    Kozicki, Janek

    This talk focuses on recent advances in the construction of a prototype 1000 m2 Martian out-post for 8 inhabitants. The architectural design for such a Martian base has been presented previously on COSPAR 2008, the presentation being entitled ,,Architectural design proposal for a Martian base to continue NASA Mars Design Reference Mission". The presentation was welcomed with warm interest by various institutions, some of which offered help in building a prototype such as providing the building site or funding. This year's oral presentation will focus on a progress report and will briefly describe the architectural design. The architectural design is inspired by terrestrial pneumatic architecture. It has small volume, can be easily transported and provides a large habitable space. An architectural solution analo-gous to a terrestrial house with a studio and a workshop was assumed. The spatial placement of the following zones was carefully considered: residential, agricultural and science, as well as garage and workshop. Further attention was paid to transportation routes and a control and communications center. The issues of a 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 one and a half year. An Open Plan architectural solution was assumed, 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. The prototype of such a Polish-origin Martian outpost will be used in a manner similar to MDRS or FMARS but to a larger extent. The prototype's design itself will be tested and corrected to achieve a design which can be used on Mars. The procedure of unfolding the pneumatic modules and floor leveling will be tested. The 1000 m2 interior will be used for various simulation exercises: socio-psychological testing, interior arrangement experiments

    2011-07-01

    This paper addresses different market design options for meshed offshore grids. An offshore wind farm can either be affiliated to an onshore zone or be an independent zone under implicit nodal pricing. Under feed-in tariffs and price premiums, the offshore wind farm's and TSO incentives are contrasted. It is demonstrated that in a number of cases, bidding a different amount than expected wind generation into day-ahead markets can be advantageous for a single actor. In practice, the conceptual considerations depend strongly on price differentials between markets neighbouring the offshore grid. The offshore wind farm may have an incentive to withhold generation for spot markets under nodal pricing because this opens access to higher-price markets. The authors conclude that specific offshore grid market designs should be discussed to ensure that socio-economically optimal outcomes are achieved under all possible constellations. (orig.)

    2013-01-01

    Architectural prototyping is a widely used practice, con- cerned with taking architectural decisions through experiments with light- weight implementations. However, many architectural decisions are only taken when systems are already (partially) implemented. This is prob- lematic in the context of...... architectural prototyping since experiments with full systems are complex and expensive and thus architectural learn- ing is hindered. In this paper, we propose a novel technique for harvest- ing architectural prototypes from existing systems, \\architectural slic- ing", based on dynamic program slicing. Given a...... system and a slicing criterion, architectural slicing produces an architectural prototype that contain the elements in the architecture that are dependent on the ele- ments in the slicing criterion. Furthermore, we present an initial design and implementation of an architectural slicer for Java....

    2004-01-01

    There are continuous needs for engineering organizations to improve their design process. Current state of the art techniques use computational simulations to predict design performance, and optimize it through advanced design methods. These tools have been used mostly by individual engineers. This paper presents an architecture for achieving results at an organization level beyond individual level. The next set of gains in process improvement will come from improving the effective use of computers and software within a whole organization, not just for an individual. The architecture takes advantage of state of the art capabilities to produce a Web based system to carry engineering design into the future. To illustrate deployment of the architecture, a case study for implementing advanced multidisciplinary design optimization processes such as Bi-Level Integrated System Synthesis is discussed. Another example for rolling-out a design process for Design for Six Sigma is also described. Each example explains how an organization can effectively infuse engineering practice with new design methods and retain the knowledge over time.

An architectural prototype is primarily a learning and communication vehicle used to explore and experiment with alternative architectural styles, features, and patterns in order to balance different architectural qualities. The use of architectural...... prototypes in the development process is discussed, and we argue that such prototypes can play a role throughout the entire process. The use of architectural prototypes is illustrated by three distinct cases of creating software systems. We argue that architectural prototyping can provide key insights that...

    2005-01-01

    This paper presents a design method of ByPassing Unit(BPU) in 32-bit Digital Signal Processor(DSP)-MD32. MD32 is realized in 0,18μm technology, 1.8V and 200 MHz working clock. It focuses on the Reduced Instruction Set Computer(RISC) architecture and DSP computation capability thoroughly, extends DSP with various addressing modes in a customized DSP pipeline stage architecture. The paper also discusses the architecture and circuit design of bypassing logic to fit MD32 architecture. The parallel execution of BPU with instruction decode in architecture level is applied to reduce time delay. The optimization of circuit that serial select with priority is analyzed in detail, and the result shows that about half of time delay is reduced after this optimization. Examples show that BPU is useful for improving the DSP's performance.The forwarding logic in MD32 realizes 8 data channels feedback and meets the working clock limit.

  19. Design trade-offs in ADC architectures dedicated to uncooled focal plane arrays

    Robert, P.; Dupont, B.; Pochic, D.

    2008-04-01

    This paper presents two different architectures for the design of Analog to Digital Converters specifically adapted to infrared bolometric image sensors. Indeed, the increasing demand for integrated functions in uncooled readout circuits leads to on-chip ADC design as an interface between the internal analog core and the digital processing electronics. However specifying an on-chip ADC dedicated to focal plane array raises many questions about its architecture and its performance requirements. We will show that two architecture approaches are needed to cover the different sensor features in terms of array size and frame speed. A monolithic 14 bits ADC with a pipeline architecture, and a column 13 bits ADC with an original dual-ramp architecture, will be described. Finally, we will show measurement results to confirm the monolithic ADC is suitable for small array, as 160 x 120 with low frame speed, while a column ADC is more compliant for higher array, as 640 x 480 with a 60 Hz frame speed or 1024 x 768 arrays.

    The design of user interfaces is a step which takes a long time. The automatic generation of these interfaces induces shorter durations. With this automatic generation, the UIDLs have appeared. They allow specifying an interface using a Description Language. A step which also takes a long time is the redesigning of the user interface to take into accounts users remarks. We propose to use the operators of the tree algebra with a UIDL as UsiXML which is structured as a tree to improve this step...

  1. Importance of building maintenance at the time of architectural design of buildings rehabilitated with heritage value

    Institute of Scientific and Technical Information of China (English)

    Rui Calejo Rodrigues; Patrícia Fernandes Rocha

    2011-01-01

    During architectural conception phase,building maintenance problematic is mostly a result of the unintentional use of preconceived architectonical solutions rather than a consequence of a specific influence of maintenance requirements.Hardly the architect in the act of design understands the importance of these solutions in the service life span of a building.Being aware of this,is it possible for the architect to be supplied with a decision support system that allows him to consider the implications of building maintenance since the early design phases? Having awareness of this problem and its consequences in the early design phases a research project was started at the Faculty Engineering of the University of Oporto(FEUP),under which the implications of building maintenance in the act of architectural design is studied.This article presents the methodology developed to identify the needs of maintenance of buildings based on a DSS-decision support system that provides simple tools the architect can use in design phase.This methodology is based on decomposition of building parts-Elements Source of Maintenance ESM-,and subsequently,a set of functional requirements that determine the performance regarding building maintenance on account of architectural decisions.Relevant maintenance actions are defined:Inspection,Pro-action,Cleaning,Correction,Replacement,Legal enforcement,Limits of use.One can thus set up a relationship between the act of design and its performance framework based on behavior,intervention and the ownership of the work of architecture.Using a Multicriteria Analysis (MCA) a qualitative evaluation of different options based on maintenance requirements accomplishment.Conclusions on the importance of architectural conception concerning the building maintenance were clearly arrived at and the utility of the developed decision support tool was also highlighted.

  2. Intersecting Knowledge Fields and Integrating Data-Driven Computational Design en Route to Performance-Oriented and Intensely Local Architectures

    Directory of Open Access Journals (Sweden)

    Michael U Hensel

    2014-11-01

    Full Text Available This paper discusses research by design efforts in architectural education, focused on developing concepts and methods for the design of performance-oriented and intensely local architectures. The pursued notion of performance foregrounds the interaction between a given architecture and its local setting, with consequences not only for the design product but also for the related processes by which it is generated. Integrated approaches to data-driven computational design serve to generate such designs. The outlined approach shifts the focus of design attention away from the delivery of finite architectural objects and towards an expanded range of architecture-environment interactions that are registered, instrumentalised and modulated over time. This paper examines ongoing efforts in integrating specific architectural goals and approaches, computational data-driven design methods and generative design processes, based on a range of context-specific and often real-time data sets. The work discussed is produced in the context of the Research Centre for Architecture and Tectonics (RCAT and the Advanced Computational Design Laboratory (ACDL at the Oslo School of Architecture and Design.

    EChO is a three-modules (VNIR, SWIR, MWIR), highly integrated spectrometer, covering the wavelength range from 0.55 μ m to 11.0 μ m. The baseline design includes the goal wavelength extension to 0.4 μ m while an optional LWIR module extends the range to the goal wavelength of 16.0 μ m. An Instrument Control Unit (ICU) is foreseen as the main electronic subsystem interfacing the spacecraft and collecting data from all the payload spectrometers modules. ICU is in charge of two main tasks: the overall payload control ( Instrument Control Function) and the housekeepings and scientific data digital processing ( Data Processing Function), including the lossless compression prior to store the science data to the Solid State Mass Memory of the Spacecraft. These two main tasks are accomplished thanks to the Payload On Board Software (P-OBSW) running on the ICU CPUs.

  15. Designing block copolymer architectures for targeted membrane performance

    KAUST Repository

    Dorin, Rachel Mika

    2014-01-01

    Using a combination of block copolymer self-assembly and non-solvent induced phase separation, isoporous ultrafiltration membranes were fabricated from four poly(isoprene-b-styrene-b-4-vinylpyridine) triblock terpolymers with similar block volume fractions but varying in total molar mass from 43 kg/mol to 115 kg/mol to systematically study the effect of polymer size on membrane structure. Small-angle X-ray scattering was used to probe terpolymer solution structure in the dope. All four triblocks displayed solution scattering patterns consistent with a body-centered cubic morphology. After membrane formation, structures were characterized using a combination of scanning electron microscopy and filtration performance tests. Membrane pore densities that ranged from 4.53 × 1014 to 1.48 × 1015 pores/m 2 were observed, which are the highest pore densities yet reported for membranes using self-assembly and non-solvent induced phase separation. Hydraulic permeabilities ranging from 24 to 850 L m-2 h-1 bar-1 and pore diameters ranging from 7 to 36 nm were determined from permeation and rejection experiments. Both the hydraulic permeability and pore size increased with increasing molar mass of the parent terpolymer. The combination of polymer characterization and membrane transport tests described here demonstrates the ability to rationally design macromolecular structures to target specific performance characteristics in block copolymer derived ultrafiltration membranes. © 2013 Elsevier Ltd.

  16. Nudging for health: on public policy and designing choice architecture.

    Science.gov (United States)

    Quigley, Muireann

    2013-01-01

    There have been recent policy moves aimed at encouraging individuals to lead healthier lives. The Cabinet Office has set up a 'nudge unit' with health as one of its priorities and behavioural approaches have started to be integrated into health-related domestic policy in a number of areas. Behavioural research has shown that that the way the environment is constructed can shape a person's choices within it. Thus, it is hoped that, by using insights from such research, people can be nudged towards making decisions which are better for their health. This article outlines how nudges can be conceived of as part of an expanding arsenal of health-affecting regulatory tools being used by the Government and addresses some concerns which have been expressed regarding behavioural research-driven regulation and policy. In particular, it makes the case that, regardless of new regulatory and policy strategies, we cannot escape the myriad of influences which surround us. As such, we can view our health-affecting decisions as already being in some sense shaped and constructed. Further, it argues we may in fact have reason to prefer sets of health-affecting options which have been intentionally designed by the state, rather than those that stem from other sources or result from random processes. Even so, in closing, this article draws attention to the largely unanswered questions about how behavioural research translates into policy and regulatory initiatives. PMID:24081425

    2004-01-01

    Full Text Available The paper discusses selected problems encountered in practical rule-based systems (RBS design and implementation. To solve them XTT, a new visual knowledge representation is introduced. Then a complete, integrated RBS design, implementation and analysis methodology is presented. This methodology is supported by a visual CASE tool called Mirella.The main goal is to move the design procedure to a more abstract, logical level, where knowledge specification is based on use of abstract rule representation. The design specification is automatically translated into Prolog code, so the designer can focus on logical specification of safety and reliability. On the other hand, system formal aspects are automatically verified on-line during the design, so that its verifiable characteristics are preserved.

  8. An Evaluation of Criteria-Based Assessment and Grading in Architecture Design

    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.

    NAREGI is a 5-year Japanese National Grid Project during 2003-2007, whose chief aim is to develop a set of grid middleware to serve as a basis for future e-Science. NAREGI also aims to lead the way in standardization of grid middleware, based on the OGSA architecture. Its super-scheduler is based on the proposed OGSA-EMS Architecture, in that it becomes the first working implementation that implements the documented component relationships within the OGSA-EMS architecture document v.1.0. Through the efforts and experience in the design and implementation, it has been confirmed that the documented OGSA-EMS architecture is quite feasible, but will require significant amount of refinement and speed improvements to finalize its detailed specifications. The super-scheduler also supports co-allocation across multiple sites to support automated execution of grid-based MPIs that execute across machines. Such a resource allocation requires sophisticated interactions between the OGSA-EMS components not covered in the current OGSA-EMS architecture, some of which are non-trivial. Overall, job scheduling with OGSA-EMS has proven to not only work, but also that its job allocation and execution time is within reasonable bounds.

This attrition partly pertains to the intricacy of designing and developing complex systems, destined to be used sporadically, in a fast-pace evolving technological paradigm. System evolvability is therefore key in the design process and constitutes the main motivation for...... this work. We introduce a smart-mobile and LoC-based system architecture designed for evolvability. By propagating LoC programmability, instrumentation, and control tools to the highlevel abstraction smart-mobile software layer, our architecture facilitates the realisation of new use-cases and the...... accommodation for incremental LoC-technology developments. We demonstrate these features with an implementation allowing the interfacing of LoCs embedding current- or impedance-based biosensors such as Silicon Nanowire Field Effect Transistors (SiNW-FETs) or electrochemical transducers.

    The Copernicus Trajectory Design and Optimization System represents an innovative and comprehensive approach to on-orbit mission design, trajectory analysis and optimization. Copernicus integrates state of the art algorithms in optimization, interactive visualization, spacecraft state propagation, and data input-output interfaces, allowing the analyst to design spacecraft missions to all possible Solar System destinations. All of these features are incorporated within a single architecture that can be used interactively via a comprehensive GUI interface, or passively via external interfaces that execute batch processes. This paper describes the Copernicus software architecture together with the challenges associated with its implementation. Additionally, future development and planned new capabilities are discussed. Key words: Copernicus, Spacecraft Trajectory Optimization Software.

    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].

    Computer architecture is transiting from the multicore era into the heterogeneous era in which heterogeneous architectures use on-chip networks to access shared resources and how a network is configured will likely have a significant impact on overall performance and power consumption. Recently, heterogeneous network on chip (NoC) has been proposed not only to achieve performance comparable to that of the NoCs with buffered routers but also to reduce buffer cost and energy consumption. However, heterogeneous NoC design for heterogeneous GPU-CPU architectures has not been studied in depth. This paper first evaluates the performance and power consumption of a variety of static hot-potato based heterogeneous NoCs with different buffered and bufferless router placements, which is helpful to explore the design space for heterogeneous GPU-CPU interconnection. Then it proposes Unidirectional Flow Control (UFC), a simple credit-based flow control mechanism for heterogeneous NoC in GPU-CPU architectures to control network congestion. UFC can guarantee that there are always unoccupied entries in buffered routers to receive flits coming from adjacent bufferless routers. Our evaluations show that when compared to hot-potato routing, UFC improves performance by an average of 14.1%with energy increased by an average of 5.3%only.

  1. Integration of Structural Knowledge in Design Studio Project: Assessment Study of Curriculum In Architecture Course in University Of Malaya

    Full Text Available Architectural education should advance in parallel with the industrial growth of building technology. Universities as producers of future architects have yet to develop curriculums for building technology to suit the growth of the building industry. This gap between education and industrial growth has been a topic of debate for many researchers who are concerned about architectural pedagogy. Architectural instruction further aggravated the problem whereby in most architectural schools worldwide, teaching is divided between the design studio, where the design projects are taught and lecture classes where the technical parts are taught. The latter should be integrated with design studio to enhance design levels. Students face difficulty integrating and applying the structural knowledge gained from structure classes into their design. One explanation for this deficiency is because the current architectural structure subject's content is borrowed from an engineering syllabus. This study will examine the course content, instruction styles and method of teaching structure subjects and will investigate the learning outcomes of design studio through students' performance and perception in integrating structural knowledge in their design projects. Respondents were students from Year 1 to Year 5 doing their Bachelor of Science in Architecture and Bachelor of Architecture degrees in University of Malaya. Semi-structured interviews were conducted with the design studio coordinators and structure lecturers. This study aims to find the ideal course content/method of teaching to facilitate more integration between structure and design studio.

  2. Distributed design tools: Mapping targeted design tools onto a Web-based distributed architecture for high-performance computing

    1999-11-30

    Design Tools use a Web-based Java interface to guide a product designer through the design-to-analysis cycle for a specific, well-constrained design problem. When these Design Tools are mapped onto a Web-based distributed architecture for high-performance computing, the result is a family of Distributed Design Tools (DDTs). The software components that enable this mapping consist of a Task Sequencer, a generic Script Execution Service, and the storage of both data and metadata in an active, object-oriented database called the Product Database Operator (PDO). The benefits of DDTs include improved security, reliability, scalability (in both problem size and computing hardware), robustness, and reusability. In addition, access to the PDO unlocks its wide range of services for distributed components, such as lookup and launch capability, persistent shared memory for communication between cooperating services, state management, event notification, and archival of design-to-analysis session data.

  3. Design, fabrication and properties of novel architectures made from carbon nanotubes and nano-porous materials

    Science.gov (United States)

    Kaur, Sumanjeet

    Nanomaterials like carbon nanotubes (CNT) have numerous potential applications due to their unique electrical, thermal and mechanical properties. Building macroscopic architectures using these nanocomponents requires new approaches for organization or assembly of these components. This can be achieved by using various techniques like capillary-induced compaction, template-assisted growth and other synthesis techniques. The vertically aligned multiwalled carbon nanotube arrays were grown using chemical vapor deposition (CVD). Evaporation of liquid from such vertically aligned nanotube arrays induces the assembly of nanotubes into cellular patterns. The role of substrate and orientation of the carbon nanotube array was investigated and analyzed to gain more control over the pattern formation that could help in designing new structures. Electrical measurements on the CNT patterns before and after capillary-induced compaction revealed that compaction results in four-fold increase in electrical conductivity, making them a potential candidate for vertical interconnects. A new method to fabricate a syringe with nanopores by using anodization technique was demonstrated. Experimental parameters were investigated to control the dimension and morphology of the nanopores in the syringe. Capillary force was used to infiltrate and replicate the complete 3D architecture into polymers. The usefulness of syringe as a biological sampler (DNA-RNA separation) was demonstrated. Layered structure of exfoliated mica was used as a substrate for growth of CNTs. This resulted in novel layered hybrid architecture of mica and carbon nanotube arrays. Mechanical properties of such architectures were investigated. Such architectures could be very useful as foams. These simple techniques can be used to assemble nanoscale components into well-defined macroscopic architectures and thus broaden the range of applications where their unique properties can be put into use.

  4. Heuristic rules analysis on the fuel cells design using greedy search

    International Nuclear Information System (INIS)

    This work approaches the study of one of the heuristic rules of fuel cells design for boiling water nuclear reactors. This rule requires that the minor uranium enrichment is placed in the corners of the fuel cell. Also the search greedy is applied for the fuel cells design where explicitly does not take in count this rule, allowing the possibility to place any uranium enrichment with the condition that it does not contain gadolinium. Results are shown in the quality of the obtained cell by search greedy when it considers the rule and when not. The cell quality is measured with the value of the power pick factor obtained, as well as of the neutrons multiplication factor in an infinite medium. Cells were analyzed with 1 and 2 gadolinium concentrations low operation conditions at 120% of the nominal power of the reactors of the nuclear power plant of Laguna Verde. The results show that not to consider the rule in cells with a single gadolinium concentration, it has as repercussion that the greedy search has a minor performance. On the other hand with cells of two gadolinium concentrations, the performance of the greedy search was better. (Author)

    Full Text Available The objective of this paper is to design a multi-agent system architecture for the Scrum methodology.Scrum is an iterative, incremental framework for software development which is flexible, adaptable andhighly productive. An agent is a system situated within and a part of an environment that senses theenvironment and acts on it, over time, in pursuit of its own agenda and so as to effect what it senses in thefuture (Franklin and Graesser, 1996. To our knowledge, this is first attempt to include software agents inthe Scrum framework. Furthermore, our design covers all the stages of software development. Alternativeapproaches were only restricted to the analysis and design phases. This Multi-Agent System (MASArchitecture for Scrum acts as a design blueprint and a baseline architecture that can be realised into aphysical implementation by using an appropriate agent development framework. The development of anexperimental prototype for the proposed MAS Architecture is in progress. It is expected that this tool willprovide support to the development team who will no longer be expected to report, update and managenon-core activities daily.

  9. Exploring the impact of mask making constraints on double patterning design rules

    2011-11-01

    In order to achieve an economical design-to-mask (DTM) development cycle in the low k1 domain, designers, lithographers, and mask makers needed to move away from many sequentially isolated developmental activities onto one collaborative environment managed by a computational lithography platform that integrates their respective ecosystems. 1,2 A successful development cycle used to be achievable by designers providing designs to lithographers, who then provided RET/OPC solutions to realize designs, but once k1 fell below a certain level, the lithographers could not provide solutions to realize some critical designs, which then required feedback to designers for further redesigns requiring further lithographic evaluation cycles. So collaboration and automations between lithographers and designers became necessary to reduce feedback loops and development cycle time. RET and design solutions also were impacted by mask making, and so mask maker's feedback on MRC and other constraints needed to be integrated for all three groups to achieve an economical DTM. As many lithographers attempted to print sub-80 nm pitches with 193 nm wavelength, it became necessary to use double patterning to achieve feature resolution. With the effective pitch doubling on each split layer, there could be significant increased design rule freedom for certain complex design situations. Using an integrated computational lithographic platform, one could find design space sweet spots that could further achieve optimal lithographic performance. In this paper, the optimization of design rules (DRD) for double pattern designs (~60 nm pitch) was explored with the mask maker's perspective. The experiment to be presented started with a 2x nm design set of clips. Each set of clips underwent size/width/space/pitch variations to generate a design space, and then each design space underwent SMO with an inverse lithography technology (ILT) engine using various mask MRC's and manhattan segmentations.

    2012-11-01

    A rapidly developing field is that of tailsitters, aircraft capable of transitioning between horizontal and vertical flight, a premise that supports a diverse range of applications. Tailsitters can effortlessly land and hover at will, yet can also move at high speed between destinations making them ideal in undertaking 'multiple missions to land at multiple destinations far apart'. This paper considers how the concept of twin helicopter rotor tailsitters, such as QinetiQ's Eye-OnTM, can be adapted for use in a Martian environment. The mission architecture and system requirements for both reusable and single-use tailsitters are considered and 12 disparate subsystems or fields (including propulsion, power and aerodynamics) are designed using a high-level systems approach. The resulting tailsitter is capable of covering 100km and 450km in reusable and single-use architectures respectively. A docking station is also designed utilising a four stage process for deployment of the tailsitter.

    2011-04-01

    Full Text Available This paper presents a technology-independent design and simulation of a modified architecture ofthe Carry-Save Adder. This architecture is shown to produce the result of the addition fast and byrequiring a minimum number of logic gates. Binary addition is carried out by a series of XOR,AND and Shift-left operations. These operations are terminated with a completion signalindicating that the result of the addition is obtained. Because the number of shift operationscarried out varies from 0 to n for n-bit addends, a behavioral model was developed in which allthe possible addends having 2- to 15-bits were applied. A mathematical model was deductedfrom the data and used to predict the average number of shift required for standard binarynumbers such as 32, 64 or 128-bits. 4-bit prototypes of this adder were designed and simulatedin both synchronous and asynchronous modes of operation.
