    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.

  2. An approach for modelling architectural design rules in UML and its application to embedded software

    OpenAIRE

    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

    Neural cryptography, a type of public key exchange protocol, is widely considered as an effective method for sharing a common secret key between two neural networks on public channels. How to design neural cryptography remains a great challenge. In this paper, in order to provide an approach to solve this challenge, a generalized network architecture and a significant heuristic rule are designed. The proposed generic framework is named as tree state classification machine (TSCM), which extends and unifies the existing structures, i.e., tree parity machine (TPM) and tree committee machine (TCM). Furthermore, we carefully study and find that the heuristic rule can improve the security of TSCM-based neural cryptography. Therefore, TSCM and the heuristic rule can guide us to designing a great deal of effective neural cryptography candidates, in which it is possible to achieve the more secure instances. Significantly, in the light of TSCM and the heuristic rule, we further expound that our designed neural cryptography outperforms TPM (the most secure model at present) on security. Finally, a series of numerical simulation experiments are provided to verify validity and applicability of our results.

    2011-05-01

    In this paper I present a new perspective of the birth and evolution of Planetary Systems. This new perspective presents an all encompassing and self consistent Paradigm of the birth and evolution of the solar systems. In doing so it redefines astronomy and rewrites astronomical principles. Kepler and Newton defined a stable and non-evolving elliptical orbits. While this perspective defines a collapsing or expanding spiral orbit of planets except for Brown Dwarfs. Brown Dwarfs are significant fraction of the central star. Hence they rapidly evolve from non-Keplerian state to the end point which is a Keplerian state where it is in stable elliptical orbits. On the basis of the Lunar Laser Ranging Data released by NASA on the Silver Jubilee Celebration of Man's Landing on Moon on 21st July 1969-1994, theoretical formulation of Earth-Moon tidal interaction was carried out and Planetary Satellite Dynamics was established. It was found that this mathematical analysis could as well be applied to Star and Planets system and since every star could potentially contain an extra-solar system, hence we have a large ensemble of exo-planets to test our new perspective on the birth and evolution of solar systems. Till date 403 exo-planets have been discovered in 390 extra-solar systems by radial velocity method, by transiting planet method, by gravitational lensing method, by direct imaging method and by timing method. I have taken 12 single planet systems, four Brown Dwarf - Star systems and two Brown Dwarf pairs. Following architectural design rules are corroborated through this study of exo-planets. All planets are born at inner Clarke's Orbit what we refer to as inner geo-synchronous orbit in case of Earth-Moon System. The inner Clarke's Orbit is an orbit of unstable equilibrium. By any perturbative force such as cosmic particles or radiation pressure, the planet gets tipped long of aG1 or short of aG1. Here aG1 is inner Clarke's Orbit. If planet is long of aG1 then it is said

    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...... an improved thermal indoor environment in south-oriented rooms and will ensure a better daylight level especially in north-oriented rooms. We also show that the optimal window size is influenced by thermal zone configuration and that there is a need for models in which a difference is made between zones...

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

    Directory of Open Access Journals (Sweden)

    Kerckhove Wannes

    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.

  16. 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.

    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.

    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.

    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

    Full Text Available Creative activity is one of the most significant parts of architectural education. In the architectural curriculum organisation ‘design studio’ is the unique and preeminent subject. Freshman students encounter ‘design’ first in basic design course, before they know what designing incorporates.

    2009-11-01

    Under the project SENSOR-IA which has had financial funding from the Order of Incentives to the Regional Technology Centers of the Counsil of Innovation, Science and Enterprise of Andalusia, an architecture for the optimization of a machining process in real time through rule-based expert system has been developed. The architecture consists of an acquisition system and sensor data processing engine (SATD) from an expert system (SE) rule-based which communicates with the SATD. The SE has been designed as an inference engine with an algorithm for effective action, using a modus ponens rule model of goal-oriented rules.The pilot test demonstrated that it is possible to govern in real time the machining process based on rules contained in a SE. The tests have been done with approximated rules. Future work includes an exhaustive collection of data with different tool materials and geometries in a database to extract more precise rules.

    Hsu, Chia-Hsin; Chen, Chien-Kuo; Hwang, Ming-Jing

    2013-08-23

    Protein domain architectures (PDAs), in which single domains are linked to form multiple-domain proteins, are a major molecular form used by evolution for the diversification of protein functions. However, the design principles of PDAs remain largely uninvestigated. In this study, we constructed networks to connect domain architectures that had grown out from the same single domain for every single domain in the Pfam-A database and found that there are three main distinctive types of these networks, which suggests that evolution can exploit PDAs in three different ways. Further analysis showed that these three different types of PDA networks are each adopted by different types of protein domains, although many networks exhibit the characteristics of more than one of the three types. Our results shed light on nature's blueprint for protein architecture and provide a framework for understanding architectural design from a network perspective.

    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

  17. Do Rules and Patterns Affect Design Maintainability?

    Institute of Scientific and Technical Information of China (English)

    Javier Garzás; Félix García; Mario Piattini

    2009-01-01

    At the present time, best rules and patterns have reached a zenith in popularity and diffusion, thanks to the software community's efforts to discover, classify and spread knowledge concerning all types of rules and patterns. Rules and patterns are useful elements, but many features remain to be studied if we wish to apply them in a rational manner.The improvement in quality that rules and patterns can inject into design is a key issue to be analyzed, so a complete body of empirical knowledge dealing with this is therefore necessary. This paper tackles the question of whether design rules and patterns can help to improve the extent to which designs are easy to understand and modify. An empirical study, composed of one experiment and a replica, was conducted with the aim of validating our conjecture. The results suggest that the use of rules and patterns affect the understandability and modifiability of the design, as the diagrams with rules and patterns are more difficult to understand than non-rule/pattern versions and more effort is required to carry out modifications to designs with rules and patterns.

    1995-05-01

    Successful cosmetic dental treatment is both functional and aesthetic. It requires evaluation of a patient's expectations, diagnosis of pre-existing problems and careful planning of treatment to eliminate or control the causes of existing conditions. The use of mounted diagnostic casts and a diagnostic wax-up allows visualization of the expected result. Provisional restorations offer a "dress rehearsal" to preview functional and aesthetic results before completion of the final restorations. The term "smile architecture" is used to describe the process that guides a patient and dentist from initial complaint through to final case acceptance.

    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.

    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.

    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.

    Full Text Available Architectural redevelopment and the revival of the construction sector are conditional on the incentivisation and bolstering of innovation processes. Thus the partial declensions that have been attached to these processes over the last few years have seen research and experimentation being tailored to the spectacularisation of shapes or the hidden performance optimisation of materials and components. Genuine improvement in the quality of architecture and its construction in this day and age depends on the abilities of designers to adopt the entire life cycle of buildings as a reference framework and on the willingness of all those working in the construction supply chain to activate virtuous cooperation.

    Iyad Alazzam

    2016-08-01

    Full Text Available SDN as a network architecture emerged on top of existing technologies and knowledge. Through defining the controller as a software program, SDN made a strong connection between networking and software engineering. Traditionally, network programs were vendor specific and embedded in hardware switches and routers. SDN focuses on isolation between control and forwarding or data planes. However, in the complete SDN network, there are many other areas (i.e. CPU, memory, hardware, bandwidth and software. In this paper, we propose extending SDN architecture and propose isolation layers with the goal of improving the overall network design. Such flexible architecture can support future evolution and changes without the need to significantly change original components or modules.

    Moulton, Christine L.; Krzywicki, Alan T.; Hepp, Jared J.; Harrell, John; Kogut, Michael

    2015-05-01

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

  14. 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.

    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.

  1. Understanding the Lunar System Architecture Design Space

    Arney, Dale C.; Wilhite, Alan W.; Reeves, David M.

    2013-01-01

    Based on the flexible path strategy and the desire of the international community, the lunar surface remains a destination for future human exploration. This paper explores options within the lunar system architecture design space, identifying performance requirements placed on the propulsive system that performs Earth departure within that architecture based on existing and/or near-term capabilities. The lander crew module and ascent stage propellant mass fraction are primary drivers for feasibility in multiple lander configurations. As the aggregation location moves further out of the lunar gravity well, the lunar lander is required to perform larger burns, increasing the sensitivity to these two factors. Adding an orbit transfer stage to a two-stage lunar lander and using a large storable stage for braking with a one-stage lunar lander enable higher aggregation locations than Low Lunar Orbit. Finally, while using larger vehicles enables a larger feasible design space, there are still feasible scenarios that use three launches of smaller vehicles.

    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...

    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.

  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%.

    SpicA FAR infrared Instrument, SAFARI, is one of the instruments planned for the SPICA mission. The SPICA mission is the next great leap forward in space-based far-infrared astronomy and will study the evolution of galaxies, stars and planetary systems. SPICA will utilize a deeply cooled 2.5m-class telescope, provided by European industry, to realize zodiacal background limited performance, and high spatial resolution. The instrument SAFARI is a cryogenic grating-based point source spectrometer working in the wavelength domain 34 to 230 μm, providing spectral resolving power from 300 to at least 2000. The instrument shall provide low and high resolution spectroscopy in four spectral bands. Low Resolution mode is the native instrument mode, while the high Resolution mode is achieved by means of a Martin-Pupplet interferometer. The optical system is all-reflective and consists of three main modules; an input optics module, followed by the Band and Mode Distributing Optics and the grating Modules. The instrument utilizes Nyquist sampled filled linear arrays of very sensitive TES detectors. The work presented in this paper describes the optical design architecture and design concept compatible with the current instrument performance and volume design drivers.

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.

    2014-01-01

    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.

    2009-01-01

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

    2012-01-01

    As Moore’s law continues to unfold, two important trends have recently emerged. First, the growth of chip capacity is translated into a corresponding increase of number of cores. Second, the parallalization of the computation and 3D integration technologies lead to distributed memory architectures. This book provides a current snapshot of industrial and academic research, conducted as part of the European FP7 MOSART project, addressing urgent challenges in many-core architectures and application mapping.  It addresses the architectural design of many core chips, memory and data management, power management, design and programming methodologies. It also describes how new techniques have been applied in various industrial case studies. Describes trends towards distributed memory architectures and distributed power management; Integrates Network on Chip with distributed, shared memory architectures; Demonstrates novel design methodologies and frameworks for multi-core design space exploration; Shows how midll...

    Architectures depict design principles, paradigms that can be understood by all, allow thinking on a higher plane and avoiding low-level mistakes. They provide means for ensuring correctness by construction by enforcing global properties characterizing the coordination between components. An architecture can be considered as an operator A that, applied to a set of components B, builds a composite component A(B) meeting a characteristic property P. A theory of architectures must address sever...

    Full Text Available Stemming is the process of clipping off the affixes from the input word to obtain the respective root word, but it is not necessary that stemming pr ovide us the genuine and meaningful root word. To overcome this problem we come up with a so lution- Lemmatizer. It is the process by which we crave out the lemma from the given word an d can also add additional rules to make the clipped word a proper stem. In this paper we ha ve created an inflectional lemmatizer which generates the rules for extracting the suffixes and also added rules for generating a proper meaningful root word

  16. Expanding color design methods for architecture and allied disciplines

    Science.gov (United States)

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

    2013-03-01

    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.

    2008-01-01

    Domain specific software architecture aims at software reuse through construction of domain architecture reference model. The constructed reference model presents a set of individual components and their interaction points. When starting on a new large software project, the design engineer starts with pre-constructed model, which can be easily browsed and picks up opportunities of use in the new solution design. This report discusses application of domain reference design methods by deriving domain specific reference architecture for a product ordering system in a design center. The product in this case is instock and special order blinds from different manufacturers in a large supply store. The development of mature domain specific reference software architecture for this domain is not the objective of this report. However, this report would like to capture the method used in one such process and that is the primary concern of this report. This report lists subjective details of such a process applied to the...

    Active bending introduces a new level of integration into the design of architectural structures, and opens up new complexities for the architectural design process. In particular, the introduction of material variation reconfigures the design space. Through the precise specification...... of their stiffness, it is possible to control and pre-calibrate the bending behaviour of a composite element. This material capacity challenges architecture’s existing methods for design, specification and prediction. In this paper, we demonstrate how architects might connect the designed nature of composites...... with the design of bending-active structures, through computational strategies. We report three built structures that develop architecturally oriented design methods for bending-active systems using composite materials. These projects demonstrate the application and limits of the introduction of advanced...

    CAO Donggang; MEI Hong; ZHOU Minghui

    2007-01-01

    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.

  15. Designing flexible engineering systems utilizing embedded architecture options

    Science.gov (United States)

    Pierce, Jeff G.

    This dissertation develops and applies an integrated framework for embedding flexibility in an engineered system architecture. Systems are constantly faced with unpredictability in the operational environment, threats from competing systems, obsolescence of technology, and general uncertainty in future system demands. Current systems engineering and risk management practices have focused almost exclusively on mitigating or preventing the negative consequences of uncertainty. This research recognizes that high uncertainty also presents an opportunity to design systems that can flexibly respond to changing requirements and capture additional value throughout the design life. There does not exist however a formalized approach to designing appropriately flexible systems. This research develops a three stage integrated flexibility framework based on the concept of architecture options embedded in the system design. Stage One defines an eight step systems engineering process to identify candidate architecture options. This process encapsulates the operational uncertainty though scenario development, traces new functional requirements to the affected design variables, and clusters the variables most sensitive to change. The resulting clusters can generate insight into the most promising regions in the architecture to embed flexibility in the form of architecture options. Stage Two develops a quantitative option valuation technique, grounded in real options theory, which is able to value embedded architecture options that exhibit variable expiration behavior. Stage Three proposes a portfolio optimization algorithm, for both discrete and continuous options, to select the optimal subset of architecture options, subject to budget and risk constraints. Finally, the feasibility, extensibility and limitations of the framework are assessed by its application to a reconnaissance satellite system development problem.

    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.

  17. 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.

    Office buildings with important administrative functions can produce high energy demands for lighting, cooling and heating. However, appropriate architectural design can achieve significant energy savings and improve environmental conditions, without sacrificing architectural quality. Intense solar radiation and high temperature swings in dry continental climates favour deep plan offices, though natural daylight requires limited depth. This paper presents a case study of a large administrative complex project for the Justice Palace, Neuquen Province, in the cold windy sem-desert climate in the Northern Patagonia Region of Argentina, demonstrating the relevance of specialised advisory services in the architectural field.

    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...

  4. Software Engineering in Practice: Design and Architectures of FLOSS Systems

    Science.gov (United States)

    Capiluppi, Andrea; Knowles, Thomas

    Free/Libre/Open Source Software (FLOSS) practitioners and developers are typically also users of their own systems: as a result, traditional software engineering (SE) processes (e.g., the requirements and design phases), take less time to articulate and negotiate among FLOSS developers. Design and requirements are kept more as informal knowledge, rather than formally described and assessed. This paper attempts to recover the SE concepts of software design and architectures from three FLOSS case studies, sharing the same application domain (i.e., Instant Messaging). Its first objective is to determine whether a common architecture emerges from the three systems, which can be used as shared knowledge for future applications. The second objective is to determine whether these architectures evolve or decay during the evolution of these systems. The results of this study are encouraging: albeit no explicit effort was done by FLOSS developers to define a high-level view of the architecture, a common shared architecture could be distilled for the Instant Messaging application domain. It was also found that, for two of the three systems, the architecture becomes better organised, and the components better specified, as long as the system evolves in time.

  5. Designing Dependable Service Oriented Web Services Security Architectures Solutions

    Directory of Open Access Journals (Sweden)

    M.Upendra Kumar

    2010-04-01

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

    Full Text Available 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.

  13. Specification, Design, and Analysis of Advanced HUMS Architectures

    Mukkamala, Ravi

    2004-01-01

    During the two-year project period, we have worked on several aspects of domain-specific architectures for HUMS. In particular, we looked at using scenario-based approach for the design and designed a language for describing such architectures. The language is now being used in all aspects of our HUMS design. In particular, we have made contributions in the following areas. 1) We have employed scenarios in the development of HUMS in three main areas. They are: (a) To improve reusability by using scenarios as a library indexing tool and as a domain analysis tool; (b) To improve maintainability by recording design rationales from two perspectives - problem domain and solution domain; (c) To evaluate the software architecture. 2) We have defined a new architectural language called HADL or HUMS Architectural Definition Language. It is a customized version of xArch/xADL. It is based on XML and, hence, is easily portable from domain to domain, application to application, and machine to machine. Specifications written in HADL can be easily read and parsed using the currently available XML parsers. Thus, there is no need to develop a plethora of software to support HADL. 3) We have developed an automated design process that involves two main techniques: (a) Selection of solutions from a large space of designs; (b) Synthesis of designs. However, the automation process is not an absolute Artificial Intelligence (AI) approach though it uses a knowledge-based system that epitomizes a specific HUMS domain. The process uses a database of solutions as an aid to solve the problems rather than creating a new design in the literal sense. Since searching is adopted as the main technique, the challenges involved are: (a) To minimize the effort in searching the database where a very large number of possibilities exist; (b) To develop representations that could conveniently allow us to depict design knowledge evolved over many years; (c) To capture the required information that aid the

  14. Performance-oriented Architecture: Towards a Biological Paradigm for Architectural Design and the Built Environment

    Directory of Open Access Journals (Sweden)

    Michael Ulrich Hensel

    2010-07-01

    Full Text Available This paper introduces and elaborates a specific approach to architectural design entitled ‘performance-oriented architecture’ based on a redefinition of the concept of ‘performance’ in relation to the discipline of architecture and set within a biological paradigm. The concept of ‘performance’ evolved out of a series of intellectual efforts that had broad consequences, brining about a paradigm shift in the humanities referred to as the ‘performative turn’. These efforts commenced in the 1940s and 1950s and had significant impact also on the sciences, deriving what is referred to as the ‘performative idiom’. Here the question is raised as to what ‘performance’ in the context of architecture may entail. The approach introduced con­trasts previous ones that focused either on questions of representation and meaning in architecture, or, alternatively that have treated performance as synonymous to function placed in the context of post-design functional optimisation. Contrasting these previous efforts performance is here reformulated as a driving concept for design that helps re-con­solidate form and function into a synergetic relation with the dynamics of natural, cultural and social environments, and in so doing, locate performative capacity - ‘ active agency’ - in the spatial and material organisation of architecture, in the human subject and the environ­ment through the dynamic interaction between these four domains. In pursuing this approach the potential of a close disciplinary affiliation between architecture and biology is examined, so as to locate a suitable paradigm for performance in the discipline of biology and its var­ious sub-disciplines, in its various foci and modes of inquiry, and, moreover, in biological syst­ems.

  19. ELISA, a demonstrator environment for information systems architecture design

    Science.gov (United States)

    Panem, Chantal

    1994-01-01

    This paper describes an approach of reusability of software engineering technology in the area of ground space system design. System engineers have lots of needs similar to software developers: sharing of a common data base, capitalization of knowledge, definition of a common design process, communication between different technical domains. Moreover system designers need to simulate dynamically their system as early as possible. Software development environments, methods and tools now become operational and widely used. Their architecture is based on a unique object base, a set of common management services and they host a family of tools for each life cycle activity. In late '92, CNES decided to develop a demonstrative software environment supporting some system activities. The design of ground space data processing systems was chosen as the application domain. ELISA (Integrated Software Environment for Architectures Specification) was specified as a 'demonstrator', i.e. a sufficient basis for demonstrations, evaluation and future operational enhancements. A process with three phases was implemented: system requirements definition, design of system architectures models, and selection of physical architectures. Each phase is composed of several activities that can be performed in parallel, with the provision of Commercial Off the Shelves Tools. ELISA has been delivered to CNES in January 94, currently used for demonstrations and evaluations on real projects (e.g. SPOT4 Satellite Control Center). It is on the way of new evolutions.

    Rafe, Vahid; Hajvali, Masoumeh

    2013-04-01

    Nowadays, the Pervasive Healthcare (PH) systems are considered as an important research area. These systems have a dynamic structure and configuration. Therefore, an appropriate method for designing such systems is necessary. The Publish/Subscribe Architecture (pub/sub) is one of the convenient architectures to support such systems. PH systems are safety critical; hence, errors can bring disastrous results. To prevent such problems, a powerful analytical tool is required. So using a proper formal language like graph transformation systems for developing of these systems seems necessary. But even if software engineers use such high level methodologies, errors may occur in the system under design. Hence, it should be investigated automatically and formally that whether this model of system satisfies all their requirements or not. In this paper, a dynamic architectural style for developing PH systems is presented. Then, the behavior of these systems is modeled and evaluated using GROOVE toolset. The results of the analysis show its high reliability.

    This paper investigates how architectural school competition juries assess Universal Design. The method used is a case study of 18 recent architectural school competitions in Norway. The results show that most competition briefs ask for Universal Designed buildings. In 8 of the 18 cases, Universal Design is mentioned as an assessment criterion. In 11 of the 18 cases, Universal Design is commented on by the juries in the jury reports, but only in 3 of the cases, do the juries assess this aspect consistently on every competition project. The overall impression is that some amount of uncertainty looms concerning how Universal Design should be assessed in the competition stage. Based on the findings, future juries should concentrate on orientation and overview prior to technicalities and details.

    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.

    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.

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

    Full Text Available 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.

    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

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

  8. 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...

    2012-01-01

    Alterations made in the architectural design can be considered as a continuous process, from its conception to the moment a built environment is already in use. This article focuses on the "moving phase", which is the initial moment of the environment occupation and the start-up of services. It aims to show that the continuity of ergonomics interventions during the "moving phase" or start up may reveal the built environment inadequacies; clearly showing needs not met by the design and allowing making instant decisions to solve non-foreseen problems. The results have revealed some lessons experienced by users during a critical stage not usually included in the design process.

    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.

    2007-02-01

    The paper discusses concepts about the role of architecture in the design of space habitats and the development of a general evaluation criteria of architectural design contribution. Besides the existing feasibility studies, the general requisites, the development studies, and the critical design review which are mainly based on the experience of human space missions and the standards of the NASA-STD-3000 manual and which analyze and evaluate the relation between man and environment and between man and machine mainly in its functionality, there is very few material about design of comfort and wellbeing of man in space habitat. Architecture for space habitat means the design of an artificial environment with much comfort in an "atmosphere" of wellbeing. These are mainly psychological effects of human factors which are very important in the case of a long time space mission. How can the degree of comfort and "wellbeing atmosphere" in an artificial environment be measured? How can the quality of the architectural contribution in space design be quantified? Definition of a criteria catalogue to reach a larger objectivity in architectural design evaluation. Definition of constant parameters as a result of project necessities to quantify the quality of the design. Architectural design analysis due the application and verification within the parameters and consequently overlapping and evaluating results. Interdisciplinary work between architects, astronautics, engineers, psychologists, etc. All the disciplines needed for planning a high quality habitat for humans in space. Analysis of the principles of well designed artificial environment. Good quality design for space architecture is the result of the interaction and interrelation between many different project necessities (technological, environmental, human factors, transportation, costs, etc.). Each of this necessities is interrelated in the design project and cannot be evaluated on its own. Therefore, the design

    2016-01-01

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

    Virtual memory is an imaginary main memory with a very large capacity which the programmer has at his disposal. It greatly contributes to the solution of the dynamic storage allocation problem. The architectural design of a virtual memory is presented which implements by hardware the idea of queuing and scheduling the page requests to a paging drum in such a way that the access of the paging drum is increased many times. With the design, an increase of up to 16 times in page transfer rate is achievable when the virtual memory is heavily loaded. This in turn makes feasible a great increase in the system throughput.

    Lee, Kyu-Yeul; Ku, Namkug; Cha, Ju-Hwan

    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.

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

    Grangaard, Sidse; Frandsen, Anne Kathrine

    2016-01-01

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

    2015-04-01

    Burgeoning interest in supracolloidal assembly has reached the point at which the field can seek so-called intelligent design rather than solely rely on evolution. Emphasizing Janus and triblock particles, this review presents a progress report on formulating design rules for the assembly of interesting structures. We discuss how to design building blocks, bearing in mind that patchy particles embody not just geometric shape but also chemical shape, that chemical shape determines particle-particle interactions, and that the assembly process can be designed to proceed in hierarchical stages. Remarks are included about the potential of kinetic and nonequilibrium control, as well as the potential for the augmented use of soft building blocks. Whereas the reverse design problem, in which arbitrarily selected structures can be designed from the bottom up, still stands as a grand challenge, the field has reached the point of understanding necessary, although not always sufficient, conditions.

    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.

    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...

    2014-01-01

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

    2014-01-01

    Model-based design of biological parts is a critical goal of synthetic biology, especially for eukaryotes. Here we demonstrate that nucleosome architecture can have a role in defining yeast promoter activity and utilize a computationally-guided approach that can enable both the redesign of endogenous promoter sequences and the de novo design of synthetic promoters. Initially, we use our approach to reprogram native promoters for increased expression and evaluate their performance in various genetic contexts. Increases in expression ranging from 1.5- to nearly 6-fold in a plasmid-based system and up to 16-fold in a genomic context were obtained. Next, we demonstrate that, in a single design cycle, it is possible to create functional, purely synthetic yeast promoters that achieve substantial expression levels (within the top sixth percentile among native yeast promoters). In doing so, this work establishes a unique DNA-level specification of promoter activity and demonstrates predictive design of synthetic parts. PMID:24862902

    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

  17. MODIFIED MICROPIPLINE ARCHITECTURE FOR SYNTHESIZABLE ASYNCHRONOUS FIR FILTER DESIGN

    Directory of Open Access Journals (Sweden)

    Basel Halak

    2016-02-01

    Full Text Available The use of asynchronous design approaches to construct digital signal processing (DSP systems is a rapidly growing research area driven by a wide range of emerging energy constrained applications such as wireless sensor network, portable medical devices and brain implants. The asynchronous design techniques allow the construction of systems which are samples driven, which means they only dissipate dynamic energy when there processing data and idle otherwise. This inherent advantage of asynchronous design over conventional synchronous circuits allows them to be energy efficient. However the implementation flow of asynchronous systems is still difficult due to its lack of compatibility with industrystandard synchronous design tools and modelling languages. This paper devises a novel asynchronous design for a finite impulse response (FIR filter, an essential building block of DSP systems, which is synthesizable and suitable for implementation using conventional synchronous systems design flow and tools. The proposed design is based on a modified version of the micropipline architecture and it is constructed using four phase bundled data protocol. A hardware prototype of the proposed filter has been developed on an FPGA, and systematically verified. The results prove correct functionality of the novel design and a superior performance compared to a synchronous FIR implementation. The findings of this work will allow a wider adoption of asynchronous circuits by DSP designers to harness their energy and performance benefits.

    This document reviews the Design Reference Architecture (DRA) for human exploration of Mars. The DRA represents the current best strategy for human missions. The DRA is not a formal plan, but provides a vision and context to tie current systems and technology developments to potential missions to Mars, and it also serves as a benchmark against which alternative architectures can be measured. The document also reviews the objectives and products of the 2007 study that was to update NASA's human Mars mission reference architecture, assess strategic linkages between lunar and Mars strategies, develop an understanding of methods for reducing cost/risk of human missions through investment in research, technology development and synergy with other exploration plans. There is also a review of the process by which the DRA will continue to be refined. The unique capacities of human exploration is reviewed. The possible goals and objectives of the first three human missions are presented, along with the recommendation that the mission involve a long stay visiting multiple sites.The deployment strategy is outlined and diagrammed including the pre-deployment of the many of the material requirements, and a six crew travel to Mars on a six month trajectory. The predeployment and the Orion crew vehicle are shown. The ground operations requirements are also explained. Also the use of resources found on the surface of Mars is postulated. The Mars surface exploration strategy is reviewed, including the planetary protection processes that are planned. Finally a listing of the key decisions and tenets is posed.

    Full Text Available A generic nanoscale computing model is presented in this paper. The model consists of a collection of fully interconnected nanoscale computing modules, where each module is a cube of cells made out of quantum dots, spins, or molecules. The cells dynamically switch between two states by quantum interactions among their neighbors in all three dimensions. This paper includes a brief introduction to the field of nanotechnology from a computing point of view and presents a set of preliminary architectural designs for fabricating the nanoscale model studied.

    The article analyzes the relationship of function and decorated forms in architecture and design of different countries and times. Interaction function and decorated form predetermined internal logic of the development of architecture and arts and crafts. The history of the relationship functions and form also shows the impact on the architecture and design of certain socio-economic factors and the corresponding aesthetic views.

  3. 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.

    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.

  6. 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.

    Considered both a stepping-stone to deep space and a key to unlocking the mysteries of planetary formation, the Moon offers a unique opportunity for scientific study. Robotic precursor missions are being developed to improve technology and enable new approaches to exploration. Robots, lunar landers, and satellites play significant roles in advancing science and technologies, offering close range and in-situ observations. Science and exploration data gathered from these nodes and a lunar science satellite is intended to support future human expeditions and facilitate future utilization of lunar resources. To attain a global view of lunar science, the nodes will be distributed over the lunar surface, including locations on the far side of the Moon. Given that nodes on the lunar far side do not have direct line-of-sight for Earth communications, the planned presence of such nodes creates the need for a lunar communications relay satellite. Since the communications relay capability would only be required for a small portion of the satellite s orbit, it may be possible to include communication relay components on a science spacecraft. Furthermore, an integrated satellite has the potential to reduce lunar surface mission costs. A SCience Hybrid Orbiter and Lunar Relay (SCHOLR) is proposed to accomplish scientific goals while also supporting the communications needs of landers on the far side of the Moon. User needs and design drivers for the system were derived from the anticipated needs of future robotic and lander missions. Based on these drivers and user requirements, accommodations for communications payload aboard a science spacecraft were developed. A team of interns identified and compared possible SCHOLR architectures. The final SCHOLR architecture was analyzed in terms of orbiter lifetime, lunar surface coverage, size, mass, power, and communications data rates. This paper presents the driving requirements, operational concept, and architecture views for SCHOLR

    A principal challenge for reducing the cost for designing complex systems-on-chip is to pursue more generic systems for a broad range of products. For this purpose, we explore three new architectural concepts for state-of-art video applications. First, we discuss a reusable scalable hardware architecture employing a hierarchical communication network fitting with the natural hierarchy of the application. In a case study, we show that MPEG streaming in DTV occurs at high level, while subsystems communicate at lower levels. The second concept is a software design that scales over a number of processors to enable reuse over a range of VLSI process technologies. We explore this via an H.264 decoder implementation scaling nearly linearly over up to eight processors by applying data partitioning. The third topic is resource-scalability, which is required to satisfy realtime constraints in a system with a high amount of shared resources. An example complexity-scalable MPEG-2 coder scales the required cycle budget with a factor of three, in parallel with a smooth degradation of quality.

    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.

    To teach sustainable architecture is an ongoing process of establishing a frame where the student’s creativity can be challenged by dealing with actual demands on the anthropogenic scene. To use Urban Mining as a driver has been one of the most challenging teaching approaches since many years....... This approach involves a complex journey from investigating and harvesting local resources to gaining insight into metabolism and finally to design a project of diversity. The methodology used was based on industrial ecology. By realizing local resources and their potentials the students acquired knowledge...... of available materials, and components and as well as their upgrading versus downscaling. The design process explored ways of interconnecting the mined resources and to establish businesses based on this interconnections, producing economic value and social identity for the locals.

  18. Design Patterns For Successful Service Oriented Architecture Implementation

    Directory of Open Access Journals (Sweden)

    G. M. Tere

    2010-01-01

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

    Ahamed, Syed V; 10.5121/ijcnc.2010.2602

    2011-01-01

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

    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

    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 ...

  6. 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

  8. Designing Indoor Climate. A Thesis on the Integration of Indoor Climate Analysis in Architectural Design

    Energy Technology Data Exchange (ETDEWEB)

    Den Hartog, J.P.

    2003-12-01

    In contemporary architecture education, indoor climate and building installations suffer from a lack of popularity. Students of architecture, filled with great expectations and awe for the famous designers of the 20th century, find inspiration in examples such as Le Corbusier's Villa Savoy, Lloyd Wright's falling water or the Rietveld's Schroder house. Recognizable as this may be, great aesthetics constitute only a small part of creating architecture. The process of designing and constructing buildings comprises the involvement of a multitude of skills such as creating clear functional layouts, designing solid structures and taking care of healthy indoor climates. Most textbooks and magazines contemporary architecture do not cover the less attractive aspects of the indoor climate such as heating, ventilation and cooling unless these services form an important part of the buildings aesthetic identity. Recent examples regarding the integration of second skin facades and natural ventilation in indoor climate, sometimes fail to convince as a result of the lack of thorough evaluations and detailed information.

    The planet Mars has become the focus of an intensive series of missions that span decades of time, a wide array of international agencies and an evolution from robotics to humans. The number of missions to Mars at any one time, and over a period of time, is unprecedented in the annals of space exploration. To meet the operational needs of this exploratory fleet will require the implementation of new architectural concepts for communications and navigation. To this end, NASA's Jet Propulsion Laboratory has begun to define and develop a Mars communications and navigation orbital infrastructure. This architecture will make extensive use of assets at Mars, as well as use of traditional Earth-based assets, such as the Deep Space Network, DSN. Indeed, the total system can be thought of as an extension of DSN nodes and services to the Mars in-situ region. The concept has been likened to the beginnings of an interplanetary Internet that will bring the exploration of Mars right into our living rooms. The paper will begin with a high-level overview of the concept for the Mars communications and navigation infrastructure. Next, the mission requirements will be presented. These will include the relatively near-term needs of robotic landers, rovers, ascent vehicles, balloons, airplanes, and possibly orbiting, arriving and departing spacecraft. Requirements envisioned for the human exploration of Mars will also be described. The important Mars orbit design trades on telecommunications and navigation capabilities will be summarized, and the baseline infrastructure will be described. A roadmap of NASA's plan to evolve this infrastructure over time will be shown. Finally, launch considerations and delivery to Mars will be briefly treated.

    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.

    2013-08-21

    Coordination polymers (CPs) have large degrees of freedom in framework compositions and in the structures and environment of the inner pores. This review focuses on the recent significant progress achieved by controlling these degrees of freedom. Two breakthroughs are reviewed for constructing sophisticated structures of CP frameworks, especially in dimensional crossover regions. The first is the synthesis of quasi one-dimensional halogen-bridged coordinative tubes by applying state-of-the-art techniques of coordination chemistry. The electronic state of the coordinative tube was studied by structural, spectroscopic and theoretical methods and found to be distinct from conventional one-dimensional systems. The second breakthrough is the achievement of a quasi-two-dimensional architecture by combining Langmuir-Blodgett and layer-by-layer methods. Two-dimensional LB CP films were prepared on liquid; the films were stacked layer by layer, and a crystalline quasi-two-dimensional structure was constructed. This review also covers the design of the environment of the inner pore, where hydrogen bond networks with various acidic sites were modified. By appropriate design of the hydrogen bond network, proton-conductive CPs are invented, which are summarized in this review. Types of proton donor sites are discussed and classified, and superprotonic conductive CPs were achieved in these investigations. These results will provide new strategies for constructing functional materials for smart 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. 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.

  16. 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.

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

    Science.gov (United States)

    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. Embodiment and enculturation: the future of architectural design.

    Science.gov (United States)

    Mallgrave, Harry F

    2015-01-01

    A half-century ago the Dutch architect Aldo van Eyck encouraged designers to think about "space and time" not as abstractions in themselves but rather as cultural events better approached through the medium of "place and occasion." Van Eyck made this point on the basis of his own travels and through his extensive readings in cultural anthropology, and his prescience is only now acquiring the credibility that it deserves through the work of a multitude of interdisciplinary researchers. Phenomenologists argue that we are embodied organisms-acting-within-environments, and these inhabiting abodes are constructed of both material and cultural dimensions. We are thus preeminently social in our range of self-consciousness, and intensely ceremonial in every facet of our being. Evolutionary psychologists and anthropologists are currently locating the origin and development of our most basic social behaviors far in our pre-human past; neuroscientists are today modeling our social circuits in the deepest reaches of our brains. Architecture would gain much from an updated cultural theory grounded in these new models of human existence.

    Popular music plays an substantial role in most people’s life. The demand and financial revenue of Rock and pop concerts is large and still increasing. Though 80% of the music turnover is done in Rock and Pop Music, books assess only Classical concert and opera houses. However, the requirements for pop music halls are different from classical Music and opera houses. This book closes this gap including the following features: In part one, the book A. Gives a objective methodology to assess Rock and Pop Music Venues B. Shows essential construction details and choices of building materials in the design of new venues or the renovation of old ones. In part two, the book C. Presents a set of famous European rock and pop venues, their architecture, their beauty and their properties. D. These Venues are assessed by a new and comparably simple method to objectively rate halls. Subjective data complete the assessment and give a full picture of the sound quality of a venue.

  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.

  12. The promise of performative: Relational, genetic and scripted models in architectural design

    Directory of Open Access Journals (Sweden)

    Stojanovic Đorđe

    2013-01-01

    Full Text Available This paper investigates the role of performative models within the context of architectural design. Understanding the performances of the built environment can be postulated in rather different manners. It is commonly expected that the built environment complies with the diverse and changing requirements of its users. It is equally required that buildings are economically constructed, easily maintained, energy efficient, safe and aesthetically pleasing. Yet, such expectations are complex and consist of a great number of intertwined effects that are not easy to synchronize during architectural design process. Although they can be precisely evaluated and quantitatively expressed, the values specifying the performances, such as temperature, humidity and intensity of light or sound, in traditionally established course of architectural design are usually only considered throughout the post-rationalization or correction of the architectural design. The research presented in this paper explores design mechanisms, for direct and formative incorporation of feedback information into the very conception of architectural form.

  14. 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

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

    Directory of Open Access Journals (Sweden)

    2014-05-01

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

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

    2015-12-01

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

  11. The processing architectures of whole-object features: A logical-rules approach.

    Science.gov (United States)

    Moneer, Sarah; Wang, Tony; Little, Daniel R

    2016-09-01

    In this article, we examine whether dimensions comprising the entirety of an object (e.g., size and saturation) are processed independently or pooled into a single whole-object representation. These whole-object features, while notionally separable, sometimes show empirical effects consistent with integrality. A recently proposed theoretical distinction between integral and separable dimensions that emphasizes the time course of information processing, can be used to differentiate whether whole-object features are processed independently, either in serial or in parallel, or pooled into a single coactive process (see, e.g., Little, Nosofsky, Donkin, & Denton, 2013). The current research examines this theoretical distinction in the processing of 3 sets of whole-object-featured stimuli that vary on any pair of the dimensions of saturation, size, and orientation. We found that a mixture of serial and parallel architectures underlies the processing of whole-object features. These results indicate that whole-object features are processed independently.

  12. 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.

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.

    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

  4. 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.

    Umut Durmus

    2010-12-01

    Full Text Available Proposal: Architectural design companies increasingly recognize that time spent on management is not at the expense of their production and there are always better ways to organize business. Although architects have long placed a traditional emphasis on quality, quality management is still a new concept for the majority of architectural design companies, which have to organize relatively more complicated operations nowadays to meet their clients’ expectations. This study aims to understand how architectural design companies define quality and explores the extent to which Total Quality Management (TQM principles like continual improvement, employee involvement, customer satisfaction and others can be pertinent in these companies. Adopting a qualitative research strategy, the authors interviewed with the owner-managers of 10 widely-recognized architectural design companies of different size in Istanbul. The results from the content analysis of semi-structured interview data suggest that i TQM principles cannot be directly applied in architectural design companies without an appropriate translation; ii special characteristics of design services are important to explain quality-related perceptions of owner-managers; iii the owner-managers feel the pressure from the changing internal and external environmental conditions, however few of them adopt a systematic and documented approach to quality management. Architectural design offices which aim to establish a quality management system can benefit from this study to understand potential problem areas on their road.

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.

  12. Postindustrial Architecture, Dynamic Complexity and the Emerging Principles of Strategic Design

    Directory of Open Access Journals (Sweden)

    Leonard Bachman

    2012-11-01

    Full Text Available The transition from industrial era society to postindustrial society has shifted architecture away from being a predominantly cultural activity, one that is primarily focused on the physical attributes of a design. The newer architectural orientation leans more toward social ideals and strategic missions. These two perspectives have always coexisted in the discipline and critique of architecture, but the traditional subjugation of strategic concerns is eroding. The two aspects should now be considered in a more explicitly unified and mindful way. In that sense, the transition is not between two factions of practitioners with different philosophies, but between two aspects of thought balanced in some manner by each architect. The ultimate intentions of this paper are first to examine the forces of postindustrial change and then to outline a set of principles which establish strategic design as an architectural activity tantamount to, compatible with, and discursively engaged by physical design.

    Martin Synthesis yields quasi--delay-insensitive (QDI) circuits, expressed in production--rule-set (PRS) form. Under an atomic circuit evaluation model, these circuits are provably correct. 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...

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

    CHEN Hong-song; JI Zhen-zhou; HU Ming-zeng

    2007-01-01

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

  14. Business Model Design and Architecture for the Internet of Everything

    Directory of Open Access Journals (Sweden)

    2016-04-01

    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.

  15. 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.

    2012-02-01

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

    This paper details a set of self-supporting and illuminated panels that work together but independently in order to emphasize the explanation of building features and activities that are based on Universal Design guidelines. The exhibition is based on two structures that are arranged in semi-circles (A and B). They are integrated to form a carpeted path where the visitor will be gradually exposed to the concepts related to the principles of Universal Design. Following the sequence of three-dimensional objects and swivelling box elements that support the tactile information on the subject, it is expected that visitors become familiar with each of the principles being demonstrated. Operated by a control system consisting of keys with colour signage, textures and high relief, the panel on the control table allows the user to choose information about paired relationships between some of seven principles contained in printed images about the architectural design on the set of panels. The effectiveness of the composition can be verified by the time people remain enough to hear, see and touch the kiosks for all the information, or by successive visits users make to the setting.

  18. Design Approach for Fault Tolerance in FPGA Architecture

    Directory of Open Access Journals (Sweden)

    Ms. Shweta S. Meshram

    2011-03-01

    Full Text Available Failures of nano-metric technologies owing to defects and shrinking process tolerances give rise tosignificant challenges for IC testing. In recent years the application space of reconfigurable devices hasgrown to include many platforms with a strong need for fault tolerance. While these systems frequentlycontain hardware redundancy to allow for continued operation in the presence of operational faults, theneed to recover faulty hardware and return it to full functionality quickly and efficiently is great. Inaddition to providing functional density, FPGAs provide a level of fault tolerance generally not found inmask-programmable devices by including the capability to reconfigure around operational faults in thefield. Reliability and process variability are serious issues for FPGAs in the future. With advancement inprocess technology, the feature size is decreasing which leads to higher defect densities, moresophisticated techniques at increased costs are required to avoid defects. If nano-technology fabricationare applied the yield may go down to zero as avoiding defect during fabrication will not be a feasibleoption Hence, feature architecture have to be defect tolerant. In regular structure like FPGA, redundancyis commonly used for fault tolerance. In this work we present a solution in which configuration bit-streamof FPGA is modified by a hardware controller that is present on the chip itself. The technique usesredundant device for replacing faulty device and increases the yield.

    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

    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...

    Full Text Available Sustainable development has been approved by many experts as the only suitable model for the growth of the next generation. Education has a valuable role to distribute sustainable approach to all subject fields like architecture. Sustainable development is gaining a central position in the conceptual framework of architectural education in universities. Universities are complex organizations that are frequently quite stable in the short term, but inevitably evolving over the longer term in response to changes in the societies. At the moment, there are various debates for changing non-renewable with more renewable and efficient architectural design strategies. Architectural Design has always attempted to merge the practicalities of engineering, technology, culture, and economy with the subtle elements of interface, social concerns and aesthetic desire. It has a crucial place for to engage with the sustainable strategies that provide countless environmental, economic, community, health and safety benefits. The education of the students about opportunities, risks, benefits and scientific knowledge of sustainable approach provide valuable contribution towards integral relationships. The theory lessons concentrate mainly on climate, thermal comfort, materials, and optimization of performance, environment and energy fields. Curriculum, knowledge and the teaching methods are connected with each other, especially on the search for the innovative ideas. As innovative ideas emerge, data available for the design process increases. However, such new data cannot be integrated to the design education as desired by current conventional teaching methods in a reliable context. At some points, this situation inhibits the creation of innovative ideas in architectural design. In order to acquire such data and to flourish a sustainable society accordingly, fast and efficient access to knowledge databases is needed. In this study, the research evaluates the current

    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

    Full Text Available This paper discusses the architectural education and models of education practiced in the schools of Architecture and Urbanism in Brazil, particularly in the disciplines of architectural design, through the insertion of information and communication technologies in everyday life of students and teachers. Aiming to discuss the effective use of resources in the design studio, made a brief analysis of the pedagogical practices applied in these disciplines in Brazilian schools nowadays. The aim is also to reflect on possible discrepancies between the evolution of tools to support design and development of teachers of design qualifications. Through these discussions and analysis is intended to contribute to an evaluation of the qualifications needed by teachers of design today - and those who act in the future- and pedagogical practices to be used at a time, now imminent, in which the use of virtual tools will predominate and that teachers need to talk with your student in compatible language.

    Martin-Alvarez, A.; Hayati, S.; Volpe, R.; Petras, R.

    1999-01-01

    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.

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

    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.

  9. 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.

  10. Architectural design of the science complex at Elizabeth City State University

    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

  12. 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.

  2. 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

    Full Text Available This paper1 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 thearchitecture of MPUs. These specialized processors perform unique medical functions encoded as medicaloperational codes (mopcs. From a pragmatic perspective, MPUs function very close to CPUs. Bothprocessors have unique operation codes that command the hardware to perform a distinct chain of subprocessesupon operands and generate a specific result unique to the opcode and the operand(s. Inmedical environments, MPU decodes the mopcs and executes a series of medical sub-processes and sendsout secondary commands to the medical machine. Whereas operands in a typical computer system arenumerical and logical entities, the operands in medical machine are objects such as such as patients, bloodsamples, tissues, operating rooms, medical staff, medical bills, patient payments, etc. We follow thefunctional overlap between the two processes and evolve the design of medical computer systems andnetworks.

    Materials' design for high-performance thermoelectric oxides is discussed. Since chemical stability at high temperature in air is a considerable advantage in oxides, we evaluate thermoelectric power factor in the high temperature limit. We show that highly disordered materials can be good thermoelectric materials at high temperatures, and the effects of strong correlation can further enhance the figure of merit by adding thermopower arising from the spin and orbital degrees of freedom. We also discuss the Kelvin formula as a promising expression for strongly correlated materials and show that the calculation based on the Kelvin formula can be directly compared with the cross-layer thermopower of layered materials.

    Woyak, Scott; Kim, Hongman; Mullins, James; Sobieszczanski-Sobieski, Jaroslaw

    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.

    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.

    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.

  13. 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.

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

    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.

    EChO is a three-modules (VNIR, SWIR, MWIR), highly integrated spectrometer, covering the wavelength range from 0.55 $\\mu$m, to 11.0 $\\mu$m. The baseline design includes the goal wavelength extension to 0.4 $\\mu$m while an optional LWIR module extends the range to the goal wavelength of 16.0 $\\mu$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.

    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.

  10. 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.

    2013-01-01

    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.

    Directory of Open Access Journals (Sweden)

    Carolina Sepúlveda M.

    2016-01-01

    Full Text Available Architectural training has always been linked to two opposed and complementary processes: creative thinking and linear/technical thinking. Nowadays, the training process of an architect is usually based on an experimental design studio, which is complemented by the formal teaching of theoretical and technical subjects. This system is based on the idea that it will produce a comprehensive professional who is capable of achieving creative, appropriate and viable solutions. However, this teaching method can carry hidden difficulties that may hinder the development of architecture students to their full potential. This article will inform on the methodology and results of applying an innovative method of teaching and learning architecture. This method aims at maximising the capacity of students to integrate their creative and technical competencies in order to increase the quality of work of future architects.

    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.

    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.

  4. Architectural Kansei of ‘Wall’ in The Façade Design by Le Corbusier

    Science.gov (United States)

    Sendai, Shoichiro

    The purpose of this paper is to discuss the modern architect Le Corbusier's architectural Kansei (sensibility) on wall in site environment through the analysis of his façade design, using Œuvres complètes (1910-1965, 8 vols., Les éditions d'architecture, Artemis, Zurich) and Le Corbusier Archives (1982-1984, 32 vols., Garland Publishing, Inc. and Fondation Le Corbusier, New York, London, Paris). At first, I arrange five façade types, according to the explanation by Le Corbusier ; ‘fenêtre en longueur (strip window)’, ‘pan de verre (glass wall)’, ‘brise-soleil (sun-breaker)’, ‘loggia’ and ‘claustra’. Through the analysis of the relationship between these types and the design process of each building, we find that Le Corbusier's façade design includes the affirmation and the negation of the ‘wall’ at the same time. In fact, the nature of façade modification during design process is divers: increase in transparency, decrease in transparency and spatialization of façade. That means, Le Corbusier studied the environmental condition by these façade types, and tried to realize the phenomenal openness. This trial bases on the function of architectural Kansei as correspondence between body and environment beyond the physical design.

    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.

  9. 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.

  10. 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.

    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.

  12. 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.

    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.

Relying on the Semantic Web technologies, this paper offers a rule-based architecture supporting delivery of contextualized information. The core functionality is fulfilled by the relevance assessment rule engine, which can re-configure the behavior of the system by specifying the different rule sets. It defines an ontology-based context model, which formalizes the context from different information sources and characterizes the contextual situations of mobile users. Qualitative evaluation results that the architecture has the generality and adaptability; thus can assist mobile police to take decisions during their activities.

    The construction of a school is the first pedagogical act. Its form, the relationship with nature, light, materials and colours provides important educational inputs for children. Different social, philosophical, pedagogical and architectural theories on the spaces built for and around the child have led to the construction of different kindergartens based on fantasy, over-design, sobriety, philosophical theories, and so on. Kindergartens with a surplus of architecture and furniture may reduce the child's imagination, because they are perceived as a too elaborate toy that gets boring. Furniture should provide children with metamorphic forms which adapt to their needs and preferences. The planning and design of buildings and spaces dedicated to children should consider the child at the center of the space built. The aim that architects should have in planning a kindergarten is the well being of the child, because his/her childhood will be the basis of the maturity as adult of tomorrow.

    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.

    We present a method for structural summarization and abstraction of complex spatial arrangements found in architectural drawings. The method is based on the well-known Gestalt rules, which summarize how forms, patterns, and semantics are perceived by humans from bits and pieces of geometric information. Although defining a computational model for each rule alone has been extensively studied, modeling a conjoint of Gestalt rules remains a challenge. In this work, we develop a computational framework which models Gestalt rules and more importantly, their complex interactions. We apply conjoining rules to line drawings, to detect groups of objects and repetitions that conform to Gestalt principles. We summarize and abstract such groups in ways that maintain structural semantics by displaying only a reduced number of repeated elements, or by replacing them with simpler shapes. We show an application of our method to line drawings of architectural models of various styles, and the potential of extending the technique to other computer-generated illustrations, and three-dimensional models.%格式塔(Gestalt)理论总结了人类认知规则、模式和语义的若干规律,已有大量的研究针对独立的格式塔规则建立计算模型,但建立多个格式塔规则相互作用的耦合模型仍然是一个挑战.基于格式塔理论的若干主要规则建立了一个针对多个格式塔规则耦合的计算模型,并将该模型用于建筑物线画图的抽象;通过减少图画中重复结构元素的数目,或者将复杂的结构用简单结构替换的方式对建筑物结构进行概括和抽象.实验结果表明,该方法可以应用于风格各异的建筑物线画图,并可以扩展到其他类型的图画以及三维模型.

    2014-12-01

    Full Text Available In the spatial design fields such as architectural design and urban design, a consensus-building process among a variety of stakeholders like project executors, architects, residents, users, and general citizens is required. New technological developments such as cloud computing and Virtual Design Studios (VDS enable the creation of virtual meeting systems. This paper proposes an approach towards a synchronous distributed design meeting system. In this paper, in addition to sharing a 3D virtual space for a synchronous distributed type design meeting, we developed a prototype system that enables participants to sketch or make annotations and have discussions as well as add viewpoints to them. We applied these functions to evaluate an architectural design and urban landscape examination. In conclusion, the proposed method was evaluated as being effective and feasible. Yet, it shows a few shortcomings including the fact that simultaneous operation is limited to one client, and more arbitrary shapes should be supported in future versions of the application.

  15. The economic analysis of power market architectures: application to real-time market design

    International Nuclear Information System (INIS)

    This work contributes to the economic analysis of power market architectures. A modular framework is used to separate problems of market design in different modules. The work's goal is to study real-time market design. A two-stage market equilibrium model is used to analyse the two main real-time designs: the 'market' and the 'mechanism' (with penalty). Numerical simulations show that design applied in real-time is not neutral vis-a-vis of energy markets sequence and the competition dynamic. Designs using penalty (mechanisms) cause distortions, inefficiencies and can create barriers to entry. The size of distortions is given by the temporal position of the gate that closure the forward markets. This model has also allowed us to show the key role of real-time integration between zones and the importance of good harmonization between real-time designs of each zone. (author)

  16. RESEARCH THROUGH DESIGN: AN ARCHITECTURAL RESPONSE TO PRACTICE-LED RESEARCH

    Directory of Open Access Journals (Sweden)

    Eli Hatleskog

    2014-12-01

    Full Text Available There is a growing trend across the field of architectural research towards a practice-led approach. This has seen researchers move beyond the established limits of quantitative and qualitative research, in pursuit of a new distinct paradigm called 'performative research' [Haseman, 2009]. This type of research allows practitioners to explore and question the issues that they believe are relevant through practice. As such, an architectural researcher may deploy a method called 'research through design', with a view to developing new knowledge. This paper gives an overview of performative research in architecture schools across the world, before discussing forms of design research. It gives an outline of the diverse field in which practice-led research can take place and an insight to the broad spectrum of practices that can supplement practice-led research and the different degrees and balance of methods that may be supported. In turn, this enables a discussion regarding the type of knowledge that can be developed through research by design. 'Relational knowledge' does not necessarily seek a formula or hypothesis, but aims to work in context and between tensions. This type of knowledge can help us to explore connections across a broad field and work across disciplines, in order to gain a deeper understanding of relationships in context and with society

    2011-09-01

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

    Reservoir computing (RC) is gaining traction in several signal processing domains, owing to its non-linear stateful computation, spatiotemporal encoding, and reduced training complexity over recurrent neural networks (RNNs). Previous studies have shown the effectiveness of software-based RCs for a wide spectrum of applications. A parallel body of work indicates that realizing RNN architectures using custom integrated circuits and reconfigurable hardware platforms yields significant improvements in power and latency. In this research, we propose a neuromemristive RC architecture, with doubly twisted toroidal structure, that is validated for biosignal processing applications. We exploit the device mismatch to implement the random weight distributions within the reservoir and propose mixed-signal subthreshold circuits for energy efficiency. A comprehensive analysis is performed to compare the efficiency of the neuromemristive RC architecture in both digital(reconfigurable) and subthreshold mixed-signal realizations. Both Electroencephalogram (EEG) and Electromyogram (EMG) biosignal benchmarks are used for validating the RC designs. The proposed RC architecture demonstrated an accuracy of 90 and 84% for epileptic seizure detection and EMG prosthetic finger control, respectively.

The system, which has been proven within the participation in the ICSI (Intelligent Cooperative Sensing for Improved traffic efficiency) European project, encompasses the entire process of capture and management of available road data. For this purpose, it applies a combination of cooperative services and methods for data sensing, acquisition, processing and communication amongst road users, vehicles, infrastructures and related stakeholders. Additionally, the advantages of using the proposed system are exposed. The most important of these advantages is the use of a distributed architecture, moving the system intelligence from the control centre to the peripheral devices. The global architecture of the system is presented, as well as the software design and the interaction between its main components. Finally, functional and operational results observed through the experimentation are described. This experimentation has been carried out in two real scenarios, in Lisbon (Portugal) and Pisa (Italy).
