▼ Il controllo delle velocità rappresenta un importante strategia per il miglioramento della sicurezza stradale, in considerazione della stretta relazione tra velocità e severità degli incidenti. Lo strumento principale per il controllo della velocità è rappresentato dall imposizione di limiti. La definizione del limite di velocità più corretto però non è una problematica di facile risoluzione, poiché entrano in gioco numerosi fattori in contrasto gli uni con gli altri: chi ha il compito di fissare tali limiti deve, infatti, cercare di bilanciare la sicurezza degli utenti della strada, i tempi di percorrenza, oltre a tutti gli altri fattori che determinano la scelta della velocità (come le caratteristiche dell infrastruttura), considerando altresì l applicabilità e la credibilità dei limiti stessi. Al momento non esiste una metodologia generalmente accettata che consenta di individuare il limite di velocità più appropriato per un determinato tronco stradale tenendo conto contemporaneamente di tutti questi fattori. Obiettivo del presente lavoro è stato quello di sviluppare un Sistema di Supporto alle Decisioni che aiuti il decisore a definire limiti di velocità sicuri e credibili da adottare in zone particolari del tracciato, tenendo conto di numerosi fattori quali le caratteristiche geometriche, il tasso d incidentalità, le condizioni di traffico ed ambientali, etc Il Sistema messo a punto si basa su un analisi di tipo multi-criteriale mediante il Dominance-based Rough Set Approach (DRSA) che, sulla base delle informazioni necessarie alla determinazione delle decisioni esemplari date da un gruppo di esperti, consentirà la costruzione di un modello decisionale di facile comprensione, espresso mediante regole decisionali del tipo se allora . Il Sistema di Supporto alle Decisioni presentato in questa sede, è stato sviluppato prendendo in considerazione un unica tipologia di strade, ossia le strade extraurbane secondarie (strade statali o provinciali), ma può essere facilmente modificato ed adattato alle esigenze del gestore o ai dati disponibili, sia in termini di attributi descrittivi che concorrono alla determinazione del limite di velocità, che in termini di obiettivi da perseguire (e dunque in termini di decisioni prese da differenti tipologie di esperti ). In particolare nel presente lavoro di tesi, oltre ad un applicazione per la determinazione di limiti di velocità di tipo statico, viene mostrata un applicazione per la determinazione di limiti di velocità di tipo dinamico da utilizzare in sistemi ITS o ISA - e per la determinazione di limiti di velocità definiti da differenti decisori.

▼ Rivers and their ecosystems are a vital core of human societies: not only do they provide resources, in particular for rural economies, they also generate symbolic meanings in different cultures around the world. The Dissertation focuses on how watershed planning and management can be enhanced with the purpose of improving the relationship of human communities and natural ecosystems. This work is located within the growing debate, in the field of environmental planning, focused on the necessity to integrate scientific knowledge with a broader understanding of how social-ecological system works (Gunderson and Hollings 2001) and how communities use various types of knowledge to innovate the way they relate with natural resources; (Ostrom 2009, Fischer 2009). Two detailed cases are presented: the Mississippi communities relating with the Delta-Yazoo River basin and Pascuagoula River basin, MS, U.S.A.; the Simeto communities relating with the Simeto River Valley, Sicily, Italy. In both cases, innovating watershed planning through stakeholders collaboration faces significant difficulties, related with long-term socio-cultural struggles. Mississippi is explored through Case Study Research; the inquiry identifies the necessity of questioning bottom-up and collaborative practices in the light of reflections about dynamics of power; research also shows that even in a very challenging context there are windows of opportunities; in this case, various stakeholders agree on the necessity of improving various forms of education, integrating environmental and social-cultural issues. The Mississippi case highlights a clear indication, for planning discipline, to bridge the traditional divide between scientific environmental knowledge and the problem of democracy. The Simeto case is a narrative of the direct engagement of the author in a Participatory Action Research (PAR) process, which was generated with questions about the need of linking environmental restoration with social-cultural and democratic innovations, so that the Mississippi conclusions are the starting point of the Simeto narrative. According with the nature of PAR methodology, in which knowledge is collectively produced and continuously reshaped through action, the narrative shows how the Simeto community has learned through a democratic approach to research, in order to innovate watershed planning, to promote the democratic dialogue and to affect institutions. From a methodological standpoint, the Dissertation discusses how Case Study Research relates with Participatory Action Research. The Dissertation offers various details on practical devices, mostly related to the need of facing challenges and changes through a process of collective re-framing and through community-based education, not only to enhance the health of river s ecosystem, but also to improve communities quality of life.

▼ Urban pluvial flooding is stressing urban areas with increasing frequency, becoming a factor of great concern. Soil sealing resulting from urban development is one of the main reasons for changes in natural hydrological processes and related recurring failures of urban drainage systems, especially during heavy rainfall events. Today, several studies are looking at the concept of urban resilience as a new paradigm, for a better integration of issues of water and flood risk with urban planning. Resilience is viewed as a way to tackle risk, showing bonds with its different sections, among which the flood hazard. It is broadly agreed that spatial planning, by incorporating Sustainable urban Drainage Systems (SuDS) within tools and polices, helps to build urban flood resilience. In particular, SuDS, as alternative strategy for surface water management, could potentially address anthropogenically generated hazard, thanks to the water-flow regulating service and benefits they provide. This research explores the relationship between the risk of urban pluvial flooding, resilience and urban planning. Particularly, the concept of resilience is clarified in order to highlight how it contributes to both analyse urban systems by adding levels of knowledge, and steer planning and policy approaches towards the mitigation of pluvial flood risk. By applying a research methodology based on the use of EPA-Storm Water Management Model (SWMM), the main aim of the thesis was to define a proper methodology and to build-up an analytical tool in order to analyse and assess the urban system s response to rainfall events, and to be used during and for purposes of the planning process. The proposed methodology is open to be flexibly applied to aptly handle the previous issues. Accordingly, the purpose was twofold: to assess the impact of masterplan in terms of increase of flow peak releases from urban catchments concerned by planned urban developments; to examine the urban system s reaction to rainfall and to evaluate how the response is affected by SuDS implementation at the catchment level. Case study areas were selected in the cities of Catania and Avola, in Sicily, for which masterplans design has been recently proposed by local planning authorities. Simulation of scenarios were carried out for a number of design storm events of selected return periods. Input parameters for the modelling were derived from urban analyses and hydrologic analyses and processing. Firstly, the methodology was based on the comparison between pre- and post-development catchment release scenarios and was applied to a case study catchment in the southern part of Catania. The study showed the need of careful consideration of the hydraulic invariance principle in land use planning practices. In particular, a set of flow release restrictions were determined for new areas of development, achieving the condition of unvaried flow peaks at the sub-catchment level, for different return periods of the storm-water event. Secondly, the methodology was applied to selected urban…

▼ Graphic Processing Units (GPUs) are originally mainly designed to accelerate graphic applications. Now the capability of GPUs to accelerate applications that can be parallelized into a massive number of threads makes GPUs the ideal accelerator for boosting the performance of such kind of general-purpose applications. Meanwhile it is also very promising to apply GPUs to embedded and real-time applications as well, where high throughput and intensive computation are also needed. However, due to the different architecture and programming model of GPUs, how to fully utilize the advanced architectural features of GPUs to boost the performance and how to analyze the worst-case execution time (WCET) of GPU applications are the problems that need to be addressed before exploiting GPUs further in embedded and real-time applications. We propose to apply both architectural modification and static analysis methods to address these problems. First, we propose to study the GPU cache behavior and use bypassing to reduce unnecessary memory traffic and to improve the performance. The results show that the proposed bypassing method can reduce the global memory traffic by about 22% and improve the performance by about 13% on average. Second, we propose a cache access reordering framework based on both architectural extension and static analysis to improve the predictability of GPU L1 data caches. The evaluation results show that the proposed method can provide good predictability in GPU L1 data caches, while allowing the dynamic warp scheduling for good performance. Third, based on the analysis of the architecture and dynamic behavior of GPUs, we propose a WCET timing model based on a predictable warp scheduling policy to enable the WCET estimation on GPUs. The experimental results show that the proposed WCET analyzer can effectively provide WCET estimations for both soft and hard real-time application purposes. Last, we propose to analyze the shared Last Level Cache (LLC) in integrated CPU-GPU architectures and to integrate the analysis of the shared LLC into the WCET analysis of the GPU kernels in such systems. The results show that the proposed shared data LLC analysis method can improve the accuracy of the shared LLC miss rate estimations, which can further improve the WCET estimations of the GPU kernels.

▼ Modern mobile platforms are embracing not only heterogeneous but also loosely coupled computational resources. For instance, a smartphone usually incorporates multiple processor cores that have no hardware cache coherence. Loosely coupled resources allow a high degree of resource heterogeneity that can greatly improve system energy efficiency for a wide range of mobile workloads. However, loosely coupled resources create application programming difficulty: both resources and program state are distributed, which call for explicit communication for consistency. This difficulty is further exacerbated by the large numbers of mobile developers and mobile applications. In order to ease application programming over loosely coupled resources, in this thesis work we explore system support – at both user level and OS level – that bridges desirable programming abstractions with the underlying hardware. We study three loosely coupled architectures widely seen in mobile computing: i) a smartphone accompanied by wearable sensors, ii) a mobile device encompassing multiple processors that share no memory, and iii) a mobile System-on-Chip (SoC) with multiple cores sharing incoherent memory. In order to address the three architectures, this thesis contributes three closely related research projects. In project Dandelion, we propose a Remote Method Invocation scheme to hide communication details from application components that are synchronizing over wireless links. In project Reflex, we design an energy-efficient software Distributed Shared Memory (DSM) to automatically keep user state consistent; the DSM always employs a low-power processor to host shared memory objects in order to maximize sleep periods of high-power processors. In project K2, we identify and apply a shared-most OS model to construct a single OS image over loosely coupled processor cores. Following the shared-most model, high-level OS services (e.g., device drivers and file systems) are mostly unmodified with their state transparently kept consistent; low-level OS services (e.g., page allocator) are implemented as separate instances with independent state for the sake of minimum communication overhead. We report the research prototypes, our experiences in building them, and the experimental measurements. We discuss future directions, in particular how our principles in treating loosely coupled resources can be used for improving other key system aspects, such as scalability.

▼ Microservices architecture is popular for its distributive system styles due to the independent character of each of the services in the architecture. Microservices are built to be single and each service has its running process and interconnecting with a lightweight mechanism that called application programming interface (API). The interaction through microservices needs to communicate internally. Microservices are a service that is likely to become unreachable to its consumers because, in any distributed setup, communication will fail on occasions due to the number of messages passing between services. Failures can occur when the networks are unreliable, and thus the connections can be latent which may lead to failure or slow response. This might be a problem for synchronous remote calls actively waiting for a response. If they do not use a proper timeout mechanism, they may end up waiting for an extended amount of time. Applications usually set a timeout for all remote calls to avoid hanging of the whole application due to network failure or component failure. However, this timeout needs to be set carefully to make the system or microservice application to work as required. This would prevent further problems because if a remote call is waiting too long for a reply, it can slow down the system in its entirety, and if a connection timeout is extremely fast, it may ignore a response that is sent after timeout. This thesis proposes a dynamic fault tolerance (DFTM) Model to improve the stability and resilience of the microservices architecture. The Model is designed using a two-states Circuit Breaker called Switch Circuit Breaker with Markov-Chain. In addition, a modified Circuit Breaker (three states – open, closed, and half-open) to Switch Circuit Breaker (two states – open and closed) is presented here. The Circuit Breaker uses timeout to detect fault but timeouts usage hinges on assumptions about the real-time behavior of the system and awaiting process can be deduced from the occurrence of a timeout that a failure has occurred. Therefore, DFTM model adopted Markov Chain based model to detect fault without a timeout. Then, it sends the fault directly to Switch Circuit Breaker that uses a 2-states to cover the faults. An important finding is that the DFTM model presents a solution to the problem of transient failures or faults in the interservice communication of microservices architecture. Also, it improves the performance and reliability of microservices architecture. Advisors/Committee Members: Yi Liu.

▼ Enterprise architecture is a relatively new concept that arose in the latter half of the twentieth century as a means of managing the information technology resources within the enterprise. Borrowing from the disciplines of brick and mortar architecture, software engineering, software architecture, and systems engineering, the enterprise architecture discipline struggles to define itself and demonstrate that it is a worthwhile endeavor that is capable of producing measurable benefits for the enterprise. Studies continue to show that most large IT projects are laborious struggles that are perpetually overdue, over-budget and deliver functionality that consistently under performs what was intended. Enterprise architecture is supposed to help lead to order out of the chaos, but the current success rate does not appear to be appreciably higher than it was before enterprise architecture was widely employed. The key to developing a successful enterprise architecture lies in making it more beneficial as well as less costly. This requires not only knowing how enterprise architecture should be developed, but also knowing what obstacles lay in the path of success. There are many reasons why an enterprise architecture effort can fail, but there are three challenges in particular that obstruct enterprise architecture efforts greatly. These challenges are wicked problems, complexity, and the enterprise learning curve. The goal of this research has been to discover strategies that can help attenuate the difficulties that result from wicked problems, complexity, and the enterprise learning curve and also to improve the chances of developing an enterprise architecture that delivers a positive return on investment for the enterprise. Towards this goal, this research makes the following contributions: • It establishes the focus and scope of enterprise architecture by defining the bounds of what enterprise architecture should address. • It develops a core set of enterprise business questions from which to begin enterprise architecture development. • It develops an enterprise architecture metamodel named the Maintain Accountability, Produce Product, and Manage Resources enterprise architecture metamodel that supports enterprise architecture metamodel development. • It develops a methodology that aids the enterprise architect in focusing the development effort on obtaining significant value while reducing the risk of expending resources developing architectural artifacts of little or no value. • It develops an enterprise architecture case study framework that extends both the Freidman-Sage and Martin case study frameworks for systems engineering case study research, and provides an enterprise architecture case study framework that shares a common basis for evaluating enterprise architecture case studies in the same conceptual framework as prior system engineering case study research.

▼ This study is a descriptive investigation of the cultural and systemic processes of legitimizing subject matter being introduced into the curriculum of an undergraduate architecture program. The culture being observed and interviewed during their day-to-day encounters with curriculum and its modification is one university’s department of architecture. Legitimization is used here to mean the progress that innovative subject matter makes from being initially ill defined and informally included with instruction, to being well defined by cultural agreement and systemic records, and finally considered an integral part of the curriculum with recognized status as a title in the university’s course catalog. Employing ethnomethodological strategies, the investigator maintains prolonged contact with the members of this culture, taking advantage of the opportunities to watch and interrogate legitimization and curriculum modification taking place in the domain of sustainable architecture. Much of this happens in the face of disturbances to these processes and the culture’s reactions to those disturbances. These disturbances and reactions make the underlying processes observable and explicit to an extent not revealed under ordinary circumstances. There are three main audiences for this study: instructional designers, architectural design educators, and those interested in sustainability and its status in a design curriculum. While sustainability for its own sake was not the primary focus here, how sustainability is emerging in this culture’s instruction and curriculum should be of interest to the latter group. Where this study is intended to provide a fundamental contribution is at the intersection of instructional design and design instruction. To date, little in the instructional systems literature discusses the architecture studio and its crucial role in architecture degree programs. When it comes to how learning objectives should or should not be applied to studio courses and curricula, the literature of architectural design education has not dealt comprehensively with systemic institutional pressures for assessment. Again, this is a descriptive study of a single department, and a glimpse into the ways that culture deals with these issues.

Mestrado em Gestão das Organizações : Ramo de Gestão de Empresas (parceria com a APNOR) na Escola Superior de Tecnologia e Gestão do Instituto Politécnico de Viana do Castelo

A utilização dos Sistemas de Informação/Tecnologia de Informação (SI/TI) passou a ser vista como uma das principais ferramentas de auxílio à gestão de topo, para melhor conduzirem as organizações e, assim, obterem vantagens competitivas. Face a isto, as Instituições de Ensino Superior, em muitas partes do mundo, aproveitam estes SI/TI para melhorar os seus processos educativos e administrativos e, assim, torná-los eficientes e eficazes. O aumento das Instituições de Ensino Superior em Angola e a procura do acesso a um curso de Ensino Superior, fez com que os gestores de topo recorressem a estes SI/TI, para melhor gerirem as suas Instituições, tanto no aspeto académico como administrativo. O uso dos SI/TI na Educação evoluiu muito nos últimos anos, mas a sua presença é mais notória no âmbito académico, como apoio didático, como instrumento nas atividades de ensinoaprendizagem, em especial na Educação à Distância. No âmbito da gestão das Instituições de Ensino Superior, os SI/TI evoluíram de um mercado comercial e industrial, sofrendo assim com problemas de adaptação, pois estes não foram criados originalmente para este mercado. O presente projeto tem como finalidade o planeamento da adoção de um sistema de informação de gestão académica numa perspetiva de desenvolvimento de um segmento de arquitetura de empresa no Instituto Superior Politécnico do Kwanza Sul/Angola, tendo seguido as seguintes fases: Iniciação, Definição de Benefícios, Arquitetura de Negócio, Arquitetura de Dados, Arquitetura da Aplicação, Arquitetura Tecnológica e o Plano de Construção, realizadas com vista a responder a esse objetivo. O presente projeto aponta para que a implementação do mesmo no Instituto Superior Politécnico do Kwanza Sul/Angola seja uma mais-valia para o Instituto, suportando a sua estratégia de desenvolvimento, trazendo em particular os seguintes benefícios: melhores indicadores para o planeamento estratégico, melhor tomada de decisão dia-a-dia, melhor controlo e supervisão e redução da carga administrativa.

De nos jours, les systèmes embarqués sont les éléments Cœurs des Systèmes avioniques. De plus en plus de fonctions sont intégrées et de ce fait leurs complexités croît. Afin que cette complexité puisse rester maîtrisable, l’architecture des systèmes avionique a également évolué de façon à minimiser les interactions entre les équipements. Cette évolution des Architectures a introduit, au niveau avionique, la notion de réseau largement répandue dans le monde dit « consumer ». Nos travaux de Recherche ont pour but d’accompagner cette évolution architecturale en minimisant l’impact des ruptures technologiques qu’il a été nécessaire d’introduire afin de supporter cette évolution. Pour cela, nous proposons une approche qui va nous permettre de dé-risquer chaque nouvelle brique technologique avant son introduction au sein des Systèmes Embarqués. Cette introduction pourra donc être réalisée en ayant au préalable défini les conditions ainsi que les limites d’utilisation de chaque nouvelle technologie, qu’elle soit matérielle et/ou logicielle.

Nowadays, Embedded Systems are key elements of the Avionic Systems. As more and more functions are integrated, their complexity goes increasing. In order to keep mastering this complexity, Avionic Systems Architecture has also evolved so as to minimize the interactions between equipment. This evolution of the Architectures introduced, at the avionic level, the notion of network widely spread in the consumer domain. Our research works aim at accompanying this architectural evolution by minimizing the impact of the technological breakthroughs which were necessary to introduce to support this evolution. For that purpose, we propose an approach which is going to allow us to derisk every new technological brick before its introduction within the Embedded Systems. This introduction can thus be performed by having beforehand defined the conditions as well as the limits of use of every new technology that it is Hardware and/or Software.

▼ A lack of knowledge during conceptual design results in two primary challenges: overruns in cost and schedule due to frequent design changes and combinatorial explosion of alternatives due to large, discrete categorical design spaces. Due to the significant impact subsystem-level technologies have on the cost and schedule of a design, they should be considered during the conceptual design of systems of systems in an effort to reduce this lack of knowledge. To integrate architecture analysis and technology evaluation at the subsystem level, several questions and hypotheses are posed during a discussion of a general concept exploration process to guide the development of a new framework. The Dynamic Rocket Equation Tool (DYREQT) and a collection of subsystem-level in-space transportation models were developed to provide a modeling and simulation environment capable of producing the necessary data for experimentation. DYREQT provides the capability to integrate user-developed subsystem models for space transportation architecture analysis and design. Results from the experiments led to conclusions which guided the definition of the Integrated Architecture and Technology Exploration (IntegrATE) framework. This new framework enables integrated architecture analysis and technology evaluation at the subsystem level in an effort to increase design knowledge during the conceptual design process. IntegrATE provides flexibility such that it can be tailored to a wide range of problems. It also provides a high degree of transparency throughout to help reduce the likelihood of bias towards individual architectures or technologies. Finally, the IntegrATE framework and DYREQT were demonstrated on a notional manned Mars 2033 design study to highlight the utility of these new developments.

Dissertação apresentada à Universidade Fernando Pessoa como parte dos requisitos para obtenção do grau de Mestre em Engenharia Informática, especialização em Sistemas de Informação e Multimédia.

Longe está o tempo em que os Munícipes se deslocavam à Câmara Municipal para entregar, consultar ou simplesmente levantar um processo. Hoje, também pelas necessidades legais, eles exigem ter acesso à informação de uma forma mais rápida e eficaz. A Administração Pública Local enfrenta pois um desafio no âmbito da modernização administrativa, procurando estimular a aproximação dos Munícipes à Autarquia e, ao mesmo tempo, promover a desmaterialização dos processos. Este trabalho surgiu da necessidade denotada por estas mudanças, pelo que se propôs um estudo com a finalidade de encontrar uma arquitectura de informação adequada para a Secção de Obras Particulares do Município. A arquitectura de Informação desempenha um papel importante na função dos Sistemas de Informação, uma vez que permite manter uma visão global dos seus vários aspectos. Para atingir o objectivo proposto foi aplicado o método BSP da IBM com a sua adaptação por Luís Amaral e João Varajão, na sua versão de 2007, ao estudo do caso da Secção de Obras Particulares do Município de Penacova. Foi assim elaborada e concebida a arquitectura da informação para a Secção de Obras Particulares do Município de Penacova, sendo definidos oito grupos de processos (Administração, Atendimento, Saneamento processo, Licenciamento, Alvarás, Acompanhamento Obra, Licença Utilização e Arquivo). Na fase seguinte, foram identificados os principais problemas e definidas as prioridades e recomendações a implementar. Todo o trabalho foi realizado com recolha de informação real e em contexto de trabalho. The time when citizens went to the City Council to deliver, consult or simply obtain a process is long since past. Today, not only due to legal requirements, they demand access to information more quickly and effectively. The Local Public Administration is also facing a challenge under the administrative modernization and wants to bring citizens closer to the municipality, promoting at the same time the dematerialization of processes. This work arose from the given necessity of these changes; as a result, it has been proposed a study with the aim of finding a suitable information architecture for the Private Works Section of the Municipality. The architecture of an information system plays an important role in the function of information systems, since it enables us to keep an overview of its various aspects. To achieve the proposed goal, it was used IBM‟s BSP method with an adaptation by Luís Amaral and John Varajão in its 2007 version of the case study of the Private Works Section of the Municipality of Penacova. Therefore, the information architecture for the Private Works Section of the Municipality of Penacova was developed and designed, being defined eight groups of processes (Administration, Reception, Proceedings, Licensing, Permits, Work Monitoring, License for Use and…

Le bâti traditionnel dans le bassin méditerranéen, avec son riche parcours historique, reflète les nécessités socioculturelles pour lesquelles il a été construit. Les besoins environnementaux interagissent et se superposent en déterminant, en milieu urbain, des solutions typologiques et constructives récurrentes. Les solutions architecturales du bâtiment historique méditerranéen présentent des qualités formelles, structurelles et fonctionnelles remarquables et, grâce à la capacité d'adaptation au contexte climatique local, elles garantissent également un bon niveau de confort environnemental interne. De nos jours, la nécessité de réduire les consommations d’énergie dans le domaine de la construction entraîne le développement de la recherche vers des solutions innovantes qui combinent l’expérimentation sur les nouveaux matériaux et technologies, et la réappropriation des connaissances et des principes de construction de l’architecture « traditionnelle » en milieu dense. Porté par ces thématiques, étendues aux interactions entre les éléments du bâti et l’ensemble des facteurs qui participent à la détermination du confort intérieur des usagers dans les bâtiments traditionnels en région méditerranéenne, notre questionnement de base est parti des interrogations suivantes : pouvons-nous récupérer des savoir-faire techniques perdus ou oubliés pour répondre aux problématiques actuelles de réduction de consommation énergétique des bâtiments ? Comment réinterpréter certains aspects caractéristiques des bâtiments traditionnels avec les technologies et matériaux contemporains ? Quels outils de conception sont à mettre en place? Nous voulions ainsi reconstruire un modèle d'architecture traditionnelle en se concentrant sur une ville en particulier, Palerme, pour sa capacité à illustrer, à travers ses phases historiques, l'évolution d'une métropole méditerranéenne; sur tous les sous-systèmes (ville, bâtiment, composant constructif), nous retrouvons l’idée de transmission, avec des qualités implicites de permanence, d’héritage, de répétition et de durabilité. Ce choix nous permet, également, de cerner notre champ de recherche sans se perdre dans la multitude de variables possibles. En s’appuyant sur des recherches scientifiques actuelles et passées, et sur des calculs numériques réalisés, nous essaierons d’évaluer les performances énergétiques de cette architecture qui est souvent considérée comme une forme empirique d’architecture « bioclimatique ».La connaissance du comportement thermique de ce bâti représente une phase préparatoire fondamentale afin de proposer des outils de conception pour la modélisation et l’évaluation thermique de systèmes technologiques innovants, capables de réinterpréter certains aspects de l’architecture traditionnelle avec la mise en place de matériaux ou techniques contemporains

▼ The importance of a sound Requirements Engineering (RE) process to influence a system’s success or failure cannot be understated. The activities include the elicitation, analysis, modeling, verification / validation, and management of requirements to fully document a capability envisioned by the stakeholder to be constructed and implemented. With the introduction of the System of Systems (SoS) concept, multiple independent program offices are needed to both develop their system roadmaps as well as manage additional capability requirements to enable an emergent and unique capability if all parts of the SoS interoperate together. The challenge is how to allocate SoS requirements to the individual systems to ensure that the capabilities are being achieved without excessive redundancy or omissions in the new requirements. There has been research in the fields of requirements engineering that are typically limited to single systems, lessening the need for allocation concerns. Research in the field of SoS is focused mainly on performance once the configuration is established, or how to manage the SoS once the requirements have already been developed. Little attention has been paid to the issues of collaboration between the stakeholders to determine the initial allocation of the SoS requirements, and ensure that this allocation will properly satisfy the intended objectives. The objective of this research is to develop a SoS RE process to address the initial formation of SoS requirements that may be typically found at the beginning of the systems engineering lifecycle. The proposed process will develop models in order to transform SoS concepts into SoS requirements, and then allocate them to individual systems. Metrics are developed to address how much a particular system may be under/over-tasked to achieve the SoS requirements. A key issue to be addressed in this proposal is to identify when a proposed SoS concept has its requirements improperly allocated to the available configuration, and thus risks failure to achieve the desired capability. The methodology is illustrated through two case studies that highlight the processes and comparisons of SoS configurations to assess the requirements capacity allocation.

▼ The current trend toward chip multiprocessor architectures has placed great pressure on programmers and compilers to generate thread-parallel programs. Improved execution performance can no longer be obtained via traditional single-thread instruction level parallelism (ILP), but, instead, via multithreaded execution. One notable technique that facilitates the extraction of parallel threads from sequential applications is thread-level speculation (TLS). This technique allows programmers/compilers to generate threads without checking for inter-thread data and control dependences, which are then transparently enforced by the hardware. Most prior work on TLS has concentrated on thread selection and mechanisms to efficiently support the main TLS operations, such as squashes, data versioning, and commits. This thesis seeks to enhance TLS functionality by combining it with other speculative multithreaded execution models. The main idea is that TLS already requires extensive hardware support, which when slightly augmented can accommodate other speculative multithreaded techniques. Recognizing that for different applications, or even program phases, the application bottlenecks may be different, it is reasonable to assume that the more versatile a system is, the more efficiently it will be able to execute the given program. As mentioned above, generating thread-parallel programs is hard and TLS has been suggested as an execution model that can speculatively exploit thread-level parallelism (TLP) even when thread independence cannot be guaranteed by the programmer/ compiler. Alternatively, the helper threads (HT) execution model has been proposed where subordinate threads are executed in parallel with a main thread in order to improve the execution efficiency (i.e., ILP) of the latter. Yet another execution model, runahead execution (RA), has also been proposed where subordinate versions of the main thread are dynamically created especially to cope with long-latency operations, again with the aim of improving the execution efficiency of the main thread (ILP). Each one of these multithreaded execution models works best for different applications and application phases. We combine these three models into a single execution model and single hardware infrastructure such that the system can dynamically adapt to find the most appropriate multithreaded execution model. More specifically, TLS is favored whenever successful parallel execution of instructions in multiple threads (i.e., TLP) is possible and the system can seamlessly transition at run-time to the other models otherwise. In order to understand the tradeoffs involved, we also develop a performance model that allows one to quantitatively attribute overall performance gains to either TLP or ILP in such combined multithreaded execution model. Experimental results show that our combined execution model achieves speedups of up to 41.2%, with an average of 10.2%, over an existing state-of-the-art TLS system and speedups of up to 35.2%, with an average of 18.3%, over a flavor of…

▼ A number of modern digital processing systems implement complex multi-mode applications with high performance requirements and strict operating constraints; examples include video processing and telecommunication applications. A number of these systems use increasingly large FPGAs as the implementation medium, due to reduced development costs. The combination of increases in FPGA capacity and system complexity has lead to a non-linear increase in system implementation effort. If left unchecked, implementation effort for such systems will reach the point where it becomes a design and development bottleneck. At the same time, the reduction in transistor size used to manufacture these devices can lead to increased device fault rates. To address these two problems, the Multi-mode Adaptive Collaborative Reconfigurable self-Organized System (MACROS) Framework and design methodology is proposed and described in this work. The MACROS Framework other the ability for run-time architecture adaptation by integrating FPGA configuration into regular operation. The MACROS Framework allows for run-time generation of Application-Specific Processors (ASPs) through the deployment, assembly and integration of pre-built functional units; the framework further allows the relocation of functional units without affecting system functionality. The use of functional units as building blocks allows the system to be implemented on a piece-by-piece basis, which reduces the complexity of mapping, placement and routing tasks; the ability to relocate functional units allows fault mitigation by avoiding faulty regions in a device. The proposed framework has been used to implement multiple video processing systems which were used as verification and testing instruments. The MACROS framework was found to successfully support run-time architecture adaptation in the form of functional unit deployment and relocation in high performance systems. For large systems (more than 100 functional units), the MACROS Framework implementation effort, measured as time cost, was found to be one third that of a traditional (monolithic) system; more importantly, in MACRO Systems this time cost was found to increase linearly with system complexity (the number of functional units). When considering fault mitigation capabilities, the resource overhead associated with the MACROS Framework was found to be up to 85 % smaller than a traditional Triple Module Redundancy (TMR) solution.

▼

This thesis presents a design, implementation and performance benchmark of custom hardware for computing Singular Value Decomposition (SVD) of the radio communication channel characteristic matrix. Software Defined Radio (SDR) is a concept in which the radio transceiver is implemented by software programs running on a processor. SVD of the channel characteristic matrix is used in pre-coding, equalization and beamforming for Multiple Input Multiple Output (MIMO) and Orthogonal Frequency Division Modulation (OFDM) communication systems (e.g., IEEE 802.11n). Since SVD is computationally intensive, it may require custom hardware to reduce the computing time. The pipeline processor developed in this thesis is suitable for computing the SVD of a sequence of 2 × 2 matrices. A stream of 2×2 matrices is sent to the custom hardware, which returns the corresponding streams of singular values and unitary matrices. The architecture is based on the two sided Jacobi method utilizing Coordinate Rotation Digital Computer (CORDIC) algorithms. A 2×2 SVD prototype was implemented on Field-Programmable Gate Array (FPGA) for SDR applications. The 2×2 SVD prototype design can output the singular values and the corresponding unitary matrices in pipeline while operating at a data rate of 324 MHz on a Virtex 6 (xc6vlx240t-lff1156) FPGA. The prototype design consists of fifty-five CORDIC cores which takes 32 percent of available logic on the FPGA. It achieves the optimal pipeline rate equaled to the maximum hardware clock rate. The depth of the pipeline (latency) is 173 clock-cycles for 16-bit data hardware. The proposed architecture provides performance gains over standard software libraries, such as the ZGESVD function of Linear Algebra PACKage (LAPACK) library, which is based on Golub-Kahan-Reinsch SVD algorithm, when running on standard processors. The ZGESVD function of LAPACK implemented in Intel’s Math Kernel Library (MKL) will achieve a projected data rate of 40 MHz on a 2.50 GHz Intel Quad (Q9300) CPU. The pipeline SVD hardware ban width equals the clock frequency and the data rate can reach 324 MHz on the ML605 board (Virtex 6 xc6vlx240t). The proposed architecture also has the potential to be easily extended to solve 4×4 SVD problems used in pre-coding and equalization schemes. The proposed algorithm and design have better performance for small matrices, even though the general timing complexity is n2 when compared to nlog(n) complexity of Brent-Luk-Van Loan (BLV) systolic array using non-pipeline 2×2 processors. The performance gain of the proposed design is at the cost of increased circuit area.

▼ The computer industry's transition to multiprocessor systems on chip (MPSoC) architectures is increasing the need for new scalable high-bandwidth on-chip communication backbones. Network-on-Chip (NoC) interconnects are gaining interest for serving as the on-chip communication infrastructure. The most important issues to be considered in designing a NoC are topology, routing algorithm, flow control, and buffering and also the trade-offs between performance, power, and area. This research proposes a custom-designed NoC specifically for MPSoCs on FPGAs. The proposed design allows the communication infrastructure to seamlessly scale as the numbers of processors within the chip increases. The design adds a new level of abstraction to remote-access transactions. The design also considers support for the partitioned global address space model with support for optional embedded local memories embedded in the network interface. The network was designed as a mesh topology to allow a reasonable communication capacity in 2-Dimensional space. The communication protocol between source and destination is AMBA AXI4, and the communication between each two adjacent nodes, is typical AXI type valid/ready handshake. The nodes are distinguished by their user specified address range. Each node is assigned a range of addresses, and in each transaction, based on the destination address, the routers decide the the next node, until the transaction reaches the destination. The design has been implemented on a Xilinx Virtex7 FPGA. However, there is no platform dependency to any brand or any model of FPGAs. %In the first chapter in this research, we give an introduction of the work. In chapter 2, we talk about the background of MPSoCs and interconnections. We discuss the AXI protocl, and then we specifically talk about different Network-on-Chip projects. In chapter 3, we describe the design details for different component an also the high level design of the system, we also, discuss the implementation details of the design. In chapter 4, we show the experimental results for both verification phase and the analysis of the system. Finally, chapter 5 concludes the research.

▼ Research on computer memory systems has been of increasing importance over the last decade, as they have become a significant bottleneck for application performance. While newer memory systems offer increased memory level parallelism, they cannot be used blindly due to contention for shared resources, making a beneficial and valid sequencing of memory requests requisite in order to exploit these improvements. Traditional approaches to improving this sequencing rely on highly sophisticated memory systems, where significant amounts of inference are often required to make these sophisticated decisions. Unfortunately, this design philosophy may no longer be sustainable. For example, as memory clock frequencies continue to scale while processor frequencies remain stagnant, sophisticated memory controllers are already being squeezed out, forcing computer architects to revert to simpler designs. We use this as an opportunity to symbiotically involve the processor cores in the decision-making process, simultaneously offloading the complexity from these memory decision makers while extracting richer information on each memory operation. This work studies the concept of load criticality, where the processors themselves identify the loads which they believe to be most important. Using loads that block at the end of the processor pipeline as an indicator of criticality, we annotate these load block predictions onto memory requests, for use by various components in memory. Our research finds that even using small, sim- ple predictors for load criticality can offer comparable performance to complex state-of-the-art schedulers for both parallel applications and multiprogrammed workloads on a contemporary multicore system. This same predictor can be used to obtain significant performance improvements and energy savings when using hardware prefetchers. Ultimately, our criticality-aware design approach achieves the performance of traditionally-complex memory systems, and does so with trivial overheads that are attractive for future commercial adoption.
