Повний текст джерелаNowadays, we expect of SoS (systems-of-systems) more than just to be functional, but also to be reliable, to preserve their performance, to complete the required fonctions and rnost importantly to anticipate potential defects. The relationship with resilience is among the numerous perspectives tackling reliability in the context of SoS. It is about the consequences in case of disturbances and associated uncertainties. Resilience is defined as the ability of systems to withstand a major disruption within acceptable degradation parameters and to recover within an acceptable time, composite costs and risks. In this thesis, two complementary approaches are proposed in an attempt to analyze SoS structural resilience. First is related to extensibility which is a specific characteristic of SoS as they are in continuous evolvement and change. A major focus is to evaluate SoS structural resilience with regards to its dynamic aspect and through interoperability assessment. On the other hand, a consideration of the SoS structure and inner workflow pathways represents the second approach. This perspective leads to structural resilience assessment through a set of indicators. Both proposed approaches are deterministic and can be used to evaluate the current state of SoS structure or to anticipate its resilience in future scenarios. Futhermore, a prototype is designed in order to process the structural resilience assessment. Considering spatial objects, it has been used to conduct experiments on real-based industrial infrastructures approached as SoS

Повний текст джерелаand discussion of various isolator types are involved in this work. Seismic isolation consists essentially of the installation of mechanisms, which decouple the structure, and its contents, from potentially damaging earthquake induced ground motions. This decoupling is achieved by increasing the horizontal flexibility of the system, together with providing appropriate damping. The isolator increases the natural period of the overall structure and hence decreases its acceleration response to earthquake-generated vibrations. This increase in period,together with damping, can reduce the effect of the earthquakes, so that smaller loads and deformations are imposed on the structure and its components. The key references that are used in this study are the related chapters of FEMA and IBC2000 codes for seismic isolated structures. In this work, these codes are used for the design examples of elastomeric bearings. Furthermore, the internal forces develop in the superstructure during a ground motion is determined

is becoming very popular in terms of attaching prestige to a project and improving its desirability. However too many buildings are claimed to be intelligent and adaptive to change but, without an appropriate understanding of intelligent building concept and also capabilities of assessing an intelligent building, it is not possible to judge such claims. In view of the fact that truly intelligent buildings provide their occupants with efficient facilities and comfortable space, many experts and researchers have discussed the characteristics of intelligent buildings and come up with different definitions and assessment systems, but none agree with each other completely. The aim of this study was to evaluate intelligence in intelligent buildings and provide responsiveness clues in terms of system efficiency and user convenience to find out whether buildings claimed to be intelligent meet the intelligence requirements or not. v After conducting a literature survey to identify main intelligence characteristics, two buildings both claimed to be intelligent and able to provide occupants with healthy, secure and comfortable space, were selected as the case studies. The intelligent building principals and specific design considerations together with efficient system integration and system requirements were examined in the case studies. It was concluded that, even though case studies were admired in terms of holding commercial value and applying new technologies but there existed a lack in either employing or incorporating that technologies to meet desired responsiveness and dynamism which, are main attributes of intelligent buildings.

Industrialized building emerged as a consequence of the need for the economical and rapid provision of healthy and safe living environments. In both Europe and developing countries, concrete panel systems were gradually established as the primary building prefabrication method. However, concrete panel buildings demonstrated in time resistance to change, lack of adaptability to diverse sites and contexts and inefficiency in the use of the relatively expensive cement and steel. Open systems offer an alternative direction to industrialization in construction. In open systems, the differentiation of permanent from non-permanent elements and the organization of only the permanent ones in the form of a rationalized structural system (characteristic of open systems}, allow for the variable position and material composition of all walls. Nevertheless, conventional frame systems are not easily adaptable to diverse sites, since structural interdependency of bays and the need for alignment of elements allow only limited variability of building form. The developed Slab-Column System, presented herein, is a rationalized structural system which goes a step beyond conventional frames. Besides offering the possibility for flexible and changeable divisions of its structural platforms, the system is adaptable to a diversity of site conditions, thus broadening the applicability of large-scale prefabrication.

Trees, when used as structural elements in their natural, round form, are up to five times stronger than the largest piece of dimensioned lumber they could yield. Additionally, these whole-timbers have a lower effective embodied carbon than any other structural material. When combined into efficient structural configurations and joined using specially-engineered connections, whole-timber has the potential to replace entire steel and concrete structural systems in large-scale buildings, bridges, and infrastructure. Whole-timber may be the most appropriate structural solution for a low-carbon and fully renewable future in both developed temperate regions and the developing Global South. To reduce barriers to adoption, including project complexity and cost, a standardized "kit of parts" in whole-timber is proposed. This thesis proposes new designs for the first and most important element of this kit: a structurally independent column in whole-timber. A 20' compound column in whole-timber is prototyped at full-scale. New, simple calculation methods are developed for estimating the buckling capacity of tapered timbers. Based on conservative assumptions, the embodied carbon of whole-timber column systems is shown to be between 30% and 70% lower than conventional steel systems.

.In 2015, the government of India launched the "Housing for All by 2022" initiative to build 20 million units of affordable urban housing for lower income groups. Thus far, they have built fewer than two million units. In India, it is estimated that material costs can constitute 60 to 80% of the total cost of residential construction. Nonetheless, their construction mimics the materially inefficient practices of developed countries, practices developed to reduce labor over material costs. As a result, prismatic beams and flat slabs are frequently used despite their structural inefficiency. In its current state, the construction industry is resource intensive and unsustainable. The mounting use of steel-reinforced concrete structures in Indian cities has also garnered concern for the environmental costs of construction; construction accounts for 22% of India's carbon emissions.
The impact of structural systems on a building's embodied energy are immediately apparent: cement and steel are responsible for nearly 90% of a multistory concrete frame building's total embodied energy, and at least 50% of that is in the horizontally-spanning elements alone. With no end to construction in sight, new practices are needed to curb the environmental and economic costs of India's construction. This thesis explores the design of materially efficient floor systems that can reduce the economic and environmental costs of construction. Utilizing computational structural design, this thesis presents several strategies for the structural optimization of one-way concrete floor systems. Designed for the constraints of India, the structural elements are optimized to reduce the necessary volume of concrete and steel while resisting the same loads of an equivalent solid prismatic beam or slab.
While structural optimization for material efficiency is not a new practice, it is technically challenging and often reserved for large-scale and exclusive architectural projects. Conversely, this research applies these principles to common residential construction.

This thesis presents new interactive computational analysis tools for masonry structures based on limit state analysis. Thrust lines are used to clearly visualize the forces within the masonry and to predict possible collapse modes. The models are interactive and parametric to explore the relation between the different geometrical parameters and the possible equilibrium conditions. Collapse mechanism analyses are determined by combining kinematics and statics. Complex three-dimensional problems are analyzed using the same methods. This thesis presents a series of analysis tools that are fast and easy to use, but at the same time rigorous and highly accurate.

Повний текст джерелаWhile microelectronics systems become more and more complex, test costs have increased in the same way. Last years have seen many works focused on test cost reduction by using test data compression. However these techniques only focus on individual digital circuits whose structural implementation (netlist) is fully known by the designer. Therefore, they are not suitable for the testing of cores of a complete system. The goal of this PhD work was to provide a new solution for test data compression of integrated circuits taking into account the paradigm of systems-on-chip (SoC) built from pre-synthesized functions (IPs or cores). Then two systems testing method using compression are proposed for two different system architectures. The first one concerns SoC with IEEE 1500 test architecture (with bus-based test access mechanism), the second one concerns NoC-based systems. Both techniques use test scheduling methods combined with test data compression for better exploration of the design space. The idea is to increase test parallelism with no hardware extra cost. Experimental results performed on system-on-chip benchmarks show that the use of test data compression leads to test time reduction of about 50% at system level

A strategic alliance has been one of the core methods for expanding the business of many corporations in terms of geographic presence, business domain, and technological scope. The strategic alliance includes many different types of partnerships, including licensing in and out, joint product development, minority equity investments, joint ventures, and mergers and acquisitions. These alliances involve many distinctive participants inside and outside a corporation and for this reason, the alliance-forging process and management tend to be quite complicated for systematic analysis. Therefore in this thesis I employ system architecture frameworks to analyze strategic alliances in a systematic way from a holistic viewpoint. I apply an object process methodology (OPM) to understand interactions among different participants during the process of forging alliances, analyze the upstream and downstream influences, and finally adopt a holistic framework to illustrate detailed interactions during the process. The alliance process basically consists of four distinctive phases: formulation, partner selection, negotiation, and management. Comparing the results with the DuPont case, I realized that the alliance management phase should be augmented for more comprehensive management. Strategic alliances and mergers and acquisitions are discussed in the corporate-level context. They have many driving forces in common at the level of corporate context, but in mergers and acquisitions the economic conditions are more critical components than others during a strategy- formulation phase.

Повний текст джерелаAmong the different strategies oriented to the noise and vibration control, due to their promising properties in terms of limited required power supply, broad band and no tuneable nature, semi-active switched shunt architectures have well done for themselves. The idea of using piezo transducers to convert mechanical into electrical energy and elaborating related signal within an external time variant electrical circuit, represents the inspiring principle of this type of control. A wide amount of efforts has been spent on the semi-active switched shunt control with specific interest in the “synchronised” one; theoretical, numerical, experimental investigations, proved in different ways pros and cons of applications generally confined to the vibration field, in the low frequency band. Also the idea of extending this control to acoustics has been taken into account: problems like the structure-borne sound have been dealt with, implementing switch logic onto piezo networks mounted on structural components. An interesting industrial application in the field of aeronautics and automotive in general, is the interior sound level reduction: in this case a distribution of piezoelectric transducers suitably collocated may lead to remarkable effects, without excessive power consumption. In the present work, a semi analytic approach aimed at estimating the effects on the reduction of pressure sound level by synchronised switched shunt logic, is described. The displacement field within a 1D longitudinal air column through a Fourier series ;expansion has been formalised by assigning a sinusoidal perturbation and fluid–structure interface condition on the left and right boundaries, respectively. At first, a validation procedure has been implemented: both the convergence of the series coefficients and the satisfaction of boundary and initial conditions have been verified. To simulate the no control operative condition, the solution has been computed for the entire time domain, keeping invariant all circuitry properties; then for the switch working modality, solution has been computed by splitting the entire time domain into partitions, each one delimited by the instants at which the circuit is switched on (i. E. , by maxima and minima of the displacement on the right boundary domain); for any partition, specific circuitry properties (e. G. Piezo voltage, electrical field…) have been selected. Based on displacement information, related sound pressure level has been compared for no controlled and controlled operative conditions, with and without signal amplification

Analysis of product and organisational architecture using dependency structure matrices to describe a series of domains, in conjunction with real options theory, assists in predicting the strategic capabilities of either existing or potential products and organisations, and likely optimal or maximal rates of change. This assists in predicting the extent to which technologically dependent organisations can realistically create and capture value from a portfolio approach as a number of technology conglomerates currently seek to do. It also goes some way towards explaining why existing organisations find it difficult to create or exploit new knowledge and thereby helps explain why many synergies remain unrealised. This suggests that strategic leadership of technology conglomerates must be by people who possess either the tacit knowledge of the financial, organisational and technical aspects of the business, or who possess explicit tools to bridge any gaps. Given that explicit financial tools are available, in the absence of unique individuals the strategic planning process needs to incorporate measures designed to a priori check that the proposed strategies will result in technical knowledge creation and organisational value capture.

Повний текст джерелаStrukturen som system och program designas efter är väldigt viktigt. När en arbetar med mindre grupper av system så kommer den valda arkitekturen inte att påverka prestandan mycket. Men när dessa system växter i storlek och komplexitet så kommer valet av arkitektur vara väldigt viktigt. Problem som kan uppstå när mjukvarukomplexiteten ökar är väntandet på dataaccesser, långa sekventiella exekveringar och potentiell förlust av data. Det finns ingen optimal mjukvaruarkitektur, det finns oräkneligt många sätt att designa program. Det är intressant att kolla på vilka arkitekturer som preseterar bäst sätt till exekveringstid när en hanterar ett flertal större system och stora mängder data. I den här avhandlingen kommer ett fall, kallat "Ingångsavdraget", att implementeras i en monolitisk och en event-driven arkitekturell stil och sedan köras igenom tre olika scenarion. Den monolitiska arkitekturen var vald på grund av dess enkelhet och populäritet vid utveckling av enklar program och system. Den event-drivna arkitekturen valdes på grund av vissa teoretiska fördelar, så som att kunna undvika sekventiell kommunikation mellan systemen och därmed reducera tiden som systemen väntar på svar från varandra. Den huvudsakliga forskningsfrågan som ska besvaras är vad de största fördelarna och nackdelarna är när man bygger större system med en event-driven arkitekturell stil. Andra forskningsfrågor inkludera hur arkitekturen påverkar effektiviteten hos en organisation och samarbetet mellan olika team, samt hur datasäkerheten hanteras. De två implementationerna sattes igång tre olika scenarion inom fallet, där exekveringstid, antal HTTP-anrop skickade, databasaccesser och event skickad mättes. Resultaten visar att den event-drivna arkitekturen presterade 9.4% långsamare i det första scenariot och 0.5% långsamare i det andra scenariot. I det tredje scenariot presterade den event-drivna lösningen 49.0% snabbare än den monolitiska lösningen och avslutade därmed scenariot under hälften av tiden. Den monolitiska implementationen presterade generellt väl under de simplare scenarion 1 och 2, där systemen hade färre integrationer till varandra. I dessa fallen så är den den föredragna lösningen eftersom det är lättare att designa och implementera. Den event-drivna lösningen presterade mycket bättre i det mer komplexa scenario 3, där många system och integrationer var inblandade, eftersom den kunde ta bort vissa kopplingar mellan system. Slutligen så diskuteras även hållbarhet och etik i studien, samt begränsningarna av forskningen och potentiellt framtida arbete.

Diversos trabalhos na área de redes dinâmicas têm sido propostos na literatura com o objetivo de prover à arquitetura da Internet o suporte à mobilidade. O problema dessas redes instáveis na Internet consiste em oferecer um conjunto de mecanismo, tais como endereçamento, gerenciamento da informação e encaminhamento da informação, que suportem informação e entidade (Sistema Autônomo, Provedor de Serviços na Internet e Clientes) móveis. Nesse contexto, alguns trabalhos para arquitetura da Internet têm proposto uma maneira de separar a localização (atualmente o IP) e o nome identificador, devido ao forte relacionamento entre o IP e o nome. Em geral, eles propõem uma abordagem de roteamento na camada overlay para separar essas informações. Outros trabalhos acreditam que este desacoplamento não é suficiente para solucionar os problemas de mobilidade, desde que a dinamicidade gera muitas mensagens de controle e atualizações do vínculo entre o IP e o nome. Por essa razão, os pesquisadores também têm proposto novos modelos para gerenciar a camada overlay. Uma das contribuições deste trabalho é a proposta de uma solução para arquitetura da Internet denominada Stable Society que adota a abordagem de papéis. Um papel é uma unidade funcional que é utilizada para organizar a comunicação. Um importante diferencial da proposta é que além de desvincular o nome e a localização, ela também oferece soluções para os problemas relacionados a estruturação e manutenção da camada overlay. Além disso, este trabalho define quatro papéis: o mensageiro encaminha os dados dentro da sociedade; o guarda é a entidade mais estável para encaminhar mensagens entre as sociedades; o operário armazena informações; e o líder estrutura e gerencia a rede overlay. Reduzindo o escopo para a implementação desta dissertação de mestrado, o mensageiro e o guarda foram considerados como a camada de rede sem distinção de estabilidade, desde que o fornecimento de um mecanismo de gerenciamento do overlay de roteamento foi o objetivo do trabalho. Portanto, como prova do conceito apresentado pela proposta, os líderes e operários foram implementados, porque eles agem de maneira independente de tecnologia de acesso e são fundamentais para solucionar o problema da instabilidade nos processos de armazenamento e descoberta da informação. Como resultado, um novo algoritmo denominado Stable Society model over Distributes Hash Table (SSDHT) foi proposto. Além disso, este algoritmo foi comparado com outras soluções DHT (Chord). Os resultados mostraram que o SSDHT é um bom algoritmo, principalmente quando se aumenta a instabilidade (carga do tráfego, grau de mobilidade e tamanho da rede). Por exemplo, a taxa de mensagens entregue com sucesso foi acima de 90% quando a carga de tráfego, o grau de mobilidade e o tamanho da rede foram variados

Повний текст джерелаThe structural architecture and evolution of the Pyrenean-Alpine foreland of Provence are controlled by deep-seated basement faults inherited from Gondwana rifting during Permo-Triassic time, by variations in the Mesozoic sedimentary pile thickness and by alternating compressive and extensive tectonic events that affected the area since the late Paleozoic. The construction of two balanced cross sections at regional scale (~150 km) shows that the structural style of the Provence foreland is dominated by thick-skinned tectonic in eastern Provence and thin-skinned tectonic in western Provence, associated with diapirism in each domain. Both domains are coupled at crustal scale and separated by an accommodation zone in the cover: the Middle Durance Fault, whose deep-seated part is inherited from the Paleozoic. The current structure of the Pyrenean-Alpine foreland of Provence mainly corresponds to the Pyrenean-Provence compression signature during Late Cretaceous to Eocene (>90%). The Alpine deformation proportion is minor (9%). The Oligocene extension phase between these two compressive periods has been quantified at 1.7%. The apatite fission track data suggests an exhumation stage around 80 Ma related to the Pyrenean compression. The main Pyrenean thrusts were synchronous, as indicated by the age and distribution of syntectonic sedimentary series

The problem of creating generative music systems has been approached in different ways, each guided by different goals, aesthetics, beliefs and biases. These generative systems can be divided into two categories: the first is an ad hoc definition of the generative algorithms, the second is based on the idea of modeling and generalizing from preexistent music for the subsequent generation of new pieces. Most inductive models developed in the past have been probabilistic, while the majority of the deductive approaches have been rule based, some of them with very strong assumptions about music. In addition, almost all models have been discrete, most probably influenced by the discontinuous nature of traditional music notation. We approach the problem of inductive modeling of high level musical structures from a dynamical systems and signal processing perspective, focusing on motion per se independently of particular musical systems or styles. The point of departure is the construction of a state space that represents geometrically the motion characteristics of music. We address ways in which this state space can be modeled deterministically, as well as ways in which it can be transformed to generate new musical structures. Thus, in contrast to previous approaches to inductive music structure modeling, our models are continuous and mainly deterministic.
(cont.) We also address the problem of extracting a hierarchical representation of music from the state space and how a hierarchical decomposition can become a second source of generalization.

Повний текст джерелаBiological modeling, particularly of plant growth and functioning, is a rapidly expanding field that is useful in addressing climate change and food security issues at the global level. Modeling and simulation are essential tools for understanding the complex relationships between plant architecture and the processes that influence their growth in a changing environment.For plant modeling, a large number of formalisms have been developed in many disciplines and at different scales of representation.The objective of this thesis is to define a modular architecture that allows to simulate structural-functional plant systems by reusing and assembling different existing models.We will first study the different approaches to software reuse proposed by Krueger, then blackboard systems, and scientific workflow systems.These different approaches are used to cooperate, reuse and assemble software artifacts in a modular manner.Based on the observation that these systems provide the abstractions necessary for the integration of various artifacts, our working hypothesis is that a hybrid architecture, based on blackboard systems with dataflow-driven procedural control, would both achieve modularity while allowing the modeler to maintain control over execution.In Chapter 2, we describe the OpenAlea platform, a platform with software components and a scientific workflow system, allowing the assembly and composition of models through a visual programming interface. In Chapter 3, we propose a data structure for the blackboard, combining a topological representation of plant architecture at different scales, the Multiscale Tree Graph, and its geometric spatialization using the 3D PlantGL library. In chapter 4, we present the lambda-dataflows, an extension of dataflows allowing to couple simulation and analysis.Then, in Chapter 5, we present a first application, which illustrates the use of a generic gramineous leaf model in different plant models. Finally, in Chapter 6, we present all the architectural elements used to develop a generic framework for modelling the development of foliar diseases in an architectural canopy.The architecture presented in this thesis and its implementation in OpenAlea are a first step towards the realization of open integrative modeling platforms, allowing the cooperation of heterogeneous models in biology. The use of scientific workflow formalism in analysis and simulation makes it possible to consider in the short term the development of collaborative and distributed simulation platforms on a large scale

Повний текст джерелаThis thesis aims at designing a computer system enabling the computation of musical structures, their presentation/handling on a compositional side, and their interactive rendering. It is a study at the crossroads between several computer science research fields : discrete systems modeling, scheduling, software design and human-computer interfaces. We propose an architecture where program editing can affect their outputs, including during the rendering phase, while preserving the compositional benefits of a deferred-time approach. Compositions are therefore considered as continually running programs, where computation and rendering mechanisms are interleaved. We introduce new tools and interfaces to arrange their execution through time thanks to dynamic temporal scenario scripting, which we call meta-composing. The different results described in this manuscript are implemented in the computer-aided composition environment OpenMusic
