L'objectif de cette thèse est d'optimiser l'utilisation d'actionneurs redondants pour un avion de transport lorsqu'une défaillance des actionneurs arrive en vol. La tolérance aux pannes résulte ici de la redondance des actionneurs présents sur l'avion. Différents concepts et méthodes classiques liés aux chaînes de commande de vol tolérantes aux pannes sont d'abord examinés et de nouveaux concepts utiles pour l'analyse requise sont introduits. Le problème qui est abordé ici est de développer une méthode de gestion des pannes des commandes de vol dans le cas d'une défaillance partielle des actionneurs, qui va permettre à l'avion de poursuivre en toute sécurité la manœuvre prévue. Une approche de commande en deux étapes est proposée et appliquée à la fois à l'évaluation de la manœuvrabilité restante et à la conception de structures de commande tolérante aux pannes. Dans le premier cas, une méthode d'évaluation hors ligne des qualités de vol basée sur la commande prédictive est proposée. Dans le second cas, une structure de commande tolérante aux pannes basée sur la commande non linéaire inverse et la réaffectation des actionneurs en ligne est développée. Dans les deux cas, un problème de programmation linéaire quadratique (LQ) est formulé. Différents cas de pannes sont considérés lorsqu'un avion effectue une manœuvre classique. Trois solveurs numériques sont appliqués aux solutions en ligne et hors ligne des problèmes LQ qui en résultent.

Full textAbstract:
The selection of right process, use of optimal machining parameters and specification of best tolerance parameters have been recognized by industry as key issues to ensure product quality and reduce production cost. The three issues have thus attracted a great deal of attention over last several decades. However, they are often addressed separately in existing publications. In reality, the three issues are closely interrelated. Analyzing the three issues in isolation will inevitably lead to inconsistent, infeasible, or conflicting decisions. To avoid the drawbacks, an integrated approach is proposed to jointly solve process selection, machining parameter optimization, and tolerance design problems. The integrated problem is formulated as a bi-criterion model to handle both tangible and intangible costs. The model is solved using a modified Chebyshev goal programming method to achieve a preferred compromise between the two conflicting criteria.
The application of the proposed bi-criterion approach has been demonstrated by first using the single component single part feature case. The integrated approach is then extended to the multiple components multiple part features case (the assembly case).
Examples are provided to illustrate the application of the two models and the solution procedure. The results have shown that the decisions on process selection, machining parameter selection and tolerance design can be made simultaneously using the models.

Tesis para optar al grado de Doctor en FilosofíaLa construcción de las sociedades post-coloniales en América Latina ha tenido como desafío importante la persistencia de la idea de respeto y la lucha por la convivencia pacífica. Sin embargo, en la práctica, las tensiones y conflictos interculturales cada vez más crecientes constituyen un signo preocupante de los tiempos actuales. Estas tensiones se han generado, en gran parte, por el aparente fracaso de los procesos de modernización de aquellas sociedades (Tubino, 2004). La modernización fracasa en América Latina porque, entre otras razones, en lugar de enraizarse en las tradiciones culturales de los pueblos y recrearse desde ellas, les niega validez y las coloca como resistencias u obstáculos para el progreso 14 social del nuevo orden homogéneo (Tubino, 2004). En otras palabras se les da el estatuto del sexto del cuento de Kafka y por lo tanto del daño.

Full textAbstract:
Wireless sensor networks (WSNs) have recently achieved a great deal of attention due to its numerous attractive applications in many different fields. Sensors and WSNs possesses a number of special characteristics that make them very promising in many applications, but also put on them lots of constraints that make issues in sensor network particularly difficult. These issues may include topology control, routing, coverage, security, and data management. In this thesis, we focus our attention on the coverage problem. Firstly, we define the Sensor Energy-efficient Scheduling for k-coverage (SESK) problem. We then solve it by proposing a novel, completely localized and distributed scheduling approach, naming Distributed Energy-efficient Scheduling for k-coverage (DESK) such that the energy consumption among all the sensors is balanced, and the network lifetime is maximized while still satisfying the k-coverage requirement. Finally, in related work section we conduct an extensive survey of the existing work in literature that focuses on with the coverage problem.

Cette thèse se situe à l’intersection de deux domaines de recherche scientifique la Reconnaissance d’Objets Structurels (ROS) et la Recherche Opérationnelle (RO). Le premier consiste à rendre la machine plus intelligente et à reconnaître les objets, en particulier ceux basés sur les graphes. Alors que le second se focalise sur la résolution de problèmes d’optimisation combinatoire difficiles. L’idée principale de cette thèse est de combiner les connaissances de ces deux domaines. Parmi les problèmes difficiles existants en ROS, le problème de la distance d’édition entre graphes (DEG) a été sélectionné comme le cœur de ce travail. Les contributions portent sur la conception de méthodes adoptées du domaine RO pour la résolution du problème de DEG. Explicitement, des nouveaux modèles linéaires en nombre entiers et des matheuristiques ont été développé à cet effet et de très bons résultats ont été obtenus par rapport à des approches existantesThis thesis is focused on Graph Matching (GM) problems and in particular the Graph Edit Distance (GED) problems. There is a growing interest in these problems due to their numerous applications in different research domains, e.g. biology, chemistry, computer vision, etc. However, these problems are known to be complex and hard to solve, as the GED is a NP-hard problem. The main objectives sought in this thesis, are to develop methods for solving GED problems to optimality and/or heuristically. Operations Research (OR) field offers a wide range of exact and heuristic algorithms that have accomplished very good results when solving optimization problems. So, basically all the contributions presented in thesis are methods inspired from OR field. The exact methods are designed based on deep analysis and understanding of the problem, and are presented as Mixed Integer Linear Program (MILP) formulations. The proposed heuristic approaches are adapted versions of existing MILP-based heuristics (also known as matheuristics), by considering problem-dependent information to improve their performances and accuracy

Full textAbstract:
Node scheduling is one of the most effective techniques to maximize the lifetime of a wireless sensor network. It is the process of selecting a subset of nodes to monitor the sensor field on behalf of redundant nodes. At every round of the scheduling a small group of nodes are active while the rest of the sensor nodes are in sleep mode. In this thesis, we propose a novel node scheduling solution for wireless sensor networks. The main characteristic of our approach is its independence from location information as well as distance information. Moreover, it does not rely on unrealistic circular radio propagation models. In order to have a comprehensive solution, we have considered different relations between sensing range and transmission range. When these ranges are equal in addition to the case that transmission range is higher than sensing range, we devise a node scheduling scheme based on the concept of Minimum Dominating Set. Two heuristics are presented to determine a collection of minimum dominating sets of the graph of the wireless sensor network. At each round of the scheduling only one set is active. Minimum dominating sets are scheduled to be rotated periodically. Moreover, every set is synchronized prior to the end of its active period in order to minimize the effect of clock drift of sensor nodes. Two components are considered to address node failures during the on-duty period of minimum dominating sets. These are probing environment and adaptive sleeping. The former is responsible for probing the working nodes of the active set to detect any node failure. The latter adjusts the frequency of probing for minimizing the overhead of probing while preserving an adequate level of robustness for discovery of node failure. This framework is based on the PEAS protocol that has been developed by Fan Ye et al. [98, 99]. We propose a different node scheduling scheme with a three-tier architecture for the case that sensing range is higher than transmission range. The coverage tier includes a set of nodes to monitor the region of the interest. We propose a heuristic to determine a collection of d-dominating sets of the graph of the wireless sensor network. At every round of the scheduling one d-dominating set forms the coverage tier. Connectivity tier consists of sensor nodes that relay the data collected at the coverage tier back to the base station. Finally, the coverage management tier is responsible for managing different patterns of coverage such as cyclic or uniform coverage.

Full textAbstract:
The Will County community supports community policing efforts and wants their law enforcement agencies to be transparent, service-orientated, and committed to their diverse neighborhoods. The purpose of this phenomenological study was to explore current policing methods and tactics to improve community relationships within Will County, Illinois. Six different focus group studies were completed where 33 participants completed questionnaires and follow-up, in-depth interviews were conducted to gather data on personal police experiences and perceptions. The questionnaire responses were separated into three categories including Likert-scale response questions, dichotomous (yes and no answers), and ranking police tactics by levels of importance. Nine statistically data driven tables were generated into percentage totals that created comparisons of police methods, police tactics, and issues. The main policing tactics that Will County residents expected from their policing agencies were rapid response for service and police professionalism (appearance, conduct, communication skills). The participants expected that police agencies solve major crimes (high-profile murders, assaults, robberies). The lowest ranked police tactics discovered in all 4 subcategories surveyed were aggressive enforcement efforts (even for minor offenses) and traffic enforcement. The participants demonstrated support for community policing efforts that requires law enforcement agencies to work with their neighborhoods. The results of this study can be used to create a policing culture that incorporates traditional policing efforts and combines these efforts with the newer community policing methods that are positively impacting the Will County communities.

Wireless sensor networks (WSNs) have recently attracted a great deal of attention due to their numerous attractive applications in many different fields. Sensors and WSNs possess a number of special characteristics that make them very promising in a wide range of applications, but they also put on them lots of constraints that make issues in sensor network particularly challenging. These issues may include topology control, routing, coverage, security, data management and many others. Among them, coverage problem is one of the most fundamental ones for which a WSN has to watch over the environment such as a forest (area coverage) or set of subjects such as collection of precious renaissance paintings (target of point coverage) in order for the network to be able to collect environment parameters, and maybe further monitor the environment. In this dissertation, we highly focus on the area coverage problem. With no assumption of sensors’ locations (i.e., the sensor network is randomly deployed), we only consider distributed and parallel scheduling methods with the ultimate objective of maximizing network lifetime. Additionally, the proposed solutions (including algorithms, a scheme, and a framework) have to be energy-efficient. Generally, we investigate numerous generalizations and variants of the basic coverage problem. Those problems of interest include k-coverage, composite event detection, partial coverage, and coverage for adjustable sensing range network. Various proposed algorithms. In addition, a scheme and a framework are also suggested to solve those problems. The scheme, which is designed for emergency alarming applications, specifies the guidelines for data and communication patterns that significantly reduce the energy consumption and guarantee very low notification delay. For partial coverage problem, we propose a universal framework (consisting of four strategies) which can take almost any complete-coverage algorithm as an input to generate an algorithm for partial coverage. Among the four strategies, two pairs of strategies are trade-off in terms of network lifetime and coverage uniformity. Extensive simulations are conducted to validate the efficiency of each of our proposed solutions.

I detta arbete har läroplanens två inledande kapitel samt kursplaner i svenska och svenska som andraspråk för år 1-6 fokuserats. Utifrån poststrukturella grundantaganden om språkets konstituerande funktion för den sociala verkligheten samt postkoloniala teorier om andrafiering, analyseras kulturbegreppets olika skepnader och sammanhang i materialet för att få syn på undersökningsobjektets förhållande till en sådan ”vi” och ”dom”-diskurs. Med hjälp av Carol Bacchis (2009) metodologiska grepp på poststrukturell policyanalys, kallat WPR – What's the Problem Represented to be?, pekar uppsatsen på hur begreppet kultur framförallt används i termer av etnicitet och kulturell bakgrund, samtidigt som kulturell mångfald används som problemframställning i de undersökta texterna. Vidare kretsar analysen kring vilka essentialistiska och andrafierande förgivettaganden rörande kultur, identitet och fostran problemframställningen vilar på samt hur denna diskurs även kommer till uttryck i kursplanerna för svenska och svenska som andraspråk.

Full textAbstract:
Ce travail contribue à développer des méthodes de résolution associées à la méthode de simulation MMP (Model of Manufactured Part) développée par F.Vignat et F.Villeneuve. Le MMP est un modèle générique 3D des défauts géométriques engendrés sur les pièces fabriquées par un processus de fabrication donné. Ce modèle permet de générer un ensemble de pièces virtuellement fabriquées incluant les incertitudes de fabrication et permet par conséquent de mener l'analyse de tolérances fonctionnelles. Les méthodes de résolution développées autour du MMP permettent aux ingénieurs de fabrication d'évaluer une gamme de fabrication candidate du point de vue géométrique. Le développement des méthodes de résolution s'est effectué selon 2 axes. Le premier axe consiste à développer des méthodes pour la recherche du pire des cas (WCTA). La première approche de cet axe utilise des méthodes d'optimisation (SQP pour Sequential Quadratic Programming et GA pour les algorithmes génétiques) basées sur la recherche du pire des cas. La recherche du pire des cas consiste en un algorithme d'optimisation multicouche comportant deux boucles principales. La deuxième approche de cet axe consiste à faire une adaptation de la méthode du torseur des petits déplacements avec intervalle (modèle Jacobien Torseur développé au Canada) à la méthode MMP. Le deuxième axe concerne les méthodes stochastiques permettant une simulation de production d'un ensemble de pièces et l'analyse des résultats d'un point de vue statistique. La méthode stochastique est basée sur une méthode de tirage aléatoire sous contraintes. Les différentes approches sont finalement comparées entre elles.

Full textAbstract:
Divers domaines d'application des systèmes électroniques, comme par exemple les implants médicaux ou les puces cryptographiques pour les appareils portables, exigent à la fois une très faible puissance consommé et un niveau de fiabilité très élevé. De plus, comme la miniaturisation des technologies CMOS s'approche de ses limites ultimes, ces exigences deviennent nécessaires pour l'ensemble de l'industrie de microélectronique. En effet, en approchant ces limites les problèmes de la dissipation de puissance, du rendement de fabrication et de la fiabilité des composants empirent, rendant la poursuite de miniaturisation nanométriques de plus en plus difficile. Ainsi, avant que ces problèmes bloquent le progrès technologique, des nouvelles solutions au niveau du processus de fabrication et du design sont exigées pour maintenir la puissance dissipée, le rendement de fabrication et la fiabilité à des niveaux acceptables. Le projet de thèse vise le développement des architectures tolérantes aux fautes capables de répondre à ces défis pour les technologies de fabrication CMOS présentes et à venir. Ces architectures devraient permettre d'améliorer le rendement de fabrication et la fiabilité et de réduire en même temps la puissance dissipée des composants électroniques. Elles conduiraient en une innovation majeure, puisque les architectures tolérant aux fautes traditionnelles permettraient d'améliorer le rendement de fabrication et la fiabilité des composants électroniques aux dépens d'une pénalité significative en puissance consomméeVarious applications of electronic systems, such as medical implant devices, or cryptographic chips for potable devices require both lower power dissipation and higher level of reliability. Moreover, as silicon-based CMOS technologies are fast approaching their ultimate limits, these requirements become necessary for the entire microelectronics industry. Indeed, by approaching these limits, power dissipation, fabrication yield, and reliability worsen steadily making further nanometric scaling increasingly difficult. Thus, before reaching these limits, these problems could become show-stoppers unless new techniques are introduced to maintain acceptable levels of power dissipation, fabrication yield and reliability. This thesis aims to develop a fault tolerant architecture for logic designs that conciliates the above contradictory challenges and provides a global solution to the yield, reliability and power dissipation issues in current and future nanometric technologies. The proposed fault tolerant architecture is expected to improve the fabrication yield and reliability while reducing the power dissipation of electronic components. It leads a breakthrough, since traditional fault-tolerant architectures introduce significant area and power penalties

Comme la puissance de calcul des systèmes de calcul haute performance continue de croître, en utilisant un grand nombre de cœurs CPU ou d’unités de calcul spécialisées, les applications hautes performances destinées à la résolution des problèmes de très grande échelle sont de plus en plus sujettes à des pannes. En conséquence, la communauté de calcul haute performance a proposé de nombreuses contributions pour concevoir des applications tolérantes aux pannes. Cette étude porte sur une nouvelle classe d’algorithmes numériques de tolérance aux pannes au niveau de l’application qui ne nécessite pas de ressources supplémentaires, à savoir, des unités de calcul ou du temps de calcul additionnel, en l’absence de pannes. En supposant qu’un mécanisme distinct assure la détection des pannes, nous proposons des algorithmes numériques pour extraire des informations pertinentes à partir des données disponibles après une pannes. Après l’extraction de données, les données critiques manquantes sont régénérées grâce à des stratégies d’interpolation pour constituer des informations pertinentes pour redémarrer numériquement l’algorithme. Nous avons conçu ces méthodes appelées techniques d’Interpolation-restart pour des problèmes d’algèbre linéaire numérique tels que la résolution de systèmes linéaires ou des problèmes aux valeurs propres qui sont indispensables dans de nombreux noyaux scientifiques et applications d’ingénierie. La résolution de ces problèmes est souvent la partie dominante; en termes de temps de calcul, des applications scientifiques. Dans le cadre solveurs linéaires du sous-espace de Krylov, les entrées perdues de l’itération sont interpolées en utilisant les entrées disponibles sur les nœuds encore disponibles pour définir une nouvelle estimation de la solution initiale avant de redémarrer la méthode de Krylov. En particulier, nous considérons deux politiques d’interpolation qui préservent les propriétés numériques clés de solveurs linéaires bien connus, à savoir la décroissance monotone de la norme-A de l’erreur du gradient conjugué ou la décroissance monotone de la norme résiduelle de GMRES. Nous avons évalué l’impact du taux de pannes et l’impact de la quantité de données perdues sur la robustesse des stratégies de résilience conçues. Les expériences ont montré que nos stratégies numériques sont robustes même en présence de grandes fréquences de pannes, et de perte de grand volume de données. Dans le but de concevoir des solveurs résilients de résolution de problèmes aux valeurs propres, nous avons modifié les stratégies d’interpolation conçues pour les systèmes linéaires. Nous avons revisité les méthodes itératives de l’état de l’art pour la résolution des problèmes de valeurs propres creux à la lumière des stratégies d’Interpolation-restart. Pour chaque méthode considérée, nous avons adapté les stratégies d’Interpolation-restart pour régénérer autant d’informations spectrale que possible. Afin d’évaluer la performance de nos stratégies numériques, nous avons considéré un solveur parallèle hybride (direct/itérative) pleinement fonctionnel nommé MaPHyS pour la résolution des systèmes linéaires creux, et nous proposons des solutions numériques pour concevoir une version tolérante aux pannes du solveur. Le solveur étant hybride, nous nous concentrons dans cette étude sur l’étape de résolution itérative, qui est souvent l’étape dominante dans la pratique. Les solutions numériques proposées comportent deux volets. A chaque fois que cela est possible, nous exploitons la redondance de données entre les processus du solveur pour effectuer une régénération exacte des données en faisant des copies astucieuses dans les processus. D’autre part, les données perdues qui ne sont plus disponibles sur aucun processus sont régénérées grâce à un mécanisme d’interpolationAs the computational power of high performance computing (HPC) systems continues to increase by using huge number of cores or specialized processing units, HPC applications are increasingly prone to faults. This study covers a new class of numerical fault tolerance algorithms at application level that does not require extra resources, i.e., computational unit or computing time, when no fault occurs. Assuming that a separate mechanism ensures fault detection, we propose numerical algorithms to extract relevant information from available data after a fault. After data extraction, well chosen part of missing data is regenerated through interpolation strategies to constitute meaningful inputs to numerically restart the algorithm. We have designed these methods called Interpolation-restart techniques for numerical linear algebra problems such as the solution of linear systems or eigen-problems that are the inner most numerical kernels in many scientific and engineering applications and also often ones of the most time consuming parts. In the framework of Krylov subspace linear solvers the lost entries of the iterate are interpolated using the available entries on the still alive nodes to define a new initial guess before restarting the Krylov method. In particular, we consider two interpolation policies that preserve key numerical properties of well-known linear solvers, namely the monotony decrease of the A-norm of the error of the conjugate gradient or the residual norm decrease of GMRES. We assess the impact of the fault rate and the amount of lost data on the robustness of the resulting linear solvers.For eigensolvers, we revisited state-of-the-art methods for solving large sparse eigenvalue problems namely the Arnoldi methods, subspace iteration methods and the Jacobi-Davidson method, in the light of Interpolation-restart strategies. For each considered eigensolver, we adapted the Interpolation-restart strategies to regenerate as much spectral information as possible. Through intensive experiments, we illustrate the qualitative numerical behavior of the resulting schemes when the number of faults and the amount of lost data are varied; and we demonstrate that they exhibit a numerical robustness close to that of fault-free calculations. In order to assess the efficiency of our numerical strategies, we have consideredan actual fully-featured parallel sparse hybrid (direct/iterative) linear solver, MaPHyS, and we proposed numerical remedies to design a resilient version of the solver. The solver being hybrid, we focus in this study on the iterative solution step, which is often the dominant step in practice. The numerical remedies we propose are twofold. Whenever possible, we exploit the natural data redundancy between processes from the solver toperform an exact recovery through clever copies over processes. Otherwise, data that has been lost and is not available anymore on any process is recovered through Interpolationrestart strategies. These numerical remedies have been implemented in the MaPHyS parallel solver so that we can assess their efficiency on a large number of processing units (up to 12; 288 CPU cores) for solving large-scale real-life problems

Un système de systèmes est un système dont les composants sont eux-mêmes des systèmes indépendants, tous communiquant pour atteindre un objectif commun. Lorsque ces systèmes sont mobiles, il peut être difficile d'établir des connexions de bout-en-bout. L'architecture mise en place dans de telles situations est appelée réseau tolérant aux délais. Les données sont transmises d'un système à l'autre – selon les opportunités de communication, appelées contacts, qui apparaissent lorsque deux systèmes sont proches – et disséminées dans l'ensemble du réseau avec l'espoir que chaque message atteigne sa destination. Si une donnée est trop volumineuse, elle est découpée. Chaque fragment est alors transmis séparément.Nous supposons ici que la séquence des contacts est connue. On s'intéresse donc à des applications où la mobilité des systèmes est prédictible (les réseaux de satellites par exemple). Nous cherchons à exploiter cette connaissance pour acheminer efficacement des informations depuis leurs sources jusqu'à leurs destinataires. Nous devons répondre à la question : « Quels éléments de données doivent être transférés lors de chaque contact pour minimiser le temps de dissémination » ?Nous formalisons tout d'abord ce problème, appelé problème de dissémination, et montrons qu'il est NP-difficile au sens fort. Nous proposons ensuite des algorithmes pour le résoudre. Ces derniers reposent sur des règles de dominance, des procédures de prétraitement, la programmation linéaire en nombres entiers, et la programmation par contraintes. Une partie est dédiée à la recherche de solutions robustes. Enfin, nous rapportons des résultats numériques montrant l'efficacité de nos algorithmesSystems of systems are supersystems comprising elements which are themselves independent operational systems, all interacting to achieve a common goal. When the subsystems are mobile, these may suffer from a lack of continuous end-to-end connectivity. To address the technical issues in such networks, the common approach is termed delay-tolerant networking. Routing relies on a store-forward mechanism. Data are sent from one system to another – depending on the communication opportunities, termed contacts, that arise when two systems are close – and stored throughout the network in hope that all messages will reach their destination. If data are too large, these must be split. Each fragment is then transmitted separately.In this work, we assume that the sequence of contacts is known. Thus, we focus on applications where it is possible to make realistic predictions about system mobility (e.g. satellite networks). We study the problem of making the best use of knowledge about possibilities for communication when data need to be routed from a set of systems to another within a given time horizon. The fundamental question is: "Which elements of the information should be transferred during each contact so that the dissemination length is minimized"?We first formalize the so-called dissemination problem, and prove this is strongly NP-Hard. We then propose algorithms to solve it. These relies on different dominance rules, preprocessing procedures, integer-linear programming, and constraint programming. A chapter is dedicated to the search for robust solutions. Finally experimental results are reported to show the efficiency of our algorithms in practice

Due to the rapid development of technology and the rise of industry and economics, the damage to the society caused by the failure of power system becomes larger and larger. How to recover the power system from black-out in the shortest time with minimum cost has become an important issue in recent years. In this thesis, we will treat components of the power grid as intelligent agents, for instance, feeders, switches and power demand areas, and then construct a distributed power restoration system with intelligent agents based on concept of committee-based negotiation. Once the power system of an area fails, the system we proposed will automatically detect and isolate this area, and begin the solution finding processes. Base on the committee-based negotiation mechanism, the switch agents will share their information to the committee members of the committee which they belong to, negotiate with each other, and find out a candidate local solution depending on two major objective functions which are minimizing the number of switch changes and maximizing the amount of power demand to be restored. Finally, we can escape from being trapped in a local optimal solution and find the globally optimal solution with the hierarchical message passing and by the exhaustive constraint satisfaction decision making mechanism we proposed. Besides, we further take the problem of voltage drop into account and implement the mechanism of load-transfer to let the solution be much stable in practice. We also design a fault-tolerance mechanism on our restoration system to assure that our restoration system can work even when limited number of agents failed. Although the solution generated maybe degraded due to the missing of some information, but the system will not directly shut down and let the emergent problem of power system be unsolved. Otherwise, it must cause larger damage to the society. We will take different power grids and benchmark problems from power restoration research literatures as the test samples of our experiments and compare our multi-agent approach to the traditional methods. Besides, we also evaluate the fault tolerance ability of our restoration system to see how it performs under different degrees of failure in power restoration agents.

A traditional WSN is composed of several sensor nodes and a centralized sink. The sink analyzes data measured by the distributed sensor nodes and takes appropriate actions. A problem with this kind of architecture is that it may have a single-point of failure. Also, sensor nodes are not connected directly to the sink and must send data by hopping scheme through other sensor nodes. This means that it would take more time for the sink to collect data. Furthermore, in a WSN, faulty sensor nodes or noise may distort the message during transmission. An intruder may also alter the message maliciously. So far, there has been little research done on the design of robust WSN to overcome the single-point of failure problem and environmental interference. In this thesis, we propose a consensus problem algorithm based solution to enhance the accuracy of the detected result in an indoor autonomous local sensor network without a centralized sink. Under our scheme, there is no need to send the detected values to the sink. The solution can therefore reduce the transmission and routing time, allowing appropriate action to be made directly and quickly.

Graph mining has been applied to bioinformatics, chemistry, social network, and other applications for several years. Since real-world data are often accompanied with noise, fault-tolerant (FT) graph mining plays an important role for these applications. Mining quasi-clique is a special case of FT-graph mining for decades. However, few papers focus on more general case of fault-tolerant graph mining. In this thesis, we study the FT-graph mining problem. We purpose a simple algorithm and a path-based algorithm to find FT-maximal frequent subgraphs. Finally, some possible applications in this issue are discussed.

Composite tissue allotransplantation (CTA) is a new and rapidly developing frontier in reconstructive surgery. It involves the transplantation of functional anatomic units comprised of a variety of different tissues (e.g. face and hand transplant) from fresh cadavers to reconstruct complex defects. While current reconstructive surgical techniques using autologous tissue have provided patients with satisfactory results in most cases, there are a number of devastating injuries for which conventional techniques offer no adequate option. CTA is an attractive alternative for the reconstructive surgeon and may provide the patient with an ideal cosmetic and/or functional result without the morbidity of a donor site. Over the past two decades, progress in surgical techniques, medical and anesthesiologic treatment have led to substantially improved short-term outcomes after organ transplantation. Long-term results, however, have improved to a lesser degree and are limited by graft loss because of chronic rejection and by the side effects of non-specific lift-long immunosuppressive therapy. Modern transplant are limited by the shortage of donor organs, the side-effects of life-long immunosuppressive therapy, long-term cost of immunosuppressive drugs, and chronic rejection. CTA has remained controversial since its initial clinical application because of the requirement for lifelong immunosuppression, risk of rejection and infection, and ethical concerns. While there was significant doubt as to the longevity of composite tissue allotransplantation, currently, hand transplant patients on immunosuppressive regimens have a survival rate of 98% with acceptable function in the American-European series. At this time, the longest surviving hand transplant has been functioning well for over 10 years. CTA requires life-long nonspecific immunosuppression, which limit the widespread clinical application of CTA. Therefore, the creation of donor-specific tolerance to solve the problem of chronic rejection and side-effects of immunosuppression is one of our main goals for the immunological research. The induction and maintenance of immune tolerance to transplanted tissues constitute an active process involving multiple mechanisms that work cooperatively to prevent graft rejection. Various methods to induce donor-specific transplantation tolerance have been reported for experimental solid organs, composite tissue allotransplants and other allotransplants. The successful induction of donor specific tolerance might theoretically overcome the limitations. Over five decades, the induction of immune tolerance by the way of bone marrow stem cell to generate cell migration and mixed chimerism is the most mature and stable method to induce donor-specific tolerance. Chimerism refers to the harmonious coexistence of tissues from different animals of the same or different species in one organism. To determine a suitable formula of tolerance induction in the transplantation research is critical for clinical trials toward wider clinical application. There are several disadvantages of chimerism to induce tolerance. First, the anti-host reactive cells from the donor graft will cause graft-versus-host disease (GVHD). Second, there is 28-day delay to create tolerance to graft before CTA. It is not clinically applicable and feasible. Third, bone marrow cells require higher conditioning to indcue chimerism and tolerance in the large animal and human trials. Our goal is to minimize and free from life-long usage of the immunosuppresion. Our study concluded that vascularized bone marrow transplantation established by non-myeloablative conditioning can induce donor-specific tolerance for CTA in rat hindlimb model. The non-myeloablative strategy with anti-lymphoctye serum (ALS) and tacrolimus can further reduce the minimum total body irradiation (TBI) dose from 950 to 500 cGy and overcome the limitation of 28-day delay in the traditional BMT to generate the mixed chimerism and CTA tolerance. In addition, we compared the efficiency of tolerance induction of two commonly used drugs in the tranditional immunusppresion. Our findings suggested that utilization of cyclosporine in the non-myeloablative conditioning can reduce to 200 cGy of TBI to create tolerance. Our ultimate goal is to eliminate the TBI entirely and induce a high tolerance rate. Recently, we observed that manipulation of the recipient cell components responsible for alloreactivity would create a more tolerogenic milieu for bone marrow engraftment and encourage less toxic conditioning and high tolerance induction. These findings will develop a safe and robust method of tolerance induction to reduce rejection and maintain the graft survival and function. Our efforts have opened new doors to novel and less toxic antigen-specific approaches of conditioning recipients for engraftment of HSCs and adipose-derived mesenchymal stem cells (AD-MSCs) to optimize the application of reconstructive CTA with fewer ethical obstacles.

Given a graph G = (V, E) and a fault tolerant function f from V to N, a dominating set D(subset of V) is fault tolerant if | D∩N[v] | >= f(v) for all v in V. Given a graph G = (V, E) and a function g,from V to integers, the weight of g is defined as w(g) =Σ(v in V) g(v). For a vertex v in V, let g[v] =Σ(u in N[v]) g(u). A signed dominating function of G is a function g,from V to {-1,1}, such that g[v] >= 1 for all v in V. The signed domination number rs(G)(gamma_s(G)) of G is the minimum weight of a signed dominating function on G. We call a signed dominating function of a weight rs(G) as a rs-function of G. The signed domination problem is to find a rs-function of a graph. In this paper, we propose a new concept, fault tolerant domination. It is a generalization of some kinds of domination problems. Furthermore, we give an O(n + m) time algorithm to find a fault tolerant dominating set of minimum cardinality of a given strongly chordal graph G and a fault tolerant function f of G.

The purpose of the study is to explore the relations between junior high school students’ family atmosphere, frustration tolerance, and problem-solving attitude. The data were collected by paper-and-pencil questionnaire filled out by 503 students from 17 classes of Tainan City’s public schools. The study instrument includes “Family Atmosphere Scale”, “Frustration Tolerance Scale”, and “Problem-Solving Scale”. The data is analyzed with frequency distribution, percentage, mean, standard deviation, t-test, Pearson product moment correlation, one-way ANOVA, and stepwise multiple regression. The main discoveries of this study are as follows: 1.Junior high school students’ family atmosphere tends to be good and harmonious; their tolerance to schoolwork frustration is merely fair and to the interpersonal relationship frustration is medium high; their problem-solving attitude inclines to be positive. 2.Gender has a significant influence on problem recognition orientation—females score higher than males. Students from family of high social-economic status have more positive problem-solving attitude than those from family of low social-economic status. 3. There is positive correlation between family atmosphere, frustration tolerance, and problem-solving attitude. The result suggests that with more harmonious family atmosphere and higher frustration tolerance, students has more positive problem-solving attitude. 4. We can effectively predict junior high school students’ problem-solving attitude by their family atmosphere and frustration tolerance. Among the items in Frustration Tolerance Scale, the best predictive index is “Interpersonal Action Orientation”, which contributes to 51.9% of variance explained together with “Family Interaction” and “Schoolwork Action Orientation”. The discussion here is based on the results of the study mentioned above, and can be a reference for teenagers, parents and people who would have further study in this field.

Full textAbstract:
Code faults can seriously degrade scientific software accuracy. Therefore, it is imperative that scientific software developers scrutinize their codes in an attempt to find these faults. This thesis explores, particularly, the efficacy of code testing as a method of scientific software code fault detection.
Software engineers, as experts in code quality, have developed many code testing techniques, but many of these techniques cannot readily be applied to scientific codes for at least two reasons. First, scientific software testers do not usually have access to an ideal oracle. Second, scientific software outputs, by nature, can only be judged for accuracy and not correctness. Testing techniques developed under the assumption that these two problems can be ignored--as most have been--are of questionable value to computational scientists.
To demonstrate the reality of these problems and to provide an example of how software engineers and scientists can begin to address them, this thesis discusses the development and application of a novel technique: Mutation Sensitivity Testing (MST). MST is based on traditional mutation testing, but--in place of a focus on mutant "killing"--MST focuses on assessing the mutation sensitivity of a test set. In this thesis, MST experiments are conducted using eight small numerical routines, four classes of mutation operators, and 1155 tests. The results are discussed and some conclusions are drawn. Two observations are of particular interest to computational scientists. First, it is found that oracles that exhibit uncertainties greater than (approximately) 80% of the expected output are of questionable value when they are used in the testing of scientific software. Second, it is found that a small number
of carefully selected tests may be sufficient to falsify a code.Thesis (Master, Computing) -- Queen's University, 2009-04-19 13:34:08.943

This thesis covers three main issues in content delivery with a focus on placement algorithms of replica servers and replica contents. In a content delivery system, the location of replicas is very important as perceived by a quotation: Closer is better. However, considering the costs incurred by replication, it is a challenge to deploy replicas in a cost-effective manner. The objective of our work is to optimally select the location of replicas which includes sites for replica server deployment, servers for replica contents hosting, and en-route caches for object caching. Our solutions for corresponding applications are presented in three parts of the work, which makes significant contributions for designing scalable, reliable, and efficient systems for Internet content delivery. In the first part, we define the Fault-Tolerant Facility Allocation (FTFA) problem for the placement of replica servers, which relaxes the well known Fault-Tolerant Facility Location (FTFL) problem by allowing an integer (instead of binary) number of facilities per site. We show that the problem is NP-hard even for the metric version, where connection costs satisfy the triangle inequality. We propose two efficient algorithms for the metric FTFA problem with approximation factors 1.81 and 1.61 respectively, where the second algorithm is also shown to be (1.11,1.78)- and (1,2)-approximation through the proposed inverse dual fitting technique. The first bi-factor approximation result is further used to achieve a 1.52-approximation algorithm and the second one a 4-approximation algorithm for the metric Fault-Tolerant k-Facility Allocation problem, where an upper bound of facility number (i. e. k) applies. In the second part, we formulate the problem of QoS-aware content replication for parallel access in terms of combined download speed maximization, where each client has a given degree of parallel connections determined by its QoS requirement. The problem is further converted into the metric FTFL problem and we propose an approximation algorithm which is implemented in a distributed and asynchronous manner of communication. We show theoretically that the cost of our solution is no more than 2F* + RC*, where F* and C* are two components of any optimal solution while R is the maximum number of parallel connections. Numerical experiments show that the cost of our solutions is comparable (within 4% error) to the optimal solutions. In the third part, we establish mathematical formulation for the en-route web caching problem in a multi-server network that takes into account all requests (to any server) passing through the intermediate nodes on a request/response path. The problem is to cache the requested object optimally on the path so that the total system gain is maximized. We consider the unconstrained case and two QoS-constrained cases respectively, using efficient dynamic programming based methods. Simulation experiments show that our methods either yield a steady performance improvement (in the unconstrained case) or provide required QoS guarantees.http://proxy.library.adelaide.edu.au/login?url= http://library.adelaide.edu.au/cgi-bin/Pwebrecon.cgi?BBID=1461921

Hunger ist nach wie vor ein weit verbreitetes Problem. Nach der jüngsten Schätzung der FAO hungern weltweit noch immer über 800 Mio. Menschen. Prognosen gehen davon aus, dass die Agrarproduktion bis 2050 verdoppelt werden muss, um der steigenden Nachfrage nach Agrarprodukten durch Bevölkerungswachstum, Bioenergieproduktion und sich verändernde Ernährungsgewohnheiten zu begegnen.
Unter vielen Möglichkeiten, das Welternährungsproblem zu beschreiben, wird in dieser Dissertation das Konzept der Ernährungssicherheit nach der Definition der FAO herangezogen. Ernährungssicherheit umfasst als wichtigste Aspekte die Verfügbarkeit von Nahrungsmitteln und den ökonomischen Zugang zu Nahrungsmitteln. Nahrungsmittelverfügbarkeit ist in erster Linie von einer global ausreichenden Produktion abhängig, der Zugang zu Nahrung von der Kaufkraft der Haushalte. Die Kaufkraft wird sowohl durch das Einkommen wie auch die Agrarpreise beeinflusst.
Die Nahrungsmittelverfügbarkeit kann vor allem durch Ertragssteigerungen erhöht werden. Sollen die Ertragssteigerungen ressourcenschonend erfolgen, muss die Produktivität der Agrarproduktion bezogen auf alle Produktionsfaktoren inkl. Umweltgütern steigen. Nur durch technische und organisatorische Innovation kann dies realisiert werden. Ertragssteigerungen in Entwicklungsländern erhöhen gleichzeitig die Einkommen von potenziell von Hunger Betroffenen. Eine Begrenzung der Nachfrage nach Agrargütern kann global in erster Linie in den Bereichen Bioenergie und Konsum tierischer Produkte erfolgen.
Simulationen können helfen, den Einfluss einzelner Faktoren der globalen Nachfrage und des Angebots nach Agrarrohstoffen und -produkten auf die Welternährungslage genauer abzuschätzen. Ein Großteil der Simulationen in der Literatur kommt mithilfe von partiellen oder allgemeinen Gleichgewichtsmodellen zu Aussagen über gehandelte Mengen und Preise oder Wohlfahrtseffekte. In dieser Arbeit wird ein einfaches partielles Gleichgewichtsmodell für den Weltmarkt für Biotreibstoffe, Fleisch und Getreide entwickelt und mit der Methode der FAO zur Schätzung der Zahl der Hungernden gekoppelt. Dies ermöglicht die Abschätzung des Einflusses verschiedener Szenarien auf die Zahl der Hungernden. Für das Referenzjahr 2011 werden Szenarien alternativer Nachfrage nach Fleisch und Biotreibstoffen simuliert, ebenso wie ein Szenario alternativer landwirtschaftlicher Produktivität in der Europäischen Union.
Die Schätzungen ergeben einen signifikanten Einfluss der simulierten Nachfrage- und Angebotsverschiebungen. Im Vergleich mit dem Status Quo führt eine Reduktion des Fleischkonsums in den OECD-Ländern um 50% zu einer Reduktion der Zahl der Hungernden um 5%. Eine

Flächenproduktivität im Getreideanbau in der EU auf dem Niveau von 1980 steigert die Zahl der Hungernden um mehr als 5%, ein Anstieg der Biotreibstoffquote in der OECD auf 10% erhöht die Zahl der Hungernden gar um 10%.
Die Durchsetzung geeigneter politischer Maßnahmen zur Verbesserung der Welternährungslage kann durch eine breite öffentliche Unterstützung beschleunigt oder erst ermöglicht werden. Über die öffentliche Meinung zu Fragen der Welternährung in Deutschland existieren bisher keine expliziten Studien. In den Themenbereichen landwirtschaftliche Produktion und Nahrungsmittelkonsum stellt das Thema Welternährung nur einen Aspekt dar, der neben Fragen nach z.B. der Lebensmittelsicherheit und Gesundheit sowie den Auswirkungen von Agrarproduktion auf Landschaft und Umwelt steht.
Hier werden Ergebnisse einer Online-Befragung zum Thema Welternährung präsentiert, die im März 2012 mit einer repräsentativen Stichprobe 1.200 deutscher Internetnutzer durchgeführt wurde. Die Befragung beinhaltete im Wesentlichen die Bewertung der Wirkung verschiedener potenzieller Ursachen der weltweiten Unterernährung, sowie Maßnahmen und Entwicklungen zu ihrer Lösung. Die Ergebnisse zeigen, dass das Thema Welthunger in erster Linie mit Merkmalen akuter (Hunger-) Krisen in Verbindung gebracht wird. Die vielversprechendsten Lösungsmaßnahmen sind in den Augen der Befragten der Ausbau des Fairen Handels, Absatzmärkte für Kleinbauern sowie ein Lebensmittelspekulationsverbot. Der intensiven Landwirtschaft in der Welt wie auch in Europa sowie insbesondere der Grünen Gentechnik wird kein Potenzial zur Lösung des Problems zugesprochen. Die Antwortmuster lassen auf die Präsenz eines Halo-Effekts mit einer Übertragung unterstellter negativer Umweltwirkungen auf das Thema Welternährung schließen.
Die Grüne Gentechnik ist eine Agrartechnologie, die potenziell zur Angebotsausweitung von Agrarprodukten genauso beitragen kann wie zu einer ressourcenschonenderen Landwirtschaft. Bisherige Anwendungen, hauptsächlich Herbizidtoleranz sowie Insektenresistenz, haben u.a. zu einer Steigerung der effektiven Erträge, einer Einsparung von Insektiziden und einer Steigerung der Profite vor allem im Baumwollanbau beigetragen. Trotz zahlreicher Belege besteht über die Auswirkungen von gentechnisch veränderten (GV) Nutzpflanzen eine anhaltende Kontroverse. Ein Großteil der europäischen Bevölkerung lehnt den Anbau ebenso ab wie einen Verzehr von Produkten aus GV-Pflanzen. Unterstellte sozio-ökonomische Auswirkungen oder Auswirkungen auf die Welternährung sind nur zwei Determinanten von vielen, die zu den Einstellungen zur Grünen Gentechnik beitragen.
Zur Konsolidierung des Wissens im Bereich agronomischer sowie sozio-ökonomischer Auswirkungen von GV-Pflanzen wurde eine Meta-Analyse durchgeführt. In wissenschaftlichen Datenbanken wurden

147 Primärstudien identifiziert, die für die Meta-Analyse verwendet wurden. Die Analyse beschränkt sich auf gentechnisch veränderte Sojabohnen, Mais und Baumwolle.
Als mittlere Effekte des Anbaus von GV-Pflanzen ergibt die Meta-Analyse eine Steigerung des Ertrages um 22%, eine Reduktion der Menge der angewendeten Pflanzenschutzmittel um 37% und eine Steigerung der Profite der Bauern um 68%. Die Höhe der Effekte hängt stark von verschiedenen Faktoren ab. Die Effekte sind für alle drei genannten Variablen in Entwicklungsländern betragsmäßig größer als in Industrieländern. Auch sind die Effekte des Anbaus von GV-Pflanzen bei Erträgen und beim Pflanzenschutzmitteleinsatz betragsmäßig höher für insektenresistente Pflanzen als bei solchen mit Herbizidtoleranz.
Aus den in der Arbeit gewonnenen Erkenntnissen kann geschlussfolgert werden, dass sowohl das Nahrungsmittelangebot gesteigert als auch die Nachfrage begrenzt werden sollte. Dies verlangt eine standortangepasste Ausnutzung vorhandener und die Entwicklung neuer Technologien. Auch die Gentechnik kann einen Beitrag leisten. Der Kleinbauernsektor muss vordringlich gefördert werden. Zur Begrenzung der Nachfrage können neben der Politik, welche vor allem die Biotreibstoffnachfrage beeinflussen kann, auch Konsumenten durch Verzicht auf tierische Produkte beitragen. Dies wie auch die Durchführung effektiver politischer Maßnahmen sind auf eine unverzerrte Sichtweise der Öffentlichkeit auf das Thema Welternährung angewiesen. Dazu muss das Thema in Wissenschaftskommunikation und Bildung stärker thematisiert werden.
