Book excerpt: Les systèmes sur puces intègrent aujourd'hui sur le même substrat des parties analogiques et des unités de traitement numérique. Tandis que la complexité de ces systèmes s'accroissait, leur temps de mise sur le marché se réduisait. Une conception descendante globale et coordonnée du système est devenue indispensable de façon à tenir compte des interactions entre les parties analogiques et les partis numériques dès le début du développement. Dans le but de répondre à ce besoin, cette thèse expose un processus de raffinement progressif et méthodique des parties analogiques, comparable à ce qui existe pour le raffinement des parties numériques. L'attention a été plus particulièrement portée sur la définition des niveaux analogiques les plus abstraits et à la mise en correspondance des niveaux d'abstraction entre parties analogiques et numériques. La cohérence du raffinement analogique exige de détecter le niveau d'abstraction à partir duquel l'utilisation d'un modèle trop idéalisé conduit à des comportements irréalistes et par conséquent d'identifier l'étape du raffinement à partir de laquelle les limitations et les non linéarités aux conséquences les plus fortes sur le comportement doivent être introduites. Cette étape peut être d'un niveau d'abstraction élevé. Le choix du style de modélisation le mieux adapté à chaque niveau d'abstraction est crucial pour atteindre le meilleur compromis entre vitesse de simulation et précision. Les styles de modélisations possibles à chaque niveau ont été examinés de façon à évaluer leur impact sur la simulation. Les différents modèles de calcul de SystemC-AMS ont été catégorisés dans cet objectif. Les temps de simulation obtenus avec SystemC-AMS ont été comparés avec Matlab Simulink. L'interface entre les modèles issus de l'exploration d'architecture, encore assez abstraits, et les modèles plus fin requis pour l'implémentation, est une question qui reste entière. Une bibliothèque de composants électroniques complexes décrits en SystemC-AMS avec le modèle de calcul le plus précis (modélisation ELN) pourrait être une voie pour réussir une telle interface. Afin d'illustrer ce que pourrait être un élément d'une telle bibliothèque et ainsi démontrer la faisabilité du concept, un modèle d'amplificateur opérationnel a été élaboré de façon à être suffisamment détaillé pour prendre en compte la saturation de la tension de sortie et la vitesse de balayage finie, tout en gardant un niveau d'abstraction suffisamment élevé pour rester indépendant de toute hypothèse sur la structure interne de l'amplificateur ou la technologie à employer.

Available in PDF, EPUB and Kindle. Book excerpt: Il y a une tendance croissante à considérer les processus d'une organisation comme l'une de ses grandes forces. Les processus sont des ressources réutilisables d'une organisation qui définissent les procédures de travail pour la réalisation de ses objectifs. Avec l'importance croissante du secteur des logiciels et des services, la standardisation des processus devient indispensable pour maintenir sa crédibilité. Le développement de processus suit un cycle de vie très similaire à celui du développement logiciel. Par exemple, il se compose de plusieurs phases et suit une approche incrémentale qui mène à son amélioration continue. Cette approche incrémentale peut être complétée par une stratégie basée sur le raffinement pour développer, exécuter et maintenir les processus de développement de logiciels.Cette thèse propose une base conceptuelle pour le développement de processus logiciels par raffinement, sans perdre de vue les exigences spécifiques de chaque phase du cycle de vie d'un tel processus. Elle utilise l'ingénierie dirigée par les modèles pour présenter un ensemble de méta-modèles pour le développement de processus logiciels où chaque méta-modèle correspond à une phase différente d'un processus (spécification, implémentation et instanciation). Le modèle d'un processus traverse une série de raffinement jusqu'à ce qu'elle soit enrichie par des capacités d'exécution. Le développement d'un interpréteur permet d'exécuter ce modèle. Il donne la possibilité de relier les modèles des differentes phases par des liens de traçabilité. Les intervenants peuvent interagir avec le processus en exécution à l'aide d'une interface de supervision. Un niveau de variabilité incluse dans les modèles de processus permet leur adaptation pendant l'exécution. Tout en prenant en compte la nécessité de se conformer aux standards adoptés par l'organisation, l'architecture de l'approche de modélisation proposée exploite le concept d'abstraction en s'inspirant de la notion de composant logiciel pour aider à la réutilisation de modèles de processus. Notre méthode est également prévue pour les entreprises qui veulent suivre plusieurs standards pour le même projet.Sur la base des connaissances acquises grâce à l'étude des langages de modélisation actuels du domaine, le cadre proposé pour la modélisation de processus présente une architecture qui se développe autour des concepts de «conception par contrat» et «conception pour et par la réutilisation». Ceci permet de construire un modèle de processus qui a une structure modulaire et garantit la correction des interactions entre des activités constituantes. Afin de favoriser la séparation des préoccupations, les flux de données au sein d'un processus sont gérés à un niveau d'abstraction différent de celui des flux de contrôle. La conformité entre ces deux niveaux permet d'offrir une architecture bicouche. Le flux de données lors de l'exécution est assuré par un système de gestion d'événements. Une évaluation des capacités de l'approche proposée est fournie par une analyse basée sur l'ensemble des «workflow patterns». Cela permet une comparaison directe de ses capacités avec d'autres approches de modélisation de processus

Available in PDF, EPUB and Kindle. Book excerpt: The use of parallel programming and architectures is essential for simulating and solving problems in modern computational practice. There has been rapid progress in microprocessor architecture, interconnection technology and software devel- ment, which are in?uencing directly the rapid growth of parallel and distributed computing. However, in order to make these bene?ts usable in practice, this dev- opment must be accompanied by progress in the design, analysis and application aspects of parallel algorithms. In particular, new approaches from parallel num- ics are important for solving complex computational problems on parallel and/or distributed systems. The contributions to this book are focused on topics most concerned in the trends of today’s parallel computing. These range from parallel algorithmics, progr- ming, tools, network computing to future parallel computing. Particular attention is paid to parallel numerics: linear algebra, differential equations, numerical integ- tion, number theory and their applications in computer simulations, which together form the kernel of the monograph. We expect that the book will be of interest to scientists working on parallel computing, doctoral students, teachers, engineers and mathematicians dealing with numerical applications and computer simulations of natural phenomena.

Book excerpt: Cultural critic Fredric Jameson, renowned for his incisive studies of the passage of modernism to postmodernism, returns to the movement that dramatically broke with all tradition in search of progress for the first time since his acclaimed A Singular Modernity . The Modernist Papers is a tour de froce of anlysis and criticism, in which Jameson brings his dynamic and acute thought to bear on the modernist literature of the nineteenth and twentieth centuries. Jameson discusses modernist poetics, including intensive discussions of the work of Baudelaire, Rimbaud, Mallarmé, Wallace Stevens, Joyce, Proust, and Thomas Mann. He explores the peculiarties of the American literary field, taking in William Carlos Williams and the American epic, and examines the language theories of Gertrude Stein. Refusing to see modernism as simply a Western phenomenon he also pays close attention to its Japanese expression; while the complexities of a late modernist representation of twentieth-century politics are articulated in a concluding section on Peter Weiss’s novel The Aesthetics of Resistance. Challenging our previous understanding of the literature of this pperiod, this monumental work will come to be regarded as the classic study of modernism.

Available in PDF, EPUB and Kindle. Book excerpt: The Violence of Modernity turns to Charles Baudelaire, one of the most canonical figures of literary modernism, in order to reclaim an aesthetic legacy for ethical inquiry and historical critique. Works of modern literature are commonly theorized as symptomatic responses to the trauma of history. In a climate that tends to privilege crisis over critique, Debarati Sanyal argues that it is urgent to rethink literary experience in terms that recall its contestatory potential. Examining Baudelaire's poems afresh, she shifts the focus of critical attention toward an account of modernism as an active engagement with violence, specifically the violence of history in nineteenth-century France. Sanyal analyzes a literary current that uses the traditional hallmarks of modernism—irony, intertextuality, self-reflexivity, and formalism—to challenge the historical violence of modernity. Baudelaire and the committed ironists writing in his wake teach us how to read and resist the violence of history, and thereby to challenge the melancholy tenor of our contemporary "wound culture." In a series of provocative readings, Sanyal presents Baudelaire's poetry as an aesthetic form that contests historical violence through rhetorical strategies of complicity, counterviolence, and critique. The book develops a new account of Baudelaire's significance as a modernist by dislodging him both from his traditional status as a practitioner of "art for art's sake" and from his more recent incarnation as the poet of trauma. Following her extended analysis of Baudelaire's poetry, Sanyal in later chapters considers a number of authors influenced by his strategies—including Rachilde, Virginie Despentes, Albert Camus, and Jean-Paul Sartre—to examine the relevance of their interventions for our current climate of trauma and terror. The result is a study that underscores how Baudelaire's legacy continues to energize literary engagements with the violence of modernity.

Available in PDF, EPUB and Kindle. Book excerpt: Numerical Methods for Partial Differential Equations: Finite Difference and Finite Volume Methods focuses on two popular deterministic methods for solving partial differential equations (PDEs), namely finite difference and finite volume methods. The solution of PDEs can be very challenging, depending on the type of equation, the number of independent variables, the boundary, and initial conditions, and other factors. These two methods have been traditionally used to solve problems involving fluid flow. For practical reasons, the finite element method, used more often for solving problems in solid mechanics, and covered extensively in various other texts, has been excluded. The book is intended for beginning graduate students and early career professionals, although advanced undergraduate students may find it equally useful. The material is meant to serve as a prerequisite for students who might go on to take additional courses in computational mechanics, computational fluid dynamics, or computational electromagnetics. The notations, language, and technical jargon used in the book can be easily understood by scientists and engineers who may not have had graduate-level applied mathematics or computer science courses. Presents one of the few available resources that comprehensively describes and demonstrates the finite volume method for unstructured mesh used frequently by practicing code developers in industry Includes step-by-step algorithms and code snippets in each chapter that enables the reader to make the transition from equations on the page to working codes Includes 51 worked out examples that comprehensively demonstrate important mathematical steps, algorithms, and coding practices required to numerically solve PDEs, as well as how to interpret the results from both physical and mathematic perspectives

Available in PDF, EPUB and Kindle. Book excerpt: The ten volumes of "Handbook of Pragmatics Highlights" focus on the most salient topics in the field of pragmatics, thus dividing its wide interdisciplinary spectrum in a transparent and manageable way. While the other volumes select specific philosophical, cognitive, grammatical, social, cultural, variational, or interactional angles, this 8th volume focuses on theories and phenomena at the level of discourse, but leaving aside conversational interaction. It provides the reader with pragmatics-oriented information on discourse analysis, critical discourse analysis and critical linguistics, as well as text linguistics and appraisal theory, while introducing other specific approaches to discourse through concepts such as polyphony, intertextuality, genre, and "enonciation." Furthermore, topics such as public discourse, narrative, figures of speech, cohesion and coherence, pragmatic markers, manipulation, and humor, are all dealt with in separate chapters. The binding idea, explained in the introduction, is that discursive pragmatics may serve as a platform for a diversity of perspectives on discourse, as they have emerged not only in the language sciences but also in the humanities and social sciences in general."

Available in PDF, EPUB and Kindle. Book excerpt: Five Faces of Modernity is a series of semantic and cultural biographies of words that have taken on special significance in the last century and a half or so: modernity, avant-garde, decadence, kitsch, and postmodernism. The concept of modernity--the notion that we, the living, are different and somehow superior to our predecessors and that our civilization is likely to be succeeded by one even superior to ours--is a relatively recent Western invention and one whose time may already have passed, if we believe its postmodern challengers. Calinescu documents the rise of cultural modernity and, in tracing the shifting senses of the five terms under scrutiny, illustrates the intricate value judgments, conflicting orientations, and intellectual paradoxes to which it has given rise. Five Faces of Modernity attempts to do for the foundations of the modernist critical lexicon what earlier terminological studies have done for such complex categories as classicism, baroque, romanticism, realism, or symbolism and thereby fill a gap in literary scholarship. On another, more ambitious level, Calinescu deals at length with the larger issues, dilemmas, ideological tensions, and perplexities brought about by the assertion of modernity.

Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this book is to provide an elementary yet systematic description of the Bogoliubov-de Gennes (BdG) equations, their unique symmetry properties and their relation to Green’s function theory. Specifically, it introduces readers to the supercell technique for the solutions of the BdG equations, as well as other related techniques for more rapidly solving the equations in practical applications. The BdG equations are derived from a microscopic model Hamiltonian with an effective pairing interaction and fully capture the local electronic structure through self-consistent solutions via exact diagonalization. This approach has been successfully generalized to study many aspects of conventional and unconventional superconductors with inhomogeneities – including defects, disorder or the presence of a magnetic field – and becomes an even more attractive choice when the first-principles information of a typical superconductor is incorporated via the construction of a low-energy tight-binding model. Further, the lattice BdG approach is essential when theoretical results for local electronic states around such defects are compared with the scanning tunneling microscopy measurements. Altogether, these lectures provide a timely primer for graduate students and non-specialist researchers, while also offering a useful reference guide for experts in the field.

Book excerpt: Advanced numerical simulations that use adaptive mesh refinement (AMR) methods have now become routine in engineering and science. Originally developed for computational fluid dynamics applications these methods have propagated to fields as diverse as astrophysics, climate modeling, combustion, biophysics and many others. The underlying physical models and equations used in these disciplines are rather different, yet algorithmic and implementation issues facing practitioners are often remarkably similar. Unfortunately, there has been little effort to review the advances and outstanding issues of adaptive mesh refinement methods across such a variety of fields. This book attempts to bridge this gap. The book presents a collection of papers by experts in the field of AMR who analyze past advances in the field and evaluate the current state of adaptive mesh refinement methods in scientific computing.
