This book was released on 1997 with total page 260 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cette thèse est une contribution à l'étude du placement dynamique de processus sur des machines multiprocesseurs à mémoire distribuée. Le contexte de notre travail est celui de la simulation et de l'évaluation de l'exécution d'applications dont le nombre de processus et le moment de leur création dépendent de l'exécution en cours. Nous proposons un nouvel algorithme évolutif de placement dynamique de processus de type approximatif, avec des éléments de contrôle et d'information distribués. A chaque noeud X d'une machine parallèle est associé un sous-ensemble de processeurs avec lesquels il peut partager sa charge de manière équitable. Ce sous-ensemble est appelé la Solution de Placement (SP) du noeud. La Solution de Placement initiale d'un noeud X est composée du sous-ensemble des noeuds directement connectés au noeud X. La décision de placement d'un processus est faite au moment de sa création, il peut alors être placé sur le noeud sur lequel il a été créé ou bien sur un des noeuds de sa SP. Sous l'effet de certains opérateurs (declin, croissance, fusion, remplacement, rotation) la Solution de Placement d'un noeud évolue au cours de l'exécution de l'application ce qui permet une répartition et un équilibrage des charges des noeuds. Pour étudier le comportement de l'algorithme évolutif, nous avons utilisé le simulateur séquentiel SIMAD qui est un outil conçu pour évaluer les algorithmes d'allocation dynamique de charge sur des machines MIMD à mémoire distribuée. Le deuxième apport de cette thèse est la définition et l'intégration dans SIMAD d'un langage synthétique qui permet de décrire des applications parallèles avec des graphes de communication généraux. Le document se termine par la présentation d'une partie des résultats de l'ensemble des expériences que nous avons menées, dans le but d'évaluer les performances et le comportement de notre approche du placement dynamique de processus. Deux types de résultats sont présentés et analysés. Tout d'abord nous recherchons l'influence de certains paramètres (la taille maximale des SP, l'actualisation des SP, le nombre de processus par niveau de charge et l'opérateur de fusion) sur le comportement de l'algorithme évolutif. Ensuite, une étude comparative avec d'autres méthodes de placement dynamique permet de mettre en évidence les performances de notre approche.

Download or read book Programming Environments for Massively Parallel Distributed Systems written by Karsten M. Decker and published by Birkhäuser. This book was released on 2013-04-17 with total page 417 pages. Available in PDF, EPUB and Kindle. Book excerpt: Massively Parallel Systems (MPSs) with their scalable computation and storage space promises are becoming increasingly important for high-performance computing. The growing acceptance of MPSs in academia is clearly apparent. However, in industrial companies, their usage remains low. The programming of MPSs is still the big obstacle, and solving this software problem is sometimes referred to as one of the most challenging tasks of the 1990's. The 1994 working conference on "Programming Environments for Massively Parallel Systems" was the latest event of the working group WG 10.3 of the International Federation for Information Processing (IFIP) in this field. It succeeded the 1992 conference in Edinburgh on "Programming Environments for Parallel Computing". The research and development work discussed at the conference addresses the entire spectrum of software problems including virtual machines which are less cumbersome to program; more convenient programming models; advanced programming languages, and especially more sophisticated programming tools; but also algorithms and applications.
Download or read book Alienation and Freedom written by Frantz Fanon and published by Bloomsbury Publishing. This book was released on 2018-04-19 with total page 816 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the publication of The Wretched of the Earth in 1961, Fanon's work has been deeply significant for generations of intellectuals and activists from the 60s to the present day. Alienation and Freedom collects together unpublished works comprising around half of his entire output – which were previously inaccessible or thought to be lost. This book introduces audiences to a new Fanon, a more personal Fanon and one whose literary and psychiatric works, in particular, take centre stage. These writings provide new depth and complexity to our understanding of Fanon's entire oeuvre revealing more of his powerful thinking about identity, race and activism which remain remarkably prescient. Shedding new light on the work of a major 20th-century philosopher, this disruptive and moving work will shape how we look at the world.
Download or read book The Rhetoric of Religion written by Kenneth Burke and published by Univ of California Press. This book was released on 1970-04 with total page 340 pages. Available in PDF, EPUB and Kindle. Book excerpt: "But the point of Burke's work, and the significance of his achievement, is not that he points out that religion and language affect each other, for this has been said before, but that he proceeds to demonstrate how this is so by reference to a specific symbolic context. After a discussion 'On Words and The Word,' he analysess verbal action in St. Augustine's Confessions. He then discusses the first three chapters of Genesis, and ends with a brilliant and profound 'Prologue in Heaven,' an imaginary dialogue between the Lord and Satan in which he proposes that we begin our study of human motives with complex theories of transcendence,' rather than with terminologies developed in the use of simplified laboratory equipment. . . . Burke now feels, after some forty years of search, that he has created a model of the symbolic act which breaks through the rigidities of the 'sacred-secular' dichotomy, and at the same time shows us how we get from secular and sacred realms of action over the bridge of language. . . . Religious systems are systems of action based on communication in society. They are great social dramas which are played out on earth before an ultimate audience, God. But where theology confronts the developed cosmological drama in the 'grand style,' that is, as a fully developed cosmological drama for its religious content, the 'logologer' can be further studied not directly as knowledge but as anecdotes that help reveal for us the quandaries of human governance." --Hugh Dalziel Duncan from Critical Responses to Kenneth Burke, 1924 - 1966, edited by William H. Rueckert (Minneapolis: University of Minnesota Press, 1969).
Download or read book Your Mindful Compass written by Andrea Maloney Schara and published by . This book was released on 2013-12-01 with total page 318 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Your Mindful Compass" takes us behind the emotional curtain to see the mechanisms regulating individuals in social systems. There is great comfort and wisdom in knowing we can increase our awareness to manage the swift and ancient mechanisms of social control. We can gain greater flexibility by seeing how social controls work in systems from ants to humans. To be less controlled by others, we learn how emotional systems influence our relationship-oriented brain. People want to know what goes on in families that give rise to amazing leaders and/or terrorists. For the first time in history we can understand the systems in which we live. The social sciences have been accumulating knowledge since the early fifties as to how we are regulated by others. S. Milgram, S. Ashe, P. Zimbardo and J. Calhoun, detail the vulnerability to being duped and deceived and the difficulty of cooperating when values differ. Murray Bowen, M.D., the first researcher to observe several live-in families, for up to three years, at the National Institute of Mental Health. Describing how family members overly influence one another and distribute stress unevenly, Bowen described both how symptoms and family leaders emerge in highly stressed families. Our brain is not organized to automatically perceive that each family has an emotional system, fine-tuned by evolution and "valuing" its survival as a whole, as much as the survival of any individual. It is easier to see this emotional system function in ants or mice but not in humans. The emotional system is organized to snooker us humans: encouraging us to take sides, run away from others, to pressure others, to get sick, to blame others, and to have great difficulty in seeing our part in problems. It is hard to see that we become anxious, stressed out and even that we are difficult to deal with. But "thinking systems" can open the doors of perception, allowing us to experience the world in a different way. This book offers both coaching ideas and stories from leaders as to strategies to break out from social control by de-triangling, using paradoxes, reversals and other types of interruptions of highly linked emotional processes. Time is needed to think clearly about the automatic nature of the two against one triangle. Time and experience is required as we learn strategies to put two people together and get self outside the control of the system. In addition, it takes time to clarify and define one's principles, to know what "I" will or will not do and to be able to take a stand with others with whom we are very involved. The good news is that systems' thinking is possible for anyone. It is always possible for an individual to understand feelings and to integrate them with their more rational brains. In so doing, an individual increases his or her ability to communicate despite misunderstandings or even rejection from important others. The effort involved in creating your Mindful Compass enables us to perceive the relationship system without experiencing it's threats. The four points on the Mindful Compass are: 1) Action for Self, 2) Resistance to Forward Progress, 3) Knowledge of Social Systems and the 4) The Ability to Stand Alone. Each gives us a view of the process one enters when making an effort to define a self and build an emotional backbone. It is not easy to find our way through the social jungle. The ability to know emotional systems well enough to take a position for self and to become more differentiated is part of the natural way humans cope with pressure. Now people can use available knowledge to build an emotional backbone, by thoughtfully altering their part in the relationship system. No one knows how far one can go by making an effort to be more of a self-defined individual in relationships to others. Through increasing emotional maturity, we can find greater individual freedom at the same time that we increase our ability to cooperate and to be close to others.

Download or read book Military Strategy and Tactics written by Reiner Huber and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 350 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume brings forth a set of selected papers from the Conference on Modeling Land Sattle Systems for Military Planning. Sponsored by the Special Programme Panel on Systems Science of the NATO Science Committee, the conference took place in Ottobrunn, Germany, at the War Gaming Centre of Industrieanlagen-Betriebsgesellschaft. The idea to organize a conference on land battle systemmodelswas first suggested to me in 1g72 by Andreas Mortensen, then a member of the Norwegian Defence Research Establishment and presently at the SHAPE Technical Centre, when we discussed the apparent inconsistencies of various evaluations of force capability within NATO. Frequently, decision makers are confronted by contradictory results of different studies addressing essentially the same problern leaving them with the impression that the tools of systems analysis and operations research may not be very objective guides. However, experienced systems researchers know that a detailed comparison of models, their assumptions and inputs, would generally show that results are not really contradictory. But not only seem the decision processes in large national and international organizations tobe suchthat a comparison can hardly ever be accomplished, also the docu mentation available is rarely sufficient to really camprehend the differences in results. For these reasons, we felt that an effort to review the state of the art of model ing in support of force capabil ity assessments was overdue.
Download or read book The Shapes of Knowledge from the Renaissance to the Enlightenment written by D.R. Kelley and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 254 pages. Available in PDF, EPUB and Kindle. Book excerpt: The original idea for a conference on the "shapes of knowledge" dates back over ten years to conversations with the late Charles Schmitt of the Warburg Institute. What happened to the classifications of the sciences between the time of the medieval Studium and that of the French Encyclopedie is a complex and highly abstract question; but posing it is an effective way of mapping and evaluating long term intellectual changes, especially those arising from the impact of humanist scholarship, the new science of the seventeenth century, and attempts to evaluate, to apply, to reconcile, and to institutionalize these rival and interacting traditions. Yet such patterns and transformations cannot be well understood from the heights of the general history of ideas. Within the ~eneral framework of the organization of knowledge the map must be filled in by particular explorations and soundings, and our project called for a conference that would combine some encyclopedic (as well as interdisciplinary and inter national) breadth with scholarly and technical depth.

Download or read book Adhesion Between Polymers and Concrete Adh sion Entre Polym res Et B ton written by H. R. Sasse and published by Springer. This book was released on 1986 with total page 792 pages. Available in PDF, EPUB and Kindle. Book excerpt: Preface Adhesion is a phenomenon architects and civil engineers are not very familiar with. In other disciplines knowledge about surface properties and the background of bonding energies is also far from satisfactory; nevertheless there are many important· applications in concrete engineering, where adhesion is necessary for success and durability. These include: - coating and painting - repair of concrete surfaces - bonding of fresh to old concrete - crack injection - glueing of precast elements - glueing of steel to concrete, etc. In 1981 RILEM established the technical committee 52-RAC 'Resin Adherence to Concrete'. The main aims of the committee's work were - to collect research results and practical experiences - to initiate and coordinate research programs - to develop, on a scientific base, test methods for field and for laboratory purposes. One of the results of the committee's work is a state-of-the-art report, which will be presented orally as a General Report at the International Symposium ISAP '86, and will be printed either in the RILEM journal Materials and Structures or separately. Several test recommendations have been elaborated and will be prepared as drafts for the participants ofISAP '86. These are: - direct tensile test - pull-off test - direct shear test - slant shear test - four-point bending test - dynamic loading test - thermal compatibility test (two versions) - injectibility test.
