La résolution du problème d'allocation de charge représente un enjeu important dans l'exploitation des machines parallèles. Nous faisons d'abord une étude bibliographique de ce problème dans le cadre des architectures à mémoire distribuée en mettant l'accent sur l'allocation dynamique, plus précisément sur l'équilibrage et la régulation de charges régulières. Une stratégie originale de régulation basée sur un calcul de préfixe généralisé est proposée. Elle s'avère à la fois correcte, exacte et indépendante du réseau d'interconnexion de processeurs. Un noyau de régulation de charge basé sur cette stratégie est développé. Nous poursuivons ensuite avec une analyse de son temps total d'exécution. Nous trouvons qu'une loi de probabilité de Gumbel modélise le temps maximal d'exécution. A partir de ce résultat nous inférons des politiques d'initiation et de décision pour la mise en oeuvre de là stratégie proposée. L'algorithme de régulation ainsi obtenu est donc efficace. Une application de simulation des phénomènes mécaniques, déformation-recristallisation à chaud des agrégats polycristallins, est développée. Pour cette application dynamique nous utilisons le noyau de régulation de charge avec les politiques d'initiation et décision proposés. L'algorithme complet s'avère en pratique correct, stable et efficace.

This comprehensive monograph celebrates the visual art of renowned musician Brian Eno. Spanning more than 40 years, Brian Eno: Visual Music weaves a dialogue between Eno's museum and gallery installations and his musical endeavors—all illustrated with never-before-published archival materials such as sketchbook pages, installation views, screenshots, and more. Steve Dietz, Brian Dillon, Roy Ascott, and William R. Wright contextualize Eno's contribution to new media art, while Eno himself shares insights into his process. Also included is a download code for a previously unreleased piece of music created by Eno, making this ebook a requisite for fans and collectors.

The UNESCO Convention on the Protection and Promotion of the Diversity of Cultural Expressions (CDCE) was adopted in 2005 and designed to allow States to protect and promote cultural policies. This book examines the effectiveness of the CDCE and offers ways by which its implementation may be improved to better attain its objectives. The book provides insight in how the normative character of the CDCE may be strengthened through implementation and increasingly recurrent practice based on its provisions. Hailing from various fields of international law, political and social sciences, the book’s contributors work to promote discussions on the practical and legal influence of the CDCE, and to identify opportunities and recommendations for a more effective application. Part One of the book assesses the effectiveness of the CDCE in influencing other areas of international law and the work conducted by other intergovernmental organizations through the recognition of the double nature (cultural and economic) of cultural goods and services. Part Two focuses on the practice of the CDCE beyond the recognition of the specificity of cultural goods and services in international law by addressing the CDCE’s call for greater international cooperation and stronger integration of cultural concerns in development strategies at the national and regional levels. The book will be of great use and interest to academics and practitioners in law, social and political sciences, agents of governmental and international organizations, and cultural sector stakeholders.
Nonsmooth Optimization contains the proceedings of a workshop on non-smooth optimization (NSO) held from March 28 to April 8,1977 in Austria under the auspices of the International Institute for Applied Systems Analysis. The papers explore the techniques and theory of NSO and cover topics ranging from systems of inequalities to smooth approximation of non-smooth functions, as well as quadratic programming and line searches. Comprised of nine chapters, this volume begins with a survey of Soviet research on subgradient optimization carried out since 1962, followed by a discussion on rates of convergence in subgradient optimization. The reader is then introduced to the method of subgradient optimization in an abstract setting and the minimal hypotheses required to ensure convergence; NSO and nonlinear programming; and bundle methods in NSO. A feasible descent algorithm for linearly constrained least squares problems is described. The book also considers sufficient minimization of piecewise-linear univariate functions before concluding with a description of the method of parametric decomposition in mathematical programming. This monograph will be of interest to mathematicians and mathematics students.

The concept of emergence has seen a significant resurgence in philosophy and the sciences, yet debates regarding emergentist and reductionist visions of the natural world continue to be hampered by imprecision or ambiguity. Emergent phenomena are said to arise out of and be sustained by more basic phenomena, while at the same time exerting a "top-down" control upon those very sustaining processes. To some critics, this has the air of magic, as it seems to suggest a kind of circular causality. Other critics deem the concept of emergence to be objectionably anti-naturalistic. Objections such as these have led many thinkers to construe emergent phenomena instead as coarse-grained patterns in the world that, while calling for distinctive concepts, do not "disrupt" the ordinary dynamics of the finer-grained (more fundamental) levels. Yet, reconciling emergence with a (presumed) pervasive causal continuity at the fundamental level can seem to deflate emergence of its initially profound significance. This basic problematic is mirrored by similar controversy over how best to characterize the opposite systematizing impulse, most commonly given an equally evocative but vague term, "reductionism." The original essays in this volume help to clarify the alternatives: inadequacies in some older formulations and arguments are exposed and new lines of argument on behalf the two visions are advanced.
