With the expansion of computer networks, activities involving computer communication are becoming more and more distributed. Such distribution can include processing, control, data, network management, and security. Although distribution can improve the reliability of a system by replicating components, sometimes an increase in distribution can introduce some undesirable faults. To reduce the risks of introducing, and to improve the chances of removing and tolerating faults when distributing applications, it is important that distributed systems are implemented in an organized way.

Interference and coherence effects are also studied in relation to the radiation fields generated by atoms through the process of spontaneous emission.

Abstract:
In large-scale distributed systems, each application is realised through interactions among distributed components. To guarantee safe communication (no deadlocks and communication mismatches) we need programming languages and tools that structure, manage, and policy-check these interactions. Multiparty session types (MPST), a typing discipline for structured interactions between communicating processes, offers a promising approach. To date, however, session types applications have been limited to static verification, which is not always feasible and is often restrictive in terms of programming

Abstract:
Les applications en temps réel, telles que les systèmes de conférence multi-utilisateurs, ont des exigences de qualité de service élevées pour garantir une qualité d'expérience décente. De nos jours, la plupart de ces conférences sont effectuées sur des appareils sans fil. Ainsi, les appareils mobiles hétérogènes et la dynamique du réseau doivent être correctement gérés pour fournir une bonne qualité d’expérience. Dans cette thèse, nous proposons deux algorithmes pour construire et gérer des sessions de conférence basées sur un réseau défini par logiciel qui utilise à la fois la distribution m

Abstract:
Text communication is often perceived as lacking some components of communication that are essential in sustaining interaction or conversation. This interaction incoherency tends to make text communication plastic. It is traditionally devoid of intonation, pitch, gesture, facial expression and visual or auditory cues. Nevertheless, Instant Messaging (IM), a form of text communication is on the upward uptake both on PCs and on mobile handhelds. There is a need to rubberise this plastic text messaging to improve co-presence for text communications thereby improving synchronous textual discussion

Ce mémoire est consacré à l'étude de réseaux de communication sans fils haut débit fonctionnant dans la bande de fréquence 40 Ghz. Nous nous intéressons principalement aux réseaux de type LMDS (Local Multipoint Distribution System) puisque ce rapport s'inscrit dans le cadre d'un projet RNRT (Réseau national de recherche en télécommunications) appelé ERASME. Ce projet vise à étudier les performances d'un système LMDS basé sur la norme DVB (Digital Video Broadcasting). La couche MAC (Medium Access Control) utilisée dans la plateforme ERASME est étudiée dans le détail à l'aide d'un logiciel spéci

Abstract:
The size and conformational complexity of proteins and other large systems represent major challenges for today's methods of quantum chemistry.This thesis is centered around the development of new computational tools to gain molecular-level insight into electronic transitions in such systems. To meet this challenge, we focus on the polarizable embedding (PE) model, which takes advantage of the fact that many electronic transitions are localized to a smaller part of the entire system.This motivates a partitioning of the large system into two regions that are treated at different levels of theor

Abstract:
Two computationally fast fluid mechanical models for vertical axis turbines are the streamtube and the vortex model. The streamtube model is the fastest, allowing three-dimensional modeling of the turbine, but lacks a proper time-dependent description of the flow through the turbine. The vortex model used is two-dimensional, but gives a more complete time-dependent description of the flow. Effects of a velocity profile and the inclusion of struts have been investigated with the streamtube model. Simulations with an inhomogeneous velocity profile predict that the power coefficient of a vertical

Abstract:
Dissertação de Mestrado em Ciência Política.<br>Esta dissertação aborda o funcionamento do presidencialismo de coalizão brasileiro à luz da doutrina clássica da separação dos poderes. Destaca-se o quanto o Poder Executivo foi fortalecido pela Constituição de 1988, permitindo caracterizar o sistema de governo brasileiro como ultrapresidencialismo, enquanto, ao mesmo tempo, ressalta-se que o multipartidarismo vigente no país relativiza a concentração de poderes no Executivo, o que cria a necessidade de formação de governos de coalizão. Por fim, aborda-se a tendência de parlamentariz

L'interférence entre stations de base est considérée comme le principal facteur limitant les performances des réseaux cellulaires. Nous nous intéressons aux différents schémas de coordination multi-point (CoMP) proposés dans la norme LTE-A pour y faire face, en tenant compte de l'aspect dynamique du trafic et de la mobilité des utilisateurs. Les résultats sont obtenus par l'analyse mathématique de modèles markoviens et par des simulations du système. Nous montrons l'importance de l'algorithme d'ordonnancement sur les performances en présence d'utilisateurs mobiles, pour des services de télécha
