Abstract:

In this thesis, a new transport protocol, the Concurrent Multi-Path Real-time Transmission Control Protocol (cmpRTCP) is proposed. The proposed protocol has been designed to handle real-time streams (video and audio) over IP-networks. One of the key strengths of this protocol lies in its ability to intelligently exploit the availability of multiple paths between multi-homed hosts for concurrent transmission of unicast real-time streams. This work describes the architecture and operation of cmpRTCP in detail. In addition, the limitations of currently used transport protocols in handling real-ti

Abstract:

Un aspecte fonamental quan cal resoldre un problema vibroacústic en un sistema mecànic és el de determinar com flueix l’energia des d’una font donada, cap a qualsevol part del sistema. Això permet decidir quines són les accions a prendre per disminuir, per exemple, els nivells de soroll i vibracions en una determinada àrea del sistema. El comportament dinàmic d’un sistema mecànic es pot estimar utilitzant diversos mètodes numèrics, cadascun dels quals enfocat a un marge de freqüència determinat. Mentre a baixes freqüències es poden aplicar mètodes deterministes com el Mètode d’Elements Finits

Abstract:

This paper analyses the process of wealth accumulation with regard to the path dependence theory. Based on the theoretical foundations of Robert King Merton, Vilfredo Pareto and Pierre Bourdieu, mechanisms of wealth accumulation are analyzed. These mechanisms, which are understood as direct and indirect network effects, are formalized using the statistical computing software R. A base model without any mechanisms of wealth accumulation is developed, which makes it possible to include the analyzed mechanisms step by step and observe their effects on the process of wealth accumulation and social

Abstract:

<p>Large scale path loss modeling plays a fundamental role in designing both fixed and mobile radio systems. Predicting the radio coverage area of a system is not done in a standard manner. Wireless systems are expensive systems. Therefore, before setting up a system one has to choose a proper method depending on the channel environment, frequency band and the desired radio coverage range. Path loss prediction plays a crucial role in link budget analysis and in the cell coverage prediction of mobile radio systems. Especially in urban areas, increasing numbers of subscribers brings forth the ne

Le rendement d’un hélicoptère est étroitement lié à son poids. L’allègement des composants profite à la charge utile transportable.

Elles doivent assurer la transmission de puissances importantes à masse minimale. Les axes des roues dentées se désalignent alors progressivement au fur et à mesure de l’application du chargement.

The continuous growth of traffic demand driven by the brisk increase in number of Internet users and emerging online services creates new challenges for communication networks. The latest advances in Wavelength Division Multiplexing (WDM) technology make it possible to build Transparent Optical Networks (TONs) which are expected to be able to satisfy this rapidly growing capacity demand. Moreover, with the ability of TONs to transparently carry the optical signal from source to destination, electronic processing of the tremendous amount of data can be avoided and optical-to-electrical-to-optic

The fourth refers to the synthesis of subsystems and more specifically to two subsystems linked by any number of elastic elements. In the first topic it is proved that the solution of any linear mechanical system can be expressed as a linear combination of signal transmission paths. This is done in the framework of the Global Transfer Direct Transfer (GTDT) formulation for vibroacoustic problems. Transmission paths are expressed as powers of the transfer matrix.

But, do Drosophila astrocytes have parallel roles in the regulation of synaptic signaling?

Abstract:

Les terminaux de communications sans fil évoluent en des terminaux supportant plusieurs standards. L'un des challenges est d'utiliser le meilleur standard au bon moment. L'émetteur d'une radio cognitive agile en fréquence se doit d'être reconfigurable afin de transmettre l'information dans des bandes fréquentielles sous utilisées et d'avoir recours au standard offrant la meilleure qualité de communication. L'élément le plus critique dans un émetteur est l'étage de puissance et sa connexion avec l'antenne. Les principaux problèmes devant être pris en compte par l'amplificateur de puissance (PA)

Abstract:

La substance noire réticulée (SNr) est la principale structure de sortie des ganglions de la base (BG), un réseau sous-cortical contrôlant l'élaboration des programmes moteurs ainsi que des fonctions d'apprentissage cognitives et associatives. L'identification de types de cellules distincts dans le BG a joué un rôle clé pour comprendre les propriétés et les fonctions de ce circuit. Des études récentes suggèrent que la SNr est composé de plusieurs types de cellules mais jusqu'à présent cette diversité neuronale n'a jamais été prise en compte concernant le fonctionnement normal et pathologique d

Abstract:

Le neurone est une cellule polarisée qui se divise en deux compartiments spécialisés : le compartiment somato-dendritique et le compartiment axonal. Généralement, le premier reçoit l'information en provenance d'autres neurones et le second génère un message en sortie lorsque la somme des entrées dépasse une valeur seuil au segment initial de l'axone. Ce signal de nature discrète appelé potentiel d'action (PA) est propagé activement jusqu'à la terminaison synaptique où il déclenche la transmission chimique de l'information. Cependant, la fonction axonale ne se résume pas à la simple transmissio

Abstract:

La sclérose latérale amyotrophique (SLA) est une maladie neurodégénérative fatale de l’adulte caractérisée par la dégénérescence des motoneurones (MNs) et ayant une étiologie multifactorielle. La plupart des études sur la SLA se sont focalisées aux stades symptomatiques selon l’hypothèse que la pathogénicité apparaît lorsque la maladie devient symptomatique. Cependant, un nombre grandissant d’évidences indique que la pathogénicité se développerait bien avant les symptômes. Mon travail de thèse de Doctorat a été basé sur l’hypothèse selon laquelle la SLA – familiale et sporadique – découlerait
