Modèles probabilistes et statistiques pour la conception et l’analyse des systèmes de communications
Internet is the first real multi-service network; voice, video and data services are all offered on the same network. Among the many consequences that this convergence brought with it, the change on the traffic structure is probably between the most...
La théorie des matrices aléatoires présente un ensemble d’outils mathématiques efficaces pour l’étude de performances des systèmes de communications numériques. L’objectif de cette thèse est de développer des résultats analytiques basés sur la théorie des matrices aléatoires pour étudier les...
The work presented in this PhD thesis has been produced thanks to the collaboration of the teams "Digital Communications" and "Optical Telecommunications" of the department "Communications and Electronics" (COMELEC) at Telecom ParisTech in the framework of a "Futur & Ruptures"...
Solution characterization for relaxed constraint satisfaction problems This chapter presents several methods to represent the solution of a relaxed constraint satisfaction problem or relaxed CSP (See de.nition 2.2). A relaxed CSP can usually be represented by a set of equations...
Reliability is of critical importance in various types of electrical and mechanical systems. A well-known and complex reliability optimization problem is the redundancy apportionment problem (RAP) for series-parallel systems which can be identified as the selection of the optimal combination...
Applications of computer to measure complex ecological properties and patterns - moving beyond single-feature metrics. In Chapter 3, l investigate and develop new automated tools for rapidly quantifying ecosystem features and visual patterns. The data derived from such metrics, or...
Aircraft Performance modeling The main goal of an aircraft performance model is to predict with a certain level of accuracy the actual aircraft and engine performance. The word “performance” in this context refers mainly to flight parameters describing the aircraft...
The study of the Vertical Take-Off and Landing (VTOL) Unmanned Aerial Vehicle (UAV) has been growing intensively by researchers in the recent decades. The UAVs have gradually been adopted by the public to be used in several areas. In fact,...
Hydroelectric power is currently the most common form of renewable energy and plays a very important role in global electric power generation. It accounts for approximately 17.5% of total electricity production, and almost 85% of electricity produced from renewable sources...
Massive MIMO and millimeter-wave Network densification and the use of extremely high frequencies (EHF), commonly known as millimeter-wave band, are the two most promising candidates for the future wireless access to fulfill the ever-increasing capacity demands. It is the small...
