Définition 1.2. Un groupe (G,+) est dit abélien, si la loi + est commutative. Notation 1.1. Lorsque (G,+) est un groupe abélien, l’élément neutre est souvent noté 0G et l’inverse d’un élément x est noté −x. Exemple 1.1. Un ensemble à un élément, x, est un groupe abélien pour la loi + définie par x+ x ∆ = x. Preuve 1. + est associative. 2. + est commutative. 3. x est un élément neutre car pour t...

Based on the principles of system thought and related enterprise integration methodologies, a process oriented methodology and ICMMS (Intelligent Control-Maintenance-technical Management Systems) reference model for hydropower plants are proposed. Because the structures of the hydropower generating process are unchanging from the point of view of energy conversion, the methodology employs the p...

In this paper, we carry out a simulation of a Radio over Fiber (RoF) link with VPI Transmission Maker, and Rohde&Schwarz (R&S) equipments. The VPI simulations perform optical path degradations for multiple radio modulation formats without using any specific radio numerical tools, while a Generator and a Vector Analyser are used for radio generation and reception.

Since the beginnings of computer science, computers have been used fruitfully for the generation of new music. In the last decades, their utilization to create generative systems moved from the implementation of tools for composition towards the invention of reactive programs aimed at participating in the much more unpredictable and challenging situation of musical improvisation. The work prese...

This thesis proposes a mathematical framework for studying feedback effects and endogenous risk in financial markets. We propose a multi-period model of a financial market with multiple assets, which takes into account the price impact generated by large shifts in supply and demand from financial institutions. Chapter 1 reviews the existing empirical and theoretical literature on feedback effec...
