Nonlinear control Recently nonlinear control techniques such as sliding mode control, backstepping and inputoutput feedback linearization have drawn interest in power electronics applications since they offer systematic, powerful and easy-to-implement methods (Marino and Tomei 1996). A nonlinear frequency and voltage...
MESURE DIRECTE DU CHANGEMENT DE L’INDICE DE RÉFRACTION DES GUIDES D’ONDES CAF2 À DOUBLE PISTE Dans le prolongement de la caractérisation des propriétés des guides d’ondes, le chapitre 6 présente les mesures directes de l’indice de réfraction des guides d’ondes...
Manufacturing rotorblades LITERATURE REVIEW: In this chapter a review of the relevant literature is presented, in order to better understand the principles of the project and explain the basic concepts pertinent to the work. First, wood-plastic composites are introduced and...
Dans cette thèse, notre but est d’étudier des équations aux dérivées partielles (EDP) auxquelles nous introduisons l’aléatoire via une différentielle stochastique de type bruit blanc gaussien. En d’autres termes, l’aléatoire s’immisce dans l’EDP par le biais d’une intégrale stochastique, et...
Linear Quadratic Regulation (LQR) The advantage of the Linear Quadratic Regulation (LQR) method is that it provides the smallest possible error to both inputs and outputs while minimizing the control effort; the error corresponds to the difference between the desired...
The Genetic Algorithm The Genetic Algorithm (GA) was invented by Holland (1975), and was based on Darwin's theory of evolution. Researchers have worked intensively on hybrid GA and NN combinations since the late 1980s, utilizing the GA’s attributes to improve...
Finite element modeling of CFRP machining Recently, many researchers have focused on investigation of CFRP machining using modeling to decrease the experiments, which are time consuming and expensive. But in the literature, very few works attempt to model the cutting...
LENGTHENING OF THE DURATION OF XYLOGENESIS ENGENDERS DISPROPORTIONATE INCREASES IN XYLEM PRODUCTION In the past, the Earth has experienced a number of climate fluctuations. Glaciations and warmings succeeded one another and shaped the world as we know it today (IPCC,...
