Full textWe present in this thesis the study of two non-linear optical systems. The first problem that we analyze is the collective atomic recoil laser (CARL) in a vapor of two-level atoms. We emphasize the various irreversible processes, present in any experiment, that are likely to counteract the development of the instability. We point out the existence of two different types of phase transition and show that they are independent of the details of the thermalization processes. The study is both numerical and analytic. We specify the necessary conditions in order to observe the first kind of transition while we compare our results for the second instability with recent experimental results. The second problem concerns the dynamics of two lasers coupled via delayed injection. We show how this system, a priori simple, induces very rich dynamics when the delay term is included. We present a mechanism of bridge formation between periodic solutions with different symmetries via secondary bifurcation and asymmetric quasi-periodic solutions. This study is performed using analytical methods and a continuation based algorithm
In questa tesi, presentiamo lo studio di due sistemi ottici non lineari. Il primo problema analizzato 'e l'effetto laser ottenuto mediante rinculo atomico (CARL), in un vapore di atomi a due livelli. In questo studio, consideriamo in modo esplicito I diversi processi irreversibili, presenti negli esperimenti, che possono impedire la formazione delle instabilità. In questo sistema dinamico, mettiamo in evidenza l'esistenza di due tipi di transizione di fase e mostriamo che quest'ultime sono indipendenti dai dettagli del processo di termalizzazione. Questo studio e realizzato numericamente e analiticamente. Per la prima transizione, presentiamo le condizioni necessarie alla sua osservazione, mentre per la seconda transizione, confrontiamo i nostri risultati con delle recenti osservazioni sperimentali. Nella seconda parte di questa tesi, ci interessiamo alla dinamica di due laser accoppiati tramite un termine di ritardo. Mostreremo come un sistema, a priori semplice, composto da due laser, può avere una dinamica estremamente ricca grazie al termine di ritardo. Presentiamo un meccanismo di formazione di ponti di connessione tra le soluzioni periodiche con simmetrie diverse tramite delle biforcazioni secondarie e delle soluzioni quasi-periodiche asimmetriche. Questo studio e realizzato analiticamente e numericamente, grazie all'utilizzazione di algoritmi di continuazione

Full textThe works of this thesis concern the modeling and the numerical study of thesystems of two coupled nonlinear Schrödinger equations. At first, we considered aparity-time-symmetric system of the two coupled nonlinear Schrödinger (NLS) equationsthat modeled phenomenons in birefringent nonlinear optical fiber. We studythe behavior of the solution in some spaces like the Sobolev space H1. And we studythe numerical aspect of the model which clearly shows the behavior of the solutionin the chosen space. For the same model in higher dimension, we establish sufficientconditions for the initial conditions to blow up in finite time for some nonlinearityand for others we do the numerical study of the model and we present some casesof blowing up of the solution in finite time and also of the solutions of the modelthat exist all the time. On the other hand, we address a new model of discrete nonlinearSchrödinger equations PT -symmetric. A such model describes dynamics inthe chain of weakly coupled pendula pairs near the resonance between the parametricallydriven force and the linear frequency of each pendulum. In order to studythe stability of the pendulums, we establish sufficient conditions on the parametersof the model so that the equilibrium solution is stable. Numerical experiments arepresented to validate the analytical results and to characterize the unstabilizationof the coupled pendulum chain in the region of instability

Full textThe main goal of this thesis is the study of the asymptotic behavior of global solutions to some nonlinear evolutions equations and coupled systems with different types of dissipation and boundary conditions. Under the assumption that the non-linear term is real analytic, we construct an appropriate Lyapunov energy and we use the Lojasiewicz-Simon inequality to show the convergence, and the convergence, and the convergence rate, of global weak solutions to single steady states. For all models studied in this thesis, we are in addition interested in the questions of the existence and uniqueness of global bounded solutions having relatively compact range in the natural energy space. This thesis consists of three main parts. In the first part, we present a unified approach to study the asymptotic behavior and the decay rate to a steady state of bounded weak solutions for an abstract non-autonomous nonlinear equation with linear dissipation. This result allows us to find and to generalize, in a natural way, known results but it applies to a quite general class of equations and coupled systems with different kinds of coupling and various boundary conditions. The second part is devoted to the study of a nonautonomous semilinear second order equation with nonlinear dissipation and a dynamical boundary condition. We prove the existence and uniqueness of global, bounded, weak solutions having relatively compact range in the natural energy space and we show that every weak solution converges to equilibrium. Finally, we consider a nonautonomous, semilinear, hyperbolic-parabolic equation subject to a dynamical boundary condition of memory type. We prove the existence and uniqueness of global bounded solutions having relatively compact range and we show the convergence of global weak solutions to single steady states. We prove also an estimate for the convergence rate. The first chapter of this thesis consist of a preliminary introduction developing not only the story of researches linked to our models and the results described in the literature, but presenting also our main results as well the ideas of their proofs. There we discuss the complexity of our problems and we present a justification for our studies

Full textIn this Thesis, the robust design with an uncertain model of a vibro-impact electromechanical system is done. The electromechanical system is composed of a cart, whose motion is excited by a DC motor (motor with continuous current), and an embarked hammer into this cart. The hammer is connected to the cart by a nonlinear spring component and by a linear damper, so that a relative motion exists between them. A linear flexible barrier, placed outside of the cart, constrains the hammer movements. Due to the relative movement between the hammer and the barrier, impacts can occur between these two elements. The developed model of the system takes into account the influence of the DC motor in the dynamic behavior of the system. Some system parameters are uncertain, such as the stiffness and the damping coefficients of the flexible barrier. The objective of the Thesis is to perform an optimization of this electromechanical system with respect to design parameters in order to maximize the impact power under the constraint that the electric power consumed by the DC motor is lower than a maximum value. To chose the design parameters in the optimization problem, an sensitivity analysis was performed in order to define the most sensitive system parameters. The optimization is formulated in the framework of robust design due to the presence of uncertainties in the model. The probability distributions of random variables are constructed using the Maximum Entropy Principle and statistics of the stochastic response of the system are computed using the Monte Carlo method. The set of nonlinear equations are presented, and an adapted time domain solver is developed. The stochastic nonlinear constrained design optimization problem is solved for different levels of uncertainties, and also for the deterministic case. The results are different and this show the importance of the stochastic modeling

Full textThis work is devoted to the study of some controllability problems concerning some models from fluid mechanics. First, in Chapter 2, we obtain the local null controllability of the Navier-Stokes system with distributed controls having one vanishing component. The main novelty is that no geometric condition is imposed on the control domain. In Chapter 3, we extend this result for the Boussinesq system, where the coupling with the temperature equation allows us to have up to two vanishing components in the control acting on the fluid equation. Chapter 4 deals with the existence of insensitizing controls for the Boussinesq system. In particular, we prove the null controllability of the cascade system arising from the reformulation of the insensitizing problem, where the control on the fluid equation has two vanishing components. For these problems, we follow a classical approach. We establish the null controllability of the linearized system around the origin by means of a suitable Carleman inequality for the adjoint system with source terms. Then, we obtain the result for the nonlinear system by a local inversion argument.In Chapter 5, we study some null controllability aspects of a linear KdV equation with Colin-Ghidaglia boundary conditions. First, we obtain an estimation of the cost of null controllability, which is optimal with respect to the dispersion coefficient. This improves previous results on this matter. Its proof relies on a Carleman estimate with an optimal behavior in time. Finally, we prove that the cost of null controllability blows up exponentially with respect to the dispersion coefficient provided that the final time is small enough
