    The objective of this thesis concerns principally two major subjects. The main contributions of the first subject of this work are: 1. The problem of generalized synchronization between two chaotic fractional non-commensurate ...
  • Boudjedour, Allaoua; Dalah, Mohamed (Université Frères Mentouri - Constantine 1, 2020-02-20)
    This thesis proposes to study the convergence of the regularized solution denoted (uρ, ϕρ) to the solution (u, ϕ) when the parameter ρ tends to 0. At the beginning of this work, we set the physical framework and the ...
  • Benhadri, Mimia; Zeghdoudi, Halim (Université Frères Mentouri - Constantine 1, 2020-01-16)
    Fixed point theory has a long history of being used in nonlinear di§erential equations, in order to prove existence, uniqueness, or other qualitative properties of solutions. However, using the contraction mapping principle ...
  • Megraoui, Fatima Zohra; Balaloui, Soheir (Université Frères Mentouri - Constantine 1, 2019-07-22)
    Most of the research on reliability theory has focused on the study of independence between the components of a system. However, in many real systems, dependence between components is one of the realistic and intractable ...
  • Djeridi, Zohra; Merabet, Abderrezak (Université Frères Mentouri - Constantine 1, 2019-07-07)
    The aim of this thesis, which was motivated by methodological problems that arise in the context of experimental trials, is to propose a hybrid Bayesian-frequentist approach using sequential Bayesian prediction of the index ...
  • Beghriche, Abdelefateh; Zeghdoudi, Halim (Université Frères Mentouri - Constantine 1, 2019-07-25)
    This thesis proposes a new distribution, called as A Size Baised Gamma Lindley distribution (SBGaL). Various statistical properties like stochastic ordering, moment method, maximum likelihood estimation, mean deviations ...
  • Bouhali, Keltoum; El Lagoune, Fateh (Université Frères Mentouri - Constantine 1, 2019-07-04)
    In this thesis, we study the existence/nonexistence in time as well as the asymptotic behavior of some viscoelastic problems in the presence of different damping and different nonlinearities in the sources. In this regard, ...
  • Bahi, Oussama; Dakhmouche, Maghlaoui (Université Frères Mentouri - Constantine 1, 2019-07-08)
    This work is intended as a contribution to the univariate statistics of extreme values and its applications to the calculation of risk. The purpose of this dissertation is to take a deep look at the statistical techniques ...
  • Aouicha, Lamia; Messaci, Fatiha (Université Frères Mentouri - Constantine 1, 2019-06-13)
    In this thesis, we are interested in the nonparametric estimation of the conditional density and the conditional mode, in a twice censorship model. This means that the response variable Y is right censored by a variable R ...
  • Hacene-Chaouche, Soumeya; Dalah, Mohamed (Université Frères Mentouri - Constantine 1, 2019-05-05)
    In second is electro-viscoelastic problem which modeling the antiplane shear deformation of a cylinder in frictional contact with a foundation. The process this thesis, we study two problems, the first is electro-elastic ...
  • Bououden, Rabah; Abdelouahab, Mohammed-Salah (Université Frères Mentouri - Constantine 1, 2019-05-02)
    This thesis focuses on chaotic discrete dynamical systems. A detailed study on the notions of discrete dynamical systems such as the notion of stability, bifurcations and chaos are available in this thesis. In this thesis ...
  • Kaarer, Ines; Ayadi, Abdelhamid (Université Frères Mentouri - Constantine 1, 2018-12-10)
    This work is devoted to find, among all the bounded operators B, the one which gives a maximal controllability, in the sense that the operator image Hu=∫S(T-s)Bu(s)ds is maximal in the state space, following the inclusion ...
  • Rouabah, Nour El Houda; Nemouchi, Nahima (Université Frères Mentouri - Constantine 1, 2019-05-19)
    The study of existing work shows that many of the asymptotic results obtained in the context of nonparametric statistics for right censored observations are based on the properties of the Kaplan Meier estimator of the ...
  • Kesmia, Mounira; Boughaba, Soraya (Université Frères Mentouri - Constantine 1, 2018-12-13)
    This thesis is based on the rigorous application of the theory of nonlinear dynamics and chaos to cardiac electrophysiology and more precisely to the control of cardiac alternans with a control signal constructed from ...
  • Laouira, Widad; Hamri, Nasr-Eddine (Université Frères Mentouri - Constantine 1, 2018-11-29)
    The mathematical theory of control has undergone a very important development and its scope currently covers many fields, including industry, economics and biology. . . This thesis deals with the study of the control ...
