    Djamel Barkat; Ezzedine Srasra; Abdelkader Ouakouak; Noureddine Rouahna;
    doi: 10.1088/2053-1591/ab73fe
    Publisher: IOP Publishing

    This paper aims at studying the preparation of Zn-Al-LDH anionic clay and its adsorption proprieties in removing orthophosphate ions from aqueous medium. The LDH phase was synthesized by co-precipitation method and then calcined at 500 °C. Structural and textural proper...

    Coulomb potential in one dimension with minimal length: A path integral approach
    Open Access English
    Authors:
    Khireddine Nouicer;
    doi: 10.1063/1.2809267

    We solve the path integral in momentum space for a particle in the field of the Coulomb potential in one dimension in the framework of quantum mechanics with the minimal length given by $(\Delta X)_{0}=\hbar \sqrt{\beta}$, where $\beta$ is a small positive parameter. Fr...

    Graphical Stabilization Approach for Unstable First Order Linear Systems with Time Delay
    Open Access
    Authors:
    Daoud Berkani; A. Maddi; Abderrezak Guessoum;
    doi: 10.18100/ijamec.2017specialissue30464
    Publisher: International Journal of Applied Mathematics, Electronics and Computers

    In this paper, a graphical stabilization approach is proposed and analyzed for a class of unstable first order linear systems with time delay. We first show that the control designs based on time invariant models are unable to guarantee stability and asymptotic tracking...

    doi: 10.1007/978-90-481-2669-9_62

    Several disorders observed in an existing work on civil engineering may have their origin in local phenomena which reveal the weak points of this work. These critical zones are located, on the one hand in the links between materials or interfaces, on the other hand in s...

    Time behavior of a Gaussian wave packet accompanying the generalized coherent state for the inverted oscillator
    Open Access
    Authors:
    Jeong Ryeol Choi; Mustapha Maamache; Yacine Bouguerra;
    doi: 10.1093/ptep/ptw057
    Publisher: Oxford University Press (OUP)

    A Gaussian wave packet of the inverted oscillator is investigated using the invariant operator method together with the unitary transformation method. A simple wave packet directly derived from the eigenstates of the invariant operator of the system corresponds to a pla...
