New collocation path-following approach for the optimal shape parameter using Kernel method

Autor: Zouhair Saffah, Hassane Lahmam, Abdelaziz Timesli, Mohamed Amdi, Abderrahim Azouani

The goal of this work is to develop a numerical method combining Radial Basic Functions (RBF) kernel and a high order algorithm based on Taylor series and homotopy continuation method. The local RBF approximation applied in strong form allows us to o

Evolution Equations and Control Theory, vol 3, iss 4

We introduce here a simple finite-dimensional feedback control scheme for stabilizing solutions of infinite-dimensional dissipative evolution equations, such as reaction-diffusion systems, the Navier-Stokes equations and the Kuramoto-Sivashinsky equa

Effect of quasi-periodic gravitational modulation on the convective instability in Hele-Shaw cell

Autor: T. Boulal, Saïd Aniss, Mohamed Belhaq, Abderrahim Azouani

Publikováno v: International Journal of Non-Linear Mechanics. 43:852-857

The aim of the present paper is to examine the effect of a quasi-periodic gravitational modulation on the onset of convective instability in Hele-Shaw cell. The quasi-periodic modulation considered here consists in a modulation having two incommensur

Bursters and quasi-periodic solutions of a self-excited quasi-periodic Mathieu oscillator

Autor: Faouzi Lakrad, Abderrahim Azouani, Mohamed Belhaq, Nazha Abouhazim

Publikováno v: Chaos, Solitons & Fractals. 24:813-824

In this paper the conditions of occurrence of quasi-periodic (QP) solutions and bursting dynamics in a self-excited quasi-periodic Mathieu Oscillator are discussed. The quasi-periodic excitation consists of two periodic excitations; one with a very s

We present a new continuous data assimilation algorithm based on ideas that have been developed for designing finite-dimensional feedback controls for dissipative dynamical systems, in particular, in the context of the incompressible two-dimensional

We consider convex symmetric lens-shaped networks in R 2 \mathbb {R}^2 that evolve under the curve shortening flow. We show that the enclosed convex domain shrinks to a point in finite time. Furthermore, after appropriate rescaling the evolving netwo
