Forecasting concentration levels is important for planning atmospheric protection strategies. In this paper, we focus on the daily average surface ozone (O3) concentration with a short-time resolution (one day ahead) in the Grand Casablanca Region of

The main goal of this paper is to adapt a class of complexity reduction methods called aggregation of variables methods to the construction of reduced models of two-time reaction-diffusion-chemotaxis models of spatially structured populations and to

Optimization by Hybridization of a Genetic Algorithm with the PROMOTHEE Method: Management of Multicriteria Localization

Autor: Amal Bergam, Mostafa Bachran, Otman Abdoun, Myriem Alijo

The decision to locate an economic activity of one or several countries is made taking into account numerous parameters and criteria. Several studies have been carried out in this field, but they generally use information in a reduced context. The ma

Approximate solutions of a quadratic functional equation in 2-Banach spaces using fixed point theorem

Autor: Amal Bergam, Khaled Yahya Naif Sayar

Publikováno v: Journal of Fixed Point Theory and Applications. 22

In this paper, we investigate some stability and hyperstability results for the following quadratic functional equation: $$\begin{aligned} f(x+y)+f(x-y)=2f(x)+2f(y) \end{aligned}$$in 2-Banach spaces using Brzdȩk’s fixed point approach.

A posteriori error estimates for a finite volume scheme applied to a nonlinear reaction-diffusion equation in population dynamics

Autor: Hatim Tayeq, Amal Bergam, Anouar El Harrak

Publikováno v: Discrete & Continuous Dynamical Systems - S. 14:2183

This work gives a posteriori error estimates for a finite volume implicit scheme, applied to a two-time nonlinear reaction-diffusion problem in population dynamics, whose evolution processes occur at two different time scales, represented by a parame
