This paper deals with the determination of an initial condition in the degenerate two-dimensional parabolic equation \[\partial_{t}u-\mathrm{div}\left(a(x,y)I_2\nabla u\right)=f,\quad (x,y)\in\Omega,\; t\in(0,T),\] where \(\Omega\) is an open, bounde

In this article we consider a mathematical model that describes the quasi-static process of contact between a thermo-electro-viscoelastic body and a conductive foundation. The constitutive law is assumed to be linear thermo-electro-elastic and the

We consider a fractional model describing phase transition in ferromagnetic materials. This model includes the three-dimensional evolution of both thermodynamic and electromagnetic properties of the ferromagnetic material. We first prove existence

In this article, we use the variational method in data assimilation to study numerically the null controllability of degenerate/singular parabolic problem $$\displaylines{ \partial _{t}\psi - \partial_{x}(x^\alpha\partial _{x}\psi(x)) -\frac{\la

The paper deals with global existence of weak solutions to a one-dimensional mathematical model describing magnetoelastic interactions. The model is described by a fractional Landau-Lifshitz-Gilbert equation for the magnetization field coupled to an

One of the pertinent concerns in traffic management is to optimize the waiting time at the traffic light junctions. We have has already developed an integrated nonlinear model which heavily relies on the genetic algorithm (GA). Indeed, GA proves effi

The aim of this paper is to study a Signorini?s problem with Coulomb?s friction between a thermo-electro-viscoelasticity body and an electrically and thermally conductive foundation. The materiel?s behavior is described by the linear thermo-electro-v

This paper presents the SIR space-time model, which is a coupled reaction-diffusion system with nonlinear Robin boundary conditions. These boundary conditions are supposed to lock the border (no outflow neither immigration nor migration) when the num
