The paper is devoted to the numerical solution of an elastoplastic constitutive initial value problem containing the Mohr-Coulomb yield criterion, a nonassociative plastic flow rule, and a nonlinear isotropic hardening. The constitutive problem is discretized by the implicit Euler method. Instead of the conventional Koiter formulations, we define the plastic flow rule using the subdifferential ...

In this paper, we present a localization system for the use of drone in remote laboratory. The objective is to allow inspect electronic instruments autonomously, as well return its base and land on platform recharge batteries. addition, should be able detect presence teacher laboratory center human face image order enable student–teacher communication. To achieve first objective, approach compo...

Planar microphone arrays are of common use in acoustic source identification methods, as well the planar calculation grids. Indeed, assumption is that grid contains all sources interest. However, this may not be true several applications and hence return misleading results. One tentative to overcome issue consider three-dimensional surface adhering on target. Unfortunately, also choice enough o...
