In this work, the method of Muskhelishvili’s complex potentials is used to solve the boundary value problem of elasticity theory for a domain in the form of a ring with piecewise constant boundary conditions on the contour. ...

The evolution equations modeling many process that appear in physique, ecologies, hydrogeology, finance etc. For example, the mathematical model of the problem to transport any substance in atmosphere, because of the ...

Soil erosion, by water agent, is understood as a moving process of a certain quantity of soil particles from a soil surface point to another point. The presence of the plants strongly affect the erosion process, the plant ...

Experimental research focused on 6 products (bioactive compounds extracts from forest fruits and agro-food industry waste) and a maximum of 9 experimental parameters determined. The purpose of applying the stochastic ...

The paper concerns with the error analysis of two time-stepping schemes used in the discretization of the phase-field transition system with a classical regular potential (Caginalp’s model) and Neumann boundary conditions. ...

Several new analytic methods are proposed here basing on the diagonalization procedure for arbitrary square system of PDEs (partial differential equations) with the piecewise constant coefficients. Engineering applications ...

Let’s consider L(u) = a(x, t)utt + b(x, t)utx + c(x, t)uxx + d(x, t)ut + h(x, t)ux, x ∈ R1. The second order quasilinear equations are studied in the following form: L(u) + r(u) a(x, t)u 2 t + b(x, t)utux + c(x, t)u 2 x + ...

Some of the central problems in computer science and, in particular, in programming are the correctness and the similarity problems, which contain: the question of whether a program computes a given function; the problem ...

Image interpolation, known also as inpainting or completion, represents the process of recovering the missing or highly deteriorated regions of the image, as plausibly as possible, by using the information achieved from ...

The paper presents the CAD (Autodesk Inventor) modelling and CAE simulation of precessional drives capable of high transmission ratio and torque for one stage compact construction. The simulations of the drives provide ...
