Our aim is to present a numerical method for solving elliptical problems by theoretical discretization. In order to do it, a complete system of eigenfunctions of the Laplacean and the compactâ€¦ (More)

In some of his scientific papers and university courses, professor Silviu Sburlan has studied integral equations (see the list of references). Beside the theoretical qualitative analysis concerningâ€¦ (More)

The paper presents a metamodel for open distributed collaborative systems. Based on this metamodel there are also presented the specifications of a framework for collaborative applications dynamicâ€¦ (More)

The present paper describes a thermal shock problem on a semispace within the frame of linear thermoelasticity. The analytical solution is obtained and two type of a finite difference numericalâ€¦ (More)

In this paper we present same properties of Lie algebra sl(2), then we prove some relations in U = U(sl(2)) the enveloping algebra of sl(2) and determine all finite-dimensional U -modules. 1. The Lieâ€¦ (More)

This paper considers the problem of estimating the mixture parameter Î¸, the scale parameters Î»1, Î»2, the location parameters u, Î½ and the probability R = Pr (Y < X) when X and Y are independent,â€¦ (More)

We propose an integer sorting algorithm using P systems with mobile catalysts. The paper considers the case when the number of components of the vector to be sorted is a fixed number k. Theâ€¦ (More)

The method used to obtain the minimum-norm solution of a largescale system of linear inequalities proceeds by solving a finite number of smaller unconstrained subproblems. Such a subproblem has theâ€¦ (More)
