In this article, we compare the support for SIMD instructions for Julia and Fortran. The comparison is carried out according to the …

In certain scientific domains, there is a need for tensor operations. To facilitate tensor computations, computer algebra systems are …

The retrial queuing system with general renovation is under investigation. The mechanism of general renovation with retrials means that …

When modeling such phenomena as population dynamics, controllable flows, etc., a problem arises of adapting the existing models to a …

This paper discusses the application of stochastic Runge-Kutta-like numerical methods with weak and strong convergences for systems of …

To construct realistic mathematical models from the first principles, the authors suggest using the stochastization method. In a number …

Self-oscillating modes in control systems of computer networks quite negatively affect the characteristics of these networks. The …

Representing a probability density function (PDF) and other quantities describing a solution of stochastic differential equations by a …

For the study and verification of our mathematical model of telecommunication systems a discrete simulation model and a continuous …

Spinors are more special objects than tensor. Therefore possess more properties than the more generic objects such as tensors. Thus, …

The article is devoted to the application of Markov modu- lated arrival processes (Markov modulated Poisson process — MMPP, Markov …

Background. By the means of the method of stochastization of one-step processes we get the simplified mathematical model of the …

The mathematical model of light propagation in a planar gradient optical waveguide consists of the Maxwell’s equations …

This paper studies program implementation problem of pseudo-random number generators in OpenModelica. We give an overview of generators …

To synthesize Maxwell optics systems, the mathematical apparatus of tensor and vector analysis is generally employed. This mathematical …

This paper considers three types of tensor computations. On their basis, we attempt to formulate criteria that must be satisfied by a …

In this article we present two examples solved in a new problem-oriented computer algebra system Cadabra. Solution of the same examples …

This paper describes Lorentz two-spinors and proposes using them in calculations with Dirac four-spinors and quaternions.
