Mathematical Simulation of Nanofiltration Process: State of Art Review

A review of publications devoted to the mathematical simulation of the nanofiltration process was carried out, the advantages, limitations, and areas of application of various modeling approaches were determined. It was found that the most effective approaches are based on the extended Nernst-Planck equation, Donnan equilibrium, as well as methods of computational fluid dynamics and molecular dynamics. The use of software for solving nanofiltration simulation problems was considered.

Role, Problems, and Methods of Software Security Testing Automation

In the modern world, where information security becomes a key element of any organization's operations, software security testing automation is more important than ever. The success of an application directly depends on its stability, reliability, and security, which makes the proper implementation of control mechanisms critical. The increase in cyber threats and the growing complexity of software systems make this topic even more relevant.

Improved Software System for Calculating the Reliability Indicators of Complex Technical Systems

The article analyses the literature sources, which investigate the existing methods and means of calculating reliability indicators of complex technical (in particular, software) systems. The reliability model of a modern complex technical system is often depicted in the form of a reliability block diagram (RBD), which may contain thousands of elements, each transitioning between different states (e.g., operational, failed, restored). This leads to a vast space of possible states in the corresponding Markov model.

Principles of Creating Multi-objective Quality Models for Software Systems

This article proposes an original approach at a mathematical level to the creation of multi- objective quality models for software systems. The research is based on the study and generalization of quality modeling trends of software systems and user needs in order to determine optimal principles for constructing such  models. The article provides mathematical explanations that play a key role in identifying and formalizing the principles of creating multi-objective quality models of software.

A decision support software system for cryptocurrency traders on the Trading View platform

The work carried out a comparative analysis of scientific publications regarding the possibility of predicting the direction of the cryptocurrency exchange rate using the data of open numerical indicators, based on the results of which it can be concluded that due to the volatility of the cryptocurrency market and the need for accurate forecasting, there is a need to create an aggregated indicator that will take into account the current price exchange rate asset, parameters of simple indicators, trading volume, etc.

A method of automating the process of calculating reliability indicators of software systems and their components

The existing means of calculating reliability indicators of software systems are analyzed. It has been established that to determine the reliability indicators of software systems, it is advisable to use the structural-logical analysis of reliability block diagrams, since it clearly and most adequately reflects the process of calculating the reliability indicators of the software system as a whole and its components in particular.

Mathematical modeling of impurity diffusion process under given statistics of a point mass sources system. I

The model of the impurity diffusion process in the layer where a system of random point mass sources acts, is proposed.  Mass sources of various power are uniformly distributed in a certain internal interval of the body.  Statistics of random sources are given.  The solution of the initial-boundary value problem is constructed as a sum of the homogeneous problem solution and the convolution of the Green's function and the system of the random point mass sources.  The solution is averaged over both certain internal subinterval and the entire body region.  Simulation unit
