Recently personal data storage and management have become one of the most important issues in the field of information technologies. 2018 was the year when well-known GDPR was issued which stated general personal data protection regulations. It’s very important to study methods and tools which can enhance the security of information systems processing personal data. Distributed data storages are widely used for fault tolerance as well as cryptography is used for access control.

The nonlinear mathematical model of contaminant distribution in unsaturated catalytic porous media to the filter-trap in isothermal conditions is presented. The mathematical model takes into account the micro and the meso/macro scale factors of the heat and mass transfer processes. The numerical solution of the respective boundary value problem was obtained by the method of finite differences. The analytical solution for mass transfer in nanoparticles was presented as well.

The paper suggests an approach to modelling the electrocoagulation process taking into account the ratio between the values of the parameters which characterize the domination of convective and mass-exchange components of the process over diffusion. Computer simulation of the distribution of iron concentration inside the electrocoagulator that allows predicting various hydrodynamic phenomena such as internal recirculation that affects the formation of a coagulant was conducted

The article presents some definitions of derivatives for set-valued mappings and their properties. A linear set-valued differential equation is considered and conditions for the existence of basic solutions are given. Subsequently, one optimal control problem is considered, when the system behavior is described by linear set-valued differential equations.
