«The role of information technology in the control of complex system»

Download an article

Information technology in modern world play a considerable and maybe a major role in the control of complex systems. Information technology provide the possibility of active human participation in the development of important physical processes, phenomenon, events, which allow to use them in control theory of complex systems.

«Interconnection between melting, boiling and critical points»

Download an article

We received theoretical formulas of the interconnection between melting, boiling and critical temperatures. Uniform physical representation of melting, boiling and evaporation processes was the basis for deriving the formula of interconnection between them. We use the concept of the material substance internal energy in terms of the molecules “unpacking” idea. The reference manual data on 85 substances from 13 to 855 degrees Kelvin confirms the theoretically derived formulas. We carried out the comparison of theoretical formulas and experimental data by their mean values. A simple ideal substance model with spherical molecules was considered as a model of substance molecule. The melting point is 1/3, and the boiling point ranges from 1/2 to 2/3 of the critical point for this model.
