The paper deals with the results of experimentally determined influence of the chemical composition change of pure Ge-Se-Te glasses systems with the rare earths elements additions (Pr, Er and Ho in oxide or pure metal form) on electrical and dielectric properties of the glasses. We used...

Monte Carlo simulation of temperature dependence of electric conductivity of a model mixture system, which involves reaction with first order kinetics, was carried out on the basis of chemical kinetics laws. The temperature dependence of the conductivity of rubber compounds during the process of...

The application of advanced methods of process management is essential, especially in those fields in which activity durations can be determined only vaguely, while at the same time a highly competitive market enforces strict completion schedules through the implementation of penalties. The...
