The System offers transparent accounting of operations donors, charitable foundations and recipients based on blockchain technology, charitable platform should provide transparent donation route, enable public users and donors to track and monitor where, when and to whom went resources of charity funds.

The article is dedicated to implementation and evaluation of a model for simulation of emergency situations on main gas pipeline. Data produced by model was compared to data obtained from real emergency situations on main gas pipeline. Result of this work is the model built using MATLAB Simulink software that can be used for datasets generation, which are useful for artificial neural networks training.
