In the paper is given integral expression of energy of non-linear physical system. If to take as argument the generalized coordinate, then we receive the potential energy. If to take as argument the generalized velocity, then we receive the kinetic co-energy. On this base is proposed the idea of relativistic kinetic co-energy, which levels certain internal contradictions of gravitation theory.

W artykule przedstawiono zagadnienie estymacji stanu rzeki w oparciu o filtr Kalmana-Bucy oraz integracyjne rozwiązanie z wykorzystaniem sztucznych sieci neuronowych (SSN). Proces estymacji składa się z pomiarów ciągłych i dyskretnych, dla których zaproponowano dwie struktury SSN dla filtracji i predykcji. Przeprowadzono eksperymenty symulacyjne w wyniku, których otrzymano poprawne przebiegi estymaty stanu.

The design method of brush-less generator with permanent magnets on the rotor and U-similar elements on the stator is given. Recommendations are grounded in relation to designing taking into account the features of construction and on the basis of theory of electromagnetic transformation of energy. These recommendations are taken as a basis of project calculation of basic geometrical sizes of such generator.

This paper presents the issues related to the mathematical modeling of organic pollutants present in the river. The models have varying degrees of complexity, ranging from the description of ordinary differential equations, to partial differential equations of hyperbolic type. It also provides an interpretation of their solutions, using the natural specificity of the river, allowing an accurate description of the river a set of ordinary differential equations.. Discusses the problems of river pollution control, taking into account various factors gain control of extortion and various pollutants and their location. The issues raised were used to the idea of solving partial differential equations on the basis of a set of ordinary differential equations. Furthermore, polynomial interpolation was used to create an approximate model biochemically polluted river in the calculations are based on only selected characteristics.
