During the transformation of society, accompanied not only by socio-economic decline, but also unfavorable indicators population reproduction, issue reducing reproductive losses and maintaining viability offspring at all stages ontogenesis. Purpose - to investigate condition dynamics main components in Ukraine. Materials methods. A comprehensive retrospective analysis assessment their Ukraine f...

The impact of granular microstructure on permanent magnets eddy current losses is investigated. A numerical homogenization procedure for electrical conductivity defined. Then, an approximated simple analytical model the homogenized able to capture main features geometrical and material dependences derived. Finally, analytic calculations are given, two asymptotic expressions in stationary conduc...

due to the increasing interest on renewable sources in recent years, the studies on integration of distributed generation to the power grid have rapidly increased. in order to minimize line losses of power systems, it is crucially important to define the size and location of local generation to be placed. minimizing the losses in the system would bring two types of saving, in real life, one is ...
