Research subject for a potential FP6 project

The first goal is execution of the consequent energy balance of a mechanical subsystems of vehicle or building. Standing the power flows, the energies of the subsystems and the interaction energy according to the physical substance of the problem. A proposal of the method, which allows to specify the subsystem sequences of given system that contribute the most to the transfer of critical nodes.

The next goal is quantitative valuation of possible power flow paths. The percentual distribution of total power flow to all possible power flow paths will be result of computation. From the view-point of power flows, inside conditions of the system will be represented by the directed, edge valuated graph. Then, the relations valid for arbitrary number of subsystems will be derived, those enable a suitable alghoritmization of the procedure and its implementation to the computer
