Opis:: An inertially-driven system that slides on a rough horizontal plane due to periodic oscillations of two internal bodies is studied. Three-phase internal motions with piecewise-constant relative accelerations are considered. It is shown that an always forward motion of the robot can be achieved. The effect of the model parameters on the displacement and average velocity of the system is analyzed.

Opis:: A computer program for topological optimization of a rotor for vertical axis wind turbines of various type is presented. The tool is based mainly on two external modules: the GMSH mesh generator and the OpenFOAM CFD toolbox. Interpolation of rotor blades geometry and computational model of the airflow through a turbine are briefly discussed. Moreover, a simple optimization algorithm is described. Exemplary results for a H-type rotor are presented. Finally, potential directions for the software development are indicated.

Opis:: A problem of steady-state incompressible fluid flow through a fibrous cylindrical filter is considered. The pressure field is obtained by applying the method of fundamental solutions which gives continuous function in the filter region. The components of filtration velocity are calculated from the appropriate derivatives. In numerical examples, various types of the filter are considered and some computational issues are discussed. A simple algorithm for achieving the optimal pseudo-boundary location is used, within the framework of the method of fundamental solutions, by minimizing the maximum absolute boundary error. Optimization results for various numbers of source points and collocation points are compared. The variation of total discharge with the inlet size is shown.
