"ABSTRACTThe presented study is focused on experimental investigation of a boundary layeron a flat plate in an adverse pressure gradient. The flat plate is placed in a regular flow, thepressure gradient is generated by the plate inclination. The preceding studies deal with thestructure of the wake behind the plate, the presented study concentrates on the flow structureclose to the suction surface of the plate. The dynamical behavior of the flow structures is studiedin details with respect to the topology in the streamwise direction. In spite of the fact that thetime-mean flow field is close to 2D, more or less constant along the span, the instantaneousstructures topology is fully 3D. Rather oblique structures are detected instead of those orientedin the streamwise direction. The patterns are travelling in the streamwise direction along theplate."

"An introduction to aspects of the theory of dynamial systems based on extensions of Liapunov's direct method. The main ideas and structure for the theory are presented for difference equations and for the analogous theory for ordinary differential equations and retarded functional differential equations. The latest results on invariance properties for non-autonomous time-varying systems processes are presented for difference and differential equations."
