Coordination method in design of forming operations of hierarchical solid objects
The application of the coordination technology in the design of forming operations is regarded. The coordination design method was developed by using hierarchical systems construction and dynamic systems (by M. Mesarovich and Y. Takahara), numeric positional systems, and aed formal model (by S. Novikava). Solid objects being designed and their forming operations were presented in hierarchical form taking under consideration the objectpsilas structure, its external presentation as the unit in environment system and the environment system construction. All the design and control actions are executed by coordinator on its selection, learning and self-organization layers by one of coordination strategy. Theoretical basis description and computer realization of the proposed coordination technology for the exemplary forming tasks solving are also presented in the paper.
Coordination Technology in the Assembly Operations Design
The application of the coordination technology in the design of assembly operations is regarded. The coordination design method was developed by using hierarchical systems construction and dynamic systems (by M. Mesarovich and Y. Takahara), numeric positional systems, and formal model (by S.

SR topography of plastically deformed Fe-Si bicrystals - observation in situ and post mortem
SR reflection topography was applied to study the interaction of slip dislocations with the grain boundaries in Fe-4at%Si bicrystals deformed by compression. Three experimental settings with either a white or monochromatic beam were used and the corresponding orientation contrast analysed. Dislocation transmission through the grain boundary was observed in bicrystals with favourable geometry of the slip systems.
