The project proposed is in accordance with the three basic long-term directions of research activities (7 priorities) approved by Government of the Czech Republic in 2005. They are listed as follows: - Energy resources (Support of sustainable long-term insurance of energy resources), - Materials research, - Competitive mechanical engineering.
