Sustainable development was defined by the Bruntland Comission as a 'development that meets the needs of the present without compromising the ability of future generations to meet their own needs' (WCED1 , 1987, p. 8). In the report 'Our Common Future' the Bruntland Commission proposed policies for a 'World Programme for Change' (WCED, 1987). At the UNCED2 , conference in Rio 1992, proposals were
A new convergence criterion for nonlinear systems was recently derived by the first author. The criterion is similar to Lyapunov’s second theorem but differs in several respects. In particular, it has a remarkable convexity property in the context of control synthesis. While the set of control Lyapunov functions for a given system may not even be connected, the corresponding set of “density” funct

The modern requirements on power transmissions focus on energy efficiency, low noise and dynamic vibrations, and power density. In order to meet these requirements, the gear wheels must be manufactured to very high precision. Additionally, it should be economical to manufacture these gears within the tight requested tolerances. Gears manufactured within automotive, truck, and construction equipmen
