Abstract: In this article, analytical solutions of the normal and tangential impact of half-spaces at low velocities are formulated. After a brief introduction, a classification of contact problems is ...

Abstract: Traditionally, speed control of hydrogenerators has been implemented by analog proportional-plus-integral control of speed error. With digital controllers, nonlinear, adaptive control strategies may ...

Abstract: The flow energy loss (head loss) through a cast of canine central airways is found to be nearly independent of flow direction. By contrast, head loss in geometrically-simpler branching sections ...
