We study the dynamics of an electrostatically driven impact microactuator. Impact between moving elements of the microactuator is modeled using the coefficient of restitution. Friction between the microactuator and its supporting substrate is modeled using the Amonton-Coulomb law. We consider the bifurcations under changes in the driving voltage and frequency. Grazing bifurcations introduce dis...
Most qualitative simulation techniques perform simulation at a single level of detail highlighting a xed set of distinctions. This can lead to intractable branching within the behavioral description. The complexity of the simulation can be reduced by eliminating uninteresting distinctions. Behavior abstraction provides a hierarchy of behav-ioral descriptions allowing the modeler to select the a...
Abstract: In this paper, a chatter free sliding mode control(SMC) strategy for chaos synchronization is proposed to the nonlinear uncertain chaotic systems in the presence of unknown bounded uncertainties and external disturbances. The sliding mode surface with differential operators is introduced to divert the discontinuous function swith term into the first derivative of the control input, an...
Chatter is the main problem that limits application of industrial robots in field machining process. It critically important to establish an adaptive chatter detection solution for robot process and realize online chatter. However, different from machine tool chatter, robotic more complex be detected due variable stiffness characteristics weaker normal robot, existing literature has less resear...
Adrenomedullin (AM) is a vasodilating hormone secreted mainly from vascular wall, and its expression is markedly enhanced after stroke. We have revealed that AM promotes not only vasodilation but also vascular regeneration. In this study, we focused on the roles of AM in the ischemic brain and examined its therapeutic potential. We developed novel AM-transgenic (AM-Tg) mice that overproduce AM ...
