In this paper, we present a novel data structure representing the environment with occupancy grid cells while each grid map is associated with a set of line features extracted from laser scan points. Due to the fact that line segments are principal elements of artificial environments, they provide considerable geometric information about the environment which can be used for enhancing the accuracy...
Numerical results in this work demonstrate that the flow around an oscillating electrode of a micro electrostatic comb drive is quite different from a Stokes flow. A vortex is observed in the region between the electrode and the substrate. This vortex slows down the fluid velocity and significantly increases the damping. Squeeze damping and viscous damping are important energy dissipation mechanisms...
