[Documents] 0712.3985 DL : 0: We obtained the energy transport velocity distribution for a three dimensional ideal cloak explicitly. Near the operation frequency, the energy transport velocity has rather peculiar distribution. The velocity along a line joining the origin of the cloak is a constant, while the velocity approaches zero at the inner boundary of the cloak. A ray pointing right into the origin of the cloak will experience abrupt changes of velocities when it impinges on the inner surface of the cloak. This peculiar distribution causes long time delays for beams passing through the ideal cloak within a geometric optics description.

[Documents] Hao-Cheng_IJHMT10_micro.droplet..movement DL : 0: Based on a macroscopic force balance analysis, an alytical solution in terms of dynamic contact angle is obtained for steady velocity of a droplet driven by a shear flow and moving on the hydrophobic wall of a microchannel. The multiphase free-energy 3-D Lattice Boltzmann method (LBM) is applied to simulate the deformation of the droplet in order to obtain the dynamic contact angle of the moving micro-droplet in the analytical solution. The droplet velocities predicted by the analytical solution are found in good agreement with the LBM simulation results.-Based on a macroscopic force balance analysis, an analytical solution in terms of dynamic contact angle is obtained for steady velocity of a droplet driven by a shear flow and moving on the hydrophobic wall of a microchannel.

A novel five-axis interpolation method is proposed to ensure that maximum velocity constraints for each axis can be satisfied. The geometric error model, including lead screw, straightness, angular and squareness errors is built to analyze the volumetric errors within the working space. The model which includes rigid body motion, friction model and servo control loops is utilized to evaluate servo dynamics and non-linear effects. The errors caused by the locations, servo dynamics, and friction effects are integrated into the VMT simulation program. Simulation results of TCP trajectory are represented by small line segments to generate NC codes. Then the NC codes are fed into VERICUT software to perform virtual cutting.)
