In this paper, a tabu-based variable neighborhood local search (TBVLS) is proposed to solve the n-vehicle exploration problem (NVEP), in which a fleet of n vehicles' trip sequence is determined so as to ensure one of the vehicles visits the farthest distance. In TBVLS, tabu search is employed to conduct iteratively local search around the solution space, which is incorporated with three variable neighborhood...
In the work a microelectromechanical systems (MEMS) based in-situ tensile test for germanium nano-bridge in transmission electron microscope is presented. With a carefully designed electrostatic actuator, germanium nano-bridge can be stretched stably at a speed rate less than 0.05% per step in strain. Assisted with the selected area electron diffraction (SAED) images, Poisson's ratios measured from...
We present a novel experimental method for observing the lattice behavior of single crystal silicon (SCS) nanobeam in process of tensile testing. A TEM in-situ nanobeam tensile testing device has been fabricated and the lattice parameters of SCS nanobeam of different tensile stress have been measured using selected-area electron diffraction (SAED). The results suggest that the trends of the lattice...
