With the recent development in mobile computing devices and as the ubiquitous deployment of access points(APs) of Wireless Local Area Networks(WLANs), WLAN based indoor localization systems(WILSs) are of mounting concentration and are becoming more and more prevalent for they do not require additional infrastructure. As to the localization methods in WILSs,(More)
Lattice Boltzmann method (LBM) has become an alternative method of computing a variety of fluid flows, ranging from low Reynolds number laminar flows to highly turbulent flows. For turbulent flows, non-uniform grids are preferred. Taylor series expansionand least-squares-based LBM (TLLBM) is an effective and convenient way to extend standard LBM to be used(More)
In this paper, a new design of microstrip patch antenna based on grid structure in the Ka-band is proposed which can realize optical and microwave coaxial detection. Both the patch and ground board is designed into dense grids, at the same time, using the transparent glass as the medium plate. As is shown in the simulation results, in this concerned wave(More)
