The spatial distribution of evapotranspiration is often obtained from dual source energy balance models forced by surface temperature data. use multi-angular remotely-sensed thermal data in such methods makes them susceptible to directional-anisotropy/thermal-radiation directionality effects that may result the satellite's position, relative Sun, at overpass time. It therefore important have th...

Flow in the first two-stage of V 94.2 gas turbine is simulated numerically. In this turbine, the second stator is clocked relative to the first stator to different positions. Steady-state analysis was carried out by varying the circumferential relative position of the consecutive stator vanes to study the effects of the clocking on turbine performance. A density based compressible inviscid ...

The location of a remembered reach target can be encoded in egocentric and/or allocentric reference frames. Cortical mechanisms for egocentric reach are relatively well described, but the corresponding allocentric representations are essentially unknown. Here, we used an event-related fMRI design to distinguish human brain areas involved in these two types of representation. Our paradigm consis...

A modified two-element Yagi-Uda antenna with tunable beams in the H-plane (including four significant beams: forward, backward, omni-directional, and bi-directional beams) is presented. These tunable beams are achieved by simply adjusting the short-circuit position of the transmission line connected to the parasitic element. The principle of operation is investigated by examining the current re...

This paper proposes a novel foot-pad omni-directional locomotion interface, establishes planar walking algorithm for it in detail. The proposed locomotion interface allows users walking omni-directionally in a virtual environment, which can improve users’ immersion characteristic significantly. The established walking algorithm explains the relation between the motion of foot-pads and the posit...
