A CFD study of the flow through vibrating screens has been conducted with moving body method of PHOENICS. The flow fields around the static and vibrating screens were calculated with laminar and turbulence models respectively, and the pressure-drop coefficients for both states were obtained. It was found that the flow field became very complex and vortex and backflow were produced because of the motion...
Based on direct sequence spread spectrum code and varies frequencies, the terrestrial pseudo ranging system have high precision and strong anti-jamming capability and could enhance the navigation accuracy of aircraft by fusion with Integrated Navigation System (INS). A fusion method of pseudo-range measurements and inertial sensor data in INS/Pseudo-Range navigation system was proposed in this paper...
A passive acoustic localization method is proposed to estimate the position and bearing of a moving target whose acoustic energy emissions are received by a ground-based array field. The basic array of this array field is a particular type of planar array consisting of two orthogonally orientated linear subarrays with a common sensor at the center. This technology overcomes the ambiguity of linear...
