Space membrane reflector is very promised for optical quality application with the merits of ultra-lightweight and flexible. In order to improve the surface precision of membrane reflectors
the formation and surface shape error of a membrane at uniform load are studied based on the henky-cambell equations of circular membrane. The ANSYS software is used to build an optimization model of membrane reflector surface shape
in which the yield strength is the state variable
the surface load on ten concentric annular regions of the mirror is the design variable
and the minimum RMS between ideal surface and mirror surface is the target function. and the theoretical and experimental result show that RMS and PV of the optimized surfaces are reduced respectively than those before optimization. In a word
this paper offers the theoretical and experimental basis of the polyimide membrane reflector. 2011 IEEE.

Crowd panic behavior detection is an important task in video analysis and event recognition
whose purpose is to detect when the panic behavior happened and alarming the abnormal event timely. In this paper
the crowd is regard as a fluid
and the crowd motion is described by four fluid kinematic features (divergence
vorticity
gradient tensor invariant and rotation tensor invariant). To discriminate the panic event from normal crowd behavior
an information entropy is calculated as a high level feature based on the fluid kinematic features. Experimental results show that the entropy raised dramatically once a panic event happened.

In order to design and manufacture more excellent airborne photoelectric stable turret
modulus of elasticity of 213 GPa and thermal expansion coefficient of 7.9106/K. The frame has decreased the maximum deformation by by 60% and increased the fundamental frequency by 65% as compared with those of aluminum alloy materials
a new type of aeronautical material-particulate reinforced aluminum matrix composite (SiC/Al composite) is investigated. Several crucial technologies
respectively as shown by finite element analysis results. Those are confirmed by vibration test furthermore. Therefore
such as pressureless infiltration technology
a significant lightening effect is achieved and the thermal control load is also reduced. The test result indicates that the stable accuracy of the system achieves 19.8rad and the optical-axis parallelism of pay load is 0.1mrad. The research applies the SiC/Al composites to airborne photoelectric platforms
interface reaction controls and plate's welding are systematically studied. Then
which makes a effective exploration for the new aeronautical material's application. 2011 IEEE.
using SiC/Al composites
the airborne photoelectric stable turret frame is successfully prepared in density of 2.94 g/ cm3
