To reach higher compression ratios without perceptually degrading the reconstructed signal, the properties of the human visual system (HVS) need to be better exploited. Research simulated the sensitivity of HVS with the just-noticeable-distortion (JND) model, which describes the perception redundancy quantitatively. This paper proposed a new JND model in multiview video coding (MVC) which explored the property of HVS to stereoscopic masking effect. The proposed model contained the spatial JND, temporal JND and the JND in depth. A novel asymmetric stereoscopic video coding method was proposed based on the new JND model. For each macroblock (MB), the quantization parameters (QPs) were optimized adaptively based on the new JND. Compared with the original JMVC scheme without JND, our method gets remain perceptual quality and save bits averagely 24.18%~36.24%.

Anti-violent rocket on small UAV creatively combines the anti-riot shell with the UAV,utilizing the theory of rocket lanching,realizing that Anti-violent Shell is launched far in the sky.It is significant for CAPF to realize variety of targets battle in the emergency and mission. This paper focuses on sumulation and testing of anti-violent rocket engine on Small UAV,and the flight test-fired experimental of engine is carried on with control system,which demonstrates its feasibility.

HIP (Host Identity Protocol) is the current standard for supporting global mobility, however the performance degrades to support micro-mobility. In accordance with the idea of micro-mobility of mobile IP, the mobile node range of motion is divided into different administrative areas, different management areas correspond to different RVS (Rendezvous Server), we can get a mechanism to support micro-mobility management. Theoretical analysis shows that such mechanism than traditional HIP has an advantage in handoff performance, not only can reduce the handoff delay, packet loss rate and increase the success rate of handoff, but also good support micro-mobility.
