Butt joints of aluminum foam were made by three different brazing processes including brazing with multilayer filler metal in high vacuum of 10−3 (Pa) degree, brazing with multilayer filler metal in low vacuum of 1 (Pa) degree and brazing with monolayer filler metal in high vacuum of 10−3 (Pa) degree. The macrostructure and microstructure characteristics and bending strength of the joints were investigated and compared. The results indicate that the brazed specimen can achieve a satisfactory joint when brazed with multilayer filler metal in high vacuum. The bending strength of the joint is higher than that of the base metal. However, the bending strength of the joint is obviously lower than that of the base metal when brazed with multilayer filler metal in low vacuum, while it is slightly lower when brazed with monolayer filler metal in high vacuum.

Adaptive Support-Weighted method (ASW), which sets a support weight for each pixel, based on color similarity and geometric proximity, makes an accurate disparity map. To keep the change of disparity align with edges of the reference image, we apply guided filter to smooth the cost volume generated by ASW, and use left-right consistency (LRC) to detect occlusion pixel. The experimental results demonstrate that the accuracy of disparity map has been improved.

Adaptive Inverse Control(AIC) based on Recursive Least Square(RLS) is applied in Control Loading System(CLS) of Flight Simulator(FS) .The algorithm was used to improve position tracking accuracy as an inner loop of CLS. This paper presents the implementation of a rapid prototyping control system based on RAT-LAB simulation environment, which involves the design of AIC and RLS algorithms using MATLAB/Simulink blocksets. The effectiveness of AIC was verified by mean of the analysis of the experiment results such as the comparison of reference signal and position output response signal, the change of frequency bandwidth. Finally, the accuracy of identification was pointed out via experiment that is a critical factor of the AIC.
