Titanium alloys have good mechanical properties and organizational stability. However, due to the larger viscousity of titanium, a reasonable choice of the characteristic parameters of oilstone will directly affect the quality and efficiency of honing processing. This article solved multi-objective problem using artificial neural network with fast convergence and high precision. Based on a comprehensive analysis of the relationship between the workpiece material, materials status, surface hardness, the required surface quality and various parameters of oilstone, the improved artificial neural network algorithm-GCAQBP was adopted, through coding optimization of input and output parameters, model of intelligent choice of oilstone’s parameters was constructed about titanium alloy cylinder honing processing. Through experimental studies, it is shown that the intelligent model can choose quickly with high reliability compared with the traditional experience.

IPTV is a new TV style. IPTV STB is the key device of IPTV system. In this paper, we will select the ARM9E as the embedded chip. We designed a new IPTV STB based on Android system. The system structure chart of STB may be helpful for the IPTV system.

The luminance difference is one of the important factors of stereoscopic television. In this paper, according to the characteristics of stereoscopic television glasses, we use white window signal and black field signal to measure luminance difference of 3D TV. We adopt the left and right eye channel individually tested brightness. We chose the center point of stereoscopic television as measuring point. And then, we select a few of stereoscopic television as testing model. The proposed method may be helpful for the quality evaluation of stereoscopic television.

In combination with the installation of radar capture camera support, the maximum offset, the rod being considered by external forces, external forces such as wind effect will produce a non-directional bend, the stability of the camera will installand capture some of the impact. Solving method in the article is a combination of the equivalent moment method to seek to solve its offset. the rod is divided into equal finite element. the equivalent moment method to calculate the relative rotation of each section. Find the maximum deflection of the rod.
