Abstract: Radio tomographic imaging as a coarse computational imaging method has attracted much attentions due to its potential applications in human surveillance. It utilizes the shadow fading characteristics of radio signals among wireless sensor network nodes to infer the targets' localization. The recovery process involves a large number of scanning links, which brings heavy burdens on node energy, communication routes and data storage. In general, there is a small number of targets and could be seen as a sparse signal compared with the original high-dimensional space. Hence, the key of scene recovery is the effective links selected. As the continuation of the previous part of work, this part of paper presents experimental studies indicate the proposed method is able to obtain better accuracy under the same number of measurements compared with the existed method. Numerical applications of proposed model are illustrated as well.

Abstract: Because of the drift which exists in sequence image of prostate DWI (Diffusion Weighted Imaging), the global ant colony algorithm is introduced into the paper for registration optimization. The paper introduces an ant colony algorithm for continuous function optimization, based on max-min ant system (MMAS). This paper controls the transition probabilities and enhances the abilities of ants seeking globally optimal solutions by adding an adjustable factor in the basic ant colony algorithm and updating the local pheromone and global pheromone. Experimental results verify the effectiveness of the algorithm.

Abstract: Biochemical indicators have the role of monitoring for competitive sports level data, the use of biochemical indicators to assess the fitness and health status of athletes, the results is more accurate. In this paper, a system designed to provide technical support for the athletes and biochemical indicators of management systems development. First, choose a representative biochemical indicators, and indicators are described; then, processed the database logical structure design, including athlete information, sample information, biochemical markers, and other related fields; finally, functional design, including data entry, data modification, data query, data reporting, system management and other main function module. Using results of this study can give full play to the role of technology in competitive sports, to achieve scientific training.

Abstract: This text passes according to the design of the tool machine reformation spindle, to five axis bridge type compound material machining center motorized spindle design reformation, and design to transfer board, finally success apply to engineering.

Abstract: Research silymarin food security through animal experiments. Acute toxicity test, mouse bone marrow micronucleus test, mice sperm abnormality test results were evaluated. Male and female mice by oral maximum tolerated dose (MTD) are more than 20.0g/kg body weight, according to the acute toxicity grading standards, which are non-toxic level. Mouse bone marrow micronucleus test, mice sperm abnormality test and genotoxicity test were negative. Showed that silymarin is a food safety component.

Abstract: Corn gluten were steeped with different chemical reagents, 2%urea, 5%tween80, 5% NaCl, 2%L - cysteine, using distilled water as control. Intermolecular forces in corn gluten under different reagents were analyzed using the amount of free starch measuring by iodine calorimetry. By the light microscope, intermolecular structure transformation in corn gluten was analyzed before the treatment and after. The results show that Urea, twain, NaCl, and L-cysteine all can make the starch that closely combined with protein migrate away, in which the effect of L-cysteine and NaCl were better, releasing more free starch. It is found through microscopic observation that the starch granule existing in corn gluten is small granule from cutin endosperm, and microscopic observation results consistent with the free starch results. By analysis of the amount of free starch and the microscopic structure change of corn gluten and the mechanism of measuring intermolecular forces with the chemical reagent, it is demonstrated that disulfide bond and electrostatic attraction were main intermolecular forces in corn gluten, which was the main reason for the search combining with the protein .The effect of intermolecular hydrogen bonds and hydrophobic interaction were weaker.

Abstract: The new energy electric bus has already been used for many years; however, it is also not strange that there are problems in the actual operation process. Base on the running status of new energy vehicles during the early stage, this article provides some opinions on problems of using electrically driven compressor, which is mainly stated oil carryover and vibration noise of several kinds of electrically driven compressor and enumerated the partial performance of the compressors. After all, the behavior of compressor will not only directly affect the braking safety performance, but also had a greater influence on the Sequential maintenance costs.

Abstract: Against the problem that the existing MPPT control algorithms of PV array have difficulties to balance both of the control accuracy and searching speed, this article presents a golden ratio optimal gradient MPPT algorithm based on the traditional optimal gradient MPPT control algorithm. The algorithm is an optimal gradient control algorithm of variable step size, it has an advantage over the traditional fixed step optimal gradient algorithms on tracking the maximum power point. The experimental results show its superiority in the searching speed and control accuracy by modeling and simulation on PSCAD.

Abstract: According to the problem of power network visualization system which has the poor effect in 2D style and the limitation of visual effect in 3D style, setting geographical SVG as research target, and introducing virtual reality platform as basic simulation environment, designing and realizing power system SVG 3D render engine named PSSRE. The design and implementation of parsing module and rendering module are analyzed as well as three-layer render architecture and representation method of layered grid structure. The results show the efficiency of PSSRE.

Abstract: s. The electronic technology is a key component of digital high-resolution ADC converter.
