Title:	LOSSLESS NETWORK COMPRESSION BASED ON TOPOLOGY POTENTIAL COMMUNITY DISCOVERY
Author:	WANG XUHUI
Abstract:	A research of lossless network compression is carried out. To meet the different needs, two approaches of lossless network compression are proposed in this research. One approach, judging importance of the nodes according to their roles playing in the community composition, quantifies the importance of every node in communities, and achieves lossless network compression through layers; another approach, judging importance of the nodes according to the distances from the community representative nodes to them, differentiates the nodes with different distances, and achieves lossless network compression through compression ratio. Comparative experiments show that the two approaches not only can achieve perfect compression ratio, and retain the relationship between the communities, but also can reserve the important nodes or basic community structures during the compression process according to the needs.

Title:	ANALYSIS OF ICSGD AND OSSDL LOCALIZATION ALGORITHMS IN WSN
Author:	LIU YANG, XING JIANPING, WU HUA, XIAO HAIRONG, WU XIAOMING
Abstract:	In our papers before, two three-dimensional localization schemes which are called iterative calculation of secondary grid division localization scheme (ICSGD) and a range free three dimensional optimum space step distance localization scheme (3D-OSSDL) are proposed respectively. In ICSGDLS scheme, forty beacon nodes and five hundred unknown sensor nodes were randomly deployed in a cube, which is divided into smaller cubes twice. The position information of unknown nodes could be got by iteratively calculating the centroid of smaller cubes. However, in 3D-OSSDL algorithm all nodes are randomly deployed in space and forms arbitrary network parameters. By optimizing distances from the network model, the optimum space step distance from nodes to anchors is obtained and the coordinates of all unknown nodes are derived finally. In this paper, comprehensive analysis and comparisons are made by MATLAB software. And by this paper we can find the optimum work status of the two.

Title:	COMPREHENSIVE COMPARISONS OF THREE LOCALIZATION ALGORITHMS USED IN WSN
Author:	MA XIANGXUE, XING JIANPING, LIU YANG, WU HUA
Abstract:	In this paper, we made comprehensive comparisons of three localization algorithms in wireless sensor network (WSN): A localization algorithm based on virtual central node (VCN), an improved 3D node localization algorithm based on virtual central node (IVCN) and an iterative calculation of secondary grid division (ICSGD) localization scheme. VCN and IVCN algorithms are both adapted to the wireless sensor network (WSN) that anchor nodes present an uniform distribution in three dimensional sensor spaces. During the localization process, by deducing a 3D special node, which is called the virtual central node, unknown nodes can compute their own positions automatically. Iterative calculation of secondary grid division (ICSGD) localization scheme could solve the inconsistency between calculation amount and location accuracy. The performance of the localization scheme was evaluated in a series of simulations performed using MATLAB. The simulation results demonstrated that the three schemes outperform in terms of higher location accuracy, and lower location amount.

Title:	MECHANICLA INFORMATION OF FOOTBALL COLLISION DURING DIFFERENT SPEED LAUNCH
Author:	JIANG JIAN-BAO
Abstract:	Football collision is a common phenomenon during football matches, but mechanical approach to study football collision process was quite limited. This study was using force platform and high speed video system to monitor the football collision under low and high speed conditions. The high speed collision was nearly double compared the speed of low collision. But the contact time under these two collision conditions was not discrepancy a lot. We found when the speed increasing, the collision power will increase a lot. Therefore, in the football match, especially the player shots or rescues dangerous ball, if the ball hit directly on one part of human body, it may produce harm to the body even damage. We should do some buffering action to minimize the impact and protect our body. Some meaningful values in this study, were very helpful to football training and relating product development, providing certain theoretical guidance and improve the development of the football sport.

Abstract:	In modern embedded systems, most of them mount with a certain amount of peripherals devices, often a large number of I / O time is consumed in the process of processor access these devices, thereby reducing the overall performance of embedded systems. However, to open up a space in the memory for caching of these device’s data can resolve this problem. UM_BUS (Dynamically Reconfigurable High-speed Serial Bus) with 32 bits wide is the research object of this paper, whose bandwidth can reach 269.5M/s in the ideal condition, but the large number of I/O operations has a serious impact on bus bandwidth utilization. In order to resolve this problem, a data cache mechanism based on the structure and basic theory of cache is designed and implemented for UM_BUS in this paper. After the experimental test, the mechanism is proved to run in the UM_BUS controller driver effectively and improves the bandwidth utilization of UM_BUS significantly, therefore, enhances the performance of the bus to some extent.

Title:	NUMERIC SIMULATION OF MOMENT OF STABILIZING PILE UNDER THE LOCAL LIQUEFACTION BASED ON FINITE ELEMENT METHOD
Author:	LI RONGJIAN, LIU JUNDING, YAN RUI
Abstract:	The evaluation of liquefaction effect on the dynamic moment of stabilizing piles is potentially significant. Based on the dynamic centrifuge modeling of a slope reinforced with a row of copper model pile, this paper not only analyzed the response of dynamic pore pressure, earthquake deformation and macroscopic phenomenon measured in the response of the reinforced slope, but also simulated the response characteristics of dynamic bending moment of stabilizing pile under the condition of local foundation liquefaction by using the dynamic consolidation finite element. Through the comparison of model test and computation, the results show that the local liquefaction in the saturated foundation resulted in the large seismic deformation at slope toe and slope top, and this seismic deformation not only leads to increasing sharply of the dynamic excess bending moment of stabilizing pile, but also makes the post-earthquake residual moment much bigger than the static bending moment before earthquake. So the excess moment of stabilizing pile in liquefiable soil caused by the saturated foundation liquefaction can’t be ignored.

Title:	SELF-ORGANIZING MAP-BASED K-MEANS CLUSTERING FOR STABILITY ANALYSIS OF PRODUCT QUALITY IN PACKAGING IN SEMICONDUCTOR MANUFACTURING
Author:	JIN DING, YONG-ZAI LU, JIAN CHU
Abstract:	The “packaging” plays an important role in semiconductor manufacturing. Among the multiple test-passed steps in packaging production, the step of “wire-bonding” is the most complicated and critical one since there are many tuning parameters, such as force, current and time, etc. needing to be set-up by operators in order to perform good bonding. Several key perform indexes, for example, wire pull, ball shear and ball height, are used to measure the product quality. This paper presents the development of applying SOM (self-organizing map) based k-means to the data-based classification for product quality. Namely, the product quality can be divided into a number of categories in terms of huge historical quality related data. In addition, SOM based K-mean clustering model, algorithms and the case studies with real-production data are addressed. The concluding remarks and future work are given in the final section.

There are many practical applications for restricted adaptive oblivious transfer, such as medical or financial data access, pay-per-view TV, and so on. However, so far as we know, there are only two proto-cols for restricted adaptive oblivious transfers which were both proposed by Herranz [8]. Furthermore, the-se two protocols are very expensive. In this paper, we propose a new protocol for restricted adaptive oblivi-ous transfer by using fully homomorphic encryption. Compared with Herranz’s constructions, our protocol is more efficient in the cost of communication and computation.

Title:	PEDESTRIAN DETECTION BASED ON FOREGROUND SEGMENTATION IN VIDEO SURVEILLANCE
Author:	MING XIN, CAILI FANG
Abstract:	Real-time detection and tracking of moving pedestrians in image sequences is a fundamental task in many computation vision applications such as automated visual surveillance system. In this paper we propose a human detection method based on foreground segmentation, and the detection speed is satisfying for the application of video surveillance. During detection, unlike the exhaustive scan typically used in general human detection systems, in order to avoid scanning regions like the sky, the foreground segmentation stage is firstly implemented in the video surveillance sequences by utilizing Gaussian mixture model algorithm, and then, human detection stage is executed on the regions of interest (ROI) extracted from the video surveillance sequence frame. In contrast with the exhaustive scan without explicit segmentation, our proposed approach can meet the real-time requirement. Carefully designed experiments demonstrate the superiority of our proposed approach.

Title:	AN APPROACH TO GENERATE TESTS FOR MULTIPLE VICTIM LINES OF CROSSTALK FAULTS IN INTEGRATED CIRCUITS
Author:	PAN ZHONGLIANG, CHEN LING
Abstract:	The continuous progress in circuit technology offers the opportunity to design circuit chip with high integration density. The parasitic capacitances among the signal lines in circuits are increased; this results in the arising of circuit noises such as crosstalk. The coupling effects of a crosstalk occur between the aggressor lines and victim lines. If the strength of the aggressor line is large, then it may produce interferes for a lot of adjacent lines. Therefore, the type of the crosstalk fault consists of an aggressor line and multiple victim lines are investigated in this paper. A new test vector generation approach is presented for the crosstalk faults with multiple victim lines. The approach uses a lot of structure characteristics of the circuit under test, performs the partition of circuit cones, path selections, value implications of signal lines, etc., and the test vectors are produced by forward tracing and backtrack tracing. The experimental results for a lot of digital circuits show that the test vectors of the crosstalk faults with multiple victim lines can be generated by using the approach proposed in this paper, and the feasible fault coverage can be obtained.

Title:	EQUIVALENCE CHECKING OF COMBINATIONAL CIRCUIT USING CHAOTIC PATTERN SIMULATION AND BINARY DECISION DIAGRAMS
Author:	ZHONGLIANG PAN, LING CHEN
Abstract:	With the increase of complexity of circuits, guaranteeing the correctness of design becomes extremely important. A new equivalence checking method is presented in this paper for the verifications of combinational circuits; the method uses the chaotic pattern simulation to find a lot of equivalent nodes, which results in that the scale of the composite circuit is reduced. The equivalence checking of two combinational circuits is carried out by constructing a BDD which is corresponding to a circuit being made up of the composite circuit and interface circuit. If the BDD is a constant 0, then the two combinational circuits are functional equivalence, the two rest circuits are not equivalent. The experimental results for a lot of circuits show that the more accurate equivalent nodes can be obtained by using chaotic pattern simulation in this paper than the random pattern simulation, and the equivalence checking method presented in this paper is able to verify the combinational circuits in shorter time.

Author:	HAN YAN-CHENG, XING LI-TING , MA ZHEN-MIN, JIAO YU-FEI
Abstract:	Groundwater source heat pump technology is an energy-saving method to use the groundwater heat energy resources for heating in winter and cooling in summer. It is important to comprehensive study the process of groundwater thermal transport of winter combined summer GWSHP under the continuous running condition. In this paper the simulation models have been proposed using winter-only and winter combined summer GWSHP respectively, and computer simulations were carried out. The results show that the temperature will decrease year by year if using winter-only GWSHP. The groundwater temperature change is smaller using combined GWSHP than using winter-only GWSHP. In summer, the winter combined summer GWSHP can use the cooling storage recharged last winter and in the winter it can use the heat storage recharged last summer. The winter combined summer GWSHP can improve thermal efficiency in the winter and enhance the cooling effect in summer.

Author:	XUNGAO ZHONG, XIAFU PENG, XUNYU ZHONG
Abstract:	The visual robust tracking is an acid test for existing methods since the target with large-dynamic-change scenarios. Specifically, this paper presents neural aided Bayesian filtering scheme which is based on Monte Carlo resampling techniques associated with lower particles hypothesis to addresses the computational intensity that is intrinsic to all particle filter (PF) approaches, including those that have been modified to overcome the degeneracy of particles and improve the diversity of particle samples. Performance and tracking quality results for severe-dynamic target tracking experiments demonstrate that the Bayesian filtering deteriorated error caused by constrain the number of particles required which was compensated by a RBF neural network, with high accuracy and intensive tracking performance for unconstrained abrupt motion only require lower particles compare with SIR Bayesian filtering, meanwhile, the proposed method is also with strong robustness for different number of particles.

Abstract:	Deformable model is one of interest topic in biometrics. The deformable model applications have been used to detect objects included facial sketch feature images. Many methods have been discovered and developed to detect objects of deformable. However, any method can solve a problem, but raises other issues. Popular method to solve the deformable object is Active Shape Model. It is the most used to detect facial feature, but it has weakness. This method is very depended on the shape initialization. If the movement direction is not covered by training sets, then the landmark movement will be move to the undesirable direction. In this research, we proposed method to create a new modeling of the landmark movement based on the previous movement results. Four algorithms are used to improve the landmark movement when the detection process. The experimental results show that our proposed method produces the average of detection accuracies more than 90% for all scenarios.
