Flow-based microfluidic biochips are attracting increasing attention with successful applications in lab-on-a-chip experiments and point-of-care diagnosis. Physical design for flow-based biochips determines the number of flow-channel intersections, and thus affects the number of microvalves. As reducing microvalves will significantly improve the overall design quality and reliability, physical design...
As the first official published commercial block cipher standard of China, SMS4 has been widely used in local area wireless product. Although the algorithm is proved to be secure enough mathematically, when implemented in hardware, it is vulnerable to differential power analysis (DPA), especially using chosen plaintext method. In order to discuss countermeasures against DPA, we present a secure circuit...
Frequent item set mining is an important researching area in data mining and Eclat is a typical and high performance frequent item set mining algorithm. However, the large numbers of sorted-set intersection computation in the algorithm limit the performance of the algorithm seriously. FPGA is a low-power and high-performance computing platform that has been applied to accelerate parallel data mining...
Advance of positioning technology have enabled mass trajectory data of moving objects obtain more convenient. These moving objects always exists special behaviour correlation on spatio-temporal characteristics, and this information is important in some domains, such as prisoner monitoring, factory management, and the study of social behaviour. Many studies have focused on relative motion pattern mining...
The algorithm based on local binary pattern algorithm, direct linear discriminant analysis and waterlet transform can extract the multi-scale feature of the human ear image. The irrelevant of the gray scale integer transform and the local texture feature extracting performance make the local binary pattern algorithm have great advantage in ear image feature extraction. The two dimension waterlet transform...
Because of the high computation demand for multimedia applications like video decoding, there is a need to develop flexible and high performance reconfigurable computing architectures. Taking video decoding algorithm as an example, we propose a reconfigurable computing realization solution of multimedia application. Based on the analysis of parallelism in video decoding algorithm, a hardware platform...
WIA-PA is a standard of wireless networks for industrial-process automation, which is proposed by Industrial Wireless Alliance of China. Network manager is an integral role of the WIA-PA network. In this paper, we first look closely into the architecture of WIA-PA and the responsibility of network manager. More specifically, we set our focus on the schemes and algorithms involved in the process of...
In this paper, by virtue of the methods which comes from intersecting and combining differential geometry with wavelet theory, and this method belong to us. We extend the two-direction multiresolution and the two-direction Mallat Algorithm to the theory on the special differential manifold - compact Lie group, our work lay a foundation for the further study wavelet theory on compact Lie group.
Linear array antennas (LAA) synthetic aperture radar (SAR) three-dimensional (3D) imaging has received a vibrant identification in recent years. This paper proposes a digital-beam forming (DBF)-based three-dimensional imaging algorithm for linear array antennas downward-looking synthetic aperture radar with single-transmitting and multiple-receiving (STMR) configuration. To establish the radar echo...
This paper proposes a structure that automatically analyzes the parameters of Chinese test items. This structure utilizes latent semantic analysis (LSA) to analyze the relationships of keywords among all test items in an item bank. It also uses the similarity measure to calculate the similarity degree of keywords. We also propose an algorithm, which is similar to the graph-theoretic algorithm, for...
A new approach for lossless compression of medical images has been proposed. After preprocessing, the image is split into bit planes to which the compressed technique is applied. These bit planes can be expressed as ordered binary decision diagrams (OBDD) and coding. This approach compared well with WINZIP in terms of compression ratio.
To adjust the traffic burst rate and support dynamic service flows, a multi-service token bucket algorithm was proposed to quality of service architecture in cable modem of HFC access network, based on a token assignment module between token generator and bucket, and polling policy. The acceptance test plan, defined by Cable Television Laboratories, was used to analysis the impact of queue depth on...
