Identification of perimeter events enables smarter perimeter security systems. This paper presents a multi classifier. Support Vector Machine (SVM) and Artificial Neural Network (ANN) are the bottom to build the classifier. The top level employs voting mechanism to identify intrusions, taking time evolution characters into account. In addition, to make the(More)
The block motion estimation process is an integral and important part in the current video coding standards. However, the current algorithms for the block motion estimation process either have a large computational complexity, or have a poor accuracy. The UMHexagonS algorithm is recommended for the implementation of H.264 for its relatively good(More)

In this paper, a new method combined fuzzy theory and neural network was proposed, which was employed to solve multi-maneuvering target tracking. Multi-maneuvering target tracking is a process, which manages measure information to maintain currently state estimate. The fields of fuzzy sets and neural network have made rapid progress in recent years. Neural(More)
The characteristics of the interaction between reserpine and bovine serum albumin (BSA) were studied by fluorescence, UV-vis absorption and Fourier transform infrared (FT-IR) spectroscopy. Spectroscopic analysis revealed that fluorescence quenching of BSA by reserpine was through a static quenching procedure. The binding constant K(A) of reserpine with BSA(More)
With the rapid growth of e-commerce and user-generated content online, the increasing product online reviews have significant influence on both buyers and sellers. However, among the thousands of online reviews, only the reviews of high-quality matters to the market, thus quality reviews detection rises in response to the requirement of retrieving authentic(More)
Under the hypothesis of underlying asset price with long-range correlations and jump in short time, the stock price model is constructed driven by fractional Brownian motion and jump process. Then an analytic solution for European option is obtained by quasi-martingale method in the environment of fractional Brownian motion and Poisson process. For the sake(More)
Under the hypothesis of underlying asset price with long-range correlations and jump, a new framework for pricing European option is developed in a mixed fractional Brownian motion and double exponential jump- diffusion model with stochastic volatility and stochastic interest rates. An analytic formula for pricing European option is proposed. The(More)

At present, many transformer substations had installed all kinds of management information system, these systems were usually independency and redundancy, so they can not share computer resources each other. A support system was developed, which based on the .NET framework. This system can help to manage all kinds of data by using the computer database at a(More)
