In order to tackle so-called “resource starvation” problem, this paper introduces a number of load balance strategies, and presents a dynamic feedback-based load balance strategy. By experiments, feedback-based load balance strategy plays a significant role in circumstances of different nodes and diverse network services.

Grey prediction algorithms are studied in this paper. In GM (1,1) model, development coefficient a and grey action quantity u are two key parameters which have a great impact on prediction system. In traditional methods, these two parameters are obtained by a least squares method with high computation overhead and large prediction error. This problem is discussed in this paper and a grey prediction method called PSOGP is proposed. Based on the GM (1, 1) model, PSOGP uses a particle swarm optimization algorithm to solve the two parameters. Simulation results show that, comparing with the classic GM (1,1) model, the accuracy of PSOGP is greatly improved.

This paper introduces a multi-task programming process in MCS-51 system. The main task processing strategies and kernels of multi-task operating system MCS-51 are analyzed in the paper. On this basis, a multitasking example is designed and realized. The example can be easily transplanted into other applications, and has typical significance to the design of complicated multitasking system.

As one of the outstanding enterprise software firewall, ISA Server can screen the data of all the four-levels of TCP/IP. It can also protect the security of enterprise network and improve the access speed effectively. In this paper, we study the ISA enterprise application and present the specific implementations.

The operator can complete a basic remote control robot movement and the movement to avoid obstacles by the client platform. The experimental results have some practical value to the research of the remote operation of robotic systems.

With the increase of computer online teaching and application, the transmission network data security issues become more important. Online teaching application systems require high level security. Combining with network data transmission security, the paper demonstrates the design and implementation of digital signature based on JAVA.

This paper introduces the application visualization theme surveillance technology application of EMS system. The application of 2d and 3d visualization technology for data display used in EMS is discussed, including bar chat, pie chart, flow line, contours, cylindrical/cone, space connecting line, etc. Based on this, the concept of visualization theme is proposed. And the realization examples of some theme such as voltage, tide, equipment load rate, N-1 analysis results are given. The practical application show that the visualization theme is surveillance and helpful for dispatch personnel to find and solve problems.

The core of making model for lexical analyzer by rule grammar is making lexical model by rule grammar. The process of making lexical model by rule grammar and constructing lexical analyzer based on the lexical model is described with PL/0. The working process of the lexical analyzer made by this method is analyzed with an example. The method of making lexical analyzer based on the lexical model is easier and efficient.

The thesis introduces the basic theory of wavelet transformation and some methods of image fusion. It focuses on the analysis of the image fusion based on wavelet transform. It compares three kinds of image fusion methods (simple image fusion, image fusion based on tower decomposition, image fusion based on wavelet transformation) on left and right wall of adit. Experimental results show that the application of wavelet transformation in image fusion is practical, effective, and it has a practical value and a good application prospects for wavelet transform in digital image fusion.

CRC algorithm is a commonly used algorithm of the wireless MESH network technology. An improved CRC algorithm is proposed, which enhances the processing speed and retains the advantages of the original algorithm. The algorithm finds a balance point between the memory occupancy and the processing rate, to make it more suitable for high speed communication in wireless MESH network.

With the popularity of mobile communication day by day, the growing trends of new customer is not so strong. Meanwhile, the intense competition between Mobile communication and Telecom is more and more fierce. It is an imperative problem to maintain the present customers and recommend customers with new suitable tariff and new business. The paper expounds and illustrates how to realize the means which is adopted in one-word marketing in Guizhou Mobile business supporting system. All these steps will end to form a closed loop flow. For business sector’s global perspective, it is easier to strengthen the control of business recommendation, and it performs an active promotional function on system establishment.
