To ensure monitoring quality of wireless sensor networks (WSNs)，sensors were usually deployed densely．If these nodes worked synchronously，they may cause many serious channel conflicts，and generate a quantity of data，which result in a large energy consumption．Hence，it was an energy efficient way to active nodes alternately．It was researched in this paper and a prediction-based scheduling algorithm called PSGM was proposed．In PSGM，cluster heads managed nodes and scheduled the sleeping of nodes with low energy．Then the data of the sleeping nodes would be got by cluster heads with some prediction algorithm．Simulation results showed that PSGM prolonged the lifespan of the network and assured the accuracy of data．

The ISA bus is industrial standard bus architecture，which survives a long time in the industrial area，is the first system-level bus．USB bus is more and more popular because of the convenient features that make its application extensively. USB interface equipments become more and more in the electronic market，USB bus replaces the traditional old-fashioned interface will become a trend．The paper introduces the USB bus and the ISA bus；then mainly introduces the design principle， hardware design and software design of the transfer cards based on CH375 chip；finally introduces the applications of adapter card in engineering．

In order to draw three-dimensional objects on computer，using a resolution method to analyze the perspective projection transformation technology，design a perspective projection transformation software algorithm．This algorithm performs projecting real world three-dimensional objects on computer as well as rotating and scaling the objects by changing the relevant parameters．The results show that this application is very useful for 3D animation software development．

The design and the application of the digital filter is one of the core content of Digital Signal Processing．In order to simplify the process of filter designing，and to adjust the parameters conveniently， methods by making using of the FDATool and Simulink toolbox in MATLAB to achieve the design of the digital filter and simulation quickly and efficiently are put forward．

To detect and recorgnize the abnormal activity under intelligent supervisory system，a simple but efficient action recognition alogrithm using sequence matching is proposed．For each image sequence，an improved background substraction algorithm is first used to segment the action sequence．Then eigenspace transformation based on Fourier descriptors are used to extract action feature in training stage．Extensive experimental results on common databases demonstrate the proposed algorithm has an encouraging recognition performation．

The system of Robocup robot soccer game of medium-sized groups has characteristics of highly dynamic changes in the environment and highly confrontational．A new task decomposition method for soccer robot system is proposed in this paper based on the location of each robot of opposed team．The paper gives the introduction of the radiation zone to describe the range and inclination of the robot at a time instead of the traditional approach which regard one robot as a point，it also gives a method to realize a dynamic segmentation of the playfield based on the distribution and the sparse level of robots in the opposite team，which can make the task decomposition has features of flexibility and advancement．Simulation results show that the proposed method is simple and practical，robust resistance

The article introduces VR technology into the progress of a construction project. The technology can realistically simulate the construction on the computer before the beginning of the project so that we can evaluate the progress of the prospective project，finding the possible problem in the progress and avoiding similar problem during the construction．

In the modern real-time monitoring systems and industrial automation systems， many systems communicate with the serial device to control the terminal equipment．How can the development of efficient and fast serial communication program is particularly import．In this paper，taking a practical control system as the background，brief introduction of serial communication is given，the SerialPort class is used to realize the process of serial communications．Finally，with the practical application，it is demonstrated that SerialPort class can easily and quickly realize serial communication．

This paper described Analysis、Designing and Realization of the System of Bank Accounts Payable．This sytem based on the MVC pattern，and using OFBiz frame ensure the system efficient and tability，at the same time a substantial increase in the development efficiency of the project．This system also use xml、css、javascript、java technology．Deposit、Withdrawal and Interest function of Core banking sytems has realized．

Software development cost estimation is a critical step in project development，which directly affects decision-making and the management of tasks arrangement．There are many different ways of estimation．Each way has its advantages and disadvantages．How to make good use of relevant technology for more accurate prediction is becoming a major topic in this article．We discuss how to predict the main characteristics of objects and select the appropriate parameters to construct the regression model，further improving the forecast accuracy．
