Abstract: Facing the particularity of the current limitations and spatial clustering clustering methods, the objective function from concept clustering starting to GIS spatial data management and spatial analysis for technical support, explores the space between the sample direct access to the distance calculated distance and indirect reach up costs. K samples randomly selected as the cluster center, with space for the sample to reach the center of each cluster sample is divided according to the distance, the sum of the spatial clustering center of the sample to reach its cost objective function for clustering, introduction of genetic algorithm, a spatial clustering algorithm based on GIS. Finally, the algorithm is tested by examples.

Abstract: Analysis of a company in the customer management problems, and discusses the design goals of CRM system. Using the current mature J2EE technology, design and develop a CRM system, and the architecture and the function module of system are discussed in detail.

Abstract: In order to remotely manage and monitor the experimental devices in Neutral Beam Injection (NBI) system, an equipment management client software is developed as the human-machine interface between the server control layer and the field control layer. The client software based on network technologies communicates with main control server. NBI Equipment management client software developed in C/C++ language has been deployed to the distributed field control computers with the Windows operating system. Experimental results show that the program ensures equipment security and promotes the progress of the experimental operation smoothly.

Abstract: With development and progress of the network communication technology and computer technology , the office automation obtains the rapid development, in order to promote the development of automation level of college office workers. In view of correcting the students' homework heavy tasks for the current university teachers ,for resolving the heavy tasks of correcting the students' homework and improving efficiency, the paper adopts J2EE platform combine with JBPM workflow technology, design a three-tier system of the whole system and realize the whole system, develops with the function perfect, simple operation ,the contact surface friendly, the safe stable homework correction management system, so that the system has high operating efficiency, good extendibility and maintainability.

Abstract: In order to meet the request of high-speed data exchange in embedded systems, this paper details the high-speed SRIO (Serial RapidIO) interface protocol and the process of SRIO access timing between the local endpoint devices and the remote endpoint devices. And also we implement the design of the new high-performance RapidIO interconnection between DSP and FPGA. Through the performance testing of SRIO data transmission system, experimental results show that the design can stably transfer data at high speed between processors.

Abstract: Design an image feature information recognizer using the maximum entropy principle, extract feature information from image file. Set the learning process of the characteristic database in finite source identification of threshold, including the source feature information database learning,and the identification evaluation to dynamically set a threshold for the feature information classification.

Abstract: The core objective of Big Data technology is trying to dig out valuable information from massing huge variety of data structures. In order to achieve these goals, Big Data technology must be combined with machine learning. The uniqueness of Big Data has also brought unprecedented challenges to machine learning, in order to cope with these challenges machine learning should focus on the development of semi-supervised learning method, integrated learning with device integration and transfer learning method.

Abstract: Digital image processing is a technology that using computer to process images through a certain algorithm. It has been widely used in many areas of engineering and military. The system which is fit for the researching and teaching plays a very important role in the fields of scientific research and education. This paper discusses the development of image processing system and image processing technique in MATLAB. In practice, the operation of the system is convenient its interface is beautiful and its vision is very good.

Abstract: Near-field acoustic holography (NAH) is a powerful technique for identifying noise sources and visualizing acoustic field.The theory and algorithm of NAH techniques are introduced , and it is proved by experiment and simulation. The researches on near field acoustical holography (NAH) are reviewed，including the sound field separation technique and Patch NAH technique arisen in recent years.The difficulties in NAH and research on current situations are discussed , Finally,some engineering applications are introduced by detailed examples.

Abstract: In order to solve the problem of only have a few historical data that can be used in multivariate process monitoring, a new distribution-free multivariate control chart has been proposed. And in the control chart structure the control limits are determined on-line with the future observations and the historical data. Therefore, the proposed control chart has very important application in practice. However, the research doesn’t study the problem of the fault diagnosis after the control chart alarms. So we use LASSO-based diagnostic framework to identify when a detected shift has occurred and to isolate the shifted components.
