Abstract: Fingerprint recognition has wide application prospect in all fields which contain identity authentication. Construction of accurate and reliable，safe and Practical automatic fingerprint identification system(AFIS) has become researc hotspot. Although theoretical research and application developmen of AFIS have got a significant Progress，accuracy of the algorithm and proeessing speeds till need to be improved. In this paper, fingerprint image preprocessing algorithms，fingerprint singular Points and minutiae extraction algorithm and fingerprint matching algorithm are analyzed and discussed in detail.

Abstract: The consistency of the meaning of data in data warehouse is a key factor that affects the applications based on the data warehouse. In this paper, a system of cleaning and quality control of data in investment research system was built after investigating the estimation system, TA and other business systems of fund management company and analyzing the requirement of users. The system consists of an ETL program, and other products such as oracle, oracle stored procedures. This design approach can meet business requirements, ensure system scalability, simplify the complexity of the development of ETL program and improve the maintainability of the system. The method used in this paper has a high reference value for design and development of application systems that had the same characteristics.

Abstract: This article, aiming at the problem of simulating a RIA (radioimmunoassay analysis) curve by function, analyzes the difference among four common fitting methods used to solve it. The methods include Log-Logit transform method, 3/2-time equation method, Spline function method and four-parameter Logistic curve method. We Make comparisons of different fitting methods by using FM-200 series gamma immune counter test a same set of standard sample and get a conclusion that four-parameter Logistic fitting method is the ideal one.

Abstract: An important research of information retrieval technology is how to express the intention of users accurately and make a sensible judgment on the semantic similarity between conceptual entities. A scheme is presented to calculate the semantic similarity, which takes multi-inheritance of entities and property values into consideration , and then optimizes the computing process based on the tree structure of inheritance relationship. When the instance multiple inheritances are relatively complex, the accuracy rate is more pronounced than existing methods. The experimental results show that the scheme proposed in this paper can calculate semantic similarity more accurately even in ontology-based knowledge base.

Abstract: Cloud computing as a new model of information technology, which is emerging as computing concept that promises provision of computational resources on demand and abstraction of technical details from the clients, in the IT sector has attracted more and more attention. Nowadays, with the popularity of smart mobile phones, the increasing functions of smart mobile phone could not meet the requirements of users. To solve this problem, cloud computing is applied in smart mobile phone. Finally, the detail of the current station of the application of cloud computing in smart mobile phone and some introductions of how to develop the application will be introduced.

Abstract: UML, as an international standard, is not suitable for static modeling of the program procedure. While Procedure Blueprint is a visual process modeling language and is suitable for modeling the procedure, which can supplement the UML deficiencies during the process of modeling the program static structure. In this paper, taking XMI as a common data structure and a data exchange bridge, proposed the general transformation idea, the transformation rules and the transformation algorithm from activity diagram to the procedure blueprint. This has laid the foundations for achieving the model transformation at last.

Abstract: With the rapid increase of mobile phone, people’s requirements of entertainment have become higher and higher, the demand for the game is the most prominent. Game development based on Symbian platform has higher efficient implementation and powerful function. There is the problem of screen flickering for most games written by beginners. By introducing the problems that encountered in the development of Sudoku game, showing new methods that how to use double buffering and direct screen access technology to solve the problem of screen flashes that exist in the game interface, as a result the fluency of the game’s interface has been greatly improved.

Abstract: Aiming at regulating the toll evasion behaviors in highway weight charges and reducing charge disputes caused by jumping, this article studied the algorithm that tracks vehicle beating when it is passing the scale. Based on license plate location, vehicle movement could be characterized by tracking the plate centroid using Lucas-Kanade optical flow algorithm. The optical flow vector of the centroid was calculated frame by frame, which could be used for drawing trajectory of centroid coordinates, and calculating beating parameters. In order to expand the detection range and adaptability of the algorithm, through calculating optical flow hierarchically combined with Gaussian pyramid, then tracking centroid from high lever to low in the image pyramid, it could achieve the capture of the vehicle' fast moving. Through experiments, trajectory reflected vehicle beating information well, which provides a strong evidence means for levy problem of the highway weight charges.

Abstract: This paper proposed a new Ad Hoc dynamic routing algorithm, which based on ant-colony algorithm in order to reasonably extend the dynamic allocation of network traffic and network lifetime. The Algorithm choose path according transmission latency, path of the energy rate, congestion rate, dynamic rate. The Algorithm update the routing table by dynamic collection of path information after path established. The analyse shows that algorithm increases the network throughput, reduces the average end-to-end packet transmission latency, and extends the network lifetime, achieves an improving performance.

Abstract: MATLAB is a powerful tool for data processing. This paper focused on how to enhance the efficiency of scientific computation in seismic data processing by improving the traditional MATLAB programming code. Some examples were presented to demonstrate the advantage of vector addressing over the traditional scalar addressing. Vector addressing programming can simplify the code significantly, and can it also improve the compiling efficiency and executing efficiency of the code. The other examples were given to illustrate the use of the colon and some special values that can improve the MATLAB programming efficiency. Some issues in this paper can also serve as guidelines for professionals in other disciplines.
