Abstract: The algorithm is a key part of the online course registration system. It plays a vital role on the online course registration system to ensure most of issues like fairness, network bottleneck, multi-registration and multi-dropping be solved well. By supporting the registration way of multi-level, multi-category, and multi-willingness, introducing the willingness of students into the calculation of course priority and letting the willingness of students affect the selective probability, it meets the registration requirement maximally and solves the issues well including fake registration number and random registration. This article will introduce the design and implementation of the algorithm.

Abstract: Service providers provide virtualized IT resources by using Internet technologies in their services. Users use the provided IT resources as much as they want and pay the corresponding fee. In such cloud computing environments, issues of malicious codes, hacking and leak of confidential information are the biggest concerns of the people involved. In this paper, we study the virtualization security management, which is important for the proper management of collection of virtualization resources information and security events, monitoring and analysis of cloud security situations, and cloud security policies. Specifically, we propose the structuring of the virtualization security management system and the management method to reduce the complexity of administering the virtual machines installed in the cloud data centers caused by the inherent properties of virtual machines characterized by dynamic changes in the form of image files. Therefore, we studied the tracing method for history of infected virtual machines following an analysis of the VM lifecycle status and VM running states.

Abstract: In order to meet the needs of conveniently, fast and accurately calculating the balance coefficient in lift supervisory inspection, this paper proposed a novel method based on android smartphone terminal. First, the boundary value problem was discovered in the balance coefficient curve fitting, and the fusion algorithm of curve fitting and interpolation is proposed. Secondly, the coefficient calculation software was developed based on android smartphone after its function was designed. The experiments show that it can meet the requirements of test and the efficiency is also greatly improved.

Abstract: According to the advantages of cloud computing which is a new technology and the developing state of the information management of oil enterprise, this paper builds a information management mode for oil enterprise based on cloud computing, in order to solve many certain problems in the recent information mode. Analyses the different business needs in the up and down stream in Oil Company, and then build an enterprise hybrid cloud management model. Under this mode, the information management of this company can realize lower IT operating costs, lower energy consumption and higher efficiency, and also take balance between efficiency and data safety. This kind of mode not only fits into the developing need for Oil Company, but also the need for green IT age.

Abstract: It takes too much time for the software system of electron beam lithography to display files with large amount of graphic data, which affects the efficiency of electron beam lithography. In this paper, a graphic displaying algorithm is proposed and experimented. The result shows that the displaying algorithm not only guarantees the precision of the graphic data, but also displays files with large amount of graphic data fast, improving the efficiency effectively.

Abstract: Recently, GPU has been introduced as an important tool in general purpose programming due to its powerful computing capacity. In data de-duplication systems, GPU has been used to accelerate the chunking and hashing algorithms. However, the data transfer latency between the memories of CPU to GPU is one of the main challenges in GPU accelerated de-duplication. To alleviate this challenge, our solution strives to reduce the data transfer time between host and GPU memory on parallelized content-defined chunking and hashing algorithm. In our experiment, it has shown 15%~20% performance improvements over already accelerated baseline GPU implementation in data de-duplication.

Abstract: Based on CP-nets models, an approach of test case generation is proposed for BPEL processes, with which the semantic of BPEL concurrence is well dealt. Firstly, a web service composition which coded in BPEL language is expressed as CP-net models on which depth-first traversal works immediately, and result in sequence test paths obtained. After merging these sequence test paths into program executable units (PEU for short), constraint set of these units is solved and formed into test cases. Finally an application of the approach is illustrated with an example, which more efficiency shown with 7 test units less than 9 test path appear in reference available for same example.

Abstract: Website Design is an important part of Website Construction. The construction of excellent course website can play its roles though designing an excellent website, which can serve the teaching better. This paper presents our own ideas of personalized excellent course website construction and innovative design from the following aspects: The analysis of problems on current excellent course website construction, the requirements of personalized website construction and personalized website design.

Abstract: AOP(Aspect Oriented Programming) is a programming technology that makes the OOP (Object Oriented Programming) technology more complementary and perfect when being applied together with OOP technology. AOP provides ideal modularized structure for programming. At the moment, AOP has been supported and applied in two leading programming platforms: Java and .Net. Java provides perfect support to AOP, but .Net has not clearly provided the technique to support AOP. Meanwhile, Design Pattern has been widely used in programming. This study analyzes the theory of AOP technique and provides an implementation strategy for AOP based techniques on Proxy Pattern in .Net platform.
