Published: December 2014

The purpose of designing recommender systems is to help individual users find relevant information. However, many recommender systems have been facing the challenges of finding niche objects, which users may like but difficult to find due to the lack of sufficient data. In this paper, we propose a recommendation algorithm which takes a niche object as input and outputs a list of users who may be interested it. By this approach, every niche object can be recommended at least one time. Further analysis indicates that those niche objects are usually collected by active users and the owners who are very similar to each other. Therefore, this work has outlined the significant relevance with the challenge, the Long Tail problem, and provided a different perspective to solve it in the field of information filtering.

We have designed and implemented a location service framework in the private cloud storage system based on logical disk. Location service is very important in the private cloud storage system and many people are eager to improve the performance of the location service. But the algorithm for location service is fixed so that we can’t change the algorithm even we find a better one. In order to adopt the new algorithm, we need to redesign the location service system. Therefore, we design and implement a location service framework to solve the problem. The location service framework makes development more fast and flexible. The developers and designers can concentrate on algorithm and need not to worry about redesigning the location service system. What’s more, the location service framework can provide the fundamental features of the location service. At last, we prove the effectiveness through simulation testing.

Authors: Du Chuan Bao , Quan Hou De , Cui Pei Zhang
Published: December 2014

The Dual-Channel Network proposed in our previous work can improve the code resource utilization efficiency. Carrier Sense Random Packet (CSRP) CDMA and Partitioned Slot Reservation Packet (PSRP) CDMA were proposed for enhancing the control channel interference resistance of Dual-Channel Networks. In this paper, we investigate CSRP-CDMA and PSRP-CDMA, and derive the performance analytic models by taking into account both intra-cluster MAI and inter-cluster MAI. The models provide the expressions of packet transmission probability and normalized network throughput. Furthermore, the probability of packet successful transmission and the throughput performance are compared between the two protocols. Finally, we analyse the influence on the network performance with spread spectrum gains and network scale. The numerical results show that, normalized network throughput of PSRP-CDMA outperforms CSRP-CDMA by 20% to improving the code resource utilization efficiency of control channel of Dual-Channel Networks.

Published: December 2014

Researches on how to solve visual perception concept in UI design with the help of visual thinking are a kind of creation to the mode of UI design which make full use of the theory of visual thinking as well as a conclusion to the combination of the theory of visual thinking and digital medium. Not only did the essay make conclusion and summarization to the application of visual thinking in the field of UI design, at home and overseas. Meanwhile the author also made her attempt to analyze and probe into the use of visual thinking in 3D UI design in light of her own practical experiences. The essay emphasized the important role and advantages that visual thinking take in the study of UI design, which will open a new window for the further study and application, as well as provide a practical reference accordingly.
Tourism Information Search System Based on Android Mobile Phone
Authors: Hu Yan
Published: December 2014

In this paper, a design and an implementation on an intelligent guide system based on Android platform is proposed. The hardware of system is based on ARM platform, and the schematics of its main modules such as power, SDRAM are given. Then Android operation system is transplanted on the ARM platform. On this basis, the application software is developed using Eclipse and Android SDK, and it is consisted of three modules: multimedia application, web maps and recording. The module of multimedia application includes audio, picture and video. Web maps can display Google Maps on the device and achieve positioning. The record module has implemented the several normal operation on a record, such as creating, modifying and displaying.

Design and Realization of Algorithm Visualization Teaching Presentation System on Computer Graphics
Authors: Wang Zu Wei
Published: December 2014

Based on the study of abroad foundation on visual theory, we conduct depth discussion of the current introduction of visual teaching meaning. For the current computer graphics course content, we determine a visual teaching content and objectives, carry out the study and practice of computer graphics algorithm visualization teaching. This paper uses VB 6.0 visual programming tool to generate the basic primitives, polygon filling, cut a straight line segment, curve generation and visualization of fractal algorithm design and realization. Through analysis, this paper hold that use of visual teaching has a positive effect and influence for professors to change the way teachers help students understand computer graphics algorithm. In the process of teaching, students improve the understanding, exploration, discovery and creativity through observation, conjecture and verify.
Design Practice Guidance Modes Based on Network Technology
Authors: Yang Xiao Feng
Published: December 2014

Combining computer network and students feature, with analysis the exited features of students’ practice guidance ,mainly as real-time interaction for core, the purpose of which is to design educational practice guidance modes based on BLOG, and BBS and QQ, the article takes students of year 2007 in Shangluo university for object as case to explore BBS –based interactive discussion mode, reaching the purpose of settlement of difficult offsite management ,insufficient practice guidance and incomplete exchange between teachers and students, etc. thereby, archieve an effective guidance for students’ practice.
Application of Web-Assisted Instruction System to Physical
Authors: Yuan Shao Hui , Ma Wei
Published: December 2014

The development of computer and online education has promoted the development of physical education. Web-assisted Instruction system can improve the current teaching environment and students’ learning efficiency. Based on human-oriented concept, it is able to facilitate students’ selective learning and help them establish the idea of “lifelong sports”. But the popularization and development of WAI still need to be further improved.
Construction and Application of Interactive Network Learning Platform in Information Age
Authors: Ning Dian Xia
Published: December 2014

With the development of Internet technology, network learning has become an important form of learning in today's society. Network learning is inseparable from the network, and interaction is an important part of online learning, which has a very important position and role in the development and application of network learning platform. In this paper, network learning environment lacks substance interaction and network learning community ignores teaching based on literature research and network investigation of network learning environment. And this article proposes the method that contains substance navigation strategy based on question, establishment situation animation and giving the positive appraisal which can solve the problem that network learning environment lacks substance interaction, proposes the method that contains controlling jurisdiction of debarkation, establishing hierarchical system and Inviting the expert to seat guests which can solve the problem that network learning community ignores teaching.
Research on the Application of the BP Neural Network
Authors: Yu Cao
Published: December 2014

The paper constructs an evaluation model for practical teaching quality based on Back Propagation (BP) neural network. It makes the indicators of evaluating practical teaching quality as input data, while practical teaching quality as output results. The empirical conclusion obtained from the use of Excel is that BP neural network is suitable for practical teaching quality evaluation and also makes a better analogy to the experts’ evaluation process. The results are satisfactory with wide application.
