With the increase of the span of suspension bridge, the weight of the main cable increases, and the safety margin becomes smaller. Thus high accuracy is necessary for the construction control analysis of suspension bridges. The traditional finite element software cannot meet the accuracy requirement because of temperature, cable saddle and other factors, which influence the construction control. Based on the modified segmental catenary method, this paper has come up with a fine analysis method for the construction control of suspension bridges. And a software program called ZambisSC has been developed using object-oriented programming language combined with a number of the latest software development technologies. Compared with the monitoring results of Nancha suspension bridge in Guangzhou, China, it shows that ZambisSC can predict the main cable shape with high accuracy.

With the development and popularization of distance education, there was a growing recognition of this kind of education, students graduated from distance education were also more and more, which brought a greater difficulty to the center of distance higher education to manage student status. To solve the problem and respond to the education department's demand for informatization of education management, this paper did detailed research on the business processes of student status management, based on the MVC pattern and using workflow to design software for managing the students of distance higher education efficiently through prototype development methodology.

Safety signs can alert the staff to dangerous situation of the workplace or the surrounding environment and guide people to take reasonable actions so as to avoid accidents and mitigate the consequences of accidents. But unreasonable and noncompliant problems exist in the safety signs at the mine entrances. So four kinds of prohibition signs and four kinds of instruction signs that meet the standard requirements at the mine entrances are determined and that one kind of prohibition signs, three kinds of warning signs and one kind of instruction signs can be placed at the mine entrances are explained. At last the two kinds of layout design of safety signs are got and make it sure that the safety signs should be set at the same side of the mine entrances which serve as a reference for practical application.
Design Intelligent Service for Elderly People Using Living Lab Approach
Authors: Wang Ai Feng , Xing Xin Zhu
Published: March 2014

The quantity of elderly people are growing very rapidly, so the services for elderly people based on intelligent and smart-tech must be created to replace the traditional services for the shortage of resource. The importance of involving users in the innovation process has recognized by academia for a long time, Living Lab is a user-centric open innovation approach for fostering everyday life innovation in real life contexts. This paper propose a Living Lab methodology framework of service design for the elderly people, which emphasis user co-creator, user co-test, real life context construct by information and communications technology (ICT). The experiment results shows that involving users, real textual constructing by ICT and collaboration are benefit to promote innovation performance.
New Product Market Success for Bio-Tech Industry
Authors: Yu Chao
Published: March 2014

The role of organizational integration as an antecedent of new product performance has been extensively documented in the literature. A leading corporation must either develop new successful products to sustain its business competence or keep growing in global markets. Organizational integration has attracted ever-increasing interest because of the publication of seminal works and is a strategically valuable resource for successful new product development (NPD). This article focuses on NPD projects in the Taiwanese bio-tech industry. In particular, this study examines the mediate relationship between Organizational integration and new product market success through innovation capability. We propose our research model and then test it by applying structural equation modeling based on the partial least squares (PLS) methodology. The results show that organizational integration not only can achieve new product market success directly but can also increase new product market success through innovation capability.
Development Prospect of Requirements Engineering for C4ISR System

With the construction of C4ISR system was changing from technology-dominated traditionally to requirements-dominated, C4ISR system requirements analysis has already developed into requirements engineering. The conceptual framework and connotation of C4ISR system requirements engineering was introduced, as well as the procedure and methods. Finally, the status of domestic and overseas and future development trend for C4ISR system requirements engineering were analyzed, which will provide guideline for the research of C4ISR system requirements engineering.

Culture is an important factor for sustainable development of the enterprise, paid wide attention by the academic and corporate, at the same time, there are also many for enterprise culture research, which is mainly aimed at a particular analysis of the enterprise culture construction. With the development of society and the development, the social reform and innovation are going on unceasingly, Enterprise culture as enterprise adapt to the society and the demand of people also need unceasingly innovation and development, and cultural innovation and the cultural development is complementary relationship. Namely, cultural innovation is the foundation of the development of culture and cultural innovation promotes the cultural development, and cultural development and cultural innovation, make the cycle is progress. This paper is mainly based on cultural development and cultural innovation mechanism analysis, from mechanical angles of the culture construction and cultural innovation development of the coupling model, and through empirical analysis more strongly proves its of the coupling relationship between each other, to lead the enterprise cultural innovation and development.

Published: March 2014

Consumption growth trend of China energy is obvious, and the situation of energy shortage is serious. How to effectively use low energy to optimize the energy structure is one of the important issues in current research field of high efficiency and energy saving. In this paper, the fan is machinery by rotating shaft driven flow with a plurality of blades. From the overall situation, we analyze the fan wing structure characteristics. According to the fan aerodynamic performance and the k-ε model for numerical simulation, we proposed an improved GAMBIT simulation model and analyzed the simulation values for-360 degrees fixed angle of attack and different angles of attack. Finally we get the performance of the fan effect with different angles of attack, and it provides technical and theoretical support for the practice of the area in a certain extent.
The Discussion of Condition-Based Maintenance on Mine Cable
Authors: Di Chang Xin , Fu Zhou Xing
Published: March 2014

Cable condition-based maintenance is a high pertinence maintenance mode, with a good time effectiveness and economic comparing with planned maintenance. Three steps are needed in the procedure of practicing condition-based maintenance on coal mine, which are choosing state parameters, on-line monitoring, and state diagnosis. Having an advantage and disadvantage analysis on common on-line monitoring methods, the methods are corresponding to different state parameters. Combining with the actual condition of mine, present that the additional low frequent current method is easy to perform, meanwhile, the method is both fit for MVV, MYJV cable and MYP cable. Separately introduce two kinds of on-line diagnosis methods, one is based on the decision tree, and the other is base on fuzzy grey theory. The former adopt minimum entropy to choose testing feature, furthermore generate sub trees, the latter choose weight coefficient which according to the professors experiences to form cable diagnosis model. State diagnosis is the core in cable state maintenance, so how to establish an intact, scientific diagnosis model is the key.
