Abstract: The paper defines the connotation and technology of business intelligence, discusses its concrete applications in supply chain management and studies the rules that the enterprises should follow while using business intelligence software. Through integrating the Business Intelligence with supply chain management, these problems can be solved effectively.

Abstract: A structure form is used by one vice-steering system software design for learner-driven vehicle, which combines software polling and interruption with subroutine call, namely a form of main program polling and interrupt service subroutine. Among them, main program mainly realizes the system initialization. Interrupt service subroutine is mainly used to sampling vehicle speed and the engine speed, etc.

Abstract: The weight control agency of crawler crane machine may be in the problem of inadequate strength in engineering applications. It will be analyzed and improved design by finite element. The bracket and frame are respectively calculated by static, established the finite element model, imposed loads, solved the result and sum up the stress distribution disciplinarian. The improved agencies are re-analyzed by the ANSYS. After re-analyzed, the intension of the weight control agency meets the strength requirement.

Abstract: The rapid development of supply chain will bring new opportunities for the convergence of corporate resources and upgrade of competitive power. Supply chain enterprises are encountering challenge of enhancing the stability. This article analyzes the factors to strengthen the supply chain management in term of node enterprises’ internal factors, the cooperation between node enterprises as well as social environment where the supply chain resides. To make enterprises to concern the information integration and e-commerce infrastructure construction, this article also proposes enacting the corresponding laws and agreements to reinforce the stability of supply chain.

Abstract: Under the assumption of stock price and interest rate obeying the stochastic differential equation driven by fractional Brownian motion, we establish the mathematical model for the financial market in fractional Brownian motion setting. Using the risk hedge technique, fractional stochastic analysis and PDE method, we obtain the general pricing formula for the European option with fractional stochastic interest rate. By choosing suitable Hurst index, we can calibrate the pricing model, so that the price can be used as the actual price of option and control the risk management

Abstract: RTC device driver on the PXA270 platform and Linux 2.6.31 kernel is designed in this paper. To design credible drivers, first, I2C bus and I2C driver framework are introduced. Then, all approach to the design of RTC driver based on ISL1208 is analyzed. And finally, RTC driver based on I2C is implemented and tested. This paper can provide some reference to RTC driver development on embedded systems.

Abstract: The purposes of this article is to develop a cultural approach in higher education studies. It will be argued that the cultural approach is rooted mainly in two different intellectual starting points to analyze academic communities as cultural entities: studies of disciplinary cultures and institutional cultures. Notions of disciplines as cultural entities have been developed in Europe in relation to the “two cultures” topic and to issues developed in the sociology of knowledge. The institutional studies tradition is, in turn, rooted in the American intellectual tradition, where cultural concerns emerge from institutional level phenomena whether they concern students, faculty or higher education institutions. The article discusses the pros and cons of these traditions in order to find new avenues for future research. It will be argued that academic identity provides a seminal perspective for cultural studies in higher education.

Abstract: In order to investigate the heat transfer of confined impinging jet with tiny size round nozzle, a bakelite laminate was used as the heat transfer surface of simulated chip. The thermocouples were mounted symmetrically along the diagonal of the laminate to measure the temperature distribution of the surface. The parameters such as Reynolds number (Re) and ratio of height-to-diameter were changed to investigate the radial distribution of Nu and the characteristics of heat transfer in stagnant section. The results show that hear transfer coefficient at stagnation point is maximal. It is decreased with the increases of the radial jet distance, but increased with Re and impinging height. Moreover, the effect of single-nozzle type is stronger than that of multi-nozzle type in the cases of same air flow. These studies will give a way for the application of air jet impingement in the electronics chip cooling.

Abstract: An opportunistic Network is a network consisting exclusively of users’ mobile devices, with mobility being one of its essential features. Under the circumstances that a path may never exist between the two sides of communication, an opportunistic network exploits node mobility to realize delayed data delivery by capturing the opportunities of node meeting to relay messages. Designing efficient data forwarding strategies is one of the most challenging tasks in opportunistic network research, while currently the validation of any protocol for data forwarding almost absolutely relies on simulations of which node mobility models are one of the fundamental components. In this paper, we suggest a purpose-driven user mobility model for opportunistic networks which, to our best knowledge, is the first work considering the factor of purposes behind users’ movement. On the basis of location functionalization, our model can gain a better approximation of human movement patterns.
