China provides an excellent empirical case study on the information transmitting efficiency in the capital market. Our paper extend the existing investigation based on much more new data and test the efficiency of information transmitting with Individual, Sub-sampling and Wild bootstrap Variance Ratio method. The empirical results show that gold prices reflect all the past information efficiently and no one can get abnormal return continuously. The China gold spot price followed Random Walk and the gold spot market is a weak-form efficiency market.

When people calculate water influx using the gas reservoir engineering method, they usually utilize three methods of van Everdingen-Hurst, Carter-Tracy and Fetkovich. In this paper, we analyze and compare the three traditional calculation of water influx. Then after a detailed analysis of Fetkovich method, water influx calculation software is developed using vb.net based on Fetkovich method. Finally, example is calculated using the software developed.

This paper is based on the concepts and features of the inventory of supply chain management issues as to discuss how the stakeholders gain a win-win in the formation of the supply chain. On the way of a win-win, the inventory management mainly faces these two problems: the Bullwhip Effect and the Stock Transfer. And in order to solve these problem, the stakeholders should cooperate with each other, should improve their technology and also they should simple the process.

Social networks have been critical areas of social science research. Researchers have focused mainly on how to make use of social networks, while giving little attention to social networks' cost. To address this drawback, we adopt a new perspective of cost analysis to discuss social networks. A cost model is proposed in this paper, which demonstrates the origins of networks cost coupled with cost form and three phases of cost forming.

A new approach, XenPR, was designed to protect and recover processes in a kernel crash. XenPR exploits the isolation feature in Xen to maintain a minor kernel image outside of the main OS kernel. When a crash happened to main kernel, the minor kernel will take over the business from it, save the process context and reboot the operating system. Then the applications can continue the execution seamlessly or only with moderate interruption. Our evaluation shows XenPR reduces the computing loss in system failure and improves the reliability and availability of programs.

This paper examined cost of capital reactions to management's evaluations of internal control and audit opinions on reports of internal control which based on samples of 2008 Chinese Shanghai Stock market, the results have shown that, those companies who disclosed positive internal control or clean audit opinions on reports of internal control will bear lower cost of capital, compared with the companies those who have shown negative actions on internal control disclosing or negative audit opinions on internal control reports after controlling for other independent variables. Overall, the result of our cross-sectional test is consistent with good internal control will be valued by capital market.

It is difficult to design mathematic models for the problems of assembly line queuing in the workshop, and simulation is usually made in the computer. But it requires that the researchers have high level of computer proficiency to build up a simulation model with a computer language. Taking Excel as a tool, we have established a simulation model for the problems of two-stage assembly line queuing. With this model, we can not only easily examine the production efficiency of this assembly line, but also examine whether enlarging the space between the two workstations could impose some influences upon the productivity of assembly lines and the waiting time.
