Abstract: This paper is mainly concerned about the theoretical argument from Software design, which is based on underwater acoustic remote-control communication system of low-power signal chips and the simulation study on its core algorithms and its implementation on hardware system. Each command needs 125ns to be executed, while the master frequency of this filter is 8MHz, so it cannot deal with the signal processing synchronously. This process can only start after all the code elements are stored, which takes 2 seconds. However, the filter is so economic in energy that this micro-power system is endowed with a broad prospect in remote-control application, where the demand for synchronicity is not high.

Abstract: Reviewing the historical context of theory and practice development on transportation after the New China’s founding, especially since it reformed and opened to the outside world, this paper presents development of frame diagram and refines ten substantive characteristics of modern integrated transportation system. Realizing the sustainable development of transportation are not only the focus of scholars and policymakers in the field of transportation, but also the practical meaning that meeting the demands of the rapid development of social economy.

Abstract: Quasi-static structure in each configuration and load conditions may be static stiffness or frequency of a special vibration mode can be optimized to meet the design requirements. Considering the size disparity in stiffness and load conditions, the unit strain energy density as the unit of sensitivity is proposed as the basis of cell properties to modify the sensitivity of the dimensionless mixing measure, and use the evolutionary algorithm with recovery function, calculation will be simple and implement easily in the large-scale finite element software, and can quickly reach optimal goals. Meanwhile, the proposed calculation eigenvalue sensitivity of unit and sensitivity synthesis method can also be taken into account static sensitivity and dynamic sensitivity to meet the dynamic performance requirements.

Abstract: The state-owned and state-holding industrial enterprises play an important role in the process of China's industrial and economic development. Since 1998, China's industrial economy successfully resisted the effect of economic crisis in Southeast Asia, and maintained a good momentum of development, but the development of regional industrial enterprises in China still exists certain fluctuation and unbalanced characteristics. In order to measure and analysis the overall situation of China's industrial enterprises, this paper presents an evaluation method for the economic benefit of industrial enterprise based on panel data. Comparing with the data in 2008, we measure and analyze the economic situation of the state-owned and state-holding industrial enterprises in China's 31 provinces from 1998 to 2008, and analyze the overall situation and future trends of China's industrial enterprises.

Abstract: Within the context of the different product types and marketing strategies involved in ecommerce transactions, this paper suggested that high-value and time-varying products (HVTVP) made up the core of the market. These products are characterized by high brand recognition, high market price, price decay over time, and stable physical properties. This paper analyzed the structure of the pre-sale period of HVTVP and described the pre-sale period by dividing it into distinct functions. Based on this analysis, it discussed the characteristics of the logistics distribution network during the pre-sale period and established a decentralized bi-level programming model for the logistics distribution network of HVTVP within this period. This model was solved using an interactive fuzzy algorithm, which was tested and verified through numerical analysis.

Abstract: On the current scale of the Internet, the single web crawler is unable to visit the entire web in an effective time-frame. So, we develop a distributed web crawler system to deal with it. In our distribution design, we mainly consider two facets of parallel. One is the multi-thread in the internal nodes; the other is distributed parallel among the nodes. We focus on the distribution and parallel between nodes. We address two issues of the distributed web crawler which include the crawl strategy and dynamic configuration. The results of experiment show that the hash function based on the web site achieves the goal of the distributed web crawler. At the same time, we pursue the load balance of the system, we also should reduce the communication and management spending as much as possible.

Abstract: Ecological administration is a mode that economic development and environmental resources are in harmony, as well as the relationship between enterprises and society develops sustainablely and harmoniously. This mode integrates the ecological ideas with the whole administration process of pre-inter-post production based on the theory of ecological economics, and establishes the chain of industrial ecology encompasses “producer, consumer and restorer”. Sichuan Tuopai Group reengineered the ecological structure of Liquor-making industrial system, and established the harmonious chain of industrial ecology in order to achieve the circulation utilization of materials and energy, thus has formed the harmonious and sustainable Liquor-making industrial system with low consumption and low pollution. It’s obviously the vibrant practice of ecological administration in China.

Abstract: This paper describes a method for software design and proposes a control strategy for data processing in temperature control system. According to the proposed method, a combined feed-forward plus PID control is proposed, with additional temperature sensors, the major load disturbance attached to the system is measured. The experimental results demonstrate that the temperature control strategy significantly improves the dynamic performance on the control process.

Abstract: The offshore region of Haizhou Bay is characterized by intense anthropogenic activities. And the study on comparative analysis of water quality status in this offshore region has attracted more and more attention of the researchers and decision-makers. In this paper, comparative analysis on water quality status of different samples in Haizhou Bay during May 10-21, 2007 was studied by principal component analysis method (PCAM). The water quality status in Haizhou Bay was compared and analyzed by using 13 samples, with DO, SS, Active Phosphate and Petroleum impact factors. Based on the PCAM analysis procedures, the comparative analysis results of water quality state in Haizhou Bay show that the spatial order from good to bad is determined as follows: JS03> JS01> JS04> JS07> JS02> JS09> JS05> JS06> JS13> JS10> JS12> JS08> JS11.

Abstract: In order to solution the problem of mining maximal frequent subgraph is very hard we proposed new algorithm Top-Down. The process of this algorithm is using decision tree to count support then firstly judge the biggest graph whether frequent and gradually reduce the graph which used to judge until can not mining maximal frequent subgraph, at the same time this algorithm is proposed a theorem and two principles these are improved the mining efficiency.
