Abstract: This paper elaborates the necessaries of using high-tech means to monitor and early-warn significant hazards, introduces the main contents for monitoring and warning technologies, discusses the organization structure for monitoring and early-warning significant hazards system, proposes corresponding accident emergency prevention plans.

Abstract: According to the current situation that banana pesudostem resources are rich in china while the utilization of stems and leaves is insufficient. the development situation of the banana pesudostem mechanization treatment are summarized. And this paper points out that the low level of banana pseudostem mechanization has become an important factor restricting the development of the banana industry in China after analysis. Combining the research status of pseudostem mechanization treatment, this paper discusses its development tendency and proposes several potential ways of mechanized treatment, providing a reference for improving the level of mechanization of the banana industry.

Abstract: Transplant quality and performance of rice transplanter depend on transplanting mechanism, common design and analysis methods was introduced based on high performance transplanting mechanism, and also introduced research status and shortages of various kinds of methods, and also put forward the develop direction of design and analysis method for transplanting mechanism, simultaneously provided a method reference to design and optimize the high performance transplanting mechanism.

Abstract: There are more and more overseas offshore oil project in china, along of external interdependent level in petroleum becomes upgrading year by year. Therefore, developing quick forecast method on overseas offshore reservoirs becomes very necessary. The method is divided into three steps: i the core data analysis results are used to calibrate the interpretation about logs of well, ii the well log interpreted results are used to mark seismic data, iii the abundant seismic data is used to forecast overseas offshore reservoir quickly. And rear end in this article, an overseas offshore reservoir is used to as an example to verify the applicability and reliability of the method.

Abstract: The right panel stamping forming is an important prerequisite for generating qualified parts, an important step before the panel forming simulation is to determine the reasonable forming of the stamping. Manually adjust parts in order to overcome rely on experience, the drawbacks to the stamping forming, the forming of the stamping punch and forming the contact area of the sheet as the goal of automatic determination control process. Objective function of the forming of the stamping for the variable contact area in the stamping forming of the feasible region, the use of heritage control processs to optimize the objective function of the contact area and, ultimately feasible within the contact area corresponding to the stamping forming, that is the best stamping forming. The measured results show that the forming of the stamping based on genetic control process, the automatic control process can fast and accurate to obtain the optimal forming of stamping.

Abstract: ETC has become an urgent need of social development. This paper first analyzed the current situation of highway ETC, then researched on RFID technology, established the city ETC system based on RFID, it greatly improves city vehicle management efficiency, prevents manual vulnerabilities, promotes the city automation construction.

Abstract: The hazard of chemical process equipment consists of two parts: the inherent hazard of process equipment and the hazard from domino effect among equipments. The inherent hazard of equipment depends on the properties of the substance present in the equipment and the specific process conditions. The domino effect is responsibility for many most destructive accidents in the chemical process industry. However, domino effect is either not considered at all or is done with much less rigour than is warranted. A method was proposed to evaluate the hazard of chemical process equipment. The inherent hazard and the hazard from domino effect were considered in the method. The procedure for the domino effect analysis among equipments was presented to evaluate the hazard from the domino effect. The method was implemented in a case study. The results show that it can be used to select the process equipment which should be intensive monitored.

Abstract: Suppose that the life of unit is distributed as two-parameter exponential distribution. The Bayesian estimation for cold standby series system is studied based on general Progressive type II censored samples. Under the different error loss, the Bayesian estimation of the unknown parameter and reliability function are derived where hyper-parameters are estimated by using Maximum likelihood method. At last, a numerical example is given by means of the Monte-Carlo simulation to illustrate the correctness and feasibility for the method proposed in this paper.

Abstract: In this paper, two synchronization schemes between two different chaotic systems are proposed. Chaos synchronization between unified chaotic system and Rossler system via active control and adaptive control are investigated. Different controllers are designed to synchronize the drive and response systems. Active control synchronization is used when system parameters are known; adaptive synchronization is employed when system parameters are unknown or uncertain. Simulation results show the effectiveness of the proposed schemes.

Abstract: The capability-oriented requirements elicitation is an emerging research topic of requirements engineering, especially for complex system such as the C4ISR system. One of the problems is that the capability requirements are usually articulated in natural languages and need to be formally specified to support enterprise architecture analysis. The paper proposes a framework for modeling the domain requirements of C4ISR capabilities and suggests an extended UML modeling technique. As the modeling framework accords with the standard DoD Architecture Framework, the proposed method may populate C4ISR architectural analysis.
