Abstract: Anti trailing of ATM system use the digital double differential move probe with infrared ray and microwave detection technology.These system includes digital processing software. The core is microcontroller of AT89C51 to control the pyroelectric infrared module , microwave emission detection module, infrared control module, voice chip modules and LED warning display by the process of burning into. The signal coming from each module is processed by Micro Control Unit to complete the the ATM around environment monitoring of customer to prevent the trailing events.

Abstract: The author, in this text, introduces the methods of the vibratory mixing, and gives the comparison and evaluation of the existent vibratory mixing methods. And this paper presents an improved twice vibratory mixing programs, such as the use of chaotic vibration exciter in the concrete preparation.

Abstract: This paper discusses a new algorithm solving zero-one integer linear programming models. Based on the analysis of different commonly used algorithms, we put forward a new algorithm named cards-flipping algorithm which demonstrate reliability and accuracy equivalent to enumeration methods. The correctness and practicability of the method are verified with mathematical proofs and a great deal of examples.

Abstract: Built on the slope and slope in buildings, in order to avoid a lot of digging embankment. According to the slope of potential changes, pile foundation is general unequal height. Design of such buildings in superstructure and foundation when considered separately, is to meet under normal load bearing capacity and deformation of coordination requirements. Due to the Bank's Foundation often under the influence of water level fluctuations, resulting in uneven settlement of pile foundation. Uneven settlement of foundation will inevitably lead to additional stress redistributes and superstructure of secondary internal force increases. Degree of influence on the structure of settlement of single pile has been building on the slope considering effects of uneven settlement of pile on the structure studies. This article focuses on studying two piles at the same time on the effect of settlement on the structure. For ease of study, this article to a shore in 8 layers of pile foundation in the framework, for example, using finite element analysis software ANSYS to different parts of the effect of settlement on the structure of two piles. Analysis shows that the class when the design of building structures, should fully take into account the underlying effect of settlement on the coordination of structural deformation, thus making the design more reasonable security.

Abstract: This paper presents an approach for modification a FEM simulation of electromagnetic tube compression process which has been presented by Mamalis. Electromagnetic free compression of a tube inside a coil has been simulated by using elements with coupled DOFs of electrical and magnetic potentials and displacement components. Mamalis's simulation results show a degree of disagreement with experimental results. In the present work, the coil has been modeled as separate parallel rings and a new correction factor has been determined for the current load applied on the coil. Comparison between simulation and experimental results shows a good agreement at the middle of workpiece with a reasonable error at workpiece ends.

Abstract: Veichle route problem with multi time windows is ani mportant issue in the manufacture and combinanl optimal problem, and has wide uses in the real life. Upto the problem in the real life, this paper build the mathmatic model, and analysis the complexity of the model. A heuristic algorithm is proposed based on the model, examples and test data is descripted to prove the vality and effective of the algorithm.

Abstract: The characteristics of switches have great influence on the performance of power tools. A test platform was designed and developed to test the performance of variable speed control switches in power tools, in which 3 kinds of modes can be conducted, i.e., life cycle test, lock rotor test and current step test. The test results showed that the platform was feasible, and very helpful for understanding and furthermore improving the characteristics of switches during different working situations.

Abstract: The paper studies on adjustment behavior of asset-liability ratio of manufacturing listed companies in China from a dynamic perspective. Based on the panel data from 2001 to 2008, this paper conducts system GMM methods to estimate. Results show that asset liquidity, non-debt tax shield, growth and net profit are negatively correlated with asset-liability ratio of China’s manufacturing listed companies, company size and asset structure are positively correlated with the asset-liability ratio, macroeconomic situation also has a significant impact on the asset-liability ratio; Companies can only make partial adjustment after deviating from optimal asset-liability ratio level because of the adjustment costs, the adjustment speed is about 0.345，the corresponding adjustment half-period is 2.01 years, the adjustment costs of asset-liability ratio of manufacturing listed companies in China are higher than that in the developed countries.

Abstract: Analysis the shortage of ultrasonic stress measurement based on Lcr wave in low spatial resolution. Point out it is inapplicable in measuring gradient stress field like welding residual stress field. In this paper, propagation differential method is proposed to solve the low spatial resolution problem on Lcr wave stress measurement, and its theory is introduced. This method can raise the spatial resolution from tens of millimeter to a several millimeter level with out decline the stress resolution. A welding residual stress field of 7N01 aluminum alloy butted joint plate is measured by this method, and its result is compared with hole drilling method. Source of errors is discussed. It is seen that propagation differential method is applicable in welding residual stress measurement.

Abstract: Forest fire fighting is very complex, the simulation using linear method is impossible. This paper proposed an Agent-based model for forest firefighting, designed the properties and behaviors of Fire Agent, Fighter Agent, and Commander Agent, simulated the fire spread and firefighting in forest by the three kinds of Agent’s actions, evolutions, and interactions; Developed the simulation software on Repast, which is composed of fire context, Agents, display, statistics and analysis etc; Simulated fighting with different number of Fighter Agent. The simulation’s statistics and analysis of Agents support both theory and practice for forest firefighting.
