Abstract: Short-traffic flow forecasting is an important part of ITS, and its accuracy and real-time is directly related to the effect of traffic control and traffic induce. Gathering and analyzing the real-time data of urban road network ,short-time traffic flow forecasting could estimate the state of traffic flow for a few minutes in future and provide support to intelligent transportation control, so it is one of the important premise for ITS.

Abstract: The flagship firm in the supply chain integrates resources through SCM (Supply chain Management), optimizing the information flow，logistics and capital flow in the supply chain to obtain long-term competitive advantage and enable firm to enhance market response and competitive capacity. It has many abilities to get economy rent through implementation of SCM, flexible production capacity is one of those abilities. Based on the view of real options, this paper regarded this ability as a call option. Construct a model to analysis the value of flexible production capacity. Calculate the option value using Monte Carlo simulation，Matlab programming. Illustrate a numerical example and make a parameter sensitivity analysis.

Abstract: In this paper, we developed an infrared polarization imaging system. The system is composed of imaging lens, IR polarizing filter, medium wave IR detector, and image acquisition system. The design scheme of implementing target recognition with IR polarization imaging system was presented, and the IR Images with polarization information have been acquired by this system. On the basis of Stokes parameters and polarization IR images processing, the images of linear Stokes parameters (I, Q, U), the image of degree of linear polarization (P image) and the image of angle of polarization (X image) could been obtained. The image of PUX fusion image could be achieved by the pseudo color fusion. The results of actual experiment and quantitative analysis data confirm that the target in the processed images obtained from IR polarization imaging system is much clear than that in the original IR image.

Abstract: Given the uncertainty of parameters and the random nature of disturbance, a ship motion, is a complicated control problem. This paper has researched adaptive neural network systems and its application to ship’s motion control. In paper, Ship’s mathematical model is researched. Aimed at ship mathematical motion model, the model reference adaptive auto pilot is first designed based on the analysis of the model reference adaptive control theory. We used fuzzy logic and neural networks to design the feedback controller, used multilayer perceptron neural network to design the reference model and the ship course identification model network. Based on the fuzzy control and neural network, an intelligent adaptive control algorithm was presented in the paper. In consideration of the forces and moments from the environmental disturbance, such as winds, waves, currents, etc., Simulation experiments are carried out by using Matlab’s Simulink toolbox. The simulating result indicates the designed adaptive controller can get a good control performance for ship course tracking system.

Abstract: The power supply system of the LHCD heating systems of Tokamak (EAST) is required to be reliable and have good dynamic performances. In this thesis, an optimization model of the Single-module of PSM power source is proposed to analyze its dynamic performances theoretically and the special simulation tools in SIMPLORER are used for the modeling and simulation of the system.

Abstract: The output signal of pressure sensor installed in the dynamic weighing system for loader contains strong vibration, noise, nonlinear signal. The accuracy of the dynamic weighing system is closely related to the pressure signal. An empirical mode decomposition (EMD) algorithm is proposed to preprocessing the signal contaminated. The real weighing signal is filtered out. a new method based on neural network is used to predicate the nonlinear output. in order to solve the problem that it was easily to sink into the partial minimum , the genetic algorithm was put forward .The emulation analysis and the results show that by using the above method, measure precision within 1% can be obtained.

Abstract: With the development of economy, the acceleration of urbanization and the promotion of living standards, power users have put forward higher requirement of the power quality and reliability. The traditional methods of management can not satisfy the demands of users. Therefore, the power supply enterprises need to make use of the advanced technology to improve the technological and automation level. The marketing-distribution integrated system which takes the GIS platform as the basis, the users’ demands as the orientation, is comprehensive and cross-business application system. It can improve the level of management obviously. This paper proposes the construction aims, construction principles, the frame of information platform and application platform which are critical for the integration system.

Abstract: This paper aimed at the phenomenon of swing which caused by inertia force and outer loads when gantry crane worked, the dynamical equation and state space equation were founded based on Lagrange, analyzed the swing phenomenon by LQR linearity secondary optimal control method, and simulated the equation by MATLAB software, through the results, the conclusion can be got that this method could reduce time for crane swing and improve the precision of orientation and working efficiency, this method had important meaning for improve the security and working efficiency for gantry crane, which can be extended to other crane too.

Abstract: Critical Success Factors can be changed with the difference of industry, environment, business strategy, lifecycle of system, identification method and system, categorization and the study perspective of researchers. In the research of new high-tech enterprises consultation, it’s more valuable to discuss the Critical Success Factors and the orientation enhancing effect under the background of the lifecycle, value system and the classification of SWOT. Consulting the new high-tech enterprises under the background of “LC+CSF” will generate three kinds of prospective oriented aggrandizement, which are foreseeing enhancement of crucial problems, enhancement along the lifecycle track and foreseeing enhancement of the whole lifecycle. At the same time, consulting under the background of “VE+CSF” will generate four kinds of value orientation enhancement, which are type of function increasing relatively, type of cost reducing relatively, type of value upgrading and type of increasing methods applicability. Meanwhile, consulting in the situation of “SWOT+CSF” will make consulting judgment and consultation scheme be strengthened effectively along strategy and environmental orientation because of the application in the strategic quadrangle analysis affected by SWOT classification factors and CSF, factor intensity analysis and strategic situation analysis.

Abstract: The steady-state and transient performances of the power supply system of LHCD (Lower Hybrid Current Drive) heating system are highly demanded which makes it difficult to design the power source. In this thesis, the method of designing the 4.6GHZ/6MW power source of LHCD of EAST is discussed. And the results of the experiment are provided and some special characteristics are analysed to prove the accuracy of the method.
