Abstract:When self-scanned photodiode array image sensors are applied in object measurements, the outer sizes of the object are included in the video signal of image sensors. The identification and measurement of the object ,and the enhancement of the performance is depended on the symbol extraction of the video output signals. Based on the working principles of self-scanned photodiode array image sensors, the mathematical models of image sensor's video signals are established when the moving object is captured. The comparative method and the measurement error are researched. The results of this paper provide a theoretic basis for the research of video signals processing.

Abstract:When analysing the performance of casting powders in a specific casting machine, the thickness of liquid slag is a very important parameter. If the liquid slag thickness is not kept above a certain minimum value during the continuous casting operation,the surface and internal quality of the cast products will be jeopardised because lubrication between the strand and the mould is impaired . It is necessary, therefore , to choose the appropriate type of mould powder .In the industrial experiments, it is very difficult and expensive to study this sensitivity by introducing controlled variation in one parameter while keeping all the other constant. Numerical and computer simulation methods are used in the study .They can predict the liquid slag thickness developed above the liquid steel and distribution of the temperature. The sensitivity of the liquid slag thickness to variations can be determined in the material properties of the mould powders.

Abstract:ip-iq法能准确、实时地检测不对称三相系统中的有害电流，被广泛应用于三相电力有源滤波器，目前，在检测不对称三相四线系统的有害电流时，均事先剔除零序电流，然后再采用ip-iq法，通过理论分析证明，ip-iq法经过3/2变换后iα、 iβ中都不含零序电流分量，并且基波正序分量不会受到影响，因此含有3/2变换的p-q法、d-q法、ip-iq法都不会受到零序电流的影响，所以这些检测方法都不用先剔除零序电流而直接用于不对称三相四线系统有害电流检测。理论和仿真结果表明这种方法能正确检测出基波零库、负序及谐波分量，从而改变了长期以来认为ip-iq不能直接用于三相四线系统的观点。

Abstract:In short term load forecasting based on ANN,weather is one of the important factors which impacts on load greatly. In order to capture the effect of weather on load, this paper presents a novel thought based on ANN and trends combination short term load forecasting. Decompose the underlying relationships between load and weather variables into three main trends of weekly, daily and hourly. Three separated ANNs capture each trend. Another ANN to arrive at the final forecast combines the forecasts yielded by individual ANNs. The performances of the proposed model and the traditional model are compared on the basis of one week ahead hourly forecasts. Results indicate that the proposed ANN based model can achieve greater forecasting accuracy than the traditional ANN based model.

Abstract:Quoting price is an important technology in the process of logistic company. The degree of the price has direct effect on the enterprise's profit, and whose correctness influences whether an enterprise can hold its client. In the operation of ship, due to the phenomenon of empty container, it is difficult to decide the quoted price to use the traditional quoting method based on the cost, because if the price is too high, the client can't accept it, but if the price is too low, it can't ensure an enterprise's profit. In this article, we will apply the economy meaning of shadow profit in the corresponding theory to resolve the problem of quoting price in the phenomenon of empty containers in operation of ship. The profit model and correspond opposite model are built, the theory and meaning of shadow benefit are discussed, and some classified formulae and quoting guide lines based on shadow profit are proposed. An example will be used to prove that the quoting theory based on shadow profit can validly direct the quoting price of logistic company for the added goods in the phenomenon of empty container.

At the same time, the transient heat transfer characteristics of the MSW lump decides the stay time of the MSW in incinerator and effects on the operation feature of the combustion equipments. All of these would lead to design the reasonable and clean combustion project, the optimum incinerator and recover energy system. The component, shape, dimension, property, the hardly and inner structure feature of the MSW lump are taken in account, and the effective conduct heat coefficient has been adopted. And then, the physical model is setup with different shape(ball, cylinder, squareness), and the 3-D mathematical model and conduct heat efficient with porous feature for transient heat transfer of MSW lump are presented, at the same time, the simulation tests are gotten in various boundary and the interesting conclusions are gotten: The center stable temperature of the MSW lump is mostly decided by the inner gas temperature of the incinerator and the heated area of the lump. The transient heat transfer characteristics is variously effected by the shape of the MSW lump in incinerator. The transient process becomes longer and the center stable temperature decreases, the volatile can't be easily separated out and the combustion efficiency decreases because of the increasing of the lump feature dimension.

To deal with the problem of moral hazard, it is necessary to choose the proper investment tool and compensation policy. A game model is set up, which helps to study which tool is the best investment tool among debt, common stock, convertible preferred stock and convertible debt, given the venture entrepreneurs can be made work hard. By the analysis of the model, a fact can be found that convertible preferred stock and convertible debt is the best way if the better result is twice larger than the original capital. Otherwise, the form of debt will be better.
