摘要：
Relative position between processing factor of processed spares and machining cutter to be fixed and maintained is the main function of machining fixture, which is decomposed location function and clamp function and connection function between machining and its fixture and presetter and introduction function as well as division function in this paper, Consequently function tree of machining fixture design to be formed. Morphological matrix of conceptual design for drilling fixture is constructed according to function tree of machining fixture design and its specific design requirements. Concept of fuzzy distance measure is introduced to decide the final ranking of alternatives. To avoid the combination explosion, an algorithm-based heuristic solving strategy is subsequently proposed by defining the heuristic evaluation function as a fuzzy multi-criteria decision-making.

摘要：
Genetic programming (GP) is an illogical method for automatic programming. It shows creativity in discovering a desired program to solve problem, but in essence bases its searching principle on software testing. This paper is dedicated to establishing a novel GP which combines classical GP and formal approaches like Hoarepsilas logic, model checking, and automaton, etc. The result indicates these methods can collaborate in the framework pretty well. As has been demonstrated by the experiment, they work in a way that preserves their advantages while each compensates for the deficiencies of the other. So, once an approximate program is obtained, we can say with certainty it is correct with respect to its corresponding pre- and post-conditions.

摘要：
The focus of this paper is on the segmentation algorithm for the high resolution multispectral imagery to get regions which are roughly corresponding to land cover types. We propose the combination of spectral features and spatial features by Gabor filter banks and a variable mean shift clustering algorithm in high dimension is employed to achieve feature fusion. Some issues on the measure metric of different features and standilzation are discussed. The whole algorithm is evaluated on the synthetic texture image, which are cropped from a QuickBird image with typical land-cover types. Compared with fixed bandwidth Mean Shift segmentation algorithm, our method has better performance in distinguishing the different land cover types with similar spectral surface.

摘要：
ART2 proposed by Carpenter and Grossberg is a self-organizing artificial neural network based adaptive resonance theory. There is vast potential for the characteristics of its imitating the Human brain nerve system working in neurophysiology and psychology. But learning rate of ART2 can not be adjusted directly, model drift phenomenon of ART2 network occurs frequently. To solve this problem, this paper discusses the common-used learning rules of ART2 network at first and then it points out that although there is no learning rate in these learning rules as other artificial neural networks, but it implicitly exists. The way to adjust the learning rate is suggested and the suppression to pattern drift is verified by a vector learning trial. The categorization results to lris dataset are also compared to illustrate the function of learning rate.

摘要：
Bus priority control at isolated intersection was discussed in this paper, passive priority and presignal were researched and compared. Average delay per vehicle (ADPV) and average delay per passenger (ADPP) were selected as the efficiency indexes of system. VISSIM 4.10 was selected as the evaluation tool. Simulation model was constructed relating to one real intersection. Simulation results indicated that pre signal can reduce ADPP by 4 to 15 percents and increase ADPV by 7 to 30 percents. Also, scene of bus advance area, signal timing of the main signal can influence efficiency of the system.

摘要：
With the development of the mechanization and automation, the defects of the traditional decision-making model of product portfolio emerge increasingly. At the same time, the extreme assumptions of Activity-based Costing and Theory of Constraints which are using now make the result of decision making become distortional. And some linear programming models based on these theories do not consider product market opportunity synthetically yet. To make up the defects of lacking considering the market competitiveness and to make the decision-making model become more rational and practical, the enterprises need to consider the product acceptance in market and the processing cost of the unacceptable product synthetically when they make the decision of the best product portfolio. The optimization model this paper proposes should be more valid and feasible for enterprise decision-making of product portfolio in strong market competition.

摘要：
When Minsky developed the financial instability hypotheses, he classified economic units into three categories which are labeled as hedge, speculative, and Ponzi finance. The weight distribution among the three determines the degree of fragibility in financial system. According to Minsky, the instability of the stock market for A shares is dominated by the weight of speculative, and Ponzi financing units. Under the Minskyian framework, among 46 listed sample companies in Shanghai Security 50 Index for A shares, the proportions of hedge financial units, speculative units wererespectively 50％-67％ and 33％-50％ in 2006, with the latter having a capital gap, and there were no Ponzi financial units. In a financial aspect, 50％ out of 46 entities were lack of the ability to repay debts matured in 2006, and 20％ out of them had not repaid actually the debts matured. These empirical data meant that there was fragibility in Shanghai Security Exchange for A shares.

摘要：
A lot of research has been made on space vector modulation (SVM) strategy of matrix converter (MC), but research on over modulation strategy of MC is almost blank. This paper analyzed conventional control theory of dual-bridge MC, derived voltage transmission characteristic, then presented an over modulation method. At first, the rectifier is over modulated to get the greatest DC voltage, then the inverter is modulated from linear region to six-step mode seamlessly, which effectively improve the voltage utilization. Voltage transfer ratio under different conditions is emphatically analyzed with Fourier transform. Finally, different modulation method is simulated with MATLAB. Both math analyses and simulation results verify that the over modulation strategy is very useful to improve voltage utilization, which provide a theoretical basis for further research.

摘要：
An adaptive algorithm of multi-point iterative method for simultaneous determination of all roots of polynomial equation is obtained. Its convergence rule was presented and proved. The computation is carried out by simple steepest descent rule with adaptive variable step-size. The specific examples illustrated that the proposed method can find simultaneously the roots of polynomials at a very rapid convergence and very high accuracy with less computation.
