According to the limitation of Principal Components Analysis in dealing with the nonlinear data, connecting with the Linear Programming Techniques for Multidimensional Analysis of Preference, this paper presents the Kernel Principal Components Analysis-Linear Programming Techniques for Multidimensional Analysis of Preference evaluation model. Kernel function maps linear inseparable input data into a high dimensional linear separable feature space via a nonlinear mapping technique. Then it carries on the linear principal components analysis in the high dimensional feature space. In addition, the weight of each index can be obtained in this model, thus it makes up another shortage of Principal Components Analysis. In the wastewater evaluation, the indices are numerous and the degree of correlation is not high, therefore, this model is more appropriate. Finally, this paper applies the model to the wastewater evaluation in Shanghai, and we obtain better evaluation results. [ABSTRACT FROM AUTHOR]

Coopetition is a revolutionary mindset, which combines competition and cooperation. It is based on the principles of the game theory and the belief that "You can't do it alone". It is a reflection of interdependence between competing organizations. It is generally agreed that most organizations are competing in a red ocean. Kim and Mauborgne, suggested another strategy called "Blue Ocean Strategy" which aims to escape from bloody competition and develop a new market by value innovation. Coopetition is one of the blue ocean strategies, which help to create uncontested market space and make competition irrelevant. This paper aims to explore the current situation of coopetition in Hong Kong. In this paper a survey was conducted to investigate the current practices and the critical success factors of coopetition in Hong Kong. [ABSTRACT FROM AUTHOR]

Little is known about Chinese software development. In this paper, we report on the status of requirements management within six Chinese companies. We investigate the pre-implementation phases on business and engineering levels and documentation utilized within the whole development process. [ABSTRACT FROM AUTHOR]

According to statistics from the State Environmental Protection Administration of China, China's daily electronic waste output adds up to 3,000 tons. The accelerating technological redundancy turnaround times are making the waste problem even worse. In addition to this domestic garbage, vast amounts of overseas electronic wastes, most of them are imported officially as "secondhand goods". However, safe recycling operations are not currently viable in China. So the important thing is to make the electronic scrap recycling process profitable and safety to avoid the secondary pollution. This paper proposes a cost-efficient management of material flows which can help recycling companies obtained more achievable marginal income. [ABSTRACT FROM AUTHOR]

An online handwriting Tibetan character recognition scheme of syllable-base association is proposed in the paper. First basic characteristics of the Tibetan language of letter, character, syllable and word are explained, and the different writing styles are introduced as well. At the some time, character's characteristics as recognition unit in our study are analyzed. In the proposed syllable association scheme, not only recognition speed but also recognition veracity is separately improved after isolated character recognized in our online handwriting Tibetan character recognition system. The research show, if adopt effectual method to improve the recognition rate of isolated character, the method will bring into play a more efficiency. [ABSTRACT FROM AUTHOR]

After the outbreak of 2003 SARS in Hong Kong, drainage has been considered as a path of virus transmission. When the floor trap has no water seal, smell can come through the drainage pipe. Loss of water seal of the trap can be caused by excess air pressure within drainage pipe especially in the stack of drainage. It is very difficult to make assessment on air pressure profile within stack and a prediction model is required. In this paper we will review and develop assessment models using experiment method. Partial differential equations predicting the air pressure profile within stack are used. The pressure profile shows positive and negative air pressures zones with respect to heights of discharge points, which are key elements to form a drainage monitoring system of a real building. A risk assessment protocol is developed to monitor the degree of water seal oscillation. [ABSTRACT FROM AUTHOR]

In the unilateral open electricity market in China, the current management method of the balance account, which is regarded as "regulator" between the bidding price of generation and retail price of electricity, has serious defects and might lead to the huge shortfall of the capital at the account and endanger the operation of market steadily. Based on incentive compatible principle, a new method through reward-punishment for the balance account management is presented in the paper and the optimal bidding strategy of power suppliers considering the new management method of the balance account is also provided. The test results indicate that the bidding strategy proposed can inhibit the market power of the generation, reduce significantly the market clearing price and keep the capital of the balance account fluctuation within a certain range, which ensures the power market to operate steadily and safely.

Registration becomes difficult when the concerned pattern, e.g., a Chinese seal pattern, is noisy and rotated. In this paper, an approach to Chinese seal registration that is widely used in many commercial applications in Chinese society is presented. For a color image, a SOM algorithm and a simple color filtering process are applied for seal segmentation. Then a contouring analysis is performed on the segmented seal to detect its principal orientation. Finally, the registration is achieved by combining the orientation difference and the center region translation vector for two seals. Experiments on seals having rotations, heavy noise, and different resolutions confirm the feasibility of the proposed approach. [ABSTRACT FROM AUTHOR]

This paper presents a real time simulation model of hydropower plant protective relaying systems. In this model, the full-scale protection system is composed of sub-protective-systems for each electric device in a hydropower plant, and each sub-protective-system consists of several components of protective relaying with different functions. To meet the real time simulation requirement, a general relaying model is developed to model a versatile protective relay, and a specific protective relay can be modeled through initialization of the general relaying model with different specific parameters and coordination settings. By using these, the simulation modeling is much simple, and the computation time can be reduced enormously. This real time simulation model of protective system is successfully used in the hydropower plant operator-training simulator in the Hydropower Plant Simulation Laboratory -- the key laboratory of the State Power Cooperation of China.
