The authors interpret four remote sensing images using of EDARS8.5 based on field trips and previous data, then get the wetland resource database of the Yellow River Delta in 1985,1996,2000,2004. Carried out in Arcview3.3 overlay analysis, we calculate the 1985–2004 Yellow River Delta wetland transition probability matrix, then analysis the spatial structure changes of the Yellow River Delta wetland...
Under the financial crisis, it is important for China to make use of public-private partnerships (PPP) for infrastructure construction. This paper emphasizes multi-task bundling of PPP on the condition of incomplete contracts and asymmetric information, involving the bundling of two tasks of building and operating infrastructures used for the provision of public services, as well as that of three...
The competition of contemporary automotive market has evolved from competition between enterprises to competition between industry value chain (IVC). Based on the theory of IVC, this paper explains the relationship between extension of value chain and enhancing competition of China's automotive industry. Through analysis of developmental mode of US and Japan's automotive industry, propose the strategic...
The brushless DC motor (BLDCM) has a good control performance. The classical PI controller is widely used controller. But the determining of its parameter needs the mathematical model of the system. Usually the exact mathematical model of system is hard to known. This places a restriction on the applying of the commonly used Z-N method to determine the parameters. Also the parameter determined by...
An fuzzy gain based adaptive fuzzy logic controller (FLC) is developed for the speed control of brushless DC motor (BLDCM) drive in this paper. In a FLC, the way to improve the performance of the FLC is to tune the fuzzy rules, membership function and scaling gains of inputs and output. The scaling gains of the inputs and output of the proposed fuzzy controller are parameters that can be tuned conveniently...
In order to minimize the volume of HTS magnets and reduce the perpendicular component of magnetic field, two optimal algorithms- iterative algorithm and genetic algorithm are presented to make optimal design of geometry parameter of HTS magnets. The example of optimal design of 500kJ HTS magnet is also given. And the comparison between iterative algorithm and genetic algorithm has done. The iterative...
