作者： Lin Li 1st School of Business East china University of Science and Technology Shanghai china 200237 Lele Wang 2nd Financial engineering Department Institute of Shanghai Securities co. ltd.Shanghai china 200001

the aim of paper is to use Genetic algorithm and Monte Carlo to price co.vertible bond with finite maturity. As we known, Monte Carlo is hardly applied to price the derivatives with optimal items. co.bined with Genetic algorithm and Cubic sample function, Monte Carlo not only solves the co.vertible bond with optimal co.version items, but also prices that with long-range dependence property. By evaluating the co.trolling points of cubic sample function, the optimal co.vertible boundary is showed. Furthermore, the proposed method can be applied to price derivatives with optimal items, such as American option and optimal investment with muti-risky assets.

2011 international co.ference on Advanced Power System Automation and Protection(APAP 2011)

There is a power micro grid co.posed of several diesel generators, cables, step-down transformers and motors. The similar grid scheme is applied to airports, mining plant, and oil platforms etc. In the micro grid, the generating system needs to meet the demands not only for supplying stable electricity, but also for keeping the islanding operation. As we know, damages of generator stator insulation easily happen due to the generator arcing ground current beyond the limit. In this paper, naturally it is available that high resistance grounding is used at one of several direct-co.nected generators neutral in a micro grid, and to keep only one generator grounding at a time among them in parallel, there is one automatic isolator at each generator neutral by the generator co.trol system. Further, the protection co.ordination basing on this grounding method that is reliable earth-fault protection scheme has been used to this micro grid. The neutral grounding method, the protection co.figuration of feeders, generators and buses, and partly the settings calculation of the relay device are introduced and analyzed in this paper, and the available co.plete scheme has been adopted.

＜正＞A new theoretical model is presented because of the limitation in traditional theoretical model of the high voltage direct current method for leakage detection of landfills, which treats the single liner landfill as infinite three-layer even medium in horizontal direction, regarding the current flowing through a leak as a superposition result of the negative current source located at the feed-in side and the positive current source located at the feed-out side. The potential distribution pattern in every layer medium in this model is forward modeled. Acco.ding to the basic characteristic of this model, the results are simplified. The results indicate that the potential distribution of the electric field in half infinite space in the three-layer medium model agrees with that in the infinite medium space of half space model.
