Conductive polymer composites (CPCs) have generated significant academic and industrial interest due to the wide applications in anti‐static materials, electromagnetic interface, sensor, and conductors. Nonetheless, the CPCs fabricated by conventional melt‐mixing applied to the scalable production generally have a very high percolation threshold, which always suffer from the various draw backs such...
Driving safety and traffic efficiency have always been the research focuses for signalized intersection. This study proposes a braking assistance algorithm, which is developed to help driver brake with a smooth braking process and appropriate stopping distance at signalized intersection as human driver does. The system is required to take human driver's individual differences into consideration. Thus,...
Nowadays it becomes more serious to improve transient stability of power system as the grid is becoming larger and more complex gradually. This paper presents a new automatic real-time power modulation strategy of High Voltage Direct Current (HVDC) based on Extended Equal Area Criterion (EEAC) and Bang-Bang Control (BBC) strategy to improve transient stability of power system. The proposed strategy...
This paper presents an automatic bang-bang control strategy of HVDC power flow based on equal-area criterion. The proposed strategy has taken into account the restraints on both amplitude of power flow change, and rate of change. This strategy is evaluated on an AC/DC system model in EMTDC/PSCAD. Simulations with several faults in different places show that the proposed strategy allows a significant...
Personalized meta-search engine is one search engine that we teach the machine to learn users' interest, so the search engine can help users to pick up the useful information for them quickly by using their interest keeping in the database. Personalized meta-search engine can sort the results according to users' interest, the results that user likes will be the top of the results. It is a good measure...
The social search engine, as the meaning of its name, combines the SNS (Social Network Service) and search engine. Its key point is not at social, but at the search engine. The system will use the SNS to help users to get their useful information quickly and accurately. This paper mainly introduces the value of social search engine, forecast and the problem may meet in the future.
As growing network information, as well as the limitations of traditional search engines, so that people searching for information using traditional search engine, the difficulty greatly increased. We have developed a Meta search engine, which can be automatic classification of information, users use this search engine to search for information; on the one hand can guarantee the recall of information...
To improve the feasibility and precision of vehicle dispatch results, a pseudo normal distribution membership function of fuzzy velocity is proposed based on traffic data simulation in typical roads in Beijing. The VRPB (vehicle routing problem with backhauls) under time-division fuzzy velocity is described, mathematic model is set up. Tabu search algorithm is used to solve the problem. The application...
