Spatial geometric deformation is the core technology of surface modeling. Implement quadric modeling by modified basic entity or existing models. In order to avoid low effectiveness which is brought by operating underlying geometric primitives directly, two key problems need to be solved. These are selecting the appropriate features of the mannequin as a basis for deformation and modifying mannequin...
Web hot topic prediction is now one of the most significant research focus in Web data mining, which can reflect the Internet users' psychosocial predilection, may greatly benefit us. Markov and neural network are such two typical traditional prediction model, however, the Markov method can neither capture nor express the statistical property of the real data while the computation of neural network...
With the increasing business in air travel area, reducing the plane's turnaround time is becoming more and more important. In this paper, it chooses the optimum boarding strategy to reduce the turnaround time. The MINPL model is for the small-size plane, with the boarding time mainly depending on seat interference and aisle interference. The GASimplex algorithm (genetic algorithms mixed with simplex...
An improved narrowband high frequency (NBHF) channel model is presented based on the ITS wideband high frequency (WBHF) channel model. Through proper simplification, an implementation method fits for computer simulation is provided. This new simulation model eliminates one of the limitations of the Watterson NBHF channel model. It can be applied to a wide range of channel conditions.
The steel grounding grid buried in earth will corrode and become hidden danger to the safety of power system. It is difficult to get accurate status of corroded ground grid with traditional method. A novel method is presented in order to improve the efficiency and precision of diagnosis. A sine wave exciting current of different power frequency is injected directly into grounding grid by two ground...
Optimization of interruption performance in high voltage circuit breaker is mainly the optimization of dielectric recovery, among which the nozzle optimization occupies an important position. Because the optimization of dielectric recovery involves numerical calculation of electric field and flow field, time consuming becomes the bottleneck of nozzle optimization. Therefore, a new calculation method...
In this paper, we compare the efficacy of a variety of language models (LMs) for rescoring word graphs and N-best lists generated by a large vocabulary continuous speech recognizer. These LMs differ based on the level of knowledge used (word, lexical features, syntax) and the type of integration of that knowledge (tight or loose). The trigram LM incorporates word level information; our Part-of-Speech...
