Q% ~- t!}7 f% n9 R; Z0 i8 Y$ S u Mussina has the best ERA (3.59). Johnson (17-10, 4.84) has the most experience. But Wang has by far the biggest gap between his home and road numbers. Mussina might be the most deserving of a Game1 start from a reward standpoint, but with a 3.83 road ERA, he is probably the best bet to pitch a good Game3 away from the Bronx.9 Q$ r. U. L5 G; c5 L; T
Moose的自责分3.59最低 Johnson (17-10, 4.84)则是最有季后赛经验而阿民则在主客场的数据上差距最大如果从报偿的观点来说 Mussinau是要获得第一场的先发荣誉的不过考虑到他的客场自责分只有3.83 他可能是不在纽约比赛的第三场最佳人选了

Using finite difference time domain method, the electromagnetic field distribution of THz wave is simulated in a THz 2D PC splitter and by plane wave expansion method the dispersion relation and defect modes are achieved in a THz rotated PC waveguide.5. A woodpile three-dimensional (3D) PC with face-centered-tetragonal symmetry is one of the most popular 3D PCs because of its favorable band gap characteristics. Based on the woodpile fct lattice structure, we propose a novel woodpile THz lattice structure with comparatively decreased symmetry, better band gap properties and easy fabrication by varying some structure parameters.

The main research contents are stated asfollow: 1. Simplified analysis method of space grids structuresDouble-layer space grids have been assumed as sandwich plate, and are analyzed bythe nontraditional theory of plate with consideration of shear deformation and threegeneralized displacements. Using the theory of energy variation, simplified methodsfor bending, stability and vibration analysis of double-layer space grids have been putforward based upon the idea of split rigidity.

Direct difference is sensitive to noisy data, so a threshold limitation is given, which can not only filter the result from noisy data but also pick edge points up according men's desire. On the other hand, artificial intelligence is used for segmentation in reverse engineering. Because the essence of segmentation is clustering similar characteristics and self-organizing feature mapping is one function of neural network, SOFM network is used for segmentation in the thesis, coordinates and normal of data points is took as the characteristics vector.
第二种方法,基于双向角度微分的边点提取法,针对三维正交模型采用基于截面线的方式组织数据,此方法比基于曲率半径方法更简洁,不用进行曲面拟合,大大提高了计算速度;计算过程中由数据点的直接差分逼近微分,但直接差分对数据误差敏感,为此,本文提出了阈值过滤的方法,一方面过滤了数据误差在计算结果中引起的噪音,另一方面可以按照设计意图控制边点的提取;来决定是否提取光滑交接的边点。
