利用Mindlin解，求解弹性半无限体内作用水平集中力引起的任一点的位移。(The soil movements of Mindlin solution introduced by a single horizontal force in semi-inifite plate.)

Advanced correlation filter synthesis algorithms to achieve rotation invariance are described. We use a specified form for the filter as the rotation invariance constraint and derive a general closed-form solution for a multiclass rotation-invariant filter that can recognize a number of different objects. By requiring the filter to minimize the average correlation plane energy, we produce a multiclass rotation invariant (RI) RI-MACE filter, which controls correlation plane sidelobes and improves discrimination against false targets. To improve noise performance, we require the filter to minimize a weighted sum of correlation plane signal and noise energy. Initial test results of all filters are provided

说明：  Today’s wireless networks are characterized by a fi xed spectrum assignment policy. However, a large portion of the assigned spectrum is used sporadically and geographical variations in the utilization of assigned spectrum ranges from 15 to 85 with a high variance in time. The limited available spectrum and the ineffi ciency in the spectrum usage neces- sitate a new communication paradigm to exploit the existing wireless spectrum opportunistically
