When increasing the frequency, inductive effects start to limit the currentand skin effect makes it increasingly difficult to resolve the current distribution in thewinding. At sufficiently high frequency, the current is mainly flowing in a thin layernear the conductor surface. When increasing the frequency further. capacitive effectscome into play and current is flowing across the winding as displacement currentdensity. When going through the resonance frequency, the device goes from behavingas an inductor to become predominantly capacitive. At the self resonance, the resistivelosses peak due to the large internal currents Figure 4 shows the surface current3 MODELING OF A 3D INDUCTORSolved with COMSOL Multiphysics 5.0distribution atl MHz.

图像分割是目标识别的首要和关键步骤。目前的图像分割方法有多种, 其中阈值方法优点比较突出, 但是采用阈值方法分割的关键是要能高效率地找到被分图像的最佳熵阈值。针对这一问题, 将Geese- LDW- PSO 算法的位置更新公式作了改进, 即用当前种群的全局极值取代所有粒子的当前位置, 并将之用于熵阈值图像分割中。仿真实验表明, 该算法可以快速稳定地获得一幅图像的最佳分割阈值。仿真结果显示, 该方法对车牌分割具有较好的性能。专业论文，为广大做毕设同学提供资源
