FFT2

QR分解的编码，可以直观的看到编码的过程(base on OR)

DEA编程用于分析决策单元是否是有效地，进而作进一步分析(DEA program for the analysis of decision-making unit is to be effective, then further analysis)

本文首先推导出过采样滤波器组精确重构的条件, 由于此时所需的约束条件数比临界采 样时少, 因而可以设计出频域衰减特性更好的滤波器组(This paper is derived through sampling filters of exact reconstruction of conditions, due to time constraints required for critical extraction ratio When a small sample, so you can design a better frequency filter attenuation characteristics)

Active Shape Models 的创始人 T.F.Cootes的几篇重要论文(the founder of the T. F. Cootes several important papers)

IEEE57节点电力系统标准参数和潮流数据(IEEE57 node power system standard parameters and trend data)

计算电力系统稳态潮流，使用直角坐标下的牛拉法，用牛顿迭代求解非线性方程组。计算结果包括节点电压、发电机注入功率、负荷注入功率支路始端功率、支路末端功率、支路损耗、网络损耗 (Calculation of the steady-state trend of power system, using ox-drawn in the rectangular coordinate method for solving nonlinear equations using Newton iteration. The calculation includes the node voltage of the generator into the power load to inject power slip began end power, slip the end of the power branch outages, network connectivity loss)
