P-Q-method-of-power-flow-calculation
MATLAB编写利用P-Q分解法的潮流计算程序，程序中利用基于稀疏技术的因子表法进行迭代求解，以降低存储量，提高运算速度。本程序只适用于简单系统，如IEEE5节点系统。对于复杂系统，由于PV节点电压越限等问题尚未考虑，得到的潮流结果可能有误！(MATLAB flow calculation program written using PQ decomposition method, program utilization based on sparse iterative solver technology factor table method to reduce the storage capacity, improve processing speed. This procedure applies only to simple systems, such as IEEE5 node system. For complex systems, PV node voltage due to the more limited issues not yet considered, the trend of the results obtained might be wrong!)

程序采用的是两层循环上实现位移谱的求取。内循环实现在地震波下由上一步所得到的位移、速度和加速度得到下一时间间隔后的位移速度和加速度；外循环实现在不同结构自振周期（频率）下遭遇地震波的响应。(Program uses a two-layer loop on calculate displacement spectra. Cycle based on seismic waves obtained the previous step under the displacement, velocity and acceleration are next after the interval velocity and Acceleration outer loop implementation in different natural period of structure (frequency) the response under earthquake wave.)

文利用带噪语音经特征基函数矩阵转换后所具有的稀疏特性，用最大似然估计方法对转换后得到的稀疏分量进行非线性压缩去噪，然后再经过反变换和重构恢复出原始语音信号的估计。特征基函数矩阵反映了语音数据本身的统计特性，因此具有很好的合理性和可取性。仿真结果表明利用稀疏编码方法能极大程度地抑制背景噪卢，与小波消噪法相比优势明显。(a speech enhancement algorithm based Compressed Sensing.)
