说明：  潮流计算，使用PQ分解法，是一种比牛顿法更优越的潮流计算法，收敛速度更快，收敛精度与牛顿法相同(power flow of P-Q)

此文件夹为七单元线阵的波达方向（music罚法）估计程序，包含不加平滑的估计程序和加上前向平滑的估计程序。程序中每部分都有详细的中文注释，非常容易理解，特别适合于初学者。是本人学习波达方向估计时的心得，希望对大家有帮助。(This folder linear array of seven units of DOA (music Penalty Act) estimation procedures, including without smoothing estimation procedures and smooth with the forward estimates process. Each part of the program are detailed notes in Chinese, is very easy to understand, especially for beginners. DOA estimation is when I am learning experiences, we want to help.)

为研究局部阴影效应对光伏发电系统的影响，首先建立了光伏阵列工程数学模型，分析局部阴影条件下光伏阵列的输出特性。为了便于工程分析，该文利用PVSYST软件分析比较单晶硅、多晶硅和薄膜电池等3种不同材料光伏电池在局部阴影条件卜的输出功率，为工程应用提供了良好的指导作用。最后提出了几种提高光伏阵列抗局部阴影能力的措施厂 (To investigate the effect of local shading effects on photovoltaic systems, photovoltaic array project was first established mathematical model to analyze the output characteristics under conditions of partial shading of the PV array. In order to facilitate engineering analysis, this paper use PVSYST software analysis and comparison monocrystalline, polycrystalline and thin film batteries, photovoltaic cells of three different materials in partial shade conditions Bu output power for engineering applications provide a good guide. Finally, several photovoltaic arrays to improve the ability to measure resistance to partial shade plant)

Abstract—In this paper, a new lossy technique based on wavelet transform for compression of breast ultrasound images is presented. The experiments are performed on 16 different wavelet functions and the quality of reconstructed images is evaluated by using Compression Ratio (CR), Normalized Mean Square Error (NMSE), Normalized Absolute Error (NAE), and Peak Signal to Noise Ratio (PSNR) criterion. An ultrasonographer performed the subjective assessment. This study shows that among the utilized wavelets,

This code has been used and seems to be free of error. However, it carries no explicit or implicit guarantee.
