It is a matlab code for detecting brain tumor in MR images using CIELAB color space model segmentation.

本文講述了一個基於FAN4800 連續PFC 前端的雙管正激電源的功率級設計。回顧了這種電源的設計選擇。討論的實際課題包括功 率器件選型，電磁設計，佈局和電磁干擾 (EMI)，目的在於幫助工程師加速並改善其設計。(This article about a front-end based on the FAN4800 PFC consecutive two-transistor forward power stage power supply design. Review this power supply design options. The actual topics discussed include the selection of power devices, electromagnetic design, layout, and electromagnetic interference (EMI), designed to help engineers to speed up and improve its design.)

NSGA_II多目标优化算法，用于工程优化计算，很好很强大(NSGA_II)

本程序用于测量增强语音与纯净语音的对数谱距离，用于语音增强。对数谱距离越小，表明增强语音与纯净语音越接近，增强语音质量越好；反之，则增强语音质量越差。(Calculates the average log-spectral distance between CLEAN and NOISY signals. Frames are 25ms long with 60 percent (15ms) overlap, hamming windowed. RS is the remove silence option (default: 0) if 1, the program uses a Voice Activity Detector to find non-speech frames and eliminates them from calculation of LSD. FS is the sampling frequency (Default 10KHz). )
