Study of a DC-DC Converter for Solar LED Street Lighting: Recently, light-emitting diodes (LEDs) are becoming increasingly attractive lighting sources in our daily lives. They are well suited to indoor and outdoor energy-saving lighting applications, such as general lighting, architectural lighting, traffic lighting, background lighting, displays, street lighting, automotive and motorcycle lighting, decorative lighting, and so on. The placement of street lights is closely related to the development of one area or region, and they represent the financial success of a city. For street lighting applications, the traditional lighting sources are high-pressure sodium lamps and high-pressure mercury lamps. Recently, LEDs are commonly being used as new sources for street lighting because of their attractive features of good lighting efficacy, energy-savings, that they are non-polluting to our environment, and that they offer a long lifetime in comparison to their traditional counterparts.

语音识别技术的最终目标是要让计算机能与人自由交谈。目前，连续语音识别技术正趋于成熟，语音识别也延伸出了诸多实用化的研究方向。今后，语音识别的重点将集中在自然话语识别与理解、实时语音识别和语音识别鲁棒性等方面。作为一门交叉学科，语音识别所涉及到的技术有信号处理、模式识别、概率论和信息论、发声机理、听觉机理和人工智能等。(The ultimate goal of speech recognition technology is to make computers and allowing others to speak freely. At present, continuous speech recognition technology is maturing, voice recognition is also extended out a lot of practical research directions. In the future, speech recognition will focus on Spontaneous Speech Recognition and Understanding, real-time speech recognition and speech recognition robustness and so on. As an interdisciplinary subject, speech recognition technology involved in a signal processing, pattern recognition, probability theory and information theory, vocal mechanism, hearing mechanism and artificial intelligence.)

仿真锁相环系统，可以仿真锁定时间。不同的环路带宽对系统的非理想特性！(PLL simulation system that can lock simulation time. Different loop bandwidth of the system of non-ideal characteristics!)

Delaunay triangulation is one of the most well known algorithms for space tesselation. Dynamic Delaunay triangulation, in which you can update the input points using a predefined matrice for saving points, is presented in this document.

说明：  给照片加相框，相框的边界可根据照片的尺寸自动调节，支持灰度和彩色jpg照片。(This code frames images with a beautiful frame. Automatically adjusts the bordering i.e. framing according to the image s dimensions. Works for both colored and gray images. )
