Various-type-of-image-compressionss
I have thoroughly study the basic of image compression techniques. From that I have selected SPIHT algorithm for my research work. I have implemented on image compression for gray images using SPIHT algorithm. Image compression is implemented using this algorithm has better result over the previous result on gray images and also improved PSNR value high but on other side low result on compression ratio.

MATLAB_qua
They are the programs of uniform quantization and non-uniform quantization.
In digital signal processing, quantization is the process of approximating ("mapping") a continuous range of values (or a very large set of possible discrete values) by a relatively small ("finite") set of ("values which can still take on continuous range") discrete symbols or integer values.

Discussion-of-raindrop-fall-speed
简单介绍雨滴的形成，运用流体力学相关知识，分析了雨滴下落所受的黏性阻力和压差阻力，考虑雨滴在空气中下落半径增加对雨滴速度的影响，得出了雨滴下落速度和雨滴半径的关系，对雨滴下落的收尾速度进行了一般的讨论。(Brief rain formation, the use of the knowledge of fluid mechanics, analysis of viscous drag and pressure drag the raindrops whereabouts suffered consider raindrops in the air, the whereabouts of the impact of increasing the radius of raindrops speed, to draw raindrops falling speed and raindrops radius the general analysis of the relationship between the terminal velocity of raindrops whereabouts.)
