RS232-Communication

使用matlab书籍，简单易学，对初学者来说是很不错的一本书(a book for matlab user. It is simple to understand and easy to get into using it.)

说明：  很不错的一本英文书籍，全面详细的讲解了simulink，从基础到进阶到高级应用。(Simulation and Model-Based Design 1.What Is Simulink? 2.Building a Model 3.How Simulink Works 4.Simulink Basics.......)

当二值图像中的文字倾斜时，该程序可调节任意倾斜方向的文字变为水平，从而实现图像的倾斜校正。(When the text in the binary image is tilted, the program can adjust the tilt direction of the text into any level, in order to achieve the image tilt correction.)

Wireless Sensor Networks have been proposed for a multitude of location-dependent applications. For such systems, the cost and limitations of the hardware on sensing nodes prevent the use of range-based localization schemes that depend on absolute pointto- point distance estimates. Because coarse accuracy is sufficient for most sensor network applications, solutions in range-free localization are being pursued as a cost-effective alternative to more expensive range-based approaches.

说明：  matlab高阶谱（双谱）分析直接法和间接法，可用于时差估计等(matlab order spectrum (bispectrum) of the direct method)

一种求解基础矩阵的方法，matlab实现(Solving the fundamental matrix method, matlab achieve)

龙贝格积分，MATLAB程序，计算方法作业，内有说明(Romberg integration, MATLAB procedures, calculation methods work, there are instructions)

小波包的分层和提取特征，提供给大家参考，在研究小波中。(Layered and extract wavelet packet provided for your reference in the study wavelet.)

Modern wireless device have sleep mode which greatly reduce the duty cycle of the power supply.Consider the effect of different duty cycles and transmit times to see the wide range of battery lifetimes one may expect before recharging. results is being plotted of battery lifetime as a function of the duty cycles & duration of the wake up mode.
