单片机编程 基于ATmega48单片机的可调交流电子负载的设计
介绍一种无极可调交流电子负载设计的新方法，由ATmega48单片机输出PWM波，通过上位机设定不同的占空比控制场效应管的通断时间，即改变流过场效应管的平均电流。根据电流的大小，可以等效为相应的负载，并将采集的电流值显示在上位机上。文中对该系统的软﹑硬件设计思路作了详细的分析，阐述了其设计原理。

Coaxial feed structures are widely used in ultra-wide band antennas . This paper modeled the characteristic of the monopole antenna feeded by coaxial line by FDTD in the time-domiain,which showes that . Firstly, it introduced the theory of the arithmetic and the particularly realization in the calcu ...

im2dat.m is used to convert images to data which can be plotted using the standard MATLAB functions. This is very handy if you have plots on hardcopy and you want to convert them into data that MATLAB can use. The scanned image can be analysed by this function and the output will allow you to perfor ...

书籍 Power System Stability Modelling
Modern day large power systems are essentially dynamic systems with stringent
requirements of high reliability for the continuous availability of electricity.
Reliability is contingent on the power system retaining stable operation during
steady-state operation and also following disturbances. The s ...
