2007年 ion gnss 会议，斯坦福大学的学生做的关在在电离层风暴中laas系统安全的相关分析

The AP2406 is a 1.5Mhz constant frequency, slope compensated current mode PWM step-down converter. The device integrates a main switch and a synchronous rectifier for high efficiency without an external Schottky diode. It is ideal for powering portable equipment that runs from a single cell lithium- ...

Lithium–sulfur (Li–S) batteries with high energy density and long cycle life are considered to be one of the most promising next-generation energy-storage systems beyond routine lithium-ion batteries. Various approaches have been proposed to break down technical barriers in Li–S battery systems. ...

I2C(Inter Integrated Circuits)是Philips公司开发的用于芯片之间连接的串行总线，以其严格的规范、卓越的性能、简便的操作和众多带I2C接口的外围器件而得到广泛的应用并受到普遍的欢迎。 现场可编程门阵列(FPGA)设计灵活、速度快，在数字专用集成电路的设计中得到了广泛的应用。本论文主要讨论了如何利用Verilog/FPGA来实 ...
