Many good textbooks exist on probability and random processes written at the under- graduate level to the research level. However, there is no one handy and ready book that explains most of the essential topics, such as random variables and most of their frequently used discrete and continuous proba ...

When 3GPP started standardizing the IMS a few years ago, most analysts expected the number of IMS deploymentsto grow dramatically as soon the initial IMS specifications were ready (3GPP Release 5 was functionallyfrozenin the first half of 2002and completedshortly after that). While those predictions ...

I am presenting this novel book on advances and trends in power electronics and motor drives to the professional community with the expectation that it will be given the same wide and enthusiastic acceptance by practicing engineers, R&D professionals, univer- sity professors, and even graduate stude ...

用的是沁恒CH552e淘宝买的评估板，USB中断上传程序用的是沁恒提供的做了些修改。程序使用2个端点一个，端点1作为普通键盘，端点2作为多媒体按键，有详细注释多媒体按键报告，以下是主函数内容。/****主函数****/main(){    CfgFsys( ); //CH552时钟选择配置    mDelaymS(5); //修改主频等待内部晶振稳 ...

Mathematical modeling has become an important part of the research and devclopment work in engineering and scicnce. Retaining a competitive edge requiresa fast path between ideas and prototypes, and in this regard mathematical modeling and simulation provide a valuable shortcut for understanding bot ...

蓝牙低能耗（Bluetooth Low Energy，或称Bluetooth LE、BLE，旧商标Bluetooth Smart）也称低功耗蓝牙，是蓝牙技术联盟设计和销售的一种个人局域网技术，旨在用于医疗保健、运动健身、信标、安防、家庭娱乐等领域的新兴应用。相较经典蓝牙，低功耗蓝牙旨在保持同等通信范围的同时显著降低功耗和成本011年，蓝牙技术联盟（SIG ...
