This book has grown out of my teaching and research at the University of Surrey and out of my previous experiences in companies such as Philips, Ascom and Motorola. It is primarily intended for use by students in master’s level and enhanced final-year under- graduate courses who are specialising in communication systems and wish to understand the principles and current practices of the wireless communication channel, including both antenna and propagation aspects

This is believed to be the first book that takes a view of nanotechnology from a telecommunications and networking perspective. Nanotechnology refers to the manip- ulation of materials at the atomic or molecular level. Nanotechnology is getting a lot of attention of late not only in academic settings and in laboratories around the world, but also in government and venture capitalists’ initiatives. There now is a major drive to commercialize the technology by all sorts of firms, ranging from start- ups to Fortune 100 companies.

This book provides a comprehensive overview of the technology behind the pico-solar revolution and offers guidance on how to test and choose quality products. The book also discusses how pioneering companies and initiatives are overcoming challenges to reach scale in the market- place, from innovative distribution strategies to reach customers in rural India and Tanzania, to product development in Cambodia, product assembly in Mozambique and the introduction of ‘pay as you go’ technology in Kenya.

本文主要介绍如何在Wado设计套件中进行时序约束，原文出自 xilinx中文社区。1 Timing Constraints in Vivado-UCF to xdcVivado软件相比于sE的一大转变就是约束文件，5E软件支持的是UcF（User Constraints file，而 Vivado软件转换到了XDc（Xilinx Design Constraints）。XDC主要基于SDc（Synopsys Design Constraints）标准，另外集成了Xinx的一些约束标准可以说这一转变是xinx向业界标准的靠拢。Altera从 TimeQuest开始就一直使用SDc标准，这一改变，相信对于很多工程师来说是好事，两个平台之间的转换会更加容易些。首先看一下业界标准SDc的原文介绍：Synopsys widely-used design constraints format, known as sDc, describes the design intent"and surrounding constraints for synthesis, clocking, timing, power, test and environmental and operating conditions. sDc has been in use and evolving for more than 20 years, making it the most popular and proven format for describing design constraints. Essentially all synthesized designs use SDc and numerous EDa companies have translators that can read and process sDc
