RFID, the wireless technology that has helped millions of people around the world to protect their property and make their workplaces safer is now in danger of being viewed as a security risk. Ray Stanton examines the love-hate relationship between people and Radio Frequency Identification [RFID] tags and highlights the need for informed debate about the privacy issues the technology raises.

We obtained the energy transport velocity distribution for a three dimensional ideal cloak explicitly. Near the operation frequency, the energy transport velocity has rather peculiar distribution. The velocity along a line joining the origin of the cloak is a constant, while the velocity approaches zero at the inner boundary of the cloak. A ray pointing right into the origin of the cloak will experience abrupt changes of velocities when it impinges on the inner surface of the cloak. This peculiar distribution causes long time delays for beams passing through the ideal cloak within a geometric optics description.

Exploring C++ uses a series of self–directed lessons to divide C++ into bite–sized chunks that you can digest as rapidly as you can swallow them. The book assumes only a basic understanding of fundamental programming concepts (variables, functions, expressions, statements) and requires no prior knowledge of C or any other particular language. It reduces the usually considerable complexity of C++. The included lessons allow you to learn by doing, as a participant of an interactive education session. You’ll master each step in a one sitting before you proceed to the next. Author Ray Lischner has designed questions to promote learning new material. And by responding to questions throughout the text, youll be engaged every step of the way.

I saw the light of the future when I first read Ray Kurzweil’s best-seller book The Singularity Is Near: When Humans Transcend Biology. One cubic inch of nanotube cir- cuitry, once fully developed, would be up to one hundred million times more powerful than the human brain.

This chapter surveys the high temperature and oxygen partial pressure behavior of complex oxide heterostructures as determined by in situ synchrotron X-ray methods. We consider both growth and post-growth behavior, emphasizing the observation of structural and interfacial defects relevant to the size-dependent properties seen in these systems.

近年来，对器件的失效分析已经成为电力电子领域中一个研究热点。本论文基于现代电力电子装置中应用最广的IGBT器件，利用静态测试仪3716，SEM（Scanning Electrom Microscope，扫描电子显微镜）、EDX（Energy Dispersive X-Ray Spectroscopy、能量色散x射线光谱仪）、FIB（Focused lon beam，聚焦高子束）切割、TEM（Thermal Emmision Microscope，高精度热成像分析仪）等多种分析手段对模块应用当中失效的1GBT芯片进行电特性分析、芯片解剖并完成失效分析，并基于相应的失效模式提出了封装改进方案。1，对于栅极失效的情况，本论文先经过电特性测试完成预分析，并利用THEMOS分析出栅极漏电流通路，找到最小点并进行失效原因分析，针对相应原因提出改进方案。2，针对开通与关断瞬态过电流失效，采用研磨、划片等手段进行芯片的解剖。并用SEM与EDX对芯片损伤程度进行评估分析，以文献为参考进行失效原因分析，利用saber仿真进行失效原因验证。3，针对通态过电流失效模式，采用解剖分析来评估损伤情况，探究失效原因，并采用电感钳位电路进行实验验证。4，针对过电压失效模式，采用芯片解剖方式来分析失效点以及失效情况，基于文献归纳并总结出传统失效原因，并通过大量实验得出基于封装的失效原因，最后采用saber仿真加以验证。

1-1单透镜这个例子是学习如何在ZEMAX里键入资料，包括设置系统孔径（System Aperture）、透镜单位（Lens Units）、以及波长范围（Wavelength Range），并且进行优化。你也将使用到光线扇形图（Ray Fan Plots）、弥散斑（Spot Diagrams）以及其它的分析工具来评估系统性能。这例子是一个焦距100mm、F/4的单透镜镜头，材料为BK7，并且使用轴上（On-Axis）的可见光进行分析。首先在运行系统中开启ZEMAX，默认的编辑视窗为透镜资料编辑器（Lens Data Editor，LDE），在LDE可键入大多数的透镜参数，这些设置的参数包括：·表面类型（Surf:Type）如标准球面、非球面、衍射光栅..等·曲率半径（Radius of Curvature）·表面厚度（Thickness）：与下一个表面之间的距离·材料类型（Glass）如玻璃、空气、塑胶.…等：与下一个表面之间的材料
