One of the predominant Topics in the domain of the emerging Smart Grid can be
seen in standardization. With the combination of existing protection and automa-
tion technology with upcoming ICT-based solutions, different interoperability is-
sues arise when technologies have to be combined in the infrastructure. Standards
have proven to be one of the most striking solutions to actually cope with this Topic.
Since 2008, this Topic has gained much attention in various political and technical
agendas.

RFID Applied is just that. It’s about the application of RFID. If you want a
book about electrical and computer engineering you need another source.
Let’s say that you have been asked to lead an effort at your company to
use RFID in your supply chain. You have heard about RFID because so
much has been written on the Topic since Wal-Mart and the US DoD made
their proclamations that shippers attach RFID tags to their deliveries. This
book is for you!

In the first chapter, the Topic of this book is classified into the area of pervasive com-
puting. Further, security and privacy in the scope of RFID technology is motivated
and the vision that guides the remainder of this book is introduced.

In this new edition of the book, only minor changes were made to the original
nine chapters but three new chapters treat Topics of increasing interest to GPS
users and equipment developers. One Topic, improving the GPS receiver sensi-
tivity may extend their operations into buildings, which is becoming important
for emergency rescue and urban warfare.

This book is either ambitious, brave, or reckless approaching
a Topic as rapidly evolving as industrial control system (ICS)
security. From the advent of ICS-targeted malicious software
such as Stuxnet to the advanced persistent threats posed by
organized crime and state-sponsored entities, ICS is in the
crosshairs and practices and controls considered safe today
may be obsolete tomorrow. Possibly more so than in more
traditional IT security, because of the differences inherent in
ICS.

This book describes a unifying framework to networked teleoperation systems
cutting across multiple research fields including networked control system for linear
and nonlinear forms, bilateral teleoperation, trilateral teleoperation, multilateral
teleoperation, cooperative teleoperation, and some teleoperation application
examples. Networked control has been deeply studied at the intersection of systems
& control and robotics for a long time, and many scholarly books on the Topic have
been already published. Nevertheless, the approach remains active even in several
new research fields, such as bilateral teleoperation, single master and multiple
slaves, trilateral teleoperation, and multilateral teleoperation

The basic Topic of this book is solving problems from system and control theory using
convex optimization. We show that a wide variety of problems arising in system
and control theory can be reduced to a handful of standard convex and quasiconvex
optimization problems that involve matrix inequalities. For a few special cases there
are “analytic solutions” to these problems, but our main point is that they can be
solved numerically in all cases. These standard problems can be solved in polynomial-
time (by, e.g., the ellipsoid algorithm of Shor, Nemirovskii, and Yudin), and so are
tractable, at least in a theoretical sense. Recently developed interior-point methods
for these standard problems have been found to be extremely efficient in practice.
Therefore, we consider the original problems from system and control theory as solved.

This book will discuss the Topic of Control Systems, which is an interdisciplinary engineering
Topic. Methods considered here will consist of both "Classical" control methods, and
"Modern" control methods. Also, discretely sampled systems (digital/computer systems) will
be considered in parallel with the more common analog methods. This book will not focus
on any single engineering discipline (electrical, mechanical, chemical, etc.), although readers
should have a solid foundation in the fundamentals of at least one discipline.

電學(xué)中的測量技術(shù)涉及范圍非常廣,電流測量在電學(xué)計量中占有非常重要的位置。如何精確地進行電流測量是精密測量的一大難題。傳統(tǒng)的電流檢測電路多采用運算放大芯片與片外電流檢測電路相結(jié)合的方式,電路集成度很低,需要較多的接口和資源才能完成對電路的檢測。本文把所有電路部分都集成在一塊芯片上,包括檢測電阻,運算放大器電路及模擬轉(zhuǎn)數(shù)字轉(zhuǎn)換電路,從而在電路內(nèi)部可以進行電流檢測,使電路更好的集成化。前置電路使用二級共源共柵結(jié)構(gòu)的運算放大器,減小溝道長度調(diào)制效應(yīng)造成的電流誤差。10位SAR ADC中采用電容驅(qū)動能力強的傳輸門保證了模數(shù)轉(zhuǎn)化器的有效精度。比較器模塊采用再生鎖存器與遲滯比較器作為基礎(chǔ)單元組合解決精密測量的問題。本設(shè)計可以作為嵌入芯片內(nèi)的一小部分而檢測芯片中的微小電流1mA~100mA,工作電壓在1.8v左右,電流檢測精度預(yù)期達到10uA的需求。The measurement technology in electricity involves a wide range,and current measurement plays a very important position in electrical measurement.How to accurately measure current is a big problem in precision measurement. The traditional current detecting circuit adopts the combination of the operational amplifier chip and theoff-chip current detecting circuit, The circuit integration is very low, and more interfaces and resources are needed tocomplete the circuit detection.This Topic integrates all the circuit parts into one chip, including detection resistance, operational amplifier circuit andanalog to digital conversion circuit. Highly integrated circuit makes the external resources on the chip more intensive,so that current detection can be carried out inside the circuit, so that the circuit can be better integrated. Thefront-end circuit of this project uses two-stage cascade operational amplifier and cascade tube to reduce the currenterror caused by channel length modulation effect. In 10-bit SAR ADC, the transmission gate with strong capacitivedriving ability ensures the effective accuracy of the analog-to-digital converter. Comparator module uses regenerativelatch and hysteresis comparator as basic unit to solve the difficult problem of precision measurement. This Topic can beused as a small part of the embedded chip to detect the micro-current in the chip 1 mA~100 mA, the working voltageis about 1.8v, and the current detection accuracy is expected to reach the requirement of 10 uA.
