By inventing the wireless transmitter or radio in 1897, the Italian physicist Tomaso
Guglielmo Marconi added a new dimension to the world of communications. This
enabled the transmission of the human voice through space without wires. For this
epoch-making invention, this illustrious scientist was honored with the Nobel Prize
for Physics in 1909. Even today, students of wireless or radio technology remember
this distinguished physicist with reverence. A new era began in Radio
Communications.

Rapid progress in information and communications technology (ICT) induces
improved and new telecommunications services and contributes greatly to society
in general and to vendors and network and service providers. In addition to existing
services such as telephony or leased line services, spread of the Internet, the Internet
Protocol (IP) phone, and new communications services like IPTV are making great
progress with the development of digital subscriber lines (DSL) and high - speed
communications technologies like fi ber to the home (FTTH).

Electrostatic discharge (ESD) events can have serious detrimental
effects on the manufacture and performance of microelectronic devices,
the systems that contain them, and the manufacturing facilities used to
produce them. Submicron device technologies, high system operating
speeds, and factory automation are making ESD control programs a
critical factor in the quality and reliability of ESD-sensitive products.

Since its release, Arduino has become more than just a development platform; it has become a culture built around
the idea of open source and open hardware, and one that is reimagining computer science and education. Arduino has
opened hardware development by making the starting skills easy to obtain, but retaining the complexities of real-world
application. This combination makes Arduino a perfect environment for school students, seasoned developers, and
designers. This is the first Arduino book to hold the title of “Pro,” and demonstrates skills and concepts that are used by
developers in a more advanced setting. Going beyond projects, this book provides examples that demonstrate concepts
that can be easily integrated into many different projects and provide inspiration for future ones. The focus of this book
is as a transition from the intermediate to the professional.

Computer science as an academic discipline began in the 1960’s. Emphasis was on
programming languages, compilers, operating systems, and the mathematical theory that
supported these areas. Courses in theoretical computer science covered finite automata,
regular expressions, context-free languages, and computability. In the 1970’s, the study
of algorithms was added as an important component of theory. The emphasis was on
making computers useful. Today, a fundamental change is taking place and the focus is
more on a wealth of applications. There are many reasons for this change. The merging
of computing and communications has played an important role. The enhanced ability
to observe, collect, and store data in the natural sciences, in commerce, and in other
fields calls for a change in our understanding of data and how to handle it in the modern
setting. The emergence of the web and social networks as central aspects of daily life
presents both opportunities and challenges for theory.

General paradigm in solving a computer vision problem is to represent a raw image
using a more informative vector called feature vector and train a classifier on top of
feature vectors collected from training set. From classification perspective, there are
several off-the-shelf methods such as gradient boosting, random forest and support
vector machines that are able to accurately model nonlinear decision boundaries.
Hence, solving a computer vision problem mainly depends on the feature extraction

高清電子書-C++ Primer Plus, 第6版英文版 1438頁Learning C++ is an adventure of discovery, particularly because the language accommodates several programming paradigms, including object-oriented programming,
generic programming, and the traditional procedural programming.The fifth edition of
this book described the language as set forth in the ISO C++ standards, informally
known as C++99 and C++03, or, sometimes as C++99/03. (The 2003 version was
largely a technical correction to the 1999 standard and didn’t add any new features.)
Since then, C++ continues to evolve.As this book is written, the international C++
Standards Committee has just approved a new version of the standard.This standard had
the informal name of C++0x while in development, and now it will be known as
C++11. Most contemporary compilers support C++99/03 quite well, and most of the
examples in this book comply with that standard. But many features of the new standard
already have appeared in some implementations, and this edition of C++ Primer Plus
explores these new features.
C++ Primer Plus discusses the basic C language and presents C++ features, making
this book self-contained. It presents C++ fundamentals and illustrates them with short,
to-the-point programs that are easy to copy and experiment with.You learn about
input/output (I/O), how to make programs perform repetitive tasks and make choices,
the many ways to handle data, and how to use functions.You learn about the many
features C++ has added to C, including the followi

本文主要介紹如何在Wado設計套件中進行時序約束，原文出自 xilinx中文社區。1 Timing Constraints in Vivado-UCF to xdcVivado軟件相比于sE的一大轉變就是約束文件，5E軟件支持的是UcF（User Constraints file，而 Vivado軟件轉換到了XDc（Xilinx Design Constraints）。XDC主要基于SDc（Synopsys Design Constraints）標準，另外集成了Xinx的一些約束標準可以說這一轉變是xinx向業界標準的靠攏。Altera從 TimeQuest開始就一直使用SDc標準，這一改變，相信對于很多工程師來說是好事，兩個平臺之間的轉換會更加容易些。首先看一下業界標準SDc的原文介紹：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
