I can remember buying my first electronic calculator. I was teaching a graduate level statistics course and I
had to have a calculator with a square root function. Back in the late 1960s, that was a pretty high-end
requirement for a calculator. I managed to purchase one at the “educational discount price” of $149.95!
Now, I look down at my desk at an ATmega2560 that is half the size for less than a quarter of the cost and
think of all the possibilities built into that piece of hardware. I am amazed by what has happened to
everything from toasters to car engines. Who-da-thunk-it 40 years ago?

This book is an outgrowth of a course developed at Stanford University over
the past five years. It is suitable as a self-contained textbook for second-level
undergraduates or for first-level graduate students in almost every field that
employs quantitative methods. As prerequisites, it is assumed that the student
may have had a first course in differential equations and a first course in linear
algebra or matrix analysis. These two subjects, however, are reviewed in
Chapters 2 and 3, insofar as they are required for later developments.

The idea of writing this book arose from the need to investigate the main principles of
modern power electronic control strategies, using fuzzy logic and neural networks, for
research and teaching. Primarily, the book aims to be a quick learning guide for
postgraduate/undergraduate students or design engineers interested in learning the
fundamentals of modern control of drives and power systems in conjunction with the
powerful design methodology based on VHDL.

The large-scale deployment of the smart grid (SG) paradigm could play a strategic role in
supporting the evolution of conventional electrical grids toward active, flexible and self-
healing web energy networks composed of distributed and cooperative energy resources.
From a conceptual point of view, the SG is the convergence of information and
operational technologies applied to the electric grid, providing sustainable options to
customers and improved security. Advances in research on SGs could increase the
efficiency of modern electrical power systems by: (i) supporting the massive penetration
of small-scale distributed and dispersed generators; (ii) facilitating the integration of
pervasive synchronized metering systems; (iii) improving the interaction and cooperation
between the network components; and (iv) allowing the wider deployment of self-healing
and proactive control/protection paradigms.

The goal of this textbook is to support the teaching of digital and statistical signal
processing in higher education. Particular attention is paid to the presentation of the fun-
damental theory; key topics are outlined in a comprehensible way, and all areas of the
subject are discussed in a fashion that aims at simplification without sacrificing accuracy.

HRVAS is a complete and self-contained heart rate variability analysis software (HRVAS) package. HRVAS offers several preprocessing options. HRVAS offers time-domeain, freq-domain, time-frequency, and nonlinear HRV analysis. All results can be exported to an Excel file. For processing many files HRVAS offers a bach processing feature. All settings/options can be saved to a .mat file and reloaded for future HRV analysis. Upon starting HRVAS all previously used settings/options are loaded.

可測試性設計（Design-For-Testability，DFT）已經成為芯片設計中不可或缺的重要組成部分。它通過在芯片的邏輯設計中加入測試邏輯提高芯片的可測試性。在高性能通用 CPU 的設計中，可測試性設計技術得到了廣泛的應用。本文結合幾款流行的 CPU，綜述了可應用于通用 CPU 等高性能芯片設計中的各種可測試性方法，包括掃描設計（Scan Design），內建自測試（Built-In Self-Test，BIST），測試點插入（Test Point Insertion），與 IEEE 1149.1標準兼容的邊界掃描設計（Boundary Scan Design，BSD）等技術。

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

本系統采用電動機電樞供電回路串接采樣電阻的方式來實現對小型直流有刷電動機的轉速測量。該系統主要由二階低通濾波電路,小信號放大電路、單片機測量顯示電路、開關穩壓電源電路等組成。同時自制電機測速裝置,用高頻磁環作為載體,用線圈繞制磁環,利用電磁感應原理檢測電機運行時的漏磁,將變化的磁場信號轉化為磁環上的感應電流。用信號處理單元電路將微弱電信號轉化為脈沖信號,送由單片機檢測,從而達到準確測量電機的速度的要求。In this system, the sampling resistance of armature power supply circuit is connected in series to measure the speed of small DC brush motor. The system is mainly composed of second-order low-pass filter circuit, small signal amplifier circuit, single-chip measurement and display circuit, switching regulated power supply circuit and so on. At the same time, the self-made motor speed measuring device uses high frequency magnetic ring as the carrier, coil winding magnetic ring, and electromagnetic induction principle to detect the leakage of magnetic field during the operation of the motor, which converts the changed magnetic field signal into the induced current on the magnetic ring. The weak electric signal is transformed into pulse signal by signal processing unit circuit, which is sent to single chip computer for detection, so as to meet the requirement of accurate measurement of motor speed.
