The serious study of the practice of how to determine the appropriate content of a
specification is a seldom-appreciated pastime. Those who have the responsibility to
design a product would prefer a greater degree of freedom than permitted by the con-
tent of a specification. Many of those who would manage those who would design
a product would prefer to allocate all of the project funding and schedule to what
they consider more productive labor. These are the attitudes, of course, that doom a
project to defeat but they are hard to counter no matter how many times repeated by
design ENGINEERs and managers. A system ENGINEER who has survived a few of these
experiences over a long career may retire and forget the past but we have an endur-
ing obligation to work toward changing these attitudes while trying to offer younger
system ENGINEERs a pathway toward a more sure success in requirements analysis and
specification publishing.
When thinking about mobile radio ENGINEERs there is a tendency to
assume that the ENGINEERing function relates solely to the technical
aspects of the network, such as the equipment design or the network
design. That is certainly a key part of the role of a mobile radio ENGINEER.
However,increasinglyENGINEERsarerequiredtointeractwithprofession-
als from other divisions. The “complete wireless professional” should
know about mobile networks; fixed networks; other types of mobile
systems; regulatory and government policy; the requirements of the
users; and financial, legal, and marketing issues.

Since the original publication of Manual 74 in 1991, and the preceding
“Guidelines for Transmission Line Structural Loading” in 1984, the
understanding of structural loadings on transmission line structures has
broadened signifi cantly. However, improvements in computational capa-
bility have enabled the transmission line ENGINEER to more easily deter-
mine structural loadings without properly understanding the parameters
that affect these loads. Many seasoned professionals have expressed
concern for the apparent lack of recent information on the topic of struc-
tural loadings as new ENGINEERs enter this industry. The Committee on
Electrical Transmission Structures is charged with the responsibility to
report, evaluate, and provide loading requirements of transmission struc-
tures. This task committee was therefore formed to update and revise the
1991 manual.
December 2007, San Jose, California: It seems a long time ago.
I walked into a big networking company to head their small
Power over Ethernet (PoE) applications team. Surprisingly,
I hardly knew anything about PoE prior to that day, having been a
switching-power conversion ENGINEER almost all my life. But it
seemed a great opportunity to widen my horizons. As you can see,
one notable outcome of that seemingly illogical career choice five
years ago is the book you hold in your hands today. I hope this small
body of work goes on to prove worthy of your expectations and also
of all the effort that went into it. Because, behind the scenes, there is a
rather interesting story to relate—about its backdrop, intertwined
with a small slice of modern PoE history, punctuated by a rather res-
tive search for our roots and our true heroes, one that takes us back
almost two centuries
I wrote this book so that students, hobbyists, and ENGINEERs alike can take advantage of the Arduino
platform by creating several projects that will teach them about the ENGINEERing process. I also wanted to
guide the reader through introductory projects so that they could get a firm grasp on the Arduino
Language, and how to incorporate several pieces of hardware to make their own projects.
This book offers so much information on the Arduino, not just the basic LED projects but it
offers different peripherals such as Ultrasonic sensor, the Xbox? controller, Bluetooth, and much more.
This book also teaches the non-ENGINEER to follow a process that will help them in future project (not just
Arduino projects).
This book introduces students to the theory and practice of control systems ENGINEER-
ing. The text emphasizes the practical application of the subject to the analysis and
design of feedback systems.
The study of control systems ENGINEERing is essential for students pursuing
degrees in electrical, mechanical, aerospace, biomedical, or chemical ENGINEERing.
Control systems are found in a broad range of applications within these disciplines,
from aircraft and spacecraft to robots and process control systems.
Control Systems ENGINEERing is an exciting and challenging field and is a
multidisciplinary subject. This book is designed and organized around the concepts of control
systems ENGINEERing using MATLAB, as they have been developed in the frequency and time
domain for an introductory undergraduate or graduate course in control systems for ENGINEER-
ing students of all disciplines.
Despite the development of a now vast body of knowledge known as
modern control theory, and despite some spectacular applications of this
theory to practical situations, it is quite clear that much of the theory has
yet to find application, and many practical control problems have yet to find
a theory which will successfully deal with them. No book of course can
remedy the situation at this time. But the aim of this book is to construct
one of many bridges that are still required for the student and practicing
control ENGINEER between the familiar classical control results and those of
modern control theory.
