Tables are just scanned from printed version and unreadable
I tried the preview on the Kindle for iPad app, and it was barely useable at best. The tables were just scanned from the printed version, in a resolution that rendered the tables unusable when enlarged to be readable.The few graphics I saw were OK though.

Note to Amazon.com: turn up the resolution when scanning images from the printed version for use in the Kindle version.A table that is enlarged so the text is of readable size ness to be, well, readable.

Didn't find helpful for PE review
After having the book for over a couple weeks and not using it for a single reason while studying for the POWER PE, I've decided to return it. It's not worth $130 in my mind. Sure, it has some good stuff in it, but that's a lot of money for a book that I may never use again. I honestly don't think it would help during the test, and if I'm at home or at work I can easily find better information in a different reference book or online. I should also note, I TRIED, MANY TIMES to use it to look up topics while studying but it was completely useless, in my opinion. I'm sure somebody can find it useful, but not I. Hope this helps you out.

Product Description
The theory of probability is a powerful tool that helps electrical and computer engineers to explain, model, analyze, and design the technology they develop. The text begins at the advanced undergraduate level, assuming only a modest knowledge of probability, and progresses through more complex topics mastered at graduate level. The first five chapters cover the basics of probability and both discrete and continuous random variables. The later chapters have a more specialized coverage, including random vectors, Gaussian random vectors, random processes, Markov Chains, and convergence. Describing tools and results that are used extensively in the field, this is more than a textbook; it is also a reference for researchers working in communications, signal processing, and computer network traffic analysis. With over 300 worked examples, some 800 homework problems, and sections for exam preparation, this is an essential companion for advanced undergraduate and graduate students. Further resources for this title, including solutions (for instructors only), are available online at www.cambridge.org/9780521864701. ... Read more

Quick delivery
I'm surprised that the delivery to New Zealand is very quick, even quicker then the projected date that has been made by Amazon in advance.

good book
I used this book for a EE Probability course, and the professor is a freak Korean guy....

an excellent book to begin probability
This is an excellent book on probability. What I liked about it is the fact that it is sprinkled with numeours examples. The language the author has used is also easy to understand but at the same time, formal. It really strikes the balance.

However, I think there should be more explanation of combinatorics in ch2. But if a person has had some prior knowledge of probability, they should refer to some other book for that portion.

well suited for a university course
Gubner provides an excellent text for undergrads or grads wanting a solid background in applying the ideas of probability and random processes. The emphasis is on applications in electrical engineering. The book presupposes a solid background in calculus and some circuit theory. Ideally, the student might be a third year undergrad or higher.

The main ideas in probability are developed. Getting to the Central Limit Theorem and the Gaussian (bell) curve. The probability distributions most useful to you might be the continuous ones.

Then, the text develops the ideas of random processes. When these can be assumed to be stationary, then it makes tractable vast areas of applications, as in the communications theory of the signal to noise ratio of a channel.

The book shines as a text for a university course because of the wealth of examples and problem sets. The difficult of the latter varies considerably, which is also another advantage to a lecturer facing students with a range of abilities. ... Read more

Product Description
The first edition of this title proved the most successful of the Portable Handbook series launched in 1999. Aimed at electrical engineers and technicians working in building power systems, the relentlessly practical Handbook succeeded as an in the field working tool. This new edition is necessitated by the new 2002 version of the National Electrical Code (NEC). This code changes render much of the existing material obsolete, so over half the chapters require heavy rewrites to stay current. ... Read more

Great Resource
Great field resource for engineers, based on the NEC. Great section on control wiring schematics.

Well, It IS Portable
This is a good collection of useful information in compact form. I like the old tables that are missing in newer editions of the NEC. When odering this book, be sure to get a good magnifying glass. Lots of 3 pt text here.

Perhaps an excellent book on the subject, but as far as an "introduction" goes...
First, I suppose I should mention that I am a student, and not a lecturer. Next, I'll sum up my opinion of this book by saying that it is a terrible stand-alone way of attempting to learn the material.

My largest concern with the text is that, past the cover of the book, it makes no attempt to be an introduction to anything. My main gripe in this respect is that the author doesn't attempt to explain the notation, beyond a very brief review here and there. A review of what, exactly, I'm not entirely sure. This wouldn't present a huge obstacle if one had a competent professor, but in my situation I was stuck with a lecturer who felt the book was good enough to teach directly, and I mean directly, from. Considering the huge dearth of examples in the text, this can create a massive problem for students that are actually new to the material.

Which prompts my next issue with the book. There are next to no examples for many of the sections. Many sections contain one example, which is useless and inapplicable to the homework problems and quiz problems (Which are all useless and inapplicable themselves without a solutions manual, especially when your professor doesn't take the time to go over them). -A quick aside here, I should note that this review is biased due to my experience with an inept professor. When the class regularly lets out half an hour early, there's no excuse not to take the time to go back over the homework, since the TA's don't. With that in mind, with a decent lecturer, many of the problems with this text could be easily overcome- Why there aren't at least some solutions, or solutions for the quiz problems, is beyond me, as it would really aid understanding to see how one or two actual problems are worked, instead of just showing a graph and calling it an example.

To sum it up, this book is incredibly frustrating.

How is this getting good reviews?
So from a student that actually is using this book, this is terrible. Very few examples, skimming over content, and no answers! WHAT GOOD IS THIS BOOK IF YOU ONLY USE IT TO GET YOUR HOMEWORK PROBLEMS FROM THE CLASS?! I've learned more from searching wikipedia on the subject than reading this book. Maybe schools should choose books based on their content and their help to students rather than some sort of corporate money game with the book companies. I could only imagine those are the people giving this book a good review, or they have never even cracked it open and tried to learn probability for their first time from it. Thank you for teaching me nothing and wasting my time.

Very Well-written Book
The text was very plain and the author actually makes it a point to expalin most of the symbols and notation.The book is written from a practcial, not theoretical, perspective although the theory is represented via proofs.Reads easily, but the examples are priceless.

Relatively good
Although the examples are good, theorems, properties, and so on, are nicely organized and highlighted, there are no solutions for problems.

It is not just this book, but I'm really tired of spending hours upon hours doing questions for which I will have no idea if I completed them correctly. I like to do homework to identify and fill the gaps in my knowledge, not to do best guesses and merely hope that I will eventually get the solutions against which to compare my answers. By then, the exam (or quiz) is already right around the bend and new material is already being covered.

Not so much...
Hardly a "friendly" and "introductory" text. The language, examples and feel of this book are more suited for someone with prior training in this subject. For the student facing the unfortunate situation of having to learn with this text it may be better to get another book and learn the material from it rather than waste a large amount of time with this one. For folks who already understand the subject I'm sure it's quite good. ... Read more

Product Description
This third edition of the principal text on the finite element method for electrical engineers and electronics specialists presents the method in a mathematically undemanding style, accessible to undergraduates who may be encountering it for the first time. Like the earlier editions, it begins by deriving finite elements for the simplest familiar potential fields, and then formulates finite elements for a wide range of applied electromagnetics problems. These include wave propagation, diffusion, and static fields; open-boundary problems and nonlinear materials; axisymmetric, planar and fully three-dimensional geometries; and scalar and vector fields. A wide selection of demonstration programs allows the reader to follow the practical use of the methods. Besides providing all that is needed for the beginning undergraduate student, this textbook is also a valuable reference text for professional engineers and research students. ... Read more

Hard and Heavy but good
I think that the authors don't fill in their matrices or prove some of the results may be my worst fault for this book.
The book is well written and contains most of the formulas and Fortran program you need to do this kind of analysis.
I would have like more complex plane triangles and some more higher dimensional "triangulations".
But the text has been an eye opener for me and I have a lot of study to get the results where I can really understand them.
This text is not an easy one, but the subject even over simplified would still be a very hard one. I think this is an advanced graduate text
and would give most undergrads outside of MIT nightmares.

Product Description
The object of this book is to quickly teach an electrical engineer or technologist how to use Mathcad. Mathcad simultaneously solves and documents calculations. It is oriented toward non-programmers who need to solve numerical engineering problems. Users like Mathcad because its programs follow the natural format of manual calculations. Complete keystroke-to-keystroke details are provided for problem solution and documentation. The reader learns by example. As a calculating tool, Mathcad solves equations. The equations are entered into Mathcad in a format similar to that used in manual calculations. It will solve mesh equations with real or complex numbers and will solve differential equations. Outputs can be numerical or graphical. Mathcad will also do symbolic calculations, meaning that it can reduce complex systems of equations to simpler equations. Documenting calculations is a major reason that Mathcad is used in modern industry. Calculations that in the past might have been recorded in notebooks, or even on easily lost scraps of paper, are now done with Mathcad to take advantage of the accuracy, neatness, traceability, and standardization it provides. Mathcad is available in a free 30 day demonstration version. The key features of Mathcad can be learned in 30 days. ... Read more

Good book, but many math errors.
I would have given this book more stars but there are numerous typos in the equations which definitely challenges one to figure out what the author is talking about.For example, in chapter 3, page 41, the author attempts to show us how to add polynomials with the following example:

(3x(3) + 5x - 4) + (2x(4) + 7x(2) + 9) = 5x(3) + 7x(2) + 5x + 5.

(The single numbers in parentheses are exponents)

Now, 3x(3) cannot be added to 2x(4) with the result of 5x(3).Clearly the author means 2x(3) and not 2x(4), but I have not been able to find an errata sheet or list of corrections for the book online.If this was an isolated typo I wouldn't complain but I am only on chapter 3 and I have found at least 3 such errors in equations.For someone trying to learn the material it is disconcerting to say the least.Again,I do like the book as it speaks in normal language and is a good primer.Its just a shame it has so many non-trivial equation errors.

Short, gentle, "no frills" introduction to engineering math, focused on using mathematics, excludes proofs
Noting all four previous reviewers, in the years since their 2003/4 postings have only reviewed Fripp books, by way of full disclosure let me say I have no family, professional, or personal relationship with the authors. [Smile.]

This is a good refresher or review book for engineering math, targeting engineers rather than mathematicians. The book provides concepts, rules, and examples but no theorems or proofs.The authors clearly have an affection for mathematics and this comes through in the text. They speak to readers in an easy-going conversational, rather than theoretical, tone.

Upon completion readers should feel reasonably "at ease" with the use of key techniques in engineering mathematics, including trigonometry, calculus (differential, integral, and vector), differential equations, and probability and statistic. The text also discusses, very briefly: matrices, finite difference methods, concepts from operations research (e.g., Monte Carlo simulation, gradient descent optimization), finite element techniques, and chaos. Although the latter methods are discussed more for recognition than use.

The book has some minor issues. For example, occasionally less common mathematical representations are used, as when complex numbers are written as a+ib rather than the more common a+bi. The book starts at a level, i.e., basic arithmetic, that the majority of the target audience should probably already be comfortable with. Had this introductory section been dropped, the extra pages could have more appropriately been devoted to expanded coverage of any one or more additional topics from linear algebra, Laplace and Fourier transforms, or hyperbolic functions.

Because of its relatively smaller size and weight, compared to most engineering mathematics texts, the book is easier to hold and use. The smaller size also means the authors had to select those topics they felt most important and leave out many others, as a consequence the book contains less mathematics than found in a full-size text.However, by leaving out proofs, theorems, lemmas etc. there was room to include most of engineering mathematics' core concepts and techniques.

The book is printed on acid-free paper and so can serve as a reference for many years, without the paper degradation (browning) often found in other paperbacks. Overall, this is a solid introduction to the core mathematical skills necessary to solve basic engineering problems. Coverage stops short of topics normally found in advanced engineering mathematics, but the material presented here should allow readers to comfortably continue into advanced topics if desired.

Just Time Well Spent
This book strikes a nice balance - it is a useful reference book, while remaining interesting and entertaining.It takes a practical and innovative approach to addressing the usually stiff topic of math.I can't recall another math book I would characterize as "fun" - and you know how engineers could use more fun in our lives!!!It is an excellent refresher on math topics, and an enjoyable read.The included CD-ROM is a nice bonus.

An Entertaining Math Book
If ever there was a math book that was entertaining, this is it!The authors manage to cram an amazing amount of mathematics into a book that is modest in size compared to the typical engineering math text, yet keep it easy to read. Each section starts with a clear exposition of the relevent concepts then the usefulness of the topic is illustrated with real life practical applications ranging from simple (falling cannon ball) to complex (fluid flow).The accompanying CD provides example problems for the reader to solve.

A good reference for basic engineering math
This book gives a well-selected precis of the basic math needed for the first two years of enginnering but with enough explanations, examples, and short derivations that the reader can actually make some sense of the results.This should be a much better overview that standard references.Its clearly written and very readable.

An "Engineering" Text Without a Home
This could be a very useful book if it:

1. Had answers to at least selected problems (its usefulness as an independent text is rather curtailed by a junior engineer's ability to check his understanding)

2. More attention to actual engineering details (e.g. p31 bottom states,"There is little point to having a mathematical simulation that is accurate to 100 decimal places if the best display or plotting equipment is only accurate to +- 1%.")First, the rounding should be done at the END of the simulation not IN it if the limitation is in the display; second, 100 decimal places versus +- 1% is a careless confusion of units, not to mention the ambiguity of 1% in a display (to what scale or register length?).

I suppose it might be used as a text for an undergraduate or graduate course somewhere, but more likely it would be purchased by an engineer or scientist interested in modeling, and here the lack of answers is a real deficiency.

The demands of the book are small for a senior level electrical engineering course, and not severe for someone with a decent grounding in discrete and continuous mathematics including orthogonal transforms, linear algebra, calculus of several variables, and an introductory probability course.

There are several very good examples of models included, especially the TLM which makes the book worth the rather high price. (I say that as someone with degrees in electrical engineering and many, many hours of post graduate study in mathematics---thus, it may demand a little more of the readerthan I perceive) ...

Suitable for beginners.
I found this book to be an excellent primer to the topic.Finally, a book that will hold your hand through some of the "fundementals."

I would strongly recommend this book for any non eletrical engineer wanting to understand this material.

Really close to a "must have" for the engineering library
Say what you will, but even the EMC/EMI "guru type" person gets confused once in awhile on the complexities of electromagnetics. So that leaves us "little people" in need of a handy, precise and basic-to-advanced "explainer" to get us back on track. I'm fairly seasoned on EMC but I really like this book and carry it with me quite often on trips for handy reference. It certainly provides for the "big picture" while still adding significant depth. Especially for the beginner to intermediate this book is highly recommended. I have this suspicion the advanced persons don't have it far away either! Congratulations to the author. Perhaps he will follow up with an advanced version on select topics.

An easy to read book , so?
The author has succeeded in writing an easy to read book.I read through it in two days.But is it useful and worthy keeping?The author covers a lot of ground, even included a cursory introduction to special relativity and quantum electrodynamics which have no relevance to the rest of the book.It gives a relatively painless introduction to various concepts in electromagnetism.But the superficiality makes it a book for the popular audience rather than electrical engineers.The author does have the good sense to include a set of good references.So read the book once, and study the reference books.The book is not worthy keeping.I've sold mine.

Nice integration of diverse topics
I'd characterize this book as qualitative rather than quantitative.It provides good verbal descriptions for a wide variety of concepts related to electromagnetics.For me, it tied together a lot of lose ends.This book works pretty well for someone who has a moderate grasp of the electromagnetic fundamentals and wants to go to the next level of understanding without becoming mired in equations -- maybe a sort of heavy duty tutorial for students, recent graduates, and just-plain-curious technically oriented people.This is one of those must-read books, but I would not recommend it to someone without knowldge of college-level physics and differential calculus. ...
