Refrigeration & Air Conditioning Technology Review

Average Reviews:

(More customer reviews)This book is surely one of the best available for its purpose, that is, to give an introduction to the refrigeration and air conditioning technology, and also to teach how to install, service, and maintain all the hardware associated with this.
The text is very well writen, in a very clever language. Graphics are very good, and very helpful to the understanding of topics. Sections dedicated to the electrical and electronic sub-systems were a surprise: they are also very clear, and are very helpful even for experienced technicians. There are even sections dedicated to airflow at conditioned spaces, a matter that isn't very well undestood by technicians.
I strongly suggest this book to the people that wants to start working in this technical area, and also to that who already work with it. Very useful to the begginer and to the experienced technician as well.

Mechanical Vibrations (5th Edition) Review

Average Reviews:

(More customer reviews)I recently used this as a text to teach Vibrations to Mechanical Engineering seniors after Vibration Analysis by Vierck went out of print. I was attracted to Rao's book because much of the presentation is similar to Vierck. After using this text for one semester, I was not satisfied. I was particularly concerned by Chapter 2 where the fundamentals of damped single degree of freedom systems are covered. This Chapter is critical to building the foundation of Vibration Theory and I was disturbed to find that two critical plots, the time history comparison of responses with various damping levels and the phase plane plot for the same cases were seriously incorrect. While errors always can be found in texts, these plots were so obviously wrong at first glance that I wondered how a book with 29 reviewers (as listed in the Acknowledgements) has such glaring errors. As I progressed through the text I found a number of other errors including incorrect equations in some places. I also found that some material, emphasized in Vierck, that I consider important was buried in the worked examples rather than being emphasized as part of the book's text. While the book does present a lot of material and gives some interesting problems, I found that I was not comfortable with the text at the end of the course. I have since decided to drop this book from consideration as our text.

Mechanical Vibrations, 5/e is ideal for undergraduate courses in Vibration Engineering.

Retaining the style of its previous editions, this text presents the theory, computational aspects, and applications of vibrations in as simple a manner as possible. With an emphasis on computer techniques of analysis, it gives expanded explanations of the fundamentals, focusing on physical significance and interpretation that build upon students' previous experience. Each self-contained topic fully explains all concepts and presents the derivations with complete details. Numerous examples and problems illustrate principles and concepts.

Schaum's Outline of Basic Electrical Engineering Review

Average Reviews:

(More customer reviews)I'm presently using this as a textbook in an into-level EE class. The book is a great concept - give a book of problems and enough information on the theory to solve them, including some step-by-step examples. And, sometimes, it works well. What kills it are the repeated glaring errors in the answers it gives for the questions - so far, I'd venture to say that, after the first couple chapters, more then 10% of the answers are wrong, be it from swapping a sign someplace or an outright mistake in understanding on the part of the person who solved the problem. This makes the book uterly and totally unacceptable - it has as much potential to damage someone's knowledge of electronics as to teach the person.
