There are many people who work to put a book together, and although as authors we dedicate an enormous amount of time to writing the book, it would never be published without the dedicated, hard work of the whole team at Wiley. They are truly a fantastic group to work with, and without the Wiley team this book would have never been possible.

First, wed like to thank Kenyon Brown, our senior acquisitions editor, who offered us support and guidance through the writing process. Ken was always there to answer questions and point us in the right direction. Without Ken as a mentor, we could never have pulled this one off.

We also can never thank our development editor David Clark too many times; David is a true professional who stayed on top of the schedule and professionally reminded us of the next upcoming deadline we were working to meet. Without Davids help putting this book together, it would have been much more difficult than it was. David has the ability to take the raw text from the authors, who are primarily engineers, and manage to turn it into presentable copy. Thanks again, David!

Jon Buhagiar offered excellent input as our technical editor. He gave us invaluable feedback on how to make the technical concepts more understandable to the readers and pointed out where we needed to modify our technical content for accuracy. It was great that Jon was able to be on this project with us.

A big thank-you to Katie Wisor, the production editor for this book. Kim Wimpsett worked her markup magic in the background as the copy editor. The authors are both amazed at how Katie and Kim along with their team of professionals could take our work and transform it into such a presentable book. Were sure there is a whole staff at Wiley lurking in the background, and we will never know how much they helped, but to everyone at Wiley, a big thank-you! You made the late nights and long weekends of writing and putting this book together all worthwhile.
