I want to thank my wonderful family for all the support, specifically, my husband, Marko, and my two amazing sons, Patrik and Matias. Without your support I could have not written this book.

A very special thank-you to Philip Stoyanov and C. J. Date for all your valuable advice and support! And of course thank you to the two best technical editors in the world: Jeff Smith and Kent Graziano. I want to thank professor emeritus Seppo Sippu from University of Helsinki ...
