Although they are some of the main components in the design of power electronic converters, the design of inductors and transformers is often still a trial-and-error process due to a long working-in time for these components. Inductors and Transformers for Power Electronics takes the guesswork out of the design and testing of these systems and provides a broad overview of all aspects of design.

There’s a big secret at Dr. Hugo’s Factory for Making Robots. When the inventors aren’t looking, their tiny robots go on big adventures! It all starts when Zander - possibly the world’s most absent-minded inventor - trips over a metal box buried outside the factory. When no-one can figure out how to open it, the robots sneak out and try it for themselves in Puzzle Bots, a fun and exciting Puzzle game.

During the last few years, the field of nonlinear problems has undergone great development. This book consisting of the updated Grundlehren volume 252 by the author and of a newly written part, deals with some important geometric problems that are of interest to many mathematicians and scientists but have only recently been partially solved. Each problem is explained, up-to-date results are given and proofs are presented. Thus, the reader is given access, for each specific problem, to its present status of solution as well as to the most up-to-date methods for approaching it. The main objective of the book is to explain some methods and new techniques, and to apply them. It deals with such important subjects as variational methods, the continuity method, parabolic equations on fiber.
