consulting editors, each an expert in one of the areas of concentration. The names of the consulting editors are listed on the front page of the volume. The areas of concentration are applied mechanics, biomechanics, compu­ tational mechanics, dynamic systems and control, energetics, mechanics of material, processing, thermal science, and tribology. Professor Marshek, the consulting editor for dynamic systems and con­ trol, and I are pleased to present this volume of the series: Mechatronics: Electromechanics and Contromechanics by Professor Denny K. Miu. The selection of this volume underscores again the interest of the Mechanical Engineering Series to provide our readers with topical monographs as well as graduate texts.
