Masters Theses in the Pure and Applied Sciences was first conceived, published, and dis seminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS) * at Purdue University in 1957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemination phases of the ac tivity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all concerned if the printing and distribution of the volume were handled by an international publishing. house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Corporation of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 25 (thesis year 1980) a total of 10,308 theses titles from 27 Canadian and 214 United States universities. We are sure that this broader base for theses titles reported will greatly enhance the value of this important annual reference work. While Volume 25 reports theses submitted in 1980, on occasion, certain universities do report theses submitted in previous years but not reported at the time.

This book contains the research report of the DFG Research Unit FOR 1845 (2014-2020) of the Universities of Bremen and Hannover. The thematic focus lies on speeding up ultra-precision machining technology by following a holistic approach to high-performance cutting. This includes ultra-precision milling at high spindle speeds (>10000 rpm), precision tool setting mechanisms for multi-cutting-edge diamond milling tools, magnetic levitation technology for high velocity feed axes, and dedicated control strategies for error identification and compensation at high speeds. Furthermore, automation and measurement aspects of the machine setup process especially for precision balancing of the spindle rotors are presented. Finally, it is demonstrated that how the developed technologies may be integrated into a common machine tool setup. The target audience primarily comprises research experts and practitioners in production engineering, but the book may also be of interest to graduate students alike.

Ultra-precision bearings can achieve extreme accuracy of rotation, making them ideal for use in numerous applications across a variety of fields, including hard disk drives, roundness measuring machines and optical scanners. Ultraprecision Bearings provides a detailed review of the different types of bearing and their properties, as well as an analysis of the factors that influence motion error, stiffness and damping. Following an introduction to basic principles of motion error, each chapter of the book is then devoted to the basic principles and properties of a specific type of bearing: ball, hydrodynamic, aerodynamic, hydrostatic and aerostatic. The book concludes with a comparison of these types of bearing and their applications.
