D(X) Centres and other Metastable Defects in Semiconductors, Proceedings of the INT Symposium, Mauterndorf, Austria, 18-22 February 1991
by W Jantsch; R A StradlingSince the first reports on metastable defects in III-V and II-VI compound semiconductors appeared in the late 1960s, the number of reports on defects with metastable states has been growing at an ever increasing rate. D(X)-center and other metastability defects cause many technical problems that are exacerbated by the uncertainty and controversy surrounding the mechanisms that cause them. A lively mix of theoretical and experimental discussions, D(X)-Centres and other Metastable Defects in Semiconductors presents a timely investigation of these systems. The book discusses topics such as, the validity of negative or positive U models, as well as alternative views that challenge existing ideas. The richness and precision of experimental data now emerging in the field is chronicled as are new investigative techniques. Based on an INT symposium, this book provides a successful forum where an extraordinary variety of ideas, including new perspectives, are examined critically.
D-Day Landing Craft: How 4,126 ‘Ugly and Unorthodox’ Allied Craft made the Normandy Landings Possible
by Andrew WhitmarshThe contribution of landing craft and their crews to the 1944 Normandy campaign was enormous, and often overlooked. Most of the more than 132,000 Allied troops who landed on the beaches on D-Day came ashore from landing craft. The book examines why so many different types of landing craft were used in the operation; how they were built in both the UK and North America, over several years and with many competing war production requirements and operational needs. In the lead up to D-Day the Allies never seemed to have enough landing craft, their availability and production regularly discussed by top Allied leaders. This account is essential to anyone who wants to fully understand the course of D-Day, and the nature of Allied preparations for the campaign.

DC Power Supplies: Power Management and Surge Protection for Power Electronic Systems
by Nihal KularatnaAs we increasingly use electronic devices to direct our daily lives, so grows our dependence on reliable energy sources to power them. Because modern electronic systems demand steady, efficient, reliable DC voltage sources—often at a sub-1V level—commercial AC lines, batteries, and other common resources no longer suffice. New technologies also require intricate techniques to protect against natural and manmade disasters. Still, despite its importance, practical information on this critical subject remains hard to find. Using simple, accessible language to balance coverage of theoretical and practical aspects, DC Power Supplies, Power Management and Surge Protection details the essentials of power electronics circuits applicable to low-power systems, including modern portable devices. A summary of underlying principles and essential design points, it compares academic research and industry publications and reviews DC power supply fundamentals, including linear and low-dropout regulators. Content also addresses common switching regulator topologies, exploring resonant conversion approaches. Coverage includes other important topics such as: Control aspects and control theory Digital control and control ICs used in switching regulators Power management and energy efficiency Overall power conversion stage and basic protection strategies for higher reliability Battery management and comparison of battery chemistries and charge/discharge management Surge and transient protection of circuits designed with modern semiconductors based on submicron dimension transistors This specialized design resource explores applicable fundamental elements of power sources, with numerous cited references and discussion of commercial components and manufacturers. Regardless of their previous experience level, this information will greatly aid designers, researchers, and academics who, study, design, and produce the viable new power sources needed to propel our modern electronic world.

DC-DC Converter Topologies: Basic to Advanced (IEEE Press)
by Gerry MoschopoulosDC-DC Converter Topologies A comprehensive look at DC-DC converters and advanced power converter topologies for all skills levels As it can be rare for source voltage to meet the requirements of a Direct Current (DC) load, DC-DC converters are essential to access service. DC-DC power converters employ power semiconductor devices (like MOSFETs and IGBTs) as switches and passive elements such as capacitors, inductors, and transformers to alter the voltage provided by a DC source into the necessary DC voltage as is required by a DC load. This source can be a battery, solar panels, fuel cells, or a DC bus voltage fed by rectified AC utility voltage. As the many components of DC-DC converters can be differently arranged into circuit structures called topologies, there are as many possible circuit topologies as there are possible combinations of circuit elements. Focusing on DC-DC switch-mode power converters ranging from 50 W to 10kW, DC-DC Converter Topologies provides a survey of all converter topology types within this power range. General principles are described for each topology type using a representative converter as an example. Variations that can be found that differ from the example are then examined, with a helpful discussion of comparisons when relevant. A broad range of topics is covered within the book, from simple, low-power converters to complex, high-power converters and everywhere in between. DC-DC Converter Topologies readers will also find: A detailed discussion of four key DC-DC converter topologies Description of isolated two-switch pulse-width modulated (PWM) topologies including push-pull, half-bridge, and interleaved converters An exploration of high-gain converters such as coupled inductors, voltage multipliers, and switched capacitor converters This book provides the tools so that a non-expert will be equipped to deal with the vast array of DC-DC converters that presently exist. As such, DC-DC Converter Topologies is a useful reference for electrical engineers, professors, and graduate students studying in the field.

DECADAL SURVEY OF CIVIL AERONAUTICS: Foundation for the Future
by National Research Council of the National AcademiesThe U.S. air transportation system is very important for our economic well-being and national security. The nation is also the global leader in civil and military aeronautics, a position that needs to be maintained to help assure a strong future for the domestic and international air transportation system. Strong action is needed, however, to ensure that leadership role continues. To that end, the Congress and NASA requested the NRC to undertake a decadal survey of civil aeronautics research and technology (R&T) priorities that would help NASA fulfill its responsibility to preserve U.S. leadership in aeronautics technology. This report presents a set of strategic objectives for the next decade of R&T. It provides a set of high-priority R&T challenges—-characterized by five common themes—-for both NASA and non-NASA researchers, and an analysis of key barriers that must be overcome to reach the strategic objectives. The report also notes the importance of synergies between civil aeronautics R&T objectives and those of national security.
DECREASING ENERGY INTENSITY IN MANUFACTURING: Assessing the Strategies and Future Directions of the Industrial Technologies Program
by National Research Council of the National AcademiesThe U.S. Department of Energy (DOE) has supported the Industrial Technologies Program (ITP) for more than a decade. This program supports R&D into energy efficiency technologies designed to decrease the energy intensity of the U.S. industrial sector. The focus in on seven energy-intensive industries—aluminum, chemicals, forest products, glass, metal casting, mining, and steel—known as the Industries of the Future (IOF). DOE asked the NRC for a review of this program including an evaluation of the ITP strategic plan, an evaluation of the technical quality of individual subprogram plans, and the prospective value of the multi-year program plan. This report presents the results of that review. It contains an assessment of the ITP strategy, of how effective it is being implemented, and the likelihood of achieving program goals. It also provides conclusions about the quality of the subprograms and recommendations about how to strengthen the subprograms and the overall program.
