The concepts in this book will provide a comprehensive overview of the current state for a broad range of nitride semiconductor devices, as well as a detailed introduction to selected materials and processing issues of general relevance for these applications. This compilation is very timely given the level of interest and the current stage of research in nitride semiconductor materials and device applications. This volume consists of chapters written by a number of leading researchers in nitride materials and device technology addressing Ohmic and Schottky contacts, AIGalnN multiple quantum well laser diodes, nitride vertical cavity emitting lasers, and ultraviolet photodetectors. This unique volume provides a comprehensive review and introduction to application and devices based on GaN and related compounds for newcomers to the field and stimulus to further advances for experienced researchers.

Mechanical Vibration and Shock Analysis, Second Edition Volume 2: Mechanical Shock This volume considers the shock response spectrum, its various definitions, its properties, and the assumptions involved in its calculation. In developing the practical application of these concepts, the shock shapes or profiles most often used in test facilities are presented, together with their characteristics and indications of how to establish test configurations comparable with those of the real-world, measured environment. Following this analysis there is a case study of how to meet these specifications using standard laboratory equipment, shock machines, electrodynamic exciters driven by a time signal or a response spectrum. Discussion of the limitations, advantages and disadvantages of each method is presented. The Mechanical Vibration and Shock Analysis five-volume series has been written with both the professional engineer and the academic in mind. Christian Lalanne explores every aspect of vibration and shock, two fundamental and extremely significant areas of mechanical engineering, from both a theoretical and practical point of view. The five volumes cover all the necessary issues in this area of mechanical engineering. The theoretical analyses are placed in the context of both the real world and the laboratory, which is essential for the development of specifications.

This book fills a unique position in the literature as a dedicated mechanical shock analysis book. Because shock events can be extremely damaging, mechanical shock is an important topic for engineers to understand. This book provides the reader with the tools needed to quantitatively describe shock environments and their damage potential on aerospace, civil, naval and mechanical systems. The authors include the relevant history of how shock testing and analysis came to its current state and a discussion of the different types of shock environments typically experienced by systems. Development of single-degree-of-freedom theory and the theory of the shock response spectra are covered, consistent with treatment of shock spectra theory in the literature. What is unique is the expansion to other types of spectra including less common types of shock spectra and energy spectra methods using fundamental principles of structural dynamics. In addition, non-spectral methods are discussed with their applications. Non-spectral methods are almost completely absent from the current books on mechanical shock. Multi-degree-of-freedom shock spectra and multi-degree-of-freedom testing are discussed and the theory is developed. Addressing an emerging field for laboratory shock testing, the authors bring together information currently available only in journals and conference publications. The volume is ideal for engineers, structural designers, and structural materials fabricators needing a foundation to practically analyze shock environments and understand their role in structural design.

IFToMM conferences have a history of success due to the various advances achieved in the field of rotor dynamics over the past three decades. These meetings have since become a leading global event, bringing together specialists from industry and academia to promote the exchange of knowledge, ideas, and information on the latest developments in the dynamics of rotating machinery. The scope of the conference is broad, including e.g. active components and vibration control, balancing, bearings, condition monitoring, dynamic analysis and stability, wind turbines and generators, electromechanical interactions in rotor dynamics and turbochargers. The proceedings are divided into four volumes. This second volume covers the following main topics: condition monitoring, fault diagnostics and prognostics; modal testing and identification; parametric and self-excitation in rotor dynamics; uncertainties, reliability and life predictions of rotating machinery; and torsional vibrations and geared systems dynamics.
