High-Energy Spectroscopic Astrophysics : Saas Fee Advanced Course 30. Lecture Notes 2000. Swiss Society for Astrophysics and Astronomy
After three decades of intense research in X-ray and gamma-ray astronomy, the time was ripe to summarize basic knowledge on X-ray and gamma-ray spectroscopy for interested students and researchers ready to become involved in new high-energy missions. This volume exposes both the scientific basics and modern methods of high-energy spectroscopic astrophysics. The emphasis is on physical principles and observing methods rather than a discussion of particular classes of high-energy objects, but many examples and new results are included in the three chapters as well.

High Energy Polarized Proton Beams : A Modern View
This monograph begins with a review of the basic equations of spin motion in particle accelerators. It then reviews how polarized protons can be accelerated to several tens of GeV using as examples the preaccelerators of HERA, a 6.3 km long cyclic accelerator at DESY / Hamburg. Such techniques have already been used at the AGS of BNL / New York, to accelerate polarized protons to 25 GeV. But for acceleration to energies of several hundred GeV as in RHIC, TEVATRON, HERA, LHC, or a VLHC, new problems can occur which can lead to a significantly diminished beam polarization. For these high energies, it is necessary to look in more detail at the spin motion, and for that the invariant spin field has proved to be a useful tool. This is already widely used for the description of high-energy electron beams that become polarized by the emission of spin-flip synchrotron radiation. It is shown that this field gives rise to an adiabatic invariant of spin-orbit motion and that it defines the maximum time average polarization available to a particle physics experiment.
High Energy Density Materials
The series Structure and Bonding publishes critical reviews on topics of research concerned with chemical structure and bonding. The scope of the series spans the entire Periodic Table. It focuses attention on new and developing areas of modern structural and theoretical chemistry such as nanostructures, molecular electronics, designed molecular solids, surfaces, metal clusters and supramolecular structures. Physical and spectroscopic techniques used to determine, examine and model structures fall within the purview of Structure and Bonding to the extent that the focus is on the scientific results obtained and not on specialist information concerning the techniques themselves.
High Availability and Disaster Recovery : Concepts, Design, Implementation
Companies and other organizations depend more than ever on the availability of their Information Technology, and most mission critical business processes are IT-based processes. Business continuity is the ability to do business under any circumstances and is an essential requirement modern companies are facing. High availability and disaster recovery are contributions of the IT to fulfill this requirement. And companies will be confronted with such demands to an even greater extent in the future, since their credit ratings will be lower without such precautions. Both, high availability and disaster recovery, are realized by redundant systems. Redundancy can and should be implemented on different abstraction levels: from the hardware, the operating system and middleware components up to the backup computing center in case of a disaster. This book presents requirements, concepts, and realizations of redundant systems on all abstraction levels, and all given examples refer to UNIX and Linux systems.
Hierarchy in Natural and Social Sciences

It throws light on concepts and models such as scaling laws, fractals and self-organisation that are fundamental in the dynamics and morphology of complex systems.This book addresses a wide audience of biologists and social scientists, as well as managers and executives in a variety of institutions.
Heterogeneous Enantioselective Hydrogenation : Theory and Practice
The book looks at the first relatively ineffective catalysts right through to modern highly effective enantioselective catalytic systems, comparable in their efficiency to chiral metal complexes and enzymatic systems. The book begins with a summary of the first work on heterogeneous metal catalysts, which showed only the principal possibilities of enantioselective reactions. The book then elaborates on metal catalysts which have enantioselectivities close to 100%. Finally, the book describes the practical utilization of chiral catalytic systems in processes of hydrogenation. The a - and b -hydroxy carboxylic acid esters produced are precursors for manufacturing many synthones used for medicines as well as for monomers used for biodegradable polyesters, both of which have important practical applications. The book summarizes more than 800 scientific papers in the field of enantioselective catalytic hydrogenation reactions, mainly those using heterogeneous metal catalysts. It provides detailed explanations of special techniques for the preparation of effective dissymmetric catalysts which provide highly efficient catalytic systems.
Heterocycles from Carbohydrate Precursors
This book is a volume in the series Topics in Heterocyclic Chemistry.Itc- ers the key methods used for designing synthetic approaches to heterocycles from carbohydrates and the value and scope of these methods. Carbohydrates are widely distributed in nature and constitute the largest part of renewable biomasses. Moreover, many carbohydrates and their derivatives are comm- cially available at relatively cheap prices. Consequently their utilization is highly encouraged and economically they are of great signifcance. Moreover, carbohydrates are highly functionalized compounds that can be readily deritized and/or cyclized to provide heterocyclic compounds. This book provides a modern account and an up-to-date description of the advancement in the synthesis of diverse heterocycles from carbohydrates. Carbohydrates can be considered as a source of chiral centers in addition to the variable modifcation thereof.
Hermeneutics and Hindu Thought : Toward a Fusion of Horizons
The emergence of Hinduism as a field of study in the Western academia coincides with the development of modern hermeneutics. Despite this coemergence, and the rich possibilities inherent in a dialectical encounter between the theories of modern and pre-modern hermeneutics and those of Hindu hermeneutical traditions, this potential has not been tapped within the boundaries of religious studies. This volume sets out to initiate such an interface.Some essays in this volume, such as those by Shrinivas Tilak, Sharada Sugirtharajah, and Purushottama Bilimoria examine the impact of Western hermeneutics on the Indian religious landscape.

Heaven Upon Earth : Joseph Mede (1586-1638) and the Legacy of Millenarianism
THE HISTORY OF BRITISHAPOCALYPTICTHOUGHT The study of early modern Britain between the Reformation of the 1530s and the Wars of the Three Kingdoms of the 1640s has undergone a series of historiographical revisions. The dramatic events during that century were marked by a religious struggle that produced a Protestant nation, divided internally, yet clearly opposed to Rome. Likewise the political environment instilled a sense of responsible awareness regarding the administration of the realm and the defense 1 of constitutional liberty. Whig Historians from the nineteenth century described 2 these changes as a “Puritan Revolution.”

Harnessing the Power of the Criminal Corpse
This book is the culmination of many years of research on what happened to the bodies of executed criminals in the past. Focusing on the eighteenth and nineteenth centuries, it looks at the consequences of the 1752 Murder Act. These criminal bodies had a crucial role in the history of medicine, and the history of crime, and great symbolic resonance in literature and popular culture. Starting with a consideration of the criminal corpse in the medieval and early modern periods, chapters go on to review the histories of criminal justice, of medical history and of gibbeting under the Murder Act, and ends with some discussion of the afterlives of the corpse, in literature, folklore and in contemporary medical ethics. Using sophisticated insights from cultural history, archaeology, literature, philosophy and ethics as well as medical and crime history, this book is a uniquely interdisciplinary take on a fascinating historical phenomenon.
Harmonic Analysis and Rational Approximation : Their Rôles in Signals, Control and Dynamical Systems

After a general introduction, Part II of this volume contains basic material on the complex and harmonic analysis underlying the further developments presented. Part III deals with the essentials of approximation theory while Part IV completes the foundations by a tour of probability theory. Part V reviews some major applications in signal and control theory. In Part VI mathematical aspects of dynamical systems theory are discussed. Part VII, finally, is devoted to a modern approach to two physics problems: turbulence and the control and noise analysis in gravitational waves measurements.
Hard Disk Drive Servo Systems
The second edition of this monograph provides a systematic treatment of the design of modern hard disk drive servo systems updated with the latest research results to reflect recent improvements in spindle speed and bit density and other changes in this fast-moving field. In particular, it focuses on the applications of some newly developed results in control theory, i.e., robust and perfect tracking control and composite non-linear feedback control which are suitable for track following and seeking respectively. Emphasis is placed on hard disk drive servo systems with single- or dual-stage actuation using a voice-coil-motor actuator enhanced in the latter case by the addition of a micro-actuator providing faster responses and therefore higher bandwidth in track following. Other issues such as modeling and compensation of nonlinearities and friction in microdrives, disturbance rejection and resonance compensation are also addressed.
Hans Christian Ørsted and the Romantic Legacy in Science : Ideas, Disciplines, Practices
This volume owes its origin to the perception of a puzzling paradox. Hans Christian Ørsted, the great Danish scientist and philosopher, was one of the founders of modern physics through his experimental discovery in 1820 of the interaction of electricity and magnetism—a key step and model for the further unification of the forces of nature. Followers such as Maxwell and Einstein were, and today searchers worldwide are, enchanted by the hope for a completion of that grand program. In addition to Ørsted’s discovery of electromagnetism, his work in science included other fields, chiefly high-pressure physics and acoustics.
