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
This book reviews ancient and modern representations and explanations of hierarchies, and compares their relevance in a variety of fields, such as language, societies, cities, and living species. 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.
Hierarchical Matrices : A Means to Efficiently Solve Elliptic Boundary Value Problems
Hierarchical matrices are an efficient framework for large-scale fully populated matrices arising, e.g., from the finite element discretization of solution operators of elliptic boundary value problems. In addition to storing such matrices, approximations of the usual matrix operations can be computed with logarithmic-linear complexity, which can be exploited to setup approximate preconditioners in an efficient and convenient way. Besides the algorithmic aspects of hierarchical matrices, the main aim of this book is to present their theoretical background. The book contains the existing approximation theory for elliptic problems including partial differential operators with nonsmooth coefficients.

Hexagonal image processing : A practical approach
Hexagonal Image Processing provides an introduction to the processing of hexagonally sampled images, includes a survey of the work done in the field, and presents a novel framework for hexagonal image processing (HIP) based on hierarchical aggregates. Digital image processing is currently dominated by the use of square sampling lattices, however, hexagonal sampling lattices can also be used to define digital images. The strengths offered by hexagonal lattices over square lattices are considerable: • higher packing density, • uniform connectivity of points (pixels) in the lattice, • better angular resolution by virtue of having more nearest neighbours, and • superlative representation of curves. The utility of the HIP framework is demonstrated by implementing several basic image processing techniques (for the spatial and frequency domain) and some applications. The HIP framework serves as a tool for comparing processing of images defined on a square vs hexagonal grid, to determine their relative merits and demerits. The theory and algorithms covered are supplemented by attention to practical details such as accommodating hardware that support only images sampled on a square lattice. Including a Foreword written by Professor Narendra Ahuja, an eminent researcher in the field of Image Processing and Computer Vision, the book’s fresh approach to the subject offers insight and workable know-how to both researchers and postgraduates.

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.
Heterogeneity in statistical genetics : How to assess, address, and account for mixtures in association studies
Heterogeneity, or mixtures, are ubiquitous in genetics. Even for data as simple as mono-genic diseases, populations are a mixture of affected and unaffected individuals. Still, most statistical genetic association analyses, designed to map genes for diseases and other genetic traits, ignore this phenomenon.In this book, we document methods that incorporate heterogeneity into the design and analysis of genetic and genomic association data. Among the key qualities of our developed statistics is that they include mixture parameters as part of the statistic, a unique component for tests of association. A critical feature of this work is the inclusion of at least one heterogeneity parameter when performing statistical power and sample size calculations for tests of genetic association.

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.

Hepatitis Delta Virus ; Vol. 307
Since its discovery nearly 30 years ago, hepatitis delta virus (HDV) has continued to surprise and fascinate. At 1,680 nucleotides the HDV genome is the smallest known to infect man. It is unique among animal viruses, the closest known relatives being plant viroids. To compensate for its limited protein coding capacity, HDV relies heavily on host functions and on structural features of its circular RNA genome. HDV infection depends on hepatitis B virus as a helper, and increases the severity of liver disease caused by HBV alone. There is currently neither an effective HDV vaccine nor a generally accepted useful therapy for HDV infection. This volume encompasses recent developments in HDV research, from molecular virology to genetics to experimental investigation of new therapeutic and vaccine candidates.
