This computationally oriented book describes and explains the mathematical relationships among matrices, moments, orthogonal polynomials, quadrature rules, and the Lanczos and conjugate gradient algorithms. The book bridges different mathematical areas to obtain algorithms to estimate bilinear forms involving two vectors and a function of the matrix. The first part of the book provides the necessary mathematical background and explains the theory. The second part describes the applications and gives numerical examples of the algorithms and techniques developed in the first part.
Applications addressed in the book include computing elements of functions of matrices; obtaining estimates of the error norm in iterative methods for solving linear systems and computing parameters in least squares and total least squares; and solving ill-posed problems using Tikhonov regularization.
This book will interest researchers in numerical linear algebra and matrix computations, as well as scientists and engineers working on problems involving computation of bilinear forms.
For more than forty years, the equation y (t) = Ay(t) + u(t) in Banach spaces has been used as model for optimal control processes described by partial differential equations, in particular heat and diffusion processes. Many of the outstanding open problems, however, have remained open until recently, and some have never been solved. This book is a survey of all results know to the author, with emphasis on very recent results (1999 to date).
This third edition of A Dictionary of Virology offers an authoritative, concise, and up-to-date list of all viruses affecting vertebrate species, from humans to fish.

The entries have been restructured so that all viruses are listed and classified in accordance with the standards set by the 7th Report of the ICTV. The extensive cross-referencing and illustrative tables further enhance the utility of this reference.
A Textbook on Macroeconomic Knowledge and Analysis
Hardbound. This reference work covers the many aspects of Robust Inference. Much of what is contained in the chapters, written by leading experts in the field, has not been part of previous surveys of this area. Robust Inference has been an active area of research for the last two decades. Especially during recent years it has been extended in different directions covering a wide variety of models. This volume will be valuable for both graduate students and researchers using statistical methods.
Volume I provides a detailed analysis of cylindric algebras, starting with a formulation of their axioms and a development of their elementary properties, and proceeding to a deeper study of their interrelationships by means of general algebraic notions such as subalgebras, homomorphisms, direct products, free algebras, reducts and relativized algebras.
Soft Scale Insects is intended to be a further step towards providing comprehensive information on soft scale insects. Four or five decades ago, entomologists embarking on a study on soft scale insects would have encountered a scarcity of general text books or comprehensive treatise of the family, as a starting point for their research. At the time, the available knowledge and data were either scattered among numerous articles or regional monographs or were in obsolete books. It is hoped that this volume will cover almost the entire spectrum of the knowledge on the soft scale insect family, Coccidae. This book comprises six chapters and begins by discussing the natural enemies of soft scale insects, such as pathogens like entomopathogenic fungi; predators like coccineilidae and other coleoptera; and parasitoids like encyrtidae. It then discusses issues of damage and control, including pest status of soft scale insects and coccid pests of important crops. This book will be of interest to entomologists, horticulturists, zoologists, biologists, and those involved in general agricultural research.
The Lanczos and conjugate gradient (CG) algorithms are fascinating numerical algorithms. This book presents the most comprehensive discussion to date of the use of these methods for computing eigenvalues and solving linear systems in both exact and floating point arithmetic. The author synthesizes the research done over the past 30 years, describing and explaining the "average" behaviour of these methods and providing new insight into their properties in finite precision. Many examples are given that show significant results obtained by researchers in the field. The author emphasizes how both algorithms can be used efficiently in finite precision arithmetic, regardless of the growth of rounding errors that occurs. He details the mathematical properties of both algorithms and demonstrates how the CG algorithm is derived from the Lanczos algorithm. Loss of orthogonality involved with using the Lanczos algorithm, ways to improve the maximum attainable accuracy of CG computations, and what modifications need to be made when the CG method is used with a preconditioner are addressed.
This book deals with topics such as single molecular electronics and photonics, NICE devices, smart soft materials, interfacial dynamic technology, and fabrication and characterization technology.
This two-volume book presents an up-to-date account of armored
scale insects (Homoptera: Diaspididas), a family of highly
specialized insects, many of which are important agricultural
pests. Being sedentary, colonial and rather cryptic, many species
have invaded new countries with important host plants. This has
made them prime targets for biological control by natural enemies.

The Progress in Medicinal Chemistry series is a respected and instructive source of information on the subject. It has a long established reputation for excellent coverage of almost every facet of medicinal chemistry. This volume includes information on the discovery and development of Atorvastatin; the discovery of CEP-1347/KT-7515, an JNK/SAPK pathway for the treatment of neurodegenerative diseases such; and the discovery of second generation Quinazolinone non-nucleoside reverse transcriptase inhibitors of HIV-1; and molecular modeling of Opioid receptor-Ligand complexes.
Satellite communications technology is a tremendous force for change and innovation. From the first satellite telephone call, to the moon landing in 1969, to today's global coverage of the Olympics with more than 3 billion viewers, satellites have helped create a world community. From $300trillion annually in worldwide electronic funds transfers to hundreds of millions of airline reservations, satellites play critical roles in finance, business and international trade. Despite growth in fiber optic cables, some 60% of all overseas communications is satellite based. Today, more than 200 countries and territories rely on about 200 satellites for domestic, regional and/or global linkages, defense communications, direct broadcast services, navigation, data collection, and mobile communications. Satellite communications is the largest and most successful of all commercial space enterprises-it is currently a $15 billion per year business which could grow to $30 billion per year within the decade.
In the mid-1960s, when satellite communications first became a commercial reality, the United States was not just the leader, but was predominant in every aspect from launch vehicles to satellite technology. The agreements under which the International Telecommunications Satellite Organization (INTELSAT) were established were originally negotiated on an interim basis only, giving the United States a dominant leadership role. Japan and Europe felt they would need a number of years to enter seriously into the field. Today, more than a quarter of a century later, conditions have changed dramatically.
The focus of this study is on experimental and advanced technology being developed in R&D anddemonstration programs rather than on today's production capabilities. The report focuses on commercial satellite technology, and does not review defense-related or other confidential satellite communications capabilities. The NASNNSF panel concluded that the United States has lost its leading position in many critical satellite communications technologies.

This two-part volume with contributions from more than 50 international specialists, provides an up-to-date text and brings together facts and views of acarologists specialized in various aspects of the biology of spider mites. The need for such a treatment of scientific progress and recommended topics for future research exists among students, commencing in the study of acarology and plant protection, as well as among those engaged in acarological research and teaching. Both books will serve to provide a synthesis of much of the knowledge on basic and applied aspects of the biology of spider mites and their natural enemies; stimulate students to analyse critically the views propounded by the authors of the book, and instigate research into environmentally safe and cost effective means of pest control.
This text presents an up-to-date account of the soft-scale insects, "Coccidae", and covers almost the entire spectrum of the knowledge of this insect family. It is divided into three sections, covering: soft scale insects; their natural enemies; and damage and control.
In spite of the extensive attention given by research workers to aphids no comprehensive review has been published covering all aspects of aphid biology. A few small books exist on certain aspects of nomenclature, ecology, physiology and natural enemies. Aphid biology is studied by many specialists, all representing their own area of interest, therefore the only way to present this comprehensive review is by the multi-author approach. This three-volume work is compiled in a similar way to the first books in the series World Crop Pests: Spider Mites. The volumes contain contributions by more than 40 authors. In this first volume an account is given on morphology and systematics, anatomy, genetics, life cycles, ways of life, reproduction and polymorphism and interaction with the environment. These topics are followed by an in-depth study of evolution of aphids, especially in connection with the evolution of plants. In addition processes governing the development of population structure and speciation are elicited.
This first part presents chapters on models of computation,
complexity theory, data structures, and efficient computation in
