Nonlinear Problems of Engineering
1st Edition
William F. Ames
English
Nonlinear Problems of Engineering reviews certain nonlinear problems of engineering. This book provides a discussion of nonlinear problems that occur in four areas, namely, mathematical methods, fluid mechanics, mechanics of solids, and transport phenomena. Organized into 15 chapters, this book begins with an overview of some of the fundamental ideas of two mathematical theories, namely, invariant imbedding and dynamic programming. This text then explores nonlinear integral equations, which have long occupied a prominent place in mathematical analysis. Other chapters consider the phenomena associated with essentially divergent small-divisor series, such as may occur in the formal solution of differential equations that represent the oscillations of conservative dynamical systems.

Chemical Determinations
1st Edition
Ralph I. Dorfman
English
Chemical Determinations is a collection of papers that discusses chemical methods used in hormone investigation. One paper explains the physicochemical procedures used to separate estrogens from interfering material which leads to the possible determination of small amounts of hormones in biological fluids. One approach is through simpler methods for routine use, designed principally for the determination of estrogens in urine and in plasma. Another way is through more elaborate methods, designed to establish the presence and identity of various estrogens in small numbers of biological samples. Another paper explains the methods for the analysis of 17-ketosteroids of blood and urine, and a method for the assay of testosterone in plasma which correlates with the state of virilism of an individual. One paper describes the techniques utilized for extraction, preliminary purification, isolation, and quantitative estimation of progesterone. Another paper reviews the occurrence of pregnanetriolone (an inactive urinary metabolite), the significance of its estimation as an aid in differential diagnosis, the methods of estimation, as well as the metabolic pathways leading to the excretion of pregnanetriolone and related steroids. The collection is suitable for researchers, scientists, medical practitioners, or academicians involved in endocrinology, metabolism, and bio-research.
Computer Arithmetic in Theory and Practice
1st Edition
Ulrich W. Kulisch + 1 more
Werner Rheinboldt
English
Computer Arithmetic in Theory and Practice deals with computer arithmetic and the various implementations of the entire arithmetic package on diverse processors, including microprocessors. It illustrates the importance of theoretical development in the sound implementation of arithmetic on computers, and argues that such an implementation requires the establishment of various isomorphisms between different definitions of arithmetic operations. Comprised of seven chapters, this volume begins with an introduction to the theory of computer arithmetic by giving an axiomatic characterization of the essential properties of sets and subsets; complete lattices and complete subnets; screens and roundings; and arithmetic operations. The discussion then turns to the concepts of a ringoid and a vectoid as well as those of ordered or weakly ordered ringoids and vectoids; interval arithmetic; and floating-point arithmetic. The operations in interval spaces are defined by means of semimorphisms. The final chapter shows how to embed the five basic data types (integer, real, complex, real interval, and complex interval) together with the arithmetic operations that are defined for all of these types into existing higher programming languages. This book will be helpful to students and practitioners in the fields of computer science and applied mathematics.
