Buch. Zustand: Neu. Neuware - The last decade has seen a major growth in research on how memory is used in everyday life. This volume represents a reaction to traditional laboratory-bound studies of the first half of the century which sought to identify the fundamental principles of learning and memory through the use of materials and methods totally divorced from the real world. The new wave of memory research has had considerable success in charting how memory develops, the role it plays in educational and social skills and the impact of memory impairment on mental life. The current volume consists of authoritative reviews of this emerging area linked to comment and criticism from major researchers in the field.Contrasted, probably for the first time, are two major styles of research in applied memory research: The naturalistic approach, which has sought to study memory in everyday environments, using actual experiences from people's lives as the raw data from which to derive more general principles, and the applied cognitive approach, whereby theories and methods are developed using orthodox laboratory techniques which are then validated by applying them directly to real phenomena. This is one of the few books to bring together evidence across the very wide spectrum of humdrum activity that constitutes the everyday uses of memory.…

Buch. Zustand: Neu. Neuware - Presented in this monograph is the current state-of-the-art in the theory of convex structures. The notion of convexity covered here is considerably broader than the classic one; specifically, it is not restricted to the context of vector spaces. Classical concepts of order-convex sets (Birkhoff) and of geodesically convex sets (Menger) are directly inspired by intuition; they go back to the first half of this century. An axiomatic approach started to develop in the early Fifties. The author became attracted to it in the mid-Seventies, resulting in the present volume, in which graphs appear side-by-side with Banach spaces, classical geometry with matroids, and ordered sets with metric spaces. A wide variety of results has been included (ranging for instance from the area of partition calculus to that of continuous selection). The tools involved are borrowed from areas ranging from discrete mathematics to infinite-dimensional topology.Although addressed primarily to the researcher, parts of this monograph can be used as a basis for a well-balanced, one-semester graduate course.…

Buch. Zustand: Neu. Neuware - Handbook of Convex Geometry, Volume A offers a survey of convex geometry and its many ramifications and relations with other areas of mathematics, including convexity, geometric inequalities, and convex sets. The selection first offers information on the history of convexity, characterizations of convex sets, and mixed volumes. Topics include elementary convexity, equality in the Aleksandrov-Fenchel inequality, mixed surface area measures, characteristic properties of convex sets in analysis and differential geometry, and extensions of the notion of a convex set. The text then reviews the standard isoperimetric theorem and stability of geometric inequalities. The manuscript takes a look at selected affine isoperimetric inequalities, extremum problems for convex discs and polyhedra, and rigidity. Discussions focus on include infinitesimal and static rigidity related to surfaces, isoperimetric problem for convex polyhedral, bounds for the volume of a convex polyhedron, curvature image inequality, Busemann intersection inequality and its relatives, and Petty projection inequality. The book then tackles geometric algorithms, convexity and discrete optimization, mathematical programming and convex geometry, and the combinatorial aspects of convex polytopes. The selection is a valuable source of data for mathematicians and researchers interested in convex geometry.…

Buch. Zustand: Neu. Neuware - The aim of this book is to introduce a range of combinatorial methods for those who want to apply these methods in the solution of practical and theoretical problems. Various tricks and techniques are taught by means of exercises. Hints are given in a separate section and a third section contains all solutions in detail. A dictionary section gives definitions of the combinatorial notions occurring in the book.Combinatorial Problems and Exercises was first published in 1979. This revised edition has the same basic structure but has been brought up to date with a series of exercises on random walks on graphs and their relations to eigenvalues, expansion properties and electrical resistance. In various chapters the author found lines of thought that have been extended in a natural and significant way in recent years. About 60 new exercises (more counting sub-problems) have been added and several solutions have been simplified.…

Buch. Zustand: Neu. Neuware - The Concise Encyclopedia of Environmental Systems provides a concise overview of the current state of the art in the study of environmental systems. Contains specially commissioned articles and updated and revised articles from the acclaimed Systems & Control Encyclopedia. The subjects covered include: agricultural systems; atmospheric processes and air quality; ecosystems; environmental chemistry; geology, soil processes and geophysics; hydrology, fluid dynamics and water quality; marine processes; meteorology; and climatology. In addition, many of the articles cover the methodological procedures used in environmental systems analysis, with contributions on automatic control and management; computers in modelling and management; environmental planning; environmetric methods, including time-series analysis; mathematical modelling, including data-based, physically based and simulation modelling; remote sensing and image processing; uncertainty in environmental systems; and sensitivity analysis. The encyclopedia is extensively cross-referenced on two levels - to articles of direct relevance as well as to other articles which will provide the reader with more general background information.…
