Mathematical Elasticity
Volume II: Theory of Plates
1st Edition
Volume 27
English
The objective of Volume II is to show how asymptotic methods, with the thickness as the small parameter, indeed provide a powerful means of justifying two-dimensional plate theories. More specifically, without any recourse to any a priori assumptions of a geometrical or mechanical nature, it is shown that in the linear case, the three-dimensional displacements, once properly scaled, converge in H1 towards a limit that satisfies the well-known two-dimensional equations of the linear Kirchhoff-Love theory; the convergence of stress is also established.In the nonlinear case, again after ad hoc scalings have been performed, it is shown that the leading term of a formal asymptotic expansion of the three-dimensional solution satisfies well-known two-dimensional equations, such as those of the nonlinear Kirchhoff-Love theory, or the von Kármán equations. Special attention is also given to the first convergence result obtained in this case, which leads to two-dimensional large deformation, frame-indifferent, nonlinear membrane theories. It is also demonstrated that asymptotic methods can likewise be used for justifying other lower-dimensional equations of elastic shallow shells, and the coupled pluri-dimensional equations of elastic multi-structures, i.e., structures with junctions. In each case, the existence, uniqueness or multiplicity, and regularity of solutions to the limit equations obtained in this fashion are also studied.
Time and Behaviour
Psychological and Neurobehavioural Analyses
1st Edition
Volume 120
C.M. Bradshaw + 1 more
English
That time is both a dimension of behaviour and a ubiquitous controlling variable in the lives of all living things has been well recognized for many years.The last decade has seen a burgeoning of interest in the quantitative analysis of timing behaviour, and progress during the last five or six years has been particularly impressive, with the publication of several major new theoretical contributions.There has also been considerable progress in behavioural methodology during the past decade. In the area of reinforcement schedules, for example, the venerable interresponse–time schedule, fixed–interval peak procedure and interval bisection task have been complemented by a 'second generation' of incisive instruments for analyzing timing behaviour.Another area of recent development is the analysis of the neurobiological substrate of timing behaviour. Several research groups are currently studying the involvement of various central neurotransmitter systems in the timing behaviour, and the ability of centrally acting drugs and discrete brain lesions to alter timing processes. Yet another recent development in timing research is the growing dialogue between two fields that have grown up separately, although, superficially at least, they seem to have much in common: the experimental analysis of 'interval timing', traditionally the province of experimental psychology, and behavioural chronobiology. The last few years have seen a growing interest in the comparative properties of the internal 'clocks' that regulate biobehavioural rhythms with time bases in the circadian range or longer, and those that are entailed in timing of intervals in the range of seconds or minutes.All these areas of research, and others, are represented in the chapters that make up this volume. This book will help to promote further interactions among researchers who hail from disparate disciplines, but who share a common interest in the temporal properties of behaviour.
Handbook of Population and Family Economics
1st Edition
Volume 1AB
O. Stark + 1 more
English
The collection of chapters in the Handbook of Population and Family Economics and their organization reflect the most recent developments in economics pertaining to population issues and the family. The rationale, contents, and organization of the Handbook evolve from three premises. First, the family is the main arena in which population outcomes are forged. Second, there are important interactions and significant causal links across all demographic phenomena. Third, the study of the size, composition, and growth of a population can benefit from the application of economic methodology and tools. The diversity and depth of the work reviewed and presented in the Handbook conveys both the progress that has been made by economists in understanding the forces shaping population processes, including the behavior of families, and the many questions, empirical and theoretical, that still remain.

Submodular Functions and Electrical Networks
1st Edition
Volume 54
H. Narayanan
English
There is a strong case for electrical network topologists and submodular function theorists being aware of each other's fields.Presenting a topological approach to electrical network theory, this book demonstrates the strong links that exist between submodular functions and electrical networks.The book contains:• a detailed discussion of graphs, matroids, vector spaces and the algebra of generalized minors, relevant to network analysis (particularly to the construction of efficient circuit simulators)• a detailed discussion of submodular function theory in its own right; topics covered include, various operations, dualization, convolution and Dilworth truncation as well as the related notions of prinicpal partition and principal lattice of partitions.In order to make the book useful to a wide audience, the material on electrical networks and that on submodular functions is presented independently of each other. The hybrid rank problem, the bridge between (topological) electrical network theory and submodular functions, is covered in the final chapter.The emphasis in the book is on low complexity algorithms, particularly based on bipartite graphs.The book is intended for self-study and is recommended to designers of VLSI algorithms. More than 300 problems, almost all of them with solutions, are included at the end of each chapter.

Covering Codes
1st Edition
Volume 54
G. Cohen + 3 more
English
The problems of constructing covering codes and of estimating their parameters are the main concern of this book. It provides a unified account of the most recent theory of covering codes and shows how a number of mathematical and engineering issues are related to covering problems.Scientists involved in discrete mathematics, combinatorics, computer science, information theory, geometry, algebra or number theory will find the book of particular significance. It is designed both as an introductory textbook for the beginner and as a reference book for the expert mathematician and engineer.A number of unsolved problems suitable for research projects are also discussed.
Intelligent Environments
Spatial Aspects of the Information Revolution
1st Edition
P. Droege
English
The environment, as modified and created by people, is largely about the use of information, its generation and exchange. How do recent innovations in the technologies of information management and communication affect our use of space and place, and the way we perceive and think about our surroundings?This volume provides an international, exploratory forum for the complex phenomenon of new information and communication technology as it permeates and transforms our physical world, and our relation to it: the architectural definition of our surrounding, geographical space, urban form and immediate habitats. This book is a reader, an attempt at registering disciplinary changes in context, at tracing subtexts for which most mainstream disciplines have no established language. The project is to give voice to an emerging meta-discipline that has its logic across the specializations.A wide range of professionals and academics report findings, views and ideas. Together, they describe the architecture of a postmodern paradigm: how swiftly mutating the proliferating technology applications have begun to interact with the construction and reading of physical space in architecture, economics, geography, history, planning, social sciences, transport, visual art - but also in the newer domains that have joined this spectrum through the very nature of their impacts: information technology and telecommunications.T... space navigated in this volume is vast, both in physical terms and in its virtual and analogous form. It ranges from the space that immediately encompasses, or is simulated to encompass, the human body - as in buildings and virtual tectonics - to that of towns and regions. We stay clear of molecular-scale space, and of dimensions that are larger than earth.
Self-Organization, Computational Maps, and Motor Control
1st Edition
Volume 119
P.G. Morasso + 1 more
English
In the study of the computational structure of biological/robotic sensorimotor systems, distributed models have gained center stage in recent years, with a range of issues including self-organization, non-linear dynamics, field computing etc. This multidisciplinary research area is addressed here by a multidisciplinary team of contributors, who provide a balanced set of articulated presentations which include reviews, computational models, simulation studies, psychophysical, and neurophysiological experiments.The book is divided into three parts, each characterized by a slightly different focus: in part I, the major theme concerns computational maps which typically model cortical areas, according to a view of the sensorimotor cortex as "geometric engine" and the site of "internal models" of external spaces. Part II also addresses problems of self-organization and field computing, but in a simpler computational architecture which, although lacking a specialized cortical machinery, can still behave in a very adaptive and surprising way by exploiting the interaction with the real world. Finally part III is focused on the motor control issues related to the physical properties of muscular actuators and the dynamic interactions with the world.The reader will find different approaches on controversial issues, such as the role and nature of force fields, the need for internal representations, the nature of invariant commands, the vexing question about coordinate transformations, the distinction between hierachiacal and bi-directional modelling, and the influence of muscle stiffness.
