The area of intelligent and adaptive user interfaces has been of interest to the research community for a long time. Much effort has been spent in trying to find a stable theoretical base for adaptivity in human-computer interaction and to build prototypical systems showing features of adaptivity in real-life interfaces. To date research in this field has not led to a coherent view of problems, let alone solutions. A workshop was organized, which brought together a number of well-known researchers in the area of adaptive user interfaces with a view to

develop a coherent view of the results accomplished in the field

organize basic ideas which might lead to a more general methodology for adaptivity in order to overcome the problem of specialized, non-generalizable solutions, and

discuss possible areas for future research in the field and to define criteria for the selection of the most promising directions of such research.

The results of the workshop are presented in this volume. The authors have collected papers from the participants which describe both their research and their views on questions which were dealt with during the workshop. A state-of-the-art report and taxonomy for the field of adaptive interfaces and a discussion summary are also included in this volume.

Probability is relevant to so many different subject areas that its importance as a mathematical technique cannot be underestimated. This book provides a comprehensive, user-friendly introduction to the subject. The step-by-step approach taken by the author allows students to develop knowledge at their own pace and, by working through the numerous exercises, they are ensured a full understanding of the material before moving on to more advanced sections. Traditional examples of probablistic theory, such as coins and dice, are included but the author has also used many exercises based on real-life problems. The result is an introduction to probability that avoids the overly confusing, theoretical approach often adopted in this area, and provides a simple and concise text that will be invaluable to all studying first and second year courses on the subject.

This text provides an introduction to group theory with an emphasis on clear examples. The authors present groups as naturally occurring structures arising from symmetry in geometrical figures and other mathematical objects. Written in a 'user-friendly' style, where new ideas are always motivated before being fully introduced, the text will help readers to gain confidence and skill in handling group theory notation before progressing on to applying it in complex situations. An ideal companion to any first or second year course on the topic.

The pre-eminent 19th century British ethicist, Henry Sidgwick once said:
"All important ethical notions are also psychological, except perhaps the fundamental antitheses of 'good' and 'bad' and 'wrong', with which psychology, as it treats of what is and not of what ought to be, is not directly concerned" (quoted in T.N. Tice and T.P. Slavens, 1983).
Sidgwick's statement can be interpreted to mean that psychology is relevant for ethics or that psychological knowledge contributes to the construction of an ethical reality. This interpretation serves as the basic impetus to this book, but Sidgwick's statement is also analyzed in detail to demonstrate why a current exposition on the relevance of psychology for ethical reality is necessary and germane.

In recent years, the main research areas were photonuclear reactions and meson productions by using the first high-duty tagged photon beam and the TAGX spectrometer. Although this field is developing quite rapidly, the synchrotron was closed in 1999 after 37 years of operation, and these activities continue at new facilities. It was therfore a good time to discuss the present status and future directions of this field at this occasion. The Symposium was attended by 85 physicists and 35 talks were presented. This book contains the papers presented in the scientific program of the Symposium.

This is the 17th volume in an annual series of reviews of research in organizational behaviour. This volume cover such topics as the development of a theory of timing, a framework for the integration of micro- and macro-organizational behaviour, and population-level learning.

This volume covers the computational dynamics of linear and non-linear engineering systems subject to conservative as well as non-conservative loads. Available in both paperback and hardback, the volume proposes an as simple as possible numerical evaluation of dynamic phenomena.
p]
Practically all known methods of linear spectral analysis like the Householder, Givens, Wiland, Lanczos, Jacobi, Guyan, Eberlein, etc., are clearly detailed with a critical appraisal of their advantages and disadvantages. A great number of flow diagrams and examples are given in order to facilitate the understanding and practical application. A technically experienced reader will no doubt appreciate the interpretative difficulties of a subject like random or stochastic vibration expounded in a special chapter. Non-model damping is also detailed and the highly topical direct integration methods of the equations of dynamic equilibrium receive a very broad description.
p]
Finally non-linear oscillations are analysed mostly from the computational point of view. Here the Newmark and the Hermitean algorithms receive very detailed accounts and a critical appraisal. At the same time the subject of non-linear oscillations is introduced through a semi-analytical discussion of the Duffing equation in which the various attractor systems in phase space including strange attractors for chaotic manifestation are described.
p]
This volume is the first to appear in this series of self-contained textbooks designed to present a modern, comprehensive account of computational mechanics, which will appeal to both student and experienced practitioner alike.

This book deals with the impact of uncertainty in input data on the outputs of mathematical models. Uncertain inputs as scalars, tensors, functions, or domain boundaries are considered. In practical terms, material parameters or constitutive laws, for instance, are uncertain, and quantities as local temperature, local mechanical stress, or local displacement are monitored. The goal of the worst scenario method is to extremize the quantity over the set of uncertain input data.
A general mathematical scheme of the worst scenario method, including approximation by finite element methods, is presented, and then applied to various state problems modeled by differential equations or variational inequalities: nonlinear heat flow, Timoshenko beam vibration and buckling, plate buckling, contact problems in elasticity and thermoelasticity with and without friction, and various models of plastic deformation, to list some of the topics. Dozens of examples, figures, and tables are included.
Although the book concentrates on the mathematical aspects of the subject, a substantial part is written in an accessible style and is devoted to various facets of uncertainty in modeling and to the state of the art techniques proposed to deal with uncertain input data.
A chapter on sensitivity analysis and on functional and convex analysis is included for the reader's convenience.
-Rigorous theory is established for the treatment of uncertainty in modeling
- Uncertainty is considered in complex models based on partial differential equations or variational inequalities
- Applications to nonlinear and linear problems with uncertain data are presented in detail: quasilinear steady heat flow, buckling of beams and plates, vibration of beams, frictional contact of bodies, several models of plastic deformation, and more
-Although emphasis is put on theoretical analysis and approximation techniques, numerical examples are also present
-Main ideas and approaches used today to handle uncertainties in modeling are described in an accessible form
-Fairly self-contained book

The editors invited selected authors who had participated in or observed developments in biochemistry and molecular biology, particularly in the second half of this century, to record their personal recollections of the times and circumstances in which they worked. Having been given free reign, both content and style of the contruibutions reflect the flavour of the personality of the author.

The book reflects the explosive development of biochemistry and molecular biology and related sciences that had led to the almost unique situation of these fields coming of age at a time when their founding fathers, or their scientific children, were alive and well.

The contributions in this volume encompass a wide variety of experiences in many different countries and in very different fields of biochemistry.

Scientists planning experiments in medical and behavioral research will find this handbook and dictionary an invaluable desk reference tool. Also recommended as a textbook for students of Experimental Design or accompanying courses in Statistics.

This two-part volume, a handbook of experimental design and a dictionary providing short explanations for many terms related to experimental design, contains information that will not quickly become outdated.

Due to the fundamental two-way interaction between the theoretical and the empirical aspects of monetary economics, together with the relationship of both to matters of public policy, any organization of material comprehensively spanning the subject is bound to be arbitrary. The 23 surveys commissioned for this Handbook have been arranged in a way that the editors feel reflects some of the most important logical divisions within the field and together they present a comprehensive account of the current state of the art. The Handbook is an indispensable reference work which should be part of every professional collection, and which makes ideal supplementary reading for graduate economics students on advanced courses.

The International Conference on Mechanical Design and Production has been established since 1979 by the Department of Mechanical Design and Production at Cairo University.

The conference MDP-6 held in Cairo, 2-4 January 1996, represents the 6th in the series. Its aim was to highlight the current advances in mechanical design and production, and to disseminate the latest developments from academic and industrial institutions in all related scientific disciplines.

This publication includes a selection of papers submitted to the conference and reviewed by members of the scientific committee. The main areas of the papers include: materials processing and characterization constitutive modeling; simulation and analysis of manufacturing processes; numerical analysis of structures; fracture analysis; design and tribology; dynamics, control and robotics; and new trends in industrial and manufacturing engineering.

This volume presents a review of the research in several areas of modern optics written by experts well-known in the international scientific community. The first chapter discusses properties and methods of production and detection of coherent superpositions of macroscopically distinguishable states of light (the so-called Schrodinger cat states). Chapter two deals with the phase-shift method, which originated in the 1930s, for the analysis of potential-scattering problems in atomic and nuclear physics. Recently this approach has been applied to wave propagation in one-dimensional inhomogeneous media. Chapter three is concerned with the statistical properties of dynamic laser speckles that arise from scattering objects with rough surfaces undergoing translation and rotation. A moving phase-screen model is employed, which gives a relatively simple formulation of the theory and a clear picture of the time-varying speckle phenomenon. The fourth chapter presents a review of the more important theoretical and experimental results relating to optics of multilayer systems with randomly rough boundaries. The significant theoretical approaches which make it possible to interpret experimental data involving such systems are described, and relevant methods for optical characterization of systems of this kind are outlined. The last chapter presents an account of a theory of the photon transport through turbid media.

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).

The book is restricted to linear equations and two particular problems (the time optimal problem, the norm optimal problem) which results in a more focused and concrete treatment. As experience shows, results on linear equations are the basis for the treatment of their semilinear counterparts, and techniques for the time and norm optimal problems can often be generalized to more general cost functionals.

The main object of this book is to be a state-of-the-art monograph on the theory of the time and norm optimal controls for y (t) = Ay(t) + u(t) that ends at the very latest frontier of research, with open problems and indications for future research.

Key features:

. Applications to optimal diffusion processes.
. Applications to optimal heat propagation processes.
. Modelling of optimal processes governed by partial
differential equations.
. Complete bibliography.
. Includes the latest research on the subject.
. Does not assume anything from the reader except
basic functional analysis.
. Accessible to researchers and advanced graduate
students alike
