"It is a measure of Professor Samuelson's preeminence that the sheer scale of hiswork should be so much taken for granted," observes a reviewer in the Economist who goes on to notethat "a cynic might add that it would have been better for Professor Samuelson to write less merelyto give others a chance to write at all."In fact, Samuelson's output, his "extraordinary mastery ofmethods, both mathematical and linguistic" (review of Volume 4 of The Collected Scientific Papers),have not diminished. Volume 5 collects 108 articles written since 1976, bringing the total to nearly400 important contributions to economics. As in earlier volumes, the papers are arranged by subject.They cover Economic Theory: Marx, Keynes, and Schumpeter; International Economics; StochasticTheory; Classical Economics; Mathematical Biology; Biographical and Autobiographical Writings; andCurrent Economics and Policy.Volumes 1 through 4 encompass more than 280 articles. The first twocontain virtually all of Samuelson's contributions to economic theory through mid-1964; Volume 3contains all the scientific papers written from mid-1964 through 1970, and the last volume bringshis work up to through 1976.Paul Samuelson received the Nobel Prize in Economics in 1970 and isInstitute Professor of Economics Emeritus at MIT. Kate Crowley edited volume 4 of The CollectedScientific Papers with Hiroaki Nagatani.

A human observer is able to recognize the color of objects irrespective of the light used to illuminate them. This is called color constancy. A digital camera uses a sensor to measure the reflected light, meaning that the measured color at each pixel varies according to the color of the illuminant. Therefore, the resulting colors may not be the same as the colors that were perceived by the observer. Obtaining color constant descriptors from image pixels is not only important for digital photography, but also valuable for computer vision, color-based automatic object recognition, and color image processing in general. This book provides a comprehensive introduction to the field of color constancy, describing all the major color constancy algorithms, as well as presenting cutting edge research in the area of color image processing. Beginning with an in-depth look at the human visual system, Ebner goes on to: examine the theory of color image formation, color reproduction and different color spaces; discuss algorithms for color constancy under both uniform and non-uniform illuminants; describe methods for shadow removal and shadow attenuation in digital images; evaluate the various algorithms for object recognition and color constancy and compare this to data obtained from experimental psychology; set out the different algorithms as pseudo code in an appendix at the end of the book. Color Constancy is an ideal reference for practising engineers, computer scientists and researchers working in the area of digital color image processing. It may also be useful for biologists or scientists in general who are interested in computational theories of the visual brain and bio-inspired engineering systems.

First published in 2000. Routledge is an imprint of Taylor & Francis, an informa company.

This revised edition incorporates the latest discoveries in the rapidly changing fields of neuroscience and physiological psychology and offers the most comprehensive and integrative coverage of research and theory in contemporary behavioural neuroscience.

This fifteen-volume series collects the personal papers of Joseph Henry, who was the first secretary of the Smithsonian Institution, a founder of the American scientific community, and a pioneer experimental physicist in electricity in magnetism. The first five volumes were published under the editorship of Nathan Reingold.

The past decade has witnessed an increasing interest in observers for nonlinear systems. This subject is relevant in different contexts such as synchronization of complex dynamical systems, fault detection and isolation, and output feedback control. This book contains the contributions that are to be presented at the workshop "New Directions in Nonlinear Observer Design", to be held from June 24-26, 1999, in Geiranger Fjord, Norway. The workshop has been organised by Olav Egeland, Thor I. Fossen and Henk Nijmeijer; it will include participants from Africa, Asia, Europe and USA and it will focus on recent developments in the above mentioned areas. The contributions form a good review of present achievements and challenges in nonlinear observer design. The workshop is supported by the Strategic University Program on Marine Cybernetics at the Norwegian University of Science and Technology and ABB.
