2015 Reprint of 1956 Printing. Full facsimile of the original edition. Not reproduced with Optical Recognition Software. Cybernetics is here defined as "the science of control and communication, in the animal and the machine"-in a word, as the art of steersmanship; and this book will interest all who are interested in cybernetics, communication theory and methods for regulation and control. W. Ross Ashby (1903-1972) was an English psychiatrist and a pioneer in cybernetics, the study of complex systems. His two books, "Design for a Brain" and "An Introduction to Cybernetics," were landmark works. They introduced exact and logical thinking into the nascent discipline and were highly influential. Contents include: What is new -- Change -- The Determinate Machine -- The Machine with Input -- Stability -- The Black Box -- Quantity of Variety -- Transmission of Variety -- Incessant Transmission -- Regulation in Biological Systems -- Requisite Variety -- The Error-controlled Regulator -- Regulating the Very Large System -- Amplifying Regulation

The Statistical Analysis of Spatial Pattern (Ettore Majorana International Science Series)

In a contribution (Bartlett, 1971 a) to the Symposium on Statistical Ecology at Yale in 1969, I noted in my introductory remarks that that paper was not intended to be in any way a review of statistical techniques for analysing spatial patterns. My contribution to a conference at Sheffield in 1973 aimed, at least in part, to supply such a review and forms the basis of this monograph; but in these prefatory remarks I must still make clear what I decided to discuss, and what I have omitted. Broadly speaking, the coverage is that included in seminars and lectures I have given on this theme since 1969. We may divide problems of spatial pattern (in contrast with complete random chaos) into (i) detecting departures from randomness, Oi) analysing such departures when detected, for example, in relation to some stochastic model and (iii) special problems which require separate consideration; for example, sophisticated problems of pattern recognition in specific fields, such as the computer reading of handwriting or recognition of chromosomes.

Linear Estimation and Stochastic Control (Chapman & Hall Mathematics Series)

Davis, M.H.A.

This book provides a systematic review of tomographic applications in seismology and the future directions. Theories and case histories are discussed by the international authors, drawing on their own practical experiences with global and local case histories.

This collection of six essays centers on Professor Koyre's great the relative importance of metaphysics and observation, with controlled experiment a kind of marriage between the two. Professor Koyre's thesis might be summed up as a claim that when one is seeking to explain the scientific revolution, attention must be concentrated on the philosophical outlook of the scientist and away from speculative theories.At the time of his death, Alexandre Koyre was a professor at the Ecole Pratique des Hautes Etudes (Sorbonne) and a memeber of the Institute for Advanced Study in Princeton.

The subject of power electronics originated in the early part of the twentieth century with the development and application of devices such as the mercury arc rectifier and the thyratron valve. Indeed many of the circuits currently in use and described in this book were developed in that period. However, the range of applications for these early devices tended to be restricted by virtue of their size and problems of reliability and control. With the development of power semiconductor devices, offering high reliability in a relatively compact form, power electronics began to expand its range and scope, with applications such as DC motor control and power supplies taking the lead. Initially, power semiconductor devices were available with only relatively low power levels and switching speeds. However, developments in device technology resulted in a rapid improvement in performance, accompanied by a corresponding increase in applications. These now range from power supplies using a single transistor to high voltage DC transmission where the mercury arc valve was replaced in the 1970s by a solid-state 'valve' using thyristor stacks. Developments in microprocessor technology have also influenced the develop ment of power electronics. This is particularly apparent in the areas of control, where analogue controllers are being replaced by digital systems, and in the evolution of the 'smart power' devices. These developments have in turn led to system improvements in areas such as robot drives, power supplies and railway traction systems.
