Cybernetics is the transdisciplinary study of circular processes such as feedback systems where outputs are also inputs. It is concerned with general principles that are relevant across multiple contexts, [1] including in ecological, technological, economic, biological, cognitive and social systems and also in practical activities such as designing, [2] learning, and managing.
The opening passage illustrates the effect of faulty feedback mechanisms by the example of patients with various forms of ataxia. He then discusses railway signalling, the operation of a thermostat, and a steam engine centrifugal governor. The rest of the chapter is mostly taken up with the development of a mathematical formulation of the ...
The word cybernetics refers to the theory of message transmission among people and machines. The thesis of the book is that: society can only be understood through a study of the messages and the communication facilities which belong to it; and that in the future development of these messages and communication facilities, messages between man and machines, between machines and man, and between ...
A cyborg (/ ˈ s aɪ b ɔːr ɡ /) (also known as cybernetic organism, cyber-organism, cyber-organic being, cybernetically enhanced organism, cybernetically augmented organism, technorganic being, techno-organic being, or techno-organism)—a portmanteau of cybernetic and organism—is a being with both organic and biomechatronic body parts.
Cybernetical physics is a scientific area on the border of cybernetics and physics which studies physical systems with cybernetical methods. Cybernetical methods are understood as methods developed within control theory, information theory, systems theory and related areas: control design, estimation, identification, optimization, pattern recognition, signal processing, image processing, etc ...
Biorobotics is an interdisciplinary science that combines the fields of biomedical engineering, cybernetics, and robotics to develop new technologies that integrate biology with mechanical systems to develop more efficient communication, alter genetic information, and create machines that imitate biological systems.
Computational cybernetics is the integration of cybernetics and computational intelligence techniques. Though the term Cybernetics entered the technical lexicon in the 1940s and 1950s, it was first used informally as a popular noun in the 1960s, when it became associated with computers , robotics , Artificial Intelligence and Science fiction .
For example, a machine with states {,,,} has a variety of four states or two bits. The variety of a sequence or multiset is the number of distinct symbols in it. For example, the sequence ,,,,, has a variety of four.
