	Dissipation - Wikipedia, the free encyclopedia
		In physics, dissipation embodies the concept of a dynamical system where important mechanical modes, such as waves or oscillations, lose energy over time, typically due to the action of friction or turbulence.
		The precise nature of the effects depends on the nature of the wave: an atmospheric wave, for instance, may dissipate close to the surface due to friction with the land mass, and at higher levels due to radiative cooling.
		A formal, mathematical definition of dissipation, as commonly used in the mathematical study of measure-preserving dynamical systems, is given in the article wandering set.

	Dissipative system - Wikipedia, the free encyclopedia
		A dissipative system (or dissipative structure) is an open system which is operating far from thermodynamic equilibrium within an environment that exchanges energy, matter or entropy.
		A dissipative system is characterized by the spontaneous appearance of a complex, sometimes chaotic, structure.
		A formal, mathematical definition of a dissipative system as the action of a group on a measurable set is given in the article on wandering sets.

		All systems that exhibit disequilibrium and self-organization are dissipative and have a dissipative structure (Briggs and Peat, 1989, p.
		Dissipative structures are those which are able to maintain identity only because they are open to flows of energy, matter, or information from their environments (Prigogine and Stengers, 1984).
		Dissipative systems operate in a phase space, much like conservative systems, but usually have an infinite number of dimensions in which the various properties are distributed in space.

	Fisika & Psichica
		Dissipative systems are those which are able to maintain identity only because they are open to flows of energy, matter, or information from their environments (Prigogine and Stengers, 1984).
		A dissipative structure refers to the structure of an open system in which energy is added to the system in order to decrease entropy and maintain stability (Prigogine and Stengers, 1984, p.
		A bifurcation is a crisis point in the life of a system, in which the future of that system is uncertain.

	Conservation Ecology: Infodynamics, a developmental framework for ecology/economics
		Dissipative structures do the same by degrading energy gradients during growth and homeostasis in such a way as to produce entropy to an extent that is correlated with the rate at which they dissipate the gradients.
		Consequently, systems grow because they are linked to energy gradients in such a way that some of the energy, i.e., the exergy, in those gradients is transferred to these systems when they harness the resulting energy flow during their formation.
		This system resilience is the tactic an ecosystem uses to escape from senescence and is comparable to the organism's tactic of reproduction and death.

	Human Brain & Psyche
		All systems that exhibit disequilibrium and self-organization are dissipative and have a dissipative structure (Briggs and Peat, 1989).
		Systems damped by friction, and driven by some kind of energy input, while appearing to be at an equilibrium state, are not really at equilibrium at all.
		For open systems, where the entropy change due to the environment is sufficiently negative that it exceeds the magnitude of the internal entropy of the system, then entropy will decrease (order will increase) over time during the process.

	Autopoiesis (Site not responding. Last check: 2007-10-08)
		Ilya Prigogine's theory of dissipative structures explained how living systems maintain their order - their stable structure - in the face of a constant flux of matter and energy passing through them by dissipating entropy to their environment.
		Prigogine's theory of dissipative structures redirected the science of thermodynamics from linear, equilibrium systems (which are extremely boring) to nonlinear, non-equilibrium systems (of which you are one).
		In complexity,life is as an emergent property of a system.

	Quantum Brain
		Dissipative quantum dynamics of the brain: In this section the quantum model of the brain proposed by Ricciardi and Umezawa is extended to dissipative dynamics by resorting to some results on dissipative systems in QFT[2,27,28].

		Dissipation, which is intrinsic to the brain dynamics, is recognized to be the root of such a complexity, namely of the huge memory capacity.

	M.Schwartz: Chaotic Systems and Blake's Mythology (Site not responding. Last check: 2007-10-08)
		As with other chaotic systems, dissipative structures derive an internal order from their instability, and it is by means of their constant lapsing into disorder and rebounding into organization that they "evolve," proceeding toward some unimaginably complicated yet structured end, despite the efforts of the supposedly-dominant force of entropy.
		The dissipation of energy produces not entropic chaos or heat-death but order, as evolution brings life forms to a more ordered state rather than a more homogeneous one, and an influx of outside influences is required for the system to evolve.
		Dissipative structures must also, according to Prigogine, "fluctuate nonlinearly." "That is, the amount of energy, matter, and information they contain at any future moment will be unpredictable (they follow nonlinear differential equations that are usually difficult to solve and which describe behaviors impossible to predict)" (Porush 290).

		Dissipative systems are recognized in complexity and chaos theory as important examples of systems involving complicated yet deterministic interaction between agents.
		Dissipative systems are open to environmental influences and undergo real change and restructuring based on inherent stabilites.
		He elaborated:...provided the laws which govern a chaotic system are known, the greater the temporal distance between initial (and intervening) conditions on the one hand and the event to be explained on the other, the greater the accuracy with which those conditions must be known.

		A Hamiltonian system is conservative: certain physical properties of the system remain constant in time.
		And unlike Hamiltonian systems, for a dissipative system the phase space volume does not remain constant as the system develops in time.
		As the dissipative system evolves in time, the trajectory in phase space heads for some final phase space point, curve or a fractal region: an attractor of the system.

	Sustainability through the Dynamics of Strategic Dilemmas: in the light of the coherence and visual form of the ...
		Dissipative systems, and the M-set, offer a language through which to explore and identify viable patterns of sustainable relationship between essentially incompatible modes of behaviour or anti-thetical modes of thinking.
		A dissipative system is when there are two different orders or ordering mechanisms that are out of balance with each other so that one ordering mechanism is disordering the other and creating a boundary between the two ordering mechanisms where one is dominant and the other is being dominated.
		Dissipative systems have an interface between their two orderings (that of the system and that of the environment) which is very complicated.

	Citebase - Exact Dynamics of Quantum Dissipative System in Constant External Field
		Authors: P, C. Yu, L. The quantum dynamics of a simplest dissipative system, a particle moving in a constant external field, is exactly studied by taking into account its interaction with a bath of Ohmic spectral density.
		Quantizing the dissipative system we obtain the simple and exact solutions for the coordinate operator of the system in Heisenberg picture and the wave function of the composite system of system and bath in Schroedinger picture.
		An effective Hamiltonian for the dissipative system is explicitly derived from these solutions with Heisenberg picture method and thereby the meaning of the wavefunction governed by it is clarified by analyzing the effect of the Brownian motion.

	Levels of Major Complexity
		In the natural world, galaxies, star systems with planets, and the earth are the most readily observable examples of massive dissipative structures with multiple levels of complexity.
		There are also higher-level dissipative structures that have been hypothesized, such as Gaia [12], Hypersea (``organismal entity'' that extended life onto land) [13], and Metaman (global mankind with electronic communication as ``organismal entity'') [19] that will be useful in understanding the evolution of complexity.
