Some articles on systems, system:
... Interoperability is the ability of diverse systems and organizations to work together (inter-operate) ... The term is often used in a technical systems engineering sense, or alternatively in a broad sense, taking into account social, political, and organizational ... While interoperability was initially defined for IT systems or services and only allows for information to be exchanged (see definition below), a more generic definition could ...
... Chaos theory studies the behavior of dynamical systems that are highly sensitive to initial conditions, an effect which is popularly referred to as the butterfly effect ... errors in numerical computation) yield widely diverging outcomes for such dynamical systems, rendering long-term prediction impossible in general ... This happens even though these systems are deterministic, meaning that their future behavior is fully determined by their initial conditions, with no random ...
... In the system studied, "Hadamard's billiards", Hadamard was able to show that all trajectories are unstable in that all particle trajectories diverge exponentially from one another, with a positive Lyapunov exponent ... evident for some scientists that linear theory, the prevailing system theory at that time, simply could not explain the observed behaviour of certain ... considered by chaos theories as a full component of the studied systems ...
... Linear dynamical systems can be solved in terms of simple functions and the behavior of all orbits classified ... In a linear system the phase space is the N-dimensional Euclidean space, so any point in phase space can be represented by a vector with N numbers ... The analysis of linear systems is possible because they satisfy a superposition principle if u(t) and w(t) satisfy the differential equation for the vector field (but not necessarily the initial condition), then so ...
... Chaotic behavior has been observed in the laboratory in a variety of systems, including electrical circuits, lasers, oscillating chemical reactions, fluid dynamics, and mechanical ... in weather, the dynamics of satellites in the solar system, the time evolution of the magnetic field of celestial bodies, population growth in ecology ... between quantum mechanics and classical mechanics works in the context of chaotic systems ...
Famous quotes containing the word systems:
“Before anything else, we need a new age of Enlightenment. Our present political systems must relinquish their claims on truth, justice and freedom and have to replace them with the search for truth, justice, freedom and reason.”
—Friedrich Dürrenmatt (1921–1990)
“We have done scant justice to the reasonableness of cannibalism. There are in fact so many and such excellent motives possible to it that mankind has never been able to fit all of them into one universal scheme, and has accordingly contrived various diverse and contradictory systems the better to display its virtues.”
—Ruth Benedict (1887–1948)
“The only people who treasure systems are those whom the whole truth evades, who want to catch it by the tail. A system is just like truth’s tail, but the truth is like a lizard. It will leave the tail in your hand and escape; it knows that it will soon grow another tail.”
—Ivan Sergeevich Turgenev (1818–1883)
