Sentences with phrase «using dynamical systems»

«The idea behind using dynamical systems for computation is to build a machine such that its dynamics — which has to do with the structure of the machine or the structure of the math — will lead it to the answer based on feeding it the question,» said Rothganger, a computer scientist.

Images of simulated lenses, as well as real images which lack lenses, are inserted into the image stream at random intervals; this training set is used to give the volunteers instantaneous feedback on their performance, as well as to calibrate a model of the system that provides dynamical updates to the probability that a classified image contains a lens.

Four years later, another team of astronomers using the 2.5 - meter Isaac Newton Telescope at Roque de los Muchachos Observatory on La Palma (and relying on evidence supplied by their own dynamical models of Sagittarius and on preliminary results from the international Sloan Digital Sky Survey team) announced that they had found an excess of young stars belonging to a stellar system located at 183,000 ly (56,000 pc) from the center of the Milky Way.

Although there are extreme limitations on what is known about potential tipping points the new paradigm does provide an opportunity to reframe the climate wars — clearly that nearly everyone has been dead wrong about the essential nature of Earth systems using simple causality rather then dynamical complexity.

We have used the Grid ENabled Integrated Earth system modelling (GENIE) framework to undertake a systematic search for bi-stability of the ocean thermohaline circulation (THC) for different surface grids and resolutions of 3 - D ocean (GOLDSTEIN) under a 3 - D dynamical atmosphere model (IGCM).

Also the behaviour of our numerical simulations of the atmosphere would continue to be affected by the problems typical of model simulations of chaotic dynamical systems even if we could have perfect initial conditions, write perfectly accurate evolution equations and solve them with perfect numerical schemes, just because of the limited number of significant digits used by any computer (Lorenz, 1963).

The emergence of dissipative structures such as the AO is the relevant metric in both the analysis and forecasting (within its temporal limits) dynamical systems and not proportionate forcing response arguments used by primitive tribes eg Ruzmaiken.

A tipping point as Sornette used it refers to a chaotic bifurcation in complex dynamical systems.

It looks like a complex dynamical system that has numerous manifestations that we know of — as in the diverse examples of Sornette — therefore it has these properties that may make analysis tractable but in a different sense than we are used to.

Our approach is anchored in statistical analysis of time - series datasets using models of growth and diffusion, particularly Lotka - Volterra dynamical systems.

It appears to me, caveat as above, that AGW has created a lifeless system in thinking in this «energy balance» much as it has done with CO2 with its destruction of the dynamical system which is all life by thinking of plants merely as «carbon sinks», somewhere merely to store CO2; from which the used to be known fact that CO2 was food for all living carbon life forms is practically unknown and now at the absurd reasoning from not knowing it, that it can defy gravity and stay removed and out of reach from the carbon life forms which evolved from its property of being available at ground level.

But the mathematical analysis of the frequencies, the demonstrations of the problems with the continuum systems using convergent numerical solutions on the Exponential thread, and the dynamical core manuscript itself should make the issues very clear.

Please keep unrelated questions on other issues (such as forced atmospheric models or full climate models) off of this thread so that this manuscript can be used to illuminate the serious and unresolvable problems with numerical approximations of the unforced dynamical systems.
