Sentences with phrase «occurs in the simpler models»

Not exact matches

But it need not be so, if we begin to see how the imagination can create models and metaphors, can use logically odd qualifiers, can present ideas in poetic - simple language, so that new onlooks may occur.

The researchers reduced this complex model to a much simpler, «textbook» model, which predicts that a phase transition, or a change in flow direction, should occur with certain changes to a lattice's dimensions — a transition that the team observed in their experiments with bacteria.

Predicting if flutter occurs, for a given flexible object in a given fluid flow, is typically not the problem; simple mathematical models can often accomplish this.

The double pulsar PSR J0737 — 3039A / B consists of two neutron stars in a highly relativistic orbit that displays a roughly 30 - second eclipse when pulsar A passes behind pulsar B. Describing this eclipse of pulsar A as due to absorption occurring in the magnetosphere of pulsar B, we successfully used a simple geometric model to characterize the observed changing eclipse morphology and to measure the relativistic precession of pulsar B's spin axis around the total orbital angular momentum.

As a whole, now the conceptual transition occurs from proving the inflationary paradigm in general and testing some of its simplest models to applying it for investigation of particle physics at super-high energies and of the actual history of the Universe in the remote past using observational data.

Simple models are very different, and are more like an effective sensitivity and may well lack some of the nonlinear dynamics / regional processes that occur in the real world and, in a more limited way, in the complex models.

If you just model a 1X and 2X in excel over time, you'll see why the value decay occurs; it's simple mathematics.

One example is the THC «shutdown», which was «predicted» by simpler models, but tends not to occur in the more sophisticated models, coupled AOGCMs.

Some of them are optimal fingerprint detection studies (estimating the magnitude of fingerprints for different external forcing factors in observations, and determining how likely such patterns could have occurred in observations by chance, and how likely they could be confused with climate response to other influences, using a statistically optimal metric), some of them use simpler methods, such as comparisons between data and climate model simulations with and without greenhouse gas increases / anthropogenic forcing, and some are even based only on observations.

Because these types of distortions impose societal costs beyond those of a simple carbon tax, the economic impacts modeled here will, if anything, be lower than would actually occur in a regulatory scheme.

Within economics modelling, attempts to model the feedback mechanisms that occur in the real economy are also really difficult — we know, for example, that investment in new technologies will act as an incentive for the existing technologies it hopes to substitute to become more efficient (the sailing ship effect — i.e. in the 50 years after the introduction of the steam ship, sailing ships made more efficiency improvements than they had in the previous 3 centuries) but how to quantify something even as simple as this is not easy BUT we have learnt a few ways to give sensible (order of magnitude) figures with time lags, the learning by doing effect and phased - in substitution effects based on massive amounts of data.

So it seems to me that the simple way of communicating a complex problem has led to several fallacies becoming fixed in the discussions of the real problem; (1) the Earth is a black body, (2) with no materials either surrounding the systems or in the systems, (3) in radiative energy transport equilibrium, (4) response is chaotic solely based on extremely rough appeal to temporal - based chaotic response, (5) but at the same time exhibits trends, (6) but at the same time averages of chaotic response are not chaotic, (7) the mathematical model is a boundary value problem yet it is solved in the time domain, (8) absolutely all that matters is the incoming radiative energy at the TOA and the outgoing radiative energy at the Earth's surface, (9) all the physical phenomena and processes that are occurring between the TOA and the surface along with all the materials within the subsystems can be ignored, (10) including all other activities of human kind save for our contributions of CO2 to the atmosphere, (11) neglecting to mention that if these were true there would be no problem yet we continue to expend time and money working on the problem.

The small thermal energy extractions that occur in the OTEC plant are neglected so temperature and salinity characteristics in the effluent are determined from simple mixing models.

Simple models are very different, and are more like an effective sensitivity and may well lack some of the nonlinear dynamics / regional processes that occur in the real world and, in a more limited way, in the complex models.

We show that this occurs in spite of a decline in radiative forcing that exceeds the decline in ocean heat uptake — a circumstance that would otherwise be expected to lead to a decline in global temperature when using the simple energy balance model described in the post.
