Sentences with phrase «exponential decay»
Exponential decay refers to the gradual decrease of something over time, but the rate of decrease becomes faster and faster. It can be thought of as a snowball rolling down a hill and getting bigger as it gathers more snow, but when it starts to melt, it shrinks rapidly. Full definition

Powerpoint covering the definition of half - life, an animated graph showing exponential decay, another graph for students to use to calculate half - life.
Shock breakout is followed by a long «plateau» phase of almost constant luminosity lasting several months, before a slow exponential decay.
The purpose of most of these currencies is to offer small modifications from Bitcoin proper, including faster confirmation times, attempts at socially useful mining algorithms and different monetary policies such as fast exponential decay, quadratic decay and even infinitely linearly growing supply, and investors and users of the coins believe that these additional features and modifications will make the currencies either overtake Bitcoin or at least survive in some niche.
Artist's conception of evolution of metal - poor and «metal - rich» supernovae at different phases and simulated light curves from shock breakout (ultraviolet) through plateau (red, green and blue colors) to exponential decay.
Students compare linear and exponential decay, as well as explore how various products have depreciated and what might account for those differences.
Math concepts include formulas, decimals, percentages, exponential decay, and linear relationships.
Since we are sellers of calls, we capture the exponential decay by selling near - term calls.
The weights on squared deviations from the mean (for the standard deviation computation) follow an exponential decay process with a half - life of 5 years, so that the most recent data point has twice the weight in the volatility estimate as 5 years ago, which has twice the weight as 10 years ago, and so on.
The exponential decay - weighted volatility estimates function as an approximation of current volatility, which is our best estimate for forward - looking volatility.
The frequency of streaks seems to follow an exponential decay pattern that is essentially coin - flip random, decaying at a rate of around 50 %.
Again, there is exponential decay of streaks, near coin flip levels here as well.
In physics, the term «half - life» references the exponential decay of matter, or the time it takes for something to fall to half it's value.
The response lags behind the exponential decay for when all the heat capacities are immediately accessible to the surface after somewhere between 600 and 700 years.
When graphed over the logarithm of time (where the exponential decay to equilibrium looks like an S curve), T (0)'s approach to equilibrium may be approximated by two linear segments (after year 0.5 or 1), the first going to about 76 % of equilibrium response around year 70, and the second getting to near 99 % sometime around 4000 years (graphically estimated).
This is inherent in the nature of exponential decay.
«It follows an exponential decay pattern, losing a constant percentage every year,» explained O'Hare.
Gloor et al (2010)-LRB--RRB- estimate a half life of ~ 30 years for CO2, and find an exponential decay model with unvarying time constant fits the data.
Thus $ \ tau < 0 $ in this case, and we are dealing with exponential growth of the temperature anomaly rather than exponential decay.
