The computer was an extension of his well - known Difference Engine, which was designed to calculate tables of numbers such as logarithms.
(A) Genome - wide distribution of heterozygosity estimates for genomic tracks, calculated as the logarithm of the Watterson estimators, averaged across the track and weighted by its length.
The radiative forcing generated by CO2 change goes as the logarithm of the concentration, and thus removing the whole CO2 inventory would generate a much larger impact than had you doubled it.
This has the asymptotic behavior of appearing as a logarithm for large x and as a linear function for small x.
Since the UHI increases as the logarithm of the population...»
If the UHI only grows as the logarithm of the population, that could go a long way to explaining why Parker doesn't see any UHI trend.
It is generally accepted that the warming effect from CO2 increases roughly as the logarithm of CO2 concentration.
Optical Depth or Optical Thickness The parameter of a transparent layer of gases or particles defined as the logarithm of the ratio between incident and transmitted radiative flux.

Not exact matches

For example, the classical equations used to predict the performance of such materials have indicated that the logarithm of the reaction rate should vary linearly as voltage is increased — but experiments have shown a nonlinear response, with the uptake of lithium flattening out at high voltage.
That means defining familiar operations — such as addition, subtraction, multiplication, division, exponentiation, logarithms, and so on — so that they work as well for surreal numbers as they do for the usual reals.
We used the standard error of the logarithm of the relative risk, or the number of events if the standard error was unavailable, as weights in the regression; if both were unavailable, we did an unweighted log - linear regression for the study.
For consumption, we used the midpoint of the reported number of cigarettes per day — for example, three cigarettes per day if the category was one to five cigarettes per day — which we then adjusted for carboxyhaemoglobin and cotinine because this allows for lower inhalation with increasing cigarette consumption as previously established.14 For studies that reported relative risks adjusted for age (or for additional factors), the model contained the logarithm of the relative risk (dependent variable) and consumption (independent variable) using only the midpoint of the cigarettes per day categories.
Scientific logarithm is used to ensure that the matches are as accurate as possible.
Yet Common Core's «college readiness» definition omits content typically considered part of algebra 2 (and geometry), such as complex numbers, vectors, trigonometry, polynomial identities, the Binomial Theorem, logarithms, logarithmic and exponential functions, composite and inverse functions, matrices, ellipses and hyperbolae, and a few more.
Most elegantly, if the natural logarithm is used, yielding the neper as logarithmic units, scaling by 100 to obtain the centineper yields units that are infinitesimally equal to percentage change (hence approximately equal for small values), and for which the linear equations hold for all values.
The optical depth, TAU, can also be expressed as the negative of the logarithm of the transmission, i.e., TAU = — log [exp -LRB--- TAU)-RSB-.
The reaction increases seawater acidity and increases the hydrogen ion activity, thus lowering seawater pH. pH is defined as the negative logarithm of the hydrogen ion activity, so that a 1 - unit change in pH is equivalent to a 10-fold change in H +.
If you said 4, you are correct, as that is the 11th digit in the base of Napierian logarithms, e.
Here's the logarithm of the wavelet power (using the WWZ, or «weighted wavelet Z - transform») as a function of time and frequency (NOTE: in this graph, unlike those preceding, time goes from right to left so the present day is at the far left):

For instance, if we regress global temperature as a function of time, and of the logarithm of population, then we find that those two predictors are strongly correlated.
As an insulator, CO2 provides a thickness that is proportional to the logarithm of the amount of CO2 which is why global warming is not much of a threat.
In the data above, the R ^ 2 (a measure of correlation) between the temperature and the CO2 is 0.68... but the R ^ 2 between the temperature and the logarithm of CO2, rather than being better as we'd expect if CO2 were actually driving temperature, is marginally worse for the logarithmic relationship (0.67) than the linear.
And no, leaving out the binary logarithm is not a typo, as subsequent calculations show.
He also probably confirmed, by laboratory experiment, that the heat absorption of CO2 increases by a logarithm function as the concentration increases.
Optical depth, or optical thickness is a measure of transparency, and is defined as the negative logarithm of the fraction of radiation (e.g., light) that is not scattered or absorbed on a path.
