Therefore, he proposed a frequency domain transform in which the chosen bases may, under some mathematical constraints, change in amplitude and frequency as a function of time.
It is also able to detect non-stationary or chaotic signals (signals whose mathematical properties change randomly with time).
This was done for each emissions scenario by overlaying the 16 GCM departure maps and using the R statistical package command quantile to calculate the following ensemble quantile values at each grid cell: 0 (mathematical minimum projected change), 0.20, 0.40, 0.50 (median projected change), 0.6, 0.8, 1.0 (maximum projected change).
He creates mathematical models of changes of the heart's metabolism during heart failure.
There is, if not an actual mathematical sequence of changes, at least a principle of incessant variation underlying the whole corpus.
But physicist Christos Tsagas of Portsmouth University in the United Kingdom looked at the equation in an unusual way, switching the roles of space and time--a swap that makes no mathematical difference but changes the form of the equation.
In the former case, i.e. when (p(t)) represents spontaneous background noise and is modelled as a stochastic process, the mathematical background immediately changes to be stochastic analysis.
PRAM is a new method based on the objective mathematical analysis of changes of arterial pressure profile with time.
Nevertheless, mathematical modeling of changes in RNA levels predicts that mRNA degradation rate plays a pivotal role in shaping the kinetics of genes' response [ 10, 11].
Change and relations, i.e., mathematical representations of change over time as well as different types of relational and functional dependencies between mathematical objects.
