These include lists of mutations relevant for drug resistance, rule-based algorithms, and mathematical models based on correlations found in databases containing genotypes and drug susceptibility data [ 4, 9- 15].
A mission called NEOWISE translates this heat data into size estimates using empirical models — mathematical models based on things that scientists have observed about individual asteroids.
Mathematical models based on energy analysis of some configurations of solar air heater have been discussed.
The results were employed to design non-linear mathematical models based on artificial neural networks.
Three mathematical models based on the effects due to particles, light sources and diffraction are discussed.
"For too long economists have neglected the distribution of wealth, partly because of the profession's undue enthusiasm for simplistic mathematical models based on so-called representative agents," he says.
The new ontology provides a means for automating the creation of mathematical models based on operations research principles.
These include game-theoretic models based on the "prisoner's dilemma" (PD), dynamic mathematical models based on the Richardson model, and economic models frequently based on a "utility-maximizing" framework.
And while colleges have elaborate mathematical models, based on past experience, to tell them how many seniors they need to admit to assemble the size of the incoming class they desire, this year many admissions deans are concerned that the surge in applications by the most competitive seniors may throw off their projections.
"Brasseur's mathematical models based on these M.R.I. images are useful to understand physiological problems that we can't readily understand in any other way," said Dr. Peter J. Kahrilas, chief of the division of gastroenterology at Northwestern University's Feinberg School of Medicine, who is working with Dr. Brasseur on research on the esophagus.
In a manifesto published in April economics students at the University of Manchester advocated an approach "that begins with economic phenomena and then gives students a toolkit to evaluate how well different perspectives can explain it", rather than with mathematical models based on unreal assumptions.
