Mathematical models of wind turbine blade aerodynamics have provided valuable limits on the performance for actual wind turbines. The simplest and best known is the Betz limit on power production. It is less well-known that this limit applies only at...

Many studies have shown that the most important factor in investment success is asset allocation, as opposed to stock picking. At its most basic level, this amounts to the choice of how much to allocate to bonds and stocks.In this talk, I will...

A video of this event is available on mathtube.org. Wavelets have been successfully applied to many areas. For high-dimensional problems such as image/video processing, separable wavelets are widely used but are known to have some shortcomings such...

It is typically used to study evolutionary scenarios in low-dimensional phenotype spaces, such as the important phenomenon of evolutionary branching (adaptive diversification). I will briefly recall the basic theory of evolutionary branching and...

Dennis Gabor was a Hungarian/British physicist who invented holography, for which he received the 1971 Nobel Prize. However, in the world of seismic data analysis, he is best known for the Gabor transform, a special case of the short-time Fourier...

Real stable polynomials define real hypersurfaces with special topological structure. These polynomials bound the feasible regions of semidefinite programs and appear in many areas of mathematics, including optimization, combinatorics and...

Pierre-Simon marquis de Laplace in his 5 volume Traité de mécanique céleste unified mathematical physics by placing calculus front and center. Among Laplace's chief innovations, was an introduction of a differential equation that now bears his name...

We apply a general framework to analyze the influence of system load on service times in queueing systems to EMS systems. The framework unifies previous results and ties them to possible future studies to help empirical and analytical researchers to...

In this talk I will explain basic ideas concerning fractional Laplacians (in particular, their relation with Lévy flights in Probability) and I will present the essential tools to treat nonlinear equations involving fractional Laplacians and other...

How does mathematical knowledge grow? According to an influential formulation due to philosopher Ernest Nagel, when a scientific theory "reduces" another, the reduced theory is deductively subsumed under the reducing theory: thus for example...
