Motivated by the need to properly address near-term (i.e. interannual to interdecadal) climate prediction as an initial-value problem, intense interest has emerged on the development of data assimilation for coupled atmosphere--ocean global climate models. Basic research on this problem is challenging due to the large computational expense assoc...

A n-sided polygon in 3-space can be described as a point in 3n-space by listing in order the coordinates of it vertices. In this way, the space of embedded n-sided polygons is a manifold in which points correspond to piecewise linear knots and paths correspond to isotopies which preserve the geometric structure of these knots. In this talk, we w...

This talk will focus on theory and practice of combinatorial auctions and their application to thesale of wireless spectrum licenses. As new wireless applications emerge worldwide, the wireless industry and government regulators are looking to reallocate wireless spectrum to better match the demand. Combinatorial auctions can play an effective r...

The classical way of measuring the regularity of a function is by comparing itin the neighbourhood of any point with a polynomial of sufficiently high degree.Would it be possible to replace monomials by functions with less regular behaviouror even by distributions? It turns out that the answer to this question hassurprisingly far-reaching conseq...

I will explain the concept of transit-time distributions (TTDs) todiagnose passive tracer transport in geophysical fluids, like theEarth's ocean and atmosphere. The TTD is directly related to the Green'sfunction to the advection/diffusion equation for the concentration of adynamically-passive trace substance. Diagnosing and interpreting theTTD, ...

This talk deals with optimal harvesting strategies for the predator in a predator-prey system. The objective function is of long-run average per unit time type in the path-wise sense.The ecological system is subject to environmental noise modeled as stochastic differential equations driven by a Brownian motion. The main result is to prove the ex...

Tate Haglund-Pagel shares his experiences of living during the COVID-19 pandemic. As an educator who is an instructional technology integration coach, he talks briefly about his work in the school system on the day students and teachers were sent home last spring. He says working from home is a mixed blessing; there have been some additional str...

Amber Haglund-Pagel shares her experiences of life during the time of the COVID-19 pandemic. As the Safety and Training Officer for the city of Duluth, Amber recalls that very early in the pandemic Duluth secured enough personal protective equipment for the fire and police departments but she recalls just how little was known and how “unnerving”...

We shall present a new qualitative imaging method capable of identifying defects in unknown backgrounds from differential measures of farfieldoperators: i.e. far measurements of scattered waves in the configurations with and without defects. Indeed, the main difficulty is that the background physical properties and geometry are unknown. Our appr...
