Mads Stehr

During his PhD studies, Mads Stehr has investigated different questions related to 1) the estimation of volume, and 2) spatial and temporal stochastic systems.

For instance, he has investigated how to estimate the integral of a function, which is known at a sequence of points with unequal mutual distances. This corresponds to the estimation of the volume of a 3-dimensional object from area measurements in parallel section profiles. However, it is of great mathematical interest in itself. The research shows that a newly suggested estimation procedure has improved precision compared to the existing methods. 

Furthermore, Mads Stehr has considered so-called extremal events for a class of space- and time-dependent stochastic systems known as Lévy-driven fields. As an example, he has characterized the probability that there is a location in space and time such that the system attains a given large value. This could for instance correspond to the examination of whether rain of a given magnitude will occur somewhere in a bounded land area within a fixed time horizon.

The PhD study was completed at the Department of Mathematics, Faculty of Natural Sciences, Aarhus University.

This summary was prepared by the PhD student.
