Description Work with T. Bielecki, Y. LeCam , M Rutkowski We study the different models of credit risk and we present some cases where the hazard process approach is more efficient than the intensity...
Description Archimedean copulas have proven to be remarkably useful for modeling dependence in a variety of settings. In this talk we will survey important aspects of the theory of Archimedean copulas...
Speaker Joe Tribbia Institute for Mathematics Applied to Geosciences, NCAR http://www.cgd.ucar.edu/cdp/gdsstaffwebs/tribbia.htm Description The problem of predicting the future state of the weather...
Description Visual stimuli produce waves of activity in the visual cortex of freshwater turtles. The waves can be visualized using modern imaging methods and have complicated spatiotemporal dynamics...
Description We investigate the nonlinear dynamics of subcritical instabilities in the presence of a feedback control. The control is based on a feedback loop between the linear growth rate and the...
Description An appropriate image representation induces some good picture treatment algorithms. Hypergraph theory is a theory of finite combinatorial sets, modeling many problems of operational...
Description In this presentation we define a 2D and 3D-image representation based on a hypergraph of rectangle. This representation conducts to a lossless compression algorithm for 2D and 3D-images...
