Hypergraph-based Image Representation

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...

Hypergraphs for 2D and 3D Lossless Image Compression

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...

Viscoelasticity, Stochasticity, Non-Equilibrium Thermodynamics, and Non-Newtonian Fluid Mechanics

Boundary layers associated with the incompressible Navier-Stokes equations:The non characteristic case

Description In this lecture, we will study the behavior for small viscosity of the Navier-Stokes equations in a channel when the walls are permeable (noncharacteristic case). Convergence is proved to...

Hedging of Credit Derivatives in Models with Totally Unexpected Default

Description The paper presents an overview of methods of hedging defaultable derivatives under the assumption that there exist tradeable assets with dynamics allowing for elimination of default risk...

Generalized Interpolation with Applications

Adaptive Poisson Disorder Problem

SpeakerErhan BayraktarUniversity of Michiganhttp://www.math.lsa.umich.edu/~erhan/ Description We study the quickest detection problem of a sudden change in the arrival rate of a Poisson process from a...

Large Deviations for Markov Processes and Related Variational Problems

Description Large deviation estimates are probabilistic limit theorems which are used to describe atypical behavior of random systems. Markov processes are a rich class of probabilistic models. Their...

A Geometric Method for Automatic Extraction of Sulcal Fundi

Description Sulcal fundi are 3D curves that lie in the depths of the cerebral cortex and are often used as landmarks for downstream computations in brain image processing. In this talk, a sequence of...

Computing Accurate Eigenvalues of Structured and Random Matrices

SpeakerPlamen KoevMassachusetts Institute of Technologyhttp://www-math.mit.edu/~plamen/ Description Biologists often face the following problem: Given a set of taxa and information about them-which...
