TOPOLOGY/ GEOMETRY SEMINAR
TITLE: Coarse spaces vs coarse proximity spaces II
SPEAKER: Pawel Grzegrzolka, University of Tennessee
TIME: 3:35 PM-4:25 PM
ROOM: Ayres 406
In this talk, we will investigate the relationships between coarse spaces and coarse proximity spaces. After reviewing the necessary definitions, we will discuss normality conditions of spaces capturing large-scale properties of spaces. Then, we will use a characterization of coarse proximities in terms of coarse neighborhoods to show that (under mild assumptions) coarse space structures naturally induce coarse proximity structures. Time permitting, we will alsoshow the converse of the above statement. This is joint work with Jeremy Siegert.
TITLE: Asymptotics for Brownian motion in Poisson potential with Riesz kernel and in time-independent Gaussian rough noise
SPEAKER: Bo Gao, University of Tennessee
TIME: 4:00 PM
ROOM: Ayres 122
His committee consists of Professors: X. Chen (Chair), Y-T Chen, Rosinski, and Hilafu (Bus An & Stats).
ORAL SPECIALTY EXAMINATION
SPEAKER: Stephen Galloway, University of Tennessee
TIME: 3:00 PM
ROOM: Ayres 113
His committee consists of Professors: Wise (chair), Schulze, and Berry (EECS).
COMPUTATIONAL and APPLIED MATHEMATICS (CAM) SEMINAR
TITLE: An AMDiS Tutorial
SPEAKER: Simon Praetorius, Technische Universität Dresden
TIME: 3:35 PM-5:00 PM (note change)
ROOM: Ayres G013 (note change)
AMDiS (Adaptive MultiDimensional Simulations) is a C++ library to solve a broad class of partial differential equations (PDE) using adaptive finite elements.
This will the third, and last, hands on tutorial on its use.
ORAL SPECIALTY EXAMINATION
TITLE: A Bayesian Topological Framework for Cell Tracking Using Ensemble Kalman Filter.
SPEAKER: Le Yin, University of Tennessee
TIME: 1:00 PM-3:00 PM
ROOM: Ayres 110
Microscopy image video allows elaborated analysis of intracellular movements of organelles in a plant cell. The large data set obtained from the video can be only analyzed by automated algorithms. Here we propose a novel algorithm that can track the organelle movements and reconstruct the trajectories on stacks of image data. This algorithm is based on topological data analysis and stochastic filtering.
The committee consists of: Dr. Vasileios Maroulas,
Dr. Christopher Strickland,
Dr. Andreas Nebenführ,
Dr. Steven M. Abel
