I'd like to attend the talk, but our polycom room is occupied due to another student seminar. Could someone designate a Google hangout connection for me? Thanks!
Best,

Dear all,
This week, Tomoo Yokoyama will be visiting the Tokyo ERATO MMSD site
from the Kyoto University of Education. He will give our project
colloquium at the usual time, Wednesday (30 May) from 16:30-18:00. The
title and abstract for the talk are given below.
You are all warmly invited to join.
Best regards,
David Sprunger

Tomoo Yokoyama (Kyoto University of Education), Topological methods for analyzing two dimensional flows
We introduce new topological methods, called a word representation and
a tree representation, for analyzing 2D flows. Applying the
topological methods to a plate in a time-dependent uniform flow under
mild conditions, we can estimate when the lift-to-drag ratios of the
plate are maximal and can determine the intermediate topologies of the
uniform flow.
Our talk consists of three parts. In fact, first we quickly review
topology and dynamical systems. Second, we present applications of our
methods. Finally we introduce the theoretical background and discuss
the relative works and the relations between topological structures
and data structures (e.g. implementation of representation algorithms,
contour extraction of streamlines from image data, generating all word
representation by an automaton, generating all tree representation by
"regular tree grammar + cyclic order", improvement of industrial
machines, possibilities of analyzing ocean phenomena and medical
phenomena).
