[logic-ml] Project colloquium by Tomoo Yokoyama on 30 May

[Kohei SUENAGA]

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,

Kohei

> 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).
