Postgraduate Seminar Speakers 21st May 2015

Postgraduate Seminar Series - Spring 2015
21 May 2015 - 1pm - Zoology Museum (Wallace 129)
"Applying X-ray Computed Tomography to the study of Tephrochronology"
Elizabeth Evans

This week, one of our speakers is Elizabeth Evans, a 1st year PhD student working on a inter-disciplinary project within the Geography and Engineering departments at Swansea University. Elizabeth completed her 4 year Msci degree in Geology at Durham University.

Tephrochronology, the study of volcanic ash as a proxy for sediment age, usually works in the realm of point data (individual grains of ash picked then analysed), 1D line analysis or 2D surface study. X-ray CT is a non-destructive technique that can reveal the three-dimensional geometry of these tephra horizons. These horizons were considered to represent the time they were erupted within the sedimentary record however it seems that things are a bit more complicated. Coupled with the issues of similarity of the materials in the samples this project is set to keep me busy for the next 3 years!
“Existence and uniqueness of stochastic differential delay equation of neutral type”
Yanting Ji

This week, our second speaker is Yanting Ji, a 3rd year Mathematics PhD student at Swansea University. Yanting completed an MSc in Mathematics and Computing for Finance at Swansea University in 2012 and previously achieved a BSc in Mathematics from Australia National University.

Briefly, this talk focusses on constructing the E-U theorem through a numerical scheme under local weak monotonicity and weak coercivity condition.

All are welcome to attend!
