18 September 2017: Academic Speed Dating Event

Posted on

The idea behind this event, taking place in Newcastle, is to bring together members from other Newcastle and Durham departments to make 10 minute presentations about aspects of their research where a potential collaboration with Mathematicians or Computer Scientists might be beneficial. The audience comprises members of our Schools of Mathematical Sciences and colleagues from Computer Science. The format is ALL presentations followed by the opportunity for further informal discussions and refreshments.

Thursday, 5pm, 8 June, CG93 (Scarborough Lecture Theatre):

Public Lecture by Henry Segerman (Oklahoma State University):

3D Shadows: Casting light on the fourth dimension

Abstract: Our brains have evolved in a three-dimensional environment, and so we are very good at visualising two- and three-dimensional objects. But what about four-dimensional objects? The best we can really do is to look at three-dimensional “shadows”.

6 June 2017: David Cushing presents “Mathematics and Card Tricks”

Posted on

Time and Location:

14:00 in CM107 (Durham)

David will present a one hour lecture on a couple of card tricks and the mathematical ideas behind them. First he will investigate the De Brujin sequences (which are used in coding theory) and then he will look at what happens mathematically when a deck is shuffled and how we can use this structure to our advantage in a trick.

Maciej Koutny (Newcastle, CS): Synthesis of Petry Nets with Whole-place Operations and Localities

Time and Location:

14:00 in E245 (Durham)

Abstract:

Synthesising systems from behavioural specifications is an attractive way of constructing implementations which are correct-by-design and thus requiring no costly validation efforts. In this talk, systems are modelled by Petri nets and the behavioural specifications are provided in the form of step transition systems, where arcs are labelled by multisets of executed actions.
