The Informal Applied Mathematics seminar will continue with a double bill from James Gregory and Michael Connolly. Talks will take place in Frank Adams 2 (next to the Alan Turing Building's kitchen), with complimentary hot drinks and biscuits from 2.45pm on the atrium bridge. Title and abstracts for the talks can be found below.
James Gregory: Predicting the yield point of tendons and ligaments
Abstract: Yield criteria can be used to determine whether or not a material will yield under some prescribed deformation. One of the most widely used is the von Mises yield criterion. In the first part of this talk, we will discuss the applicability of this criterion to soft tissues by looking at predicted yield strains. We will then consider how we can modify a hyperelastic model of tendons and ligaments to incorporate yielding of collagen fibres, comparing the output to data gathered from experiments on mouse tail tendons.
Michael Connolly: Floating-Point Summation
Abstract: In this short talk we consider the problem of computing the sum of n numbers in floating-point arithmetic. This is one of the most important inner kernels of scientific computing, and while simple to state, it can easily go wrong. We'll examine both the accuracy and speed of different methods of computing floating-point sums and see how the choice of method can have a significant impact on the performance of a numerical algorithm.
FYI: The Informal Applied Seminar is a weekly seminar for all applied mathematics students in the department. We get together on a Friday afternoon for students to speak about what they're working on at the moment. It's not formal - lecturers and staff don't attend - so it can be a good place to get feedback on your talk before an upcoming conference or just good to practise for public speaking in general. We generally meet on the bridge (outside the Alan Turing building first-floor kitchen) 15mins before the start and head to Sandbar for a drink afterwards.
