Project and Practicum Ideas

· Undergraduate (CA3/CA4) and/or taught M.Sc. projects/practicums: I am interested, particularly, in supervising projects with some mathematical or applied mathematical content. Often such projects have a visualisation aspect, and may involve modelling and/or simulation.

- At present, I teach Operations Research so that I would consider project ideas in that area (mathematical programming, simulating, queue systems, game theory, etc)

- Previously, I have suggested a software testing application of Cylindrical Algebraic Decomposition (which would be a bit “researchy”) and perhaps more could be done with this; also, maybe something on applications of Gröbner bases in Computer Science. Use could be made of the freely available software QEPCAD.

- A rather different idea (suggested by radiative transfer research) would be creation of a water body simulation (with special emphasis on visualisation); however, the corresponding mathematics would be a little specialised (though manageable).

- A particular, perhaps frivolous idea is development of software for visualising “three spheres”, and higher dimensions generally (see ProjectSuggestions/Spec_3_Sphere_visualisation.pdf for some background).

- Software considerations in airborne systems and equipment certification (RTCA DO-178C, December 2011) is a revision of the successful, widely used RTCA DO-178B. These new guidelines/considerations have supplements on the use of each of formal methods, model based development and OO development. Projects or practicums based on this could be quite interesting.

Background

Since October 2000 I have been a Lecturer in the School of Computing at DCU. Before that most of my career was in the aerospace industry, with occasional spells lecturing on Mathematical Physics/Applied Mathematics at University College Cork (UCC). I worked on several European Space Agency missions (development of the on-board attitude and control software for the ISO, SOHO and XMM satellites, in-flight payload calibration of the HIPPARCOS satellite). My industrial experience includes considerable work on applying software engineering standards, particularly those of ESA and civil aviation standard RTCA/DO-178B, and software quality management. Recent work, with Enterprise Ireland support, includes industrial collaboration for development of non-contact optical measurement of water properties, particularly in manufacturing settings.
