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.

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.
