Finite time extinction in nonlinear diffusion equations (2004)
Journal Article
We consider a class of degenerate diffusion equations where the nonlinearity is assumed to be singular (non-Lipschitz) at zero. It is shown that solutions with compactly supported initial data become identically zero in finite time. Such extinction f... Read More about Finite time extinction in nonlinear diffusion equations.
Building better nurse scheduling algorithms (2004)
Journal Article
The aim of this research is twofold: Firstly, to model and solve a complex nurse scheduling problem with an integer programming formulation and evolutionary algorithms. Secondly, to detail a novel statistical method of comparing and hence build bette... Read More about Building better nurse scheduling algorithms.
Trajectories of a DAE near a pseudo-equilibrium (2004)
Journal Article
We consider a class of differential-algebraic equations (DAEs) defined by analytic nonlinearities and study its singular solutions. The main assumption used is that the linearization of the DAE represents a Kronecker index-2 matrix pencil and that th... Read More about Trajectories of a DAE near a pseudo-equilibrium.
Hydride phase formation in carbon supported palladium nanoparticle electrodes investigated using in situ EXAFS and XRD (2003)
Journal Article
In situ EXAFS (extended X-ray absorption fine structure), in situ XRD (X-ray diffraction) and electrochemical studies have been used to investigate the palladium hydride phases of carbon supported palladium nanoparticles as a function of applied pote...

Hybrid heuristics for planning lot setups and sizes (2003)
Journal Article
The planning of a canning line at a drinks manufacturer is discussed and formulated as a mathematical programming model. Several alternative heuristic solution methods are developed, tested and compared on real data, illustrating the trade-offs betwe...

Physical-based friction identification of an electro-mechanical actuator with Dymola/Modelica and MOPS (2003)
Presentation / Conference Contribution
Gas phase electrochemical detection of single latex particles (2003)
Journal Article
In this study we describe zero current potentiometric measurements in a gaseous flame electrolyte, for the detection of single latex particles. Combustion of polystyrene latex particles when added to a premixed hydrogen/oxygen/nitrogen flame, results... Read More about Gas phase electrochemical detection of single latex particles.
Impingement studies for G-DI sprays at elevated temperatures (2003)

Exploring the psychosocial concerns of out-patients with disfiguring conditions (2003)
Journal Article
Objective: This study was undertaken to establish the extent and type of psychosocial need in outpatients attending for treatment for a variety of disfiguring conditions.
Method: A total of 220 outpatients receiving treatment for burns, skin condit... Read More about Exploring the psychosocial concerns of out-patients with disfiguring conditions.
