Joint rolling-horizon scheduling of materials processing and lot-sizing with sequence-dependent setups (2007)
Journal Article

A lot sizing and scheduling problem from a foundry is considered in which key materials are produced and then transformed into many products on a single machine. A mixed integer programming (MIP) model is developed, taking into account sequence-depen...

Examining the uncertainty of the recovered surface normal in three light photometric stereo (2007)
Journal Article

Although the three light photometric stereo technique has been used in many applications, there is little published work concerned with characterizing the uncertainty of these systems due to the involvement of a number of complicating factors. This p... Read More about Examining the uncertainty of the recovered surface normal in three light photometric stereo.

Streamlined variance calculations for semiparametric mixed models (2007)
Journal Article

Semiparametric mixed model analysis benefits from variability estimates such as standard errors of effect estimates and variability bars to accompany curve estimates. We show how the underlying variance calculations can be done extremely efficiently... Read More about Streamlined variance calculations for semiparametric mixed models.

The effect of Mach number on unstable disturbances in shock/boundary-layer interactions (2007)
Journal Article

The effect of Mach number on the growth of unstable disturbances in a boundary layer undergoing a strong interaction with an impinging oblique shock wave is studied by direct numerical simulation and linear stability theory (LST). To reduce the numbe... Read More about The effect of Mach number on unstable disturbances in shock/boundary-layer interactions.

Constraint-based approach to investigate the process flexibility of food processing equipment (2006)
Journal Article

Over the last decade the UK food processing industry has become increasing competitive. This leads the sector to maintain high numbers of product variations.
