An investigation of the aerodynamic admittances and aerodynamic weighting functions of trains (2009)
Journal Article

Increasing train speeds combined with the predicted reduction in the weight of new trains ensure that the effect of crosswinds on train stability is of continued interest to the rail industry. Changes in the approaching wind velocity can in turn lead... Read More about An investigation of the aerodynamic admittances and aerodynamic weighting functions of trains.

Upper bounds for α-domination parameters (2009)
Journal Article

We provide a new upper bound for the α-domination number in terms of a parameter α, 0 < α ≤ 1, and graph vertex degrees. This result generalises the well-known Caro-Roditty bound for the domination number of a graph. The same probabilistic constructi... Read More about Upper bounds for α-domination parameters.

A review of wave energy converter technology (2009)
Journal Article

Ocean waves are a huge, largely untapped energy resource, and the potential for extracting energy from waves is considerable. Research in this area is driven by the need to meet renewable energy targets, but is relatively immature compared to other r... Read More about A review of wave energy converter technology.

Lot sizing and sequencing optimisation at an animal-feed plant (2009)
Journal Article

This paper studies a challenging case of joint lot sizing and scheduling in a manufacturing plant for animal feed compounds. A key characteristic of this industry is that certain products can perform a production line "cleaning" function if a suffici...

Windage power losses from spiral bevel gears with varying oil flows and shroud configurations (2009)
Journal Article

In many aero-engines, the power to drive accessories is transmitted through high speed bevel gears in a chamber in the center of the engine. The windage power loss (WPL) associated with these gears makes a significant contribution to the overall heat...

Stress integration method for a nonlinear kinematic/isotropic hardening model and its characterization based on polycrystal plasticity (2009)
Journal Article

Sheet metal forming processes generally involve non-proportional strain paths including springback, leading to the Bauschinger effect, transient hardening, and permanent softening behavior, that can be possibly modeled by kinematic hardening laws. In... Read More about Stress integration method for a nonlinear kinematic/isotropic hardening model and its characterization based on polycrystal plasticity.
