Modelling water droplet movement on a leaf surface. Abstract Modelling droplet movement on leaf surfaces is an important component in understanding how water, pesticide or nutrient is absorbed through the leaf surface. A simple mathematical model is proposed in this paper for generating a realistic, or natural looking trajectory of a water droplet(More)
A curvilinear thin film model is used to simulate the motion of droplets on a virtual leaf surface, with a view to better understand the retention of agricultural sprays on plants. The governing model, adapted from Roy et al. (2002 J. Fluid Mech. 454, 235-261 (doi:10.1017/S0022112001007133)) with the addition of a disjoining pressure term, describes the(More)
In the last decade, Australia had applied a large program of privatisation in many sectors of the economy. As a result, the power industry has been deregulated and undergone partial privatisation, creating new specific issues. In present, the bid price has a crucial role in the unit commitment problem. This paper describes a genetic algorithm approach which(More)
Recent academic developments which include a changing student profile, the focus of contemporary research, and social trends have combined to pose significant challenges in first year undergraduate mathematics courses. Issues which arise include the content level, the need to maintain rigour, addressing the needs of specialist and non-specialist students,(More)
