Growth, water use efficiency and stable carbon isotopes in commercial clones of Eucalyptus
… in a great reduction in the country's run-off water. If Eucalyptus continues to be the source of timber in South Africa, the selection of more water use efficient species for planting in existing and new areas has to be implemented. An understanding of the physiological factors ruling growth …

A canal irrigation water allocation model.
A water allocation model was developed to assist with allocation of canal water to competing crop irrigation demands. Multi-period linear programming was utilized to optimally allocate water in both time and space to maximize benefits for an irrigated farm. Irrigation scheduling, crop response and …

Model based prognostic maintenance as applied to small scale PVRO systems for remote communities
… their required levels of productivity at lowest cost. However, using pre-scheduled maintenance on systems that degrade as functions of their operation under uncertain, varying conditions will not guarantee that they meet their productivity at lowest cost. They require maintenance schedules that …
