Predicting Pallet Part Yields From Hardwood Cants
Pallet cant quality directly impacts pallet part processing and material costs. By knowing the quality of the cants being processed, pallet manufacturers can predict costs to attain better value from their raw materials and more accurately price their pallets. The study objectives were 1) to …

Aerodynamic and Structural Design of a Winglet for Enhanced Performance of a Business Jet
… candidate geometries were studied varying the cant angle and the span. The configuration offering the best compromise between induced drag reduction, profile drag increase and weight increase due to the winglet structure and necessary wing structural reinforcement was selected. More refined …

Exclusivity, Bundling and Switching in Communications Markets
… concentration in the downstream market are signi�cant determinants of both the decision to sell in a country and the duration of any exclusivity agreements. The presence of competing technological standards is also shown to result in longer periods of exclusivity indicating slower di�usion of the …

Numerical Investigation of Exotic Phases in Quantum Lattice Models
… and in particular of topological phases. A signi�cant portion of the thesis concerns the investigation of supersymmetric lattice models, which involves signi�cant use of the developed DoQO code. These are a relatively new (2003) family of models consisting of spinless fermions hopping on a lattice …

Weathering Pathways and Limitations in Biogeochemical Models: Application to Earth System Evolution
… carbonatization does not result in a signifi�cant reduction in stabilisation time. Model timeframe is extended over the last 2Ga. Predicted oxygen concentration is shown to depend on the balance between terrestrial and sea floor weathering, which alters the global nutrient delivery rate and …
