Computational Fluid Dynamic Study of Heaving-to
This study looks at the fluid interactions from the wake of a sail boat performing the heaving-to storm tactic in heavy weather seas with the waves. This interaction causes the wave height in the wake to be reduced. The fluid flow in the top layer of the wave is seen to move with the wake as the …

Measuring inequality of opportunity in South Africa
… applied to the first wave of the National Income Dynamic Study (NIDS). The dissimilarity index estimates the opportunities that need to be reallocated, for all economically active South Africans to have equal access to employment in spite of their circumstances. Whereas the inequality of economic …

Lung Perfusion CT: Differentiation between Lung Cancer and Progressive Massive Fibrosis
… fibrosis. Using 16 channel multi-detector CT, a dynamic study was performed by a multiple spiral acquisition technique at 0 (precontrast), 15, 30, 45, 60, 90, 120, 180, and 300 seconds after contrast material injection. Perfusion images were reformatted using these source images. The grades were …
