Job search strategies and social networks : evidence from the Khayelitsha
… It has been suggested that as a response to adverse conditions of the labour market, the use of social networks is an important search strategy in getting access to the labour market. This thesis therefore pays especially attention to social networks. We develop a more formal search model to …

Structure property relationships in track pad rubber as a function of blending conditions
… pads have been known to degrade rapidly under adverse conditions, especially during cross country service where the average life has been estimated to be 500 miles. Several factors have been identified as being the cause for such low service life. One of these is the 'quality of dispersion' …

A study of real-time lighting effects.
… systems need to be able to accurately simulate adverse conditions such as fog and snow. This work explores different real-time lighting effects such as bloom, airlight, shadows in participating media, and soft shadows. Improvements were made by modifying the airlight to model cone light sources, …
