    Abstract: Flooding is among the most extreme weather events, endangering lives and causing significant property damage each year. Flood events in the Centurion area occur every year during the rainy season. This causes considerable damage to road infrastructure in both residential and commercial areas. The objective of this study is to incorporate hydraulic/... Show More

    Abstract: Path analysis is used to estimate a system of equations of the observed variables. These models assume perfect measurement of the observed variables. The relationships between observed variables are modeled. These models are used when one or more variables is mediating the relationship between two others. Structural equation modeling is a methodolo... Show More

    Abstract: The fusiform face area, or FFA, is a small region found on the inferior (bottom) surface of the temporal lobe. It is located in a gyrus called the fusiform gyrus.Studies in humans have shown that the FFA is sensitive to both face parts and face configurations. Recoding activity in the FFA showed that most of the neurons in the FFA are active in res... Show More
