Author:Baumbach, JDate:Sep 2010The psychophysics of human vision describes how humans perceive and process information in a scene. The physiological aspects (e.g. spatial resolution and spectral resolution) as well as the psychological aspects of vision have been investigated. ...Read more
Author:Baumbach, JDate:Nov 2010Camouflage is one of the methods a soldier in the field employs to increase survivability, and decrease probability of detection. A camouflage pattern can only be effective if it matches the spectral properties (amongst others, colour) as ...Read more
Author:Modibedi, Remegia MDate:Dec 2011Alternative energy resources are needed to alleviate the energy crisis. Fuel cells are one of the examples to help solve the problem. The main goal of this research is to reduce the amount of Pt required in fuel cells. Thus the outcome of ...Read more
Author:Booth, R; Meyer, T; Varzinczak, IDate:Sep 2012We introduce Propositional Typicality Logic (PTL), a logic for reasoning about typicality. We do so by enriching classical propositional logic with a typicality operator of which the intuition is to capture the most typical (or normal) ...Read more
