Th e quest for improved self-revenue generation and reduction of the fi nancial burden on government prompted the adoption of public private partnership (PPP) in the management of South African National Parks (SANParks). Accordingly, this paper examined the revenue and conservation implication of PPP in SANParks. Using a statistical t-test of diff erence in means, before and within the PPP, res...

In this report we present essential elements of a conceptual framework for high-level vision (HLV). The scope of HLV is defined as scene interpretation above the level of object recognition. It is shown that models, on which such interpretations can be based, typically describe aggregates composed of meaningful parts, related to each other by temporal and spatial constraints. A frame-based repr...

1. Prove the results about the smoothness of the members of the Matèrn family. Proof. From the class we know that for small values of τ , we have K ν (τ) ≈ Γ(ν)2 ν−1 τ −ν. Also, for the derivatives we have that d dτ (τ ν K ν (τ)) = −τ ν K ν−1 (τ). If the Matèrn family has the correlation function ρ(τ) = 1 Γ(ν)2 ν−1 τ ν K ν (τ), then ρ (τ) = −1 Γ(ν)2 ν−1 τ ν K ν−1 (τ) Note that K ν (τ) = K −ν (τ...

The study's authors believe that children near Sellafield are getting cancer as a result of their fathers' exposure to radiation at work before the children are conceived. They believe children are inheriting a genetic defect caused by radiation exposure of the fathers' sperm. An alternative explanation is that the fathers become contaminated at work and somehow carry radioactivity home (perhap...
