Assessing predictive performance and transferability of species distribution models for freshwater fish in the United States
… 4 respectively. Chapter 2 showed that the discrimination power of SDMs for 76 non-game fish species depended on data quality, species' rarity, statistical modeling technique, and incorporation of spatial autocorrelation. The area under the Receiver-Operating-Characteristic curve (AUC) in …

Analysis of populations within the UAE using tandem repeat DNA markers
… D16S539, vWA, THO1, TPOX and CSF1PO (GenePrintTM PowerPlexTM 1.2 System) were used to profile 229 UAE native Arab (100 from Sharjah and 129 from Abu Dhabi), 194 Indian, 197 Pakistani and 121 Egyptian individuals. The data were analysed to estimate a number of forensic and paternity parameters, …

Automatic Behavioral Analysis from Faces and Applications to Risk Marker Quantification for Autism
… It is known that 3D features have higher discrimination power than 2D features; however, usually 3D features are not readily available at testing time. For pose-invariant facial expression recognition, we utilize multi-modal features at training and exploit the cross-modal relationship at …

Memory as discrimination: Strategic processing of retrieval cues
… variety of outcomes are possible. The memory-as-discrimination view, investigated as part of this thesis, suggests that factors such as cue overload, distinctiveness, and potentially others contribute to a process of memory retrieval where diagnosticity is central (Nairne, 2002). Under such a …
