Exploration of the impact of genetic counselling and patient support group involvement on retinal degenerative disorders (RDD) patients: a qualitative study
This study explored the experiences of individuals within the clinical genetic service in South Africa, with inherited retinal disease. Methods: This qualitative research was based on a grounded theory approach. Semi-structured interviews were carried out after obtaining approval from the …

Rapid Drawdown Analysis using the Finite Element Method
Rapid drawdown (RDD) occurs when the water level adjacent to a slope or embankment is lowered quickly after a long period of being elevated either at the normal operating level for a dam or in the case of levees, during a prolonged flood. The current state of practice for RDD analysis is a …

Analysis of development policies for women’s empowerment and children’s welfare in MENA countries
… using Spatial Regression Discontinuity Design (RDD), where the outcomes on women’s development are identified and compared at the geographical level. The results depict an overall picture of women’s position within the regions occupied and dominated by Ottoman institutions. The results indicate …

Regional dynamical downscaling and analysis of water balance across different regions and time scales
Employing the regional dynamical downscaling (RDD) technique, we can enhance the spatial and temporal resolution of global reanalysis and general circulation model (GCM) data, providing improved data for studying ecological processes. This method ensures physical validity of the data, albeit at …

Finite element analysis of embankment dam due to rapid drawdown events
… associated with flood loading or rapid drawdown (RDD) conditions. The assessment of slope stability under RDD conditions is difficult to estimate due to the time-dependence of pore pressures within the dam and uncertainties in the shear strength properties of compacted fills. Computational …

GPUMap: A Transparently GPU-Accelerated Map Function
… This thesis also presents GPU-accelerated RDD (GPURDD), which is a type of Spark Resilient Distributed Dataset (RDD) which incorporates GPUMap into its map, filter, and foreach methods in order to allow Spark applicatons to make use of the abstracted GPU acceleration provided by GPUMap.</p>

RNA and DNA Sequence Analysis of the Human Transcriptome
… all 12 types of RNA-DNA sequence differences (RDDs), the majority of which cannot be explained by known mechanisms such as RNA editing or transcriptional infidelity. We developed computational methods to robustly identify RDDs and control for false positives resulting from genotyping, …

Genetics of age-related macular degeneration and Stargardt disease in South African populations
Background: The Retinal Degenerative Diseases (RDD) Research Group in the Division of Human Genetics at UCT has for the past 25 years been intensively investigating a range of RDD phenotypes. Two points of particular note have emerged regarding Macular Degenerations (MD) : (i) that more than 58% of …
