A Comparison of deep learning architectures for optical galaxy morphology classification
(International Conference on Electrical, Computer and Energy Technologies (ICECET), 2021)The classification of galaxy morphology plays a crucial role in understanding galaxy formation and evolution. Traditionally, this process is done manually. The emergence of deep learning techniques has given room for the ... -
A comparison of Einstein-Boltzmann solvers for testing General Relativity
(American Physical Society, 2018)We compare Einstein-Boltzmann solvers that include modifications to General Relativity and find that, for a wide range of models and parameters, they agree to a high level of precision. We look at three general purpose codes ... -
A comparison of ensemble and deep learning algorithms to model groundwater levels in a data-scarce aquifer of Southern Africa
(MDPI, 2022)Machine learning and deep learning have demonstrated usefulness in modelling various groundwater phenomena. However, these techniques require large amounts of data to develop reliable models. In the Southern African ... -
Comparison of Hi and optical redshifts of galaxies - The impact of redshift uncertainties on spectral line stacking
(Oxford University Press, 2013)Accurate optical redshifts will be critical for spectral co-adding techniques used to extract detections from below the noise level in ongoing and upcoming surveys for Hi, which will extend our current understanding of ... -
A comparison of multi-phase magnetic field tracers in a high-galactic latitude region of the filamentary interstellar medium
(IOP Publishing, 2022)Understanding how the Galactic magnetic field threads the multiphase interstellar medium (ISM) remains a considerable challenge, as different magnetic field tracers probe dissimilar phases and field components. We search for ... -
Comparison of multifactor asset pricing models in the South African stock market [2000–2016]
(MDPI, 2023)The quest for parsimonious models has been a key objective in asset pricing. However, there appears to be no consensus on the most successful asset pricing strategy in the literature, especially for the South African ... -

Comparison of phenolic content and antioxidant activity for fermented and unfermented rooibos samples extracted with water and methanol
(MPDI, 2022)Rooibos is brewed from the medicinal plant Aspalathus linearis. It has a well-established wide spectrum of bio-activity properties, which in part may be attributed to the phenolic antioxidant power. The antioxidant ... -
Comparison of Support Interventions During a Blended Course for Educators from Urban and Rural Settings
(2015)This research focused on the design and delivery of a blended Professional Development (PD) Program for in-service teacher-educators from both urban and rural settings. The overall purpose of the PD Program was to enhance ... -
A comparison of susceptibility patterns of oral Candida isolates from South African and Cameroonian HIV- positive populations
(The International Association for Dental Research (IADR), 2012)METHOD: In this study, Candida isolates were collected from the oral mucosa of 128 South African and 126 Cameroonian HIV-positive patients, by scraping the mouths of consenting patients using sterile cotton swabs. Ethics ... -
The comparison of teen clubs vs. standard care on treatment outcomes for adolescents on antiretroviral therapy in Windhoek, Namibia
