Application of anomaly detection techniques to astrophysical transients
(University of Western Cape, 2021)
We are fast moving into an era where data will be the primary driving factor for discovering new
unknown astronomical objects and also improving our understanding of the current rare astronomical
objects. Wide field ...
Towards stimuli-responsive functional nanocomposites: Smart tunable plasmonic nanostructures au-v02
(University of the Western Cape, 2010)
The fascinating optical properties of metallic nanostructures, dominated by collective
oscillations of free electrons known as plasmons, open new opportunities for the
development of devices fabrication based on noble ...
Structural properties and optical modelling of SiC thin films
(University of the Western Cape, 2020)
Amorphous silicon carbide (a-SiC) is a versatile material due to its interesting mechanical, chemical and optical properties that make it a candidate for application in solar cell technology. As a-SiC stoichiometry can be ...
The effects on student knowledge and engagement when using a culturally responsive framework to teach ASTR 101
(University of the Western Cape, 2020)
The U.S. has a problem: it is not effectively utilizing all the bright young minds available to its science & engineering workforce. In 2012 the President’s Council of Advisors on Science and Technology (PCAST) reported ...
Radiometric investigation of soil and beach sand in Zanzibar
(University of the Western Cape, 2020)
This study presents the results of radiometric investigation of soil and beach sand in Zanzibar. The activity concentration of natural radionuclides (40K, and 232Th and 238U decay products) in beach sand and soil samples ...
Cosmology with HI intensity mapping: effect of higher order corrections
(University of the Western Cape, 2020)
One of the main challenges of cosmology is to unveil the nature of dark energy
and dark matter. They can be constrained with baryonic acoustic oscillations
(BAO) and redshift space distortions, amongst others. Both have ...
Reconstruction of the ionization history from 21cm maps with deep learning
(University of the Western Cape, 2020)
Upcoming and ongoing 21cm surveys, such as the Square Kilometre Array (SKA), Hydrogen
Epoch of Reionization Array (HERA) and Low Frequency Array (LOFAR), will enable imaging
of the neutral hydrogen distribution on ...
Neutral hydrogen in galaxies, its content and the effect of environment on its evolution
(University of the Western Cape, 2018)
Using two hydrodynamic galaxy formation simulations from the Mufasa project that I helped
develop, we aim to better understand the relationship between galaxy evolution and its cold gas
content commonly known as the ...
Feasibility of nuclear plasma interaction studies with the activation technique
(University of the Western Cape, 2018)
Electron-mediated nuclear plasma interactions (NPIs), such as Nuclear Excitation
by Electron Capture (NEEC) or Transition (NEET), can have a signi cant impact
on nuclear cross sections in High Energy Density Plasmas ...
Test of traditional vibrational wisdom by 2 proton stripping onto targets of 108;110Pd,114Cd,115In
(University of the Western Cape, 2018)
The cadmium nuclei have traditionally been regarded as among the best examples
of spherical vibrational nuclei. However, advances in nuclear spectroscopy have
begun to detail the properties of these nuclei at the two and ...
