Study of the use of Electret Ion chambers as radom dosimeters in South Africa
(University of the Western Cape, 2002)
Radon is a naturally occuring radioactive gas which has been shown to be a major contribution to background dose. The underground mines in South Africa present a major occupational hazard. A need for cheap personal monitoring ...
(p.n.) Reactions on 59co in the intermediate energy range
(University of the Western Cape, 1992)
Detailed theoretical investigations [Chi80,Mos82,Kle85] of (p,n) and (p,p') data
indicate that the reaction mechanisms operative at intermediate energies and for
energy losses up to several tens of MeV are predominantly ...
Inclusive (p, α) and (p,³He) cross sections induced by 100 MeV protons on ⁴⁰Ca
(University of the Western Cape, 2006)
Alpha clusteri ng in nuclei is studied with quasi - free knockout reactions. A beam of 100 MeV polarized protons was used in the quasi-free knockout reaction 40 ~a( p,p' a)36 Arat iThemba LABS. While the scattered protons ...
Machine learning approaches to study star formation and black hole accretion in the Meerkat/MIGHTEE survey
(University of the Western Cape, 2023)
Galaxy formation and evolution are driven by two main physical processes: star formation and black hole accretion. Both processes can be traced via the synchrotron emission at radio wavelengths. However, a reliable ...
Carbon, magnesium implantation and proton irradiation on pulsed laser deposited thermochromic thin film of VO2
(University of Western Cape, 2020)
When the spacecrafts orbit in space, it is subjected to significant thermal cycling variation. Thermal regulation of the spacecraft temperature is required to ensure a good
operation of the small crafts such as CubeSats ...
Using internet -enabled remote instrumentation for research and training in physics: Evaluation of different diffusion barriers for silver metallization
(University of the Western Cape, 2007)
The growth of the Internet has led to many interesting developments for both educational and commercial purposes. In this project an attempt was made to use the Internet for a research purpose to facilitate the determination ...
Accelerating reionization simulations using machine learning
(University of the Western Cape, 2023)
Epoch of Reionization (EoR) refers to the time in the history of the universe when the appearance of the first luminous sources reionized the intergalactic medium (IGM). The EoR carries a wealth of information regarding ...
Structural features of air-processible methyl ammonium lead triiodide (MAPbI3) perovskite thin films grown on Al-doped ZnO Nanowire Arrays
(University of the Western Cape, 2023)
The performance of air stable, mixed halide (MAPbI3-xClx) perovskite based solar cells is highly dependent on the quality and stability of the perovskite thin film, which in turn, is dependent on the substrate on which it ...
Sample selection effects in laduma stacking experiments
(University of the Western Cape, 2023)
This study explores the impact of selection effects introduced by input optical cata-logues on high-redshift stacking experiments. Using the Hi stacking technique, the Hi content of LADUMA synthetic data cubes is analyzed ...
