Location-based estimation of the autoregressive coefficient in ARX(1) models
(University of the Western Cape, 2006)In recent years, two estimators have been proposed to correct the bias exhibited by the leastsquares (LS) estimator of the lagged dependent variable (LDV) coefficient in dynamic regression models when the sample is finite. ... -
Long short-term memory recurrent neural networks for signature verification
(UWC, 2003)Handwritten signature verification is defined as the classification process that strives to learn the manner in which an individual makes use of the muscular memory of their hands, fingers, and wrist to reproduce a signature. ... -
Long-range transport clusters, fine particulate matter (PM2.5) and soot concentrations of air masses in Cape Town, South Africa
(University of the Western Cape, 2018)Ambient air pollution is the biggest environmental threat to human health. According to the World Health Organisation (WHO), ambient air pollution kills millions of people worldwide every year. Airborne particulate matter ... -
Long-term vegetation monitoring – a 33 year record from table mountain
(2013)Nearly 40 years ago McLachlan and Moll highlighted the need for a well-defined path system on the Western Table of Table Mountain in the immediate vicinity of the Upper Cable Station (UCS). At that time the numbers of ... -
Low detection of exon skipping in mouse genes orthologous to human genes on chromosome 22
(University of the Western Cape, 2002)Alternative RNA splicing is one of the leading mechanisms contributing towards transcript and protein diversity. Several alternative splicing surveys have confirmed the frequent occurrence of exon skipping in human genes. ... -
Low temperature growth of Amorphous Silicon thin film
(University of the Western Cape, 2007)The growth of amorphous hydrogenated silicon (a-Si:H) thin films deposided by hot wire chemical vapor deposition (HWCVD) has been studied. The films have been characterised for optical and structural properties by means ... -
Low temperature tungsten trioxide nano/micro-systems for applications in gas sensing and electrochromism
(2013)In this work we primarily set out to investigate the technique of Aqueous Chemical Growth as a means of producing WO3 thin films that find applications in gas sensing and electrochromism. For the first time we demonstrated ... -
Luminous red galaxies in simulations
(2010)There have been a number of attempts to measure the expansion rate of the Universe using age-dating of Luminous Red Galaxies (LRGs).Assuming stars in LRGs form at the same time, age-dating of two populations of LRGs at ... -
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 ... -
Macroscopic and Microscopic surface features of Hydrogenated silicon thin films
(University of the Western Cape, 2018)An increasing energy demand and growing environmental concerns regarding the use of fossil fuels in South Africa has led to the challenge to explore cheap, alternative sources of energy. The generation of electricity from ... -
Magmatic-petrogenetic & structural relationships of the peninsula granite of the Cape Granite Suite (CGS) with the Malmesbury group, sea point contact, Saldania belt, South Africa
(University of Western Cape, 2021)The Sea Point contact, Cape Town, South Africa, exposes the contact between the Neoproterozoic Malmesbury Group metasedimentary rocks of the Pan-African Saldania belt and the intrusive S-type Peninsula Granite of the ... -
Magmatic-petrogenetic & structural relationships of the Peninsula Granite of the Cape Granite Suite (CGS) with the Malmesbury Group, Sea Point contact, Saldania Belt, South Africa
(University of the Western Cape, 2020)The Sea Point contact, Cape Town, South Africa, exposes the contact between the Neoproterozoic Malmesbury Group metasedimentary rocks of the Pan-African Saldania belt and the intrusive S-type Peninsula Granite of the ... -
Magnetic substitution in CePt₂Si₂ and CeCu₅In Kondo lattice
(University of the Western Cape, 2013)In the past few decades, the studies of f-electron materials have revealed unusual physical properties such as Fermi-liquid, non-Fermi-liquid behaviour at low temperatures, heavy- Fermion behaviour, valence fluctuation, ... -
Magnetocaloric effect and critical behaviour near the magnetic phase transition temperature in rare-earth compounds
(University of the Western Cape, 2018)Rare-earth intermetallic compounds continue to draw considerable attention, due to their fundamental importance in understanding physical properties and potential applications based on a variety of phenomena. The focus ... -
Male identified same-sex sexual fetish in South Africa: (re)defining sexual relations between people and things
(2010)Historical ethnographic and early psychoanalytic epistemologies on 'fetishism' focus primarily on the fetish 'object', whereby the subject of 'fetish practices' was identified, pathologised and/or socioculturally invalidated ... -
Management and analysis of HIV -1 ultra-deep sequence data
(University of the Western Cape, 2014)The continued success of antiretroviral programmes in the treatment of HIV is dependent on access to a cost-effective HIV drug resistance test (HIV-DRT). HIVDRT involves sequencing a fragment of the HIV genome and ... -
Managing ichthyophonus in multi-species exhibits at the two oceans aquarium
(University of the Western Cape, 2020)Ichthyophonus hoferi has been diagnosed in multiple species at the Two Oceans Aquarium, this study focuses on Rhabdosargus globiceps (White stumpnose). I. hoferi is a mesomycetozoan parasite that multiplies in blood rich ... -
Manipulating biotic and abiotic factors to enhance the remediation of agri-industrial wastewater in pilot-scale constructed wetlands
(University of the Western Cape, 2012)As a consequence of various cellar activities the wine industry produces copious volumes of potentially hazardous wastewater each year. South Africa is one of the top ten wine-producing countries, making the successful ... -
