Toward Authentication Mechanisms for Wi-Fi Mesh Networks
(University of the Western Cape, 2011)Wi-Fi authentication mechanisms include central authentication, dynamic and distributed authentication and some encryption methods. Most of the existing authentication methods were designed for single-hop networks, as ... -
Toward best management practices for the growth of the abalone Haliotis midae Linnaeus on a commercial South African abalone farm
(University of the Western Cape, 2008) -
Towards a chereme based dynamic South African sign language gesture recognition system
(University of the Western Cape, 2007)Hand gestures are a natural and intuitive way of human to human communication. Motivated by the achievements made towards automatic speech recognition, and by the ease with which people sign, many researchers started ... -
Towards a classification system of significant water resources with a case study of the Thukela river
(University of the Western Cape, 2005)The increasing demand for water to provide for South Africa's growing population has resulted in increasing pressure being placed on the country's limited water resources. Water developments however cannot be undertaken ... -
Towards a groundwater source and aquifer protection zoning policy in South Africa: Assessment of the legal, socio-economic and institutional arrangements
(University of Western Cape, 2009)The need for a fundamental change in our approach to water management in South Africa is largely underpinned by the country's Constitution (Act 108 of 1996). Section 24 in Chapter 2 of the Constitution is perhaps the ... -
Towards a unified modelling framework for adaptive networks.
(University of the Western Cape, 2014)Adaptive networks are complex networks with nontrivial topological features and connection patterns between their elements which are neither purely regular nor purely random. Their applications are in sociology, biology, ... -
Towards an unravelling of the taxonomy of Chrysaora (Scyphozoa; Semaeostomeae; Pelagiidae) from around South Africa
(University of the Western Cape, 2017)Historically, two species of Chrysaora are known from the Benguela Current Ecosystem: C.fulgida (Reynaud 1830) and C. africana (Vanhöffen 1902). However a third morphotype is now seen, which bears a resemblance to both. ... -
Towards ensuring scalability, interoperability and efficient access control in a triple-domain grid-based environment
(2012)The high rate of grid computing adoption, both in academe and industry, has posed challenges regarding efficient access control, interoperability and scalability. Although several methods have been proposed to address ... -
Towards rapid electrochemical test system of polyanilino-laccase-on-gold enzyme nanobiosensor for water estrogens
(2013)Current water treatment technologies do not remove many endocrine disruptor compounds (EDCs) such as 17α-ethynylestradiol (EE2) in its entirety, and the amount of these pollutants that continues to enter the aquatic ... -
Towards stimuli-responsive functional nanocomposites: smart tunable plasmonic nanostructures Au-VO2
(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 metal ... -
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 ... -
Towards understanding the groundwater dependent ecosystems within the Table Mountain Group Aquifer: a conceptual approach
(University of the Western Cape, 2006)Understanding of Groundwater Dependent Ecosystems (GDEs) and their extent within the Table Mountain Group (TMG) aquifer is poor. To understand the dependence to basic ecological and hydrogeological concepts need explanation. ... -

The toxicity of silver nanoparticles
(University of the Western Cape, 2012)Unavailability and contamination of available water resources are major factors contributing to adverse health conditions worldwide. AgNPs present a potential strategy for water purification; however, their ability to ... -
Toxicology and molecular epidemiology of microbes detected in surface water in the Western Cape: The Impact of Informal Settlement
(University of the Western Cape, 2013)Informal settlements are often implicated in surface water pollution with faecal matter. In most instances faecal pollution in the associated surface waters persists despite improvements in sewage removal infrastructure. ... -
Traditional, complementary and alternative medicine in Botswana: patients’ attitudes, knowledge and use
(University of the Western Cape, 2017)BACKGROUND: The purpose of this study was to determine use, knowledge and attitudes towards traditional, complementary and alternative medicine (TCAM) in Botswana among people who visit public health facilities. PRIMARY ... -
Transcription regulation and candidate diagnostic markers of esophageal cancer
(University of the Western Cape, 2009)Esophageal cancer (EC) ranks among the ten most frequent cancers worldwide. Mortality rates associated with EC are very similar to the incidence rates due to the relatively late stage of diagnosis and the poor efficacy of ... -
Transcriptional regulatory networks in the mouse hippocampus
(University of the Western Cape, 2007)Neurological diseases are socially disabling and often mortal. To efficiently combat these diseases, a deep understanding of involved cellular processes, gene functions and anatomy is required. However, differential ... -
A transcriptome analysis of apple (Malus x domestica Borkh.) cv ‘golden delicious’ fruit during fruit growth and development
(2013)The growth and development of apple (Malus x domestica Borkh.) fruit occurs over a period of about 150 days after anthesis to full ripeness. During this period morphological and physiological changes occur defining fruit ... -
Transient transgene expression of human coronavirus nl63 orf3 protein
(University of the Western Cape, 2020)Insect-derived baculoviruses have been used extensively as a safe and versatile research model for transgenic protein expression. Preclinical studies have revealed the promising potential of Baculoviruses as a delivery ...
