Predictors of design and adoption of collaborative elearning environments: a multi-method analysis
(University of Western Cape, 2020)Research has shown that collaborative eLearning can provide educational opportunities to groups of learners; both distance learners as well as traditional campus-based learners. It provides innovative educational methods ... -
Processing hidden Markov models using recurrent neural networks for biological applications
(University of the Western Cape, 2013)In this thesis, we present a novel hybrid architecture by combining the most popular sequence recognition models such as Recurrent Neural Networks (RNNs) and Hidden Markov Models (HMMs). Though sequence recognition problems ... -
Quality of service in cloud computing: Data model; resource allocation; and data availability and security
(University of the Western Cape, 2019)Recently, massive migration of enterprise applications to the cloud has been recorded in the Information Technology (IT) world. The number of cloud providers offering their services and the number of cloud customers ... -
Recognition of facial action units from video streams with recurrent neural networks : a new paradigm for facial expression recognition
(University of the Western Cape, 2011)This research investigated the application of recurrent neural networks (RNNs) for recognition of facial expressions based on facial action coding system (FACS). Support vector machines (SVMs) were used to validate the ... -
Resource management in the cloud: An end-to-end Approach
(University of Western Cape, 2020)Cloud Computing enables users achieve ubiquitous on-demand , and convenient access to a variety of shared computing resources, such as serves network, storage ,applications and more. As a business model, Cloud Computing ... -
Short message service normalization for communication with a health information system
(2011)Short Message Service (SMS) is one of the most popularly used services for communication between mobile phone users. In recent times it has also been proposed as a means for information access. However, there are several ... -
The strategic role of software development within the software industry of the Western Cape (South Africa)
(University of the Western Cape, 2016)Africa’s mobile phone penetration has surpassed that of the United States of America and information communication technologies, according to the World Bank, contribute more to its gross domestic product than the global ... -
Synergistic use of promoter prediction algorithms: A choice for small training dataset?
(University of the Western Cape, 2000)This chapter outlines basic gene structure and how gene structure is related to promoter structure in both prokaryotes and eukaryotes and their transcription machinery. An in-depth discussion is given on variations types ... -
Synergistic use of promoter prediction algorithms: a choice of small training dataset?
(University of the Western Cape, 2000)Promoter detection, especially in prokaryotes, has always been an uphill task and may remain so, because of the many varieties of sigma factors employed by various organisms in transcription. The situation is made more ... -
A technique for the evaluation of free and open source e-learning systems
(University of the Western Cape, 2010)Evaluating software is a universal and complex problem. The question is: how should software be selected and adopted, or rather, which of the software packages is the most suitable for a specific environment? Extensive ... -
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 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 ... -
Voice and rural wireless mesh community networks: a framework to quantify scalability and manage end-user smartphone battery consumption
(University of Western Cape, 2021)Community wireless mesh initiatives are a pioneering option to cheap ‘last-mile’ access to network services for rural low-income regions primarily located in Sub-Saharan Africa and Developing Asia. However, researchers ... -
White Space Network Management: Spectrum Quanti cation, Spectrum Allocation and Network Design
(University of the Western Cape, 2017)The unused spectrum in the television broadcasting frequency bands (so-called TV white spaces) can alleviate the spectrum crunch, and have potential to provide broadband connection to rural areas of countries in the ...
