Scalable Wireless Mesh Networks
(University of the Western Cape, 2016)
Wireless Mesh Networks (WMNs) are wireless multi-hop networks built on
wireless nodes that operate in an Independent Basic Set Identifier (IBSS) mode
of the IEEE 208.11 wireless standard. IBSS is well known as an ad hoc ...
Browser-based and mobile video communication alternatives for Deaf people
(University of the Western Cape, 2011)
This thesis offers some prototypes to provide browser-based and mobile video communication services for Deaf people and evaluates these prototypes. The aim of this research is to identify an acceptable video communication ...
Mobile presentations with interactive chat for m-Learning
(University of the Western Cape, 2010)
Using presentations in an m-Learning environment enables delivery of rich content to a mobile phone learner. This study investigated how to prepare and stream presentations from a desktop computer to a mobile phone in ...
Robust recognition of facial expressions on noise degraded facial images
(University of the Western Cape, 2011)
We investigate the use of noise degraded facial images in the application of facial expression recognition. In particular, we trained Gabor+SVMclassifiers to recognize facial expressions images with various types of noise. ...
Numerical Methods for Mathematical Models on Warrant Pricing
(University of the Western Cape, 2010)
Warrant pricing has become very crucial in the present market scenario. See, for example, M. Hanke and K. Potzelberger, Consistent pricing of warrants and traded options, Review Financial Economics 11(1) (2002) 63-77 where ...
Rendering an avatar from sign writing notation for sign language animation
(University of the Western Cape, 2010)
This thesis presents an approach for automatically generating signing animations from a sign language notation. An avatar endowed with expressive gestures, as subtle as changes in facial expression, is used to render the ...
Hand shape estimation for South African sign language
(University of the Western Cape, 2012)
Hand shape recognition is a pivotal part of any system that attempts to implement Sign Language recognition. This thesis presents a novel system which recognises hand shapes from a single camera view in 2D. By mapping the ...
An investigation into the appropriateness of using agile processes to build an educational management information system
(University of the Western Cape, 2010)
Since there was a need for an Educational Management Information System (EMIS) in the Ministry of Education in Afghanistan, we designed and implemented a prototype for use in the ministry and investigated the appropriateness ...
South African Sign Language Recognition Using Feature Vectors and Hidden Markov Models
(University of the Western Cape, 2010)
This thesis presents a system for performing whole gesture recognition for South African Sign Language. The system uses feature vectors combined with Hidden Markov models. In order to construct a feature vector, dynamic ...
Packet aggregation for voice over internet protocol on wireless mesh networks
(University of the Western Cape, 2012)
This thesis validates that packet aggregation is a viable technique to increase call ca-pacity for Voice over Internet Protocol over wireless mesh networks. Wireless mesh networks are attractive ways to provide voice ...
