Performance estimation of wireless networks using traffic generation and monitoring on a mobile device.
(University of the Western Cape, 2015)In this study, a traffic generator software package namely MTGawn was developed to run packet generation and evaluation on a mobile device. The call generating software system is able to: simulate voice over Internet ... -
Policy based network management of legacy network elements in next generation networks for voice services
(University of the Western Cape, 2002)Telecommunication companies, service providers and large companies are now adapting converged multi-service Next Generation Networks (NGNs). Network management is shifting from managing Network Elements (NE) to managing ... -
Remote surveillance and face tracking with mobile phones (smart eyes)
(University of the Western Cape, 2005)This thesis addresses analysis, evaluation and simulation of low complexity face detection algorithms and tracking that could be used on mobile phones. Network access control using face recognition increases the user-friendliness ... -
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 ... -
A robust audio-based symbol recognition system using machine learning techniques
(University of the Western Cape, 2020-02)This research investigates the creation of an audio-shape recognition system that is able to interpret a user’s drawn audio shapes—fundamental shapes, digits and/or letters— on a given surface such as a table-top using a ... -
Robust facial expression recognition in the presence of rotation and partial occlusion
(University of Western Cape, 2014)This research proposes an approach to recognizing facial expressions in the presence of rotations and partial occlusions of the face. The research is in the context of automatic machine translation of South African Sign ... -
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. ... -
Robust South African sign language gesture recognition using hand motion and shape
(2014)Research has shown that five fundamental parameters are required to recognize any sign language gesture: hand shape, hand motion, hand location, hand orientation and facial expressions. The South African Sign Language ... -
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 ... -
Secure contactless mobile financial services with near field communication
(University of the Western Cape, 2011)This thesis presents the results from work with three prototypes that use Near Field Communication technology to provide secure contactless mobile nancial services on mobile phones. -

Self-tuning Linux Kernel Performance Using Support Vector Machines
(University of the Western Cape, 2006)In this chapter, we provide the motivation and background behind the automatic optimisation of an operating system. We begin with a discussion of some of the difficulties of automatic operating system optimisation and ... -
Semi-synchronous video for deaf telephony with an adapted synchronous codec
(University of the Western Cape, 2009)As Information and Communication Technology (ICT) matures, communication services must be improved to meet the needs of all types of users. For some uses, current Video over Internet Protocol (IP) brings unsatisfactory ... -
SIP-based content development for wireless mobile devices with delay constraints
(University of the Western Cape, 2006)SIP is receiving much attention these days and it seems to be the most promising candidate as a signaling protocol for the current and future IP telephony services. Realizing this, there is the obvious need to provide a ... -
SIP-based location service provision
(University of the Western Cape, 2005)Location-based service (LBS) is a geographical location-related service that provides highly personalized services for users. It is a platform for network operators to provide new and innovative ways of increasing profits ... -
Situation-aware routing for wireless mesh networks with mobile nodes
(University of the Western Cape, 2012)This thesis demonstrates that a situation-aware algorithm improves quality of service on small mesh networks running BATMAN-adv with some mobile nodes. BATMAN-adv is a proactive mesh routing protocol that counts beacons ... -
