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 ... -
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 ... -
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 ... -
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. ... -
Carrier grade adaptation for an IP-based multimodal application server: moving the softbridge into SLEE
(University of the Western Cape, 2004)Providing carrier grade characteristics for Internet Protocol (IP) communication applications is a significant problem for IP application providers in order to offer integrated services that span IP and telecommunication ... -
Articulated structure from motion
(University of the Western Cape, 2004)The structure from motion (SfM) problem is that of determining 3-dimensional (3D) information of a scene from sequences of 2-dimensional (2D) images [59]. This information consists of object shape and motion and relative ... -
Affective gesture fast-track feedback instant messaging (AGFIM)
(University of Western Cape, 2005)Text communication is often perceived as lacking some components of communication that are essential in sustaining interaction or conversation. This interaction incoherency tends to make text communication plastic. It is ... -
Social and technical issues of IP-based multi-modal semi-synchronous communication: rural telehealth communication in South Africa
(University of the Western Cape, 2005)Most rural areas of developing countries are faced with problems like shortage of doctors in hospitals, illiteracy and poor power supply. Because of these issues, Information and Communication Technology (ICT) is often ... -
Models and applications of wireless networks in rural environments
(University of the Western Cape, 2005)With the unprecedented growth of the communication industry that the world is experiencing, the demand from rural inhabitants for high quality communications at an economically affordable cost is growing. However, rural ... -
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 ... -
Guaranteed delivery of multimodal semi-synchronous IP-based communication.
(University of the Western Cape, 2005)A semi-synchronous environment consists of a combination of synchronous and asynchronous transport media used to transport messages from source to destination. This thesis explores an empirical solution for guaranteeing ... -
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 ... -
Data mining, fraud detection and mobile telecommunications: call pattern analysis with unsupervised neural networks
(University of the Western Cape, 2005)Huge amounts of data are being collected as a result of the increased use of mobile telecommunications. Insight into information and knowledge derived from these databases can give operators a competitive edge in terms of ... -
Chereme-based recognition of isolated, dynamic gestures from South African sign language with Hidden Markov Models
(University of the Western Cape, 2006)Much work has been done in building systems that can recognize gestures, e.g. as a component of sign language recognition systems. These systems typically use whole gestures as the smallest unit for recognition. Although ... -
Metric of trust for mobile ad hoc networks using source routing algorithms
(University of the Western Cape, 2006)This thesis proposed and presented technical details of new probabilistic metrics of trust in the links wireless ad hoc networks for unobservable communications. In covert communication networks, only the end nodes are ... -
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 ... -
KernTune: self-tuning Linux kernel performance using support vector machines
(University of the Western Cape, 2006)Self-tuning has been an elusive goal for operating systems and is becoming a pressing issue for modern operating systems. Well-trained system administrators are able to tune an operating system to achieve better system ... -

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 ... -
Automatic real-time facial expression recognition for signed language translation
(University of the Western Cape, 2006)We investigated two computer vision techniques designed to increase both the recognition accuracy and computational efficiency of automatic facial expression recognition. In particular, we compared a local segmentation of ...
