Scale coding a bag of words for real-time video-based action recognition.
(2021)Abstract available in PDF. -
Signal space cooperative communication with partial relay selection.
(2012)Exploiting the available diversity from various sources in wireless networks is an easy way to improve performance at the expense of additional hardware, space, complexity and/or bandwidth. Signal space diversity (SSD) ... -
Signal space diversity with and without Alamouti transmit diversity using generalised selection combining.
(2015)The first contribution is based on M-ary quadrature amplitude modulation (M-QAM) constellations with signal space diversity (SSD) using a single transmit and receive antenna system in the presence of Rayleigh fading. Two ... -
Soft-output detection for transit antenna index modulation-based schemes.
(2016)Abstract available in PDF file. -
Spatial modulation : improving throughput over non-cascaded fading channels and performance analysis over cascaded fading channels.
(2012)Small mobile devices which have an ability to access the world wide web (WWW) wirelessly are in demand of late. This demand is attributed to the fact that video and audio streaming are cost effectively accessible via the ... -
A structure from motion solution to head pose recovery for model-based video coding.
(2005)Current hybrid coders such as H.261/263/264 or MPEG-l/-2 cannot always offer high quality-to-compression ratios for video transfer over the (low-bandwidth) wireless channels typical of handheld devices (such as smartphones ... -
Study of lower sampling intervals on rainfall queue characteristics over Radio Links in South Africa.
(2017)Rainfall attenuation in tropical and subtropical regions of the world has continued to attract great interest; as there is a urgent emphasis on proper spectrum management and sharing, particularly at microwave and millimeter ... -
Subspace-based channel estimation for DS/CDMA systems exploiting pulse- shaping information.
(2003)Third generation wireless systems have adopted Direct-Sequence/Code-Division Multiple-Access (DS/CDMA) as the multiple access scheme of communication. This system would typically operate in a multipath fading channel. This ... -
Super-orthogonal space-time turbo codes in Rayleigh fading channels.
(2005)The vision of anytime, anywhere communications coupled by the rapid growth of wireless subscribers and increased volumes of internet users, suggests that the widespread demand for always-on access data, is sure to ... -
Survivability stategies in all optical networks.
(2006)Recent advances in fiber optics technology have enabled extremely high-speed transport -
Thermocouple signal conditioning using artificial neural networks.
(2022)Thermocouples are probably the most widely used temperature sensing devices in industrial applications. This is due to their relatively high accuracy. Thermocouples sense temperature using thermoelectric voltages arising ... -
A token based MAC protocol for wireless ad hoc networks.
(2003)The emergence of portable terminals in work and living environments is accelerating the progression of wireless networks. A wireless ad hoc network is a new network concept where users establish peer-to-peer communication ... -
Towards automatic face recognition using discrete cosine transforms and neural networks.
(1998)Abstract available in PDF. -
Towards the development of an electronic nose.
(2003)Electronic noses are targeted at determining odour character in a fashion that emulates conscious odour perception in mammals. The intention of this study was to develop an organisational framework for electronic noses and ... -
Traffic modeling in mobile internet protocol : version 6.
(2005)Mobile Internet Protocol Version 6 (lPv6) is the new version of the Internet Protocol (IP) born out of the great success of Internet Protocol version 4 (IPv4). The motivation behind the development of Mobile IPv6 standard ... -
Transmit antenna selection algorithms for quadrature spatial modulation.
(2016)The use of multiple-input multiple-output (MIMO) systems has become increasingly popular due to the demand for high data rate transmissions. One such attractive MIMO system is spatial modulation (SM). SM is an ideal ... -
Trellis code-aided high-rate differential space-time block code and enhanced uncoded space-time labeling diversity.
(2017)In this dissertation, a trellis code-aided bandwidth efficiency improvement technique for space-time block coded wireless communication systems is investigated. The application of the trellis code-aided bandwidth efficiency ... -
Trust establishment in mobile ad hoc networks.
(2010)The central focus of this dissertation is mobile ad hoc networks (MANETs) and their security. MANETs are autonomous networks of wireless nodes connected in an ad hoc manner, and have unique characteristics ... -
The use of systems thinking to analyse Nedbank's transformation process to present a holistic approach for effective change in the knowledge world.
(2005)The contemporary approach to change in Nedbank is focused on mechanistic processes with little reference to social systems that exist in organisations. The contemporary approach assumes that an organisation is linear in ... -
Video object segmentation and tracking.
(2005)One of the more complex video processing problems currently vexing researchers is that of object segmentation. This involves identifying semantically meaningful objects in a scene and separating them from the background. ...
