Experiments in thin film deposition : plasma-based fabrication of carbon nanotubes and magnesium diboride thin films.
(2004)
A simple, low-cost plasma reactor was developed for the purpose of carrying out thin film deposition experiments. The reactor is based largely on the Atmospheric Pressure Nonequilibrium Plasma (APNEP) design with a simple ...
Performance of the transmission control protocol (TCP) over wireless with quality of service.
(2001)
The Transmission Control Protocol (TCP) is the most widely used transport protocol in
the Internet. TCP is a reliable transport protocol that is tuned to perform well in wired
networks where packet losses are mainly due ...
A multi-objective particle swarm optimized fuzzy logic congestion detection and dual explicit notification mechanism for IP networks.
(2006)
The Internet has experienced a tremendous growth over the past two decades and with that growth have come severe congestion problems. Research efforts to alleviate the congestion problem can broadly be classified into three ...
Cell search in frequency division : duplex WCDMA networks.
(2006)
Wireless radio access technologies have been progressively evolving to meet the high data rate demands of consumers. The deployment and success of voice-based second generation networks were enabled through the use of the ...
Rain attenuation modelling for Southern Africa.
(2008)
In order to address rain attenuation scattering of millimetric waves and microwave sin Botswana, we have employed a comparison technique to determine the Ro.o1 at fourteen diverse locations in Botswana. In addition we have ...
Repeat--punctured turbo codes and superorthogonal convolutional turbo codes.
(2007)
The use of error-correction coding techniques in communication systems has become
extremely imperative. Due to the heavy constraints faced by systems engineers more
attention has been given to developing codes that ...
Multiuser detection employing recurrent neural networks for DS-CDMA systems.
(2006)
Over the last decade, access to personal wireless communication networks has evolved to a point of necessity. Attached to the phenomenal growth of the telecommunications industry in recent times is an escalating demand for ...
Residue number system coded differential space-time-frequency coding.
(2007)
The rapidly growing need for fast and reliable transmission over a wireless channel motivates the development of communication systems that can support high data rates at low complexity. Achieving reliable communication ...
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 ...
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 ...
