An approach to authenticate magnetic stripe bank card transactions at point-of-sale terminals
Nair, Kishor Krishnan (North-West University (South Africa) , Potchefstroom Campus, 2015)Magnetic stripe card technology has been deployed for more than five decades worldwide and is extensively used in banking. Data embedded in them are often relied upon as a benchmark for user authentication. As such reliance ... -
Automatic Modulation Classification through clustering in the I/Q plane
Mouton, J.P. (North-West University (South Africa), 2020)Automatic Modulation Classification (AMC) refers to a process where the modulation scheme of a signal of interest is determined. It is not a requirement of an AMC system to recover the original data contained in the signal. ... -
Building a scalable virtual community on commodity hardware and open source software
Alberts, Andreas Jacobus (North-West University, 2008)The information era has brought upon us waves of change that brings affordable technology Within the reach of the average person. Computers connected to the Internet, part of our daily living, have led to the formation of ... -
Channel estimation and equalisation using generative adversarial networks
Oosthuizen, Andrew John (North-West University (South Africa)., 2023)Channel State Information (CSI) estimators are used in everyday communication systems to estimate channel impairments that affect transmitted data, and to equalise the impaired data to a more accurate state. However, ... -
A cluster-based Bayesian approach to reliable route discovery in large-scale mobile ad hoc networks
Troskie, A. (2021)The application of MANETs have become a central point of focus in the development of wireless networks. However, MANETs still face the challenge of reliable route discovery in large-scale networks under adverse node failure ... -
Comparing network coding implementations on different OSI layers
Van Wyk, Jacobus Leendert (North-West University, 2010)Network coding is a technique used to increase the capacity of a network by combining messages sent over the network. The combined messages could be separated by using sufficient original messages which were used to combine ... -
A comparison of wireless node topologies for network coding using practical path-loss models
Böning, F.J.; Helberg, A.S.J.; Grobler, M.J. (IEEE, 2010)In this paper, we discuss the physical arrangement of wireless nodes to form topologies suitable for the implementation of Network Coding. Boundaries for the most favorable placement of the nodes to form Bow-Tie and Butterfly ... -
Delay modelling and synchronisation of telecontrol networks
Cilliers, Anthonie Christoffel (North-West University, 2004)Eskom, South A6ica's largest supplier of electricity, uses a vast telecommunication network to control and monitor all operations in remote locations such as substations. As Eskom expanded the electricity network across ... -
Design of effective decoding techniques in network coding networks
Von Solms, Suné (North-West University, 2013)Random linear network coding is widely proposed as the solution for practical network coding applications due to the robustness to random packet loss, packet delays as well as network topology and capacity changes. In order ... -
Development of a machine learning plant growth estimator for hydroponics
Ngorima, Simbarashe Aldrin (North-West University (South Africa)., 2022)Growth stage estimation in indoor farming is crucial for precision agriculture. It reduces the wastage of resources such as nutrients and water in plant cultivation. Overly, yield and quality of the agricultural produce ... -
The development of a multimedia reader for distance learning
Reichel, Erich (North-West University, 2005)The goal of this project was to produce a device which can provide distance learning students with a method of learning by means of enriched study material. This device must be able to display study material in the form ... -
Development of a system for tracking objects in a confined space
De Wet, Sarel Joubert (North-West University, 2009)The Pebble Bed Modular Reactor (PBMR) is one of the alternative generation options that Eskom is currently investigating to replace their old coal-fired plants. The PBMR plants are smaller than conventional plants and ... -
Dynamic modelling of a control valve
Helling, Arnold (North-West University, 2004)Process industries today enjoy significant benefits from advances made in the field of simulation as well as technologies that model normal plant operation. Plants however continue to suffer during abnormal operation such ... -
Efficient packet erasure decoding by transforming the systematic generator matrix of an RS code
Versfeld, D.J.J.; Helberg, A.S.J.; Ferreira, H.C. (IEEE, 2008)We consider the erasures-only decoding of Reed-Solomon codes. One class of erasure decoders of algebraic codes can be viewed as a transformation of the systematic generator matrix, as first noticed by Berlekamp. We extend ... -
