Investigating the performance of generator protection relays using a real-time simulator.
(2013)
Real-time simulators have been utilized to perform hardware-in-loop testing of protection relays
and power system controllers for some years. However, hardware-in-loop testing of generator
protection relays has until ...
Performance analysis of cooperative diversity in land mobile satellite systems.
(2013)
Land Mobile Satellite Systems (LMSS) generally differ from other terrestrial wireless systems. The LMSS exhibit unique characteristics with regard to the physical layer, interference scenarios, channel impairements, ...
Adaptive techniques with cross-layer design for multimedia transmission.
(2013)
Wireless communication is a rapidly growing field with many of its aspects undergoing
constant enhancement. The use of cross-layer design (CLD) in current technologies has
improved system performance in terms of ...
Non-binary compound codes based on single parity-check codes.
(2013)
Shannon showed that the codes with random-like codeword weight distribution are capable of approaching the channel capacity. However, the random-like property can be achieved only in codes with long-length codewords. On ...
Cross-layer design for support of delay bound quality of service guarantees over fading channels.
(2013-11-01)
Quality-of-service (QoS) guarantees have become critically important for the transmission of real-time multimedia traffic in next generation mobile wireless networks. The aim of this dissertation is to investigate the ...
Markerless pose tracking of a human subject.
(2013-05-13)
High capacity wireless and xed-line broadband services have a relatively small footprint
over South Africa's vast expanse. This results in many rural areas, as well as
military communication when deployed, relying on ...
Characterization and modelling of effects of clear air on multipath fading in terrestrial links.
(2013-11-06)
The increased application of digital terrestrial microwave radio links in communication networks has renewed attention in techniques of estimating the probability of multipath fading distributions. Nevertheless, the ...
Modeling and torque control implementtion for an 8/6 switched reluctance motor.
(2013-05-30)
This thesis begins with a brief introduction of the basic principles of operation of SRMs, and
explains how flux characteristics are derived from voltage and current measurements, and
presents results obtained from an ...
Cooperative diversity techniques for future wireless communications systems.
(2013)
Multiple-input multiple-output (MIMO) systems have been extensively studied in the past
decade. The attractiveness of MIMO systems is due to the fact that they drastically reduce
the deleterious e ects of multipath fading ...
The design and construction of an experimental MgO cold cathode X-ray tube for use in XRF spectrometry.
(2013-05-23)
An introduction to the fundamental concepts of X-ray physics and X-ray tube design is given.
This discussion also includes a brief description of various X-ray tube types available
commercially for a number of different ...
