Improving QoS for real-time multimedia traffic in ad-hoc networks with delay aware multi-path routing
A Mobile Ad-hoc Network (MANET) is a wireless network in which nodes, in the absence of fixed access points, communicate via single or multi-hop paths. Each node in a MANET should thus be able to perform necessary routing ...
Regenerator for Varshamov-tenengolts-like synchronisation error correcting codes
Synchronisation errors, that is, the insertion of additional or deletion of valid symbols, are the most difficult class of errors to correct - containing the class of additive errors as a subset. A regenerating algorithm, ...
Efficient packet erasure decoding by transforming the systematic generator matrix of an RS code
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 ...
Data mining: a technique used to extract information from tan delta measurements on medium voltage induction motors
The study attempted to understand the condition of the insulation system and to classify the data according to its condition. Data mining processes were used to gain insight into the data and the condition of the insulation ...
A qualitative assessment of the insulation systems of medium voltage induction motors
The research was an attempt to understand the condition of the insulation system and to classify the data according to its condition. Data mining processes was used to create a model to gain insight into the data and the ...
Status of international interconnections and electricity deregulation in Africa: an overview of the current status in Southern Africa
The Southern African power system is in a state of flux. The grid is expanding and more interconnections are being made. However, vastness of the area and the low power consumption density in most African countries makes ...
Evaluating methods to binarize historic cosmic-ray recordings
Three adaptive image binarization approaches are evaluated to find the method best suited for the binarization of historic cosmic-ray data. The methods are optimized by fine tuning their parameters and they are then ...
On the development of a power quality benchmarking model
The development of a Power Quality (PQ) Benchmarking model is presented. Practical results are discussed to motivate the need of adding value to recorded PQ data by means of benchmarking PQ performance. The importance, ...
Towards PQ regulation in Southern Africa
This paper discuss the regulation of Power Quality (PQ) in Southern Africa from a user perspective
The application of modern technology in power quality management
Little business integration of power quality management (PQM) is forthcoming amongst electrical utilities all over Southern Africa. Restricted access to proper information is the main reason. A integration of tools, ...
