Analysis of the porous structure of an annular pebble bed reactor
(Atomic Energy Society of Japan, 2009)
This paper discusses the numerical analysis of the porous structure of an annular packed bed. Numerical procedures are described to determine the variation in the porosity, the variation in the coordination number (measure ...
Towards PQ regulation in Southern Africa
This paper discuss the regulation of Power Quality (PQ) in Southern Africa from a user perspective
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, ...
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, ...
Measurement and verification baseline development and service level adjustments for fridge plant systems
In this article the authors provide an overview of a fridge plant system and discuss the data requirements and data selection for baseline development. The baseline development is divided into two scenarios: 1) where ...
A comparative study on fault detection and correction techniques on active magnetic bearing systems
(IEEE-Institute of Electrical and Electronics Engineers, 2007)
In this paper, the authors distinguish between three real-time fault detection, correction and identification schemes for vibration forces on the rotor of a rotational active magnetic bearing (AMB) system. Historical fault ...
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 ...
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 acquisition system for capturing dynamic transients in a control valve
This work presents the development of a data acquisition (DAQ) system to be used in conjunction with fuzzy modelling to derive a dynamic mathematical model of a control valve. Characterising the behaviour of a control valve ...
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, ...
