The performance of bolt-reinforced and shotcreted in-stope pillar in a rockburst prone areas

Historically, the design of the in-stope pillar in underground excavations has been based on empirical formulae and numerical modelling. Although these design methods have been extensively applied in several gold mines in South Africa, rockburst, in-stope pillar burst/failure are continuously reported as the major problem faced by mines. Therefore, this study attempts to compare the performance...

Implementation of an adaptive burst DQPSK receiver over shallow water acoustic channel

In an environment such as underwater channel where placing test equipments are difficult to handle, it is much practical to have hardware simulators to examine suitably designed transceivers (transmitter/receiver). The simulators of this kind will then allow researchers to observe their intentions and carry out repetitive tests to find suitable digital coding/decoding algorithms. In this p...

A Study on Burst Error Statistics and Error Modelling for MB - OFDM UWB Systems

Error models characterize the statistics of bursty error sequences encountered in digital wireless channels and are therefore, useful for the cross-layer design of wireless networks. In this paper, target error sequences are generated by computer simulations of multiband orthogonal frequency division multiplexing (MB-OFDM) ultra wideband (UWB) systems. A corresponding generative model is then d...

Review of Vortex Methods for Simulation of Vortex Breakdown

The aim of this work is to identify current developments in the field of vortex breakdown modelling in order to initiate the development of a numerical model for the simulation of F/A-18 empennage buffet. Some attempts at using vortex models for prediction of vortex breakdown were found in the open literature. Their advantages and shortcomings are discussed, allowing the evaluation of their fea...
