(1998-05)This project was mainly proposed to make available, to the coal mining industry a set of default friction values that could be used with more confidence in network simulation programs, during the project use was made of ...
-
(2006-10)The temperature coefficient of standard resistors of various types is well-known to within an acceptable uncertainty, for the purposes that these resistors are used for in most calibration laboratories. There are instances ...
-
(2008-04)The supply of sustainable energy is crucial for poverty reduction and economic development in Africa. Such supply to the private sector and to households is necessary to improve productivity and efficiency and ensure that ...
-
(2013-09)Web Real-Time Communication (WebRTC) introduces real-time multimedia communication as native capabilities of Web browsers. With the adoption of WebRTC the Web browsers will be able to use WebRTC to communicate with one ...
-
(SABO CONFERENCE 2014, 2014-09)A method to determine the timeline of captured images of the Cordin 550-32 Ultra-High Speed Camera has been developed. The method is aimed at applications that require photographic diagnostics, with the Cordin camera, in ...
-
(2010-10)Adaptive computer-based training systems aim to enhance the learning experience by personalising the presentation and content delivery according to the preferences of each particular user. The complexity of humans - the ...
-
(2010-10)Mine tremor aftershock sequences from two deep mines in the Far West Rand goldfield, South Africa, were analysed in order to determine the influence of geological and mining parameters on the risk posed by aftershocks. ...
-
(1997-01)The project was initiated to create techniques for processing falls of ground (FOG) data. Those techniques were tested with data from east rand proprietary mines (ERPM). The first part of this report concerns seismic events ...
-
(1995-12)Control of the rock mass deformation near deep level stopes and the avoidance of damaging incidents of violent rock failure require a fundamental understanding of rock failure mechanisms. Research work to gain this ...
-
(1995-12)Modelling of failure processes in rock is an essential adjustment to the analysis of observations of underground rock fracturing. The identification of mechanisms of deformation represents a basic step in understanding of ...
-
(1998-01)This research report discusses the development of preconditioning techniques to control face bursts, for safer mining in seismically hazardous areas. Preconditioning involves regularly setting off carefully tailored blasts ...
-
(1995-05)Literature and industry surveys were invaluable in establishing the presently used methods and experienced in designing bracket pillars. Example of successful and unsuccessful brakect pillars adjacent to dykes and faults ...
-
(2004-01)The initial project objective was to correlate the level of internal broken wire indications, obtained using a magnetic rope test instrument, with rope strength loss and then to propose a given indication level at which ...
-
(1998-12)The design of hard rock pillars, in shallow to intermediate depth hard rock mines, has been redefined as the determination of the pillar system load bearing capacity. This entails the ability to design each of the components ...
-
(1995-12)The overall view of the research being conducted at Impala platinum was to improve pillar design techniques through a rock testing programme, underground instrumentation and back analysis. The laboratory rock testing ...
-
(1998-07)This report describes the process followed in establishing training aids to make employees aware of the dangers of frictional hazards. The actual outputs of the project are training aids that will be used by trainers to ...
-
(2001-07)The original intention of this project was to sponsor a number of non-researchers to attend the workshop. In this particular case, that would have been of little benefit as no definite knowledge in a practically usable ...
-
(2000-10)The purpose of this project was to develop tele-controls to control drilling operations from a distance. The controls were fitted to the prototype quiet rock drill and demonstrated to be working. Noise is a generic hazard ...
-
(The International Speech Communication Association, 2011-08)Afrikaans is one of the eleven official languages of South Africa. It is classified as an under-resourced language. No annotated broadband speech corpora currently exist for Afrikaans. This article reports on the development ...
-
(Association for Computing Machinery, 2015-09)Gamification and digital badging are new concepts to the educational environment, where on completion of specific tasks, an individual can earn a badge or badges showing their achievement. Currently Mozilla Open Badges is ...
