Combining synchronous averaging with a Gaussian mixture model novelty detection scheme for vibration-based condition monitoring of a gearbox

Heyns, Theo; Heyns, P.S. (Philippus Stephanus); De Villiers, Johan Pieter (Elsevier, 2012-10)

This paper investigates how Gaussian mixture models (GMMs) may be used to detect and trend fault induced vibration signal irregularities, such as those which might be indicative of the onset of gear damage. The negative ...
Consistent haul road condition monitoring by means of vehicle response normalisation with Gaussian processes

Heyns, Theo; De Villiers, Johan Pieter; Heyns, P.S. (Philippus Stephanus) (Elsevier, 2012)

Suboptimal haul road management policies such as routine, periodic and urgent maintenance may result in unnecessary cost, both to roads and vehicles. A recent idea is to continually access haul road condition based on ...
A method for real-time condition monitoring of haul roads based on Bayesian parameter estimation

Heyns, Theo; Heyns, P.S. (Philippus Stephanus); De Villiers, Johan Pieter (Elsevier, 2012-04)

Current haul road management techniques, such as routine, periodic and urgent maintenance have shortcomings in many complex haul road environments. Real-time road condition monitoring may significantly reduce maintenance costs, ...
Statistical gear health analysis which is robust to fluctuating loads and operating speeds

Heyns, Theo; Godsill, S.J.; De Villiers, Johan Pieter; Heyns, P.S. (Philippus Stephanus) (Elsevier, 2012-02)

Condition-based maintenance is concerned with the collection and interpretation of data to support maintenance decisions. The non-intrusive nature of vibration data enables the monitoring of enclosed systems such as ...
