A method for real-time condition monitoring of haul roads based on Bayesian parameter estimation

Author: Heyns, T ; Heyns, PS ; De Villiers, JP Date: Apr 2012 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, both to the ... Read more
Overview of the neural network based technique for monitoring of road condition via reconstructed road profiles

Author: Ngwangwa, HM ; Heyns, PS ; Labuschagne, FJJ ; Kululanga, GK Date: Jul 2008 A healthy road transport systems is essential for any country's social and economic development. It is generally observed that if road deterioration is allowed to increase, the economy will need significantly larger expenditures in subsequent ... Read more
Reconstruction of road defects and road roughness classification using vehicle responses with artificial neural networks simulation

Author: Ngwangwa, HM ; Heyns, PS ; Labuschagne, FJJ ; Kululanga, GK Date: Apr 2010 This paper proposes a procedure for utilizing measured responses on a vehicle to reconstruct road profiles and their attendant defects. The study seeks to capitalize on the popularization of vehicle information systems, where sensors are ... Read more
Statistical gear health analysis which is robust to fluctuating loads and operating speeds

Author: Heyns, T ; Godsill, SJ ; De Villiers, JP ; Heyns, PS Date: Feb 2012 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 gearboxes. It remains a ... Read more
