Free-fall gravitational acceleration measurement using a pneumatically controlled catch-and-release-system in a semi-rotating vacuum chamber

Mokobodi, Tlou; Greeff, Pieter; Kruger, Oelof; Theron, Nicolaas J. (De Gruyter Open, 2018)

Knowledge of gravitational acceleration in metrology is required for traceable force and pressure calibrations, furthermore the redefinition of the SI base unit of kilogram requires absolute accomplishment of the ...
Real-time underground route identification and route progress using simple on-board sensing and processing

Meeser, Riaan Frederick; Theron, Nicolaas J. (Southern African Institute of Mining and Metallurgy, 2023-01)

The global emphasis on conserving energy resources has led to the adoption of hybrid power systems in vehicles. Optimally applied, hybrid systems can save up to 40% on fuel costs. To optimally manage a hybrid vehicle's ...
Self-sensing active control of emulated tangential tool vibration hardware-in-the-loop

Freyer, Burkhard Heinrich; Theron, Nicolaas J.; Heyns, P.S. (Philippus Stephanus); Pickelmann, Lutz A. (Elsevier, 2021-04)

This study tests the dual functionality of a piezoelectric transducer for active control of emulated tool vibration. The concept of a self-sensing actuator is here applied jointly with adaptive feedback active vibration ...
