Slip factor prediction for impellers with straight, back-swept blades
(SAIMechE, 2019)ENGLISH ABSTRACT: Slip factor accounts for the deviation of the flow angle from the trailing edge blade angle at the exit of radial impellers. Accurate values are required to predict impeller torque and energy input. The ... -
The economic reality of home PV systems : matching consumption to generation
(SAIEE, 2018)ENGLISH ABSTRACT: The aim of this paper is to provide an economic viewpoint of the benefit of the installation of a home Photo Voltaic system. An hourly daily consumption and generation profile is created for every calendar ... -
Parametric mandible reconstruction plate
(Southern African Institute for Industrial Engineering, 2020)ENGLISH ABSTRACT: This study investigated the feasibility of a parametric mandible reconstruction plate in order to reduce surgical lead time, improve fit, and reduce residual stresses. The parametric plates were generated ... -
The effect of corrosion thinning on the collapse pressure of a submarine pressure hull
(Stellenbosch : Stellenbosch University, 2021-03)ENGLISH ABSTRACT: The effect of corrosion thinning on a submarine pressure hull is investigated using electrochemical and immersion corrosion testing, material characterisation techniques and nonlinear finite ... -
Benefits of GPS-aided altitude estimation in multirotor drones
(Stellenbosch : Stellenbosch University, 2021-03)ENGLISH ABSTRACT: Ongoing research investigates the use of drones for heliostat calibration,however, is limited by the quality of the collected data and thus the positional accuracy of the drone. Evaluation of various drone ... -
An investigation of the seakeeping behaviour of a polar vessel in waves
(Stellenbosch : Stellenbosch University, 2021-03)ENGLISH ABSTRACT: The SA Agulhas II plays a crucial role in logistical and research support in the Southern Ocean and Antarctica. It is estimated that open water transits account for up to 85 % of her total voyages. She ... -
An ARTI Holonic architecture implementation for table grape production management.
(Stellenbosch : Stellenbosch University, 2021-03)ENGLISH ABSTRACT: The management of table grape production is complex, since it must adhere to strict production requirements, facilitate numerous decisions by various experts, and integrate many human ... -
Modelling of the achilles and patella tendon forces during treadmill running.
(Stellenbosch : Stellenbosch University, 2021-03)ENGLISH ABSTRACT: Tendons are dense connective tissue bands which attach muscle to bone, and facilitate the movement of the musculoskeletal system during locomotion. Although tendon loading during running is one of several ... -
Blending of powders for in-Situ Alloying of Ti-6Al-4V laser powder bed fusion
