Research on Ilizarov external fixation devices with the aim of being able to accurately predict the behaviour of the device under real-world loading conditions. Musculoskeletal and numerical modelling are used to create a high-fidelity model of the device and lower limb to which it is attached.
“Evaluating digital image correlation speckle pattern quality using finite element based displacement fields” – by Noko Phukubye
This work presents an attempt to understand the relationship between digital image correlation (DIC) speckle patterns and the accuracy of DIC measurement results. Following this, optimised patterns are to be established and generated in the absence of physical limitations. The use of finite element methods is imployed for the deformation of images to generate ground truths for the error analysis.
The problem statement to be addressed by this research project is that the operational capabilities of a nutating grinding mill are poorly understood due to a lack of knowledge of its structural dynamics: the input, output and internal forces of the machine. This lack of knowledge has led to reliability issues for commercial parties such as the De Beers diamond company.
“Testing Device for Articulating Drop Foot Orthosis ” – by Karl Zapke
Drop foot is a disability which causes weakness in the upward tilt of the foot. This results in issues arising when walking, causing toes to be dragged and scuffed when bringing the foot forward for the next step. This disability is caused by damage to the nervous system. Drop foot can be temporary but also results in a permanent disability. Orthotic devices help strengthen and support muscles during rehabilitation. They also aid in moving muscles and limbs that have partially or completely lost mobility. Existing ankle foot orthosis (AFOs) consists of large and heavy articulating devices, allowing the foot to have limited movement, or non-articulating devices, fixing the foot in a set position, allowing for no movement at all. Both types of devices negatively influence the person’s health and results in discomfort. AFO devices which can be used daily mostly consists of non-articulating devices and few to no articulating AFO devices exist for daily use as well as few to no articulating AFO devices allow for multiple degree-of-freedom movement.
This research aims to design an articulating AFO for daily use by people diagnosed with drop foot and produce a prototype that could be used for clinical trials. A testing device will be designed and manufactured to assess the AFO.
“Characterising Commercial Citrus Pre-Cooling and Development of Simulator Equipment for Investigating Chilling Injury ” – by Eugene Sadie
The aim of this research is to characterise cooling dynamics in commercial precooling and develop a laboratory setup that replicates the observed protocols, with the goal of correlating chilling injury occurrence with different cooling methods.
“The design and topology optimization of a heliostat backing structure” – by Michael Du Plessis
I am investigating the design and topology optimization of a heliostat backing structure to minimise mirror distortion under environmental loads. My work uses specialised optimisation software to ensure a stiffer, more efficient design, balancing structural performance, weight, and manufacturability. I aim to enhance heliostat reliability by collaborating with my university supervisors and leveraging solar energy industry guidelines.
“Gait and load analysis in patients fitted with an Ilizarov frame” – by Thembinkosi Mkhabela
My project focuses on gait and load analysis in patients fitted with an Ilizarov frame. The aim is to measure the forces acting on the tibia during movement by utilizing motion capture and OpenSim. The outcomes could help improve patient rehabilitation and optimize frame design
