Transtibial Prosthetic Socket Fitting: Australian Prosthetist Perspectives On Primary Challenges, Management Strategies, And Opportunities For Workflow And Technological Innovation, Lucy E. Armitage, Kirsty A. Mcdonald, Lauren Kark, Angela Buller, Belinda Ford

Faculty of Engineering and Information Sciences - Papers: Part B

Background: Following transtibial amputation, a custom-built socket is the most common interface between the prosthesis and residual limb. Desire from both prosthetists and prosthesis users for improved socket fitting processes have been well documented. However, there is currently limited information available about prosthetists’ experiences of how prosthetic manufacturing workflow can contribute to socket fit problems.

Objectives: This study aims to determine how socket fit problems are currently detected and managed by prosthetists and to identify challenges, management strategies, and opportunities for workflow and technological innovation during prosthesis manufacture and socket fitting.

Study design: Mixed-method (quantitative and qualitative) survey.

Methods: An …

Development Of A More Accurate Geant4 Quantum Molecular Dynamics Model For Hadron Therapy, Yoshi-Hide Sato, Dousatsu Sakata, David Bolst, Susanna Guatelli, Akihiro Haga

Faculty of Engineering and Information Sciences - Papers: Part B

Objective. Although in heavy-ion therapy, the quantum molecular dynamics (QMD) model is one of the most fundamental physics models providing an accurate daughter-ion production yield in the final state, there are still non-negligible differences with the experimental results. The aim of this study is to improve fragment production in water phantoms by developing a more accurate QMD model in Geant4. Approach. A QMD model was developed by implementing modern Skyrme interaction parameter sets, as well as by incorporating with an ad hoc α-cluster model in the initial nuclear state. Two adjusting parameters were selected that can significantly affect the fragment …

A Photographic Essay On Landslides Across Southeastern New South Wales Triggered By The Rainfall Events Of 2022, Phil Flentje, Connor Larkin, Damian Mulcahy, Larissa Hettiarachchi, Dan Horan, James Cox, Stuart Milling, Peter Tobin, Kevin Bogie

Eastern Australia has experienced a significant magnitude rainfall event of extended duration in the first 7 months of 2022. Across the east coast of New South Wales (NSW) a series of troughs and East Coast Lows occurred during a La Nina weather cycle bringing above average rainfall to the region. As this first half of 2022 La Nina event was drawing to a close the Indian Ocean Dipole entered a negative phase which coincided with another intense East Coast Low in early July 2022 impacting the Illawarra region of NSW. These events caused widespread flooding and significant landslide damage to …

Optimum Auxiliary Fan Location To Control Air Recirculation, Ramakrishna Morla, Shivakumar Karekal, Ajit R. Godbole, Purushotham Tukkaraja, Ping Chang

Faculty of Engineering and Information Sciences - Papers: Part B

This paper presents the optimum auxiliary fan(s) location to control air recirculation in dead-end workings where diesel-powered vehicles operate. Investigations were conducted with various secondary fan locations from the dead-end crosscut with varying the intake air quantities using a 30 m³/s capacity twin 75 kW auxiliary fan and 45 m³/s capacity twin 110 kW auxiliary fan to control air recirculation and DPM. The results showed that if the drive intake airflow rate matches the fan capacity, air recirculation will occur even when the fan is located 10 m away from the crosscut entry. Results also showed …

Prehistoric Landslides: Significance, Recognition, Examples, James V. Hamel, David L. Knott, Phil Flentje, Stephen Fityus

Faculty of Engineering and Information Sciences - Papers: Part B

Prehistoric landslides with a wide range of ages and sizes exist worldwide in both rock and soil. Many are thought to have occurred during Pleistocene time when climates in some areas were harsher and wetter. Subsequent weathering and erosion have subdued topography and other features of prehistoric landslides, often making them difficult to recognize. Recognition is the key to dealing with prehistoric and other old landslides. Old slide masses are usually only marginally stable because past movements reduced available shear strength on their failure surfaces to residual levels. These masses are susceptible to reactivation by construction activities, heavy precipitation, and …

Bulli Pass Landslide Risk Management Part 1 – Hazard Assessment, Andrew Hunter, Phil Flentje, Alan Moon

Faculty of Engineering and Information Sciences - Papers: Part B

The Princes Highway along Bulli Pass is a narrow, heavily trafficked two lane section of the Princes Highway that traverses steep slopes on a grade of 9H:1V on the Illawarra Escarpment, about 11 km north of Wollongong, and 75 km south of Sydney in New South Wales (NSW), Australia. It is an important arterial road for the northern suburbs of Wollongong, connecting Mt Ousley Road (M1 Princes Motorway) at the crest of the escarpment to the suburb of Thirroul on the coastal plain at the base of the escarpment. Bulli Pass has a long history of landslide and rockfall events, …

Hygrothermal Performance Of Vapour-Permeable Wall Membranes In Cooler Australian Climates: Comparative Modelling And Sensitivity Analysis – Addendum, January 2022, Alan Green, Paul Cooper

Faculty of Engineering and Information Sciences - Papers: Part B

This document has been prepared as an addendum to the report ‘Hygrothermal Performance of Vapour-Permeable Wall Membranes in Cooler Australian Climates: Comparative Modelling and Sensitivity Analysis’ [1] prepared by the Sustainable Buildings Research Centre (SBRC) at the University of Wollongong under the auspices of the Australian Research Council Hub for Australian Steel Innovation. It includes results from an additional set of hygrothermal simulations, as well as further explanation of certain assumptions in the original report.
