Using a chatbot in discord to facilitate student learning

Textual data contains a large amount of information which is embedded. This text information is easily extracted by humans but is difficult for machines to interpret. Using various textual analysis methods some information can be drawn out from pieces of text.The Discord platform is a widely used communication tool, which offers the ability to develop bots to engage with it’s users. This has been minimally explored in the education space.

Effect of VR construction tours on potential engineering and construction management students

Selecting a study topic and career path highly depends on perception of the profession among high school students and their parents. A lack of good understanding of career options and pathways often limits the choice. QUT has developed a VR based introduction to Construction and has performed surveys on high school students to investigate its impact. This project looks to analyse these surveys and to come up with future efforts to ensure that high school students can make a better …

Polymer hydrogels as wound dressings

Polymer hydrogels make ideal wound dressings. They are crosslinked networks with high water content and can used as topical dressings on the eyes to deliver small molecule drugs. This project will investigate hydrogels made from seaweed extracts as tough but flexible sheets with high water content. The hydrogel sheets will have cooling effects when placed on the skin and be able to delivery small molecule drugs.

Sampling to optimise training data

Training data is needed for fitting supervised machine learning models but may not always be plentiful, especially when labelling needs to be performed manually. In such a situation we may wish to target the new sample cases to be labelled to improve model performance for the least additional resource.In this project we’ll look at how active learning techniques - techniques which make use of the model outcomes – can be used to effectively determine a sampling strategy.

SECAN - Semi-continuum method software improvement and comparison with other bridge deck analyses

There exist a number of methods for bridge deck analysis, e.g. grillage analysis, finite element analysis.SECAN is a software based on Semi-continuum method for bridge deck analysis. Its latest version is developed using MicrosoftVisual Studio.This project aims to improve the software for comparison with other bridge deck analyses.

Keeping carbon – ensuring soil carbon gains through improved grazing management persist through drought in Australia's tropical and semi-arid grasslands

Drought is the biggest barrier to sequestering soil organic carbon (SOC) in soils over the long-term. While options are limited during dry periods, how we manage our pastures prior to drought can influence the resilience of SOC to losses and enhance recovery.

Using time-controlled grazing to sequester carbon in Queensland rangelands

Time-controlled grazing (TCG), or cell grazing is a management strategy in which cattle are stocked and rotated across small paddocks or “cells” according to fodder availability. Grazing takes place in short durations at high stocking densities, in an effort to mimic the grazing patterns of wild ungulate herds.This management strategy has gained traction in recent years due to claims that it improves both pasture productivity and diversity, whilst also increasing long-term carbon pools. Limited data is available on the impact …

Co-benefits of trees on farms: soil carbon

Soils are now in the ‘front line’ of global environmental change. Soils are the largest global pool of actively cycling organic C and N. Maintaining and increasing soil organic matter (SOM) is a prominent strategy for mitigating atmospheric CO2 and adapting agriculture to climate change.At the same time the global biodiversity crisis has led to increased scrutiny on supply chains to scrutinise farms ecological footprint. Planting or retaining trees in the landscape has the opportunity to achieve both outcomes, however …

Accuracy of measuring surface roughness using image processing

Our team’s research focusses on developing antibacterial and antiviral surfaces for various applications such as orthopaedic and dental implants, general surfaces such as lift buttons, handrails, taps, switches, benches etc. These antibacterial and antiviral surfaces are generated on a variety of materials using various techniques such as hydrothermal synthesis, electron beam lithography, anodization and wet etching. By implementing these surfaces on implants, medical devices, surgical tools and general hospital surfaces, we can reduce the spread of infection, saving lives. Surface …

Flexible thermoelectrics for wearable electronics

Advancements in miniaturisation and integration of electronics have recently stimulated the explosive progress in wearable electronics. With increasing practical needs, our analysis has indicated that the market values of wearable electronics are predicted to boost up to US$50B in 2022 and US$72B in 2026. Currently, conventional batteries have limited applications in wearable electronics due to their requirements of frequent replacement/recharge and extra-maintenance. This is especially true in temperature or pressure sensors in some circumstances such as remote-control smart home systems …

Creation of adsorbent beads for ion exchange using green chemistry

Commercially available ion-exchange resins are effective adsorbents for a variety of systems with high cation exchange capacity, regeneration efficiency and chemical stability. These resins are typically derived from anthropogenic (human made) sources such as crude oil.In order to support the greening of industrial processes, research into renewable and environmentally-friendly alternatives is required.This project aims to investigate the spherication of adsorbent powders with bio-polymers for use in an industrial chemistry/process engineering setting.
