Gavin Dollman is involved in virtual prospecting for fossils using a drone.

Gavin Dollman is one of the young researchers selected for the international research programme funded through the US-SA Higher Education Network. This prestigious programme is aimed at giving PhD candidates and their supervisors the opportunity to regularly travel to the USA and spend time at participating US universities where their co-promoters will be based.

“The University Staff Doctoral Programme (USDP) has allowed me to bring my idea of collaborative science to fruition. It’s an exciting opportunity,” Dollman said.

Dollman added that his PhD studies would focus on the machine and deep learning for prospecting for palaeontology. He is studying with the Appalachian State University. Other participating universities are Montana and Colorado State.

He has also had the privilege to work alongside a team of Geologists and Paleontologists from the universities of Birmingham, Zurich and Oxford in a project under the auspices of the University of the Witwatersrand’s Evolution Studies Institute (ESI) on a site in rural Eastern Cape.

“My role within this massive project is to perform a detailed survey of the sites and the surrounding area for later analysis. I used a drone known as the DJI Phantom 3 Pro with which I took hundreds of pictures that were later put together to create a detailed map,” he said.

“The maps allowed for virtual prospecting by the team and will in the long term serve as the basis for a predictive fossil model for the area.”

Dollman is a lecturer in the Department of Computer Science and Informatics on the Qwaqwa Campus.

Music lecturer’s innovative app is a first in South Africa
2014-07-24

Dr Frelét de Villiers, lecturer at the Odeion School of Music (OSM) at the University of the Free State (UFS), is in the process of developing an innovative interactive mobile music application – Notes&Fun.

Notes&Fun is being designed to assist aspirant pianists. It will support beginners with notation and rhythmic patterns.

The app will display single notes, phrases or rhythmical patterns on the phone or tablet and then apply the built-in microphone to measure the frequency of the notes played on the piano itself. It will indicate whether you’ve played correctly, or if you have made a mistake, the correct note will be displayed. Notes&Fun consists of multiple levels, each with a practise and test mode that gradually increases in difficulty and complexity. As opposed to existing apps, Notes&Fun is conceptualised with immediate pitch detection and is applied with a real (acoustic) piano.

For the pilot phase of this initiative, the developing company Maxxor in Cape Town will create a demo app which can be downloaded for testing purposes and general feedback. Once the developing company and innovator are satisfied with the first phase, the product will be marketed vigorously on social media. The initial app will be free, but subsequent levels will need to be purchased. The developers will start a Facebook page where users of the app can add their latest scores and compete with other users. Initially the app will only be available on the Google Play Store due to the fact that more people own Android devices than Apple products. Once the product has proven to be financially viable, the developers will adapt it for the Mac App Store as well.

“The beauty of this app is that music has a universal language, so it can be marketed internationally and I am privileged to have the institutional support from the UFS Technology Unit regarding the judicial process and developing process of the product,” Dr De Villiers said.
