Daniel Krenn and Annika Wille received their habilitation certificate

This year, two colleagues at our faculty defended successfully their habilitation thesis. Daniel Krenn, Department of Mathematics, received the venia docendi in Mathematics, and Annika Wille, Department of Mathematics Education, the venia docendi for Mathematics Education. The certificate was presented on June 17 by the Dean Gerhard Friedrich and the Vice Dean Clemens Heuberger.

Congratulations to our young colleagues for their excellent work and contributions to the field of Mathematics and Mathematics education!

New research project on spreadsheet errors (FWF / iDEOS)

Spreadsheets based on Microsoft Excel are omnipresent in most organizations. Errors in these spreadsheets can however be highly problematic and a number of examples exist where wrong calculations led to severe financial loss for companies. A new joint project between researchers of AAU and TU Graz will address these problems and develop novel means that help users to detect and remove errors from spreadsheets.

The research project “Interactive Spreadsheet Debugging (iDEOS)” is funded by the Austrian Science Fund (FWF) and will be led by Prof. Dietmar Jannach of the Department of Applied Informatics.

More information about debugging spreadsheets can be found in this research article.

We are looking for a doctoral student (75%) and a postdoctoral researcher (100%). Please contact Prof. Jannach in case you are interested. The project will last 3.5 years.

Generating images of ice and water on aircraft wings

Juliana Padilha Leitzke came to Klagenfurt from Brazil in order to write her doctoral thesis and to contribute to reducing the risk of undetected hazardous ice on aircraft wings. She expects to complete her doctoral thesis shortly.

New technology to determine ice on aircraft

In-flight icing of aircraft wings represents one of the biggest safety risks in aviation. Researchers have developed new wireless sensors allowing improved detection of ice formation. Read more

Using mathematics to improve rail cargo planning

Every year, around 8,400 employees transport more than 100 million tonnes of goods on behalf of Rail Cargo Austria. 620 traction units and 21,500 goods wagons are required purely for rail cargo operations. In the case of highly complex logistics tasks such as this, the deployment of man and machine requires careful planning. Mathematicians working on a project funded by FFG are now developing algorithms designed to significantly enhance the planning process.

Pursuing the research objective of a more unified and democratic social media ecosystem

Facebook, Twitter and Co. are centralised platforms that are owned by private corporations and that control the respective networks unilaterally. An international project financed by EU-H2020 under the project leadership of Radu Prodan (University of Klagenfurt) aims to create a decentralised social media ecosystem using blockchain technology.

Finding faults in Excel

A familiar situation for many: A large Excel file that includes many sheets, rows and columns – and in the end, the correct result stubbornly refuses to materialize. Troubleshooting can be complicated whenever numerous formulas and references are involved. Patrick Koch is working on the project “Debugging of spreadsheet programs (DEOS)”, funded by the FWF, which aims to simplify the search for errors. He recently received the “ACM SIGSOFT Distinguished Paper Award” for his publication on this subject.
