Simulating cyber-physical threats to the City of Vienna

A large number of critical infrastructure facilities are located in cities and their surroundings, providing essential services in a compact geographical space and resulting in mutual physical and logical dependencies. The provision of services such as electricity, gas, water, communication, food, fuel, road or rail, in particular, is achieved by operating extensive networks. In the FFG-funded project ODYSSEUS, Stefan Rass (Institute of Applied Informatics) and his team are working on developing a framework for a simulation designed to forecast the consequences of attacks on such interlinked infrastructure facilities.

Europe’s largest Dronehall is open for business

Researchers investigating autonomous drones can now use a cutting-edge research infrastructure at the University of Klagenfurt, measuring up to 150 square meters and a height of ten meters. This is a tremendous boost for the “Drone-Hub Klagenfurt”, already known for hosting some of the world’s top players in the field.

Automatic analysis of eye surgery

In many cases, modern ophthalmic surgery involves the video recording of surgical proceedings. The video material is either used for training purposes or for the subsequent reconstruction of operation sequences. Klaus Schöffmann has assembled a research team to work on the automatic recognition of relevant sequences within the scope of an FWF-funded project. Natalia Sokolova, a doctoral candidate at the Department of Information Technology, is a member of the project team and her work focuses on improving the search for particularly “relevant” surgical phases.

Are we seeing genuine progress with recommender systems?

Recommender systems represent a key technology for e-commerce providers such as Google, Amazon, Netflix, Booking.com and Spotify. It is therefore with a certain urgency that researchers are working intensively on making ever more accurate predictions about the products and services users might want to consume next. However, in a paper published recently, Maurizio Ferrari Dacrema, Paolo Cremonesi and Dietmar Jannach were able to show that several critical issues concerning the research methodology are hindering progress in the development of recommender systems. In recognition of their work, they received the Best Full Paper Award at the renowned ACM Conference on Recommender Systems in Copenhagen in September.

The University of Klagenfurt makes the first professorial appointment to the Digital Age Research Center (D!ARC): Elisabeth Oswald, who specializes in researching cybersecurity, arrives in Klagenfurt

Step by step, the University of Klagenfurt is steadily expanding its activities in the new research area “Humans in the Digital Age”. The appointment of Elisabeth Oswald (University of Bristol) represents an important milestone in this endeavour. As an applied cryptographer, Elisabeth Oswald works at the interface between mathematics and computer science. In her research, she focuses especially on the cryptographic aspects of cybersecurity.

Mathematics supports new medical imaging techniques

While MRI, CT and x-ray already provide valuable insights into the interior of the body, the technology involving so-called magnetic particle imaging now promises new possibilities with high resolution, less acquisition time and no harmful radiation. In order to be able to draw conclusions about biological processes based on the observation of magnetic particles in a magnetic field, research has to rely on mathematics. Tram Thi Ngoc Nguyen is completing her doctoral thesis on this topic at the University of Klagenfurt.

Using existing cellular networks for drones

It might soon become common for drones to transport goods and people, monitor disaster zones, and bring various forms of relief to areas that are difficult to access. Which communication infrastructure is best suited to facilitate this? Researchers at the University of Klagenfurt have explored potential challenges associated with the use of traditional cellular networks.

Expanding the sensory skills of machines

Machines are already capable of many things. A certain set of sensors has already been fully developed. And yet, Harald Gietler, researcher at the Department of Smart Systems Technologies seeks to discover: “Who knows what kinds of sensors we will need in the future?” He is currently developing a new technology, which will allow machines to determine the location of other machines.

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.
