Mathematics supports new medical imaging techniques

/in , , , , , /by

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

/in , , , , , , /by

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.

Enabling drones to fly long-durations autonomously

/in , , , , , /by

In practical settings, ten minutes of flight time are generally not enough for most applications. A team comprised of researchers from the University of Klagenfurt (AAU) and NASA-JPL/California is working on ways to enable the autonomous flight of drones in several stages with intermittent charging phases. Christian Brommer, AAU doctoral student, has recently published the results of his research.

Tool-assisted Fault Discovery in Knowledge Bases: A Novel Approach from Klagenfurt

/in , , /by

Artificial intelligence systems — for instance, in biomedicine — are often based on knowledge bases, which store expert knowledge in machine readable form. Unfortunately, it is not uncommon that mistakes creep in while knowledge bases are created. Such mistakes can have serious consequences, for example, if the system suggests a wrong medication for a patient. Finding such faults is, however, a very hard task, often just because of the sheer size of the knowledge bases.

For this reason, a team of researchers from the Department of Applied Informatics has developed the “OntoDebug” tool, which is used by people from all over the world. In an article that was recently published in the prestigious “Knowledge-Based Systems” journal, the usefulness of this tool could be scientifically validated by means of several user studies. In particular, it was shown that the effort needed for the discovery of faults in knowledge bases is significantly reduced when OntoDebug is used.

New cooperative FFG research project: AYUDO

/in , /by

The project AYUDO (Spanish: „I assist”) aims to support elderly or chronically ill people by digitizing their health data in order to be able to take early and regular measures to preserve or improve their health. The focus is on recording and supporting one’s own management of those factors that have a positive effect on physical and mental well-being and influence one’s own performance and resilience.

An integrated personal digital health record with health data from the medical and domestic environment currently does not exist in Austria.  AYUDO would like to realize exactly this and integrate already distributed stored digital health data, such as vital data, lifestyle data, wellbeing data or also medication, intake or findings data of an elderly or chronically ill person in the longer term in his/her ‘Personal Digital Health File’. This ‘collection’ should also be continuously supplemented as barrier-free as possible through new, intelligent services for personal health management.

Interoperability and data security play an important role in the architecture of the planned technical solution. Interfaces to user’s individual digital data sources should be flexibly adaptable. It should also be possible to supplement health data that is not digitally available as barrier-free as possible via suitable user interfaces.

In addition to conventional interaction models, natural language interaction models are also to be developed. The aim is to investigate the acceptance and security of these blended solutions for the AAL sector. End users will be strongly involved in development and evaluation activities.

AYUDO aims to increase the quality of life of elderly, chronically ill or multimorbid people by improving their self-assessment of their own state of health and self-prevention. If desired, access rights to AYUDO services can also be transferred to the social environment (care and nursing). We expect new findings and results in particular in the following areas:

  • use cases of a personal digital health record through new intelligent services;
  • application, acceptance and security of (blended) digital language assistance for AAL solutions;
  • helpful communication/visualization of health data for patients and caregivers;
  • flexible integration of individually already available, distributed, inhomogeneous, non-integrated and incomplete digitalized health data;

project start: October 2019 – September 2022
