New thesis on how AI can make apps more user-friendly
How can apps and digital health services become easier to use for older adults and people with motor impairments? In his doctoral thesis, Bilal Maqbool in Computer Science has developed an AI-based method that can imitate user interactions and has investigated why usability testing is often a challenge.
”To create user-friendly systems, developers need to test their products with real users. This can be difficult, especially when the target group includes people with conditions such as Parkinson’s disease, reduced motor function, or other health challenges. Recruiting participants, obtaining ethical approvals, and conducting repeated tests require both time and resources”, he says.

Karlstad University part of Electrified Flexible Industry
Three units at Karlstad University – Electrical Engineering, DAMI and Computer Science – are part of the large-scale project Electrified Flexible Industry. The aim of the project is to develop solutions for a more flexible, resilient, digital and resource-efficient energy system.
Karlstad University’s role in the project is to develop AI-based solutions to enable companies to anticipate energy demand, prices and flexibility opportunities. This, in turn, will help companies reduce costs while contributing to a more sustainable energy system.
“We will combine AI with energy data to enable smarter decision-making around energy utilization,” says Andreas Theocharis, Associate Professor in Electrical Engineering and project leader for Karlstad University’s contribution to Electrified Flexible Industry.

New funding for cybersecurity graduate school
Karlstad University has been awarded continued funding to further develop and expand the Swedish Graduate School for Cybersecurity (SIGS-CyberSec).
The initiative is one of three industrial graduate schools receiving support from the Knowledge Foundation (KK Foundation).
– The new funding will enable the graduate school to recruit seven additional industrial doctoral students. The aim is to strengthen both research capacity and skills provision in cybersecurity for Swedish companies, a field where the demand for highly qualified expertise is growing rapidly, says Simone Fischer-Hübner, professor at Computer Science and Project Manager for SIGS-CyberSec.

Efficient and sustainable organic solar cells
Organic solar cells are highlighted as a promising future technology. They are flexible, lightweight and can be manufactured at low cost in large volumes. In recent years, their efficiency has surpassed 20 per cent. However, despite this progress, a crucial challenge remains: lifetime.
In a new doctoral thesis at Karlstad University, Suraj Prasad shows why the materials degrade and how the problem can be addressed.
“We already have high efficiency. The main challenge now is to make the solar cells last,” says Suraj Prasad.
Light and oxygen trigger degradation
In the study, organic solar cell materials were exposed to simulated sunlight in air. The results show that degradation is driven by chemical reactions in which oxygen plays a central role.

Leading close to the patient presents challenges for nurses in municipal home healthcare
Time constraints, inadequate organizational conditions and insufficient collaboration create challenges for nurses leading the care of older adults in municipal home healthcare. This is shown in new research from Karlstad University.
In her doctoral thesis, Erica Lillsjö explored nurses’ patient-centred leadership in municipal home healthcare for older people. The findings show that nurses in municipal home healthcare strive to lead with a focus on the older person’s wishes, needs and best interests, while also seeking to create a sense of security for both the older person and their relatives.
– The nurses wanted to lead, and they wanted to lead in ways that promote person-centred care. However, the organizational conditions created challenges for their leadership, says Erica Lillsjö.
