When a video call stutters, an online game lags, or a webpage feels slow, internet speed is not always the problem. More often, the issue is network delays, known as latency. In his doctoral thesis, Simon Sundberg investigates how such delays arise and develops new methods for measuring them.
Most people associate network performance with bandwidth, that is, the amount of data that can be transferred per second.
Karlstad University has been awarded SEK 11.5 million from the Swedish Energy Agency and Region Värmland as the SOLVE research centre enters a new five-year phase. The investment will contribute to the development of future solar energy systems and support Sweden’s transition towards a more sustainable energy system.
SOLVE brings together universities, businesses and public-sector organisations in research aimed at enabling a faster expansion of solar energy in Sweden.
On 7 September, representatives from the Knowledge Foundation (KK-stiftelsen) visited Karlstad University to gain deeper insight into how the university collaborates with industry in research and education.
When you enter a web address into your browser and arrive at the correct website a second later, a process takes place that most people never notice. Behind the scenes, one of the internet's most important systems is at work: DNS, the Domain Name System.
I juni disputerade Mario Setta vid Karlstads universitet med sin doktorsavhandling i matematik: Boundary-Aware and Multiscale Methods for Topology Optimization.
What if your heat pump knew when you were about to take a shower or use large amounts of hot water? It could then produce hot water at the right time instead of heating unnecessarily. This idea lies at the heart of the research conducted by industrial PhD student Manal Rahal at Thermia, where machine learning is being used to make heat pumps smarter and more energy efficient.
Today, many heat pumps are controlled using fixed rules and pre-set threshold values.
With a background as a researcher, senior lecturer and Head of Department, Daniel Olsson is taking on the role of leading the Faculty of Health, Science and Technology. For Daniel Olsson, leadership is about creating the conditions that enable others to succeed.
"I enjoy working with development and leadership issues.
It has now been decided which innovators will represent Värmland at the national SKAPA Award ceremony in Stockholm in November. Birgitta Persdotter, a researcher in social work and creator of Vaves®, has been named the winner of the 2026 SKAPA Award Värmland.
Japan attracts doctoral students from around the world, both as a host country and as a hub for international exchange. For Dide Dijkers from Karlstad University and Alireza Niknam Khajepasha from Hiroshima University, academic mobility has meant exposure to new research environments and striking cultural contrasts.
Dide Dijkers is currently undertaking a five-month exchange at Tohoku University in Sendai.
Karlstad University is launching a new Robot Camp for children this summer – an initiative that quickly became fully booked. Over two weeks, participants get to explore the possibilities of technology by building and programming their own robots in a creative and collaborative environment.
The Robot Camp combines technology, programming, collaboration, and problem-solving and is part of Teknikerjakten (The Technology Hunt).
Karlstad University is participating in the new EU-funded project SPECTRA, coordinated by Ergang Wang at Chalmers University of Technology. SPECTRA aims to develop new technologies in which solar energy is used to convert plastic waste into valuable resources.
Within the project, Karlstad University will develop computational and AI-assisted tools to accelerate the discovery and optimisation of materials and processes.
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.
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.
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.
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.
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.
