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.
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.
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.
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.
Many companies in Sweden and Norway are already testing circular solutions such as take-back systems, repair and reuse, but few succeed in scaling them up. A new project at the Service Research Center (CTF) at Karlstad University will help companies move from pilot initiatives to viable business models.
– What is missing today is not technology, but workable business arrangements around it.
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 gifted students be both challenged and supported in developing their skills in technology studies? A new study at Karlstad University shows that the subject of technology has strong potential to meet gifted students’ needs through modeling using digital tools.
Recently, two successful trials were conducted within the 6G-PATH research project, where nursing students and ambulance personnel tested a new form of remote healthcare education.
The aim was to investigate how next-generation communication technologies such as 5G, future 6G networks, edge computing, and cloud services can be used to create realistic and accessible learning environments for healthcare professionals.During the trials, students participated in simulated e
This autumn, Sweden will hold elections, and it is time for the country’s citizens to take part in one of the privileges of living in a democracy. This is especially true for young people who may have the opportunity to vote for the first time. However, leading discussions in a classroom within the subject of social studies can be challenging in a turbulent political climate marked by increasing polarization.
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.
What can ghosts tell us about justice, history and the future? This is what Judith Tesfaye Kiros, PhD in English, has explored in her thesis Ghosts of the Black Atlantic: Hauntology and the Temporality of Justice in Black British Poetry.
Judith Tesfaye Kiros has analysed the work of four black British poets in relation to haunting as both a theme and an ethical concept.
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 EU-funded project PIONEERS-6G (Platform and Device Innovations for Energy-Efficient, Resilient, and Secure 6G IoT Systems), coordinated by Karlstad University, has officially kicked off.
Over two days, all project partners gathered at Karlstad University to establish the framework for the work ahead.
– It was very valuable to meet all the partners and get to know each other better.
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.
