Is it possible to improve the performance of mobile data communication through a combination of technologies such as WiFi with 4G and 5G? This is what Stefan Alfredsson, senior lecturer in Computer Science, would like to find out in his research.
It is hard to imagine life without a mobile phone. It is our primary access point to social media and the authorities and offers a constant link to entertainment, shopping, and important community services.
In Brazil, 63% of the population receives primary health care at home, and the introduction of digital aids has revolutionized healthcare. Forms that were usually completed by hand can now be easily filled out using a mobile application. At the same time, there are requirements that patient data must be processed securely.
Apps have become an important part of our lives. They guide us to the right address, tell us to exercise more, and provide us with information about other things that we need help with in our everyday lives. In order to be able to do so, they register where we are, what we say, and what we do. But can we really trust the apps with our personal information?
Mobile broadband gives 30% lower performance than normal broadband. This is shown in a new study presented by Karlstad researcher Mohammad Rajiullah at The Web Conference 2019, a top-ranked (A*) conference held on the 13th –17th May in San Francisco, USA.
Smartphones and mobile broadband have revolutionised web use.
Face and voice recognition, cancer detection algorithms, autonomous cars and many other technological innovations have made artificial intelligence (AI) a hot topic.
SQuaD (Software Quality and Digital Modernisation) is the new name of what used to be called SERG (the Software Engineering Research Group), one of the three research areas in Computer Science at Karlstad University.
"We are, of course, still software engineers at heart.
Computer Science at Karlstad University is now recruiting four new doctoral students. Three of the projects are focused on the development of digital healthcare services and one on reinforcing the department’s work on cloud services.
DigitalWell Arena is a large investment in the development of digital healthcare services.
Now there is a clear definition of internet access. Computer Science at Karlstad University was one of the participants in a project in which the Swedish Internet Foundation (IIS) and Netnod brought together service providers, technicians and other interested parties to define important terms so that they can be used consistently.
"Today all our services rely on internet access.
This week, 29 April - 2 May, the 39th version of the IEEE Infocom conference is taking place in Paris, France. The conference is one of the leading conferences in the computer networking area and attracts a large number of researchers from all over the world.
Four students on the Master of Science in Engineering programme helped to develop Dysconnect, an app with podcast dramas that enhance the listening experience through interactive effects. The app was presented for the first time to the public at a cultural festival in Scotland over the weekend.
Hello there Martin Wahlberg, student and app developer! You have just come home from a cultural festival in Scotland.
At his inaugural lecture as associate professor on 5 April, Sebastian Herold described his software development research and the challenges faced in this area.
“When you build a house you have a plan and the builders follow acknowledged building practices. This is less standardized in software engineering,” says Sebastian Herold, the latest associate professor in Computer Science.
Guaranteeing that information does not leak is one of the challenges of centralising logs. Researchers at Karlstad University have now developed a technical solution for transporting logs via cloud services in a simple, secure way.
“There are different techniques for protecting logs when they are centralised. One could for example encrypt them, verify that nobody has changed them, and verify that the logs come from a specific device.
Karlstad University is the only Swedish university participating in a new large European research and innovation project under Horizon 2020. The aim of the project is to enhance cybersecurity skills in Europe.
“We have a high profile in security and integrity protection techniques.
From this autumn, Karlstad University is offering a new three-year study programme in computer science for those who like IT and programming, but who are not interested in studying physics, electronics or a lot of mathematics.
“The programme is tailor-made for those who completed upper-secondary school programmes in Science and Technology,” says Tobias Pulls, coordinator of the new programme.
Michel Gokan Khan, PhD student in Computer Science at Karlstad University, has developed the “NFV-Inspector”, a free and fully open source platform for optimizing the infrastructure of the next generation of 5G networks.
Podcast dramas that enhance the listening experience through interactive effects have become reality through a collaboration between dramatist Amanda Fromell and computer technology students at Karlstad University.
Choppy Skype calls and films on Netflix that suddenly start buffering. Such types of latency can be extremely irritating, but will soon become a thing of the past. Toke Høiland-Jørgensen, researcher at Karlstad University, has developed a solution for smarter WiFi that may soon be in all our homes.
“WiFi technology is used everywhere because it is cheap and simple.
Several Computer Science researchers and students have received nice awards at conferences during November. Congratulations to:
• Nurul Momen, who received the Best Poster Award at NordSec in Oslo. The title of the poster is “User Perception Analysis for Showing Personal Data Access as Privacy Implication Factor”.
• Dejene Boru Oljira, who received the Best Paper Award at Networks of the Future in Poznan.
