Karlstad University has research equipment in several places in its premises. Now it could also be found outdoors. Since February, a Starlink antenna has been installed on the roof of the building where the Computer Science researchers are located.
How reliable are different methods for connecting to mobile networks to support train signaling systems? This is what Professor Anna Brunström and Associate Professor Johan Garcia at Karlstad University have investigated in collaboration with DRIVE partner Icomera.
As part of the DRIVE project, real life measurements of 5G networks are now taking place in Rome, Italy, where two large mobile operators are up to proof in terms of coverage, connectivity, latency and throughput performance.
In Dec. 2020 - Jan.
In the DRIVE project, a common test environment with industry partner Varnish Software has now been installed. The tests will measure the impact of different network connections on latency and bandwidth during video streaming.
Since mid-December, latency and bandwidth testing has been ongoing in Karlstad University's 5G testbed. A server is connected to several network connections at the same time to compare their performance.
Digital Well Arena is a collaborative initiative on digital solutions for a healthier life, between the public sector, academia, civil society, entrepreneurs and business in Värmland. Recently, a workshop was held to make an inventory of the needs for digitalisation in the healthcare sector, what problems society and individuals would benefit from having solved.
On November 16-17, the DRIVE project held a two-day kick-off meeting at Karlstad University. The aim for the kick-off was to get the DRIVE and its subprojects officially started and to let all partner representatives and researchers meet face-to-face.
- I am very excited to get started!
Computer Science at Karlstad university is welcoming Red Hat as a new partner within the DRIVE project. Red Hat is a global software company that provides Linux based open source software products to enterprises. This includes hybrid cloud infrastructure, middleware, agile integration, cloud-native application development, and management and automation solutions.
On September 13, the first DAMI workshop was held at Karlstad University. The aim for the workshop was to launch the DAMI working groups and disseminate the center and its activities to a wider audience.
- The technical purpose of the workshop was to exchange information and ideas about recent developments in the area of digitalization for complex manufacturing, says Andreas Kassler, professor in computer science at Karlstad University.
The digitalisation of both industry and the wider society has only just begun. Communication technology and cellular networks are key factors for the digital transformation and will shape our lives in the coming decade. The project DRIVE has just been launched at Karlstad University and it will last eight years.
Latency is the delay that occur in digital services when they are connected online.
The digitalisation of society has led to a constant pursuit of better performance. Through a new research project, Computer Science at Karlstad University wants to help speed up the process.
Waiting for changes in the major operating systems Linux and Windows is time-consuming.
DigitalWell Arena and Karlstad University have, together with Telia, built a test environment for businesses, entrepreneurs and others who are developing innovative new services.
5G is the fifth generation of mobile communication systems, which enables higher capacity and bandwith, as well as shorter response time and latency. The improvements facilitate the development of services within healthcare, industry and gaming.
Karlstad University and Deutsche Telekom are collaborating on a project intended to improve the internet connection for users. The goal is for the technology to be incorporated into every mobile phone within five years.
Mobile phones use 4G, 5G, and Wi-Fi to access the internet. The project called MultiAccess will tie them together in a flexible way and thus improve the connection.
Knowing how long stored carbon dioxide stays in the ground or how the groundwater flows below the ground surface are difficult questions to answer. Mathematical calculations often become so complicated that computers cannot handle them.
This kind of research began in the 1970s when oil and gas were to be extracted in the North Atlantic.
The overall goal for HITS was to contribute to the development of high-quality networked services for a mobile world through world-class research and industrial collaboration.
Steam engines, electrification, and CNC – three seminal events in industrial history. These days, digitisation is putting pressure on the industry. With the new research centre called DAMI4.0, Karlstad University will be ready to meet the industry’s demands for new technology.
Noisy steam engines and welding robots have made a huge difference to industrial development.
Patrick Murmann's research is about creating useful technology to help users of mobile fitness and exercise applications understand how the personal information they share is and will be processed.
Patrick Murmann, can you put your research in a context?
- My research deals with creating usable technology that helps users of fitness tracking devices understand how the data they share with their respective online service have been and will be processed.
How aware are you of the privacy decisions you make online? In the thesis “Homo Varius: Investigating Intrinsic and Extrinsic Determinants to Explain Online Privacy Decisions”, Agnieszka Kitkowska has looked into how we can become more aware of our decisions and the importance of interface.
In computer science, heuristics are a way of making smart assumptions that in turn help to find solutions to a problem.
Nurul Momen, doctoral student at the Department of Computer Science at Karlstad University, has investigated whether apps’ data access takes user integrity into account.
Let’s say, purely hypothetically, that there is an app for washing your hands. You start it for the first time and an interface shows on the screen saying: “Permission required to access water”. You press “Allow” and use the app to wash your hands.
