    Process modelling for more efficient pulp and paper manufacturing

    Integrated paperboard manufacturing consists of a number of unit processes that continuously generate large amounts of process data. Manufacturing is energy-intensive and variations must be taken into account to achieve the optimal production process. A new thesis at Karlstad University shows how different mathematical models can be applied to the processes in aspects of improved product quality and reduced energy use.

    “I have studied the conditions that exist for statistical and mechanistic models for predicting pulp and paperboard properties and for increased energy efficiency”, says Daniel Ekbåge, who successfully defended his doctoral thesis on process modelling in pulp and paper manufacturing.

    The university remains partially open

    The mixed form of teaching will continue to apply during the spring term 2021. Priority will be given to first-year students enrolled in campus-based programmes at undergraduate and master’s level, as well as activities involving international students, following a new decision effective from 26 October 2020 on continuing to keep campus partially open.

    Programme coordinators will be asked to identify courses where on-campus teaching would be possible with regard to the Public Health Agency’s recommendations. Course components that are crucial for the students’ progression and that must take place on campus and examinations that cannot be turned into a take-home examination will be prioritised next, regardless of when in the course or programme they take place. Planning for study period 5 will not be affected by the decision but remains the same.

    Excessive data access from apps – a threat to individual privacy

    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. When you are done, you put the phone back in your pocket. But now you are not sure whether you remembered to revoked the permission to access water. Is it still running?

    Analysis method crucial for correct results in coronavirus research

    Researchers in analytical chemistry at Karlstad University have published an article on the analysis of how the coronavirus attaches to receptors in the human body. They argue that existing research in the field has drawn incorrect conclusions due to simplified calculation methods.

    “We were interested in using our new advanced method of calculating interactions on surfaces, which Patrik Forssén, doctor of data processing, developed in collaboration with us to contribute to a better understanding of the infection mechanisms of Covid-19”, says Torgny Fornstedt, professor of analytical chemistry. “However, we were not able to perform Covid-19 experiments at short notice, including taking into account all safety aspects, and we also needed a test case for research applications.”

    Automation of the heavy metal industry

    Digitalisation has proven to be an effective way to reduce the number of errors in the production stage. The new technology has mainly been used in, for example, the car manufacturing industry. In a new project, researchers at Karlstad University are looking at the really heavy metal industry where manual work is still common.

    Forging processes in the heavy metal industry consist of many manual processes where an error may result in costly stops in production. Automating the various steps with the help of mechanical and materials engineering, secure data processing and the Internet of Things is the main focus of the research project “Smart Forge – sustainable production through AI controlled forging oven”.

    EU award shows good conditions for researchers at Karlstad University

    The HR Excellence in Research Award granted by the European Commission is proof that we are successful in creating a stimulating working environment and excellent conditions for our researchers. The award also guarantees our commitment to fair and transparent recruitment, as well as favourable professional development for researchers.

    - Our application, which has now been granted, will be used to make it clear to researchers outside of Sweden that Karlstad University is a safe and well-organised university that allows researchers to develop under excellent conditions, says Vice-Chancellor Johan Sterte.
