    New platform facilitates the use of machine learning in NFV optimization

    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. This platform helps researchers and industry working on Network Functions Virtualization (NFV) to extract information from underlying infrastructure to optimize latency, costs and energy consumption.

    “This tool saves a lot of time and makes NFV researchers’ work much easier,” says Michel Gokan Khan. “If you want to do it yourself, you need to manually run different tests many times and it will take months to prepare and process all the results.”

    Michel, who has worked in the industry for many years, saw an opportunity to apply his programming skills in the project. During the first months of his doctoral studies, he developed the NFV-Inspector.

    Students develop app for new type of cultural experience

    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. Together they have created a new type of cultural experience in which a smartphone interacts with the contents and for example vibrates in time with heartbeats, becomes warm during a heated dialogue or sends links related to the podcast contents.

    “The aim is to offer an art form that everyone with a smartphone can enjoy. I wanted to integrate the contents with effects to reinforce the listening experience,” says Amanda Fromell, dramatist and doctoral student at the Department of Drama and Theatre Arts at the University of Birmingham.
    “I have long been interested in how algorithms affect phone users. This project also allows users to see which control phones exert over us.”

    Less latency with smarter WiFi

    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. The quality is not always great, but performance can be improved by directing data streams in smarter ways. In this way, the queueing that results in extra latency in WiFi networks can be avoided,” says Toke Høiland-Jørgensen, who recently obtained his doctorate in Computer Science from Karlstad University.

    Researchers met helthcare developers at this year's Research Vernissage

    “I lead the DigitalWell Research project that aims to enhance the development of digital welfare services. Meeting people from businesses and organisations at a vernissage was interesting and different,” says Stefan Alfredsson, a computer scientist from Karlstad University.

    DigitalWell Research will create an innovation environment in which small and medium-sized businesses develop digital welfare services in close cooperation with researchers and the public sector.

    Major investment in the development of digital welfare services

    DigitalWell Arena, a Värmland-based project that includes Computer Science at Karlstad University, is one of the winners of Vinnova’s Vinnväxt competition. Over 10 years, SEK 148 million will be invested in the development of digital welfare services. The aim is to make it easy for all residents to prevent illness and receive the necessary support regarding health issues.

    Through the Academy for Smart Specialisation and Vinnova, Karlstad University is granted around SEK 26 million for the initial three-year phase. The funding is shared by the Computer Science research group, the Service Research Center (CTF), Nursing, the Centre for Gender Studies (CGF) and the Grants and Innovation Office.

    “It is fantastic that we as a university can contribute to the development of welfare service through excellent research. I think this will also be positive for recruiting researchers to our research groups,” says Vice-Chancellor Johan Sterte.
