Computer science

Computer science is about developing and analyzing concepts, models, methods and tools in order to make programming and computer usage easier, more reliable and efficient.

At BTH there are several different approaches to research in computer science, such as intelligent transportation systems, security, distributed systems and informatics/applied systems science.

Intelligent transportation systems

Research in the field of intelligent transportation systems involves the integration of electronic road tolls and how rail traffic can be re-scheduled when disturbances occur. The focus lies on transportation policy analysis, simulations, development of search algorithms and finding sustainable transportation solutions.

Distributed systems

In the distributed systems field architecture of multiprocessors and data in the cloud (a technology based on the use of computers over the Internet) are studied. Another area is the artificial intelligence and human-machine interaction. The focus is on various cloud services and applications in social networks.


In the security research field machine learning techniques and anomaly detection (finding patterns in data that do not conform to an established "normal" behavior) are used to analyze irregularities in large sets of data. The focus is to identify and correct weaknesses in the police- and defense fields, industrial applications and among end users.

Applied system sciences

Within informatics/Applied system science we research methods and tools for user-driven design of services. This may involve mobile services for mapping accessibility in a municipality, as is the case in the Augment project. The project’s objective is for the users themselves to be able to update the accessibility database with current information and collaborate on improving the accessibility. This can include games for balance training and rehabilitation, as in the project GAME + HEALTH = TRUE! User-driven design of services is becoming increasingly common in both e-health and e-government.
