Research directions
Sensor information systems
The main research objectives are sensor data acquisition, information processing and process control, sensor-information systems, and connection between distributed systems and microprocessor controllers. The research focus is on the relation between different communication interfaces/environments, especially the connection between wireless sensor networks and conventional systems/environments, and on the development of microprocessor distributed systems for information processing and control. The activity is directed to the design of network systems embracing research apparatus as end-devices with wireless communication between them; research on ZigBee technology implementation for control of swarms of mobile devices; extension of wireless sensor network applications — work on the SMART METERING direction, development of wireless sensor networks for home automation and consumption monitoring; and realization and integration of wireless abilities with industrial applications and process control.
Personalized technology enhanced learning (eLearning)
Approaches to learner modelling, adaptable and adaptive e-learning environments, instruments for development of educational materials, reuse of educational materials, collaboration of partners in the teaching–learning process, communication services for collaboration and reuse, learning technologies, and development of educational e-games. The research focus is on the development of personalized learning facilities for pupils with specific learning difficulties like dyslexia and autism.
Dependable, secure and resilient computer systems and networks
Modelling of fault-tolerant systems and networks; developing simulation models of real-time process control systems; studying the quality of service of communication networks. Recently the efforts have been directed towards research in the fields of information security and the development of the resilience concept: study of future and emerging information security threats, developing methods and models to decrease vulnerabilities in systems and networks, and improving network protection against attacks (e.g. in wireless sensor networks), implementation of security tools in control systems operating in open network environments. Researches continue on the development of the dependability and security model with new properties such as self-healing, adaptation to continuously changing circumstances, and self-learning for more efficient dealing with future challenges, i.e. use and implementation of the resilience approach.
Compression, processing, recognition and security of digital visual information
