  1. 11. Wave power - The future of energy supply? Focusing on its sealing solutions

    University essay from KTH/Maskinkonstruktion (Inst.)

    Author : Christian Kälvegren; Tobias Sjölin; [2017]
    Keywords : Gaiter; sealing concepts; wave power; Damask; tätningskoncept; vågkraft;

    Abstract : A new concept for extracting renewable power has been developed at KTH Electric Power and Energy Systems, this time regarding wave power. Unlike other wave energy converters this concepts generator opens up the possibility to be operative also during low speed and at the same time preserve high power density and efficiency. READ MORE

  2. 12. Simulation of industrial control system field devices for cyber security

    University essay from KTH/Elkraftteknik

    Author : Dorothea Andersson; [2017]
    Keywords : ICS field device simulation. Test beds. CRATE. Honeyd. Nmap. Wireshark. QTester104. IEC 60870-5-104;

    Abstract : Industrial Control Systems (ICS) are an integral part of modernsociety, not least when it comes to controlling and protecting criticalinfrastructure such as power grids and water supply. There is a need to testthese systems for vulnerabilities, but it is often difficult if not impossible to doso in operational real time systems since they have been shown to be sensitiveeven to disturbances caused by benign diagnostic tools.
