11. Buoy for linear wave energy converter
Sammanfattning : A wave energy converter (WEC) of point absorber type has been developed and tests have been conducted outside Lysekil. The project started in 2002 and linear permanent magnet generators together with a subsea substation and buoys of various geometric shapes have been built and tested. LÄS MER
12. Contributions to Confidentiality and Integrity Algorithms for 5G
Sammanfattning : The confidentiality and integrity algorithms in cellular networks protect the transmission of user and signaling data over the air between users and the network, e.g., the base stations. LÄS MER
13. Dynamic threshold generators for robust fault detection
Sammanfattning : Detection of faults, such as clogged valves, broken bearings or biased sensors, has been brought more and more into focus during the last few decades. There are two main reasons why faults are important to detect at an early stage. LÄS MER
14. Numerical Modelling and Mechanical Studies on a Point Absorber Type Wave Energy Converter
Sammanfattning : Oceans cover two thirds of the Earth’s surface and the energy potential of ocean waves as a renewable energy source is huge. It would therefore be a tremendous achievement if the vast mechanical energy in waves was converted into a form of energy that could be used successfully by society. LÄS MER
15. Around minimal Hilbert series problems for graded algebras
Sammanfattning : The Hilbert series of a graded algebra is an invariant that encodes the dimension of the algebra's graded compontents. It can be seen as a tool for measuring the size of a graded algebra. This gives rise to the idea of algebras with a "minimal Hilbert series", among the algebras within a certain family. LÄS MER
