21. Automating Power Quality Analysis
Abstract : The increased requirements on supervision, control, and performance in modern power systems make power quality monitoring a common practise for utilities. Large databases are created and automatic processing of the data is required for fast and effective use of the available information. READ MORE

22. On Power-system Benefits, Main-circuit Design, and Control of StatComs with Energy Storage
Abstract : Static synchronous compensation (StatCom) is an application that utilizes a voltage source converter (VSC) to provide instantaneous reactive power support to the connected power system. Conventionally, StatComs are employed for reactive power support only. READ MORE

23. Effects of impurities on charge transport in graphene field-effect transistors
Abstract : In order to push the upper frequency limit of high speed electronics further, thereby extending the range of applications, new device technologies and materials are continuously investigated. The 2D material graphene, with its intrinsically extremely high room temperature charge carrier velocity, is regarded as a promising candidate to push the frequency limit even further. READ MORE

24. Materials for Magnetic Recording Applications
Abstract : In the first part of this work, the influence of hydrogen on the structural and magnetic properties of Fe/V(001) superlattices was studied. The local structure of the vanadium-hydride layers was determined by extended x-ray absorption fine structure (EXAFS) measurements. READ MORE

25. Influence of Composition and Pore Geometry on Immiscible Fluid Flow through Greensands: Development of Neutron Transmission Methods and Image Analysis
Abstract : The effect of the mineralogical composition and pore geometry of sediments on the distribution as well as the flow of immiscible fluids are of importance when evaluating petroleum reservoirs. Greensand containing the clay mineral glauconite is a complex reservoir rock type. READ MORE
