1. Simplified Model For Simulation of Fault Ride Through at Hydropower Units
Master-uppsats, Uppsala universitet/Institutionen för fysik och astronomiSammanfattning : As new requirements for grid connected generators were implemented, the requirements for evaluating the Fault Ride Through capabilities of the generators became stricter. When refurbishing a power unit, proof that the power unit meet the requirements must be submitted to the authorities. LÄS MER
2. The role of location of low inertia in power systems
Master-uppsats, Uppsala universitet/Institutionen för elektroteknikSammanfattning : The plans to reduce the energy-related greenhouse gas emissions stimulate the deployment of electronically interfaced renewable resources. The increased penetration of such intermittent sources together with phasing conventional power plants out and the installation of High Voltage Direct Current (HVDC) links for long-distance more efficient transmission, reduces the stored inertia in any electrical grid.

3. Preventing Inertia: Levaraging the Usage of Facebook as a Dynamic Capability
Kandidat-uppsats, Högskolan i Jönköping/Internationella HandelshögskolanSammanfattning : Background – Inertia describes a state whereby companies develop slower relative the pace of change experienced by their environment, something most organizations experience at least once in their lifetime. Being in the state of inertia and consequently failing to adapt to change cause new businesses to replace old ones. LÄS MER
4. Corporate Bond Yield Spreads: A Search-based Sentiment Approach
C-uppsats, Handelshögskolan i Stockholm/Institutionen för finansiell ekonomiSammanfattning : This study examines the effect of investor sentiment, as measured by internet search activity, on corporate bond yield spreads. Specifically, we predict systematic reversal patterns as a result of sentiment-induced mispricing: In pessimistic regimes bonds appear underpriced with higher yields than indicated by fundamental values.

5. Rheological changes at the air-liquid interface and examining different kind of magnetic needles
Master-uppsats, Karlstads universitet/Avdelningen för kemiteknikSammanfattning : The main objective in this work was to learn how the instrument, the Interfacial Shear Rheometer (ISR400), worked and to investigate how the rheological properties, storage modulus (elasticity), G' and loss modulus (viscous), G'', changes when the surface pressure at the air-liquid interphase changes. The second objective were to examine the different kind of magnetic needles used in the experiments and to conclude which type of needle is best for its specific field of analysis. LÄS MER
