1. Experimental Results of a Load-Controlled Vertical Axis Marine Current Energy Converter
Sammanfattning : This thesis investigates the load control of a marine current energy converter using a vertical axis turbine mounted on a permanent magnet synchronous generator. The purpose of this thesis is to show the work done in the so far relatively uncharted territory of control systems for hydro kinetic energy conversion. LÄS MER
2. Studies of a Vertical Axis Turbine for Marine Current Energy Conversion : Electrical system and turbine performance
Sammanfattning : Ocean energy is a field of growing interest when it comes to renewable energy thanks to its high density of energy per unit area, and to the high predictability. Conversion of hydrokinetic energy, found in marine currents, is the utilization of the energy in free-flowing water for conversion to electric energy. LÄS MER
3. Grupparbetsbedömning på individnivå : Gymnasielärares möjligheter och utmaningar
Sammanfattning : Avhandlingens syfte är att öka kunskapen om och förståelsen av gymnasielärares möjligheter och utmaningar med att genomföra grupparbetsbedömning på individnivå av elevers kunskaper och förmågor utvecklade i samarbete. Fokus är på om och i så fall hur lärares perspektiv förändras i samband med genomförandet av en grupparbetsuppgift i klassrummet som inkluderar lärares grupparbetsbedömning på individnivå. LÄS MER
4. Childhood Obesity and Islet Function
Sammanfattning : The prevalence of childhood obesity and Type 2 Diabetes Mellitus (T2DM) has increased during recent decades. T2DM is accompanied with functional changes in the islets of Langerhans, which can be identified early in the pathogenesis. LÄS MER
5. Control strategies for various grid conditions in wave energy system
Sammanfattning : The imperative goal of reducing carbon emissions and reaching net zero emissions in electricity generation has driven various renewable technologies, including wind energy, solar energy, and wave energy, among others. Even though wave energy is a recent addition to the already existing renewable energy technologies, it offers distinct advantages, such as a high power density and lower inter-annual variability compared to wind energy.
