1. A theoretical framework for interpretation and prediction of magneto-optical measurements
Kandidat-uppsats, Uppsala universitet/MaterialteoriSammanfattning : The interplay of experiments and theory is essential to deepen our understanding of magnetization dynamics. This thesis aims to serve as a bridge between these two aspects by establishing a mathematical framework that enables the computation of optical observable quantities based on theoretical models.

2. Reducing Power Losses by Optimizing Cooling in Final Annealing of Non-Oriented Electrical Steel
Master-uppsats, KTH/MaterialvetenskapSammanfattning : Surahammars Bruks AB produces non-oriented electrical steel used in several types of motors and generators. Because of recent years exponentially growing market for electrical vehicles, non-oriented electrical steel used in electrical vehicle motors is becoming an increasingly important product. LÄS MER
3. Definition and evaluation of a system for measuring local geomagnetic variations : Autonomous station for magnetic measurements
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : Earth is under constant influence of the Sun and phenomena driven by the solar wind that may affect man-made technology. These events are summarized under the concept of space weather. This creates variations in Earth’s magnetic field and nearby space. Space weather can affect power grids, gas pipelines and also have effects on human health. LÄS MER
4. Strömfördelning i parallella kabelförband med fokus på förläggning
M1-uppsats, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)Sammanfattning : Med behovet på allt större transformatorer på hög- och mellanspänningsnivå krävs i mångafall flera parallella kablar på nedsida transformator, ibland ända upp till 6 parallella förband. Detta ställer särskilda krav på förläggning av förbanden för att undvika ojämn strömfördelning i ledarna. LÄS MER
5. Differences between solar atlases and implications on the solar oxygen abundance
Kandidat-uppsats, Uppsala universitet/Institutionen för fysik och astronomiSammanfattning : The determination of the solar oxygen abundance is a topic that has long beenunder debate, where the exact value has varied between researchers. These variationsin the oxygen abundance have implications on our understanding of the Sun and itsinterior as well as our understanding of other stars. LÄS MER
