11. Dam Failure Analysis of the Parteboda Hydropower Plant : A deterministic approach
University essay from KTH/Hållbar utveckling, miljövetenskap och teknikAbstract : Despite all the benefits a dam can provide, hundreds of years of experience have shown the destructive forces that can be unleashed by dam failure. To carry out risk management and execute mitigative measures for a dam facility, it is first necessary to assess the incremental consequences of a potential dam failure. READ MORE

12. Scattering of Charge Carriers in 2+1-Dimensional Quantum Field Theory
University essay from Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)Abstract : The aim of this thesis is to examine the hard $S$-matrix for QED and QCD, due to Hannesdottir and Schwartz [1], both recreating known results, and finding new results in lower dimensions. Electrons by themselves are not gauge invariant, and in the massless limit do not give finite $S$-matrix elements for individual processes; one needs to add together seemingly arbitrary combinations of diagrams in order to be able to calculate the scattering cross-section.

13. Improving the understanding of photoelectron currents on Solar Orbiter : Utilizing theory and empirical measurements
University essay from Uppsala universitet/Institutet för rymdfysik, UppsalaavdelningenAbstract : Spacecraft experience electric currents on conductive materials exposed to sunlight, which introduces noise in scientific data. These currents are mainly due to the photoelectric effect and should therefore be proportional to the inverse square heliocentric distance. READ MORE

14. How Does the Three-factor Model Perform and What Explains its Performance? Empirical tests on Swedish stock portfolios
University essay from Lunds universitet/Nationalekonomiska institutionen; Lunds universitet/Statistiska institutionenAbstract : In this study the three-factor model of Fama and French (1992; 1993) is evaluated on portfolios of Swedish stocks. Both a cross-section and time series approach are used to evaluate the model. The results show that beta, size, and book-to-market are significant variables in explaining excess returns of Swedish stock portfolios. READ MORE

15. Single- or Three-Phase Supply to Homes : Advantages and Disadvantages compared between Single-phase and Three-phase domestic electricity
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : A three-phase power supply is a de facto standard when selecting a power supply to homes in Sweden, regardless of whether it is flat with low energy consumption or a house with electric heating. This project aims to determine the advantages and disadvantages of using a three-phase supply compared to a single-phase supply to homes. READ MORE
