11. Thresholds to the ancestors : An examination of south-west portals with regards to cult and symbolism
Master-uppsats, Uppsala universitet/ArkeologiSammanfattning : This thesis examines the relevancy of south-west portals with regards to their potential usage in post-burial ritual activity with particular focus on the deposition of sacrificial offerings. South-west portals are a type of stone constructions found on the edges of mounds and stone settings in eastern central Sweden usually dating to the Viking Age (c. LÄS MER
12. Influence of pulsing on PVD TiAlN coating microstructure and mechanical properties : Master thesis project on the impact of deposition parameters on performance and properties of PVD titanium aluminum nitride.
Master-uppsats, Karlstads universitetSammanfattning : This thesis investigates the influence of pulsing on the mechanical properties of PVD TiAlN coatings. The thesis focuses on defects caused by droplets during the arc-evaporation technique by altering the duty time, which affects mechanical properties. LÄS MER
13. Effects of Ultrafast Ionization in X-ray Coherent Diffraction Imaging
Master-uppsats, KTH/KemiSammanfattning : Koherent Diffraktionsavbildning med en intensiv röntgenpuls från en Frielektronlaser har möjliggjort strukturbestämning av isolerade nanopartiklar som inte går att studera med hjälp av konventionella metoder, så som elektronmikroskopi. En mycket kort pulslängd tillsammans med spridningssignalens beroende av objektets elektroniska struktur medför också möjligheten att studera inducerad ultrasnabb dynamik med denna teknik. LÄS MER
14. Modeling of the trajectory of ice thrown from a wind turbine
Master-uppsats, Lunds universitet/Institutionen för energivetenskaperSammanfattning : There is a growing number of wind turbines installed in cold temperature zones as a result of the restricted space for new construction. Due to ice deposition on the turbine blades, the increasing installation of wind turbines in freezing temperature areas presents many challenges: ice accumulation increases weight, unbalances the rotor, diminishes aerodynamic efficiency, and creates safety issues.

15. Computational investigation of the feasibility touse solid neon moderation for GBAR
Master-uppsats, Stockholms universitet/FysikumSammanfattning : The main goal of the GBAR (Graviational Behaviour of Antihydrogen at Rest) experiment is to investigatethe gravitational effect on antimatter by measuring the classical free fall of an antihydrogen atom. The requiredpositrons are created by pair production inside a tungsten target and are moderated using a tungsten mesh. LÄS MER
