1. 1. Gap properties of helical edge states in two-dimensional topological insulators with time-dependent magnetic impurities

   University essay from Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen

   Author : Simon Wozny; [2020]
   Keywords : topological insulators; edge states; impurities; density of states; Green s function; Floquet; Physics and Astronomy;

   Abstract : The quantum mechanical equivalent of the classical Hall effect can lead to interesting results in solid state physics. A similar effect, that has received attention in recent years, occurs when large spin-orbit coupling is present in a material, the so-called quantum-spin Hall effect. READ MORE

3. 2. Plasma density characteristics of magnetic holes near the Kronian magnetosphere boundary surfaces

   University essay from Uppsala universitet/Institutionen för fysik och astronomi

   Author : Marlon Luis Bause; [2020]
   Keywords : Magnetic holes; Saturn; Langmuir Probe; plasma electron density; Magnetosphere;

   Abstract : Localized structures of the magnetic field strength depression are often observed in the interplanetarymedium, and they are called ‘magnetic holes’ after the original work of Turner et al. 1977. A numberof observations of similar features have been reported, while the mechanisms of their origin have notfully understood yet. READ MORE

4. 3. Design of a Ski Mountaineering Helmet

   University essay from Luleå tekniska universitet/Institutionen för ekonomi, teknik och samhälle

   Author : Mikaela Zernell; [2020]
   Keywords : Design; Ski Mountaineering; Helmet; Design Process; industrial design;

   Abstract : This is a master thesis project in Industrial Design Engineering at Luleå University of Technology performed during the spring semester 2019 and with the goal to design a helmet for POC specialized for ski mountaineering.   To cope with new rules in ski mountaineering competitions, to widen the product catalogue of POC and to make ski mountaineering safer and more enjoyable, a double certified helmet was to be designed, meaning certified for both mountaineering and downhill skiing.

5. 4. Multipoint Measurements of Magnetic Holes in the Pristine Solar Wind

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Henrik Mejergren; [2020]
   Keywords : ;

   Abstract : Satellite data from the Cluster satellites have been used to find and evaluate structures in the pristine solar wind, referred to as magnetic holes. By using multipoint measurements, size and orientation-estimates are established. Other characteristics of interest are also examined, such as velocity, temperature, density, and pressure. READ MORE

6. 5. Modelling and interpretation of VTEM data from Soppero, Sweden

   University essay from Luleå tekniska universitet/Geovetenskap och miljöteknik

   Author : Linnéa Johansson; [2017]
   Keywords : Transient electromagnetic; geophysics; geophysical modelling; Soppero;

   Abstract : The geological and geophysical knowledge about the northernmost part of Sweden has recently increased due to the Barents project, which includes acquisition of modern geophysical and geological information on behalf of the Swedish Geological Survey (SGU). During August 2013, a helicopter-borne versatile time domain electromagnetic (VTEM) survey was performed by Geotech Ltd, in the Soppero area northeast of Kiruna. READ MORE
