1. Off-State Stress Effects in AlGaN/GaN HEMTs : Investigation of high-voltage off-state stress impact on performance of and its retention in hybrid-drain ohmic gate AlGaN/GaN HEMTs
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : High electron mobility transistors (HEMTs) realized using AlxGa1-xN/GaN are relatively new technology which is prominent for high-speed and high-power applications. Some of the main problems with this technology were identified as dynamic RDSon, current collapse and threshold voltage instabilities due to the off-state stress. READ MORE

2. Calculating the combined elemental composition of spodumene using La_ICP_MS in thin_sections samples from Europe.
University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurserAbstract : The study gives a broad background to understand the high demand of lithium batteries in the coming years, especially in Europe. The goal of the study is to use La-ICP-MS to analyse spodumene samples from different lithium deposits in Europe to get a better knowledge of the contents of trace elements in spodumene. READ MORE

3. Analysis of relatedness and genetic diversity in Swedish sheep breeds using medium density (50K) SNP data
University essay from SLU/Dept. of Animal Breeding and GeneticsAbstract : The local Swedish sheep breeds belong to a group of sheep breeds known as North European short-tailed sheep breeds. Evaluation of genetic diversity, relatedness, and population structure of local breeds offers crucial metrics to prevent inbreeding depression, genetic erosion, and crossbreeding between locally adapted and exotic sheep breeds since these occurrences can have detrimental effects and ultimately lead to extinction.

4. Thresholds to the ancestors : An examination of south-west portals with regards to cult and symbolism
University essay from Uppsala universitet/ArkeologiAbstract : 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. READ MORE

5. Fitting a photospheric prompt emission model to GRB data: The Kompaneets RMS approximation (KRA)
University essay from KTH/FysikAbstract : Gamma-ray bursts (GRBs) are some of the most energetic events in the universe. Shocks occurring below the photosphere are likely radiation mediated shocks (RMSs) and are suspected to shape the spectra. Due to computational costs of simulating RMSs, models had not been fitted to data and a faster model was needed. READ MORE
