1. 1. Forming wide-orbit planets via pebble accretion

   University essay from Lunds universitet/Astrofysik; Lunds universitet/Fysiska institutionen

   Author : Nerea Gurrutxaga; [2023]
   Keywords : Planet Formation; Pebble Accretion; Protoplanetary Disk; Wide-Orbit Planet; Physics and Astronomy;

   Abstract : The possibility that detected substructures in protoplanetary disks, such as gaps, rings and cavities, are created by distant protoplanets has prompted an inquiry into the mechanism responsible for their formation. These wide-orbit young bodies are likely to form relatively rapidly in the outer regions of circumstellar disks. READ MORE

3. 2. Structural Dynamics at Higher Frequencies using the Finite Element Method : Assessment of Solver Algorithms and Component Mode Synthesis for Dynamic Response Analysis of Large Structures

   University essay from KTH/Hållfasthetslära

   Author : Khashaiar Noushin; [2022]
   Keywords : ;

   Abstract : Scania is making a transition from traditional combustion engines to electric vehicles and therefore developing methodology for high frequency analysis of large structures. The computational time size of results files are impractically high, making any analysis infeasible. READ MORE

4. 3. Modelling of Social Networks, Analysis of CommunityStructures and Disease Simulation on Dairy Cattle : The aim of this study is to model a social network of dairy cows, detectcommunities and analyse the influence of these substructures on the spread of acontagious disease. By using this network, the transmission of a contagiousdisease will be simulated through a theoretical simulation function.

   University essay from Högskolan Dalarna/Institutionen för information och teknik

   Author : Juliana Macedo; Mira Czarnetzki; [2022]
   Keywords : Community Detection Dairy cattle Disease simulation Social Network;

   Abstract : Past research has demonstrated that social networks and community structures have a strong effecton the dynamics of how an infectious disease spreads, although many have focused moreintensively on the impact of the number of connections an individual has. This thesis investigatedhow disease transmission is affected by the social networks’ structures such as communities,centrality measures, cliques, and diameter. READ MORE

5. 4. Archaeologic inspection of the Milky Way using vibrations of a fossil : Seismic, spectroscopic and kinematic characterization of a binary metal-poor Halo star

   University essay from Uppsala universitet/Observationell astrofysik

   Author : Amanda Byström; [2020]
   Keywords : Milky Way; Halo; galactic archaeology; asteroseismology; binary star; CEMP stars; CEMP-r s stars; stellar age; stellar mass; chemical abundance pattern; Gaia-Enceladus; Gaia-Sausage; Sequoia; spectroscopy; metal-poor;

   Abstract : The Milky Way has undergone several mergers with other galaxies during its lifetime. The mergers have been identified via stellar debris in the Halo of the Milky Way. The practice of mapping these mergers is called galactic archaeology. To perform this archaeologic inspection, three stellar features must be mapped: chemistry, kinematics and age. READ MORE

6. 5. Lightcurves of super-Chandrasekhar mass supernovae

   University essay from Uppsala universitet/Institutionen för fysik och astronomi

   Author : Amanda Byström; [2020]
   Keywords : Type Ia supernovae; lightcurves; Chandrasekhar limit; SN2003fg; Phillip s relationship;

   Abstract : 20 supernovae that spectroscopically match the peculiar, superluminous type Ia supernova 2003fg are studied in this project. SN2003fg is thought to have erupted at a super-Chandrasekhar mass, thus breaching the theoretical mass limit for a white dwarf. READ MORE
