1. 16. Colliding Galaxies in a (Nut)Shell

   University essay from Lunds universitet/Astronomi - Genomgår omorganisation; Lunds universitet/Fysiska institutionen

   Author : Jonathan Petersson; [2022]
   Keywords : shell galaxies; simulations; starbursts; quenching; mergers; Physics and Astronomy;

   Abstract : Galaxy interactions and mergers are natural recurring events in the current cosmological paradigm, events that often coincide with starbursts and enhanced star formation activity. To understand why that is, one can use idealised (non-cosmological) merger simulations, which provide freedom to recreate specific tidally distorted galaxies, and analysis of the time evolution and underlying physics of the star formation activity at a high spatial resolution.

3. 17. Imbalanced Predictions

   University essay from Lunds universitet/Statistiska institutionen

   Author : Stella Säfström; [2022]
   Keywords : Imbalanced data; cost-sensitive learning; SMOTE; random undersampling; Mathematics and Statistics;

   Abstract : The aim of the thesis is to evaluate solutions to the class imbalance problem using real world data sets with varying degrees of class imbalance. The analysis is limited to binary classification. Three large data sets relating to credit card fraud, vehicle insurance and heart disease are used for the analysis. READ MORE

4. 18. Why might the published data on sexual assault against children not be reflecting the reality of lived experiences? : On the example of a community in Western Kenya.

   University essay from Karlstads universitet/Centrum för genusforskning (from 2013)

   Author : Marta Murawska; [2022]
   Keywords : Western Kenya; decolonial feminism; gender-based violence; sexual education; child abuse.;

   Abstract : In my essay, I have considered whether the data in publications on sexual violence against children reflectreality. I suspect that there are cases of child sexual abuse that goes underreported, and I try to investigate why this happens and the key possible reasons that lower the statistics. READ MORE

5. 19. Evaluation of Convolutional Neural Networks for Image Quality Classification based on Synthetic Data

   University essay from Lunds universitet/Matematik LTH

   Author : Vendela Nigård; Joar Karlgren Gustavsson; [2022]
   Keywords : Convolutional neural networks; Machine learning; transfer learning; image quality assessment; camera production; image analysis; Mathematics and Statistics;

   Abstract : In camera production the image quality is of utter importance. Several tests during the production ensure this high quality. In this thesis the possibility of creating a final test, that classifies the image quality with the help of machine learning, specifically convolutional neural networks, was investigated. READ MORE

6. 20. An Extreme Value Approach to Modelling Construction Defect Insurance Claims

   University essay from Lunds universitet/Matematisk statistik

   Author : Matilda Ekermann; Ida Swartling; [2022]
   Keywords : Extreme value theory; insurance; block-maxima; peaks over threshold; Poisson process; Mathematics and Statistics;

   Abstract : Predicting future large claims, as well as the total cost, of a specific insurance is essential for insurance companies, for example when setting premium levels or purchasing reinsurance coverage. The purpose of this thesis is to investigate if extreme value theory can be applied to construction defect insurance claims. READ MORE
