1. 1. Ageing process analysis of solar panels in graveyard geostationaryorbit for reusability potential

   University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

   Author : Robin Drevet; [2024]
   Keywords : space debris; Spacecraft Materials; satellite; Space Sustainability; Space Circularity; Space Manufacturing;

   Abstract : The constant growth of space debris and the associated risks force the space community to find solutions to mitigate them. Today the most advanced solutions to dispose of satellites and rocket stages after the end of mission consists of moving them either into a graveyard orbit or towards an atmospheric re-entry ending in the demise of both spacecraft and its materials.

5. 4. Exploring the effects of pressure on the magnetic properties of quasi-low dimensional quantum magnets via thermodynamic measurements

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

   Author : Emelie Zhu; [2024]
   Keywords : Physics and Astronomy; Technology and Engineering;

   Abstract : Four model solid state compounds were used to experimentally investigate the effects of pressure on the interactions in one- and two-dimensional Heisenberg magnetic models. BaCuSi2O6, BaCu2V2O8, SrCuO2 and CuGeO3 were successfully synthesized via solid-state reactions and characterized via x-ray diffraction. READ MORE

6. 5. Detecting Fraudulent User Behaviour : A Study of User Behaviour and Machine Learning in Fraud Detection

   University essay from Uppsala universitet/Analys och partiella differentialekvationer

   Author : Patrik Gerdelius; Sjönneby Hugo; [2024]
   Keywords : Fraud Detection; User Behaviour; Random Forest; PCA; SMOTE;

   Abstract : This study aims to create a Machine Learning model and investigate its performance of detecting fraudulent user behaviour on an e-commerce platform. The user data was analysed to identify and extract critical features distinguishing regular users from fraudulent users. READ MORE
