1. Investigating self-discharge in a graphite dual-ion cell using in-situ Raman spectroscopy.
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/StrukturkemiSammanfattning : Anion intercalation in the graphite positive electrode of a dual-ion battery requires high potential (> 4.3 V vs Li+/Li), which aggravates parasitic reactions involving electrolyte decomposition and Al corrosion, manifesting in poor coulombic efficiency, cycle life, and quick self-discharge.

2. Open-Circuit-Voltage hysteresis measurement and modelling of LiFePO4 Batteries : Master Thesis Report - 2023
Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)Sammanfattning : In a context of an expected increasing use of Lithium-ion batteries in the transportation sector, Volvo AB is developing its own solutions for large electric vehicles. It is then beneficial to reduce the costs, the energy demand and the raw materials demand by improving the battery systems’ performances. LÄS MER
3. Regularizing Vision-Transformers Using Gumbel-Softmax Distributions on Echocardiography Data
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : This thesis introduces an novel approach to model regularization in Vision Transformers (ViTs), a category of deep learning models. It employs stochastic embedded feature selection within the context of echocardiography video analysis, specifically focusing on the EchoNet-Dynamic dataset. LÄS MER
4. Evaluation of pretension losses in heated screw joint
Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematikSammanfattning : The heated flow within the silencers of heavy transport vehicles can easily reach temperatures of hundreds of degrees Celsius. The thermal loads can cause problems for certain components on a silencer. LÄS MER
5. Modelling of nanometric cutting in metals using MD simulations
Magister-uppsats, Lunds universitet/MekanikSammanfattning : This master thesis project has been done within the Mechanics department of Lunds Tekniska Högskola (LTH). It studies the nanometric cutting process of a single crystal copper workpiece by a cubic diamond tool using Molecular Dynamics (MD) simulations on the software LAMMPS. LÄS MER
