1. A Series of Stairs : And the production of meaning through architectural research, architectural typology and architectural representation
Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Arkitekthögskolan vid Umeå universitetSammanfattning : Liminal spaces are broadly overlooked within spatial research but are no less significant as spaces in which emotions, identity and meaning might be embedded. Residential staircases are no exception. LÄS MER
2. Multi-Scale Topology Optimization of Lattice Structures Using Machine Learning
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Tillämpad mekanikSammanfattning : This thesis explores using multi-scale topology optimization (TO) by utilizing inverse homogenization to automate the adjustment of each unit-cell's geometry and placement in a lattice structure within a pressure vessel (the design domain) to achieve desired structural properties. The aim is to find the optimal material distribution within the design domain as well as desired material properties at each discretized element and use machine learning (ML) to map microstructures with corresponding prescribed effective properties.

3. Dynamisk analys av betonghåldäck : Parametrisk FEM studie
Kandidat-uppsats, KTH/Byggteknik och designSammanfattning : Hollow-core concrete slabs can be used in buildings to achieve longer floor spans in comparison to regular concrete slabs. However, longer floor spans in combination with low dead-weight make them more susceptible to vibrations.Frequencies between 0-15 Hz are relevant to study since these lower frequencies affect the comfort of humans.

4. An Application of LatentCF++ on Providing Counterfactual Explanations for Fraud Detection
Master-uppsats, Stockholms universitet/Institutionen för data- och systemvetenskapSammanfattning : The aim of explainable machine learning is to aid humans in understanding how exactly complex machine learning models work. Machine learning models have offered great performance in various areas. However, the mechanisms behind how the model works and how decisions are being made remain unknown. LÄS MER
5. Approximating Quasistationary Distributions Using Deep Learning
Master-uppsats, KTH/Matematisk statistikSammanfattning : We study a class of It\={o} diffusion processes on domains with smooth boundary, at which the process is killed. Such a process, when conditioned on non-extinction, gives rise to a stationary state known as a \emph{quasistationary distribution} (QSD). LÄS MER
