  1. 1. A Series of Stairs : And the production of meaning through architectural research, architectural typology and architectural representation

    University essay from Umeå universitet/Arkitekthögskolan vid Umeå universitet

    Author : Hilma Rundblad; [2023]
    Keywords : ;

    Abstract : 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. READ MORE

  3. 2. Multi-Scale Topology Optimization of Lattice Structures Using Machine Learning

    University essay from Uppsala universitet/Tillämpad mekanik

    Author : Julia Ibstedt; [2023]
    Keywords : Topology optimization; Multi-scale topology optimization; Machine learning; Gaussian process; Homogenization; Inverse homogenization; Anisotropic materials; Symmetry groups; Material property space; Topologioptimering; Flerskalig topologioptimering; Maskininlärning; Gaussian process; Homogenisering; Anisotropa material; Symmetrigrupper; Materialegenskapsrymd;

    Abstract : 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.

  4. 3. Approximating Quasistationary Distributions Using Deep Learning

    University essay from KTH/Matematisk statistik

    Author : Björn Wehlin; [2022]
    Keywords : Applied Mathematics; Deep Learning; Probability Theory; Stochastic Processes; Ito Diffusions; Quasistationary Distributions; Tillämpad matematik; djupinlärning; sannolikhetsteori; stokastiska processer; Ito-diffusioner; kvasistationära fördelningar;

    Abstract : 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). READ MORE

  5. 4. Medicalizing Me Softly: An Autoethnography of Refusal

    University essay from Lunds universitet/Graduate School

    Author : Han Amm; [2022]
    Keywords : transmedicalism; truscum; transnormativity; nonbinary; autoethnography; refusal; liminality; Social Sciences;

    Abstract : This autoethnographic study explores intra-community discursive boundary constructions around the category of transgender articulated by truscum trans men on Reddit. It does so through reflections on how the author negotiates the medical model of trans, his own gender identity, the medico-juridical interlock governing access to trans healthcare and trans livability, and tensions of closeness/distance to those they interview.

  6. 5. Approximating the element matrices in an unfitted finite element method using neural networks

    University essay from Umeå universitet/Institutionen för fysik

    Author : Amanda Bertgren; [2022]
    Keywords : Finite element method; CutFEM; neural networks; machine learning;

    Abstract : This study investigates the possibility of combining an unfitted finite element method, CutFEM, with neural networks, in an attempt to reduce the computational time on evolving domains. Finite element methods are used to solve partial differential equations by fitting a spatial and temporal discretisation to the momentous domain. READ MORE
