  1. 1. Exploring adaptation of self-supervised representation learning to histopathology images for liver cancer detection

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

    Author : Markus Jonsson; [2024]
    Keywords : Self-supervised learning; Representation learning; Computer vision;

    Abstract : This thesis explores adapting self-supervised representation learning to visual domains beyond natural scenes, focusing on medical imaging. The research addresses the central question: "How can self-supervised representation learning be specifically adapted for detecting liver cancer in histopathology images?" The study utilizes the PAIP 2019 dataset for liver cancer segmentation and employs a self-supervised approach based on the VICReg method. READ MORE

  4. 3. The Speed of Clouds : Utilizing Adaptive Sampling to Optimize a Real-Time Volumetric Cloud Renderer

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Emrik Hydén; [2023]
    Keywords : Volumetric clouds; Ray marching; Bilinear interpolation; Adaptive sampling; Unity3D; Volymetriska moln; Ray marching; Bilinjär interpolering; Adaptiv sampling; Unity3D;

    Abstract : Volumetric clouds are often used in video games in order to improve the realism or graphical quality of the game. However, in order to achieve real-time rendered clouds, optimizations have to be implemented as part of the rendering algorithm. READ MORE

  5. 4. Into the Trading Book: Estimating Expected Shortfall

    University essay from Lunds universitet/Nationalekonomiska institutionen

    Author : Robin Eric Schmutz; Leonard Schneider; [2023]
    Keywords : Expected shortfall; Trading book; Historical simulation; Parametric estimation; Backtesting; Business and Economics;

    Abstract : In light of the revised 2019 proposals constituting the Fundamental Review of the Trading Book, which amend the third Basel Accord, expected shortfall is set to replace value at risk as the risk measure dictating banks' capital reserving requirements for exposure to market risk. This paper examines how best to accurately estimate expected shortfall from a regulatory perspective by carrying out an array of non-parametric as well as parametric methods over the recent years of financial instability.

  6. 5. Feasibility of quantitative 99mTc-DPD scintigraphy SPECT/CT for assessing the burden of ATTR cardiac amyloidosis

    University essay from Umeå universitet/Radiofysik

    Author : Sajad Kadhim Khalaf; [2023]
    Keywords : QSPECT; Amyloidosis; ATTR; LVMI; Recovery Coefficient; SUV; Calibration;

    Abstract : Background: Amyloid transthyretin (ATTR) cardiomyopathy is caused by the deposition of misfolded proteins, known as amyloid fibrils, in the myocardium. Quantitative Single Photon Emission Computed Tomography (QSPECT) utilizing 99mTc-DPD scintigraphy has the potential to assess ATTR-suspected cardiac amyloidosis (CA). READ MORE
