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

3. 2. A Machine Learning Approach on Analysis of Emission Spectra for Application in XFEL Experiments

   University essay from Uppsala universitet/Institutionen för fysik och astronomi

   Author : Harald Agelii; [2023]
   Keywords : Structural biology; Machine learning; Neural networks; emission spectrum; XFEL; X-ray free electron laser; SFX; Serial femtosecond X-ray crystallography; Proteins; Diagnostics;

   Abstract : In this thesis we investigate two potential applications of machine learning in the context of X-ray imaging and spectroscopy of biological samples, particularly such using X-ray free electron lasers (XFEL). We first investigate the possibility of using an emission spectrum, recorded from a sample after being probed by an incident X-ray, as a diagnostic tool. READ MORE

4. 3. Investigation of Registration Methods for High Resolution SAR-EO Imagery

   University essay from Linköpings universitet/Datorseende

   Author : Niclas Hansson; [2022]
   Keywords : SAR; FFT; MI; Image Registration;

   Abstract : With advancements in space technology, remote sensing applications, and computer vision, significant improvements in the data describing our planet are seen today. Researchers want to gather different kinds of data and perform data fusion techniques between them to increase our understanding of the world. READ MORE

5. 4. Simulated cerebrospinal fluid motion due to pulsatile arterial flow : Master Thesis Project

   University essay from Umeå universitet/Institutionen för fysik

   Author : Jesper Hägglund; [2021]
   Keywords : Computational fluid dynamics; Fluid structure interaction; Pulsatile flow;

   Abstract : All organs, including the brain, need a pathway to remove neurotoxic extracellular proteins. In the brain this is called the glymphatic system. The glymphatic system works by exchanging proteins from interstitial fluids to cerebrospinal fluids. The extracellular proteins are then removed through the cerebrospinal fluid drains. READ MORE

6. 5. Thermographic Measurements of Hot Materials Using a Low- to High-speed RGB-camera : Prospect of RGB-cameras Within the Field of Thermographic Measurements

   University essay from Luleå tekniska universitet/Rymdteknik

   Author : Therese Berndtsson; [2019]
   Keywords : RGB-camera; thermographic measurements; calibration; temperature transform; thermal behavior; dual-wavelenght;

   Abstract : Monitoring the thermal behavior of material while heated or cooled is of great importance in order to understand the structural behavior of materials. This thesis aims to investigate the prospects for imaging hot materials using an RGB-camera. READ MORE
