  1. 1. X-Ray Tomography on Intestine Samples

    University essay from Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

    Author : Julia Rogalinski; [2023]
    Keywords : Physics and Astronomy;

    Abstract : Enteric neuropathy describes a disease of the bowel caused by anomalies in the enteric nervous system. Patients suffering from this disease have symptoms including nausea, vomiting, diarrhea and pain. As enteric neuropathy is not well understood yet, its diagnosis is a non-trivial task. READ MORE

  3. 2. Classification and localization of extreme outliers in computer vision tasks in surveillance scenarios

    University essay from KTH/Hälsoinformatik och logistik

    Author : Tariq Daoud; Emanuel Zere Goitom; [2022]
    Keywords : Computer vision; deep learning; machine learning; artificial neural networks; convolutional neural networks; YOLOv4; Datorseende; djupinlärning; maskininlärning; artificiella neurala nätverk; konvolutionella neurala nätverk; YOLOv4;

    Abstract : Convolutional neural networks (CNN) have come a long way and can be trained toclassify many of the objects around us. Despite this, researchers do not fullyunderstand how CNN models learn features (edges, shapes, contours, etc.) fromdata. READ MORE

  4. 3. Snow cover related camouflage mismatch decreases survival

    University essay from SLU/Dept. of Wildlife, Fish and Environmental Studies

    Author : Pieter Otte; [2022]
    Keywords : climate change; snow cover; seasonal colour coat; crypsis; mismatch; camera trap; survival analysis;

    Abstract : Climate change is expected to decrease winter severity at high latitudes, resulting in reduced days of snow cover. Several mammalian and avian species in the northern hemisphere express a seasonal colour coat (SCC) making them white in winter periods and brown or dark in summer. READ MORE

  5. 4. Heterogeneous catalytic reactions studied with transient gas supply and event-averaged ambient pressure x-ray photoelectron spectroscopy

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/NanoLund: Centre for Nanoscience

    Author : Qianhui Liu; [2022]
    Keywords : Ambient pressure x-ray photoelectron spectroscopy; Event-averaging; Pd 100 surface structure oscillation; Physics and Astronomy;

    Abstract : CO oxidation over Pd(100) is studied with ambient pressure x-ray photoelectron spectroscopy (APXPS). Cyclic gas composition pulsing of the CO:O2 ratio, combined with a new method using software based event-averaging by image recognition over many pulses, is used to improve the signal-to-noise ratio substantially.
