  1. 1. Improving echocardiogram view classification using diffusion models

    University essay from Göteborgs universitet/Institutionen för data- och informationsteknik

    Author : Luis Arevalo; Anouka Ranby; [2023-10-23]
    Keywords : Computer; science; computer science; engineering; project; artificial intelligence; machine learning; deep neural networks; diffusion models; synthetic data; echocardiogram classification;

    Abstract : In the field of medical science datasets are often highly imbalanced, where rare datapoints are of high importance. This study aims to explore the usage of synthetic datasets to improve the classification of echocardiogram views. READ MORE

  3. 2. How About Running on Mars ? Influence of Sensory Coherence on the Running Pattern and on Spatial Perception in Simulated Reduced Gravity

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Marie Keime; [2022]
    Keywords : Adaptation; Gravity; Locomotion; Sensory factors; Spatial perception; Unweighting.; Rörelse; Gravitation; Anpassning; Avvägning; Sensoriska faktorer; Rumslig uppfattning.;

    Abstract : Motor control, including locomotion, strongly depends on the gravitational field. Recent developments like lower-body positive pressure treadmills (LBPPTs) have enabled Earth- based studies on the effects of reduced body weight (BW) on walking and running. Yet, the observed adaptations to simulated hypogravity are not optimal. READ MORE

  4. 3. Automatic Left Ventricle Segmentation of Long-Axis Cardiac MRI-Images

    University essay from Lunds universitet/Matematik LTH

    Author : Ruben Bergengrip; [2021]
    Keywords : MRI; Magnetic resonance imaging; Deep Learning; Machine learning; U-net; CNN; Semantic segmentation; Segmentation; Global longitudinal strain; GLS; strain; AV-plane displacement; AVPD; long-axis; left ventricle; LV; cardiac MRI; CMR; Image analysis; Technology and Engineering;

    Abstract : Over 30 % of all deaths worldwide are related to cardiovascular diseases and they are the leading cause of death. Therefore, research into treatment, diagnosis and prognostication of these diseases are of critical importance. One way to examine the cardiovascular system is through the use of Magnetic Resonance Imaging (MRI). READ MORE

  5. 4. Internal geology and emplacement processes of Kimberlites, Case Study from the Tsabong Kimberlite Field, Botswana

    University essay from Luleå tekniska universitet/Geovetenskap och miljöteknik

    Author : Mpho Ndebele; [2020]
    Keywords : Kimberlites; Geology; Emplacement Processes; Botswana;

    Abstract : The Crateceous (85 Ma) MK1 pipe is part of the Tsabong kimberlite cluster located approximately550km south west of Gaborone and geologically found within the Kapvaal Craton. The Tsabongkimberlite field consists of 86 known kimberlites. The MK1 pipe is the largest of this cluster at 140ha,1. READ MORE

  6. 5. Principal Component Analyses of Final States in Relativistic Nuclear Collisions using PYTHIA/Angantyr

    University essay from Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

    Author : Nicoline Krogh Hemme; [2020]
    Keywords : Relativistic Nuclear Collisions; Heavy-ion Collisions; Pythia; Angantyr; String Shoving; Colour Reconnection; Principal Component Analysis; Anisotropic Flow; Elliptic Flow; Event-by-event Fluctuations; Physics and Astronomy;

    Abstract : We develop a program to perform a principal component analysis of flow fluctuations using simulations of nuclear collisions produced by the PYTHIA/Angantyr event generator. We consider both p+p and p+Pb collision events and study the leading and subleading modes of the second flow harmonic. READ MORE
