  1. 1. The value of cardiac MRI texture analysis in patients with clinically suspected myocarditis

    University essay from

    Author : Evin Ina Papalini; [2021-05-10]
    Keywords : Medical physics; Myocarditis; Cardiac magnetic resonance; Texture analysis;

    Abstract : Purpose: The aim of this proof-of-concept study was to assess the diagnostic value of texture analysis (TA) based on conventional balanced steady-state-free precession (bSSFP), late gadolinium enhancement (LGE) and T2-weighted cardiac magnetic resonance imaging (CMRI) in patients with clinically suspected myocarditis. Method: A retrospective cohort study was performed based on 30 patients who underwent a comprehensive CMRI due to clinically suspected myocarditis between 2013 and 2018 at the Sahlgrenska University Hospital: 10 patients with clinical signs and positive myocardial biomarkers (Troponin T, indicating myocardial injury) as well as positive CMRI findings according to Lake Louise Criteria (LLC; group 1), 10 patients with clinical signs and positive myocardial biomarkers but negative CMRI findings according to LLC (group 2), and 10 patients with clinical signs but both negative myocardial biomarkers as well as CMRI findings according to LLC (control group).

  2. 2. Using Machine Learning for Predictive Maintenance in Modern Ground-Based Radar Systems

    University essay from KTH/Matematisk statistik

    Author : Dina Faraj; [2021]
    Keywords : Predictive Maintenance; Machine learning; Isolation forest; K-means clustering; Logistic regression; Radar systems.; Prediktivt underhåll; Maskininlärning; Isolation forest; K-means klustring; Logistisk regression; Radarsystem.;

    Abstract : Military systems are often part of critical operations where unplanned downtime should be avoided at all costs. Using modern machine learning algorithms it could be possible to predict when, where, and at what time a fault is likely to occur which enables time for ordering replacement parts and scheduling maintenance.

  3. 3. Modeling wind-induced currents in lake Bolmen, Sweden, using TELEMAC 2D

    University essay from Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Author : Prasanjaya Bandara Ekanayake; [2021]
    Keywords : Bolmen Lake; TELEMAC 2D; Wind induced currents; QGIS; Blue Kenue; Technology and Engineering;

    Abstract : Transport and material intermixing within lake systems have a significant impact on lake water quality. However, since researchers are primarily concerned with biological, environmental, and ecological aspects, physics and hydrodynamic behavior in lake water currents frequently receive less attention.

  4. 4. Optical characterisation of AAO/CsPbBr3 perovskite nanocomposites

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

    Author : Klára Nováková; [2021]
    Keywords : perovskite; scintillator; optoelectronics; semiconductor; X-ray detection; Physics and Astronomy;

    Abstract : Direct bandgap metal lead halide perovskites offer promising optoelectronic properties desirable in a wide range of applications including photodetection. However, the incomplete and poor understanding of the photophysical processes taking place in these materials, along with their poor stability, is the bottleneck for optimisation and further development of metal halide perovskite devices.

  5. 5. Steering Control During μ-split Braking for an Autonomous Heavy Road Vehicle

    University essay from Linköpings universitet/Fordonssystem

    Author : Sebastian Haglund; Henrik Johansson; [2020]
    Keywords : steering; braking; autonomous; μ-split; split-μ; truck; vehicle; control;

    Abstract : A critical maneuver for a heavy vehicle is braking with different friction on the left and right hand side of the vehicle, called μ-split. This results in an unwanted yaw torque acting on the vehicle. During this situation, the driver maintains the lateral stability and follows the desired path by corrective steering. READ MORE
