  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).

  3. 2. Prioritising biochar application to arable land in Sweden : A spatial multi-criteria analysis

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Fabian Osslund; [2020]
    Keywords : Biochar; Spatial multi-criteria analysis; GIS; Agriculture; Soil enhancement; Biochar volume potential;

    Abstract : Biochar, the solid product of thermal conversion of biomass with little or no available air, is acknowledged as a carbon dioxide removal technique and soil enhancer among other applications. Its potential soil enhancing properties consists of increased water and nutrient holding capacities, liming effects and sorption of pollutants. READ MORE

  4. 3. Texture Enhancement in 3D Maps using Generative Adversarial Networks

    University essay from Linköpings universitet/Datorseende

    Author : Anna Birgersson; Klara Hellgren; [2019]
    Keywords : GAN; texture enhancement; SRGAN; pix2pix;

    Abstract : In this thesis we investigate the use of GANs for texture enhancement. To achievethis, we have studied if synthetic satellite images generated by GANs will improvethe texture in satellite-based 3D maps. We investigate two GANs; SRGAN and pix2pix. READ MORE

  5. 4. Evaluation of biometric security systems against artificial fingers

    University essay from Institutionen för systemteknik

    Author : Johan Blommé; [2003]
    Keywords : Informationsteknik; biometric; artificial fingers; fingerprint scanners; minutiae; pattern matching; intrusion methods; normalization; binarization; direction field analysis; thinning algorithms; Informationsteknik;

    Abstract : Verification of users’ identities are normally carried out via PIN-codes or ID- cards. Biometric identification, identification of unique body features, offers an alternative solution to these methods. Fingerprint scanning is the most common biometric identification method used today.
