  1. 21. Multimodal Brain Age Estimation

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Oscar Danielsson; [2020]
    Keywords : ;

    Abstract : Machine learning models trained on MRI brain scans of healthy subjects can be used to predict age. Accurate estimation of brain age is important for reliably detecting abnormal aging in the brain. One way to increase the accuracy of predicted brain age is through using multimodal data. READ MORE

  3. 22. Generating synthetic brain MR images using a hybrid combination of Noise-to-Image and Image-to-Image GANs

    University essay from Linköpings universitet/Statistik och maskininlärning

    Author : Lennart Schilling; [2020]
    Keywords : Generative Adversarial Network; GAN;

    Abstract : Generative Adversarial Networks (GANs) have attracted much attention because of their ability to learn high-dimensional, realistic data distributions. In the field of medical imaging, they can be used to augment the often small image sets available. READ MORE

  4. 23. Implementation and verification of a quantitative MRI method for creating and evaluating synthetic MR images

    University essay from Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)

    Author : Aleksander Blagoiev; [2020]
    Keywords : MRI; Quantitative MRI; Synthetic MRI;

    Abstract : The purpose of this thesis was to implement and quantitatively test a quantitative MRI (qMRI) method, from which synthetic MR images are created and also evaluated. The parameter maps of T1, T2*, and effective proton density (PD*) were tested with reference tubes containing different relaxation times, and concentrations of water (H2O) and heavy water (D2O).

  5. 24. Gallringens effekter på botten- och fältskikt i grandominerad produktionsskog : en studie av hur störning kan påverka β-diversitet i Norrland och Svealand

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

    Author : William Jaktén Langert; Andreas Widell; [2020]
    Keywords : biodiversitet; bottenskikt; fältskikt; störning; gallring; boreal skog;

    Abstract : Den boreala skogens beståndsstruktur har historiskt primärt präglats av brand, vilket skapat en flerskiktad beståndsstruktur. Störning är därför en avgörande faktor för artmångfald i dessa ekosystem. READ MORE

  6. 25. Hur påverkas hjärtfrekvens och blodlaktat av T1/T3 (tölt)finalens utformning?

    University essay from SLU/Dept. of Anatomy, Physiology and Biochemistry

    Author : Sangsta Elsa Eriksson; [2020]
    Keywords : islandshäst; tävling; fysiologiskt svar; tölt; laktat; träning; hjärtfrekvens;

    Abstract : Effects of walk breaks in T1/T3 final on heart rate and lactate in Icelandic horses Icelandic horses share, with a few other breeds, the genes to perform the gaits tölt (fourbeat without suspension) and flying pace (two-beat with suspension). Characteristic for a good tölt is the clear and distinct four beat, great balance, correct topline and high but supple movements. READ MORE
