  1. 1. Estimating Diffusion Tensor Distributions With Neural Networks

    Master-uppsats, Linköpings universitet/Algebra, geometri och diskret matematik; Linköpings universitet/Tekniska fakulteten

    Författare :Rimaz Nismi; [2024]
    Nyckelord :Diffusion; Magnetic Resonance Imaging; MRI; Neural Networks; Optimal transport; Earth mover s distance; Sinkhorn distance;

    Sammanfattning : Magnetic Resonance Imaging (MRI) is an essential healthcare technology, with diffusion MRI being a specialized technique. Diffusion MRI exploits the inherent diffusion of water molecules within the human body to produce a high-resolution tissue image. An MRI image contains information about a 3D volume in space, composed of 3D units called voxels. LÄS MER

  3. 2. Compression of Sequential Voxel Data for Sequence-based Animation

    Master-uppsats, Göteborgs universitet/Institutionen för data- och informationsteknik

    Författare :Filip Antonijevic; [2023-10-23]
    Nyckelord :voxel; octree; grid; compression; animation; spatiotemporal; sorting; reordering; DXT; HSV;

    Sammanfattning : This thesis presents a method for lossy compression of voxel data in an animation sequence. Uncompressed voxel animation can become very memory intensive and therefore need a more efficient method to store and render such data. LÄS MER

  4. 3. Analysis of Mutable Game Environments Built on a Tetrahedral Mesh : Tetras, a Potential Alternative to Voxels

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Noah Tell; [2023]
    Nyckelord :Voxels; Tetrahedron; Tetrahedral Mesh; Tetrahedralization; Tessellation; Mutable Environment; Editable Terrain; Deformable Environment; Boolean Operations; Real-Time; Computer Games; Computational Geometry; Voxlar; Tetrahedror; Tetrahedralisering; Tessellering; Formbar Terräng; Booliska Operationer; Realtid; Datorspel; Beräkningsgeometri;

    Sammanfattning : Historically 3D game environments have almost always been immutable. Mutable environments are a technical challenge that will affect performance. For games of the future to continue approaching realism, mutable environments are an essential step. LÄS MER

  5. 4. Sex Differences in Dopamine D1-type Receptors and Episodic Memory : an Imaging Study Across the Adult Lifespan

    Master-uppsats, Umeå universitet/Umeå centrum för funktionell hjärnavbildning (UFBI); Umeå universitet/Institutionen för psykologi

    Författare :Anton Degerfält; [2023]
    Nyckelord :dopamine; D1DR; sex; episodic memory; ageing; PET; MRI;

    Sammanfattning : Identification of the pathways that could be targeted to alleviate ageing-related cognitive decline is of prime importance. One of the most promising target mechanisms is connected to healthy dopaminergic ageing. LÄS MER

  7. 5. Resting-state Functional Connectivity in Anhedonia: Exploring the Effects of Pramipexole

    Master-uppsats, Lunds universitet/Institutionen för psykologi

    Författare :Frida Smids; [2023]
    Nyckelord :Anhedonia; Depression; Reward; Pramipexole; Resting-state; Functional Connectivity; Nucleus Accumbens; Social Sciences;

    Sammanfattning : Pramipexole is a medication that normalises dopamine signalling in the brain. Previous studies have suggested that pramipexole is an effective treatment option for depression and anhedonia because it targets the dopaminergic pathways within the brain’s reward network. LÄS MER
