1. 21. Imaging of the Cytosolic Antibody Receptor TRIM21

   Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

   Författare :Þórunn Stefánsdóttir; [2022]
   Nyckelord :TRIM21; ProteinStructure; Antibody; cryo-EM; Gel-Filtration SizeExclusion Chromatography ; Immunology; ProteinPurification; SDS-PAGE; TRIM21; Proteinstruktur; Antikroppar; cryo-EM; Gel-filtreringsKromatografi; Immunologi; ProteinRening; SDS-PAGE;

   Sammanfattning : TRIM21 is a cytosolic ubiquitin ligase and an antibody receptor that providesa last line of defense against invading pathogens. By utilizing the diversity ofantibody repertoire to identify pathogens, TRIM21 serves as a link betweenintrinsic cellular defense and adaptive immunity. LÄS MER

3. 22. Towards topology-aware Variational Auto-Encoders : from InvMap-VAE to Witness Simplicial VAE

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

   Sammanfattning : Variational Auto-Encoders (VAEs) are one of the most famous deep generative models. After showing that standard VAEs may not preserve the topology, that is the shape of the data, between the input and the latent space, we tried to modify them so that the topology is preserved.

4. 23. Increased Displacement in Magnetomotive Ultrasound Imaging by Adding a Homogeneous Magnetic Field

   Master-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknik

   Författare :Jules Reniaud; [2022]
   Nyckelord :Technology and Engineering;

   Sammanfattning : Magnetomotive Ultrasound, MMUS, is an imaging modality used to reveal a magnetic contrast agent using an external time-varying inhomogeneous magnetic field. By this, the particles are set in motion, and the motion is detected with ultrasound. LÄS MER

5. 24. The Effect of Alternative Tungsten Carbide Grain Size Distribution on Microstructure and Mechanical Properties in Cemented Carbides

   Master-uppsats, KTH/Materialvetenskap

   Författare :Filip Ivarsson; [2022]
   Nyckelord :Cemented Carbides; WC Grain Size Distribution; Mechanical Properties; Microstructure Analysis; Hårdmetall; WC Kornstorleksfördelning; Mekaniska Egenskaper; Mikrostruktur Analys;

   Sammanfattning : In the constant pursuit of better-performing cemented carbides, recent studies suggest that a combination of better hardness and toughness can be obtained by changing its WC grain size distribution. As the area is still rather unexplored, this  thesis  aims  to  broaden  the  knowledge  and  answer  whether mechanical properties can be changed by changing the WC grain size distribution, in the context of mining drill bit inserts.

7. 25. Quantification and Detection of Motion Artifacts in Laser Speckle Contrast Imaging

   Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

   Författare :Dennis Amphan; [2022]
   Nyckelord :Laser speckle contrast imaging; Image registration; Motion artifacts; Detection;

   Sammanfattning : Laser speckle contrast imaging (LSCI) is a non-invasive method for assessment of microcirculatory blood flow. The technique is based on analysis of speckle patterns to build 2D maps of perfusion with high spatial and temporal resolution. LÄS MER
