  1. 1. Rehabiliteringsmetoder för hundar efter operation av osteokondros i bogleden : en enkätstudie riktad till djurhälsopersonal och icke-djurhälsopersonal i Sverige

    University essay from SLU/Dept. of Clinical Sciences

    Author : Anna Färnström; Emelie Larsson; [2022]
    Keywords : artroskopi; djurhälsopersonal; fysioterapi; OCD; osteokondros dissecans; rehabilitering;

    Abstract : Osteokondros (OC) och osteokondros dissecans (OCD) i bogleden är vanliga tillväxtrubbningar och utvecklingssjukdomar hos unga hundar av medel- till stora raser. Dessa sjukdomar behandlas ofta kirurgiskt och den vanligaste metoden för både diagnostik och åtgärd är artroskopi. READ MORE

  2. 2. The Development of a Model for Determining the Spatial Resolution of Pulsed-Neutron Sources

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

    Author : Michael Byrnes; [2022]
    Keywords : Physics and Astronomy;

    Abstract : This project entails the development of a model for determining the spatial resolution in scanning applications of pulsed-neutron sources, such as at the European Spallation Source (ESS). The development of this model involves the simplification of the problem of representing a pulse neutron scanning across a sample by approximating the pulsed neutron beam as a continuous laser beam scanning across a one dimensional object of known dimensions.

  3. 3. Time-resolved x-ray diffraction study of longitudinal optical phonons in zincblende semiconductors

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

    Author : Lassi Linnala; [2022]
    Keywords : femtosecond THz radiation; ultrafast x-ray diffraction; pump-probe; longitudinal optical phonons; zincblende semiconductors; anharmonic decay; density functional perturbation theory; Physics and Astronomy;

    Abstract : Anharmonic decay of longitudinal optical (LO) phonons in zincblende semiconductors is not at present well characterized due to the polar and many-body nature of the problem. Femtosecond THz radiation offers a novel route to this study, as the interaction of this radiation is directly with the phonon lattice and these THz excited phonons do not have enough energy to excite electrons over the band gap.

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

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

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

    Abstract : 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. READ MORE

  5. 5. Defect classification in LPBF images using semi-supervised learning

    University essay from Karlstads universitet/Institutionen för matematik och datavetenskap (from 2013); Karlstads universitet/Avdelningen för datavetenskap

    Author : Anton Göransson; [2022]
    Keywords : Additive manufacturing; Laser powder bed fusion; Machine learning; Siamese neural networks; Deep learning; Defect classification;

    Abstract : Laser powder bed fusion is an additive manufacturing technique that is capable of building metallic parts by spreading many layers of metal powder over a build surface and using a laser to melt specific sections of the surface. The part is built by melting consecutive layers on top of each other until the design is completed. READ MORE
