  1. 1. Tandstensborttagning med ultraljudstandborste : en pilotstudie

    University essay from SLU/Dept. of Clinical Sciences

    Author : Lina Dolfei; Molly Lavesson; [2023]
    Keywords : CleanyTeeth; emmi-pet; hund; munhälsa; plack; parodontal sjukdom; tand; tandborstning; tandsten; tandvård; veterinärmedicinsk tandvård;

    Abstract : Tandsten är ett vanligt förekommande problem hos våra hundar. Tandsten i sig är inte patologiskt men främjar fortsatt tillväxt av plack och bakterier vilket kan leda till parodontal sjukdom. READ MORE

  3. 2. Machine Learning of Laser Ultrasonic Data to Predict Material Properties

    University essay from Linköpings universitet/Statistik och maskininlärning

    Author : Filip Tuvenvall; [2023]
    Keywords : Machine Learning; Laser Ultrasonics; Material Properties; Steel; Hardness of Steel;

    Abstract : The hardness of steel is an important quality parameter for several industrial applications. Conventional mechanical testing is used in quality testing for material hardness and the method is time-consuming, can cause material mix-ups, and results in material waste. READ MORE

  6. 5. Characterization of surface defects caused by ultrasonic cleaning of aluminium

    University essay from Uppsala universitet/Tillämpad materialvetenskap

    Author : Emanuel Eriksson; [2022]
    Keywords : Ultrasonic cleaning; surface cleaning; metal; aluminium; 7050; 2050; defects; surface defects; Energy Dispersive Spectroscopy; Scanning Electron Microscopy; Vertical Scanning Interferometry;

    Abstract : This master thesis studies the behaviour of two aluminium alloys in ultrasonic cleaning at two different intensities, as well as the effect of a cleaning solution, Formula 815 GD-NF on the same surface have been studied with respect to surface roughness and material composition. Methods like Light Optical Microscopy (LOM), Scanning Electron Microscopy (SEM), Energy Dispersive Spectroscopy (EDS) and 3D topography using white light interferometry (VSI) was used to study the surface and material composition.
