  1. 16. Day or night? Testing thermal imaging technology for estimating ungulate population densities in southern Sweden

    University essay from SLU/Southern Swedish Forest Research Centre

    Author : Julia Nowak; [2023]
    Keywords : monitoring; ungulates; thermal imaging; population density; distance sampling; Dama dama;

    Abstract : To be able to make a proper judgement and choose the best management or conservation solution when working with populations of wild ungulates or any other wildlife, it is important to obtain good estimates of population densities. Inventing or improving wild animal monitoring methods is a key to protect what may be endangered or to avoid human-wildlife conflicts. READ MORE

  3. 17. DIOSES EN LA TIERRA E EL INGENIOSO HIDALGO DE LA MANCHA : VELÁZQUEZ’S SUBVERSION OF THE HABSBURG MYSTIQUE OF POWER

    University essay from Uppsala universitet/Konstvetenskapliga institutionen

    Author : Dan Hanqvist; [2023]
    Keywords : Baroque; Siglo de Oro; Portraiture; Diego Velázquez; Philip IV; Naturalism; Subversion; Habsburg Iconography; Political Iconography; Vision; Visuality; Reception; Barroco; Siglo de Oro; retrato; Diego Velázquez; Felipe IV; naturalismo; subverción; Habsburgo; Austrias; Iconografía; Iconografía política; visión; visualidad; recepción;

    Abstract : Sometimes the concrete form and skill of a work of art stand in a non-arbitrary or non-contingent relationship with the social circumstances of its facture. I hypothesise that this form and such skill was used by Diego Velázquez for artistically, socially and politically subversive purposes. READ MORE

  4. 18. Improving polarizing neutron optics by introducing 11B4C as interlayers

    University essay from Linköpings universitet/Tunnfilmsfysik

    Author : Martin Falk; [2023]
    Keywords : Thin film multilayers; Neutron optics; Neutron polarization;

    Abstract : In this report, the effects of adding 11B4C as interlayers into Fe/Si multilayers is studied. Fe/Si multilayers are commonly used for neutron polarization at large research facilities, and improving the polarizing properties would improve their efficiency. READ MORE

  5. 19. Focal Spot Optimization Using Spatial Light Modulation and a Phase Retrieval Algorithm

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

    Author : Robert Petersen; [2023]
    Keywords : Spatial Light Modulation; Phase Retrieval Algorithm; Focal Spot Optimization; Adaptive Optics; Wavefront Sensing; Lasers; Physics and Astronomy; Technology and Engineering;

    Abstract : Aberrations to the wavefront of a laser beam reduce the quality of the focal spot and are generally undesired. This project is aimed at determining the aberrations of laser beams by using a phase retrieval algorithm and to show that it is possible to correct the aberrations with a spatial light modulator to optimize the focal spot.

  6. 20. Simulation of the Filling of Epoxy in Resin Impregnated Paper Bushings : Analysis of Temperature Measurements during Filling of Epoxy and the Generation of New Filling Recipes to Avoid Cavities in the RIP Bushing

    University essay from Uppsala universitet/Avdelningen för beräkningsvetenskap

    Author : Hanna Damsgaard Falck; [2023]
    Keywords : Porous media; COMSOL Multiphysicis; Darcy s Law; Richard s Equation; Resin Impregnated Paper Bushings; RIP Bushings; Bushings; Transformers; Epoxy; Simulation;

    Abstract : The goal of the project was to create a model in COMSOL Multiphysics that can simulate thefilling of resin (epoxy) in Resin Impregnated Paper (RIP) bushings. Using the model new fillingrecipes that avoid problematic double-fronts and thereby avoid the creation of cavities in thebushings should be designed. READ MORE
