  1. 21. Common Guillemots Uria aalge Alter Trip Patterns During Breeding

    Kandidat-uppsats, SLU/Dept. Of Aquatic Resources

    Författare :Mica Bohacek; [2022]
    Nyckelord :Common Murre; Stora Karlsö; trip duration; trip frequency; central-place foragers; feeding rate; time-budget;

    Sammanfattning : Seabirds are facing immense pressures, primarily induced by competition with commercial fisheries; this is of considerable concern due to the critical role that they play in marine food webs and their invaluable function as bioindicators. In this thesis, I studied the temporal change in trip duration for the Common Guillemot Uria aalge, a circum-arctic seabird species. LÄS MER

  3. 22. Tracking Under Countermeasures Using Infrared Imagery

    Master-uppsats, Linköpings universitet/Datorseende

    Författare :Sara Modorato; [2022]
    Nyckelord :computer vision; infrared imagery; tracking; countermeasures; discriminative correlation filters; Efficient Convolution Operator tracker; Spatial-Temporal Regularized Correlation Filter tracker; Visual Object Tracking; flare; DIRCM; multiple wavelength bands; features;

    Sammanfattning : Object tracking can be done in numerous ways, where the goal is to track a target through all frames in a sequence. The ground truth bounding box is used to initialize the object tracking algorithm. Object tracking can be carried out on infrared imagery suitable for military applications to execute tracking even without illumination. LÄS MER

  4. 23. Optimering av 15O-vatten-metoden för bedömning av vänsterkammarens volym och funktion

    Magister-uppsats, Uppsala universitet/Institutionen för kirurgiska vetenskaper

    Författare :Jonathan Sigfridsson; [2022]
    Nyckelord :Positron Emission Tomography; 15O-water; Cardiology; Left Ventricle-Function; Positronemissionstomografi; 15O-vatten; Kardiologi; Vänsterkammarfunktion;

    Sammanfattning : Bakgrund: Uträkning av vänsterkammarens (VK) volymer (Enddiastolisk volym, EDV; Endsystolisk volym, ESV; Slagvolym, SV) och ejektionsfraktion (EF) går att göra med elektrokardiografi (EKG)-styrd gating vid positronemissionstomografi (PET) med spårämnet 15O-vatten. Metoden behöver utredas noggrannare och optimeras för att kunna introduceras i klinisk rutinverksamhet. LÄS MER

  5. 24. Spatio-temporal drought characteristics in the Limpopo basin from 1918 to 2018 - A case study based on analysis of the Standardized Precipitation Evaporation Index (SPEI)

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Sandra Domingos Sambo; [2021]
    Nyckelord :rdought; Standardized Precipitation Evapotranspiration Index; Limpopo River basin; Normalized difference vegetation index; Mann-Kendall Test; Correlation analysis; Earth and Environmental Sciences;

    Sammanfattning : The identification of the characteristics of drought are of great importance in water resources planning and management. This study explored the characteristics of drought at Limpopo River Basin (LRB) from 1918 to 2018. LÄS MER

  7. 25. Application of data-driven models in exploring cyanobacterial bloom risks in Lake Mälaren

    Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Abigail Huertas Herrera; [2021]
    Nyckelord :Random Forest; blue-green algae; WHO Alert Level Framework; drinking water supply; cyanobacterial blooms;

    Sammanfattning : Cyanobacteria are a unique organism, a bacterium that develop photosynthesis, thus it contains chlorophyll, a pigment commonly associated to algae. For this reason, cyanobacteria are also known as blue-green algae. One of the secondary metabolites of cyanobacteria is cyanotoxin, a substance which is hepatoxic, neurotoxic, and dermatoxic. LÄS MER
