  4. 23. Variable selection for generalized linear mixed model by L1 penalization for predicting clinical parameters of ovarian cancer

    Kandidat-uppsats, Lunds universitet/Matematisk statistik

    Författare :Lan Hoa Diep; [2021]
    Nyckelord :Mathematics and Statistics;

    Sammanfattning : The quantity of biomarkers, which are proteins in this case, in ovarian cancer (OC) tumor and immune tissue regions of interest (ROIs) were measured with the new technology Digital Spatial Profiler (DSP). These measurements were used to construct regression models on the biomarkers to predict for two clinical parameters; tumor type (”Type 1” vs ”Type 2”) and the immune infiltration type (”Cavities” vs ”Dispersed”).

  5. 24. Long-term forecasting model for future electricity consumption in French non-interconnected territories

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :MATHIEU CARON; [2021]
    Nyckelord :Long-term forecasting; electricity demand; peak demand; energy planning; clustering analysis; artificial neural network; generalized additive model; Långsiktig prognostisering; elbehov; topplast; energiplanering; klusteranalys; artificiellt neuralt nätverk; generaliserad tillsatsmodell;

    Sammanfattning : In the context of decarbonizing the electricity generation of French non-interconnected territories, the knowledge of future electricity demand, in particular annual and peak demand in the long-term, is crucial to design new renewable energy infrastructures. So far, these territories, mainly islands located in the Pacific and Indian ocean, relies mainly on fossil fuels powered facilities. LÄS MER

  7. 25. Canine stress responses : a study on the impact of petting on behaviour, saliva cortisol and heart rate of dogs

    Master-uppsats, SLU/Dept. of Animal Environment and Health

    Författare :Tanmayee Anil Chaudhary; [2021]
    Nyckelord :petted; not-petted; behaviour; body postures; vocalisation; saliva cortisol; heart rate;

    Sammanfattning : From previous researches it has been shown that dogs being petted by familiar people show more calming gestures and social approach. The aim of this experiment was to investigate whether a 5-minute tactile stimulation reduces or buffers the stress reaction in dogs. The participants were 20 privately owned dogs and their owners.
