  3. 2. Assessment of hydrogen supply chain for transport sector of Sweden

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :José Maria Soares Rodrigues; [2023]
    Nyckelord :Hydrogen; Hydrogen Supply Chain; Elecrolysis; 2030; Sweden; Electricity prices; MILP; Optimization; Vätgas; Vätgassupplykedja; Elektrolys; 2030; Sverige; Elpriser; MILP; Optimering;

    Sammanfattning : Fuel cell electric vehicles, powered by hydrogen are an enticing alternative to fossil-fuel vehicles in order to reduce greenhouse gas emissions and consequently accomplish the environmental targets set to tackle the environmental crisis. It is crucial to develop the appropriate infrastructure if the FCEVs are to be successfully accepted as an alternative to fossil-fuel vehicles. LÄS MER

  4. 3. Implementing SAE Techniques to Predict Global Spectacles Needs

    Master-uppsats, Högskolan Dalarna/Institutionen för information och teknik

    Författare :Yuxue Zhang; [2023]
    Nyckelord :small area estimation; area-level model; empirical best linear unbiased prediction EBLUP ; generalized linear mixed models; Conditional Autoregressive; spatial correlation; spectacle needs; assistive products; auxiliary data; hglm; relative standard error; simulation;

    Sammanfattning : This study delves into the application of Small Area Estimation (SAE) techniques to enhance the accuracy of predicting global needs for assistive spectacles. By leveraging the power of SAE, the research undertakes a comprehensive exploration, employing arange of predictive models including Linear Regression (LR), Empirical Best Linear Unbiased Prediction (EBLUP), hglm (from R package) with Conditional Autoregressive (CAR), and Generalized Linear Mixed Models (GLMM).

  5. 4. Exploring the factors affecting tree establishment after wildfire in a boreal forest in Sweden

    Master-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildning

    Författare :Robert Pim; [2023]
    Nyckelord :tree regeneration; tree establishment; wildfire; boreal forests; disturbance; sapling regeneration; generalized linear mixed models;

    Sammanfattning : The factors affecting tree establishment in boreal forests after fire will help determine the community composition of the regenerating forest. These may have large consequences on the community dynamics for years after the fire disturbance. LÄS MER

  7. 5. Wild boar habitat selection in south-central Sweden's forested habitats : effects of season and time

    Master-uppsats, SLU/Dept. of Ecology

    Författare :Bengt Arvid Norström; [2023]
    Nyckelord :wild boar; habitat selection; GLMM; Sweden;

    Sammanfattning : How wild boar utilize space, interact, and affect its surroundings is critical for understanding their ecology. Wild boar populations have increased rapidly in Sweden and continue to expand its distributional range further north. LÄS MER
