  1. 1. Assessment of Climate Change Impact on Rainfed Barley Production in the Mediterranean Basin : The Almeria province case study

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

    Författare :Francesco Saretto; [2024]
    Nyckelord :Barley; Rainfed; Climate Change; AquaCrop; AquaCrop-OSPy; Mediterranean; Climate Change Adaptation; Crop Modeling; Agriculture; Irrigation;

    Sammanfattning : The Mediterranean basin is widely recognized as a climate change hotspot, with climate models projecting increasingly warmer and drier conditions that will impact local ecosystems, communities, and economies. Agriculture will be among the most affected sectors, with harsher conditions for crops’ growth, greater water needs, and lower yields. LÄS MER

  3. 2. Alternative logistic routes and their aggregate effect on the use of infrastructure : the potential of using multiple routes in the Samgods model

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för ekonomi, teknik, konst och samhälle

    Författare :Anton Åkerström; Sebastian Morel; [2023]
    Nyckelord :Samgods; Discrete Choice Models;

    Sammanfattning : The primary objective of this thesis is to assess the different statistical methods used forcalibrating the Samgods model, which is a transportation planning tool employed in Sweden toforecast the demand for freight transport. By focusing on the specific context of national logisticsmodels, this research aims to enhance the accuracy and reliability of the Samgods model throughproposed improvements. LÄS MER

  4. 3. Investigation of current sensing techniques for a high bandwidth application : Focusing on Hall-Current Sensing

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

    Författare :Enric Ametller; [2023]
    Nyckelord :Current sensing; High bandwidth; Inverter; Hall-sensors; Strömavkänning; Hög bandbredd; Inverter; Hall-sensorer;

    Sammanfattning : With the ongoing surge in electrification within the automotive industry, the demand for high-power inverters is steadily on the rise. Furthermore, these inverters are now expected to handle increased power loads while maintaining enhanced efficiency. LÄS MER

  5. 4. Evaluating a new hydraulic implementation in LPJ-GUESS for three sites in north Europe

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

    Författare :Carl Holmquist; [2023]
    Nyckelord :Physical Geography and Ecosystem analysis; LPJ-GUESS; drought; sensitivity analysis; evapotranspiration; gross primary production; hydraulic parameters; boreal forest.; Earth and Environmental Sciences;

    Sammanfattning : Drought is projected to increase in frequency and intensity and impacts trees with increased water stress and increased mortality rate. Water stresses can cause hydraulic failure-related mortality or carbon starvation due to tree species having different strategies to deal with water stresses. LÄS MER

  7. 5. Parameter Stability in Additive Normal Tempered Stable Processes for Equity Derivatives

    Master-uppsats, Mälardalens universitet/Akademin för utbildning, kultur och kommunikation

    Författare :Eduardo Alberto Alcantara Martinez; [2023]
    Nyckelord :Parameter Stability; Lévy Processes; Calibration; Volatility Surface; Subordination; Additive Normal Tempered Stable Processes; Stable Distribution; Variance Gamma Process; Normal Inverse Gaussian Process.;

    Sammanfattning : This thesis focuses on the parameter stability of additive normal tempered stable processes when calibrating a volatility surface. The studied processes arise as a generalization of Lévy normal tempered stable processes, and their main characteristic are their time-dependent parameters. LÄS MER
