  1. 11. Can an alternative cosmovision challenge the market hegemony? : an analysis of article 6.8 in the Paris agreement

    Master-uppsats, SLU/Dept. of Urban and Rural Development

    Författare :Amanda Björksell; [2023]
    Nyckelord :climate negotiations; Paris agreement; Buen Vivir; ; Vivir Bien; article 6.8; climate justice; Bolivia; non-market approaches;

    Sammanfattning : A rising global temperature and increased emissions, in combination with the slow progress of the yearly climate negotiations shows that there is something hindering the radical improvement needed to protect both the planet and humanity. The outset for this thesis is to study the UN climate negotiations and the alternative discourse that can question the hegemony. LÄS MER

  3. 12. Optimization of Thermal Comfort on Electric Buses : A Comprehensive Study on Passenger Satisfaction in Stockholm, Sweden

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

    Författare :Ellinor Hambraeus; Maxwell Minotta Cuervo; [2023]
    Nyckelord :Electric bus; Bus temperature; Thermal comfort; Energy efficiency; Predicted Mean Vote; Equivalent temperature v; Elbuss; busstemperatur; termisk komfort; energieffektivisering; Predicted Mean Vote; Ekvivalent temperatur vii;

    Sammanfattning : The transition towards electrification in the bus sector is necessary to achieve the global climate goals and has gained significant traction in recent years. However, there are critical challenges associated with this transition, one of them being the absence of excess heat that traditional combustion engines provided to warm the bus cabin. LÄS MER

  4. 13. Where there is road, there is fire (influence): An exploratory study on the influence of roads in the spatial patterns of Swedish wildfires of 2018

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

    Författare :Gabriel Romeo Ferriols Pavico; [2023]
    Nyckelord :Geography; GIS; Wildfire; Fire Spatial Patterns; Road; Conformity; FWI; Earth and Environmental Sciences;

    Sammanfattning : This study focuses on the Swedish wildfire season of 2018, when the country incurred ten times more than the average burnt area that occurred in previous years. The study aims to address a broad research question: Do roads influence the size of the burned area? This study fills the gap in research on the effects of roads in the spatial patterns of wildfires.

  5. 14. AC Gate Bias Stress of 4H-SiC MOSFETs : An investigation into threshold voltage instability of SiC Power MOSFETs under the influence of bipolar gate stress

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

    Författare :Agnimitra Saha; [2023]
    Nyckelord :Silicon Carbide; Gate Bias Stress; Threshold Voltage; On-state Resistance; Temperature; kiselkarbid; gate spännings-stress; tröskelspänning; on-resistansen; temperatur;

    Sammanfattning : Silicon Carbide, a wide band gap (WBG) semiconductor, has pushed electrical limits beyond Silicon (Si) when it comes to power electronics. It has offered the electrification of society showing promise for a greener future. LÄS MER

  7. 15. Evaluating the Performance of Propulsion System Elements in an Aerospace Company

    Master-uppsats, KTH/Kraft- och värmeteknologi

    Författare :David Fredouelle; [2023]
    Nyckelord :Turbomachinery; injector; test campaign; cryogenic; rocket engine; test bench; cold flow; Turbomaskin; injektor; testkampanj; kryogen; raketmotor; testbänk; kallt flöde;

    Sammanfattning : This paper examines two examples of testing activities of sub-components of a 300kN methalox first-stage rocket engine developed by Pangea Aerospace, namely, theinjectors and the cryogenic pumps. One of the difficulties of these test campaignsis to evaluate the performances of these sub-components without using cryogenicpropellants and in conditions differing from flight conditions. LÄS MER
