  1. 1. Potential of tall oil pitch as phase change material in lignin-shelled hybrid nanocapsules for thermal energy storage.

    Master-uppsats, Mittuniversitetet/Institutionen för kemiteknik

    Författare :Helena Viberg Nissilä; [2022]
    Nyckelord :phase change materials PCM ; tall oil pitch TOP ; lignin; nanocapsules; hybrid material; thermal storage;

    Sammanfattning : A prospect in utilizing thermal energy in development of energy systems is by the useof phase change materials (PCMs). PCMs are materials that can store and releaseenergy during phase changes, e.g. from solid to liquid. LÄS MER

  3. 2. Numerical Simulation of 3.3 kV–10 kV Silicon Carbide Super Junction-MOSFETs for High Power Electronic Applications

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

    Författare :Rishi Balasubramanian Saraswathy; [2022]
    Nyckelord :Super–Junction; DMOSFET; 4H-SiC; Silicon Carbide; Wide bandgap; 6.5 kV; 10 kV; On-state resistance; Breakdown voltage; Super–Junction; DMOSFET; 4H-SiC; kiselkarbid; bredbandgap; 6.5 kV; 10 kV; framspänningsfall; spärrspänning;

    Sammanfattning : The thesis focuses on designing and characterizing SiC 3.3 kV Diffused Metal-Oxide Semiconductor Field-Effect Transistor (DMOSFET)s with a Ron that is significantly lower than that of current commercial devices. The On-state resistance and breakdown voltage are then adjusted by adding a Super-Junction structure. LÄS MER

  4. 3. Embracing Transformative Technology to End Worker Exploitation : How Individual Resistance to Change Management Can Explain the Limited Adoption of Worker Monitoring Tools in Multinational Organizations.

    Kandidat-uppsats, Jönköping University/IHH, Företagsekonomi

    Författare :Alek Kahn; Yiping Jiang; Måns Nilsson; [2021]
    Nyckelord :forced labor; technology; social sustainability; CSR; monitoring tools; digital monitoring; resistance to change; technology change;

    Sammanfattning : Background: The unethical treatment of factory workers is widespread, especially in developing countries. There is no international legal body with the jurisdiction to uphold universal labor rights. Hence, the responsibility to ensure worker well-being falls upon the multinational organizations that operate the supply chain. LÄS MER

  5. 4. Examination and Design of Propeller Configurations foran Electrically Powered Hydrofoil Vehicle

    Master-uppsats, KTH/Marina system

    Författare :Joakim Wallberg; [2018]
    Nyckelord :;

    Sammanfattning : The thesis examines propeller configurations for the propulsion system for the water mode in the amphibious craft concept Newt, which also includes contra-rotating propellers. Newt is a research project on innovative commuter vehicles carried out by the naval architecture department at KTH. LÄS MER

  7. 5. Är gräset grönare på andra sidan? : en studie kring naturgräsplaner i fotbollsarenor

    Kandidat-uppsats, SLU/Dept. of Biosystems and Technology (from 130101)

    Författare :Robin Kalenius; [2015]
    Nyckelord :fotboll; turf; Poa pratensis; Lolium perenne; rotelongering; etylen; gibberellin; vinterhärdighet; Swedbank Stadion; pimpsten;

    Sammanfattning : De stora fotbollsligorna i Europa spelar höst till vår, medan vi i Sverige spelar vår till höst. Då vi i Sverige kan se problematik med låg täckningsgrad och slitna gräsmattor under vår säsong, vad händer om vi skulle spela mellan höst till vår? UEFA ställer krav på att fotbollsplanen skall vara spelbar för alla matcher under säsongen. LÄS MER
