  1. 6. Energiförluster från vs-rör med intilliggande balkong : Parameterstudie i Comsol Multiphysics

    Master-uppsats, Karlstads universitet

    Författare :Adam Åberg; [2023]
    Nyckelord :vs-rör; energiförluster; balkong; egcobox; flebostadshus;

    Sammanfattning : Energy issues are today in high priority nationally and internationally as its impact on the environment and climate has become increasingly apparent. The real estate sector accounts for 34 % of Sweden's total energy consumption, where 70 % goes to heating apartment buildings. LÄS MER

  3. 7. Hydrogen storage systems : Methodology and model development for hydrogen storage systems performance evaluation based on a transient thermodynamic approach

    Master-uppsats, Mälardalens universitet/Akademin för ekonomi, samhälle och teknik

    Författare :Kreshnik Margaritari; [2023]
    Nyckelord :Hydrogen; Hydrogen storage system; Hydrogen filling process; Hydrogen storage system operation; Hydrogen storage system design; Hydrogen fast filling; Hydrogen tank modelling;

    Sammanfattning : The overall performance of a hydrogen storage system can be affected by various parameters, such as operation and design parameters, but also by the state of the hydrogen contained inside the storage tanks. In this work, a methodology is developed to evaluate the state of the hydrogen during the filling process and its impact on the overall system performance under variable operation conditions and design parameters.

  4. 8. Formula Student Car Stability

    Kandidat-uppsats, Lunds universitet/Institutionen för energivetenskaper

    Författare :Oliver Belfiore; [2023]
    Nyckelord :Racing; Car; Vehicle; dynamics; vehicle dynamics; Technology and Engineering;

    Sammanfattning : This thesis investigates the impact of varying passive components on the stability of a Formula Student race car. The study was conducted using a 7-post model and a lateral model, both of which were derived using Lagrangian methods and state-space modelling techniques. These models were then validated and adjusted using logged data. LÄS MER

  5. 9. MODELLING OF HEAT TRANSFER OF RAILWAY SWITCH HEATING

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

    Författare :Siddharth Suresh Sumathi; [2023]
    Nyckelord :Conjugate Heat transfer analysis; transient analysis; CFD; insulation; measurement data uncertainties.; Konjugat Värmeöverföringsanalys; transientanalys; CFD; isolering; mätdata osäkerheter.;

    Sammanfattning : Switches and crossings are vital components of the railway network. Obstacles to the smooth functioning of these components could result in delays and network traffic. Given the geographical location of Sweden, snow is one of the major obstacles for the switches. LÄS MER

  7. 10. Patienters upplevelse av postoperativ konfusion på vårdavdelning

    Kandidat-uppsats, Uppsala universitet/Institutionen för folkhälso- och vårdvetenskap

    Författare :Josefin Qvist; Emilia Sigrén; [2023]
    Nyckelord :Postoperative complications; emergence delirium; patient experience; nursing; nursing science; Postoperativ komplikation; akut konfusion; patientupplevelse; omvårdnad; vårdvetenskap;

    Sammanfattning : Background: Emergence delirium is a transient change in mental function and is a common complication in the postoperative period. The condition is characterized by emotional disturbances, lack of ability to think clearly, disorientation and hallucinations. LÄS MER
