  1. 11. EV battery temperature estimation : Designing a model for minimal temperature of high-voltage battery in a BEV

    University essay from Mittuniversitetet/Institutionen för data- och elektroteknik (2023-)

    Author : Björn Arvidsson; [2023]
    Keywords : BEV; temperature estimation; lowpass filter; BEV; lågpassfilter; temperaturestimering;

    Abstract : Fordonsindustrin är inne i ett skifte, där förbränningsmotorer (ICE) bör-jar fasas ut och det satsas mer på eldrift med hjälp av batterier (BEV).  I detta arbete, som efterfrågades av Volvo Cars, utvecklades en matema-tisk modell som uppskattar den lägsta temperaturen i en elbils högspän-ningsbatteri.

  3. 12. Impact of Residual Stress on the Warm Pre-Stressing Effect

    University essay from KTH/Hållfasthetslära

    Author : Emil Danielsson; [2023]
    Keywords : Warm Pre-Stressing effect; Residual stress; Cleavage fracture; Ferritic Steel; Fracture mechanics; Varm förspänning; Restspänningar; Klyvbrott; Brottmekanik; Ferritiskt stål;

    Abstract : Irradiation of a reactor pressure vessel (RPV) causes a shift of the ductile to brittle transition region towards higher temperature regions. In the event of a pressurized thermal shock (PTS), where the temperature drops drastically, the ductile to brittle transition region might be entered for irradiated ferritic steel. READ MORE

  4. 13. Estimating Ambient Temperature using Internal Sensors and Thermal Modelling in Mobile Phones

    University essay from Lunds universitet/Institutionen för reglerteknik

    Author : Isak Evaldsson; Henrik Paulcén; [2023]
    Keywords : Technology and Engineering;

    Abstract : This thesis studies the possibility of estimating the ambient temperature around a mobile phone using its internal temperature sensors. The thesis aims to develop and evaluate ambient temperature models that use internal temperature sensors within the device and, from a manufacturer’s perspective, investigate if the models for ambient temperature can be enhanced by tailoring them to the internals of specific devices.

  5. 14. Phase Transitions in the Two-Higgs-Doublet Model with a Softly-Broken Z2 Symmetry

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

    Author : Filip Gustavsson; [2023]
    Keywords : Particle Physics; Beyond Standard Model; Two-Higgs Doublet Model; 2HDM; Electroweak Phase Transitions; Strong First-order Phase Transition; Dimensional Reduction; CP-conserving; Softly broken Z2-symmetry; Physics and Astronomy;

    Abstract : The two-Higgs-doublet model (2HDM) is an extension to the Standard Model which adds a second Higgs doublet. This extension provides freedom within the model, in comparison to the Standard Model, which makes it possible to study strong electroweak phase transitions. READ MORE

  6. 15. Investigation of different ventilation profiles to avoid stratification in Nearly Zero Energy Buildings

    University essay from Högskolan i Gävle/Energisystem och byggnadsteknik

    Author : Alazne Irene Varela Santana; [2023]
    Keywords : stratification; water model; comfort; mixing; temperature; potential energy; net zero energy building;

    Abstract : This research paper examines possible solutions for the problems that warm air heating is suffering in Nearly Zero Energy Buildings. These NZEBs are passive houses constructed to have high energy efficiency where the quantity of power used is equal to the power created annually, produced locally or in the surroundings by renewable energy sources.
