  1. 6. First principles investigation of the thermal conductivity of Zr, ZrC, and ZrN

    University essay from KTH/Fysik

    Author : Daniel Karlsson; [2023]
    Keywords : Electron-phonon interaction; Density functional theory; Boltzmann transport equation; first-principles; thermal conductivity; electrical resistivity; Abinit; Phono3py; Elektron-fononväxelverkan; täthetsfunktionalteori; Boltzmanns transportekvation; värmeledningsförmåga; elektrisk resistivitet; Abinit; Phono3py;

    Abstract : The thermal conductivity and electrical resistivity of Zr, ZrC, and ZrN were calculated using first-principles density functional theory (DFT) and the Boltzmann transport equation. The electron-phonon scattering was modeled via the self-energy relaxation time approximation (SERTA), and the phonon-phonon scattering via the analogous single-mode relaxation time approximation (SMRTA).

  3. 7. Constructing a Social Profitability Index: Socially Responsible Investing in Electric Utilities

    University essay from Handelshögskolan i Stockholm/Institutionen för finansiell ekonomi

    Author : Odessa Bäckfors; Ebba Jernmark Burrows; [2023]
    Keywords : Socially responsible investing; Social Profitability Index; Sustainability ratings; Shareholder activism; Renewable electricity;

    Abstract : Building on a theory about the Social Profitability Index (SPI), this paper is the first to construct an SPI in practice ranking investment opportunities based on social and financial returns within the electric utility industry. The social return is the investor-preference weighted social gain from avoiding carbon emissions by changing to renewable production technology in a firm. READ MORE

  4. 8. The Paradigm Shift for Substations Technology within Wind Power Applications from Onshore to Floating

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Ahmad Talaat Hifzy; [2023]
    Keywords : Floating; offshore; substation; transformer; GIS; equipment; high-voltage; fatigue; Flytande; havsbaserad; station; transformator; GIS; utrustning; högspänning; utmattning;

    Abstract : Floating wind turbines are attracting more attention as more than three-quarters of the total offshore technical potential is located in deep water, leading to a growing trend in floating wind farm projects. Consequently, it becomes necessary to develop Floating Offshore Substation (FOSS) to step up voltage and efficiently transmit power to the shore with minimal losses. READ MORE

  5. 9. Let Us Put Our Brains in the Spotlight – Literally!

    University essay from Lunds universitet/Examensarbeten i molekylärbiologi

    Author : Elsa Karjalainen; [2023]
    Keywords : Biology and Life Sciences;

    Abstract : Neurons are the working force in each vertebrate’s nervous system. These small cells have the important task of transferring information in the form of electrical charges called action potentials. Neurons make it possible for us to sense touch, process our environment, and store memory. READ MORE

  6. 10. Shaping Awareness Around Electric Vehicle Driver's Power Load on the Electric Grid

    University essay from Uppsala universitet/Institutionen för informationsteknologi

    Author : Yakira Pulido Moreno; [2023]
    Keywords : ;

    Abstract : This thesis researched how electric vehicle users in Uppsala county could be encouraged to change their charging habits, such that they avoid contributing to power peaks in the electrical grid, using only non-monetary incentives. The application area was in Dansmästaren, a parking building with multiple charging stations for electrical vehicles. READ MORE
