  1. 1. Prospects for a Free Electron Laser at the FemtoMAX Beamline

    Kandidat-uppsats, Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

    Författare :Johan Holmberg; [2024]
    Nyckelord :Free Electron Lasers; FEL; synchrotron radiation; MAX IV; FemtoMAX; GENESIS 1.3; XFEL; X-rays; soft X-rays; Physics and Astronomy;

    Sammanfattning : A Free Electron Laser (FEL), is a device that generates extremely coherent and brilliant radiation using electrons accelerated to relativistic velocities in a particle accelerator. The process utilises similar equipment to what is used at a synchrotron source like MAX IV, but in addition there is an interaction between the relativistic electron beam and the generated radiation to achieve an exponential growth in radiation intensity.

  3. 2. Local voltage control in a low voltage grid with high photovoltaic penetration

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Institutionen för reglerteknik

    Författare :Joakim Bakklund; [2024]
    Nyckelord :Technology and Engineering;

    Sammanfattning : This thesis examines how active power control (Volt-Watt control) and reactive power compensation (Volt-VAr control) can help limit voltage increases on the low voltage grid due to high photovoltaic (PV), installations. Due to the large increase in interest to install small scale PV-systems within residential areas the Distribution System Operator E. LÄS MER

  4. 3. Leveling the Playing Field: Can Private Investors Benefit From Mimicking Insider Trades? A quantitative study of insider trading

    Master-uppsats, Göteborgs universitet/Graduate School

    Författare :Marcus Mattsson; Marcus Lyckhage; [2023-07-04]
    Nyckelord :Insider Trading; Abnormal Return; Information Asymmetry; Outside Investors; Investment Strategy; Insider Positions;

    Sammanfattning : Historically, investors have been searching for strategies to maximize performance in the stock market. It has been shown that corporate insiders can earn abnormal returns by trading in their own companies as they possess superior information and, to a certain degree, market timing ability. LÄS MER

  5. 4. 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

  7. 5. Did Private Equity-Backed Firms Outperform Operationally During Covid-19?

    C-uppsats, Handelshögskolan i Stockholm/Institutionen för finansiell ekonomi

    Författare :Boris Bojovic; Marvin Stenersen; [2023]
    Nyckelord :Private equity; Covid-19; Operational improvements; PE-backed;

    Sammanfattning : Do private equity (PE) backed companies perform better operationally in a non-financial crisis? By analyzing PE-backed firms in the UK during Covid-19 using fixed effects difference-in-differences, our findings suggest that private equity-backed companies' performance decreased significantly more at the onset of the crisis and increased their leverage but recovered faster both with greater magnitude and significance. PE-backed companies thus seem to handle an operationally-sided crisis better over time but are more exposed to them initially. LÄS MER
