  1. 1. The Price of Power: A quantitative study of price elasticity of demand during high electricity prices in Southern Sweden

    Kandidat-uppsats, Göteborgs universitet/Institutionen för nationalekonomi med statistik

    Författare :Joel Berg; Lisa Johnsson; [2024-02-12]
    Nyckelord :;

    Sammanfattning : Unprecedentedly high electricity prices became a pressing issue for consumers in 2021-2022, causing political debate and shedding light on the hourly electricity prices. Out of the four Swedish electricity areas created to facilitate an effective electricity market, this thesis will focus on SE3 and SE4 in the South of Sweden, which experienced the highest prices in 2021-2022.

  3. 2. The impact of female entrepreneurship on a country’s innovative performance

    Master-uppsats, Göteborgs universitet/Graduate School

    Författare :Laura Lechner; Lina Hartmann; [2023-07-19]
    Nyckelord :female entrepreneurship; innovation performance; country-level analysis; OLS; opportunity-driven entrepreneurship; innovation; developed countries; developing countries;

    Sammanfattning : Purpose – As entrepreneurship is still a traditionally male-dominated field, more research and political initiative is needed to create a level-playing field between women and men in this industry. The purpose of this research, therefore, is to first understand how female entrepreneurship (FE) influences innovation performance (IP) now, and how this effect has changed over time. LÄS MER

  5. 4. Robust Aircraft Positioning using Signals of Opportunity with Direction of Arrival

    Master-uppsats, Linköpings universitet/Reglerteknik

    Författare :Erik Axelsson; Sebastian Fagerstedt; [2023]
    Nyckelord :Simultaneous localisation and mapping; direction of arrival; signals of opportunity; extended Kalman filter; positioning;

    Sammanfattning : This thesis considers the problem of using signals of opportunity (SOO) with known direction of arrival (DOA) for aircraft positioning. SOO is a collective name for a wide range of signals not intended for navigation but which can be intercepted by the radar warning system on an aircraft. LÄS MER
