  1. 1. Price policy estimation for Demand Response of heat-pump-based loads

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Carlos Eduardo Gil Simancas; [2023]
    Nyckelord :Differential Evolution; Electricity Grids; Flexibility Services; Heat-pumps; Heterogeneous Loads; Implicit Demand Response; Optimization; Differentiell utveckling; elnät; flexibilitetstjänster; heterogena belastningar; implicit efterfrågesvar; optimering; värmepump;

    Sammanfattning : The electricity grids have become a key player in the society. An increased usage of electricity is both a result from the more electrified society, but also as a main solver in reaching the climate goals by reducing emissions. LÄS MER

  3. 2. Following the trend? : Using a time series momentum strategy on the Swedish stock market

    Kandidat-uppsats, Umeå universitet/Nationalekonomi

    Författare :Markus Haglund; [2023]
    Nyckelord :;

    Sammanfattning : The momentum strategy can be divided into two different sections where this study has focused on a time series momentum strategy where assets that in the previous period will continue in the same trend the following period. This theory stands in opposition to the efficient market hypothesis which in its weakest market form says that all previous market data is already incorporated in the price the asset is selling for today, and by that, it cannot be used to make abnormal profits.

  4. 3. Utvärdering av kvaliteten för två UAV/LiDAR-system i olika prisklasser : Jämförelse av osäkerheten vid skapandet av digitala terrängmodeller

    Uppsats för yrkesexamina på grundnivå, Högskolan i Gävle/Samhällsbyggnad

    Författare :Aksén Fredrik; [2023]
    Nyckelord :UAV; LiDAR; DTM; laser scanning; uncertainty; UAV; LiDAR; DTM; laserskanning; osäkerhet;

    Sammanfattning : UAV/LiDAR-system har utvecklats snabbt under de senaste åren. De har blivit kompaktare och kan generera en hög punkttäthet med låg mätosäkerhet. Samtidigt har prisnivåerna sjunkit, vilket medfört att ett UAV/LiDAR-system nu kan införskaffas för några hundra tusen kronor. LÄS MER

  5. 4. An Investigation and Comparison of Machine Learning Methods for Selecting Stressed Value-at-Risk Scenarios

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Avdelningen för systemteknik

    Författare :Moa Tennberg; [2023]
    Nyckelord :Value-at-Risk; Total margin; Procyclicality; Machine learning; Binary classification; Supervised learning; Unsupervised learning; Random forest; Multilayer perceptron;

    Sammanfattning : Stressed Value-at-Risk (VaR) is a statistic used to measure an entity's exposure to market risk by evaluating possible extreme portfolio losses. Stressed VaR scenarios can be used as a metric to describe the state of the financial market and can be used to detect and counter procyclicality by allowing central clearing counterparities (CCP) to increase margin requirements.

  7. 5. House Price and Fertility Decisions: Evidence from Taiwan

    Master-uppsats, Göteborgs universitet/Graduate School

    Författare :Samuel Attafuah; Ko-Cheng Chang; [2022-06-23]
    Nyckelord :House Price; Fertility; Taiwan; Realized Fertility RF ; Fertility Intentions LF ; Fertility Gap FG ;

    Sammanfattning : Given the concurrent incidence of falling birth rates and increasing house prices experienced in Taiwan over the past two decades, the current thesis examines the role of house prices on fertility-related behaviors and outcomes among Taiwanese households. Acknowledging that housing is a major cost associated with childrearing and the theoretical assumption that children are normal goods, we hypothesize that house price inflation will adversely impact fertility and that current non-homeowners are the most affected due to the “resource exhaustion effect”.
