  3. 2. Forecasting the OMXS30 - a comparison between ARIMA and LSTM

    Kandidat-uppsats, Uppsala universitet/Statistiska institutionen

    Författare :David Andréasson; Jesper Mortensen Blomquist; [2020]
    Nyckelord :machine learning; deep learning; neural networks; RNN; time series; stock market; index;

    Sammanfattning : Machine learning is a rapidly growing field with more and more applications being proposed every year, including but not limited to the financial sector. In this thesis, historical adjusted closing prices from the OMXS30 index are used to forecast the corresponding future values using two different approaches; one using an ARIMA model and the other using an LSTM neural network.

  4. 3. "Vem bryr sig?" - om fyra förskollärares perspektiv på, och arbete med, barns andlighet

    Uppsats för yrkesexamina på grundnivå, Malmö universitet/Fakulteten för lärande och samhälle (LS)

    Författare :Jesper Blomquist; [2019]
    Nyckelord :spirituality; children; educators; preschool; strategies;

    Sammanfattning : The aim of this qualitative study is to investigate how educators in preschools with denominational components reflect upon, and work with children’s spirituality. In order to meet this aim, two research questions were posed concerning educators’ approach to, and teaching strategies of, children’s spirituality, and semi–structured interviews were conducted with four educators employed by preschools with denominational components.

  5. 4. Online Identification of Running Resistance and Available Adhesion of Trains

    Master-uppsats, Fordonssystem

    Författare :Jesper Ahlberg; Esbjörn Blomquist; [2011]
    Nyckelord :running resistance; extended kalman filter; ekf; parameter estimation; acceleration estimation; adaptive models; adhesion; freight trains; numerical differentiation; gångmotstånd; extended kalman filter; ekf; parameterskattning; accelerationsskattning; adaptiva modeller; adhesion; godståg; numerisk derivering;

    Sammanfattning : Two important physical aspects that determine the performance of a running train are the total running resistance that acts on the whole train moving forward, and the available adhesion (utilizable wheel-rail-friction) for propulsion and breaking. Using the measured and available signals, online identification of the current running resistance and available adhesion and also prediction of future values for a distance ahead of the train, is desired.
