  1. 1. Primary Drivers of Sea Level Variability in the North – Baltic Sea Transition Using Machine Learning

    Master-uppsats, Göteborgs universitet/Institutionen för geovetenskaper

    Författare :David Ek; [2023-01-09]
    Nyckelord :;

    Sammanfattning : Global mean sea level is rising, however not uniformly. Regional deviations of sea surface height (SSH) are common due to local drivers, including surface winds, ocean density stratifications, vertical land- & crustal movements and more. LÄS MER

  3. 2. Artificial Neural Network in Exhaust Temperature Modelling : Viability of ANN Usage in Gasoline Engine Modelling

    Master-uppsats, Linköpings universitet/Fordonssystem; Linköpings universitet/Tekniska fakulteten

    Författare :Musa Nibras; Roos Linus; [2022]
    Nyckelord :Artificial Neural Network; Data-driven Modelling; Engine Modelling; Transient behaviour; Static behaviour; Feed Forward Network; Layer Recurrent Network; NARX; Long Short Term Memory; Gated Recurrent Network; Data processing;

    Sammanfattning : Developing and improving upon a good empirical model for an engine can be time-consuming and costly. The goal of this thesis has been to evaluate data-driven modelling, specifically neural networks, to see how well it can handle training for some static models like the mass flow of air into the cylinder, mean effective pressure and pump mean effective pressure but also for transient modelling, specifically the exhaust gas temperature.

  4. 3. Swedish Interest Rate Curve Dynamics Using Artificial Neural Networks

    Master-uppsats, KTH/Matematisk statistik

    Författare :Richard Spånberg; Billy Wallander; [2020]
    Nyckelord :Artificial Neural Network; Yield curve; PCA; Financial Mathematics; Neurala Nätverk; Avkastningskurva; PCA; Finansiell Matematik;

    Sammanfattning : This thesis is a comparative study where the question is whether a neural network approach can outperform the principal component analysis (PCA) approach for predicting changes of interest rate curves. Today PCA is the industry standard model for predicting interest rate curves. LÄS MER

  5. 4. Preoperativ luftvägsbedömning på hund inför orotrakeal intubering

    Kandidat-uppsats, SLU/Dept. of Clinical Sciences

    Författare :Milla Hansson; Iris Wickström; [2019]
    Nyckelord :mallampati; cormack-lehane; luftväg; hund; skallform; intubering; pharynx; larynx; djuromvårdnad;

    Sammanfattning : Orotrakeal intubering är en vanligt förekommande procedur i samband med anestesi. Intubering görs av flera anledningar men framförallt för att upprätthålla fria andningsvägar och effektivt kunna tillföra patienten syrgas. LÄS MER

  7. 5. Consulting with the Citizens : An Introductory Study on Citizen Participation in the European Commission ́s Online Consultations

    Kandidat-uppsats, Uppsala universitet/Statsvetenskapliga institutionen

    Författare :Emil Juslin; [2019]
    Nyckelord :Online Consultations; EU Public Consultations; Citizen Participation; Participation Bias; The EU Consultation Regime;

    Sammanfattning : For a long time the citizen participation in the European Commission Online Consultations have been low and quite insignificant. This came to an abrupt change during 2018, with the consultation on Summertime arrangements bringing out over four million citizens to participate and it is now clear that the citizen impact on consultations are not something to overlook.
