  2. 1. Applications of artificial neural networks for time series data analysis in energy domain

    Author : Fan Zhang; Hasan Fleyeh; Stawomir Nowaczyk; Högskolan Dalarna; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Deregulated energy market; electricity prices; district heating; energy efficiency; neural networks; Complex Systems – Microdata Analysis; Komplexa system - mikrodataanalys;

    Abstract : With the development of artificial intelligence techniques and increased installation of smart meters in recent years, time series analysis using historical data in the energy domain becomes applicable. In this thesis, microdata analysis approaches are used, which consist of data acquisition, data processing, data analysis and data modelling, aiming to address two research problems in the energy domain.

  4. 2. Improved building energy simulations and verifications by regression

    Author : Jimmy Vesterberg; Thomas Olofsson; Folke Björk; Umeå universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Calibrated simulations; Energy signature; Regression; BES; IDA ICE; Multifamily buildings; EUI;

    Abstract : It is common with significant differences between calculated and actual energy use in the building sector. These calculations are often performed with whole building energy simulation (BES) programs. In this process the analyst must make several assumptions about the studied building and its users.

  6. 4. Delving in the Dark : Searching for Signatures of Non-Standard Physics in Cosmological and Astrophysical Observables

    Author : Janina J. Renk; Joakim Edsjö; Pat Scott; Felix Kahlhöfer; David F. Mota; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; cosmology; gravitation; Galileon; dark energy; dark matter; cosmic superstrings; neutrino mass; parameter inference; teoretisk fysik; Theoretical Physics;

    Abstract : The dark sectors of our Universe, dark matter and dark energy, together constitute about 96 % of the total energy content of the Universe. To date, we only have observational evidence for their existence. READ MORE

  7. 5. Solar Forcing of Nitric Oxide in the Upper Atmosphere

    Author : Koen Hendrickx; Linda Megner; Jörg Gumbel; Bernd Funke; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; nitric oxide; NO; mesosphere; lower thermosphere; MLT; energetic particle precipitation; EPP; medium energy electrons; MEE; SOFIE; SNOE; WACCM; POES; atmosfärvetenskap och oceanografi; Atmospheric Sciences and Oceanography;

    Abstract : The forcing of the Sun on Earth's atmosphere manifests itself via solar radiation and energetic particle precipitation (EPP), which variations are most noticeable in the upper regions of the atmosphere. A key species in the lower thermosphere, which is influenced by solar forcing, is nitric oxide (NO). READ MORE
