  1. 1. A theoretical framework for interpretation and prediction of magneto-optical measurements

    University essay from Uppsala universitet/Materialteori

    Author : Viktor Frilén; [2023]
    Keywords : moke; tmoke; lmoke; pmoke; magneto-optical effects; layered media; dielectric function; maxwells equations; dielectric tensor; linear respons; magnetism; light induced transistions; DFT; SO;

    Abstract : The interplay of experiments and theory is essential to deepen our understanding of magnetization dynamics. This thesis aims to serve as a bridge between these two aspects by establishing a mathematical framework that enables the computation of optical observable quantities based on theoretical models.

  3. 2. Air quality prediction in metropolitan areas using deep learning methods

    University essay from Stockholms universitet/Institutionen för data- och systemvetenskap

    Author : Augustin Ionut Ionascu; [2023]
    Keywords : air quality; forecasting; time-series; univariate; multivariate; multi-step; Attention; Transformer;

    Abstract : The rapid growth of the world's urban population shows that people are increasingly moving to cities. In recent decades, the frequent occurrence of smog caused by increasing industrialization has brought environmental pollution to record highs. READ MORE

  4. 3. Development of a model for ionospheric instabilities in the equatorial region

    University essay from Luleå tekniska universitet/Rymdteknik

    Author : Thea Lepage; [2023]
    Keywords : ;

    Abstract : This work is part of a bigger project on analyzing the ionospheric dynamics in the equatorial region using simulations. The main objective of this study is to determine and characterize the parameters needed to trigger instabilities and thus the formation of plasma bubbles. READ MORE

  5. 4. Rotor temperature estimation in Induction Motors with Supervised Machine Learning

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Christopher Gauffin; [2023]
    Keywords : Induction motors; Supervised Machine learning; Power converters; Parameter estimation; Embedded systems; Induktionsmotorer; Övervakad maskininlärning; Strömkonverterare; Parameterestimering; Inbyggda system;

    Abstract : The electrification of the automotive industry and artificial intelligence are both growing rapidly and can be greatly beneficial for a more sustainable future when combined. Induction machines exhibit many complex relationships between physical and electromagnetic properties that must be calculated in order to produce the correct quantities of torque and speed commanded by the driver.

  6. 5. Integrability of super spin chains in 6D N=(1,0) SCFTs

    University essay from Uppsala universitet/Teoretisk fysik

    Author : Zuxian He; [2023]
    Keywords : 6D SCFTs; integrability; spin chains; representation theory; symmetry; oscillators; Lie algebra;

    Abstract : Superconformal field theories (SCFTs) are an important class of quantum field theories. These SCFTs have been a significant component in exploring and comprehending the fundamental framework of quantum field theories. READ MORE
