  1. 11. 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. 12. Multiscale & Multiphysics Modelling of Thrust Pad (Air) Bearings

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Nipon Roy; [2023]
    Keywords : Finite element modelling; Air bearing; Multiphysics simulations; Air lubrication; surface texture; Topology optimization;

    Abstract : Without lubrication, machines are not imaginable to perform over a long period of time and complete their designated operations. With its omnipresent availability, the air is capable of functioning as a lubricant in long operations very efficiently. Moreover, thrust bearings support axial loads and transmit power at the same time under heavy loads. READ MORE

  4. 13. Adaptive Model-Based Temperature Monitoring for Electric Powertrains : Investigation and Comparative Analysis of Transfer Learning Approaches

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

    Author : Chenzhou Huang; [2023]
    Keywords : Transfer Learning; Condition Monitoring; Domain Adaptation; Neural Network; Powerstrain.; Siirto-oppiminen; kunnonvalvonta; verkkotunnuksen mukauttaminen; neuroverkko; voimansiirto.; Överföring lärande; tillståndsövervakning; domänanpassning; neuralt nätverk; Powerstrain;

    Abstract : In recent years, deep learning has been widely used in industry to solve many complex problems such as condition monitoring and fault diagnosis. Powertrain condition monitoring is one of the most vital and complicated problems in the automation industry since the condition of the drive affects its health, performance, and reliability.

  5. 14. A Methodology for Evaluating the Performance of Material Models Under Biaxial Loads

    University essay from Lunds universitet/Hållfasthetslära; Lunds universitet/Institutionen för byggvetenskaper

    Author : Emmie Salomonsson; Ina Ögren; [2023]
    Keywords : Material Model; Biaxial Test; Punch Test; Material Test; POM; Simulation; FEA.; Technology and Engineering;

    Abstract : The objective of this thesis is to develop a methodology for evaluating the performance of material models during biaxial loads. This is done by executing identical punch tests, one in a simulation and one in a physical experiment, and then comparing the results from the two. READ MORE

  6. 15. Mitigating Unintended Bias in Toxic Comment Detection using Entropy-based Attention Regularization

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

    Author : Fabio Camerota; [2023]
    Keywords : XLNet; BERT; Toxic Comment Classification; Entropy-based Attention Regularization; XLNet; BERT; Toxisk Kommentar Klassificering; Entropibaserad uppmärksamhetsreglering;

    Abstract : The proliferation of hate speech is a growing challenge for social media platforms, as toxic online comments can have dangerous consequences also in real life. There is a need for tools that can automatically and reliably detect hateful comments, and deep learning models have proven effective in solving this issue. READ MORE
