  1. 11. A Machine Learning Approach for Comprehending Cosmic Expansion

    University essay from KTH/Fysik

    Author : Ludvig Doeser; [2021]
    Keywords : Cosmology; Cosmic expansion; Galaxy Images; Machine learning; Kosmologi; kosmisk expansion; galaxbilder; maskininlärning;

    Abstract : This thesis aims at using novel machine learning techniques to test the dynamics of the Universe via the cosmological redshift-distance test. Currently, one of the most outstanding questions in cosmology is the physical cause of the accelerating cosmic expansion observed with supernovae. READ MORE

  3. 12. Investigation of the Effects of Invisible Neutrino Decay at the Proposed ESSnuSB Experiment

    University essay from KTH/Fysik

    Author : Daniel Kempe; [2021]
    Keywords : Neutrino; Decay; Neutrino oscillations; Neutrino oscillation experiment; Neutrino; Sönderfall; Neutrinooscillationer; Neutrinooscillationsexperiment;

    Abstract : This thesis studies neutrino oscillations at the proposed ESSnuSB experiment and the effects of invisible decay, where the neutrino mass states are assumed to be able to decay, on the planned measurements and the physics potential for this experiment to detect neutrino decays. This is accomplished by simulating a combined scenario of neutrino oscillations and invisible neutrino decay. READ MORE

  4. 13. Toward predictive maintenance in surface treatment processes : A DMAIC case study at Seco Tools

    University essay from Luleå tekniska universitet/Institutionen för ekonomi, teknik, konst och samhälle

    Author : Martin Berg; Albin Eriksson; [2021]
    Keywords : Predictive maintenance; Industry 4.0; Data-driven maintenance; chemical vapour deposition; wet blasting;

    Abstract : Surface treatments are often used in the manufacturing industry to change the surface of a product, including its related properties and functions. The occurrence of degradation and corrosion in surface treatment processes can lead to critical breakdowns over time. READ MORE

  5. 14. Combined CALPHAD and Machine Learning for Property Modelling

    University essay from KTH/Materialvetenskap

    Author : Kyle Paulus; [2020]
    Keywords : ;

    Abstract : Techniques to improve the speed at which materials are researched and developed has been conducted by investigating the machine learning methodology. These techniques offer solutions to connect the length scales of material prop- erties from atomistic and chemical features using materials databases generated from collected data. READ MORE

  6. 15. Analysis of stellar spectra with machine learning

    University essay from Lunds universitet/Astronomi - Genomgår omorganisation; Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation

    Author : Alvaro Segovia Otero; [2020]
    Keywords : Galactic Archaeology; machine learning; chemical abundances; FGK stars; Physics and Astronomy;

    Abstract : Researchers in the field of Galactic Archaeology have entered the era of industrial revolution. Upcoming surveys are planning on observing tens of millions of stars and high precision and accuracy must be ensured when deriving their stellar parameters and elemental abundances. READ MORE
