  1. 1. Symmetry Analysis of Orbitals in a Plane Wave Basis : A Study on Molecules and Defects in Solids

    University essay from Linköpings universitet/Teoretisk Fysik

    Author : William Stenlund; [2022]
    Keywords : Point Defect; Divacancy; Symmetry; Group Theory; DFT; Plane Wave; Plane Wave Basis; 4H-SiC;

    Abstract : Modeling and analysing materials with theoretical tools is of great use when finding new systems for applications, for example, semiconductors with point defects can be used for quantum applications, like single photon emitters. One important aspect to consider symmetry, which can yield useful information about the properties of a system. READ MORE

  3. 2. Evaluation of Convolutional Neural Networks for Image Quality Classification based on Synthetic Data

    University essay from Lunds universitet/Matematik LTH

    Author : Vendela Nigård; Joar Karlgren Gustavsson; [2022]
    Keywords : Convolutional neural networks; Machine learning; transfer learning; image quality assessment; camera production; image analysis; Mathematics and Statistics;

    Abstract : In camera production the image quality is of utter importance. Several tests during the production ensure this high quality. In this thesis the possibility of creating a final test, that classifies the image quality with the help of machine learning, specifically convolutional neural networks, was investigated. READ MORE

  4. 3. Influence of strain and point defects on the Seebeck coefficient of thermoelectric CoSb3 : Inverkan av töjnings och punktdefekter på Seebeck-koefficienten för termoelektrisk CoSb3

    University essay from Malmö universitet/Fakulteten för teknik och samhälle (TS)

    Keywords : Cobalt antimonide; Thermoelectric; Strain; Seebeck coefficient; oxidation; DFT; DFT-MD;

    Abstract : Many studies and experiments have been conducted over the years to find solutions to the electricity problem. This issue is not just related to how fossil fuels are dispensed. Also, the environmental concerns associated with using fossil fuels have become a severe issue, which is a major cause of environmental pollution and ozone layer damage. READ MORE

  5. 4. Investigation of surface scratches created during strip steel manufacturing

    University essay from

    Author : Kalaivanan Raju; [2019]
    Keywords : ;

    Abstract : Thin flapper valves are made from a stainless steel strip that contains 13.5 wt. % Chromium.  Sometimes in its processing this strip experiences a surface defect which may affect the end product performance negatively, so they are not desirable. READ MORE
