  1. 21. Beyond Mean-Field Description of Bose-Einstein Condensate

    University essay from Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionen

    Author : Daniel Larsson Persson; [2021]
    Keywords : Bose-Einstein condensate; BEC; dilute; non-uniform; quantum depletion; second quantisation; mean field; mean-field approximation; the Gross-Pitaevskii equation; Gross-Pitaevskii; perturbation theory; many-body perturbation theory; Rayleigh-Schrödinger perturbation theory; Rayleigh-Schrödinger; Epstein-Nesbet perturbation theory; Epstein-Nesbet; quantum ring; Physics and Astronomy;

    Abstract : This thesis work is on the theoretical description of dilute Bose-Einstein condensates (BEC) that are non-uniform, meaning that more than one single-particle state is occupied. This phenomenon is usually called quantum depletion. READ MORE

  3. 22. Symbolic Regression using Genetic Programming Leveraging Neural Information Processing

    University essay from Lunds universitet/Matematik LTH

    Author : Nanna Grytzell; [2021]
    Keywords : evolutionary computation; evolutionary algorithm; evolutionary algorithms; genetic algorithm; genetic programming; artificial neural networks; artificial intelligence; machine learning; Mathematics and Statistics; Technology and Engineering;

    Abstract : Regression analysis conducted with traditional mathematical methods can be sub-optimal if the exact model of the observed data is unknown. Evolutionary computing (EC) and deep learning (DL) are viable alternatives, since regression performed with these methods tends to be less dependent on a particular model. READ MORE

  4. 23. Investigating the Learning Behavior of Generative Adversarial Networks

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

    Author : Simon Westberg; [2021]
    Keywords : ;

    Abstract : Since their introduction in 2014, generative adversarial networks (GANs) have quickly become one of the most popular and successful frameworks for training deep generative models. GANs have shown exceptional results on different image generation tasks and they are known for their ability to produce realistic high- resolution images. READ MORE

  5. 24. All-Oxide Ceramic Matrix Composites : Thermal Stability during Tribological Interactions with Superalloys

    University essay from Luleå tekniska universitet/Materialvetenskap

    Author : Daniel Vazquez Calnacasco; [2021]
    Keywords : Ceramic Matrix Composites; All-Oxide Ceramic Matrix Composites OCMC ; Oxide-Oxide Ceramic Matrix Composites Ox-Ox CMC Ox Ox CMC ; Continuous-Fiber Ceramic Composites CFCC ; Long Fiber Composites LFC ; Ceramic Fiber-Matrix Composites CFMC ; Fiber Reinforced Ceramics FRC ; Superalloys; Inconel 718; Tribology; Elevated Temperature; Alumina; Aluminosilicate; Materiales Compuestos de Matriz Cerámica; Compuestos de Matriz Cerámica base Óxido; Superaleaciones; Inconel 718; Tribología; Alta Temperatura; Alumina; Aluminosilicatos;

    Abstract : The challenges faced in today’s industry require materials capable of working in chemically aggressive environments at elevated temperature, which has fueled the development of oxidation resistant materials. All-Oxide Ceramic Matrix Composites (OCMC) are a promising material family due to their inherent chemical stability, moderate mechanical properties, and low weight. READ MORE

  6. 25. The Effect of Ownership on Reimbursement Incentives - Evidence From a 2016 Primary Care Reform in Stockholm County

    University essay from Handelshögskolan i Stockholm/Institutionen för nationalekonomi

    Author : Axel Hellbom Almström; Klara Strömberg; [2021]
    Keywords : ownership; general practice; primary care; reimbursement; Stockholm;

    Abstract : Private care providers play an important role in Swedish healthcare provision, but their place in the Swedish welfare state remains a contentious issue. This study utilizes a difference-in-difference regression model and a 2016 reimbursement reform in Stockholm County to investigate how private ownership affects sensitivity to reimbursement incentive effects among primary care providers.
