  1. 1. Dirichlet-to-Neumann maps and Nonlinear eigenvalue problems

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Tindra Jernström; Anna Öhman; [2023]
    Keywords : Dirichlet-to-Neumann maps; Nonlinear eigenvalue problems; Absorbing boundary conditions;

    Abstract : Differential equations arise frequently in modeling of physical systems, often resulting in linear eigenvalue problems. However, when dealing with large physical domains, solving such problems can be computationally expensive. READ MORE

  3. 2. Parameter Update Schemes for Hidden Markov Models applied to Financial Returns

    University essay from Lunds universitet/Matematisk statistik

    Author : Sigfrid Forsberg; [2022]
    Keywords : Markov Chain; Finance; Hidden Markov Model; Generalized Autoregressive Score Model; S P-500; Nikkei; Adaptive Model; Volatility; Regime-switching Model; Line-Search Algorithm; Predictor-Corrector; Quasi-Newton; Mathematics and Statistics;

    Abstract : This thesis was dedicated to investigating the use of different parameter update schemes for Hidden Markov models with time-varying parameters, with an emphasis on developing alternatives to the quasi-Newton step. The focus was on applications to financial returns, using data from the S\&P-500 and the Nikkei index, and for comparison, a trial using synthetic data was also performed. READ MORE

    Abstract : Today’s society is facing a large increase of automation and smart devices. Everything from coffee machines to fridges include some kind of electronics and embedded systems. The focus of this Bachelor’s thesis was to dive deeper into how these automated devices can be controlled and more specifically a robot arm. READ MORE

  6. 5. Comparing Different Approaches for Solving Large Scale Power Flow Problems on the CPU and GPU with the Newton-Raphson Method

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

    Author : Manolo D'Orto; [2020]
    Keywords : ;

    Abstract : Power system modelling is increasing in importance. It is vital for power system operations and transmission grid expansions, and therefore the future energy transition. The Swedish power system is under fast development to face the progress of more flexible demand, a higher share of distributed renewable sources, and updated capacities. READ MORE
