  1. 11. Hur har Ukrainas export till EU-länder påverkats av inträdet i ett frihandelsområde?

    Kandidat-uppsats, Lunds universitet/Nationalekonomiska institutionen

    Författare :Moa Johansson Rittemar; [2023]
    Nyckelord :Ukraina; Europeiska unionen; DCFTA; bilateral handel; gravitationsmodellen; Business and Economics;

    Sammanfattning : By supporting the economy of Ukraine, the Association Agreement between the EU and Ukraine is thought to have played an important role in EU’s support during recent crises. The agreement was signed in 2014 and included a deep and comprehensive free trade area (DCFTA). LÄS MER

  3. 12. Improved Statistical Methods for Elliptic Stochastic Homogenization Problems : Application of Multi Level- and Multi Index Monte Carlo on Elliptic Stochastic Homogenization Problems

    Kandidat-uppsats, Uppsala universitet/Tillämpad beräkningsvetenskap

    Författare :Khalil Daloul; [2023]
    Nyckelord :Homogenization; Multilevel Monte Carlo; Multi-Index Monte Carlo; Monte Carlo; Multiscale methods;

    Sammanfattning : In numerical multiscale methods, one relies on a coupling between macroscopic model and a microscopic model. The macroscopic model does not include the microscopic properties that the microscopic model offers and that are vital for the desired solution. LÄS MER

  4. 13. A high-order artificial viscosity finite element method for the Vlasov-Poisson system

    Master-uppsats, Uppsala universitet/Institutionen för informationsteknologi

    Författare :Junjie Wen; [2023]
    Nyckelord :;

    Sammanfattning : We introduce a finite element method with high-order accuracy for approximating the Vlasov-Poisson system. This method uses continuous Lagrange polynomials as basis functions and employs explicit Runge-Kutta schemes for time discretization. A residual-based artificial viscosity technique is applied for stabilization. LÄS MER

  5. 14. Pricing and Modeling Heavy Tailed Reinsurance Treaties - A Pricing Application to Risk XL Contracts

    Master-uppsats, KTH/Matematisk statistik

    Författare :Ormia Abdullah Mohamad; Anna Westin; [2023]
    Nyckelord :Reinsurance; Extreme Value Theory; POT-model; Hill estimator; Risk XL contracts; Generalized Pareto distribution; Method of Moments.; Återförsäkring; Extremevärdesteori; POT-modellen; Hill estimatorn; Risk XL kontrakt; generella Paretofördelningen; Momentmetoden.;

    Sammanfattning : To estimate the risk of a loss occurring for insurance takers is a difficult task in the insurance industry. It is an even more difficult task to price the risk for reinsurance companies which insures the primary insurers. LÄS MER

  7. 15. Application of Physics-Informed Neural Networks for Galaxy Dynamics

    Master-uppsats, Linnéuniversitetet/Institutionen för fysik och elektroteknik (IFE)

    Författare :Lucas Barbier; [2023]
    Nyckelord :;

    Sammanfattning : Developing efficient and accurate numerical methods to simulate dynamics of physical systems has been an everlasting challenge in computational physics. Physics-Informed Neural Networks (PINNs) are neural networks that encode laws of physics into their structure. LÄS MER
