  1. 6. Itô Diffusions on Level Sets

    Master-uppsats, Uppsala universitet/Analys och partiella differentialekvationer; Uppsala universitet/Statistik, AI och data science

    Författare :Coën Olofsson; [2023]
    Nyckelord :Itô diffusions; level sets; stochastic differential geometry; numerical schemes;

    Sammanfattning : Itô diffusions that move on level sets of functions in Rn, which we have called level processes, are an overlooked variant of the classical Itô processes. These processes find themselves nestled between the study of regular Itô diffusions in Rn and diffusions which are bound to smooth manifolds. LÄS MER

  3. 7. 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. 8. Introducing GA-SSNN: A Method for Optimizing Stochastic Spiking Neural Networks : Scaling the Edge User Allocation Constraint Satisfaction Problem with Enhanced Energy and Time Efficiency

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Nathan Allard; [2023]
    Nyckelord :;

    Sammanfattning : As progress within Von Neumann-based computer architecture is being limited by the physical limits of transistor size, neuromorphic comuting has emerged as a promising area of research. Neuromorphic hardware tends to be substantially more power efficient by imitating the aspects of computations in networks of neurons in the brain. LÄS MER

  5. 9. Stochastic Optimization of Asset Management Project Portfolios: A Risk-Informed Approach

    Master-uppsats, KTH/Matematik (Avd.)

    Författare :Sebastian Persson; Niklas Hansson; [2023]
    Nyckelord :Nuclear asset management; Risk-informed asset management; Portfolio optimization; Project selection; Knapsack problem; Monte Carlo simulation; Conditional Value at Risk; Tillgångsförvaltning; Riskinformerad tillgångsförvaltning; Portföljoptimering; Projekturval; Kappsäcksproblem; Monte Carlo simulering; Conditional Value at Risk;

    Sammanfattning : Asset management within the nuclear industry has become an increasingly relevant topic as safety requirements have tightened and energy security has become more important. Asset management ensures performance and reliability in a nuclear facility by balancing costs, opportunities, and risks to get the most out of assets. LÄS MER

  7. 10. Investigating the Estimation of the infection rate and the fraction of infections leading to death in epidemiological simulation

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Avdelningen för systemteknik

    Författare :Jakob Gölén; [2023]
    Nyckelord :Epidemics; Compartmental Models; Parameter Inference; Synthetic Bootstrap; Infection Rate;

    Sammanfattning : The main goal of this project is to investigate the behaviors of parameters used when modeling an epidemic. A stochastic SIHDRe model is used to simulate how an epidemic evolves over time. LÄS MER
