  1. 1. Risk-Averse Multi-Armed Bandit Problem with Multiple Plays

    University essay from Göteborgs universitet/Institutionen för data- och informationsteknik

    Author : Siri Dahlgren; Nicholas Marriott; [2023-10-23]
    Keywords : MAB; Gittins; Markovian bandit; risk-aversion; policy iteration; multiple plays;

    Abstract : This study aims to construct an efficient heuristic, referred to as RA, for a riskaverse Markovian multi-armed bandit problem (MAB) with multiple plays. The RA incorporates risk-aversion and multiple plays by modifying the Gittins index strategy. READ MORE

  3. 2. Admissibility and Ap classes for radial weights in Rn

    University essay from Linköpings universitet/Analys och didaktik; Linköpings universitet/Tekniska fakulteten

    Author : Simon Bladh; [2023]
    Keywords : Doubling measure; exponent sets; p-admissible weight; Ap-weight; p-Poincaré- inequality; radial weight;

    Abstract : In this thesis we study radial weights on Rn. We study two radial weights with different exponent sets. We show that they are both 1-admissible by utilizing a previously shown sufficient condition, for radial weights to be 1-admissible, together with some results connecting exponent sets and Ap weights.

  4. 3. Itô Diffusions on Level Sets

    University essay from Uppsala universitet/Analys och partiella differentialekvationer; Uppsala universitet/Statistik, AI och data science

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

    Abstract : 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. READ MORE

  5. 4. Enhancing Servo System Performance : Robust Nonlinear Deadbeat Predictive Current Control for Permanent Magnet Synchronous Motors

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

    Author : Xingyu Zhao; [2023]
    Keywords : keywords here: Deadbeat Predictive Current Control; Permanent Magnet Synchronous Motor; Flux Linkage Nonlinearity; Parameter Inaccuracies; Nonlinear Feedforward Compensation; Delayed Integral Action.; Deadbeat-prediktiv strömreglerin; Permanenta magnet-synkronmotorn; Ickelinjäriteter i flödeslänkningen; Felaktigheter i parametrar; Icke-linjär framåtmatningskompensation; Fördröjd integralåtgärd.;

    Abstract : The Permanent Magnet Synchronous Motor (PMSM, also known as the servo motor) is a crucial component within robotic servo systems. To optimally respond to the torque demands sent from the high-level motion controller, the PMSM current controller must track the reference with speed and precision. READ MORE

  6. 5. Computational Fluid Dynamics of the flow in a diffuser : - like geometry

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Rasmus Johansson Oskarsson; [2023]
    Keywords : Fluid mechanics; Flow simulation; RANS; Flow separation; Diffuser;

    Abstract : Simulations were performed to investigate flow separation of an asymmetricdiffuser - like geometry. The geometry used for the simulations was modeledafter an experimental setup with recorded flow data, which was compared tothe simulated data. For all simulations, steady state flow at the inlet was usedwith the assumption of a 2D flow. READ MORE
