  1. 1. Evaluation of a stochastic model of coherent turbulent structures for atmospheric particle deposition applications

    University essay from Uppsala universitet/Luft-, vatten- och landskapslära

    Author : Andreas Eriksson; [2022]
    Keywords : atmospheric dispersion; particle deposition; k-epsilon; RANS; lagrangian particle model; stochastic particle model; OpenFOAM; SIMPLE algorithm; ABL; atmospheric boundary layer; neutral boundary layer; coherent turbulent structures;

    Abstract : In this thesis, we have evaluated a stochastic Lagrangian model for computing particle deposition rates with prospects to use for atmospheric deposition applications.  The model is one-dimensional and models the particle dynamics in the boundary layers near walls and obstacles by simulating the coherent turbulent structures and Brownian motion governing the wall-normal transport.

  3. 2. Noisy recognition of perceptual mid-level features in music

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

    Author : Simon Mossmyr; [2021]
    Keywords : ;

    Abstract : Self-training with noisy student is a consistency-based semi-supervised self- training method that achieved state-of-the-art accuracy on ImageNet image classification upon its release. It makes use of data noise and model noise when fitting a model to both labelled data and a large amount of artificially labelled data. READ MORE

  4. 3. A Stochastic Analysis Framework for Real-Time Systems under Preemptive Priority-Driven Scheduling

    University essay from Akademin för innovation, design och teknik

    Author : Muhammad Azhar; [2011]
    Keywords : Stochastic Analysis; Stochastic Execution Time; Stochastic Release Time; Stochastic WCET; Stochastic WCRT; Steady State Backlog; Shrink Operation; Convolve From Operation; Probability of a Task Meeting its Deadline; Probability of a Task Missing its Deadline; Probability of a Job Meeting its Deadline; Probability of a Job Missing its Deadline; Stochastic System Utilization Factor; Deadline Miss to Meet Ratio.;

    Abstract : This thesis work describes how to apply the stochastic analysis framework, presented in [1] for general priority-driven periodic real-time systems. The proposed framework is applicable to compute the response time distribution, the worst-case response time, and the deadline miss probability of the task under analysis in the fixed-priority driven scheduling system.
