  1. 1. Numerical Simulations of Metal Recovery for Battery Recycling

    University essay from KTH/Processteknologi

    Author : Morgan Ölander; [2023]
    Keywords : Batteriåtervinning; Metall återvinning; Kristallisation; Computational Fluid Dynamics CFD ; Populationsbalansmodellering; Battery recycling; Metal recovery; Crystallisation; Computational Fluid Dynamics CFD ; Population balance modelling;

    Abstract : Den pågående elektrifieringen av transport och samhälle kräver utveckling av nya metoder för återvinning av batterier. Hydrometallurgi som fokuserar på selektiv kristallisation av metaller är ett intressant alternativ för dessa ändamål. Dessa system kan studeras genom modellering och simulering. READ MORE

  3. 2. Data Trustworthiness Assessment for Traffic Condition Participatory Sensing Scenario

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

    Author : Hairuo Gao; [2022]
    Keywords : Participatory sensing; Data trustworthiness assessment; Anomaly detection; Traffic prediction; Deep neural network; Deltagande avkänning; Bedömning av uppgifternas tillförlitlighet; Upptäckt av anomalier; Trafikprognoser; Djupt neuralt nätverk;

    Abstract : Participatory Sensing (PS) is a common mode of data collection where valuable data is gathered from many contributors, each providing data from the user’s or the device’s surroundings via a mobile device, such as a smartphone. This has the advantage of cost-efficiency and wide-scale data collection. READ MORE

  4. 3. Goodness-of-fit Tests for Time Dependent Ensemble Averages

    University essay from Lunds universitet/Beräkningsbiologi och biologisk fysik - Genomgår omorganisation; Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation

    Author : Jake Lumsden; [2022]
    Keywords : Physics and Astronomy; Mathematics and Statistics;

    Abstract : Fitting a model to a time-dependent ensemble average is a process repeated frequently throughout biophysics. A selected ensemble-averaged observable (⟨y(t)⟩) for a given system can be predicted through the use of an estimated ensemble average, where the estimated ensemble average is created via simulated or experimental data sets.

  5. 4. Conservative Discontinuous Cut Finite Element Methods: Convection-Diffusion Problems in Evolving Bulk-Interface Domains

    University essay from KTH/Matematik (Inst.)

    Author : Sebastian Myrbäck; [2022]
    Keywords : numerical analysis; mathematical modeling; convection-diffusion equation; partial differential equation; unfitted method; CutFEM; finite element method; discontinuous Galerkin method; numerisk analys; matematisk modellering; konvektions-diffusionsekvationer; partiella differentialekvationer; finita elementmetoden; diskontinuerliga Galerkinmetoden;

    Abstract : This work entails studying unfitted finite element discretizations for convection-diffusion equations in domains that evolve in time. In particular, these partial differential equations model the evolution of the concentration of soluble surfactants in bulk-interface domains. READ MORE

  6. 5. Solution of the Stefan problem with general time-dependent boundary conditions using a random walk method

    University essay from

    Author : Daniel Stoor; [2019]
    Keywords : Stefan problem; random walk method; moving boundary; heat transfer;

    Abstract : This work deals with the one-dimensional Stefan problem with a general time- dependent boundary condition at the fixed boundary. The solution will be obtained using a discrete random walk method and the results will be compared qualitatively with analytical- and finite difference method solutions. READ MORE
