  1. 1. Numerical Simulations of Resonant Tunnelling Diodes

    Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)

    Författare :Love Sundström; Alexander Holmström Janeld; [2023]
    Nyckelord :Quantum mechanics; numerical methods; resonant tunnelling diode;

    Sammanfattning : In this thesis, four different numerical techniques are implemented for the purpose of simulating resonant tunnelling diodes (RTDs). The chosen methods were: piecewise constant transfer matrix (TMM-C), piecewise linear transfer matrix (TMM-L), quantum transmitting boundary method (QTBM), and the Crank-Nicolson method (CN).

  3. 2. Misfire Detection in Heavy Duty Diesel Engines Using Knock Sensors

    Master-uppsats, Linköpings universitet/Fordonssystem

    Författare :Carl Sjöstedt; [2023]
    Nyckelord :ICE; combustion engine; combustion engines; Scania; diesel; knock; knock sensor; knock sensors; misfire; misfire detection;

    Sammanfattning : In this thesis the possibility of using knock sensors for misfire detection in heavy duty diesel engines is investigated. This is of great interest due to many emission legislations getting stricter, especially in the US where robust misfire detection is mandatory for these types of engines. LÄS MER

  4. 3. Merton's Portfolio Problem under Jourdain--Sbai Model

    Master-uppsats, Mälardalens universitet/Akademin för utbildning, kultur och kommunikation

    Författare :Sajedeh Saadat; [2023]
    Nyckelord :Merton’s Optimal Investment-Consumption Problem; Dynamic Programming; Hamilton-Jacobi-Bellman equation; Stochastic Volatility Model; Finite-difference method; Crank-Nicolson.;

    Sammanfattning : Portfolio selection has always been a fundamental challenge in the field of finance and captured the attention of researchers in the financial area. Merton's portfolio problem is an optimization problem in finance and aims to maximize an investor's portfolio. LÄS MER

  5. 4. Spatial Statistical Modelling of Insurance Claim Frequency

    Master-uppsats, Lunds universitet/Matematisk statistik

    Författare :Daniel Faller; [2022]
    Nyckelord :Insurance risk; claim frequency; Markov chain Monte Carlo MCMC ; Riemann manifold Metropolis adjusted Langevin algorithm MMALA ; spatial statistics; Gaussian Markov random field GMRF ; preconditioned Crank Nicolson Langevin algorithm pCNL ; Gibbs sampling; Bayesian hierarchical modelling; high dimensional; shrinkage prior; horseshoe prior; regularisation.; Mathematics and Statistics;

    Sammanfattning : In this thesis a fully Bayesian hierarchical model that estimates the number of aggregated insurance claims per year for non-life insurances is constructed using Markov chain Monte Carlo based inference with Riemannian Langevin diffusion. Some versions of the model incorporate a spatial effect, viewed as the relative spatial insurance risk that originates from a policyholder's geographical location and where the relative spatial insurance risk is modelled as a continuous spatial field.

  7. 5. Generate power, generate art : Experiments with human-powered art, electronic paper and creative coding

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

    Författare :Roni Kaufman; [2022]
    Nyckelord :Human-computer interaction; Interaction design; Sustainable interaction; Interactive Arts; Media Arts; Människa–datorinteraktion; Hållbar interaktion; Interaktiv konst; Mediekonst;

    Sammanfattning : This is a multidisciplinary project, at the intersection between interaction design, software development and media art. Human-Powered Interactions (HPI) is a field of Human-Computer Interactions (HCI) interested in self-sustainable systems in which power generation and the user interaction are simultaneous, unlike, for example, dynamo torches which have rechargeable batteries.
