  1. 1. Analysing Regime-Switching and Cointegration with Hamiltonian Monte Carlo

    Master-uppsats, Uppsala universitet/Statistiska institutionen

    Författare :Jakob Brandt; [2023]
    Nyckelord :Time Series Econometrics; Regime-Switching; Cointegration; Markov Chain Monte Carlo; Hamiltonian Monte Carlo;

    Sammanfattning : The statistical analysis of cointegration is crucial for inferring shared stochastic trends between variables and is an important area of Econometrics for analyzing long-term equilibriums in the economy. Bayesian inference of cointegration involves the identification of cointegrating vectors that are determined up to arbitrary linear combinations, for which the Gibbs sampler is often used to simulate draws from the posterior distribution.

  3. 2. The influence of particle size distribution on bio-coal gasification rate as related to packed beds of particles

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Markus Bäckebo; [2020]
    Nyckelord :Bio-coal; Particle size distributions; Reaction rate; Gasification;

    Sammanfattning : This thesis is a part of a collaboration between Höganäs AB and Luleå University of Technology, aiming at replacing fossil process coal with bio-coal in their sponge iron process. The difference in gasification reactivity, i.e. LÄS MER

  4. 3. Selektiva distributionssystem - En studie av konkurrenslagen och dess tillämpning

    Kandidat-uppsats, Lunds universitet/Juridiska institutionen; Lunds universitet/Juridiska fakulteten

    Författare :Sara Aspelin; [2017]
    Nyckelord :Konkurrensrätt; Law and Political Science;

    Sammanfattning : Selektiva distributionssystem är marknadsföringsmetod som ofta används vid distribution av exklusiva och tekniskt avancerade varor. Denna typ av distribution innebär att produkter som säljs inom systemet endast distribueras av återförsäljare som är auktoriserade. LÄS MER

  5. 4. Modeling of Electromagnetic Heating of Multi-coil Inductors in Railway Traction Systems

    Master-uppsats, Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Författare :IMAN BAKTASH; [2015]
    Nyckelord :;

    Sammanfattning : Inductors are frequently used in railway electrical tractions systems in filtering and current limiting operations. Magnetic fields are generated due to the flow of large AC currents through the coils, which intend induce currents on the coils as well as the metallic components in the vicinity, causing electromagnetic heating.

  7. 5. Carbon Capture and Storage : Energy penalties and their impact on global coal consumption

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Naturresurser och hållbar utveckling

    Författare :Anders Thorbjörnsson; [2014]
    Nyckelord :CCS; energy penalty; efficiency; coal consumption; Peak coal; energy supply scenarios;

    Sammanfattning : Coal has been used as a fuel for electricity generation for centuries. Inexpensive electricity from coal has been a key component in building large industrial economies such as USA and China. But in recent decades the negative aspects of coal, mainly carbon dioxide emissions, has changed the view on the fuel. LÄS MER
