  1. 1. Two-Barrier Problems in Applied Probability: Algorithms and Analysis

    University dissertation from Centre for Mathematical Sciences, Lund University

    Author : Mats Pihlsgård; [2005]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Statistics; operations research; programming; actuarial mathematics; Statistik; Matematik; Mathematics; Naturvetenskap; Natural science; Reflection; Stochastic processes; Applied probability; Queueing; operationsanalys; programmering; aktuariematematik;

    Abstract : This thesis consists of five papers (A-E). In Paper A, we study transient properties of the queue length process in various queueing settings. We focus on computing the mean and the Laplace transform of the time required for the queue length starting at $x0. We define the loss rate due to the reflection. READ MORE

    Abstract : The main objective in sampling is to select a sample from a population in order to estimate some unknown population parameter, usually a total or a mean of some interesting variable. When the units in the population do not have the same probability of being included in a sample, it is called unequal probability sampling. READ MORE

  3. 3. Analysis and Modelling of Mineral and Element Composition in Compression Breakage

    University dissertation from Gothenburg : Chalmers tekniska högskola

    Author : Lorena Guldris Leon; [2018]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; minerals; rare metals; elements; cone crusher; modelling; compressive crushing;

    Abstract : The outstanding properties of tungsten and tantalum make them valuable metals and, in some cases, irreplaceable in applications. The growing interest due to the high economic importance and the limited supply places these metals in the critical metals risk list. READ MORE

  4. 4. System identification of large-scale linear and nonlinear structural dynamicmodels

    University dissertation from Gothenburg : Chalmers tekniska högskola

    Author : Vahid Yaghoubi Nasrabadi; [2016]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Finite element model; Surrogate modeling; Bootstrapping; Polynomial chaos expansion; System identification; Exponential integration; Uncertainty quantification;

    Abstract : System identification is a powerful technique to build a model from measurement data by using methods from different fields such as stochastic inference, optimization and linear algebra. It consists of three steps: collecting data, constructing a mathematical model and estimating its parameters. READ MORE

  5. 5. Markov Chains, Renewal, Branching and Coalescent Processes Four Topics in Probability Theory

    University dissertation from Stockholm : Matematiska institutionen

    Author : Andreas Nordvall Lagerås; Thomas Höglund; Ingemar Kaj; [2007]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; MATHEMATICS Applied mathematics Mathematical statistics; MATEMATIK Tillämpad matematik Matematisk statistik; matematisk statistik; Mathematical Statistics;

    Abstract : This thesis consists of four papers.In paper 1, we prove central limit theorems for Markov chains under (local) contraction conditions. As a corollary we obtain a central limit theorem for Markov chains associated with iterated function systems with contractive maps and place-dependent Dini-continuous probabilities. READ MORE
