  1. 1. Topics in optimal design of experiments

    Författare :Sofia Normark; Hans Nyquist; Johan Lyhagen; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; optimal design; factorial experiments; minimax designs; efficiency; locally optimal designs; generalized linear models; binary data; statistik; Statistics;

    Sammanfattning : This thesis contributes to optimal design of experiments in situations where the optimal design depends on unknown parameters. Such situations often occur when the response variable does not have normal distribution, as is the case with many generalized linear models (GLM) and many models for binary response. LÄS MER

  3. 2. Optimal Control of Electrified Powertrains

    Författare :Martin Sivertsson; Lars Eriksson; Giorgio Rizzoni; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Optimal Control; Diesel-Electric; Hybrid Electric Vehicles;

    Sammanfattning : Vehicle powertrain electrification, i.e. combining the internal combustion engine (ICE) with an electric motor (EM), is a potential way of meeting the increased demands for efficient and low emission transportation, at a price of increased powertrain complexity since more degrees of freedom (DoF) have been introduced.

  4. 3. A Probabilistic Approach to Non-Markovian Impulse Control

    Författare :Johan Jönsson; Magnus Perninge; Säid Hamadène; Linnéuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Stochastic optimal control; optimal stopping; optimal switching; impulse control; Snell envelope; obstacle problems; partial differential equation; Matematik; Mathematics;

    Sammanfattning : This thesis treats mathematical considerations that arise in relation to certain stochastic optimal control problems, in particular of switching and impulse type. Both of these problems are extensions of the well-known optimal stopping problem. LÄS MER

  5. 4. Computational Diffusion MRI: Optimal Gradient Encoding Schemes

    Författare :Mohammad Alipoor; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Gradient Encoding Scheme; ADC imaging; Diffusion MRI; D-optimal experiment design; Diffusion Tensor Imaging; Optimal Image acquisition; Second and Fourth Order Tensors.; Diffusion Kurtosis Imaging;

    Sammanfattning : Diffusion-weighted magnetic resonance imaging (dMRI) is a non-invasivestructural imaging technique that provides information about tissue microstructures.Quantitative measures derived from dMRI reflect pathologicaland developmental changes in living tissues such as human brain.

  7. 5. Modeling and Optimal Control of Heavy-Duty Powertrains

    Författare :Vaheed Nezhadali; Lars Eriksson; Giorgio Rizzoni; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Powertrain; transmission system; optimal control; modeling for control;

    Sammanfattning : Heavy duty powertrains are complex systems with components from various domains, different response times during transient operations and different efficient operating ranges. To ensure efficient transient operation of a powertrain, e.g. LÄS MER
