  1. 21. Modelling and forecasting economic time series with single hidden-layer feedforward autoregressive artificial neural networks

    Författare :Gianluigi Rech; Handelshögskolan i Stockholm; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : This dissertation consists of 3 essays In the first essay, A Simple Variable Selection Technique for Nonlinear Models, written in cooperation with Timo Teräsvirta and Rolf Tschernig, I propose a variable selection method based on a polynomial expansion of the unknown regression function and an appropriate model selection criterion. The hypothesis of linearity is tested by a Lagrange multiplier test based on this polynomial expansion. LÄS MER

  3. 22. Linking Probability Theory and Quantum Mechanics, and a Novel Formulation of Quantization

    Författare :Fritiof Wallentin; Andrei Khrennikov; Kisil Vladimir; Linnéuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; quantum mechanics; contextuality; probabilistic interpretation; Born’s rule; frequentist interpretation; unitary representations; classical statistical mechanics; Koopman-von Neumann formulation; hidden-variable model; quantization.; Matematik; Mathematics;

    Sammanfattning : This doctoral thesis in mathematics consists of three articles that explore the probabilistic structure of quantum mechanics and quantization from a novel perspective.The thesis adopts a probabilistic interpretation of quantum mechanics, which views the archetypical quantum experiments of Bell- and double-slit- type as violating the principle of non-contextuality, i.

  4. 23. Intention recognition in human machine collaborative systems

    Författare :Daniel Aarno; Danica Kragic; Darius Burschka; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Robotics; Human-machine collaboration; Virtual fixture; hidden Markov model; Machine learning; Artificial intelligence; Computer science; Datavetenskap;

    Sammanfattning : Robotsystem har använts flitigt under de senaste årtiondena för att skapa automationslösningar i ett flertal områden. De flesta nuvarande automationslösningarna är begränsade av att uppgifterna de kan lösa måste vara repetitiva och förutsägbara. LÄS MER

  5. 24. Cultivating educational research in Lao PDR : For a better future?

    Författare :Keophouthong Bounyasone; Ngouay Keosada; Lars Dahlström; Ann-Louise Silfver; Gustave Callewaert; Umeå universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; action research; teacher education; globalisation; technical rationality; hidden policy ensembles; policy backlashes; context; Lao PDR; Education; Pedagogik; pedagogik; Education;

    Sammanfattning : This thesis looks at the introduction of educational action research as part of the national education reforms in Lao PDR. National policies on education emphasise concepts such as ‘education for all’ and ‘student-centred education’ taken from the globalised education reform agenda. LÄS MER

  7. 25. Rainflow Analysis of Switching Markov Loads

    Författare :Pär Johannesson; Matematisk statistik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; actuarial mathematics; programming; operations research; Statistics; rainflow matrix; fatigue; vehicle load; hidden Markov model; random load; Markov model; Switching process; Statistik; operationsanalys; programmering; aktuariematematik;

    Sammanfattning : Rainflow cycles are often used in fatigue analysis of materials for describing the variability of applied loads. Therefore, an important characteristic of a random load process is the intensity of rainflow cycles, also called the expected rainflow matrix (RFM), which can be used for evaluation of the fatigue life.
