  1. 1. Hidden Markov Models: Identification, Inverse Filtering and Applications

    Författare :Robert Mattila; Bo Wahlberg; Cristian R. Rojas; John Lygeros; Jan H. van Schuppen; Tobias Rydén; Ayca Özcelikkale; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hidden Markov models; HMM; inverse filtering; identification; estimation; method of moments; counter-adversarial autonomous systems; adversarial signal processing; belief estimation; abdominal aortic aneurysm; medical; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : A hidden Markov model (HMM) comprises a state with Markovian dynamics that is hidden in the sense that it can only be observed via a noisy sensor. This thesis considers three themes in relation to HMMs, namely, identification, inverse filtering and applications. LÄS MER

  3. 2. Fire Spalling of Concrete : Theoretical and Experimental Studies

    Författare :Robert Jansson; Johan Silfwerbrand; Ulrich Diedrichs; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Fire spalling of concrete is not a new phenomenon. To some degree there has always been a risk during rapid heating of concrete. Therefore, to a certain degree the effect of fire spalling is included in the bank of data from fire tests and fires on which our understanding of the fire resistance of concrete is based. LÄS MER

  4. 3. Hidden Markov models : Identification, control and inverse filtering

    Författare :Robert Mattila; Bo Wahlberg; Eric Moulines; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hidden markov models; system identification; method of moments; inverse filtering; abdominal aortic aneurysm; medical; markov decision process; structure; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : The hidden Markov model (HMM) is one of the workhorse tools in, for example, statistical signal processing and machine learning. It has found applications in a vast number of fields, ranging all the way from bioscience to speech recognition to modeling of user interactions in social networks. LÄS MER

  5. 4. Human Postures and Movements analysed through Constrained Optimization

    Författare :Robert Pettersson; Anders Eriksson; Elena Gutierrez-Farewik; Hans Berg; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; multibody system; optimal control; trajectory optimization; long jump; posture; Other engineering mechanics; Övrig teknisk mekanik;

    Sammanfattning : Constrained optimization is used to derive human postures and movements. In the first study a static 3D model with 30 muscle groups is used to analyse postures. The activation levels of these muscles are minimized in order to represent the individual's choice of posture. LÄS MER

  7. 5. Company incentives and individual preferences towards sustainable travel alternatives

    Författare :Markus Robèrt; KTH; []
    Nyckelord :;

    Sammanfattning : Since the acceptance of changing travel habits is a matterof subjective preferences and individual values, the questionof how to make individuals voluntarily choose new travelalternatives is not straightforward. In this study we focus onan office district called Nacka Strand outside Stockholm, wherecompanies tried to implement new and more efficientalternatives to personal travel. LÄS MER
