    Keywords : 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;

    Abstract : 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. READ MORE

  5. 18. Numerical methods for inverse heat conduction problems

    Author : Fredrik Berntsson; Per Christian Hansen; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Ill-posed; Heat Conduction; Regularization; MATHEMATICS; MATEMATIK;

    Abstract : In many industrial applications one wishes to determine the temperature history on the surface of a body, where the surface itself is inaccessible for measurements. The sideways heat equation is a model of this situation. READ MORE

  6. 19. Topics in geometry, analysis and inverse problems

    Author : Hans Rullgård; Mikael Passare; Victor Palamodov; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Laurent series; Harnack curves; differential equations; tomography; Mathematical logic; Matematisk logik;

    Abstract : The thesis consists of three independent parts.Part I: Polynomial amoebasWe study the amoeba of a polynomial, as de ned by Gelfand, Kapranov and Zelevinsky. A central role in the treatment is played by a certain convex function which is linear in each complement component of the amoeba, which we call the Ronkin function. READ MORE

  7. 20. Efficient Adaptive Algorithms for an Electromagnetic Coefficient Inverse Problem

    Author : John Bondestam Malmberg; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; coefficient inverse problem; inverse scattering; Maxwell’s equations; approximate global convergence; finite element method; adaptivity; ; a posteriori error analysis;

    Abstract : This thesis comprises five scientific papers, all of which are focusing on the inverse problem of reconstructing a dielectric permittivity which may vary in space inside a given domain. The data for the reconstruction consist of time-domain observations of the electric field, resulting from a single incident wave, on a part of the boundary of the domain under consideration. READ MORE
