    Author : Berkant Savas; Lars Eldén; Lieven De Lathauwer; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Volume; Minimization criterion; Determinant; Rank deficient matrix; Reduced rank regression; System identification; Rank reduction; Volume minimization; General algorithm; Handwritten digit classification; Tensors; Higher order singular value decomposition; Tensor approximation; Least squares; Tucker model; Multilinear algebra; Notation; Contraction; Tensor matricization; Newton s method; Grassmann manifolds; Product manifolds; Quasi-Newton algorithms; BFGS and L-BFGS; Symmetric tensor approximation; Local intrinsic coordinates; Global embedded coordinates; ; Numerical analysis; Numerisk analys;

    Abstract : In many fields of science, engineering, and economics large amounts of data are stored and there is a need to analyze these data in order to extract information for various purposes. Data mining is a general concept involving different tools for performing this kind of analysis. READ MORE

  4. 2. Getting to know Trioza apicalis (Homoptera: Psylloidea) – a Specialist Host-Alternating Insect with a Tiny Olfactory System

    Author : Lina Kristoffersen; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physiology of invertebrates; Djurs anatomi och morfologi; Entomologi; plant parasitology; Entomology; Ekologi; Ecology; glomeruli; antennal lobe; olfactory receptor neurons electrophysiology; antennae; behaviour; olfaction; Sternorrhyncha; psyllid; Ryggradslösa djurs fysiologi; animal morphology; Animal anatomy; växtparasitologi;

    Abstract : This thesis comprises ecological, morphological and physiological studies of the carrot psyllid Trioza apicalis (Homoptera: Psylloidea) with particular focus on olfaction. Data from inventories of winter habitats suggest that T. apicalis prefer Picea abies over Pinus sylvestris and Juniperus communis as winter hosts. READ MORE

  5. 3. Sparse Modeling of Harmonic Signals

    Author : Filip Elvander; Statistical Signal Processing Group; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; multi-pitch estimation; sparse modeling; convex optimisation; inharmonicity; sparse recursive least squares; adaptive signal processing; optimal transport distance;

    Abstract : This thesis considers sparse modeling and estimation of multi-pitch signals, i.e., signals whose frequency content can be described by superpositions of harmonic, or close-to-harmonic, structures, characterized by a set of fundamental frequencies. READ MORE

  6. 4. Chemometric methods for analysis of spectroscopic data from batch process monitoring

    Author : Erik Furusjö; KTH; []
    Keywords : in situ spectroscopy; reaction monitoring; organic synthesis; solubility; crystallization; multivariate calibration; curve resolution; kinetic model; reaction rate constant; activation energy; target testing; bootstrap;

    Abstract : Understanding of a process is essential for processdevelopment, optimisation and scale-up. In situ spectroscopy isan attractive measurement technique that can increase processunderstanding, since samples need not be retrieved from theprocess mixture. READ MORE

  7. 5. Synthesis and Characterisation of Conjugated Polymers with High Electron Affinity

    Author : Maria Jonforsen; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; light-emitting diode; solar cell; quinoxaline; conjugated polymer; photodiode; 4-b]pyrazine; pyrido[3; synthesis; photo-oxidation; electron affinity; pyridine;

    Abstract : This thesis describes synthesis and characterisation of conjugated polymers with high electron affinities. Polymers of this type are desired, for example, for use in light-emitting devices or as electron accepting material in photodiodes/solar cells. READ MORE
