  1. 6. Functional Hodrick-Prescott Filter

    Författare :Hiba Nassar; Astrid Hilbert; Alexander Meister; Linnéuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Inverse problems; adaptive estimation; Hodrick-Prescott filter; smoothing; trend extraction; Gaussian measures on a Hilbert space.; Mathematics; Matematik;

    Sammanfattning : The study of functional data analysis is motivated by their applications in various fields of statistical estimation and statistical inverse problems.In this thesis we propose a functional Hodrick-Prescott filter. This filter is applied to functional data which take values in an infinite dimensional separable Hilbert space. LÄS MER

  3. 7. Data association algorithms and metric design for trajectory estimation

    Författare :Abu Sajana Rahmathullah; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; metrics; smoothing; expectation maximization; Gaussian mixtures; data association; Trajectory estimation;

    Sammanfattning : This thesis is concerned with trajectory estimation, which finds applications in various fields such as automotive safety and air traffic surveillance. More specifically, the thesis focuses on the data association part of the problem, for single and multiple targets, and on performance metrics. LÄS MER

  4. 8. fMRI for mapping the plastic somatotopy of primary somatosensory cortex - Development and clinical applications

    Författare :Andreas Weibull; Malmö Medicinsk strålningsfysik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; smoothing; physiological noise; spatial resolution; primary somatosensory cortex; cortical reorganisation; brain plasticity; fMRI; partial volume effects;

    Sammanfattning : Functional magnetic resonance imaging (fMRI) is a widely used tool for studying brain function in vivo. The technique is based on acquiring brain images sensitive to the physiological response following neural activation, and hence, allows brain activity to be examined and documented. LÄS MER

  5. 9. Inertial Navigation and Mapping for Autonomous Vehicles

    Författare :Martin Skoglund; Fredrik Gustafsson; Thomas Schön; Tim Bailey; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SLAM; Inertial Navigation; Filtering; Smoothing; Cameras; Optimisation; Autonomous;

    Sammanfattning : Navigation and mapping in unknown environments is an important building block for increased autonomy of unmanned vehicles, since external positioning systems can be susceptible to interference or simply being inaccessible. Navigation and mapping require signal processing of vehicle sensor data to estimate motion relative to the surrounding environment and to simultaneously estimate various properties of the surrounding environment.

  7. 10. Svenska småföretags användning av reserveringar för resultatutjämning och intern finansiering

    Författare :Håkan A. Andersson; Lars G. Hassel; Kerstin Nilsson; Lars Lindbergh; Lars Fallan; Umeå universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; allowance rules; tax credits; sole proprietorships; income smoothing; internal financing; tax allocation reserve; cross-sectional studies; financial and non-financial variables; logistic regression model.; Business studies; Företagsekonomi; företagsekonomi; Business Studies;

    Sammanfattning : Small firms often have inadequate access to the capital necessary for sucessful management. The Swedish Government introduced in the mid-1990s allowance rules that facilitate retention of profit for sole proprietorships and partnership firms. LÄS MER
