  1. 1. Online trajectory planning and observer based control

    Författare :David A. Anisi; Xiaoming Hu; Daizhan Cheng; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computational Optimal Control; Receding Horizon Control; Mission Uncertainty; Safety; Task Completion; Consensus Problem; Simultaneous Arrival; Adaptive Grid Methods; Missile Guidance; Nonlinear Observer Design; Active Observers; Non--uniformly Observable Systems; Mobile Robotic Systems; Intrinsic Observers; Differential Geometric Methods; Euler-Lagrange Systems; Contraction Analysis.; Optimization; systems theory; Optimeringslära; systemteori;

    Sammanfattning : The main body of this thesis consists of four appended papers. The first two consider different aspects of the trajectory planning problem, while the last two deal with observer design for mobile robotic and Euler-Lagrange systems respectively. LÄS MER

  3. 2. Mapping and Merging Using Sound and Vision : Automatic Calibration and Map Fusion with Statistical Deformations

    Författare :Gabrielle Flood; Matematik LTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Time of arrival; TOA; Time-difference of arrival; TDOA; Subsample methods; Uncertainty measure; Constant offset; RANSAC; Map merging; Map fusion; Change detection; Collaborative SLAM; Structure from motion; SfM; SLAM; Mapping; Localisation; Registration; Sparse maps; Point clouds;

    Sammanfattning : Over the last couple of years both cameras, audio and radio sensors have become cheaper and more common in our everyday lives. Such sensors can be used to create maps of where the sensors are positioned and the appearance of the surroundings. LÄS MER

  4. 3. Trombolys och biokemiska markörer : i den prehospitala fasen av akuta koronara syndrom

    Författare :Leif Svensson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Prehospital thrombolysis; acute myocardial infarction. Biochemical markers; prehospital phase.;

    Sammanfattning : Efficacy of thrombolytic therapy among patients with ST-segment elevation myocardial infarction is time dependent. The earlier treatment can be started the more powerful are the effects on reducing infarct size, preservation of ventricular function and reducing long and short-term mortality. LÄS MER

  5. 4. Minimal Problems and Applications in TOA and TDOA Localization

    Författare :Simon Burgess; Mathematical Imaging Group; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Calibration-Free Localization; TOA; TDOA; RSSI Localization;

    Sammanfattning : The central problem of this thesis is locating several sources and simultaneously locating the positions of the sensors. The measurements captured by the sensors are time of arrival (TOA), time difference of arrival (TDOA), unsynchronized TDOA, or received signal strength indication (RSSI), all a variation of distance measurement between sensors and sources.

  7. 5. Dynamic Source Models of Icelandic Earthquakes and Teleseismic Tomograhy along the TOR array

    Författare :Z. Hossein Shomali; Göran Ekström; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Earth sciences; Geovetenskap; Earth sciences; Geovetenskap; Geofysik med inriktning mot seismologi; Geophysics with specialization in Seismology;

    Sammanfattning : This thesis describes new inversion-oriented methodological developments and their seismological applications. In the first study presented the dynamic source parameters of some local Icelandic earthquakes are studied by employing a time domain moment tensor inversion method. LÄS MER
