  1. 6. Geodetic analysis for the Very Long Baseline Interferometry Global Observing System

    Författare :Niko Petteri Kareinen; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; VLBI; GGOS; VGOS; digital back-ends; Earth rotation; DBBC; automated analysis; EOP; UT1;

    Sammanfattning : Very Long Baseline Interferometry (VLBI) is an essential technique forspace-geodesy. It realizes the International Celestial Reference Frame(ICRF) and provides a link between the Earth- and space-fixed coordinatesystems by directly observing all Earth Orientation Parameters (EOP)simultaneously.

  3. 7. Observation strategies for current and future geodetic very long baseline interferometry

    Författare :Niko Petteri Kareinen; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; VLBI; automated analysis; Intensives; Earth rotation; VGOS; GGOS;

    Sammanfattning : Geodetic Very Long Baseline Interferometry (VLBI) is an essential technique for space geodesy. It is uniquely capable of simultaneously observing all Earth Orientation Parameters (EOP) and directly giving access to the Earth’s rotation angle (related to Universal Time, UT1). LÄS MER

  4. 8. The Influence of Intentional and Situational factors on Enterprise Modelling Tool Acquisition in Organisations

    Författare :Janis Stirna; KTH; []
    Nyckelord :enterprise modelling; tool acquisition; situational factors;

    Sammanfattning : Enterprise Modelling (EM) tools are an important part ofevery EM application project. Continuous evolution of modellingmethods therefore requires efficient EM tool support. Extensiveefforts have been devoted to developing new EM tools andmodelling techniques. LÄS MER

  5. 9. STRENGTH TRAINING AFTER STROKE: EFFECTS ON MUSCLE FUNCTION, GAIT PERFORMANCE AND PERCEIVED PARTICIPATION

    Författare :Ulla-Britt Flansbjer; Geriatrik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; neuropsychology; neurophysiology; Reproducibility; Neurology; Rehabilitation; sceletal; Muscle; Cerebrovascular Accident; Gait; Neurologi; neuropsykologi; neurofysiologi;

    Sammanfattning : The overall aim of this thesis was to evaluate the effects of strength training on muscle function, gait performance and perceived participation in subjects with chronic mild to moderate post-stroke hemiparesis. A main impairment after stroke is reduced muscle strength. LÄS MER

  7. 10. Deep Learning for Active Fire Detection Using Multi-Source Satellite Image Time Series

    Författare :Yu Zhao; Yifang Ban; Andrea Nascetti; Josephine Sullivan; Cartalis Constantinos; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wildfire; Remote Sensing; Active Fire Detection; GOES-R ABI; Suomi-NPP VIIRS; Image Segmentation; Deep Learning; Gated Recurrent Units GRU ; Transformer.; Vilda Bränder; Fjärranalys; Aktiv Branddetektering; GOES- R ABI; Suomi-NPP VIIRS; Bildsegmentering; Djupinlärning; Gated Recurrent Units GRU ; Transformer; Geoinformatik; Geoinformatics;

    Sammanfattning : In recent years, climate change and human activities have caused increas- ing numbers of wildfires. Earth observation data with various spatial and temporal resolutions have shown great potential in detecting and monitoring wildfires. LÄS MER
