  1. 1. Exploring Strategies for the Combination of Multiple Space-geodetic Techniques

    Författare :Periklis Diamantidis; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Space Geodesy; GNSS; Combination on the Observation Level; EOP; Reference Systems; VLBI; Local Ties;

    Sammanfattning : Space-geodetic techniques are based on signal acquisition from extraterrestrial radio sources that can be used to infer geodetic positioning and define Earth-fixed and inertial reference systems. These techniques, which include Very Long Baseline Interferometry (VLBI) and Global Navigation Satellite Systems (GNSS) among others, exhibit different strengths and weaknesses in recovering parameters of interest.

  3. 2. Combination of space-geodetic techniques in the era of VGOS and multi-GNSS

    Författare :Periklis Diamantidis; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Local Ties; EOP; Reference Systems; GNSS; VLBI; Combination on the Observation Level; multi-GNSS; Space Geodesy; VGOS;

    Sammanfattning : The definition and maintenance of accurate and stable Earth-fixed and inertial reference frames is crucial in studying, among else, geophysical and geodynamical phenomena, precise positioning, and space navigation. The tools used to this end are space-geodetic techniques, like e.g. LÄS MER

  4. 3. Deep Learning for Geo-referenced Data : Case Study: Earth Observation

    Författare :Nosheen Abid; Marcus Liwicki; Muhammad Zeshan Afzal; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Artificial Intelligence; Machine Learning; Earth Observation; Computer Vision; Machine Learning; Maskininlärning;

    Sammanfattning : The thesis focuses on machine learning methods for Earth Observation (EO) data, more specifically, remote sensing data acquired by satellites and drones. EO plays a vital role in monitoring the Earth’s surface and modelling climate change to take necessary precautionary measures. LÄS MER

  5. 4. In the mind of the beholder : perspectives on healthcare managers' leadership

    Författare :Caroline Lornudd; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The managerial mission in healthcare services today entails challenging conditions that have implications for healthcare managers’ leadership. These circumstances, in combination with reports in the literature describing a consistent association between leadership and employee outcomes, have heightened the need for research on how healthcare manager’s leadership relates to psychosocial aspects in the workplace and how leadership can be supported.

  7. 5. Visioner och verkligheter : Kommunikationen om företagets strategi

    Författare :Catrin Johansson; Lowe Hedman; Börje Alström; Sven Windahl; Uppsala universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Media and communication studies; organizational communication; organizational processes; corporate strategy; vision; mission and values; management of meaning; sense making; Balanced Scorecard; participant observation; discourse analysis; face; framing and footing; Medie- och kommunikationsvetenskap; Media and communication studies; Medie- och kommunikationsvetenskap; Medie- och kommunikationsvetenskap; Media and Communication Studies; Other social sciences;

    Sammanfattning : The starting point for this study is the question of why organizational visions are often interpreted by employees as unintelligible and insignificant. The knowledge gap in this area makes the study of communication about vision and goals both urgent and interesting. LÄS MER
