  1. 21. Height determination by GPS : A practical experiment in central Sweden

    Författare :Stig-Göran Mårtensson; Högskolan i Gävle; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Division of Geodesy Reports; Surveying; Lantmäteri;

    Sammanfattning : GPS as a height measuring tool has been widely introduced for solving various tasks within the fields of Geodesy and Engineering Surveying. The obvious advantage of not needing lines of sight when acquiring height differences is, however, darkened by the fact that GPS and traditional spirit levelling have fundamentally different reference systems for heights.

  3. 22. Ground Movements in the Zagros Fold-Thrust Belt of SW Iran Measured by GPS and InSAR Compared to Physical Models

    Författare :Faramarz Nilfouroushan; Christopher Talbot; Hemin Koyi; Christophe Vigny; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Earth sciences; Zagros fold-thrust belt; deformation; GPS; InSAR; Physical modeling; tectonics; convergent settings; basal friction; Geovetenskap;

    Sammanfattning : This thesis uses geodetic satellite data to measure present-day crustal deformation in the Zagros fold-thrust belt (SW Iran). Geodetic-type measurements are also used in down-scaled models that simulate the surface deformations seen in convergent settings like the Zagros fold-thrust belt. LÄS MER

  4. 23. Assessment of PHEV potential to reduce fuel use in Sweden using GPS data for car movements

    Författare :Lars Henrik Björnsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; PHEV potential; battery size; GPS-logging; PHEV viability; PHEV; Sweden; electrification; Individual movement pattern;

    Sammanfattning : Roughly 30% of Sweden’s total greenhouse gas emissions originate from transport. These emissions need to be reduced to be able to reach the by The Swedish parliament adopted goal of a carbon neutral society in 2050. LÄS MER

  5. 24. Analysis of Retroreflection and other Properties of Road Signs

    Författare :Roxan Saleh; Hasan Fleyeh; Darko Babić; Högskolan Dalarna; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Road traffic signs; retroreflective sheeting material; night-time visibility; supervised machine learning; principal component analysis; prediction; linear regression;

    Sammanfattning : Road traffic signs provide regulatory, warning, guidance, and other important information to road users to prevent hazards and road accidents. Therefore, the traffic signs must be detectable, legible, and visible both in day and nighttime to fulfill their purpose. The nighttime visibility is critical to safe driving on the roads at night.

  7. 25. Digital Cognitive Companions for Marine Vessels : On the Path Towards Autonomous Ships

    Författare :Mårten Lager; Institutionen för datavetenskap; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Unmanned Surface Vessel; Autonomous Surface Vessel; Positioning; Virtual Reality; Human Robot Interaction; Particle Filter; Teleoperation;

    Sammanfattning : As for the automotive industry, industry and academia are making extensive efforts to create autonomous ships. The solutions for this are very technology-intense. Many building blocks, often relying on AI technology, need to work together to create a complete system that is safe and reliable to use. LÄS MER
