  1. 16. Repeated Path Planning for Mobile Robots in Dynamic Environments

    Författare :Maarja Kruusmaa; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; decision-making; mobile robot; case-based reasoning; navigation; dynamic environments; path planning;

    Sammanfattning : This thesis presents a global navigation strategy for repeated traverse of mobile robots in dynamic environments. The research is motivated by the fact that most real-world applications of mobile robotics imply repeated traverse between predefined target points in large, uncertain real-world domains. LÄS MER

  3. 17. Path Inference of Sparse GPS Probes for Urban Networks : Methods and Applications

    Författare :Mahmood Rahmani; Harilaos Koutsopoulos; Clas Rydergren; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; map-matching; path inference; sparse GPS probes; FCD; urban area; digital road network; Stockholm; taxi; iMobility Lab; MapViz; travel time; SRA - Transport; SRA - Transport;

    Sammanfattning : The application of GPS probes in traffic management is growing rapidly as the required data collection infrastructure is increasingly in place in urban areas with significant number of mobile sensors moving around covering expansive areas of the road network. Most travelers carry with them at least one device with a built-in GPS receiver. LÄS MER

  4. 18. On Path Planning and Path Following for Wheeled Mobile Robots

    Författare :Ferenc Weiczer; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The aim of the research documented and discussed in this thesis is to develop navigation methods including Path Planning, Location Measurement, and Path Following for supporting the navigation of wheeled mobile robots (WMR). The concept provides methods for path planning, i.e. LÄS MER

  5. 19. Verbs of Motion with Directional Prepositions and Prefixes in Xenophon's Anabasis

    Författare :Sanita Balode; Grekiska (antik och bysantinsk); []
    Nyckelord :HUMANIORA; HUMANITIES; Xenophon; Anabasis; prefixes; prepositional phrases; verbs of motion; surface elements; semantic elements; motion event; moving entity; landmark; source; path; goal; space; direction; trajectory; synonymy;

    Sammanfattning : The thesis compares different prepositions and verbal prefixes denoting direction in Ancient Greek. The corpus covers passages in Xenophon’s Anabasis where such directional elements are used. LÄS MER

  7. 20. Continuity and Change : Essays on path-dependence in economic geography and good food

    Författare :Pepijn Olders; Dominic Power; Henrik Mattsson; Anders Malmberg; Andrés Rodríguez-Pose; Uppsala universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; path dependence; continuity; change; expert opinion; economic geography; restaurants; low-emission vehicles; PDO PGI labels;

    Sammanfattning : How can it be, that in our rapidly changing world certain things remain recognisably the same for such a long time? This dissertation is concerned with the economic geography of path-dependence and seeks to explain selected everyday examples of continuity and change. How can French restaurants and chefs be successful for decades despite changes in taste? Why are cars powered by fossil fuels still around while there are many novel and cleaner alternatives? What explains the re-invention of local food products in spite of the influx of many new products from around the world? These are the question this dissertation tries to explain as spatial expressions of ‘path-dependence’. LÄS MER
