    Författare :Lars Harrie; Institutionen för naturgeografi och ekosystemvetenskap; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; multiple representation database; automated cartographic generalisation; incremental generalisation; displacement; cartographic constraints; object-oriented database;

    Sammanfattning : Automation is increasingly important in producing and maintaining cartographic data sets. This thesis deals with automatic methods to propagate updates between cartographic data sets. LÄS MER

  3. 2. An Optimisation Approach to Cartographic Generalisation

    Författare :Lars Harrie; Centrum för geografiska informationssystem (GIS-centrum); []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; incremental generalisation; multiple representation; least-squares method; optimisation; cartographic constraints; displacement; cartographic generalisation; graphic generalisation; map production; object-oriented spatial databases; Physical geography; geomorphology; pedology; cartography; climatology; Fysisk geografi; geomorfologi; marklära; kartografi; klimatologi; Technological sciences; Teknik;

    Sammanfattning : Cartographic generalisation is the process of simplifying a representation to suit the scale and purpose of a map. As such, generalisation has always been a central part in map production. This thesis is a contribution to the ongoing work on automating cartographic generalisation. LÄS MER

  5. 4. Lifelong Visual Localization for Automated Vehicles

    Författare :Peter Mühlfellner; Thorsteinn Rögnvaldsson; Roland Philippsen; Tom Duckett; Högskolan i Halmstad; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; vision-based localization; automated vehicles;

    Sammanfattning : Automated driving can help solve the current and future problems of individualtransportation. Automated valet parking is a possible approach to help with overcrowded parking areas in cities and make electric vehicles more appealing. In an automated valet system, drivers are able to drop off their vehicle close to a parking area. LÄS MER

  7. 5. Taking stock of large-scale lithium-ion battery production using life cycle assessment

    Författare :Mudit Chordia; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Brine; Spodumene; Lithium-ion battery; Lithium; Life cycle assessment; Giga-factory; Upscaling;

    Sammanfattning : Battery electric vehicles are being increasingly favored as an alternative to internal combustion engine vehicles (ICEVs). This is mainly due to their lower environmental impact when compared to ICEVs over the vehicle’s lifetime. LÄS MER
