  1. 1. A space-time shape for easier spatiotemporal visualization in traffic networks

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Avdelningen för systemteknik

    Författare :David Smeds; [2024]
    Nyckelord :;

    Sammanfattning : Modern big data systems are enabling new possibilities that never were thought possible in the past. The ability to gather massive data on an individual level has made fields like space-time geography bloom in the latest decennia. The usage of shapes in a 3D space allows us to visualize certain phenomena over time. LÄS MER

  3. 2. Station-level demand prediction in bike-sharing systems through machine learning and deep learning methods

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Nikolaos Staikos; [2024]
    Nyckelord :Physical Geography; Ecosystem Analysis; Bike-sharing demand; Machine learning; Deep learning; Spatial regression; Graph Convolutional Neural Network; Multiple Linear Regression; Multilayer Perceptron Regressor; Support Vector Machine; Random Forest Regressor; Urban environment; Micro-mobility; Station planning; Geomatics; Earth and Environmental Sciences;

    Sammanfattning : Public Bike-Sharing systems have been employed in many cities around the globe. Shared bikes are an efficient and convenient means of transportation in advanced societies. Nonetheless, station planning and local bike-sharing network effectiveness can be challenging. LÄS MER

  4. 3. Identification and evaluation of solutions for long-haul electric road freight.

    Master-uppsats, Linköpings universitet/Logistik- och kvalitetsutveckling

    Författare :Amanda Lundström; Gustav Lindén; [2023]
    Nyckelord :Electric road freight; long-haul; TCO; Tripple bottom line;

    Sammanfattning : Road freight transportation is important for the development of the global economy and, at the same time, one of the most destructive businesses when it comes to the environment and human health. As societies evolve, the need for freight transportation increases and the transport demand cannot in a sustainable way be fulfilled with the use of diesel trucks as it is done today. LÄS MER

  5. 4. Konsten att få alla med på tåget : En studie av Svenska Röda Korsets samarbete med internationella aktörer för transport och utväxling av krigsfångar 1915–1918
