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

    University essay from Uppsala universitet/Avdelningen för systemteknik

    Author : David Smeds; [2024]
    Keywords : ;

    Abstract : 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. READ MORE

  5. 4. I sökandet efter en grundton : en reflekterande berättelse om konceptuellt tänkande inom landskapsarkitektur

    University essay from SLU/Dept. of Urban and Rural Development

    Author : Emelie Lenning; [2024]
    Keywords : Konceptuell landskapsarkitektur; konceptutveckling; abstraktion; mening; storytelling; estetik; designmetod; designverktyg;

    Abstract : Landskapsarkitekter skulpterar, regisserar och komponerar våra livsmiljöer. Det är ett hantverk som kräver sin penna, sitt öra och ett känsligt sinne. Samtidigt befinner sig landskapsarkitekter i en kontext där en samhällelig utveckling knuffar regin in i stela processer och effektiviserade system (Bornemark 2018). READ MORE

  6. 5. Ensuring safe docking maneuvers on floating platform using Nonlinear Model Predictive Control (NMPC)

    University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Author : Federico Gatti; [2024]
