  1. 1. Geometric comparison of 3D city models for daylight simulations

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Johannes Lande Nyborg; [2022]
    Keywords : Geography; Physical Geography; Ecosystem Analysis; 3D city model; 3D building models; daylight access; daylight simulations; obstruction angle; free and open-source software; sustainable urban development; Geomatics; Earth and Environmental Sciences;

    Abstract : As cities keep densifying, essential resources such as daylight access become increasingly restricted. Therefore, prioritizing energy efficiency and enhancing the energy performance of our buildings is required for obtaining a sustainable urban environment. READ MORE

  2. 2. Effects of modified river cross-section geometry on hydraulic modelling performance: the slope break method

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Feixiong Qu; [2021]
    Keywords : ;

    Abstract : Remote sensing data has been widely used for large scale hydraulic modelling in the world. One of the most common ways to collect remote sensing data is by satellite. The digital elevation data observed from space is publicly accessible and covers almost all areas of the earth. However, the satellite cannot observe the river bathymetry. READ MORE

  3. 3. An automated unmanned aerial vehicle – structure from motion pipeline to create analysis-ready digital surface models for coastal monitoring

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Maximilian Rafael Huber; [2021]
    Keywords : physical geography; ecosystem analysis; geomatics; GIS; UAV; structure-from-motion; machine learning; coastal monitoring; Earth and Environmental Sciences;

    Abstract : Anthropogenic pressure on coastal areas continues to increase, thus intensifying coastal erosion. Coastal monitoring programs are therefore essential to prevent severe ecosystem and economic consequences. Successful coastal monitoring schemes require highly accurate analysis-ready Digital surface models (DSMs) derived using the same workflow. READ MORE

  4. 4. Taphonomic Markers and 3D-Modelling - A Non-Intrusive Method for Micromorphological Distinction of Metal and Stone Butchering Tools

    University essay from Lunds universitet/Historisk osteologi

    Author : Gianni Bello Cifuentes; [2021]
    Keywords : Osteology; Experimental Archaeology; 3D-modelling; Photogrammetry; Microphotogrammetry; Taphonomy; Bone Surface Modification; Cut Marks; Butchery Patterns; Digital Visualisation; Digital Zooarchaeology; Digital Osteology; History and Archaeology;

    Abstract : Digital tools in (zoo)archaeology have great potential for education, mediation, and research. Microphotogrammetric 3D-modeling offers new non-intrusive analytical approaches to old problems and questions. READ MORE

  5. 5. Implementation of Reaction Kinetics into Reactor Model Followed by Validation of the Reactor Model

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Rebecka Svensson; [2021]
    Keywords : Modeling; Reaction kinetics; Chemical Engineering; Technology and Engineering;

    Abstract : This master thesis project was performed in collaboration with Johnson Matthey. Johnson Matthey is a worldwide company working with sustainable technologies. The site in Perstorp, where this work was performed, focus on formaldehyde production. In order to continuously improve chemical processes, simulation and modeling are advantageous tools. READ MORE
