1. 6. Inverse Atmospheric Dispersion Modeling in Complex Geometries

   University essay from Umeå universitet/Institutionen för fysik

   Author : Charlie Pelland; [2022]
   Keywords : atmospheric dispersion modeling; dispersion modeling; invers dispersion modeling; atmospheric dispersion; invers atmospheric dispersion; CFD; computational fluid dynamics; radioactive release; openfoam; CRBN; dry deposition; dry deposition velocity; scavenging effect; wet deposition; optimization model; Reynolds Averaged Navier-Stokes; adjoint mode; time-dependent rain simulation; time-dependent rain; time dependent rain simulation; time dependent rain;

   Abstract : In the event of a radioactive release in an urban environment the consequent response mustbe swift and precise. As soon as first responders have correct information, they can make anaccurate risk assessment. However, if the position, release rate and time of the radioactiverelease is unknown it is hard to know how the pollutant will spread. READ MORE

3. 7. 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

4. 8. Creating a workflow of 3D building data in a municipality context

   University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Author : Tom Bendiksen; [2021]
   Keywords : Physical Geography and Ecosystem analysis; 3D City Models; 3D Building Models; CityGML; CityJSON; 3DCityDB; NS Building; 3D City Information Modeling; Geomatics; Earth and Environmental Sciences;

   Abstract : 3D city models are valuable tools for visualization and analytical purposes in the urban environment. A popular format for city models is CityGML, an open data model that can be used for storage and exchange of 3D city models. READ MORE

5. 9. Design, implementation and evaluation of a daylight estimation tool using 3D city model data

   University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Author : Peter Nezval; [2021]
   Keywords : 3D city model; CityJSON; solar energy; free and open-source software; 3D feature extraction; solar urban planning; sustainable urban development; geomatics; Earth and Environmental Sciences; Technology and Engineering;

   Abstract : Solar energy is an important component of sustainable urban development. However, it is still not reaching its full potential due to several reasons. One of them is a lack of free tools based on open geodata capable of estimating solar energy (daylight) metrics on building features, e.g. READ MORE

6. 10. Mapping Noise Pollution with Open-source GIS

   University essay from Högskolan i Gävle/Samhällsbyggnad

   Author : Faustina Lina Yeboah; [2021]
   Keywords : Road traffic noise; CNOSSOS-EU; noise exposure; Lday; Levening; Lnight; Lden;

   Abstract : In a time when urban areas continue to expand, environmental noise pollution especially from road traffic remains a big challenge. This study was aimed at using open-source GIS tools to predict road traffic noise pollution using the mid-sized city of Gävle as a case study. READ MORE
