6. 5G Positioning using Machine Learning
University essay from Linköpings universitet/ReglerteknikAbstract : Positioning is recognized as an important feature of fifth generation (\abbrFiveG) cellular networks due to the massive number of commercial use cases that would benefit from access to position information. Radio based positioning has always been a challenging task in urban canyons where buildings block and reflect the radio signal, causing multipath propagation and non-line-of-sight (NLOS) signal conditions.

7. Wind Unwind
University essay from Lunds universitet/Institutionen för arkitektur och byggd miljöAbstract : Wind turbines are most commonly located in remote areas to harness strong and constant winds, however, with the current growing rate of urbanisation, producing clean energy within the city closer to consumers is becoming crucial. Research has shown that the urban morphology has a strong capacity to influence air flow and ‘street canyons’ have the potential to channel the wind towards turbines in the urban scale. READ MORE

8. Vegetationens inverkan på det urbana klimatet : en studie om trädens effekt på en gatukanjonen i Malmö
University essay from SLU/Dept. of People and SocietyAbstract : Fysisk planering i Sverige har sedan länge inneburit att anpassa våra städer för ett kallt klimat. De pågående klimatförändringarna kommer dock kräva att den fysiska planeringen även omfattas av en anpassning för ett varmt sommarhalvårsklimat, där förekomsten av extrema väderhändelser kan komma att öka.

9. Mass conservative network model for convective net flow in a complex urban geometry
University essay from Umeå universitet/Institutionen för fysikAbstract : When simulating air flows in an urban environment, for e.g. pollutant dispersion investigations, today's main tool is advanced computational fluid dynamics simulations. These simulations take a lot of time and resources to perform, even for small geometries. READ MORE

10. Modelling near ground wind speed in urban environments using high-resolution digital surface models and statistical methods
University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapAbstract : Wind is a complex phenomenon and a critical factor in assessing climatic conditions and pedestrian comfort within cities. This master’s thesis attempts to quantify and model the relationship between near ground wind speed and urban geometry using two-dimensional raster data and variable selection methods based on Multiple Linear Regression.
