1. 1. The influence of the built environment on the climate in different Swedish urban fabrics

   University essay from Högskolan Dalarna/Institutionen för information och teknik

   Author : Reem Mutwali; [2023]
   Keywords : Urban heat island; Urban morphology; The urban weather generator;

   Abstract : The urban heat island effect is usually disregarded when considering energy-efficient measures for the built environment. This study aims to present and analyze the effect of the urban built environment on the Swedish urban climate. This analysis is done in terms of assessing the mean urban heat island and monthly average air temperature. READ MORE

3. 2. Implementing spatial variance in the rate of photolytic breakdown of NO2 in urban street canyons

   University essay from Lunds universitet/Institutionen för energivetenskaper

   Author : Fabian Friberg; [2022]
   Keywords : cfd; computational fluid dynamics; NOx; street canyon; NO2; NO; O3; photolysis; OpenFOAM; Physics and Astronomy;

   Abstract : In this study a module for calculating the solar exposure of individual fluid cells was developed to more accurately represent the effect of photolysis on the pollutant dispersion in an urban street canyon. The module was tested and validated on 12 different cases, each with a different geographical location, time of year and/or time of day. READ MORE

4. 3. Development of GNSS Type Processing for the Characterization of the Mobile Propagation Channel

   University essay from KTH/Fastigheter och byggande

   Author : Adrien Bardou; [2021]
   Keywords : LMS Channel; Multi-paths; GNSS; SCHUN; Simulation; LMS-kanal; flerv¨agar; GNSS; SCHUN; Simulering;

   Abstract : Mobile communication systems are undergoing significant development on increasingly wide frequency bands (5G in particular). To support this development, a detailed characterization of the propagation of electromagnetic waves in L, S and C band between a station (satellite, airborne or ground) and a mobile platform is necessary to analyze and model the phenomena that have a decisive impact on the performance, availability and operability of systems.
