21. Beam-steered Modulation in Advanced Antenna System
Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknikSammanfattning : The newer spectral bands in millimeter-wave (mm-Wave) spectrum over the last few years have made higher data rates possible and improved quality of service for the users, but it possesses new challenges to design spectral agile radios. Power Amplifiers (PA) are a crucial analog component connected to Multiple input multiple output (MIMO) antennas which inherits non-linear effects. LÄS MER
22. Tekniska lösningar för att skapa gynnsamma förhållanden i fastigheter utrustade med laddpunkter : En simuleringsstudie för projektering av olika energilösningar vid utbyggnad av laddningsinfrastruktur i fastigheter
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/ElektricitetsläraSammanfattning : The electrification of the Swedish vehicle fleet is happening at a record pace and the proportion of rechargeable vehicles is increasing rapidly. An electric vehicle fleet will result in an extra demand of electrical power from an electricity grid that is already heavily strained. LÄS MER
23. Improved Bridge Load Capacity via Dynamic Train-Track-Bridge Interaction : Assessing the dynamic amplification factor caused by measured track irregularities for rail freight transport
Master-uppsats, KTH/Bro- och stålbyggnadSammanfattning : The carbon impact of transportation is large and requires sustainable solutions. With expected population growth, rail transportation plays a vital role in facilitating a greener Europe. The expansion of the rail infrastructure is therefore of essential importance for future challenges. LÄS MER
24. CFD Analyses for Wind Load AssessmentCFD Analyses for Wind Load Assessment : Wind-induced vibrations in the Bomarsunds Bridge hangers
Master-uppsats, KTH/Bro- och stålbyggnadSammanfattning : The trend in recent years of building longer and slender bridge components has introduced new challenges to ensure their stability and strength. This master thesis focuses on the effects of wind-induced vibrations in the context of long, slender arch bridge components, particularly the recently constructed Bomarsunds Bridge in Åland, Finland.

25. Analysis of Footbridge Comfort Vibrations
Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Byggnadsmekanik; Lunds universitet/Institutionen för byggvetenskaperSammanfattning : The aim of this master's thesis was to investigate and increase the knowledge of how different parameters affect the dynamic properties of steel beam bridges used for pedestrian traffic. Steel footbridges are commonly used due to their high strength and low weight. LÄS MER
