16. Come Fly with Me (Sustainably) : Pathways to Sustainable General Aviation and Private Pilot Training
Magister-uppsats, Högskolan i Gävle/MiljövetenskapSammanfattning : Whereas commercial aviation is attempting to achieve the reduction of its substantial carbon footprint, general aviation’s (GA) climate change contribution is negligibly small, which is why the sector is facing other sustainability challenges mainly entailing the operation of dated technology and aircraft, increasing regulatory constraints, rising costs, noise emissions, and popular discontent, as well as remaining the last mobility sector in the world to still use leaded fuels. Throughout recent years, there have been remarkable sustainability trends in GA as well as heightened efforts to improve its emissions profile (noise, pollutants, CO2) and environmental reputation, for instance by the increased use of electric aircraft, especially for private pilot training.

17. A comparison of 2D and 3D resistivity surveys for 3D inversion imaging
Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknikSammanfattning : Following study focuses on electrical resistivity surveying and how it can be used as an exploration method to increase knowledge of subsurface structures. Future scenarios with increasing population and rapid urbani-zation, put high demands on reliable infrastructure; safe foundations, un-derground structures, environmental safety and access to resources.

18. Det gröna torget : hur kan vi förbättra biodiversiteten på torg?
Kandidat-uppsats, SLU/Dept. of Landscape Architecture, Planning and Management (from 130101)Sammanfattning : Urbana miljöers utbredning har haft stor påverkan på den naturliga miljön och många djur och insektsarters naturliga habitat har försvunnit och ersatts av hårdgjord markyta och byggnader. Detta har inte bara påverkat djur och insektsvärlden utan även oss människor negativt i form av förorenad luft, översvämningar och störande buller från fordon. LÄS MER
19. Development of Acoustic Simulation Methods for Exhaust Systems
Master-uppsats, KTH/Optimeringslära och systemteoriSammanfattning : Noise pollution is a growing concern due to its harmfulness to human health. Heavy vehicles powered by internal combustion engines stands for a major part of the environmental noise, why noise reduction is an increasing priority in enginve development. LÄS MER
20. The impact of noice pollution and vibrations on nearby buildings : How is the school Kulturama affected by noise and vibrations from the 'nya tunnelbana' project?
Kandidat-uppsats, KTH/Byggteknik och designSammanfattning : To meet the needs of the growing city of Stockholm, a large-scale project to expand the subway has been initiated. The tunneling involved in the project causes several disturbances, in terms of vibration and noise pollution, on the surroundings. This is problematic as vibration and noise pollution has been shown to have a negative health impact. LÄS MER
