6. Evaluation of a heated inlet to reduce humidity induced error in low-cost particulate matter sensors
Master-uppsats, Lunds universitet/Ergonomi och aerosolteknologiSammanfattning : The number of low-cost particulate matter (PM) sensors available on the market has increased in recent years. They are affordable, compact and require no maintenance which means they easily can be deployed and utilized for real-time air monitoring. However, the accuracy of low-cost PM sensors has been reported to vary depending on several factors. LÄS MER
7. Atmospheric soot particle transformation from urban to rural
Kandidat-uppsats, Lunds universitet/Kärnfysik; Lunds universitet/Fysiska institutionenSammanfattning : The main objective of this work was to investigate if there is a contribution of aerosol from the urban region of Copenhagen at the rural station Vavihill. This was done by analyzing measurement data between 1st of January and the 28th of February 2013 measured with a Dierential Mobility Particle Sizer (DMPS), Soot Particle Aerosol Mass Spectrometer (SP-AMS), a Cloud Condensation Nuclei Counter (CCNC) and a NOx-analyzer.

8. Comparative analysis of winch-based wave energy converters
Kandidat-uppsats, KTH/Maskinkonstruktion (Inst.)Sammanfattning : Renewable energy sources are probably the future of the mankind. The main points advocating wave energy in particular include its huge potential, low environmental impact and availability around the globe. LÄS MER
9. Two-Dimensional Radiation Field Map of a Be-based Source
Kandidat-uppsats, Lunds universitet/Kärnfysik; Lunds universitet/Fysiska institutionenSammanfattning : The aim of this project was to measure the profile of the radiation exiting an aperture of the Aquarium at the Source Testing Facility at the Division of Nuclear Physics at Lund University. So far, the outgoing beam of radiation at the aperture of the Aquarium has been assumed to be uniform. LÄS MER
10. Resolution Improvements and Physical Modelling of a Straw Tracker : The NA62 Experiment at CERN
Master-uppsats, Umeå universitet/Institutionen för fysikSammanfattning : Lab measurements and Monte Carlo simulations have been carried out for the evaluation of the Straw-type detectors used in the NA62 experiment at CERN. In addition, analyses of experiment data was used in corrections to improve the reconstruction of particle tracks, ultimately leading to improved resolution of the detector system as a whole. 97.
