1. Barium in the O horizon of soils near Sundsvall, northern Sweden : From local minerals or from anthropogenic emissions?
University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskapAbstract : Concentrations of potentially toxic metals in surface soils are important to investigate before building new residential areas. Prior to development of a residential area in Sundsvall, northern Sweden, it was observed that barium (Ba) concentrations in the soil at the site exceeded the guideline value of 200 mg kg-1 outlined by the Swedish Environmental Protection Agency.

2. Approximating Damping Coefficient of Bolted Joints using the Finite Element Method
University essay from KTH/HållfasthetsläraAbstract : Bolted joints are important due to their energy dissipation property in structures,but the damping mechanism is also highly nonlinear and localized. The goal ofthis thesis is to develop an accurate method for modeling bolted joint dampingin large structures using finite element (FE) software. READ MORE

4. Software Defined VNA : Measure Coupling Between Elements in an Antenna Array
University essay from Uppsala universitet/Signaler och systemAbstract : With improvements in hardware of antenna receivers, fully digital arrays have been made possible to use in real time systems. These systems have a greater complexity, with the advantage of more dynamic system design since the use of the communication system can be changed with only a software change. READ MORE

5. A numerical comparison of the thermoacoustics for different equivalence ratios for n-dodecane using LES
University essay from Lunds universitet/Institutionen för energivetenskaperAbstract : Klimatförändringarna påverkar vår värld och det behövs ett mer hållbart samhälle. Flygindustrin är i behov av förändring, men flygmotorer är mycket komplexa och tar tid att utveckla. Termoakustiska instabiliteter har kraften att förstöra en motor, men också att minska miljöpåverkan. READ MORE
