1. Vibrational signals as indicators of soil fauna health? : A novel approach to environmental monitoring of ants
Master-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskapSammanfattning : Soil fauna provides processes of crucial importance for ecosystem functions, but our ability to observe their actions often depend on destructive methods where the integrity of the studied environment (the soil) is compromised. In this study, I develop and test a new generation of environmental monitoring tools that utilize vibrations made by soil macrofauna to inform about their performance and health. LÄS MER
2. Environmental Testing of Large Components
Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)Sammanfattning : As the industry is being reshaped concentrically around sustainability, the consumption of fossil fuels is targeted to decrease day by day. As a consequence of that, a righteous rise of electricity as energy source prevails in different branches of industry. LÄS MER
3. Vibration analysis and testing of a 6U cubesat propulsion system
Master-uppsats, KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanikSammanfattning : Space industry has been booming in the recent times, investments have not justbeen made on satellites and launch vehicles but also on space sustainability. Spaceindustry has its users in national agencies, private commercial agencies, academia andexperimental organisations. LÄS MER
4. Investigation of Vibration in Electrical Circuit used in Maritime Applications
Master-uppsats, KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanikSammanfattning : This paper presents an investigation of a problem discovered in electronic equipment where mechanical load was the leading cause of the issue. Finite Element Analysis is used to investigate vibration issues in soldering and components. Simulations are performed with ANSYS modal and random vibration package. LÄS MER
5. Modelling of contacts in Adams flex bodies using Mamba
Master-uppsats, KTH/FordonsdynamikSammanfattning : Simulations are a powerful tool used to reduce development time and cost in the vehicle industry. However, the models used in simulations are simplifications of reality, and there are commonly contradicting requirements between accuracy and computational efficiency. LÄS MER
