16. Empirical Verification of an Acoustic Estimation of a Rocket Engine : A Comparison Between Estimated and Measured Noise of a Rocket Engine
University essay from KTH/Skolan för industriell teknik och management (ITM)Abstract : The noise of a rocket engine is a complex and complicated phenomenon which has been studied for more than half a century [1]. There are many sources to this noise, but due to its great potential impact to the surrounding structures, including the vehicle itself, it is important to have a model to estimate the acoustic environment the engine produces.

17. Synthetic gel particle formation for acoustofluidic applications
University essay from Lunds universitet/Avdelningen för Biomedicinsk teknikAbstract : Cancer cell detection by particle sorting systems is a very challenging field which could help to discover cancers at an earlier stage. Acoustophoresis used as a particle sorting system is based on the difference between the acoustic properties of particles and the medium. READ MORE

20. Hydroacoustic Modelling of Podded Propulsion System : Underwater Radiated Noise Prediction Using ANSYS
University essay from KTH/Teknisk mekanikAbstract : Ocean noise pollution is an invisible but growing threat. There are many sources of sound in the ocean but human underwater radiated noise, in particular from shipping is one of the most prominent one. Ocean noise pollution can interfere or sometimes even directly harm marine life. READ MORE
