6. Sound Insulation at Low Frequencies
Abstract : The airborne sound transmission through building partitions at low frequencies was studied. The definition of the sound reduction index as a measure of sound insulation has been examined by means of extensive numerical simulations in 3-D domains. The simulations were based on the wave theoretical acoustics. READ MORE

7. Multichannel Audio Signal Processing : Room Correction and Sound Perception
Abstract : This thesis concerns and combines multichannel sound reproduction, digital room correction, audio signal processing, and human sound perception. It investigates perceived sound quality and new methods to improve timbral and spatial fidelity of loudspeaker-based multichannel sound reproduction in reverberant environments. READ MORE

9. Modeling and Control of EGR on Marine Two-Stroke Diesel Engines
Abstract : The international marine shipping industry is responsible for the transport of around 90% of the total world trade. Low-speed two-stroke diesel engines usually propel the largest trading ships. This engine type choice is mainly motivated by its high fuel efficiency and the capacity to burn cheap low-quality fuels.
