6. Measurements, Analysis Techniques and Experiments in Sound and Vibration : Applied to Operational MRI Scanners and in Remote Laboratories
Abstract : High quality noise and vibration measurements outside of a laboratory environment on real life structures and applications are not trivial. True boundary and operating conditions enforce unique challenges on the measurements. Measurements in hazardous situations such as high magnetic fields, and high temperature environments, etc. READ MORE

7. Failure Monitoring and Asset Condition Assessment in Water Supply Systems
Abstract : In this thesis, different aspects of failure management in urban water supply systems are discussed. As assets are getting older, the number of pipe failures is increasing and an efficient failure management strategy becomes important. READ MORE

8. Thermodynamic Modelling and Performance of Combined Solid Oxide Fuel Cell and Gas Turbine Systems
Abstract : Solid oxide fuel cells (SOFCs) are a ceramic type of fuel cell operating at elevated temperatures. By utilising the thermal energy from the SOFC in a heat engine, a hybrid cycle with high performance can be achieved. One promising concept is a pressurised SOFC in combination with a recuperated gas turbine cycle. READ MORE

9. Structural-acoustic vibrations in wooden assemblies : Experimental modal analysis and finite element modelling
Abstract : This doctoral thesis concerns flanking transmission in light weight, wooden multi-storey buildings within the low frequency, primarily 20-120 Hz. The overall aim is to investigate how the finite element method can contribute in the design phase to evaluate different junctions regarding flanking transmission. READ MORE

10. Modeling and Performance of Gas Turbine Cycles with Various Means of Blade Cooling
Abstract : A method for simulating the cooled gas turbine is demonstrated. Based on equations and other knowledge found in the literature, a first-law thermodynamic, non-dimensional model is established and implemented in the equation-solving, programmable software IPSEpro. READ MORE
