6. Acoustic Characterization of Turbochargers and Pipe Terminations
Abstract : In search for quieter engines there is a need for a better understanding of the acoustic properties of engine intake and exhaust system components. Besides mufflers which have the purpose of reducing pressure pulses originating from the internal combustion (IC) engine, there are many components in a modern car exhaust and intake system, e.g. READ MORE

7. Feature-Based Image Processing for Rendering, Compression, and Visual Search
Abstract : Visual communication, vivid, meaningful, and creative, permits a way to express information visually. The communication media, by images, graphs and videos, passes informative color and shape to human perception sensors. READ MORE

8. Geometry parameterisation and response surface-based shape optimisation of aero-engine compressors
Abstract : The main goal in jet engine design is to achieve light, compact and highly efficient systems while reducing the cost and design times. Traditionally, the design has been based on trial-and-error procedures, which count on the skills and experience of the designer to suggest design improvements. READ MORE

9. Improved remaining useful life estimations for on-condition parts in aircraft engines
Abstract : This thesis focuses on obtaining better estimates of remaining life for on-condition (OC) parts in aircraft engines. Aircraft engine components are commonly classified into three categories, life-limited parts (LLP), OC-parts and consumables. Engine maintenance typi-cally accounts for 10% to 20% of aircraft-related operating cost. READ MORE

10. Aspects of Efficient Parameter Estimation for Diesel Oxidation Catalysts
Abstract : In this thesis the objective was to tune the model parameters of diesel oxidation catalysts (DOC) to measurement data from engine rig experiments in an efficient manner. The scope was however not limited to the algorithm of parameter search alone but instead included the whole process starting with the design of experiments. READ MORE
