Experimental design to determine the effect of temperature and Mach number on entropy noise
The Osney Laboratory sought to create an entropy noise test rig that could determine the relationship between entropy noise and the flow parameters of temperature change and nozzle Mach number. The apparatus simulates entropy noise in an aero engine. In the test rig, compressed air enters an …

Numerical simulation and modelling of the effect of film cooling on entropy noise in a stator blade row
… of how film cooling flows interact with entropy waves, and their influence on entropy noise generation. A 2D numerical framework has been developed for preliminary understanding of the problem, and then analysis of the effect of film cooling on the entropy noise generation and entropy …

Indirect noise in non-isentropic flows
… of the combustor generates indirect combustion noise. Indirect noise is a large contributor to aircraft engine noise, therefore, it is an important aspect of the design of an aircraft engine. It is essential to model indirect noise because it can add to the thermoacoustic feedback and contribute …

Chinese word segmentation with a maximum entropy approach
In this thesis, we present a maximum entropy approach to Chinese word segmentation. Besides using features derived from gold-standard word-segmented training data, we also used an external dictionary and additional training corpora of different segmentation standards to further improve segmentation …
