Engineered surfaces for enhanced performance using thin film coating
In the present study, two surface engineering technologies have been used for distinctively different purposes. Whilst nickel/aluminium has been deposited using unbalanced magnetron sputtering for thermal barrier applications, a separate investigation was carried out involving the deposition and …

Prediction of erosion in cementitious materials subject to high thermal and pressure loading
The project is a collaboration between the University of Central Lancashire and British Aerospace Warton concerned with the modelling of onset of failure in limestone concrete, due to hot jet exhaust gases impinging on the concrete surface. The temperature distribution was produced using a constant …

Applications of almost periodic functions and equivalent nonlinearities to identification and control of nonlinear systems
Correlation techniques for the identification of nonlinear systems are discussed in Chapter 1. The Volterra series expansion of the response of a nonlinear system is described, together with its counterpart in the frequency domain. Qosscorrelation methods for identifying the kernel functions which …

An experimental and theoretical study of piston ring lubrication
… was used with twenty-one transducers, of novel design, to allow the axial and circumferential distribution of lubricant film thickness to be monitored on an engine liner. This liner was fitted in an engine apparatus which had the additional facility of being able to measure the instantaneous …

Wavelet-like filter banks for multi-dimensional and multi-resolution signal processing
… By using the proposed method it is possible to design a filter bank with some desired properties for certain applications. Starting from the classical windowing method to generate a linearphase lowpass filter the author derived a set of wavelet-like filter coefficients by optimising a set of …

Spherical mosaic construction using physical analogy for consistent image alignment
The research contained in this thesis is an investigation into mosaic construction. Mosaic techniques are used to obtain images with a large field of view by assembling a sequence of smaller individual overlapping images. In existing methods of mosaic construction only successive images are …
