Spectral Analysis in Engineering, Concepts and Cases
Twelve years ago, we suggested a course called 'Probability and Spectral Techniques' as part of a Science and Engineering Research Council programme of postgraduate training for engineers. We thought the ability to model wind and wave forces dynamically, rather than as a static wave, was an essential skill for modern engineering. Other important applications ranged from the design of vibration controllers to the measurement of surface finish. We thoroughly enjoyed giving the course, at the University of Newcastle upon Tyne, on several occasions, and hope the participants learnt as much as we did.
This book is based on the course notes, which have evolved over the years. Peter Gedling, who then worked for the British Ship Research Association, was a guest lecturer. His clear exposition, and physical insight, are the basis of the sections on the maximum entropy and maximum likelihood methods for estimating spectra. One of the engineers on the first course, John Medhurst, has contributed the case study on measuring ship hull roughness, and Bob Townsin gave us helpful comments on our presentation of this work. We thank them for permission to use their work. We also thank Ann Satow for organizing the courses so efficiently, Richard Carter for valuable library support, and Diane Sevenoaks for all her secretarial work.
