Memoriam.

George W. Housner, Carl F Braun Professor of Engineering, emeritus, died after a short illness on 10 November 2008, just a few weeks before his 98th birthday. He was in the retirement home in Pasadena where he had lived for several years. For all of us who knew George, this marked the end of an era. Few people have guided and nurtured a field the way George led earthquake engineering over a per...

Spectral changes in the tom-tom related to striking force

This study has investigated the question how the radiated spectra of a tom-tom changes with striking force. Five tom-toms of different size were recorded at four dynamic levels (pp, mp, mf and ff) and their averaged spectra analysed. It was observed that the number of modes excited increase with playing strength, seen in the radiated spectra as a characteristic change in slope for higher freque...

In Memoriam: Mark Everingham

MARK EVERINGHAM was a brilliant colleague. You may have been aware of him at conferences where he asked penetrating questions that could crystallize a key aspect of a paper. In conversation with him you might have been stunned by a new connection he made between areas of research or to a crucial related work. These questions and observations were a reflection of his very broad knowledge and dee...
