This text considers the problem of the dynamic fluid-structure interaction between a finite elastic structure and the acoustic field in an unbounded fluid-filled exterior domain. The exterior acoustic field is modelled through a boundary integral equation over the structure surface. However, the classical boundary integral equation formulations of this problem either have no solutions or do not have unique solutions at certain characteristic frequencies (which depend on the surface geometry) and it is necessary to employ modified boundary integral equation formulations which are valid for all frequencies. The particular approach adopted here involves an arbitrary coupling parameter and the e...
These colorful stories weave historical characters with fictional situations to create entertaining images of the American West.
Do you "know" that posh comes from an acronym meaning "port out, starboard home"? That "the whole nine yards" comes from (pick one) the length of a WWII gunner's belt; the amount of fabric needed to make a kilt; a sarcastic football expression? That Chicago is called "The Windy City" because of the bloviating habits of its politicians, and not the breeze off the lake? If so, you need this book. David Wilton debunks the most persistently wrong word histories, and gives, to the best of our actual knowledge, the real stories behind these perennially mis-etymologized words. In addition, he explains why these wrong stories are created, disseminated, and persist, even after being corrected time an...
