Time correlations in 1D quantum impurity problems
, 1995 We develop in this letter an analytical approach using form- factors to compute time dependent correlations in integrable quantum impurity problems. As an example, we obtain for the first time the frequency dependent conductivity $G(\omega)$ for the ...

Development of an integrated BEM for hot fluid-structure interaction [PDF]
One of the most difficult problems in engine structural component durability analysis is the determination of the temperatures and fluxes in the structural components directly in contact with the hot gas flow path.

Asymptotic analytical methods in fluid mechanics related to drag prediction [PDF]
Some recent theoretical work of a purely analytical nature is described which promises to provide engineering predictions for the important drag-related phenomena of flow in the stall regime. This analytical work deals with rigorous asymptotic studies of
