    Notes: Some recent results for the force on a translating rigid three-dimensional body in incompressible flow, in which the integration is over the vorticity field rather than surface pressure, are interpreted from a point of view that distinguishes changes of fluid impulse directly attributable to the vorticity field from those due to its image system in the body. An expression is first derived geometrically for a sphere in inviscid fluid; the flow is taken to consist of discrete vortex loops whose change in impulse, and that of the image system in the sphere, are calculated via their projected areas. As an example, the force on a sphere due to an infinite line vortex is calculated exactly. To generalize the geometrical derivation to bodies of any shape, a reciprocal theorem is proved concerning the impulse of the image system of a dipole. This yields the inviscid form of a result derived mathematically by Howe [J. Fluid Mech. 206, 131 (1989)]. Physical interpretations of the various terms in Howe's expression are offered, and the relationship to a very similar independent result by Chang [Proc. R. Soc. London Ser. A 437, 517 (1992)] is discussed. © 1996 American Institute of Physics.

    Notes: Speech databases on Danish, Dutch, English, French, German and Italian are being set up as part of an Esprit-funded project, ‘Speech Assessment Methods’ (SAM), which is concerned with the establishment of standardized assessment methods for automatic speech recognition devices. An important aspect of this work is the devising of a standard set of conventions for the machine-readable phonetic transcription of these languages. This matter was discussed at a two-day meeting in London devoted to aspects of the organization of speech databases, which was attended by participants from SAM Partners in the five currently participating countries (Denmark, France, Italy, Netherlands, United Kingdom), together with representatives from the German Federal Republic. Participants agreed that a compromise based on the three existing multilingual proposals could be achieved: its broad outlines were agreed, while the elaboration of detail was left to the present author and this report.
