The primary objective of this proposed work is to develop a method of producing integrally stiffened, complex shaped monolithic structural components in high strength aluminum alloys at a lower cost and lighter weight than equivalent conventional built-up assemblies. In Phase I the feasibility of attaining this objective will be demonstrated by conducting a series of subscale experiments based upo ...

We propose a method of generating x-rays that will combine high instantaneous output of rotating-anode x-ray tubes with continuous cooling rates as great or greater than fixed-anode tubes. This combination can be achieved in a mechanically simple way, and will reduce spot wobble without vacuum seals, vacuum bearings, deflecting field, or conventional cathodes, by either thermionic or photoemission ...

The ability of subjects to localize and identify each member of a set of acoustic signals will be measured. The acoustic signals will be presented in random order at several locations in auditory space, also chosen randomly. The acoustic signals are constructed to maximize the cues they present for localization and identification in that they contain a wide range of frequencies and timing informat ...
