For efficiency reasons, Machine Translation systems are generally designed to eliminate ambiguities as early as possible even if delaying the decision would make a more informed choice possible. This paper takes the contrary view, arguing that essentially all choices should be deferred so that large numbers of competing translations will be produced in typical cases. Representing all the data s...

Charts constitute a natural uniform architecture for parsing and generation provided string position is replaced by a notion more appropriate to logical forms and that measures are taken to curtail generation paths containing semantically incomplete phrases.

Nowadays, Radar systems have many applications and radar imaging is one of the most important of these applications. Inverse Synthetic Aperture Radar (ISAR) is used to form an image from moving targets. Conventional methods use Fourier transform to retrieve Doppler information. However, because of maneuvering of the target, the Doppler spectrum becomes time-varying and the image is blurred. Joi...
