Ganuna (7)-ray lenses are an advanced technology currently under development at Argonne National Laboratory for arms control application. The purpose of this proposal is to address whether y-ray lens technology can enable an improved system for imaging radioactive isotopes in patients. In nuclear medicine, it is often desirable to generate a y-ray image that shows the exact areas where an emitting ...

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 ...

The proposed project consists of developing a software package which can be used in the development of site plans at facilities where high explosives are stored or handled. The software will be a public release product and is intended for approval by the DDESB. Site plans developed under proper application of the software will be in compliance with explosive safety siting standards in DOD 6055.9. ...

1We are proposing a computerized tomographic (CT) dimensional measurement system that will remedy two of the major problems experienced by current methods: the distortions caused by CT artifacts, and the blurring caused by the system point - spread function (PSF). The distortions resulting from data nonlinearity will be corrected by a calibration process acting upon the x-ray data. The blurring er ...

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 ...

An algorithmic solution to the compression of continuous vidoe images containing Navy environmental data such as a weather briefing is proposed. The technique described is an extension to the multiresolutional algorithms used presently for compression, and particularly an extension of the wavelet transform. A company developed technique image analysis system will be coupled to the transform theory ...

The idea of automated processing of imagery has been the desire of technology since devices to collect volumes of images have been in operation. In this proposal we discuss the relative merits of automated image processing in the spatial and transform domain. We suggest that with the development of wavelets and vector quantization (VQ) used in compression, the possibility exists to use the values ...
