This is a Phase 2 proposal to develop an instrument to simultaneously measure particle size, velocity, and concentration in applications characterized by a large size range and high particle concentration. The instrument will be based on the Pulse Displacement Technique whose feasibility was demonstrated during Phase 1. Experiments performed during Phase 1 demonstrated a high accuracy in meas ...

The goal of the proposed program is to develop detectors for X-ray fluorescence that have enhanced efficiency and energy resolution for low energy (

As flip-chip bonding becomes the predominant standard in the electronics industry, the increased proximity between dice surfaces and packaging materials will require a significant reduction in the latter's alpha particle activity in order to avoid soft errors. Emission rates at or below 0.001 a/cm2/hr are desirable, which is well below the 0.0050 a/cm2/hr capability of today's best detectors. ...

As ever more of industry and commerce moves onto electronic networks, there is a growing appreciation for the usefulness of expressive general models of enterprise activities, such as design and manufacturing. Ontologies are commitments to formal declarative multi-purpose representations with clear semantics that can serve as a solid foundation for such models. While there has been much work ...

Light scatter has been used to map and size particles on silicon wafers for many years, producing accurate maps of particle position and giving an indication of particle size, but do not reveal any information about particle composition. Today's technology is limited by noise, precluding detection of the smallest particles of interest. Present instruments are not adequate for the next generation ...

Development of efficient spray combustors requires a complete understanding of fundamental phenomena that influence and control the overall spray combustion process. Toward this end, detailed experimental characterization of spray flames is essential. This includes measurement of various fuel droplet parameters such as droplet size, velocity, number density, temperature, composition, and droplet ...

The specific problem addressed by the proposed research is the development of a scanner for storage phosphor plates with significantly better positional and intensity accuracy than the current state of the art. The new scanner will be based on the use of a "scanning head" scanning approach which is more simple, accurate, and stable than the approaches previously used. This results in stable and ...
