With the objective of ultimately providing tools and technologies for facilitating logical connectivity for manufacturing applications in an NII environment, this proposal involves research in the ares of: agent-based mediators, shared ontologies, conversion libraries, scalability, and automated reading of information from paper and other traditional media.

Microscopic measurement of surface topography is a continuing need in microfabrication technology and materials research. The aim of this research is to adapt the scanning electron microscope (SEM) to the quantitative measurement of a wide range of surface structures. The SEM is a widely used measurement tool in materials science and semiconductor fabrication. The SEM's strength is that it prov ...

Soaking and co-crystallization experiments for studying the binding of potential drugs with proteins of known structure are a significant research function of crystallographic labs in pharmaceutical companies. Such experiments have two overriding characteristics: (a) the experiments are repetitive, and therefore become routine, and (b) numerous experiments are performed to acquire the desired in ...

The development of a Fourier transform spectrometer with a minimum number of moving parts (or more ideally no moving parts - the so-called stationary spectrometer) has been the subject of considerable research and development. Recent work on a birefringence based system has resulted in the introduction of a commercial version of the system. While a significant step toward the goal of a practical ...

Currently, advanced tools for modeling injection modeling of thermoplastics and predicting formed part dimensional stability and residual stress content use the static bulk modulus of the polymer at the temperatures and pressures associated with the molding process. The short cycle times associated with injection molding, however, could be more accurately modeled if dynamic bulk modulus data were ...

The near-field scanning optical microscope can supply information on the shape and electrical properties of surfaces with nanometer resolution. The quantitative interpretation of images is difficult because of the difficulty of electromagnetic field solutions in the near-field limit. We propose to supply software to aid in this analysis. The finite-element programs generate two and three-dimension ...

Critical issues associated with the design of a rugged, compact "real time" sampling system using photoconductive switches as the signal generator and sample will be investigated. The design concept is based upon an optoelectronic equivalent time sampling principle developed by the Principal Investigator. It involves first the phase locking of the temporal waveform to be measured to the optical pu ...
