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 ...

We propose a 6 month program during which we will develop and demonstrate an approach for generating well-characterized atomic and molecular beams of metastable species. Such beam sources are necessary for the microelectronics and plasma processing industries because they would provide a valuable tool required to establish a solid database of plasma-related collision processes. This improved and e ...

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 ...

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 ...

The research proposed herein in intended to solve two problems, namely (1) to define a specification framework for access control policies that enables policy composition for both centralized and distributed systems in a precise and systematic manner, and (2) to explore the impact of different security architectures on policy composition. Although most commercial systems support applications that ...

A combustion environment can be described by a characteristic fuel-to-air ratio normalized by the stoichiometric fuel-to-air ratio, otherwise defined as an equivalence ratio, _. The equivalence ratio is used extensively in a wide range of combustion fields from fundamental flame studies, to full-scale fire testing, to power plant operations. There have been basically two methods for calculating ...

This proposal describes a new research program to be established at the small business Still Sciences, LLC, in collaboration with Department of Physics of Oklahoma State University. The overall goal is to develop and commercialize an all-optical dosimetry system for industrial radiation processing based on a novel Pulsed Optically Stimulated Luminescence readout technique and a new Al2O3 material ...

The feasiblity of developing a PC based, pulsed ultrasonic test system for the economical and reliable testing of aluminum cylinders for sustained load cracking is addressed. A system consisting of a host PC, ultrasonic pulser/receiver and data acquisition hardware, control and analysis software, and transducer fixture for accurate positioning is proposed. In addition to the system development, ...
