Analysis of chemical samples in the field and in confined areas has many advantages over laboratory analysis. Laboratory analyses can be slow, involve increased expense, lead to additional waste generation and disposal problems, and may introduce errors due to sample degradation or mishandling. In situ analysis mitigates all of these problems. The specific aim of this project is the development of ...

With the ongoing involvement of computers in all facets of modern society, both private and public organizations increasingly rely on computer networks to support key portions of their critical infrastructure. Consequently, those networks contain increasingly more sensitive information, making them prime targets for would-be attackers. The goal of a typical intrusion detection system (IDS) is to p ...

Lithium-based batteries promise excellent performance, although they require careful management to avoid personnel injury and equipment damage. Consequently, there is extreme interest in developing accurate Battery Management Systems (BMS) to take advantage of the positive attributes of lithium-based chemistries without sacrificing flexibility and safety. However, the lack of proper BMS standardiz ...

Weldments that join plates of aluminum or steel combat vehicle hulls can be the lowest strength area of the structure and thus provide a decreased level of ballistic protection. To avoid welds, seamless hulls could be formed from thick plate if a suitable manufacturing process is developed. Corvid Technologies, teamed with Concurrent Technologies Corporation (CTC) performed a series of modeling, s ...

THE TECHNIQUE EMPLOYS NEWLY-DEVELOPED FAST SCANNING ELECTRO-OPTICAL SENSORS AND FAST SPECIALMICROPROCESSOR SUBSYSTEMS. THE WORKPLAN INCLUDES DESIGN AND EVALUATION OF THE APPROPRIATE ALGORITHMS, SCALED EXPERIMENTS USING A ...

Applied Quantum Technologies proposes the development of a snapshot Raman spectral imager for chemical imaging applications with a 1-5 meter standoff. Standoff chemical imaging methods are typically point-based, making scan times impractical for situations where a wide area needs to be surveyed. The high spectral resolution needed to take advantage of the specificity of Raman spectroscopy limits t ...

The technology, theory and fabrication of metamaterials have seen impressive progress in the last few years, and various applied fields have benefited from the flexibility of electromagnetic response that metamaterials provide at microwaves, infrared (IR) and/or optical frequencies. Negative-refractive and zero-permittivity metamaterials have been proposed for breakthrough novel applications in m ...

Current high-throughput platforms rely on labeled substrates that produce detectable spectroscopic signals upon reaction for monitoring enzyme catalytic activity. Add to that the high price tag for these instruments, ranging from several hundred thousand to millions of dollars, and there is a clear need for alternate solutions for a label-free, low-cost, high-throughput enzyme screening platform. ...

Current drug discovery and development efforts are severely limited by expensive animal trials and oversimplified in vitro models. Results obtained from in vitro models are not predictive of in vivo toxicity owing to significant difference from the in vivo physiological conditions. In this context, we propose to develop and demonstrate a novel microfluidic device that reproduces the physiological ...

Polarization imaging holds promise for providing significant improvements in contrast in a number of target detection and discrimination applications. In several recent development efforts, it has been demonstrated that manmade objects have a significantly stronger polarization signal than natural backgrounds resulting in good contrast that complements the conventionally imaged infrared signature. ...
