The use of enzyme-linked immunosorbent assay (ELISA) to detect contaminants such as solvents, fuels, and pesticides in soil and water samples is now well established. Although ELISA and related methods can facilitate analysis of samples, several washing and separation steps are involved that require 30 to 120 minutes per sample to reach equilibrium. Recently, near infrared fluorescence immunoassa ...

Arca proposes research leading to development of a suite of methodology support products to help meet the need for innovative assurance techniques appropriate for emerging information technologies. The product will consist of a licensable methodology and supporting materials for specifying, building, and evaluating assurance arguments for products and systems based on the capability of security en ...

American health care is in the midst of momentous change. Quality improvement principles are being used increasingly to enhance productivity and efficiency of health care delivery and to help contain costs. In producing patient outcomes and resource utilization measures, it is vital to control appropriately for case mix (i.e., differences in patients due, e.g., to illness severity) in the predicti ...

We will develop technology, termed a Ruggedized Wind Measurement System (RWMS), to measure directly extreme winds with high space and time resolution, focusing on the winds that occur beneath hurricanes at land fall. This development effort will include design, fabrication of two prototype RWMS units, and a series of proof-of-concept demonstrations in strong mountain-induced downslope and severe t ...

The contractor proposes a new approach to underwater imaging that directly converts a two-dimmensional acoustic pressure wave into an electronic requirements fo convential piezo-element arrays. The imager relies on the piezo-birefringent properties of a nematic liquid crystal panel that serves as both sensor and display. The capability of nematic liquid crystals has been established and publishe ...

The objective of the proposed program is to address the high service costs of the current U.S. Navy fleet of aircraft by developing a distributed optical fiber sensor system that will help reduce the costs associated with corrosion damage and extend the lifetime of existing aircraft. Annual corrosion of Navy metallic structures has been estimated as high as $1 billion. Additional costs aris ...

In this proposal, we describe a novel approach for realizing a parallel, nonmechical, read/write interconnection for angle-multiplexed three-dimensional (3-D) optical memories. Our concept represents a significant first step required toward taking this critical memory technology from the laboratory and inserting it into operational systems. The concept utilizes novel optomechanical packaging and ...

We propose to characterize the early stage of consolidation of non-spherical powders to further the development of process models to enable simulation of powder metallurgy manufacturing for the consumer market, especially the automotive industry. Typically, spherical powders with a narrow size distribution are used for aerospace applications, while low-cost powders with irregular shapes and a wide ...

This effort will develop an HLA compliant representation of non-visual stimuli with the intention of utilizing the models developed in Phase I effort to provide data for "human" mannequin stimulation in Phase II. The Phase II goal is to have the mannequin respon in a physiologically realistic manner to the non-visual stimuli data that will be passed to it over a network and via an interface. Suc ...
