We propose to develop a computer based system for the online analysis of bio-behavioral signals associated with momentary loss of alertness. We will continue our development of bio-behavioral measures indicative of lapses in alertness. Our system will use only measures that can be obtained without attaching sensors to the operator. We will concentrate on monitoring the oculomotor system using came ...

Highly fluorinated, nanoscaled polymers were developed in a Phase I program (Contract No. W81XWH-04-C-0132) as an oxygen-carrying treatment for hemorrhagic shock in battlefield environments. These were highly soluble in water and buffered electrolyte solution (up to roughly 50% weight/volume) and were thermally stable up to 167 °C. Mixing the polymers with dilute canine blood significantly enhanc ...

Successful advanced Naval ship design must be based on integrating multiple cross-functional systems. Future Naval systems will require innovation and a systematic integration in order to achieve increasingly demanding mission profiles in a cost effective manner. Since a large amount of the design cost (up to 80%) is locked during the conceptual phase, it is important to include both the traditi ...

An innovative, high-speed electromagnetic-wave-detection system based on broadband, non-intrusive, miniaturized electro-optic (EO), magneto-optic (MO), and electro-optic voltage (EOV) sensors will be developed for evaluating the effects that pulsed electromagnetic (EM) waves have on specific components of electronic systems. The suite of optically-interrogated sensors, which may be positioned with ...

An innovative, optically-interrogated test instrument, based on broadband, non-intrusive, miniaturized electro-optic (EO), magneto-optic (MO), and electro-optic voltage (EOV) sensors, will be developed for evaluating the operation of, and the electromagne

Previous studies have shown that superhydrophobic surfaces have skin-friction drag reducing properties in the laminar flow region, but not in the turbulent flow region. The drag reducing properties of superhydrophobic surfaces are recognized to result from air voids trapped in the surface, and the apparent lack of effectiveness in the turbulent flow region could result from: (1) lack of robust air ...

We propose to prove the feasibility of using time domain terahertz (THz) non destructive evaluation (NDE) to inspect turbine blade thermal barrier coatings (TBC). High speed, non contact THz inspection will be useful both during the manufacturing process, during maintaince, and during recoating. Low thermal conductivity ceramic coatings that are deposited on Ni-alloy turbine-engine blades to pr ...

At present, turbine NDE is typically a time consuming collection of inspections that includes manual testing of holes and channels for blockages, multiple flow tests and various inspection technologies such as ultrasound, eddy current and radiography. Thermography has also become a widely method used to perform various inspections. However, many of thermographic inspections require different equ ...

Chemical sensing requires a compact, room temperature laser operating over the mid-IR. Omni Sciences, Inc.’s (OSI’s) Mid-Infra-Red FIber Laser (MIRFIL) will generate continuous light over 1 to 5 microns with an average output >1W. OSI has demonstrated a
