This proposal is directed at creating discontinuous unidirectional composite from continuous unidirectional prepreg. The process, Selectively-Discontinuous-Fiber (SDF), introduces micro-cuts in preimpregnated unidirectional materials at specified locations. This process will allow unidirectional composite prepreg to be used for the fabrication of complex-compound components that have be ...

Current fire fighting training methods are possibly lacking maximum effectiveness due to increasing safety and environmental regulation. Additionally, performance measurement in large classes becomes difficult unless trainees have identical training scenarios and evaluations. This proposal details the analysis of current training methods and subsequent emulation of them using virtual reality (VR ...

Measuring temperature in specimens being heated by electromagnetic energy requires the use of special probes. The temperature probes must be specially designed to minimize electromagnetic field perturbations. Several types of non-perturbing temperature measurement probes have been investigated and developed. Many employ optical fibers rather than electrical conductors to avoid the e ...

The Dynamic Environment Simulator (DES) at Armstrong Laboratory will be a useful tool for crew member training and human factors research for future high performance aircraft. To make the best use of the DES, this proposal presents a plan for creating a software tool that simulates the operation of the centrifuge. The software would enable scientists to specify a time history of desired crew mem ...

The Head-Spine Model (HSM) is a three-dimensional, discrete element mathematical model and software program that describes the kinematics and loads of the head-neck spine structure due to high impact accelerations. The proposed Phase I development program represents an effort to rehost the FORTRAN software from a Unix workstation environment to an IBM PC-Compatible MS-DOS environment, to study th ...

Having been recently discovered, otacoustic emission (OAEs) are low-level sounds produced by the inner ear as part of the normal hearing process. There is great potential in using reliably measured OAE to provide a quick, inexpensive and non-intrusive assessment of hearing functional levels and detection of early temporal damage to the hearing function. To further explore this potential, an adva ...

The application of electric fields in the presence of flame fronts has demonstrated a definite effect upon the progression of the flame front. The application of electrogasdynamic (EGD) technology toward influencing combustion processes shall be examined in addition to electromagnetic fields. No environmentally detrimental compounds ar utilized or released with this process.

In Phase I of this Small Business Innovation Research program we propose to investigate the fabrication of Si quantum well structures for optoelectronic applications, employing Al2O3 (sapphire) as the barrier material. The program will investigate the growth of Al2O3 epilayers on Si, Si epilayers on Al2O3, and elementary Si/Al2O3 multilayers. While Si and Al2O3 have differing crystal s ...
