Asthma is a major health problem facing the US, and the rest of the world's population. What is needed, both for the military as well as the civilian population, are rapid screening tests that would reduce the demand for intensive examinations. Exhaled breath monitoring is thus a new tool in the non-invasive assessment of airway inflammation which may be present before the onset of airway obstruct ...

ACX proposes an alternate approach to damping for extreme environments, which uses an electrically shunted, surface mounted, smart material. This shunting approach has been most widely used in less extreme environments in conjunction with piezoceramic materials. The smart material is bonded to the surface of the target structure, in this case a part inside an aircraft engine. Stress on the part ...

Active Control eXperts, (ACX) Inc. proposes to design, fabricate, and demonstrate a novel hybrid vibration ccntrol actuator system capable of very precise, controllable motion. This system will combine the advantages of a capacitive actuator with feedback control capability. This system will possess the force and stroke characteristics of a small hydraulic device and the bandwidth of electric moto ...

In many structures with vibration problems, the nature of the problem is uncertain, or varies over time. Thus it is not possible 'a priori to design a linear, time-invariant, (LTI) feedback control law which is guaranteed to meet performance, or possibly even stability requirements over the entire operating range. These applications require an intelligent control system which can adapt to the ch ...

This proposal describes the development of an instrument based on laser-induced breakdown spectroscopy (LIBS) for the detection of lead in paint and soil that will have both military and commercial applications. The Phase I instrument will be similar to multi-species, portable LIBS instruments built by Dr. David Cremers at Los Alamos National Laboratory that utilize a spectrograph/charge coupled ...

A unique approach is proposed for the effective rejection of cochannel, but otherwise arbitrary, jamming and other interference in GPS reception. The approach is based on a method of processing a multiplicity of signals sharing the same time-frequency and polarization space, in such a way as to favor a bona fide GPS signal over the others present (jamming, spoofing, multipath, atmospherics or oth ...

The primary objective of this proposal is to develop an understanding from first principles of the macroscopic particle force equation arising from the microscopic particle and field interaction dynamics and to incorporate those effects in a self-consistent state-space (rate equation) PIC calculation. Effective current and charge density time-domain equation models will ...
