In this proposal, AlphaSense, Inc. (AI) and the Oklahoma State University (OKState) detail the development of a novel Cavity Enhanced Terahertz Absorption Spectrometer (CETAS). Key innovations of the proposed system include: a) the use of a small Whispering- Gallery- Mode (WGM) cavity to achieve very long pathlength; and b) the integration of the WGM cavity with the conventional pulsed and continu ...

In this proposal, AlphaSense, Inc. (AI) and the University of Michigan (UM) detail the development of a compact, portable, and low cost in-process weld defects detection system. Key innovations of the proposed system include: a) weld defects monitoring based on plasma emission characteristics; b) use the electron temperature of the plasma as an indicator of the weld quality, c) use multiple plasma ...

Automated assessment and forecasting of aircraft health status has become a prime requirement for safety, reliability, and cost streamlining for 21st century’s aviation sector. Presently, a variety of flight data, functionality, performance, and maintenance information are being collected and some are stored in databases, but an integrated health management (HM) system that utilizes all these in ...

Topic Synopsis: Current aircraft disposition tools are not designed to take advantage of predictive prognostic information that will be available on new systems such as the F-35 PHM system or the proposed Maintenance and Monitoring system for the E-2D Hawkeye. The central challenges in this topic are to (1) develop automated reasoner technologies to distill large volumes of PHM data into actionabl ...

The objective of this proposal is to demonstrate the feasibility of developing advanced battery chemistries that provide batteries operate safely at specific energies higher than 100 Wh/kg, energy densities over 600 Wh/l. The olivine-type phosphate cathodes are attractive. The stable nature of the olivine-type structure having a PO43− polyanion with a strong P–O covalent bond provides not only ...

Simulations, LLC, a privately held small-business engineering company, and team members DR-Technology, the U.S. Army Research Laboratory (ARL) and Douglas Elder, proposes to develop the material and fabrication methodologies to produce a lightweight, high-strength, low-cost composite sabot based on innovative configurations. Simulations will springboard from: (1) the current ONR Projectile IPT sa ...

Lift and drag characteristics of arbitray, irregularly shaped fragments will be computed using a combination of Reynolds averaged Navier-Stokes (RANS) equations and the Large-Eddy Simulation (LES) method. Cartesian meshes will be generated for the shapes, and accurate lift and drag characteristics will be post-processed using the simulation data bases. Outputs will be in the form of tables that ca ...

DESCRIPTION (provided by applicant): The hallmark of Alzheimer's disease (AD) is the presence in brain of plaques, which are complex extracellular lesions composed of a central deposition of 2-amyloid peptide. Genetic, neuropathological and biochemical evi dence have shown that these deposits play an important role in the pathogenesis of AD. We have confirmed the hypothesis that Alzheimer's diseas ...

Sources and detectors in the range of 300-10,000 GHz pose a unique challenge to implementation as semiconductor devices. Transistor oscillators do not have the bandwidth to generate these frequencies/wavelengths and optical devices do not have energy gaps small enough to provide effective stimulated emission. Intersubband transitions do provide these energies. The quantum cascade structure (QCL) ...

ANP Technologies proposes to integrate a commercially available air sample concentrator from ICx MesoSystems with our automated detection instrument that uses the NIDS® multiplexed assays and NIDS® Auto-Reader (AR) device. A trigger device may also be incorporated into the final system, which might better enable the system to serve as a remote monitor of air streams. The proposed effort will b ...
