Few-cycle mid-infrared lasers are in high demand for a variety of practical applications including remote sensing of chemical and biological species. NP Photonics and the University of Arizona propose to develop a wavelength tunable and power-scalable optical parametric laser system covering 8-10 micron and capable of producing collimated few-cycle pulses with pulse energy > 100 microjoules. A ful ...

ABSTRACT: We will develop a multiscale molecular dynamics/material point method (MD/MPM) methodology for determining the response of PBXs to a wide range of loading conditions as a function of mesoscale structure with emphasis on accurate representation of interfacial physics. The initial material of choice will be HMX + DOA plasticized HTPB binder. Velocity-dependent grain-grain and viscoelastic ...

A chemical threat agent mode of action is often initiated through a selective interaction with a biological molecule or structure. The agent binding mimics normal cellular processes, but then overruns natural control mechanisms leading to toxic and lethal effects. The binding is used as a basis for sensing the agent. We are exploiting the native binding mechanism, designing and producing prototype ...

The DoD uses flexible fuel bladders in multiple air, ground, and sea vehicles because: 1) they easily fit into almost any space, 2) they are corrosion proof, and can often be self-sealing and explosion proof, 3) they allow for customized placement of fittings and connection points, 4) they collapse as they empty, thereby eliminating the need for venting and minimizing fuel sloshing and its associa ...

ABSTRACT:A new algorithm, the Daylight Object Restoration Algorithm (DORA), has been developed. DORA includes a novel implementation of the multi-frame blind deconvolution image restoration concept which recovers high-quality object estimates from sequences of degraded images. DORA removes the effects of atmospheric aberration in images recorded at ground-based telescopes, and is designed to opera ...

To induce controlled defects in wire feed E-Beam additive manufacturing for making NDT standards, MER will work with Applied Optimization (AO) to develop a Physics based ICMSE based process model of defect formation which captures the influence of closed loop control parameters of power, build temperature, wire feed rate and deposition path. This model will be verified by experiment on a closed lo ...

Spider silk is one of the strongest yet still elastic natural materials to be formed into fibers. The ability to utilize these proteins in next generation clothing and cordage represents a leap forward in textile technology. Unfortunately the farming of spiders necessary to generate natural fibers is difficult and costly. As a result the expression of the proteins from other hosts is warranted. Th ...

In this Phase I proposal, we describe the design of a radiant-heating system enabled by the Nanoxene electrothermal coating technology recently invented by Life-E. We will demonstrate the feasibility of fabricating this system as radiant-floor heating technology for expeditionary shelters. The new radiant-heating system has an accordion-style planar sheet structure, powered by a three-phase AC inp ...

A new approach to manufacturing is needed to streamline the logistics of maintaining legacy aircraft. Recently, Advanced Ceramics Manufacturing (ACM) developed a water soluble tooling technology (FastCore) that can reduce the cost of Fiber Reinforced Plastics (FRP) composite components. The FastCore family of products allows ACM to rapidly create water soluble mandrels for composite manufacturer ...

ABSTRACT: The research team will specify a data model, database, and preliminary architecture for the Prognostic Scheduling system. A proof-of-concept software demonstration will be developed, including support for database, data mining, data fusion, and prognostic scheduling software capabilities. The data mining capabilities will be deployed to a "Big Data" environment to improve its computation ...
