ABSTRACT: We propose to develop a light weight, compact, vibration-less and micro-scale cooler for space-mission conditions based on optical refrigeration using an all-fiber approach. Specifically, we will use a Tm+3-doped fiber laser to pump Tm+3-doped glass fibers, which provide the cooling action on the affixed heat source. The cooling fiber is attached to the heating sample e.g., EO-IR detect ...

ABSTRACT: Traditional multidisciplinary solvers function by solving the individual governing equations on computer clusters. In the case of aero-elastic Fluid-Structures Interaction (FSI) simulations, individual solvers have disparate requirements for optimal performance. CFD codes use iterative schemes and distributed memory, while CSD codes, use direct linear-solvers and utilize shared memory t ...

ABSTRACT: This STTR Phase I project addresses exploit attempts being mounted against applications code and modules with vulnerabilities that need to be protected. The team's strategy is to"blacken"or isolate applications and the inter, and intra communications paths between them and the lnternet using innovative algorithms developed by Embry-Riddle Aeronautical University (ERAU). We plan to ...

ABSTRACT: The key objective of the proposal is to develop sophisticated, graphical user interface driven software tools built on fully microscopic physics to design, guide and provide feedback on growth, fabrication and evaluation of semiconductor structures that provide optical gain in the critical 2.4-4 micron wavelength window. Existing technologies are severely limited by low gain, high losse ...

ABSTRACT: We are experiencing grand challenges to ensure that cyberspace resources and services can effectively tolerate epidemic-style cybperattacks, and manage automatically its resources and services. Currently, there are no effective commercial technologies to secure and protect cyberspace resources and services; they are mainly labor intensive (e.g., patch update), signature based, and not f ...

Pikewerks'Protection for Industrial and Environmental Controls from Exploitation, or PIECE, will be a cross-platform suite of capabilities providing anti-exploitation and anti-reconnaissance for Industrial Control Systems. PIECE will provide a suite of capabilities for Windows, Linux, VxWorks, and legacy devices that ensure survivability of critical infrastructure equipment. Anti-exploitation ...

The U.S. Air Force is developing a catalytic thruster for advanced high density-specific impulse green monopropellants. The temperature and pressure generated in a green monopropellant thruster is much higher than with conventional hydrazine monopropellant, resulting in degradation of the catalyst. Therefore, developing and applying a model for predicting catalyst degradation and thruster performa ...

Current station keeping equipment (SKE) relies on radio waves for formation flying. A significant limitation of conventional SKE signals is that they are detectable at long distances by adversaries. Passive detection schemes that employ infrared and thermal cameras, electro-optic and acoustic sensors are of interest for future SKE upgrades although they lack the capability to provide sufficiently ...

In this effort, we will couple the energy of focused microwave bursts into the air and onto surfaces by first forming a laser plasma. The presence of the laser plasma allows much lower microwave intensities to couple their energy to the laser-pre-ionized surface or air-volume, allowing more efficient energy-transfer and the use of lower-power microwave systems to achieve the desired effect. We w ...

ABSTRACT: Nanomaterials promise to bring critical advancements to technologies and products affecting multiple DoD mission areas. A major obstacle to realizing the strategic benefits of nanomaterials is the absence of computational risk assessment tools that allow nanomaterial developers to integrate and translate dose-response data and hazard rankings across in vitro and in vivo systems, between ...
