Recent studies by the PI and the Co-PI of this STTR effort have shown that aluminum alloys and stainless steel in Low Cycle Fatigue (LCF) fail upon reaching a critical entropy; claimed to be an intrinsic material property. The critical entropy has been used as damage metric for prediction of remaining useful life (RUL). Also, similar entropic concept has previously been applied to LCF of composite ...

Toyon Research Corporation, together with the University of California, Santa Barbara (UCSB) propose to demonstrate a GPS-denied Local Carrier-based Precision Approach and Landing System (LC-PALS) that enables 3-D position, navigation and time (PNT) for platforms within range of an aircraft carrier equipped with one or more ADEPT-compliant beacons. Unlike the Global Positioning System (GPS), which ...

Thousands of years of evolution have produced the human vision system that computers cannot replicate well. Humans are still unsurpassed in their ability to search for objects in visual scenes. To successfully detect objects in cluttered scenes, the human brain is thought to rely on multiple factors: prior probabilities of object occurrence, global scene statistics and object co-occurrence. Machin ...

Antimicrobial treatment of military textile systems is intended to provide enhanced protection to the Warfighter in the field by preventing colonization of harmful bacteria that cause problems such as odor, dermatitis, impetigo, cellulitis, and other skin irritations. Current treatments can impart antimicrobial functionality to textiles; however, they all possess broad-spectrum antimicrobial activ ...

Spontaneous emission is a quantum mechanical process that represents the main source of phase noise in state-of-the-art semiconductor lasers, limiting their coherence, and their suitability for high-speed communication and sensing applications. This proposal aims to develop ultra-high coherence semiconductor lasers on the Silicon/III-V platform with a quantum linewidth of

The low density of magnesium makes it of interest for the development of advanced materials having high specific strength and stiffness. Current Mg applications, however, are limited by the performance and cost/quality relationships of existing Mg-alloy systems. One approach to obtain improved Mg alloys is through the development of new alloys and/or Mg-based composite materials that are enabled t ...

HYPRES, in collaboration with University of California, Berkeley, proposes to transition superconducting parametric amplifier technology into a robust line of products. In Phase I, we designed a compact package for lumped-element Josephson parametric amplifiers (LJPA) fabricated by our collaborators at MIT Lincoln Laboratory. We have also established the feasibility of digitization of the amplifie ...

ABSTRACT: The sensor system requirements for image based navigation that uses passive millimeter wave imaging radiometry will be established based on existing RelNav and AbsNav algorithms that were demonstrated to work in multi-modal imagery. Existing flight data will be used to simulate the PMMW imagery for these tests. A preliminary design of such a PMMW system will be created. Under Phase-II th ...

ABSTRACT: The overall objective of this project is to develop scalable simulation components that effectively model the meso-scale physics of heterogeneous energetic materials subject to dynamic shock loading including matrix debonding, void collapse, and damage due to crystal to crystal interactions, and bridges the meso-scale to the macro-scale for system scale simulations of the transition to d ...

Rechargeable lithium ion battery systems can provide power throughout the aircraft, including engine or Auxiliary Power Unit (APU) starting, avionics, emergency, and other systems. Because of their high specific energy/power and potential thermal instability, they can present hazards if improperly designed, tested, handled, or stored. To address the thermal safety issue of Li-ion batteries, EIC La ...
