An emerging consensus in engineering holds that aleatory uncertainty should be propagated by traditional methods of probability theory but that epistemic uncertainty may require methods that do not confuse incertitude with variability by requiring every possibility be associated with a probability that it occurs. Therefore, although Monte Carlo shells that re-run calculations many times while var ...

This Phase I STTR proposal will demonstrate nanostructured “metal-black” coatings to enhance absorption by thin film solar cells. The problem is that silicon has low absorption due to its indirect gap. The opportunity is that nano-scale metallic scattering centers increase the effective optical path length and enhance the solar electric-field strength in thin-film solar cells, leading to more ...

DESCRIPTION (provided by applicant): Bacterial Vaginosis (BV) is an exceptionally common vaginal condition in which robust lactobacillus microflora in the vagina is replaced by a dense polymicrobial overgrowth. At any given time, about 1 in 3 women in the U.S. have BV; half are asymptomatic, and most women with symptomatic BV have only mild symptoms (increased discharge with a fishy smell). Despit ...

he Storable Clean Ethane-ethylene Nitrous Engine (SCENE) is a proposed technology designed to provide upper stages and spacecraft with non-toxic, liquid, non-cryogenic, high-performance propulsion with an Isp on the order of 300 seconds. The propellant components are stored as liquids under their saturated vapor pressures. With the SCENE, nitrous oxide is used as an autogenously pressurized oxidiz ...

Impact Technologies and Montana State University propose to develop a Dynamic Prognostic and Health Management (PHM) modeling capability and related test, validation, and support toolsets that will enable standardized approaches to model representation, information exchange, and PHM system support, providing for improved integration, interoperability and reuse of developed and emerging capabilitie ...

Emerald Education Systems has developed an online continuing professional education learning system that targets low vision rehabilitation service providers. This CE learning system has three components: 1) a set of coordinated in depth online courses that provide a broad and deep foundation of knowledge on low vision rehabilitation that is delivered using a didactic approach at a learner-controll ...

Impact Technologies, in collaboration with the Georgia Institute of Technology and its industrial partners, proposes to develop and demonstrate innovative technologies to integrate anomaly detection and failure prognosis algorithms into automated fault mitigation strategies for advanced aircraft controls. Traditional reactive fault tolerant control approaches fail to provide optimal fault mitigati ...

The proposed research program focuses on design, fabrication, and characterization of quantum-dot infrared photodetectors (QDIPs) which features bias-tunable parameters, including the spectral response, optical gain, and operating time. Wide variations of detector parameters can be realized through the bias-tunable potential barriers surrounding quantum dots. Changes in bias will transform the ba ...

We propose to develop a commercial weakly ionized plasma modeling capability based off of Tech-X’s high energy density plasma fluid code TxFluids. The new additions will be able to be used to model hypersonic vehicle physics including shock waves, plasma chemistry and innovative techniques for blackout mitigation and hypersonic vehicle control through the application of electric and/or magnetic ...

Accurate and timely surveillance of objects in the near-Earth space environment is becoming increasingly critical to US national security. One of the main difficulties in this domain is efficiently and accurately modeling trajectories of the vast number of objects in orbit around the Earth. The orbital trajectory of a single object is typically modeled as a second-order system of equations which ...
