Luna will team with Dr. John Bowers of UCSB to continue development of an Optical Frequency Domain Reflectometry (OFDR) system-on-chip using heterogeneous silicon photonics to enable a minimal weight structural health monitoring system. This system-on-chip will be the building block for distributed sensing interrogation systems that are the size of a deck of playing cards. This lightweight, rugged ...

Thegoal is to develop asoftwaretool that implementsa novelapproach applicableto fitgeneral pharmacologic, toxicology, or other biomedical data, that mayexhibita non-monotonic dose-responserelationship for which thecurrent parametricmodels fail. Thesoftwareexplores dose-responserelationships using both monotonicand non-monotonicmodels,and estimates theassociated doseresponsecurves,which can further ...

The broader impact/commercial potential of this Small Business Technology Transfer (STTR) Phase II project is the development of software to help bioscientists analyze more tissue in less time and with higher accuracy and reproducibility. Currently, stereology studies require a trained technician to sit before a computer screen, making tedious manual counts (clicks) on hundreds to thousands of mic ...

Cost-effective and power-efficient radiation tolerant semiconductors are needed in various harsh environments, such as particle detectors, communication satellites, high-altitude avionics and medical imagining equipment. These include amplifiers, voltage regulators, analog-to-digital converters (ADCs) and digital logic circuitry. However, radiation-tolerant high-speed ADCs currently cost more than ...

There are an estimated 1.7 million oil and gas wells in the United States, 771,000 of these are considered marginal producers. Combined they make up 11.3% of the US oil production and 8.3% of the US gas production. In that last 10 years, over 131,000 of these oil wells and 48,000 gas wells have been plugged and abandoned. Most of these wells suffer from paraffin plugging problems. The only way to ...

Indium tin oxide (ITO) films are currently the most widely used transparent conductor in optoelectronic applications. However, ITO suffers from several major technological and economic limitations for large area applications such as inadequate performance, high cost, and brittleness. The primary objective of this Small Business Technology Transfer (STTR) Phase I/Phase II project is to develop the ...

Nuclear fusion has great potential for supplying global energy needs with a clean, abundant energy source. Advanced superconducting magnets will be used to contain the plasma at the center of the reactor. To operate these magnets, new sensors are needed to monitor the superconductors in real-time to detect the signs that the superconductor may quench (lose superconducting properties), so that corr ...

Frequency selective surfaces (FSSs) are periodic arrays of conductive elements/patches that cause a particular reflection response when illuminated with high frequency electromagnetic energy. nbsp;These arrays arenbsp;used for high frequency filters and in antenna applications.nbsp; We propose to use FSSs as multi-functional sensors. nbsp;FSS sensors are unpowered, low-profile (thin), wireless and ...

The proposed Phase II supports completion of the RINGS science missions on ISS using SVGS as real-time sensor for the EMFF maneuver. During Phase I, SVGS-based navigation of RINGS was developed and tested on a 3DOF ground-based platform, and mechanical and electrical integration of RINGS with the free-flying robotic platforms on ISS (Astrobee) was designed in detail. SVGS was deployed and tested o ...

This NASA sponsored STTR project will investigate methods for close-out of large, liquid rocket engine, nickel or stainless steel nozzle, coolant channels utilizing robotic laser and pulsed-arc additive manufacturing (AM)methods. Structural jacket to coolant channel land area interface strength will be quantified and metallurgical characterization completed.Process optimizations will be conducted ...
