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 ...

To address the urgent need for 3D flash-lidar technology for landing on solar system bodies and for spacecraft rendezvous and docking with satellites, an effort is proposed to fabricate, characterize, and test a versatile, high-sensitivity InGaAs APD 3D flash lidar and to advance the technology-readiness level (TRL) of lidar technologies suitable for NASA mission requirements. Leveraging an existi ...

Project SummarySimulation training is unique in its ability for repetitive practice of a wide variety of scenarios and to reflect on performance without jeopardizing a patient s safetySurgical skills simulators have been successful in bridging gaps of the current training modelhoweverthese simulators fall short of offering a complete operative experienceOperative exposure with live patients still ...

Space superiority requires space protection and space situational awareness (SSA), which rely on rapid and accurate space object behavioral and operational intent discovery. The presence of adversaries in addition to real-time and hidden information constraints greatly complicates the decision-making process in controlling both ground-based and space-based Air Force surveillance assets. The focus ...

N5 Sensors partnering with George Mason University (GMU) have demonstrated ultra-small, low-power gas sensors, ideally suited for integrated space suit monitoring. A single-chip carbon dioxide (CO2), oxygen (O2), and ammonia (NH3) sensors capable of operating at high-humidity conditions, different range of oxygen in the environment and with low-power consumption was demonstrated as a proof-of-conc ...

Abstract Atrial fibrillation (AF) prevalence is estimated to 1% of the general population in the United States. A shocking 30% to 60% (according to studies) of patients with AF are unaware of their diagnosis (silent AF). Most AF patients will suffer from congestive heart failure or/and develop thromboembolic events leading to a dramatic reduction of patients’ quality of life, and a significant c ...

SUMMARY Despite significant advances in the surgical and medical management of congenital heart diseasecongenital cardiac anomalies remain a leading cause of death in the newborn periodMost severe forms of congenital heart disease require multiplestaged surgical interventionsA significant source of the heightened morbidity and mortality associated with these operations is the development of cardia ...
