In this proposal, AlphaSense, Inc. (AI) and the Oklahoma State University (OKState) detail the development of a novel Cavity Enhanced Terahertz Absorption Spectrometer (CETAS). Key innovations of the proposed system include: a) the use of a small Whispering- Gallery- Mode (WGM) cavity to achieve very long pathlength; and b) the integration of the WGM cavity with the conventional pulsed and continu ...

ABSTRACT: High-performance computing (HPC) programmers and domain experts, such as those in the Air Force's research divisions, develop solvers for a wide variety of application areas such as modeling next generation aircraft and weapons designs and advanced image processing analysis. When developing software for HPC systems, the programmer should not spend the majority of their time optimiz ...

The recent performance increases in graphics processing units (GPUs) have made graphics cards an attractive platform for implementing computationally intense applications. With their numerous parallel computational pipelines and SIMD architecture, modern GPUs can outperform high-end microprocessors by one to three orders of magnitude, depending on the problem. Most work to date at EM Photonics a ...

In this SBIR program, AlphaSense, Inc. teamed with the Center for Non-destructive Evaluations at Iowa State University to develop a compact, low cost handheld sensor for non-destructive material case depth verification. In phase I, we have proven the feasibility of using an alternating current potential drop (ACPD) sensor for non-destructive measurements of case depth. Phase II will be focusing on ...

In this proposal, AlphaSense, Inc. (AI) and the University of Michigan (UM) detail the development of a compact, portable, and low cost in-process weld defects detection system. Key innovations of the proposed system include: a) weld defects monitoring based on plasma emission characteristics; b) use the electron temperature of the plasma as an indicator of the weld quality, c) use multiple plasma ...

A simple clamping U bracket to secure itself under pressure on both sides of the aircraft's structural frame ribs. A clamp will be placed on every section where the bonded studs currently exist. A cavity on the bottom of each clamp will hold a stud or other tool to secure the blankets. The outer surface of the bracket will be made of rubber and the inner core will be made of 9255 spring steel, ...

Topic Synopsis: Current aircraft disposition tools are not designed to take advantage of predictive prognostic information that will be available on new systems such as the F-35 PHM system or the proposed Maintenance and Monitoring system for the E-2D Hawkeye. The central challenges in this topic are to (1) develop automated reasoner technologies to distill large volumes of PHM data into actionabl ...

Flight-testing is a crucial component in NASA's mission to research and develop of new aeronautical concepts, allowing for verification of simulated and wind-tunnel results, and exposing previously unforeseen design problems. Video is an invaluable tool for flight-testing, allowing the collection of a wealth of information; however, collected long-range imagery typically suffers from scintill ...

Gearbox seal wear and leakage is a major source of maintenance and downtime for rotorcraft. Sentient will use our advanced tribology modeling technology to evaluate coatings and surface texturing processes for carbon face seals and provide a generalized modeling approach that can replace physical testing of seals. These models will be used to evaluate several rotorcraft seal designs proposed by ou ...

Although biodiesels have been increasingly used in automobiles, trains, commercial aircrafts and heating systems, they are not currently used in the military aircrafts and land vehicles because they typically do not meet the JP-8 performance criteria as specified by MIL-PRF-83133E. Unintentional contaminations by the biodiesels into the jet fuels can introduce adverse effects, including engine ope ...
