In the proposed effort, we will leverage this extensive experience and capabilities to realize a frequency agile mmW radiometer that can cover the range of DC-110 GHz and can be scaled to DC-200 GHz under Phase II. Ours is a photonic system that multiplies and up-coverts a low-frequency reference signal onto an optical carrier (laser) using EO modulation, then uses the modulation sidebands to inj ...

Every asset ages. Pipes, roads, computers, cars, etc. This fact is inevitable. And, as a result of the aging process, every asset suffers a degradation in its intended capability or performance over time. Yet every day, millions of people in the U.S. get up in the morning expecting that they will be able to travel to work, drink clean water, use the Internet, and so on. It usually takes a catastro ...

Training in the symptoms of Spatial Disorientation (SD) has shown to be valuable in aiding pilots to recognize its onset and provide a means for mitigating its effects, but such demonstrations have traditionally been associated with specialized equipment and devices. Since the vast majority of pilots for the commercial aviation jet fleet are trained (or recertified) on 6-degree-of-freedom (DOF) h ...

Single chirality of single-walled carbon nanotubes (SWCNTs) is critical for their superb mechanical, thermal, optical and electronic properties. All known methods for producing nanotubes give mixtures of tubes with different chiralities. Physical separation of SWCNT by chirality is thus an enabling step for many potential applications and fundamental studies. The existing anion exchange resins are ...

Nanometrology International, Inc. (NMI) proposes to demonstrate the feasibility of 3-dimensional (3D) characterization of nanoscale objects using scanning probe microscopy (SPM) with a measurement uncertainty of less than 0.7 nm. To accomplish this task, we propose a novel method of 3D tip characterization and use of an innovative surface reconstruction algorithm recently introduced by NIST and th ...

TRI proposes to develop reliable methodology and protocols for in-service inspection,recertifying and retiring DOT COPVs to maximize service life while ensuring personnel safety. This method must be sufficiently robust to prevent in-service failures, while being straightforward and affordable enough to be conducted at cylinder recertification facilities. To accomplish this with a high degree of co ...

A nondestructive tool will be developed to quatitatively assess residual stress in pipelines from the exterior and through coatings. Residual stress is a critical factor that determines the cracking susceptibility of pipeline steels, but existing methods for measuring mechanical damage in pipeline steels are incapable of quantifying the residual stress levels. A larger gouge or dent does not nec ...
