Award Data

Mechanical damage (typically from third party excavations) is the most frequent source of leaks and ruptures in pipelines. The most common type of mechanical damage is dents, sometimes associated with secondary features such as gouges, external corrosion, or cracks. Currently used techniques for assessing dents are not accurate enough for reliable determination of fitness for service. In this p ...

EMC2''s Phase II proposal focuses on continuing development of "Soft Crack Arrestors" through additional key material property, detailed analytical refinement of the design, and full-scale pipe validation testing. This material testing will be done over a range of temperatures to cover extreme conditions for future pipeline designs, with special attention to arctic applications. It is also essen ...

Understanding the kinematics of intruding structures (floor plans, doors, roofs, etc.) as well as dummy motions is critical to safety related research. DTS believes the best way to acquire this data is to use small lightweight sensor packages to dynamically track the motion of single points using six degrees-of-freedom measurements. This methodology does not require line of sight to the measured ...

Emc2's proposal provided to DOT in response to SBIR Research topic 07-PH1 on "Design Optimization for Soft Crack Arrestors" focuses on the development of key material property data needed to design "soft crack arrestors". This testing will be done over a range of temperatures to cover extreme conditions for future pipeline designs. It is also essential to develop this data at the loading rates t ...

This SBIR project will explore innovative application of the PI's proprietary microwave imaging technology to time-resolved thermoreflectometry for non-destructive detection of rebar corrosion in concrete. This is based on the principle that a corrosion layer surronding the rebar serves as a thermal insulator and, as a result, corroded rebars cools more slowly than uncorroded ones upon heating. ...

The nightmare scenario in HAZMAT transport (or storage) is an incident in the proximity of a densely populated area. This issue is so critical that Congress has, on a number of occasions, considered restricting HAZMAT transportation, routing it around metropolitan areas. While so far such restrictions have not been implemented, the HAZMAT transportation industry faces mounting legal and insuranc ...

This proposal seeks to demonstrate the feasibility of using impulse radar techniques to detect and identify explosive detonators. It relies on the fact that a radar impulse will excite natural electromagnetic resonances which characterize the size, shape, and material composition of an object. These resonances are present in the scattered transient return from the object and can be extracted by ...

Accuwave Corporation will study the feasibility of a volume holographic, phase-encoded optical image correlator for credit card and document validation and security application. Fourier transform holograms of a phase-encoded input image are stored using wavelength multiplexed holographic gratings in a photorefractive crystal. High spatial resolution images can be sotred with low crosstalk using ...

We Propose to enhance rotorcraft simulation model to support land and sea-based flight testing and operational analysis. The model enhancement will resolve the long-time perplexing problems related to the fundamental simulation requirement for an accurate prediction of rotorcraft response in full range of flight. The solution proposed is to improve the widely used finite state dynamic wake ...

A new Navy process substitutes low toxicity trivalent chromium for toxic hexavalent chromium in aluminum conversion coatings. Further work is needed to investigate variations on the original formulations, with special consideration to formulas useful with common alloys of aluminum. Both a yellow and a blue-bright conversion film are desirable. Fractional Factorial Experimental Designs will be used ...
