Sepax Technologies, Inc. has identified a new type of anoin-exchange resin which separates single-wall carbon nanotubes (SWCNTs) with >80% recovery yield and resolves in a single pass the chiral tubes of (6,5) well from commercial SWCNT starting materials by Chromatography. Improvement and scale up of the targeted resin production will facilitate the separation of chiral nanotubes for the academic ...

Under this effort, Sentient will develop mixed-EHL models to predict the performance of fluid film bearings for submarine applications. The models will consider critical design and operational parameters such as component geometry and surface finish, start up and shut down speeds/loads, and lubrication properties to predict torque, film thickness, and associated wear/efficiency. The result will be ...

Next-generation high-performance computers (HPCs) are built as massively parallel systems where the parallelism exists at many levels. These systems are a collection of nodes all working together. Each node generally contains more than one processor and each processor contains multiple cores. Managing and efficiently utilizing the different parallelism in such a system is a complex task. Furth ...

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 ...

ABSTRACT: Optical control of RF-signal transmission presents an attractive avenue for processing and transmitting RF information using various optical components, as opposed to electronic control, where metallic wires/cables are required. On a macroscopic scale, optical fibers offer low transmission losses, and hence are suitable for the distribution of control signals over long distances for lar ...

Advanced reconfigurable/reprogrammable communication systems will require use of commercial sub 100 nm electronics. Legacy radiation tolerant circuits fail to provide Single Event Upset (SEU) immunity at speeds greater than 500 MHz. New base level logic circuits have been demonstrated in Phase I that provide SEU immunity for sub 100 nm high speed circuits. A completely new circuit and system ap ...

This proposal presents a technique for the precise determination of distance between nodes of a planar array of nanosatellites for synthetic aperture and sensor array applications. The proposed effort will result in a navigational technique that can precisely determine the positions of nanosatellite sensor nodes in the array. The proposed innovation enables higher performance and low cost sensor a ...

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 ...

The proposed 45 nm radiation hardened platform based structured ASIC architecture offers the performance and density expected of a custom ASIC with the low manufacturing cost associated with a structured ASIC. The low cost, high performance customization of the structured ASIC portion of the chip is made possible by the 1-D 45 nm Mask-Lite process technology. The chip architecture is optimized for ...

Despite its promise, OpenCL adoption is slow, owing to a lack of libraries and tools. Vendors have shown few signs of plans to provide OpenCL libraries, and were they to do so they would likely be incompatible with one another, much as NVIDIA's BLAS (CUDA) is presently not interchangeable with Intel's BLAS (MKL). The unified language and environment of OpenCL allows the community to ensu ...
