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 ...

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 ...

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 ...

The ability to manufacture on the International Space Station will enable on-demand repair and production capability, as well as essential research for manufacturing on long-term missions.Having an Additive Manufacturing Facility (AMF) on the ISS will allow for immediate repair of essential components, upgrades of existing hardware, installation of new hardware that is manufactured, and the manufa ...

M Cubed has developed and patented technology to make carbon fiber reinforced SiC composites and components. In addition, the feasibility of doubling the toughness of SiC with carbon nanotube (CNT) reinforcement has been proven. In this program, M Cubed will demonstrate further innovative modifications of the above technology to make extremely lightweight, high toughness, low CTE optical component ...

Detectors and radiation monitors for future high energy and nuclear physics experiments must be able to withstand radiation environments several orders of magnitude harsher than those of any current device. At present, most radiation detectors are based on silicon technology, however, the practical radiation hardness limit of silicon falls far short of requirements in future high ener ...

Ethylene and propylene are the primary feedstocks for the manufacture of polyethylene and polypropylene, respectively. These olefins represent a major component of the polymer manufacturing cost. Consequently, there is significant economic benefit in minimizing losses of unreacted olefin from the process. Some olefin loss is a result of the need to remove paraffin from the polymerization reactor ...
