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 ...

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 ...

Synchrotron-based science has had a great scientific impact and will continue to have great impact going forward. In spite of the large investment in the 3rd generation light sources, most beam lines do not preserve the sources phase profile or brightness all the way to the sample. For these high brightness light sources, errors are almost completely due to distortion in the front-end optics cau ...

Accelerators used for nuclear-physics research require megawatts of radio-frequency energy. They currently employ vacuum-tube power amplifiers or conventional solid-state amplifiers that are inefficient and therefore consume a great deal of prime power. Many other applications including semiconductor processing, cellular-telephone base station transmitters and military communication systems simila ...

Conventional indoor environmental monitoring technologies are expensive, cumbersome to install and maintain, and do not provide the distributed granularity required to capture the necessary details for efficient energy management of commercial buildings. Developments in wireless sensor networks (WSN) provide substantial framework for monitoring and addressing indoor environments at scale. However ...

ABSTRACT: Accudyne proposes a SBIR program to develop an automated material placement process for aircraft radomes and demonstrate it by forming quartz cynate ester fabric over an existing radome tool. The process employs computer simulations to model the forming process and compute a 2D fabric pattern as well as a four degrees of motion machine to form the fabric over the curved radome tool. T ...
