Commodity graphics processing units (GPUs) offer tremendous computational throughput for relatively little cost. They have been shown to outperform microprocessors in the important metrics of FLOPS/dollar, FLOPS/Watt, and FLOPS/unit space and have already been applied to a wide range of numerically intense problems. In Phase I of this project, we demonstrated their potential to enhance complex C ...

We propose to develop and deliver a nano-patterned metallic light trap platform that will allow ultra-thin InGaN photovoltaics to exhibit extended lifetime by a factor of four when used in low orbit satellite operations. We will test the enhancement of light absorption in InGaN layers with In fraction of 25% for use as an effective method of realizing radiation ultra-hard solar cells for space-ba ...

Advanced turboshaft engine impeller disks work at a high rotational speed at elevated temperatures which vary from the disk rim to its bore. Due to contact with combustion gases, the rim possesses a significantly greater temperature than the bore. This temperature gradient implies different requirements for the mechanical properties of the material in the rim and bore areas. A nickel based superal ...

Current life prediction methods, such as AGMA, are empirical-based, deterministic in nature and cannot consider the effects of gear manufacturing processes, material microstructure and lubrication on fatigue strength. The estimated life is as good as the information entered by the user and it requires considerable design, manufacturing and field experience. In addition, current methods cannot take ...

The state-of-the-art FPA manufacturing technologies commonly generate some critical defects in the pixel elements, which adversely impact their operability and reliability. In Phase I, the feasibility of identifying, analyzing, and on exemplary basis, eliminating these defects indirectly through nanostructural analysis was demonstrated. In Phase II, this defect analysis and correlation approach ...

We propose to develop a comprehensive mixed-signal design solution with an IP infrastructure, design methodology and design automation tools to enable the use of regular fabrics and mask re-use. The IP infrastructure will consist of metal-reconfigurable analog/RF templates built on top of the existing PDF Solutions’ pdBrixTM solution. The design methodology will allow designers to achieve perfor ...

We propose to implement a novel countermeasure against the exploitation of integrated circuit hardware. The proposed countermeasure is applicable to both FPGAs and ASICs, increases design obfuscation and promises to block embedded hardware exploits. It also is fully compatible with virtually any other hardware exploit countermeasure and reduces forensic costs when exploits are suspected. The propo ...

A versatile and portable instrument for stray light detection and diagnosis at both visible and infrared wavelengths will be designed, built, and demonstrated. The core idea of the proposed approach is to use subaperture, rather than full aperture, illumination for stray light detection. The subaperture approach uses a scanning pencil beam (SPB) that provides information about the location of a s ...

Under this SBIR program, Ridgetop Group will introduce the first single-chip, low-cost, low-power, and lightweight data monitoring solution for applications on rotating machinery. To develop this innovative miniature data collection platform, Ridgetop proposes to:  Provide a novel data collector using submicron integrated MEMS/CMOS fabrication processes  Define a commercialization strategy ...

The global war on terror has dramatically changed the environment in which today's warfighter operates. Many of the locations in theater require moving troops and equipment into areas with unimproved landing zones. Loss of situational awareness in degraded visual environments is one of the largest threats to rotary wing aircraft operating in these areas. Phase Sensitive Innovations has built a pas ...
