Current data collection is growing faster than our ability to store and analyze it. Soon, data streams of 100Gb/s will be common. These data will need to be processed as they arrive. New statistical methods for incremental analysis are needed. We propose an approach called Robust Representation which will bound the analytical processing by setting upper bounds based on the available processing ...

Composite materials have emerged as the materials of choice for increasing the performance and reducing the weight and cost of military aircraft. Nevertheless, reliable prediction of composites behavior in both static and cyclic load situations are far from complete, due to limitations of current analysis methods and to uncertainty and statistical variation of composite behavior under a given set ...

Technsys Inc. proposes to develop an automatic parallelizing (APP) tool to identity the potential performance bottlenecks of legacy software code and then convert inefficient code segment into highly scalable and optimized software code by using state-of-the-art memory trace-based code optimization and parallelization techniques.

Central Processing Unit (CPU) chip makers made two advancements in recent years: (1) hyper-threading (e.g., Intel HT technology) to allow a single processor core to execute multiple instructions simultaneously, and (2) fabrication of dies with multiple processor cores. Exploiting those requires new code in C#, Java, or other languages that embrace threads. A thread is a conventional sequential pro ...

ABSTRACT: Our approach is to enable the proven fragmented antenna design from GTRI at Ka-band frequency range through the highly dimension controlled and low loss PolyStrata process at Nuvotronics. This will provide frequency scalability, connectivity to phased array electronics through the microcoax PolyStrata transmission lines and ultra-compactness and conformity to a predesigned shape. This i ...

ABSTRACT: We propose the assembly of a coordinate registration assessment suite applicable to over-the-horizon radar (OTHR). The suite includes a 3-D ionospheric model coupled with a 3-D magneto-ionic ray tracing code. The propagation model will have sufficient fidelity to accurately capture the effects of atmospheric gravity waves down to the high frequency limit. The propagation model will ...

ABSTRACT: Aircraft oleo-pneumatic landing gear shock struts require a precise gas to fluid ratio. Measuring oil fluid level explicitly requires time consuming service and temporary aircraft inoperability. Current approaches to verify the operational readiness of landing gear shock struts forgo measuring oil fluid level directly, and instead compare x-dimension (shock strut extension) to gas pre ...

ABSTRACT: In this SBIR effort we will develop a packaging process and demonstrate (Phase I) a prototype of high power Photodiode (PD) that has a normal incident, pigtailed fiber input and a coaxial RF output that operates from DC to>60GHz. We will apply and extend (Phase II) the aforementioned packaging process to single PD, balanced PD and array of PDs that work from DC through entire W-band. De ...

ABSTRACT: NanoSonic has developed ultra-lightweight (0.008 g/cm2), Thoraeus Rubber (TR) that demonstrate EMI shielding up to -100 dB from S-band (2 GHz) through Ka-band (40 GHz) and protection against nuclear ionizing radiation. Sub-GHz measurements are underway to demonstrate TR as a shielding replacement for copper. Current TR materials are based on thin films produced via self-assembly manuf ...

ABSTRACT: In order to accommodate the transition from standard to high-definition imagery in unmanned airborne platforms, it is necessary to find a way to reduce the increased transmission bandwidth of the system. One viable solution is to provide an onboard image processing computer that tracks objects of interest and transmits only that portion of the image in high-definition. However, UAV ...
