Under the DARPA sponsored Naval Advanced Amorphous Coating (NAAC) program, a novel, thermal sprayed amorphous metal coating has been developed. Such a coating has demonstrated superior mechanical and corrosion resistance properties. Although the coating is designed to be life-of-ship, the application and operational conditions may compromise the integrity of the coating. For example, the applicati ...

IN THE TREATMENT OF THE DYNAMIC PROBLEMS OF STRUCTURES, TWO ALTERNATE TESTING METHODS, BASED ON EXTERNAL AND EMBEDDED SENSORS, EXIST IN THE LITERATURE. IF THE SENSORS RESPOND TO THE CHANGES IN THE DYNAMIC CHARACTERISTICS OF THE STRUCTURE, AND/OR THE ENVIRONMENT, THEN THEY ARE REFERRED TO "SMART" STRUCTURES. SMART SENSORS AND SMART MATERIALS HAVE BEEN USED FOR DETECTING STRUCTURAL DAMAGES AND/OR CO ...

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 ...

As the threat landscape continues to evolve, modern forces and especially foot mounted soldiers are increasingly tasked with conducting operations in either complex urban or remote cavernous environments where GPS signals are severely corrupted and/or unusable. The ability to track and navigate in unfamiliar subsurface environments such as canyons, subterranean caves, mines or other manmade subsu ...

A novel method for preparing carbon electrode structures having applications in electrochemical double layer capacitors (EDLCs) is described. The method for preparing these structures employs carbon (graphite) nano fiber materials and results in an electrode having both high surface area and high electronic conductivity; two essential characteristics for EDLC electrodes. The fabrication process ...

This program proposes to demonstrate an ultra-low power design methodology and circuits for digital logic employing advanced dynamic voltage scaling (DVS) for asynchronous NULL Convention Logic (NCL) circuits operating in sub-threshold to super-threshold voltage regimes. The power supply voltages of logic block partitions will be independently set by on-chip voltage controllers based on the data p ...

This project is based on a novel computer graphics technology for man/machine interfaces that relies on machine learning techniques, neural-like networks, and object recognition IU techniques. The key idea is to use a few "example" views of an object or person, to teach the computer to generate other views, under user control. WIth our technology we will develop an interactive (multimedia) interfa ...

Investment castings have well served both the military and commercial markets in such areas as waveguides and splitters for microwave applications, and for connectors, housings, heat sinks and mechanical parts for electronics, optical, instrumentation, and medical devices. Tomorrow's higher RF millimeter wave and communications electronics products, and more compact optical, instrumentation and m ...

The purpose of Phase I of this project is to determine the feasibility of developing an acoustic instrument for measuring temperature profiles using a combination of neural networks and broadband sonar. "Broadband sonar provides the necessary comparative information between frequencies to provide a great deal of the requisite information for determining temperature from sound speed. Because the ...

CERAMICS HAVE BEEN SHOWN TO BE VERY EFFECTIVE IN THE DEFEAT OF A WIDE RANGE OF KINETIC ENERGY (KE) THREATS. HOWEVER, THE USE OF CERAMICS IN ARMORED VEHICLES HAS BEEN LIMITED DUE IN MOST PART TO THEIR HIGH COST. CERAMIC PARTICULATE REINFORCED METAL MATRIX COMPOSITES (MMCS) PRODUCED BY PRESSURELESS LIQUID METAL INFILTRATION ARE INEXPENSIVE RELATIVE TO MONOLITHIC CERAMICS DUE TO THE LOWER COST OF THE ...
