In order to better protect critical infrastructure from cyber attacks, perimeter and passive defenses must be complemented with an active defense mechanism which elevates the risks, or costs, a potential attacker will face. The effectiveness of an active defense mechanism, however, is ultimately limited by its ability to detect threats fast, accurately, and reliably. For this Phase II project, we ...

RESEARCHERS ARE DEVELOPING AND DEMONSTRATING ADAPTABLE VIBRATION ANALYSIS SENSORS WHICH USE SPECIALIZED WEIGHTED-SENSITIVITY OPTICAL FIBER WAVEGUIDE STRUCTURES. SEVERAL METHODS TO CREATE THE NECESSARY SENSITIVITY VARIATIONS ALONG THE LENGTH OF THE WAVEGUIDE ARE SUGGESTED. EXTENSIONS OF THIS WORK TO FURTHER PERMIT THE REAL-TIME MODIFICATION OF SUCH SPATIAL FIBER SENSITIVITY PROFILES, AND HENCE THE ...

DATA ANALYSIS AND STATISTICS ARE OF INCREASING IMPORTANCE IN TRAINING SCIENTISTS, SOCIAL SCIENTISTS, AND BUSINESS PEOPLE. THE DEMAND FOR STATISTICS EDUCATION HAS GROWN RAPIDLY BUT STATISTICS IS NOTORIOUSLY DIFFICULT TO TEACH WELL. STUDENTS WITH MATHEMATICS ANXIETY OR WITH POOR MATHEMATICS PREPARATION FIND THE RELENTLESSLY SEQUENTIAL PRESENTATION OF THESE CORUSES PARTICULARLY DIFFICULT. RECENT ADVA ...

The trend toward replacement of highly toxic chemicals with less hazardous alternatives has created the demand for replacement of chromate conversion coatings for corrosion protection of aluminum alloys. Aluminum alloys are the predominate structural material used in aircraft because of their high strength-to-weight ratios, affordability and processability. Aluminum is subject to catastrophic fail ...

A NEW LASER CRYSTAL, PRAESEODYMIUM YTTRIUM LITHIUM FLUORIDE, IS BEING DEVELOPED FOR APPLICATIONS IN HOLOGRAPHIC INTERFEROMETRY. MOST PULSED LASER HOLOGRAPHIC INTERFEROMETRY IS PRESENTLY PERFORMED WITH EITHER FREQUENCY DOUBLED NEODYMIUM YAG OR WITH RUBY LASERS. THERE ARE A NUMBER OF LIMITATIONS IMPOSED BY EITHER OF THESE TWO CRYSTALS, SOME OF WHICH CAN BE OVERCOME BY THE NEW CRYSTAL. RESEARCHERS ...

Our objective is to develop an innovative cognitive knowledge-aided information processing framework to take very high rate intelligence data streams over wide areas and autonomously highlight Areas-of-Interest (AOIs) and targets for the image analyst without a priori knowledge of the area or location of the individual high interest targets. By using 100s of JADE based intelligent agents in Phase ...

RESEARCHERS ARE DEVELOPING MM WAVE SIS HETERODYNE RECEIVERS INTEGRATED WITH ON CHIP LOCAL OSCILLATORS FOR USE IN RADIO ASTRONOMY. THE RECEIVERS INCORPORATE SUPERCONDUCTING TUNNEL JUNCTIONS (SIS JUNCTIONS) AS THE MIXING ELEMENTS, TOGETHER WITH JOSEPHSON JUNCTION LOCAL OSCILLATORS, TO PROVIDE MIXING IN THE 50-700 GHZ FREQUENCY BAND. LOCAL OSCILLATORS BASED ON THE AC JOSEPHSON EFFECT HAVE DEMONSTRA ...

A LARGE UNCERTAINTY EXISTS CONCERNING THE QUANTITATIVE ABILITY OF THE OCEANS TO TAKE UP ANTHROPOGENIC CO2. A MORE COMPLETE UNDERSTANDING OF THE RELATIONSHIP BETWEEN OCEAN ANDATMOSPHERIC CHEMISTRIES WOULD BROADEN THE ABILITY OF SCIENCETO PREDICT THE MAGNITUDE AND RATE OF GLOBAL WARMING SO THAT APPROPRIATE COUNTERMEASURES COULD BE DEVELOPED AND IMPLEMENTED. AN ANALYTICAL INSTRUMENT IS NEEDED TO MAKE ...

Deployment of unmanned systems continues to expand across a wide range of missions; for example, logistics and resupply missions, force application and protection, and improving battlespace awareness. Presently these unmanned systems run at the lowest of four possible levels of autonomy, that is, in a teleoperated mode, and each system typically requires multiple operators. To address this proble ...
