GRASP integrates three innovative new technologies: application intrusion detection, proactive deception of attackers, and application intrusion response into technology to collect intelligence on the humans behind cyber attacks and adapt the mandatory operating system policy to prevent the intrusion in the future. Once detected, intruders are silently redirected to the secure GRASP Deception Shel ...

We bring together research from cognitive psychology, social psychology and neuroscience to create an innovative approach to enhance recognition of facial images through brief exposure presentation. We rely on two presentation methods to produce a measurable affective reaction to facial images which is detectable through galvanic skin response. These presentation methods allow users to acquire inf ...

As Air Operations Centers (AOCs) expand their capabilities by integrating space and cyberspace information into the air domain, the influx of relevant data must be presented to avoid information overload while enabling shorter planning cycles as well as an increasing variety of effects on an assortment of targets.  Novel visualization techniques will be critical to ensure rapid comprehension of t ...

The team’s long-term mission statement for this program is “to commercialize a handheld device that provides speaker-identified speech-to-text transcription of multiple English-language speakers in noisy environments.” In Phase I, the team will conduct research in the required technical areas and determine the commercial feasibility of achieving this objective. Specifically, the team will id ...

AS AN ALTERNATIVE TO MERCURY-CADMIUM TELLURIDE (MCT), WE PROPOSE TO INVESTIGATE THE OPTICAL PROPERTIES OF A RECENTLY INVENTED CLASS OF TYPE II STRAINED-LAYER SUPERLATTICES MADE OF (GA, AS)RELATED COMPOUNDS. THE NEW CONCEPT HAS ADVANTAGES COMPARED WITH PREVIOUS EFFORTS IN THAT SMALL BAND-GAPS MAY BE ACHIEVED WITH SUFFICIENTLYTHIN REPEATING LAYERS IN THE SUPERLATTICES SO THAT THEY HAVE GOOD OPTICAL ...

WE PROPOSE AN AUTOMATED MOLECULAR BEAM EPITAXY (MBE) PROCESS FOR REPRODUCTABLE GROWTH OF SEMICONDUCTOR DEVICE STRUCTURES. WE WILL APPLY RHEED AND THERMAL OSCILLATION TECHNIQUES TO CONTROL THE RATE ANDCOMPOSITION OF THE LAYERS AND TO ENSURE THAT THE GROWTH PROCEEDS UNDEROPTIMUM CONDITIONS. A MASS SPECTROMETER WILL BE USED TO CONTROL DOPANT INCORPORATION LEVELS. FLUXES FOR OPTIMUM GROWTH OF THE DIFF ...

AN EFFECTIVE METHOD FOR REDUCING FLUX TRANSIENTS IN MOLECULAR BEAM EPITAXY (MBE) EFFUSION CELL SOURCE IS PROPOSED. MBE IS A USEFUL TECHNIQUE FOR FABRICATING MANY IMPORTANT ELECTRONIC AND OPTOELECTRONIC DEVICES WHOSE PERFORMANCE DEPENDS CRITICALLY ON REPRODUCIBLE MATERIAL STRUCTURES. TIGHT CONTROL OF THE STRUCTURES IS OFTEN HINDERED BY FLUX TRANSIENTS DURING SOURCE SHUTTER OPERATION. WE PROPOSE A M ...

We propose two novel sources for improved carbon and tellurium dopants in MBE growth for III-V compounds semiconductors where heavy doping is required. The compact carbon source is electron beam heated and has a very fast thermal response. It is expected that increased monatomic carbon species in the flux would improve the dopant behavior. The tellurium source produces ionized species which would ...

Strained layer superlattices of GaInSb/InAs have been shown to have many desirable optical and transport properties, especially for VLWIR (>12um) detection. We propose to explore its fabrication and device applications by growing on polar orientations. It is expected the piezoelectric effect would be beneficially extend its IR response to longer wavelength. This will also make material parameters ...
