A motif is a non-commonplace, specific narrative element (such as a striking event, character, or object) that is repeated across stories found within the same cultural group, and concisely expresses complex cultural and political ideas through the inferences it evokes about a particular situation. If we can track motifs in communications, we will have a significant advantage in modeling informati ...

TYBALT (Transcending cYber Barriers with Automated Language Tracking) primary goal is the automatic detection of adverse intentions against US forces via publicly available information (PAI). Our “Intent to Act Adversely Detector” (ITAAD) is based on empirically-driven cognitive models linked to features detectable in the structure (rather than content) of written language: Integrative Complex ...

Collective allostatic load (CAL) is known to cause the degredation of team performance in a variety of contexts. SIFT is proposing MEDULLA (Monitoring Emergent Duress Under Long-Lasting Allostasis), a multi-method approach based on physiological, cognitive, and behavioral measures to develop and fine-tune algorithms for assessing CAL and predicting changes to CAL that can affect team performance. ...

This project will develop and deploy a comprehensive force protection vulnerability analysis process that accommodates diverse and large geographic areas, public events, infrastructure interdependencies, attacker goals, means, and methods, and defender priorities. This process will be based on the Vulnerability Assessment and Prioritization Methodology (VAPM) originally developed and applied to do ...

Tellurite glass compositions show significantly enhanced Raman scattering behavior. Optimizing these oxide glass compositions with heavy-metal-oxides(HMO) leads to easily fiberizable and highly non-linear fibers with transparency in the mid-IR wavelength region. These fibers are ideally suited for cascaded Raman lasers to generate multiple wavelengths in the mid-IR region. Furthermore, the high op ...

This Small Business Technology Transfer Phase II Program will demonstrate a magnetic field sensor device of high sensitivity using spin-dependent tunnel (SDT) materials. The tunnel materials will be developed with guidance from the state of the art realistic atomistic modeling and aided by state of the art nanostructural characterization techniques of 3-D atom probe and high-resolution transmissio ...

An anti-submarine warfare concept is proposed in which a low-cost and easily-deployable temporary submarine detection zone is created in littoral waters. The concept uses solid-state magnetic field sensors to detect the passage of submarines, and acoustic transmitters to relay the data to a small number of in-water receiver units. The data is then communicated from these units to a manned off-sit ...

This Phase I SBIR program will determine the feasibility of a unique sensor and test technology that measures trust levels in the operation of analog or digital integrated circuits (IC) through the use of device specific quiescent current (IDDQ) fingerprints. The IDDQ sensor is based on microelectronic magnetic field sensors, which are inexpensive, highly versatile, wide dynamic range, non-pertur ...

BOTH ATMOSPHERIC AND HIGH-ALTITUDE NUCLEAR EXPLOSIONS WILL PRODUCE MAGNETIC SIGNALS THAT ARE DETECTABLE OVER VERY LARGE DISTANCE. AN UNDERGROUND EXPLOSION WILL ALSO PRODUCE A MAGNETIC SIGNAL, BUT IT IS DETECTABLE AT MUCH SMALLER DISTANCE. THIS IS BECAUSE THE UNDERGROUND FIREBALL IS INERTIALLY TAMPED BY THE MORE DENSE EARTH, AND BECAUSE THE LOW FREQUENCY ELECTROMAGNETIC WAVE IS STRONGLY ATTENUATED ...
