Military personnel often operate within urban, cavernous, foliage covered or indoor environments. In these areas, position navigation and time information becomes difficult and in some cases impossible to deduce from GPS signals alone. Under the proposed effort TRX will develop and implement an Android-based application that delivers GPS-denied navigation and mapping for tactical battlefield use. ...

We propose to develop a systematic approach of synthetically generating diverse types of large-scale, dynamic and high fidelity social network data via measurement calibration. Social network research needs access to realistic social media datasets for testing social network theory and developing network algorithms. However, the available social network data are either small, static, or cannot be ...

In this Phase II SBIR effort we will dramatically reduce the size, weight, and power requirements of a passive millimeter wave imaging system based on optical upconversion. To this end, we will integrate custom silicon-germanium low noise amplifiers that have been designed to efficiently couple with our high performance lithium niobate upconversion modules. In Phase I we analyzed the design requ ...

An architecture for linking geographically disparate N-DOF test beds to facilitate real-time distributed operations is proposed. An industry supported middleware solution, OpenDDS, is proposed as a basis for the required simulation software. A survey of existing laboratory conditions is performed. Adaptation to existing laboratory conditions is provided through the abstraction of simulation requ ...

Purpose: American Sign Language (ASL) is a visual and gestural language that is distinct from English, has its own grammar, syntax, vocabulary, and no text representation. Despite the differences between the languages, students who use ASL are typically assessed with protocols for English-speaking students, as few exist specifically for students who use ASL. Not surprisingly, prior research shows ...

THE ACOUSTIC CHARGE TRANSPORT (ACT) DEVICE IS A RELATIVELY NEW COMPONENT, FABRICATED IN MONOLITHIC FORM ON GAAS, THAT OFFERS TREMENDOUS POTENTIAL FOR CURRENT/FUTURE SIGNAL PROCESSING SYSTEMS. BECAUSE OF ITS NEWNESS, LITTLE SYSTEMS APPLICATION WORK HAS BEEN PERFORMED TO-DATE. THE AREAS OF GREATEST POTENTIAL ARE IN RADAR, SONAR, AND PARTICULARLY, ELECTRONIC WARFARE (EW). IN ORDER TO EXPLOIT THIS DEV ...

REMOTELY PILOTED VEHICLES OFFER A WIDE VARIETY OF CAPABILITIES RANGING FROM TACTICAL AND STRATEGIC MISSIONS TO NATIONAL RECONNAISSANCE. ALL THESE MISSIONS SHARE A COMMON NEED, THAT OF HAVING A SENSOR SYSTEM THAT CAN DETECT TARGETS THAT ARE DIM DUE EITHER TO THE "FOG OF WAR" OR TO DELIBERATE ATTEMPTS OF CONCEALMENT. THERE IS ALSO A GROWING NEED TO ACHIEVE LOW OBSERVABILITY FROM A SURVIVABILITY AS W ...

THE USE OF MULTI-SPECTRAL SPACE IMAGERY HAS BECOME A VERY POWERFUL MEAN TO PROVIDE GEOLOGICAL PARAMETERS PERTAINING TO ROCK MINEROLOGY, FAULT LIEAMENTS, AND STRUCTURAL CONTACTS ETC, FOR A GIVEN REGION. THESE INFORMATION ARE VERY USEFUL IN COMPLEMENTING DATA OBTAINED THROUGH CONVENTIONAL FIELD MAPPING. ENHANCEMENT OF THE MULTI-SPECTRALSPACE IMAGERY WILL ALSO ALLOW DIRECT VISUAL INTERPRETATION OF CH ...
