SBC: TECH-X CORPORATION Topic: AF11BT08
ABSTRACT: In this STTR Tech-X corporation in partnership with the University of Washington will improve a commercial plasma modeling tool, Nautilus, for simulating high-temperature multi-fluid plasmas for problems such as the field reversed configuration, dense plasma focus and the plasma opening switch. Semi-implicit algorithms will be implemented in Nautilus so that the speed of light and elec ...STTR Phase II 2014 Department of DefenseAir Force
Subspace Tracking and Manifold Learning Based Heterogeneous Data Fusion for Unexpected Event DiscoverySBC: INTELLIGENT FUSION TECHNOLOGY, INC. Topic: AF16AT12
We aim to develop data-driven heterogeneous data fusion approaches for unanticipated event/target detection, which will be more robust and immune to model mismatch problems encountered by model-based approaches. Considering the low intrinsic dimensionality of the sensor data, we propose several data-level fusion approaches based on some state-of-the-art dimensionality reduction techniques. For lin ...STTR Phase I 2016 Department of DefenseAir Force
SBC: Enig Associates, Inc. Topic: AF15AT22
ABSTRACT: Enig Associates, Inc., a small business providing advanced modeling and simulation capabilities to the DoD and DoE, is proposing an innovative and novel electrical approach, using explosive-driven flux compression generators (FCG) to convert explosive chemical energy to electromagnetic energy with very high current output and superb energy conversion efficiency and then Joule heat light ...STTR Phase I 2015 Department of DefenseAir Force
SBC: INFOBEYOND TECHNOLOGY LLC Topic: AF13AT08
ABSTRACT: Coordinating and sharing information across multi-level security (MLS) networks are of great interest in many military applications. However, it is very challenging to accomplish those goals due to the heterogeneous security classifications of different network domains. The recent proposed cross-domain solutions (CDS) provide initial steps to make such applications possible. However, th ...STTR Phase I 2014 Department of DefenseAir Force
SBC: ATMOSPHERIC & SPACE TECHNOLOGY RESEARCH ASSOCIATES LLC Topic: AF11BT29
ABSTRACT: The Air Force seeks to improve the accuracy of orbit specification and of 72-h orbit predictions beyond present capabilities. Thermospheric neutral density and satellite ballistic coefficient strongly impact satellite drag estimation, which is a leading source of error in orbit predictions in LEO. The goal of this Phase II project is to develop a satellite drag specification capability ...STTR Phase II 2014 Department of DefenseAir Force
SBC: SEAKR ENGINEERING, LLC Topic: AF11BT12
The SEAKR team proposes to continue development of the advanced protocol routing system begun in the Phase I effort, to reduce risk toward a flight deployable system for SATCOM assets such as Iridium NEXT. SEAKRs development of the Iridium NEXT modem...STTR Phase II 2016 Department of DefenseAir Force
SBC: MINERVA SYSTEMS & TECHNOLOGIES LLC Topic: AF15AT17
ABSTRACT: Speech recognition technology is in wide use today and has been successfully integrated in a number of applications. Most of these applications require a microphone located near the talker. However, when a distant microphone is used where the speaker is at some distance from the microphone as in a hands-free communication, or in a meeting room, there is a major problem with the captured ...STTR Phase I 2015 Department of DefenseAir Force
SBC: MINERVA SYSTEMS & TECHNOLOGIES LLC Topic: AF15AT17
Automatic speech recognition (ASR) technology is in wide use today and has been successfully integrated into a number of applications. Although there are also many potential applications for automatic speaker identification (SID), SID accuracy rates are generally not sufficient for widespread use in practical applications. For high accuracy ASR and SID, the microphone must be located near the talk ...STTR Phase II 2016 Department of DefenseAir Force
SBC: Intelligent Automation, Inc. Topic: AF13AT02
ABSTRACT: Intelligent Automation Inc. proposes to design a robust decision making and dynamic spectrum access (DSA) system for satellite communications under uncertainty. Our system integrates various types of uncertainty caused by environment, regulation, uncontrollable user effects, and prediction. We will first develop methods to quantify the uncertainty by either individual observation or col ...STTR Phase I 2014 Department of DefenseAir Force
SBC: Intelligent Automation, Inc. Topic: AF13AT14
ABSTRACT: We propose a comprehensive Risk Assessment of Disclosure via Automated Reasoning (RADAR) system. This system will leverage and advance various theoretical models in statistical inference (e.g., probe selection and posterior estimation) and information theory (e.g., entropy approach) to obtain a set of analytical tools for information disclosure analysis. These tools are integrated into ...STTR Phase I 2014 Department of DefenseAir Force
