Reliable automated pattern recognition in the current system is limited by excessive noise and clutter combined with insufficient and/or ambiguous features. Our team consisting of AcornSI and Leidos thus propose a multi-step approach based on the combined effects of improved detection, feature extraction, phase identification, and global association. A key innovation here is creating a new classif ...

The Radionuclide Aerosol Sampler and Analyzer (RASA) is a completely automated monitoring system that detects airborne radioactive particles and is one of the detection systems used in the U.S. and global International Monitoring System (IMS) of the Comprehensive Nuclear Test Ban Treaty Organization (CTBTO) to detect nuclear detonations. Mainstream proposes develop a high-efficiency cyclone separa ...

In Phase II of PLATO, we will develop a prototype plan and goal identification system that employs a rich model of domain actions and events, extracted automatically from a massive amount of real-world domain-relevant information, to model agent-specific action costs and to process sequences of agent actions and events, extracted from text, as an agent plan in progress. The system will be able to ...

The goal of this project is to design and develop Semantic Analysis Technologies for the Identification of Dual Use Research of Concern (STIR). STIR processes scientific documents using semantic technologies and inference algorithms to identify potential for Dual Use Research of Concern (DURC). The focus is on 15 high consequence pathogens and toxins and 7 experimental categories identified as DUR ...

During the Phase I effort, Proportional Technologies, Inc. developed non-saturating components for a military battlefield dosimeter based on ionization chamber technology. Chambers were thimble-shaped, made out of carbon, and incorporated different materials for the conversion of fast neutrons, thermal neutrons, and gamma radiation. Extensive testing showed that the proposed solution is feasible. ...

MODELING OF THE AMBIENT AND PROMPT IONOSPHERIC REGIONS IN A THIN LAYER APPROXIMATION ALLOWS AN EFFICIENT METHOD OF DETERMINING THE TIME EVOLUTION, PROPAGATION, AND SIGNAL STRENGTH OF THE 0-10 SECOND MHD EMP ASSOCIATED WITH HIGH ALTITUDE NUCLEAR DETONATIONS.

SUBSTANTIAL PROGRESS HAS BEEN MADE IN RECENT YEARS TO DEVELOP AND VALIDATE MODELS WHICH CAN PREDICT THE PHYSICAL EFFECTS OF NUCLEAR WEAPONS ON STRATEGIC STRUCTURES. SIGNIFICANT UNCERTAINTIES REMAIN, HOWEVER, IN THE CONFIDENCE LEVELS ATTRIBUTABLE TO THESE PREDICTIVE CAPABILITIES. THIS APPROACH WOULD IDENTIFY AND PRIORITIZE THOSE ACTIVITIES, ALONG WITH THEIR ASSOCIATED BUDGETARY AND SCHEDULING CONSI ...

THE SPATIALLY RESOLVED PLASMA DISTRIBUTION BETWEEN THE ELECTRODES OF A PLASMA EROSION OPENING SWITCH (PEOS) DURING THE CLOSED AND OPENING PHASES OF THE SWITCH IS NEEDED TO UNDERSTAND SWITCH OPERATION. CONVENTIONAL HOLOGRAPHIC TECHNIQUES ARE NOT SUFFICIENTLY SENSITIVE TO STUDY THE 10 TO THE 13TH POWER/3CM PLASMA ENCOUNTERED HERE, AND ARRAYS OF LANGMUIR PROBES ARE REQUIRED TO OBTAIN SPATIALLY RESOLV ...

THE DISTRIBUTION OF THE MAGNETIC FIELD IN A HIGH CURRENT PLASMA DEVICE PROVIDES IMPORTANT INFORMATION ABOUT THE DEVICES OPERATION. TRADITIONAL FARADAY ROTATION, ZEEMAN EMISSION SPECTROSCOPY, AND MAGNETIC PROBE TECHNIQUES SUFFER FROM POOR SPATIAL RESOLUTION BECAUSE THE MAGNETIC FIELD EFFECT IS INTEGRATED ALONG THE LINE OF SIGHT FOR THE OPTICAL TECHNIQUE AND THE PROBES PERTURB THE PLASMAS. A LASER I ...

A PHYSICAL PROPERTY OF EARTH FORMATIONS THAT STRONGLY INFLUENCES THE RATE OF ATTENUATION OF A SHOCK WAVE IS THE BULK VOLUME OF AIR OR GAS ENTRAINED IN THE POROSITY. AS A RESULT, THE ACCURATE DETERMINATION OF THIS GAS VOLUME IS IMPORTANT FOR PREDICTING THE EFFECT OF A SHOCK WAVE ON SUBSURFACE STRUCTURES. THE OIL AND GAS INDUSTRY HAS USED GEOPHYSICAL WELL LOGS FOR YEARS TO IDENTIFY AND EVALUATE THE ...
