Neutron multiplicity can provide effective detection and identification of shielded Special Nuclear Materials based on analysis of the time correlated neutron multiplicity distribution. RMD is developing two key materials for such applications: Cs2LiYCl6:Ce (CLYC) scintillator and dual-mode plastics.  CLYC offers efficient thermal neutron detection and excellent separation between gamma and neutr ...

During altitude-induced hypoxia, operator cognitive and physical capacity degrades, compromising individual and team performance. Cognitive degradation is linked to falling brain energy levels, increased reliance on anaerobic energy production and lactate accumulation. Ketones are the evolutionary alternative substrate to glucose for brain metabolic requirements; previous studies demonstrated that ...

OKSI will design and build a Precision Guidance Seeker (PGS) for the 81 mm munition. We will enhance and port our target acquisition and tracking algorithms to a real-time processor onboard the PGS, which will receive target-scene imagery prior to launch or while in flight and will deploy post apogee. OKSI will test the algorithms extensively with a wide range of military-relevant real-world data ...

At present, there are no solutions for equipping Class 1 and 2 unmanned aerial system (UAS) platforms with weapons systems that provide the capability for opportunistic engagement of high value targets (HVT). Munitions deployed on larger UAS, and other fixed-wing SOCOM assets, greatly exceed the payload capacity of Class 1 and 2 UAS assets currently in use for intelligence, surveillance, and recon ...

TDA Research, Inc. (TDA), designed, built, and tested a dense array of 100 very low cost infrasonic sensors. Due to their low cost (1/100x-1/10x the cost of other infrasound sensors), they can be economically deployed in very large numbers; such large arrays can gather more information than a few expensive sensors. They are sensitive from 0.1 Hz - 100 Hz down to 0.08 Pa. We tested the sensors in s ...

DTRA uses High Fidelity Computer Codes (HFCC) to investigate weapon effects and techniques for countering Weapons of Mass Destruction (WMD). End-to-end HFCC simulations in support of the DTRA Agent Defeat Warfighter Capability will require calculations including multiple phenomena that occur in vastly different time scales (µ-sec to hours). As DTRA becomes increasingly reliant on computational mo ...

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. ...

A generalized network topology-aware algorithm has been developed that efficiently maps structured and unstructured domains onto available nodes to minimize MPI message passing costs. The methodology utilizes sub-domain inter-dependency information, readily available from standard domain decomposition codes, along with a simulated annealing optimization technique to automatically assign sub-blocks ...

By the conclusion of Phase 1, important discoveries were made concerning the technological, market, and business feasibility of the Rapid Acquisition Platform. We have concluded that the RAP is feasible and may proceed to product development. In Phase II, GBTI will develop an end-to-end RAP utilizing the scientific and technological discoveries made in Phase 1. Phase 2 will be implemented over the ...
