Empirical-based mathematical framework and computer algorithms, for representing human perception and cognition processes and limitations, which influence the recognition of salient information about rapidly changing events.

Objectives and Intellectual Merit: The infrastructure of modern civilization is a set of complex systems1 that dynamically interact across multiple layers of abstraction. Researchers from many disciplines2 are designing analytical tools for predicting the global and local behaviors of these complicated, multi-layer networks. Easily usable, available (open source) and inter-operated tools are neede ...

The Defense Threat Reduction Agency (DTRA) has been supporting research of energetic materials and incendiaries as payloads for weapons to defeat targets containing chemical and biological agents. Several universities and Navy labs have been involved in this research, and have narrowed down on a few material formulations that are efficient biocides. These formulations contain a chemical ingredient ...

The proliferation of nuclear and radiological weapons of mass destruction is a serious threat in the world today. The goal of this proposal is to develop a new, very low cost radiation detection technology that will be useful for detection and for surveillance of individuals who have been near radioactive materials. The technology can also be used for dosimetry, and will provide the technology for ...

With missions surrounding counterproliferation, nonproliferation and WMD reduction, the stakes for DTRA are incredibly high. Effectively conducting this work involves cooperation and coordination across a wide range of military and government organizations throughout the United States and the world. The decentralization of threats has led to an explosion in the sources and types of data needed to ...

At the completion of the research and development effort a Li foil multi-wire proportional counter (MWPC) neutron detector with more than 625 cm^2 of active area will be included in a portable radiation detection system. The system is expected to have an intrinsic thermal neutron detection efficiency of 55% or greater and gamma-ray rejection ratio (GRR) of 1.0x10^-8 or better. A gamma-ray spectrom ...

A drop-in 3He-tube replacement technology for thermal neutron detection does not exist today. It is critical for homeland security and nuclear safeguards applications. In this program, Triton Systems proposes to develop a light-weight, large-area, high efficiency portable neutron detector for passive interrogation using an innovative gas detector structure. The resulting 3He-free thermal neutron d ...

As the carry and protective gear of the modern war fighter increases, the burden on the human body will necessarily increase. In our present TALOS MkIII project, we are developing lower body augmentation to preserve speed and agility while bearing this weight. Yet we cannot ignore the impact of this weight on the upper body: in this project we propose to develop an upper body exoskeleton with p ...

A critical step in the extraction of elements from ore, especially rare earth elements that are found in complex minerals, is separation. Froth flotation is a highly versatile method for physically separating particles based on differences in the ability of air bubbles to selectively adhere to specific mineral surfaces in a mineral/water slurry. The particles with attached air bubbles are then ca ...
