Terrorist use of radioactive nuclear materials via nuclear and/or radiological dispersion devices (dirty bombs) is a serious threat. Therefore, it is crucial to detect proliferation of nuclear material. Critical challenges include: (a) high sensitivity detection of signature emissions from radioactive isotopes, and (b) cost-effectiveness for deployment of sensor networks across large storage facil ...

Our Fused-Realities-Assessments-Modules(FRAM) enables innovative new levels and types of automated quantification strategies for combining human and system performance in real-time for fused performance monitoring and after-action-review purposes. FRAM accomplishes this by fusing output of normative models of behaviors (cognitive/procedural/team), human states (physiological/affective), system sta ...

Under this Phase II effort, the design of a modular 60 kw (3.6 MJ) shock tolerant composite flywheel for backup/ride through power will be finalized. This composite flywheel design will make use of a novel low cost thermal press cure process to fabricate the individual composite rings used to build up the flywheel. The manufacturing process parameters used in previous hydroburst testing of initial ...

If a computer system suffers a cyber attack, any compromised component that is simply reinstalled will remain vulnerable to the attack that damaged it; so replacements should provide equivalent services implemented differently. This defense can be applied proactively, to create a"moving target"by periodic reconfiguration. Implementing these strategies requires an effective way to create diversity. ...

Providing Army combat medics with meaningful experience in treatment of battlefield injuries is a particular challenge. Moulage has the potential to assist in acquiring what could otherwise be very hard-to-come-by preparatory experience for distressing real-life emergencies medics and soldiers may encounter in the field. However, current approaches to moulage are limited in their ability to reflec ...

Superconductor digital circuits, operating at very high clock speed, can directly process wideband digitized radio frequency (RF) signals. By integrating such digital processing circuitry together with superconductor analog-to-digital converters (ADCs), we propose to develop the next generation digital-RF receivers. Leveraging the recent development of multiple superconductor ADCs on the same chip ...

xß-Ga2O3 has emerged as a potentially disruptive semiconductor with a predicted breakdown field of ~8 MV/cm which is more than twice the breakdown field for the incumbent wide bandgap semiconductors GaN and SiC. The availability of ß-Ga2O3 bulk substrates sets this material apart from other wide bandgap materials for power electronic applications. However, the challenge is to find suitable epita ...

The proposed program will develop dielectrics for dc superconducting power transmission cables that are cooled with cryogenic helium gas. The Dielectrics will be sealed again helium gas penetration and allow for an operating voltage of 12 kV in a pressure of 2 MPa at 50 K. The dielectrics will be designed for use with all helium facing components of power transmission systems based on CORC cables. ...

Today the evaluation methods employed in the development and assessment of soldier borne Personal Protective Equipment (PPE) system designs are often extremely slow, expensive, and subjective, resulting in significant delays and expense in the fielding of improved designs. Recent rapid advancements in digital human modeling now allow the development of a multi-scale, comprehensive PPE evaluation t ...
