Infrasound and seismic measurements are used by DTRA and the DoD for nuclear test monitoring, terrorist blast forensics, battle damage assessment, and environmental monitoring. However, these long wavelength physical signals are typically recorded through single-point sensors or sparse low density arrays. As a result, the critical signals of interest are often corrupted or masked by noise or inter ...

A significant performance gap exists between the theoretical number of Floating Point Operations (FLOPS) that a HPC machine is capable of sustaining and the number of FLOPS realized by real-world HPC applications. One of the principle reasons for this gap is the parasitic work that computational processes must do to communicate with one another. It has been shown that this communication work can b ...

PNTS proposes to develop a truly novel implementation of eye-safe terahertz (THz) spectroscopy that is unprecedented in the standoff detection regime for accuracy, low cost, and portability. PNTS has teamed with SC&A, Inc., and researchers from the University of Memphis to create a world class team of research and development personnel. We are proposing a continuous wave terahertz (THz-CW) spect ...

Orora Design Technologies proposes to develop electronic design automation (EDA) tools employing minimally invasive circuit design-based methods to mitigate single event effects (SEEs) for next generation Ultra-DSM CMOS (

The objective of this proposal is to develop enabling technology for the production of bulk scintillating nanocomposites that have gamma radiation detection properties of single crystal NaI but with the manufacturability of plastic scintillators. These performance criteria may be met by developing nanoparticle polymer composites with ultra-high nanoparticle loadings. These ‘ultra-composites’ w ...

Analysis of nuclear material samples in the field has many advantages over laboratory analysis. Laboratory analyses can be slow, involve increased expense, lead to additional waste generation and disposal problems, and may introduce errors due to sample degradation or mishandling. In situ analysis mitigates all of these problems. The specific aim of this project is the development of a truly por ...

A CONCEPT FEASIBILITY STUDY FOR A SATELLITE-BASED OPTICAL-INFRARED DISTURBED ATMOSPHERE SIGNATURE PROGRAM IS PROPOSED. THE INITIAL CONCEPT IS FOR A POLAR-ORBITING OPTICAL-INFRARED ANALOG TO THE HILAT SATELLITE WHERE-IN A HIGH PROBABILITY OF AURORAL ACQUISITION IS ANTICIPATED. INITIAL TECHNICAL DIFFICULTIES OF CRYOGENIC OPERATION AND EXPECTED LIFETIME ARE DISCUSSED IN TERMS OF THE IRAS SUCCESS. THE ...
