DEFINITION OF THE STRUCTURE-MEDIA INTERACTION (SMI) LOADS ON A BURIED STRUCTURE IS ONE OF THE LARGEST SOURCES OF UNCERTAINTY IN ANALYZING THE SURVIVABILITY OF STRATEGIC STRUCTURES. ADVANCEMENT OF THE STATEOF-THE-ART IN THE MODELING OF SMI BEHAVIOR IS HAMPERED BY A LIMITED DATA BASE WHICH IS CONFINED TO OVERPRESSURES MUCH SMALLER THAN THOSE CURRENTLY OF INTEREST. THIS EFFORT PROPOSES TO DEVELOP AND ...

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.

Parallax Research, Inc. proposes to build an Ultra-High Vacuum compatible Wavelength Dispersive X-ray Spectrometer (WDS) that can be used on small spot Auger, XPS, TEM and FESEM analytical instruments for elemental analysis. The effort draws upon Parallax's experience in designing WDS systems for Scanning Electron Microscopes (SEM) and for XRF. This new type of x-ray spectrometer will eliminate th ...

Radiation tolerant Field Programmable Gate Arrays (FPGA’s) have gained wide and rapid acceptance by military and aerospace equipment suppliers; however, there are presently a limited number of chip-sets available for production and they are limited to one time programming; hence if program changes are subsequently required a backup or chip replacement is required. The lack of FPGA alternatives ...

A low-cost superconducting transition edge sensor (TES) microcalorimeter spectrometer is described for high energy and high spatial resolution X-ray energy dispersive spectroscopy and microanalysis. The proposed microcalorimeter instrument offers an energy resolution that is comparable to and potentially even better than wavelength dispersive spectrometers, thereby enabling the resolution of inter ...

During Phase I, Management Sciences, Inc. (MSI) proved feasibility of adapting their current technology into a product capable of improving performance resulting in increased efficiency and extended life cycles of heat pumps. The resultant product is a tool named the Heat Pump Sentient (HP-Sentient). The HP-Sentient will improve performance and reduce maintenance costs through aggressive goal-seek ...

Although protocols for securing email have been available for over twenty years, these protocols, by nature of their use of asymmetric cryptography, require users to have the public key or certificate of the correspondents. Grier Forensics will develop technology to use the Domain Name System (DNS) to distribute certificates and keys, making email secure, authenticated, and confidential, curbing t ...

This project will develop a new scientific instrument optimized for the advanced characterization of near-infrared fluorescent nanoparticles that can exist as left- or right-handed structures (enantiomers). Single-walled carbon nanotubes (SWCNTs) are the leading current example of such nanomaterials. Applied NanoFluorescence, LLC (ANF) proposes a novel multi-mode chiroptical spectrometer that can ...

During the Phase I effort, Semandex Networks and its team developed a prototype capability to detect trends in research publications by automatically identifying emerging concepts within the data. The implemented capability provides insights into past and
