Surface detection of specific radioisotopes of the noble gases xenon and argon are essential for detection and discrimination of underground nuclear explosions. We propose a unique combination of numerical modeling and stable isotope release experiments to enhance the predictability of subsurface transport of the noble gases of interest. Our proposed research will identify and quantify the physi ...

Reliable automated pattern recognition in the current system is limited by excessive noise and clutter combined with insufficient and/or ambiguous features. Our team consisting of AcornSI and Leidos thus propose a multi-step approach based on the combined effects of improved detection, feature extraction, phase identification, and global association. A key innovation here is creating a new classif ...

OBJECTIVE: Develop a Forensic DNA Analysis Kit for Genetic Intelligence that can be used on unknown human DNA samples collected from the battlefield to provide information about the individual who deposited the sample, such as potential ethnicity, height, eye color, hair color, age, sex, and/or facial features. The kit should leverage Short Tandem Repeats (STR), Single Nucleotide Polymorphisms (S ...

"The perturbation of the plasma density and current flow of an imploding gas puff load by the Rayleigh Taylor (R-T) instability is predicted to be the major impediment to using a long current pulse generator to produce x-rays for radiation simulationapplication. HY-Tech proposes a thin wall low Z cylinder to statically confine a gas puff load in the anode-cathode gap of a plasma radiation source ( ...

Large X-ray generators using gas fill loads are a key element in the DTRA simulator program. Consistent relative timing between the injection of the gas shell and the generator current pulse is crucial to producing consistent, high-yield x-ray pulses.To that end HY-Tech proposes replacing existing high voltage trigger pin technology, with a sensitive, all fiber-optic heterodyne interferometer ba ...

"Solus INC. proposes development of a Triad of Agent Defeat Polymers, termed Triad Polymer Agent Defeat or TPAD, which are designed to be directly incorporated into the standard HTI titanium boride / perboric acid / hexachloroethane HTI explosive matrixutilized by the Weapons Directorate at Eglin AFB. The triad polymer complex consists of three novel proprietary families of polymers functioning op ...

Accurate blast simulations based on first-principles, 3-D hydro-codes require hours on notebook PCs. Graphical processing units (GPUs) offer the potential of drastic reductions in run-times. Typical computational fluid dynamics codes perform of the order of 10-100 operations per memory fetch and store. In order to harness the potential of graphical processing units (GPUs), near-perfect streaming ( ...

"We developed a super-sensitive technique called Multi-Photon Detection (MPD). MPD has been used to improve the sensitivity of protein detection, including immunodiagnostics and proteomics. The development of MPD enabled methods for detecting a subattomole/ml amounts of proteins has been documented. The detection of the differentially displayed proteins, i.e. elucidation of promising set of the ...

IT IS PROPOSED TO DEVELOP A MANAGEMENT METHODOLOGY FOR PERFORMING TRADEOFF STUDIES OF NUCLEAR SURVIVABILITY OPTIONS FOR BATTLEFIELD SYSTEMS. THE PURPOSE FOR THE METHODOLOGY IS TO PROVIDE SYSTEMS MANAGERS (AND THEIR ADVISERS) A METHOD FOR ENSURING THE COST-EFFECTIVE SURVIVABILITY TECHNIQUES ARE INCLUDED IN THE SYSTEMS PLANNING IN EARLY STAGES. THE INTENT OF THE PROPOSAL IS TO SUPPORT IMPLEMENTATION ...

THE DAMAGING EFFECTS OF NUCLEAR AIRBLAST, THERMAL AND PROMPT RADITION, AND EMP ON EXPOSED EQUIPMENT AND STRUCTURES ARE WELL KNOWN. AN ADDITIONAL, LESS WIDELY RECOGNIZED BUT POTENTIALLY SERIOUS NUCLEAR EFFECT IS THAT OF AIRBLAST-INDUCED SHOCK (ABIS). EQUIPMENT MOUNTED INSIDE AN ENCLOSED SPACE CAN BE EXPOSED TO LARGE INDUCED VELOCITIES AND ACCELERATIONS, PRIMARLY IN THE HORIZONTAL DIRECTION. THE INT ...
