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 ...

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 DEMONSTRATION WILL BE PERFORMED THAT WILL SHOW THE UTILITY OF REAL TIME ANIMATION OF NUCLEAR WEAPONS EFFECTS DATA. DATA DEPICTING THE PROPAGATION OF AN AIRBLAST, GROUND SHOCK AND CRATER FORMATION WILL BE SIMULTANEOUSLY ANIMATED ON A 3-D GRAPHICS WORKSTATION. RECENT ADVANTAGES IN COMPUTING HAVE MADE IT POSSIBLE TO RENDER 3-D SHADED IMAGES OF POLYGON DATA AT INCREDIBLE SPEEDS. BY USING EXISTING SO ...
