All rights reserved.5http://www.ntis.gov/images/logoRSS.jpghttp://www.ntis.govA preliminary validation study of three DSMC chemistry models, two recent and one standard, is presented. First the 2D geometry and numerical approach used to simulate the shock experiments is verified. Next, 2 different vibrational relaxation models ...http://www.ntis.gov/search/product.aspx?ABBR=ADA571739The long-term goal of the research is to increase the physical understanding of acoustic propagation in continental shelf and slope environments in the 50-4000 Hz band. This includes both the physics of the seabed and the coupling to physical mechani ...http://www.ntis.gov/search/product.aspx?ABBR=ADA571665Military structures are susceptible to high velocity impact due to both ballistic and blast loads. During a high velocity impact a shock wave much greater than static collapse resistance propagates through the material. Metallic structures usually un ...http://www.ntis.gov/search/product.aspx?ABBR=ADA571924LONG TERM GOALS: The long term goal of this project is to develop efficient inversion algorithms for successful geoacoustic parameter estimation and source localization, exploiting (fully or partially) the physics of the propagation medium. Algorithm ...http://www.ntis.gov/search/product.aspx?ABBR=ADA571694This project addresses the need for signal processing procedures as outlined in the Statement of Needs MM SEED-08-01, and seeks to develop a new technology for enhancing magnetic data by increasing data resolution and by estimating data noise for use ...http://www.ntis.gov/search/product.aspx?ABBR=ADA571506The long term goal of this research is to build an ecological modeling framework that facilitates understanding of the at-sea condition and health of various species of marine mammals. We will use the results from these models to explore and quantify ...http://www.ntis.gov/search/product.aspx?ABBR=ADA571598Goal: Apply time-dependent reliability/durability concepts to address prognostic CBM using: Available data (limited, censored), Expert opinion, Computer simulations (physics-of-failure data). ...http://www.ntis.gov/search/product.aspx?ABBR=ADA571995During the one year of this grant, we proved several breakthrough results to develop frameworks for approximation and fixed-parameter algorithms in planar and nearly planar graphs. In this final report, we detal these results and summarize the suppor ...http://www.ntis.gov/search/product.aspx?ABBR=ADA572036Petascale platforms with O(10(sup 5)) and O(10(sup 6)) processing cores are driving advancements in a wide range of scientific disciplines. These large systems create unprecedented application development challenges. Scalable correctness tools are cr ...http://www.ntis.gov/search/product.aspx?ABBR=DE20121030197Despite the wide array of frameworks proposed for the formal specification and analysis of privacy laws, there has been comparatively little work on expressing large fragments of actual privacy laws in these frameworks. We attempt to bridge this gap ...http://www.ntis.gov/search/product.aspx?ABBR=ADA571991Ocean waves are an important aspect of upper ocean dynamics, in particular on the shallow continental shelves and in coastal areas. The long-term objective of this work is to advance wave modeling capability in such coastal areas by improving model r ...http://www.ntis.gov/search/product.aspx?ABBR=ADA571540Nonparametric Bayesian methods are considered for recovery of imagery based upon compressive incomplete and/or noisy measurements. A truncated beta-Bernoulli process is employed to infer an appropriate dictionary for the data under test, and also for ...http://www.ntis.gov/search/product.aspx?ABBR=ADA571911No abstract available. ...http://www.ntis.gov/search/product.aspx?ABBR=ADA571729Craig (2001) hypothesized a 'killing zone'--a range of pilot total flight hours (TFH) from about 50-350, over which general aviation (GA) pilots are at greatest risk. The current work tested a number of candidate modeling functions on eight samples o ...http://www.ntis.gov/search/product.aspx?ABBR=ADA571652Organizations such as hospitals and banks that collect and use personal information are required to comply with privacy regulations like the Health Insurance Portability and Accountability Act (HIPAA) and the Gramm-Leach- Bliley Act (GLBA). With the ...http://www.ntis.gov/search/product.aspx?ABBR=ADA571959The long term goal of our QPE work is to: (1) quantitatively understand what the uncertainties are in low frequency (10-1500 Hz) acoustic propagation and noise that are caused by variable and complex oceanography and seabed structure, (2) determine t ...http://www.ntis.gov/search/product.aspx?ABBR=ADA571817No abstract available. ...http://www.ntis.gov/search/product.aspx?ABBR=ADA572034
