We propose a high performance library of signal processing tools that incorporate a newly developed technique known as fluctuation enhanced sensing (FES) to enhance the novel microsensor developed at NIST. Our goal is to improve the performance of the NIST sensor from two angles. One is to apply our existing proven algorithms to the NIST data. The other one is to incorporate advanced FES concept t ...

G2 proposes to develop an intuitive, interactive SCAP content creation and editing utility that will provide a user-friendly operating environment. The promise of security automation offers the opportunity for great advances in software assurance, security governance/reporting, and ongoing monitoring activities. Hindering that promise is the fact that current data exchange protocols are cumbersome ...

Historical methods of reliability assessment are less and less effective as device sizes shrink. Larger sample sizes and longer duration tests are increasingly needed. At the same time, efforts to continue scaling semiconductors to ever smaller geometries is leading to an explosion of new device structures, materials and processes. The cost of testing these innovations is becoming a major barrier ...

ABSTRACT: The test and evaluation (T & E) mission in complex test facilities results in large amounts of data. Moreover, the data may have different characteristics, including images from particle image velocimetry data, air flow data, etc. Finally, some of the data may come from a network of similar sensors. We propose a novel, flexible, and comprehensive system for mission prioritized lossless ...

ABSTRACT: The objective of this proposal is to demonstrate the feasibility of automating the identification, processing, and storage of the most critical and pertinent data collected by a wide variety of complex sensors using a patented cloud computing methodology designed to permit the greatest flexibility and system efficiency. This novel architecture uses a revolutionary but simple idea tha ...

ABSTRACT: It is very challenging to secure applications in today"s networked computer system where applications inherently share various resources and information. In this proposal, we propose a novel approach, called policy guided isolation and strategically shielded exposure, to protect applications in network environments. Our approach combines virtualization techniques with a Policy Machine t ...

ABSTRACT: Efficiency of solar cells is typically low reaching on the order of 10% for commercially available cells. Furthermore, efficiency decreases by 0.5% for every degree increase in operating temperature. In order to increase the efficiency of the conversion of solar radiation per unit area to electricity it becomes advantageous to combine the solar cell with a thermal energy harvester. Acti ...

ABSTRACT: The behavior of the Chalcogenide based ion-conducting memristor lends itself for use as an element in a simple neuromorphic computing circuit. The reaction of a circuit to an external stimulus may be the result of its ability to learn from previous similar, yet unrelated exposures to environmental stimulus. A highly specialized variation of the memristor, previously developed by the Ad ...

ABSTRACT: The leading errors in computing future positions of satellites in Low Earth Orbit (LEO) are generally due to inaccuracies in the thermospheric density and the prediction thereof. The use of Dynamic Calibration Atmosphere (DCA) has significantly reduced these traditional sources of error and variations seen in ballistic coefficients can now be attributed to unmodeled satellite frontal ar ...

ABSTRACT: Recent improvements in atmospheric density modeling now provide more confidence in spacecraft ballistic coefficient (BC) estimations, which were previously corrupted by large errors in density. Without attitude knowledge, forecasting the true BC for accurate future state and uncertainty predictions (for non-spherical satellites) remains elusive. In this project, our objective is to im ...
