Abstract:Currently, there are over 10,000 MRI scanners used in the US alone. US citizens today are mobile and many times medical treatments may require MRI scans from several different facilities. Images from MRI scanners can also drift over time. There is a tremendous need for all medical imaging scanners… more
Abstract:In Phase I, our research team set forth an innovative design of and enabling techniques for universal plug and play navigation (UPNAV) that reconfigures itself on-the-fly as aiding sensors are connected to and disconnected from the system without the need for system redesign and software recompiling… more
Abstract:The proposed Phase I program will develop a Bayesian framework for modeling and predicting track uncertainty and performance as a function of OCs and integrate this framework with algorithms for tracking vehicles in WAMI. The proposed Performance and Uncertainty Modeling and Prediction for Tracking… more
Abstract:Situational awareness is paramount when conducting operations in potentially hostile terrain. Vehicle operators must focus on multiple tasks simultaneously: navigation, collision avoidance, location of possible IED threats, and identification of dismount threats. Fatigue and distractions affect… more
Abstract:Fully automated approaches to target detection are efficient at processing large amounts of data but often rely heavily on the training data and the model employed. Training data and modeling assumptions can be violated in the operational environments where the algorithms are applied. Alternatively,… more
Abstract: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… more
Abstract:We propose novel and real-time smart software tools to process spectroscopy data. Material abundance or compositional maps will be generated for rover guidance, sample selection, and other scientific missions. First, we propose a novel anomaly detector called clustered kernel Reed-Xiaoli (CKRX)… more
Abstract:Some commercial auscultation devices pick up all sounds without filtering out the background noise. Although the electronic stethoscopes made by 3M and Thinklab have some simple built-in filters, those filters cannot differentiate important internal body sounds from interfering background noise.… more
Abstract: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… more
Abstract:Matrix completion has many applications such as link recovery, data mining, image reconstruction, etc. We propose a novel algorithm to solve the above mentioned matrix completion problem. In particular, we have derived a novel framework to approximate the rank by another function. This novel… more
Abstract:Advanced Mission Management (AMM) requires Automated Mission Planning (AMP) capability that, in turn, dictates the need to have tools for intelligent fusion of multi-source data for situational awareness, human-like reasoning for optimal mission plans (course-of-action (COA)) determination, and… more
Abstract:We propose a novel, high performance, and standalone system for improving close air support (CAS) effectiveness. We have several important elements. First, we propose a standalone noise cancellation device (NCD) that can be inserted between the handset and the transceiver. That is, the handset… more
Abstract:Coherent distributed active sonar systems are of great importance for the prosecution of modern day underwater threats. Existing systems typically employ sensor management strategies that underutilize the full capabilities of the multistatic sensor field. If the distributed multistatic field could… more
Abstract:Traditional tradeoff methodologies have not permitted an easy, efficient and analytically-based means for trading between traditional survivability areas and other selected non-traditional survivability technology functional areas such as lethality, mobility, situational awareness, blast mitigation… more
Abstract:DESCRIPTION (provided by applicant): Rosacea is a chronic dermatological condition characterized by flushing, erythema, papules, pustules, inflammatory nodules and telangiectasia. Although disease etiology remains unclear, skin inflammation has been identified as the main contributor to disease… more
Abstract:Silatronix has developed novel organosilicon compounds that can be used as drop-in replacements for conventional carbonate electrolytes in lithium-ion cells. These organosilicon electrolytes have very high flash points and have demonstrated superior stability and safety characteristics. In the… more
Abstract:ABSTRACT: Silicon Space Technology (SST) proposes designing a customized 130nm Metal Programmable System on a Chip (MPSoC) slice based upon our 130nm fabric that can be used to implement multi-million gate designs. The slice would have embedded IP sub-circuits and IO interfaces that can be used to… more
Abstract:Recent clinical research has established that this ratio is indicative of the activity of the CYP2A6 enzyme that metabolises nicotine. Nicotine is metabolized to COT and then to 3HC. People with high activity of this enzyme, clear nicotine faster and henceneed more nicotine to maintain the addiction… more
Abstract:DESCRIPTION (provided by applicant): This proposal describes Phase II of the development of a rapid point-of-care test kit for the direct measurement of bacteriuria as a diagnostic for urinary tract infections (UTIs). While bacteriuria at a level of 105 CFU/ml is the gold standard for UTI diagnosis,… more
Abstract:DESCRIPTION (provided by applicant): Anterior cruciate ligament (ACL) injuries are a significant problem for athletes, and women in particular.

There are several categories such as “By Agency”, “By Year”, “By State” etc.
Select a checkbox within a category to refine your search results.
Each of your selections is listed in the “Narrow Search Filters” bar. You can uncheck these selections to remove them.
Search for Either Criteria
When you select multiple values within a category, the results will include values that match either of the selections.
For example, selecting “2005” and “2007” in the “By Year” category will display results that include either 2005 OR 2007 in the results.
Narrowing the Search Results
You can refine your search results across categories. To narrow down your results, select multiple values across different categories. The results will only include values that match the selections across the categories.
For example, selecting “2005” in the “By Year” category and “NASA” in the “By Agency” category will only display the results that contain both “2005” AND “NASA” in the results.
