The proposed algorithms include novel feature clustering techniques to enable effective characterization of intra-class and inter-class appearance variations in datasets containin ...

ABSTRACT: Toyon Research Corp. and the Penn State Univ. propose research and development of innovative algorithms for classifying objects and activities observed in high-dimensional data, including video and hyperspectral imagery. The proposed algorithms include novel feature clustering techniques to enable effective characterization of intra-class and inter-class appearance variations in datasets ...

ABSTRACT: An unseeded measurement technique is proposed for simultaneous spatially-resolved measurements of density, temperature, and velocity in hypersonic wind tunnel flows with the future potential for time-resolved measurement capability. A variant of filtered Rayleigh scattering (FRS) will be developed that takes advantage of unique monotonic relationships between molecular vapor cell filter ...

ABSTRACT: Over the past decade, there has been a sustained interest in Global Positioning System (GPS) denied navigation technologies for unmanned aircraft systems (UAS). This has been primarily due to the well accepted susceptibility of GPS signals to intentional jamming or unintentional interference and blockage. One of the challenging problems in GPS-denied navigation is handing off moving targ ...

Unmanned aircraft systems (UAS) are increasingly seen as a cornerstone in developing the future Defense infrastructure and it is critical that they collaborate efficiently and execute complex missions in denied environments. Although great progress has been made in GPS-denied navigation, the target handoff problem in GPS-denied environments has not been extensively studied. In this problem, a trac ...

ABSTRACT: Speech recognition technology is in wide use today and has been successfully integrated in a number of applications. Most of these applications require a microphone located near the talker. However, when a distant microphone is used where the speaker is at some distance from the microphone as in a hands-free communication, or in a meeting room, there is a major problem with the captured ...

Automatic speech recognition (ASR) technology is in wide use today and has been successfully integrated into a number of applications. Although there are also many potential applications for automatic speaker identification (SID), SID accuracy rates are generally not sufficient for widespread use in practical applications. For high accuracy ASR and SID, the microphone must be located near the talk ...

ABSTRACT: The effects of fatigue and exhaustion can have significant effects on the capabilities of personnel throughout the military and civilian sectors. Current methods to evaluate and reduce the effects of severe fatigue and exhaustion include self-reporting, assessment using simple cognitive tests and exercises, and the implementation of fatigue management programs. Detection of chemical ind ...

Commercially-derived telescope systems, consisting mostly of commercially available components assembled to optimally meet space surveillance goals, stand ready to temporarily replace, supplement and/or augment existing optical surveillance systems. In t...

ABSTRACT: The United States relies heavily on force multiplying, space-based navigation, communications and intelligence, surveillance and reconnaissance (ISR) capabilities. These satellites populate all orbital regimes including low-earth orbit (LEO), medium earth orbit (MEO) and geosynchronous earth orbit (GEO) and frequently require complex ground station network support requirements. Miltary ...
