ABSTRACT: In this project, we propose to develop the baseline process to form low source-drain contact resistance to the CNTs. This includes finding the right metal stack and annealing recipe to form good ohmic contact to the CNTs. The goal is to achieve a resistance less than 25 k at per nanotube contact. To reach such goal, we will leverage the interfacial dipole alignment of conjugated polyelec ...

ABSTRACT: Active control of the shock system in a scramjet engine isolator opens possibilities for enhanced engine performance and reduced engine weight by eliminating excess isolator design margin. A successful system will allow for maximum performance from a given engine configuration and will deliver range and efficiency that exceeds those possible using passive unstart control. Our approach is ...

ABSTRACT: The next-generation Global Positioning System (GPS) in congested and contested environments is expected to exploit Spectrum Holes (SH) in order to provide uninterrupted Position Navigation and Timing (PNT) service worldwide. Innoflight has teamed with the Air Force Institute of Technologys (AFITs) Autonomy and Navigation Technology (ANT) Center to develop a system based on cognitive radi ...

ABSTRACT: The overall objective of this project is to develop scalable simulation components that effectively model the meso-scale physics of heterogeneous energetic materials subject to dynamic shock loading including matrix debonding, void collapse, and damage due to crystal to crystal interactions, and bridges the meso-scale to the macro-scale for system scale simulations of the transition to d ...

ABSTRACT: A platform (PHA-fuse) for the stabilization of diagnostic and therapeutic reagents will be established based upon the polymer, polyhydroxyalkanoate (PHA). Fusions of a target molecule to PHA synthase, the enzyme responsible for PHA synthesis, will be constructed and used to catalyze the synthesis of PHA granules. These PHA granules will help stabilize the fused target molecules and elimi ...

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 ...

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: Analysis and Applications and Associates, Inc. (AAA) proposes to develop software that evaluates effects of the hypersonic flow environment on electro-optic/infrared optical systems and vehicles for specific hypersonic flight profiles. We propose a high fidelity definition of the near-field flow, using the latest CFD and turbulence modeling technologies, to determine the environment from ...

ABSTRACT: The proliferation of autonomous- and human-machine systems necessitates the creation of new tools for system design and evaluation. Key among these are simulation testbeds that support interactions between multiple warfighters and systems, and methods for creating and integrating intelligent agent models into simulation environments. We see a significant opportunity to advance the state ...
