ABSTRACT: The U.S. Air Force has a need to develop a new class of advanced, wide field of view (WFOV) imaging sensors that sample the radiation field in multiple modes: spectral, temporal, polarization, and detailed object shape. These multimodal sensors are to be deployed on high altitude drones to enhance their intelligence, surveillance, and reconnaissance (ISR) capabilities. Smaller versions o ...

ABSTRACT:In this project we seek to transition major recent developments in the mathematics of model reduction to industrial grade computing applications in liquid rocket combustion instability. From the mathematical side, we are interested in unsteady nonlinear dynamical systems which exhibit limit-cycle behavior and large oscillations and potentially discontinuous solutions. From the application ...

ABSTRACT: The Tai-Yang Research Company (TYRC) of Tallahassee, FL in collaboration with Dr. Justin Schwartz of the North Carolina State University (NCSU) in Raleigh, NC propose in this Phase 2 effort to develop the critical technologies necessary for the implementation and operation of an airborne high temperature superconductor (HTS) superconducting magnetic energy storage (SMES) device with par ...

ABSTRACT: This Phase II STTR research proposal aims to demonstrate an antenna coupled phase modulator based on an Electro-optic (EO) polymer refilled slot photonic crystal waveguide (PCW) for operation in the Q band. The goal is to detect field strengths of 100uW/m^2 in an Intensity Modulation Direct Detection (IMDD) scheme using subwavelength antennas. The EO polymer is the SEO125 provided by Dr ...

ABSTRACT: aBeam Technologies, Inc. proposes a new printing technology for fabricating photonic devices. This nanofabrication process could potentially reduce to a single step, the fabrication of photonic crystals by direct imprinting on inorganic materials. The method is low cost and suitable for large-scale areas. In Phase I, the demonstration of feasibility of the method provides the basis for ...

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 ...

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

Experimental data from a number of DoD supported research programs have indicated that electrical systems capable of producing highly repetitive bursts of high voltage, fast risetime pulses are a critical enabling technology for applications tied to nonequilibrium physical processes, such as combustion, boundary layer flow, and the generation of high power EM waves. Recognizing the important role ...

In order to meet future needs for cost-effective high-capacity, secure telemetry systems, communication systems, smart weapons systems, UAVs, satellites, and other DoD platforms, further advances and innovations in digital-to-analog conversion must be achieved to support the migration to higher frequencies and operation in shared spectrum environments. This dictates a requirement for transmitters ...

In this program, HyPerComp and University of Michigan have teamedtogether to develop a high-order grid generator for Euler and viscousmeshes. The grid generator is based on HyPerComps successful generalpurpose CAD2Mesh software and is being integrated with HyPerCompsHDphysics and U. Michigans XFlow DG high-order solvers. High-order gridgeneration methods are being implemented to accurately capture ...
