In this Phase I effort our team, a collaboration between Traycer Diagnostic Systems and The University of Notre Dame, proposes to develop a single pixel detector of terahertz frequency electromagnetic radiation. The devices we propose are AlN/GaN high electron mobility transistors which, via the excitation of plasma waves in the device channel, exhibit a nonresonant broadband and resonant respons ...

Exposure to light at critical phases of the circadian cycle is the main stimulus that entrains circadian rhythms.  Previous work has concluded that exposure of humans to bright light for an hour or more at the right phase of the circadian cycle produces significant phase shifts of circadian rhythms speeding recovery from jet-lag, and optimizing cognitive functionality and restorative sleep.  Our ...

This proposal is concerned with the development of a novel failure initiation and progressive failure analysis (PFA) modeling method for advanced composite structures. The laminate is modeled as a collection of degrading lamina within the framework of lamination theory and executed using user defined subroutines through a commercial finite element software package. In the proposed approach, design ...

The Nanoparticle Field Extraction Thruster (NanoFET) is being developed as a high thrust-to-power, highly compact, variable specific impulse electric propulsion device especially for micro-satellite applications. NanoFET provides thrust by extracting and charging nanometer to micron-sized conducting particles (e.g., spheres) fed from a dry reservoir and accelerating them electrostatically. This te ...

The objective of this program is to build upon many decades of experience with magnetic flowmeters to develop a next-generation system to measure the burning surface admittance of high-energy-density solid propellants at high frequencies and pressures. Using the results of research on solid propellant rocket motor combustion instability from the past fifty years, one can directly measure the acou ...

In this Phase I STTR program, the project team will develop a mathematical model for the hydrogen permeation inhibiting efficiency for various metals and alloys.  Experiments based on the Devanathan-Stachurski method will be used to determine the models kinetic parameters, which control hydrogen permeation.  The hydrogen entry efficiency and effectiveness of electrodeposited, nanostructured laye ...

This proposal covers investigating and optimizing superconductor cable configuration designs and various cooling methods for lightweight airborne power cables. During this program we will be modeling several types of superconducting cable configurations and design parameters for optimizing the system weight and volume as a function of cable length.  We will study the trade-offs among the influenc ...

High performance reconfigurable computing (HPRC) is an expanding technology offering workstations and small clusters performance levels previously reserved for large-scale systems populating the Supercomputing 500 list. However, the lack of open-source libraries of generically applicable numeric methods (i.e. BLAS, LAPACK, Numeric Recipes, etc.) optimized for FPGA embodiment has hindered adoption ...

In phase II we will develop a prototype high power time domain terahertz (TD-THz) pulse source with a 1 milliwatt average output based on our Phase I approach.    This source will be compatible with conventional time domain terahertz spectroscopy and imaging instrumentation, but extend the output power greater than a 1000 times the 1 microwatt typically generated by conventional systems.  TD-T ...

RNET Technologies, Inc., (RNET), a small business located in Dayton, OH, is responding to the STTR in collaboration with Prof. Bradley Duncan and Prof. Joe Haus of the University of Dayton (UD). The solicitation states that the objective of this STTR is to develop sub-aperture based EO imaging systems capable of being near conformal and of compensating for atmospheric effects. It also states that ...
