ABSTRACT: The objective of this proposal is to demonstrate the feasibility of a flexible, low-cost, integrated and sensitive broad spectrum optical property characterization system. We propose a hyperspectral imager designed for operation in the 300nm 2000nm spectral region with state-of-the-art spectral and spatial resolution through the use of a high density array of high finesse (F = 1000) tuna ...

ABSTRACT: The proposed VPHS (Vision Processor for Helmet Systems) is an advanced technology image processing engine that is designed to provide the image processing requirements of helmet mounted imagery systems. The VPHS will input high resolution image data from imaging sensors, process that data to yield enhanced visualization and output the imagery to operator displays. The VPHS will employ im ...

ABSTRACT: Remarkable advances in artificial intelligence (AI) and human-systems integration are providing aircrew with cockpit automation systems of unprecedented sophistication. Onboard intelligent assistants monitor the aircraft, interpret and carry out pilot commands, and advise the pilot (onboard or remote) as to aircraft and system status, mission progress, threats and alerts. Because pilots ...

ABSTRACT: This Phase I STTR project aims to develop a silicon friendly carbon nanotube field effect transistor platform technology with reduced contact resistance and wafer-scale aligned carbon nanotubes towards development of an L-band amplifier. Key innovation nuggets that will be developed include: 1) a wafer scalable process to deposit dense aligned arrays of high purity semiconducting and len ...

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: Carbon nanotubes (CNTs) have great potential for high performance RF applications. Theoretical study has shown that the electrical current in a CFET is intrinsically linear. Today, linearity is the underlying limitation in increasing the data transport densities of wireless networks. The complex modulation protocols used to achieve higher data rates requires linear amplifiers. Increasing ...

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 ...

ABSTRACT: Methodology for prediction of soot build-up in liquid film-cooled rocket engines will be incorporated into the CRUNCH CFD code, using a reduced-mechanism pyrolysis model and soot formation model developed at University of Virginia. A companion experimental program will be conducted at University of Virginia to collect data for calibration of the pyrolysis models for conditions and fuels ...

ABSTRACT: Designing an efficient and effective film cooling system to protect critical components of modern rocket engines requires a significant number of challenges to be addressed. Complicating the already difficult hydrodynamic challenges, thermal cracking of hydrocarbon fuels is always accompanied by coke formation. The coke deposits on the combustor and nozzle walls reduces heat fluxes and c ...

ABSTRACT: The proposed program is a joint effort between General Sciences, Inc. (GSI) and Drexel University. The proposed concept for Plasma Generation is based on the use of highly exothermic condensed phase reactions yielding temperatures considerably higher than the boiling points of candidate metal elements with residual energy to maximize their vapor yield and, with high probability to enter ...
