Human ability to attend to a single voice in the presence of background interference is remarkable. If this could be imitated in practical technology it would be of great benefit for automatic speech recognition and other applications. Researchers at OhioState University have demonstrated computational methods for separating speech from interfering sounds that imitate human auditory processing, an ...

Agentase seeks Phase I STTR support to develop a kit of sensors for the detection of chemical weapons. The proposed effort builds upon an active program to develop chemical sensors based upon Agentase's patented enzyme-polymer biosensor technology. Workwill be conducted in two major areas. First, a prototype vesicant sensor will be crafted using similar approaches and techniques as those used i ...

This proposal proposes the synergistic integration of several methods for mining images, detecting, correlating and evaluating the existence of artifacts due to either hidden information or changes or target patterns or noise. The first method is based onthe Pixels Flow Functions (PFF) able to detect changes in images by projecting the pixel values vertically, horizontally and diagonally. These pr ...

The proposed research seeks to exploit ongoing research in the area of polymeric biocidal materials immobilized on solid surfaces such as textiles (e.g. cotton, 50/50 cotton/nylon blends, and polyester) to generate a protective shell fabric for aprotective suit that actively decontaminates biological species, an antimicrobial undergarment, or environmentally friendly mildewcides for cotton-based s ...

A software toolbox for closed loop flow control investigations will be developed. Our proposed toolbox integrates a well tested Computational Fluid Dynamics (CFD) solver (Cobalt) with feedback and controls specific software tools implemented in Matlab. Alldata exchange and output will use efficient open standard data formats to interface the results to most any commercial visualization package. Th ...

Cornerstone Research Group, Inc. and Liquid Crystal Institute of Kent State University jointly propose to develop and demonstrate material technologies enabling conductive liquid crystalline elastomer composite for aircraft gap treatment. This programwill design and experimentally characterize multiple candidate formulations to develop conductive elastomer materials tailored for this application. ...

The Air Force has recognized that the use of high temperature superconductors offers a great opportunity to reduce the weight and size of airborne power systems. There are several emerging airborne systems that will require large amounts of electricalpower while placing severe limitations on the size and weight of the equipment needed to generate and deliver this electrical power. This proposed ...

Plasmas have found wide application as sources of reactive radicals and ions for materials processing and treatment of flue gases. Operation at atmospheric pressure obviates the need for a vacuum system. Of the available types of plasma source used todissociate molecular gases at atmospheric pressure are arc discharges, which operate at neutral gas temperatures of up to 10,000 K; corona and dielec ...

We propose to develop a miniature a.c. driven, weakly-ionized plasma anemometer for measurements at hypersonic Mach numbers. The design will be based on earlier work by Vrebalovich (1954) who developed an a.c. glow-discharge anemometer and demonstrated itssensitivity to mean and dynamic mass-flux variations for Mach numbers between 1.3 and 4. The advantages of the plasma anemometer are that it req ...

The threat of biological attack can be mitigated by deployment of acost-effective bioaerosol sensor network. For U.S. forces inparticular, the high false alarm rate of the Biological AerosolWarning System is very costly. This project will demonstrate thefeasibility of a novel bioaerosol sampling system to enhance opticaltriggering. The sensitivity and selectivity of FT-IR instruments canprovide ra ...
