Carbon nanotubes, have extraordinary mechanical properties, but these properties are difficult to manifest in composites, due to their limited interfacial bonding, and therefore the inability to transfer loads from a polymer matrix. Chemical functionalization of the nanotube surface is required to improve the interfacial load transfer, but functionalization may degrade the tensile properties of th ...

The objective of the proposed research is to use chemistry to modify single-walled carbon nanotubes (SWNTs) and engineer the interfacial interaction with polymers to synthesize composite materials with enhanced mechanical, electrical and thermal properties. We will conduct research on the synthesis and properties characterization of SWNT-reinforced composites based on epoxies and vinyl esters. Our ...

In this proposal we support the development of a hypoxia test battery by designing and developing a domain general tool suite for processing, synchronizing, and evaluating data from cognitive, behavioral, and physiological measures.The proposed Griffon Tool Suite addresses many of the practical requirements demanded by a flexible test battery. The effort falls into three major thrusts.First, we pr ...

Technology continues to advance at faster and faster rates. Often new technology is created with little regard for the impact to the humans who must use this technology. One new technology the Navy is considering using is autostereographic displays, which permit users to see a true 3D image without wearing cumbersome glasses. Aptima and its partner, Dr. Dirk Reiners of Iowa State University, will ...

This proposal is to develop a Handoff Training for Combat Casualty Care (HTC3) Framework.Training is the crux of the handoff problem today. Patient handoffs are a crucial part of casualty care, both in military and civilian environments; and today handoffs are being performed in less than optimal fashion, with ineffective communications accounting for 80% of the handoff errors. Our new HTC3 Framew ...

Target detection and recognition is a challenging problem because of changes in appearance, viewing direction, occlusion and other covariates. Systems that can accurately and efficiently detect and track objects can provide several benefits in surveillance, monitoring and other applications. As part of this effort, we propose to develop a robust learning-based approach to detect, track and recogni ...

We propose to develop high-fidelity numerical simulation tools to be used in the analysis and assessment of bone conduction of sound in the human head and the desigh of noise protection devices. The proposed approach utilizes boundary and volumetric integral equation methods, and will constitute an extension of our currently developed approach from acoustics to coupled elasticity-theory and acou ...

Recent terrorist activities and law-enforcement situations involving hostage situations underscore the need for effective through-the-wall surveillance (TWS). Current building interior imaging systems are based on short-pulse waveforms, which are easily recognizable by the intelligent adversary who may employ countermeasures to confound detection. We propose a coherent continuous-wave ultrawideban ...

CCR will team with SRI International to develop high current field emission arrays for high power RF source. The Phase I program will utilize a combination of analytical calculation, computer simulation, and experimental verification to study various approaches and determine their effectiveness in achieving the program goals. The technical objective of the Phase I program will be to develop field ...

A new approach is proposed for high fidelity analysis of aeroelastic characteristics of integrally bladed rotors. This new multiscale approach for nonequilibrium flow path analysis will yield high fidelity solutions including all turbulence scales at a fraction of the computational cost of RANS. Integration of this advanced capability within an existing multidisciplinary, multifidelity, transien ...
