The objective of this project is to develop a multi-purpose combination type optical fiber sensor that enables simultaneous sensing of microstructural evolutions in the sensor materials and the environmental conditions such as pressure and temperature. It is very well known that materials subjected to fatigue and high temperature will go through microstructural changes such as plastic deformation, ...

Conventional computational docking typically takes a long time because it has a six-dimensional problem to solve - ligand orientation and ligand position - as well as conformational aspects. Reducing the dimensionality of the problem offers the opportunit

We propose to develop a computer based system for the online analysis of bio-behavioral signals associated with momentary loss of alertness. We will continue our development of bio-behavioral measures indicative of lapses in alertness. Our system will use only measures that can be obtained without attaching sensors to the operator. We will concentrate on monitoring the oculomotor system using came ...

The quench-protection strategy at 77 K identified in the Phase I STTR program involves depositing a thin film of a ceramic insulation having a large thermal conductivity at 77 K. Two ceramics were identified for this strategy, ZnO and Zn2GeO4, and in the Phase II STTR program the deposition properties of these ceramics will be explored (sputtering, ion-beam-assisted sputtering, pulsed laser depos ...

Cornerstone Research Group Inc. (CRG) and the University of Colorado at Boulder (CU-Boulder) will establish the fundamental understanding of materials and mechanical interaction necessary to develop modeling capabilities and fabrication processes for fastening morphing skins. During Phase I, CRG will conduct a broad array of multidisciplinary research ranging from biological systems to emerging me ...

Cornerstone Research Group, Inc. (CRG) and the University of Pittsburgh (Pitt) will develop light-activated composite materials technology. This development effort will enable the next generation of military vehicles to quickly and efficiently undergo dramatic reconfigurations as necessary to respond optimally to unpredictable warfare scenarios. Light-activated composite materials technology will ...

A highly efficient, very wide bandwidth, diamond studded micro helix TWT for operation at 95 GHz will be designed and fabricated by means of a novel application of solid state micro fabrication technology. Because of the nature of the fabrication process proposed here, this device can be built as a single TWT or just as readily as an array of TWTs. By spatially combining the power output of seve ...

The Phase I technical objectives of this program were to use existing lifetime based PSP technology and identify a combination of existing probes and binder that would provide a temperature-insensitive pressure sensitive paint (PSP). This was accomplished using the current lifetime-based systems that employ two-gate detection and by adding a second probe to the standard FIB pressure paint system. ...

During the Phase I effort, we propose to evaluate the feasibility of performing ultrafast-laser-based ballistic imaging for studying liquid hydrocarbon and oxygen injection characteristics for possible application in bi-propellant rocket engines. Ballistic imaging has the potential to circumvent the difficulties associated with propagating light through dense media. Through the combined use of ult ...

Field emission electron emitting arrays hold promise for use in high current density electron beam devices and can replace power consuming thermionic emitters. While single emitters can emit currents up to milliamps, large field emitter arrays are limited in total current due to non-uniformity and resulting instability problems. Solutions to these problems have been attempted using current limitin ...
