Fracture toughness is the material parameter that, along with applied loading and flaw geometry, dictates the critical crack size, and therefore controls the flaw size that must be detected during inspections. A major challenge facing pipeline operators is that many pipelines are old, making their structural integrity uncertain, and that material pedigree of the pipeline steel is unknown. Therefor ...

22 million workers go to work each day in damaging noise.Noise-induced hearing loss remains a problem in US industry and in the US military despite our best preventative efforts.A significant roadblock in preventing hearing loss is the lack of an accurate quantification of personal exposure.Potential risk is currently determined by measuring cumulative noise exposure using personal noise dosimeter ...

To extend the usage of tourniquets during a war, Advanced Cooling Technologies, Inc. (ACT) proposes to develop an innovative limb cooling device charged with two-phase working fluid, which is able to rapidly cool down the limb and keep the limb temperature within the range at 10-15C for 24 hours. The limb cooling device will be conformable and easy-to-apply on both upper and lower extremities. A m ...

This project will achieve a field-deployable system to estimate circadian phase. Our approach involves the use of minimally-invasive sensors suitable for use in operational environments to continuously monitor physiological parameters associated with sleep timing, sleep quality, and circadian phase. Sensor measurements of circadian phase will be combined with a predictive model of circadian phase ...

NDT of Fracture Toughness for Pipeline Steels 3/16/2018 Ultrasound-based technology to nondestructively determine fracture toughness of pipeline steels will be developed. Fracture toughness is the material parameter that, along with applied loading and flaw geometry, dictates the critical crack size, and therefore controls the flaw size that must be detected during inspections. A major challeng ...

Nokomis proposes to develop a real-time microwave spectroscopy device to measure the health and viability of 2D and 3D cell cultures. Utilizing a combination of spectroscopic techniques, Nokomis will utilize existing knowledge of dielectric properties of cell cultures and how they relate to varied parameters of the culture to deliver an in-line, non-destructive measurement device. The proposed wor ...

The objective of this Phase II project is to translate the proof of concept prototype developed in Phase I towards practical implementation. The focus will be on transtibial prosthetic legs. The Phase I design will be improved for bio-mechanical functionality, reliability and cost effectiveness. Full size and full load scale products will be experimentally tested and evaluated with transtibial amp ...

The Aerial Reconfigurable Embedded System (ARES) allows a large payload to be independently configured to meet the mission needs. This Phase II effort will develop a mission payload for use on the DARPA ARES Technology Demonstrator for a Casualty Evacuation (CASEVAC) Module.Under this effort the PiAC team will evaluate the existing pod structure to assess the integration of a single litter, medica ...

TECHNICAL ABSTRACT: We propose developing a new observational capability for measuring upper atmosphere (20-Km to 200-Km+ altitude) wind and temperature dynamics, based on Doppler imaging of Limb concentrations of NO, N2O, and CO2 called the Doppler Wind Temperature Sounder. The principle of operation is that by measuring the Doppler shift of trace gases created by the differential velocity betwee ...

Searching for street parking, a behavior known as cruising for parking, leads to excess congestion and pollution. Many recent smart parking interventions have attempted to address this issue, but the problem of effectively detecting and measuring cruising remains largely unsolved. The goal of this work is to develop methods to detect and measure cruising for parking and its effects on congestion u ...
