Water expansion during freeze-thaw cycles can cause deterioration in concrete, leading to scaling, cracking, and crumbling over a period of years. Resistance to this damage is achieved with a system of voids formed by adding surfactants to the fresh concrete to stabilize air bubbles naturally entrained during mixing. The volume fraction, size, and spacing of these voids are critical. It is importa ...

Broken rails are a common cause of mainline derailments and a particular concern given the increasing use of our rail system for passenger traffic and petroleum products. The progressive nature of the defects provides an opportunity for early detection of cracks before they become significant enough to cause a derailment. Unfortunately, current inspection technology does not allow these inspection ...

The proliferation of sensitive DNA-based assays for detecting the presence of specific harmful, toxic or invasive organisms, as well as the simple reagent and instrumentation requirements for these assays has made widespread and more frequent testing for these different organisms possible. However, a frequent problem with such assays is the lack of available, well-quantified positive control stand ...

Ensuring the health of coastal marine ecosystems has emerged as one of the primary environmental concerns of this century. Frequent monitoring of water quality is required to establish baseline levels, allow identification of anomalies, and enable early detection of problems. Citizen science programs have been shown to be a highly effective method of monitoring water quality. Creare proposes to de ...

Commercially available unmanned aircraft systems (UASs) are not well designed to meet requirements for many atmospheric measurement applications, including deployment from ships, long endurance, and low cost. Multi-rotor UASs have recently gained popularity as a lowcost platform use in measurement and monitoring applications, but these systems have limited endurance and payload capabilities. Exist ...

Accurate marine weather nowcasts and forecasts are critical requirements for mariners to maintain situational awareness and ensure safe navigation for vessels, passengers, crew, and cargo. To best achieve this, reliable observations of atmospheric and sea conditions must be available at high spatial and temporal coverage. Unfortunately, existing approaches for marine weather observations are inade ...

As our nation’s dependence on reliable satellite navigation systems for precise Position, Navigation and Timing (PNT) applications increases, any errors/uncertainties or degradation of service will have significant life, safety, and economic impacts. Ionospheric ‘space weather’ is one of the largest sources of error in PNT applications that use the Global Navigation Satellite System (GNSS) s ...

HPD, a small business focused on development and commercialization of advanced instruments, sensors and research equipment, proposes to partner with NAOA on technology transfer and commercialization of the NO(y) Cavity Ring-Down Spectrometer for atmospheric research. Since our founding in 1993, HPD has collaborated with researchers at NAOA and other government, commercial and academic institutions ...

Hemorrhage is the leading cause of preventable death in combat, and damage control resuscitation (DCR) research has shown that plasma is a superior resuscitation fluid for severely injured, bleeding canine casualties. However, cold chain requirements make managing fresh frozen plasma (FFP) supply logistics difficult in austere environments. Limited supplies of freeze dried plasma (FDP) are curr ...

SATCOM On-The-Move (OTM) is one of the greatest operational and tactical advantages our troops have. The SATCOM terminals available pose a number of practical constraints resulting in less than universal usage. Traditional reflectors are high profile and difficult to integrate on aircraft and ground vehicles. The ability to maintain link during high-g maneuvers such as travelling over rough terr ...
