Comprehensive on-site radiological survey of processed sludge drilled materials extracted from the oil and gas production activities in the Utica and Marcellus Shale in Ohio has been conducted with a shielded isotopic identifier incorporating an advanced patented algorithmic processor to measure low-activity levels in compliance with environmental standards.
Maintenance for wind turbines, particularly offshore turbines, presents a significant cost component to wind farm operators. The main bearing, which supports the low-speed shaft, is one of the major wind turbine system components. Since maintenance is confined to suitable weather windows, which are unpredictable, there is a need for decision support tools… (More)
The current Air/Ground mobile technology used for ATN/OSI is VDL Mode-2. In time, other mobile technologies will be used such as Satellite Communications, for example possibly INMARSAT and Iridium, and other ground based systems, for example AeroMACS. These mobile technologies already support networking using the IP protocol suite. ICAO 9896 has been… (More)
Flowback and produced wastewaters from unconventional hydraulic fracturing during oil and gas explorations typically brings to the surface Naturally Occurring Radioactive Materials (NORM), predominantly radioisotopes from the U238 and Th232 decay chains. Traditionally, radiological sampling are performed by sending collected small samples for laboratory… (More)
This paper evaluates the use of System Wide Information Management (SWIM) to support sharing of safety ATM data link information from Controller Pilot Data Link Communications (CPDLC) and Automatic Dependent Surveillance (ADS), in addition to advisory information. The convergence of both advisory and safety critical information into IP-based (including… (More)
