The automatization of failing workflow handling is discussed. Implementation of a pipeline for DAQ and ML of error logs using big data analysis tools is available at github. Development of a prototype NLP model in Keras is explored.
Data collection was conducted from Phase III Project start date with completion of the NEPA review in Spring for 2009, through an intense characterization period during well drilling in the summer of 2009, to the start of injection December 1, 2009. During the early stages of injection, data collection was very intense. With staff onsite on 24 hour shifts until January, 2010. Detailed data collection was completed episodically during 2010, with an high injection rate in a tracer study completed during the spring of 2010, and then a repeat seismic survey with borehole gravity, VSP, cross-well and sonic logging conducted during the fall of 2010. By the report date at the end of 2011, data had been compiled and distributed to the team for analysis.
A summary and guide on how to modernize an organization's logging and monitoring infrastructure. Including why, key components and the steps to do so.
Downhole logging tools are commonly used to characterize multi-thousand-foot geothermal wells. The elevated temperatures, pressures, and harsh chemical environments present significant challenges for the long-term operation of these tools, especially when real-time data transmission to the surface is required via data cable lines. Teflon-based single or multi-conductor cables with grease-filled cable heads are typically used for downhole tools. However, over extended periods of operation, the gr
This dataset contains the event log table that provides 10-minute wind statistics from the scanning lidar at AWAKEN's site H. This is a good dataset to start from for people unfamiliar with the AWAKEN project.
This dataset contains the event log table that provides 10-minute wind statistics from the scanning lidar at AWAKEN's site A1. This is a good dataset to start from for people not too familiar with the AWAKEN project.

ARM Aerial Facility (AAF) Meteorological data from AIMMS-20 system logged on M300
Parameter dependence of phase and log amplitude scintillation - Signal statistics of spherical wave emitted by transmitter through intervening slab of irregularities
Counting rate meter compresses a wide range of data values, or decades of current. Silicon planar transistor, operating in the zero collector-base voltage mode, is used as a feedback element in an operational amplifier to obtain the log response.
Log-a-posteriori probability metric for use in sequential decoding
Log amplitude variance calculation methods compared in statistics of optical scintillation by application to measurements with laser
Digital log-linear companding technique for nonuniform quantization of speech and image signals
Fibrous insulation and refractory concrete are used for logs as well as fireproof walls, incinerator bricks, planters, and roof shingles. Insulation is lighter and more shock resistant than fireclay. Lightweight slag bonded with refractory concrete serves as aggregrate.
The landing site traverse log is presented for the Apollo 16 mission. EVA's 1, 2, and 3 are included.
