Abstract: A new DP meter diagnostic system for wet gas flow builds on existing diagnostic techniques. Based on new diagnostic parameters and calculations derived from them, blocked pressure ports or impulse lines can be identified or wet gas established as the cause of an abnormal reading. Further diagnostic techniques can take advantage of the new diagnostic parameters to predict a liquid loading parameter, gas flow rate and fluid flow rate for wet gas flow.

Abstract: In an example embodiment, a process may create a disk for each point of the point cloud, where a size of the disk and the orientation of the disk are respectively based on a computed scale and a non-oriented normal. The process may insert each disk into a search structure that is queried to determine if one or more disks intersect the paths from a given point to each scanner in the point cloud. The process may create an output corresponding to each scanner in the point cloud, where each output includes the number of intersecting disks and the distance from the given point to the scanner. The process may implement a sorting algorithm to assign the given point to a scanner position. An application may utilize the assignment of each point in the point cloud to a scanner position to generate a high-resolution 3D mesh of a scene.

Abstract: Systems and methods are disclosed for identifying actual XIC peaks of compounds of interest from samples so that more accurate expected retention times and more accurate expected retention time windows can be calculated. In one system, an actual XIC peak is identified using standard samples. The ratio of the quantity of the compound of interest in any two different samples is known, so this ratios is compared to the intensities of the XIC peak calculated in the two samples to identify an actual XIC peak. In another system, an actual XIC peak is identified using information about other compounds of interest in a plurality of samples. It is known that the XIC peaks of compounds of interest in the same samples have a similar distribution of retention times across those samples, so the distributions of retention times of XIC peaks are compared to identify actual XIC peaks.

Abstract: Provided is a sensor in which a current sensor that detects a current of a power line as a change in a magnetic field and a voltage sensor that detects a voltage of the power line using capacitive coupling are integrally formed. The transmission of signals related to substantially the same sections is omitted in order to effectively compress an output signal from the sensor and an output signal from the voltage sensor. When the amplitude and phase of a fundamental wave which are estimated from the output signal from the sensor and the amplitude and phase of harmonics are encoded, the amplitude and phase of the harmonics are relativized with a value for the fundamental wave.

Abstract: Systems and methods for measuring turbulent gas flux using high-speed vertical wind speed measurements (e.g., on the order of 5-10 Hz or more frequently) and low-speed gas content measurements (e.g., on the order of 5 Hz or less frequently), without the need for the sophisticated and expensive high-speed hardware to separate gas samples (e.g., into accumulation bags) according to updrafts and downdrafts. A time series of high-speed vertical wind speed data is used as a guide to distinguish between updrafts and downdrafts. When vertical wind speed is upward (updraft), the low-speed gas content is recorded into a data structure in one location, or marked with one flag. When vertical wind speed is downward (downdraft), the low-speed gas content is recorded into a different location, or marked with a different flag. Eddy Accumulation or Relaxed Eddy Accumulation computations can be performed using the stored gas content data to determine gas flux.

Abstract: An elemental analysis of rock samples from outcrop sections or wells is performed. Data quality checks, data analysis, and filtering are performed on the rock samples, including de-spiking of elemental profiles and elemental ratios. First and second derivatives for the elemental profiles and the elemental ratios are calculated. Samples and depths that exceed thresholds are determined. The process is repeated for the elemental profiles and the elemental ratios that are related with boundary determination and carbonate or siliciclastic sediments. Additional filters are applied to at least a subset of the elemental profiles and elemental ratios that are related with boundary determination and carbonate or siliciclastic sediments to enhance the boundary identification. Possible boundaries in depths of the outcrop sections or wells are determined by summarizing the additionally filtered elemental profiles and the additionally filtered elemental ratios.
