Abstract: An information-seeking dialogue system can be trained using a pipeline process having stages, or components, of passage retrieval (selecting passages relevant to a query from a corpus or knowledge base), re-ranking, and generating a response to the query based on one or more of the re-ranked passages. Each stage, or component, of the pipeline can be individually optimized based on ground truth data.

The inversion unit is suitable for generating an inverted standoff image and an inverted permittivity image for comparison with a composite image of the formation imaging unit.

Abstract: A bolt terminal mounted on a guide rail is provided. The bolt terminal comprises a housing (1), an integral nut (2), a screw (3), a connection component (4), and a wiring metal surface (5); one end of the screw is provided in the housing, the other end of the screw is located outside the housing, and the screw located outside the housing is to be connected to the integral nut fitted therewith; the wiring metal surface is provided on the interface between the screw and the housing; and the housing is to be connected to the guide rail via the connection component. The bolt terminal increases the requirement for powering the wirings, and the bolt terminal can be removed from the guide rail only by using a conventional screwdriver to lightly tap on a removal port. The screw is integrally connected to the housing by injection molding and thus there is no risk of the screw falling off, enabling higher reliability.

Abstract: Methods and systems for obtaining an electrical impedivity and/or resistivity image of a subterranean formation are provided. The electrical impedivity and/or resistivity image can be obtained by determining first formation impedivity data and second formation impedivity data. The first formation impedivity data can be based on a component of the measured impedance data orthogonal a downhole fluid impedance. The second formation impedivity data can be based on an amplitude of the measured impedance data. A combined formation impedivity data can be obtained by combining a portion of the first formation impedivity data based on a first formation impedivity determination process with a portion of the second formation impedivity data based on a second formation impedivity determination process. The electrical impedivity and/or resistivity image of the subterranean formation can then be obtained by using the combined formation impedivity data.

Abstract: Apparatus and methods for determining the rock solid (matrix) dielectric permittivity for subterranean rocks, such as carbonate rocks, are described. According to some embodiments, this is accomplished by linking the matrix permittivity to the detailed chemical composition of the rock. The linking function is defined by coefficients for each component that can be determined by inversion in a laboratory calibration process such that the function compensates for the permittivity contribution of rock components that may be undetectable through downhole logging procedures.

Abstract: Implementations are directed to predicting signal degradation at receivers used to display a programming service. The receivers capture signal strength data that is then transmitted to a processing location, which may be associated with a provider of the programming service. A signal degradation detector at the provider operates to predict whether or not a future unacceptable signal quality will occur within a time interval. The prediction may be based on a test quantity calculated from signals captured at the receiver and based on a figure of merit for the geographic locale in which the receiver is located. A maintenance call may be initiated for those receivers that have such a poor signal quality.

Abstract: Systems and methods for analysis of drilling cuttings are described. Complex permittivity is measured of rock cutting samples obtained during drilling operations. The origin of the cuttings is known by flow rate analysis in the drilling system. Various means can be used for rock cutting dielectric measurement. For example, the dielectric measurement can be made by matching the unknown permittivity of the medium to be analyzed to the permittivity of known liquid mixtures by successive saturation and looking for a “zero-contrast” measurement.
