Abstract: The subject disclosure provides for a method of eccentricity correction of a borehole shape computation. The method includes deploying a caliper tool into a borehole penetrating a subterranean formation and acquiring field measurements with the deployed caliper tool. The method includes applying, in a processor circuit, an eccentricity correction algorithm to one or more standoff samples from the obtained field measurements, wherein the eccentricity correction algorithm produces a shape fitted curve that represents a measured borehole with a least number of points outside of the shape fitted curve and a least amount of error. The method includes determining eccentricity-corrected borehole coordinates with the applied eccentricity correction algorithm and determining a borehole shape from the eccentricity-corrected borehole coordinates. The method includes determining tool location coordinates relative to the borehole with the determined borehole shape.

Abstract: This disclosure relates generally to system and method for time series prediction using a sparse recurrent mixture density network (RMDN), such as sparse LSTM-MDN and a sparse ED-MDN, for accurate forecasting of a high variability time series. The disclosed sparse RMDN has the ability to handle high-dimensional input features, capture trend shifts and high variability present in the data, and provide a confidence estimate of the forecast. A high-dimensional time series data is passed through a feedforward layer, which performs dimensionality reduction in an unsupervised manner by inducing sparsity on weights of the feedforward layer. The resultant low-dimensional time series is fed through recurrent layers to capture temporal patterns. These recurrent layers also aid in learning latent representation of the input data. Thereafter, a mixture density network (MDN) is used to model the variability and trend shifts present in the input and it also estimates the confidence of the predictions.

The mobile device may provide the payment token to a contactless payment terminal (CPT) associated with a merchant, during a purchase transaction involving a product provided by the merchant, where the mobile device may communicate the payment token to the CPT over a local network that is different from the first network such that connectivity between the mobile device and the first network is not required.

Abstract: A compromised data exchange system extracts data from websites using a crawler, detects portions within the extracted data that resemble personally identifying information (PII) data based on PII data patterns using a risk assessment module, and compares a detected portion to data within a database of disassociated compromised PII data to determine a match using the risk assessment module. A risk score may be assigned to a data item within the database in response to determining the match. In some embodiments, URL data may also be detected in the extracted data. The detected URL data represents further web sites that can be automatically crawled by the system to detect further PII data.

Abstract: This disclosure relates to non-contact inspection of material for identifying and estimate composition of a material under inspection. Traditionally, material inspection is an invasive process involving contact based approaches.

The present disclosure addresses this technical problem by providing a Continuous Wave radar-based approach that is based on absolute slope at extrema points on the reflected signal from the material under inspection.
