Abstract: A processing device receives a 3D model including a 3D crown component from a scan and a 3D root component from a template. The processing device receives a 2D x-ray image of the at least one tooth and generates a scan model representing an initial estimate of the one or more parameters of an x-ray imaging device that created the 2D x-ray image. The processing device further generates a 2D contour of the at least one tooth based on projecting the 3D model onto a plane using the scan model. The processing device overlays the 2D contour onto the 2D x-ray image. The processing device further adjusts the 2D contour to cause a first crown component of the 2D contour to approximately align to a second crown component of the 2D x-ray image. The processing then calibrates the scan model based on data obtained from adjusting the two-dimensional contour.

Abstract: Actual values of statistical signatures are computed. The actual values of statistical signatures correspond to analytical elements of a sample dataset. The computed actual values are discretized by assigning bucket values to the computed actual values. An aggregate score based on the assigned bucket values are computed. The assigned bucket values correspond to the analytical elements. The analytical elements of the sample dataset are ranked, based on the computed aggregate score. Combination of analytical elements is identified, and cumulative rank is computed based on the individual ranks of the analytical elements in the combination. The combinations of analytical elements are automatically displayed in a user interface associated with automatic visual discoveries.

Abstract: A pump apparatus has a downhole pump disposed in a wellbore and has motor at a surface of the wellbore, and the downhole pump is reciprocated in the wellbore by a rod string operatively moved by the motor. A card indicative of load and position of the downhole pump is generated using surface measurements and a wave equation model having a damping factor or two damping factors. Actual fluid load lines are determined from the downhole card for upstroke and downstroke of the downhole pump, and calculated fluid load lines from the load distribution of the downhole data. The actual fluid load lines are compared to the calculated fluid load lines so that at least one parameter of the pump apparatus can be modified based on the comparison. For example, the damping of the wave equation model can be adjusted so that another downhole card can be generated.
