Abstract: Methods, apparatus, systems, and articles of manufacture to identify inconsistencies in audience measurement data are disclosed. Example apparatus disclosed herein are to compare ones of a first set of cumulative audience metrics with one or more limits based on a second set of event-level audience metrics to detect an inconsistency in at least one of the first set of cumulative audience metrics or the second set of event-level audience metrics. Disclosed example apparatus are further to generate a report of the inconsistency in the at least one of the first set of event-level audience metrics or the second set of cumulative audience metrics.

Abstract: A downhole turbine includes a plurality of fins. The plurality of fins have an exit angle that exerts a tangential force on the fin, which imparts a torque on a hub. The fins have an adjustable exit angle that changes in response to changes in the properties of a drilling fluid. The changing exit angle changes the tangential force, which changes the torque on the hub.

Abstract: A computer-implemented method for efficiently estimating the number of unique elements in a collection of elements comprises generating, via hash logic, hash values associated with the elements. The hash values specify bit positions within an array of bits. Hash values output from the hash logic conform to a geometric distribution such that bit positions of the array of bits corresponding to lower orders bits are more likely to be generated than bit positions corresponding to higher-order bits. Bits of the array of bits corresponding to the bit positions are set. The number of bits of the array of bits that are set is counted. Estimation logic estimates the number of unique elements of the collection of elements as a function of the number of bits of the array of bits that are set.

Abstract: A computer-implemented method for efficiently estimating the number of unique elements in a collection of elements comprises generating, via hash logic, hash values for each element of the collection of elements. The method further comprises specifying, in a sketch-frequency table, a set of discrete statistical values associated with the hash values and, for each discrete statistical value of the set of discrete statistical values, information indicative of a frequency at which binary representations of the hash values are associated with the discrete statistical value. The cardinality of the collection of elements is estimated based on the sketch-frequency table.

Abstract: Methods, apparatus, systems, and articles of manufacture are disclosed to estimate population reach from marginals. Example apparatus disclosed herein are to determine an audience relationship value based on first audience exposure values for a recorded audience of a media and a first de-duplicated audience value for the recorded audience of the media, determine bounds of a pseudo universe estimate of a population audience of the media based on the audience relationship value and second audience exposure values for the population audience of the media, and iteratively determine the pseudo universe estimate of the population audience and a second de-duplicated audience value for the population audience of the media based on the audience relationship value and the second audience exposure values, the pseudo universe estimate of the population audience to be within the bounds.

Abstract: The present invention relates to a tool (1) for separating a hair bundle (11) comprising a number of hair strands appropriate for receiving a hair treatment composition (15) for creating a hair bundle effect. The hair bundle (11) is received into a through hole (10) via a slit (50). The dimensions of the through hole (10) dictate the appropriate size of a hair bundle (11). In one aspect of the present invention, the tool (1) is substantially flat in order to prevent spillages of hair treatment composition (15) onto the scalp. A gripping layer (70) may extend upon at least a portion of the tool (1) for aiding the grip of the tool (1) to the hair bundle (11).

Abstract: A method of imparting hair strand effects may include identifying each of a plurality of hair strands to which to apply a hair strand effect product independently and individually, the plurality of hair strands associated with an illustration of at least one type of hair strand effects and one of a plurality of hair styles, and applying the product to each of the plurality of hair strands independently and individually subsequent to identifying the plurality of hair strands.
