Abstract: One variation of a method for quantifying user engagement includes: serving a digital advertisement to a mobile device; recording a first proportion of pixels of the digital advertisement rendered on a display of the mobile device during a first sampling period; recording a second proportion of pixels of the digital advertisement rendered on the display of the mobile device during a second sampling period offset in time from the first sampling period; calculating a cumulative pixel exposure of the digital advertisement at the mobile device based on a combination of a first product of the first proportion of pixels and a duration of the first sampling period and a second product of the second proportion of pixels and a duration of the second sampling period; and storing the cumulative pixel exposure as an engagement metric for a user consuming the digital advertisement at the mobile device.

Abstract: The invention relates to a method of characterizing and of quantifying carbon from a superficial deposit, wherein a sample of the deposit is subjected to heating in an inert atmosphere, the sample residue is subjected to heating in an oxidizing atmosphere, and quantities of HC, CO and CO2 released during heating, from which standard parameters TOC and MinC, and a ratio between mineral carbon and total carbon of the sample are determined, are measured. If the ratio is non-zero, the organic carbon content is equal to the sum of TOC and of a percentage of TOC ranging between 4 and 12%, and the mineral carbon content is equal to MinC minus this percentage of TOC. If the ratio is zero, the mineral carbon content is zero and the organic carbon content is equal to the sum of TOC and MinC.

Abstract: One variation of a method for serving interactive content to a user includes, at a visual element inserted into a document accessed by a computing device: loading a first frame from a digital video; in response to a scroll-down event that moves the visual element upward from a bottom of a window rendered on the computing device toward a top of the window, seeking from the first frame through a subset of frames in the digital video in a first direction at a rate corresponding to a scroll rate of the scroll-down event, the subset of frames spanning a duration of the digital video corresponding to a length of the scroll-down event; and, in response to termination of the scroll-down event with the visual element remaining in view within the window, playing the digital video forward from a last frame in the subset of frames in the digital video.
