摘要： There are provided a system and method for determining concentration level of a viewer by modeling an extent to which the viewer is at least one of engaged by and interested in displayed video content. The system includes a view status detector for extracting at least one viewer status feature with respect to the displayed video content, a content analyzer for extracting at least one content characteristic feature with respect to the displayed video content, and a feature comparer for comparing the viewer status and content characteristic features as a feature pair, to produce an estimate of a concentration level associated with the feature pair. The system additionally includes a combiner for combining concentration levels for different feature pairs into an overall concentration level of the viewer for the displayed content.

摘要： Mercury emission from a flue gas such as that generated by a coal fired power plant is controlled by injecting into the flue gas unburned carbon purified from ash such as fly ash or wood ash. The unburned carbon adsorbs the mercury and is later removed from the flue gas by a particle separator. The unburned carbon collected from ash is significantly lower in cost compared to activated carbon presently used in such a process. The unburned carbon is concentrated in the sorbent by one or more separation processes used to remove non-carbon particles from the fly ash. These processes include gravity separation, electrostatic separation, froth flotation, magnetic separation and size classification. Mercury adsorption is further increased by oxidation of the carbon surface.
