Abstract: A computer-implemented method for selecting a digital content, comprising: receiving a plurality of samples, each comprises a request having a plurality of values of a plurality of attributes, and associated with a success value for a Bernoulli distributed event having a campaign and a bid rate (BR) of the campaign; clustering the plurality of samples in a plurality of homogenous nodes according to respective plurality of values; identifying a group campaign with a highest valuation for each one of the plurality of nodes using triangular approximation of the Bernoulli distribution of events in the node; receiving a query from a device including a plurality of other values of the plurality of attributes; selecting one of the plurality of nodes; selecting a digital content of the group campaign with highest valuation identified for the selected node; and generating a response to the query including the selected content.

Abstract: A glass tempering furnace having a chamber, rollers extending laterally within a chamber to form a transport surface for the plate glass, radiant coils positioned along the bottom of the chamber underneath the rollers, a plurality of spaced nozzle assemblies arranged in lateral side-by-side fashion within the chamber above the rollers, and fans coupled to the nozzle assemblies to draw heated air from the chamber and force the heated air onto the top surface of the plate glass. Heating elements, preferably electrically heated rods, extend between each of the nozzle assemblies and are positioned within the return path of the heated air after it is flowed onto the plate glass surface. The air then rebounds from the glass plate prior to the air again being drawn up into the fan and blown back down onto the glass. Air is then again drawn from the furnace chamber and forced through ducting to a nozzle assembly.
