Abstract: To present one or more content to users of an online system, the online system identifies a content evaluation pipeline including an order of a plurality of stages having one or more computer models for evaluating a likelihood of user interaction with a content item. The content evaluation pipeline selects a decreasing number of content items, from each stage of the order, according to the order of the stages in the order. The online system identifies a set of candidate modifications to one or more operational parameters of the content evaluation pipeline. For each candidate modification, the online system determines a compute time value and a content selection value. For a given amount of compute time, the online system optimizes the one or more operational parameters based on the determined content time value and the determined content selection value to increase the content selection value of the content evaluation pipeline.

Abstract: Oxygen from water can be efficiently and economically achieved via water electrolysis on antimony, nickel doped tin oxide (Sb,Ni—SnO2/Ti) anode using low DC power. As O2 is evolved, it will be quickly reduced by adjacent cobalt oxide doped carbon nanofilm (Co3O4—CNF/Ti) to hydrogen peroxide (H2O2) and electricity. In the said electricity generation, O2 is first formed in O2 evolution reaction (OER), then, electricity is generated in O2 reduction reaction (ORR). Both of anode and cathode are shared by OER and ORR, yet, the former consumes energy and the latter yields electricity. It is the cathode, a load and the anode that form an electricity-forming circuit. The said circuit relies on clean water to supply the fuel, O2, hence, it is designated as all-water fuel cell (AWFC). Supercapacitor is employed as the load for AWFC, and onboard purifiers are providers of clean water for AWFC.
