  • Publication number: 20150142685
    Abstract: Methods and apparatus having applicability to evaluation of hiring candidates. A method having applicability to evaluation of hiring candidates may include determining a first score for a first attribute of a hiring candidate and a second score for a second attribute of the hiring candidate, assigning the hiring candidate to a recruiting category based, at least in part, on the first and second scores, and controlling a display device to display an indicator associated with the hiring candidate, wherein a property of the indicator is based, at least in part, on the recruiting category to which the hiring candidate is assigned.

  • Publication number: 20050238549
    Abstract: An electronic control system for regulating operational parameters in a pollution removal system. The pollution removal system may contain at least one reaction zone connected to a source of gas and a sorbent feeder containing a supply of sorbent. The system may include a pollutant concentration sensor that measures the concentration of at least one target pollutant in a gas exiting a reaction zone, a differential pressure sensor that measures the differential pressure across a reaction zone, a sorbent feed rate controller that regulates sorbent feed rate to the reaction zone, and a controller in communication with these elements. The controller may use the measured values to adjust sorbent feeder rate to ensure that the target pollutant concentration in a gas exiting the reaction zone is within an acceptable range and that differential pressure across the reaction zone is no greater than a predetermined level.

  • Publication number: 20050074380
    Abstract: Methods and systems for processing metal oxides from metal containing solutions. Metal containing solutions are mixed with heated aqueous oxidizing solutions and processed in a continuous process reactor or batch processing system. Combinations of temperature, pressure, molarity, Eh value, and pH value of the mixed solution are monitored and adjusted so as to maintain solution conditions within a desired stability area during processing. This results in metal oxides having high or increased pollutant loading capacities and/or oxidation states. These metal oxides may be processed according to the invention to produce co-precipitated oxides of two or more metals, metal oxides incorporating foreign cations, metal oxides precipitated on active and inactive substrates, or combinations of any or all of these forms.
