Memory scrubbing is used to mitigate Single Event Upsets (SEUs) on susceptible devices. In the case of Field Programmable Gate Arrays (FPGAs), configuration memory scrubbing is generally used in conjunction with Triple Modular Redundancy (TMR) to increase reliability in spaceborne applications. Current solutions require a subsystem able to read and write from the configuration memory and retrie...

A mediator join index (MJI) is proposed to speed up Nway inter-database joins by reducing the amount of data transfer during evaluation. A family of algorithms, the Query Scrubbing Algorithms (QSA), are developed to maintainMJI and to evaluate queries usingMJI. QSA algorithms use query scrubbing to cope with update and query anomalies related to materialized views in the mediator context. Compa...

Caustic scrubbing is a technology that has been used for the removal of H2S and other acid species from gases in different industries for many years. Improvements in design and control strategies, favorable prices for caustic compared with other non-regenerable H2S scavenging chemicals, and the potential for sales value for the NaHS (sodium bisulfide) product have made caustic scrubbing an econ...

Anion-exchange membrane fuel cells offer the prospect of low-cost components thanks to their alkaline environment, yet they are plagued by carbonation electrolyte caused CO2 present in feed air. Now, an electrochemical method for scrubbing using a with mixed ionic–electronic conductivity offers potential remedy.

The AE&C single absorption–scrubbing process has long been an alternate to double absorption for the production of sulfuric acid. In recent years regulatory pressure to reduce SO2 emissions from sulfuric acid plants to 1.0-1.25 pounds of SO2 per ton of acid produced (to about 120 PPM) or less coupled with the increased value of energy has enhanced the desirability of the single absorption–scrub...
