A system to control the emissions of a fluid stream in a cyclical fashion utilizing an up-flow cycle and a down-flow cycle. The system decomposes at least selected queries to generate multiple subqueries for application, in parallel, to the DBMS, in lieu of the intercepted query. The array of sensors can provide data corresponding to at least one of a degree of cure of the protective coating, a health of the cured protective coating, and a corrosion rate of the engineered structure at each of the sensors. Correction values for the control parameters are determined from the zeroth- andor first-order local components of the development and are taken into account in the control of the magnetic resonance apparatus for magnetic resonance image acquisition. A second layer of insulation surrounds the second electrical conductor. The second compressed air bleed arrangement bleeds a second flow of compressed air from one or more lower pressure stages of the compressor section.
