The operating point of a chemical process is usually computed by optimizing a steady-state objective function, e.g. the profit, subject to the steady-state characteristics of the plant.
Control of periodically operated reactors has in common with control of reactors operating at steady state the objective of minimizing the effect of disturbances on an objective function such as the cost of a product or the deviation of an outlet concentration of a pollutant from a statuary target.
Note 1: Definition of "Wild-type" strains in the context of OptFlux simulations We use the term wild-type strain/organism in this study meaning strains that have a (approximately) known pre-definable steady-state flux objective function (e.g. biomass formation rate as in case of FBA).
We are making steady progress toward that objective and appreciate the monitor's ongoing work".
"We are making steady progress toward that objective and appreciate the monitor's ongoing work," Levey said.
After using the flight controls to steady the airplane, the objective normally would have been to bring it back to its previous orientation -- in this case climbing and banking slightly to the left in its first turn out of Kennedy.
The objective of steady state optimisation is to minimise the recycle rate with minimum cost for continuous processes.
We use a greedy selection algorithm at first and see a steady increase in the objective function ("number of hits") during the evolution process,.
"There's been a steady rollback of our objectives of what's good enough in Afghanistan," said Vali Nasr, a former senior State Department official who worked on Afghanistan and Pakistan and is the dean of the School of Advanced International Studies at Johns Hopkins University.
This means to search for high response at peak, low delay to peak, but also a low response at steady-state (see Section "Objective function" and Figure 3A).
