The phrase "a certain operating" is correct and usable in written English.
It can be used when referring to a specific operation or process that is not explicitly named or defined.
Example: "In the context of software development, a certain operating system may have unique features that enhance performance."
Alternatives: "a specific operation" or "a particular process".
In some of these controllers, the control parameters are tuned once for a certain operating point and remain unaltered, even when the operating conditions change, unless the operator changes it manually.
With a certain operating time and ink coverage, the percentage weight loss of the pulp yield after deinking treatment has been lower by applying electrostatic force.
However, each of them is only applicable for a given membrane type, given feed salinity over a certain operating pressure range.
The safeguarding methodology currently used in the chemical industry is based on controlling the instantaneous values of the process state variables within a certain operating window, the process being brought to shut-down when the operating constraints are exceeded.
Most of the solar cell models suggested so far mainly employ steady state modeling methods to estimate the characteristic I V curve of a solar cell at a certain operating point.
A one-dimensional, steady-state model is developed from first principles in which the continuity, momentum, and energy equations of the liquid and vapour phases, together with the Young Laplace equation, are solved numerically to yield the heat and fluid flow characteristics of an inclined micro heat pipe which is operated optimally at a certain operating temperature.
To control a ship motion for certain operating conditions, a particular controller may yield a most suitable performance.
In the present study, ammonia was a factor with a strong impact and certain operating parameters (e.g. addition of TE) influenced the prevailing acetate concentration, possibly due to increased microbial activity or growth of a more proficient community.
Moreover, the estimated parameters of the model are only effective for a bounded neighborhood of certain operating point, and the computational burden will dramatically increase with the growth of model size.
If the design was flawed or was compromised during maintenance then the system can respond in an unexpected manner during certain operating modes.
However, reliability is associated with the ability to save the state machine fitness at a given time and under certain operating conditions (Mielczarek and Borkowski 2008).
