"operational duration" is a correct and usable phrase in written English.
Generally, it is used to refer to the length of time during which a type of operation is effective or running. For example, "The operational duration of the machine is three weeks."
But this operational duration was only calculated from the aspect of cost benefits with economics' perspectives.
With increasing operational duration (t > t 0), the aggregates are progressively coated with iron oxides (in situ coating).
It is suited for predicting the thermal changes in the subsurface for an operational duration of 30 years.
This thermal influence will shorten the operational duration of the tower foundation, especially in condition of climate warming.
This paper provides the results of a cost optimization for a CANDU spent fuel canister as well as the operational duration of an HLW repository.
Temperature had the most significant effect (RS Mp < .05) on cellulose content of residual biomass and reducing operational duration of < 0.5 h may be viable according to RSM.
The simulation describes the real BTES in an accurate manner and is suited for predicting the thermal changes in the subsurface for long-term operational durations.
This study uses a laboratory scale column set-up to explore how Escherichia coli (the chosen indicator organism) removal in the stormwater biofilters is impacted by: plant presence and species type, the presence of a submerged zone (SZ), and operational conditions (duration of dry periods and changes over the initial stages of the system's life-span).
Also the investigators used some operational definitions; Duration of illness was measured from onset of symptoms till last follow up in months.
A generalized additive model (GAM) was used to analyze sinking depth and sinking speed under different sea conditions (current speed and direction at different layers), gear design (length-height ratio, towing line length and purse line length), and operational methods (shooting duration and setting speed).
A dimensional analysis was subsequently carried out to optimize adsorption performance for any desired operating condition, which is determined by the choice of adsorbent vapor pair, adsorption duration, operational pressure, intercrystalline porosity, adsorbent crystal size, and intracrystalline vapor diffusivity.
