The phrase "average over the duration" is correct and usable in written English.
It can be used in contexts where you want to calculate an average value across a specified time period.
Example: "To get a clearer picture of the project's performance, we need to average over the duration of the last six months."
Alternatives: "calculate the average throughout the period" or "find the mean across the timeframe.".
Making an experiment measuring one of these quantities takes time and it is assumed that what measurement devices register is not the instantaneous value of the function in question, but rather its time average over the duration of the measurement.
Although levels of HCl and HF measured here did not exceed WHO guidelines, local populations are likely to be exposed to levels greater than those reported by this study as diffusion tubes provide an average over the duration of exposure, which will include variations in degassing and wind direction.
To compare lamellar activity in the cell front versus rear, the area of extension versus retraction was quantified in these regions of the cell and normalized to the average over the duration of the movie.
The fact that this distance is a time and ensemble average over the duration of the experiment and the ensemble of molecules present is an important consideration in the analysis of PRE data.
Although all summary measures provide an imperfect assessment of adherence, overall adherence, since it takes into account the total days that each participant is in the trial, may provide a reasonable reflection of drug exposure on average over the duration of the trial.
The strength of the air gun pulses can be measured in a variety of ways, but National Marine Fisheries Service NMFSS) commonly uses "root mean square" (in dB re 1µPa [rms]), which is the level of the received air gun pulses averaged over the duration of the pulse.
This measures the number of complete frames received per second, averaged over the duration of a measurement trial (the higher, the better).
In the rate model, the LNc spiking rate averaged over the duration of each stimulus presentation replaces the spike density function in the response matrix (see below).
In contrast, the manganese content in hair will reflect the metal uptake averaged over the duration of the follicle formation.
In order to estimate the exposure pedestrians may experience, the instantaneous sample concentrations of diesel particulate matter obtained at 5 Hz from the DMS500 were mathematically averaged over the duration of each drive by incident.
Hierarchical primary end points are: a comparison of home BP (home systolic blood pressure (HSBP)) averaged over the duration of phase 1 and 2 in the combination versus monotherapy arms.
