The phrase "a fixed duration of time" is correct and usable in written English.
It can be used when referring to a specific, unchanging length of time allocated for an event or activity.
Example: "The project will be completed within a fixed duration of time to ensure timely delivery."
Alternatives: "a set period of time" or "a predetermined length of time".
The flux was incrementally increased for a fixed duration of time (15 min) for each increment.
For elevated voltages, the velocity due to EOF increased, leading to an increase in total heat transfer for a fixed duration of time; however, the joule heating also got elevated with increase in voltage.
The gel packs designed for heat therapy called "hot packs" usually consist of a silicate gel called Bentonite and are placed directly into contact with the area to be treated for a fixed duration of time.
iFor Wynkel 2004 [ 37], patients were randomly assigned to receive three treatments each over 24 hours in one of the following orders: CVVHD/CVVHpre/CVVHpost, CVVHpre/CVVHpost/CVVHD, or CVVHpost/CVVHD/CVVHpre. jFor parallel group trials; and for crossover trials that specified duration of RRT based on filter failure and not a fixed duration of time.
3D gradient-echo sequences allow for a shorter TE than spin-echo or fast spin-echo sequences, allowing for faster data acquisition compared to fast spin-echo sequences, and therefore allow more data averaging within a fixed duration of scan time [38].
For analytical simplification, we assume in this paper the input is periodical switching with the fixed duration of time.
Dynamics of the network are run in trials with a fixed duration of 2000 ms in simulated time.
As single sessions have a fixed duration of 20 minutes, the recommended minimal total time of use was 800 minutes in subjects renting the device for 40 days.
The time slots have a fixed duration of T s (dimension: [s]).
This phase was defined as the time before and after a dive bout, and had a fixed duration of 30 min, and could thus contain not only flight, but also time spent on land and on the sea surface.
Each experimental trial was assigned to one of these conditions, and the corresponding events were modeled with a fixed duration of 6 s (i.e., the duration of the visual presentation), time-locked to the stimulus onset.
