The phrase "a long time duration" is correct and usable in written English.
It can be used when referring to an extended period of time in various contexts, such as discussions about events, experiences, or processes.
Example: "The project took a long time duration to complete, far exceeding our initial estimates."
Alternatives: "an extended period" or "a lengthy duration".
The result of some of these schemes are so inaccurate that it becomes clear that they are not suited for time integration over a long time duration.
Then, an engineering example is provided illustrating the proposed approach and demonstrating the capabilities of the methodology for a large-scale simulation purpose that is characterized by a large number of discrete points of the roof and a long time duration.
The design ensures the stability of the gain and of the base line for events made of several pulses over a long time duration (up to 20 μs) and a total charge ranging from a few to 6×105 photoelectrons (typical value: a few thousands) with a peak photocathode current of up to 200 nA.
A long time duration exists between the generation of the two transgenic mice models and our study.
Adaptation to locomotion in water was essential for foraging by cetaceans, as they need to dive to great depths and for a long time duration predation.
Example questions: 'Menorrhagia is a serious condition' (consequences); 'Norethisterone will be effective in curing menorrhagia' (cure/control); 'Low back pain will last a long time' (duration); 'I feel like a failure' (state anxiety).
In addition to these crucial parameters, long-term produced water production is of paramount importance, in respect of the way, those wells that produce vast quantity of produced water for long time duration periods will be urgently needed a disposal or reuse management selection in the nearest areas to the field to retain the economic viability of the operation.
The estimator performs energy integrations successively with long time duration comparable to the delay spread of propagation channel.
It was found that the directivity patterns of non-compressed fields exhibited shapes similar to the patterns characteristic for sinusoidal excitation having relatively long time duration.
The force identification can be mathematically viewed as the mapping from the observed responses to external forces through a matrix filled with system Markov parameters, which makes it difficult or even impossible for long time duration.
The wear particle quantity analysis showed that the jewel-pivot bearing in oil lubrication could be used for long time duration in the vertical support system of small, high speed rotating machinery.
