The phrase "presents a difference" is grammatically correct and commonly used in written English.
It is typically used to indicate that there is a contrast or discrepancy between two things. Example: The data from the experiment presents a significant difference in the reaction times of the two groups.
We have tested the efficiency using the parameters shown in Table8; however, the efficiency results did not present a difference with different coding rate and modulation scheme, so we show the results for Rc = 1/2 and for QPSK modulation scheme.
That, in turn, means you must present a difference.
The first third presented a difference, but it was not significant.
Ashyralyev and Agirseven [30] presented a difference scheme for the delay parabolic differential equation and studied the convergence of this scheme.
Eventually, by presenting a difference information assimilation method based on EnKF we successfully extract useful information from soil moisture data containing systematic measurement errors.
For the research of the parallel difference method for solving the nonlinear Leland equation, Wu et al. presented a difference method with intrinsic parallelism-the ASC-N parallel difference scheme [16].
Nascimento et al. ([2012b]) propose an experimental setup to investigate, from clients' viewpoint and by means of statistical tests, whether variant services present a difference in their outputs and their failure behaviours.
Solutions of LiOH and CaO/Ca(OH 2 initially present a difference in the rate of hydrogen generation, but they demonstrate a similar behavior after the consecutive addition of Al batches.
For the isotopic concentrations: 241Pu, 242Pu, and 242mAm, the results of all the institutions present a difference that increases at higher burnup; for the case of 237Np, the results of FZK diverges from the other results as the burnup increases.
