The phrase "a certain regularity" is correct and usable in written English.
It can be used to describe a pattern or consistency that is not precisely defined but is noticeable in some context.
Example: "In the data collected, there was a certain regularity in the occurrence of the events that suggested a possible trend."
Alternatives: "a specific consistency" or "a particular pattern".
Although the random path also has a certain regularity, which is slighter than the raster and circle path, so the regular ripple will be suppressed, that is, the PSDc consistent with the path spacing is suppressed.
Differences of content are obscured by a certain regularity of style.
I used to end up lost in the wilderness with a certain regularity, but it's been years since that happened.
With a certain regularity, New Yorkers are given the opportunity to engage in a satisfyingly maddening if futile pastime: decrying the obscenities of rent regulation.
The question has an affirmative answer for a class of circuits that fulfills a certain regularity condition.
It has been proved that under a certain regularity condition, B q improves the smoothness of a function which does not satisfy the Hölder condition.
Now we start our discussion by recalling the fact that solving (6) with a closed form solution is impossible, thus we shall adopt some useful way to find the evidence that a solution with certain regularity exists.
Next, we specify a class of functions with certain regularity properties and using a compactness argument establish the convergence of smooth solutions to the solution of the original problem with piecewise constant initial density (rho_{0}).
We need to check the reasonableness of the boundary value problem (2.10)–(2.13) under the definition of weak solutions, that is, the solution in the classical sense are necessarily the solutions in weak sense, and conversely when a weak solution satisfies certain regularity conditions, it will surely satisfy the given boundary value conditions.
In this multi-dimensional extension the half-line is replaced by an open set Ω⊂Rn, n∈N, n⩾2, where Ω has a compact, nonempty boundary ∂Ω satisfying certain regularity conditions.
Here, A : Ω ¯ × R N → R N is a map which is strictly monotone in the second variable and satisfies certain regularity conditions (see the following assumption (A)).
