The phrase "and accurate approximation for" is correct and usable in written English.
It can be used when discussing a close estimate or representation of a value or concept in a specific context.
Example: "The model provides an accurate approximation for the expected outcomes based on the given parameters."
Alternatives: "a precise estimate of" or "a reliable representation of".
Based on the characteristics of magnetically induced electric fields and the modified cable equation that we developed previously, quasipotentials are derived as a simple and accurate approximation for coupling of the electric fields to neurons.
In Pape and Vingron (2008), we propose a fast and accurate approximation for the significance calculation of CRMs circumventing the position independence assumption, incorporating similarity between PFMs, and incorporating the complementary strand.
It can be deduced that the time transformation approach offers simple and accurate approximations for the oscillators considered.
We have obtained closed-form expressions for the pairs DDE-SD, DDE-PD, PDE-SD, and PDE-PD and accurate approximations for CDE-SD and CDE-PD.
As the exact BER analyses for the considered scenarios are extremely hard - if they are not impossible, we propose some general and accurate approximation approaches for reaching our objectives.
In addition, a simple and comparably accurate approximation for the derivatives of the solution is also presented.
By using an accurate modeling approximation, we succeed in deriving a tractable and very accurate approximation for the EGP.
They concluded that the resulting distribution consists of weighted sum of the three independent components the static, the pause, and the mobility and also derived an exact formula of the asymptotically stationary distribution for movement on a line segment and an accurate approximation for a square area.
Finally, the method is illustrated by solving the problem in L-shaped polygon, and a high accurate approximation for the stress intensity factor is given.
Also the solution in various limits is analysed to recover firstly the solution for homogeneous dielectric particles, secondly to produce an exact solution for conducting media and thirdly to determine an accurate approximation for conducting spheres with very thin coatings, and which provides the opportunity to make use of existing conducting media theory.
The numerical results show that the least-squares mixed GMsFEM can give accurate approximation for both pressure and velocity using only a few basis functions per coarse element.
