The phrase "approximated only by" is correct and usable in written English.
It can be used when discussing something that is nearly equal to or similar to another thing, often in a comparative context.
Example: "The beauty of the sunset was approximated only by the breathtaking views from the mountaintop."
Alternatives: "matched only by" or "equaled only by".
It is shown that extremely high-order RC interconnects can be accurately approximated only by a tenth or higher order ELO model.
Hypothetically, in these cases, the vaginal wall epithelium remains approximated only by the suture.
When the actual seawater density is approximated only by its mean value, relative inaccuracies up to about 2% were estimated in computed values of the bathymetric stripping corrections (Tenzer et al., 2011).
These ideal conditions are hard to achieve and are usually approximated only by studies in military cohorts.
The corrected quadrature formulae are quadrature formulae where the integral is approximated not only by the values of the integrand in certain points but also by the values of its first derivative in the end points of the interval.
ATP can buffer calcium as well as magnesium; but using a reduced reaction this can be approximated by only modeling the calcium binding, as changes in total free Mg concentration are small [ 36].
This can aid to find out the dominating mechanism on solute transport, and therefore the performance of breakthrough curve can be approximated by only one function in some specific cases.
It postulates that sparse or compressible signals, i.e., the signals that can be represented or well approximated by only a few non-zero coefficients in some domain, can be sampled and recovered from fewer number of measurements than traditionally required.
This lower bound has been commonly used in other domains, such as reliability analysis and referred to as Li-Silvester bound [17], where the tiresome calculation of an expected value over a large state space is approximated by only using the dominant terms in the summation.
It is reasonable that we cannot expect the calculated BER and the Monte Carlo simulated BER to be the same, simply because the calculated BER is only approximated first by using MGF matching technique then by using Gauss-Hermite polynomial approximation.
