The phrase "additional approximation" is correct and usable in written English.
It can be used when referring to an extra or supplementary estimate or calculation in a mathematical or analytical context.
Example: "In our analysis, we found that the initial estimate was too low, so we provided an additional approximation to better reflect the actual costs."
Alternatives: "further estimate" or "supplementary calculation".
Such bounds have utility both for robust control law design and for self-organizing approximators that could adjust the number of basis elements N by adding additional approximation resources in the regions where the approximation error bound is large.
However, the additional approximation error will be introduced if the channel time variations is severe.
Additional approximation possibilities have also been investigated with an emphasis put on the use of the Galerkin method based on weighted residuals.
This practice implicitly makes the additional approximation that the actual velocity and scalar (temperature or species concentrations) profiles within the channels are little affected by nonzero wall flow.
The adiabatic equation of ideal gases with temperature dependent heat capacity is strictly deduced without using the additional approximation condition in the relevant literature and is used to analyze the performance of the Diesel heat engine.
Once the detail function is obtained we look for spikes on it, if no spikes are present one can refine the analysis by performing the next decomposition level (i.e. decomposing the first level detail function into additional approximation and detail functions, and so on).
These estimates differ by more than those for ⟨ν⟩∞, perhaps because additional approximations have gone into the derivation of the relevant equations (in addition, we have made no attempt to carry out the rather complex propagation of the sampling errors of Table 2).
Note that (9) cannot be further simplified without additional approximations.
Once the penalty functions are designed, no additional approximations are introduced by the proposed formulation.
Additional approximations have been suggested, particularly for the computation of the interaction coefficients, using closed form expressions.
Cutpoint shift can be calculated accurately for rectangular nozzle but for round nozzle additional approximations are needed.
