The phrase "a unified approximation for" is correct and usable in written English.
It can be used in contexts where you are discussing a singular method or model that provides an estimate or representation of something.
Example: "The researchers developed a unified approximation for the complex system, allowing for easier analysis and understanding."
Alternatives: "a consolidated estimate for" or "a singular model for".
Through using perturbation methods for low amplitude oscillations and numerical integration for large amplitude vibrations we establish a unified approximation method for linear, softly nonlinear, and bi-stable nonlinear energy harvesters.
Moreover, the code is designed to give a unified approximation order throughout the given domain.
In this paper, we develop a unified framework for approximation of the performance of general telecommunication networks based on a decomposition strategy.
In this context, using tools from information and queueing theories, mathematical convex programming, and stochastic approximation, a unified framework for channel- and queue-aware QoS-guaranteed cross-layer scheduling and resource allocation algorithms has been developed in this article.
A unified approach for accurate approximations of displacements and displacement derivatives with respect to design variables is presented.
In general, there is not a single optimal solution to a multi-objective optimization problem, however, using tools from information theory, queueing theory, convex optimization, and stochastic approximation [24], a unified framework for channel- and queue-aware QoS guaranteed scheduling and resource allocation for heterogeneous multiservice OFDMA wireless networks is proposed in this article.
Here, using the full power of subset systems, we provide a unified approach for proving simply the approximation ratios of a greedy algorithm for these four problems.
It is shown that the present first-order approximation of the effective thermal conductivity of the composite can be written in a unified formula for different microstructural characteristics and possesses a good engineering accuracy.
The present solution provides a unified first-order approximation formula of the effective thermal conductivity for different interfacial characteristics and fiber distributions.
