The phrase "a closed form approach" is correct and usable in written English.
It can be used in contexts related to mathematics, statistics, or problem-solving where a specific method or solution is presented in a definitive and explicit manner.
Example: "In our analysis, we adopted a closed form approach to derive the solution efficiently."
Alternatives: "a definitive method" or "an explicit solution".
Frequency tunable comb resonators have been successfully designed and demonstrated based on a closed-form approach of a curved comb finger contour.
While only flexural deformations were considered in the original paper, this paper presents a closed-form approach that has been modified to include shear deformations.
In this paper, a closed-form approach is introduced to determine, exactly, both the torsional constant and all shear flows for multi-cell cross-sections under torsion; no simultaneous equations are required and there is no need to distribute shear flows back and forth between cells.
A closed form substructure approach for circular geometries is obtained by employing the method of wave functions expansion and the image technique.
The simulations show that good estimations of vapor descriptors can be obtained by using a closed form estimation approach that is similar to the closed form solution for purely mass-transducing sensor arrays.
Our choice of survival distribution was limited as distributions such as the Log-Logistic or the Log-Normal do not allow the probability of healing over time to be expressed in a closed form, and hence impede the approach proposed here for the joint synthesis of IPD and AD.
In [16], even though the proposed approach has a closed form for a diagonal matrix denoted by Φ, the final relay precoding matrix should be chosen in order to be a block diagonal matrix with minimum norm.
The first approach employs a closed form analytical solution for critical velocity that is based on the Bernoulli Euler model of a beam resting on an elastic foundation and subjected to a moving load.
These approaches lack a closed form solution, which is a drawback since a hydrodynamic model in closed form is advantageous for control design and analysis.
In fact the ideal QAM SER for an OFDM system over a Rayleigh fading channel can readily be derived in a closed form by using the moment generating function approach given in [9].
