The phrase "a direct formulation of" is correct and usable in written English.
It can be used when discussing a clear and straightforward expression or statement of an idea or concept.
Example: "The report provides a direct formulation of the company's goals for the upcoming year."
Alternatives: "a clear expression of" or "a straightforward statement of".
A direct formulation of the flow-average throughput and a comparison between both variants can be found in [21].
I am calling the view 'deflationary nominalism' given that it demands very minimal commitments to make sense of mathematics (Azzouni 2004), it advances a deflationary view of truth (Azzouni 2004, 2006), and advocates a direct formulation of mathematical theories, without requiring that they be reconstructed or rewritten (Azzouni 1994, 2004).
With round-robin scheduling, a direct formulation of the mean transfer time was found in [5, 24], since in that case the data rates of the users only depend on the number of users and their position, but are otherwise independent of each other.
The main idea is to incorporate Peskin's regularized delta function approach [Acta Numerica 11 (2002) 1] into a direct formulation of the fluid solid interaction force in order to allow for a smooth transfer between Eulerian and Lagrangian representations while at the same time avoiding strong restrictions of the time step.
Because it is difficult to give a direct formulation of this problem, the problem of simultaneous control of attractors is defined with θ, which is a threshold of the minimum score, as follows.
Two versions of the schemes are proposed: Scheme I is a direct formulation based on the micro macro decomposition of the BGK equation, while Scheme II, motivated by the asymptotic analysis for the continuous problem, utilizes certain properties of the projection operator.
The direct formulation of the complex variables boundary element method is generalized to allow for solving problems with constant body forces.
We present the direct formulation of the two-dimensional boundary element method (BEM) for time-harmonic dynamic problems in solids of general anisotropy.
In the direct formulation of boundary integral equation (BIE), thermal effect is present as extra integral, destroying the advantage of boundary modeling feature.
In this paper, the authors demonstrate that the direct formulation of discrete sensitivity analysis and the CTSE method solve the same iterative sensitivity equation, which sheds light on the most efficient use of the CTSE method.
We will derive the fundamental generalized displacement solution, using the Radon transform, and present the direct formulation of the time-harmonic boundary element method (BEM) for the two-dimensional general piezoelectric solids.
