The phrase "a direct derivation" is correct and usable in written English.
It can be used when discussing something that is obtained directly from a source or origin, often in academic or technical contexts.
Example: "The term 'biodegradable' is a direct derivation from the combination of 'bio' and 'degradable', indicating materials that can be broken down by biological processes."
Alternatives: "a straightforward derivation" or "an immediate derivation".
The SDL specification allows a direct derivation of object interface description in Interface Definition Language (IDL).
The central result is a direct derivation of the Vogel-Fulcher/Williams-Landel-Ferry formula.
With individual participant data an analytic standardisation across the studies and a direct derivation of the information requested is possible, independent of significance or how it was reported.
Secondly, central aortic pulse pressure is used as a measure of central aortic stiffness instead of central augmentation index, as it is a direct derivation from the difference between central aortic systolic and diastolic pressures, without the assumptions of a generalized transfer function as applied to the central aortic augmentation index.
The structure and symmetries of the atom, including Bohr's postulates, become intuitively apparent at stage three, called System 3. A transparent Quantum Relativity emerges naturally with a new direct derivation of the Lorentz transformations.
In Section 2, we provide a new, direct derivation of the result that establishes the scattered field as the Fourier transform of the RBC scattering potential.
This paper presents a new and direct derivation of the well-known stationarity properties of Rayleigh's Quotient (Lagrange's Theorem).
The direct derivation of IFR is the second derivative of signal phase which can be expressed as: IFR t triangleq frac{1}{2pi}frac{d^2phi (t)}{d{t}^2} (8).
A more thorough examination of the state of X inactivation will require the direct derivation of naive ESCs from female human blastocysts (the ESC lines derived in this study were all male).
Though greatly simplified from a physiological neural network, the model is chosen as it is analytically tractable and thus enables direct derivation of the parameters such that there is a critical regime.
Our approach for the traffic congestion detection in sequences of optical images is based on the modeling of a traffic flow on the road segments and thus allows the direct derivation of the required traffic parameters from the data.
