The phrase "a small superimposed" is not complete and lacks context, but it is grammatically correct and can be used in written English.
It can be used when describing an object or element that is small and placed over another object or element in a layered manner.
Example: "The diagram featured a small superimposed image of the logo in the corner."
Alternatives: "a tiny overlay" or "a minor superimposition".
An alternating potential with a small amplitude superimposed on a constant potential was applied to one electrode.
Although this software captures everything on the screen, the speaker is typically not on the screen, or if they are, they appear as a head in a small box superimposed on a slide deck.
Moreover, we extend a prior solution for a small indentation superimposed on a finite equibiaxial extension by incorporating in this mixture model for the special case of an initially random distribution of constituents (actin, intermediate filaments, and microtubules).
This potential sequence of events motivates the consideration of a small indentation superimposed on a large "in-plane" deformation of a mixture that originally had a nearly uniform distribution of constituents.
Correspondingly, the low-dose region of the steady-state dose response curve may be monotonically increasing with a small slope, superimposed on the baseline, or nonmonotonic (i.e., slightly decreasing then increasing).
A few seconds later, though, the picture freezes and a small grid appears, superimposed over the baby's mouth.
The angular velocity is characterized as a small periodic perturbation superimposed on a constant velocity.
A simple plate model is used to represent the blade, and its angular speed is characterized as a small periodic perturbation superimposed on a constant speed.
The object of this research is to calculate natural frequencies and mode shapes of a small oscillation vibration, superimposed on large static displacement, by using the finite element method in conjunction with the equivalent uniform stiffness and mass method.
The spin rate of the beam is characterized as a small periodic perturbation superimposed on a constant speed, and the axial force is assumed as the sum of a static force and a weakly stationary random process with a zero mean.
