The phrase "sole parameter" is correct and usable in written English.
You can use it when discussing a single variable or condition that is being used to measure or judge something. For example, "The sole parameter by which we gauge success is profitability."
It is particularly suited for conceptual and preliminary design since it relies on the operating empty weight as sole parameter.
A single class of utility function with risk-aversion as sole parameter emerges when risk-aversion is regarded as a function of the present wealth, rather than subject to alteration through imagining possible future wealths.
The results demonstrated that the lipophilicity of the tested compounds was not the sole parameter affecting antimycobacterial activity, as well as the potential and importance of developing new fluoroquinolone derivatives against mycobacterial infections.
The propagating crack length is considered as the sole parameter to evaluate safe fatigue life, including the use of an "equivalent crack propagation rate", which averages the intense variations of CPR in the vicinity of grain boundaries.
For the liver, the SUVaverage was the sole parameter that did not vary over time.
Finally, note that after neglecting SFO the sole parameter remaining in (17), (18), (19), and (20) is the intercarrier spacing.
Investigations of multisegmental foot motion may reveal additional information about the contour effects; analysis of contour variations may also be warranted to investigate the possibility of controlling motion based on rocker sole parameters.
The combination of this model with the relationship between longitudinal and radial dispersion leads to the definition of the sole hydrodynamic parameter λO (one-parameter hydrodynamic model).
The sole free parameter of the gradient model, the influence parameter \ \kappa\), that characterizes the influence of concentration gradients on the interfacial excess energy, is determined from our measurements.
For PorGA, water turbidity and depth (the sole physical parameter) were superior to any of the biotic parameters in predicting the prevalence of the disease, with prevalence peaking in shallow, less turbid waters.
Kurtosis was the sole densitometric parameter entered, because it correlated strongly with other parameters (|rs| = 0.85-0.98), anotherther study in IPF recognized its superiority in predicting mortality [ 5].
