parameter

Forms

1.A value kept constant during an experiment, equation, calculation, or similar, but varied over other versions of the experiment, equation, calculation, etc.
- As molecular surface-to-surface contacts control both solution phenomena and surface phenomena, it is not surprising that various correlations of cohesion parameters and surface phenomena can be found.
2.A variable that describes a property or characteristic of some system (material, object, event, etc.) or some aspect thereof.
- To this end, we derive an a posteriori error estimator for the error with respect to the unknown parameter.
- Cohesion parameters (solubility parameters) can be used with full theoretical justification to characterize many surfaces ..
- The parameter estimation problem considered in this chapter consists of estimating the unknown parameter, ū [a barred v, actually], given N samples of the observation process.
3.An input variable of a function definition, that gets an actual value (argument) at execution time.
4.An actual value given to such a formal parameter.
