System-specific information, like reaction rate constants and sensitivities, are encoded as constant parameters.

The constant parameters are such that .

In many practical signal processing problems, the objective is to estimate from measurements a set of constant parameters upon which the received signals depend.

Right, so you need to know that our model is characterized by constant parameters over the sample.

Right, I'm going to go through methods of how we can detect structural change by the non constant parameters.

Although the analysis was done for red oak, the procedure may be applied to any species of wood by adjusting the constant parameters of the model.

However, the input signals must be extremely small for the first of these two equations to apply with constant parameters.

We use the convention that any constant parameter in a model is included when counting the parameters.

Therefore, care has to be taken in order to keep constant these parameters for all measurements.

It is possible to define independent variables, dependent functions, scalars and constant parameters:
