How cane we calculate the dynamic viscosity of humidified gases at a given temperature theoretically? Data is not available for fitting.
Is it possible to have a matrix A which is invertible, and has repeated eigenvalues at, say, 1 and still has linearly independent eigenvectors corresponding to the repeated values? I require any...

Consider a time series (stationary or non-stationary). I fit a linear model of order 0, i.e., an intercept to the data. In the stationary case, this corresponds to the mean. Now, when I calculate...

I have a state space model - linear or non-linear. I know that there is (are) wrong parameter(s) in the model (the model structure is correct though). Is there a method to isolate the wrong...

Some sources say it is treated as Newtonian as ethylene glycol has a higher viscosity than water, which affects the flow characteristics in simulations. But some also say it is non-Newtonian.
