Relative velocity algorithms in tomographs.

[Gary Prentice]

I'm puzzled about the use of the relative velocity algorithm used in the PiCUS 3.

 

Because the system uses the highest velocity reading and calculates other readings between sensors in relation to that, what would happen with a less dense wood -like willow?

 

Where velocity is slow, if there was widespread decay in the cross section which wasn't advanced enough to significantly reduce the velocity in relation to this 'normal' reading, how well would the tomogram show it?

 

I've a feeling that the answers going to be that the interpretation would require a fair degree of experience by the user!

Mmmm.

Not very well presumably! I suppose they are only useful for locating distinct pockets of decay where the relative densities are different.

 

Your question also highlights the issue that you can't use a Picus to compare several trees, even of the same species.

I know what you mean. I barely understand the question and I wrote it:confused1:

I'm trying to form a conclusion which is better, the relative values of the PiCUS, the tree specific velocities (of normal trees) used in the Facopp/Arbosonic 3D or the conifer/ring/diffuse porous input of Rinntechs Arbotom.

Cool, let me know what you decide! I don't know anything about the second two!

I think it something to do with why it takes so long to get up in the morning !

Thats just age and knackered joints mate. But it's all good as long as you're getting up.

Was that " getting up " or " getting it up " !

You know how you develop a visual image of people, based on their posts? For some reason, my image of you has changed:lol:
