Deco for dummies - the book

[wedivebc]

I'd like to see a book that gave you enough background with a clear enough presentation to actually implement RGBM or VPM.

You need to read "Technical Diving in Depth" by Bruce Weinkie if you want that. I don't believe you can cover a topic as invloved as RGBM implementation in a "For Dummies" type book.

I've got that one and his RGBM book, and i still can't quite decipher how it works sufficiently to implement it...

You're a UNIX guy, have you looked at the C code for VPM http://www.decompression.org/maiken/VPM/Links.htm
Maybe a little reverse engineering will help your understanding.

I think that the mere fact that Lamont can't "use" Weinkie's work is a sure sign that the layman has no hope. Lamont is interested, intelligent, university educated and informed. The fact is, Bruce Weinkie's work is intended for the 50 people on the planet who have some idea where he is coming from.

Maybe 50 is an exaggeration.

I can't imagine how anyone could take something as complex as mathmatical modeling of a decompression algorithm and make it understandable by us "dummies" Like you said, if someone as interested intelligent and educated as lamont has trouble with it how are we ever going to understand it? Having said that I recall UWSojurner wrote a really good explaination of gradient factor on www.rebreatherwold.com that made complete sense to me.

It really CAN be done -- not deco at the PADI dive book level, but deco in English with a little math. Eric Baker has a couple of very readable papers; Marcin Kaluza has a readable paper on VPM. I really think such a book could be written, incorporating some physiology, some history, and some functional description of the algorithms and how they differ, and perhaps with some examples of dive planning using various pieces of software. I would find such a book fascinating and invaluable. And I majored in math.

I thought that was all Fortran.... I'll look again...

ugh, that looks very f2c'd which is painful C code...

I think you need the intersection of having years of exposure to advanced decompression theory, and years of exposure to computational physics to be able to digest BRWs books sufficiently to actually implement the algorithms. The problem is that just approaching it from a computers + math background the specification in those books glosses over details that are necessary to implement it, but which people with the deco and physiology background would probably just know...

now that i've got some better references on the oxygen window, i should see if i can slog through it and at least implement the dissolved phase part of the theory...

Id be interested in buying it!! Where do I order?
