<p>It was the “truck and company” that was cleared to cross.  That’s probably 5+ vehicles you can see following the lead truck that were all approved. All while the jet was on short final.  That controller lost situational awareness due to task saturation as a result of emergency aircraft on taxiway parallel to runway 13.</p>

<p>I worked on a very capable unix based CASE system for Athena Systems in 88 & 89. There's still some articles about it online like here <a href="https://www.worldradiohistory.com/Archive-Electronics/80s/88/Electronics-1988-11.pdf" rel="nofollow">https://www.worldradiohistory.com/Archive-Electronics/80s/88...</a> (complete with screen shots) on page 37. What I recall being the uphill battle was fighting the peace dividend granted by the cold war ending. Defense contractors, our primary market, we’re in cost cutting mode for a decade.</p>

<p>If you want to get better at mathematical modelling in general I recommend a traditional text book dedicated to modeling, like the 11th edition of "Introduction to Operations Research" by Hillier and Lieberman.<p>As for the "mathematical equations" referred to by a parent, we're talking linear algebraic equations with perhaps a 2nd order term thrown in for quadratic models.  I think these should be within the grasp of someone who wants to delve into the topic, and if not perhaps it's a good place to start dig deeper.<p>edited to be less of a prick.</p>

<p>In engineering text books, sure they use radians.  In mechanical engineering design if you put a radian on a geometrical dimensioning and tolerance sheet it's not going to go well for you.<p>I suspect the same holds for civil engineering too.  I have my doubts that radians are useful in chemical engineering, but I could be wrong there.</p>

Joe had the unique ability to teach very technical topics with a special brand of humor.<p>Knowing CLIPs got me my first job in Silicon Valley / Los Altos in '88.  Thanks Gary!</p>

<p>90% or higher?  No way, there’s not a credible large scale survey that makes that claim.  Closer to 15-25% suffer from incontinence permanently.  And 30-50% will have ED. And 100% of outcomes will loose inches.<p>50% of RALP patients will have biochemical reoccurrence within 8 years.  It takes 15 years of low PSA (<.1ng/ml) to state you are cured.<p>The goal is to die with PaC, not because of it.<p>All of these stats are available at PCRI.</p>

<p>I understand and agree.  I was Gleason 7: 4+3 intermediate aggressive.   Caught it very early, no spread, so RALP was performed 5 months ago.  Now I’m deep in the throws of  pelvic floor PT hoping to gain some semblance of control again.<p>Hopefully your surgeon has performed (unlike mine) more than 1000 RALPs - the incontinence outcomes improve greatly when their experience is that high.<p>Best of luck to you.  DM me at gmail if you need/want to talk about your upcoming RALP.</p>
