One of the contributing factors is the lack of Asbestos fireproofing above the 70th floors
But consider that asbestos is really toxic. The deaths directly attributable to the WTC attacks may not be over; we may be seeing a possibly large number of deaths by Asbestosis, a very nasty disease. Vilifying the EPA is pointless; asbestos is a separate issue.
The reality may be that a contributing factor is the lack of safe, effective, impact resistant fireproofing. Not the lack of Asbestos specifically.
Yes I think I've seen the same thing in the UK. The 'mechanical engineer' you talk of, broke my heart. He seemed to feel so personally responsible, something like 'survivor guilt'. I see him as somewhat hero-'ish'. He was a big part of wonderful expedition into the possible.
I hope that progress it not even slowed by this; I believe it will be accelerated.
Burning kerosene swims on water. No sprinkler system would have put out that fire.
True, however a sprinkler system would have reduced the temperatures reached inside the building, quite possibly enough to have saved more people. Also a sprinkler system would've reduced the number and intensity of secondary fires; office furniture and the like. Smaller buildings using 'feroconcrete' may well be safer, but this is irrelevant to the WTC terrorist attack, the towers weren't smaller or built using this concrete.
Working sprinklers would've made a difference. Your comment on halon is well received; probably halon would be more effective, assuming the delivery system was operating.
Overall I see this report as optimistic, better protected fire escapes, better fireproofing and more redundancy in the fire fighting capability may have saved, not only more people, but the buildings themselves. Applying the knowledge gained, will result in even studier building.
1: Microwave with thermal imaging camera, and a focusable beam, it would detect cold spots, and blast them. Also with a focusable beam, heating could start from deep within something like a chicken. The only draw back would be the incredible price.
2: Showers should have a peltier element to fine tune temperature, the thermo-static devices in most showers react to way to slowly.
..conditions? The effect in bright sunlight would be quite different to that of very low light conditions. Indeed in very low light conditions the eyes sensitivity may be significantly reduced. Even though red light preserves night vision best.
The only advantage this has over other HUDs, insofar as I can tell, is low power consumption.
Wake me up when it has red, green and blues lasers and cost $200.
If you are prepared to sit next to it managing it's input and output(ie tapes) it could anything up with out an overflow. A Turing machine doesn't need to hold an initial set, that's on the tape. It manipulates symbols on the tape to generate an output. A Sinclair could be programmed to do just that. A Sinclair could add 2 or 100, billion digit numbers. Not in memory of course; but by using tapes. I'm not sure that I'm getting that this across.
A Sinclair, or other computer is not defined by the data set, a Sinclair or even any current super computer could deal with any finite data set. The same thing is true for and Turing machine. What is this 'beginning data set' you talk of? I guess you'd expect a p4 to manage it? Well a p4 could also handle a billion, billion, billion, billion elements, or more it's just another Turing machine like the Sinclair. It'd just take a long time. I believe that you have utterly misunderstood the UTM.
Power is an interesting term, a Sinclair zx can carry out any task, that any computer so far created can carry out. It just takes longer. As a 'pure' model you are correct. But there are other aspects/interpretations of power.
You posted combined telescopes gives a effective mirror diameter of 430 meters, much bigger than any single mirror could be made.
From the article: This level of detail would require a single monolithic telescope mirror in excess of 50 meters in diameter.
and,
In the near future, NPOI will be commissioning all of the remaining stations onto which any of the six telescopes can be mounted for a maximum array size of 430 meters, the largest baseline of all current imaging interferometer projects.
..can get hold of course works and results from the degree web site. Timetables, locations, last minute changes for lectures are all available on line. Each area of the degree has a forum for students and lecturers to discuss issues, ask questions etc. All of this means she can hit the ground running, i.e. no need to wander around trying to find where something is being held. It's even more important to her because she has a social anxiety disorder.
I remember the frustration of trying to locate where and when events were being held, or turning up to something cancelled. It's early days but it's hard to believe that the internet(web, IM, email,??) will become increasingly interwoven with the fabric or everyday life, in way that makes it indispensable. IMHO it's fundamental importance will be closer to that of electricity than broadcast TV.
comments are often used to help describe overly complex tricks in software. The solution is not to comment but to simplify the code.
Iv'e often found examples where this is true, where the previous guy has taken an 'egotistical' approach to a problem. With the result that very few lines of code produce the result, but the solution demand commenting which was usualy lacking. Often actually writing some additional lines can be a better approach if it makes the code readable. IE self documenting.
Quite true, it could be using a very bright LED, and a mask that would be cheaper, initially I thought that a laser would solve any focus/perspective issues, but looking at this video Iv'e changed my mind. Putting the unit on flat surface cures that. Yep I think it may well be a mask, much simpler and cheaper. Add a couple of detectors and away you go.
..flicker at a frequency seemingly tuned to create horrible headaches. If this thing is real you couldn't use it for more than a few minutes, before having an epileptic fit. Increasing the refresh is not a simple thing, needing more than one laser/mirror combo. It's the mirror that draws the image, the laser remains still in most designs. Unless MEMS tech has vastly improved since last night, this seems to be an investor black hole.

Anonymous Cowards filtered. If their words aren't worth so much as a nom de plume why should I value them any more?
In this case I agree, often Anonymous Coward post can be interesting, but this was without any value.

Yet still they collapsed, yet still escape systems were unusable for a desperately unlucky few. And still the fire suppression system failed.
These were beautiful examples of engineering and architecture; no one could really have predicted the actual impact on them by what happened.
I applaud the construction workers, engineers and architects.
But to say lessons can't be learned is disingenuous.

Sorry I meant to ask; What.. like HOW? WHY?
..whatever, please provide a link? I can't spend the time looking into every claim I read on the web.
Regarding solar cell efficiency; you're right about them being inefficient.
takes more energy to produce a solar cell than the cell will ever gather in it's ENTIRE lifetime
Is this a fact? Could you give us a link?
..men in black, get to know what I'm eating. Cash transaction aren't enough.
I don't want them finding out the odd combinitions I get cravings for in the middle of the night.

..kinda sexy ain't it?
Hard drives, fans, cdplayers and the like, should be vertically or horizontally, in this mod the cdplayer and hdd don't seem to be.
The reason for this is; that this saves wear on the bearings. With fans it's not important but with more sensitive equipment it plays a role in MTBF.
wouldn't the sssca have made the enigma cracking group at Bletchley park criminals?
..you'r life is ruled by chemicals. Neurotansmiters. Knowing this might make you happier taking them.
..it's another step towards electronic documents getting the same validity as paper documents. We need this. Digital signatures would be nice too.
