Power factor would be improved, especially in office environments where every cubicle would have one well designed AC/DC converter instead of 5 cheap ones.
This is probably the biggest win from your proposal - the drop in current draw on the AC lines from improved power factor should cut power losses. Similarly, it would be cost-effective to make the PSU maintain efficiency at low loads.
Not sure if 12 or 48V would be the best pick - maybe split the difference and go for 28V. 48V is pushing the limit for low RDSon FET's in addition to f*0.5*Coss*V**2 rearing its ugly head at higher voltages.
Hmmm. There is a standard for 12V DC that's a bit better than the crappy cig lighter sockets - the Molex connector used for hard drives (which would be a lot more compact than the cig lighter sockets).
Increasing the input range to 48V and adding the power negotiation would definitely add cost to these applications.
If Power over Ethernet really takes off, then I would suspect that there would be a big market for devices on the load side - which would drive the cost down.
You don't have to be a US company to take US money.
Yes and no. IIRC, gambling debts are not enforceable across state lines - so someone can simply walk away from a credit card transaction (may not be that simple).
Contrary to what the article says, a complete ban on online gambling would not violate the WTO agreements, any more than France's prohibition of Nazi merchandise be a violation of WTO regs.
It seems to me that this would be NAGT (Not A Good Thing), particularly if you have a bad guy, who knowing that this generator would be used, would decide to ship a piece of U-235 just barely subcritical. There may not be much of an explosion, but it would be very dirty.
There wouldn't be an explosion.
And how would this work at detecting PU-239?
Same way as detecting U-235. Shoot neutrons of any energy into Pu-239 and you will get fissions.
a neutron generator is an excellent method for detecting fissionable material
True, but what is of more concern is fissile material. U-238 is fissionable (need at least 600keV neutrons) - U-235 is fissile. To be completely fair, neutron generators are useful for detecting fissile material.
and I'm sure the folks over at Homeland Security would like a better way to guard against nuclear devices being smuggled into our country.
DHS is working with several organizations to address that problem.
Does Verizon believe that they're not charging their customers enough for the services the customer uses?
The logical conclusion is that they are doing a bait and switch - attracting customers with an underpriced access plan and then hiking the price of getting full access.
Again, the telecoms see these content-services as helping to pay for this bandwidth build-out.
That's pretty much what Compuserve was doing before the internet boom - they were charging access by the minute, had different rates for 300 baud, 2400 baud and 9600 baud, access to the Forums was extra (and revenues split between the forum operators and CIS).
I suspect one reason that they're so hell bent on rolling out FIOS is that they can shut out other ISP's and thus access to other VOIP providers - not to mention Google Video.
If the Radiation sensors have good enough energy resolution, then it is a piece of cake to say that the gamma's are coming from Tc-99m and not something more sinister. Tc-99m has a radiological half-life of 6 hours and a biological half-life of 1 day. Another way to prove that the radiation is from a stress test is that the radiation is most intense over the heart for a few hours afterwards and then becomes most intense over the liver. The dose rate in first few hours after the test is pretty high - I was seeing 9mREM/hr about three hours after my last stress test - I'm also a bit surprised that little was said about dosing others, however the NRC regs say that patients can be discharged without instructions provided that the max possible dose to others is less than 100mREM.
My cardiologist stated that several of his patients have been questioned after traveling down to TJ - Customs has radiation portals at every lane on the San Ysidro border crossing. There was an incident a couple of years back where a nuclear medicine patient tripped a rad alarm on a garbage truck in Escondido.
In terms of "scientific tools", I don't remember seeing any serious Fortran compilers until the IBM PC became available and ditto for Pascal.
My recollection was that MS was selling Fortran for CP/M in 1979 and there were hooks to make use of the AMD 9511/9512 numeric processors. Some of the oddities of the L80 linker were due from the support for Fortran-80. Development on F80 stopped in 1982.
The UCSD P-system had both a Pascal and Fortran compiler - though run-time speed was slow. DR had Pascal MT+ - also available with speed programming package (first edition IDE).
FWIW, the first MS Fortran compiler (v2.02, first avialable 4 to 5 months after the PC) for the IBM PC was a POS - the first really decent one was v3.10 which came out late 1983. The Pascal compilers were a bit better - MS was doing a lot of development in Pascal - usually cross-compiled from a VAX. The first MS C compiler was a repackaged Lattice compiler.
Sounds like the OP was reacting to comments re:"Their pipe" - stating that while Verizon/SBC -er- ATT/BellSouth/Comcast/etc may have paid for the fiber/cable they certainly haven't paid fair market value for the Right-of-Way.
The OP sort of hints at another point, the Congress and FCC have usurped the local governments authority to regulate the "broad-bandco's" (for lack of a better word) to ensure that the companies were meeting the needs of the local community. Now the fun part is that the authority to fine someone going wild with a backhoe rests with the local or state governments - maybe if we get enough cases where fibers/cables were cut with backhoes and nobody being fined, then the Congress/FCC may give back some of the authority to the local governments - which includes demanding a cut of the revenues for broadband service for use of public right-of-ways (i.e. streets).
To make this even more fun - I do own Verizon stock (was GTE before the merger).
FWIW, in a couple of weeks, it will be illegal to dispose of batteries in a landfill - they must be turned into a proper waste disposal or recycling facility.
A Mis-light of an SRB on the pad (prior to launch) - Apparently NASA takes huge precautions with their SRBs due to volatility of the solid fuel.
Volatile? While the fuel is a bit more volatile than tire rubber, it isn't a great deal more so. The fuel itself resembles a soft rubber. The one issue is that once the fuel ignites, it doesn't stop burning until all of the fuel is consumed.
OTOH, jst before the first flight of Columbia, NASA and Rockwell engineers discovered a trick circuit that could lead to simultaneous SRB ignition and separation. THAT would ae left one hell of a mess on the area around the launch pad.
I was laughing so hard the first time I saw the webpage that my 6 year old son came over to see what was so funny - passed along the URL to some co-workers as well as someone at LockMart and another at ATK Thiokol - all got a good chuckle.
As for your fighter problem, sea-water contamination of the composites used in the F/A-18 has been a problem and was resolved once people realized the long-standing issue with aramid (exposure to water degrades the fibers).
One project that I started working on in 1990 was trying to measure the moisture content of the F/A-18 composites - unfortunately it wasn't as successful as I would have liked. IIRC, there was some concern that the trapped water could boil from the heat induced by supersonic flight, which would then lead to delaminations.
I'm not angry at Rockwell, I'm angry at the Nasa adminstrators who assumed "foam" meant "harmless foam."
Reminds of Jon-Erik Hexum's death - he thought he was playing with a "harmless" blank round - the peice of wadding over the powder charge came out fast enough to inflict a fatal injury.
You may think it's nitpicking, but it often matters for people to understand exactly which part of something caused deaths or destruction.
I certainly don't think of it as nitpicking - one of the more enlightening things about reading the book "The Challenger Luanch Decision" was that what doomed the Challenger was not the initial leaking at SRB iginition, but the shaking of the SRB casings while flying through some high altitude wind shear, which then caused the seals to start leaking again.
Remember, the US is the ONLY country to have a track record of using nuclear weapons against civilian targets in war.
Ask the Chinese about how nicely the Japanese treated civilians in Nanking in 1938.
Ask the POW's who weren't executed by the Japanese how they were treated in captivity.
FWIW, the Japanese were preparing to use bubonic plague infested fleas in 1944 - fortunately for the Japanese the submarine carrying the fleas was sunk - had the Japanese used those fleas as intended the US would likely have retaliated with massive uses of chemical and biological weapons.
One more thing - was being the target of a nuke all that much worse than being a target of a fire-bombing raid (think Hamburg, Dresden, Tokyo...)??
You know, they *might* just have missed the call saying "Banzai! we're attacking!"
Actually the message was not missed - the US knew by the 4th of December that war with Japan was only a few days away - and orders were sent out for the destruction of decryption gear in the Philipines and Guam. What wasn't known was the exact time and place for the attacks.
There's a slight issue with timing here - from TFA, the intercepts begain before Pearl Harbor, but the US didn't declare war on Germany until December 11 and only after Germany declared war on the US. Had Hitler known that the Japanese had no intention of declaring war on the Soviet Union, he probably would not have declared war on the US and the majority of the people in the US had a strong aversion to getting into another war in Europe after the fiasco of WW1 (the US and the world would have been better off if the US stayed out - the "Spanish Influenza" may have stayed in western Kansas).
From Pearl Harbor to 1945 we were also in a declared state of war with the axis nations.
Except that, if your read TFA, the intercepts began before Pear Harbor. Also bear in mind that the UKUSA agreement covered countries other than the axis nations.
Your post has restored my faith in the Slashdot community...
Curious thing the Nazi genocide program - I've seen reports that up to 11 million were killed by the combination of death squads and death camps, but most reports focus on a subset of 6 million. The stupidity of the Nazi's was that had Hitler made an effort to ally with the Ukrainians instead of slaughtering them, the Soviet Union would likely have ceased to exist by the end of 1942.
On a related note, there was one loony who thought the stories about the Nazi death camps were works of fiction and wrote a letter to the Governor of California stating that he (the governor) would understand his position. That sad part was that no-one reported the irony of a "holocaust denier" trying to take his case to the son of a survivor of the Turkish genocide against the Armenians (the Governor being George Deukmejian).
Also curious that Japan gets little attention for their massacres - notably the "Rape of Nanking" - the work of "Unit 731" - and their treatment of POW's. And I just found out that they were planning to use bubonic plague infested fleas against the American forces taking the Mariannas (and re-taking Guam) - fortunately for the Japanese, the submarine carrying the infested fleas was sunk.
By nature, the any corporation's sole obligation is to increase profits for its stock holders.
Except that most corporations exist to limit the liability of the stock holders (otherwise ownership could be held by partners). In return for the the limit on the stockholders liability, the corportations do have a legal obligation to operate in the public interest, convenience or necessity. The SarbOx regulations are a start in reminding management (and maybe a few stockholders) of the responsibilities of being a corporation.
What may be the biggest incentive to have the likes of Microsoft, Yahoo, Google, etc. clean up their act is to limit the "limited liability" aspect of corporations - institutional investors will have a very different take on management if they become liable for the misdeeds of the corporations whose stock they hold.
The three phase electrifications (Italy, 1909 Cascade Tunnel electrification in the US) and phase converter electrifications (N&W, Virginian) had pretty much automatic regenerative braking - relying on the normal operation of an induction motor. The down side is that the systems operated at fixed speeds. Possibly the first major use of variable speed regeneration was the Milwaukee Road electrification of 1916 - analysis showed about a 17% reduction in energy consumption.

Not sure if 12 or 48V would be the best pick - maybe split the difference and go for 28V. 48V is pushing the limit for low RDSon FET's in addition to f*0.5*Coss*V**2 rearing its ugly head at higher voltages.
Hmmm. There is a standard for 12V DC that's a bit better than the crappy cig lighter sockets - the Molex connector used for hard drives (which would be a lot more compact than the cig lighter sockets).

U-238 + neutron -> U-239
U-239 beta decays -> Np-239
Np-239 beta decays -> Pu-239
Depends on what you mean by miniscule. Natural U production reactors convert ~0.3% and light water reactors convert 3-5%.
There wouldn't be an explosion.
And how would this work at detecting PU-239?
Same way as detecting U-235. Shoot neutrons of any energy into Pu-239 and you will get fissions.

I hate to break it to ya, but 5 tons of Plutonium was released into the atmosphere between 1945 and 1963 - so some of that is in your backyard.
Nuclear waste is still gonna be dangerous tens of thousands of years from now
After a few hundred years, the waste is about the same danger as the original ore.
