Exactly. This is a remote visual inspection that maneuvers a tool to a difficult-to-access area and feeds images back to to a qualified inspector. The trick is ensuring the quality of the images, which should not be hard with adequate standards.
Similar systems are used for inspecting the insides of nuclear reactor vessels. Since the dose would kill any inspector that got inside the vessel, underwater cameras and/or miniature submersible robots are used. Before the inspection, they will hold a calibration standard with a variety of colors and scratch sizes in front of the camera to ensure that it can see the types of defects that being looked for. Before the camera is removed from the water, the standard is filmed once again to ensure that the camera quality did not degrade during the inspection. This is controlled by the ASME Boiler and Pressure Code, which we are bound to by regulations. A similar set of standards and quality assurance could be applied to camera inspections of aviation in order to reap the time/manpower benefits without reducing the ability to find dangerous defects.
Agreed. I'm studying nuclear engineering. While all the atomic level material was taught in N, J, and kg, the hydraulics courses about fluid flow are being taught in English units. The professor pointed out that these units are used in every US nuclear plant, so it would be more practical to learn in these units. There are some hybrid units though, such as watts per foot (for fuel rods).
Engineers, statisticians, and accountants are hired more for their way of thinking than for number crunching.
The engineer asks "How does it work?"
The statistician asks "How often does it happen?"
The accountant asks "How much will it cost?"
The computer asks "Cancel or Allow?"
Naval reactors run fuel that approaches weapons grade enrichment (~90%). This means that they have to refuel about every 20 years, compared to ~3 years for a civilian reactor with 4% enrichment. However, naval reactors are guarded by military personnel and in the case of submarines, are hidden. Civilian nuclear reactors do not have this luxury. There is the perfectly viable, save for political reasons, option of taking weapons grade fissionable material and blending it with depleted uranium to make fuel suitable for civilian reactors. The problem is that most weapons use plutonium, which is less desirable in reactors because it causes more rapid power changes and in general changes the handling characteristics that operators may be used to, as most civilian reactors use uranium. As a reactor fuel loadout ages, power changes actually become faster because the U238 is converted to Pu239 over time.
A first year undergraduate engineering student would be able to build a reliable temperature monitor.
Right. Because there are so many combinations of materials that can withstand temperatures in the thousands of degrees F and the intense neutron flux in a commercial reactor core for any prolonged period. Core status is measured by the temperature of the water entering and leaving the core - the core power can be calculated by how much the water heats up. Safety limits are usually given in terms of power, because the behavior has to be calculated.
The British burned down the White House in the War of 1812. They did it in retaliation for the US burning down the Canadian parliament earlier in the war.
I RTFA and did not find how the battery actually produces power - is it with a typical steam turbine, or some novel new system? The compact size of the battery also raises some interesting engineering problems. The one I am most interested is shielding - if there is not enough shielding between the reactor and the cooling parts, the radiation will corrode the parts to the point of failure, which is bad especially underground. It does make a lot of sense to use this for remote outposts like mining though.
Not a problem with the Far Cry 2 PC port - it creates a new save file every time you hit the quicksave key. I discovered this when my quicksave button didn't work any more, apparently because my save folder was ~3.5 gigs with ~600 quicksaves in it. I did take the chance to go back a few saves.
I've heard the PC version is a fairly decent port, with the ratings approximately equal to the console versions. Does this mean that quality won't be an issue for how well the game sells?
Seriously. Laws used to have "sunset clauses" that would cancel the law a few years after it was enacted unless it was voted otherwise. I understand that some New Deal era laws that are detrimental, like some subsidies, are still in existance because they were not given sunset clauses a few senators threaten to filibuster their repeal. Bringing this sort of policy back to laws would probably do wonders in convincing congresspeople into considering new possibilities.
The music that plays in the menu when you first start the game up is important for setting the tone of the game. The music for the game Mafia was absolutely masterful at this.

Let's use Bing because it has one syllable. Plus, would you rather "Google" your friend's sister or "Bing" her?
How about the long distance phone excise tax that was levied to fund the Spanish American War (in 1899) and finally repealed in 2006?

That's dumbing up.

Here's a useful book for you.
No, it needs to scream "BOOM HEADSHOT!!!" after after shot.

No, you can only have it in a dessert.

Screw that!
Wouldn't the fact that the material is by Dickens and Austen be enough to stop copying? I, for one, wouldn't pirate it if you paid me.
