Well, you still have to filter out your harmonics, but the upside (to other users) is that if the bands you use are harmonically related, your failure to produce a clean signal mostly is an issue for other users of the same class - rather t

Pedantically speaking, that's more of a key extraction tool than a decryption tool as such. Most efficient, though.

I am Norwegian, our kroner are somewhat less sought after than the Danish krone. As for the cost in 1950, I have no idea except what my grandmother told me - but the 7,000kr average annual pay I looked up at the bureau of statistics. My pat

I'll recycle a comment I made in another thread a few years ago: When clearing out my grandmother's house a few years ago, my uncle and I almost broke our backs trying to get the freezer out. It felt like it weighed a ton, even em

Presumably because that was the orientation the spacecraft was asked to get to before comms was lost. Also, it is possible that 2 degrees of misalignment still allows some fraction of the signal to be detected, but it not being strong enoug

Well, money will only buy you freedom in such places until you annoy someone with deeper pockets than you have sufficiently so that they want you to wind up behind bars. Corruption is an equal opportunity weapon.

Wow, I've been using Mitsubishi Hi-Unis as my go-to pencils for decades now, and always assumed they were part of The(tm) Mitsubishi group. IMHO they outrank anything as all-round pencils - I mostly use mine in H grade for writing, occ

I seem to recall reading in The Economist years and years ago that this was largely a result of countless mergers and acquisitions and a strong cultural distaste for whittling away units not part of what was defined as the business' co

But (and this is my electronics engineer mind still trying to wrap my head around this) - when you pressurize a vessel made from composites, the tensile strength helps keep it all together, which is trivially intuitive. When the same vessel

-This was interesting, thanks! It appears they utilize a passive system to dampen the effect of vessel movement, whereas in many (most?) other cases compensation is done actively by the traction unit (the twin drums with the rope looped ove

In the cases I've been involved in, it has largely been oil companies or their subcontractors footing the bill, occasionally scientists or, uh, treasure hunters. (I work for a company making this exact type of recovery gear, so every n

But - sincere question, as I am largely ignorant on such matters: Those pressure vessels made from composites usually are used to contain a pressure on the inside, taking advantage of the excellent tensile strength of the carbon fibers, no?

I have never hauled submersible wrecks from the seabed, but have recovered lots of other stuff from the same place. Depending on the weight and bulk of the component, you'd likely do one out of three (at this depth; in shallower waters

Should be within the realm of the possible to use a kevlar-reinforced umbilical with fiber optics in it going to a buoy on the surface, though. Starlink to the rescue! I am not sure you would need that much bandwidth from down there, though

In some cases, the art may also be stolen to divert resources from other investigations, or, for that matter, to use as a bargaining chip with authorities. (When one of Edvard Munch's 'The Scream' paintings was last stolen, i

You hear those in conventional subs, too, as you go deeper the hull makes all sorts of worrying creaks. (During a sea trial, I had to be aboard a sub from $NAVY diving to 900 feet and change - the crew assured me the sounds were normal...)

Well, you need to be able to change the weight of the capsule somehow, otherwise you'd be stuck bobbing at the surface. (Or at the seabed). The puzzling bit, from what I have gathered, is that the ballast is not fail safe.
202.
by lb1lf 3y ago
The capsule itself is positively buoyant. As long as it can jettison the ballast (and is not tangled up in something on the seabed, say, the Titanic), it will come to the surface.

While the banging noise may have other origins, it sure sounds encouraging to the rescue effort underway. However, I struggle to see how the submersible (or, more precisely, its passengers) can be rescued in time - not only does it need to

That's how you bring several kW of power down to an ROV. An umbilical cable, copper conductors and fiber optics inside steel wire sheath. The weight of the thing makes it impossible to attach it directly to the ROV - It would be unmane

If the sub was designed like a few other deep-sea craft I've looked at, they'd have positive buoyancy and weights to overcome this; the idea being that having to blow ballast tanks at 400 bar pressure differential is rather inconv

In a similar vein, John Kraus (Of Antennas... textbook fame) described a gravitational transmitting and receiving system as a fun (?) diversion near the end of the book. It has been a few years, but I seem to recall that the transmitter was

I suspect it was an early attempt at machine translation, or perhaps that the translators are paid so bad there is no incentive to pause even for a moment to evaluate if the translation makes sense in context.
