English Language & Usage: Multi-Layered Discourse Room

9:57 PM

@JohanLarsson: I took the introductory course in English at LU back in the autumn of 2011, and did not continue

@JohanLarsson: If I had had an infinite amount of time I would have gone on, and probably tried some other languages as well

I newer took any language courses while at uni, the literature was mostly in English though.

what field did you study, then?

Master in mechanical engineering

ah, a fellow engineer :)

I'm doing robotics research :)

phd?

10:02 PM

yes

nice, sounds fun

it's very stimulating work

You know your Denavit–Hartenberg parameters then

I've heard the term, and I have some kind of grasp..

my focus is computer vision, so it's mostly mathematics

nice, sounds like you want to work where I work

10:07 PM

which is? ABB?

Sandvik, can't tell much more here

ah

what language do you program in?

I've played around a little with Halcon from C# at work

mostly python, but c and c++ are nice for some things

python has very nice plotting capabilities, and it's easy to do matrix computations

I never used Python, it has been on my list for a while, hear nice things about it

Do you use any libraries for the vision stuff?

10:13 PM

I use opencv a lot

often there are nontrivial tasks which are not exactly the focus of my research, and it's nice to have state-of-the-art implementations ready to be used without going into the details

but I should be going.. time to sleep

bye

nite

Q: Allow Entrance Into

I have a question about some usage problem: The door allows entrance into the building. The ticket allows entrance into the building. Sentence 1 seems good English. But sentence 2 seems weird. A ticket is not in the same class of objects as a door. A ticket does not physically block a...

Indeed.

how could you tell?

10:28 PM

Firstly, his titles are almost always a clue.

Most of his questions are about prepositions.

you are not worried about a false positive?

kinda harsh welcome to SE if you were wrong

Truth.

Got ’em, thanks.

So transparent.

Two Ns, evenn.

Againn.

10:32 PM

@JohanLarsson go get yourself a flag if you want.

I don't have an account

I wonder when I’ll pass @Sim.

The wizened up to the double-flag trick, though.

@tchrist sim had 500 flags before being elected mod.

I suppose you meant BST flags, though.

No, she didn’t. She had like 947. :)

O_O

10:35 PM

I have 836.

I'm still under 250. ._.

I'll have 240 whenever this is addressed.

You know, I do have believe that I’ve just come up with another curious feature or three for to train my expert-system on.

You don't say.

Trivial to feed that to a machine-learning algorithm.

I want to be the 5th Marshal.

10:38 PM

the question is fine in itself right?

@cornbreadninja麵包忍者 Endeavour to persevere.

@JohanLarsson This is an excuse?

@tchrist I shall.

@tchrist a lame one. For some reason I feel I should not have an ELU account, would be hubris.

@JohanLarsson Oh. I see. That is a respectable position, and I commend you. However, do you know how many utter and completely blathering analphabetic idiots have accounts there?

Q: How high’s the water now, Mable?

A: Up halfway between Saturn and Neptune, Otis.

Oh dear.

10:43 PM

Boulder Creek is risen again.

So.

Tired.

@tchrist Sounds like there are a couple, ELU does not need one more.

Of.

This.

spam has no wiki summary, will you help us create it?

Heh.

Dinner time.

10:47 PM

@tchrist can't even imagine

Video from Jamestown.

Roads chewed up like sand castles, like so many tales of lives writ in water.

That doesn’t yet count today. Normal is the data at 9/10. From here.

Cubic feet per second?

A lot of the waterways lost their sensors.

Yes.

Cubic feet, but yes.

ty

log scale would probably be a nicer fit

Looked up the number, like Lainioälven in summer

Found a somewhat interesting fact, looks like high flow in spring is about 10x normal flow on average

11:10 PM

Interesting.

this place is a decent match for 140 m^3/s

> Estimated 35 bridges need repair; 100 minor structures; estimated 100 miles of road damaged. Estimated $100-150 million in damage. Focus is to gain access to all communities by road.

@tchrist data here, if you bother translating they publish a lot of historical data.

A controlled spill is even better than a regular non-breaching spill.

high capacity emergency tunnels from the dams to the sea could be an effective way to mitigate disaster in the future

11:20 PM

But a tunnel of several thousand km...

it needs no pumps

I don't know...

The inclination may be too low for the water to stream away.

they make tunnels from the dams already, my dad used to work in constructing them long ago

Over a short distance, right?

dunno how long they were, probably very expensive

11:22 PM

A tunnel of a few hundred metres is already quite expensive.

yes

A canal is cheaper.

And you only need to reach a lower region, not the sea.

canal has the erosion problem but sure

Or, rather sedimentation.

Just like a tunnel.

@Cerberus I mean water escaping and cutting through the walls

11:26 PM

Walls?

walls of the canal

If they are eroded, there will be more sand beyond them?

the water deciding to make a new path

That takes a very long time.

not when it rains like in Boulder I think

11:28 PM

They require occasional maintenance.

If the canal becomes broader in a certain area, that's not a huge problem.

Just don't build a road next to it.

But maybe canals are still too expensive.

there is an upside to the tunnels, nice efficiency for the power generation

probably not enough to pay for them though

@JohanLarsson How do you mean?

If there is a nearby area where you could dump the excess water, and it leads through a narrow area of high rocks, then, sure, you can dig a tunnel.

So where do the tunnels lead to that you mentioned?

@Cerberus minimal flow losses, should enable nice % of potential energy turned into electricity. Guessing a bit here

If you have a situation like the one I described, sure.

@Cerberus did not find anything other than that it is 173 m below the level of the dam

11:42 PM

> Fallhöjd

Nice.

So apparently there is a much lower areas close by, and the water will do no damage there.

And a canal may be more expensive if the rocks are very high.

16 km long 11*11 m cross section. strange that it is not circular

So then you dig a tunnel, why not?

Hmm.

Drills are normally circular, this is true.

Perhaps it was sawed rather than dug?

16 km is long!

it says they used dynamite to make it

Ah.

wonder if they would do that today

11:45 PM

Use dynamite?

BRB

@Cerberus it was done with the sole purpose of efficiency, I think.

@Cerberus yeah, feels like they drill most things today

@JohanLarsson And who is going to build a 2,000 mile tunnel to the sea?
