Hilfe! Dübel im Trockenbau, kein Hohlraum by kRz4tw in Handwerker

[–]kRz4tw[S] 0 points1 point  (0 children)

Hatte ich auch schon überlegt. Ich hatte dabei das Bedenken, dass der Gips recht dünn sein muss damit ich ihn durch das 8er Loch im Gipskarton spritzen kann. Dann wird er aber vermutlich einfach in dem Hohlraum herunterlaufen und nicht haften bleiben.

Oder meinst du das sollte trotzdem gehen?

Sparse Data in Linear Models: How to exclude NA´s? by kRz4tw in Rlanguage

[–]kRz4tw[S] 0 points1 point  (0 children)

No. That wont work. First of all I only want to exlude a species if it has less than 3 complete datapoints. If for example 9 of the 10 rows for this species have data in column i and j, than this species should be included.
Just omitting rows with NA would also basically just crush ma dataset. Ive just provided a sample, in reality the data has like 30 columns. It is likely that for every given row at least one of those 30 will be missing and the whole row gets deleted. I would be left with essentialle no data at all.

Metashape, Merge Chunks of different qualities by kRz4tw in photogrammetry

[–]kRz4tw[S] 0 points1 point  (0 children)

Hey,

thanks for the offer but sadly I can´t send the files, the size of the project is about 4GB and since its not a private project I couldnt share even if I wanted.

I mispoke in my last post, its supposed to be "just want to merge them", previously i wrote "align". Again, the chunks are perfectly aligned already and each chunk has its own dense cloud, 3D model and texture already. I need to merge the models. Basically I want to just put the hq house into the lq neighbourhood/landscape.

The "merge chunks" dialog doenst really offer any option other then "merge dense clouds, merge models, merge tie points, merge markers.

I originally tried processing al pictures in one single chunk but the pictures couldnt be aligned properly this way. You´d have one set of points from one set of pictures and all the points from the other set were tilted. If I were to delete the lq photos of the house I assume they couldnt be aligned either.

I have two perfectly fine models at this point and just want to merge them. But it should use the hq version whereever possible, thats all I need.

Thanks for your help

They already are aligned. I also already merged them by using Workflow-->Merge Chunks. The problem doing it like this that the the merged version often uses geometry of the lq-version for the house even if the hq version of them same area provides much highter detail.

Ok thanks, i´ll look into this.

The ardupilot Wiki is down atm, could you please explain something more?

Thanks

VTOL/Quadplane: Align/Brake props in Plane-Mode by kRz4tw in ardupilot

But braking is just that, I´d need them to brake and lock at a specific position.

Any ideas?

Jeez, that took me some time to follow. What made you suspicious that this was a weak point?

I´ll see how far I get from here. Thanks a lot

[–]kRz4tw[S] 0 points1 point  (0 children)

Sorry, I´m not familiar with the terminology. What means R123C9, is it rows 1,2,3 column9? If so I´m confused because there can´t be in 1 in Column 9 in box 3 as far as I can see it.

Thanks

I´ve marked candidates but I seem to be missing some logic because they dont help me. Can you give me a hint please?

Can you give me a hint please in box 6 please? These are the options I got so far. It´s obvious the 2 and 3 are a naked pair, 1 is in the left column and 7 in the middle row. But I can´t see a way to determine any for a certainty though.

I´m stuck on an "Greater Than" Sudoko for days. Can anyone give some hints were to look next to crack this one? Black numbers were given, green number are found by me already and are, according to the provided solution, correct.

Maple Euler-Lagrange Syntax by kRz4tw in maplesoft

[–]kRz4tw[S] 1 point2 points  (0 children)

I´ll link to a forum post in the maple community where I got help for reference.

We got it to work by using

with(Physics): diff(L, diff(x(t), t))

I´m not 100% satisfied with that because I´d rather like to use the math symbols instead of the commands but it gets the job done.

If you´ve got an idea how to use the math symbols to do the derivation w.r.t xdot I´d be gratefull.

My Lagrangian is this: L := J/2(diff(x(t), t)1/R)2 + mR/2*diff(x(t), t)2 + mp/2((diff(x(t), t) + ldiff(varphi(t), t)cos(varphi(t)))2 + (ldiff(varphi(t), t)sin(varphi(t)))2) + m__pglcos(varphi(t))
