| Solving the N-pendulum algebraically. &[Wolfram Notebook][1] [1]: https://www.wolframcloud.com/obj/61a8da15-3502-4d34-a1b8-b3bb505ed0e1 |
| I'm new to SystemModeler and the underlying modeling Language Modelica. I would like to do model a [scissor mechanism][1] and I don't quite see how to do it within the Modelica Mechanics Library. I want an idealized model so I want to neglect... |
| Some time ago, before I had a Mathematica license, I solved the classical pendulum problem with only algebra and rational numbers : http://grondilu.github.io/pendulum.html I was inspired by Norman Wildberger who advocates on YouTube for what he... |
| Dt[x] /. Dt[h_] :> h (*surprisingly returns Dt[x], not x*) It seems to work with any other function than Dt. Log[x] /. Log[h_] :> h (*returns x*) Also I can do the substitution if I don't use a pattern : Dt[x] /. Dt[x] -> x... |
| Hi, I was experimenting with `NetGANOperator` and the training seemed to work fine as the loss function results were evolving more or less as I would have expected. However, when training was done, I tried to generate images from a few latent... |
| [DictionnaryLookup][1] searches for dictionary entries matching a given spelling pattern, but is there a way to search for entries matching a given *phonetic* pattern, possibly using the international phonetic alphabet instead of the dictionary's... |
| I had already posted something similar but with the new 12.3.1 function `ListLinePlot3D` it becomes even easier so I thought it was worth sharing. You can visualize a nucleic acid sequence in 3d with a few lines of code : ... |
| ![enter image description here][1] I'm sure there have been many proposals on how to do this. I gave it a try, and after a few painful attempts I came up with a visually decent result, without too much code (IMHO). Also I really wanted to use... |
| First of all I'd like to put as a disclaimer that I am not an expert in machine learning in any way whatsoever, I'm just an interested layman who occasionally thinks about these stuff, and tonight I'm bored under that lockdown and I feel like asking... |
| So I stumbled upon this work : https://people.eecs.berkeley.edu/~bmild/fourfeat/ It is related to a previous paper about Sine REpresentation Networks (SIREN): https://vsitzmann.github.io/siren/ I had tried to implement SIRENs on Mathematica... |
