Here are my favorite valentine's day cards! Feel free to send me more!
Check out these: mastodon.social/@anubiarts/111 by @…

A valentine's day card edited only using free and open source software saying “what if we kissed exchanged our public key” The page shows many cute emojis, hearts, the GIMP paprika, and a gpg public key import log text.
A valentine's day card saying “Are you using KDE? Because you're a Qt” (Qt is pronounced like “cutie”
A valentine's day card saying “There is no union without you 'U' and 'I'” with the domain “MayDayStrike.org”

A stable decoupled perfectly matched layer for the 3D wave equation using the nodal discontinuous Galerkin method
In outdoor acoustics, the calculations of sound propagating in air can be computationally heavy if the domain is chosen large enough to fulfil the Sommerfeld radiation condition. By strategically truncating the computational domain with a efficient boundary treatment, the computational cost is lowered. One commonly used boundary treatment is the perfectly matched layer (PML) that dampens outgoing waves without polluting the computed solution in the inner domain. The purpose of this study is to …
