If you happen to have a large number of commons and uncommons from Lorwyn-Morningtide-Shadowmoor-Eventide, you may want to consider selling them off or trading them away. Some of them are now worth quite a bit, and with Lorwyn Eclipsed slated for January, there may be some reprints pending. #magicthegathering #mtg #mtglorwyn #lrw #mor #shm #eventide

A nice clear explanation of something which I'm sure a lot of people find a bit odd at first.

A cycloidal pendulum - one suspended from the cusp of an inverted cycloid - is isochronous, meaning its period is constant regardless of the amplitude of the swing. Please find the proof using energy methods: Lagrange's equations (in the images attached to the reply).

Background:
The standard pendulum period of \(2\pi\sqrt{L/g}\) or frequency \(\sqrt{g/L}\) holds only for small oscillations. The frequency becomes smaller as the amplitude grows. If you want to build a pendulum whose frequency is independent of the amplitude, you should hang it from the cusp of a cycloid of a certain size, as shown in the gif. As the string wraps partially around the cycloid, the effect decreases the length of the string in the air, increasing the frequency back up to a constant value.

In more detail:
A cycloid is the path taken by a point on the rim of a rolling wheel. The upside-down cycloid in the gif can be parameterized by \((x, y)=R(\theta-\sin\theta, -1+\cos\theta)\), where \(\theta=0\) corresponds to the cusp. Consider a pendulum of length \(L=4R\) hanging from the cusp, and let \(\alpha\) be the angle the string makes with the vertical, as shown (in the proof).

In diesem Beitrag wird ein probabilistisches Bayessches Framework zur Erkennung und Charakterisierung von Schäden an Tragwerken vorgestellt, das gleichzeitig Umwelteinflüsse berücksichtigt. Dies ermöglicht die Unterscheidung zwischen Änderungen im Tragwerksverhalten, die durch #Umwelteinflüsse (wie z.B. Temperaturschwankungen) verursacht werden, und solchen, die auf tatsächliche Schäden zurückzuführen sind.

Anyone aware of a #SHM (structural Health Monitoring) database that is freely available with data from europe?

I am curious to corelate some data from various sources

I am especially interested in building damage due to ground movement.

Strong words in the #SHM this morning: "This is a massive, weekly transfer of wealth from (generally speaking) young renters who supply a city with energy, creativity and dynamism to older property-owning classes who don’t. " #Sydney
