The actual title reads quite clearly it's not about orbital mechanics: "Investigating the Luna-Terra Collapse through the Temporal Multilayer Graph Structure of the Ethereum Stablecoin Ecosystem"
This is the most likely reason. They should have put a sign, but the ramp looks right to me if you want them to match pedestrian speed when merging into a pedestrian space.
I am an Engineer and have done things both ways throughout my career. What is easy to miss in digital are the overall holistic design and the way it all fits together, because you are always zoomed in on a particular piece of the puzzle and rarely see the whole thing on screen in a meaningful way. There is just something about seeing a full design laid out on paper, spread out on the table, that lets many little things jump out at you.
This was obviously not a good system design, but a box full of relays and PLC controller cost a whole lot less than the all-in employer cost of an extra employee.
They really should also be able to turn off the lights at the breakers unless they did something exceptionally stupid like put the fire control panels on the lighting breakers.

Why would you need an extra employee just to turn on/off the lights? I think janitors or teachers always did that as part of the job before smart switches came around, no need to hire some "light manager".
Having read most of the comments debating the pros and cons of the system this is an astonishingly simple solution! Sometimes I think those of us in technology look for problems to solve.
The scary part is how much real interpersonal communication data they have on users and what could be done with it in the wrong hands. What is their real business model? It can't just be selling Nitro.
Discord watches what apps you launch, primarily games, and sells this data to others to determine what games to make, or what games people are playing. It’s the same purpose of all the game launchers out there that run even when you’re not playing a game from that company.
Because gaps like this multiply out at the end of a beam. If for example the abutting structural member relies on that joint for support and is 12 feet long (144 inches) and lets say the flange is 6" across, .005/6 x 144 = .12" which is about 1/8 of an inch of wiggle at the end. If your gap were, say .010" instead, there is suddenly 1/4" of wiggle and when things can wiggle like that vibration gets much worse.
I see no reason this thing wouldn't lose compression or backflow exhaust gas after wear-in, and wear-in would happen quickly with the cyclic load on those ball bearings. It's a pretty animation but unless they have some spring loading to press the upper and lower rings together the compression (and therefore efficiency) doesn't appear to be durable. There are also some limitations to having a single power stroke per revolution. This can be geared down, of course, but at an efficiency cost.
> There are also some limitations to having a single power stroke per revolution.
Unlike one power stroke per two revolutions? That engine has one stroke lasting a full revolution, modern four-stroke has power stroke lasting half of revolution, every two revolutions.
Guesses poorly too, based on the examples. The crack growth example is almost laughable. These are nowhere close to where real cracks would form. Cracks start on the inside corner of brittle joints.
The bar stretch is also completely wrong, there are no stress concentrations at the top and bottom; it should be uniform stress or concentrated strain in the center depending on what they're attempting to show.
The question is whether it can get better. Even small steps aggregate to great changes over time.
First CGA monitors were bulky, energy hungry and blurry at the same time. 40 years of continuous development, and I am staring at a nice 4K screen that does not strain my eyes and is substantially more energy efficient.
A static weld is usually stronger than the base metal under static conditions (i.e. not undergoing dynamic shock loading). Welds are created at 3000 degrees C with 50-100C metal right next to it. By the time a weld cools there are always captive stresses, meaning during a failure the weld is the most brittle part. This can be alleviated with pre and post weld heat treatment, but there are always stresses built into a weld.
