https://en.wikipedia.org/wiki/Levi%20graph
In combinatorial mathematics, a Levi graph or incidence graph is a bipartite graph associated with an incidence structure. From a collection of points and lines in an incidence geometry or a projective configuration, we form a graph with one vertex per point, one vertex per line, and an edge for every incidence between...
https://en.wikipedia.org/wiki/Floating%20ground
Most electrical circuits have a ground which is electrically connected to the Earth, hence the name "ground". The ground is said to be floating when this connection does not exist. Conductors are also described as having a floating voltage if they are not connected electrically to another non-floating (grounded) condu...

https://en.wikipedia.org/wiki/Kaonic%20hydrogen
Kaonic hydrogen is an exotic atom consisting of a negatively charged kaon orbiting a proton. Such particles were first identified, through their X-ray spectrum, at the KEK proton synchrotron in Tsukuba, Japan in 1997. More detailed studies have been performed at DAFNE in Frascati, Italy. Kaonic hydrogen has been creat...

https://en.wikipedia.org/wiki/Arbitrarily%20varying%20channel
An arbitrarily varying channel (AVC) is a communication channel model used in coding theory, and was first introduced by Blackwell, Breiman, and Thomasian. This particular channel has unknown parameters that can change over time and these changes may not have a uniform pattern during the transmission of a codeword. u...
https://en.wikipedia.org/wiki/Rete%20algorithm
The Rete algorithm ( , , rarely , ) is a pattern matching algorithm for implementing rule-based systems. The algorithm was developed to efficiently apply many rules or patterns to many objects, or facts, in a knowledge base. It is used to determine which of the system's rules should fire based on its data store, its...
