https://en.wikipedia.org/wiki/Ridge%20detection | In image processing, ridge detection is the attempt, via software, to locate ridges in an image, defined as curves whose points are local maxima of the function, akin to geographical ridges.
For a function of N variables, its ridges are a set of curves whose points are local maxima in N − 1 dimensions. In this respec... |

When digitally signing a document, the integrity of the signature relies not just on the soundn... |
https://en.wikipedia.org/wiki/VP/CSS | VP/CSS was a time-sharing operating system developed by National CSS. It began life in 1968 as a copy of IBM's CP/CMS, which at the time was distributed to IBM customers at no charge, in source code form, without support, as part of the IBM Type-III Library. Through extensive in-house development, in what today would b... |
https://en.wikipedia.org/wiki/Perifocal%20coordinate%20system | The perifocal coordinate (PQW) system is a frame of reference for an orbit. The frame is centered at the focus of the orbit, i.e. the celestial body about which the orbit is centered. The unit vectors and lie in the plane of the orbit. is directed towards the periapsis of the orbit and has a true anomaly () of 90 d... |
https://en.wikipedia.org/wiki/Global%20network%20positioning | Global network positioning is a coordinates-based mechanism in a peer-to-peer network architecture which predicts Internet network distance (i.e. round-trip propagation and transmission delay). The mechanism is based on absolute coordinates computed from modeling the Internet as a geometric space. Since end hosts maint... |

https://en.wikipedia.org/wiki/Hydroxybenzotriazole | Hydroxybenzotriazole (abbreviated HOBt) is an organic compound that is a derivative of benzotriazole. It is a white crystalline powder, which as a commercial product contains some water (~11.7% wt as the HOBt monohydrate crystal). Anhydrous HOBt is explosive.
It is mainly used to suppress the racemization of single-e... |

Its priority was the complet... |
https://en.wikipedia.org/wiki/Steady%20state%20%28electronics%29 | In electronics, steady state is an equilibrium condition of a circuit or network that occurs as the effects of transients are no longer important. Steady state is reached (attained) after transient (initial, oscillating or turbulent) state has subsided. During steady state, a system is in relative stability.
Steady st... |
https://en.wikipedia.org/wiki/Miles%20and%20Misra%20method | The Miles and Misra Method (or surface viable count) is a technique used in Microbiology to determine the number of colony forming units in a bacterial suspension or homogenate.
The technique was first described in 1938 by Miles, Misra and Irwin who at the time were working at the LSHTM. The Miles and Misra method has... |
https://en.wikipedia.org/wiki/Mix%20network | Mix networks are routing protocols that create hard-to-trace communications by using a chain of proxy servers known as mixes which take in messages from multiple senders, shuffle them, and send them back out in random order to the next destination (possibly another mix node). This breaks the link between the source of ... |
