https://en.wikipedia.org/wiki/Apotome%20%28mathematics%29 | In the historical study of mathematics, an apotome is a line segment formed from a longer line segment by breaking it into two parts, one of which is commensurable only in power to the whole; the other part is the apotome. In this definition, two line segments are said to be "commensurable only in power" when the ratio... |

https://en.wikipedia.org/wiki/Image%20sensor | An image sensor or imager is a sensor that detects and conveys information used to form an image. It does so by converting the variable attenuation of light waves (as they pass through or reflect off objects) into signals, small bursts of current that convey the information. The waves can be light or other electromagne... |

https://en.wikipedia.org/wiki/Plaintext-aware%20encryption | Plaintext-awareness is a notion of security for public-key encryption. A cryptosystem is plaintext-aware if it is difficult for any efficient algorithm to come up with a valid ciphertext without being aware of the corresponding plaintext.
From a lay point of view, this is a strange property. Normally, a ciphertext i... |
https://en.wikipedia.org/wiki/Stygofauna | Stygofauna are any fauna that live in groundwater systems or aquifers, such as caves, fissures and vugs. Stygofauna and troglofauna are the two types of subterranean fauna (based on life-history). Both are associated with subterranean environments – stygofauna are associated with water, and troglofauna with caves and s... |
https://en.wikipedia.org/wiki/Subvocal%20recognition | Subvocal recognition (SVR) is the process of taking subvocalization and converting the detected results to a digital output, aural or text-based.
Concept
A set of electrodes are attached to the skin of the throat and, without opening the mouth or uttering a sound, the words are recognized by a computer.
Subvocal sp... |
