The tube resembled a small cathode ray tube (CRT). Monoscopes were used beginning in the 1950s to generate TV test patterns and station logos. This type of test card generat... |
https://en.wikipedia.org/wiki/Feature-driven%20development | Feature-driven development (FDD) is an iterative and incremental software development process. It is a lightweight or Agile method for developing software. FDD blends a number of industry-recognized best practices into a cohesive whole. These practices are driven from a client-valued functionality (feature) perspective... |
https://en.wikipedia.org/wiki/Betavoltaic%20device | A betavoltaic device (betavoltaic cell or betavoltaic battery) is a type of nuclear battery which generates electric current from beta particles (electrons) emitted from a radioactive source, using semiconductor junctions. A common source used is the hydrogen isotope tritium.
Unlike most nuclear power sources which us... |
https://en.wikipedia.org/wiki/Burst%20noise | Burst noise is a type of electronic noise that occurs in semiconductors and ultra-thin gate oxide films. It is also called random telegraph noise (RTN), popcorn noise, impulse noise, bi-stable noise, or random telegraph signal (RTS) noise.
It consists of sudden step-like transitions between two or more discrete volta... |
https://en.wikipedia.org/wiki/Wave%20front%20set | In mathematical analysis, more precisely in microlocal analysis, the wave front (set) WF(f) characterizes the singularities of a generalized function f, not only in space, but also with respect to its Fourier transform at each point. The term "wave front" was coined by Lars Hörmander around 1970.

https://en.wikipedia.org/wiki/Transformation%20%28function%29 | In mathematics, a transformation is a function f, usually with some geometrical underpinning, that maps a set X to itself, i.e. .
Examples include linear transformations of vector spaces and geometric transformations, which include projective transformations, affine transformations, and specific affine transformations,... |
https://en.wikipedia.org/wiki/Pannus | Pannus is an abnormal layer of fibrovascular tissue or granulation tissue. Common sites for pannus formation include over the cornea, over a joint surface (as seen in rheumatoid arthritis), or on a prosthetic heart valve. Pannus may grow in a tumor-like fashion, as in joints where it may erode articular cartilage and b... |
https://en.wikipedia.org/wiki/Mantis%20Bug%20Tracker | Mantis Bug Tracker is a free and open source, web-based bug tracking system. The most common use of MantisBT is to track software defects. However, MantisBT is often configured by users to serve as a more generic issue tracking system and project management tool.
The name Mantis and the logo of the project refer to th... |
https://en.wikipedia.org/wiki/Flexible-fuel%20vehicle | A flexible-fuel vehicle (FFV) or dual-fuel vehicle (colloquially called a flex-fuel vehicle) is an alternative fuel vehicle with an internal combustion engine designed to run on more than one fuel, usually gasoline blended with either ethanol or methanol fuel, and both fuels are stored in the same common tank. Modern f... |
