https://en.wikipedia.org/wiki/Black%20balance | Video cameras can possess a function called black balance which calibrates the signal for no light, just as they have a "white balance" function which gives reference to true white to the CCDs. Unlike white balance, black balance is not adjusted every time. This function is found in higher end 'professional' cameras r... |
https://en.wikipedia.org/wiki/Roland%20Glowinski | Roland Glowinski (9 March 1937 – 26 January 2022) was a French-American mathematician. He obtained his PhD in 1970 from Jacques-Louis Lions and was known for his work in applied mathematics, in particular numerical solution and applications of partial differential equations and variational inequalities. He was a member... |
https://en.wikipedia.org/wiki/Phase-gate%20process | A phase-gate process (also referred to as a waterfall process) is a project management technique in which an initiative or project (e.g., new product development, software development, process improvement, business change) is divided into distinct stages or phases, separated by decision points (known as gates).

https://en.wikipedia.org/wiki/Pseudo-abelian%20category | In mathematics, specifically in category theory, a pseudo-abelian category is a category that is preadditive and is such that every idempotent has a kernel. Recall that an idempotent morphism is an endomorphism of an object with the property that . Elementary considerations show that every idempotent then has a cokern... |
https://en.wikipedia.org/wiki/Edmund%20Mach%20Foundation | The Edmund Mach Foundation, formerly the Istituto Agrario di San Michele all’Adige (IASMA), is an agrarian institution and wine academy located in Trentino in north-east Italy. It was founded in 1874, when the Tyrolean Diet at Innsbruck decided to open an agrarian school and research station at San Michele all’Adige, w... |
https://en.wikipedia.org/wiki/Multiple-emitter%20transistor | A multiple-emitter transistor is a specialized bipolar transistor mostly used at the inputs of integrated circuit TTL NAND logic gates. Input signals are applied to the emitters. The voltage presented to the following stage is pulled low if any one or more of the base–emitter junctions is forward biased, allowing logic... |
https://en.wikipedia.org/wiki/Armstrong%20phase%20modulator | In 1933, Edwin H. Armstrong patented a method for generating frequency modulation of radio signals. The Armstrong method generates a double sideband suppressed carrier signal, phase shifts this signal, and then reinserts the carrier to produce a frequency modulated signal.
Frequency modulation generates high qualit... |
https://en.wikipedia.org/wiki/Fire%20Dynamics%20Simulator | Fire Dynamics Simulator (FDS) is a computational fluid dynamics (CFD) model of fire-driven fluid flow. The computer program solves numerically a large eddy simulation form of the Navier–Stokes equations appropriate for low-speed, thermally-driven flow, with an emphasis on smoke and heat transport from fires, to describ... |
https://en.wikipedia.org/wiki/Diaspore%20%28botany%29 | In botany, a diaspore is a plant dispersal unit consisting of a seed or spore plus any additional tissues that assist dispersal. In some seed plants, the diaspore is a seed and fruit together, or a seed and elaiosome. In a few seed plants, the diaspore is most or all of the plant, and is known as a tumbleweed.
Diaspo... |
https://en.wikipedia.org/wiki/Six-legged%20Soldiers | Six-Legged Soldiers: Using Insects as Weapons of War is a nonfiction scientific warfare book written by author and University of Wyoming professor, Jeffrey A. Lockwood. Published in 2008 by Oxford University Press, the book explores the history of bioterrorism, entomological warfare, biological warfare, and the prevent... |
https://en.wikipedia.org/wiki/Bochner%E2%80%93Riesz%20mean | The Bochner–Riesz mean is a summability method often used in harmonic analysis when considering convergence of Fourier series and Fourier integrals. It was introduced by Salomon Bochner as a modification of the Riesz mean.

https://en.wikipedia.org/wiki/Collage%20theorem | In mathematics, the collage theorem characterises an iterated function system whose attractor is close, relative to the Hausdorff metric, to a given set. The IFS described is composed of contractions whose images, as a collage or union when mapping the given set, are arbitrarily close to the given set. It is typically ... |
