In essence this implies that the random process will not change its statistical properties with time and that its statistical properties (such as the theoretical mean and variance of the process)... |
https://en.wikipedia.org/wiki/Storage%20service%20provider | A Storage service provider (SSP) is any company that provides computer storage space and related management services. SSPs may also offer periodic backup and archiving.
Advantages of managed storage are that more space can be ordered as required. Depending upon your SSP, backups may also be managed.
Faster data access... |
https://en.wikipedia.org/wiki/Thomson%20problem | The objective of the Thomson problem is to determine the minimum electrostatic potential energy configuration of electrons constrained to the surface of a unit sphere that repel each other with a force given by Coulomb's law. The physicist J. J. Thomson posed the problem in 1904 after proposing an atomic model, later ... |

https://en.wikipedia.org/wiki/Disk%20pack | Disk packs and disk cartridges were early forms of removable media for computer data storage, introduced in the 1960s.
Disk pack
A disk pack is a layered grouping of hard disk platters (circular, rigid discs coated with a magnetic data storage surface). A disk pack is the core component of a hard disk drive. In moder... |
https://en.wikipedia.org/wiki/Phoning%20home | In computing, phoning home is a term often used to refer to the behavior of security systems that report network location, username, or other such data to another computer.
Phoning home may be useful for the proprietor in tracking a missing or stolen computer. In this way, it is frequently performed by mobile computer... |
https://en.wikipedia.org/wiki/Temporal%20mean | The temporal mean is the arithmetic mean of a series of values over a time period. Assuming equidistant measuring or sampling times, it can be computed as the sum of the values over a period divided by the number of values. A simple moving average can be considered to be a sequence of temporal means over periods of e... |
https://en.wikipedia.org/wiki/Iconoscope | The iconoscope (from the Greek: εἰκών "image" and σκοπεῖν "to look, to see") was the first practical video camera tube to be used in early television cameras. The iconoscope produced a much stronger signal than earlier mechanical designs, and could be used under any well-lit conditions. This was the first fully electro... |
https://en.wikipedia.org/wiki/Piezochromism | Piezochromism, from the Greek piezô "to squeeze, to press" and chromos "color", describes the tendency of certain materials to change color with the application of pressure. This effect is closely related to the electronic band gap change, which can be found in plastics, semiconductors (e.g. hybrid perovskites) and hyd... |
https://en.wikipedia.org/wiki/Confounding | In causal inference, a confounder (also confounding variable, confounding factor, extraneous determinant or lurking variable) is a variable that influences both the dependent variable and independent variable, causing a spurious association. Confounding is a causal concept, and as such, cannot be described in terms of... |
https://en.wikipedia.org/wiki/Rankine%20vortex | The Rankine vortex is a simple mathematical model of a vortex in a viscous fluid. It is named after its discoverer, William John Macquorn Rankine.
The vortices observed in nature are usually modelled with an irrotational (potential or free) vortex. However, in potential vortex, the velocity becomes infinite at the vor... |
https://en.wikipedia.org/wiki/RE%20%28complexity%29 | In computability theory and computational complexity theory, RE (recursively enumerable) is the class of decision problems for which a 'yes' answer can be verified by a Turing machine in a finite amount of time. Informally, it means that if the answer to a problem instance is 'yes', then there is some procedure that ta... |
https://en.wikipedia.org/wiki/R%20%28complexity%29 | In computational complexity theory, R is the class of decision problems solvable by a Turing machine, which is the set of all recursive languages (also called decidable languages).
Equivalent formulations
R is equivalent to the set of all total computable functions in the sense that:
a decision problem is in R if and ... |
https://en.wikipedia.org/wiki/G-Market | Gmarket is an e-commerce website based in South Korea. The company was founded in 2000 as a subsidiary of Interpark, and was acquired by eBay in 2009, who subsequently sold it to Shinsegae at 3.4 trillion Korean Won.
History and Incidents
The predecessor of Gmarket was founded in 1999 by Young Bae Ku. At the time, it ... |
https://en.wikipedia.org/wiki/Klee%27s%20measure%20problem | In computational geometry, Klee's measure problem is the problem of determining how efficiently the measure of a union of (multidimensional) rectangular ranges can be computed. Here, a d-dimensional rectangular range is defined to be a Cartesian product of d intervals of real numbers, which is a subset of Rd.
