https://en.wikipedia.org/wiki/Open%20%28system%20call%29 | For most file systems, a program initializes access to a file in a file system using the open system call. This allocates resources associated to the file (the file descriptor), and returns a handle that the process will use to refer to that file. In some cases the open is performed by the first access.

https://en.wikipedia.org/wiki/Enumerative%20geometry | In mathematics, enumerative geometry is the branch of algebraic geometry concerned with counting numbers of solutions to geometric questions, mainly by means of intersection theory.
History
The problem of Apollonius is one of the earliest examples of enumerative geometry. This problem asks for the number and constru... |
https://en.wikipedia.org/wiki/Opera%20Mini | Opera Mini is a mobile web browser made by Opera. It was primarily designed for the Java ME platform, as a low-end sibling for Opera Mobile, but only the Android build was still under active development. It had previously been developed for iOS, Windows 10 Mobile, Windows Phone 8.1, BlackBerry, Symbian, and Bada.

https://en.wikipedia.org/wiki/Line%20spectral%20pairs | Line spectral pairs (LSP) or line spectral frequencies (LSF) are used to represent linear prediction coefficients (LPC) for transmission over a channel. LSPs have several properties (e.g. smaller sensitivity to quantization noise) that make them superior to direct quantization of LPCs. For this reason, LSPs are very us... |
https://en.wikipedia.org/wiki/Structural%20health%20monitoring | Structural health monitoring (SHM) involves the observation and analysis of a system over time using periodically sampled response measurements to monitor changes to the material and geometric properties of engineering structures such as bridges and buildings.
In an operational environment, structures degrade with age... |
https://en.wikipedia.org/wiki/Non-functional%20requirement | In systems engineering and requirements engineering, a non-functional requirement (NFR) is a requirement that specifies criteria that can be used to judge the operation of a system, rather than specific behaviours. They are contrasted with functional requirements that define specific behavior or functions. The plan for... |
https://en.wikipedia.org/wiki/Electrolyte%E2%80%93insulator%E2%80%93semiconductor%20sensor | Within electronics, an Electrolyte–insulator–semiconductor (EIS) sensor is a sensor that is made of these three components:
an electrolyte with the chemical that should be measured
an insulator that allows field-effect interaction, without leak currents between the two other components
a semiconductor to register t... |
https://en.wikipedia.org/wiki/RNSAP | RNSAP (Radio Network Subsystem Application Part) is a 3GPP signalling protocol responsible for communications between RNCs Radio Network Controllers defined in 3GPP specification TS 25.423. It is carried on the lur interface and provides functionality needed for soft handovers and SRNS (Serving Radio Network Subsystem... |
https://en.wikipedia.org/wiki/CHAIN%20%28industry%20standard%29 | The CECED Convergence Working Group has defined a new platform, called CHAIN (Ceced Home Appliances Interoperating
Network), which defines a protocol for interconnecting different home appliances in a single multibrand system.
It allows for control and automation of all basic appliance-related services in a home: e.g.... |
https://en.wikipedia.org/wiki/Software%20visualization | Software visualization or software visualisation refers to the visualization of information of and related to software systems—either the architecture of its source code or metrics of their runtime behavior—and their development process by means of static, interactive or animated 2-D or 3-D visual representations of th... |
https://en.wikipedia.org/wiki/Ternary%20Golay%20code | In coding theory, the ternary Golay codes are two closely related error-correcting codes.
The code generally known simply as the ternary Golay code is an -code, that is, it is a linear code over a ternary alphabet; the relative distance of the code is as large as it possibly can be for a ternary code, and hence, the te... |
https://en.wikipedia.org/wiki/Giant%20cell | A giant cell (also known as a multinucleated giant cell, or multinucleate giant cell) is a mass formed by the union of several distinct cells (usually histiocytes), often forming a granuloma. Although there is typically a focus on the pathological aspects of multinucleate giant cells (MGCs), they also play many importa... |
