Common Expressions: kernel
| Expressions | Definition | ||
| Accent kernel | Accent was an operating system kernel developed at Carnegie Mellon University (CMU). Accent was developed as a follow-on to the Aleph kernel developed at the University of Rochester, fixing several of its problems and re-targeting its hardware support for networks of workstation machines instead of minicomputers. Accent was part of the SPICE Project at CMU which ran from 1981 to 1985. (references) | ||
| Aleph kernel | Aleph was an operating system kernel developed at the University of Rochester as part of their RIG project in 1975. Aleph used inter-process communications to move data between programs and the kernel, so applications could transparently access resources on any machine on the local area network (which at the time was a 3-Mbit/s experimental Xerox Ethernet). The project eventually petered out after several years due to rapid changes in the computer hardware market, but the ideas led to the creation of Accent at Carnegie Mellon University, leading in turn to Mach. (references) | ||
| Fejér kernel | In mathematics, the Fejér kernel is used to express the effect of Cesàro summation on Fourier series. It is a positive kernel, giving rise to an approximate identity. (references) | ||
| Fredholm kernel | In mathematics, a Fredholm kernel is a certain type of a kernel on a Banach space, associated with nuclear operators on the Banach space. Fredholm kernels are named for Ivar Fredholm. Much of the theory of Fredholm kernels was developed by Alexander Grothendieck and published in 1955. (references) | ||
| Graphical Kernel System | The Graphical Kernel System (GKS) was the first ISO standard for low level computer graphics, introduced in 1977. GKS provides a set of low-level drawing features for two-dimensional line and vector graphics. The calls are designed to be portable across different programming languages, graphics devices and uses, so that applications written to use GKS will be readily portable to many platforms and devices.

| Kernel (integral operator) | The function k(x,y) that appears in this formula is the kernel of the operator T. (references) | ||
| Kernel Normal Form | Kernel normal form, or KNF, is the normal form used in the development of code for the BSD operating systems. Based on a concept from Computer Systems Research Group's original KNF, this code style is used to dictate how contributed code must appear prior to it's inclusion into the codebase. (references) | ||
| Kernel of a function | For the formal definition, let X and Y be sets and let f be a function from X to Y. (references) | ||
| Kernel panic | A kernel panic is a message displayed by an operating system upon detecting an internal system error from which it cannot recover. Kernel panics often provide cryptic debugging information that is useful only to the developers of the operating system. (references) | ||
| Kernel trick | The kernel trick was first published in the 1964 paper Theoretical foundations of the potential function method in pattern recognition learning. It allows linear algorithms to be easily converted into non-linear algorithms. (references) | ||
| Kernel virtual address space | The Kernel Virtual Address Space (KVA) is the virtual memory area in which all Linux kernel threads reside. The second part of the virtual address space is occupied by the User Virtual Address Space which contain user threads. (references) | ||
| Light Weight Kernel Threads | Light Weight Kernel Threads or LWKT is a term from computer science in general and in DragonFlyBSD in particular. LWKTs differ from normal kernel threads in that they can preempt normal kernel threads. (references) | ||
| Linux Kernel API | The Linux Kernel API is an application programming interface providing a uniform method for device drivers and other low-level software written for the Linux kernel to access system resources and services. (references) | ||
| Linux Kernel Developers Summit | The Linux Kernel Developers Summit is a conference held every year where Linux kernel developers talk about current and future developments of the Linux kernel. (references) | ||
| Linux kernel mailing list | The Linux kernel mailing list (LKML) is a electronic mailing list focusing on the discussion of Linux kernel development. Many other mailing lists exist to discuss the different subsystems and ports of the linux kernel, but LKML provides the glue that holds the kernel development community together. It is a very high volume list, usually receiving between 200-300 messages a day. (references) | ||

| Poisson kernel | In potential theory, the Poisson kernel is the derivative of the Green's function for the two-dimensional Laplace equation, under circular symmetry, using Dirichlet boundary conditions (BCS). (references) | ||
| Reproducing kernel Hilbert space | In functional analysis (a branch of mathematics), a reproducing kernel Hilbert space is a function space in which pointwise evaluation is a continuous linear functional. Equivalently, they are spaces that can be defined by reproducing kernels. The subject was originally and simultaneously developed by N. Aronszajn and S. Bergman in 1950. (references) | ||
| Stochastic kernel | A stochastic kernel is the transition function of a (usually discrete) stochastic process. Often, it is assumed to be iid, thus a probability density function. (references) | ||
| The Kentucky Kernel | The Kentucky Kernel is the student newspaper of the University of Kentucky. The Kernel's first issue was in 1915, and it became a daily paper in 1966. In 1972, the Kernel gained financial independence from of the university, although its office remains on campus to this day. (references) | ||
| VA Kernel | The VA Kernel is a set of programs, developed by the Department of Veterans Affairs of the United States Government, which provide an operating system and MUMPS implementation independent abstraction to the VistA Hospital Information System. These programs (called 'routines' in MUMPS) are the only programs which are expected to not be written in ANSI Standard MUMPS. (references) | ||

| Kernel (Operator) | Space | A unit or array of pixels used in digital image filtering. A kernel is the moving window whose center pixel is altered depending on the parameter being filtered. The kernel is usually made up of an odd number of pixels (e.g. 3 x 3, 5 x 5, 7 x 7). The larger the kernel the greater the smoothing effect of the filter. (references) | |
