The central, substantial or essential part of anything; the gist; the core; as, the kernel of an argument.
the essential center of a computer operating system, the core that provides basic services for all other parts of the operating system. Typically, a kernel (or any comparable center of an operating system) includes an interrupt handler that handles all requests or completed I/O operations that compete for the kernel's services, a scheduler that determines which programs share the kernel's processing time in what order, and a supervisor that actually gives use of the computer to each process when it is scheduled. A kernel may also include a manager of the operating system's address spaces in memory or storage, sharing these among all components and other users of the kernel's services. A kernel's services are requested by other parts of the operating system or by applications through a specified set of program interfaces known as system calls.
Core computer programs of an operating system. Allows hardware to interact with software. The Linux kernel is at the heard of the SCO-IBM lawsuit.
The kernel of the simulator is the component that acts as the main controller of all decisions made by the system. In other words, the kernel is the server of the simulator system. Since the kernel is essentially the main processing unit, all components associated with the system must be linked to the kernel itself. In general, the main tasks performed by the kernel consist of the communication with all components, integrating the intended effects from each simulator onto the world, initiating and continuously creating the overall situation of the world's grid field during each round, storing and retrieving information from the world information database, deciding what information is to be displayed on the viewers, and assembling and updating all information to and from all other agents.
The essential part of a seed; all that is within the seed walls; the edible substance contained in the shell of a nut; hence, anything included in a shell, husk, or integument; as, the kernel of a nut. See Illust. of Endocarp.
A single seed or grain; as, a kernel of corn.
the inner, usually edible part of a nut ( q.v.) or stone ( q.v.)
Whole grain of a cereal; the mature ovule.
A subset of the domain of a homomorphism consisting of all elements that map to the identity element. The kernel is always a sub-object of appropriate type. E. g. the kernel of a group homomorphism is a subgroup.
of a ring homomorphism It is the preimage of 0 in the codomain of a ring homomorphism. Every ideal is the kernel of a ring homomorphism and vice versa.
of a ring homomorphism The kernel is the preimage of the element 0 of the codomain of the ring homomorphism. Every ideal is the kernel of a ring homomorphism and vice versa.
In the various branches of mathematics that fall under the heading of abstract algebra, the kernel of a homomorphism measures the degree to which the homomorphism fails to be injective.
a functional unit that can be repeated as needed
a function which takes two entities ( and and computes a scalar
a parallel function applied to every element of the input streams
In mathematics, the kernel of a function f may be taken to be either
a matrix whose center corresponds to the source pixel and the other elements correspond to neighboring pixels
a small matrix sliding over the image matrix containing coefficients, which are multiplied to corresponding image matrix elements and their sum, is put at the target pixel
A pixel array used for digital image filtering.
