  2. Inversion of control - Wikipedia

    en.wikipedia.org/wiki/Inversion_of_control

    Inversion of control makes the framework extensible by the methods defined by the application programmer. [3] Event-driven programming is often implemented using IoC so that the custom code need only be concerned with the handling of events, while the event loop and dispatch of events/messages is handled by the framework or the runtime ...

  3. Convention over configuration - Wikipedia

    en.wikipedia.org/wiki/Convention_over_configuration

    A software framework based on convention over configuration often involves a domain-specific language with a limited set of constructs or an inversion of control in which the developer can only affect behavior using a limited set of hooks, both of which can make implementing behaviors not easily expressed by the provided conventions more ...

  4. Index of coincidence - Wikipedia

    en.wikipedia.org/wiki/Index_of_coincidence

    This count, either as a ratio of the total or normalized by dividing by the expected count for a random source model, is known as the index of coincidence, or IC or IOC [2] or IoC [3] for short. Because letters in a natural language are not distributed evenly , the IC is higher for such texts than it would be for uniformly random text strings.

  5. Dependency injection - Wikipedia

    en.wikipedia.org/wiki/Dependency_injection

    Under inversion of control, the framework first constructs an object (such as a controller), and then passes control flow to it. With dependency injection, the framework also instantiates the dependencies declared by the application object (often in the constructor method's parameters), and passes the dependencies into the object. [8]

  6. Protective relay - Wikipedia

    en.wikipedia.org/wiki/Protective_relay

    An overcurrent relay is a type of protective relay which operates when the load current exceeds a pickup value. It is of two types: instantaneous over current (IOC) relay and definite time overcurrent (DTOC) relay. The ANSI device number is 50 for an IOC relay or a DTOC relay. In a typical application, the over current relay is connected to a ...

  7. Dependency graph - Wikipedia

    en.wikipedia.org/wiki/Dependency_graph

    In mathematics, computer science and digital electronics, a dependency graph is a directed graph representing dependencies of several objects towards each other. It is possible to derive an evaluation order or the absence of an evaluation order that respects the given dependencies from the dependency graph.

  8. List of arbitrary-precision arithmetic software - Wikipedia

    en.wikipedia.org/wiki/List_of_arbitrary...

    dc: "Desktop Calculator" arbitrary-precision RPN calculator that comes standard on most Unix-like systems. KCalc, Linux based scientific calculator; Maxima: a computer algebra system which bignum integers are directly inherited from its implementation language Common Lisp. In addition, it supports arbitrary-precision floating-point numbers ...

  9. Dependency inversion principle - Wikipedia

    en.wikipedia.org/wiki/Dependency_inversion_principle

    In object-oriented design, the dependency inversion principle is a specific methodology for loosely coupled software modules.When following this principle, the conventional dependency relationships established from high-level, policy-setting modules to low-level, dependency modules are reversed, thus rendering high-level modules independent of the low-level module implementation details.
