  2. One-step method - Wikipedia

    en.wikipedia.org/wiki/One-step_method

    is used. This well-known method was published by the German mathematician Wilhelm Kutta in 1901, after Karl Heun had found a three-step one-step method of order 3 a year earlier. [19] The construction of explicit methods of even higher order with the smallest possible number of steps is a mathematically quite demanding problem.

  3. Unity (user interface) - Wikipedia

    en.wikipedia.org/wiki/Unity_(user_interface)

    Unity 2D showing the ability to run alongside different window managers and desktop environments. Initially Canonical maintained two discrete versions of Unity, which were visually almost indistinguishable but technically different. Unity is written as a plugin for Compiz [38] and uses an uncommon OpenGL toolkit called Nux. [3]

  4. Conversion of units - Wikipedia

    en.wikipedia.org/wiki/Conversion_of_units

    The factor–label method, also known as the unit–factor method or the unity bracket method, [1] is a widely used technique for unit conversions that uses the rules of algebra. [ 2 ] [ 3 ] [ 4 ]

  5. Instruction step - Wikipedia

    en.wikipedia.org/wiki/Instruction_step

    An instruction step is a method of executing a computer program one step at a time to determine how it is functioning. This might be to determine if the correct program flow is being followed in the program during the execution or to see if variables are set to their correct values after a single step has completed.

  6. Step response - Wikipedia

    en.wikipedia.org/wiki/Step_response

    The step response of a system in a given initial state consists of the time evolution of its outputs when its control inputs are Heaviside step functions. In electronic engineering and control theory , step response is the time behaviour of the outputs of a general system when its inputs change from zero to one in a very short time.

  7. One-page management system - Wikipedia

    en.wikipedia.org/wiki/One-page_management_system

    The one-page management system (OPMS) is a set of methods to help people generate ideas through systematic brainstorming and to structure (or organize) ideas as needed for effective resolution of problems. G. S. Chandy invented OPMS, based on John N. Warfield's "interactive management" and "structural approach to system design". [1]

  9. Per-unit system - Wikipedia

    en.wikipedia.org/wiki/Per-unit_system

    In the power systems analysis field of electrical engineering, a per-unit system is the expression of system quantities as fractions of a defined base unit quantity. . Calculations are simplified because quantities expressed as per-unit do not change when they are referred from one side of a transformer to t
