  2. Pomodoro Technique - Wikipedia

    en.wikipedia.org/wiki/Pomodoro_Technique

    Set the Pomodoro timer (typically for 25 minutes). [1] Work on the task. End work when the timer rings and take a short break (typically 5–10 minutes). [5] Go back to Step 2 and repeat until you complete four pomodori. After four pomodori are done, take a long break (typically 20 to 30 minutes) instead of a short break.

  3. Timestamp - Wikipedia

    en.wikipedia.org/wiki/Timestamp

    17 minutes — an arbitrary minute counter that increments every 1 minute since its last manual "reset" event; Sequence number: 21 — a unitless counter that indicates only the relative order of events; this is event #21, which comes after 20 and before 22

  4. Repeater (horology) - Wikipedia

    en.wikipedia.org/wiki/Repeater_(horology)

    The 13 in (33 cm) watch by Louis Brandt (1892) was the first wristwatch with a minute repeater. The movement was manufactured by Audemars Piguet.. A repeater is a complication in a mechanical watch or clock that chimes the hours and often minutes at the press of a button.

    In the context of a rocket launch, the "L minus Time" is the physical time before launch, e.g. "L minus 3 minutes and 40 seconds". "T minus Time" is a system to mark points at which actions necessary for the launch are planned - this time stops and starts as various hold points are entered, and so doesn't show the actual time to launch.

  6. Discrete-event simulation - Wikipedia

    en.wikipedia.org/wiki/Discrete-event_simulation

    A discrete-event simulation (DES) models the operation of a system as a sequence of events in time. Each event occurs at a particular instant in time and marks a change of state in the system. [ 1 ] Between consecutive events, no change in the system is assumed to occur; thus the simulation time can directly jump to the occurrence time of the ...

  7. Mengenlehreuhr - Wikipedia

    en.wikipedia.org/wiki/Mengenlehreuhr

    The Mengenlehreuhr clock face utilizes 24 light switches (1+4+4+11+4=24) to display time in 0-24 hour, 0-59 minute and even/odd second. Second : The top big circular light is the second mark. Since 0 is represented as an OFF in the most logical circuit, It’s an even second when the light is OFF.

  8. Counter (digital) - Wikipedia

    en.wikipedia.org/wiki/Counter_(digital)

    Decade counter – modulus ten counter (counts through ten states). Up/down counter – counts up and down, as directed by a control input, or by the use of separate "up" and "down" clocks. Ring counter – formed by a "circular" shift register. Johnson counter – a twisted ring counter. Gray-code counter – outputs a sequence of Gray codes.

  9. Single-machine scheduling - Wikipedia

    en.wikipedia.org/wiki/Single-machine_scheduling

    Single-machine scheduling or single-resource scheduling is an optimization problem in computer science and operations research.We are given n jobs J 1, J 2, ..., J n of varying processing times, which need to be scheduled on a single machine, in a way that optimizes a certain objective, such as the throughput.
