  2. Orders of magnitude (time) - Wikipedia

    en.wikipedia.org/wiki/Orders_of_magnitude_(time)

    Orders of magnitude (time) An order of magnitude of time is usually a decimal prefix or decimal order-of-magnitude quantity together with a base unit of time, like a microsecond or a million years. In some cases, the order of magnitude may be implied (usually 1), like a "second" or "year". In other cases, the quantity name implies the base unit ...

  3. Vector clock - Wikipedia

    en.wikipedia.org/wiki/Vector_clock

    A vector clock is a data structure used for determining the partial ordering of events in a distributed system and detecting causality violations. Just as in Lamport timestamps, inter-process messages contain the state of the sending process's logical clock. A vector clock of a system of N processes is an array /vector of N logical clocks, one ...

  4. Time-invariant system - Wikipedia

    en.wikipedia.org/wiki/Time-invariant_system

    The time-dependent system function is a function of the time-dependent input function. If this function depends only indirectly on the time-domain (via the input function, for example), then that is a system that would be considered time-invariant. Conversely, any direct dependence on the time-domain of the system function could be considered ...

  5. Piping and instrumentation diagram - Wikipedia

    en.wikipedia.org/wiki/Piping_and_instrumentation...

    A piping and instrumentation diagram (P&ID) is defined as follows: A diagram which shows the interconnection of process equipment and the instrumentation used to control the process. In the process industry, a standard set of symbols is used to prepare drawings of processes. The instrument symbols used in these drawings are generally based on ...

  6. Time-variant system - Wikipedia

    en.wikipedia.org/wiki/Time-variant_system

    A time-variant system is a system whose output response depends on moment of observation as well as moment of input signal application. [1] In other words, a time delay or time advance of input not only shifts the output signal in time but also changes other parameters and behavior. Time variant systems respond differently to the same input at ...

  7. Sinclair BASIC - Wikipedia

    en.wikipedia.org/wiki/Sinclair_BASIC

    Sinclair BASIC is a dialect of the programming language BASIC used in the 8-bit home computers from Sinclair Research, Timex Sinclair and Amstrad. The Sinclair BASIC interpreter was written by Nine Tiles Networks Ltd. [1] Designed to run in only 1 kB of RAM, the system makes a number of decisions to lower memory usage.

  8. Lambda 8300 - Wikipedia

    en.wikipedia.org/wiki/PC_8300

    Command input is done key by key (not by keyword entry like on the ZX81). [3] The computer was somewhat successful in Northern Europe (mostly in Denmark and Norway ) and China, and today enthusiasts still develop new hardware.

  9. Discrete-event simulation - Wikipedia

    en.wikipedia.org/wiki/Discrete-event_simulation

    A discrete-event simulation ( DES) models the operation of a system as a ( discrete) 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 ...
