  2. Lasswell's model of communication - Wikipedia

    en.wikipedia.org/wiki/Lasswell's_model_of...

    These questions pick out the five fundamental components of the communicative process: the sender, the message, the channel, the receiver, and the effect. Some theorists have raised doubts that the widely used characterization as a model of communication is correct and refer to it instead as "Lasswell's formula", "Lasswell's definition", or ...

    A more complex example of a P&ID. 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.

    s. -process. The slow neutron-capture process, or s-process, is a series of reactions in nuclear astrophysics that occur in stars, particularly asymptotic giant branch stars. The s -process is responsible for the creation ( nucleosynthesis) of approximately half the atomic nuclei heavier than iron . In the s -process, a seed nucleus undergoes ...

  6. Bernoulli process - Wikipedia

    en.wikipedia.org/wiki/Bernoulli_process

    Probability theory. In probability and statistics, a Bernoulli process (named after Jacob Bernoulli) is a finite or infinite sequence of binary random variables, so it is a discrete-time stochastic process that takes only two values, canonically 0 and 1. The component Bernoulli variables Xi are identically distributed and independent.

  7. Process control block - Wikipedia

    en.wikipedia.org/wiki/Process_control_block

    A process control block (PCB), also sometimes called a process descriptor, is a data structure used by a computer operating system to store all the information about a process. When a process is created (initialized or installed), the operating system creates a corresponding process control block, which specifies and tracks the process state (i ...

  8. Five whys - Wikipedia

    en.wikipedia.org/wiki/Five_whys

    In this example, the fifth "why" suggests a broken process or an alterable behavior, which is indicative of reaching the root-cause level. This nature of the answer to the fifth why in the example is an important aspect of the five why approach. The real root cause should point toward a process that is not working well or does not exist. [4]
