  2. Process identifier - Wikipedia

    en.wikipedia.org/wiki/Process_identifier

    The parent may, for example, wait for the child to terminate with the waitpid() function, or terminate the process with kill(). There are two tasks with specially distinguished process IDs: PID 0 is used for swapper or sched , which is part of the kernel and is a process that runs on a CPU core whenever that CPU core has nothing else to do.

  3. Proportional–integral–derivative controller - Wikipedia

    en.wikipedia.org/wiki/Proportional–integral...

    Another early example of a PID-type controller was developed by Elmer Sperry in 1911 for ship steering, though his work was intuitive rather than mathematically-based. [ 9 ] It was not until 1922, however, that a formal control law for what we now call PID or three-term control was first developed using theoretical analysis, by Russian American ...

  4. Principal ideal domain - Wikipedia

    en.wikipedia.org/wiki/Principal_ideal_domain

    An example of a principal ideal domain that is not a Euclidean domain is the ring [+], [6] [7] this was proved by Theodore Motzkin and was the first case known. [8] In this domain no q and r exist, with 0 ≤ | r | < 4 , so that ( 1 + − 19 ) = ( 4 ) q + r {\displaystyle (1+{\sqrt {-19}})=(4)q+r} , despite 1 + − 19 {\displaystyle 1+{\sqrt ...

  5. Program-specific information - Wikipedia

    en.wikipedia.org/wiki/Program-specific_information

    Each of the listed programs is identified by a 16-bit value called program_number. Each of the programs listed in PAT has an associated value of PID for its PMT. The value 0x0000 for program_number is reserved to specify the PID where to look for network information table. If such a program is not present in PAT the default PID value (0x0010 ...

  6. Persistent identifier - Wikipedia

    en.wikipedia.org/wiki/Persistent_identifier

    An introduction to persistent identifiers and FAIR data.. A persistent identifier (PI or PID) is a long-lasting reference to a document, file, web page, or other object.. The term "persistent identifier" is usually used in the context of digital objects that are accessible over the Internet.

  7. OBD-II PIDs - Wikipedia

    The exceptions are PID 01, which is only available in service 01, and PID 02, which is only available in service 02. If service 02 PID 02 returns zero, then there is no snapshot and all other service 02 data is meaningless. When using Bit-Encoded-Notation, quantities like C4 means bit 4 from data byte C.

  8. Personal identifier - Wikipedia

    en.wikipedia.org/wiki/Personal_identifier

    Personal Identifiers (PID) are a subset of personally identifiable information (PII) data elements, which identify an individual and can permit another person to "assume" that individual's identity without their knowledge or consent. [1] PIIs include direct identifiers (name, social security number) and indirect identifiers (race, ethnicity ...

  9. Unique factorization domain - Wikipedia

    en.wikipedia.org/wiki/Unique_factorization_domain

    In practice, (2) and (3) are the most useful conditions to check. For example, it follows immediately from (2) that a PID is a UFD, since every prime ideal is generated by a prime element in a PID. For another example, consider a Noetherian integral domain in which every height one prime ideal is principal.
