  2. Pushback (migration) - Wikipedia

    en.wikipedia.org/wiki/Pushback_(migration)

    Neža Kogovšek Šalamon considers that there is no single, recognized definition of a pushback, but in general they can be characterized as "informal collective forced returns of people who irregularly enter the country back to the country they entered from, via procedures that take place outside legally defined rules in protocols or agreements signed by the neighbouring countries".

  4. Pushforward measure - Wikipedia

    en.wikipedia.org/wiki/Pushforward_measure

    In general, any measurable function can be pushed forward. The push-forward then becomes a linear operator, known as the transfer operator or Frobenius–Perron operator.In finite spaces this operator typically satisfies the requirements of the Frobenius–Perron theorem, and the maximal eigenvalue of the operator corresponds to the invariant measure.

  5. Document management system - Wikipedia

    en.wikipedia.org/wiki/Document_management_system

    While many electronic document management systems store documents in their native file format (Microsoft Word or Excel, PDF), some web-based document management systems are beginning to store content in the form of HTML. These HTML-based document management systems can act as publishing systems or policy management systems. [1]

  6. Non-refoulement - Wikipedia

    en.wikipedia.org/wiki/Non-refoulement

    Non-refoulement (/ r ə ˈ f uː l m ɒ̃ /) is a fundamental principle of international law anchored in the Convention Relating to the Status of Refugees that forbids a country from deporting ("refoulement") any person to any country in which their "life or freedom would be threatened" on account of "race, religion, nationality, membership of a particular social group or political opinion".

  7. Pushforward (differential) - Wikipedia

    en.wikipedia.org/wiki/Pushforward_(differential)

    For example, if the map φ is not surjective, there is no natural way to define such a pushforward outside of the image of φ. Also, if φ is not injective there may be more than one choice of pushforward at a given point. Nevertheless, one can make this difficulty precise, using the notion of a vector field along a map.

  8. Data conversion - Wikipedia

    en.wikipedia.org/wiki/Data_conversion

    PDF does not know of a word space character—the space between two letters and the space between two words differ only in quantity. Therefore, a title with ample letter-spacing for effect will usually end up with spaces in the word processor file, for example INTRODUCTION with spacing of 1 em as I N T R O D U C T I O N on the word processor.

  9. Progress, plans, problems - Wikipedia

    en.wikipedia.org/wiki/Progress,_plans,_problems

    Progress, plans, problems (PPP) is a management technique for recurring (daily, weekly or monthly) status reporting. A person reports 3-5 achievements, goals and challenges from the reporting period.
