  2. Incremental encoder - Wikipedia

    en.wikipedia.org/wiki/Incremental_encoder

    Rotary incremental encoder with shaft attached to its thru-bore opening Introduction to incremental encoders, from VideoWiki script Incremental Encoder. An incremental encoder is a linear or rotary electromechanical device that has two output signals, A and B, which issue pulses when the device is moved. [1]

  3. Incremental encoding - Wikipedia

    en.wikipedia.org/wiki/Incremental_encoding

    Incremental encoding is widely used in information retrieval to compress the lexicons used in search indexes; these list all the words found in all the documents and a pointer for each one to a list of locations. Typically, it compresses these indexes by about 40%.

  4. Meta refresh - Wikipedia

    en.wikipedia.org/wiki/Meta_refresh

    Meta refresh is a method of instructing a web browser to automatically refresh the current web page or frame after a given time interval, using an HTML meta element with the http-equiv parameter set to "refresh" and a content parameter giving the time interval in seconds.

  5. Rolling hash - Wikipedia

    en.wikipedia.org/wiki/Rolling_hash

    A rolling hash (also known as recursive hashing or rolling checksum) is a hash function where the input is hashed in a window that moves through the input.. A few hash functions allow a rolling hash to be computed very quickly—the new hash value is rapidly calculated given only the old hash value, the old value removed from the window, and the new value added to the window—similar to the ...

  6. Incremental computing - Wikipedia

    en.wikipedia.org/wiki/Incremental_computing

    When incremental computing is implemented by a tool that can implement it for a variety of different pieces of code automatically, that tool is an example of a program analysis tool for optimization. Incremental computing derives a new input/output pair from one or more old input/output relationships.

  7. Fold (higher-order function) - Wikipedia

    en.wikipedia.org/wiki/Fold_(higher-order_function)

    The use of an initial value is necessary when the combining function f is asymmetrical in its types (e.g. a → b → b), i.e. when the type of its result is different from the type of the list's elements. Then an initial value must be used, with the same type as that of f 's result, for a linear chain of applications to be possible. Whether it ...

  8. Tracing garbage collection - Wikipedia

    en.wikipedia.org/wiki/Tracing_garbage_collection

    Incremental and concurrent garbage collectors are designed to reduce this disruption by interleaving their work with activity from the main program. Incremental garbage collectors perform the garbage collection cycle in discrete phases, with program execution permitted between each phase (and sometimes during some phases).

  9. Memory refresh - Wikipedia

    en.wikipedia.org/wiki/Memory_refresh

    For example, DDR SDRAM has a refresh time of 64 ms and 8,192 rows, so the refresh cycle interval is 7.8 μs. [5] [9] Generations of DRAM chips developed after 2012 contain an integral refresh counter, and the memory control circuitry can either use this counter or provide a row address from an external counter.
