  2. Document Content Architecture - Wikipedia

    en.wikipedia.org/wiki/Document_Content_Architecture

    Document Content Architecture, or DCA for short, is a standard developed by IBM for text documents in the early 1980s. DCA was used on mainframe and IBM i systems and formed the basis of DisplayWrite's file format. DCA was later extended as MO:DCA (Mixed Object Document Content Architecture), which added embedded data files.

  3. Advanced Function Presentation - Wikipedia

    en.wikipedia.org/wiki/Advanced_Function_Presentation

    A MO:DCA file consists of a sequential, ordered hierarchy of independent objects - documents, pages, data objects, and resource objects such as fonts and ICC profiles. Each object is delimited by begin/end structures, and objects to be rendered specify presentation parameters and resource requirements in structures called "environment groups".

  5. C dynamic memory allocation - Wikipedia

    en.wikipedia.org/wiki/C_dynamic_memory_allocation

    The C programming language manages memory statically, automatically, or dynamically.Static-duration variables are allocated in main memory, usually along with the executable code of the program, and persist for the lifetime of the program; automatic-duration variables are allocated on the stack and come and go as functions are called and return.

  6. Deterministic finite automaton - Wikipedia

    en.wikipedia.org/wiki/Deterministic_finite_automaton

    An example of a deterministic finite automaton that accepts only binary numbers that are multiples of 3. The state S 0 is both the start state and an accept state. For example, the string "1001" leads to the state sequence S 0, S 1, S 2, S 1, S 0, and is hence accepted.

    This image or file is a work of a Federal Aviation Administration employee, taken or made as part of that person's official duties. As a work of the U.S. federal government , the image is in the public domain in the United States.

  8. Discrete Fourier series - Wikipedia

    en.wikipedia.org/wiki/Discrete_Fourier_series

    The result of the series is also a function of the discrete variable, i.e. a discrete sequence. A Fourier series, by nature, has a discrete set of components with a discrete set of coefficients, also a discrete sequence. So a DFS is a representation of one sequence in terms of another sequence.

  9. Channel allocation schemes - Wikipedia

    en.wikipedia.org/wiki/Channel_allocation_schemes

    In Fixed Channel Allocation or Fixed Channel Assignment (FCA) each cell is given a predetermined set of frequency channels. FCA requires manual frequency planning, which is an arduous task in time-division multiple access (TDMA) and frequency-division multiple access (FDMA) based systems since such systems are highly sensitive to co-channel interference from nearby cells that are reusing the ...
