  2. Spacetime - Wikipedia

    en.wikipedia.org/wiki/Spacetime

    In physics, spacetime, also called the space-time continuum, is a mathematical model that fuses the three dimensions of space and the one dimension of time into a single four-dimensional continuum. Spacetime diagrams are useful in visualizing and understanding relativistic effects, such as how different observers perceive where and when events ...

  3. Space–time block code - Wikipedia

    en.wikipedia.org/wiki/Space–time_block_code

    Space–time block coding is a technique used in wireless communications to transmit multiple copies of a data stream across a number of antennas and to exploit the various received versions of the data to improve the reliability of data transfer.

  4. Semantic spacetime - Wikipedia

    en.wikipedia.org/wiki/Semantic_spacetime

    Semantic Spacetime was introduced by physicist and computer scientist Mark Burgess, in a series of papers called Spacetimes with Semantics, [1] [2] [3] as a practical alternative to describing space and time, initially for Computer Science. It attempts to unify both quantitative and qualitative aspects of spacetime processes into a single model.

  5. Computer network - Wikipedia

    en.wikipedia.org/wiki/Computer_network

    An internetwork is the connection of multiple different types of computer networks to form a single computer network using higher-layer network protocols and connecting them together using routers. The Internet is the largest example of internetwork. It is a global system of interconnected governmental, academic, corporate, public, and private ...

  6. Space–time code - Wikipedia

    en.wikipedia.org/wiki/Space–time_code

    A space–time code (STC) is a method employed to improve the reliability of data transmission in wireless communication systems using multiple transmit antennas. STCs rely on transmitting multiple, redundant copies of a data stream to the receiver in the hope that at least some of them may survive the physical path between transmission and ...

  7. List of spacetimes - Wikipedia

    en.wikipedia.org/wiki/List_of_spacetimes

    On certain regions of spacetime (and possibly the entire spacetime) one can describe the points by a set of coordinates. In this case, the metric can be written down in terms of the coordinates, or more precisely, the coordinate one-forms and coordinates.

  8. Mark Burgess (computer scientist) - Wikipedia

    en.wikipedia.org/wiki/Mark_Burgess_(computer...

    Semantic Spacetime was introduced by Mark Burgess, in a series of papers, [25] [26] [27] as an alternative to describing space and time, initially for Computer Science, after finding earlier models by Milner and others to be wanting. [28] [29] It attempts to unify both quantitative and qualitative aspects of spacetime processes into a single ...

  9. Space–time tradeoff - Wikipedia

    en.wikipedia.org/wiki/Space–time_tradeoff

    A space–time trade off can be applied to the problem of data storage. If data is stored uncompressed, it takes more space but access takes less time than if the data were stored compressed (since compressing the data reduces the amount of space it takes, but it takes time to run the decompression algorithm). Depending on the particular ...
