  2. Infrastructure as code - Wikipedia

    en.wikipedia.org/wiki/Infrastructure_as_code

    Infrastructure as code ( IaC) is the process of managing and provisioning computer data center resources through machine-readable definition files, rather than physical hardware configuration or interactive configuration tools. [1] The IT infrastructure managed by this process comprises both physical equipment, such as bare-metal servers, as ...

  3. Dye-sensitized solar cell - Wikipedia

    en.wikipedia.org/wiki/Dye-sensitized_solar_cell

    Dye-sensitized solar cell. A selection of dye-sensitized solar cells. A dye-sensitized solar cell ( DSSC, DSC, DYSC [1] or Grätzel cell) is a low-cost solar cell belonging to the group of thin film solar cells. [2] It is based on a semiconductor formed between a photo-sensitized anode and an electrolyte, a photoelectrochemical system.

  4. Differential scanning calorimetry - Wikipedia

    en.wikipedia.org/wiki/Differential_scanning...

    Differential scanning calorimetry ( DSC) is a thermoanalytical technique in which the difference in the amount of heat required to increase the temperature of a sample and reference is measured as a function of temperature. [ 1] Both the sample and reference are maintained at nearly the same temperature throughout the experiment.

  7. Digital selective calling - Wikipedia

    en.wikipedia.org/wiki/Digital_Selective_Calling

    Digital selective calling. Digital selective calling ( DSC) is a standard for transmitting predefined digital messages via the medium-frequency (MF), high-frequency (HF) and very-high-frequency (VHF) maritime radio systems. It is a core part of the Global Maritime Distress Safety System (GMDSS). [1]

  8. Nastran - Wikipedia

    en.wikipedia.org/wiki/Nastran

    NASTRAN was designed from the beginning to consist of several modules. A module is a collection of FORTRAN subroutines designed to perform a specific task—processing model geometry, assembling matrices, applying constraints, solving matrix problems, calculating output quantities, conversing with the database, printing the solution, and so on.

  9. Display Stream Compression - Wikipedia

    en.wikipedia.org/wiki/Display_Stream_Compression

    Display Stream Compression ( DSC) is a VESA -developed video compression algorithm designed to enable increased display resolutions and frame rates over existing physical interfaces, and make devices smaller and lighter, with longer battery life. [1] It is a low-latency algorithm based on delta PCM coding and YC G C O -R color space.
