  3. Digital selective calling - Wikipedia

    en.wikipedia.org/wiki/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).

  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.

  11. Data Coding Scheme - Wikipedia

    en.wikipedia.org/wiki/Data_Coding_Scheme

    Data Coding Scheme is a one- octet field in Short Messages (SM) and Cell Broadcast Messages (CB) which carries a basic information how the recipient handset should process the received message. The information includes: the character set or message coding, which determines the encoding of the message user data.
