  2. Medical Subject Headings - Wikipedia

    en.wikipedia.org/wiki/Medical_Subject_Headings

    When we search for a MeSH term, the most specific MeSH terms are automatically included in the search. This is known as the extended search or explode of that MeSH term. This additional information and the hierarchical structure (see below) make the MeSH essentially a thesaurus, rather than a plain subject headings list. [4]

  3. Datasheet - Wikipedia

    en.wikipedia.org/wiki/Datasheet

    Front page of a floppy disk controller data sheet (1979) A datasheet, data sheet, or spec sheet is a document that summarizes the performance and other characteristics of a product, machine, component (e.g., an electronic component), material, subsystem (e.g., a power supply), or software in sufficient detail that allows a buyer to understand what the product is and a design engineer to ...

    en.wikipedia.org/wiki/Difluoromethane

    [2] [failed verification] In the United States, the Clean Air Act Section 111 on Volatile Organic Compounds (VOC) has listed difluoromethane as an exception (since 1997) from the definition of VOC due to its low production of tropospheric ozone. [3] Difluoromethane is commonly used in endothermic processes such as refrigeration or air conditioning.

    An example SDS, including guidance for handling a hazardous substance and information on its composition and properties. A safety data sheet (SDS), [1] material safety data sheet (MSDS), or product safety data sheet (PSDS) is a document that lists information relating to occupational safety and health for the use of various substances and products.

  6. Mesh networking - Wikipedia

    en.wikipedia.org/wiki/Mesh_networking

    A mesh network is a local area network topology in which the infrastructure nodes (i.e. bridges, switches, and other infrastructure devices) connect directly, dynamically and non-hierarchically to as many other nodes as possible and cooperate with one another to efficiently route data to and from clients.

  7. Types of mesh - Wikipedia

    en.wikipedia.org/wiki/Types_of_mesh

    A coarse mesh may provide an accurate solution if the solution is a constant, so the precision depends on the particular problem instance. One can selectively refine the mesh in areas where the solution gradients are high, thus increasing fidelity there. Accuracy, including interpolated values within an element, depends on the element type and ...

  8. Reference data - Wikipedia

    en.wikipedia.org/wiki/Reference_data

    A further difference between reference data and master data is that a change to the reference data values may require an associated change in business process to support the change, while a change in master data will always be managed as part of existing business processes. For example, adding a new customer or sales product is part of the ...

  9. Reference designator - Wikipedia

    en.wikipedia.org/wiki/Reference_designator

    IEEE 200-1975 or "Standard Reference Designations for Electrical and Electronics Parts and Equipments" is a standard that was used to define referencing naming systems for collections of electronic equipment. IEEE 200 was ratified in 1975. The IEEE renewed the standard in the 1990s, but withdrew it from active support shortly thereafter.
