  2. Scattering parameters - Wikipedia

    en.wikipedia.org/wiki/Scattering_parameters

    The S-parameter for a 1-port network is given by a simple 1 × 1 matrix of the form () where n is the allocated port number. To comply with the S-parameter definition of linearity, this would normally be a passive load of some type.

    SDG 11 addresses slums, human settlement management and planning, climate change mitigation and adaptation, and urban economies. Prior to the adoption of the 2030 Agenda, Millennium Development Goal 7, target 4, called for efforts to achieve a "significant improvement in the lives of at least 100 million slum dwellers" by 2020.

    EPSG Geodetic Parameter Dataset (also EPSG registry) is a public registry of geodetic datums, spatial reference systems, Earth ellipsoids, coordinate transformations and related units of measurement, originated by a member of the European Petroleum Survey Group (EPSG) in 1985.

  6. Signal integrity - Wikipedia

    en.wikipedia.org/wiki/Signal_integrity

    For example, IEEE P802.3ap Task Force uses measured S-parameters as test cases [11] for proposed solutions to the problem of 10 Gbit/s Ethernet over backplanes. Accurate noise modeling is a must. Create a list of expected noise events, including different types of noise, such as coupling and charge sharing .

  7. Impedance parameters - Wikipedia

    en.wikipedia.org/wiki/Impedance_parameters

    A Z-parameter matrix describes the behaviour of any linear electrical network that can be regarded as a black box with a number of ports.A port in this context is a pair of electrical terminals carrying equal and opposite currents into and out-of the network, and having a particular voltage between them.

  8. Dimensionless numbers in fluid mechanics - Wikipedia

    en.wikipedia.org/wiki/Dimensionless_numbers_in...

    Dimensionless numbers (or characteristic numbers) have an important role in analyzing the behavior of fluids and their flow as well as in other transport phenomena. [1] They include the Reynolds and the Mach numbers, which describe as ratios the relative magnitude of fluid and physical system characteristics, such as density, viscosity, speed of sound, and flow speed.

  9. Software design description - Wikipedia

    en.wikipedia.org/wiki/Software_Design_Description

    A software design description (a.k.a. software design document or SDD; just design document; also Software Design Specification) is a representation of a software design that is to be used for recording design information, addressing various design concerns, and communicating that information to the design’s stakeholders.
