  2. Method of moments (electromagnetics) - Wikipedia

    en.wikipedia.org/wiki/Method_of_moments...

    The method of moments (MoM), also known as the moment method and method of weighted residuals, [1] is a numerical method in computational electromagnetics. It is used in computer programs that simulate the interaction of electromagnetic fields such as radio waves with matter, for example antenna simulation programs like NEC that calculate the ...

    The mother and wife is responsible for all household services around the house. [56] According to Wilson, the married mother's tasks around the house is described as a full-time job. This full-time job of household responsibilities is often the second job that an African-American woman takes on. [57]

    However, for many problems, MoM are significantly computationally less efficient than volume-discretization methods (finite element method, finite difference method, finite volume method). Boundary element formulations typically give rise to fully populated matrices.

    (ii) In the context of nucleotide changes in DNA sequences, transition is a specific term for the exchange between either the two purines (A ↔ G) or the two pyrimidines (C ↔ T) (for additional details, see the article about transitions in genetics). By contrast, an exchange between one purine and one pyrimidine is called a transversion.

    en.wikipedia.org/wiki/Breadwinner_model

    The breadwinner model is a paradigm of family centered on a breadwinner, "the member of a family who earns the money to support the others." [1] Traditionally, the earner works outside the home to provide the family with income and benefits such as health insurance, while the non-earner stays at home and takes care of children and the elderly.

    The aim of such techniques as ANCOVA is to remove the effects of such uncontrolled variation, in order to increase statistical power and to ensure an accurate measurement of the true relationship between independent and dependent variables. [8] An example is provided by the analysis of trend in sea-level by Woodworth (1987). [9]

    The M1942 helmet (Also known as the “Modelo Z” and simply M42) is a military steel combat helmet used by Spain from its adoption in 1942 to its replacement by a Spanish M1 copy in the 1980s. [ 1 ]
