Values shown above are approximate and valid only at the magnetic fields shown. They are given for a zero frequency; in practice, the permeability is generally a function of the frequency. When the frequency is considered, the permeability can be complex , corresponding to the in-phase and out of phase response.
The best known [1] general exact algorithm is due to H. J. Ryser ().Ryser's method is based on an inclusion–exclusion formula that can be given [2] as follows: Let be obtained from A by deleting k columns, let () be the product of the row-sums of , and let be the sum of the values of () over all possible .
The permanents corresponding to the smallest projective planes have been calculated. For n = 2, 3, and 4 the values are 24, 3852 and 18,534,400 respectively. [13] Let Z be the incidence matrix of the projective plane with n = 2, the Fano plane. Remarkably, perm(Z) = 24 = |det (Z)|, the absolute value of the determinant of Z.
Symbol used to represent in situ permeability tests in geotechnical drawings. In fluid mechanics, materials science and Earth sciences, the permeability of porous media (often, a rock or soil) is a measure of the ability for fluids (gas or liquid) to flow through the media; it is commonly symbolized as k.
Index l = 3, because 4 is the only value in the sequence that is greater than 3 in order to satisfy the condition a[k] < a[l]. The values of a[2] and a[3] are swapped to form the new sequence [1, 2, 4, 3]. The sequence after k-index a[2] to the final element is reversed. Because only one value lies after this index (the 3), the sequence remains ...
In a reference amount of 100 grams (3 + 1 ⁄ 2 ounces), raw green peas supply 339 kilojoules (81 kilocalories) of food energy, and are a rich source (20% or more of the Daily Value, DV) of vitamin C (48% DV), vitamin K, thiamine, and manganese, with several B vitamins and dietary minerals in moderate amounts (11–16% DV).
Many Malay loanwords entered the Tagalog vocabulary during pre-colonial times as Old Malay became the lingua franca of trade, commerce and diplomatic relations during the pre-colonial era of Philippine history as evidenced by the Laguna Copperplate Inscription of 900 AD and accounts of Antonio Pigafetta at the time of the Spanish arrival in the ...
