This publication takes a distinct method of details retrieval through laying down the principles for a latest algebra of knowledge retrieval according to lattice thought. All significant retrieval tools built up to now are defined intimately – Boolean, Vector house and probabilistic tools, but additionally internet retrieval algorithms like PageRank, HITS, and SALSA – and the writer indicates that all of them might be handled elegantly in a unified formal means, utilizing lattice idea because the one simple notion.

13). By definition, the ideal transformer is a pair of inductively coupled circuits with zero'ohmic losses and unity coupling factor between Lx and £ 2 . Band C terms will reduce to the zero. 14) 39 ALGEBRA OF FOUR-TERMINAL NETWORKS The terms LJM and LJM are dimensionless ratios, they can be identified with the turns ratios \jn and n respectively. 15a) Ideal transformer (c) S E R I E S T U N E D INDUCTIVELY COUPLED CIRCUITS If one neglects to ohmic losses, a pair of series tuned coupled circuits may be represented as in Figs.

Reciprocal and Non-reciprocal Networks, Characterized by the Determinant of Matrix Earlier in Sections 3 and 6 it has been shown t h a t a fourterminal network is completely described by a parameter matrix. I t has been also demonstrated t h a t for passive networks the determinant of the transmission matrix is always unity. This mathematical relationship exists because the completely reciprocal or bilateral character of passive networks. That is, power loss is identical in both directions. On the other hand by definition in active - non-reciprocal networks the power gain or loss is different in forward and reverse directions.
