orthogonal system

[ȯr′thäg·ən·əl ′sis·təm]
(mathematics)
A system made up of n families of curves on an n-dimensional manifold in an n + l dimensional euclidean space, such that exactly one curve from each family passes through every point in the manifold, and, at each point, the tangents to the n curves that pass through that point are mutually perpendicular.
A set of real-valued functions, the inner products of any two of which vanish. Also known as orthogonal family.

Since the width of the orthogonal structure is 15mm, the characteristic impedance of the entire orthogonal system is 41.7m[OMEGA], that is, the paralleled characteristic impedance of 45 transmission lines, each of 1.88[OMEGA].
Thus, we have an orthogonal system by the Gramm-Schmidt method:

Just as the convexity of the hall plays against the orthogonal system dominating the building, so the sloping plane of the ground floor (which extends the sloping paving of Schubert-Platz), plays against the strong horizontals of the building's section.
Schaefer (1974:169) defined an orthogonal set S of nonzero positive elements in a Banach lattice E to be a topological orthogonal system (t.o.s.) of E if the ideal generated by S is dense in E.
