Minimum Cardinality Point-to-point Connectivity Augmentation Problem

open access: closedFundamenta Informaticae, 2018
We consider an augmentation problem to establish point-to-point connectivity on unweighted graphs where there is no restriction on choosing the augmenting edges (arcs). Given a directed (an undirected) graph G and set P = {( si, ti) : 1 ≤ i ≤ m} of pairs of vertices in the graph, one has to find the minimum cardinality set of arcs (edges) to be added ...

Cardinal ligament surgical anatomy: cardinal points at hysterectomy

International Urogynecology Journal, 2013
The cardinal ligament (CL) still requires more precise anatomical mapping. We aim to elucidate the anatomy of the CL and the roles it plays in gynecological surgery.Studies employed sharp dissection of 28 formalin-fixed cadaveric hemipelves and 10 unembalmed cadaveric hemipelves.The CL (total length averaging 10.0 cm) can be subdivided into three ...

Cardinal and anti‐cardinal points, equalities and chromatic dependence

Ophthalmic and Physiological Optics, 2017
AbstractPurposeCardinal points are used for ray tracing through Gaussian systems. Anti‐principal and anti‐nodal points (which we shall refer to as the anti‐cardinal points), along with the six familiar cardinal points, belong to a much larger set of special points.

CARDINAL POINTS IN APHAKIA

Archives of Ophthalmology, 1947
IN TWO previous communications 1 it was shown how the location and displacement of the cardinal points of the eye can be visualized and remembered by the use of the benzene ring. It was shown that when the eye accommodates the new position of the cardinal points can be represented by a long, slender ring situated inside the regular ring.
