vertex

the vertex of a mountain.

the vertex of an arch

Now we need a vertex buffer.

First, the vertexes are sequenced according to their curvature to form a descending order vertex array.The rearer vertex has smaller local curvature.

Methods：Explain the difference between power and vertex power from basic definitions of optics, and analyze the measuring principle and error of focimeter.

The main causes of dystocia of vertex presentation were occiput malpresentation, macrosomic infant, uterine atony, abnormal pelvic and genital tract.

In this paper, we study the minimum-weight feedback vertex set problem in outerplanar graphs and present a linear time algorithm to solve it.

A pebbling move on a graph G consists of taking two pebbles off from a vertex and placing one pebble on an adjacent vertex.

Method 98 pregnant women with single pregnant、vertex present were randomized into mifepristone combined with oxytoxin group (A group) and oxytoxin group (B group).

Objective：To confirm that the lensometer adjusted by the special lenses group for contact lenses cant express the back vertex power of contact lenses.

This paper gives a vertex sequencing algorithm about complete oriented multigraph. Based on this algorithm, a useful optimum statistical pattern for documents selecting is described.
