tri·an·gu·la·tion

(trī-ăng′gyə-lā′shən)

a. A surveying technique in which a region is divided into a series of triangular elements based on a line of known length so that accurate measurements of distances and directions may be made by the application of trigonometry.

b. The network of triangles so laid out.

2. The location of an unknown point, as in navigation, by the formation of a triangle having the unknown point and two known points as the vertices.

3. The establishment of a political position that differs from two existing or opposing positions, especially in being moderate.

triangulation

(traɪˌæŋɡjʊˈleɪʃən)

1. (Surveying) a method of surveying in which an area is divided into triangles, one side (the base line) and all angles of which are measured and the lengths of the other lines calculated trigonometrically

2. (Surveying) the network of triangles so formed

3. (Navigation) the fixing of an unknown point, as in navigation, by making it one vertex of a triangle, the other two being known

4. (Chess & Draughts) chess a key manoeuvre in the endgame in which the king moves thrice in a triangular path to leave the opposing king with the move and at a disadvantage

tri•an•gu•la•tion

(traɪˌæŋ gyəˈleɪ ʃən)

n.

1. a technique for establishing the distance between any two points, or the relative position of two or more points, by calculations based on the vertices of a triangle and the length of side of measurable length (base or baseline).

2. the triangles thus formed and measured.

tri·an·gu·la·tion

(trī-ăng′gyə-lā′shən)

1. A method used to determine distances and directions of a region of land. The region is divided into a set of triangles based on a line of known length. The triangles are then measured using trigonometry.

2. A method of determining the location of a boat or aircraft by means of trigonometry.

	2.	triangulation - a method of surveying; the area is divided into triangles and the length of one side and its angles with the other two are measured, then the lengths of the other sides can be calculated surveying - the practice of measuring angles and distances on the ground so that they can be accurately plotted on a map; "he studied surveying at college"

In order to assess the spatial uniformity of the particles, we propose in this study to process the TRISO particles in a 3-dimensional (3D) coordinate system and assess the uniformity of the TRISO particle distribution using the geometric metrics extracted from the Voronoi tessellation and Delaunay triangulation. The number of particles and their locations were obtained by the use of an image-processing method, after a cone-beam computed tomography (CBCT) was used for data acquisition.
