WebTriangulation is a term in psychology most closely associated with the work of Murray Bowen known as family therapy. Bowen theorized that a two-person emotional system is unstable, in that under stress it forms itself into a three-person system or triangle. Family theory. In the family triangulation system, the third person can either be used ...

WebEn mathématiques et plus particulièrement en géométrie algorithmique, la triangulation de Delaunay d'un ensemble P de points du plan est une triangulation DT(P) telle qu'aucun point de P n'est à l'intérieur du cercle circonscrit d'un des triangles de DT(P).Les triangulations de Delaunay maximisent le plus petit angle de l'ensemble des angles des …

WebEn géométrie et trigonométrie, la triangulation est une technique permettant de déterminer la position d'un point en mesurant les angles entre ce point et d'autres points de référence dont la position est connue, et ceci plutôt que de mesurer directement la distance entre les points. Ce point peut être considéré comme étant le troisième sommet d'un triangle dont …

WebLet n be the number of points and d the number of dimensions.. The union of all simplices in the triangulation is the convex hull of the points. The Delaunay triangulation contains O(n ⌈d / 2⌉) simplices.; In the plane (d = 2), if there are b vertices on the convex hull, then any triangulation of the points has at most 2n − 2 − b triangles, plus one exterior face (see …

WebTriangulation today is used for many purposes, including surveying, navigation, metrology, astrometry, binocular vision, model rocketry and, in the military, the gun direction, the trajectory and distribution of fire power of weapons. The use of triangles to estimate distances dates to antiquity.

WebProperties. The dual graph for a Voronoi diagram (in the case of a Euclidean space with point sites) corresponds to the Delaunay triangulation for the same set of points.; The closest pair of points corresponds to two adjacent cells in the Voronoi diagram.; Assume the setting is the Euclidean plane and a discrete set of points is given. Then two points of …

WebIn the social sciences, triangulation refers to the application and combination of several research methods in the study of the same phenomenon. By combining multiple observers, theories, methods, and empirical materials, researchers hope to overcome the weakness or intrinsic biases and the problems that come from single method, single-observer, and …

WebThe Polish mathematician Kazimierz Kuratowski provided a characterization of planar graphs in terms of forbidden graphs, now known as Kuratowski's theorem: . A finite graph is planar if and only if it does not contain a subgraph that is a subdivision of the complete graph K 5 or the complete bipartite graph K 3,3 (utility graph).. A subdivision of a graph results …

WebIn surveying, triangulation is the process of determining the location of a point by measuring only angles to it from known points at either end of a fixed baseline by using trigonometry, rather than measuring distances to the point directly as in trilateration.The point can then be fixed as the third point of a triangle with one known side and two known …

WebTriangulation ist eine geometrische Methode der optischen Abstandsmessung durch genaue Winkelmessung innerhalb von Dreiecken. Die Berechnung erfolgt mittels trigonometrischer Funktionen.Vereinfacht könnte man auch sagen, dass von zwei Punkten, deren Abstand bekannt ist, Winkelmessungen zu beliebig anderen Punkten im Raum …
