In the social sciences, triangulation refers to the application and combination of several research methods in the study of the same phenomenon. [1] 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 single-theory studies.
Illustration from an edition of 1726 Gemma Frisius's 1533 proposal to use triangulation for mapmaking Nineteenth-century triangulation network for the triangulation of Rhineland-Hesse. Triangulation today is used for many purposes, including surveying, navigation, metrology, astrometry, binocular vision, model rocketry and gun direction of weapons.
Triangulation 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.
For example, smoothing (also referred to as mesh refinement) is one such method, which repositions nodes to minimize element distortion. The stretched grid method allows the generation of pseudo-regular meshes that meet the Delaunay criteria easily and quickly in a one-step solution.
Some methods result in a which is a closed-form continuous function while others need to be decomposed into a series of computational steps involving, for example, SVD or finding the roots of a polynomial. Yet another class of methods results in which must rely on iterative estimation of some parameters. This means that both the computation ...
Triangulation is a term in psychology most closely associated with the work of Murray Bowen known as family therapy. [ unreliable source? ] Bowen theorized that a two-person emotional system is unstable, in that under stress it forms itself into a three-person system or triangle.
A conceptual diagram illustrating political triangulation. In politics, triangulation is a strategy associated with U.S. President Bill Clinton in the 1990s. The politician presents a position as being above or between the left and right sides or wings of a democratic political spectrum. It involves adopting for oneself some of the ideas of one ...
Triangulation is a tactic used in chess to put one's opponent in zugzwang (a position in which it is a disadvantage to move). Triangulation is also called losing a tempo or losing a move .
