    Triangulation and Mixed Methods Research: Provocative Positions Article (PDF Available) in Journal of Mixed Methods Research 6(2) May with 1, Reads How we measure 'reads'. Multiparadigm approaches aid exploration of particularly complex and paradoxical phenomena by helping theorists employ disparate theoretical perspectives. In this article we provide an extensive guide to multiparadigm exemplars and then link their varied approaches within a metatriangulation theory-building strategy. Our process addresses the challenges theorists face as they select a research Cited by:

    Greene and colleagues have argued that this is precisely why mixed method designs are valuable, as divergent findings create an opportunity for "more insightful understanding," which can "lead to. Triangulation involves using multiple data sources in an investigation to produce understanding. Some see triangulation as a method for corroborating findings and as a test for validity. This, however, is controversial. This assumes that a weakness in one method will be compensated for by another method, and that it is always possible to make.

    Triangulation In social science triangulation is defined as the mixing of data or methods so that diverse viewpoints or standpoints cast light upon a topic. The mixing of data types, known as data triangulation, is often thought to help in validating the claims that might arise from an initial pilot study. The Use of Triangulation Methods in Qualitative Educational Research Triangulation involves the carejit! reviewing of data collected through different meth-ods in order to achieve a more accurate and valid estimate of qualitative results for a particular construct. This paper describes how we used three qualitative methods.

The U.S. Coast and Geodetic Survey has had an analytic system of aerotriangulation in routine production since Last year, the Bureau began the rewriting of its computer programs for analytic aerotriangulation in order to increase their efficiency and eliminate the need for human intervention during the computing by: 1.

Aerotriangulation and/or Ground Control Aerotriangulation is the process of assigning ground control values to points on a block of photographs by determining the relationship between the photographs and known ground control points.

The overlapping portions of adjacent photos are registered to one another using "pass points" on the photos. Known object recognition is the task of recognizing specific objects, such as cereal boxes or soda cans. Millions of such objects exist, and finding a computationally feasible method for recognition can be difficult.

Ideally, the computational costs should scale with the complexity of the testing image, and not the size of the object by: Aerotriangulation a method of determining the coordinates of points of a terrain on the basis of aerial photographs.

The purpose of aerotriangulation is to make a geodetic network more dense in order to provide photographs with the control points that are necessary for the compilation of topographic maps and for the solution of various engineering. Net, for constructing phylogenetic networks from a set of triplets.

Indeed, TripNet is an algorithm which given an ar-bitrary (not necessarily dense) set of triplets as input, out-puts an adequate phylogenetic network.

Although, due to the importance and the inherent dif-ficulty of the problem of reconstructing phylogenetic net. usefulness of GPS for their particular interests (e.g., aerotriangulation).

There are four main areas in photogrammetry where GPS can be used (Ackermann, ): 1- Establishment of ground control points using terrestrial GPS, 2- GPS controlled survey flight navigation, 3- High precision camera positioning for aerial triangulation,File Size: KB.

Aerotriangulation process can be applied using different techniques, such as analogue, semianalytical, analytical and of course digital techniques. Analytical aerotriangulation tends to be more accurate than analogue or semi analytical aerotriangulation, largely because analytic.

(1) Aerotriangulation using a mechanical, optical, or optomechanical model of the relationship between image point and object point. Two principal methods are used: the radial method, which obtains only the horizontal coordinates of the ground points; and stereotriangulation, which uses a stereoscopic plotting instrument to obtain horizontal coordinates, vertical coordinates or both.

To do it with arrays you would define an Array of Arrays, such as: int[][] a = {{1,2,3},{3,4,5},{5,6,7}}; If you triplets represent some kind of object in your application, for a more object orientated approach, it might make sense to create a Class to hold your triplets, and then store them in a list.

A central theme of the book is the use of the rich structure of the space of triangulations to solve computational problems (e.g., counting the number of triangulations or finding optimal triangulations with respect to various criteria), and to establish connections to applications in algebra, computer science, combinatorics, and optimization.
