Deformation analysis in central west Bulgaria using triangulation and GPS data

western United States ( Dong et al., 1998 ), central west Bulgaria ( Dimitrov and Georgiev, 2011 ), Central Valley, California ( Romero and Berber, 2018 ) and so on. Global Positioning System (GPS) data provide a good opportunity to study the current geodynamic processes, but the basic question arising in this case is how far the present-day results can be extrapolated back in time. An approach to address this question is to integrate GNSS with historical triangulation data in spite of the fact that the positional accuracy of the old triangulations is usually in the

Exploring the Meaning Problem of Big and Small Data Through Digital Method Triangulation

triangulation as a collective term to incorporate digital structuring, conditions and meanings of media studies of the onlife and demonstrates that the concept can be a valuable approach to methodological development in the field of social science and humanities. Digital method triangulation is proposed to be able to include combinations of qualitative and quantitative approaches of offline and online methods as well as of big and small data. Therefore, the two types of data-driven media studies used as examples – 1) digital focus groups and 2) measurements of internet

Altitude, Orthocenter of a Triangle and Triangulation

Summary

We introduce the altitudes of a triangle (the cevians perpendicular to the opposite sides). Using the generalized Ceva’s Theorem, we prove the existence and uniqueness of the orthocenter of a triangle [7]. Finally, we formalize in Mizar [1] some formulas [2] to calculate distance using triangulation.

Reconstructing Surface Triangulations by Their Intersection Matrices 26 September 2014

Abstract

The intersection matrix of a simplicial complex has entries equal to the rank of the intersecction of its facets. We prove that this matrix is enough to define up to isomorphism a triangulation of a surface.
