Ajuste Gaussiano de redes por el método de incrementos de coordenadas

Jiménez Martínez, Mª Jesús; Quesada Olmo, María Nieves; Villar Cano, Miriam; Paredes Asencio, Jose Manuel; Marqués Mateu, Ángel (Real Acadèmia de Cultura Valenciana, 2011-09-22)

[EN] We want to introduce a new way of performing the Gauss Markov adjustment of a micro geodetic net with ‘Coordinate increases’. It could be applied to angular and distance measurements, also to GNSS observations. We ...
An Approach to Improving GNSS Positioning Accuracy Using Several GNSS Devices

Jiménez-Martínez, Mª Jesús; Farjas-Abadia, Mercedes; Quesada-Olmo, María Nieves (MDPI AG, 2021-03)

[EN] Single point positioning (SPP) mode, related to pseudorange measurements, limits the level of accuracy to several meters in open sky and to several dozens of meters in urban canyons. This paper explores the effect of ...
Bridge Deformation Analysis Using Time-Differenced Carrier-Phase Technique

Jiménez-Martínez, Mª Jesús; Quesada-Olmo, María Nieves; Zancajo-Jimeno, José Julio; Mostaza-Pérez, Teresa (MDPI AG, 2023-03)

[EN] Historically, monitoring possible deformations in suspension bridges has been a crucial issue for structural engineers. Therefore, to understand and calibrate models of the "load-structureresponse", it is essential ...
Desarrollo y análisis de un sistema para la determinación de la dinámica del movimiento más general de la azotea de un edificio de gran altura y su evolución en el tiempo

Quesada Olmo, María Nieves (Universitat Politècnica de València, 2019-12-01)

[EN] The goal of this research is to analise and to develop a system that allows the determination of the most general movement dynamics of a tall building, as well as to quantify its evolution over time by means of Gaussian ...
Influence of rescanning mesh holes and stitching procedures on the complete-arch scanning accuracy of an intraoral scanner: An in vitro study

Gómez-Polo, Miguel; Piedra-Gascón, Wenceslao; Methani, Mohamed M.; Quesada-Olmo, María Nieves; Farjas-Abadia, Mercedes; Revilla-León, Marta (Elsevier, 2021-07)

[EN] Purpose: To measure the impact of different scanning patches on the accuracy (trueness and precision) of an intraoral scanner (IOS). Material and methods: A typodont was digitized using an industrial optical scanner ...
Influence of rescanning mesh holes on the accuracy of an intraoral scanner: An in vivo study

Revilla-León, Marta; Quesada-Olmo, María Nieves; Gómez-Polo, Miguel; Sicilia, Elena; Farjas-Abadia, Mercedes; Kois, John C (Elsevier, 2021-12)

[EN] Objectives: To evaluate whether the cutting-off and rescanning procedures have an impact on the accuracy (trueness and precision) of the intraoral digital scan. Methods: A right quadrant digital scan (reference scan) ...
Real-time high-rise building monitoring system using global navigation satellite system technology

Quesada Olmo, María Nieves; Jiménez-Martínez, Mª Jesús; Farjas Abadía, Mercedes (Elsevier, 2018)

[EN] Continuous assessment of the displacement of a high-rise building enables verification that it meets the structural assumptions calculated in the project, and provides additional useful feedback for structural engineers. ...
Scanning accuracy of nondental structured light extraoral scanners compared with that of a dental-specific scanner.

Piedra-Cascón, Wenceslao; Methani, Mohamed M.; Quesada-Olmo, María Nieves; Jiménez-Martínez, Mª Jesús; Revilla-León, Marta (Elsevier - Mosby, 2021-07)

[EN] Statement of problem. Diagnostic stone casts can be digitized by using dental optical scanners based on structured light scanning technology. Nondental structured light scanning scanners could also be used; however, ...
