Acceleration-based signal processing of esophageal ECG signals

Sánchez Martínez, Sergio (Universitat Politècnica de València, 2014-06-11)

[ES] Registro simultáneo de alta calidad de señales ECG esofágicas y acceleración. Dichas señales son usadas para cuantificar la actividad mecánica cardíaca y para implementar un filtro adaptativo capaz de eliminar la ...
Convex combination filtered-X algorithms for active noise control systems

Ferrer Contreras, Miguel; Gonzalez, Alberto; Diego Antón, María de; Piñero Sipán, María Gemma (Institute of Electrical and Electronics Engineers (IEEE), 2013-01)

Adaptive filtering schemes exhibit a compromise between convergence speed and steady-state mean square error. Trying to overcome this trade-off, convex combination of adaptive filters have been recently developed for system ...
Extracción de series temporales de ritmo cardíaco a partir de un sistema de fotopletismografía

Planells Palop, Carlos (Universitat Politècnica de València, 2018-10-17)

[ES] Este TFM propone, diseña y verifica el funcionamiento de un sistema para la obtención de la variabilidad cardiaca a partir de un sistema de fotopletismografía (PPG). Tras el análisis de los resultados obtenidos se ...
Filtrado Adaptativo de Componentes Involuntarias en Marcha Asistida por Andador para Detección de Intenciones

Frizera, A.; Ceres, R.; Pons, J. L. (Universitat Politècnica de València, 2011-04-08)

[EN] The advances in technology have allowed the use of sensors, processors and actuators in the context of the mobility assistive devices for disabled people, improving their usability and safety. Considering walkers, the ...
Fuzzy control for obstacle detection in stereo video sequences

Parrilla Bernabé, Eduardo; Torregrosa Sánchez, Juan Ramón; Riera Guasp, Jaime; Hueso Pagoaga, José Luís (Elsevier, 2011-10)

One of the most important problems in 3D tracking is the occlusion effect produced by obstacles. To solve this problem, we have developed a tracking system based on optical flow and stereo vision, combined with adaptive ...
Modelo de predicción de demanda de energía eléctrica mediante técnicas Set-Membership

Diaz, Jimena; Vuelvas, Jose; Ruiz, Fredy; Patiño, Diego (Universitat Politècnica de València, 2019-09-20)

[EN] This work presents a model for the short-term forecast of electric load, based on Set-Membership techniques. The model is formed by a periodic component and an adaptive non-linear autoregressive component. The ...
Novel technique for estimating pollution-associated leakage current in high voltage insulators based on adaptive filtering in long-term recording

Bueno-Barrachina, José-M.; Cañas Peñuelas, César Santiago; Ye Lin, Yiyao; Fuster Roig, Vicente Luis (IOP Publishing, 2021-05)

[EN] Moist polluting substances on high-voltage insulator surfaces can cause power-line failures by triggering electric arcs. There are at present no effective methods of measuring insulator pollution levels during normal ...
Selection of the convergence step of the Fx-LMS algorithm

Ferrer Contreras, Miguel; de Diego Antón, María; García Mollá, Víctor Manuel; Gonzalez, Alberto (Elsevier, 2023-10)

[EN] The choice of a suitable convergence step that allows the fast convergence of the filtered-x LMS algorithm in practical scenarios is usually carried out by trial and error, since the theoretical developments provide ...
Steady-state mean square performance of the multichannel filtered-X affine projection algorithm

Ferrer Contreras, Miguel; Diego Antón, María de; González Salvador, Alberto; Piñero Sipán, María Gemma (Institute of Electrical and Electronics Engineers (IEEE), 2012-06)

This paper provides a unified analysis of the steady-state behavior of different multichannel filtered-x affine projection algorithms when used in active noise control (ANC) systems. The analysis deals with two different ...
