A robust wavelet-based approach for dominant frequency analysis of atrial fibrillation in body surface signals

Marques, V.G.; RODRIGO BORT, MIGUEL; Guillem Sánchez, María Salud; Salinet, J. (IOP Publishing, 2020-07)

[EN] Objective: Atrial dominant frequency (DF) maps undergoing atrial fibrillation (AF) presented good spatial correlation with those obtained with the non-invasive body surface potential mapping (BSPM). In this study, a ...
Active concentric ring electrode for non-invasive detection of intestinal myoelectric signals

Prats Boluda, Gema; Garcia Casado, Francisco Javier; Martínez De Juan, José Luís; Ye Lin, Yiyao (Elsevier, 2011-05)

[EN] Although the surface electroenterogram (EEnG) is a weak signal contaminated by strong physiological interference, such as ECG and respiration, abdominal surface recordings of the EEnG could provide a non-invasive ...
Characterization of atrial arrhythmias in body surface potential mapping: A computational study

Gonçalves Marques, Victor; RODRIGO BORT, MIGUEL; Guillem Sánchez, María Salud; Salinet, Joao (Elsevier, 2020-12)

[EN] Purpose: Atrial tachycardia (AT), flutter (AFL) and fibrillation (AF) are very common cardiac arrhythmias and are driven by localized sources that can be ablation targets. Non-invasive body surface potential mapping ...
Diseño de un biosensor óptico de glucosa basado en una red de difracción 3D

Dumitrascu, Carla Teodora (Universitat Politècnica de València, 2019-07-31)

[ES] Este Trabajo Final de Grado aborda el diseño de un biosensor óptico para la detección de glucosa destinado a ser integrado en una lentilla oftalmológica. Este dispositivo permite la monitorización de los parámetros ...
Estudio y correlación de la sintomatología y el efecto del tratamiento por ultrasonido del temblor esencial a través de escalas estandarizadas e imagen médica

Farnham Torrelles, Carla (Universitat Politècnica de València, 2022-09-07)

[ES] El trabajo de fin de grado propuesto se basa en el análisis del tratamiento por MRgFUS de pacientes con temblor esencial. Esta técnica guiada por resonancia magnética de ultrasonidos de alta intensidad permite una ...
Infrared spectroscopy and chemometric applications for the qualitative and quantitastive investigation of grapevine organs.

Wyngaard, Elizma van; Blancquaert, Erna; Nieuwouldt, Helene; Aleixandre Tudo, José (Frontiers Media SA, 2021-09-03)

[EN] The fourth agricultural revolution is leading us into a time of using data science as a tool to implement precision viticulture. Infrared spectroscopy provides the means for rapid and large-scale data collection to ...
Multiband Photogrammetry and Hybrid Image Analysis for the Investigation of a Wall Painting by Paolo de San Leocadio and Francesco Pagano in the Cathedral of Valencia

Rahrig, Max; Herrero-Cortell, Miguel Ángel; Lerma, José Luis (MDPI AG, 2023-02)

[EN] A workflow for the photogrammetric combination of non-invasive multispectral imaging techniques ranging from ultraviolet (UV) and visible (VIS) to near infrared (NIR) for the investigation of wall paintings is presented. ...
Non-invasive and continuous monitoring of the sol gel phase transition of supramolecular gels using a fast (open-ended coaxial) microwave sensor

Carrillo, Adela I.; Bachl, Jürgen; Mayr, Judith; Plaza González, Pedro José; Catalá Civera, José Manuel; Díaz Díaz, David (The Royal Society of Chemistry, 2015)

[EN] An open coaxial re-entrant microwave sensor has been used for the non-invasive and continuous monitoring of the sol-gel transition of physical gels characterized by different gelation mechanisms, solvents, compositions, ...
Non-invasive monitoring of potato drying by means of air-coupled ultrasound

Sanchez-Jimenez, Virginia; Collazos-Escobar, Gentil Andres; González-Mohino, Alberto; Gomez Alvarez-Arenas, Tomas E.; Benedito Fort, José Javier; Garcia-Perez, J.V. (Elsevier, 2023-06)

[EN] Air-coupled ultrasound could be considered a suitable on-line technique for the non-invasive industrial testing of potato products manufactured in slices such as dried, fried or baked potato chips. Thus, the aim of ...
Physical Wellbeing Monitoring Employing Non-Invasive Low-Cost and Low-Energy Sensor Socks

García-García, Laura; Parra-Boronat, Lorena; Jimenez, Jose M.; Lloret, Jaime (MDPI AG, 2018)

[EN] Determining and improving the wellbeing of people is one of the priorities of the OECD countries. Nowadays many sensors allow monitoring different parameters in regard to the wellbeing of people. These sensors can be ...
Use of air-coupled ultrasound for the non-invasive characterization of the textural properties of pork burger patties

Fernandez-Caballero-Fariñas, Maria Dolores; Contreras, Marina; Sanchez-Jimenez, Virginia; Benedito Fort, José Javier; Garcia-Perez, J.V. (Elsevier, 2021-05)

[EN] This study tests the feasibility of air-coupled ultrasound for the characterization of the textural properties of pork burger patties. The samples were prepared by mixing lard at different percentages (0, 20, 40, 60 ...
