A wireless Sensor Network that use Image Processing for Vineyard Monitoring

Lloret, Jaime; Bosch Roig, Ignacio; Sendra Compte, Sandra; Serrano Cartagena, Arturo (MDPI, 2011)

The first step to detect when a vineyard has any type of deficiency, pest or disease is to observe its stems, its grapes and/or its leaves. To place a sensor in each leaf of every vineyard is obviously not feasible in terms ...
Análisis de la influencia de la densidad ósea aparente en el comportamiento a tracción y compresión de la estructura ósea trabecular vertebral basada en un modelo teórico de celda hexagonal.

Alcaraz Quintero, Adrián (Universitat Politècnica de València, 2022-10-18)

[ES] La resistencia frente a solicitaciones por parte del hueso es una de las competencias mecánicas más importantes de nuestro esqueleto. Si bien es necesario la existencia de un estado de deformación umbral para mantener ...
Characterizing and modeling backscattering in silicon microring resonators

Ballesteros García, Guillem; Matres Abril, Joaquín; Martí Sendra, Javier; Oton Nieto, Claudio José (Optical Society of America, 2011)

We present an experimental technique to characterize back-scattering in silicon microring resonators, together with a simple analytical model that reproduces the experimental results. The model can extract all the key ...
Could it be advantageous to tune the temperature controller during radiofrequency ablation? A feasibility study using theoretical models

Alba Martínez, José; Trujillo Guillen, Macarena; Blasco Giménez, Ramón Manuel; Berjano Zanón, Enrique (Informa Healthcare, 2011-09)

Purpose: To assess whether tailoring the Kp and Ki values of a proportional-integral (PI) controller during radiofrequency (RF) cardiac ablation could be advantageous from the point of view of the dynamic behaviour of the ...
Lumped Element Electrical Model based on Three Resistors for Electrical Impedance in Radiofrequency Cardiac Ablation: Estimations from Analytical Calculations and Clinical Data

Berjano, Enrique; D Avila, Andre (Bentham Science, 2013)

[EN] The electrical impedance measured during radiofrequency cardiac ablation (RFCA) is widely used in clinical studies to predict the heating evolution and hence the success of the procedure. We hypothesized that a model ...
Noise control by sonic crystal barriers made of recycled materials

Sánchez-Dehesa Moreno-Cid, José; García Chocano, Víctor Manuel; Torrent Martí, Daniel; Cervera Moreno, Francisco Salvador; Cabrera García, Suitberto; Simon, Francisco (Acoustical Society of America, 2011-03)

A systematic study of noise barriers based on sonic crystals made of cylinders that use recycled materials like absorbing component is reported here. The barriers consist of only three rows of perforated metal shells filled ...
Radio-frequency heating of the cornea: theoretical model and in vitro experiments

Berjano, Enrique; Saiz Rodríguez, Francisco Javier; Ferrero Corral, José María (Institute of Electrical and Electronics Engineers, 2002)

[EN] We present a theoretical model for the study of cornea heating with radio-frequency currents. This technique is used to reshape the cornea to correct refractive disorders. Our numerical model has allowed the study of ...
Relationship between roll-off occurrence and spatial distribution of dehydrated tissue during RF ablation with cooled electrodes

Trujillo Guillen, Macarena; Alba Martínez, José; Berjano, Enrique (Informa Healthcare, 2012-02)

Purpose: To study the relationship between roll-off (sudden increase in impedance) and spatial distribution of dehydrated tissue during RF ablation using a cooled electrode (temperatures around 100°C). Methods: We used ...
Single cigar-shaped nanopores functionalized with amphoteric amino acid chains: experimental and theoretical characterization

Ali, Mubarak; Ramirez Hoyos, Patricio; Nguyen, Hung Quoc; Nasir, Saima; Cervera, Javier; Mafe, Salvador; Ensinger, Wolfgang (American Chemical Society, 2012)

We present an experimental and theoretical characterization of single cigar-shaped nanopores with pH-responsive carboxylic acid and lysine chains functionalized on the pore surface. The nanopore characterization includes ...
Sound transmission through plates perforated with two periodic subwavelength hole arrays

Estrada, Héctor; Gómez Lozano, Vicente; Uris Martínez, Antonio; Candelas Valiente, Pilar; Belmar Ibáñez, Francisco; Meseguer Rico, Francisco Javier (IOP Publishing: Hybrid Open Access, 2011-03)

Theoretical results on sound transmission through plates perforated with compound periodic hole arrays are presented. Calculations are obtained by means of a model under the rigid-solid assumption, which is thoroughly ...
Use of magnets for reversible restoration in sculpture. The case of the Virgen de los Desamparados in Valencia (Spain)

Rodríguez-Rodríguez, Medina-Azahara; Ruiz-Gómez, Sandra; Pérez-García, Lucas; Mas-Barberà, Xavier (Elsevier, 2018)

[EN] In this paper, we present the use of a magnetic system for restoring a real piece of art: the Virgen de los Desamparados sculpture (1954) by the Valencian sculptor Silvestre d'Edeta (Valencia, Spain). This sculpture ...
