Asymmetric nanopore rectification for ion pumping, electrical power generation, and information processing applications

Cervera, Javier; Ramirez Hoyos, Patricio; Mafé, Salvador; STROEVE, PIETER (Elsevier, 2011-04)

Single-track, asymmetric nanopores can currently be functionalised with a spatially inhomogeneous distribution of fixed charges and a variety of pore tip shapes. Optimising the asymmetric nanopore characteristics is crucial ...
Centralized and Distributed Optimization Models for the Multi-Farmer Crop Planning Problem under Uncertainty: Application to a Fresh Tomato Argentinean Supply Chain Case Study

Alemany Díaz, María Del Mar; Esteso, Ana; Ortiz Bas, Ángel; del Pino, Mariana (Elsevier, 2021-03)

[EN] Imbalance between supply and demand of crops frequently occurs in markets originating an excess or shortage of supply in relation to demand. This causes high volatility and uncertainty in market prices, unmet demand, ...
Crop planting and harvesting planning: Conceptual framework and sustainable multi-objective optimization for plants with variable molecule concentrations and minimum time between harvests

Esteso, Ana; Alemany Díaz, María Del Mar; Ortiz Bas, Ángel; Iannacone, Rina (Elsevier, 2022-12)

[EN] The planting and harvesting of medicinal plants have characteristics that differentiate them from other crop types and complicate their planning. For example, drug processors do not require large quantities of product ...
Design and simulation of dual-band RF energy harvesting antenna for WSNs

Bakkali, Asma; Pelegrí Sebastiá, José; Sogorb Devesa, Tomás; Bou Escrivà, Antoni; Lyhyaoui, Abdel (Elsevier, 2017)

[EN] Radio frequency energy harvesting is attracting an increasing deal of attention in order to provide power to the electronic devices, including Wireless Sensor Networks. In this context, we focus on ambient radiofrequency ...
Design of a structural health monitoring system based on energy harvesting

Morellá Campos, Álvaro (Universitat Politècnica de València, 2023-09-29)

[ES] Este documento recopila el procedimiento para la realización del Trabajo de Final del Grado en Ingeniería Electrónica Industrial y Automática, que se basa en el diseño de un sistema de Medición de la Salud Estructural ...
Enhancement of sound in chirped sonic crystals

Romero García, Vicente; Picó Vila, Rubén; Cebrecos Ruiz, Alejandro; Sánchez Morcillo, Víctor José; Staliünas, Kestutis (American Institute of Physics (AIP), 2013)

We propose and experimentally demonstrate a mechanism of sound wave concentration based on soft reflections in chirped sonic crystals. The reported controlled field enhancement occurs at around particular (bright) planes ...
Estudio de costes de la recolección de naranjas por vibrador de troncos mediante análisis de sensibilidad

García Navarrete, Oscar Leonardo (Universitat Politècnica de València, 2011-09-09)

Para reducir los costes de la recolección de citricos se planteo un modelo de costes del método de recolección por vibración de troncos identificando las variables más influyentes en el coste y estableciendo un límite de ...
Estudio del papel de las permeasas de la familia AAP de tomate (Solanum lycopersicum L.) en la partición de aminoácidos para producción de fruto. Relación con el aporte de nitrógeno a la planta

Carreres Creus, Paula (Universitat Politècnica de València, 2023-09-06)

[ES] La familia de permeasas AAP se ha descrito como clave en la partición de aminoácidos en Arabidopsis y cultivos como el guisante o el arroz. Sin embargo, hay muy poca información sobre el papel de las AAPs en especies ...
Estudio sobre vibraciones en sistemas de recolección del olvar

Villalba Bertolín, María Ángeles (Universitat Politècnica de València, 2016-07-29)

[EN] The use of shakers in olive harvesting involves the risk of hand vibration exposure. The aim of this study was to assess the operator vibration exposure using different harvesting devices.
Feasibility of peach bloom thinning with hand-held mechanical devices

Martín Gorriz, B.; Torregrosa, A.; García Brunton, J. (Elsevier, 2011-05-25)

[EN] The use of hand-held mechanical devices to thin blooms of peach trees trained into the " free Italian vase" form was studied. Three devices were tested, and no differences were found among them in terms of thinning ...
