    • A smart system for the automatic evaluation of green olives visual quality in the field 

      Sola Guirado, Rafael Rubén; Bayano Tejero, Sergio; Aragón-Rodríguez, Fernando; Bernardi, Bruno; Benalia, Souraya; Castro García, Sergio (Elsevier, 2020)
      Monitoring some of the parameters that affect the quality of table olives for green processing is fundamental in a farmer's decision making. This work develops an affordable system for in-the-field evaluation of fruit ...

    • Assessment of the Accuracy of a Multi-Beam LED Scanner Sensor for Measuring Olive Canopies 

      Sola Guirado, Rafael Rubén; Bayano-Tejero, Sergio; Rodríguez Lizana, Antonio; Gil Ribes, Jesús; Miranda Fuentes, Antonio (MDPI, 2018)
      Canopy characterization has become important when trying to optimize any kind of agricultural operation in high-growing crops, such as olive. Many sensors and techniques have reported satisfactory results in these approaches ...

    • Fruit abscission pattern of ‘Valencia’ orange with canopy shaker system 

      Aragón-Rodríguez, Fernando; Castro García, Sergio; Sola Guirado, Rafael Rubén; Gil Ribes, Jesús (2019)
      Fruit detachment can occur due to natural causes or be mechanically performed by a combination of mechanical stresses that cause tissue breakage in the plant. Forced abscission should not coincide with natural abscission ...

    • In-Field Estimation of Orange Number and Size by 3D Laser Scanning 

      Méndez, Valeriano; Pérez-Romero, Antonio; Sola Guirado, Rafael Rubén; Miranda Fuentes, Antonio; Manzano Agugliaro, Francisco; Zapata-Sierra, Antonio; Rodríguez Lizana, Antonio (MDPI, 2019)
      The estimation of fruit load of an orchard prior to harvest is useful for planning harvest logistics and trading decisions. The manual fruit counting and the determination of the harvesting capacity of the field results ...

    • La maqueta como herramienta de aprendizaje para desarrollo de maquinaria agrícola 

      Sola Guirado, Rafael Rubén; Gil Ribes, Jesús; Agüera Vega, Juan; Castro García, Sergio; González Sánchez, Emilio Jesús; Blanco Roldán, Gregorio L. (UCOPress, 2019)
      Se propone la introducción de un ejercicio basado en proyectos en la asignatura de “Diseño de maquinaria agraria. Automática agraria”. Para resolver el problema los alumnos han de pasar por todas las fases de las metodologías ...

    • Mechanical canopy and trunk shaking for the harvesting mechanization of table olive orchards 

      Sola Guirado, Rafael Rubén; Castillo-Ruiz, Francisco J.; Blanco Roldán, Gregorio L.; González Sánchez, Emilio Jesús; Castro García, Sergio (Universidad Nacional de Cuyo; Facultad de Ciencias Agrarias; Centro Coordinador de Ediciones Académicas, 2020)
      Table olive harvesting is highly dependent on manual labour and may jeopardize the crop benefit. The introduction of a mechanical harvest system requires a global evaluation of the whole process. A trunk shaker along with ...

    • Olive Actual “on Year” Yield Forecast Tool Based on the Tree Canopy Geometry Using UAS Imagery 

      Sola Guirado, Rafael Rubén; Castillo-Ruiz, Francisco J.; Jiménez Jiménez, Francisco; Blanco Roldán, Gregorio L.; Gil Ribes, Jesús; Castro García, Sergio (MDPI, 2017)
      Olive has a notable importance in countries of Mediterranean basin and its profitability depends on several factors such as actual yield, production cost or product price. Actual “on year” Yield (AY) is production (kg ...

    • Olive Crown Porosity Measurement Based on Radiation Transmittance: An Assessment of Pruning Effect 

      Castillo-Ruiz, Francisco J.; Castro García, Sergio; Blanco Roldán, Gregorio L.; Sola Guirado, Rafael Rubén; Gil Ribes, Jesús (MDPI, 2016)
      Crown porosity influences radiation interception, air movement through the fruit orchard, spray penetration, and harvesting operation in fruit crops. The aim of the present study was to develop an accurate and reliable ...

    • The contribution of fruit and leaves to the dynamic response of secondary branches of orange trees 

      Castro García, Sergio; Aragón-Rodríguez, Fernando; Arias Calderón, Rocío; Sola Guirado, Rafael Rubén; Gil Ribes, Jesús (Elsevier, 2020)
      The current commercial technologies for mass harvesting fruit are based on the application of forced vibration to the tree, which is transmitted to the fruits causing their detachment. The dynamic behaviour of the plant ...

    • The vibration behaviour of hedgerow olive trees in response to mechanical harvesting with straddle harvester 

      Sola Guirado, Rafael Rubén; Aragón-Rodríguez, Fernando; Castro García, Sergio; Gil Ribes, Jesús (Elsevier, 2019)
      Understanding tree behaviour under mechanical harvesting is very important for orchard management and machine design. The objective of this work is to determine the Dynamic response of trees, in a hedgerow arrangement, to ...
