Integrated modeling with Top-Down approach in subsidiary industries

This article considers how conceptual design of industrial products is supported by current CAD systems. The case of subsidiary industries, or first tier suppliers, that must simultaneously deal with different customers and CAD platforms, receive special attention. Conceptual design is critical, since the large variety of fundamental product data managed (not just geometry) would be specified, modeled and interrelated (i.e. functional relations), to both simplify and ensure correctness and efficiency of the next design phases of current design, and make them easy to reuse, modify and redesign in the future. We give an approach to introduce conceptual design through top-down methodology and integrate it with final geometry. In this context, and in order to help subsidiary industries to improve their model quality, we propose the elaboration of product-oriented modeling guidelines, or “best modeling practices”, instead of CAD-oriented modeling guidelines. The approach has been validated by testing the conceptual design tools of two commercial high-end CAD systems at use in many subsidiary automotive industries

ParSketch: a Sketch-based Interface for a 2D Parametric Geometry Editor

ParSketch is a software prototype to evaluate the usability and functionality of a sketching interface aimed at defining 2D parametric sections. Currently, ParSketch interprets strokes which can be recognized as geometry (line, arc, circle, ellipse, or composed entities that are automatically segmented into those basic entities), or graphic gestures representing constraints (dimension, parallel, perpendicular, tangent, concentric, horizontal or vertical). From the functionality point of view, ParSketch compares to current commercial parametric CAD applications, as it offers many of the features provided by such applications. A theoretical analysis of the efficiency component of usability is provided that justifies the potential capability of sketching interfaces to compete with classical WIMP applications. Finally, a usability study is presented, which makes special emphasis in the satisfaction component of usability.The Spanish Ministry of Science and Education and the European Union (Project DPI2004-01373) supported this work.

Complete and Automated Generation of Configurable Virtual Prototypes of Products Based on Parameterization Tools and Rules. Application to a Case Study

[EN] In engineering, the 3D model of a product is essential. A 3D model allows making modifications by editing the characteristic modeling functions, which implies knowing in detail the process followed in the modeling. In addition, the flexibility in the configuration is limited, since the modifications are made on geometry and parameters that are dependent on each other. In this work, a parametric modeling approach allows the generation of 3D models with different specifications by modifying a reduced number of parameters. To demonstrate the functionality, an application has been developed, using Autodesk Inventor iLogic, for the modeling of an engine with V-cylinder arrangement. Taking as input key parameters (number of cylinders,¿), it can generate virtual prototypes with different configurations, facilitating the selection of the best product configuration by allowing to evaluate different alternatives.Veliz Vega, V.; Albert Gil, FE.; Aleixos Borrás, MN.

Xf-Rovim. A Field Robot to Detect Olive Trees Infected by Xylella Fastidiosa Using Proximal Sensing

[EN] The use of remote sensing to map the distribution of plant diseases has evolved considerably over the last three decades and can be performed at different scales, depending on the area to be monitored, as well as the spatial and spectral resolution required. This work describes the development of a small low-cost field robot (Remotely Operated Vehicle for Infection Monitoring in orchards, XF-ROVIM), which is intended to be a flexible solution for early detection of Xylella fastidiosa (X. fastidiosa) in olive groves at plant to leaf level. The robot is remotely driven and fitted with different sensing equipment to capture thermal, spectral and structural information about the plants. Taking into account the height of the olive trees inspected, the design includes a platform that can raise the cameras to adapt the height of the sensors to a maximum of 200 cm. The robot was tested in an olive grove (4 ha) potentially infected by X. fastidiosa in the region of Apulia, southern Italy. The tests were focused on investigating the reliability of the mechanical and electronic solutions developed as well as the capability of the sensors to obtain accurate data. The four sides of all trees in the crop were inspected by travelling along the rows in both directions, showing that it could be easily adaptable to other crops. XF-ROVIM was capable of inspecting the whole field continuously, capturing geolocated spectral information and the structure of the trees for later comparison with the in situ observations.This work was partially supported by funding from the European Union's Horizon 2020 research and innovation programme under grant agreement 727987 Xylella Fastidiosa Active Containment Through a multidisciplinary-Oriented Research Strategy (XF-ACTORS).Rey, B.; Aleixos Borrás, MN.; Cubero-García, S.; Blasco Ivars, J.

Development of an Application for the Automatic Evaluation of the Quality of 3D CAD Models

[EN] In the 3D modeling of products, the use of an adequate methodology that ensures the capture of the design intention is very important. The sequence of operations is key, like for instance, the sketches have to be completely restricted and the references of the modelling functions have to be correctly chosen without generating unwanted dependency relationships, among others. In the best of cases, the team leader dictates best practice manuals and then supervises the design work, ensuring that quality, which will facilitate future modifications or new designs based on existing models. However, this is not an established process, causing multiple failures in cascade when modifying or reusing the models is approached. This work has consisted of the development of an application that allows the automation of the quality analysis process in the models and has been developed for the Autodesk Inventor application using its iLogic tool. This work is the result of a Master¿s Thesis, where for the evaluation of the developed application, the examination models of the students of the subject of Graphic Engineering of the 4th year of the Degree in Engineering in Industrial Technologies of the Universitat Politècnica de València have been used.Pou Schmidt, I.; Rodriguez Ortega, A.; Albert Gil, FE.; Aleixos Borrás, MN.

Estudio de la evolución de la calidad de granada Mollar de Elche durante su maduración usando sistemas de visión artificial

En el presente trabajo se ha estudiado la capacidad de la visión artificial para monitorear la evolución de diferentes propiedades fisicoquímicas de la granada ‘Mollar de Elche’ durante su madurez. Para ello se han obtenido imágenes hiperespectrales y RGB de 30 frutas intactas y sus arilos durante siete recolecciones consecutivas cada 2 semanas (210 frutos en total). En cada fruta se han medido las propiedades de peso, diámetro, sólidos solubles totales (SST), acidez, la actividad antioxidante y el contenido en fenoles totales. Posteriormente, la información espectral (450-1050 nm) y de color (L*, a* y b*) obtenida de las imágenes de las frutas intactas y arilos se ha correlacionado con las propiedades fisicoquímicas mediante el método multivariante de mínimos cuadrados parciales. En el caso de fruta intacta, ambos métodos de visión obtuvieron resultados de predicción similares en todos los parámetros excepto en la actividad antioxidante, donde la imagen hiperespectral fue más precisa. En general, los parámetros predichos por estas técnicas que mayor precisión obtuvieron (R2 = > 0,75; RPD = > 2) fueron el índice de madurez y BrimA, los parámetros de color de los arilos L* y a*, la actividad antioxidante y los fenoles totales. Sin embargo, en el caso de los arilos, la imagen hiperespectral predijo la mayoría de parámetros de manera más precisa (R2 = > 0,75; RPD = > 2) que la imagen RGB, la cual no obtuvo valores de  R2 = > 0,75 y RPD = > 2 en ningún parámetro. Estos resultados indican el gran potencial de la visión artificial, especialmente la imagen hiperespectral, para evaluar las propiedades de calidad de granadas intactas y de los arilos, ofreciendo la posibilidad de determinar el procesamiento al que irán destinadas estas frutas de manera no destructiva y rápida

Monitoring strategies for quality control of agricultural products using visible and near-infrared spectroscopy: A review

[EN] Background: The increasing demand for quality assurance in agro-food production requires sophisticated analytical methods for in-line quality control. One of these techniques is visible and near-infrared (VIS-NIR) spectroscopy, which has low running costs, does not need sample preparation, and is non-destructive, environmentally friendly, and fast. Despite these advantages, only a limited amount of research has been conducted on VIS-NIR in-line applications to measure, control, and predict quality in fruits and vegetables. Scope and approach: The applicability of VIS-NIR spectroscopy for the off-line and in-line monitoring of quality in postharvest products has been addressed in this review. The document focuses on the comparison between the two processes for the same agro-food product, highlighting the main advantages and disadvantages, problems, solutions, and differences. Key findings and conclusions: VIS-NIR techniques, combined with chemometric methods, have shown great potential due to their fast detection speed, and the possibility of simultaneously predicting multiple quality parameters or distinguishing between products according to the objectives. Being able to automate processes is a great advantage compared to routine off-line analyses, mainly due to the savings achieved in time, material, and personnel. However, in numerous cases, in-line implementation has not been accomplished in the corresponding studies, hence the scarcity of real in-line applications. Recent demands, together with the advances being made in the technology and a reduction in the price of equipment, makes VIS-NIR technology an analytical alternative for continuous real-time food quality controls, which will become predominant in the next few years.This work was partially funded by INIA and FEDER funds through research project RTA2015-00078-00-00.Victoria Cortés López thanks the Spanish Ministry of Education, Culture and Sports for the FPU grant (FPU13/04202).Cortes-Lopez, V.; Blasco Ivars, J.; Aleixos Borrás, MN.; Cubero-García, S.; Talens Oliag, P.
