Valorization of mining by-products for rammed Earth construction
(Springer, 2024-07-27) Martín Antunes, Miguel Ángel; Seco Meneses, Andrés; Perlot, Céline; McGregor, F.; Ingeniería; Ingeniaritza; Institute of Smart Cities - ISC; Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa
Mining and manufacturing produce large amounts of waste. One effective way for the valorization of many inert wastes or by-products from these industries is their use for the development of sustainable construction materials. This work analyzes the ability of different mix proportions of two by-products from mining, a mining clayed sludge, and a spent foundry sand, for the formulation of a by-products based rammed earth construction material. To achieve this objective an experimental laboratory campaign was developed. First, the physic-chemical properties of both by-products were measured, and the geotechnical properties of clayed sludge especially clay content and granulometry were evaluated. Then, these four by-product materials were combined to create three different combinations of soils with continuous granulometric curves, adequate for rammed earth construction, following the available literature. A Standard Proctor test was carried out to determine the optimum dry density and optimal water content of the mixes. Then, the mechanical strength was characterized by Unconfined Compressive Strength (UCS) tests. The proportions of the materials with higher bulk density show a direct relationship with the UCS values obtained. Water immersion was considered for the characterization of the durability of the developed material. During the durability test, the samples lost their integrity. This work shows the ability of these by-product mixes to produce even more sustainable rammed earth constructions with 100% of recycled constituents, achieving the mechanical strength requirement, not durability ones. Further investigations are required to improve this by-product made soil durability performance.

Modal frequency and damping estimation of wind turbines: analysis of a wind farm
(Springer, 2024-06-22) Legaz Catena, Asier; Zivanovic, Miroslav; Iriarte Goñi, Xabier; Plaza Puértolas, Aitor; Carlosena García, Alfonso; Ingeniería Eléctrica, Electrónica y de Comunicación; Ingeniaritza Elektrikoa, Elektronikoa eta Telekomunikazio Ingeniaritza; Institute of Smart Cities - ISC; Ingeniería; Ingeniaritza
In this paper, we present an in-depth analysis carried out on several units of the same Wind Turbine (WT) model installed in a wind farm. We have collected simultaneous data under several different operating conditions ranging from the idling state to nominal power close to cut-out. Both frequency and damping parameters have been estimated for the first and second Fore-Aft (FA) and Side-Side (SS) tower modes. As far as we know, there are no previous publications combining data from so many turbines, operating conditions, and for a time period spanning several months. We have made use of a novel strategy to isolate the modes and minimize the influence of harmonics, using an algorithm previously proposed by the authors. The main conclusion is that estimated modal frequencies allow for a clear discrimination between turbines, whereas damping ratios, subjected to much wider deviations, do not seem to be very discriminant. We show here results for only one operating mode (nominal power), for which the method has been tuned. The analysis of other operating modes and longer periods, now under consideration, will allow for more conclusive results.

SteCal: a powerful tool for improving the student engagement in the design and development of low-alloys steels for high performance applications
(Servicio Editorial de la Universidad del País Vasco-Euskal Herriko Unibertsitateko Argitalpen Zerbitzua, 2019) Rivero Fuente, Pedro J.; Ingeniería; Ingeniaritza; Institute for Advanced Materials and Mathematics - INAMAT2
In this work, it is presented the use of a specific software known as SteCal 3.0 (Microsoft Windowsbased application) which is successfully employed as a didactic and instructional method for future students in Engineering Degrees (mostly Mechanical Engineering, Mechanical Design Engineering and Industrial Technologies Engineering, among others). First of all, it is important to remark that steel is one of the most important metallic materials in our society which can be widely used in a high variety of different sectors such as automotive, construction, structural, packaging or manufacturing, among others. One of the main reasons of this great multifunctionality is associated to its intrinsic properties such as a high mechanical resistance and hardness combined with a high toughness and easy formability. According to this, SteCal is very useful software for comparing the properties of several steels with different chemical composition, which can help to suggest the most appropriate composition for a specific application. As a function of the input experimental parameters (varying alloying elements), this program can help to the students a better comprehension on diverse metallurgical aspects obtainable with low-alloy steels such as thermal behaviour (austenizing temperature, eutectoid reaction, normalizing, quenching, tempering) as well as important concepts related to the resultant mechanical properties (martensitic structure, susceptibility to quench-cracking, hardness, Jominy End-Quench hardenability). Due to this, two different types of steel with different chemical composition are evaluated according to the designation from the American Iron and Steel Institute (AISI) such as AISI 1330 and AISI 4147, respectively. Finally, a better student engagement has been observed along all these years of implementation of this didactic software because the future students in Engineering Degrees can deep about theoretical and important concepts with the aim of designing steels with specific properties of high technological interest.

An optical fiber sensor for Hg2+ detection based on the LSPR of silver and gold nanoparticles embedded in a polymeric matrix as an effective sensing material
(MDPI, 2021-07-07) Martínez Hernández, María Elena; Sandúa Fernández, Xabier; Rivero Fuente, Pedro J.; Goicoechea Fernández, Javier; Arregui San Martín, Francisco Javier; Ingeniería Eléctrica, Electrónica y de Comunicación; Ingeniaritza Elektrikoa, Elektronikoa eta Telekomunikazio Ingeniaritza; Institute of Smart Cities - ISC; Ingeniería; Ingeniaritza; Institute for Advanced Materials and Mathematics - INAMAT2; Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa
In this work, an optical fiber sensor based on the localized surface plasmon resonance (LSPR) phenomenon is presented as a powerful tool for the detection of heavy metals (Hg2+). The resultant sensing film was fabricated using a nanofabrication process, known as layer-by-layer embedding (LbL-E) deposition technique. In this sense, both silver nanoparticles (AgNPs) and gold nanoparticles (AuNPs) were synthesized using a synthetic chemical protocol as a function of a strict control of three main parameters: polyelectrolyte concentration, loading agent, and reducing agent. The use of metallic nanostructures as sensing materials is of great interest because well-located absorption peaks associated with their LSPR are obtained at 420 nm (AgNPs) and 530 nm (AuNPs). Both plasmonic peaks provide a stable real-time reference that can be extracted from the spectral response of the optical fiber sensor, giving a reliable monitoring of the Hg2+ concentration.

Water footprint of a 5 kg bag of washed potatoes
(Cal-Tek srl, 2023) Sáenz Baños, Mercedes Irache; Latorre Biel, Juan Ignacio; Martínez Cámara, Eduardo; Jiménez Macías, Emilio; Blanco Fernández, Julio; Ingeniería; Ingeniaritza
Climate change and water scarcity increasingly impact agricultural systems. Therefore, studying food systems in depth through a water footprint perspective and their effects on water resources is necessary. Potatoes are one of the most widely consumed foods globally. This article analyzes the water footprint of a 5 kg bag of washed potatoes using a life cycle assessment (LCA) methodology. A cradle-to-gate model is created, and four environmental impact assessment methods are applied to determine the impacts on water resources. The results obtained are consistent across all four methods, indicating that water consumption in the potato washing stage has the most significant impact. The second highest water consumption occurs during the agricultural cultivation phase. Furthermore, this agricultural phase has the highest impact on other water-related categories, including such as Water Pollutants, Persistent Organic Pollutant (POP) into Water, Heavy Metals into Water, and Radioactive Substances into Water.

Convolutional neural networks for the detection of esca disease complex in asymptomatic grapevine leaves
(Springer, 2024-01-24) Carraro, Alberto; Saurio, Gaetano; López Maestresalas, Ainara; Scardapane, Simone; Marinello, Francesco; Ingeniería; Ingeniaritza; Institute on Innovation and Sustainable Development in Food Chain - ISFOOD
The Esca complex is a grapevine trunk disease that significantly threatens modern viticulture. The lack of effective control strategies and the intricacy of Esca disease manifestation render essential the identification of affected plants before symptoms become evident to the naked eye. This study applies Convolutional Neural Networks (CNNs) to distinguish, at the pixel level, between healthy, asymptomatic and symptomatic grapevine leaves of a Tempranillo red-berried cultivar using Hyperspectral imaging (HSI) in the 900¿1700 nm spectral range. We show that a 1D CNN performs semantic image segmentation (SiS) with higher accuracy than PLS-DA, one of HSI data¿s most widely used classification algorithms.

Comprehensive analysis of rotor edgewise whirling mode interaction with rotor speed harmonics
(IOP Publishing, 2024) Torres Elizondo, Antonio; Gil Soto, Javier; Plaza Puértolas, Aitor; Aginaga García, Jokin; Ingeniería; Ingeniaritza; Institute of Smart Cities - ISC
This paper presents a model that investigates the interaction between rotor edgewise whirling modes and rotor speed harmonics in wind turbines. The model is based on kinematic and dynamic principles, with a focus on the multi-blade coordinate transformation, which is critical for simulating the behaviour of the rotor whirling modes in wind turbines. The research has two objectives: to investigate the interaction between the rotor edgewise whirling modes and the rotor speed harmonics, and to provide clearer graphs that explain the complex nature of this non-intuitive rotor dynamics. The paper concludes by highlighting the practical implications of the research findings, in particular the effectiveness of visualisation techniques in identifying and explaining unexpected interactions.

Efficient geometric parametrization of blades cross-sections by means of B-splines
(IOP Publishing, 2024) Llamazares, G.; San Miguel, Unai; Plaza Puértolas, Aitor; Ingeniería; Ingeniaritza
Optimization and enhancement of rotor blade design are critical to improving the productivity of the wind energy industry. Airfoil geometry is a key factor that makes airfoil design and optimization a common task for aerodynamicists. Ensuring proper airfoil parametrization is essential. It serves as the first step in aerodynamic optimization, where the efficiency is directly related to the geometric complexity. This research presents a cost-effective and robust method for fitting airfoils using B-splines. We take into account factors such as computational cost, resource requirements, and accuracy. In this work, we present a method for minimizing the geometric distances between target points and a B-spline curve. We streamline the fitting process, create a computational Python package, and explore different approaches, objective functions, algorithms, and error tolerance settings. The work concludes that it is highly recommended to use an iterative fitting process, to adequately represent common airfoils with B-splines. Moreover, the accuracy and the computational cost can be managed subject to the minimization algorithm used, and the technique utilized for the objective cost calculation. The fitting procedure we develop in this study gives the smallest number of variables capable of accurately representing a desired airfoil.

Computational investigation of the effect of the trailing edge thickness on the wind turbine performance
(IOP Publishing, 2024) Echenique, Daniel; Plaza Puértolas, Aitor; Gutiérrez Amo, Rubén; Ingeniería; Ingeniaritza
Trailing edge (TE) thickness is a manufacturing constraint in blade design, especially for airfoils with a sharp TE. To achieve a specific TE thickness, blade geometry is often modified during the design process, typically in the outer zone of the blade where the airfoil's TE is thinner. This area has a significant impact on energy production and loads. Quantifying the effect of TE thickness modifications is crucial for making informed design decisions. Therefore, this study quantifies and compares the impact of linear and polynomial geometry modifications on airfoil aerodynamics and turbine performance. Xfoil and OpenFAST were used to calculate these performance variations in the well-known NREL 5 MW wind turbine. The TE thickness of the model was modified to meet various manufacturing constraints, ranging from no restriction to a limit of 12mm TE thickness. In terms of the aerodynamic behavior of the airfoils, the maximum efficiency of airfoils with low relative thickness decreases as the TE thickness increases. Annual Energy Production shows a reduction of up to 0.42% for the worst case, while blade root loads increase by up to 20%. For low relative thickness airfoils, the linear method has proven to be a better option with less impact on performance.

A directivity correction for accurate semi-empirical wind turbine noise prediction
(IOP Publishing, 2024) Saldaña Barroso, Oier; Rautmann, C.; Plaza Puértolas, Aitor; Ingeniería; Ingeniaritza
Public acceptance of wind farms is a significant challenge in the development of wind energy. The acoustic impact generated by wind turbines is a common concern among local residents. The primary noise source in wind turbines is generated by aerodynamics. Atmospheric turbulence reaching the blade leading edge or turbulent boundary layer passing the trailing edge produce the main aeroacoustic sources. The noise generated by these mechanisms is commonly predicted by means of semi-empirical models, which do not demonstrate great reliability when compared to acoustic measurements. This paper presents a correction to the directivity of airfoil noise radiation, resulting in improved sound pressure levels on the ground plane surrounding a wind turbine. This improvement is achieved without requiring any additional computational effort. The sound pressure levels perceived on the ground plane are known to have asymmetrical shape. Maximum noise levels correspond to observers directly in the upwind and downwind locations, whereas the minimum levels belong to the positions close to the rotor plane. Said asymmetrical shape is not represented in the semi-empirical models. The proposed correction takes into consideration the airfoil thickness in the radiation directivity equations, resulting in the expected asymmetrical shape of noise footprints on the ground plane around a wind turbine. The correction was found to not affect the accuracy of the spectrum predicted by the semi-empirical models when compared to dedicated field measurements under the standard IEC 61400-11 procedure. When implementing the proposed correction, the virtual NREL 5 MW wind turbine's published noise footprints, which were originally calculated using computationally expensive methods, are accurately reproduced.

AI training for application to industrial robotics: trajectory generation for neural network tuning
(Springer, 2023) Merino Olagüe, Mikel; Ibarrola Chamizo, Javier; Aginaga García, Jokin; Hualde Otamendi, Mikel; Ingeniería; Ingeniaritza; Institute of Smart Cities - ISC
In the present work robot trajectories are generated and kinematically simulated. Different data (joint coordinates, end effector position and orientation, images, etc.) are obtained in order to train a neural network suited for applications in robotics. The neural network has the goal of automatically generating trajectories based on a set of images and coordinates. For this purpose, trajectories are designed in two separate sections which are conveniently connected using Bezier curves, ensuring continuity up to accelerations. In addition, among the possible trajectories that can be carried out due to the different configurations of the robot, the most suitable ones have been selected avoiding collisions and singularities. The designed algorithm can be used in multiple applications by adapting its different parameters.

Electrospinning technique as a powerful tool for the design of superhydrophobic surfaces
(IntechOpen, 2020) Rivero Fuente, Pedro J.; Vicente Gómara, Adrián; Rodríguez Trías, Rafael; Ingeniería; Ingeniaritza; Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, PJUPNA1929
The development of surface engineering techniques to tune-up the composition, structure, and function of materials surfaces is a permanent challenge for the scientific community. In this chapter, the electrospinning process is proposed as a versatile technique for the development of highly hydrophobic or even superhydrophobic surfaces. Electrospinning makes possible the fabrication of nanostructured ultrathin fibers, denoted as electrospun nanofibers (ENFs), from a wide range of polymeric materials that can be deposited on any type of surface with arbitrary geometry. In addition, by tuning the deposition parameters (mostly applied voltage, flow rate, and distance between collector/needle) in combination with the chemical structure of the polymeric precursor (functional groups with hydrophobic behavior) and its resultant viscosity, it is possible to obtain nanofibers with highly porous surface. As a result, functionalized surfaces with water-repellent behavior can be implemented in a wide variety of industrial applications such as in corrosion resistance, high efficient water-oil separation, surgical meshes in biomedical applications, or even in energy systems for long-term efficiency of dye-sensitized solar cells, among others.

Monitoring the thermal potential of low-cost radiative cooling materials under static and dynamic conditions of exposure
(Morlacchi Editore University Press, 2023) Chiatti, Chiara; Kousis, Ioannis; Fabiani, Claudia; Carlosena Remírez, Laura; Pisello, Anna Laura; Ingeniería; Ingeniaritza
Reflecting the radiation of the sun while emitting thermal radiation to cold outer space has proven to be an effective solution against urban overheating. The latter severely impact the energy consumption of buildings, outdoor pollution levels, and heat-related morbidity and mortality, which is why recent research has focused on new advanced mitigation technologies to be implemented in cities. Passive radiative cooling (PRC) has the potential to provide a temperature lower than ambient without any energy consumption. While conventional cooling prototypes reject heat to the air, PRCs reject heat to the outer atmosphere emitting radiation mainly in the 8-13 ¿m range, i.e., the so-called atmospheric window. This work investigates the thermal behavior of different radiative cooling materials under various exposure conditions to examine their effective cooling potential. The basic structure of the samples comprehends a highly reflective substrate (aluminum or Vikuiti) and a silica-derived emissive layer. After a preliminary characterization under controlled environmental settings, the samples were exposed outdoors, and their superficial temperature was monitored during the central hours of the day. Comparisons among samples and a benchmark aluminum reference layer were made, also considering the weather data collected during the days of exposure. Although the samples did not reach sub-ambient temperatures during the monitoring, the emissive layer significantly reduced the surface temperature. Furthermore, the effect of a tunable intermediate layer placed between the substrate and the emissive element was demonstrated to positively impact the thermal performance of the sample, thanks to its capability of changing the emissivity spectrum with temperature.

Diseño de un mecanismo de propulsión para bicicleta capaz de almacenar y descargar energía mecánica producida por el usuario
(AEIPRO, 2013) Villanueva Roldán, Pedro; Corral Bobadilla, Marina; Lostado Lorza, Rubén; Illera Cueva, M.; Bona, J; Ingeniería; Ingeniaritza
La energía eléctrica todavía proviene en su mayor parte de combustiones fósiles y soluciones no ecológicas. En este artículo se describe una alternativa a la bicicleta eléctrica. Se muestra el proceso de diseño de un dispositivo aplicable a una bicicleta, formado únicamente por elementos mecánicos siguiendo una moda retro o steampunk. Tiene por objetivo divertir al usuario, produciendo un estímulo directamente relacionado con la velocidad y el esfuerzo físico. Tanto el almacenamiento de energía, como la descarga de la misma, se produce a voluntad del usuario. Por un lado, una vez alcanzada una velocidad adecuada al gusto del usuario o cuando él así lo desee, da marcha atrás con los pedales cargando así el dispositivo. Por otro lado, mediante una palanca descargará la energía que ha acumulado previamente. El diseño del componente está basado en el diferencial utilizado en la dirección dentro del sector de automoción, así como en los engranajes dotados con resortes utilizados en los coches de juguete, los cuales almacenan energía al hacerlos rotar. El nuevo dispositivo combina estos elementos aplicando modificaciones en los mismos para que su efecto se adapte a los objetivos deseados.

Modeling of MAG welding process using data mining techniques
(AEIPRO, 2011) Villanueva Roldán, Pedro; Ibarra Murillo, Martín; Lostado Lorza, Rubén; Sanz García, Andrés; Ingeniería; Ingeniaritza
La fabricación de componentes mecánicos mediante soldadura eléctrica es un proceso que se lleva aplicando con éxito en diferentes sectores desde comienzos del siglo XX (Automoción, Construcción, Aeronáutica…). Este proceso de fabricación presenta siempre el inconveniente de inducir sobre el componente fabricado elevadísimas tensiones y deformaciones residuales, obligando a un mecanizado posterior hasta poder ajustar a las tolerancias de diseño. El mecanizado posterior supone siempre un sobrecoste en el precio total de fabricación del componente soldado, aumentando este según el grado de mecanizado requerido. En este trabajo se expone la experiencia adquirida en la modelización del proceso soldadura MAG mediante técnicas de Minería de Datos. El objetivo principal es encontrar modelos predictivos de deformaciones angulares y de los espesores de los cordones de las soldaduras en función de los parámetros de configuración de la máquina de soldeo (intensidad, velocidad, ángulos, etc.), así como identificar los factores mas influyentes en la generación de las tensiones y deformaciones residuales.

Optimización de un freno de disco mediante la combinación del método de los elementos finitos y algoritmos genéticos
(AEIPRO, 2012) Zurrón-Barragán, Carlos; Olarte-Valentín, Rubén; Ramírez-Aragón, María Cristina; Villanueva Roldán, Pedro; Lostado Lorza, Rubén; Ingeniería; Ingeniaritza
Un freno de disco es un sistema de frenado que actúa sobre las ruedas motrices de los vehículos. Este dispositivo transforma toda o parte de la energía cinética del vehículo debida al movimiento en calor a fin de detenerlo o disminuir su velocidad. Cualquier freno de disco posee una parte móvil (el disco) y una rueda que gira, así como unas pastillas de fricción o de freno. Estas pastillas son los elementos que ejercen la presión y la adherencia sobre los propios discos. Hoy en día, el diseño de este tipo de dispositivos está basado tanto en estudios teóricos como en el Método de los Elementos Finitos (MEF). Uno de los principales inconvenientes de éste método es el ajuste de las condiciones de contorno del modelo y de los parámetros de material. En este trabajo, se muestra el ajuste y la validación experimental de un modelo de elementos finitos de un freno de disco completo. Este ajuste y validación del modelo se realizó mediante técnicas de Algoritmos Genéticos (GA).
