The development of 3D modeling tools has allowed the construction of geometries that were unattainable computationally until a few decades ago. Specifically, parametric design and modeling is gaining significant importance in the conceptualization of new designs and products. This communication shows some of the resulting prototypes, designed and manufactured by INNANOMAT research group (TEP 946) of Cadiz University. A product design methodology for Additive Manufacturing (AM) and functional luminaire models proposed in the scope of two projects: ADICORK and 3DBLEND. In these projects, bio-inspired texture designs were explored in natural elements and environments of the province of Cádiz, in order to highlight this region and the value of its ecosystem. In both projects, sustainable polymeric blends were developed that served as base material for the manufacture of part of the prototypes shown in this communication. For these designs, parametric design programs such as Grasshopper, a Rhinoceros plugin, were used to obtain complex models that achieve a unique and differentiating aesthetic. The result of the modeled texturing is combined with surfaces in Rhinoceros. Once the textured model is defined, it is detailed and finished in modeling programs where dimensional control is greater, and the design is adjusted to the specific AM technology chosen. In this case two were used, Fused Filament Fabrication (FFF) and Fused Granular Fabrication (FGF). Keywords: Parametric design; Fused Granular Fabrication; Additive Manufacturing; product design; Biomimicry
随着三维建模工具的发展，人们可以构建出几十年前还无法通过计算实现的几何形状。具体而言，参数化设计和建模在新设计和产品的概念化过程中正变得越来越重要。这篇通讯展示了加的斯大学 INNANOMAT 研究小组（TEP 946）设计和制造的一些原型。在两个项目范围内提出了用于快速成型制造（AM）的产品设计方法和功能性灯具模型：ADICORK和3DBLEND。在这些项目中，在加的斯省的自然元素和环境中探索了生物启发的纹理设计，以突出该地区及其生态系统的价值。在这两个项目中，都开发了可持续的聚合物混合物，作为制造本交流中展示的部分原型的基础材料。在这些设计中，使用了参数化设计程序，如 Grasshopper（Rhinoceros 的一个插件），以获得复杂的模型，实现独特和与众不同的美感。模型纹理的结果与 Rhinoceros 中的曲面相结合。纹理模型确定后，在建模程序中对其进行细化和加工，在建模程序中尺寸控制更强，设计也会根据所选的特定 AM 技术进行调整。在本案例中，使用了两种技术：熔融长丝制造（FFF）和熔融颗粒制造（FGF）。关键词参数化设计；熔融粒状制造；增材制造；产品设计；仿生学

Design for safety is a branch of design that is based on identifying and fighting risks with the objective of increasing safety, well-being and health. Safety is a human right and it should be intrinsic to the entire design process. To ensure a correct evolution of design for safety, the development of new technologies that can offer efficient solutions to current problems must be taken into account. The aim of this work is to identify a series of synergies between design and safety in order to establish a common framework between these two areas and to develop new lines of research. To do this, we start with a mind map made with the collaboration of several safety professionals and researchers, from which we identify some of the main branches of design that already have a clear connection with safety or it could be further developed. Subsequently, the previous research related to each branch and their respective applications are analysed. The work concludes with the synthesis and representation of the results in a visual and easy-to-understand infographic, that compiles the identified synergies. These results offer valuable conclusions on the synergies between design and safety, helping to identify emerging applications and new trends. In addition, the bibliographic analysis provides insight into the most developed synergies in the academic field and those new ones that may represent a research niche.

Electrolysis is a chemical process that uses electric current to carry out chemical reactions. It was first discovered by the British scientist Michael Faraday in 1833, who conducted a series of experiments in which he passed an electric current through solutions of salts in water. He found that positively charged ions, known as cations, moved towards the negative electrode (anode), while negatively charged ions, known as anions, moved towards the positive electrode (cathode). Faraday also showed that the amount of substance deposited on the electrodes during electrolysis is proportional to the intensity of the electric current and the time of application.

The implementation of hydrogen as a fuel in industrial applications is an upward trend, and poses a challenge for the design of furnace burners. This article aims to advance in the knowledge of hydrogen combustion, through numerical simulation using SIEMENS STAR-CCM+ code. Several simulations have been carried out with the geometry of a 2.5 MW burner of the current SIDENOR furnace. The fuel burning there, is natural gas. Using the same geometry and the same mesh, a comparison is made between current temperatures and those that would arise when burning hydrogen, as well as mass fractions of other elements such as NOx. Maintaining the power of 2.5 MW and taking into account the lower heating value of methane and hydrogen, the inlet boundary conditions are calculated for the different fuel compositions. In this way it can be seen, qualitatively, the amount of hydrogen needed to meet the necessary temperatures in the billets, without excessive NOx production. Key Words: Hydrogen, burners, Computational Fluid Dynamics, NOx

In recent years, the interest in capturing wave energy has increased notably due to the immense potential available and the need to deepen and diversify the use of renewable energies. Oscillating Water Column (OWC) technology is one of the most technologically developed, with the world's first grid-connected demonstration plant located in Mutriku. However, the efficiency of this technology is still insufficient for its consolidation in the energy mix. Therefore, the present work presents an advance in the increase in the extraction of energy from the incident waves through the installation of a frontal ramp that directs the wave flow towards the vertical chamber of the oscillating column. The improvement achieved will be determined by means of a CFD (Computational Fluid Dynamics) 2D scaled model, which represents the interaction of the structure with different incident wave states. Different geometric options of the ramp are analyzed in comparison with the usual vertical wall option where the phenomenon of pure reflection occurs. This work aims to contribute to improving the efficiency of OWC technology, favoring the use of wave energy as a renewable energy source. Keywords: Oscillating Water Column (OWC), wave energy converter (WEC), Response Amplitude Operator (RAO), Computational Fluid Dynamics (CFD), wave energy
近年来，由于波浪能的巨大潜力以及深化和多样化利用可再生能源的需要，人们对捕捉波浪能的兴趣明显增加。振荡水柱（Oscillating Water Column，OWC）技术是技术最发达的技术之一，世界上第一个并网示范电站位于 Mutriku。然而，该技术的效率仍不足以将其纳入能源组合。因此，本研究提出了一项先进技术，即通过安装一个正面斜坡，将波流引向振荡柱的垂直腔体，从而提高从入射波中提取能量的能力。所取得的改进将通过 CFD（计算流体动力学）二维缩放模型来确定，该模型表示了结构与不同入射波状态的相互作用。与发生纯反射现象的通常垂直壁方案相比，对斜面的不同几何方案进行了分析。这项工作旨在提高振荡水柱技术的效率，促进波浪能作为可再生能源的利用：振荡水柱 (OWC)、波浪能转换器 (WEC)、响应振幅算子 (RAO)、计算流体动力学 (CFD)、波浪能

This study considers the design and development of a sport good with structural and vibration damping requirements, such as a bicycle handlebar. The methodology developed and the gained experience can later be applied to other types of sport goods. The study begins with the selection and subsequent characterisation of sustainable material systems, as well as their comparison with other conventional materials. For this purpose, the mechanical properties and the damping factor of the material were analysed in both flat and tubular samples, taking into account the orientation of the reinforcement fibers. The experimental results are used in the development of the handlebar, simulating by means of finite elements the structural behaviour under the load cases established in the standard, and the vibrational response. Once this behaviour has been optimised, prototypes are manufactured using both composite materials with natural reinforcements, in this case flax, and carbon fiber reinforcements. The prototypes are tested to validate and compare the behaviour at component level and the necessary improvements are proposed in order to comply with all the specifications that this type of product must meet. Keywords: Natural composites; sustainability; vibration damping; cycling.

This research is focused on the design of sustainable cultural services. Particularly, on the services associated with outdoor exhibitions, which represent an interesting alternative to traditional cultural services, being accessible to all populations, at any time and without ticketing. Open-air exhibitions are usually organized using different supports but the ones with counterweights are the most popular and versatile types. Sustainability aspects of three different design alternatives are studied. In the first alternative cultural content is exposed using printed and replaceable vinyl; in the second alternative, the exhibition is illuminated and content is printed on stretched canvas. The third alternative offers an additional service because when the display panels are replaced exhibitors are transformed into street furniture. The entire life cycle of the services has been reviewed. Moreover, environmental, economic, and social sustainability dimensions have been quantitatively evaluated using, respectively, the global warming potential, the execution costs, and the working time indicators. Thus, the study contributes to integrating sustainability in the design of service systems. The presented cases illustrate the sustainability assessment methods that could be used in the evaluation of different cultural services proposals and results obtained show that different alternatives can be selected according to the criteria applied to reflect the importance of each sustainability dimension. Keywords: Sustainability, design; Service life cycle; Cultural exhibitions; LCSA.

This work presents a review of the three main axes that constitute the knowledge base when designing products for additive manufacturing in the medical industry: technology, materials and design tools. Through four different study cases of diverse medical products that match the existing categories in the established classification of standards, different design approaches and strategies are presented and suggested as feasible solutions that generate medical products. These cases studies intend to cover some categories where additive manufacturing can be used in the medical sector: a post-surgery protection cast developed using reverse engineering technologies and free-form modelling tools customized not only regarding anatomic shapes but also in terms of aesthetics, a surgical simulator that improves the surgeon’s education process in a non-expensive manner, which could also be shared and spread combining soft and hard parts, a hip surgery retractor designed together with experts that increase the performance of the commercial solutions and a bone replacement implant with an innovative approach that combines engineering polymers with metallic surface coatings. All these case studies present the diversity of possible applications when working with the medical industry, as well as the required skills and knowledge needed to start with this task. Beside this, it has been stated the convenience of engineers to work hand by hand with medical professionals, combining skills and visions to innovate and improve the patient’s journey.

Even though there are numerous solutions for this process in the literature, calculating adequate vehicle routes for collecting municipal waste is still an open problem. There is still a disconnection between academics and industry professionals. The fact that academic tools are frequently difficult for actual users to operate and maintain is one of the apparent causes of this rift. The issue of municipal rubbish collection is modelled in this work utilizing a user friendly but effective—and notably straightforward—solution. The solution was based on Artificial Intelligence (AI) techniques and applied to real-world data. Three cases of different magnitudes were resolved, and in each case, a significant improvement was made. Specifically, a total theoretical reduction of 49% of the itineraries was achieved, which was partially adopted by the waste collection company as it had to consider additional restrictions.

Currently, the installed wind power capacity around the world in offshore installations is more than 60 GW, with a much higher growth rate than traditional onshore installations. This is due to the lack of barriers in the high seas, which means that air flows at a higher and more regular speed, allowing a greater amount of energy to be generated than in traditional onshore installations, which can even double it.
