An Oscillating Water Column device, specifically a Savonius turbine, underwent comprehensive testing within an air duct to evaluate its performance under varying rotational speeds, flow directions, and the presence of power augmenters positioned both in front of and behind the device. The experimental setup involved the utilization of load cells and pressure transducers, with their data utilized to calculate pressure differentials across the turbine and torque. Subsequently, a predictive model based on decision trees was developed using Machine Learning. This model was then used to analyze the influence of various features on predicting the pressure difference, considered as the output. The results of the validation (10-fold cross-validation) and test phases were thoroughly investigated. Moreover, obtaining a predictive model allows for the exploration of different scenarios without relying solely on physical experimentation, thereby broadening the scope for further testing.

“…Through these phases, it is possible to identify and quantify resource consumption and emissions, thus providing a solid foundation for the development of sustainable improvement strategies. The methodology lends itself to application in all sectors of industry, such as aerospace [18], manufacturing [19], automotive [20], biomedical [21], and naval, which this article focuses on. In this context, the studies conducted can be of a general nature, like those that will be analyzed in this review, but also very specific, addressing the impact of particular activities, such as the impact of fishing [22][23][24] and of fishing-specific fish species, such as tuna [25], bluefish [24,26,27], and others [28][29][30], through an LCA.…”

The naval sector holds paramount importance for the global economy, yet it entails significant environmental impacts throughout the entire life cycle of ships. This review explores the application of life-cycle assessment (LCA) in the naval sector, a methodology for evaluating the environmental impacts associated with all the life stages of a product or service. LCA analysis in the naval context is essential for identifying and mitigating environmental impacts, thus promoting more sustainable development of the sector. This work provides a comprehensive overview of current LCA applications in the naval sector, highlighting major environmental impacts, in particular focusing on greenhouse-gas emissions and climate change. Additionally, this study integrates an analysis of greenhouse-gas emissions using a normalization approach, which has enabled the comparison of various types of fuels and ships, thereby enhancing our understanding of their environmental impacts. Moreover, the limits and challenges to applying LCA in the naval sector are discussed, offering insights for future research and developments in the field. This review aims to raise awareness among policymakers, designers, and operators in the naval sector about the importance of adopting LCA for more sustainable and responsible management of naval activities, thereby contributing to the protection of the marine and global environment.

“…El análisis de ciclo de vida es una metodología ideal para establecer el impacto al medio ambiente generado por procesos de soldadura, que no involucran solamente materiales de aporte como electrodos, sino también el empleo de electricidad y la emisión de gases que afectan directamente a la capa de Ozono. Según Di Bella et al (2022), "el ACV evalúa e integra información en múltiples categorías de impacto, como el uso del agua, el cambio climático y el agotamiento del ozono, con consideraciones de impacto múltiple destinadas a evitar el cambio de carga (p. 127). Por lo antes señalado se puede establecer que la reducción en una categoría de impacto conduce a un aumento en otras categorías de impacto, sin importar el proceso evaluado.…”

Introducción: en la actualidad la soldadura es uno de los procesos de fabricación más importante en el sector manufacturero, pues une dos o más piezas mediante calentamiento o mediante procesos de fundición, aplicando o no presión. La finalidad de la fabricación por procesos de soldadura es unir materiales para que cumplan requisitos o necesidades de servicio sin que ello implique costo elevados, implicaciones negativas al medio ambiente o efectos adversos a los trabajadores. Es por ello que la evaluación del ciclo de vida (ACV) es una metodología que se aplican a nivel ingenieril para evaluar los distintos impactos ambientales de las tecnologías de soldadura, esta metodología ha sido aplicada en procesos de soldadura manual por arco metálico (MMAW), en donde el consumo excesivo de recursos como electrodos y energía necesaria para fundir los consumibles contribuyen a la generación de impactos ambientales negativos, siendo procesos potenciales de calentamiento global, de creación de ozono fotoquímico y eutrofización. Objetivo: investigar el avance en el estado del arte de las evaluaciones del ciclo de vida ambiental en procesos de soldadura MMAW. Resultados: los resultados del análisis de ciclo de vida ambiental indican que, para un cordón de soldadura de 1 metro de longitud mediante el proceso MMAW se consume mayor cantidad de recursos, como materiales de relleno y revestimientos de electrodos, además de un mayor consumo de energía eléctrica por parte de la máquina de soldar, lo que contribuye a impactos ambientales comparativamente mayores a los generados en otros procesos de soldadura. Conclusiones: se concluyó que la baja velocidad de soldadura y tasa alta de deposición conducen a tiempos elevados de soldadura en procesos MMAW, en consecuencia, la baja productividad y el exceso de recursos generan un mayor impacto al medio ambiente.
