The Faculty of Engineering in Applied Sciences at Universidad Técnica del Norte presents Volume 6, Issue 2 of its scientific journal: Innovation & Development in Engineering and Applied Science – IDEAS, titled: Diverse Axes in Multidisciplinary Engineering Applications. This edition comprises ten high-level articles addressing areas such as textile engineering, industrial engineering, energy, educational technology, bioengineering, and economic engineering.

Omar Godoy, from Universidad Técnica del Norte, stands out in the textile field with a literature review on cotton dyeing, emphasizing the importance of proper selection of dyes and auxiliaries to maximize process efficiency and sustainability. Complementing this approach, Chamorro et al., from the same university and in collaboration with Instituto Superior Tecnológico Tena, present a study on the production of non-woven wool, offering innovative methods for fiber homogenization and compaction. In the field of energy design, Benavides et al. demonstrate a tool for optimizing the performance of centrifugal pumps used as turbines through advanced numerical simulations and computational fluid dynamics (CFD) analysis. This approach provides valuable insights into the efficiency and operational characteristics of the pump-turbine system.

Tapia and Galvis, from Universidad Politécnica Estatal del Carchi, enrich the realm of sustainable solutions and agriculture with a study combining ARIMA methods, Bayesian optimization, and XGBoost models to predict rainfall. This robust tool enhances agricultural resilience to meteorological variations. Cerrón et al., from the Digital Fabrication Laboratory at Universidad Continental and Universidad Católica de Santa María in Peru, address education during the pandemic by adapting the "Ruta Maker" program to a virtual environment. This study shows that digital learning ecosystems can significantly strengthen students' technological skills and maker culture. Additionally, Araujo et al., from Instituto Superior Tecnológico ITCA, implement augmented reality in education, demonstrating notable improvements in information retention and comprehension.

In the field of biotechnology and renewable natural resources, León et al. present an innovative proposal for an Intelligent Aerial Laboratory (IAL) to monitor water sources using unmanned aerial vehicles. This advanced solution enables remote and autonomous surveillance of water bodies. On the other hand, Benalcázar and Pinto, from Universidad Técnica del Norte, present a matrix metric for evaluating learning in Complex Mathematics, providing an effective tool for identifying and improving areas with opportunities for growth in basic sciences knowledge. Astudillo et al., from Instituto Superior Tecnológico Universitario San Isidro, offer an economic analysis of the activities generated around a unique temporary event and its influence on the entrepreneurial sector's economy. Finally, Parra et al., from Instituto Universitario Misael Acosta, develop a mobile panic button application, under the SCRUM methodology, that enhances security and communication in emergency situations in rural communities.

The contributions achieved with this collection of studies offer innovative and practical solutions to contemporary challenges in multidisciplinary engineering, promoting sustainability, efficiency, and continuous improvement in various industrial and academic sectors. The diversity of research reflects IDEAS journal's commitment to disseminating knowledge that contributes to scientific and technological advancement in Ecuador and internationally.
