Lessons, narratives, and research directions for a sustainable circular economy
(Wiley, 2022)The current enthusiasm for the circular economy (CE) offers a unique opportunity to advance the impact of research on sustainability transitions. Diverse interpretations of CE by scholars, however, produce partly opposing ... -
Friction Modelling for Tube Hydroforming Processes : A Numerical and Experimental Study with Different Viscosity Lubricants
(MDPI, 2022)The final quality of sheet and tube metal–formed components strongly depends on the tribology and friction conditions between the tools and the material to be formed. Furthermore, it has been recently demonstrated that ... -
Evaluation of User Experience in Human–Robot Interaction : A Systematic Literature Review
(Springer, 2023)Industry 4.0 has ushered in a new era of process automation, thus redefining the role of people and altering existing workplaces into unknown formats. The number of robots in the manufacturing industry has been steadily ... -
A novel indirect cryogenic cooling system for improving surface finish and reducing cutting forces when turning ASTM F-1537 cobalt-chromium alloys
(Springer, 2020)This paper presents a novel indirect cryogenic cooling system, employing liquid nitrogen (LN2) as a coolant for machining the difficult-to-cut ASTM F-1537 cobalt-chromium (CoCr) alloy. The prototype differs from the already ... -
Improving surface integrity when drilling CFRPs and Ti-6Al-4V using sustainable lubricated liquid carbon dioxide
(Elsevier, 2022)In the quest for decreasing fuel consumption and resulting gas emissions in the aeronautic sector, lightweight materials such as Carbon Fiber Reinforced Polymers (CFRPs) and Ti-6Al-4V alloys are being used. These materials, ... -
Design Space Analysis of the Dual-Active-Bridge Converter for More Electric Aircraft
(MDPI, 2022)In the literature, different DC/DC power electronic converters (PECs) have been found to interconnect high-voltage DC and low-voltage DC grids in the electric power distribution networks of aircraft. In this scenario, the ... -
Spatial characterization of the effect of age and sex on macular layer thicknesses and foveal pit morphology
(PLoS, 2022)Characterizing the effect of age and sex on macular retinal layer thicknesses and foveal pit morphology is crucial to differentiating between natural and disease-related changes. We applied advanced image analysis techniques ... -
Adiabatic self-heating determination for Ti6Al4V at different temperatures
(Elsevier, 2023)Nowadays, numerical models are one of the most widely used techniques to predict material performance subjected to different manufacturing processes. However, to obtain accurate predictions, these models require reliable ... -
Spirituality infrastructure: Notes for Analysing Arantzazu’s Ecosystem
(Sinnergiak Social Innovation, 2022-12-29)This article sets out to approach spirituality as cultural substratum in the enclave of the Arantzazu Sanctuary (Gipuzkoa, Basque Country) through the counterintuitive notion of infrastructure. Through four vastly different ... -
The paradox of the basque farmhouse: The enfolding and unfolding of a cultural infrastructure
(Sinnergiak Social Innovation, 2022-12-29)This article addresses some of the interpretations that have consolidated the cultural- symbolic-cultural imaginary of the Basque farmhouse, and then broadens the form of approaching the narrative of its identity. From the ... -
Some Seeds are Strong : Seeding Strategies for Search-based Test Case Selection
(ACM, 2022)The time it takes software systems to be tested is usually long. Search-based test selection has been a widely investigated technique to optimize the testing process. In this paper, we propose a set of seeding strategies ... -
Uncertainty-aware Robustness Assessment of Industrial Elevator Systems
(ACM, 2022)Industrial elevator systems are commonly used software systems in our daily lives, which operate in uncertain environments such as unpredictable passenger traffic, uncertain passenger attributes and behaviors, and hardware ... -

(InderScience, 2022)Entrepreneurship is necessary for the economic development of societies. Universities play a key role in this process by fostering entrepreneurship and promoting entrepreneurial skills. Studies show that entrepreneurship ... -
Determination of the molecular diffusion coefficients in ternary mixtures by the sliding symmetric tubes technique
(AIP Publishing, 2014)A new analytical methodology has been developed to determine the diagonal and cross-diagonal molecular diffusion coefficients in ternary mixtures by the Sliding Symmetric Tubes technique. The analytical solution is tested ... -
Low delay network attributes randomization to proactively mitigate reconnaissance attacks in industrial control systems
(Springer, 2023)Industrial Control Systems are used in a wide variety of industrial facilities, including critical infrastructures, becoming the main target of multiple security attacks. A malicious and successful attack against these ... -
Spectrum-based feature localization for families of systems
(Elsevier, 2022)In large code bases, locating the elements that implement concrete features of a system is challenging. This information is paramount for maintenance and evolution tasks, although not always explicitly available. In this ... -
Data‐Driven Low‐Frequency Oscillation Event Detection Strategy for Railway Electrification Networks
(MDPI, 2023)Low-frequency oscillations (LFO) occur in railway electrification systems due to the incorporation of new trains with switching converters. As a result, the increased harmonic content can cause catenary stability problems ...
