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 ...
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 ...
Entrepreneurs' perceptions of their entrepreneurial process: a qualitative analysis of in-depth interviews with Education graduates in the Basque Country, Spain
(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 ...
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 ...
Uncertainty Analysis of Two Gas Measurement DGA Ratios for Improved Diagnostics Applications
(IEEE, 2022)
This paper formulates the exact analytical probability density function (PDF) for the ratio of two independent dissolved gas analysis (DGA) measurements that include individual gas measurement errors. It is demonstrated ...
Impacto del factor comunitario (factor C) sobre el funcionamiento y resultados de empresas sociales de servicios sanitarios rurales
(Mondragon Unibertsitatea. Enpresagintza Fakultatea, 2022)
El Factor C fue definido en el marco de la Teoría Económica Comprensiva como aquella
energía social que surge de la unidad de conciencias, sentimientos y voluntades de un
grupo, tras un objetivo compartido (Razeto, 2017). ...
Reflection through Diffraction: Interdisciplinarity in Energy Science
(Addleton Academic Publishers, 2022)
To address the complexities associated with transitioning towards sustainable energy solutions, there are increasing demands to employ interdisciplinary approaches. However, these still represent a minority of research ...
Multi-Objective Metamorphic Test Case Selection: an Industrial Case Study (Practical Experience Report)
(IEEE, 2022)
Metamorphic testing is a technique that has shown great potential to alleviate the test oracle problem by exploiting the relations among the inputs and outputs of different executions of a system. However, this approach ...
Pattern selection for convective flow in a liquid bridge subjected to remote thermal action
(AIP Publishing, 2022)
The stability of thermocapillary/buoyant flows is affected by a remote thermal source. We present a nonlinear two-phase computational study of convection in a liquid bridge that develops under the action of Marangoni and ...
UX-for Smart-PSS: Towards a Context-Aware Framework
(SCITEPRESS, 2022)
Smart-product service systems are a business strategy that combines product and service into one value proposition. The user experience of digital services and the smart product can be a clear differentiator among competitors ...
High-Frequency Modelling of Windings
(IEEE, 2022)
Electrical drives consume a great amount of the world’s energy, and this will keep increasing due to the electromobility trend. Hence, the efficiency of electrical drives must be improved to reach sustainability. Silicon ...
Modular battery energy storage system design factors analysis to improve battery-pack reliability
(Elsevier, 2022)
Traditional battery energy storage systems (BESS) are based on the series/parallel connections of big amounts of cells. However, as the cell to cell imbalances tend to rise over time, the cycle life of the battery-pack is ...
