(Universidad Complutense de Madrid, 2019-02-18)El objetivo principal de este trabajo de investigación es conocer las percepciones y expectativas de las personas trabajadoras de una cooperativa del Grupo MONDRAGON sobre la comunicación interna. Se ha puesto especial ... -
Indicadores necesarios para diseñar un dashboard desde la perspectiva de los profesores: un estudio cualitativo
(Organización de Estados Iberoamericanos, 2019-05-14)El número de estudiantes matriculados en cursos online de educación superior está aumentando, y como resultado, se generan más datos sobre su proceso de aprendizaje. Los datos generados pueden ser mostrados en un dashboard ... -
Towards the automation of the die spotting process: Contact blue pattern decryption
(Elsevier Ltd., 2020)Automotive die spotting is one of the most complex and least standardized processes in the tool making process. A spotting expert identifies local contact areas through a blue-paste pattern and the die/sheet contact is ... -
Systematic complexity reduction of wave-to-wire models for wave energy system design
(Elsevier Ltd., 2020)Wave-to-wire models are valuable tools for a variety of applications in the development of successful wave energy converters. However, computational requirements of these wave-to-wire models are often prohibitive for certain ... -
Better to Be Alone than in Bad Company: Cognate Synonyms Impair Word Learning
(MDPI, 2020-07-29)The effects of cognate synonymy in L2 word learning are explored. Participants learned the names of well-known concrete concepts in a new fictional language following a picture-word association paradigm. Half of the ... -
Optical Dual Laser Based Sensor Denoising for OnlineMetal Sheet Flatness Measurement Using Hermite Interpolation
(MDPI AG, 2020)Flatness sensors are required for quality control of metal sheets obtained from steel coils by roller leveling and cutting systems. This article presents an innovative system for real-time robust surface estimation of ... -
A Diagnostics Framework for Underground Power Cables Lifetime Estimation Under Uncertainty
(IEEE, 2020)Power cables are critical assets for the reliable operation of the grid. The cable lifetime is generally estimated from the conductor temperature and associated lifetime reduction. However, these tasks are intricate due ... -
Case Study of the Experience Capturer Evaluation Tool in the Design Process of an Industrial HMI
(MDPI AG, 2020)In the absence of user experience evaluation tools for industrial human–machine interfaces (HMI), a specific tool called eXperience Capturer (XC) has been created. It is a multi-method user-centred tool that evaluates the ... -
A review of the effects of cyclic contact loading on fretting fatigue behaviour
(Sage Publishing Ltd., 2020)A damage phenomenon called fretting fatigue frequently takes place when two contact bodies are clamped together under a normal contact load along with a small-scale oscillatory motion due to cyclic loading. In contrast to ... -
Broaching: Cutting tools and machine tools for manufacturing high quality features in components
(Elsevier Ltd., 2020)Broaching is a unique machining process with high accuracy and surface quality, which is employed in massand batch production for the manufacture of components with highly complex geometries. It involves the use of ... -
The contribution of microstructure and friction in broaching Ferrite–Pearlite steels
(Elsevier Ltd., 2020)Ferrite-Pearlite (FP) steels are used in many automotive components. However, their machinability in low cutting speed processes appears to be highly dependent on their metallurgical state. An experimental approach combining ... -
