Analysis of University STEM Students’ Mathematical, Linguistic, Rhetorical–Organizational Assignment Errors
(MDPI, 2021-04-06)
Although Error Analysis (EA) has been broadly used in Foreign Language and Mother Tongue learning contexts, it has not been applied in the field of engineering and by STEM (Science, Technology, Engineering, and Mathematics) ...
A Functional Data Analysis for Assessing the Impact of a Retrofitting in the Energy Performance of a Building
(MDPI, 2020-04-07)
There is an increasing interest in reducing the energy consumption in buildings and in improving their energy efficiency. Building retrofitting is the employed solution for enhancing the energy efficiency in existing ...
Structural Health Monitoring Using Ultrasonic Guided-Waves and the Degree of Health Index
(MDPI, 2021-02-02)
This paper proposes a new damage index named degree of health (DoH) to efficiently tackle structural damage monitoring in real-time. As a key contribution, the proposed index relies on a pattern matching methodology that ...
Improvement of boring operations by means of mode coupling effect
(Elsevier, 2022-05)
Boring bars are inherently slender tools which are prone to show chatter problems due to their low dynamic stiffness and damping, being this problem their main limitation in productivity. The onset of chatter is mainly ...
Improvement of Shape Error for Slender Parts in Cylindrical Traverse Grinding by Part-Deformation Modelling and Compensation
(MDPI, 2021-12-09)
Achieving geometrical accuracy in cylindrical traverse grinding for high-aspect slender parts is still a challenge due to the flexibility of the workpiece and, therefore, the resulting shape error. This causes a bottleneck ...
On the Analysis of Speech and Disfluencies for Automatic Detection of Mild Cognitive Impairment
(Springer, 2020-10)
Alzheimer's disease is characterized by a progressive and irreversible cognitive deterioration. In a previous stage, the so-called Mild Cognitive Impairment or cognitive loss appears. Nevertheless, this previous stage does ...
Conceiving a Digital Twin for a Flexible Manufacturing System
(MDPI, 2022-09-30)
Digitization and virtualization represent key factors in the era of Industry 4.0. Digital twins (DT) can certainly contribute to increasing the efficiency of various productive sectors as they can contribute to monitoring, ...
Influence of Elastomer Layers in the Quality of Aluminum Parts on Finishing Operations
(MDPI, 2020-02-22)
In finishing processes, the quality of aluminum parts is mostly influenced by static and dynamic phenomena. Different solutions have been studied toward a stable milling process attainment. However, the improvements obtained ...
Fatigue improvement and residual stress relaxation of shot-peened alloy steel DIN 34CrNiMo6 under axial loading
(Elsevier, 2022-09)
Shot-peening treatment was applied to a quenched and tempered DIN 34CrNiMo6 steel to improve its high-cycle R: -1 axial fatigue strength. Compared with the machined condition, the increase in the fatigue limit was 21.8%. ...
Desarrollo de un sistema de monitorización y control para el proceso de aporte metálico por láser basado en la digitalización tridimensional de la geometría
(2021-09-15)
El principal objetivo de esta tesis es desarrollar una metodología robusta de monitorización y control del proceso de aporte, Laser Metal Deposition (LMD), que permita reducir el tiempo y coste de fabricación y aumente la ...
