A dynamic data driven application system for real-time simulation of resin transfer moulding processes
(Springer, 2022)
[EN] This paper presents a numerical solution to optimize RTM processes based on a DDDAS methodology, taking permeability as stochastic. The model proposed in this investigation allows real-time accurate prediction of the ...
Performance of Optimization Algorithms in the Model Fitting of the Multi-Scale Numerical Simulation of Ductile Iron Solidification
(MDPI, 2020-08-08)
The use of optimization algorithms to adjust the numerical models with experimental values has been applied in other fields, but the efforts done in metal casting sector are much more limited. The advances in this area may ...
Metamodels’ Development for High Pressure Die Casting of Aluminum Alloy
(MDPI, 2021-10-31)
Simulation is a very useful tool in the design of the part and process conditions of high-pressure die casting (HPDC), due to the intrinsic complexity of this manufacturing process. Usually, physics-based models solved by ...
A Rubric to Assess and Improve Technical Writing in Undergraduate Engineering Courses
(MDPI, 2021-03-24)
Although there is consensus in the literature that writing skills are important in STEM (Science, Technology, Engineering, and Mathematics) studies, they are often neglected. However, some efforts have been made to correct ...
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 ...
