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 ...
Using nodal coordinates as variables for the dimensional synthesis of mechanisms
(Springer, 2018-06)
The method of the lower deformation energy has been successfully used for the synthesis of mechanisms for quite a while. It has shown to be a versatile, yet powerful method for assisting in the design of mechanisms. Until ...
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) ...
Performance of Gradient-Based Solutions versus Genetic Algorithms in the Correlation of Thermal Mathematical Models of Spacecrafts
(Hindawi, 2017)
The correlation of the thermalmathematical models (TMMs) of spacecrafts with the results of the thermal test is a demanding task in terms of time and effort. Theoretically, it can be automatized by means of optimization ...
An efficient LDU algorithm for the minimal least squares solution of linear systems
(Elsevier, 2018-12-15)
The minimal least squares solutions is a topic of interest due to the broad range of applications of this problem. Although it can be obtained from other algorithms, such as the Singular Value Decomposition (SVD) or the ...
Insights into mechanism kinematics for protein motion simulation
(Biomed Central, 2014-06-12)
Background: The high demanding computational requirements necessary to carry out protein motion simulations make it difficult to obtain information related to protein motion. On the one hand, molecular dynamics simulation ...
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 ...
