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 ...
An Analysis of Electroplated cBN Grinding Wheel Wear and Conditioning during Creep Feed Grinding of Aeronautical Alloys
(MDPI, 2018-05-14)
Cubic boron nitride (cBN), in addition to diamond, is one of the two superabrasives most commonly used for grinding hard materials such as ceramics or difficult-to-cut metal alloys such as nickel-based aeronautical alloys. ...
A Consistent Procedure Using Response Surface Methodology to Identify Stiffness Properties of Connections in Machine Tools
(MDPI, 2018-07)
Accurate finite element models of mechanical systems are fundamental resources to perform structural analyses at the design stage. However, uncertainties in material properties, boundary conditions, or connections give ...
Spiral Bevel Gears Face Roughness Prediction Produced by CNC End Milling Centers
(MDPI, 2018-08)
