A robot for non-destructive testing weld inspection of offshore mooring chains
(SAGE Publications Inc., 2018-05-09)
Welding flaw detection is a key step in manufacturing many components. In offshore chains, every link is manufactured from a steel bar that is bent and the ends joined by flash butt welding. Ultrasonic inspection of the ...
Correlación de modelos térmicos matemáticos de sistemas espaciales con ensayos térmicos mediante algoritmos genéticos.
(2018-04-06)
Las condiciones ambientales en el espacio exterior son muy extremas. Por ello cualquier equipo que es enviado al espacio cuenta con un sistema de control térmico (TCS) cuyo propósito es mantener los distintos componentes ...
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 ...
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 ...

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)
The emergence of multitasking machines in the machine tool sector presents new opportunities for the machining of large size gears and short production series in these machines. However, the possibility of using standard ...
Automatic Analysis of Archimedes’ Spiral for Characterization of Genetic Essential Tremor Based on Shannon’s Entropy and Fractal Dimension
(MDPI, 2018-07)
Among neural disorders related to movement, essential tremor has the highest prevalence; in fact, it is twenty times more common than Parkinson's disease. The drawing of the Archimedes' spiral is the gold standard test to ...
Study of the Influence of Shielding Gases on Laser Metal Deposition of Inconel 718 Superalloy
(MDPI, 2018-08)
The use of the Laser Metal Deposition (LMD) technology as a manufacturing and repairing technique in industrial sectors like the die and mold and aerospace is increasing within the last decades. Research carried out in the ...
