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 ...
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 ...
Framework for the Shape Optimization of Aerodynamic Profiles Using Genetic Algorithms
(Hindawi Publishing Corporation, 2013)
This study developed a framework for the shape optimization of aerodynamics profiles using computational fluid dynamics (CFD) and genetic algorithms. Agenetic algorithm code and a commercial CFD code were integrated to ...
A Methodology to Evaluate the Reliability Impact of the Replacement of Welded Components by Additive Manufacturing Spare Parts
(MDPI, 2019-08-26)
This article shows a method for inspection scheduling of structures made by additive manufacturing, derived from reliability function evaluations and overhaul inspection findings. The routine was an adaption of an existing ...
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 ...
Eraikuntza sektoreko enpresen berrikuntza maila neurtzeko modelo baten garapena
(2017-03-24)
Eraikuntza sektorea ez da bere errendimendu berritzaileagatik bereizten eta historikoki bere eraginkortasun-ezagatik kritikatua izan da. Horrez gain, gaur egungo krisi-ondorengo eszenatoki zailak ehun produktiboaren eta ...
Translational parallel manipulator with Pa2 kinematic joints
(Springer, 2016-10-01)
The kinematic pair Pa2 is composed of two interlinked parallelograms. It has two degrees of freedom that generate a translational plane variable with position. It has a structure different from the PaPa pair, which is ...
Virtual Sensor for Kinematic Estimation of Flexible Links in Parallel Robots
(MDPI, 2017-09)
The control of flexible link parallel manipulators is still an open area of research, endpoint trajectory tracking being one of the main challenges in this type of robot. The flexibility and deformations of the limbs make ...
High-Temperature Mechanical Properties of IN718 Alloy: Comparison of Additive Manufactured and Wrought Samples
(MDPI, 2020-08-09)
Wire Arc Additive Manufacturing (WAAM) is one of the most appropriate additive manufacturing techniques for producing large-scale metal components with a high deposition rate and low cost. Recently, the manufacture of ...
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 ...
