Mechatronic Model Based Jerk Optimization in Servodrives with Compliant Load
(Springer Nature Switzerland AG, 2018-08-02)
The aim of this work is to develop a mechatronic model for servodrives that move a compliant load, which is the case of large heavy machine tools. The model integrates the dynamics of the motor, transmission chain and ...
Evaluation of the Bond-to-Concrete Properties of GFRP Rebars in Marine Environments
(MDPI, 2018-10-08)
Increased traffic in combination with growing environmental impacts have led to the accelerated degradation of built infrastructure. In reinforced concrete structures, the corrosion of steel reinforcement is the predominant ...
A robot for welding inspection in offshore mooring chains
(Springer, 2018-08-31)
In this paper, the authors present the CIRUS robot. This automatic system uses a combination of pulse-echo and pitch and catch ultrasonic strategies for the inspection of the welded area of mooring chain links in an automatic ...
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 ...
Interfaces tecnológicos corporales en la práctica artística de María Castellanos
(Universidade de Lisboa, 2018-03)
Este artículo se centrará en tres proyectos realizados por la artista María Castellanos (Gijón 1985) en colaboración con el matemático Alberto Valverde. De esta obra, que trata la figura del cíborg, se describen los ...
Adaptive Sliding Mode Control for a Double Fed Induction Generator Used in an Oscillating Water Column System
(MDPI, 2018-10-27)
Wave power conversion systems are nonlinear dynamical systems that must endure strong uncertainties. Efficiency is a key issue for these systems, and the application of robust control algorithms can improve it considerably. ...
A Nonlinear Autoregressive Exogenous (NARX) Neural Network Model for the Prediction of the Daily Direct Solar Radiation
(MDPI, 2018-03)
The solar photovoltaic (PV) energy has an important place among the renewable energy sources. Therefore, several researchers have been interested by its modelling and its prediction, in order to improve the management of ...
Linear and Nonlinear Causality between Energy Consumption and Economic Growth: the Case of Mexico 1965-2014
(MDPI, 2018-03-29)
This paper analyzes the causal link between aggregated and disaggregated levels of energy consumption and economic growth in Mexico between 1965 and 2014, with the presence of structural breaks stemming from the series. ...
UrdA Controls Secondary Metabolite Production and the Balance between Asexual and Sexual Development in Aspergillus Nidulans
(MDPI, 2018-11-23)
The genus Aspergillus includes important plant pathogens, opportunistic human pathogens and mycotoxigenic fungi. In these organisms, secondary metabolism and morphogenesis are subject to a complex genetic regulation. Here ...
Modification of Pea Starch and Dextrin Polymers with Isocyanate Functional Groups
(MDPI, 2018-09)
Pea starch and dextrin polymers were modified through the unequal reactivity of isocyanate groups in isophorone diisocyanate (IPDI) monomer. The presence of both urethane and isocyanate functionalities in starch and dextrin ...
