Similarities and differences among half-marathon runners according to their performance level
(Public Library Science, 2018-01-24)
This study aimed to identify the similarities and differences among half-marathon runners in relation to their performance level. Forty-eight male runners were classified into 4 groups according to their performance level ...
Structural and Magnetic Properties of Ni0.8Fe0.2/Ti Nanoscale Multilayers
(MDPI, 2018-09-30)
The influence of the thickness of the Ni0.8Fe0.2 (Permalloy, Py) layers on the structural and magnetic properties of magnetron sputtered Py/Ti multilayers was studied. The thickness of the Py layers was varied in the ...
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 ...
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 ...
