Behavior of NiTi wires for dampers and actuators in extreme conditions
(2015-09-01)
Article
Open AccessShape memory alloys are considered smart materials because of their singular thermo-mechanical properties, due to a thermoelastic martensitic transformation, enabling possible uses as actuators (because of mechanical ... -
Availability of crop by-products in Spain: new raw materials for natural thermal insulation
(2015-06-01)
Article
Open AccessVegetal materials were one of the first construction materials used by humans, but the development of petrol-based synthetic materials in the last century replaced them in mainstream construction techniques. However, since ... -
DA white dwarfs from the LSS-GAC survey DR1: the preliminary luminosity and mass functions and formation rate
(2015-06-11)
Article
Open AccessModern large-scale surveys have allowed the identification of large numbers of white dwarfs. However, these surveys are subject to complicated target selection algorithms, which make it almost impossible to quantify to ... -
Aftershock sequences of three seismic crises at southern California, USA, simulated by a cellular automata model based on self-organized criticality
(2015-03-01)
Article
Restricted access - confidentiality agreementSeveral properties of aftershock series related to the main shocks of Landers, Northridge and Hector Mine (southern California, USA) are reproduced by the Dynamic Fiber Bundle Model, DFBM. Optimum values for the three ... -
Montaje experimental para el estudio de la mezcla generada por penachos turbulentos
(Universidad Complutense de Madrid (UCM), 2009-09-01)
Article
Open AccessSe presenta un sencillo modelo de laboratorio para generar mezcla turbulenta entre dos fluidos miscibles que están en una situación inicial inestable en un campo gravitatorio. El proceso de mezcla se genera por medio de ... -
Amorphous carbon modified nano-sized tungsten carbide as a gas diffusion electrode catalyst for the oxygen reduction reaction
(2015-01-01)
Article
Open AccessNanostructured tungsten carbide with high surface area and containing amorphous carbon is prepared by a low temperature combustion synthesis method. The nanostructured tungsten carbide is used as the catalyst in a gas ... -
Lifted temperature minimum during the atmospheric evening transition
(2015-06-29)
Article
Open AccessObservations of lifted temperature minimum (LTM) profiles in the nocturnal boundary layer were first reported in 1932. It was defined by the existence of a temperature minimum some centimetres above the ground. During the ... -
Turbulence vertical structure of the boundary layer during the afternoon transition
(2015-09-09)
Article
Open AccessWe investigate the decay of planetary boundary layer (PBL) turbulence in the afternoon, from the time the surface buoyancy flux starts to decrease until sunset. Dense observations of mean and turbulent parameters ... -
Experimental study of heat transport in fractured network
(2015-07-01)
Article
Open AccessFractured rocks play an important role in transport of natural resources through subsurface systems. In recent years, interest has grown in investigating heat transport by means of tracer tests, driven by the important ... -
Continuation of bifurcations of periodic orbits for large-scale systems
(2015-01-01)
Article
Open AccessA methodology to track bifurcations of periodic orbits in large-scale dissipative systems depending on two parameters is presented. It is based on the application of iterative Newton-Krylov techniques to extended systems. ... -
Numerical continuation in classical mechanics and thermodynamics
(2015-01-01)
Article
Open AccessIn this paper, modern numerical continuation methodologies are presented as a way of understanding and computing multiplicity of solutions in undergraduate physics problems. Mechanical and thermodynamical problems are used ... -
Onshore sandbar migration in the surf zone: new insights into the wave-induced sediment transport mechanisms
(2015-04-28)
Article
Open AccessWe present a novel process-based morphodynamic model, which includes transport processes due to both velocity and acceleration skewness and a new formulation for intrawave motions, that successfully simulates observations ...
