Emulation of 2D Hydrodynamic Flood Simulations at Catchment Scale Using ANN and SVR
2021
Two-dimensional (2D) hydrodynamic models are one of the most widely used tools for flood modeling practices and risk estimation. The 2D models provide accurate results
Robotic Platform for Automated Search and Rescue Missions of Humans
2013
We present a novel type of model incorporating a special remote life signals sensing optical system on top of a controllable robotic platform. The remote sensing system consists of a laser and a camera. By properly adapting our optics and by applying a proper image processing algorithm we can sense within the field of view, illuminated by the laser and imaged by the camera, the heartbeats and the blood pulse pressure of subjects (even several simultaneously). The task is to use the developed robotic system for search and rescue mission such as saving survivals from a fire.
Contact Estimation in Robot Interaction
2014
In the paper, safety issues are examined in a scenario in which a robot manipulator and a human perform the same task in the same workspace. During the task execution, the human should be able to physically interact with the robot, and in this case an estimation algorithm for both interaction forces and a contact point is proposed in order to guarantee safety conditions. The method, starting from residual joint torque estimation, allows both direct and adaptive computation of the contact point and force, based on a principle of equivalence of the contact forces. At the same time, all the unintended contacts must be avoided, and a suitable post-collision strategy is considered to move the r…
¿Cómo funciona el sistema de innovación del sector cerámico español?
2013
[EN]: In this article we apply the functions of innovation systems framework to assess its appropriateness to characterise the innovation activity of the tile industry in Castellón. This framework is based on idea that a well functioning innovation system requires that a number of key activities take place. If this occurs innovative output is higher. Our analysis provides a deeper understanding of the role of innovation as a strategic option in a mature industry in the context of globalisation. By applying this new theoretical approach to study innovation and highlighting the functions that the system requires, we shown the constraints, inertias, challenges and opportunities that the innova…

¿Proveer justicia u oprimir a los pueblos? La acción de los corregedores de las Azores en el periodo moderno
2020
En Portugal, los corregedores han sido presentados por la historiografía tradicional como uno de los pilares del proceso de centralización política que había tenido lugar en el reino portugués a partir del final de la Edad Media. Esta interpretación ha sido corregida en las últimas décadas por nuevas investigaciones e interpretaciones. En los territorios portu- gueses de ultramar, la distancia amplió algunos de los “obstáculos fácticos” (según Antonio Manuel Hespanha) que hacían difícil, si no imposible, la concreción de cualquier proyecto centralizador. El caso azoriano es de esto un buen ejemplo. En este artículo, además de una síntesis de los poderes de los corregedores…
Physicochemical and functional characterization of the polymerization process of the Geodia cydonium lectin
1985
The extracellularly localized, galactose-specific lectin from the sponge Geodia cydonium binds at one class of sites, 40 mol Ca2+/mol lectin with an association constant (Ka) of 0.3 X 10(6)M-1. Stoichiometric calculations reveal that in the extracellular milieu 22 mol Ca2+ (maximum) are complexed per mol lectin. Binding of Ca2+ to the lectin increases its apparent Mr from 44000 to 56000 (electrophoretic determination) or from 36500 to 53500 (high-pressure liquid gel chromatographical determination); the s20, w increases from 4.3 S to 4.5 S if Ca2+ is added to the lectin. In the presence of Ca2+ the lectin undergoes a conformational change perhaps by expanding the carbohydrate side chains wh…
Olleros, alfareros y fabricantes de loza en Ribesalbes, entre 1742 y 1817
2012
El desarrollo de la tradición alfarera en Ribesalbes, y el posterior establecimiento de las primeras fábricas de loza, a finales del siglo XVIII, viene determinado por los condicionantes naturales e históricos de la villa; así como por la influencia decisiva de la Real Manufactura del conde de Aranda, en la vecina población de L’Alcora. En este trabajo, a partir de diversas fuentes documentales primarias, entre las que cabe destacar los libros sacramentales del Archivo Parroquial de Ribesalbes, y la Contribución general de 1817, se constata la presencia de olleros en la Baronía, a principios del siglo XVIII. Se determinan también los nombres de algunos alfareros, registrados en los albores …
Modeling of Melt Flow and Heat Transfer in Stationary Gas Tungsten Arc Welding with Vertical and Tilted Torches
2021
A 3D numerical simulation was conducted to study the transient development of temperature distribution in stationary gas tungsten arc welding with filler wire. Heat transfer to the filler wire and the workpiece was investigated with vertical (90°) and titled (70°) torches. Heat flux, current flux, and gas drag force were calculated from the steady-state simulation of the arc. The temperature in the filler wire was determined at three different time intervals: 0.12 s, 0.24 s, and 0.36 s. The filler wire was assumed not to deform during this short time, and was therefore simulated as solid. The temperature in the workpiece was calculated at the same intervals using heat flux, current flux, ga…
