La Nueva Realidad Laboral y Empresarial. Los Nuevos Prestadores de Servicios y las Nuevas Tecnologías, Robotización, Digitalización, Inteligencia Art…
2018
Actualmente, la nueva realidad laboral y empresarial y los nuevos prestadores de servicios y las nuevas tecnologías, robotización, digitalización, inteligencia artificial han hecho que el ámbito de las relaciones laborales haya quedado trastocado dejando sin cobertura y en desprotección a un gran número de colectivos que prestan sus servicios mediante plataformas digitales y nuevas modalidades empresariales.
 La delimitación de las nuevas categorías de trabajadores impide la protección por el derecho del trabajo clásico, quedando éste, en entredicho, permitiendo el trabajo sin la cobertura del derecho laboral a un gran colectivo de trabajadores que prestan sus servicios de forma muy pr…
EFECTOS DE LOS VIDEOJUEGOS EN LAS MARCAS EMPLAZADAS: LA TRANSMISIÓN DE EMOCIONES
2012
RESUMENDebido a que los medios tradicionales están saturados de mensajes publicitarios, las organizaciones buscan nuevos formatos de comunicación. Uno de ellos es el product placement en videojuegos. En esta investigación exploratoria se van a analizar las consecuencias de emplazar una marca en esta forma de ocio electrónico en cuanto a transferencia de imagen del videojuego a la marca a través de las emociones evocadas por el videojuego. Para tal fin, en el presente trabajo se desarrolla una escala de emociones adaptada al tema que ocupa esta investigación. Del mismo modo, se analizan las diferencias entre los tipos de product placement y sus efectos en la transferencia de imagen videojueg…
Systematic Assessment of MODTRAN Emulators for Atmospheric Correction
2021
Atmospheric radiative transfer models (RTMs) simulate the light propagation in the Earth's atmosphere. With the evolution of RTMs, their increase in complexity makes them impractical in routine processing such as atmospheric correction. To overcome their computational burden, standard practice is to interpolate a multidimensional lookup table (LUT) of prestored simulations. However, accurate interpolation relies on large LUTs, which still implies large computation times for their generation and interpolation. In recent years, emulation has been proposed as an alternative to LUT interpolation. Emulation approximates the RTM outputs by a statistical regression model trained with a low number …
Approximating Empirical Surface Reflectance Data through Emulation: Opportunities for Synthetic Scene Generation
2019
Collection of spectroradiometric measurements with associated biophysical variables is an essential part of the development and validation of optical remote sensing vegetation products. However, their quality can only be assessed in the subsequent analysis, and often there is a need for collecting extra data, e.g., to fill in gaps. To generate empirical-like surface reflectance data of vegetated surfaces, we propose to exploit emulation, i.e., reconstruction of spectral measurements through statistical learning. We evaluated emulation against classical interpolation methods using an empirical field dataset with associated hyperspectral spaceborne CHRIS and airborne HyMap reflectance spectra…
Linear spectral mixture modelling to estimate vegetation amount from optical spectral data
1996
Abstract Spectral mixture modelling has developed in recent years as a suitable remote sensing tool for analysing the biophysical and compositional character of ground surfaces. In this paper the potentiality of the linear spectral mixture model to extract vegetation related parameters from 0·4-2·5 μm reflectance data has been tested. High spectral resolution reflectance measurements of soil-plant mixtures with different soil colour and plant densities were carried out in a laboratory experiment. The constrained least-squares and the factor analysis unmixing procedures were applied to generate endmember fractions of the components present in the mixtures and to test the validity of the mode…
The Role of re-design for Additive Manufacturing on the Process Environmental Performance
2018
Abstract At present, economic and technological design criteria for products and processes should be matched with the minimization of environmental impact objectives. Manufacturing, material production, and product design are strictly connected stages. The choice of a production system over another could result in significant material and energy/resource savings, particularly if the component has been properly designed for manufacturing. In this scenario, Additive Manufacturing, which has been identified as a potential disruptive technology, gained an increasing interest for the creation of complex metal parts. The paper focuses on the tools, based on the holistic modelling of additive and …

Decision-making Tool for Moving from 3-axes to 5-axes CNC Machine-tool
2016
Abstract Nowadays most of the parts within machine-building industry are machines on CNC machine-tools. According to their mechanical and kinematic structure, CNC machine-tools can be divided into 3-axes and 5-axes ones. Each type has its advantages and drawbacks and choosing between them could be a very difficult process. This paper presents a decision support tool for aiding the process of selecting between using and/or buying either a 3-axes CNC milling machine or a 5-axes milling machine, based upon fuzzy logic. The tool was built using the Fuzzy Logic Toolbox and the fuzzy graphical user interface (GUI) within Matlab software package.

Farm Cultural Park : An Experience of Social Innovation in the Recovery of the Historical Centre of Favara
2017
In 2010 some people from Favara decided to initiate a process of recovery and re-appropriation of the abandoned historical centre, by establishing Farm Cultural Park, a private cultural institution. This paper aims to describe the process of sustainable design, social innovation and inclusion, triggered by the Farm Cultural Park in the historical centre of Favara which, by showing its resilience, has redefined its identity, progressing from a place of widespread, unauthorised development to a dynamic creative city.
