Detecting Functional Requirements Inconsistencies within Multi-teams Projects Framed into a Model-based Web Methodology
One of the most essential processes within the software project life cycle is the REP (Requirements
Engineering Process) because it allows specifying the software product requirements. This specification
should be as consistent as possible because it allows estimating in a suitable manner the effort required to
obtain the final product. REP is complex in itself, but this complexity is greatly increased in big, distributed
and heterogeneous projects with multiple analyst teams and high integration between functional modules.
This paper presents an approach for the systematic conciliation of functional requirements in big projects
dealing with a web model-based approach and how this approach may be implemented in the context of the
NDT (Navigational Development Techniques): a web methodology. This paper also describes the empirical
evaluation in the CALIPSOneo project by analyzing the improvements obtained with our approach.Ministerio de Economía y Competitividad TIN2013-46928-C3-3-RMinisterio de Economía y Competitividad TIN2015-71938-RED
An Extension of NDT to Model Entity Reconciliation Problems
Within the development of software systems, the development of web applications may be one of the most
widespread at present due to the great number of advantages they provide such as: multiplatform, speed of
access or the not requiring extremely powerful hardware among others. The fact that so many web applications
are being developed, makes grotesque the volume of information that it is generated daily. In the management
of all this information, it appears the entity reconciliation problem, which is to identify objects referring to
the same real-world entity. This paper proposes to give a solution to this problem through a web perspective.
To this end, the NDT methodology has been taken as a reference and has been extended adding new activities,
artefacts and documents to cover this problem.Ministerio de Economía y Competitividad TIN2013-46928-C3-3-RMinisterio de Economía y Competitividad TIN2016-76956-C3-2-RMinisterio de Economía y Competitividad TIN2015-71938-RED
A Model-Driven Approach for Business Process Management
The Business Process Management is a common mechanism recommended by a high number of standards for the management of companies and organizations. In software companies this practice is every day more accepted and companies have to assume it, if they want to be competitive. However, the effective definition of these processes and mainly their maintenance and execution are not always easy tasks. This paper presents an approach based on the Model-Driven paradigm for Business Process Management in software companies. This solution offers a suitable mechanism that was implemented successfully in different companies with a tool case named NDTQ-Framework.Ministerio de Educación y Ciencia TIN2010-20057-C03-02Junta de Andalucía TIC-578
Las redacciones de los canales "todo noticias" como laboratorio periodístico: los casos de BBC News 24 y Rainews 24
This article examines the ways in which journalistic procedures have been influenced by the digitalization of television newsrooms, within the comparative framework of two “24 hour” news channels. The study is based on research carried out both in a British public service television, (BBC News 24) and an Italian public television (Rainews 24). There are differences in size, culture, structure and output between the two channels analysed. Both newsrooms have introduced wide structural changes, such as allowing journalists to edit the pieces by themselves and to produce news for television and the Internet. Consideration is given to issues such as organizational structure, multi-skilling and journalists´s working habits developed in this process. And it is also examined the issue as to whether these newsrooms are used as a laboratory for testing new technology and organizational systems
Intra-household Time Allocation: Gender Differences in Caring for Children
Der vorliegende Beitrag untersucht auf Basis von Daten des Sozio-oekonomischen Panels für Deutschland (SOEP), inwieweit selbständige Ausländer in Deutschland überdurchschnittlich hohe Einkommen erzielen. Die Untersuchung zeigt, dass ausländische Selbständige insgesamt höhere Einkommen erzielen als angestellt tätige Ausländer und dass der Unterschied größer ist als bei Selbständigen deutscher Nationalität. Die Konsequenzen dieser Untersuchungsergebnisse für Wirtschaftspolitikund Gründungslehre werden diskutiert. Die Ergebnisse der Untersuchung zeigen differenzierten Forschungsbedarf im Hinblick auf unterschiedliche Optionen der Entrepreneurship Education. This paper analyses the intra-household allocation of time to show gender differences in childcare. In the framework of a general efficiency approach, hours spent on childcare by each parent are regressed against individual and household characteristics, for five samples (Denmark, France, Germany, Italy and Spain), with data being drawn from the European Community Household Panel-ECHP (1994-2001). Empirical results show a clear inequality in childcare between fathers and mothers, with this being more evident in Mediterranean countries. Panel data estimates reveal that, in general, caring tasks are mainly influenced by the presence of young children in the household, by the total non-labor income, and by the ratio of mothers' non-labor income to family's non-labor income, with this latter variable exhibiting a different behavior across genders and across countries.Childcare, gender differences, intra-household allocation, time use
El infoentretenimiento en los informativos líderes de audiencia en la Unión Europea
Este artículo analiza los temas de infoentretenimiento presentes en los informativos de mayor audiencia en la Unión Europea. El infoentretenimiento se establece en aquellas noticias que tratan acerca de la cultura popular (cine, música, videojuegos…), las curiosidades, el interés humano y la vida de los famosos. El estudio ha sido realizado sobre una muestra de los informativos de las televisiones públicas y privadas líderes de audiencia en 2003 y 2004, en trece países de la Unión Europea. En primer lugar, se realiza una revisión bibliográfica y se establece el marco comparativo, de acuerdo con las aportaciones de los principales autores. A continuación, se presenta la metodología empleada en la elaboración del estudio, con la participación de trece investigadores.

Dimensiones y tipología de las actividades de participación de la audiencia en la televisión pública
En el ecosistema mediático, los contenidos televisivos se distribuyen a través de múltiples plataformas (TDT, Internet, móviles…) con renovadas estrategias de participación de los espectadores y usuarios. Las televisiones se adaptan al nuevo entorno, con actividades para que la audiencia pueda compartir, comentar o criticar los programas, al tiempo que se involucra en su diseño, producción o distribución. El análisis de las dimensiones de las actividades de participación de la audiencia en las televisiones públicas, junto con el muestreo de casos, permite elaborar una tipología de esas actividades y vincularlas con la función de servicio público.In the current media ecosystem, television content is distributed through a variety of platforms (TDT, the Web, mobile…) with renewed participation strategies for viewers and users. Public broadcasters are adapting themselves to this new surrounding, and they offer a wide number of activities so that the audience might engage, by sharing, commenting, promoting o criticizing the programs, as well as elaborating their own content or getting involved in their design, production, editing or distribution. The analysis of the multiple dimensions of these participation activities of the audience in the public television channels, together with the recollection of cases, allows to elaborate a typology of such activities and to relate them to the public service function of those broadcasters

Molecular Dynamics Simulations of Lead and Lithium in Liquid Phase
Pb17Li is today a reference breeder material in diverse fusion R&D programs worldwide. Extracting dynamic and structural properties of liquid LiPb mixtures via molecular dynamics simulations, represent a crucial step for multiscale modeling efforts in order to understand the suitability of this compound for future Nuclear Fusion technologies. At present a Li-Pb cross potential is not available in the literature. Here we present our first results on the validation of two semi-empirical potentials for Li and Pb in liquid phase. Our results represent the establishment of a solid base as a previous but crucial step to implement a LiPb cross potential. Structural and thermodynamical analyses confirm that the implemented potentials for Li and Pb are realistic to simulate both elements in the liquid phase
Real Time Control For Airborne Wind Energy Simulators
This thesis develop a real time simulator for an acrobatic kite, called LAKSA Simulink.
The simulator is base on a Matlab code, called LAKSA, which describe the kite behavior
using Lagrangian equation. This code is made of functions with different tasks, from
describing the kite behavior to plot it. This thesis implement Matlab code into Simulink
and add some functionalities: user input, allowing the user to control the kite; and real
time simulation. This thesis aim to create a simulator that work as efficient as possible,
that is why during the development of this thesis, the improvement of the performance
of the simulator and reduction of the computational time have been taken into consideration.
During this thesis, different data regarding the kite behavior and the simulation
performance are obtained and they are analyzed in order to study the effect of the user
input in the kite behavior, and the influence of each task of the simulation in the simulator
