A framework to identify primitives that represent usability within Model-Driven Development methods
2014
Context: Nowadays, there are sound methods and tools which implement the Model-Driven Development approach (MDD) satisfactorily. However, MDD approaches focus on representing and generating code that represents functionality, behaviour and persistence, putting the interaction, and more specifically the usability, in a second place. If we aim to include usability features in a system developed with a MDD tool, we need to extend manually the generated code. Objective: This paper tackles how to include functional usability features (usability recommendations strongly related to system functionality) in MDD through conceptual primitives. Method: The approach consists of studying usability guide…
Dades massives i estadística: La perspectiva d'un estadístic
2014
Les dades massives (big data) representen un recurs sense precedents per a afrontar reptes científics, econòmics i socials, però també incrementen la possibilitat de traure conclusions enganyoses. Per exemple, l’ús d’enfocaments basats exclusivament en dades i que es despreocupen de comprendre el fenomen en estudi, que s’orienten a un objectiu esmunyedís i canviant, que no tenen en compte problemes determinants en la recopilació de dades, que resumeixen o «cuinen» inadequadament les dades i que confonen el soroll amb el senyal. Repassarem alguns casos reeixits i il·lustrarem com poden ajudar els principis de l’estadística a obtenir una informació més fiable de les dades. També abordarem els…
The Information and Communication Technologies in the school sys-tem. A review of the research lines
2005
This paper offers a classification of research trends and perspectives about processes oriented to incorporate information and communication technologies (ICT) in schools. Identified are four research trends: a) studies about indicators of computers quantity in school systems; b) studies about computer effects in learning; c) studies about opinion, perspectives and attitudes of educational agents to ICT; and d) studies about computers' educational use in classroom and colleges. This paper finishes with a synthesis of current knowledge about projects and programs intended for the embodiment of ICT in school systems.

Modeling, evaluation, and scale on artificial pedestrians: a literature review
2017
Modeling pedestrian dynamics and their implementation in a computer are challenging and important issues in the knowledge areas of transportation and computer simulation. The aim of this article is to provide a bibliographic outlook so that the reader may have quick access to the most relevant works related to this problem. We have used three main axes to organize the article's contents: pedestrian models, validation techniques, and multiscale approaches. The backbone of this work is the classification of existing pedestrian models; we have organized the works in the literature under five categories, according to the techniques used for implementing the operational level in each pedestrian …
Pathway network inference from gene expression data
2014
[EN] Background: The development of high-throughput omics technologies enabled genome-wide measurements of the activity of cellular elements and provides the analytical resources for the progress of the Systems Biology discipline. Analysis and interpretation of gene expression data has evolved from the gene to the pathway and interaction level, i.e. from the detection of differentially expressed genes, to the establishment of gene interaction networks and the identification of enriched functional categories. Still, the understanding of biological systems requires a further level of analysis that addresses the characterization of the interaction between functional modules. Results: We presen…
COEDU-IN Project: an inclusive co-educational project for teaching computational thinking and digital skills at early ages
2021
Learning to program is the new literacy of the 21st century. Computational thinking, closely related to programming, requires thinking and solving problems with different levels of abstraction and is independent of hardware devices. The early childhood education stage provides teachers with the opportunity to lay the foundations for a comprehensive quality education using innovative tools and technologies. Educational robotics in early childhood education becomes a tool that facilitates the acquisition of knowledge to children, playfully, based on the principles of interactivity, social interrelationships, collaborative work, creativity, constructivist and constructionist learning, and a st…

CONTROVERSIAS EN TORNO AL SOFTWARE LIBRE: PRÁCTICAS Y DISCURSOS EN LA DOCENCIA UNIVERSITARIA VALENCIANA
2008
Resumen basado en el de la publicación La progresiva implantación del software libre en los ámbitos universitarios, se acompaña de un discurso construido sobre las controversias que rodean a esta tecnología. Para el análisis de este problema se utiliza el modelo de 'espacios controversiales' propuesto por Nudler, definiendo uno de estos espacios en torno a la aplicación de las tecnologías informáticas en las enseñanzas universitarias. El supuesto es que el debate sobre el copyleft está alcanzando también al discurso pedagógico que acompaña a las aplicaciones de estas tecnologías. Este modelo es el que se trata de aplicar al estudio de cómo se formulan tales controversias en la difusión del …
Engineering multi-agent systems: State of affairs and the road ahead
2019
International audience; The continuous integration of software-intensive systems together with the ever-increasing computing power offer a breeding ground for intelligent agents and multi-agent systems (MAS) more than ever before. Over the past two decades, a wide variety of languages, models, techniques and methodologies have been proposed to engineer agents and MAS. Despite this substantial body of knowledge and expertise, the systematic engineering of large-scale and open MAS still poses many challenges. Researchers and engineers still face fundamental questions regarding theories, architectures, languages, processes, and platforms for designing, implementing, running, maintaining, and e…
