Experiencia de gamificación en secundaria en el aprendizaje de sistemas digitales
El uso del juego, utilizado siempre en edades tempranas para motivar el aprendizaje, ha sido frecuentemente estigmatizado en edades más avanzadas al considerarse una pérdida de tiempo. Sin embargo, en los últimos años el ...
On the use of learnheuristics in vehicle routing optimization problems with dynamic inputs
Freight transportation is becoming an increasingly critical activity for enterprises in a global world. Moreover, the distribution activities have a non-negligible impact on the environment, as well as on the citizens' ...
Dynamic pricing for vehicle ferries: using packing and simulation to optimize revenues
We propose an improved heuristic approach to the vehicle ferry revenue management problem, where the aim is to maximize the revenue obtained from the sale of vehicle tickets by varying the prices charged to different vehicle ...
Preferred spatial frequencies for human face processing are associated with optimal class discrimination in the machine
Psychophysical studies suggest that humans preferentially use a narrow band of low spatial frequencies for face recognition. Here we asked whether artificial face recognition systems have an improved recognition performance ...
Enhanced multi-directional local search for the bi-objective heterogeneous vehicle routing problem with multiple driving ranges
The transportation sector accounts for a significant amount of greenhouse gas emissions. To mitigate this problem, electric vehicles have been widely recommended as green vehicles with lower emissions. However, the driving ...
Subjectively adapted high capacity lossless image data hiding based on prediction errors
This article reports on a lossless data hiding scheme for digital images where the data hiding capacity is either determined by minimum acceptable subjective quality or by the demanded capacity. In the proposed method data ...

Off-Line Evaluation of Mobile-Centric Indoor Positioning Systems: The Experiences from the 2017 IPIN Competition
The development of indoor positioning solutions using smartphones is a growing activity with an enormous potential for everyday life and professional applications. The research activities on this topic concentrate on the ...
Lightweight and static verification of UML executable models
Executable models play a key role in many software development methods by facilitating the (semi)automatic implementation/execution of the software system under development. This is possible because executable models promote ...
Using simulation to estimate critical paths and survival functions in aircraft turnaround processes
In the context of aircraft turnaround processes, this paper illustrates how simulation can be used not only to analyze critical activities and paths, but also to generate the associated survival functions ' thus providing ...
Diffusive and arrestedlike dynamics in currency exchange markets
This work studies the symmetry between colloidal dynamics and the dynamics of the Euro-U.S. dollar currency exchange market (EURUSD). We consider the EURUSD price in the time range between 2001 and 2015, where we find ...
Unsupervised steganalysis based on artificial training sets
In this paper, an unsupervised steganalysis method that combines artificial training sets and supervised classification is proposed. We provide a formal framework for unsupervised classification of stego and cover images ...
Fruitful student interactions and perceived learning improvement in DSLab: A dynamic assessment tool for distributed programming
This work presents an automated assessment tool for online distributed programming, called DSLab. It is a web-based environment that provides a transparent deployment and execution of assignments in remote computers, a ...
Deborah Lupton, Digital sociology
In Digital Sociology, Deborah Lupton discusses how digital technologies have been incorporated into social contexts, institutions, and notions of selfhood and embodiment. The author argues that we now live in a digital ...

Electric vehicles in logistics and transportation: A survey on emerging environmental, strategic, and operational challenges
Current logistics and transportation (L&T) systems include heterogeneous fleets consisting of common internal combustion engine vehicles as well as other types of vehicles using 'green' technologies, e.g., plug-in hybrid ...
Deliberative platform design: The case study of the online discussions in Decidim Barcelona
With the irruption of ICTs and the crisis of political representation, many online platforms have been developed with the aim of improving participatory democratic processes. However, regarding platforms for online ...
Embedding emotion awareness into e-learning environments
In this work we investigate the importance of emotion awareness in e-learning environments, with emphasis to Computer Supported Collaborative Learning (CSCL) activities. Our presented solution involves a new conceptual ...
