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 ...
Backwards reasoning for model transformations: method and applications
Model transformations are key elements of model driven engineering. Current challenges for transformation languages include improving usability (i.e., succinct means to express the transformation intent) and devising ...
Addressing mobility in RPL with position assisted metrics
Mobility is still an open challenge in wireless sensor networks (WSNs). Energy efficient routing strategies designed for static WSNs, such as routing protocol for low-power and lossy networks (RPL), generally have a slow ...
Consolidation centers in city logistics: A cooperative approach based on the location routing problem
In the context of city logistics, freight transportation is one of the prominent causes of traffic congestion, high levels of pollution, and safety concerns. To decrease the negative impact of these issues, different methods ...
Spectral Efficient and Energy Aware Clustering in Cellular Networks
The current and envisaged increase of cellular traffic poses new challenges to mobile network operators (MNO), who must densify their radio access networks (RAN) while maintaining low capital expenditure and operational ...
