BArt: Trading digital contents through digital assets
Since digital artworks are indeed digital content, they face the inherent problem digital content has: the link between content and its original author is very difficult to keep. Additionally, retaining control over digital ...
The MegaM@Rt2 ECSEL project: MegaModelling at Runtime - Scalable model-based framework for continuous development and runtime validation of complex systems
A major challenge for the European electronic industry is to enhance productivity by ensuring quality of development, integration and maintenance while reducing the associated costs. Model-Driven Engineering (MDE) principles ...
Automatic recognition of facial displays of unfelt emotions
Humans modify their facial expressions in order to communicate their internal states and sometimes to mislead observers regarding their true emotional states. Evidence in experimental psychology shows that discriminative ...
Non-verbal communication analysis in victim-offender mediations
We present a non-invasive ambient intelligence framework for the semi-automatic analysis of non-verbal communication applied to the restorative justice field. We propose the use of computer vision and social signal processing ...
Optimal rate allocation in cluster-tree WSNs
In this paper, we propose a solution to the problem of guaranteed time slot allocation in cluster-tree WSNs. Our design uses the so-called Network Utility Maximization (NUM) approach as far as we aim to provide a fair ...

Managing CSCL activity through networking models
This study aims at managing activity carried out in Computer-Supported CollaborativeLearning (CSCL) environments. We apply an approach that gathers and manages the knowledgeunderlying huge data structures, resulting from ...
Simheuristics applications: Dealing with uncertainty in logistics, transportation, and other supply chain areas
Optimization problems arising in real-life transportation and logistics need to consider uncertainty conditions (e.g., stochastic travel times, etc.). Simulation is employed in the analysis of complex systems under such ...
High capacity audio watermarking using the high frequency band of the wavelet domain
This paper proposes a novel high capacity robust audio watermarking algorithm by using the high frequency band of the wavelet decomposition at which the human auditory system (HAS) is not very sensitive to alteration. The ...
Educational data mining and learning analytics: differences, similarities, and time evolution
Technological progress in recent decades has enabled people to learn in different ways. Universities now have more educational models to choose from, i.e., b-learning and e-learning. Despite the increasing opportunities ...
Horizontal collaboration in freight transport: concepts, benefits, and environmental challenges
Since its appearance in the 1990s, horizontal collaboration (HC) practices have revealed themselves as catalyzers for optimizing the distribution of goods in freight transport logistics. After introducing the main concepts ...
Lossless Image Data Embedding in Plain Areas
This letter presents a lossless data hiding scheme for digital images which uses an edge detector to locate plain areas for embedding. The proposed method takes advantage of the well-known gradient adjacent prediction ...
Optimization of aircraft boarding processes considering passengers' grouping characteristics
Aircraft boarding is one of the critical processes affecting the turnaround time when a plane is at an airport. In this work, the aircraft boarding problem is studied with the aim of designing a boarding strategy that ...
Popularization through press advertisements: mobile telephony in Spain (1994-1999)
This paper explores the combined effects of everyday life technological devices and advertisements in constituting an efficient way to scientific popularization. We, therefore, analyze mobile telephony advertisements ...
A Biased-Randomized Algorithm for Redistribution of Perishable Food Inventories in Supermarket Chains
In supermarkets, perishable products need to be sold to consumers before a given deadline, after which their monetary value is significantly diminished or even completely lost. In the case of valuable products that should ...
