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 ...
High capacity FFT-based audio watermarking
Peer-reviewed
Identification of Paintings from Camera-Phone Images
Peer-reviewed
A systematic mapping study of software development with GitHub
GitHub, nowadays the most popular social coding platform, has become the reference for mining Open Source repositories, a growing research trend aiming at learning from previous software projects to improve the development ...
Exploiting feature representations through similarity learning, post-ranking and ranking aggregation for person re-identification
Person re-identification has received special attention by the human analysis community in the last few years. To address the challenges in this field, many researchers have proposed different strategies, which basically ...
Designing a benchmark for the performance evaluation of agent-based simulation applications on HPC
Agent-based modeling and simulation (ABMS) is a class of computational models for simulating the actions and interactions of autonomous agents with the goal of assessing their effects on a system as a whole. Several ...
Combining Monte-Carlo simulation with heuristics for solving the inventory routing problem with stochastic demands
In this paper, we introduce a simulation-based algorithm for solving the single-period Inventory Routing Problem (IRP) with stochastic demands. Our approach, which combines simulation with heuristics, considers different ...
Metodología para el Desarrollo Automatizado de Aplicaciones Seguras Basadas en Agentes Móviles
En este trabajo presentamos una metodología para el diseño de aplicaciones basadas en agentes móviles seguros, y unas herramientas para aplicar esta metodología. Los recientes avances en el campo de la seguridad de los ...
On the k-partition dimension of graphs
As a generalization of the concept of the partition dimension of a graph, this article introduces the notion of the k-partition dimension. Given a nontrivial connected graph G=(V,E), a partition II of V is said to be a ...
From Declarative to Imperative UML/OCL Operation Specifications
An information system maintains a representation of the state of the domain in its Information Base (IB). The state of the IB changes due to the execution of the operations defined in the behavioral schema. There are two ...
Effects of human-machine integration on the construction of identity
Recent developments in social robotics, intelligent prosthetics, brain-computer interfaces, and implants pose new questions as to the effects of technology on identity, society, and the future of humankind. The authors' ...
Analysis of the kind of videos and their utility in physics subjects in virtual and blended environments
Video is becoming one of the main pedagogical tools nowadays. They are very common, mainly in Massive Open Online Courses (MOOC's), but also in virtual universities and more every day in blended and face-to-face learning. ...
Automated and dynamic abstraction of MPI application performance
Developing an efficient parallel application is not an easy task, and achieving a good performance requires a thorough understanding of the program's behavior. Careful performance analysis and optimization are crucial. To ...
A personalized summative model based on learner's effort
Nowadays, instructors apply a large variety of learning methodologies to help learners to achieve the learning outcomes and to assess the knowledge acquired across the course. Formative and summative assessment models are ...
On complexity of post-processing in analyzing GATE-driven X-ray spectrum
In clinical reconstruction of CT images, an effective energy is used instead of total X-ray spectrum. This approximation causes an accuracy decline. To increase the contrast, single source or dual source dual energy CT can ...
A summary of k-degree anonymous methods for privacy-preserving on networks
In recent years there has been a significant raise in the use of graph-formatted data. For instance, social and healthcare networks present relationships among users, revealing interesting and useful information for ...
