Improvement of JXTA Protocols for Supporting Reliable Distributed Applications in P2P Systems
In any distributed application, the communication between the distributed processes/nodes of the distributed systems is essential for both reliability and efficiency matters. In this work we address this issue for distributed ...
Experiences in digital circuit design courses: a self-study platform for learning support
The synthesis of digital circuits is a basic skill in all the bachelor programmes around the ICT area of knowledge, such as Computer Science, Telecommunication Engineering or Electrical Engineering. An important hindrance ...
Geomfinder: a multi-feature identifier of similar three-dimensional protein patterns: a ligand-independent approach
Since the structure of proteins is more conserved than the sequence, the identification of conserved three-dimensional (3D) patterns among a set of proteins, can be important for protein function prediction, protein ...
Deriving Operation Contracts from UML Class Diagrams
Class diagrams must be complemented with a set of system operations that describes how users can modify and evolve the system state. To be useful, such a set must be complete (i.e. through these operations, users should ...
Individual differential privacy: A utility-preserving formulation of differential privacy guarantees
Differential privacy is a popular privacy model within the research community because of the strong privacy guarantee it offers, namely that the presence or absence of any individual in a data set does not significantly ...
Standardized low-power wireless communication technologies for distributed sensing applications
Recent standardization efforts on low-power wireless communication technologies, including time-slotted channel hopping (TSCH) and DASH7 Alliance Mode (D7AM), are starting to change industrial sensing applications, enabling ...
A Survey on Detection Techniques to Prevent Cross-Site Scripting Attacks on Current Web Applications
Security is becoming one of the major concerns for web applications and other Internet based services, which are becoming pervasive in all kinds of business models, organizations, and so on. Moreover, critical systems such ...
A Service-oriented Platform for the Enhancement and Effectiveness of the Collaborative Learning Process in Distributed Environments
Modern on-line collaborative learning environments are to enable and scale the involvement of an increasing large number of single/group participants who can geographically be distributed, and who need to transparently ...
A Secure and Anonymous Cooperative Sensing Protocol for Cognitive Radio Networks
Spectrum is an essential resource for the provision of mobile services. In order to control and delimit its use, governmental agencies set up regulatory policies. Unfortunately, such policies have led to a deficiency of ...
Review of Robust Cooperative Spectrum Sensing Techniques for Cognitive Radio Networks
Cognitive radio networks sense spectrum occupancy and manage themselves to operate in unused bands without disturbing licensed users. The detection capability of a radio system can be enhanced if the sensing process is ...
Accuracy and bias in Spanish secondary school students' self-concept of math ability: the influence of gender and parental educational level
The present two-wave longitudinal study investigated the accuracy or bias in students¿ math self-concept of ability during the transition to high school from the last year of secondary compulsory education (10th grade). ...
Social flow in social MOOCs
Flow theory is a way to explain how humans can be self-motivated and reach a state of high focus and intense, very effective learning. Usually this theory is merely descriptive but recently it has also been operationalized ...
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 ...
La adquisición de las competencias profesionales a través de las prácticas curriculares de la formación inicial de maestros
Las prácticas profesionales constituyen un elemento esencial en los planes de formación inicial de maestros, contribuyendo no sólo al desarrollo de competencias, sino también a su orientación profesional y posterior inserción ...

Beyond WhatsApp: Older people and smartphones
This paper analyzes how older people, living in Spain, use smartphones and smartphone applications.Using a mixed methods approach, we compare quantitative results obtained by tracking mobile app usageamongst different ...
Unravelling local adaptive capacity to climate change in the Bolivian Amazon: the interlinkages between assets, conservation and markets
This paper examines household adaptive capacity to deal with climatic change among the Tsimane', an indigenous society of the Bolivian Amazon, and explores how exposure to conservation policies and access to markets shape ...
A multi-start simheuristic for the stochastic two-dimensional vehicle routing problem
The two-dimensional vehicle routing problem (2L-VRP) is a realistic extension of the classical vehicle routing problem where customers' demands are composed by sets of non-stackable items. Examples of such problems can be ...
J3Gen: A PRNG for low-cost passive RFID
Pseudorandom number generation (PRNG) is the main security tool in low-cost passive radio-frequency identification (RFID) technologies, such as EPC Gen2. We present a lightweight PRNG design for low-cost passive RFID tags, ...
