The use of two relations in L-fuzzy contexts

In the analysis of relations among the elements of two sets it is usual to obtain different values depending on the point of view from which these relations are measured. The main goal of the paper is the modelization of these situations by means of a generalization of the L-fuzzy concept analysis called L-fuzzy bicontext. We study the L-fuzzy concepts of these L-fuzzy bicontexts obtaining some interesting results. Specifically, we will be able to classify the biconcepts of the L-fuzzy bicontext. Finally, a practical case is developed using this new tool.

Replicación Activa en NodeJS con 0MQ

Mi trabajo final de grado se centra en el aprendizaje, desarrollo y divulgación del entorno de programación NodeJS, un entorno orientado a eventos que está basado en el lenguaje de programación JavaScript en el lado del servidor. El enfoque de NodeJS es el desarrollo de aplicaciones de red altamente escalables. La escalabilidad se proporciona por la eficiencia obtenida a lo largo de los años en la optimización de código en los motores de JavaScript por la delegación asíncrona a tareas propias del sistema operativo. Aprovechando estas cualidades, desarrollo la implementación de un algoritmo basado en el modelo de replicación activa consistente en mantener copias de objetos de datos en distintos almacenes de datos. Con este modelo se constituye un sistema distribuido tolerante a fallos y de alta disponibilidad. Para los protocolos de comunicación se utilizan de los socket 0MQ y se desarrollan algunos ejemplos del uso de cada tipo de ellos.

Non-anonymous ballot aggregation: an axiomatic generalization of Approval Voting

We study axiomatically situations in which the society agrees to treat voters with different characteristics distinctly. In this setting, we propose a set of intuitive axioms and show that they jointly characterize a new class of voting procedures, called Type-weighted Approval Voting. According to this family, each voter has a strictly positive and finite weight (the weight is necessarily the same for all voters with the same characteristics) and the alternative with the highest number of weighted votes is elected. The implemented voting procedure reduces to Approval Voting in case all voters are identical or the procedure assigns the same weight to all types. Using this idea, we also obtain a new characterization of Approval Voting.
