In this work we propose to use fuzzy prototypes for classification tasks. We create the prototypes by first clusterizing, separately, the available data for each class. Then we create a fuzzy set around each class center, according to clusterization indices that take into account both local and global data. We also investigate the use of an index to guide the process of obtaining a suitable num...

The aim of this bibliography is to provide an introduction to papers and technical reports in the field of delay differential equations and related differential equations. In addition to the title, authors and reference of an article, we provide the abstract which, if the article has previously appeared as a technical report, comes from the published paper unless indicated by a ‡. The main inte...

The literal performance of the symbols contained in a traditional score is not enough to produce expressive music. Human interpreters use musical knowledge that is not explicitly represented in it. This paper presents a knowledge-based approach to introduce expressiveness to the performance of a score by calculating dynamics and tempo envelopes of the piece, combining implicit musical knowledge...

In this paper we give an overview on the application of aggregation operators in data privacy. Applications include data protection methods, as microaggregation, as well as measures to evaluate in what extent data is perturbated information loss measures and satisfy privacy requirements disclosure risk measures.

In March 2009, the fourth NorMAS (Normative Multi-agent Systems) was held at Schloss Dagstuhl Leibniz Center for Informatics. During the seminar, around 30 invited participants presented their current research, and discussed ongoing work and open problems discussed. This special issue presents a few of the papers discussing formals models (both logic and computational implementations) and norma...

We introduce the new concept of community browsing: a group of people browsing the web together and simultaneously. Community browsing is part of the broader notion of shared experience, where individuals share the experience of an event. We have developed a prototype of a mobile application that enables community browsing, and involves new technologies such as a peer-to-peer Electronic Institu...

Package delivery companies compete with each other and have costumers spread over wide areas. We propose a negotiation algorithm that allows companies and individual postmen to negotiate over who delivers what package. This way, package delivery can be made more efficient, yielding a higher profit and/or lower costs for all parties. Our system does not force competing companies to co-operate, b...

We present a computational framework for chord invention based on a cognitive-theoretic perspective on conceptual blending. The framework builds on algebraic specifications, and solves two musicological problems. It automatically finds transitions between chord progressions of different keys or idioms, and it substitutes chords in a chord progression by other chords of a similar function, as a ...
