Abstract— Peer-to-Peer ( P2P ) systems have been the center of attention in recent years due to their advantage . Since each node in such networks can act both as a service provider and as a client , they are subject to different attacks . Therefore it is vital to manage confidence for these vulnerable environments in order to eliminate unsafe peers . This paper investigates the use of genetic ...

This paper presents an algorithm for induction of ensembles of decision trees, also referred to as decision forests. In order to achieve high expressiveness the trees induced are multivariate, with various, possibly user-defined tests in their internal nodes. Strongly typed genetic programming is utilized to evolve structure of the tests. Special attention is given to the problem of diversity o...

Physical or simulated agents sharing an environment with humans must evaluate the impact of their own and other agents’ actions in the specific social and cultural context. It is desirable that this social calculus aligns itself with the models developed in sociology and psychology however, it needs to be expressed in an operational, algorithmic form, suitable for implementation. While we can d...

The T-calculus is a typed functional extension of the tiled signal algebra previously defined for handling, with advanced synchronization feature, audio or musical finite signals. Primarily designed for programing interactive music systems, the T-calculus can also be seen as a multi-purpose programing language proposal that addresses the difficult problem of globally asynchronous and locally sy...

Langerhans cells (LCs), residing in the epidermis, are able to induce potent immunogenic responses and also mediate immune tolerance. We propose that tolerogenic of LCs directed by signaling from epidermis involve counter-acting gene circuits coupled a core maturation module. base our analysis on recent genetic genomic findings facilitating understanding molecular mechanisms controlling these d...
