This article presents a case study in which the THOMAS architecture is applied in order to obtain a multi-agent system (MAS) that can provide recommendations and guidance in a shopping mall. THOMAS is made up of a group of related…

Mobile agent technology has traditionally been recognized as a very useful approach to build applications for mobile computing and wireless environments. However, only a few studies report practical experiences with mobile agents in a mobile medium. This leads us to…

This paper introduces the development of an infrastructure to study highly complex systems of Ambient Intelligence (AmI) which involve a large number of users. The key ideas about the development of a multi-agent based simulation (MABS) for such purposes, Ubik,…

In this paper we will propose the use of social robots as interface between users and services in a Smart Environment. We will focus on the need for a robot to recognize the user’s feedback, in order to respond and…

A major challenge in deploying robots into the real world is the design of an architectural framework which can provide extended, natural and effective interactions with people. Within this framework, key issues that need to be solved relate to the…

Previously we described a large collection of cloned human DNAs that encode chemically defined missense mutations
within the ribosomal protein S14 sequence. We determined that biologically inactive (i.e. null) alleles resulted primarily
from point mutations targeted to two internal segments…

NFAT (nuclear factors of activated T cells) proteins constitute a family of transcription factors involved in mediating signal transduction. The presence of NFAT isoforms has been described in all cell types of the immune system, with the exception of neutrophils.…

Objective: To explore the opinions of stakeholders on the potential of taxes or subsidies, as measures for tackling obesity in Europe. Design: Structured interviews using Multi-criteria Mapping, a computer based decision support tool. Subjects/Setting: 189 interviewees, drawn from 21 different…

The eye is not a centered system. The line of sight connects the fovea with the center of the pupil and is usually tilted in the temporal direction. Thus, off-axis optical aberrations, mainly coma and oblique astigmatism, are introduced at…

This paper explores additivity-like properties ful…led by bankruptcy rules. Our
main result is that the unique rule satisfying an adittivity-like property is the Minimal Overlap proposed by O'Neill. We also propose some conections relative to
additivity properties in close frameworks…
