Study objectives: (1) To describe the union and life cycle of family rituals, such as specific habits of sharing daily meals, special events or other family activities, and (2) to analyse the relation between the practice of family rituals and…

In the convergence theory of multisplittings for symmetric positive definite (s.p.d.) matrices it is usually assumed that the weighting matrices are scalar matrices, i.e., multiples of the identity. In this paper, this restrictive condition is eliminated. In its place it…

The Workshop of Physical Agents intends to be a forum for information and experience exchange in different areas regarding the concept of agent on physical environments, especially applied to the control and coordination of autonomous systems: robots, mobile robots, industrial…

This paper presents a brief summary of the post-proceedings of the special session on practical applications held in the framework of IWANN 2009. The special session was supported by the THOMAS (TIN2006-14630-C03-03) project and aims at presenting the results obtained…

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,…

The use of numerical values for the chemical components of waters from an aquifer as input data for factor analysis is shown to be sometimes more convenient than the use of the logarithms of these figures. Factor analysis was applied…

We propose a two step method which enables us to obtain transmission Holographic Optical Elements of high diffraction efficiency as well as a good signal-to-noise relation. By means of a device using partially coherent light, a master Holographic Optical Element…

In this paper we present a novel approach to assigning roles to robots in a team of physical heterogeneous robots. Its members compete for these roles and get rewards for them. The rewards are used to determine each agent’s preferences…

We examine the evolution of the refractive index modulation when recording gratings in an acrylamide based photopolymer. A nonlocal diffusion model is used to predict theoretically the grating evolution. The model has been developed to account for both nonlocal spatial…
