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…

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…

Nowadays, the material disassembly is an important issue for the industry. This paper presents an algorithm to sequence the task to be performed in the disassembly of a specific material from a product or to separate all the materials of…

This paper describes a method for the automatic inference of structural transfer rules to be used in a shallow-transfer machine translation (MT) system from small parallel corpora. The structural transfer rules are based on alignment templates, like those used in…

Pararem atenció sobre la construcció “Preposició en + Gerundi” (que té en Marc una de les primeres documentacions en l’expressió de l’anterioritat immediata) i sobre les perífrasis “estar + Gerundi” i “venir a/ en + Infinitiu”. Aquestes qüestions sintàctiques tenen…

The electrochemical reduction of perchloroethylene (PCE) in water has been analyzed through voltammetric studies with a
rotating disc electrode and controlled potential bulk electrolysis. The influence of the mass transport conditions and initial concentration on lead, copper and carbon electrodes…

This special issue of the Journal of Physical Agents is devoted to multi-robot systems. Some might perhaps argue that the term should have been ”multi-agent systems” or ”physical multi-agent systems”, in accordance with the title of the journal. In any…
