To analyze the present status of rheumatological research in Spain, three indicators have been evaluated: use of the difference study designs, use of statistical techniques and relevance of the studies. This last point was determined by the comparison of the…

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

The aim of this study is to develop a color visualization system for multispectral images in the near-infrared region (NIR, 800–1000 nm). Samples with the same color or appearance in the visible region, which are therefore indistinguishable to the human

The purpose of this paper is to present a specific testing protocol for monitoring upper-body strength using medicine ball throws. The protocol is composed of three tests: throw without countermovement, throw with countermovement, and throw with countermovement of a medicine…

The growth of China’s outbound tourism is a source of both threats and opportunities for European countries. Therefore, European tourism institutions and companies should focus their attention on this emerging market. The objective of this paper is to analyze the…

Electrocrystallisation of lead dioxide on glassy carbon electrodes was studied in 1 M HNO3+ 0.1 M Pb(NO3)2 in the presence of ultrasound using chronoamperometry and scanning electron microscopy. In order to compare these results with those obtained in the absence…

An approximation scheme to obtain the period for large amplitude oscillations of a simple pendulum is analysed and discussed. The analytical approximate formula for the period is the same as that suggested by Hite (2005 Phys. Teach. 43 290), but…

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,…

There is considerable interest in real-world formation-maintenance tasks, where robots move together while maintaining a geometric shape. This interest is motivated by promise of robustly and efficiently moving multiple robots along a path, guided by a human operator. This paper…

In this review, a comparison between the Lewis acid catalysed and organocatalysed 1,3-dipolar cycloaddition is presented with special focus on the enantioselective synthesis of five-membered hetero- or carbocyclic systems, is described. These reactions exhibit very interesting features, but the most…
