Artificial Neural Networks (ANNs) are grouped within connectionist techniques of Artificial Intelligence. In particular, Recurrent Neural Networks are a type of ANN which is widely used in signal reproduction tasks and sequence analysis, where causal relationships in time and space…

The paper presents a coordinated process through which the situated agents are capable of working jointly using knowledge about their skills to interact with other similar entities. A good coordination is reached because each situated agent is able to represent…

Aneurysms of the sinus of Valsalva (SV) and the atrial septum are a rare association. We report the case of a 28-year-old woman, who was admitted to our department complaining of progressive dyspnea of 10 days of evolution, five hours…

When people think spatially, they do not usually consider geographic coordinates nor projections. Facing questions having a spatial sense, people do not answer with maps or coordinates, but use some references whose spatial location is "well known". For instance, the…
