During the COVID-19 pandemic, online learning has become an important and widely used form of education. Many studies have pointed out that interaction is key to learning. The Interaction Hierarchy Theory categorizes interactions in remote teaching into three types: operational, informational, conceptual. Operational serves as foundation for all types refers interface learners engage at behavio...

In December 2010, two years after the first Perceptual Learning (PL) conference was held in Beijing, the 2nd meeting was held in Eilat, Israel. It was attended by a large group of researchers of Perceptual Learning who collectively, study its behavioral, computational and physiological characteristics. Sessions were largely informal and left time for discussions. The meeting was followed by thi...

In this paper we face the problem of the automatic selection of relevant levels in a hierarchy of fuzzy segmentations. Today there is a wide variety of techniques (multiscale or hierarchical) to analyze an image with several levels of detail, but they don’t consider that not all the segmentations resulting from this process are interesting for the user. Here we propose a technique based in meas...

We propose an integrated location management and location-aided routing system which organizes the Mobile Ad-hoc Network (MANET) into a two-level hierarchy with the help of Voronoi diagrams. The location information of mobile nodes in a Voronoi zone is summarized using Bloom Filters and distributed among the location servers in the zones. The integrated system has the property that the destinat...
