Implementation with low cost components of a demo equipment to measure the electromagnetic field emitted by the human body
The low cost equipment described in this article is realised with the well-known LNB – Low Noise Block used for the satellite TV reception. This device has been present for some years in the consumer market. In our arrangement it measures the strength of the electromagnetic field emitted in according to the Planck’s radiation law by one or more persons standing in front of the reception antenna. The equipment is included in a more general exhibit in order to contribute to inform people how the electromagnetic waves are generated.

Three-dimensional TV: is it coming?
In these days we can observe a strong competition among the different entertainment industries – in this paper we deal with video games, cinema, television and home video – and we can sense their effort for excelling, from the technological point of view also, in order to attract more audience. In this framework, the three-dimensional visualization is considered an important tool because it can produce a more immersive view experience and, consequently, a greater satisfaction of the audience. In the different entertainment activities, different 3D display technologies are adopted, and different is the level of their diffusion. In this paper a description of the adopted systems and of the technological trend are reported..

Development of a fuzzy system for the automated annotation of multimedia contents
This article presents a system for the automated characterisation of multimedia contents, based on multimodal data analysis, ontologies and fuzzy logic. The major premise of this framework is that high-level semantic concepts (e.g. the genre of a video or a piece of music) are not defined a priori by static taxonomies, but rather dynamically derived by analysing meaningful aggregations of lower-level features (e.g. colors, peace and rhythm, audio volume, etc.. The use of ontologies allows representing and sharing these concepts and their relationships in a machine understable form. Finally, fuzzy logic expresses the degree of uncertainty in the classification models..
