Il patrimonio dei prodotti locali ed i “mercati del contadino”. Generazione di valori sociali e di relazione nei territori

Il presente contributo si propone di analizzare le specificità che caratterizzano il processo di sviluppo dei mercati contadini in una città metropolitana come Catania, attraverso un caso studio. A tal fine, sono state condotte interviste volte sia a raccogliere testimonianze dirette, sia ad approfondire gli aspetti applicativi e l’impatto delle pratiche sociali, considerando al contempo le peculiarità e le criticità emergenti. I risultati evidenziano le dinamiche di reinven- zione del rappor...

Remarks on the formulation of model order estimation

The model order determination for linear time-invariant systems from measured input-output signals is essential for defining the right structure of a real process. The purpose of this paper is to note some concepts regarding the order determination, approaching the problem from an empirical point of view. At first the generalization to an uncertain measurement set of a simple criterion for order estimation is proposed. Then some ideas, that lead to the model order determination, are reviewed ...

About low frequency digital filter realization by means of a microcomputer

In the dynamic studies, in order to realize high speed data handling systems and to perform very accurate measurements, low frequency signal filtering has been improved by using digital techniques. In this paper there are briefly analyzed two band pass filtering systems realized by microcomputer, a FIR and an IIR type: both are referred to one general microcomputer architecture. From a time analysis of implemented algorithms it is pointed out the compatibility between acquisition and filterin...
