diasis

 


Diasis operates in the field of identification for the protection and safeguard of artworks and of non-invasive diagnostic of cultural goods. The initiative is based on the experience matured from the adaptation of applied techniques in the geophysics field, as answer to the existing problems created by the protection of artistic and cultural heritage.

 

Services

The services offered by Diasis could be grouped in two main activities: the identification of artworks and the non-invasive diagnosis of cultural goods. The innovative techniques of analysis lead to two patents: the sonic imprint and the GTT Dromocrona Tomografica Globale. Both techniques are non-invasive and possibly applicable in situ, thanks to the portability of the instruments.

 

Sonic imprint

The sonic imprint is a unique identification that detects a characteristic unequivocally bonded to every physical piece able to vibrate and that remains constant over time. Two apparently equal pieces, for instance, two objects produced industrially in series, differ at least on internal defects that alter the sonic imprint in a more or less evident way. The spectre that characterises the sonic imprint is graphically represented as a bar code that unequivocally identifies the object.

 

Non-invasive diagnostic

The intervention comprehends:

-       The study and analysis of the goods according to their physical characterisation, even finalised to the archiving in technical files;

-       The study and analysis of the conditions of degradation of the pieces, even as technical support to the projects and to the restoration interventions;

-       Monitoring of the physical and chimico-physical conditions of the pieces, through the variation of particular parameters related to the environmental conditions.

Among the techniques used in diagnostic, GTT is particularly relevant. It is a methodology that uses ultrasonic waves in order to evaluate the degraded superficial layer of statues and ornaments in stone. The sonic imprint is also applied by Diasis in diagnostic, as it allows to identify eventual internal degradations of the pieces without undermining it, unlike the other techniques as coring.

 

Relations with institutions

Diasis is a spin-off of Università degli Studi di Palermo. The group is actually considering its relations with the Ministero dei Beni Culturali and the Nucleo Tutela Patrimonio Artistico dell’Arma dei Carabinieri in order to include the sonic imprint as a cataloguing system of the cultural goods.

The creation of a “certified” data bank of sonic imprint could be a valid help to the fight against theft and counterfeiting of artworks. It could also be helpful for the procedural fulfillments envisaged by the norms for the international traffic of cultural goods.
