This work presents the preliminary results achieved within a FIRB project aimed to develop innovative support tools for automatic or semi-automatic restoration of damaged digital images concerning archaeological and monumental inheritance of Mediterranean coast. In particular, this paper is focused on a methodology for describing image degradation and its meta-representation for content based storing and retrieval. Our innovative idea is to decompose and store in a conventional RDBMS the images content, considering the damages as objects of the images. Moreover, a set of descriptors(a subset of MPEG7 descriptors) is used for the damage meta representation aimed to content based application. Finally we developed a user-friendly database management tool for manipulating the contents of the database.

In the paper are presented results of very fast transients (VFT) investigations in air-insulated substations (AIS), produced by operations of circuit- breaker and disconnector rated voltage 220 kV. Measurements of these VFT are performed in the AIS at Hydro Power Plant (HPP) Grabovica on River Neretva. Results of computer simulations using EMTP-ATP [1] are presented. In the paper are presented measures for reducing sources of electromagnetic interferences (EMI) emission during switching of air-insulated disconnectors.

In this paper, it is demonstrated that time-frequency techniques may be used for an enhanced diagnosis of the heart disease. Three time-frequency analysis techniques are compared: spectrogram, Wigner distribution and S- method. The results show that the S-method could be used in the heart sounds analysis, and that is also capable of enhancing the diagnostic techniques available to medical personnel.

The analysis of food consumed by a large part of the population is important to establish the nutritional composition of diets to verify if diets are adequate regarding essential nutrients. In the present study, diet analysis results of steel industry workers´ dietary consumption are presented. Workers from 19 to 56 years old were selected and their diets were collected by a duplicate portion technique, including all the meals and beverages consumed over 3 consecutive days. The content of lipids, proteins, carbohydrates, ash, humidity, fiber, vitamins B1 and B2 and piridoxine were determined in 24 diet samples. Comparing the results with the values set by the new dietary recommendation dietary intakes (DRIs), it was observed that the workers´ diets were 100% adequate in carbohydrates and 96% in proteins and lipids. However, dietetic fiber content of the diets was considered inadequate (only 4.2% of adequacy). All the diets were adequate in B1 and B2 vitamins, while 58% of the diets were inadequate in terms of piridoxine.
