THE RELATION BETWEEN EXPERIENCE, EDUCATION AND AI
No full textThe relationship between A.I. and education is one of the basic issues of
contemporary educational research. From this perspective, it is quite evi-
dent that learning, within experience, is one of the most important aspects
to analyze the relationship between A.I. and education. To clarify this con-
cept, we have tried to focus, first, on the relationship between experience
and education, as defined by John Dewey’s book Experience and Educa-
tion of 1938, and to focus on some A.I issues related to education just to
understand the relationship between experience, education and A.I

No full textCombining diffractometric and spectroscopic analysis of artificial stones from Palazzo Brasini (Taranto, southern Italy) to characterize materials and constructive systems
No full textThe aim of this work is to give a compositional characterisation of the artificial stones used in the building up of the Taranto (Apulia region, southern Italy) seaplane station, also better known as Palazzo Brasini (named after the architect who designed it), which represents an example of eclecticism from early 20th century monumental style. Diagnostic analyses applied to architecture, and specifically to “artificial stone” - carried out by combining diffractometric technique with spectroscopic ones, i.e. micro-Raman spectroscopy and micro-X-Ray fluorescence – provided information related to the compositional characterization of the material and its mechanical characteristics. They resulted to be compulsory to decode the specific production processes adopted by artisans other than to provide useful information on the interaction between the artefact and the conservation environment and the identification of degradation processes, thus allowing to plan any further restoring protocol. Besides, diagnostic analyses were necessary to highlight the technological know-how and the circulation of knowledge of artificial stone productions by identifying the lithocement components. The main artificial stone production features regard the use of saffron as a colouring agent in the production of the artificial stones of Palazzo Brasini due to its toxicological safety and stability to light. The use of this pigment is in line with the
autarkic style that characterises the architecture of the 20th century, because it prefers the use of local or at least easily found raw materials. Grossularia, iron oxides, and carbon black were also used as pigment in the adopted artificial stones from Palazzo Brasini and their presence, together with that of saffron, can be likely considered a sort of “trademark” of manufacturing. Chloride ions have been found in the northern facade of the Palazzo Brasini as consequence of it being set in an environment where chloride rich aerosol is remarkable. It was found in samples from the external wall finishing layer from both the lower moulding and the upper moulding. The presence of chlorine in the layer of smooth plaster, suggests a slight penetration of the ion up to the smooth plaster. Besides, the penetration of sulphur into plaster layers (“arriccio” and smooth) – likely associated to the mineralogical phase gypsum as suggested by Raman spectroscopy – is responsible for the transformation reaction of calcite into anhydrite and may be related to the natural acidity of rainwater/aerosols and physical weathering from temperature change and erosion. The
observation of white efflorescence, in between the sublayer A and B of the external wall finishing layer from lower moulding and upper moulding it is likely a consequence of the aggressive environment is which Palazzo Brasini is set. The proximity to the steel plant ILVA, responsible of high SO2 concentration levels in the aerosol, can be the triggering factor of the sulphate attack on the upper and lower moulding
Revitalizing Marginal Areas of Basilicata (Southern Italy) with Saffron: A Strategy Approach Mixing Alternative Cultivation System and Land Suitability Analysis
Get PDFThe abandonment of farmland in Europe is a significant issue due to its environmental, socio-economic, and landscape consequences. This tendency mainly impacts marginal and inner areas, located far from large urban districts, because of biophysical and/or socio-economic factors. Although European and national regulations try to turn the fragility of these territories into an opportunity for sustainable development, many of these areas, especially in southern Europe, continue to suffer socio-economic disparities. For this reason, it is necessary to consider regional and district-wide initiatives that can economically revitalize marginal areas while safeguarding their natural capital. Alternative cropping systems, capable of optimizing the quality of some food crops, can play an essential role in the economic development of populations living in marginal areas. These areas, represented by inland zones often abandoned due to the difficulty of applying mechanized agriculture, can represent an opportunity to rediscover sustainable and profitable practices. Among the high-value crops, saffron (Crocus sativus L.), “red gold” and “king of spices”, stands out for its potential. Indeed, thanks to the use of tuff tubs, a more eco-sustainable choice compared to the plastic pots already mentioned in the literature, it is possible to improve the quality of this spice. Furthermore, Crocus sativus L. not only lends itself to multiple uses but also represents a valid opportunity to supplement agricultural income. This is made possible by its high profitability and beneficial properties for human health, offering a way to diversify agricultural production with positive economic and social impacts. It is known that the saffron market in Italy suffers from competition from developing countries (Iran, Morocco, India) capable of producing saffron at lower costs than European countries, thanks to the lower cost of labor. Therefore, this study seeks to identify marginal areas that can be recovered and valorized through an eco-sustainable cultivation system with the potential to enhance the quality of this spice, making it unique and resilient to competition. Specifically, this paper is organized on a dual scale of investigation: (a) at the local level to demonstrate the economic-ecological feasibility of saffron cultivation through the adoption of an alternative farming technique on an experimental site located in Tricarico (Basilicata—Southern Italy, 40◦37′ N, 16◦09′ E; 472 m. a.s.l.) that, although fertile, is not suitable for mechanized cropping systems; (b) at the regional level through a spatially explicit land suitability analysis to indicate the possible location where to export saffron cultivation. The final map, obtained by combining geo-environmental variables, can be considered a precious tool to support policymakers and farmers to foster a broad agricultural strategy founded on new crop management systems. The adoption of this alternative agroecological system could optimize the use of land resources in the perspective of increasing crop productivity and profitability in marginal agricultural areas
Covariance Matrix Estimation via Geometric Median in Highly Heterogeneous PolSAR Images
Get PDFThe Wishart distribution is a well-established statistical model for characterizing the density of random variables in Polarimetric SAR (PolSAR) data, particularly within homogeneous regions where Gaussian assumptions hold. However, as PolSAR applications expand into heterogeneous environments, alternative statistical models have been developed to better capture the complexity of such areas, playing an important role in tasks such as classification. In this study, we examine the effectiveness of covariance matrix estimation using the median matrix, a technique grounded in optimal transport theory and validated in prior research for its effectiveness. Building on this foundation, we propose the application of a statistical model tailored for heterogeneous regions, i.e., following the G0P distribution, addressing the limitations of traditional assumptions. This method is particularly suitable for high-resolution PolSAR datasets, where the homogeneity hypothesis often does not hold. The experimental results obtained using L-band PolSAR images acquired over Foulum in Denmark demonstrate the robustness of our proposed variant
Managing Livestock Manure
No full textIn this chapter, the importance of livestock manure management and measures to reduce greenhouse gas (GHG) emissions have been discussed in detail. How the proper use of livestock manure can improve farming and how the fertility of the land can be maintained have also been explained. Along with this, various techniques have been mentioned to reduce GHG which can prove helpful in protecting the environment. This chapter describes how with the help of proper management and technical knowledge, we can improve our farming further and protect the environment

Get PDFL’ex Agenzia Coltivazioni Tabacchi di San Giorgio del Sannio come palinsesto architettonico di processi e trasformazioni
No full textSince the 19th Century, the province of Benevento has played a pivotal role in tobacco production and processing in Italy. The Agenzia Coltivazioni Tabacchi (ACT) in San Giorgio del Sannio represents as a significant example of industrial heritage identity, characterised by a continuous evolution of production processes and architectural rewriting. With the introduction of new European agricultural policies at the end of the millennium, following the liberalization of tobacco processing and marketing, a gradual process of production downsizing of the facility was initiated, culminating in its closure in 2001.
This study examines the ACT through its historical, architectural, and structural evo- lution in relation to the region’s economic development. The research methodology integrates extensive archival investigation with a critical typological and structural analysis of the complex, verifying the need for an integrated recovery and outlin- ing possible scenarios of sustainable reconversion between cultural valorization and economic development
Generalized Sasaki Mapping in d0-algebras
No full textWe define the notion of generalized Sasaki mapping on a d0-
algebra. We also introduce d0-algebras with the Sasaki property and, for
such d0-algebras, we construct the generalized Sasaki projection, which turns
out to be a generalized Sasaki mapping
