Vibration-based identification of mechanical properties of orthotropic arbitrarily shaped plates: Numerical and experimental assessment

2018

Abstract An innovative procedure is introduced for the identification of the mechanical parameters of orthotropic plates of arbitrary shape, under various boundary conditions, based on vibration data. The method employs a combination of a convenient Rayleigh-Ritz approach and Particle-Swarm Optimization to estimate elastic constants of the orthotropic material in a straightforward manner, without requiring computationally demanding iterative Finite Element analyses. Specifically, the pb-2 Rayleigh-Ritz procedure is extended and applied to deal with orthotropic plates, simplifying the approach to more easily treat generic plate shapes, taking advantage of the Green's theorem. The method is t…

A New Meta-Heuristic Multi-Objective Approach For Optimal Dispatch of Dispersed and Renewable Generating Units in Power Distribution Systems

2011

The application of stochastic methods in engineering research and optimization has been increasing over the past few decades. Ant Colony Optimization, in particular, has been attracting growing attention as a promising approach both in discrete and continuous domains. The present work proposes a multi-objective Ant Colony Optimization for continuous domains showing good convergence properties and uniform coverage of the non-dominated front. These properties have been proved both with mathematical test functions and with a complex real world problem. Besides the second part of the chapter presents the application of the new algorithm to the problem of optimal dispatch of dispersed power gene…

An evaluation of recent local image descriptors for real-world applications of image matching

2019

This paper discusses and compares the best and most recent local descriptors, evaluating them on increasingly complex image matching tasks, encompassing planar and non-planar scenarios under severe viewpoint changes. This evaluation, aimed at assessing descriptor suitability for real-world applications, leverages the concept of approximated overlap error as a means to naturally extend to non-planar scenes the standard metric used for planar scenes. According to the evaluation results, most descriptors exhibit a gradual performance degradation in the transition from planar to non-planar scenes. The best descriptors are those capable of capturing well not only the local image context, but als…

Evaluating Correlations in IoT Sensors for Smart Buildings

2021

International audience; In this paper we introduce a dataset of environmental information obtained via indoor and outdoor sensors deployed in the SMART Infrastructure Facility of the University of Wollongong (Australia). The acquired dataset is also made open-sourced along with this paper. We also propose a novel approach based on an evolutionary algorithm to determine pairs of correlated sensors. We compare our approach with three other standard techniques on the same dataset: on average, the accuracy of the evolutionary method is about 62,92%. We also evaluate the computational time, assessing the suitability of the proposed pipeline for real-time applications.

Istruttoria tecnico-scientifica nel giudizio a quo e giudizio di legittimità costituzionale: il caso dell’obbligo vaccinale nella decretazione d’urge…

2022

Muovendo dall’ordinanza n. 38 del 2022 del Consiglio di giustizia amministrativa per la Regione siciliana (CGARS), il contributo si sofferma a) sull’estensione per analogia degli obblighi vaccinali; b) su oscurità ed incoerenze della disciplina sugli obblighi vaccinali in tema di accesso alle strutture socio-sanitarie. Il contributo si incentra poi sull'istruttoria tecnico-scientifica e la motivazione sulla non manifesta infondatezza delle questioni di legittimità costituzionale aventi ad oggetto la disciplina sull'obbligo vaccinale e sugli aspetti problematici dell'ordinanza di rimessione del CGARS.

El declive de la ética de las capacidades

2013

Capability approach is one of the most important contributions of contemporary political philosophy to the subject of international distributive justice and more generally to the implementation of development policies. In this paper I aim to shed light on some pitfalls of the last production of Amartya Sen and Martha Nussbaum. Sen’s last book “The idea of justice” introduced his theory as a “comparative” approach to issues of justice, while rejecting “transcendental” approaches such as Rawls’one. I will show how this dichotomy between comparative and transcendental approach is mistaken, since it rests on wrong assumptions on what we can require from a theory of justice. As far as Nussbaum i…

Contatti culturali, identità e popolamento nel territorio imerese

2016

Il lavoro prende in considerazione il problema dei rapporti tra coloni greci e comunità indigene nel territorio di Himera, sulla base dei risultati della prospezione archeologica condotta per tre decenni nelle valli dei fiumi Imera settentrionale, Torto e S. Leonardo. Vengono esaminati gli elementi di cultura materiale che permettono di definire i modi dell'interazione culturale tra coloni e indigeni, nonché di ricostruire i paesaggi politici, socio-economici e il paesaggio del sacro nelle diverse aree indagate e nei diversi comprensori. La ricerca infatti permette di delineare, oltre alle usuali organizzazioni insediative e agricole della chora politiké e della éremos chora, anche articola…

Settore L-ANT/09 - Topografia AnticaSettore L-ANT/07 - Archeologia ClassicaThis work focuses on the problem of cultural contacts between Greek colonists and indigenous communities in the territory of Himera based on the results of the archaeological survey conducted for three decades in the valleys of the northern Imera Torto and S. Leonardo rivers. The elements of material culture that enable us to define the ways of cultural interaction between settlers and indigenous peoples as well as to reconstruct the political socio-economic and sacred landscapes in the various districts investigated are examined. In fact the research allows to outline in addition to the usual settlement and agricultural organizations of chora politiké and éremos chora articulated areas within the territory of Himera and to understand the landmarks of the rural settlement alongside the presence of highland settlements . Therefore the center-periphery approach is abandoned for a more articulated analysis demonstrating different forms of settlement and cultural contact in the three river valleys of the Himera hinterland.

"Memorie dal sottosuolo". Una prospettiva di indagine sul simbolismo rituale delle feste religiose "tradizionali"

2017

In 1945, writing about the procession of Our Lady of Viggiano, Carlo Levi presents us a peasant world characterized by archaic beliefs and ritual practices, another world « where seasons run on peasant fatigue, [...] like three thousand years before Christ », a world « veiled with black veils, fiery and earthly [...] which you do not enter without a key of magic ». If that other world of the peasants seems to have come to an end today, the beliefs, practices and ritual symbols of reputed “pre-Christian” precedence or in any case alien to the official liturgy, as witnessed by Levi and many other narrators and demoanthropologists from the 19th and 20th century are not, however, definitively l…
