Stavo per scivolare, ho pensato a Wittgenstein!. Etnopragmatica di un concetto

2016

In questo saggio, esploro la porta semiotica e pragmatica di un’azione (‘scivolare’), comunemente appartenente all’ambito del quotidiano, per mostrarne invece la valenza teorica e metateorica oltre che d’ordine pratico. Le domande che mi pongo sono le seguenti: come si può riflettere sul quotidiano in chiave antropologica? Come analizzare il senso di un concetto soltanto in apparenza d’uso comune? Come eludere la metafisica radicata nelle nostre proprie analisi? Per rispondere a queste domande, mi sono avvalso del concetto di gioco linguistico formulato da Wittgenstein rinviando allo ‘scivolare’ in opposizione all’‘attrito’ e, infine, al concetto stesso di ‘gioco linguistico’. Ho dunque mes…

FLUMO: FLexible Underwater MOdem

2019

The last years have seen a growing interest in underwater acoustic communications because of its applications in marine research, oceanography, marine commercial operations, the offshore oil industry and defense. High-speed communication in the underwater acoustic channel has been challenging because of limited bandwidth, extended multipath, refractive properties of the medium, severe fading, rapid time variation and large Doppler shifts. In this paper, we show an implementation of a flexible Software-Defined Acoustic (SDA) underwater modem, where modulation parameters are completely tunable to optimize performance. In particular, we develop the system architecture following two key ideas. …

EXTRACURRICULAR ACTIVITIES AND THEIR INFLUENCE ON UNIVERSITY'S ATTRACTIVENESS

2015

This paper aims to determine the respondents' opinion regarding the extracurricular activities within their universities and to establish the influencing factors on the university's attractiveness. This study has been elaborated based on the quantitative research, through primary research and the data is gathered through the questionnaire method. The research has been developed within the "Lucian Blaga" University of Sibiu, Politehnica University Timișoara, Babeș Bolyai University Cluj, Bucharest University of Economic Studies and Politehnica University Bucharest and 728 students have been questioned in the period June - September 2014. As a result of the analysis, an influence of the extra…

Voltage source inverters: An easy approach for fast fault detection

2013

Fault-tolerant converters have been widely investigated for years and nowadays an extensive technical literature on this field exists. This paper presents a novel fault detection algorithm based on a simple geometrical approach. In the algorithm analysis both the case of faults in single device and the loss of an entire inverter leg have been considered. The proposed methodology is characterized by simplicity, low computational and implementation effort with a consequent fast execution and easy control integration. The suggested algorithm is verified by means of experimental tests and reveals a valid and suitable alternative to the existing state of the art in the field of inverter fault de…

Reliability Analysis of Three Homogeneous Fault-tolerant Inverter Topologies

2016

Abstract—In this article, non-redundant fault-tolerant inverter topologies are addressed. A novel fault-tolerant control strategy which enhances performances during post-fault operation is proposed. Benefits from the proposed strategy over conventional fault-tolerant topologies are investigated in terms of system reliability. Cost, post-fault performances, and system reliability of the proposed solution are compared with both a conventional triac-based fault-tolerant inverter and a T-type inverter. The reliability analysis of each selected configuration is carried out by means of Markov chains. The analysis is validated through a comparison of reliability and sensitivity curves. As shown by…

Gioacchino Ventura: la Sicilia nell’Italia confederale

2023

Gioacchino Ventura è stato un filosofo e religioso teatino dalla vita intensa e a tratti perfino avventurosa, conosciuto prevalentemente per la sua partecipazione ai moti indipendentistici siciliani del Quarantotto, auspicando una soluzione di tipo confederale per l’unità d’Italia.

Due democratiche cristiane alla Consulta nazionale: Laura Bianchini e Angela Maria Guidi Cingolani

2022

Questo articolo appartiene a uno studio più ampio che mira a ricostruire una tradizione politica femminile per comprendere alcune delle ragioni persistenti dietro il divario di genere tra accesso formale e sostanziale alle decisioni. L’obiettivo finale è quello di evidenziare il ruolo e il contributo delle donne, soprattutto di quelle che sono finite nell’oblio, nella costituzione di un’Italia democratica e repubblicana fin dalle loro prime partecipazioni all’Assemblea Nazionale Consultiva. L’Archivio della Camera dei Deputati, l’Archivio dell’Istituto Sturzo e gli articoli delle riviste dell’epoca sono state le fonti primarie della ricerca.Il 25 settembre 1945 si inaugura la Consulta che r…

Design and Assessment of Optimized EMI Filters for Avionic Applications

2018

This paper presents a procedure to design EMI filters to reduce the electromagnetic disturbances generated by electrical apparatus used in avionic environment. The method proposed can be useful to save weight and size of the attenuation systems, and keep their effectiveness in agreement with the standard requirements. A design of a set of different filters with different topological characteristics is presented for a case study about an electrical actuator used for an aircraft onboard application. Performances and reliabilities of the attenuation systems are assessed by suitable full compliance experimental tests.
