"Venne in grandissimo nome, e ritenuto primo in Italia per lavori di oreficeria"
No full textDefinito il "Cellini moderno", Farnesi emerge in effetti come un protagonista dell'arte e della tecnica orafa di secondo Ottocento, tanto che una sua biografia era stata prevista da Roberto Aloi per il
"Dizionario illustrato dei pittori, scultori e incisori italiani moderni", che doveva essere edito da Giovanni Scheiwiller nel 1948/49 e poi mai pubblicato
Teoria e politica della storia in Marx

Implementation, Parameters Calibration and Field Validation of a Closed Loop Performance Monitoring System
No full textThe paper illustrates the main features of a performance monitoring system which supervises more than 1200 loops of refinery plants. The system analyses data recorded by the DCS during routine operations and originates verdicts about the performance of control loops; also, indications of low performance causes and different strategies to adopt (retuning, valve maintenance, upstream actions) are given. First, the architecture of the system is illustrated, and characteristics of modules which accomplish different tasks of data acquisition and transfer, system configuration and priority assignment, performance analysis and verdicts emission, database query and operator support, are described. A synthesis of main techniques adopted in the system for stiction detection, process identification and performance evaluation, is also reported. The procedure for calibration of threshold values of key parameters, in order to match verdicts issued automatically by the system with operators evaluations and to avoid false alarms, is also discussed. Examples of results achieved from field validation are then presented, with illustration of loop performance before and after actions suggested by the monitoring system
Thomas Hobbes e la cristianità del Leviatano. Sulla duplice funzione della sovranità
No full textThis essay proposes an interpretation of the Christian theological discourse developed in
Thomas Hobbes’s Leviathan in order to show: 1) its theoretical-systematic value in the
definition of the political form, that is, of the conceptual articulation that sustains the
sovereignty device; 2) its complementarity to the performative trait of the Hobbesian
anthropological discourse, that is, to the determination of the profile of a specific form of
life, adapted to the sovereign order because capable of reproducing industriously within it
and which is, at the same time, the primary product of that order. This interpretation
shows that the Christian Commonwealth is the complete realization of the Hobbes’s
anthropological-political project
Utopia e possibilità oggettivo-reale in Ernst Bloch
No full textThe essay analyses Ernst Bloch’s concept of utopia, which refers primarily to the transformative content of reality and is declined according to the category of objective-real possibility. Against any reading of the utopian content as a fantastic and abstract transgression from reality, the concrete utopia becomes in Bloch a rigorous philosophical principle that orients the possible mediation of utopian desires and thoughts according to real tendencies
