Diversità nei luoghi: condizioni da esplorare
2012
Contributo scientifico sulla diversità dei luoghi in relazione alla definizione di “Progetto” quale connotazione imprescindibile della sua natura disciplinare nell’ambito della ricerca Turismo Relazionale Integrato, per il progetto regionale e internazionale MOTRIS II. Curato dal Collegio Universitario ARCES con il supporto scientifico del Centro Ricerche nuovo Umanesimo Edoardo Caracciolo (CRUEC).
Unconventional application of Image Correlation techniques on Biomaterials and cardiovascular applications
2022
Image Correlation techniques are increasing in popularity and are now suitable to investigate complex structural and fluid-dynamics of cardiovascular systems. These approaches operate through a digital correlation of a pair of images to determine physical quantities of complex systems. In this thesis, their application to the mechanical characterisation of complex biomaterials (Nitinol and soft materials), and the characterisation of complex biofluid-dynamics was investigated, with the aim to analyse their reliability and enhance their accuracy and field of application. Digital Image Correlation, supported by Infrared Thermography, was used to achieve a more in depth understanding of the me…
Thermomechanical Characterization of Polylactic Acid and Composites
2018
This paper presents the experimental tests for the thermomechanical characterization of biopolymer polylactic acid, and its composites with beech flour or with nanoreiforcement of modified montmorillonite, in order to evaluate any applicability in the automotive sector. Tests of torque and traction are executed for the mechanical characterization and the results comparison; dynamical tests are executed for the thermomechanical characterization, determining the elastic modulus and loss factor versus the actual temperature.
Caratterizzazione termomeccanica dell’acido polilattico e due suoi compositi
2018
Questa memoria presenta i test sperimentali per la caratterizzazione termomeccanica del biopolimero acido polilattico e dei suoi compositi con farina di faggio o con nanorinforzo di montmorillonite modifcata, per uno studio di applicabilità nel settore automobilistico. Per la caratterizzazione meccanica e il confronto dei risultati vengono eseguiti prove di coppia e di trazione; i test dinamici vengono eseguiti per la caratterizzazione termomeccanica, determinando il modulo elastico e il fattore di perdita rispetto alla temperatura effettiva. This paper presents the experimental tests for the thermomechanical characterization of biopolymer polylactic acid, and its composites with beech flour…
QUEL CHE RESTA NEGLI OCCHI:LA SCENOGRAFIA COME IBRIDO D'ARCHITETTURA

La Palermo di Vincenzo Melluso
2017
Ci sono voluti 3.000 anni per fare Palermo. A compierla sono stati in molti: un’umanità di costruttori sospinta in avanti da valori e ragioni mutevoli, differenti, e che lì, approdata a un certo punto lì, in un anfiteatro immaginato dalla natura, ha iniziato a costruire. Questo sovrapporsi arriva a chi ci vive oggi, in forma esplosiva. Non serve disporre di uno sguardo attrezzato, quello che sa indagare la condizione insediativa, la varietà dei caratteri, la funzionalità strutturale degli incroci tra spazi urbani e privati: camminate per Palermo un quarto d’ora e lo vedrete. It took 3,000 years to build Palermo. Its completion involved many: an entire population of constructors driven by vo…
Measurement of edge residual stresses in glass by the phase-shifting method
2011
Abstract Control and measurement of residual stress in glass is of great importance in the industrial field. Since glass is a birefringent material, the residual stress analysis is based mainly on the photoelastic method. This paper considers two methods of automated analysis of membrane residual stress in glass sheets, based on the phase-shifting concept in monochromatic light. In particular these methods are the automated versions of goniometric compensation methods of Tardy and Senarmont. The proposed methods can effectively replace manual methods of compensation (goniometric compensation of Tardy and Senarmont, Babinet and Babinet–Soleil compensators) provided by current standards on th…
Review of RGB photoelasticity
2015
Abstract Automatic methods of photoelasticity have had a significant progress with the development of automatic acquisition and image processing methods. This article concerns RGB photoelasticity, which allows the determination of the photoelastic retardation using, usually, a single acquisition of the isochromatic fringes in white light by a colour camera. In particular, the article presents an overview of the main characteristics of RGB photoelasticity that is influence of the quarter-wave plate error, number of acquisitions, type of light source, determination of low and high fringe orders, methods for searching the retardation, scanning procedures, calibration on a material different fr…
Photoelastic Analysis of Edge Residual Stresses in Glass by Automated “Test Fringes” Methods
2011
Since the glass is a birefringent material, the analysis of residual stress in glass is usually carried out by means of photoelastic methods. This paper considers the automation of the “test fringes” method which is based on the use of a Babinet compensator or of a beam subjected to bending. In particular, two automated methods are proposed: the first one is based on the use of the centre fringe method in monochromatic light and the second one is based on the use of RGB photoelasticity in white light. The proposed methods have been applied to the analysis of membranal residual stresses in some tempered glasses, showing that they can effectively replace manual methods of photoelastic analysi…
