Innovative thermoeconomic diagnosis of multiple faults in air conditioning units: Methodological improvements and increased reliability of results
2013
Abstract Thermoeconomic faults diagnosis of air conditioning units is a pioneeristic approach to detect single or multiple faults and quantify their impact in terms of additional energy consumption. The poor reliability of conventional thermoeconomic approaches has been limiting the interest for practical applications of this technique. In this paper an improved thermoeconomic diagnosis is proposed and applied to a reference 120 kW c air-cooled air conditioning system; a simulator is used to evaluate thermodynamic data under normal and faulty conditions. Four faults are individually or simultaneously imposed: fouling at condenser and evaporator, refrigerant undercharge and compressor valve …

Le rappresentazioni dell'alterità nelle cerimonie carnevalesche. Forme e funzioni
2012
Nel saggio viene riesaminata, attraverso puntuali riferimenti alla vasta letteratura sull’argomento, una specifica modalità di guardare alle “epifanie dell’alterità”, essenzialmente ma non esclusivamente “in maschera”, così come si manifestano/manifestavano all’interno delle cerimonie carnevalesche euro-mediterranee e ci si propone di misurarne l’attuale efficacia euristica. Viene riesaminato cioè un indirizzo interpretativo essenzialmente di stampo storicistico-fenomenologico, che tende a attribuire ai mascherati il ruolo di rappresentanti dei morti, variamente riproposto entro filoni di studio di lunga durata e cui lo stesso autore ha fatto costante riferimento nei suoi lavori, direttamen…

Measurement of cloud point temperature in polymer solutions.
2013
A temperature-controlled turbidity measurement apparatus for the characterization of polymer solutions has been instrumented and set up. The main features are the coupled temperature-light transmittance measurement and the accurate temperature control, achieved by means of peltier cells. The apparatus allows to measure cloud point temperatures by adopting different cooling protocols: low rate for quasi-equilibrium measurements and high rate for detect kinetic effects. A ternary polymeric solution was adopted as case study system showing that cooling rate affects the measured cloud point temperature.
Enhanced thermoelectric performance of PEDOT with different counter-ions optimized by chemical reduction
2014
This work reports on the synthesis of the intrinsically conducting polymer poly(3,4-ethylenedioxythiophene) (PEDOT) doped with several counter-ions, ClO4, PF6 and bis(trifluoromethylsulfonyl)imide (BTFMSI), by electro-polymerization and its thermoelectric properties. We show that, depending on the counter-ion size, the thermoelectric efficiency of PEDOT can be increased up to two orders of magnitude. A further chemical reduction with hydrazine optimizes the power factor (PF). By changing the counter-ions, we were able to increase the electrical conductivity (σ) of PEDOT by a factor of three, while the Seebeck coefficient remains at the same order of magnitude in the three polymers. The best…
A Quantitative Analysis of the Thermoelastic Effect in CFRP Composite Materials
2010
: In this study the thermoelastic signal from carbon fibre-reinforced plastic (CFRP) laminates is investigated. A comparison between the theoretical and experimental values of the thermoelastic signal is reported, with the theoretical predictions obtained from two different quantitative models. These models are based on the classic thermoelastic effect law extended to the case of orthotropic materials (by using the mesomechanical or bulk approach), and the modified law assuming that the surface resin-rich layer behaves as a strain witness of the laminate. It is found that the theoretical predictions of the two models can be strongly and differently influenced by the intrinsic orthotropy of…
Sono arrabbiato e sono antropologo. Blues lévi-straussiano su un’emozione furente
2017
In questo saggio, mi ‘lascio andare’, volutamente e direttamente, nel loro intreccio d’insieme e interrelato, alle seguenti questioni: la semantica della rabbia in un contesto vissuto personalmente, l’uso di una scrittura meno convenzionale ai fini di un maggior scavo interiore, l’esemplificazione letteraria come contrappunto e verifica tematica ed esistenziale, la possibilità di descrizione del tempo e dello spazio nell’arco stesso della prossimità del vissuto, il contrasto tra ‘forme di vita concepite per fini da raggiungere’ e ‘forme di vita concepite nella liminalità’, la riflessione sull’oscillazione autoriale di un Lévi-Strauss preso tra strutturalismo e soggettivismo, la riformulazio…
