Form, figure and landscape for nature in the city.
2014
The article “Form, Figure and Landscape for Nature in the city” describes, through a sequence of steps, the urban and territorial threshold that give structure to the Piacenza southern area. It analyzes in detail the elements that define three “rooms” at different scales: - at the territorial scale, the farmhouses define a system of elements as focal point overlooking the agricultural surface, interpreted as background; - at the urban scale, the reconfiguration of the morphological tissue of the INA Casa neighborhoods allows to read a district itself as a specific “room” inside Piacenza urban fabric; - at the architectural scale, the gardens of interior courtyards of via Francigena building…
The Configuration of Space Through Architecture in the Thinking of Gadamer
2017
Although Gadamer stresses the importance of temporality, historicity and tradition, the aim of this contribution is to underline the uniqueness of architecture in Truth and Methods’ investigation relative to the essence of a work of art. The uniqueness of architecture for Gadamer lies not only in the fact that it gives space for the expression of all other kinds of artworks; a building has to be to understood as self-sufficient and as autarchic, but also as inscribed in the concrete historical life. A further aspect of the uniqueness of architecture originates in the fact that a building determines our way of life or our dwelling even in a political sense.
Hilbert–Schmidt speed as an efficient figure of merit for quantum estimation of phase encoded into the initial state of open n-qubit systems
2021
AbstractHilbert–Schmidt speed (HSS) is a special type of quantum statistical speed which is easily computable, since it does not require diagonalization of the system state. We find that, when both HSS and quantum Fisher information (QFI) are calculated with respect to the phase parameter encoded into the initial state of an n-qubit register, the zeros of the HSS dynamics are actually equal to those of the QFI dynamics. Moreover, the signs of the time-derivatives of both HSS and QFI exactly coincide. These findings, obtained via a thorough investigation of several paradigmatic open quantum systems, show that HSS and QFI exhibit the same qualitative time evolution. Therefore, HSS reveals its…
Questue e figure vicariali in area euromediterranea
2015
Bambini, poveri, becchini, sagrestani – nell’orizzonte ideologico delle culture tradizionali di area euromediterranea – condividono statuto e funzioni simboliche: sono figure vicariali dei defunti nonché mediatori mitici tra il mondo dei vivi e quello dei morti. Nell’intervallo temporale che si sussegue dall’equinozio autunnale a quello primaverile, tali figure erano – e in alcuni contesti, come quello sardo, sono tutt’oggi – protagoniste di questue, nell’ambito delle quali l’offerta materiale e simbolica dei doni sanciva, rinnovandola, l’unità ideale tra sfera umana ed extraumana. Nel presente lavoro, la documentazione folklorica e l’indagine etnografica tentano di chiarire il significato …
Long-Term Stability of (Ti/Zr/Hf)CoSb1−xSnxThermoelectric p-Type Half-Heusler Compounds Upon Thermal Cycling
2015
The effect of thermal cycling upon the thermoelectric performance of state-of-the-art p-type half-Heusler materials was investigated and correlated with the impact on the structural properties. We simulated a heat treatment of the material similar to actual applications in the mid-temperature range, such as occurs during the energy conversion from an automotive exhaust pipe. We compared three different compositions based on the (Ti/Zr/Hf)CoSb1−xSnx system. The best and most reliable performance was achieved using Ti0.5Hf0.5CoSb0.85Sn0.15, which reached a maximum figure of merit ZT of 1.1 at 700 °C. The intrinsic phase separation and resulting microstructuring, which are responsible for the …
«History’s stained canvas»: Uses and appropriations of medieval past in Enlightenment Historiography. The case of Peter «the cruel»
2020
The aim of this paper is to explore the political meanings of the medieval past in the historical understanding of individuals in the 18th century. Beyond the familiar Gothic myth, I will focus on the multilayered image of the monarch Peter of Castile (1334–1369), considered cruel, lustful and passionate in the eyes of enemies and historians. The aim is to analyse the different attitudes towards and uses of this historical figure (one that was quite problematic given the cultural values of the period), ranging from the most negative of connotations to the most passionate of defences and including some more ambiguous stances. For this analysis, I will explore certain Enlightenment debates th…

Le ceramiche attiche a figure nere dallo scarico di Grotta Vanella a Segesta: primi dati da una revisione
2017
Questo articolo esamina i frammenti di vasi attici a figure nere della cosiddetta Grotta Vanella deposito a Segesta, costituito da materiali scaricati dalla cima del Monte Barbaro, a nord Acropoli. Vengono indicate le forme, vengono esaminati i temi e le funzioni figurative delle navi e la distribuzione di alcuni tipi e classi di vasi in diverse fasi cronologiche. In assenza di dati stratigrafici, i dating sono stati stabiliti sulla base dell'attribuzione dei frammenti ai workshop o gruppi di pittori noti e, quando possibile, confrontati con reperti provenienti da contesti archeologici piuttosto datato. Per quanto riguarda i temi figurativi, sebbene il materiale frammentario abbia limitato …
Vasi attici a figure rosse da Segesta: i materiali dello scarico di Grotta Vanella
2020
Lo studio si propone di fornire un quadro di riferimento delle importazioni di vasi figurati attici a Segesta, analizzando artisti, forme e iconografia di questa produzione. I frammenti di vasi attici a figure rosse provengono dal cosiddetto deposito della Grotta Vanella a Segesta, che consiste di materiali scaricati dalla cima del Monte Barbaro, l'Acropoli del Nord. L'esame dei reperti ceramici ha mostrato una buona varietà di tipologie formali e la prevalenza di specifiche categorie funzionali dedicate al consumo di vino, che si riflette in altre classi ceramiche. La cronologia è stata stabilita sull'attribuzione di frammenti a laboratori o gruppi di pittori e dal confronto con reperti pr…
Exploiting the optical quadratic nonlinearity of zinc-blende semiconductors for guided-wave terahertz generation: A material comparison
2010
We present a detailed analysis and comparison of dielectric waveguides made of CdTe, GaP, GaAs and InP for modal phase matched optical difference frequency generation (DFG) in the terahertz domain. From the form of the DFG equations, we derived the definition of a very general figure of merit (FOM). In turn, this FOM enabled us to compare different configurations, by taking into account linear and nonlinear susceptibility dispersion, terahertz absorption, and a rigorous evaluation of the waveguide modes properties. The most efficient waveguides found with this procedure are predicted to approach the quantum efficiency limit with input optical power in the order of kWs.
