Tecnica e poetica. Il calcestruzzo armato nell'opera di Giuseppe Samonà

2021

Elemento distintivo e imprescindibile dell’opera di Giuseppe Samonà è l’utilizzo del calcestruzzo armato, come forma tecnica ma anche poetica, alla base del carattere estetico-figurativo delle sue architetture. Il differente utilizzo del calcestruzzo - spesso in forma monolitica, ricercando la continuità materica e spaziale tra interno ed esterno - deriva dal rapporto tipologia-morfologia: al prevalere dell’uno cambia il modo in cui il materiale viene impiegato e pertanto anche il linguaggio che ne deriva secondo un rapporto causa-effetto.

COMPLEXITY, NOISE AND QUANTUM INFORMATION ON ATOM CHIPS

2008

The realization of quantum logic gates with neutral atoms on atom chips is investigated, including realistic features, such as noise and actual experimental setups.

Isotropic–isotropic phase separation in mixtures of rods and spheres: Some aspects of Monte Carlo simulation in the grand canonical ensemble

2008

Abstract In this article we consider mixtures of non-adsorbing polymers and rod-like colloids in the isotropic phase, which upon the addition of polymers show an effective attraction via depletion forces. Above a certain concentration, the depletant causes phase separation of the mixture. We performed Monte Carlo simulations to estimate the phase boundaries of isotropic–isotropic coexistence. To determine the phase boundaries we simulated in the grand canonical ensemble using successive umbrella sampling [J. Chem. Phys. 120 (2004) 10925]. The location of the critical point was estimated by a finite size scaling analysis. In order to equilibrate the system efficiently, we used a cluster move…

The SISCone jet algorithm optimised for low particle multiplicities

2011

The SISCone jet algorithm is a seedless infrared-safe cone jet algorithm. There exists an implementation which is highly optimised for a large number of final state particles. However, in fixed-order perturbative calculations with a small number of final state particles, it turns out that the computer time needed for the jet clustering of this implementation is comparable to the computer time of the matrix elements. This article reports on an implementation of the SISCone algorithm optimised for low particle multiplicities.

Conjectural reconstruction from archive drawings: methodological aspects

2018

The digital reconstruction of architectural projects starting from archive sources is a well established disciplinary application useful for the study and analysis of architecture and its relations with the historical context as well as for the representation of volumes and spaces not visible in the original documents. Given the importance recognized to these operations which inevitably involve processes of hermeneusi we propose methodological guidelines for the drafting a protocol limiting arbitrariness as much as possible. The analysis was carried out on three projects by Giuseppe Damiani Almeyda (Capua 1834 - Palermo 1911), Ernesto Basile (Palermo 1857-1932) and Salvatore Benfratello (Pa…

Argumentation graphs with constraint-based reasoning for collaborative expertise

2018

International audience; Collaborative processes are very important in telemedicine domain since they allow for making right decisions in complex situations with multidisciplinary staff. When modelling these collaborative processes, some inconsistencies can appear. In semantic modelling (conceptual graphs), these inconsistencies are verified using constraints. In this work, collaborative processes are represented using an argumentation system modelled in a conceptual graph formalism where inconsistencies could be particular bad attack relation between arguments. To overcome these inconsistencies, two solutions are proposed. The first one is to weight the arguments evolving in the argumentati…

Trasferimenti tecnologici nella Sicilia d’età moderna: l'impiego del mattone a “cortina”

2016

In Sicilia, nel contesto di quella che è stata definita la civiltà della pietra, e tra i laboratori della stereotomia medioevale nel Mediterraneo, il ricorso al laterizio e alla tecnica costruttiva che l’impiego di un materiale “artificiale” comporta, ha generato in età moderna fabbriche che hanno operato uno scarto rispetto alla tradizione fino a produrre una nuova tradizione. La serie di casi che sono segnalati in questo contributo indicano come sia stata spesso la mobilità di alcuni maestri “forestieri” a spiegare l’introduzione, l’attecchimento e la fortuna dell’impiego del mattone a faccia vista, o altrimenti detto a “cortina”, nel cantiere siciliano d’età moderna. In Sicily, as a part…

Le consulte collettive nell'architettura siciliana tra tra XVI e XVII secolo

2015

Il contributo esamina alcuni casi di " consulte" di natura costruttiva avvenute nell'architettura siciliana tra XVI e XVII secolo, attraverso la documentazione ad oggi nota. Quello che emerge dal confronto di una serie di documenti è la continuità di certe formule, come nella stima dei costi, mentre le differenze sono evidenti nelle consulenze svolte. Ci sono ad esempio cantieri (come per esempio quello relativo alla chiesa madre di Piazza) dove il processo è frequente mentre ce ne sono altri dove le consulte appaiono discontinue nel tempo (per esempio nella cattedrale di Agrigento). Durante il XVII sussiste anche un divario tra perizie affidate ad architetti e quelle compilate da maestri c…

Recent studies on the economic dimensions of sports and physical activity in Germany have revealed that sport-related tourism is one of the important contributors to private household consumption. Due to a lack of representative and large-scale data sets, this topic has never been displayed in detail before. By using computer assisted telephone and web interviews, we collected a total data set of n=19,396 persons living in Germany. The expenditures for active sport tourism were isolated, which is understood as travelling to take part in different sporting activities. Data are provided on the overall spending of German households for sport trips, with skiing (€ 3.4 bn) and scuba diving (€ 2.…

Perceived-Value-driven Optimization of Energy Consumption in Smart Homes

2020

Residential energy consumption has been rising rapidly during the last few decades. Several research efforts have been made to reduce residential energy consumption, including demand response and smart residential environments. However, recent research has shown that these approaches may actually cause an increase in the overall consumption, due to the complex psychological processes that occur when human users interact with these energy management systems. In this article, using an interdisciplinary approach, we introduce a perceived-value driven framework for energy management in smart residential environments that considers how users perceive values of different appliances and how the us…
