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.
A system based on neural architectures for the reconstruction of 3-D shapes from images
1991
The connectionist approach to the recovery of 3-D shape information from 2-D images developed by the authors, is based on a system made up by two cascaded neural networks. The first network is an implementation of the BCS, an architecture which derives from a biological model of the low level visual processes developed by Grossberg and Mingolla: this architecture extracts a sort of brightness gradient map from the image. The second network is a backpropagation architecture that supplies an estimate of the geometric parameters of the objects in the scene under consideration, starting from the outputs of the BCS. A detailed description of the system and the experimental results obtained by si…
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…
Electricity Consumption Analysis of Tertiary Buildings: An Empirical Approach for Two University Campuses
2020
An empirical approach for the analysis of energy consumption of existing buildings of the tertiary sector is presented in this study. It allowed the organization and management of large amounts of data according to different timeframes and helped to focus on leading issues about energy uses, and dealt with compatibility with tariff structure. The analysis method, which implied a powerful graphical representation of the results, allowed us to detect critical issues in electricity energy management for public buildings and improve their energy performance. Furthermore, the authors proposed a set of electricity consumption indexes (ECIs) that gave useful insight into the main hotspots. The bas…
