Implementation and performance of the ATLAS second level jet trigger
2008
ATLAS is one of the four major LHC experiments, designed to cover a wide range of physics topics. In order to cope with a rate of 40 MHz and 25 interactions per bunch crossing, the ATLAS trigger system is divided in three different levels. The first one (LVL1, hardware based) identifies signatures in 2 microseconds that are confirmed by the the following trigger levels (software based). The Second Level Trigger (LVL2) only looks at a region of the space around the LVL1 signature (called Region of Interest or ROI), confirming/rejecting the event in about 10 ms, while the Event Filter (Third Level Trigger, EF) has potential full event access and larger processing times, of the order of 1 s.

Connessioni e stratificazioni della forma urbana. Le tracce degli anfiteatri romani e le loro risignificazioni
2020
Starting from the survey of the remains of Termini Imerese Roman Amphitheater and considering both its virtual reconfiguration and the architectural events that have seen the succession of different urban stratifications and re-significations, we have concentrated our interest on the cases that have determined the changes in shape and the archaeological sedimentations of some amphitheatres in Italy and Europe. From these preliminary operations the investigation work was carried out on Palermo, wanting to verify - through the survey and the redrawing of the urban fabric - the compatibility of the most recent hypotheses of location of the buildings for spectacles in the Panormus of the Roman …
Purity and Dirt as Social Constructions: Environmental Health in an Urban Shantytown of Lagos
2005
The focus of this article, on everyday life management, emerges from a theoretical discussion about culturally specific attitudes to environmental health. Local perceptions of purity and dirt in an urban shantytown of Lagos, Nigeria, are examined through a case study of the Amukoko urban district. The qualitative data is from two fieldwork phases carried out in 1998 and 2001 in Lagos, consisting of eleven in-depth interviews, eight focus group discussions and participatory observations among Yoruba women and men. In different communities, perceptions of purity and dirt are not self-evident in terms of their meaning, but reflect the commonly shared values and moral codes of the community. Ou…
Luoghi urbani scomparsi e architetture mai realizzate nella riconfigurazione 3D del Rione Conceria di Palermo
2018
L'oggetto di studio è lo scomparso Rione Conceria all'interno del Centro Storico di Palermo. È una vasta area urbana, che si estende lungo la Via Maqueda, Via Roma, Corso Vittorio Emanuele e Via Bandiera, che storicamente faceva parte di un unico sistema urbano che cuciva il mercato del Capo con il Mercato della Vucciria. Le operazioni urbanistiche del secolo scorso (il taglio di via Roma, il il progetto di riorganizzazione dell'intero rione, la costruzione della Galleria delle Vittorie) hanno cancellato quasi definitivamente sia le sue presenza architettoniche che l'impianto del suo tessuto viario. The object of study is the disappeared Rione Conceria inside the Historical Center of Palerm…
Housing Affordability in Metropolitan Areas. The Application of a Combination of the Ratio Income and Residual Income Approaches to Two Case Studies …
2017
Housing affordability problems have become more serious over the course of the last few decades and are now also affecting the middle-class, despite the fall in prices on the housing market. This study proposes a methodology to assess threshold-income as an index for measuring housing affordability by applying a combination of the ratio income and residual income approaches. The methodology is applied to two particular areas of Sicily in Italy as case studies consisting of medium-size metropolitan areas located in a less developed European region. The areas have been chosen on the basis of their different territorial structure: a polarized area that comprises a high-density city centre and …
Giustizia ambientale e recupero delle aree verdi: il caso di Palermo
2021
L’urban shrinkage è diventata una questione centrale tanto nel dibattito scientifico quanto nell’agenda politica di diverse città europee. Secondo i dati EUROSTAT (2019), circa il 40% delle città europee con più di 200.000 abitanti stanno perdendo popolazione; una contrazione che si esplicita maggiormente, sotto il profilo spaziale, in una progressiva sottoutilizzazione del patrimonio edificato, così come nel contestuale incremento di aree e terreni in stato di abbandono. In questo quadro controverso di mutazione strutturale della città, così come l’abbiamo conosciuta, le politiche urbane alla prova in Europa tentano di declinare la decrescita quale occasione strategica di investimento sull…

A Composition Approach to Design of Educational Animations
2017
International audience; The educational effectiveness of conventionally designed animations that portray complex, unfamiliar subject matter in a behaviorally realistic fashion too often falls well short of expectations. Previous research indicates that the veridical dynamic properties of these comprehensive animations make a major contribution to their lack of effectiveness. Due to these dynamics, there is a substantial mismatch between the processing demands these animations impose on learners and the characteristics of the human information processing system. As a result, the quality of the mental models that learners are able to construct is compromised. Interventions intended to improve…
Kształtowanie się ustroju II Rzeczpospolitej w aspekcie zrównoważonego rozwoju
2018
W artykule przedstawiono proces kształtowania się ustroju II Rzeczpo-spolitej i pokładanych nadziei na zrównoważony rozwój kraju. Zarysowano tradycjępolskiego parlamentaryzmu i wskazano na jego odrębność względem parlamentary-zmów innych krajów europejskich. Do tradycji tej usiłowało nawiązać odradzające siępo zaborach państwo polskie, przystosowując ją do struktury prawnej nowożytnego państwa liberalno-demokratycznego. Wejście II Rzeczpospolitej do grona państw po-siadających liberalno-demokratyczną konstytucję nie oznaczało, automatycznego za warstwą prawną, przeniesienia struktury społecznej, ekonomicznej i mentalnej. W centrum rozważań znalazła się także Konstytucja Marcowa oraz relacje…
A new project management approach for R&D software projects in the automotive industry - continuous V-model
2017
Most current work activities in R&D centres are innovative and dynamic, with project management acting as the discipline that governs them. The improvement of PM methods has become a necessity due to the following main factors: classical methodologies are increasingly difficult to apply, cutbacks in project duration are requested by organisations and customers, demands for product quality are continuously expanding. The paper examines how PM concepts are used in developed R&D projects, based on the V-model approach. It also introduces an enhanced new approach called Continuous V-model - CVM, based on agile concepts. The model has been applied on a real automotive R&D project and the resulte…
