Comparison between simulated and observed LHC beam backgrounds in the ATLAS experiment at E beam =4 TeV

2018

Results of dedicated Monte Carlo simulations of beam-induced background (BIB) in the ATLAS experiment at the Large Hadron Collider (LHC) are presented and compared with data recorded in 2012. During normal physics operation this background arises mainly from scattering of the 4 TeV protons on residual gas in the beam pipe. Methods of reconstructing the BIB signals in the ATLAS detector, developed and implemented in the simulation chain based on the FLUKA Monte Carlo simulation package, are described. The interaction rates are determined from the residual gas pressure distribution in the LHC ring in order to set an absolute scale on the predicted rates of BIB so that they can be compared qua…

Causal Models for Monitoring University Ordinary Financing Fund

2012

Recently iterated decreasing government transfers and an increasing proportion of budget allotted basing on competitive performances, took Italian Universities started struggling with competition for funds, in particular for the University Ordinary Financing Fund (FFO). Aim of this paper is monitoring variables responsible for FFO indicators, where monitoring means: describing, analysing retrospectively, predicting and intervening on variables responsible for indicators. All this aims can be achieved by statistical techniques that should be theoretically equipped with the distinction between predicting under observation and predicting under intervention, in order to provide correct answers …

Biogeography and ecology of geographically distant populations of sibling Cryptocephalus leaf beetles

2020

Different populations of two closely related species, Cryptocephalusflavipes and C. bameuli, from western (Alps, Apennines and Pyrenees) and central Europe (Poland, Ukraine and Pannonia) were analysed. On the basis of DNA sequences from two genes, cox1 and ef1-alpha, distinctiveness of both species was confirmed. Nevertheless, possible hybrids were identified in Carpathian mountains. We found a significant genetic differentiation among populations of C. flavipes and C. bameuli from distant regions but a high genetic similarity between populations of C. bameuli from north and south of the Carpathians. Demographic estimates suggest a past population expansion in the case of C. bameuli and a r…

Molecular phylogeny, biogeographic history, and evolution of cave-dwelling taxa in the European harvestman genusIschyropsalis(Opiliones: Dyspnoi)

2015

Abstract We estimated a multigenic molecular phylogeny and reconstructed biogeographic history for the European harvestman genus Ischyropsalis C.L. Koch 1839 (Dyspnoi). To reconstruct historical biogeographic patterns we conducted an algorithmic VIP analysis which revealed patterns consistent with a vicariance-dominated history. The existing morphology-based systematic framework for Ischyropsalis is mostly inconsistent with molecular phylogenetic results, and a new informal system is established that recognizes three main clades and several sub-clades. Species-level analyses revealed two non-monophyletic species (I. pyrenaea Simon 1872 and I. luteipes Simon 1872); subspecies of I. pyrenaea …

2020

The scope of the Progress in Paper Physics Seminar is to discuss the broad scope of physical properties of paper, paperboard and new cellulose containing materialas. The program contain presentations reporting on the latest experimental, theoretical and computational developments. The three invited plenary speakers aim at bringing industry and academia together for in-depth discussions on selected topics in paper physics the potential impact on industry. The selected 37 oral presentations and 12 poster presentations provide opportunity to improve scientific knowledge and explore the latest outcomes and trends in the field. nonPeerReviewed

Bright Cities and City Information Modeling

2019

The increasing urbanization and above all the increasing demand for more efficiency in energy consumption and in the management of natural resources makes ever more urgent to tackle the construction of buildings and the planning of cities in an innovative and sustainable way. In this perspective, some research lines have emerged referring to the concepts of smart, intelligent, and green/sustainable buildings. Starting from this analysis, the article aims to highlight how it is possible to synthesize both the environmental quality aspects and the integrated control of a building in the concept of bright green buildings, and how thus a wider conceptual reference framework is necessary: identi…

Green Roofs as Effective Tools for Improving the Indoor Comfort Levels of Buildings—An Application to a Case Study in Sicily

2020

In the line of pursuing better energy efficiency in human activities that would result in a more sustainable utilization of resources, the building sector plays a relevant role, being responsible for almost 40% of both energy consumption and the release of pollutant substances in the atmosphere. For this purpose, techniques aimed at improving the energy performances of buildings&rsquo

An agile process modelling approach for BIM projects

2016

International audience; In the domain of Building Information Modelling (BIM), the open standardisation of methods for product and process modelling is undertaken by the buildingSMART association. Currently, buildingSMART recommends the use of Business Process Model and Notation (BPMN) for creating process models in Information Delivery Manuals (IDMs). This paper argues that BPMN is closely linked to the waterfall nature of today’s BIM projects, leading to a number of issues including long project durations, lack of stakeholder involvement, and disconnect of processes and data. Subject-oriented Business Process Management (S-BPM) is introduced as an alternative modelling approach for IDMs, …
