QCD NLO with Powheg matching and top threshold matching in WHIZARD
2016
We present the status of the automation of NLO processes within the event generator WHIZARD. The program provides an automated FKS subtraction and phase space integration over the FKS regions, while the (QCD) NLO matrix element is accessed via the Binoth Les Houches Interface from an externally linked one-loop program. Massless and massive test cases and validation are shown for several e+e- processes. Furthermore, we discuss work in progress and future plans. The second part covers the matching of the NRQCD prediction with NLL threshold resummation to the NLO continuum top pair production at lepton colliders. Both the S-wave and P-wave production of the top pair are taken into account in t…
Proportions. Science, Musique, Peinture et Architecture
2012
Le langage des proportions est un langage de comparaison. Outil scientifique, il met en relation grandeurs mathématiques ou physiques (deux cercles, deux mouvements, deux sons, etc.). Pour autant, son application ne se restreint pas au seul champ des mathématiques. Erigé en principe philosophique par le principe de comparaison qui le sous-tend, il déploie tout son potentiel analogique en devenant langage constructeur d'harmonie. La théorie des proportions s'ouvre ainsi sur un vaste champ de relations qui définissent canons et règles de beauté dans les diverses disciplines artistiques. S'intéresser aux proportions signifie donc s'intéresser à tous les domaines du savoir. Mais comment aborder…
Qualitative analysis of housing demand using Google trends data
2019
Big data analytics often refer to the breakdown of huge amounts of data into a more readable and useful format. This study utilises Google Trends big data as a proxy for an analysis of housing demand. We employ a qualitative method (fuzzy set/Qualitative Comparative Analysis, fsQCA), instead of a quantitative method, for our estimate and forecast. The empirical results show that fsQCA successfully forecasts seasonal time series, even though the dataset is small in size. Our findings fill the gap in the qualitative and time series forecasting literature, and the forecasting procedure herein also offers a good standard for industry.
L’insegnamento della progettazione architettonica: Una comparazione tra Italia e Spagna
2019
L’organizzazione temporale dei corsi di progettazione architettonica ha un ruolo cardine nell’intero percorso formativo. Il saggio propone una comparazione tra gli strumenti, le metodologie e le modalità di insegnamento del progetto di architettura in Italia e Spagna, più specificatamente tra l’Università di Palermo e la Universitat Politècnica de València, riportando alcuni esiti dei corsi nelle due Università, con particolare riferimento alle forme dell’abitare domestico, e alla poetica dello spazio interno.
Time interaction with two spatial dimensions: from left/right to near/far
2022
In this study, we explored the time and space relationship according to two different spatial codings, namely, the left/right extension and the reachability of stimulus along a near/far dimension. Four experiments were carried out in which healthy participants performed the time and spatial bisection tasks in near/far space, before and after short or long tool-use training. Stimuli were prebisected horizontal lines of different temporal durations in which the midpoint was manipulated according to the Muller-Lyer illusion. The perceptual illusory effects emerged in spatial but not temporal judgments. We revealed that temporal and spatial representations dynamically change according to the ac…
Some Remarks about Product Spaces
2018
Summary This article covers some technical aspects about the product topology which are usually not given much of a thought in mathematics and standard literature like [7] and [6], not even by Bourbaki in [4]. Let {Ti}i∈I be a family of topological spaces. The prebasis of the product space T = ∏ i∈I Ti is defined in [5] as the set of all π −1 i (V) with i ∈ I and V open in Ti . Here it is shown that the basis generated by this prebasis consists exactly of the sets ∏ i∈I Vi with Vi open in Ti and for all but finitely many i ∈ I holds Vi = Ti . Given I = {a} we have T ≅ Ta , given I = {a, b} with a≠ b we have T ≅ Ta ×Tb . Given another family of topological spaces {Si}i∈I such that Si ≅ Ti fo…
Anonymization as homeomorphic data space transformation for privacy-preserving deep learning
2021
Industry 4.0 is largely data-driven nowadays. Owners of the data, on the one hand, want to get added value from the data by using remote artificial intelligence tools as services, on the other hand, they concern on privacy of their data within external premises. Ideal solution for this challenge would be such anonymization of the data, which makes the data safe in remote servers and, at the same time, leaves the opportunity for the machine learning algorithms to capture useful patterns from the data. In this paper, we take the problem of supervised machine learning with deep feedforward neural nets and provide an anonymization algorithm (based on the homeomorphic data space transformation),…

Siracusa e la Sicilia nel III secolo a.C.: problemi conoscitivi e proposte di lettura dei fenomeni urbanistici e architettonici
2017
L’evoluzione sotto il profilo urbanistico e architettonico delle città di Sicilia nel III secolo a.C. può essere compresa solo a partire da un esame delle evidenze di Siracusa, la maggiore città dell’Occidente greco-ellenistico e capitale di un regno che sotto Agatocle e soprattutto sotto Ierone II vede un prodigioso sviluppo non solo per l’estensione dell’area urbana, ma soprattutto per la riconfigurazione dello spazio cittadino in forme innovative, destinate a influenzare in maniera decisiva anche le città minori del regno e dell’Oriente dell’isola, e successivamente anche dei comprensori centro-occidentali e settentrionali. L’aspetto più importante e programmatico nella rimodulazione del…
