La Grotta dei Moscerini in località Don Simone (Canino, VT): prima campagna di scavo
No full textThe Moscerini cave is located in northern Latium along the Fiora river, in an area known as Don Simone locality. The site has been identified during an archaeological survey carried out in 2019. The preliminary results of the first stratigraphic investigation conducted at the entrance of the cave in 2021 are presented in the paper. The upper part of the deposit can be dated back to the modern period, thanks to scarce material culture recovered. A hearth has been uncovered at the top of a concentration of material culture: impasto pottery sherds, pebbles – some of them showing use traces –, fragments of speleothems and some knapped flint tool. At the entrance of the cave the area around the fire place has been organized as walking surface (presence of fine sediments and small artifacts) and the deposit below as drainage arrangement (stones, speleothems fragments, pebbles). The material culture found fits into the repertoire of the Early Rinaldone facies, referring to the Early Copper Age (3700-3300 BC). The deposit, still under excavation, appears different from the typical Rinaldone assemblage of grave goods and more similar to a household (or ritual?) context

Recurrence time distribution and temporal clustering properties of a cellular automaton modelling landslide events
No full textReasonable prediction of landslide occurrences in a given area requires the choice of an appropriate probability distribution of recurrence time intervals. Although landslides are widespread and frequent in many parts of the world, complete databases of landslide occurrences over large periods are missing and often such natural disasters are treated as processes uncorrelated in time and, therefore, Poisson distributed. In this paper, we examine the recurrence time statistics of landslide events simulated by a cellular automaton model that reproduces well the actual frequency-size statistics of landslide catalogues. The complex time series are analysed by varying both the threshold above which the time between events is recorded and the values of the key model parameters. The synthetic recurrence time probability distribution is shown to be strongly dependent on the rate at which instability is approached, providing a smooth crossover from a power-law regime to a Weibull regime. Moreover, a Fano factor analysis shows a clear indication of different degrees of correlation in landslide time series. Such a finding supports, at least in part, a recent analysis performed for the first time of an historical landslide time series over a time window of fifty years. © 2013 Author(s)
Proporzioni e geometria del corpo umano nel disegno manuale prodromici alla rappresentazione digitale
No full textBody drawing has always been a current topic. In the past it was mainly linked to the figurative arts, nowadays it refers to all project fields in architecture, product design and fashion. Due to its transversal character, the body drawing has been the subject of both analog and digital representations. If the ways in which it was represented have adapted over time to technical and digital innovations, the geometric and proportional principles underlying the drawing of the human figure have remained almost unchanged. Precisely the permanence still today in the body digital modeling of the proportional relationships encoded starting from the Renaissance constitutes the interest from which this research begins.
If in the Renaissance the principles for the representation of architectural spaces in artistic works were well known, the principles for the construction of the image of the human figures present in them were less debated by treatises. The paper analyzes in the context of the treatises of the time the section of the volume by Abraham Bosse in which the author introduces a method for drawing and also for the relief of the human body, synthesizing it with a knot scheme defined by the same author as “wire figure”.
This scheme becomes the starting point to build graphically and with freehand drawing techniques the representation of anatomical shapes and therefore of the drapery of the dress worn. The graphic analysis compares the dimensions between the anatomical parts in the time and current measurement systems.Il disegno del corpo è un tema da sempre attuale. In passato era legato prevalentemente alle arti figurative, oggigiorno è riferito a tutti gli ambiti del progetto, in architettura, nel design del prodotto e nella moda. Proprio per la sua trasversalità il disegno del corpo è stato oggetto di rappresentazioni sia analogiche che digitali. Se le modalità con le quali è stato rappresentato si sono adeguate nel tempo alle innovazioni tecniche e digitali, i principi geometrici e proporzionali alla base del disegno della figura umana sono rimasti pressoché invariati. Proprio la permanenza fino ad oggi nella modellazione digitale del corpo umano dei rapporti proporzionali codificati a partire dal Rinascimento, costituisce l’interesse da cui principia la presente ricerca.
Se nel Rinascimento erano ben noti i principi per la rappresentazione degli spazi architettonici nelle opere artistiche, meno affrontati dalla trattatistica erano i principi per la costruzione dell’immagine delle figure umane in esse presenti. Il contributo analizza nell’ambito della trattatistica dell’epoca la sezione del volume di Abraham Bosse in cui l’autore introduce un metodo per il disegno e anche per il rilievo del corpo umano, sintetizzandolo con uno schema a nodi definito dallo stesso autore “a filo di ferro”.
Tale schema diventa il punto di partenza per costruire graficamente e con l’ausilio delle tecniche del disegno a mano libera la rappresentazione delle forme anatomiche e quindi del panneggio dell’abito indossato. L’analisi grafica a supporto della trattazione pone a confronto le dimensioni tra le parti anatomiche nei sistemi di misura del tempo ed attuali
Fermi surface evolution of the 2D Hubbard model within a novel four-pole approximation
No full textWe present a novel solution of the 2D Hubbard model in the framework of the Composite Operator Method within a four-pole approximation. We adopt a basis of four fields: the two Hubbard operators plus two fields describing the Hubbard transitions dressed by nearest-neighbor spin fluctuations. We include these nonlocal operators because spin fluctuations play a dominant role in strongly correlated electronic systems with respect to other types of nonlocal charge, pair and double-occupancy fluctuations. The approximate solution performs very well once compared with advanced (semi-) numerical methods from the weak-to the strong-coupling regime, being by far less computational-resource demanding. We adopt this solution to study the single-particle properties of the model in the strong coupling regime, where the effects of strong short-range magnetic correlations are more relevant and could be responsible for anomalous features. In particular, we will focus on the characterization of the Fermi surface and of its evolution with doping. (c) 2018 Author(s).

No full textIl disegno della città nelle tavole del De Nola. Analisi geometrico-dimensionale delle iconografie
No full textThis paper introduces the analysis of the ancient city of Nola through the comparative study of two Tables among the four attached to De Nola Treatise (1514) by Ambrogio Leone, also in comparison with the contemporary city. These drawings are an important graphic-documentary testimony of the finds of the ancient city in the Renaissance period as well as the theoretical-geometric knowledge of the author discussed in this essay. Starting from the graphic analysis of Table II entitled Nola Vetus, this research studies its geometric-dimensional aspects, based on the Science of Drawing, not only for a critical reinterpretation of Tables attached to Treatise but also to connect the ancient city to the traces still today present in the contemporary territory.
This essay consolidates the multifaceted character of the author as a draftsman, topographer and typographer as well as a humanist scholar, together with the essays by Argenziano and Pisacane in this Proceedings book and in continuity with the research already presented at the UID 2020 Conference
Geometry and Urban Shape of the City of Nola through the Drawings of the De Nola by A. Leone (1514)
No full textThis paper focuses on the geometric and graphic analysis of Table III
among the four attached to the De Nola Treatise by Ambrogio Leone (1514), in
which the author studied the relationship between the shape of the ancient city
with the Renaissance one through geometric simplifications as polygonal regular
surfaces (square, hexagon and dodecagon) and circular one. These assessments
have been extensively described in Chapter II of the Treatise. Our analysis
consisted in re-reading the text in which the author describes Table III, in the
vectoral re-drawing of the table itself and in the algebraic and dimensional
evaluations according to the original measurement units. The results achieved
allowed a further verification with the shape of the contemporary city in GIS
project, estimating the accuracy of the survey of the urban perimeter carried out
by Leone, of its drawing in Table III, and of its geometric and algebraic
analyzes
