Testing of “Global Young's Modulus E” on a rehabilitated masonry bell tower in Venice
2017
Abstract This paper shows the effectiveness of the techniques chosen for the rehabilitation of the historic “Sant'Andrea” masonry bell-tower in Venice. The achieved rehabilitation projects based on the indenting technique consisting in removing and replacing bricks in bad conditions, and on the isolation of the bells at the belfry quote, respect all the constraints represented by the aesthetic and structural features of the building. Moreover, the experimental analyses used to define the existing state of the structure are described in detail. The tower is also an interesting case study for the validation of the proposed method to determine the global young's modulus in a rehabilitated maso…
BIM and Low-Cost Survey Techniques for Building Heritage Conservation
2017
The aim of this contribution is to illustrate a methodology for the protection and management of the building heritage, adding to the historical documentary investigations, a careful phase of survey and a conscious geometric and informational modelling of the pre-existence. The focus of this work was the Tower of Vietri sul Mare: a significant example of the architectural defense strategies adopted in Salerno in the 16th century. In fact, through the creation of digital models, it would be facilitated the management of the volumetric evolution that this tower has undergone over time, ensuring a greater accessibility and an easier understanding of the transformations it has suffered.
Finite-Difference Time-Domain Simulation of Tower and Grounding Subjected to Lightning
2015
In this paper the behavior of a tower and its grounding system, subjected to a lightning, is faced. Finite difference time domain (FDTD) method has been chosen in order to study the non-linear time domain behavior of the system. The electromagnetic problem has been described by using two type of first order time derivative equations: Maxwell's equations and Telegraph equations. Aim of this work is to evaluate the possibility of a flashover between tower and power line, by considering different cases of study.
Reliability Approach to the Design, Construction and Use of Natural Draught Cooling Towers
1989
Structures or structural elements should be designed and constructed such they are suited to their intended use. But principles for the design, construction, use and maintenace are changing evolutionary. It is due to fundamental research and the progress in technology.
The Bell-Tower Facade: An Aseismic Device in Sicily Between the 12th and 18th Centuries
2014
Imposing tower facades with belfries in the last order were built in Sicily Italy, from the Middle Ages to the late Baroque period. Until the 16th century, this model, which was inspired by northern European examples, also had a parallelepiped forepart leaning against the facade, working as containment for the pressure imparted by the inner longitudinal arches on the front, and amplified in case of earthquakes. The lacking static efficiency of these early structures is demonstrated by collapses during the strong earthquakes that hit the island in the modern age. Despite numerous cases of destruction, the memory of some prototypes survived in Sicilian constructive memory through the elaborat…
The Building of Bell-Towers Added to Romanian Churches
2016
Abstract This paper aims to emphasize a specific aspect in the evolution of the architecture of churches built by Romanian Orthodox or Greek-Catholic communities in the Sibiu region, in the second half of the eighteenth century and during the nineteenth century. More exactly, it is the widespread presence, in the ecclesiastical architecture of that county, and also in other Romanian Transylvanian settings, of the western tower, added to the church, which housed the bells and sometimes even clocks. In most cases, the raising of these towers was entrusted to Saxon masons from Sibiu, whose names have been preserved in inscriptions on the walls of edifices, or by their registering in contracts …
Beyond the “ivory tower”. Comparing academic and non-academic knowledge on social entrepreneurship
2021
The increasing relevance of societal challenges has recently brought social entrepreneurship to the fore due to its capacity to leverage entrepreneurial processes to achieve social value while ensuring profits. In this study, we apply an experimental research method to analyse the concept of social entrepreneurship comprehensively. More specifically, we develop bibliometric analysis and web crawling techniques to gather information related to social entrepreneurship from Scopus and Wikipedia. We conduct a comparative network analysis of social entrepreneurship’s conceptual structure at academic and non-academic levels. This analysis has been performed considering scientific articles’ keywor…
Dataset for the manuscript "Are remote sensing evapotranspiration models reliable 2 across South American ecoregions?" published in WRR
2021
Metadata of ‘Are remote sensing evapotranspiration models reliable across South American ecoregions?’ This document describes the file formatting and data used to run and evaluate the evapotranspiration models in this study. Because forcing data varies among models, each input file contains a different set of meteorological data placed within a folder named after the corresponding model. File format and time stamps Data files are CSV formatted with timestamps in the first column of the file. The following timestamps are used: GLEAM: Year (YYYY); Day of Year (DDD) PT-JPL: Year (YYYY); Month (MM); Day (DD) PM-MOD: Year (YYYY); Month (MM); Day (DD) PM-VI: Date (MM/DD/YYYY) Missing data Missing…
Fortfying pre-existing structures: tower houses and fortified enceintes, in Garofalo E, Scaduto F, Fortified Palaces in Early Modern Sicily. Models, …
2014
In early modern Sicily the extra-urban fortified residence was a limited but important architectural phenomenon. Starting from the last decades of XV century previous residential buildings, especially towers, were in some cases renewed by the introduction of a surrounding fortified perimeter with bastions (i.e. Donjon of Adrano; tower of Migaido). The paper presents a sequence of examples most representative of the architectural phenomenon, specially focusing on the models in use; the intertwining between residential and military needs in the conformation of inside and outside spaces; finally, the relation between image strategy and practical function.
'Bastioned’ residences: models and projects, in Garofalo E, Scaduto F, Fortified Palaces in Early Modern Sicily. Models, Image Strategy, Functions
2014
In early modern Sicily the extra-urban fortified residence was a limited but important architectural phenomenon. Starting from the last decades of the fifteenth century, previous residential buildings, especially Towers, were in some cases renewed by the introductio of a surronding fortified perimeter with bastioned (e.g. Dojon of Adrano; tower of Migaido). Subsequently the genesis of new palaces with bastions, bulwarks and pseudo- bulwarks is certainly linked to contemporary publications and specialized treaties, but local conditions played an equaly important role. The position along the Mediterranean frontier the islamic world and the presence of numerous military engineers created an en…
