On the thermo-mechanical behaviour of DEMO water-cooled lithium lead equatorial outboard blanket module

2017

Abstract Within the framework of EUROfusion R&D activities an intense research campaign has been carried out at the University of Palermo, in close cooperation with ENEA Brasimone, in order to investigate the thermo-mechanical performances of the DEMO water-cooled lithium lead breeding blanket (WCLL). In particular, attention has been paid to the most recent geometric configuration of the DEMO WCLL outboard equatorial module, as designed by WCLL project team during 2015, endowed with an attachment system based on the use of radial pins, purposely outlined to connect the module back-plate to its back-supporting structure, that have been properly considered to simulate more realistically the …

Genesi geometrica delle volte centriche

1996

Un'analisi completa degli organismi voltati comporta lo studio delle molteplici componenti necessarie alla loro definizione: configurazione geometrica, sistema costruttivo, area storico-geografica di appartenenza, interpretazioni Stilistiche. L’obiettivo di questo studio è indirizzato all' analisi delle volte continue su pianta centrica definibili attraverso le leggi della geometria euclidea. L’indagine si pone all'interno dei confini relativi alla loro configurazione geometrica e il criterio adottato, svincolato da classificazioni di carattere tipologico o stilistico, propone l'identificazione di famiglie geometriche in base alla figura del poligono di base dell'impianto. Si può identifica…

A comprehensive analysis of vaulted bodies involves the study of the multiple components necessary for their definition: geometric configuration construction system historical-geographical area of belonging interpretations Stylistic. The objective of this study is directed to the 'analysis of continuous vaults on a centric plan definable through the laws of Euclidean geometry. The investigation arises within the boundaries related to their geometric configuration and the criterion adopted freed from typological or stylistic classifications proposes the identification of geometric families based on the figure of the basic polygon of the plant. An ordering process can be identified to explain the compositional process of curved-roofed central plants: that is the elaboration of a series of theoretical models developed according to an abacus referring to the basic geometries of the triangle square and pentagon is possible. It is not intended to impose a classification but to propose a study tool that thanks to a few simple compositional rules develops a very large number of configurationthe question remains as to why only a part has been used for the realization of vaulted covered centric buildings but this presumes considerations of a historical formal and constructive nature extraneous to this discussion.Settore ICAR/17 - Disegno

Construction stages of cable-stayed bridges with composite deck

2012

A cable-stayed bridge is built by following a construction sequence of different subsequent stages that imply changes of the geometric configuration, restraints and consequently stress and strain patterns. A study is presented about stay stressing sequences in cable-stayed bridges with composite deck for the case of construction made by the cantilever method. Initial cable forces are found through partial elastic schemes of construction stages. Different stay stressing procedures are implemented and a comparison between them is proposed in order to evaluate the differences in terms of deformed shape and internal force distribution of the deck and the pylon. Results can be useful to give pra…

Three-Dimensional Classification of Lower Third Molars and Their Relationship to the Mandibular Canal.

2021

PURPOSE To develop a novel classification making full use of radiographic three-dimensional (3D) information to describe the position, geometric configuration of a mandibular third molar (M3M) and its spatial relation to neighboring structures such as the mandibular canal (MC). The classification presented in this study helps to establish a common language and serves as a framework for further studies, for example, on 3D parameters influencing prognosis of the M3M and level of difficulty associated with its removal. MATERIAL AND METHODS A total of 8 parameters were included in the classification including position, the cranio-caudal height, the number of roots of the M3M as well as its spat…
