Riduzione degli spostamenti indotti da scavi profondi mediante pannelli sacrificali: simulazione numerica 3D
No full text3D finite element analysis of deep excavations with cross-walls
No full textGround movements induced by deep open excavations retained by diaphragm walls may be substantially reduced using sacrificial cross-walls installed as props between the retaining walls. In this paper, a 3D finite element study is presented in which the retaining walls and the cross-walls are modelled using brick elements and accounting for the interfaces between the panels of diaphragm walls and of cross-walls. Influence of cross-walls spacing and length in reducing the horizontal deflection of diaphragm walls and the ground settlements behind the excavation is evaluated. Companion plane strain analyses, in which an homogeneous equivalent medium is considered in between the retaining walls, are also presented to assess the capability of 2D analyses to predict the performance of deep excavations in which cross-walls are used as a mitigation measure to reduce wall deflections and ground movements
On the SCTC-OCTC Method for the Analysis and Design of Circuits
No full textThis paper discusses guidelines that emphasize the
relevance of short-circuit- and open-circuit-time constant (SCTC
and OCTC, respectively) methods in the analysis and design of
electronic amplifiers. It is demonstrated that it is only necessary
to grasp a few concepts in order to understand that the two shortand
open-circuit cases fall into a single case that can be easily
addressed by low-pass and high-pass filters duality. Instead of
just teaching the methods as “recipes” for frequency-performance
systems analysis, SCTC and OCTC can be efficiently explained in
basic analog electronic courses so as to elucidate their underlying
principles. The discussion presented here will include two analysis
and design examples, used to highlight the benefits gained by
the approximated analysis technique, as well as a section that
examines the accuracy of the technique
Paola S. Salvatori - Mussolini e la storia. Dal socialismo al fascismo
No full textPaola S. Salvatori Mussolini e la storia. Dal socialismo al fascismo (1900-1922) Roma, Viella, 2016 L’uso dell’analogia storica fu uno dei principali strumenti politici ai quali il duce ricorse durante il ventennio fascista per ottenere e mantenere il consenso. Ma già nei vent’anni precedenti la conquista del potere il giovane Mussolini adoperò la storia per interpretare e rappresentare gli avvenimenti presenti: evocare la Roma antica, ragionare sulla Rivoluzione francese, ricordare particol..
