Assessing the Open Trenches in Screening Railway Ground-Borne Vibrations by Means of Artificial Neural Network
2009
Reducing ground borne vibrations in urban areas is a very challenging task in railway transportation. Many mitigation measures can be considered and applied; among these open trenches are very effective. This paper deals with the study of the effect, in terms of reduction of vertical and horizontal displacements and velocities, of the open trenches. 2D FEM simulations have been performed and several open trench configurations have been analysed varying the main geometric features such as width and depth, distance from the rail, thickness of the soil layer over the rigid bedrock, type of the ground, ratio between the depth of the trench, and the thickness of the soil layer. For quantifying t…

Bel-Air, Sénas (Bouches-du-Rhône) : a Late Neolithic open-air settlement site on the eastern foot-slopes of the Massif des Alpilles. Preliminary resu…
2014
This article is the first presentation of the excavation results following the developer-led archaeological project carried out between July and August 2012 at the site of Bel-Air, Sénas, Bouches-du-Rhône. Our current understanding of the diverse archaeological remains show that a densely occupied settlement existed within a relatively short-lived period during the second phase of the Late Neolithic in Provence, between 2880 and 2490 BC. The occupation is characterised by several phases of activity, which are at this stage of research, difficult to refine, but all of them being associated with the Couronnien group.
A reinvented archetype. The open-air theater on the edge of the city
2020
In southern Italy and in Sicily, over the past forty years, a series of urban redevelopment projects have been carried out, involving the construction of small theaters facing the Mediterranean landscape. !ey are re-invention projects of the archetype of the Greek theater that establish with the external landscape the same “sense of contemplation” expressed by the theaters of antiquity. Despite their privileged position, these theaters are occasionally used in the summer periods for tourist entertainment shows. Shows substantially distant from those of the past, as they lack an “educational” idea aimed at the construction of processes of self-recognition and identification.

Computation of flow velocity in gravel bed channels
2002
Accurate estimate of flow-velocity profile is of crucial importance both for scientific purposes and for solving numerous engineering problems that include, among others, sediment transport, contaminant transport, flow resistance evaluation. This paper presents a new empirical equation to represent the vertical velocity profile. The proposed equation is essentially a modified form of the well-known logarithm law of the wall and contains three parameters having a clear physical meaning. The applicability of the equation and its accuracy assessment for different hydraulic conditions, including non-uniform conditions, is verified by using experimental data obtained by different sources. The va…
