Numerical Analysis of Bearing Capacity of a Ring Footing on Geogrid Reinforced Sand
2021
A ring footing is found to be of practical importance in supporting symmetrical constructions for example silos, oil storage container etc. In the present paper, numerical analysis was carried out with explicit code FLAC3D 7.0 to investigate bearing capacity of a ring footing on geogrid reinforced sand. Effects of the ratio n of its inner/outer diameter (Di/D) of a ring footing, an optimum depth to lay the geogrid layer were examined. It was found that an intersection zone was developed in soil under inner-side (aisle) of ring footing, contributing to its bearing capacity. Substantial increase of bearing capacities could be realized if ratio n of a ring footing was around 0.6. Numerical res…

Factors to correct the measured cross-sections for different treatments of photon final-state radiation (QED FSR) to: - dressed leptons, recombined with FSR photons in a cone of DeltaR < 0.1 and - bare leptons, defined after FSR. These correction factors are found to be (pseudo)-rapidity independent.
DiDuSoNet: A P2P architecture for Ditributed Dunbar-based Social Networks,
2015
Online Social Networks (OSNs) are becoming more and more popular on the Web. Distributed Online Social Networks (DOSNs) are OSNs which do not exploit a central server for storing users data and enable users to have more control on their profile content, ensuring a higher level of privacy. In a DOSN there are some technical challenges to face. One of the most important challenges is the data availability problem when a user is offline. In this paper we propose DiDuSoNet, a novel P2P Distributed Online Social Network where users can exercise full access control on their data. Our system exploits trust relationships for providing a set of important social services, such as trustness, informati…
Urbis Speculum: progetti, cantiere, protagonisti
2011
“Occhio della città”, “Teatro del Sole”, sono due delle tante definizioni che la letteratura del tempo assegnò ai Quattro Canti di Palermo, le monumentali tribune realizzate a partire dal 1608, per definire in forma monumentale la crux viarum fra le vie Toledo e Maqueda. A partire dal primo progetto, elaborato dall’ingegnere regio di Giulio Lasso, le vicende del cantiere si snodano fino alla metà degli anni venti, e oltre per quello che riguarda l’apparato scultoreo, fra lunghe soste del cantiere, ripensamenti progettuali e “rivoluzioni” iconografiche, denunciando gli inevitabili conflitti sorti fra l’autorità monarchica e il Senato cittadino nella definizione della piazza più rappresentati…
Il Palazzo Reale di Palermo in età moderna (XVI-XVII secolo)
2012
Il "Sacruma Regium Palatium" di Palermo rapppresenta nell'immaginario collettivo siciliano la testimonianza materiale più illustre dei fasti della corona d'Altavilla e in particolare dell'età ruggeriana: non a caso ancora oggi il complesso prende il nome di "Palazzo dei Normanni". Come è noto, tuttavia, il complesso ha una storia millenaria, che con lo snodarsi dei secoli ha conosciuto vicende alterne e momenti di decadimento. Questo libro è dedicato alla "rinascenza" del palazzo, cioè a quella fase del suo iter architettonico in cui, dopo due secoli di abbandono, torna a ricoprie il suo ruolo istituzionale di sede dell'autorità monarchica in Sicilia. La decisione presa da nel 1553 dal vice…
Low Level Languages for the PAPIA Machine
1986
The paper presents the low-level languages implemented up to date to program the PAPIA machine. The parallel assembly-level P-MAGRO package, the microcode level instruction set and a machine simulating environment are described.
Decentralized Lightweight Group Key Management for Dynamic Access Control in IoT Environments
2020
Rapid growth of Internet of Things (IoT) devices dealing with sensitive data has led to the emergence of new access control technologies in order to maintain this data safe from unauthorized use. In particular, a dynamic IoT environment, characterized by a high signaling overhead caused by subscribers' mobility, presents a significant concern to ensure secure data distribution to legitimate subscribers. Hence, for such dynamic environments, group key management (GKM) represents the fundamental mechanism for managing the dissemination of keys for access control and secure data distribution. However, existing access control schemes based on GKM and dedicated to IoT are mainly based on ce…
Letter Throughput and Delay Analysis of the Ideal Window
1999
We consider the problem of random access communications over a time slotted channel with feedback of infinitely multiplicity at the beginning of each collision resolution interval (CRI), i.e., users know via instantaneous feedback the number of users involved in that collision. Once this is known, the resolution algorithm (CRA) operates with binary (successful / non successful, s/ns) feedback. The analysis of this simple full feedback sensing window random access algorithm, named ideal window stabilized ALOHA, (IWSA), algorithm, provides a throughput of 0.5052 packets/slot, Its delay is also analyzed and compared with similar algorithms.
Architettura e paesaggio nella città contemporanea
2017
Negli ultimi anni il paesaggio italiano ha subìto un continuo degrado con edifici che non sempre hanno il senso di appartenenza al contesto, al paesaggio e alla storia dei luoghi. L’articolo esamina delle proposte progettuali di ambito europeo, con alcune riflessioni critiche attorno al rapporto tra paesaggio e architettura contemporanea. I progetti illustrati, seppur espressione parziale di una più ampia produzione europea e internazionale, forniscono un adeguato spunto per avviare riflessioni teoriche e progettuali sul tema del rapporto fra paesaggio e architettura contemporanea. Il percorso tra i luoghi, tra città e paesaggi, visto attraverso lo sguardo di altri, ha costituito una sorta …
An authentication case study: Antonio Palomino versus Vicente Guillo paintings in the vaulted ceiling of the Sant Joan del Mercat church (Valencia, S…
2012
In 1695, the Valencian artist Vicente Guillo was engaged in painting the vault of the Sant Joan del Mercat church in Valencia, Spain. After preliminary work was carried out, his contract was cancelled. In 1697, Antonio Palomino, renowned for the publication of his technical treatise entitled El Museo Pictorio y Escala Optica, was finally selected as the painter in charge of decorating the vaulted ceiling of Sant Joan del Mercat. This paper reports an analytical study focused on the characterisation and discrimination of the palette and painting procedures used by Palomino and Guillo in the frescoes of Sant Joan del Mercat. For this purpose, Raman spectroscopy combined with light microscopy,…
