«Nolite extollere in altum cornu vestrum». Ipotesi sul campanile della chiesa della Santissima Annunziata di Messina
2022
This article addresses a series of hypothesis concerning the octagonal space indicated in Guarino Guarini’s drawings of the Church of the Santissima Annunziata in Messina in his Architettura Civile. The façade of the church was completed around 1660 by Guarino Guarini and presented a «prodigiously high» bell tower at the corner, which collapsed during the 1693 earthquake and was later rebuilt shorter. The entire church was destroyed during the 1908 earthquake. Guarini’s drawings published in his treatise suggest that there must have been an octagonal chapel with columns at the corners under the tower; perhaps it was the baptistery of the church. Alternatively, the octagon can be identified …
VESTIGIA SARACENE E NORMANNE PER ILLUSTRARE "THE NORMANS IN SICILY"
2021
In questa edizione di “Saracenic and Norman remains” si è voluta porre l’attenzione, attraverso la traduzione in lingua italiana della prefazione e della descrizione delle tavole, sulla parte meno presa in considerazione del volume, abitualmente considerato soltanto l’elegante repertorio iconografico a corredo del resoconto del viaggio in Sicilia di Henry Gally Knight, pubblicato due anni prima. Un’operazione non soltanto di “traduzione”, ma di riflessione critica sulla maturazione del pensiero storiografico di Gally Knight intorno all’architettura medievale siciliana, “saracena” e normanna in prima istanza, di cui “Saracenic and Norman remains” rappresenta un’ulteriore sviluppo in relazion…
Fully pipelined real time hardware solution for High Efficiency Video Coding (HEVC) intra prediction
2016
International audience; A fully pipelined hardware accelerator for the High Efficiency Video Coding (HEVC) intra prediction is presented in this paper in order to reduce the computation complexity coming with this module and to accelerate the concerned calculations. Two reconfigurable structures are developed in this paper, the first one concerns angular modes and is identified as Processing Element for Angular (PEA) modes, the other is made in order to handle with the Planar mode and is identified as Processing Element for the Planar (PEP) mode. Each structure is repeated in five paths, that our architecture composed of, working in parallel way. This architecture supports all intra predict…

A comparative analysis of two immersive virtual reality systems in the integration and visualization of natural hand interaction
2022
AbstractIt is generally accepted that the use of natural interaction provides a positive impact in Virtual Reality (VR) applications. Therefore, it is important to understand what is the best way to integrate and visualize this feature in VR. For this reason, this paper presents a comparative study of the integration of natural hand interaction in two immersive VR systems: a Cave Audio Visual Experience (CAVE) system –where users’ real hands are visible– and a non-see-through Head-Mounted Display (HMD) system –where only a virtual representation of the hands is possible–. In order to test the suitability of using this type of interaction in a CAVE and compare it to an HMD, we raise six rese…
Handover management in heterogenous mobile and wireless networks
2015
Since 1990, networking and mobile technologies have made a phenomenal unprecedented progress. This progress has been experienced on multiple fronts in parallel; especially on the application level and the user's needs one. This rapid evolution of the technology imposed a need for the existence of heterogeneous environments where the coverage is ensured throughout the different available networks. The challenge with such architecture would be to provide the user with the ability to navigate through the different available networks in a transparent and seamless fashion. However, the navigation among different types of networks is commonly referred to as vertical Handover. The IEEE 802.21 stan…
A fog-assisted system to defend against Sybils in vehicular crowdsourcing
2022
Technological advancements in vehicular transportation systems have led to the growth of novel paradigms, in which vehicles and infrastructures collaborate to infer high-level knowledge about phenomena of interest. Vehicular Social Network (VSN) is one such paradigm in which vehicular network entities are considered as part of an Online Social Network (OSN), paving the way for new services derived from social context. Although vehicular crowdsourcing has tremendous benefits, its deployment in real systems requires to solve important challenges including defense against Sybil attacks. This paper proposes a novel fog-assisted system that uses SybilDriver to minimize the presence of Sybil enti…
Spectrum cartography techniques, challenges, opportunities, and applications: A survey
2021
The spectrum cartography finds applications in several areas such as cognitive radios, spectrum aware communications, machine-type communications, Internet of Things, connected vehicles, wireless sensor networks, and radio frequency management systems, etc. This paper presents a survey on state-of-the-art of spectrum cartography techniques for the construction of various radio environment maps (REMs). Following a brief overview on spectrum cartography, various techniques considered to construct the REMs such as channel gain map, power spectral density map, power map, spectrum map, power propagation map, radio frequency map, and interference map are reviewed. In this paper, we compare the pe…
Multi-objective optimisations for a superscalar architecture with selective value prediction
2012
This work extends an earlier manual design space ex ploration of our developed Selective Load Value Pre diction based superscalar architecture to the L2 unified cache. A fter that we perform an automatic design space expl oration using a special developed software tool by varying several architectural parameters. Our goal is to find optim al configurations in terms of CPI (Cycles per Instruction) and energy consumption. By varying 19 architectural parameter s, as we proposed, the design space is over 2.5 millions of billions configurations which obviously means that only heuristic search can be considered. Therefore, we propose dif ferent methods of automatic design space exploratio n based…
