Ernesto Basile e le Esposizioni Agricole Siciliane dei primi anni del ‘900
2020
In 1891 the IV Italian National Exposition was held in Palermo, the first to have a southern city as its protagonist. The area on which the pavilions were built, obtained from the expropriation of the land belonging to the Prince of Villafranca, lent itself from the following year to accommodate the housing development and new buildings to complete the Via della Libertà, a high-bourgeois boulevard that already in 1850, by cutting the same "Firriato" of the Villafranca family, had marked the expansion towards the north of the city and seen the construction of the first buildings on its eastern front. Ernesto Basile was one of the main designers of the event and future urban creations. Althou…
A Geometrical Channel Model for MIMO Mobile-to-Mobile Fading Channels in Cooperative Networks
2009
This paper deals with the modeling and analysis of narrowband multiple-input multiple-output (MIMO) mobile- to-mobile (M2M) fading channels in relay-based cooperative networks. Non-line-of-sight (NLOS) propagation conditions are assumed in the transmission links from the source mobile station to the destination mobile station via the mobile relay. A stochastic narrowband MIMO M2M reference channel model is derived from the geometrical three-ring scattering model, where it is assumed that an infinite number of local scatterers surround the source mobile station, the mobile relay, and the destination mobile station. The complex channel gains associated with the new reference channel model are…
A Geometrical Three-Ring-Based Model for MIMO Mobile-to-Mobile Fading Channels in Cooperative Networks
2011
Published version of an article published in the journal: Eurasip Journal on Advances in Signal Processing. Also available from the publisher at: http://dx.doi.org/10.1155/2011/892871. OA This paper deals with the modeling and analysis of narrowband multiple-input multiple-output (MIMO) mobile-to-mobile (M2M) fading channels in relay-based cooperative networks. In the transmission links from the source mobile station to the destination mobile station via the mobile relay, non-line-of-sight (NLOS) propagation conditions are taken into account. A stochastic narrowband MIMO M2M reference channel model is derived from the geometrical three-ring scattering model, where it is assumed that an infi…
Bim and architectural heritage: Towards an operational methodology for the knowledge and the management of cultural heritage
2016
The study aims to answer the growing need for virtuously organize informational apparatuses related to Cultural Heritage. We propose a methodology that integrates multidisciplinary processes of interaction with information aimed at survey, documentation, management, knowledge and enhancement of historic artifacts. It is needed to review and update the procedure of instrumental data acquisition, standardization and structuring of the acquired data in a three-dimensional semantic model as well as the subsequent representability and accessibility of the model and the related database. If the use of Building Information Modeling has in recent years seen a consolidation in the procedures and the…
Family background and problems at school and in society: The role of family composition, emotional atmosphere and parental education
1997
Three studies were carried out to examine the extent to which family composition, size and atmosphere, parental control, and the level of parental education and socioeconomic status, are associated with young people’s problems at school, and later on in society. In study 1, twenty-four 13- to 14-year-old underachievers, and 24 of their matched-pair controls, and 24 overachievers and 24 of their matchedpair controls, were compared according to their family background. In study 2, sixteen low achieving pupils, 20 vocational school pupils and 21 senior high school pupils, aged between 14 and 19, were examined. In study 3, twenty unemployed young adults, 14 students with health problems, and 23…
A flexible and reconfigurable 5G networking architecture based on context and content information
2017
The need for massive content delivery is a consolidated trend in mobile communications, and will even increase for next years. Moreover, while 4G maturity and evolution is driven by video contents, next generation (5G) networks will be dominated by heterogeneous data and additional massive diffusion of Internet of Things (IoT). The current network architecture is not sufficient to cope with such traffic, which is heterogeneous in terms of latency and QoS requirements, and variable in space and time. This paper proposes architectural advances to endow the network with the necessary flexibility helping to adapt to these varying traffic needs by providing content and communication services whe…
Designing the 5G network infrastructure: a flexible and reconfigurable architecture based on context and content information
2018
5G networks will have to offer extremely high volumes of content, compared to those of today’s. Moreover, they will have to support heterogeneous traffics, including machine-to-machine, generated by a massive volume of Internet-of-Things devices. Traffic demands will be variable in time and space. In this work, we argue that all this can be achieved in a cost-effective way if the network is flexible and reconfigurable. We present the Flex5Gware network architecture, designed to meet the above requirements. Moreover, we discuss the links between flexibility and reconfigurability, on the one side, and context awareness and content awareness, on the other; we show how two of the building…
Expression of emotion through musical parameters in 3- and 5-year-olds
2019
While the use of musical parameters for emotional expression has been extensively studied, little is known about which specific musical parameters children at different ages are able to use for expressing specific emotions. We used a novel interface called Music Box that allows modification of musical parameters while music is being played in real time. Children (N = 37, 18 girls) at the age of 3 and 5 were asked to modify three parameters – tempo, loudness, and pitch – in expressing three emotions – happiness, sadness, and anger. We hypothesised that both 5-year-olds and 3-year-olds could use each of the parameters in differentiating between the emotions. Results showed that 3-year-olds we…
Learning automata based energy-efficient AI hardware design for IoT applications
2020
Energy efficiency continues to be the core design challenge for artificial intelligence (AI) hardware designers. In this paper, we propose a new AI hardware architecture targeting Internet of Things applications. The architecture is founded on the principle of learning automata, defined using propositional logic. The logic-based underpinning enables low-energy footprints as well as high learning accuracy during training and inference, which are crucial requirements for efficient AI with long operating life. We present the first insights into this new architecture in the form of a custom-designed integrated circuit for pervasive applications. Fundamental to this circuit is systematic encodin…
Timoteo Calvo Ibarra (1799-1879). Un arquitecto valenciano durante el reinado de Isabel II.
2015
In the complex scene of valencian architecture of 19th century, Timoteo Calvo Ibarra should be considered as one of the most representative authors. In his designs and interventions, such as the Literary University, the construction of new Cathedral’s Altarpiece, they are apparent the peculiarities of the first Historicism, coincident with Isabelline period. In this first stage of historicism, the homogeneity and guarantee of good taste that classicism provided was no longer valid as unique option and it will be simultaneous with romantic architecture represented by the first historicist experiences, which will conclude with the burst onto the scene of the eclecticism in the restoration of …
