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…
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…
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 …
Distributed radio map reconstruction for 5G automotive
2018
Se espera que los mapas de entorno radio sean una herramienta esencial para la optimización y gestión de recursos del 5G en vehículos. En este trabajo, consideramos el problema de la reconstrucción del mapa de entorno radio utilizando una red de sensores inalámbricos formada por nodos sensores en vehículos, nodos de acceso de una infraestructura de ciudad inteligente, etc. Debido a las limitaciones de recursos en las redes de sensores, es crucial seleccionar un pequeño número de mediciones de los sensores para reconstruir el campo. En este contexto, presentamos un novedoso algoritmo distribuido basado en el método de regresión Kriging para la reconstrucción del mapa de entorno radio en térm…

Aalto’s Principles of Urban Space and Planning in connection to William Wurster and Lewis Mumford
2015
Il saggio affronta il tema dei principi sullo spazio urbano e sul progetto urbano di Alvar Aalto, in rapporto alla influenza di Willam Wurster a Lewis Mumford. Aalto ha fatto circa 50 progetti urbanistici, molti dei quali poco conosciuti dagli studiosi. Essi variano da progetti contestuali dentro la città a progetti residenziali, centri civici, università, cimiteri, piani regionali. Sia in Finlandia, che soprattutto durante i soggiorni di Aalto in USA i contatti di Aalto e Wurster sono conosciuti, quelli con Mumford inevitabili. I progetti urbani e gli scritti di Aalto sono analizzati in relazione a quest duplice influenza. The paper focuses on Aalto's principles about urban space and plann…
Homeward : caratteri, strategie compositive, poetiche dell’abitare
2020
Il volume raccoglie dei saggi elaborati a partire da alcune lectures universitarie che, attraverso l’esposizione e il commento di alcuni edifici esemplari, testimoniano la possibile ricerca di un testo “ideale”. Una traccia di fondo tiene insieme maestri come Soane, Schinkel, Loos, Asplund, Taut, Mies van der Rohe, Le Corbusier, Kahn, e si riflette nelle loro opere: tutti hanno avuto una grande passione per l’architettura classica. Dai più lontani nel tempo sino a quelli più prossimi, c’è stata una trasmissione di questioni, di principi e insegnamenti come discendenze, lungo trame riscontrabili in filigrana. Si indaga con ampi riferimenti critici il legame delle opere con le circostanze che…
Accommodative Stimulus-Response Curve with Emoji Symbols
2017
Purpose. To evaluate the static measurement of the accommodative stimulus-response curve with emoji symbols. Methods. The accommodative stimulus-response curve was measured in 18 subjects using a Hartmann-Shack sensor to obtain the objective accommodative response from the Zernike defocus term. Measurements were acquired at different accommodative demands, from 0 to 3 D with a step of 0.5 D. Detailed and nondetailed emoji targets were used with two different sizes, corresponding to the two most common visual angles used in smartphones. Results. A regression analysis was performed to fit the mean results obtained for each target. The determination coefficient was R2≥0.988 for all targets. Fo…
