Efficient Power Allocation for Multi-Cell Uplink NOMA Network
2019
Digital technologies are rapidly shaping the modern concepts of urbanization. It is a key element of developing practical smart cities of the future. In fact, they are the catalyst for the increasing networking of all areas of life in a smart city. Recent development in the domain of communication technologies has opened new avenues to realize the concept of smart cities. One of such communication technology is non-orthogonal multiple access (NOMA) for future cellular communications. This article, therefore, focuses on the interference management of uplink cellular NOMA systems. Specifically, we propose a power optimization technique for NOMA to improve the sum-rate in a multi-cell environm…
Energy Communities in urban areas: Comparison of energy strategy and economic feasibility in Italy and Spain
2023
Energy communities using renewable energy sources directly contributes to reduction of climate-change gas emissions and energy consumption in the European Union. In addition, energy communities enable citizens to transform from (passive) consumers to prosumers (active consumers and producers) and to play a proactive role in the deployment of energy transition in urban areas. As the transposition of European rules about energy communities into the national laws of EU Member States is very articulated and differentiated, this study proposes a framework to analyze and compare regulatory and financial instruments. This framework is applied to the analysis of the case of Italy and Spain, as repr…
Transmission Optimization and Resource Allocation for Wireless Powered Dense Vehicle Area Network With Energy Recycling
2022
The wireless-powered communication paradigm brings self-sustainability to the on-vehicle sensors by harvesting the energy from radiated radio frequency (RF) signals. This paper proposes a novel transmission and resource allocation strategy for the scenario where multiple wireless powered vehicle area networks (VAN) co-existed with high density. The considered multi-VAN system consists of a remote master access point (MAP), multiple on-vehicle hybrid access points (HAPs) and sensors. Unlike previous works, we consider that the sensors can recycle the radiated radio frequency energy from all the HAPs when HAPs communicate with MAP, so the dedicated signals for energy harvesting (EH) are unnec…
Enregistrer les interactions au restaurant : atouts et contraintes d’un cadre expérimental
2013
Dans le cadre d’un travail de recherche en Analyse Conversationnelle (Sacks, 1992) traitant des dimensions linguistiques et multimodales des interactions entre le personnel de service et les clients lors d’un repas au restaurant, nous avons élaboré une partie de notre corpus dans un restaurant expérimental équipé d’un système d’enregistrement audio et vidéo. Dans cet article, nous exposerons comment ce dispositif a été utilisé pour la constitution de notre corpus afin de capter des données authentiques enregistrées dans leur contexte naturel de production.Grâce à l’analyse fine de deux extraits, nous montrerons que le dispositif technique à disposition dans cette structure ne peut pas être …
Conflicto, materialidad y enseñanza del inglés en Nazaret
2021
El capítulo narra la experiencia del proyecto "Words Matter/Palabras reales" en un colegio público del barrio desfavorecido de Nazaret, en la ciudad de Valencia, y lo contextualiza en la filosofía de los Nuevos materialismos, en los Nuevos estudios sobre literacidad, en el imperialismo lingüístico del inglés, y la teoría relacional del arte. HAR2017-85230-R The chapter describes the experience of the project "Words Matter / Palabras reales" as developed in a public school in the underprivileged neighborhood of Nazaret, in the city of Valencia (Spain). The description of the project is contextualized in New materialisms, New Literacy Studies, English linguistic imperialism, and the relationa…
Consumers’ Willingness to Pay for Agri-Food Products Delivered with Electric Vehicles in the Short Supply Chains
2022
This study aims at investigating the consumers’ willingness to pay (WTP) for agri-food products delivered in the farmers markets with electric vehicles (EVs). The empirical analysis has been carried out by administering an online questionnaire to 273 consumers within a hypothetical context. A multiple price list has been provided in order to measure the price premium for 1 kg of oranges transported by EVs comparing with the ones transported by traditional vehicles. A Tobit regression model has been used for the data analysis in order to identify the most influential factors affecting the consumers’ WTP. Results suggest that consumers’ WTP is mainly influenced by environmental attitudes, kn…

Multimodal Communication and Peer Interaction during Equation-Solving Sessions with and without Tangible Technologies
2023
Despite the increasing use of technologies in the classroom, there are concerns that technology-enhanced learning environments may hinder students’ communication and interaction. In this study, we investigated how tangible technologies can enhance students’ multimodal communication and interaction during equation-solving pair work compared to working without such technologies. A tangible app for learning equation solving was developed and tested in fourth and fifth-grade classrooms with two class teachers and 24 students. Video data of the interventions were analysed using deductive and inductive content analysis. Coded data were also quantified for quantitative analysis. Additionally, teac…
Rendita catastale e “rendita solare” degli impianti di produzione elettrica a fonti rinnovabili: perequazione fiscale energetico-immobiliare
2014
Fra i temi affrontati dalla legge 11 marzo 2011, n. 23, recante delega al governo per un sistema fiscale più equo, spiccano le questioni fondamentali della riforma catastale e della fiscalità energetico-ambientale, di cui si tratta nel presente studio. La nuova riforma del catasto dei fabbricati aspira a realizzare un sistema fiscale più perequato at-traverso la rimozione della disparità fra redditi (e valori) catastali e redditi (e valori) osservabili nei mercati immobiliari. Il tema catastale è rilevante per i molteplici effetti fiscali che ne derivano, e il divario esistente fra i valori di mercato e quelli catastali, hanno suscitato un grande interesse degli studiosi di estimo, stimolan…
Erraticism and multicultural permeability of urban fabric in Palermo
2017
Interactions between physical and social space draw different urban dimensions, or cultural landscape mosaics, which constantly change and evolve. The shape of the city promotes or discourages multiculturalism and social relations. The latter, in turn, reverberate in the way in which urban space is used, not only to meet basic needs - dictated by reason of survival (housing, employment, and services for education, care, leisure, etc.), but also because the inhabitants are driven by the desire for happiness and the simultaneous meeting that Lefebvre described as the “individualization in socialization”. Migrants groups have historically inhabited the central areas of cities, initially approp…
