Optimal Buffer Resource Allocation in Wireless Caching Networks
2019
Wireless caching systems have been exhaustively investigated in recent years. Due to limited buffer capacity, and unbalanced arrival and service rates, the backlogs may exist in the caching node and even cause buffer overflow. In this paper, we first investigate the relationship among backlogs, buffer capacity, data arrival rate and service rate, utilizing the martingale theory which is flexible in handling any arrival and service processes. Then given a target buffer overflow probability, the minimal required buffer portion is determined. If the devoted buffer capacity can fulfill all serving users' minimal buffer requirements, an optimization problem is constructed with the objective to m…
Energy Efficient Resource Allocation for Wireless Powered UAV Wireless Communication System with Short Packet
2023
The unmanned aerial vehicle (UAV), which is prominent in its flexibility and low cost, is considered to be fully utilized in the future wireless communication system to provide flexible services and improve connectivities. In this paper, we investigate the resource allocation problem in a wireless powered UAV communication system. In this considered system, The UAV acts as hybrid access point (HAP), which can first perform wireless power transfer in the downlink and charge the Internet of Thing (IoT) user devices (UDs). The UDs can use the harvested energy to deliver the data to the UAV. In the uplink, we explicitly consider short packet communication (SPC) as the transmission feature, whic…
Adapting to Dynamic LEO-B5G Systems : Meta-Critic Learning Based Efficient Resource Scheduling
2022
Low earth orbit (LEO) satellite-assisted communications have been considered as one of key elements in beyond 5G systems to provide wide coverage and cost-efficient data services. Such dynamic space-terrestrial topologies impose exponential increase in the degrees of freedom in network management. In this paper, we address two practical issues for an over-loaded LEO-terrestrial system. The first challenge is how to efficiently schedule resources to serve the massive number of connected users, such that more data and users can be delivered/served. The second challenge is how to make the algorithmic solution more resilient in adapting to dynamic wireless environments.To address them, we first…
Simultaneous harvest-and-transmit ambient backscatter communications under Rayleigh fading
2019
Ambient backscatter communications is an emerging paradigm and a key enabler for pervasive connectivity of low-powered wireless devices. It is primarily beneficial in the Internet of things (IoT) and the situations where computing and connectivity capabilities expand to sensors and miniature devices that exchange data on a low power budget. The premise of the ambient backscatter communication is to build a network of devices capable of operating in a battery-free manner by means of smart networking, radio frequency (RF) energy harvesting and power management at the granularity of individual bits and instructions. Due to this innovation in communication methods, it is essential to investigat…

L’«archivio della memoria» tra 'biografia' e ‘diario’
2018
Donatella La Monaca si inoltra nell’intrinseco rapporto tra la scrittura epistolare, saggistica ed inventiva di Tomasi di Lampedusa soffermandosi sulle modalità con cui l’invenzione e il ricordo si fondono nell’azione trasfigurante della memoria, nel suo valore cognitivo e poetico. Ci si spinge da ultimo a ricostruire i termini di un dibattito sul caso Gattopardo di cui si pongono in risalto alcuni snodi cruciali tra cui quello, che, proprio nel contesto di tale dibattito, approfondisce le fasi evolutive di un suo episodio nevralgico, ovvero la lettura, animata da tensioni etiche e civili, di Leonardo Sciascia,dall’iniziale diffidenza alla matura comprensione.Si compone così un itinerario c…
"Fabula narratur toto notissima caelo": "cornuto" e cornuti nel "Gattopardo"
2019
In Il Gattopardo of Giuseppe Tomasi di Lampedusa there are three cuckolds: Vulcan, Giuseppe Garibaldi, and Tancredi Falconeri. This study explains how this triad is constituted and shows how the three figures are related in the narrative. The analysis opens a new perspective on the interpretation of the novel and brings out some aspects of its implicit organization.

How value and trust influence loyalty in wireless telecommunications industry
2012
Despite making significant investments in enhancing the customer service experience, long-term customer loyalty remains an elusive dream for many service providers. Particularly in the telecommunications industry, switching providers even from within continuous contract relationships is easy and companies struggle to retain their customers. Trust and value are considered cornerstones of long-term relationships, so it is perhaps surprising that previous research on how relationship age and usage level actually affect value, trust and loyalty is inconclusive. The current research is set in the telecommunications services field and draws on a large-scale survey undertaken in Finland. The findi…
Indagini conoscitive per la valorizzazione dei prodotti da forno nel comprensorio del GAL Terre del Gattopardo (Sicilia)
2011
Il presente lavoro si propone di studiare il processo della panificazione in un’area ben definita della regione Sicilia, compresa tra le province di Palermo e Agrigento, al fine di individuare i possibili percorsi di valorizzazione per tutelare i prodotti da forno tradizionali. Il territorio oggetto di studio è quello dei Comuni che aderiscono al GAL (Gruppo di Azione Locale) Terre del Gattopardo i quali rappresentano un’area con una vocazione particolare per la coltura del frumento duro e per la produzione di prodotti da forno ad elevato valore tradizionale; alcuni di questi costituiscono un vero e proprio patrimonio culturale, oltre che gastronomico e alimentare, meritevoli di essere sost…
