Switching Behaviour in Smart Phone Messaging Services : It’s a Question of Context, Content, and Features of the Service
2021
This paper studies switching behaviour in smart phone messaging services. This study aims to add knowledge about the factors affecting switching behaviour in smart phone messaging services. The empirical study is qualitative, and the data was collected with interviews using the laddering method. This study was carried out to find out the reasons behind customer decisions when choosing between smart phone messaging services. Using the Push-Pull Mooring framework, the findings of this study indicate that the switching decision regarding smart phone messaging service is influenced by three factors: the context of the message, the content of the message, and the features of the service.
An Integrated Multi-service Software Simulation Platform: SIMPSONS Architecture
2005
This paper describes SIMPSONS (SIp and MPls Simulations On NS-2), which is a software platform for simulating multiple network scenarios, such as Telephony Over IP (TOIP), and multi-services networks extending the functionalities of Network Simulator NS-2. The innovative aspects of SIMPSONS is the complete integration of control protocols and traffic engineering mechanisms inside the same simulation tool. In fact, next generation networks must meet basically two fundamental requirements: support of Quality of Service (QoS) and Traffic Engineering (TE) functionalities. SIMPSONS is able to simulate DiffServ, MPLS, OSPF and SIP and their interaction in everything TOIP scenario. So with this po…
Anodic TiO2 in ReRAM: Influence of Si-doping on the Resistive Switching Properties of Titanium Oxide
2016
TiO2 has attracted much attention due to its potential widespread applications, including capacitors, photocatalysis, solar energy conversion and, more recently, redox-based random access memories (ReRAM). For micro and nano-electronics applications, TiO2 is usually grown through Chemical and Physical Vapour Deposition techniques, such as Atomic Layer Deposition (ALD), Pulsed Laser Deposition (PLD), Sputtering and so on. In ReRAM field, the control of oxide structure (crystallinity, defects concentration etc.) and the choice of electrodes are crucial to have resistive switching phenomena inside the oxide. Thus, anodizing can be proposed as a simple and low cost way to grow TiO2 and to tune …

Non linear digital control improving transient response:design and test on a multiphase VRM

Robust and Model Predictive Control applied to DC/DC converters and Shunt Active Filters
Al giorno d'oggi, la domanda di energia elettrica incrementa giorno per giorno. La gente spesso la usa con superficialità sottovalutando quanto essa sia preziosa. Fino a qualche decennio fa, la generazione di energia elettrica era centralizzata e dipendeva dallo sfruttamento delle risorse fossili. La limitatezza delle fonti fossili, insieme agli effetti ambientali del loro sfruttamento, hanno portato la ricerca a trovare vettori energetici alternativi poco inquinanti e facilmente reperibili. Lo sviluppo e la diffusione delle fonti energetiche rinnovabili hanno sancito la fine di una rete elettrica centralizzata a favore di una nuova idea di rete elettrica di tipo distribuita che permette di…
CONTROLLO DELLA CONVERSIONE DELL'ENERGIA ELETTRICA IN MICRORETI INTELLIGENTI
La limitatezza delle fonti fossili, insieme agli effetti ambientali del loro sfruttamento, hanno portato la ricerca a trovare fonti energetiche alternative poco inquinanti e facilmente reperibili. Lo sviluppo delle fonti rinnovabili e la crescente attenzione verso l’efficienza hanno permesso l'integrazione di un nuovo sistema di distribuzione dell’energia non più centralizzato, ma basato sulla generazione distribuita, permettendo all'occorrenza anche il funzionamento in autonomia di sottosistemi della rete comprendenti generazione locale e carichi, detti microgrid (µG). Una µG (fig.1) è quindi un insieme di carichi e sorgenti di energia operanti come un unico sistema [1] e che presenta innu…
Meccanismi del cambio linguistico in autori plurilingui siciliani
2014
Il contributo mette a confronto tre autori plurilingui siciliani, Andrea Camilleri, Silvana Grasso e Goliarda Sapienza, per evidenziarne, a partire da brevi esempi, le modalità del contatto linguistico grazie a diverse categorie d’analisi: interferenza, prestiti (adattati o no), calchi, commutazione di codice, enunciazione mistilingue. Si dimostra come i tre autori sfruttino tre diversi meccanismi di contaminazione: Andrea Camilleri ricorre generalmente all’enunciazione mistilingue; Silvana Grasso ha un tessuto linguistico espressionista, giocato su prestiti, neologismi e varietà di registro; infine, Goliarda Sapienza si muove unicamente all’interno del code-switching nel tentativo di dare …
Un Churel Mandir in Gujarat. Note sulla diffusione delle rappresentazioni della figura della strega in India
2021
The churels are figures of the folk imagery of a vast area of South Asia. They, commonly identified with witches, are spirits of women who died during pregnancy or childbirth, and who return to the world of the living, possessing them. The aim of this study is to provide an interpretative analysis of the representations of the churels and of the ambiguous climate that has been created around these figures in recent decades in India. A reflection on the power of the representations of the churels throughout history up to present-day India could be considered a key to penetrating the dense network of relationships and reinventions, but also of divergences and contradictions, sometimes with tr…
Fiscal Policy and Asset Price Cycles: Evidence from Four European Countries
2014
OS; International audience; We test for non-linear effects of asset prices on the fiscal policy of four major European economies (France, Italy, Spain and UK). We model government spending and revenue as time-varying transition probability Markovian processes (TVPMS), and find that: (i) in France and Italy, the impact of housing prices on government revenue is conditioned by the phase of the stock price cycle; (ii) a similar asymmetric pattern is found for the UK when considering the effect of stock price fluctuations on government revenue and spending vis-à-vis the troughs and peaks of aggregate wealth; and (iii) for Spain, a fall in government revenue is typically associated with a negati…
