Parked electric car's cabin heat management using photovoltaic powered ventilation system
2019
Abstract This paper explores the use of electric car roof mounted photovoltaic (PV) powered ventilation for cabin heat management/ventilation. A fully-functional Renault Zoe electric car has been used for performance evaluation of parked electric car ventilation directly powered by PV. This work has been part of a research project of testing electric cars in the urban environment and it has been conducted at the Edinburgh Napier University’s Transport Research Institute. In this work, parked electric car ventilation has been reported, when roof-mounted PV modules were used to operate DC powered fans for ventilation. It has been found that the DC motor-fan selection for removing the hot air …
Mechanisms of Smartphone Apps for Cigarette Smoking Cessation: Results of a Serial Mediation Model From the iCanQuit Randomized Trial
2021
Background Engagement with digital interventions is a well-known predictor of treatment outcomes, but this knowledge has had limited actionable value. Instead, learning why engagement with digital interventions impact treatment outcomes can lead to targeted improvements in their efficacy. Objective This study aimed to test a serial mediation model of an Acceptance and Commitment Therapy (ACT) smartphone intervention for smoking cessation. Methods In this randomized controlled trial, participants (N=2415) from 50 US states were assigned to the ACT-based smartphone intervention (iCanQuit) or comparison smartphone intervention (QuitGuide). Their engagement with the apps (primary measure: numb…

Acceptance of E-Learning Devices by Dental Students
2013
Background: E-Learning programs and their corresponding devices are increasingly employed to educate dental students during their clinical training. Objective: Recent progress made in the development of e-learning software as well as in hardware (computers, tablet PCs, smartphones) caused us to more closely investigate into the habits of dental students in dealing with these learning techniques. Methods: Dental students during their clinical training attended a survey compiled in cooperation with biostatisticians. The questionnaire probands were asked to complete based on previous surveys of similar subjects, allowing single as well as multiple answers. The data, which were obtained with re…
ICT applications for improving the generation and distribution efficiency of a small mediterranean island
2016
The paper presents a study on the opportunities offered by ICT for improving the efficiency of the generation and distribution system of a small island. The island taken into consideration is the Italian Lampedusa island. In the paper, the power distribution system of the island is described and the summer and winter daily load profiles are examined in order to define the more suitable control actions for improving the generation and distribution efficiency of the power system. Finally the architecture of an idoneous control system for the smart grid is proposed and an evaluation of the purchase and installation costs of components and devices for the transition of a traditional house towar…
Embedding Monitoring Systems for Cured-In-Place Pipes
2017
This paper proposes a non-intrusive electrical measurement system for monitoring some relevant parameters in pipeline systems. Temperature and flow-rate are monitored, using MEMS sensors. The flow-rate is evaluated by measuring pipe vibration, with a 3 axis accelerometer, induced by turbulence when fluid flows within the tube. The sensors are embedded, during the curing process of the cured-in-place pipes, in the pipes wall making the system suitable to be installed in renewed or new pipeline. The first experimental results show that it may be possible to obtain, at low-cost, a fully monitored distribution network.
Smart cities: Case studies
2016
Il capitolo mostra alcuni esempi di smart cities. Nel capitolo i casi di studio sono divisi in aree geografiche, che a livello macroscopico si riferiscono a diversi tipi di città e comunità in relazione a diversi livelli di innovazione tecnologica e tipo di capitale umano, che sono fattori chiave per raggiungere uno sviluppo smart. Le città di nuova costruzione sono città appartenenti all'area asiatica pianificate da zero per limitare emissioni nocive ed alzare la qualità della vita dei cittadini. Nel paragrafo sulle città del Nord Europa e quelle del Mediterraneo sono descritte città che possiedono alte caratteristiche storiche. Talvolta queste hanno poche possibilità - per le loro caratte…
A space-division time-division multiple access scheme for high throughput provisioning in WLANs
2005
Directional antennas may dramatically increase the capacity of a Wireless LAN by allowing several stations to simultaneously communicate. Since deployment of directive/smart antennas on the customer's terminals is awkward (for technological, cost, robustness, and convenience reasons) it is of interest to deploy advanced antenna solutions only at the Access Point. When omnidirectional transmissions are used at the Mobile Stations, the asynchronous nature of the 802.11 MAC handshake structurally limits the possibility to exploit spatial reuse. Significant throughput enhancements can be achieved only at the expense of redesigning (part of) the 802.11 MAC protocol: mainly a form of synchronizat…
Reshaping the Urban Environment Through Mobility Projects and Practices: Lessons from the Case of Palermo
2016
Transport and mobility are crucial factors in the process of adaptation of contemporary urban areas to the challenge of sustainable development. In this perspective, however, cities need to perform a more effective integration between a wide range of different policies and planning practices. Together with a more effective integration between transport policy and land-use planning, for instance, cities could take growing advantage by organisational factors, as well as the spreading of new technologies and the related processes of social innovation. Through the description of several project and planning initiatives taking place in Palermo, the fifth Italian city, this paper attempts to expl…
Survey of Formal Verification Methods for Smart Contracts on Blockchain
2019
Due to the immutable nature of distributed ledger technology such as blockchain, it is of utter importance that a smart contract works as intended before employment outside test network. This is since any bugs or errors will become permanent once published to the live network, and could lead to substantial economic losses; as manifested in the infamous DAO smart contract exploit hack in 2016. In order to avoid this, formal verification methods can be used to ensure that the contract behaves according to given specifications. This paper presents a survey of the state of the art of formal verification of smart contracts. Being a relatively new research area, a standard or best practice for fo…
