Understanding the Key Factors of Shared Mobility Services: Palermo as a Case Study
2020
The potential success of shared mobility services in the urban area strongly depends on careful tariff planning, adequate sizing of the fleet and efficient integrated public transport system, as well as on the application of policies in favor of sustainable modes of transport. The balance between earnings and expenses is not always an easy target for the companies in those cities where these services are not well-rooted in the citizens’ mobility habits. Often only large operators in the sector can continue to offer a service generating profit. However, several factors can determine the success or the failure of shared mobility services. The objective of this study is to identify, thanks to …
EV-planning: Electric vehicle itinerary planning
2014
International audience; In the latest few years, lot of efforts have been done to pave the way to sustainable mobility, in order to solve pollution problems and fuel shortage. The use of electric vehicles (EV) is considered as one of the best ecologic and economic solution. However, autonomy barriers and limitations slow the progress and the deployment of this technology. In this paper, we propose an advanced electric vehicles' fleet management architecture. This architecture considers the most important factors that can affect the traveling mode of electric vehicles, in order to offer different services to fleet management companies for an efficient monitoring and management of their fleet…
How do airlines preferences about engines influence the competition in the commercial aircraft industry: an empirical analysis
2011
This paper examines the competitive context in the commercial aircraft industry. In particular, the aim of the research here presented is to understand what are the main drivers influencing the choice of a specific engine manufacturer in an aircraft, and how such preferences influence the competition between Airbus and Boeing. In order to do that, we have collected data about the fleet composition of the top 25 airlines and we have located the main drivers influencing the engine configuration in: route specialization, business model and maintenance policy. Implications of such empirical findings in the competition among aircraft manufacturers are finally discussed.
Simulated Annealing Technique for Fast Learning of SOM Networks
2011
The Self-Organizing Map (SOM) is a popular unsupervised neural network able to provide effective clustering and data visualization for multidimensional input datasets. In this paper, we present an application of the simulated annealing procedure to the SOM learning algorithm with the aim to obtain a fast learning and better performances in terms of quantization error. The proposed learning algorithm is called Fast Learning Self-Organized Map, and it does not affect the easiness of the basic learning algorithm of the standard SOM. The proposed learning algorithm also improves the quality of resulting maps by providing better clustering quality and topology preservation of input multi-dimensi…

Le strategie di scuse, uno studio pragmatico cross-culturale fra l’arabo libico e l’italiano
2021
La mia ricerca si colloca nell’ambito della pragmatica contrastiva, un campo di ricerca il cui obiettivo è quello di mettere a confronto due lingue differenti in relazione alle strutture e alle forme che due lingue diverse usano nel medesimo contesto d’uso; le differenze fra queste realizzazioni linguistiche sono spiegate attraverso differenze di tipo culturale. I partecipanti allo studio rappresentano due gruppi di parlanti: nativi italiani e nativi arabi. La raccolta dei dati è stata effettuata mediante la compilazione di un sondaggio scritto di tipo DCT (Discourse Completion Test). In concreto, sono state elaborate 10 situazioni comunicative atte a generare nel parlante la sollecitazione…
The effect of time-of-day and sleep deprivation on postural control: A systematic review.
2022
Background: Postural control (PC) can be affected by circadian rhythm and sleep deprivation, whereby it has been reported the result of PC measurement in clinical and experimental situations can be influenced by both factors. It has been suggested sleepiness can result in deficiency in PC, which in turn can lead to occupational accidents and subsequent injuries. This is while no study critically reviews or summarizes findings surrounding this topic in the literature. Research question: Is there any significant effect of sleep deprivation and circadian rhythm on PC variables among healthy individuals? Methods: PubMed, Web of Science, Scopus, and Embase were used to detect relevant studies. O…
Emotional intelligence in children with severe sleep-related breathing disorders
2019
Background. Obstructive sleep apnea syndrome (OSAS) affects up to 4% of a pediatric population, with many comorbidities in the medium-long term. Functional alterations in the prefrontal cortex (PFC) may explain why OSAS impacts aspects such as executive functions, memory, motor control, attention, visual-spatial skills, learning, and mood regulation. Emotional intelligence (EI) is a complex neuropsychological function that could be impaired in many clinical conditions. Purpose. The aim of the study is to evaluate the difference in emotional intelligence skills among children with OSAS and healthy subjects (nOSAS). Methods. 129 children (72 males; mean age 7.64±1.98 years) affected by OSAS w…
