Sustainable Transportation Management System for a Fleet of Electric Vehicles
2015
In the last few years, significant efforts have been devoted to developing intelligent and sustainable transportation to address pollution problems and fuel shortages. Transportation agencies in various countries, along with several standardization organizations, have proposed different types of energy sources (such as hydrogen, biodiesel, electric, and hybrid technologies) as alternatives to fossil fuel to achieve a more ecofriendly and sustainable environment. However, to achieve this goal, there are significant challenges that still need to be addressed. We present a survey on sustainable transportation systems that aim to reduce pollution and greenhouse gas emissions. We describe the ar…
Eletric vehicles impact using renewable energy
2015
In this moment, the principle topics for the modern world are the reduction of environmental pollution and the production of energy from renewable sources (for example photovoltaic system, wind farm, hydroelectric plants, etc.). This particular attention is determined by different reasons, in particular from the Kyoto Protocol, and from different problems as greenhouse effect, acid rain and climate change. The scope of this work is to study, for different years (1997-2013) in Italy, the production of electric energy from renewable and non-renewable. At a later stage, the attention will be on the consumption of the electric energy divided for different sectors. In particular, we study the po…
Le flotte degli Austrias e gli scali italiani: una messa a punto
2019
Since the sixteenth century, the threat of Ottoman armies and Barbary corsairs forced Spain to gradually equip and upgrade a fleet of galleys - organized in teams - which in the "Italian" geopolitical space was headed by the domains that had a maritime projection (Kingdoms of Naples, Sicily, Sardinia) and the "connected" port of Genoa. Furthermore, new territories (the State of the Presidi, the feudal enclave of Finale) were acquired to facilitate navigation within the western Mediterranean borders and the use of Ligurian ports was negotiated with the Republic of Genoa. The maritime war in its various forms was therefore at the base of an elaborate logistic and strategic organization, which…
Bioflocculation of Euglena gracilis via direct application of fungal filaments: a rapid harvesting method
2021
Funding Information: Special thanks to the US Agricultural Research Service for the provision of fungal strains. Thanks also to Dr Marilyn Wiebe (Technical Research Centre of Finland) for her expert advice on fungi and Johanna Oja for her technical help. This research was enabled by funding from The Land and Water Technology Foundation, The Finnish Cultural Foundation, and The Finnish Foundation for Technology Promotion. Publisher Copyright: © 2021, The Author(s). The high cost and environmental impact of traditional microalgal harvesting methods limit commercialization of microalgal biomass. Fungal bioflocculation of microalgae is a promising low-cost, eco-friendly method but the range of …
Print and online newspapers as material artefacts
2014
Traditional newspaper journalism is in a state of crisis and there have been several attempts to overcome this. Many discourses have reiterated the triumphal march of a digital revolution in newspaper journalism and anticipated the end of the print newspaper. This moment calls for an in-depth analysis of reader habits of news consumption and use in order to understand the audiences for journalistic output and their relationship with the journalistic objects. In this study, we adopt a multi-method approach, integrating (1) qualitative content analysis of student essays dealing with the physicality of printed and online newspapers, (2) ethnographic observation of the use practices of readers…
SHIPPING 4.0: GENERAL FRAMEWORK FOR A NEW CYBERSHIPPING ERA
2019
The fourth industrial revolution, also referred to as Industry 4.0, is a disruptive transformation process aimed which, by means of digital technologies, is substantially innovating the value creation processes in all industry contexts. With such premise, industry 4.0 is in particular expected to have a substantial impact on the maritime transport and shipping sectors, where smart ships and autonomous vessels are expected to be the building blocks of a new interconnected maritime ecosystem. The application of Industry 4.0 principles to the shipping domain (Shipping 4.0) has thus raised a scientific debate about the efficiency, sustainability, and safety of maritime transport. Recent researc…
Innowacyjne rozwiązania w logistyce transportu
2016
The article discusses the main issues of innovative solutions for transportation, which affect the maximization of companies’ profits. The article pointed out the multitude of technological advances that due to its scope will cover all modes of transport. The author tried to show the most interesting, sometimes even futuristic solutions, which today’s realization is impossible, but in the near future they might contribute to revolutionization of the transportation market.
Is VIRTU4L larger than VIR7UAL? Automatic processing of number quantity and lexical representations in leet words.
2015
Recent research has shown that leet words (i.e., words in which some of the letters are replaced by visually similar digits; e.g., VIRTU4L) can be processed as their base words without much cost. However, it remains unclear whether the digits inserted in leet words are simply processed as letters or whether they are simultaneously processed as numbers (i.e., in terms of access to their quantity representation). To address this question, we conducted two experiments that examined the size congruity effect (i.e., when comparisons of the physical size of numbers are affected by their numerical magnitudes) in a physical-size judgment task. Participants were presented with pairs of leet words th…
The Heterogeneous Fleet Vehicle Routing Problem with Draft Limits
2023
Over the past two decades, international maritime transport has been characterized by the advent of ever larger ships. This phenomenon is known as naval gigantism. If, on the one hand, naval gigantism allows to reduce transport costs by exploiting the economies of scale achievable by large ships, on the other hand, it implies a series of operational issues. Indeed, due to their large draft, such giant vessels are not allowed to enter small ports when fully or near-fully loaded, and in some cases, they cannot enter such small ports at all. In fact, their draft can strongly vary depending on the load on board. This implies restrictions for vessels in accessing ports, which impact not only at …
