Geovisualizing the sail-to-steam transition through vessel movement data
2017
International audience; Technological transitions in the maritime and port industries go along with increased transport and economic efficiency, resulting in faster movements and longer travelled distances. Yet, such transformations may also enhance disparities between winners and loosers, should they be ports or shipping companies. This research focuses on the particular case of the transition from sail to steam over the period 1890-1925, which witnesses the rapid replacement of sailing vessels, the latter concentrating 65% of the world fleet in 1890 but only 3.5% in 1925. It applies a variety of measures to compare how these two layers overlap in the network (at links and ports) and what …
The Port and its Environment
2013
In times of increasing environmental awareness, the port-city relationship has gained a new meaning since ports have been seen as the origin of both negative and positive externalities affecting the public wellbeing. While the former are the result of port expansion, the latter are the result of transforming obsolete port areas into recreational facilities. Therefore, in order to support effective policy-making, in this research is emphasized the need of measuring these environmental externalities. Considering their non-market nature, the contingent valuation method is introduced as an economic tool capable of overcoming this obstacle. Thus, the cases of two ports in Spain, namely Valencia …
Lo sviluppo sostenibile della pesca nella marineria di Mazara del Vallo
2011
In a place like Sicily, where sea fishing and port activities are part of the territory, history and culture, fishery has always been vital to man and, for this reason, today it must be studied, protected and helped in the difficult transition towards long-term sustainability. Fishing is a driving sector for Mazara economy both for number of working days during the fishing season, and for industrial activities operating around this field (transformation, packaging, and distribution). A micro-economic analysis was carried on a sample of fishing enterprises in order to analyze the problems of the here studied seamanship. The analysis is based on the employers’ interviews. The collected data h…
Scope of Negative Integration: A Comparative Analysis of Post, Public Transport and Port Services
2014
There is extensive literature that explains how liberalization policy deepens and widens. In the literature of European integration such reform is commonly considered to be the result of a bias towards liberalization in the treaties, thereby giving the European Commission and the European Court of Justice wide-ranging leverage to enforce such reform. However, such approaches have been criticized for being de-politicized – for failing to understand the conflicts inherent in controversial policies. It is therefore of interest to explore the scope conditions of this constitutional bias assumption in areas where liberalization policy is disputed. This article analyzes the EU decision-making pro…
Developing business networking opportunities for SMEs through business ecosystem and ICT
2010
Globalisation is a new challenge for European small and medium enterprises; indeed, on one hand, it represents a threat, since new emerging companies are entering their domestic market, but on the other hand, it represents the opportunity to enter new emerging and growing markets. In order to win this challenge, European SMEs need to play the networking card; in fact, it is well acknowledged that networking can improve SMEs effectiveness and efficiency which is absolutely necessary to win the globalisation battle. Many public regional institutions are thinking about how to improve the networking capacity of their SMEs through specific programs and investments. This paper reports the results…
Compression Methods for Microclimate Data Based on Linear Approximation of Sensor Data
2019
Edge computing is currently one of the main research topics in the field of Internet of Things. Edge computing requires lightweight and computationally simple algorithms for sensor data analytics. Sensing edge devices are often battery powered and have a wireless connection. In designing edge devices the energy efficiency needs to be taken into account. Pre-processing the data locally in the edge device reduces the amount of data and thus decreases the energy consumption of wireless data transmission. Sensor data compression algorithms presented in this paper are mainly based on data linearity. Microclimate data is near linear in short time window and thus simple linear approximation based …
Unaccompanied foreign minors in the Italian context: From legal order to networking in educational services
2016
As the result of armed conflict, poverty or natural disasters, many children move away from their families and culture of origin. In 2014, in Italy, the number of unaccompanied foreign minors was approximately 11,000. They represent the most vulnerable of the migration phenomenon and for this reason, in December 2013, the Directorate General of Immigration and Integration Policy of the Ministry of Labour and Social Policy, adopted new guidelines for policies on reception, repatriation and effective integration arrangements of unaccompanied foreign minors. It is possible to promote the implementation of the opportunities aimed at the children concerned activating a networking that involve Na…
Industry 4.0: Advanced digital solutions implemented on a close power loop test bench
2021
Abstract The paradigm of Industry 4.0 allows to increase the efficiency and effectiveness of the production. Companies that will implement advanced solutions in production systems will increase their level of competitiveness and will be able reach high market shares. The present paper is focused on the development of advanced digital solutions to be implemented on a close power loop test bench designed to test high power transmissions for naval unit. In particular, the test configuration consists of a back-to-back connection between two identical mechanical reducers. Since the efficiency of these systems are very high, it is not necessary to use large electric motors, thus managing to conta…
Optical Plasmonic Yagi-Uda Nano-Antennas Array for Energy Harvesting Applications
2020
Optical nanoantennas have been of great interest recently due to their ability to support a highly efficient, localized surface plasmon resonance and produce significantly enhanced and highly confined electromagnetic fields. The Yagi-Uda nanoantenna, an optical analogue of the well-established radiofrequency Yagi-Uda antenna, stands out by its efficient unidirectional light emission and enhancement. In this paper, the design of an optical plasmonic Yagi-Uda nanoantenna for energy harvesting application is proposed. The enhancement of the directivity is reached by means of an organization in array. The simulation results, carried out by 3D code CST Studio, show that the proposed nanoantenna …
SEAI: Social Emotional Artificial Intelligence Based on Damasio’s Theory of Mind
2018
A socially intelligent robot must be capable to extract meaningful information in real-time from the social environment and react accordingly with coherent human-like behaviour. Moreover, it should be able to internalise this information, to reason on it at a higher abstract level, build its own opinions independently and then automatically bias the decision-making according to its unique experience. In the last decades, neuroscience research highlighted the link between the evolution of such complex behaviour and the evolution of a certain level of consciousness, which cannot leave out of a body that feels emotions as discriminants and prompters. In order to develop cognitive systems for s…
