An optimization approach for efficient management of EV parking lots with batteries recharging facilities
2013
In this paper an optimization approach to devise efficient management strategies for Electric Vehicles parking lots is proposed. A Monte Carlo approach is used to evaluate the load consumption profile for groups of Electric Vehicles showing different features. The Monte Carlo approach allows to combine the different social and economical features affecting the commercial penetration of Electric Vehicles with the technical aspects. The basic feature to be assessed is the initial State Of Charge, which in turn depends on the distance travelled by the vehicle since the last recharge and thus by the usage of the vehicle (private, professional). The model is then used to optimize some objective …
Precision Oliviculture: Research Topics, Challenges, and Opportunities—A Review
2022
Since the beginning of the 21st century, there has been an increase in the agricultural area devoted to olive growing and in the consumption of extra virgin olive oil (EVOO). The continuous change in cultivation techniques implemented poses new challenges to ensure environmental and economic sustainability. In this context, precision oliviculture (PO) is having an increasing scientific interest and impact on the sector. Its implementation depends on various technological developments: sensors for local and remote crop monitoring, global navigation satellite system (GNSS), equipment and machinery to perform site-specific management through variable rate application (VRA), implementation of g…
Determining the efficiency of optical sources using a smartphone's ambient light sensor
2017
This work reports the use of a smartphone’s ambient light sensor as a valuable tool to study and characterize the efficiency of an optical source. Here, we have measured both luminous efficacy and efficiency of several optical sources (incandescent bulb and halogen lamp) as a function of the electric power consumed and the distance to the optical detector. The illuminance of LEDs as a function of the distance to the optical detector is characterized for different wavelength emissions. Analysis of the results confirms an inverse-square law of the illuminance with the detector–source distance and shows good agreement with values obtained by classical experiments. This experience will trigger …
Urban smart mobility in the scientific literature — bibliometric analysis
2018
Abstract This article aims at identification of the main trends in scientific literature characterising urban smart mobility, on the basis of bibliometric analysis of articles published in the ISI Web of Science and Scopus databases. The study period was set from 2000 to 2017. Authors used a basic technique of the bibliometric analysis of the scientific literature characterising urban smart mobility with the support of the VOSviewer software. The analysis included the number of publications, citation analysis, research area analysis and the most frequent keywords. The analysis led to taking notice of current research trends dealing with the urban smart mobility. The core of the paper is a t…
Mainstream digitale e altre immagini urbane. Una ricerca empirica nel sito UNESCO di Palermo
2021
The research deepens the role of new technologies in the construction of geographical imaginaries investigating the dimension of the offer related to the cultural heritage of the city of Palermo. The study was conducted using qualitative methods and provided for the application of two research techniques: participant observation and semi-structured interviews. By interpreting the results produced, the contribution aims to highlight the predominance of an urban image, linked to the UNESCO inclusion of the site in the World Heritage List, which is conveyed through new technologies. Developing a reflection on the alternative capacity of new media to dislocate and challenge shared images, the s…
Conceptualizing Core Aspects on Circular Economy in Cities
2021
Currently, there are many different interpretations in the literature of what a circular economy is and how it functions. As cities are still facing challenges to become fully sustainable, the need for a comprehensive analysis of how the circular economy can be implemented in urban areas is increasing. This article aims at outlining circular cities by their key characteristics and to further explore and provide a framework for fostering circularity at the city level. In order to achieve this goal, we performed a systematic review and analyzed key papers published in the field of circular economy to determine how circular economy practices form circular cities. We discovered that cities play…
Implementing a Digital Wellness Application into Use : Challenges and Solutions Among Aged People
2020
The ageing population is a growing priority area for policy makers and healthcare providers worldwide. Life expectancy is improving, but at the same time, insufficient physical activity threatens older age. Thus, an important question arises: how to improve the probability of people living a healthy and active life in older age. One potential solution to support physical activity and healthy aging is digital wellness technologies. However, digital wellness technologies are still typically designed for younger populations, yet a growing need and potential also among aged people is prevalent. Aged people are a user group with distinct needs and challenges. The main purpose of this study was t…
General Overview
2016
Il capitolo introduce alla tematica smart city attraverso un exscursus storico che ne traccia i passaggi salienti: la nascita delle politiche globali ambientali sino al livello della maturità raggiunto con il Protocollo di Kyoto (1997); poi ancora il Pacchetto Clima 20-20-20 redatto dalla Commissione Europea nel 2008 che traccia un'altro punto cruciale che prelude ai progetti e alle iniziative in ambito smart cities. La Strategia Energetica Europea al 2050 rappresenta il quadro di riferimento a cui tendere. Il capitolo si conclude con una rassegna dei sistemi di ranking più popolari e con una proposta di analisi. The chapter introduces to smart city issue through a historical excursus, whic…
Review of detection, assessment and mitigation of security risk in smart grid
2017
The integration of Information and Communication Technology (ICT) into the existing power grid has created new problems to the grid. The grid network has become more vulnerable to security threats and risk which is a corollary to the modern data network. Smart Grid has strict latency requirement for data communication and the violation of this latency is very costly. This paper assesses the threats and vulnerabilities associated with the Smart Grid network and reviews the methods to mitigate these security risks.
Experience from Indoor Fire Search and Rescue Game Design for Technology Testing
2018
No matter how good the fire evacuation plan for a building is, there is a risk of immovable victims being left behind due to smoke obscuration, inhalation of poisonous gasses, or other reasons. Firefighters usually perform the search and rescue for casualties in responding to fire hazards, besides the firefighting. Among of the challenges in the search and rescue operation is how to locate victims, and to keep monitoring the fire development so that it will not accidentally harm the fire personnel. This paper presents a game designed to test a smartphone app’s feature that supports concurrent tracking of indoor victims and fire spread. 22 volunteers were assigned roles either as rescuers or…
