Time Series Corrections and Analyses in Thermal Remote Sensing
2013
The time span of surface thermal data bases now reaches a few decades. However, studies using surface thermal time series are seldom, due to the difficulty of obtaining temporally coherent estimations for this parameter. Applications for surface thermal multitemporal analysis range from climate change studies and modeling to anomaly detection for natural or industrial hazard detection. This chapter presents methods to improve the temporal coherence of temperature time series, through data reconstruction of atmospheric and cloud contaminated observations, and through the correction of the orbital drift effect which hinders the use of the longest data sets. Then, methods for the analysis of t…
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…
Guest Editorial Special Section on Recent Trends and Developments in Industry 4.0 Motivated Robotic Solutions
2018
The twelve papers in this special section focus on the development of robotic solutions for smart factories in industry - the concept of the fourth industrial revolution (industry 4.0). The inclusion of robotics is expected to deeply change the future manufacturing and production processes, and lead to smart factories that will benefit from the main design principles of Industry 4.0: interoperability, virtualization, decentralization, real-time capability, service orientation, and modularity. Robotics will have a key role in this development since innovative technologies and solutions, traditionally associated with the service robotics sector, are going to migrate to industrial smarter robo…
Breaking layer 2: A new architecture for programmable wireless interfaces
2012
This paper introduces a new architecture for programmable wireless interfaces, aiming at responding to the emerging request of wireless access flexibility and adaptability. Instead of implementing a specific MAC protocol stack, the proposed architecture supports a set of programmable services, devised to customize the wireless access operations according to specific network and application scenarios. The services are composed by means of simpler functions, which in turns work on system primitives (i.e. elementary non-programmable functionalities, natively provided by the system) dealing with the physical transmission and reception of the frames. Our approach significantly differs from softw…
A Simulation Analysis for Assessing the Reliability of AC/DC Hybrid Microgrids - Part I: Underground Station and Car Parking
2021
This paper reports the results of a simulation study with the aim of evaluating the capability of two portions of a hybrid AC/DC MV/LV network of maintaining their operation in off-grid mode during the loss of the main AC grid due to a failure. In particular, the study aims to verify, in the case of islanded operation of the two microgrids, the continuity of the electricity service by exploiting the local generation plants, Energy Storage Systems (ESSs), and other flexible resources managed by suitable algorithms in different energy scenarios. The analysis was carried out considering two microgrids: an underground station and a car parking with Electric Vehicles (EVs). For assessing the per…
Applied study on the rotational molding and processing technology of rotational molds
2021
Computer-aided manufacturing involves a set of computerized activities related to the preparation, launch and follow-up of manufacturing. Computer-aided manufacturing is a tool that allows the use of 3D models based on computer-aided design. This paper addresses the process of rotational formation, with an effective focus on the technology of processing a rotational mold using CAM simulation as a research method. In this sense, the right choice of CNC and cutting tools is essential. The use of numerically controlled machine tools and high-performance cutting tools reduces the number of operations. The manufacturing route realized is specific to the parts machining on numerical control machi…
Contributo alla conoscenza del comportamento dei setti caricati orizzontalmente
2008
Si illustrano e si discutono i risultati di una prova di carico a rottura eseguita su un setto in vera grandezza realizzato in terreni sabbiosi. Il comportamento del sistema setto-terreni è fortemente non lineare a partire da valori del carico applicato dell’ordine di 1000 kN. Il carico orizzontale limite si raggiunge per valori dello spostamento in corrispondenza della testa del setto dell’ordine dei 10 cm, ed è principalmente governato dalla resistenza flessionale della sezione trasversale del setto.
EFFECT OF PASSIVE ATMOSPHERE AND CHEMICAL TREATMENT ON FRESH CUT OF WHITE-FLESH PEACH CULTIVAR 'SETTEMBRINA DI BIVONA'
2015
Peach germplasm in Italy includes white- and yellow-flesh peaches, all of them characterized by a persistent aroma and an excellent flavor. However, their behavior, in terms of postharvest maintenance and suitability for minimal processing, has never been investigated. The aim of this study was to investigate the effects of passive atmosphere and chemical treatment, with 2% ascorbic acid and 1% calcium lactate, in order to prevent fruit browning and to maintain the quality of fresh cut slices of the white-flesh peach cultivar ‘Settembrina di Bivona’. To achieve a passive atmosphere condition, approximately 150 g of peach fruit slices were placed in rigid bi-oriented polystyrene bags and sto…
CHEMICAL AND SENSORY CHARACTERISTICS OF FIVE LOQUAT CULTIVARS
2015
Fruit quality can be evaluated by combining chemical-physical and sensory analyses. In this trial, both instrumental and sensory analyses were carried out on fruit of 5 loquat cultivars (âNespolone di Trabiaâ, âSanfilipparaâ, âVirticchiaraâ, âMarcenA²â and âGolden Nuggetâ), with the aim of assessing their commercial quality. Fruit weight, transversal and longitudinal diameter, total soluble solid content (TSS), and titratable acidity (TA) were measured. In addition, a sensory profile of each cultivar was defined by a trained panel, which generated 16 attributes. The highest fruit weight was found in âGolden Nuggetâ and âSanfilipparaâ; the latter exhibited also th…
