IEEE/CAA Journal of Automatica Sinica 2023年第9期10卷 1845-1859页

作者： Agostino Marcello Mangini michele Roccotelli Department of Electrical and Information Engineering Polytechnic University of BariBari 70126Italy

About 60%of emissions into the earth’s atmosphere are produced by the transport sector,caused by exhaust gases from conventional internal combustion *** effective solution to this problem is electric mobility,which significantly reduces the rate of urban *** use of electric vehicles(EVs)has to be encouraged and facilitated by new information and communication technology(ICT)*** help achieve this goal,this paper proposes innovative services for electric vehicle users aimed at improving travel and charging *** goal is to provide a smart service to allow drivers to find the most appropriate charging solutions during a trip based on information such as the vehicle’s current position,battery type,state of charge,nearby charge point availability,and *** particular,the drivers are supported so that they can find and book the preferred charge option according to time availability and the final cost of the charge points(CPs).To this purpose,two virtual sensors(VSs)are designed,modeled and simulated in order to provide the users with an innovative service for smart CP searching and *** particular,the first VS is devoted to locate and find available CPs in a preferred area,whereas the second VS calculates the charging cost for the EV and supports the driver in the booking phase.A UML activity diagram describes VSs operations and cooperation,while a UML sequence diagram highlights data exchange between the VSs and other electromobility ecosystem actors(CP operator,EV manufacturer,etc.).Furthermore,two timed Petri Nets(TPNs)are designed to model the proposed VSs,functioning and interactions as discrete event *** Petri Nets are synchronized by a single larger TPN that is simulated in different use cases and scenarios to demonstrate the effectiveness of the proposed VSs.

Predicting the thermal conductivity of glasses from first principles has hitherto been a very complex *** established Allen-Feldman and Green-Kubo approaches employ approximations with limited validity—the former neglects anharmonicity,the latter misses the quantum Bose-Einstein statistics of vibrations—and require atomistic models that are very challenging for first-principles ***,we present a protocol to determine from first principles the thermal conductivityκ(T)of glasses above the plateau(i.e.,above the temperature-independent region appearing almost without exceptions in theκ(T)of all glasses at cryogenic temperatures).The protocol combines the Wigner formulation of thermal transport with convergence-acceleration techniques,and accounts comprehensively for the effects of structural disorder,anharmonicity,and Bose-Einstein *** validate this approach in vitreous silica,showing that models containing less than 200 atoms can already reproduceκ(T)in the macroscopic *** discuss the effects of anharmonicity and the mechanisms determining the trend ofκ(T)at high temperature,reproducing experiments at temperatures where radiative effects remain negligible.

Transient global amnesia and stroke: not that benign?

After more than 50 years since Fisher and Adams’original description in 1964,1 transient global amnesia(TGA)is still a puzzling *** time,several mechanisms have been proposed for TGA pathogenesis,including venous congestion,cortical spreading depression,seizures and arterial ischaemia.2–4 A sufficient amount of studies in favour and against each of these mechanisms has emerged,fostering uncertainty regarding aetiology as well as *** this extent,most of the controversy stands on whether TGA represents a risk factor for stroke,or whether this is just as benign as originally thought.
