Electric vehicles (EVs) are instrumental in balancing the operation of the transportation networks and grids for the dual attribute of power and traffic load. Current research community has gained significant efforts on key technologies for the integration of electric vehicle-charging station-transportation network-grid (VSNGI). Therefore， a synthetic review on this domain is needed. In this context， the VSNGI research included in the web of Science (WOS) was synthetically analyzed using bibliometric methods， the software VOSviewer and CiteSpace. The results show that the internationally interested VSNGI research is in a period of rapid development in terms of publication volume， national， institutional， and journal performance. The cited literature provided work accumulation in five aspects: “the impact and control of EVs on the grid”， “design of EV charging stations”， “integration of charging stations and grids”， “integration of charging stations and transportation networks” and “coupling of the transportation network and grid”. Then， the latest progress was summarized in four aspects: “characterization methods of spatiotemporal features of road network demand and grid load”， “SNG collaborative layout technology”， “VSN orderly guidance technology”， and “VNG interactive response technology”. Lastly， the problems and prospects in the VSNGI research were discussed. The joint efforts of researchers from multiple disciplines are required by the development of the VSNGI field. The VSNGI research will be of crucial significance in the transformation of the transportation field.

Journal of Traffic and Transportation engineering(English Edition) 2024年

Driving for a long time can lead to fatigue， which can affect information processing and decision-making， potentially threatening driving safety. By exploring the generation and variation patterns of driving fatigue and clarifying the application status of its detection and warning technology， traffic safety can be improved. In order to understand the research progress of driving fatigue， based on the web of Science core database， this paper obtained 2127 English literature published from 1998 to 2023 (as of May 12， 2023)， covering a total of 5963 authors and 6019 keywords， and the bibliometric tool VOSviewer and R-Bibliometrix are used to analyze the literatures. Firstly， the literature statistical analysis is carried out from annual distribution， country distribution， source journals， and core authors. Secondly， the research hotspots and trends are analyzed from keywords co-occurrence， high-impact literature， theme evolution， and development trends. Finally， the development trend of driving fatigue research is discussed. The result shows that the hotspots in the field of driving fatigue include driving fatigue detection， fatigue driving risk and fatigue research of professional drivers， driver alertness and coping strategies for driver fatigue， and driver fatigue under automatic driving. And the improvement of the accuracy and reliability of driving fatigue detection will be the difficult point to break through in the future. It is necessary to build a multi-disciplinary and meticulously quantified driving fatigue and its risk assessment system， and strengthen the control of fatigue risks. research on intervention measures and education training for professional drivers needs to be deepened， while exploring the acceptance and compliance of intervention measures. Moreover， the evolution law and prevention strategies of driver fatigue under automatic conditions should be the focus of future research.

Tests Management in CALIPSOneo: A MDE Solution

引用

Journal of Software engineering and Applications 2014年第6期7卷 506-512页

作者： Alberto Salido Julian Alberto Garcia Garcia Jose Ponce Javier Jesus Gutierrez Software engineering and early testing group Universidad de Sevilla Sevilla Spain

testing in Software engineering is one of the most important phases although, unfortunately, it cannot be always successfully fulfilled due to time constraints. In most cases, the development phase takes more time than it was estimated, entailing negative effects on the testing phase. The delay increases even more in research and Development (R + D) projects, where the real time to execute tasks is more difficult to control. Model Driven engineering (MDE) offers a solution to avoid testing costs without affecting the execution quality of the applied test. This paper presents a practical overview of a Model Driven testing (MDT)-based methodology and its impact on CALIPSOneo project, which was carried out in liaison with Airbus Defense and Space and, particularly, with the Product Lifecycle Management (PLM) department.

The studypresents theHalfMax InsertionHeuristic (HMIH) as a novel approach to solving theTravelling SalesmanProblem (TSP). The goal is to outperform existing techniques such as the Farthest Insertion Heuristic (FIH) andNearest Neighbour Heuristic (NNH). The paper discusses the limitations of current construction tour heuristics,focusing particularly on the significant margin of error in FIH. It then proposes HMIH as an alternative thatminimizes the increase in tour distance and includes more nodes. HMIH improves tour quality by starting withan initial tour consisting of a ‘minimum’ polygon and iteratively adding nodes using our novel Half Max *** paper thoroughly examines and compares HMIH with FIH and NNH via rigorous testing on standard TSPbenchmarks. The results indicate that HMIH consistently delivers superior performance, particularly with respectto tour cost and computational efficiency. HMIH’s tours were sometimes 16% shorter than those generated by FIHand NNH, showcasing its potential and value as a novel benchmark for TSP solutions. The study used statisticalmethods, including Friedman’s Non-parametric Test, to validate the performance of HMIH over FIH and *** guarantees that the identified advantages are statistically significant and consistent in various situations. Thiscomprehensive analysis emphasizes the reliability and efficiency of the heuristic, making a compelling case for itsuse in solving TSP issues. The research shows that, in general, HMIH fared better than FIH in all cases studied,except for a few instances (pr439, eil51, and eil101) where FIH either performed equally or slightly better thanHMIH. HMIH’s efficiency is shown by its improvements in error percentage (δ) and goodness values (g) comparedto FIH and NNH. In the att48 instance, HMIH had an error rate of 6.3%, whereas FIH had 14.6% and NNH had20.9%, indicating that HMIH was closer to the optimal solution. HMIH consistently showed superior performanceacross many benchmarks,

Linear and non-linear pseudocapacitances with or without diffusion control

引用

Progress in Natural Science:Materials International 2021年第6期31卷 792-800页

作者： George Zheng Chen Department of Chemical and Environmental engineering and Advanced Materials Research Group Faculty of Engineering University of Nottingham

Pseudocapacitance is an important reversible charge storage mechanism in many electrode materials. Although the concept was first proposed in early 1960s, it has been more widely studied following the observation of rectangular cyclic voltammograms(CVs) when testing some transition metal oxides and electronically conducting polymers, and the association with supercapacitor. However, interpretation of pseudocapacitance is inconsistent in the literature. Although all agree that materials are pseudocapacitive if they undergo Faradaic reactions and exhibit rectangular CVs, some have regarded any surface confined Faradaic reactions which may present non-rectangular or even peak-shaped CVs to be pseudocapacitive. In the case of rectangular CVs, the amount of charge stored in the electrode is a linear function of the electrode potential, whilst for non-rectangular or peakshaped CVs, the relationship is non-linear. It is shown in this article that only linear pseudocapacitance is of relevance to supercapacitor, but non-linear pseudocapacitance may find applications in rechargeable battery and supercapattery. Further, it is clarified that the equation i = kv + kvis useful in analysis of electrode kinetics in terms of surface confinement and diffusion control. However, this kinetic equation is blind to the thermodynamically determined charge storage mechanisms as shown by experimental evidence, and should not be used to differentiate non-capacitive Faradaic processes from pseudocapacitance, either linear or non-linear.
