Exploring Particle Swarm Optimization to Build a Dynamic Charging Electric Vehicle Routing Algorithm
No full textElectric vehicle (EV) limited range is a serious concern for its wide scale commercialization. Dynamic battery charging is being developed as a promising technology for increasing the range, vehicles are charged through inductive points placed in the net. The choice of a proper navigation route becomes essential, and algorithms must be identified for a run time identification of the better path. In this paper, we propose and explore the application of the particle swarm optimization (PSO) algorithm to solve the problem of energy efficient routing problem for inductive dynamic charging EVs. The paper presents the results obtained in a simple simulation of a road network with 11 dynamic charging inductive lanes
Developing ICT Solutions for Dynamic Charging of Electric Vehicles
No full textDynamic charging technology has the potential to solve the range anxiety problem of electric vehicles. The FABRIC project is assessing the feasibility of using the dynamic charging technology on a large scale. The project developed the ICT platform to support dynamic charging. This paper presents some ICT systems developed within FABRIC
Maximizing Power Transfer for Dynamic Wireless Charging Electric Vehicles
No full textDynamic (on the go) wireless electrical charging is a new, challenging frontier for vehicular technologies, as it would allow a dramatic increase in the feasible distance range of electrical vehicles. This paper presents a system under development for optimizing the power transfer for dynamic charging vehicles. The system relies on a coil coupling sensor and a camera. The coupling sensor measures the coupling level between the road and vehicle coils, while the camera detects the distance of the vehicle from the two lines of the lane. A sensor fusion system is needed because, on one hand, the coil sensor is highly accurate but cannot distinguish the direction of the misalignment, while the camera is less precise but can provide information about the position of the lane center, where the centroid of the transmitting coil is expected to be and complete a series of other non-magnetic information needed like the obstacle presence
Information and Communication Technology Research Opportunities in Dynamic Charging for Electric Vehicle
No full textDynamic charging of electric vehicle technology aims to deploy the use of electric vehicle on a large scale. In order to realize and achieve an effective and reliable system, the information and communication solutions (ICT) need to be developed. The ICT solutions look particularly to assess areas such as routing, booking of the charging lane, billing, vehicle identification, guidance to charging lane and assistance while charging. In this paper, we review the state of the art of ICT solutions and provide indications for the future research
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
