Efficiency optimization in bi-directional inductive power transfer systems
2015
Inductive Power Transfer (IPT) allows to wirelessly supply electronic devices. Thus, it is a very smart technique of battery charging for electric vehicles. In a parking area scenario, IPT is a proper method aiming at the energy transfer from the vehicle battery to the electric grid too. Bi-Directional Inductive Power Transfer (BDIPT) Systems are an attractive solution for the automotive market. Due to the great relevance of the energy saving problem, the goal of an efficiency maximization is researched by the energy market. In this paper, an in-depth investigation of the power efficiency in BDIPT systems is carried out, aiming at the optimum efficiency.
Experimental test on a Contactless Power Transfer system
2014
Contactless Power Transfer (CPT) is an ever-growing technology in automotive market, due to the significant improvement brought by it to battery charging operation in terms of safety and comfort. CPT is based on inductive coupling between two coils, so that power cords can be avoided for vehicles battery charging and an important contribution towards a smarter mobility can arise. In this paper, a CPT prototype for E-bike is proposed. Magnetic design and power electronics system are described. Experimental results deriving from laboratory tests are presented and power efficiency of the system is addressed.
Different scenarios of electric mobility: Current situation and possible future developments of fuel cell vehicles in Italy
2020
The diffusion of electric vehicles in Italy has started but some complications weight its spread. At present, hybrid technology is the most followed by users, due particularly to socioeconomic factors such as cost of investment and range anxiety. After a deep discussion of the Italian scenario, the aim of the paper is to recognize whether fuel cell technology may be an enabling solution to overcome pollution problems and respect for the environment. The opportunity to use fuel cells to store electric energy is quite fascinating&mdash
Sharing-collaborative economy in tourism: A bibliometric analysis and perspectives for the post-pandemic era
2021
Sharing economy research has risen exponentially during the last 4 years. Although several theoretical revisions on this topic have been developed, a conceptual analysis based on bibliometric techniques and science mapping tools is lacking. Within this framework, this article has two aims: (i) to carry on a performance analysis to identify the outstanding themes and (ii) to visually present the scientific structure by topics of research in sharing-collaborative economy as well as its evolution to identify future directions. The resources in the Web of Science Citation Index were used. Intelligent techniques and, more specifically, the SciMAT tool (based on co-word analysis and h-index anal…
Interplays Between Corporate Reputation And Media – A Bibliometric Analysis
2020
Abstract As strategic asset – determinant of sustained competitiveness – corporate/firm reputation has a very distinctive feature that sets it apart: although reflection of (better, worse or not at all performed) reputation management at a company’s level, it is rather a “representation” / “perception” – built on a business’s previous behaviors, but more precisely on the ways its different stakeholders have interacted (acknowledged, internalized, resonated) with them – in a (sometimes unconscious) process highly mediated and moderated by the media. Thus, the current study aims to explore the interplays between corporate/firm reputation and media as they are reflected in the scientific liter…
Social entrepreneurship and Economy for the Common Good: Study of their relationship through a bibliometric analysis
2019
Being social entrepreneurship (SE) the closest to Economy for the Common Good (ECG) principles, our work proposes to analyze the contribution of ECG model to SE. It is also intended to establish the relationship that exists between both concepts. Therefore, our specific objectives are to (1) identify the specific contributions of ECG principles to SE as well as their overlaps, (2) perform a literature review to analyze and quantify the number of research papers on SE and ECG, and (3) identify the possible existing gap. Through a double methodology, we (1) determine the potential contributions of the ECG model to SE, we propose to analyze the Common Good (CG) matrix and (2) empirical analys…
The Rise of Social Media in Sport: A Bibliometric Analysis
2020
Social media has revolutionized the sports industry by changing the way athletes, coaches, clubs, federations, sport companies and other industry actors interact. Although academic interest in the emergence of social media in the context of sports has increased in recent years, these platforms have not been studied from a bibliometric viewpoint. Therefore, this study examined the scientific production of social media in sports using descriptive bibliometric software. The most prolific authors, journals, institutions, number of citations and networks of authorship are identified. From the bibliometric analysis, implications for sport managers and future research directions for social media …
Corruption in international business: A review and research agenda
2020
Abstract We systematically reviewed the literature on corruption in international business (137 articles) for the last 17 years between 1992 and 2019. Additionally, we identified seven research streams in this growing literature: (1) the legislation against corruption, (2) the determinants of corruption, (3) combating corruption, 4) the effect of corruption on firms, (5) the political environment and corruption, (6) corruption as a challenge to existing theories of management, and (7) the effect of corruption on foreign direct investment and trade. Based on this review, we recommend that strong international laws are needed to minimize the negative impact of corruption on international busi…
Choosing Optimal Seed Nodes in Competitive Contagion.
2019
International audience; In recent years there has been a growing interest in simulating competitive markets to find out the efficient ways to advertise a product or spread an ideology. Along this line, we consider a binary competitive contagion process where two infections, A and B, interact with each other and diffuse simultaneously in a network. We investigate which is the best centrality measure to find out the seed nodes a company should adopt in the presence of rivals so that it can maximize its influence. These nodes can be used as the initial spreaders or advertisers by firms when two firms compete with each other. Each node is assigned a price tag to become an initial advertiser whi…
Mining customer requirements from online reviews: A product improvement perspective
2016
We propose a filtering model to predict helpfulness of reviews for product design.We provide a way to use the KANO model based on online reviews.We explore how to obtain insights from Big Data through knowledge-based view. Big data commerce has become an e-commerce trend. Learning how to extract valuable and real time insights from big data to drive smarter and more profitable business decisions is a main task of big data commerce. Using online reviews as an example, manufacturers have come to value how to select helpful online reviews and what can be learned from online reviews for new product development. In this research, we first proposed an automatic filtering model to predict the help…
