Design and performances of a high temperature superconducting axial flux generator
2013
An important quality index of electric machine is the power density: it is known that axial flux machine tends to have a higher power density than the radial machines. As a result they are becoming more and more used in applications where the power density is a critical issues. However, the best way to enhance the power density is to increase the value of the airgap field and this could be achieved by using a superconducting excitation. Many projects have been developed in the world in order to develop both superconducting generator and superconducting motor, but in most of these programs the geometry of the machine has been based on radial machines [1]. All of these approaches show the fea…
Cooperation among competitors: A comparison of cost-sharing mechanisms
2016
Abstract In this paper, we investigate the consequences of using outcome-based versus ex ante-based cost-sharing mechanisms in terms of competing firms' profitability and total welfare. We consider two firms making a joint expenditure, which can positively affect firms' demand and/or unit operating costs, while competing in the final market by setting either price or quantity. We compare two outcome-based cost-sharing mechanisms, i.e., Quantity Proportional (QP) and Total Margin proportional (TM), with the more competitive Fixed Share (FS) mechanism where cost-sharing is set up on an ex ante basis. We show that outcome-based mechanisms, and even a fully collusive behavior induced by the opt…
Studio di alcuni aspetti della domanda di arance bionde mediante la Cluster Analysis. Il Caso delle arance di Ribera dop e possibili strategie di mer…
2012
In a time of evolution of demand towards new features and new functions for food, both producers and consumers focus more and more on human health and on environmental protection. The citrus industry has not escaped these changes in demand, also because of the eu policies that have led to greater use of the processed product at the expense of fresh one. Sicily, which for these productions has higher quality standards than its competitors, aims to develop the sector, with investments in promotion, brand protection and quality certifications, with the introduction of the dop "Arancia di Ribera". In this context Sicilian producers of oranges are aware that it's very important to pay attention …
Il ruolo delle Tecnologie Informatiche e di Comunicazione e della logistica distributiva sulla competitività del comparto ortofrutticolo siciliano
2012
In recent years, the market globalization process has deeply changed the international competitive background, leading, inevitably, to a revision of the strategies and the organization structures of the companies. It is now widely accepted that Information and Communication Technology (ICT) and supply chain logistics management, have an important role in the increasing of the competitive potential of each company and in the development of entire economic sectors. The importance of these factors in the business strategies of the firms, has generated an increasing attention by the research world to the study of the economic and social impact, both about the spread of modern information and co…
Radical innovations: Between established knowledge and future research opportunities
2021
Abstract The fast growing body of radical innovation research is fragmented and difficult to overlook. We provide an overview of the most cited journals, authors, and publications and conduct a bibliographic coupling to structure the literature landscape. We identified the following research clusters: management of radical innovations, organizational learning and knowledge, financial aspects of radical innovation, radical innovation adoption and diffusion, radical industry innovations as challenges for incumbents, and radical innovation in specific industries. Based on an in-depth content analysis of these clusters, we identify the following future research opportunities: A systematic compi…
Competing R&D Joint Ventures in Cournot oligopoly with spillovers
2014
This paper considers competition between R&D cartels, whereby prospective Cournot competitors coordinate their R&D decisions in order to maximize joint profit. It studies how R&D activity, aggregate profit, consumer surplus, and social welfare vary as the number of competing cartels varies. It also compares equilibrium with second best R&D, and discusses the policy implications of the results. The results show that the effects of R&D cartel competition depend on the welfare criterion adopted and on whether there are cooperative synergies or not.
Quality pricing-to-market
2014
We examine firm's pricing-to-market decisions in vertically differentiated industries featuring a large number of firms that compete monopolistically in the quality space. Firms sell goods of heterogeneous quality to consumers with non-homothetic preferences that differ in their income and thus their marginal willingness to pay for quality increments. We derive closed-form solutions for the pricing game under costly international trade, thus establishing existence and uniqueness. We then examine how the interaction of good quality and market demand for quality affects firms' pricing-to-market decisions. The relative price of high quality goods compared to that of low quality goods is an inc…
Electoral vulnerability and size of local governments: Evidence from voting on municipal mergers
2014
Abstract We analyze how anticipated changes in the electoral vulnerability of municipal councilors affect their voting behavior over municipal mergers. The electoral vulnerability changes due to a merger because it changes the composition of political competitors and the number of available seats in the next election. We use this variation for identification and find that the smaller the increase in the electoral vulnerability of a councilor, the more likely he is to vote for the merger. The documented effect is not driven by the behavioral response of the voters, or by party-line considerations. The councilors' desire to avoid personal electoral competition may lead to sub-optimally small …
Control and design for efficiency improvement of permanent-magnet synchronous motor drives in household appliances
2011
This paper deals with some aspects of efficiency improvement of PMSMD (Permanent Magnet Synchronous Motor Drives). Particularly two aspects are focused: the control algorithm for the PMSMD, which allows to reduce the power losses of the electric drive without penalty on its dynamic performances and the optimization of an IPMSM (Interior Permanent Magnet Synchronous Motor) rotor configuration capable to increase the performances in terms of shaft torque production, limiting at the same time the rotor leakage flux. The loss minimization algorithm is here briefly analyzed, a test bed for experimental validation is presented and the data are analyzed. Experimental tests have been performed aimi…
Replacement of Vehicle Fleet with EVs Using PV Energy
2016
The diffusion of Electric Vehicles (EVs), the reduction of environmental pollution and the production of energy from renewable sources (RES), in particular photovoltaic system, wind farm, hydroelectric plants, bioenergy and geothermal plants are the principal aspects discussed in the world. For this reason, the goal of this work is to study for 2014 year in all Italy's Regions; the energy production obtained to photovoltaic systems (PV) and the possibility to use with different percentage this energy for recharge the electric vehicles. In particular, they have been considered different scenarios in function to the km travelled per year from the population. This paper examines the integratio…
