Multiphase machine drives
No full textVariable-speed AC drives are nowadays based on three-phase electrical machines fed by power electronic converters acting as power interface between the electrical machine and AC or DC power sources. Nevertheless, in the last two decades the multiphase electrical drives have become an interesting alternative for particular applications. However, the application of multiphase drives is still limited, mainly due to their complexity and control that somehow make them more difficult to handle with respect to the conventional three-phase counterparts. Therefore, this work intends to be a useful tool to disseminate the fundamental concepts of multiphase drives to students and application engineers
Saving Education Received in Early Life and Future Orientation in Adulthood
No full textWe use data from a Dutch data set, the DNB Household Survey, annually covering the period 1996-2015, to study the relationship between informal parental saving education received when people were children or adolescents and two variables aimed to capture adult individuals’ concerns for their future: planning horizon and future orientation. Our results indicate that the general future orientation positively correlates with informal saving education, and in particular having received financial teachings. Our findings also suggest that the future orientation index is rather stable over time (which is not trivial, especially because our dataset covers two full business cycles) and declines with age following the life-cycle

The Art City as a Local Public Good: the Strategic Interplay Between Private Donors and Art Organizations
No full textSocial preferences and private provision of public goods: A 'double critical mass' model
No full textWe set up an evolutionary game-theoretic model aimed at addressing the issue of local public good provision via direct commitment of voluntary forces (private donors and nonprofit providers) only. Two classes of agents are assumed to strategically interact within a 'double critical mass' model and we investigate the critical factors affecting the dynamic outcomes of such interaction. Further, we explore the conditions under which (what we term) 'evolutionary crowding-out/in' occurs, depending on agents' degree of opportunism, social comparison and positive selective incentives (such as subsidies given by the government to 'virtuous' citizens or nonprofits only)
