This paper presents the contribution of electric vehicles to the distribution grid and railway station parking lots and their uncontrolled charging impacts on these grids. The economic indicators have been chosen as performance criteria. The benefits and advantages of using the charging/discharging coordination in sense of economic indicators have been evaluated by using mixed integer linear pr...

A principal provides budgets to agents (e.g., divisions of a …rm or the principal’s children) whose expenditures provide her bene…ts, either materially or because of altruism. Only agents know their potential to generate bene…ts. We prove that if the more “productive” agents are also more risk-tolerant (as holds in the sample of individuals we surveyed), the principal can screen agents and bols...

Solving many actual safety problems in atomic, electrotechnical, space, railway and oil industries as well as in science takes noncontact optical measurement technologies with micron resolution and productivity from 500 to 100 000 meas./s. We have developed, implemented and tested in real workshop and outside conditions some novel optical measuring systems, which are operating successfully in m...

Objectives The objective of this study was to identify the top 50 countries in the world in clinical neurology research and to use their data to assess the impact of a number of country-specific characteristics on scientific productivity in clinical neurology. Methods The SCImago Journal & Country Rank (SCR) web site was used to identify the top 50 countries in the world based on their total ...

The study proposes a new way of measuring productivity and efficiency, with and without considering environmental effects from a production activity, by modifying the conventional Luenberger productivity indicator. The Luenberger approach has so far been applied in productivity and efficiency measurement in time-varying contexts. It has been mainly used in comparisons of international productiv...

Communication and transportation networks are among the most important infrastructures critically involved in the development of different countries. The structural and tectonic position of Iran causes significant damage to its communication networks every year. Therefore, it is essential to adopt an integrated and flexible approach for assessing seismic risk in terms of available indicators. T...
