Abstract This qualitative analysis of peer observation practices is part of a larger, comparative case study, “Developing Human Capital Within Schools,” conducted by the Project on the Next Generation of Teachers. Within one city, we interviewed 142 teachers and administrators in six high-poverty schools (traditional, charter, and turnaround), all of which had achieved the highest rating in the...

The modest objective is to check the integrated effect of energy storage systems (ESSs) and distributed generations (DGs) compare optimization size location ESS DG explore its challenges for smart grids (SGs) modernization. research enlisted different algorithms cost-effectiveness, security, voltage control, less power losses. From this perspective, distribution network’s capacity are being per...

Distributed Generations (DGs) are utilized to supply the active and reactive power in the transmission and distribution systems. These types of power sources have many benefits such as power quality enhancement, voltage deviation reduction, power loss reduction, load shedding reduction, reliability improvement, etc. In order to reach the above benefits, the optimal placement and sizing of DG is...

Hybrid AC/DC microgrids facilitate the procedure of DC power connection into the conventional AC power system by developing the distributed generations (DGs) technologies. The conversion processes between AC and DC electrical powers are more convenient by hybrid systems. In this paper, an energy management system (EMS) for a hybrid microgrid network is proposed due to the optimal utilization of...

Increasing the short circuit current due to the penetration of distributed generations (DGs) in various voltage levels and meshed topology is a basic problem in power systems. Using fault current limiter (FCL) is an efficient approach to mitigate the exceeded short circuit levels. In this paper, a new approach is presented for multiple FCLs locating to decrease short circuit levels in meshed ne...

Constraint-based refactoring tools as currently implemented generate their required constraint sets from the programs to be refactored, before any changes are performed. Constraint generation is thus unable to see — and regard — the changed structure of the refactored program, although this new structure may give rise to new constraints that need to be satisfied for the program to maintain its ...

After the first wave of feminist geographical research, which focused on the spatiality of women’s lives, feminist geography began to concern itself with issues of equity in the discipline, the ways in which geographical knowledge is conceptualized, and how gender and other social differences interrelate. In this paper I consider how the current generation of women graduate students, students w...

This paper provides a summary of what is known from social science research about the effects parents have on the donations of their children. It then goes on to summarize two on-going research projects. The first project provides estimates of the strength of the relationship between the charitable giving of parents and that of their adult children. The second provides estimates of the effect o...
