Proton exchange membrane (PEM) fuel cells being employed in fuel cell vehicles (FCVs) are promising power generators producing electric power from fuel stream via porous electrodes. Structure of carbon paper gas diffusion layers (GDLs) applying in the porous electrodes can have a great influence on the PEM fuel cell performance and distribution of temperature, especially at the cathode side whe...
the present study is based on the assumption that the more the women enjoy the cultural capital, the higher their position in the power structure of the family and the more their bargaining power. for evaluating the aforementioned theory, the required data were attained through survey methodology and questionnaire tool and by selecting a sample of 385 married women resided in shiraz. the sampli...
This paper presents a hierarchical control strategy for heat and electric power control of a building integrating hybrid renewable power sources including photovoltaic, fuel cell and battery energy storage with Plug-in Electric Vehicles (PEV) in smart distribution systems. Because of the controllability of fuel cell power, this power sources plays the main role for providing heat and electric p...
throughout history “family” has undergone changes. among the factors affecting these changes are the increasing participation of women in public areas and entering the world of employment. when women were employed and left homes it transformed the form of traditional family life and power structure between men and women in the family interactions was changed. in this paper the influence of wome...
the present study is based on the assumption that the more the women enjoy the cultural capital, the higher their position in the power structure of the family and the more their bargaining power will become. for evaluating the aforementioned theory, the required data were attained through survey methodology and questionnaire tool and a sample size of 385 married women residing in shiraz was se...
This paper presents a novel control approach used in shunt active power filter based on variable structure control combined with Random PWM technique (RVSC) that provides robust, fast, and more favorable performance for active power filter. This control strategy is compared with two other strategies to show the effectiveness of the introduced methods; pulse width modulated proportional-integral...
In this paper, a new structure for buck-boost Z-source converter based on Z-H topology is proposed. The proposed converter consists of two LC networks similar to the conventional Z-source and Z-H converters. One of the characteristics of the proposed structure is that, without any changing in its’ power circuit, it can be used in different conversions such as dc/dc, dc/ac and ac/ac. This unique...

This paper introduces a novel silicon-on-insulator (SOI) metal–semiconductor field-effect transistor (MESFET) with an implanted N layer (INL-SOI MESFET) to improve the DC and radio frequency characteristics. The DC and radio frequency characteristics of the proposed structure are analyzed by the 2-D ATLAS simulator and compared with a conventional SOI MESFET (C-SOI MESFET). The simulated result...
extended abstract 1.introduction relationship pattern has a complex, combinational and also intelligible nature in the current geopolitical structure of the world. civilizations’ relations together and civilization interactions include: engagement, competition and conflict in a range of geopolitical treatment pattern. some of spatial values which originated challenges among region country have ...
