After almost 5 years of operation, ESA’s International Gamma-Ray Astrophysics Laboratory (INTEGRAL) Space Observatory has unveiled a new soft Gamma ray sky and produced a remarkable harvest of results, ranging from identification of new high energy sources, to the discovery of dozens of variable sources to the mapping of the Aluminum emission from the Galaxy Plane to the presence of electrons a...

based on the problems caused by today conventional vehicles, much attention has been put on the fuel cell vehicles researches. however, using a fuel cell system is not adequate alone in transportation applications, because the load power profile includes transient that is not compatible with the fuel cell dynamic. to resolve this problem, hybridization of the fuel cell and energy storage device...

With the development of renewable energy sources (RES), use microgrids is becoming more prevalent. The low voltage direct current (LVDC) microgrid provides numerous advantages, including increased convenience, improved efficiency, loss reduction, and simple integration with PV BESS. There are currently no perfect fault detection methods for LVDC microgrids. Solutions, such as protection relays ...

e nergy consumption has increased significantly in iran during the recent decades. in this study, an inter-industrial model has been improved to investigate the sources of the changes in the energy consumption of the country. the input-output tables of iran for the years 1988 and 2001 have been employed as the database of the model. the innovation of this research allows the researchers to stud...

Executive Summary In the 21st century new sources of energy will be needed across the globe, as easily available fossil fuels are exhausted, as we try to minimize the adverse environmental and other costs of fossil fuel extraction, and as we move towards fully sustainable energy sources. New sources of energy will both enable and require major transformations in the communities in which they ar...

Thermal energy storage (TES) is capable to reduce the demand of conventional energy sources for two reasons: First, they prevent the mismatch between the energy supply and the power demand when generating electricity from renewable energy sources. Second, utilization of waste heat in industrial processes by thermal energy storage reduces the final energy consumption. This review focuses mainly ...
