Fuel cell-based hybrid cycles that include conventional power generators have been created to modify energy performance and output power. In the present paper, integrated biomass gasification (IBG)-molten carbonate fuel cell (MCFC)-gas turbine (GT) and steam turbine (ST) combined power cycle is introduced as an innovative technique in terms of sustainable energy. In addition, biomass gasificati...

this study was conducted to investigate the impact of podcasts as a learning and teaching tool on iranian efl learners’ motivation for listening as well as on their listening comprehension ability. the study also investigated the learners’ perception towards listening to podcasts and examined whether the learners were likely to accept podcasts. out of fifty-five intermediate learners studying e...

Abstract This study was conducted to reduce energy consumption and consumed electricity costs at drinking water pumping stations in villages located at the central part of Khorramabad city in 2017. In this study, 10 wells and pumping stations from a total of 48 wells and pumping stations in Khorramabad were selected randomly. The energy consumption, energy intensity, the effect of the capacito...

According to research, between 15 to 20 percent of the total energy consumption of every country is used for residential spaces. This amount is explanatory of the high cost and will follow the destruction of natural resources and environmental demolition. The aim of this research is to recognize earth thermal ability and its usage in public buildings and especially in private buildings in order...

Energy consumption in the residential sector is a complex socio-technical problem that can be explained using acombination of physical, demographic and behavioural characteristics of a house and its occupants. In this paper, byusing the energy consumption data for the residential sector of Shiraz in Iran, the effect of built area (BA) andoccupant number (Occ) on annual energy consumption (Ec) w...

Many transit providers changed their schedules and route configurations during the COVID-19 pandemic, providing more frequent bus service on major routes curtailing other routes, to reduce risk of exposure. This research first assessed changes in Metropolitan Atlanta Rapid Transit Authority (MARTA) by reviewing pre-pandemic versus during-pandemic General Feed Specification (GTFS) files. Energy ...

In the recent years, renewable energy sources are an important component of world energy consumption. GDP is one of the main measures of a country’s economic activity. Most of the studies examine the impact of renewable energy consumption on GDP with single equation model and the others use dynamic panel data. Since the Granger causality analysis’s findings of this paper establish bidirectional...

Building information modeling can help in predicting the energy efficiency in future based on dynamic patterns obtained by visualization of data. The aim of this study was to investigate the effective parameters of energy consumption using BIM technology which can evaluate the buildings energy performance. First, three forms of general states in the building were modeled to evaluate the propose...

this paper investigates the possibility of both linear and nonlinear effects of energy consumption on economic growth in iran, using data for the period of 1959–2007 based on threshold regression. some previous studies support the view that energy consumption may promote economic growth. however, the conclusion drawn from this study suggests that such relationship exists only where there is a l...
