The hydrogen production rate in a microbial electrolysis cell (MEC) using a non-buffered saline catholyte (NaCl) can be optimized through proper control of the initial anolyte pH and catholyte NaCl concentration. The highest hydrogen yield of 3.3 0.4 mol H2/mole acetate and gas production rate of 2.2 0.2 m H2/m/d were achieved here with an initial anolyte pH 1⁄4 9 and catholyte NaCl concentrati...

The purpose of this research is to found the impact of built area and occupant number on winter gas consumption in the residential building sector of Iran, Shiraz.Sothe annually and monthly gas consumption data through 19 houses were analyzed to achieve the heating energy consumption and operation month.The average operation months of gas heating consumption were from first of November up to en...

Anaerobic bacteria were isolated from industrial wastewater and soil samples and tested for exoelectrogenic activity by current production in double chambered microbial fuel cell (MFC), which was further transitioned into a single chambered microbial electrolytic cell to test hydrogen production by electrohydrogenesis. Of all the cultures, the isolate from industrial water sample showed the max...

this present research work was carried out to evaluate the energy consumption in a typical iranian building based on the forecast of climatic variables. thus, the lars-wg model was validated for some northwest stations of iran, including tabriz, ardebil, oromieh, kermanshah, hamedan, sannandaj, qazvin, and zanjan. the average monthly outdoor temperature was forecasted from 2011 to 2100. the rel...

thin layer drying of russian olive (elaeagnusan gastifolial l.) fruit using a hot air dryer in order to calculate effective moisture diffusivity, activation energy and energy consumption has been evaluated in this article. the selected variables included three levels of air velocity of 0.5, 1 and 1.5 m/s and three air temperature levels of 50, 60 and 70°c. increased air temperature increased ef...

In a mobile edge computing (MEC) network, devices, also called clients, offload their computations to multiple servers that provide additional resources. Since the are placed at network edge, e.g., cell-phone towers, transmission delays between and clients shorter compared those of cloud computing. addition, can tasks other nearby with available resources by exploiting Fog Computing (FC) paradi...

In this computational research, the separate and simultaneous impacts of diesel direct injection timing, fuel spraying cone angle, and hydrogen gas addition on combustion characteristics, output emissions, and performance in a single-cylinder direct injection diesel engine was studied. In order to conduct the simulations, valid and reliable models for combustion, break-up, and for turbulence wa...

Because of extreme sensitivity to time and energy consumption, many computation- data-intensive tasks are difficult implement on mobile terminals cannot meet the needs rapid development networks. To solve this problem, edge computing (MEC) appears be a promising solution. In study, we propose two offloading schemes in multiple unmanned aerial vehicles (UAVs) enabled MEC network. Their optimisat...

The improvement of the energy efficiency and reduction latency are two main goals next generation Radio Access Networks (RANs). In order to achieve latter, Multi-access Edge Computing (MEC) is emerging as a promising solution: it consists placement computing storage servers, directly at each Base Station (BS) these networks. For RAN efficiency, dynamic activation BSs considered an effective app...
