Abstract: A fuelcell stack produces a low and unregulated dc voltage; therefore, a dcdc converter is required to step up and regulate the output voltage. A major drawback is that the output voltage of the fuelcell stack exhibits a ...

Abstract: Mixing ratio data of water vapor at different hours of the day in a high-altitude tropical plateau in Mexico are shown. The objective is to measure water vapor quantity in a mountainous zone, where no previous studies of ...

Abstract: This study explores the structure of liquid/gas coaxial jets under forced and unforced conditions. The forcing is in the form of a transverse acoustic resonance within the confined space where the mixing occurs. The studied ...

Abstract: Seven cycles of operation in relation to the filling ratio, mixed liquor suspended solids (MLSS), hydraulic retention time (HRT), and temperature were studied in a pilot-scale experimental plant of a hybrid moving bed ...
