conventional sand filtration which has become a common wastewater treatment technology to satisfy regulations appointed for effluent reuse, suffers from the disadvantage of high energy for backwashing. the subject of this study is application of downflow floating media prior to coarse sand filtration, which requires less water for backwash. two pilots have been employed in two stages. for the f...

In this work, we consider a 1-bit quantized Massive MIMO channel with superimposed pilots (SP), dubbed “QSP”. With linear minimum mean square error (LMMSE) channel estimator and maximum ratio combining (MRC) receiver at the BS, we deive an approximate lower bound on the ergodic achievable rate. When optimizing pilot and data powers, the optimal power allocation maximizing the data rate is obtai...

This study explored gender related perceptions among male and female pilots and the extent to which such perceptions may cause workplace stress, anxiety, or depression which may affect female pilots. This study utilized two measuring instruments on a sample that consisted of 83 pilots and a third instrument on a sample of 52 female pilots and non-pilots. The three measurement instruments used w...
