In moving biofilm membrane bioreactor (MB-MBR) sponge carriers for biofilm growth were coupled with conventional submerged membrane bioreactor (C-MBR). This study compared the fouling propensity of C-MBR with MB-MBR and investigated factors affecting fouling variations in both the systems. Membrane fouling tendencies were monitored in terms of(More)
Cooperative relaying has recently received significant attention due to its diversity gain, higher QoS, power savings, extended coverage and improved BER as compared to conventional SISO systems. For further improvement in the system performance, Hybrid ARQ proves itself as effective transmission strategy. Exploiting the retransmission nature of Hybrid ARQ,(More)
In this paper, we propose Self-Encoded Spread spectrum combined with cooperative diversity to combat against the effects of fading in wireless channel. Cooperative diversity technique is employed with the intention of achieving spatial diversity gain using relay nodes. After introducing iterative decoding in SESS we exploit its inherent temporal diversity,(More)
In this study, performance of laboratory-scale membrane bioreactor (MBR) was evaluated in treating high strength domestic wastewater under two nitrogen loading rates (NLR) i.e., 0.15 and 0.30 kg/m(3)/d in condition 1 and 2, respectively, while organic loading rate (OLR) was constant at 3 kg/m(3)/d in both conditions. Removal efficiencies of COD were above(More)
