Advancement in information technology and enhancement of computing power has made possible application of modern and sophisticated sampling techniques like adaptive cluster sampling, bootstrapping, randomized response etc. in large socio-economic surveys. However, a good number of these have been developed for simple random sampling with replacement (SRSWR) only and thus cannot be applied to complex practical surveys. This book provides an account of improvements on as well as application of advanced statistical methods in practical complex surveys that predominantly use varying selection...

The dairy whey wastewater has been causing major environmental pollution problems in terms of high load of BOD (Biochemical Oxygen Demand) and COD (Chemical Oxygen Demand) and therefore leads to serious environmental pollution problems. Traditional business approaches involving different commercial processes such as employing membranes are followed to treat dairy whey. But the biggest challenges are the adverse effect of the whey proteins on membranes (membrane fouling) and operating conditions for the membrane performances are not optimized in any of the literatures and thus recovery of...
