This article presents an experimental investigation of OPW treatment for oil removal by integration of two processes: coalescer bed and microfiltration membranes (MF). The main goal is to reach an effluent quality good enough for injection, discharge or reuse in surface activities. The objective of processes combination is to overcome operational problems and limitations that both processes pre...

Clinical trials increasingly occured in Asia during the past years as pharmaceutical industries embraced globalization in the clinical research fields. The trend is true with phase III clinical trials but not for early stage/phase I clinical trials in Asian countries is still under-represented. The conduct of phase I clinical trials is considered more sophisticated and difficult than the later ...

In the commonly used DE/rand/1 variant of differential evolution the primary mechanism of generating new solutions is the perturbation of a randomly selected point by a difference vector. The newly selected point may, if good enough, then replace a solution from the current generation. As the replaced solution is not the one perturbed to create the new, candidate solution, when the population h...

In the last two decades, a number of methods have been proposed for forecasting based on fuzzy time series. Most of the fuzzy time series methods are presented for forecasting of car road accidents. However , the forecasting accuracy rates of the existing methods are not good enough. In this paper, we compared our proposed new method of fuzzy time series forecasting with existing methods. Our m...

The present paper addresses the problem of attainment of the supremums in various equivalent definitions of hereditary density hd and hereditary Lindelöf degree hL of Boolean algebras. We partially answer two problems of J. Donald Monk, [13, Problems 50, 54], showing consistency of different attainment behaviour and proving that (for the considered variants) this is the best result we can expec...
