This study presents a novel technology, termed thermomorphic hydrophilicity base-induced precipitation (THBIP), for the effective removal of hardness ions from hypersaline brines with high-scaling propensity. THBIP utilizes thermoresponsive amine bases controlled scaling constituents in alkaline conditions and subsequently uses low-temperature heat to trigger phase separation aqueous solution, ...

Traffic model based on the fractional Brownian motion (fBm) contains three parameters: the mean rate , variance parameter and the Hurst parameter . The estimation of these parameters by the maximum likelihood (ML) method is studied. Explicit expressions for the ML estimates and  in terms of are given, as well as the expression for the log-likelihood function from which the estimate  is obtain...
