Treatment of Wastewater from Methylene Blue Dye and E. Coli Bacteria by High-Performance FeO/rGO/TiO Nanocatalyst.

Photocatalysis-based technology has insight into decreasing the disadvantages of traditional approaches and has been identified as an appropriate way to eliminate dyes and bacteria from wastewater. In this work, FeO/rGO/TiO photocatalyst material was synthesized by a simple and fast hydrothermal method. The photocatalyst process results showed that FeO/rGO/TiO nanocomposite degraded methylene blue dye completely in 4 min.

Uncertainty and spatial analysis in wheat yield prediction based on robust inclusive multiple models.

Reliable prediction of wheat yield ahead of harvest is a critical challenge for decision-makers along the supply chain. Predicting wheat yield is a real challenge for better agriculture and food security management. Modeling wheat yield is complex and challenging, so robust tools are needed.

A novel equation for longitudinal dispersion coefficient prediction based on the hybrid of SSMD and whale optimization algorithm.

The purpose of the present paper is improving the accuracy of existing formulas for the longitudinal dispersion coefficient (LDC) prediction based on a novel and simple meta-heuristic optimization method called Whale Optimization Algorithm (WOA). Although several existing formulas calculate LDC in the rivers based on the hydraulic and hydrodynamic specifications, most of them have significant errors in confronting extensive field data. In this study, comprehensive field data, including the geometrical and hydraulic properties of different rivers in the world, were adopted to build a reliable model.

Improving one-dimensional pollution dispersion modeling in rivers using ANFIS and ANN-based GA optimized models.

Simulation and prediction of the pollution transport is one of the major problems in environmental and rivers engineering studies. The numerical tools have been used in simulation of the concentration profile transmission for description of river water quality. The one-dimensional advection-dispersion equation (ADE) is used in applied water quality modeling and requires the accurate estimation of longitudinal dispersion coefficient (D).
