This paper was aimed to study the efficiency of forward osmosis (FO) process as a new application for treatment wastewater from textile effluent and factors affecting performance process.The draw solutions used were magnesium chloride (MgCl2), aluminum sulphate (Al2 ( SO4)3 .18 H2O), feed reactive red, disperse blue dyes.Experimental work includes operating using thin film composite (TFC) membr...

The rejection of trace organic contaminants (TrOCs) by an osmotically driven membrane filtration process was investigated. A set of 40 compounds representing major groups of TrOCs of concern was selected for this study. The rejection of the TrOCs by a commercial cellulose acetate asymmetric forward osmosis membrane, as well as a ''tight'' commercial thin-film composite nanofiltration (NF) membr...

Two multivariable inferential feed-forward control strategies are proposed in this paper. In the first strategy, the effects of disturbances on the primary process variables are inferred from uncontrolled secondary process variables that are measured on-line. In the second approach, the effects of disturbances on the primary process variables are inferred from the manipulated variables for thos...

The main objective of this paper is to study the effect of extrusion parameters (extrusion stresses and temperature) and die geometry, i.e. extrusion radius, on the extruded aluminum quality using FEM Simulation Technique. For this purpose, the general FEA Software ABAQUS was used to set up the finite element model of the warm aluminum extrusion in two dimensions (2D). Aluminum alloy Al-2014 wa...

BACKGROUND A viable single cell is crucial for studies of single cell biology. In this paper, laser-induced forward transfer (LIFT) was used to isolate individual cell with a closed chamber designed to avoid contamination and maintain humidity. Hela cells were used to study the impact of laser pulse energy, laser spot size, sacrificed layer thickness and working distance. The size distribution,...

The abilty to continuously revise business practices is essential to organizations aiming at reducing their costs and increasing their revenues. Rapid and continuous changes to business processes result in less control over the executed activities. As a result, the ability of process designers to produce solid, well-validated work‡ow models is limited. Work‡ow management systems (WfMSs), servin...

We present a method for the sparse greedy approximation of Bayesian Gaussian process regression, featuring a novel heuristic for very fast forward selection. Our method is essentially as fast as an equivalent one which selects the “support” patterns at random, yet it can outperform random selection on hard curve fitting tasks. More importantly, it leads to a sufficiently stable approximation of...
