In the Bayer process, the reaction of silica in bauxite with caustic soda causes the loss of great amount of NaOH. In this research, the bound-soda losses in Bayer process solid residue (red mud) are predicted using intelligent techniques. This method, based on the application of regression and artificial neural networks (AAN), has been used to predict red mud bound-soda losses in Iran Alumina C...

the present research has been conducted to investigate the soda and soda-anthraquiuone pulping from whole kenaf (v36). in this respect, anatomical characteristics of kenaf bast and core fibers as well as the soda and soda-aq pulp properties produced at four sodium hydroxide concentrations, namely 25, 30, 35 and 40 (g/lit), have been evaluated. the pulping results indicated that pulp yield and k...
In this paper, we give two main technical results: (i) we show a stronger lower bound for substring search problem via compression extending results of Demaine and López-Ortiz (SODA ’01); (ii) improve the results of Gal and Miltersen (ICALP ’03) by showing a bound on the redundancy needed by the polynomial evaluation problem that is linear in terms of the information-theoretic minimum storage r...
The trace reconstruction problem is to reconstruct a string x of length n given m random subsequences where each subsequence is generated by deleting each character of x independently with probability p. Two natural questions are a) how large must m be as a function of n and p such that reconstruction is possible with high probability and b) how can this reconstruction be performed efficiently....
this study was conducted to compare the yield and strength properties of soda and kraft pulp produced from populus deltoeides sapwood and heartwood. initially fiber length, lignin content in both sapwood and heartwood were measured. then from either sapwood or heartwood pulps were prepared with using soda and kraft processes, handsheets were made from this pulp and mechanical properties were me...
In the present study, prediction of Alumina recovery efficiency (A.R.E), the amount of produced red mud (A.P.R), red mud settling rate (R.S.R) and bound-soda losses (B.S.L) in Bayer process red mud has been carried out for the first time in the field. These predictions are based on Lime to bauxite ratio and chemical analyses of bauxite and lime as Bayer process feed materials. Radial basis func...
We investigate coordination mechanisms that schedule n jobs on m unrelated machines. The objective is to minimize the latest completion of all jobs, i.e., the makespan. It is known that if the mechanism is non-preemptive, the price of anarchy is Ω(logm). Both Azar, Jain, and Mirrokni (SODA 2008) and Caragiannis (SODA 2009) raised the question whether it is possible to design a coordination mech...
OBJECTIVE This study aimed to compare diet soda drinkers, regular soda drinkers, and individuals who do not regularly consume soda on clinically significant eating disorder psychopathology, including binge eating, overeating, and purging. METHOD Participants (n=2077) were adult community volunteers who completed an online survey that included the Eating Disorder Examination Questionnaire and ...
We develop a new technique for constructing sparse graphs that allow us to prove nearlinear lower bounds on the round complexity of computing distances in the CONGEST model. Specifically, we show an Ω̃(n) lower bound for computing the diameter in sparse networks, which was previously known only for dense networks [Frishknecht et al., SODA 2012]. In fact, we can even modify our construction to ob...
