Thus, determining the bubble diameter accurately is of crucial importance in the design and operation of an FBR. Various equations are available for calculating the bubble diameter in an FBR. It has been found in this study that these models show a large variation while predicting the experimentally measured bubble diameters. Accordingly, the present study proposes a new equation for computing the bubble diameter in a fluidized bed. This equation has been developed using an efficient, yet infrequently employed computational intelligence (CI)-based data-driven modelling method termed genetic programming (GP). The prediction and generalization performance of the GP-based equation has been compared with that of a number of currently available equations for computing the bubble diameter in a fluidized bed and the results obtained show a good performance by the newly developed equation.1 aSonolikar, R., R.1 aPatil, M., P.1 aMankar, R., B.1 aTambe, S., S.1 aKulkarni, B., D.  uhttps://library.ncl.res.in/content/bubble-size-prediction-gas-solid-fluidized-beds-using-genetic-programming01692nas a2200253   4500008004100000022001400041245011600055210006900171260000800240300001400248490000700262520086000269653000601129653000801135653002401143653003001167653001201197653001601209100002001225700002001245700002301265700002101288856012901309       2020                        eng d  a1735-147200aBiomass ashes as potent adsorbent for pesticide: prediction of adsorption capacity by artificial neural network0 aBiomass ashes as potent adsorbent for pesticide prediction of ad  cJUN  a3209-32160 v173 a<p>Biomass ashes are used for adsorption of herbicides from aqueous solution. A relationship between physicochemical properties of biomass ashes such as carbon-hydrogen-nitrogen content (CHN analysis), silica content and BET surface area with their adsorption capacity was established and modeled using artificial neural network. 2,4-Dichlorophenoxyacetic acid (2,4-D) a commonly used herbicide is chosen a representative for this study. The artificial neural network model was trained, validated and tested using 35 data sets and was equipped with nine neuron hidden layers having tansig (tangent sigmoid) transfer function and an output layer with purelin (purely linear) transfer function. This model can be used to predict 2,4-D removal efficacy of any biomass ash by knowing its physicochemical properties like C, H, N, Si and BET surface area.</p>
