چکیده
In the present article, a performance of optimized regularization network (RN) and adaptive neuro-fuzzy inference system (ANFIS) are compared with a conventional MATLAB multi-layer back propagation toolbox for prediction of carbon active iodine number as a function of impregnation ratio (2.5-4), activation temperature (660-850 ○C) and residence time (60-150 min). The networks were trained by resorting several sets of experimental data ordered with Design Expert software. All the anthracite-based samples were chemically activated with KOH at various preparation conditions for methane storage applications. An efficient LOOCV criterion were employed for training the optimal isotropic Gaussian regularization network. Around 20% of data sets were randomly selected for validation performance of all networks. Error analysis along with correlation coefficient demonstrate that ANFIS and MLP networks have a superior performances over entire training exemplars, while, optimized regularization network shows excellent performances on both training andvalidation exemplars with R2 0.9994 and 0.9970 and root mean squared error of 6.66 and 32.96 respectively. Hence, RN can be considered as a reliable tool for predicting iodine number of activated carbons versus several preparation factors for methane storage purposes.کلیدواژه ها

اطلاعات بیشتر در مورد COI
COI مخفف عبارت CIVILICA Object Identifier به معنی شناسه سیویلیکا برای اسناد است. COI کدی است که مطابق محل انتشار، به مقالات کنفرانسها و ژورنالهای داخل کشور به هنگام نمایه سازی بر روی پایگاه استنادی سیویلیکا اختصاص می یابد.
کد COI به مفهوم کد ملی اسناد نمایه شده در سیویلیکا است و کدی یکتا و ثابت است و به همین دلیل همواره قابلیت استناد و پیگیری دارد.
