[ 1 ] - مقایسه مدل ریاضی و شبکه عصبی مصنوعی در تخمین نسبت رطوبت برشهای پرتقال طی فرآیند خشکشدن
در تحقیق حاضر، خشککردن لایه نازک برشهای پرتقال در خشککن هوای داغ آزمایشگاهی مدلسازی گردید. فرایند خشککردن تحت شرایط متفاوت، سه دمای 50، 60 و 70 C° و سرعت جابهجایی هوای 0/1و 0/2 m/s انجام شد. آنالیز آماری دادهها نشان داد که تغییرات دما و سرعت جابهجایی هوا بر روی نسبت رطوبت اثرات معنیداری 05/0>p داشته، اما اثر متقابل دما و سرعت جابهجایی هوا، اثر معنیدار نداشته است. بنابر نتای...
[ 2 ] - Predicting the Coefficients of Antoine Equation Using the Artificial Neural Network (TECHNICAL NOTE)
Neural network is one of the new soft computing methods commonly used for prediction of the thermodynamic properties of pure fluids and mixtures. In this study, we have used this soft computing method to predict the coefficients of the Antoine vapor pressure equation. Three transfer functions of tan-sigmoid (tansig), log-sigmoid (logsig), and linear were used to evaluate the performance of diff...
[ 3 ] - Bubble Pressure Prediction of Reservoir Fluids using Artificial Neural Network and Support Vector Machine
Bubble point pressure is an important parameter in equilibrium calculations of reservoir fluids and having other applications in reservoir engineering. In this work, an artificial neural network (ANN) and a least square support vector machine (LS-SVM) have been used to predict the bubble point pressure of reservoir fluids. Also, the accuracy of the models have been compared to two-equation stat...
[ 4 ] - A Comparison Between GA and PSO Algorithms in Training ANN to Predict the Refractive Index of Binary Liquid Solutions
A total of 1099 data points consisting of alcohol-alcohol, alcohol-alkane, alkane-alkane, alcohol-amine and acid-acid binary solutions were collected from scientific literature to develop an appropriate artificial neural network (ANN) model. Temperature, molecular weight of the pure components, mole fraction of one component and the structural groups of the components were used as input paramet...
