A comparative study of artificial neural network (ANN) and multiple regression is made to predict the fat tail weight of Balouchi sheep from birth, weaning and finishing weights. A multilayer feed forward network with back propagation of error learning mechanism was used to predict the sheep body weight. The data (69 records) were randomly divided into two subsets. The first subset is the train...
اندازه گیری رطوبت حجمی خاک و آب قابل دسترس برای گیاهان در رشته های مختلف مانند خاکشناسی، هیدرولوژی و مهندسی آب بسیار مهم است. بنابراین بررسی متعدد رطوبت خاک و میزان قابل استفاده آن برای گیاه از مهم ترین موضوعات در علم رابطه آب، خاک وگیاه است. برای تعیین رطوبت از روش های مختلفی مانند روش مستقیم (روش وزنی) و روش های غیر مستقیم مانند استفاده از دستگاه tdr و شبکه های هوش مصنوعی مانند شبکه عصبی، فاز...
